Abstract
A railway coupler arrangement which eliminates the conventional yoke strap, thereby enabling a larger draft gear to be employed in the coupling without increasing the overall size of the sill. The invention also provides a novel assembly for facilitating a rotary coupler arrangement in which the diameter of the rotary shank can be increased over prior art rotary butt couplers.
Claims5
A railway coupler arrangement comprising a center sill, front and rear draft lugs within the sill, a draft gear housing having forward and aft wall means, said draft gear housing being carried within the sill and slideable between the front and rear draft lugs, a draft gear within the draft gear housing, a follower and plunger block slideable in said draft gear housing and in engagment with one end of the draft gear, a coupler yoke shank extending into said draft gear housing, a butt on said shank engageable with said follower and plunger block within the draft gear housing and movable from a position where it engages said forward wall means on the draft gear housing during draft loads to a position removed from the forward wall means where it forces the follower and plunger block into the draft gear during buff loads, the aft wall means of the draft gear housing engaging said rear draft lugs during buff loads, and means associated with said front draft lugs for engaging said follower and plunger block during draft loads to compress said draft gear.
