Abstract
An improved attaching device is provided for securely mounting railroad signalling and monitoring equipment (10, 12) on the coupler (36) of a railroad car. A package including a supporting frame (22) to which the equipment is fastened by a draw pull (16) rests on the top surface of the coupler. The supporting frame includes a mounting bracket (32) having an integral rod (50) which extends through the flag hole in the coupler knuckle. The end of the rod projects beyond the bottom of the coupler so that it can be secured. In the second embodiment (FIGS. 8 and 9), the rod (111) has bifurcated extensions (116, 118) which serve to strengthen the supporting frame (80). This embodiment also includes shock absorbing elements (108, 110 and 122). In a third embodiment, a post (162) slidably carries a shaft or rod (188) that is retractable into a locking position with the coupler. A crank (176) is used to retract the shaft into a locking position. The crank carries a locking bar (234) which cooperates with locking members (230, 232) on the equipment package to secure the package in place. The three embodiments all feature top of coupler mounting in such manner that the railroad signalling and…
