purpose of adapting tlieplate to curved rails.

In order to actuate the trip plates successively, the locomotive or'car is equipppd ie to permitthelianger to freely swing over the plates without pressure when the train is backing but prevents swinging thereof as the train approaches the crossing in order that the trip plateswill be successively actuated;

Asshown in Figures 1 and 2, the plate 31 is in position to permit the roller to gradually press upon the web 32 and as the roller travels forward it rides upon the web 33, thus causing the plate to turn and, since the shaft 30 turns, the cable 38 wlllbe pulled to 'actuate thelever 25 to swin 'the gate bars 21 and 22 downwardly to serve as a barrier, and as this occurs, the web 11 of the plate 8 s elevated. As the train approaches the plate 8 theroller engages the web 10, and upon further movement of the roller, the plate is rotated, and as the roller passes from the 'web 11 the shaft 7 will be actuated, thus actuating the bell crank 17 and the lever 25 As the bars swing upwardly, the cable will be pulled to again elevate the web 33 of the plate 31,

at which time the web 32 will be lowered,

thus resettingthe device for the next train.

. What is claimed is:

1. The combination with a railway gate bar, of a'pair of trip plates mounted adjacent the track, said plates comprising angu larly' disposed webs, shafts fixed to the webs,

connections between the shafts and gate bar for raising and lowering the same when the webs are successively actuated, and means carried by a tram passing over the track for actuating said webs.

2. The combination with a railway gate,

of a pair of trip plates mounted adjacent the track, said plates. comprising angularly dis-,

and gate, a cable connecting said connection and end of the other shaft, and means carried by a train passing over the track for successively encountering the webs for rocking the same to actuate the cable to raise and lower-the gate.

4; The combination with a railway gate,

of apair of trip plates mounted adjacent the p track and including angularly disposed webs, shafts fixed to the webs, means carried by the train passing over the track to engage the webs to successively rotate the same to raise and lower the gate, and means connecting the shafts of the respective plates successively changing the angular relationship of the webs.

5. The combination with a'railway gate, of a pair of trip plates mounted adjacent the track and including angularly disposed webs, connections between each plate and gate, and means carried by the train passing over the track for engaging the webs to suecessively rotate the same to operate the connections to lower thegate when said means encounters one of the plates and to raise the gate when encountering the other plate.

6. The combination with a railway-gate,

of trip plates mounted adjacent the track, I

said plates comprising angularly' disposed webs, shafts fixed to the plates, a bell crank lever pivotally connected with the shaft of each plate, operating means between one bell crank and gate, a cable connecting the bell cranks, and means carried by a train passing over the track for successively engaging the webs to successively operate the bell crank levers to first lower the gate and then raise the same. 7

In testimony whereof we alliX our signatures.
