ABSTRACT:
A draft gear is described as having rubber cushion pads and a friction clutch with a wedge and two friction shoes. The housing of the draft gear is provided with strategically located openings through which bars can be passed to neutralize the spring force of the cushion pads and facilitate assembly and disassembly of the draft gear. Further, an extra spring is provided to continuously load the wedge shoes to maintain them in frictional engagement with the wedge.
