Abstract
Horizontally top-hinged side-swinging doors on a railway truck are operated by a mechanism comprising longitudinal shafts C carrying latches E and door lifters B, rods F pivoted to levers D on the shafts, rods I pivoted to supports N and to the rods F, compression springs J acting on the rods I, and a pivoted beam G which may engage a ramp L beneath the truck to move the mechanism to the door open position of Fig. 3. To open the doors the extra latches A, Fig. 2, are first pivoted to inoperative position. The truck is then run over the ramp L so that the beam G assisted by the springs J pivots the jointed rods F and I over their dead points to cause the lifters B to pivot away from the doors which swing open under the thrust of the load. Projections K on the rods 1 may be hand operated by extension levers, Fig. 5 (not shown) when manual discharge is required.
