TRIPPING DRIVE OF RAILROAD TRANSPORT MEAN AUTOMATIC COUPLING Russian patent published in 1994 - IPC

FIELD: transport engineering. SUBSTANCE: lever 1, besides handle and tripping arm 2 with chain, has third blocking arm 3, directed in opposite side from tripping arm and connected with lower part of balancer of lifter 7 roller by blocking chain 6. So, in case of automatic coupling break and following vans going away both chains - tripping and blocking are pulled simultaneously and turn of lifter roller and consequent tripping of automatic couplings do not take place, that, due to presence of vertical motions limiter, prevents automatic coupling dropping down. EFFECT: tripping drive of automatic coupling is used by railroad transport means. 2 dwg
