Abstract: A gasket and retainer arrangement for use in a coupling of the type having first and second coupling components with opposed end faces including sealing ribs extending axially therefrom with an annular sealing gasket interposed therebetween comprises a retainer device for maintaining the gasket in a predetermined located position relative to the end face of one of the components. The retainer includes a generally sleeve-like body defining a retaining portion closely received over the one component at an area rearwardly from the associated radial end face. A plurality of axially extending leg portions are spaced about the retaining portion and extend axially beyond the associated end face. The annular sealing gasket has an outer periphery of a diameter at least slightly greater than the inner diameter of the sleeve-like body with recesses formed in the outer periphery to receive the axially extending leg portions whereby the gasket is maintained in aligned relationship with the end face.

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.
