DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to

FIGS. 1

,


2


and


3


, the motor operated stored energy circuit breaker system


1


comprises a circuit breaker assembly


100


, which may for example be rated for 630 Amperes as shown, and a motor operated stored energy circuit breaker assembly


200


. Of course, the circuit breaker assembly


100


may also be rated for 125 Amperes or 250 Amperes, as shown in

FIG. 4

, or any other suitably appropriate current rating. The motor operated stored energy circuit breaker assembly


200


has a molded thermoplastic external housing


543


, although any other suitably appropriate material may be used.




As will be discussed in further detail later, the assembly operates as follows: as shown in

FIGS. 8 and 14

, for example, a manual reset/charging operator handle


537


is used to reset and charge charging springs


516




a


and


516




b


of the motor operated stored energy circuit breaker assembly


200


. Using the manual reset/charging operator handle


537


to reset the motor operated stored energy circuit breaker assembly


200


causes the circuit breaker assembly


100


to go to its OFF position and the charging springs


516


are charged. When the manual reset/charging operator handle


537


is repeatedly and ratchetedly rotated or turned about ninety (90) degrees counter-clockwise and then back to its initial starting position, it causes a one-way or uni-directional clutch


519


to slip so that a worm gear


507


(see

FIG. 16

) does not rotate or otherwise move. Also, the described initial counter-clockwise movement of operator handle


537


causes handle clutch


519




b


to slip so that operator handle shaft


513


does not move, while the return clockwise movement of operator handle


537


grabs or locks operator handle shaft


513


and causes pinion gear clutch


519




a


(see

FIG. 16

) to slip with respect to the operator handle shaft


513


so that the worm


517


and worm gear


507


do not move. A manual/automatic lockout slide handle


546


allows local control of the motor operated stored energy circuit breaker assembly


200


when its manual/automatic lockout slide


550


is in the unlocked manual position and also allows some local control when the manual/automatic switch


550


is in the automatic position. In particular, an operator can actuate the ON and OFF buttons


548


and


609


, respectively. The ON switch


548


is used to release the charged springs


516




a


and


516




b


so as to force a toggle handle


103


of the circuit breaker assembly


100


to its ON position. In particular, the ON switch


548


causes actuation of a latch bell crank


561


so as to rotate D-shaft latch


544


, which releases main operator gear


515


allowing it to rotate so as to cause the circuit breaker toggle handle


103


to move to its ON position.




The circuit breaker assembly


100


may comprise a circuit breaker subassembly and a circuit breaker plug-in unit (not shown). The circuit breaker subassembly comprises a toggle handle


103


, circuit breaker lug openings or apertures and circuit breaker mounting openings or apertures. Although not shown, threaded copper studs may be passed through circuit breaker mounting openings or apertures and are received by tulip contacts in the plug-in unit so as to connect or mount the circuit breaker unit to the circuit breaker plug-in unit. In this way, a current path may be provided through the plug-in unit to the circuit breaker assembly. Further, and although not shown, the circuit breaker subassembly may further include a push-to-trip button, a trip current rating adjustment or setting (Ir) and a magnetic current adjustment or setting (Im) for a mag-latch in the circuit breaker subassembly.




As shown in

FIGS. 1

to


4


, and as is detailed in

FIG. 5

, the motor operated stored energy circuit breaker may have the following operating features:




If the selector bar or automatic/manual switch


550




s


is set to its manual position and the circuit breaker assembly


100


is OFF, then the charging springs


516




a


and


516




b


of the motor operated stored energy circuit breaker assembly


200


may be charged, the contacts of the circuit breaker assembly


100


are open, remote ON switch


548




r


and remote OFF/TRIP switch


609




r


are blocked, the local OFF/TRIP switch


609


does not trip the circuit breaker assembly


100


(which stays in its reset or OFF position), status indicator light pipe


534




b


indicates OFF/CHARGED and the motor operated stored energy circuit breaker assembly


200


can be locked electrically using automatic/manual switch


550




s


and/or mechanically using cylinder lock


618


. In its locked position, the unit cannot be operated either locally or remotely. In its unlocked position, the unit may be operated by pressing ON switch


548


, which closes the circuit breaker assembly


100


in less than on the order of about 100 milliseconds.




If the selector bar or automatic/manual switch


550




s


is set to its manual position and the circuit breaker assembly


100


is ON, then the charging springs


516




a


and


516




b


of the motor operated stored energy circuit breaker assembly


200


are discharged, the contacts of the circuit breaker assembly


100


are in their closed position, the remote ON and OFF/TRIP switches


548




r


and


609


, respectively, are blocked, the motor operated stored energy circuit breaker assembly


200


cannot be locked and the status indicator light pipe


534




a


indicates ON/DISCHARGED. In this state, the circuit breaker assembly


100


may be turned OFF by pushing local OFF/TRIP switch


609


, which may optionally actuate a bell alarm (not shown), on the circuit breaker assembly


100


. If there is control power, the OFF/TRIP switch


609


trips the circuit breaker assembly


100


and causes it to go to its OFF position. If there is no control power, the circuit breaker assembly


100


will trip but the status indicator light pipe


534




a


indicates ON/Discharged. If the stored energy assembly is wired through the optional bell alarm (not shown), when control power is restored, the motor operated stored energy assembly


200


is reset causing the circuit breaker assembly


100


to return to its OFF position. The operator charging/reset handle


537


may also be used to turn OFF the circuit breaker assembly


100


without actuating its bell alarm. If there is control power, the motor operated stored energy assembly


200


is set to its charged condition so that the circuit breaker assembly


100


is in its OFF position after a few strokes of the operator charging/reset handle


537


. If there is no control power, then continued stroking or ratcheting of the operator charging/reset handle


537


sets the motor operated stored energy assembly


200


to its charged condition so that charging springs


516


are charged and causes the circuit breaker assembly


100


to go to its OFF position. At this point, the charging/reset handle


537


is disengaged.




Optionally, if the stored energy assembly is wired through the optional bell alarm, and if the bell alarm (not shown) of the circuit breaker assembly


100


is actuated after a short circuit trip or under-voltage trip, then the motor operated stored energy assembly


200


may go to its CHARGED/RESET position so that the circuit breaker assembly


100


is set to its OFF position. If the circuit breaker assembly


100


trips by shunt trip, under voltage release, overload or short circuit, the motor operated stored energy assembly


200


does not change its position and the status indicator light pipe


534




a


would indicate ON. Also, the bell alarm (not shown) could be wired so as to actuate the OFF/TRIP switch


609


and charge the springs


516




a


and


516




b


.




If the selector bar or automatic/manual switch


550




s


is set to its automatic position, then when the circuit breaker assembly


100


is in its OFF position, the springs


516




a


and


516




b


are charged, the circuit breaker assembly


100


is closed, remote operation is not blocked, the unit cannot be locked, the status indicator light pipe


534




a


indicates ON/DISCHARGED and the charging/reset handle


537


is engaged. Since there is no local OFF control when automatic operation is enabled, the motor operated stored energy circuit breaker assembly


100


may be only be turned OFF by pushing the remote OFF switch


609




r


of FIG.


6


. Alternatively, of course, local control through the remote OFF switch


609




r


could be made available to the user if that was desired. If there is control power, the local OFF switch


609


of

FIG. 6

may be used to trip the circuit breaker assembly


100


and cause the toggle handle


103


of the motor operated stored energy assembly


200


to go to its OFF position. If there is no control power and the stored energy assembly is wired into the optional bell alarm (not shown), then the motor operated stored energy assembly


200


only goes to its OFF (charged) position when control power is restored. If the remote OFF switch


609




r


is actuated, the motor operated stored energy assembly


200


goes to its OFF (charged) position in less than on the order of about one (1) to five (5) is seconds. Unless the motor operated stored energy circuit breaker assembly


200


is connected to a bell alarm of the circuit breaker assembly


100


, the motor operated stored energy assembly


200


remains in its ON (uncharged) position if the circuit breaker assembly


100


trips by shunt trip or short. Using the charging/reset handle


537


to turn OFF the circuit breaker assembly


100


does not trip it, but will cause the motor operated stored energy assembly


200


to go to its OFF/CHARGED position if there is control power. If there is no control power, then the reset/charging handle


537


must be used to fully recharge the motor operated stored energy assembly


200


, thereby completing the charge cycle and causing the status indicator light pipe


534




b


to indicate OFF.




In the manual position, holding the ON and OFF/TRIP switches


548


and


609


, respectively, essentially simultaneously or at about the same time, causes the motor operated stored energy circuit breaker assembly


200


to cycle OFF and ON. To lock the motor operated stored energy assembly


200


using pad locks or key locks, the selector bar or automatic/manual switch


550




s


must be in its MANUAL position so as to lock out both electrical and mechanical operations of the motor operated stored energy circuit breaker assembly


200


using hasp


538


and a locking apparatus, such as a wire and seal or a locking cable (not shown). In the automatic (remote) position, as can be seen from

FIG. 7

, nothing will happen since the motor operated stored energy assembly


200


is only OFF or ON but cannot be both OFF and ON at essentially the same time.





FIG. 6

is a schematic view of the circuitry


1000


of the motor operated stored energy circuit breaker assembly


200


with a control module


1200


, while

FIG. 7

is a schematic view of the circuitry of the control module


1200


. As regards the above and as is shown in

FIG. 7

, a cam operated limit switch


531




a


having circuit breaker open position


1235


and circuit breaker closed position


1234


which operates the electric motor


521


when the circuit breaker assembly


100


is open and interrupts operation, is controlled by the release solenoid


532


, that is controlled by the relative position of the operator gear cam


515




c


of FIG.


15


. The automatic/manual switch


550




s


controls the operation of switches


535




a


and


535




b


(switches S


2


A and S


2


B). As shown, the locking hasp


538


may be used to inhibit operation of the OFF Switch


548


and automatic/manual switch


550




s


. Optionally, automatic recharging of the charging springs


516




a


and


516




b


after the circuit breaker assembly


100


trips may also be provided.




More specifically,

FIGS. 6 and 7

show an electronic circuit


1200


for causing the electric motor


521


on a motor operated stored energy circuit breaker assembly


200


to start and continue to run when a short duration signal of at least on the order of about ten milliseconds is applied. As discussed, the motor operated stored energy circuit breaker assembly


200


may have relatively fast circuit breaker closing times (for example, less than on the order of about 100 milliseconds) and a relatively slow opening cycle (for example, less than on the order of about one (1) to five (5) seconds). Also as discussed, the closing cycle is powered by the charging springs


516




a


and


516




b


, which are charged during the opening cycle by operating the electric motor


521


. Because the motor running time is relatively long and the motor starting signal is relatively short, it is believed that it may be desirable or even necessary, depending on the application, to have some way of supplying the current to the electric motor


521


after the motor starting signal is momentarily applied by solenoid


532


. While this may be done using an additional cam and limit switch in an alternative embodiment, it is believed to be preferable to use the electronic control module


1200


as described herein.




It is believed that the electronic control module


1200


may provide the following advantages: the electric motor


521


continues to run even if only a relatively short duration motor starting signal is applied; an extra cam and limit switch are not needed; there may be improved reliability and reduced cost; either a universal AC or a DC motor may be used; there should be reduced space requirements in the motor operated stored energy circuit breaker assembly


200


; it should be more difficult and more unlikely for a user to connect the wrong polarity wire when connecting power to the motor operated stored energy circuit breaker assembly


200


.





FIGS. 6 and 7

illustrate the electronic circuit assembly


1200


in which either AC or DC power may be supplied between terminals


1210




a


and


1210




b


. The current may be of either positive or negative polarity. As designed, it is intended that the electronic control module


1200


essentially keep electric current flowing through the motor when a set of electrical contacts between points


609




r


or


609


are momentarily closed.




In particular, when the motor operated stored energy circuit breaker assembly


200


is in its uncharged state so that the circuit breaker assembly


100


is closed to its ON position, cam operated limit switch


531


is in its closed circuit breaker position and contacts terminal


1234


. The position shown in

FIG. 7

is the open circuit breaker position. In this way, cam operated limit switch


531


allows current flow through the electric motor


521


. If there is an AC voltage between terminals


1210




a


and


1210




b


, it is converted to a full wave rectified DC signal by a bridge rectifier


1220


formed by diodes


1221


,


1222


,


1223


and


1224


. When either local OFF switch


609


or remote OFF switch


609




r


is momentarily closed, depending on the position of mechanical automatic/manual switch


550




s


and corresponding electrical switches


1260




a


and


1260




b


, current flows through a gate


1272


of SCR


1271


thereby turning it on. Current continues to flow through SCR


1271


until the electric motor


521


causes the circuit breaker assembly


100


to move to its OFF or open position. At this time, cam operated limit switch


531


moves from a first position


1234


, corresponding to a closed circuit breaker position, to a second position


1235


, corresponding to an open circuit breaker position, in series with solenoid


532


thereby stopping current flow through SCR


1271


and the electric motor


521


. Capacitor


1251


is intended to prevent the voltage across the SCR


1271


from going to or significantly approaching zero so as to turn off the SCR


1271


. Capacitor


1251


is selected such that the control module circuit


1200


works throughout an appropriate specified range, such as about 24 to 250 volts AC or DC, for certain class circuit breakers assemblies. Of course, the appropriate and specified range may be different for other class circuit breakers. As designed, it is believed that the control module circuit


1200


should operate correctly regardless of whether the input voltage is AC or DC and regardless of the voltage polarity.




More specifically, as shown in

FIG. 7

, the bridge rectifier


1220


comprising diodes


1221


,


1222


,


1223


and


1224


is parallel to capacitor


1251


. The bridge rectifier


1220


and capacitor


1251


are electrically connected to electric motor


521


. A first sub-circuit comprising resistor


1261


, capacitors


1253


and


1254


, and zener diode


1225


provides the input signal to trigger the SCR gate


1272


. In particular, resistor


1261


is in series with the parallel combination of capacitors


1253


and


1254


and zener diode


1225


. The electric motor


521


is connected between points


1243


and


1244


. Points


1241


and


1243


are common nodes for bridge rectifier diodes


1221


and


1222


and capacitor


1251


. A second subcircuit comprises capacitor


1252


in parallel with SCR


1271


, which has capacitor


1254


tied between its SCR gate


1272


and relative ground point


1242


. Terminal


1210




a


connects between bridge rectifier diodes


1221


and


1223


, while terminal


1210




b


connects between bridge rectifier diodes


1222


and


1224


. Finally, cam operated limit switch


531


may comprise an SPDT switch, where an inductor or solenoid


532


is connected between a second terminal


1235


of switch


531


(while terminal


1210




b


is connected to a first terminal of


1234


of switch


531


).

As is further shown in

FIGS. 1

,


2


,


8


,


9


,


11


,


17


,


19


and


20


, the main subassembly


400


comprises the operator reset/charging handle


537


, which may be manually rotated or ratcheted clockwise approximately 90 degrees from main external housing surface


534




p


to surface


543




m


, and is then returned by handle return spring


566


, which sits in spring slot


565




b


of handle hub


565


. Also, roll pin


595


fits in roll pin aperture


565




d


of handle hub


565


to provide an attachment point for handle return spring


566


. The handle rotation action drives a pinion gear carrier block shaft


513


through associated overrunning unidirectional clutch


519




b


so as to rotate pinion gear carrier block


536


clockwise about pivot point or shaft aperture


536




a


until a tapered or triangular end


536




c


meets and is stopped by a pinion gear carrier block stop


557


mounted in lower and upper housing


510


and


512


. If the stored energy main springs


516




a


and


516




b


are not fully charged, the gear carrier block


536


carries or moves driver/pinion gear


518




s


and idler/pinion gear


518




a


into contact with the main charging operator gear


515


. When actuated, the pinion gears


518


rotate the main charging operator gear


515


clockwise so as to move cyclically and clockwise the pin cam follower


542


within a pin or cam follower aperture


504




m


on the drive connector plate


504


so as to charge the springs


516


.




As shown in

FIG. 15

, the main charging operator gear


515


only has missing gear teeth


515




t


through in the order of about more than one-half of its circumference so that the idler/pinion gear


518




a


cooperating with the driver/pinion gear


518




s


only drives, moves or rotates the pin or cam follower


542


on the order of about a few degrees past a position that is top dead center. In particular, teeth


515




t


on the main charging operator gear


515


only cover on the order of about one-half of the operator gear circumference. In the specific embodiment, the operator gear


515


comprises twenty adjacent or contiguous operator gear teeth that fit in a thirty-two gear tooth pattern. That is, twelve gear teeth are missing from the thirty-two gear tooth pattern so that on the order of about sixty-two and one-half percent (62.5%) of the operator gear


515


has operator gear teeth so that there is almost a thirty-two and one-half percent (32.5%) gap. Also, further rotating the manual reset/charging handle


537


rotates the pinion gear carrier block


536


no more than the driver/pinion gear


518




s


. To indicate that the charging action is complete, the force required to operate the manual operator reset/charging handle


537


is noticeably reduced. When the main charging gear


515


has been driven as far as possible by the driver/pinion gear


518




s


, the force of the main charging springs


516




a


and


516




b


causes the main charging gear


515


to continue to rotate until its rotation is stopped by the D-shaped cylindrical latch assembly


640


. By moving in pin cam follower aperture


504




m


on the drive connector plate


504


, the cyclic motion of the pin cam follower


542


causes the drive connector plate


504


and the slide plate


522


to move linearly as guided by the guide or toggle slide shafts


503




a


and


503




b


. The linear motion of the drive connector plate


504


moves the circuit breaker toggle handle


103


so as to open the main contacts (not shown) of the circuit breaker assembly


100


, thereby driving the motor operated stored energy circuit breaker assembly


200


into its reset and ready to close position. The linear motion of the drive connector plate


504


and the slide plate


522


also stretches or charges the operating springs


516




a


and


516




b


which are secured between the drive connector plate


504


and the main internal housing


511


, as previously discussed. In this way, the energy stored in the operating springs


516




a


and


516




b


may later be used to quickly close the main contacts of the circuit breaker assembly


100


.

. Horizontal lifter member


552




c


is insertedly fitted through horizontal lifter aperture


538




i


of locking hasp member


538




e


of locking hasp


538


. Thus, when a user turns a key


618




a


so as to rotate clockwise cylinder lock arm


613


from its left oriented horizontal position to a perpendicularly oriented position, the cylinder lock arm


613


rotateably moves lifter


552


upwardly so that horizontal lifter member


552




c


slides upwardly and transversely from left to right thereby lifting locking hasp member


538

dd


. The button switch


614




a


of straight lever switch


614


is positioned adjacent to the vertical member


553




b


of trip rod


553


. When activated, the OFF/TRIP button


609


forces trip rod


553


forward so as to cause trip rod member


553




c


to actuate a trip button (

FIG. 24

) on the circuit breaker assembly


100


, and vertical member


553




b


actuates straight lever switch


614


so as to cause the electric motor


521


to drive the circuit breaker assembly to its OFF position, as shown in

FIGS. 6 and 7

. To avoid actuating the trip button, a screw or other suitably appropriate limit apparatus (not shown) may be mounted adjacent that vertical trip rod member


553




b


and the button switch


614




a


of straight lever switch


614


so as to limit movement of the trip rod


553


so as to allow actuation of the local OFF operation using electric motor


521


but prevent tripping of the circuit breaker assembly


100


.




A D-shaped latch assembly


640


is shown in

FIGS. 8

,

, latch bellcrank


561


, bellcrank return spring


560


, bellcrank pivot bushing


547


, bellcrank pivot shaft


562


and push-on retainer


587


.




Referring again to the referenced Figures, including

FIGS. 25A and 25B

, the dowel pin


617


is inserted through dowel pin receiving apertures


545




a


and


545




b


of latch lever


545


and further inserted in a dowel pin receiving aperture (not shown) of D-shaped latch


544


. The latch


544


has a D-shaped or cylindrical member


544




a


integrally associated with partial cylindrical member


544




b


having a flat surface


544




c


perpendicularly oriented with respect to semi-circular outer end surface


544




e


of partial cylindrical member


544




b


and to semi-circular end surface


544




d


of cylindrical member


544




a


. A roll pin


593


is also insertedly fitted into a roll pin aperture (not shown) in D-shaped latch


544


and the generally tapered or triangular shaped latch lever end


545




e


of latch lever


545


. The latch lever spacer


581


shown in the referenced Figures fits over the dowel pin


617


so as to space the partially cylindrical latch lever member


544




b


with respect to the inner surfaces of the upper gear housing


512


and the lower gear housing


510


. Latch lever


545


also has a rectangular shaped hasp interfering member


545




d


, which partially fits in hasp interfering aperture


5381


of hasp


538


. The hasp interfering member


545




d


is integrally associated with and is perpendicularly oriented with respect to partially semi-circular latch lever member


545




c


.




Solenoid link pin


576


is used to rotateably connect or link the tapered end of latch lever


545


to an end


533




a


(having a solenoid link pin aperture) of solenoid link


3533


. Another end


533




b


(having a solenoid plunger connecting aperture


533




d


) is operably connected or linked to a slotted aperture (not shown) at end


532




g


to solenoid cylindrical plunger


532


using a roll pin


594


and solenoid roll pin aperture


532




e


. A solenoid end


532




f


is designed to fit within a solenoid plunger


532




a


receiving aperture (not shown) of solenoid


532




b


. Solenoid spring


578


operates to apply force to the solenoid plunger


532




a


so that it moves outwardly from solenoid


532




b


and to its original position. The ON push-button switch


548


, which is used to actuate the D-latch assembly


640


and the solenoid


532


, is also returned to its original position by the force of solenoid plunger spring


578


. The solenoid


532


is mounted at an appropriate angle on the outside surface of lower gear housing


512


using solenoid mounting apertures


532




h


and


532




i


and appropriate fastening apparatus, such as screws


607


and spacer


532




s


, and lower gear solenoid mounting apertures


510




x


and


510




w.






The D-shaped latch assembly


640


operates as follows: when the operator pushes the ON push button switch


548


, it depresses push button rod


564


through push button rod aperture


512




u


of upper gear housing


512


so as to actuate latch bell crank


561


, thereby rotating D-shaped latch


544


which releases latch plate


574


so as to allow operator gear


515


to rotate, thereby allowing the charged main springs


516


to release so as to force drive connector


504


and slide plate


522


upwardly so as to move the toggle handle


103


of the circuit breaker assembly


100


from its OFF position to its ON position.




In particular, the latch bellcrank


561


comprises a mounting surface


561




a


and two perpendicular rectangular flanges, namely a push button rod flange


561




b


and a solenoid link pin flange


561




c


, as well as a rotateable bellcrank latch mounting pin aperture (not shown), which receives bellcrank lath pivot bushing


547


, bellcrank return spring


560


and bellcrank latch pivot shaft


562


, which is secured on the bellcrank latch mounting flange


512




hh


of upper gear housing


512


using push-on retainer


587


.




As discussed, the push button rod


564


pushes the push button flange


561




b


of bellcrank latch


561


so that it pivots about pivot bushing


547


, pivot shaft


562


as well as bellcrank return spring


560


which resists the clockwise rotation of bellcrank latch


561


. As the bellcrank latch rotates clockwise, solenoid link pin flange


561




c


pushes solenoid link pin


576


, located in the tapered end


545




e


of latch lever


545


so as to rotate clockwise latch


544


, dowel pin


617


and spacer


581


. In this way, the D-shaped latch member


544




b


of latch


544


also rotates clockwise so that it no longer interferes with latch stop


5741


on latch plate


574


. As a result, the latch plate


574


and the operator gear


515


may rotate, as discussed above and as shown in

FIGS. 23

to


25


.




Also, when the ON push button switch


548


is actuated so as to depress ON button rod


564


and partially rotate clockwise D-shaped latch assembly


640


, rectangular shaped hasp interfering member


545


rotates into slotted aperture


5381


of hasp


538


. In this way, hasp


538


is prevented from being removed while the stored energy circuit breaker assembly


200


moves the toggle handle


103


of the circuit breaker assembly


100


to its ON position.




As discussed, and as is shown in

FIGS. 8

,


9


,


11


,


14


to


22


, is a pinion gear assembly comprising pinion gear carrier


536


, which is used to mount driver/pinion gear


518




s


and idler/pinion gear


518




a


. Operator handle/pinion shaft aperture


510




b


in lower gear housing plate


510


is used to receive the operator handle/pinion shaft


513


. Pinion gear carrier post or stop


557


projects perpendicularly from the inside surface of lower gear housing


510


towards main housing


511


, and is used to limit rotational movement of charge gear carrier


536


, as is discussed further below. The main operator gear


515


has a kickout cam or latch plate


574


and a cam following pin or post structure


542


, which fits within cam following aperture


504




m


of drive connector


504


. Cam following pin or post structure


542


moves horizontally within cam following aperture


504


of drive connector or slide plate


504


so as to cause the drive connector or slide plate


504


to move linearly and vertically.




Also shown in

FIGS. 2

,


3


,


6


,


8


,


9


,


11


,


15


and


16


are a manual/auto lockout slide plate


550


having a locking extension member


550




a


. As discussed, locking hasp vertically slotted apertures


510




t


and


512




t


receives locking hasp


538


. Manual/auto lockout slide plate


550


has a lockout slide retainer


555


which is secured by placing securing end


555




b


in lock slide retainer aperture


550




b


using retainer


597


fitted in circumferential slot


555




c


so that button end


555




a


projects outwardly through generally oval shaped lock slide retainer aperture


512




w


of upper gear housing


512


. A manual/auto lockout slide handle


546


(secured by retainer


597


), which a user may grasp and slide horizontally to move the manual/auto slide plate


750


between its left or manual and right or automatic positions, is secured by using retainer


597


to retain securing end


546




b


in lockout slide handle aperture


550




e


and allowing handle end


546




a


to project through upper gear housing lockout slide handle aperture


512




ff


and main external housing lockout slide handle aperture


543




g


. Both lockout slide retainer


555


and manual auto lockout slide handle


546


are securely associated with lockout slide plate


550


using shoulder rivets or any other suitably appropriate securing apparatus. If the manual/auto lockout slide handle


546


is in its manual position, a user may operate OFF button


609


and ON button


548


. If the manual/auto lockout slide handle


546


is in its automatic position, then a user cannot actuate OFF button


609


or ON button


548


, which are blocked by the “automatic” position of the manual/auto lockout slide handle


550


.




OFF button


609


receives and actuates trip rod


553


through trip rod aperture


512




d


of upper gear housing


512


. ON button


548


receives and actuates ON button rod


564


through ON button rod aperture


512




u


. Also, the ON button legs


548




x


and


548




xx


fit in ON button leg apertures


512




x


and


512




xx


of upper gear housing


512


to allow ON button


548


to be depressed in the manual position when ON button leg lockout slide aperture


550




c


is aligned with ON button leg aperture


512




x


of upper gear housing


512


. When the manual/auto lockout slide plate


550


is in its first or left manual position, then the ON button


548


and the OFF button


609


cannot be depressed because the lockout slide plate


550


interferes with the depression of those buttons since the lockout slide button apertures are not aligned with the corresponding apertures in the upper gear housing


512


. When the manual/auto lockout slide is moved to the right so that it is in its automatic position, button switch flange


550




g


depresses an actuation button (not shown) of button switches


535




a


and


535




b


(see

FIG. 6

) which are also switches S


2


A and S


2


B of the electrical schematics shown in

FIGS. 6 and 7

. Thus, switches


535




a


(S


2


A) and


535




b


(S


2


B) are open when the manual/auto lockout slide


550


is in its manual position, and they are closed for automatic operation when the manual auto lockout slide


550


is in its automatic position.




Finally, the manual/auto lockout slide


550


is biased or restrained in either its manual or automatic position using two lockout slide spring pins


563


, lockout slide toggle pin


554


and lockout slide toggle spring


558


. In particular, lockout slide spring pins fit in lower and upper lockout slide spring pin apertures


512




y


while lockout slide toggle pin


554


fits in lockout slide toggle pin aperture


550




z


of lockout slide


550


and further projects through oval-shaped upper gear housing lockout slide pin aperture


512




z


. Also, each lockout slide spring pin


563


fit into lockout upper and lower slide pin spring aperture


558




y


and lockout slide toggle pin


554


fits in middle lockout slide toggle pin spring aperture


558




z


. In this way, the lockout slide


550


is biased into either its manual or automatic positions using the lockout slide toggle spring.




When the charging springs


516




a


and


516




b


are fully charged, the main contact of the circuit breaker assembly


100


may be either manually or electrically closed as follows. As discussed, pressing ON button


548


causes the D-latch assembly


544


to rotate clockwise so that latch


5741


of latch plate


574


is free to rotate clockwise past the flat surface of D-latch


544


. As discussed, this allows the main operator gear


515


to rotate and the drive connector or slide plate


504


to move relatively rapidly in an upward direction so as to force the toggle handle


103


of the circuit breaker assembly


100


to its ON position using toggle handle slide


522


.




When the charging springs


516




a


and


516




b


are not fully charged, electrical operation is as follows:




When electric power is applied, an electric motor


510


is used to drive a reduction gear assembly


630


, which rotates a worm


517


and corresponding worm gear


507


, which drives handle/pinion shaft


513


through unidirectional clutches


519




a


and


519




b


as previously discussed. The shaft


513


rotates until charge gear carrier


536


is stopped by the charge gear block stop


557




a


. The charge gear carrier


536


carries driver/pinion gear


518




s


and idler/pinion gear


518




a


into contact with a main charging or operator gear


515


if the stored energy operating mechanism or charging springs


516




a


and


516




b


are not fully charged. The idler/pinion gear


518




a


then rotates the main charging gear


515


clockwise so as to carry the pin/cam follower


542


in a cyclic motion, which is translated into linear motion of the drive connector or slide plate


504


. The main charging gear


515


has twelve teeth


515




t


missing out of a thirty-two gear tooth pattern so that the idler/pinion gear


518




a


is only able to drive the main charging gear


515


to a point or position where the pin/cam follower


542


has been carried a few degrees past the position of top dead center of the main operator gear


515


or in the proper overcenter position. This also allows the electric motor


521


to coast to its resting position so that it is not necessary to electrically or mechanically brake the electric motor


521


.




When the main charging gear


515


has been driven as far as the idler/pinion and driver/pinion gears


518




a




518




s


may drive it, the force of the operating springs


516




a


and


516




b


causes it to continue to rotate until the latch


5741


of latch plate


574


catches D-latch


544


so as to stop its rotation. By moving laterally in a horizontal slot operator


504




m


in the drive connector or slide plate


504


, the cyclic motion of the pin/cam follower


542


causes the drive connector


504


and the toggle handle slide


522


to move linearly as guided by the guide rods or slide shafts


503




a


and


503




b


. The linear motion of the drive connector


504


moves the toggle handle


103


of the circuit breaker assembly


100


so as to open the main contacts of the circuit breaker assembly


100


. The linear motion of the drive connector


522


also stretches or charges the charging springs


516




a


and


516




b


, which are attached, secured or otherwise fastened between slotted apertures of drive connector


504


and anchor points of main housing assembly plate


511


as previously discussed. In this way, the energy stored in the charging operating springs


516


may be used to close relatively rapidly the main contacts of the circuit breaker assembly


100


by forcing the circuit breaker toggle handle


101


to its ON position.
