Abstract
A rail brace assembly for bracing a rail with respect to a tie plate. The rail brace assembly includes a brace member, a locking member, a retention member and a spring clip fastener. The brace member has a top surface adapted to engage a head fishing surface of the rail, a bottom surface adapted to engage a base fishing surface of the rail, a front friction surface and an outwardly extending toe. The retention member is adapted to be attached to the tie plate and includes a bore adapted to receive a first end of the fastener and a recess adapted to receive the toe of the brace member to thereby prevent vertical movement of the brace member and the rail. The locking member has a front surface, a rear friction surface adapted to engage the front friction surface of the brace member, and a pair of spaced apart outwardly extending legs which straddle the retention member. A first end of the fastener is inserted into the bore of the retention member and a second end of the fastener biases the rear friction surface of the locking member into interlocking engagement with the front friction surface of the brace member to thereby inhibit lateral movement of the brace member with respect to the locking member.
Description




BACKGROUND OF THE INVENTION




The present invention is directed to a rail brace assembly for bracing and securing a rail to a tie plate, and in particular to a rail brace assembly including a brace member which braces the rail against lateral, rotational and vertical movement.




Rail braces are used to brace or buttress railroad rails against side thrust forces exerted by the wheels of rail traffic that would rotate or overturn the rail if not resisted. Side thrust forces of a magnitude sufficient to overturn a rail most commonly occur at curved sections of the rail which are subjected to high speed rail traffic. Rail braces typically utilize nuts and bolts, or resilient spring clips, for securing a brace to the tie plate and for applying a horizontal restraining force to the rail. The use of nuts and bolts presents a problem in that threads can be stripped, nuts can become loose, alignment of bolts in bolt holes can be difficult and time consuming, and wrenches are required for installation. Current boltless braces utilizing spring clips do not provide for vertical retention of the rail other than by the biasing force that is provided by the spring clip itself. As a result, when current boltless braces are utilized a rail can be pulled out of its rail seat during handling, and especially during tamping. The present invention overcomes these problems.




SUMMARY OF THE INVENTION




A rail brace assembly for bracing a rail that is located in the seat of a tie plate and for securing the rail to the tie plate. The rail includes a head fishing surface and a base fishing surface. The rail brace assembly includes a brace member having a top surface adapted to engage the head fishing surface of the rail, a bottom surface adapted to engage the base fishing surface of the rail, a front friction surface including a plurality of elongate ridges that form a corrugated surface, and an outwardly extending toe having an upper surface and an angled side surface. The rail brace assembly also includes a locking member having a front surface, a rear friction surface having a plurality of spaced apart ridges which form a corrugated surface that is adapted to engage the front friction surface of the brace member, and first and second spaced apart outwardly extending legs. The rail brace assembly also includes a retention member adapted to be attached to the tie plate that includes a bore and a recess adapted to receive the toe of the brace member. The legs of the locking member arc adapted to be located on opposite sides of the retention member to substantially prevent lateral movement of the locking member. The rail brace assembly also includes a resilient spring-clip fastener having a first end adapted to be inserted into the bore of the retention member and a second end adapted to engage the front surface of the locking member such that the fastener resiliently biases the rear friction surface of the locking member into interlocking engagement with the front friction surface of the brace member to thereby inhibit lateral movement of the brace member. The engagement of the top surface and of the bottom surface of the brace member with the rail inhibits transverse and rotational movement of the rail. The insertion of the toe of the brace member into the recess of the retention member enables the retention member to inhibit vertical movement of the brace member and of the rail. The retention member includes a stop member in communication with the bore to limit how far the first end of the fastener can be inserted into the bore of the retention member.

between two peaks


112


of the front friction surface


108


of the brace member


70


. Similarly, each ridge


110


and peak


112


of the front friction surface


108


of the brace member


70


is adapted to be located within a valley


142


of the rear friction surface


136


of the locking member


130


. The rear friction surface


136


of the locking member


130


thereby interlocks with the front friction surface


108


of the brace member


70


to inhibit lateral movement of the brace member


70


with respect to the locking member


130


in a direction generally parallel to the axis


78


. As shown in

FIGS. 5 and 10

, the ridges


110


of the front friction surface


108


are spaced farther apart than are the ridges


138


of the rear friction surface


136


, such that a ridge


110


of the front friction surface


108


of the brace member


70


will not be located within every valley


142


of the rear friction surface


136


of the locking member


130


.




The locking member


130


also includes a first leg


146


that extends outwardly and downwardly from the bottom end of the body


132


and a second leg


148


that extends outwardly and downwardly from the bottom end of the body


132


. The legs


146


and


148


are spaced apart and generally parallel to one another. A gap


150


is formed between the legs

and


148


. Each leg


146


and


148


includes a foot


152


that is disposed at an angle to the body


132


of the locking member


130


.




The rail brace assembly


20


also includes a retention member


160


as best shown in

FIGS. 11-14

. The retention member


160


includes a body


162


having a first side wall


164


at a first end and a second side wall


166


at a second end. The body


162


includes a base


168


which is adapted to be attached to the top surface of the tic plate


22


by welding or the like. The base


168


includes a bottom surface


170


which is adapted to be located on the top surface of the tie plate


22


. The body


162


includes a bore


172


which extends from the first side wall

174


located in the first side wall


164


and a second aperture


176


located in the second side wall


166


. The bore


172


includes a circumferential side wall


178


which is generally egg-shaped in configuration. The body


162


includes a stop member in the form of a wall


180


which projects inwardly from a portion of the side wall


178


into the bore


172


. The wall


180


includes a generally planar inner surface


182


which is generally perpendicular to the longitudinal axis of the bore


172


, and an end surface


184


which extends generally diametrically across the bore


172


. The wall


180


defines the second aperture


176


. The second aperture


176


has a smaller area than the first aperture


174


.




The retention member


160


also includes a vertical engagement member


186


having generally planar and vertical rear surface


188


. The engagement member


186


forms a recess in the form of an elongated groove


190


which extends from the first side wall


164


to the second side wall


166


. The groove


190


forms a generally planar and vertical side wall surface


192


which extends upwardly from the bottom surface


170


. The engagement member


186


includes a generally planar wall surface


194


which extends generally horizontally from the top end of the side wall surface


192


to the bottom end of the rear surface


188


. The groove


190


is adapted to receive the toe member


120


of the brace member


70


. The retention member


160


also includes an inclined front surface


196


that extends between a first raised portion


198


located adjacent the first side wall


164


and a second raised portion


200


located adjacent the second side wall


166


. The retention member


160


is preferably formed from cast steel.




The rail brace assembly


20


also includes a resilient fastener such as a spring clip member


208


as best shown in FIG.


4


. The spring clip


208


includes a first leg


210


at a first end and a second leg


212


at a second end. The legs


210


and


212


are spaced apart and generally parallel to one another. A body portion


214


extends between the first leg


210


and the second leg


212


. The spring clip


208


is formed from steel and is resiliently flexible. The first leg


210


of the spring clip


208


is adapted to be inserted into the bore


172


of the retention member


160


through the first aperture


174


. The second leg


212


of the spring clip


208


is adapted to engage the front surface


134


of the locking member


130


and to exert a resilient biasing force against the front surface


134


. The body portion


214


of the spring clip


208


is adapted to engage the inclined front surface


196


of the retention member


160


. The spring clip


208


is a commonly available commercial item.




In operation, the base


46


of the rail


24


is located on the bottom wall


28


of the rail seat


26


such that the flange


50


is in abutting engagement with the side wall


34


of the rail seat


26


. The retention member


160


is attached to the top surface of the tie plate


22


such that the side wall surface


192


of the groove


190


is generally parallel to the angled side wall


36


of the rail seat


26


and is thereby disposed at a horizontal angle to the longitudinal axis


78


of the brace member


70


and to the longitudinal axis


64


of the rail


24


. The side wall surface


192


of the groove


190


is preferably generally coplanar with the angled side wall


36


, or spaced slightly inwardly from the angled side wall


36


of the rail seat


26


.




The brace member


70


is placed in engagement with the rail


24


such that the lower surfaces


84


and


94


are in engagement with the base fishing surface


52


of the rail


24


, and such that the upper surfaces


86


,


96


and


104


are in engagement with the head fishing surface


62


of the rail


24


. The toe member


120


of the brace member


70


is located in the rail seat


26


between the outer end of the first flange


48


of the rail


24


and the angled side wall


36


of the rail seat


26


, and within the recess


190


of the retention member


160


. The brace member


70


is moved laterally in a direction generally parallel to the longitudinal axis


78


, and generally parallel to the central axis


64


of the rail


24


, until the front engagement surface


124


of the toe member


120


matingly engages the side wall surface


192


of the groove


190


in the retention member


160


and the angled side wall


36


of the rail seat


26


. The brace member


70


is then forcefully moved by a sledge hammer, hydraulic cylinder or the like further in a lateral direction toward the second edge


32


of the rail seat


26


, such that the brace member


70


is wedged between the retention member


160


and the rail


24


with the toe member


120


being wedged within the groove


190


of the retention member


160


. The concave surface portions


90


of the ribs


80


and


82


of the brace member


70


provide a large gap with the rail


24


to allow for the positioning of a switch heater rod against the rail


24


.




The locking member


130


is then located in position such that the body


162


of the retention member


160


is located within the gap


150


and between the legs


146


and


148


of the locking member


130


, such that the first leg


146


is located adjacent the first side wall


164


of the retention member


160


and such that the second leg


148


is located adjacent the second side wall


166


of the retention member


160


. The rear friction surface


136


of the locking member


130


is placed in interlocking engagement with the front friction surface


108


of the brace member


70


such that the ridges


110


of the front friction surface


108


of the brace member


70


are each located within a valley


142


in the rear friction surface


136


of the locking member


130


. The ends of the legs


146


and


148


of the locking member


130


engage the upper engagement surface


126


of the toe member


120


of the brace member


70


.




The first leg


210


of the spring clip


208


is then inserted into the bore


172


of the retention member


160


through the first aperture


174


. The first leg


210


is inserted until the end of the first leg


210


engages the inner surface


182


of the stop wall


180


. The stop wall


180


thereby prevents the first leg


210


of the spring clip


208


from being inserted into the bore


172


beyond a predetermined distance. The body portion


214


of the spring clip


208


engages the inclined front surface


196


of the retention member


160


, and the second leg


212


of the spring clip


208


is in biased engagement with the front surface


134


of the locking member


130


. The second leg


212


of the spring clip


208


thereby resiliently biases the rear friction surface


136


of the locking member


130


into interlocking engagement with the front friction surface


108


of the brace member


70


. The spring clip


208


can be selectively removed from the retention member


160


to disassemble the locking member


130


and brace member


70


. The stop wall


180


of the retention member


160


prevents the first leg


210


of the spring clip


208


from being over inserted into the bore


172


of the retention member


160


. Over insertion of the spring clip


208


into the bore of a retention member


160


can cause the spring clip


208


to eventually fail from fatigue.




As the legs


146


and


148


of the locking member


130


straddle the retention member


160


, the legs


146


and


148


prevent lateral movement of the locking member


130


with respect to the retention member


160


. The biased interlocking engagement between the rear friction surface


136


of the locking member


130


and the front friction surface


108


of the brace member


70


inhibits lateral movement of the brace member


70


, in a direction generally parallel to the axes


64


and


78


, with respect to the locking member


130


and thereby with respect to the retention member


160


and the rail


24


. The second leg


212


of the spring clip


208


applies a resilient biasing force to the locking member


130


and thereby to the brace member


70


which biases the lower surfaces


84


and


94


into engagement with the base fishing surface


52


of the rail


24


, and which biases the upper surfaces


86


,


96


and


104


into engagement with the head fishing surface


62


of the rail


24


. As the front friction surface


108


of the brace member


70


is disposed at a vertical angle of forty-five degrees or greater to horizontal, the biasing force applied by the spring clip


208


to the brace member


70
