Description




BACKGROUND OF THE INVENTION




1) Field of the Invention




The present invention relates to a device for lubricating railroad rails which is mountable to a track vehicle.




2) Description of the Prior Art




It has long been the practice to apply grease, friction modifying materials or similar gel-like lubricants to the sides of rails at curves, switches and other parts of the railroad track. Such materials are applied to the sides of the rail to reduce the friction which occurs as the flanges of the train's wheels contact the sides of the rail. Lubricants and/or friction controlling gels are also applied to the top of the rail. The friction reduction results in reduction of wear of both the rail and the wheels and reduces fuel consumption of the locomotion of the train and reduces squealing noises.




Devices for lubricating rails are already known, such as U.S. Pat. No. 5,687,814. Typically, these devices for lubricating rails are mounted on a track vehicle, such as a pickup truck equipped with additional flanged wheels. The lubricating nozzle of the device is secured to a rail gear mounted to a truck body.




As shown in

FIG. 1A

, preferably, devices for lubricating rails should direct lubricants


1


and


2


along a straight line at a constant fixed distance as measured from a head of a rail


3


and along a straight line at the top of the head. However, due to the suspension of the track vehicle and the varying weight of the vehicle due to varying loads, the positions of the lubricants


1


′ and


2


′ vary on the rail


3


′ as shown in FIG.


1


B. These varying positions of the lubricants can cause excessive waste, inefficient lubricant use and locomotion traction problems if the lubricant is mistakenly placed on the top of the rails.




Therefore, it is an object of the present invention to provide a device for lubricating a rail that can accurately apply lubricant and/or friction modifying material to a rail.




SUMMARY OF THE INVENTION




The present invention is a device for lubricating a rail that includes a mounting frame, a first support frame, a roller and a lubricating nozzle. The first support frame includes a first end and a second end. The second end is pivotally secured to the mounting frame. The roller is rotatably secured to the first end of the first support frame and is adapted to ride on a rail. The roller is adapted to rotate about a first axis relative to the first support frame. The lubricating nozzle is mounted to the first support frame for directing lubricant toward a rail.




The device for lubricating a rail can further include a biasing member having two ends, one end mounted to the mounting frame and the other end mounted to the support frame. The biasing member assists in maintaining the support frame in a first position and a second position. The first position maintains the roller in an engaged position with a rail and the second position maintains the roller in a disengaged position. The biasing member can include a gas charged chamber and a piston slidably received by the chamber, where the piston is biased relative to the chamber.




The roller can include a tapered surface defining a recess adapted to receive a portion of the rail. The tapered surface can include a first tapered surface spaced apart from a second tapered surface. The first tapered surface may be dissimilar from the second surface.




Preferably, the first tapered surface and the second tapered surface are frusto-conical shaped and have differing base diameters. More preferably, the roller is made of an electrically insulating material.




Preferably, the first support frame is pivotally secured to the mounting frame and pivots about a second axis parallel to the first axis. Alternatively, the first support frame may be secured to the mounting frame to pivot about a second axis which is not parallel to the first axis. The mounting frame can include a pivot bracket pivotably secured to a mounting bracket frame. The second end of the first support frame is pivotably secured to the pivot bracket. The pivot bracket in the first support frame pivots about a second axis relative to the mounting bracket frame and the first support frame pivots about a third axis relative to the pivot bracket, wherein the first axis and third axis are parallel to each other and the second axis is not parallel to the first axis and the third




A stop may be secured to one of the mounting bracket frames and the pivot bracket. The stop is adapted to contact the other of the pivot bracket and the mounting bracket frame to limit pivotal movement of the pivot bracket relative to the mounting bracket frame. The stop is adjustable to limit pivotal movement of the pivot bracket relative to the mounting bracket frame. The stop may be a threaded member threadably received by the pivot bracket.




The present invention may also include a second lubricating nozzle mounted to the first support frame for directing a lubricant toward a rail. One of the nozzles is arranged to direct lubricant toward the top portion of the rail and the other of the lubricating nozzles arranged to direct a lubricant toward a side portion or gage face of the rail. Preferably, the first support frame includes two spaced apart arms wherein the roller is positioned between the arms. The present invention may further include a centering spring having two ends, one end secured to the mounting bracket frame and the other end mounted to the pivot bracket. The centering spring may be a torsional spring.




The present invention may further include a bumper to which the mounting frame is secured. A second mounting frame may be secured to the bumper. A second support frame is secured to the second mounting frame. A roller is rotatably secured to the second support frame and a lubricating nozzle is mounted to the second support frame for directing lubricant toward a rail, wherein the mounting frames are spaced apart from each other.




The present invention is also a combination that includes the above-described device for lubricating the rail and a wheeled vehicle having a bumper, wherein the device for lubricating the rail is mounted to the bumper.

are made of an electrically insulating material. In this arrangement, the pivot bracket


46


and mounting bracket frame


44


can pivot relative to each other about the Y-axis. Tabs T are provided at the second end


41


of the frame


16


on respective arms


18


and

Referring back to

FIG. 10

, preferably the roller


24


is made of an electrically insulating material such as uhmw polyethylene. The roller


24


includes a roller surface


94


that includes a first tapered surface


96


spaced apart from a second tapered surface


98


. A cylindrical surface


100


is positioned between the first tapered surface


96


and the second tapered surface


98


. A recess


102


is defined between the first tapered surface


96


, the second tapered surface


98


and the cylindrical surface


100


. The roller


24


is adapted to contact the top portion


3


A of the rail


3


on the first tapered surface


96


and second tapered surface


98


within the recess


102


. The tapered surfaces


96


and


98


permit alignment of the roller


24


with the rail


3


.




As can be seen in

FIG. 10

, the tapered surfaces


96


and


98


are dissimilar. Specifically, the tapered surfaces


96


and


98


are frusto-conical in shape having the same interior smaller diameters d and d′ but differing larger exterior base diameters D and D′. Preferably, the larger base diameter tapered surface D′ is positioned along the inner surfaces I of the rail


3


. The roller


24


also includes cylindrical portions C and C′ which are positioned adjacent tapered portions


96


and


98


.




The operation of the rail lubricator device


10


will now be discussed. First, the bumper


12


is secured to the pickup truck


4


. Two rail lubricators


10


are spaced apart and secured to the bumper (preferably at the rear of the pickup truck


4


) through bolts passing through the rear plate


66


of the mounting bracket frame


44


and the slots


14


and as shown in

FIGS. 2 and 3

. The rail lubricators


10


can be slightly adjusted on the bumper


12


through tolerances of the respective slots


14


so that the rollers


24


are positioned directly above respective rails


3


. Once the rail lubricators


10


are secured to the bumper


12


via the bolts, then a rail lubricator arrangement


200


is formed.




The gas springs


84


and


86


are configured so as to apply pushing force P against the arms


18


and


20


, as shown in FIG.


6


. This will cause the frames


16


to be pushed downwardly toward the rail


3


, as shown in

FIG. 17

, in a first or engaged position


104


. In the first or engaged position


104


, the rollers


24


engage with the rail


3


and the gas springs


84


and


86


apply a downward force P against the frame


16


so as to maintain the rollers


24


in engagement with the rails. The rail lubricators


10


can then be activated by applying pressure, via a pump to the friction modifier supply


8


so as to supply friction modifying material to nozzles


34


and


36


, whereby friction modifying material can be applied to the top or side of the rail


3


or both. The gas springs


84


and


86


also assist in maintaining the rollers


24


in engagement should rollers


24


engage a bump or inconsistency on the rail


3


. Further, the pivot frame


42


permits the frame


16


to rotate about the shaft


68


(and the Y-axis) so as to permit the roller


24


to turn as the track weaves and bends.




After lubrication is complete, an operator may grab the handles


110


and pivot the frames


16


about the pivot pin


74


(and about the Z-axis) to first a second or intermediate position


106


and then to a third or disengaged position


108


, which is a position disengaged from the rail, as shown in

FIGS. 18 and 19

, respectively. Due to the arrangement of the gas springs


84


and


86


known as an over the center arrangement, the frame


16


is maintained in the disengaged position


108


because the gas springs


84


and


86


again apply a pushing force P toward the frame


16


. The pickup truck


4


can now continue either on the rails


3


or on the road without the lubricators


10


engaged with the rails


3


. This arrangement will prolong the life of the rollers


24


. Further, preferably, the frame


16


maintains the disengaged position


108


by placing the lock pins


81


and


82


through the holes


83


A and


83


B and the holes defined in the tabs of plates


52


and


54


. When the lubricators


10


are to be engaged with the rails


3


, then the lock pins


81


and


82


are removed and the operator moves the frame


16


from the disengaged third position


108


to the first position


104


via the handles


110


.




The present invention results in lubricant applied accurately to the rails


3


. The use of the gas springs permits proper engagement of the rollers


24


with the rails


3


and applies a pushing force P against the frames


16


so as to maintain the rollers


24


engagement with the rails


3


. Further, the arrangement of the gas springs


84


and


86


permit the frame to be maintained in a disengaged position


108


as well as the engaged position


104


. Finally, the pivot frame


42


permits the frames


16


to pivot when the pickup truck


4


makes turns on the rails


3


resulting in improved performance of the lubricators


10


and results in minimum wear of the rollers


24


. Alternatively, extension springs can be provided in lieu of the gas springs


84


and


86


.




An optional centering spring such as a torsional spring S, shown in phantom, may be provided and have one end secured between the face plate


48


and another end secured to the upper plate


62


so that the pivot bracket


46


can be maintained in a central or straight position as shown in FIG.


5


. In this manner, a rotational force or torsional force will be applied to the pivot bracket


46


, and in turn the frame


16


, should the pivot bracket


46


pivot or move from the central or straight position. This will minimize the tendency of the roller


24


to leave the rails


3


due to sharp turns of the rails


3


. Alternatively, a standard flanged rail wheel can be provided in lieu of the roller


24


and an extension spring Q, shown in phantom in

FIG. 5

, can be provided secured to plates


56


and


66


so as to abut the flange against the rail


3


.

FIGS. 19A-19C

show such a flanged wheel F and

FIG. 19D

shows the extension spring Q. Finally, the stops


58


and


60


are threaded members, which are threadably adjustable to limit the pivotable movement of the pivot bracket


46


relative to the mounting bracket frame


44


. Should the pivot bracket


46


rotate above a fixed value, the stops


58


and


60


will contact rear plate


64


preventing additional rotation about the shaft


68


. Alternatively, the stops


58


and


60


could be provided on the rear plate


64


to contact the pivot bracket


46


to limit rotation.





FIGS. 20-25

show a second embodiment of rail lubricator


200


made in accordance with the present invention. The rail lubricator


200


is similar to the rail lubricator


10


, except for the below noted differences. Like reference numerals will be used for like parts. Handles


210


are positioned closer to the first end


30


of the frame


16


of the rail lubricator


200


than the rail lubricator


10


.




The rail lubricator


200


includes a nozzle assembly


220


that differs from the nozzle assembly


32


of the rail lubricator


10


. Specifically, the nozzle assembly


220


includes two extension channels


222


extending forwardly from the arms


18


and


20


. A bar stock


224


is secured to the channels


222


. A clamp mounting channel


226


is secured to the bar stock


224


. A nozzle clamp


228


is slidably received by the clamp mounting channel


226


. Such an arrangement is manufactured by Stauff Corporation of 7WM Demerest Pl., Waldick, N.J. 07463, U.S.A. A nozzle


230


is secured to the nozzle clamp


228


. The position of the nozzle


230


relative to the rail


3


is adjusted by sliding the nozzle clamp


228


in the mounting channel


226


.




A further difference between the rail lubricator


200


and rail lubricator


10


is the inclusion of a stiffening brace


232


secured to the arms


18


and


20


. Furthermore, tabs T are eliminated in the rail lubricator


200


.





FIGS. 26 and 27

show another arrangement of a rail lubricator


300


that incorporates the features of the rail lubricator


200


except that it can swivel about the Y-axis with the lubricator in a horizontal position, such as shown in

FIG. 27

, and moved in a stowed position, substantially parallel to a tail gate or bumper of a vehicle. In this arrangement, the bumper


12


extends along an axis A and the frame


16


is adapted to be pivoted about the second end so that the frame


16


extends along an axis B parallel to the axis A. The bumper


12


extends along so that the frame


16


is in a stowed position. A removable pin P is provided for coacting with the mounting frame


46


and the frame


16


to maintain the frame


16


in the stowed position.




Having described the presently preferred embodiments of the present invention, it is to be understood that it may otherwise be embodied within the scope of the appended claims.
