A trip 9ilis hinged at 1 O.to a cross bar 11 of. the trap framel; The trip, .9 consists of v parallel, members which are curved toward thecarv-3, as indicated in Fig. 4:, and are spaced apart for suitably; arranged space I bars 12.,

Recoil 1 springs 18 are-riveted to the ends of-the trip members 9 ,-and the recoil springs are curled at their free ends and adapted to. engage one ofa plurality of lorace bars-14c of the trap. framed as shown in Figs. 3 and 41.1 .A t ipbar ldis pivoted at one end to ears 16 secured to one of the bars 12 ofithe trip 9 The other endof thetriphar-15 is v piyotedfto the fulcrum stud 17 of an arm 18 loosely mounted onthe framesupport 5;

The, operationiofjthe device is as folloyvs The. trap frame 1 is {set to the position indifate! a ree-flee lig" t. were mail bag M. The trip 9 is pulled out to bridge the space between. the throat piece 4:

and the car 8. In pulling the trip '9 out, the trip bar 15 also pulls upon the fulcrum stud 17 and moves it in advance of a line drawn between the pivotalpointand the links 19 Y on the stud 20 and the frame support 5, in

which position, the linksQO- and the arms 18 toward the bag which enters the throato-f the device and strikes the trip' 9. v The im pact of the bag against the trip 9, causes the links 19' and "arm 18 which are braced against each other, to-collapse, whereupon the leaf springs 23- quickly thrust the trap frame 1 toward the side of the car 3 and throw the mail ba M through the doorway 2 into the car.

The operation of catching the mail bag M is entirely automatic. The trap frame 1 is panyingdrawings'are'those of agenera1ly' preferred form, obviously modifications and 7 changes may be 'made Without departing invention orthe scope set to the position indicated in dotted lines 1n. F1g. 4c, and no further attention need be] paid to the device. The car and theca'tching device in advancing toward the mail bag M, receive the bag in the throatformed between the trap 1 and the side of the car, where the trip 9 which holds the trap frame 1 away from the car, is struck and causes the collapse of the link members that hold the trap'frame open. The trip bar 15 pulls the trip 9 back to the position indicated in full lines in Fig. 1, after the trap frame 1 has moved inwardly toward the car.
