Abstract

A bifurcated mounting bracket for a caboose replacement signal transmitting unit straddles the coupling knuckle of a rear train car and is secured to the knuckle by a lower end pivoted hasp which is padlocked to the bracket. Depending and upstanding teeth on the bracket and hasp, respectively, positively engage top and bottom surfaces of the coupling knuckle with minimized metal-to-metal contact. The signal transmitting unit is supported above the elevation of coupling crowns to avoid destruction. The mounting allows the coupling of another car in the train behind the car on which the signal transmitting unit is mounted without destruction of the unit or its mounting.

Claims

1. A mounting for a caboose replacement signal transmitting unit comprising a bifurcated mounting bracket having spaced substantially parallel leg portions adapted to straddle the knuckle of a rail car coupling in a front-to-back plane and having a top wall interconnecting said leg portions above the top of the knuckle, releasable means on the mounting bracket and extending near and across the bottom of said knuckle to lock the bifurcated bracket to the knuckle, depending and upstanding stabilizing teeth on said top wall and said releasable means respectively adapted to engage top and bottom surfaces of the knuckle when the releasable means is in a substantially horizontal position locking the bracket to the knuckle, and an extension on the mounting bracket at its top of sufficient length to support a caboose replacement signal transmitting unit at an elevation above the top of a rail car coupling crown.

2. A mounting for a caboose replacement signal transmitting unit as defined in claim 1, and said releasable means comprising a pivoted hasp plate on the lower end of one straddling leg portion and adapted to be padlocked to the other leg portion of the mounting bracket across the bottom of said knuckle so that the bracket is arranged in completely surrounding relationship to the knuckle.

3. A mounting for a caboose replacement signal transmitting unit as defined in claim 2, and the hasp plate having an aperture near its free end adapted to receive therethrough a lower end extension of said other leg portion, and said lower end extension having a padlock shackle receiving aperture below the hasp plate.

4. A mounting for a caboose replacement signal transmitting unit as defined in claim 2, and said teeth being provided in spaced pairs on said top wall and hasp plate near opposite sides of the top wall and hasp plate, the teeth of the pairs near one side being longer than the teeth in the pairs near the opposite side, and the teeth on the top wall being downwardly tapered and the teeth on the hasp plate being upwardly tapered to minimize contact areas of the teeth with said knuckle.

5. A mounting for a caboose replacement signal transmitting unit as defined in claim 4, and said top wall and hasp plate being substantially trapezoidal and tapering forwardly with relation to the knuckle, said teeth in said pairs being forwardly convergent along edges of the top wall and hasp plate, and the rearwardmost of said straddling leg portions being substantially wider than the forward leg portion of the bifurcated mounting bracket.

6. A mounting for a caboose replacement signal transmitting unit as defined in claim 1 and said teeth being provided in spaced pairs on said top wall and releasable means near opposite sides of the top wall and releasable means.

7. A mounting for a caboose replacement signal transmitting unit as defined in claim 6 and said teeth in said pairs being forwardly convergent on said top wall and on said releasable means.

8. A mounting for a caboose replacement signal transmitting unit as defined in claim 1 and the rearwardmost of said parallel straddling leg portions being substantially wider than the forward leg portion of the bifurcated mounting bracket.

9. A device for mounting a caboose replacement signal transmitting unit on the knuckle of a railway car coupling comprising a bifurcated bracket having spaced substantially parallel legs adapted to straddle a coupling knuckle and a leg connecting top portion adapted to rest on a coupling knuckle supportingly, releasable locking means for the bifurcated bracket resisting upward displacement of the bracket when engaged with a coupling knuckle, depending and upstanding stabilizing teeth on said leg connecting top portion and said releasable locking means respectively adapted to engage top and bottom surfaces of the knuckle when the releasable locking means is in position to resist upward displacement of the bracket, a caboose replacement signal transmitting unit, and an extension support member rising from the top of the bracket and adapted to be connected with and to support a caboose replacement signal transmitting unit at a sufficient elevation above a coupling knuckle to avoid collision of the unit with the crown of another railway car coupling.

10. A device for mounting a caboose replacement signal transmitting unit as defined in claim 9, and said releasable locking means comprising a hinged hasp plate on the lower end of said bracket adapted to be locked in a substantially horizontal position across the bottom of a coupling knuckle while extending between said legs.

11. A device for mounting a caboose replacement signal transmitting unit as defined in claim 10, and the hasp plate being apertured to receive therethrough one leg of the bracket when the hasp plate is in its locked position, said one leg being apertured below the hasp plate, and a locking element engageable through the aperture of said one leg.

12. In a device for use with the knuckle component of a railway car coupling having a rear outer curved wall and a foward inner curved wall, the combination with the knuckle component of connector means having portions adapted to respectively engage the rear outer curved wall and forward inner curved wall of the knuckle, releasable locking means connected transversely between said portions to prevent removal of said connector means when engaged with the knuckle, a housing, and means connecting said housing to said connector means at an elevation above said portions which engage the walls of the knuckle.

13. The combination as defined in claim 12, in which said portions comprise a rear comparatively wide vertical leg portion for engagement with the rear outer curved wall of the knuckle, and a forward relatively narrow vertical leg portion for engagement with the inner curved wall of the knuckle.

14. The combination as defined in claim 13, and non-metallic elements on the opposing interior faces of said leg portions adapted to engage the forward inner curved wall and rear outer curved wall of said knuckle to avoid metal-to-metal contact of said connector means with said knuckle.

15. The combination as defined in claim 13, and said connector means including a wall portion interconnecting said rear leg portion and said forward leg portion on the end opposite said releasable locking means.

16. The combination as defined in claim 13, and said releasable locking means comprising a hasp plate hingedly connected on one end of said rear leg portion and adapted to be locked in a substantially horizontal position across a substantially horizontal surface of the knuckle while extending between said rear and forward leg portions.
