SLACKLESS DRAWBAR ASSEMBLY EMPLOYING ADJUSTABLE BLOCKOUT APPARATUS ABSTRACT OF THE DISCLOSURE There is provided a slackless drawbar assembly which connects the adjacent ends of a pair of railway cars together in a substantially semi-permanent fashion. The assembly includes a yoke, an adjustable blockout apparatus which has a pair of spaced end blocks and an adjustable securing device which comprises a pair of spaced wedge members. There are outwardly extending flanges on the confronting end faces of the end blocks which engage tongues or tenons on the end walls of the spaced wedge members. The adjustable securing device comprises coaxial bores through the spaced wedge members and a threaded member extending between and through the coaxial bores and threadably engaged with threads formed in at least one of the bores such that upon rotating the threaded member in one direction, the spaced wedge members will be moved together, to push the pair of end blocks apart, while upon rotating the threaded member in the other direction, the spaced wedge members will be moved apart to pull together the pair of spaced end blocks. A preferred yoke includes a rear end portion which has a front face that forms a rear seat for a blockout device. There are a top strap portion and a bottom strap portion extending forwardly of the front face of such rear end portion of the yoke. Each of such top and bottom strap portions includes a thickened portion, at its end remote from such rear end portion of the yoke, which has a bore therethrough to receive an end of a drawbar connecting pin to connect the yoke to a drawbar.
