Abstract
A railway car underframe comprises a center sill having bell mouth draft housings at opposite ends thereof. The housings accommodate the use of drawbars or shank type couplers. With the use of a shank type coupler a draft housing extension is secured to the bell mouth housings. The housings include structural shear elements interengageable with each other to align and secure the housings in rigid relation. The housings include connector plates secured together by fasteners with said connector plates longitudinally spaced apart to provide vertical spaces. Wedge elements having open end vertically spaced recesses are driven into the vertical spaces to provide for rigid metal to metal contact with the spaces accommodating the fasteners. Proper alignment, securement, and quick assembly therefore is achieved.
