Abstract
An automatic coupler of the Janney-type has a guide horn rigidly connected to the coupling head below the knuckle and extends forwardly and laterally with respect to the knuckle. The guide horn is shaped to have on its upper face a plurality of guide and support surfaces. A second plurality of guide and support surfaces are formed on the underside of the rigid catch jaw which is spaced horizontally from the pivotable knuckle. The guide surfaces on the guide horn and underside of the jaw engage respectively guide surfaces on the underside of the jaw and a guide horn of a similar coupler when such couplers are in the coupled position so as to prevent relative vertical displacement of the coupled coupling heads.
Claims5
An automatic coupler for railway vehicles comprising a coupling head having a rigid catch jaw and a knuckle pivotable about a vertical axis spaced horizontally from said jaw to define a coupling mouth therebetween, said knuckle being pivotable outwardly in a coupling position and pivotable 90.degree. inwardly into a coupled position, latch means for locking said knuckle in its coupled position, a guide horn rigidly connected to said coupling head below said knuckle and extending forwardly and laterally outwardly with respect to said knuckle, said guide horn having a plurality of guide and support surfaces thereon, there being a second plurality of guide and support surfaces on the underside of said catch jaw, said first and second pluralities of guide and support surfaces engaging resqectively second and first pluralities of guide and support surfaces of a similar coupler in the coupled state to prevent relative vertical displacement of the coupled coupling heads, and a projection from said coupling head spaced below said jaw and having a horizontal top surface, said projection having a plurality of progressively sloping surfaces from the forward portion of the projection to the top surface thereof, said projection being engageable with the underside of a guide horn of a similar coupler in the coupled position.
