Abstract: A specially configured insert used in a drawbar support housing. The insert is essentially a block member having at least a portion of an aperture extending therethrough from a front face to a back face. A concave draft load bearing surface is formed in the front face of the block member adjacent such aperture. A tapered surface area is formed adjacent such aperture which extends from the back face of the block member inwardly towards the concave draft load bearing surface to enable requisite movement of a shank portion of a drawbar.

Abstract: A support housing for a rotary end of a slackless drawbar adapted to be secured within an end of a center sill of a railroad car having an elongated cavity defined by a pair of side wall portions, a top wall portion and a back wall portion, said cavity being adapted to receive the rotary end portion of a rotary drawbar such that a shank portion of such rotary drawbar extends through an open front of the support housing, said cavity being further adapted to receive a buff load bearing block and a slack adjusting gravity wedge between the back wall portion and the rotary end of the rotary drawbar and having a specially configured surface therein adapted to receive a specially configured draft load bearing insert and a flange to retain the specially configured draft load bearing insert within the cavity and against the spherical draft load bearing surface on the rotary end of the rotary drawbar.

Abstract: An integral yoke member casting having a back wall portion, a first side wall portion formed integral with the back wall portion adjacent a first outer edge thereof. The first side wall portion has a front face portion which is engageable with a rear face portion of a front stop secured within a center sill member. A second side wall portion is formed integral with the back wall portion adjacent a second outer edge thereof. The second side wall portion includes a front face portion which is engageable with a rear face of another front stop secured within such center sill member. A top wall portion extends between inner surfaces of the first and second side wall portions and outwardly from such rear wall portion past the front faces of both the first and second side wall portions. There is a bottom wall portion which extends between such inner surfaces of such first and second side wall portions and outwardly from such rear wall portion past the front faces of both the first and second side wall portions.

Abstract: An integral single piece yoke casting for connecting one end of a railway car. Such single piece yoke casting includes a first side wall portion having a front face portion which engages at least a portion of a rear face of a front stop member secured within a longitudinal opening of a center sill member. A second side wall portion having a front face portion engages at least a portion of a rear face of another front stop member secured within such longitudinal opening of such center sill member. A horizontally disposed top wall portion, having a third predetermined length and a horizontally disposed bottom wall portion, having a fourth predetermined length, in conjunction with the first side wall portion and the second side wall portion form a generally rectangular yoke casting.

Abstract: A drawbar assembly having a rear draft stop engageable with a block out member. A tapered wedge member engages a tapered surface on the block out member. A follower member engages a front face of the tapered wedge. A concave surface is formed in a front face portion of the follower member. Such follower member is movable within the open end of a yoke casting. Such yoke casting includes first and second side walls, a top wall and a bottom wall. A first and second aperture are formed through the top wall and bottom wall, respectively. A pair of front draft stop members engage a respective side wall of such center sill. A drawbar having a butt end portion is movably disposed within a second opening in such yoke casting. Such drawbar includes a vertically disposed pin receiving opening formed in such butt end and a two piece pin bearing block having a hemispherical outer surface is disposed in a hemispherical recess formed in such pin receiving opening.

Abstract: A draft stop member in a car coupling arrangement includes a rectangular block-like member. An arcuate portion extends forward from the rear face and inward from the stop upper surface and terminates before a longitudinal centerline thereof. Another arcuate portion extends forward from the rear face and inward from the stop bottom surface and terminates before such centerline. A triangular block-like member formed integral with an inner portion of the rectangular member includes another arcuate portion beginning inward from the stop upper surface and terminating before the centerline. Another arcuate portion begins inward from the stop bottom surface and terminates before the centerline. A nose member formed integral with an inner portion of the triangular member includes an arcuately shaped end disposed axially opposed to the rear face of the rectangular member. A tapered upper surface extends inward toward such rear face from one end of the arcuately shaped end and upward from the centerline.

Abstract: A drawbar bearing block for a slackless drawbar system which connects adjacent ends of a pair of railway cars in a semi-permanent manner. Such bearing block includes a top portion supported and retained in a hemispherical recess which extends partially around a pin opening formed in a pin receiving opening disposed in a butt end of a drawbar. Such top portion of the bearing block has an outer surface which closely matches a surface of such hemispherical recess and an inner surface having a cylindrical shape to receive a pin therein. There is at least one recessed opening formed in the top portion adjacent a bottom surface and an outer surface thereof. A bottom portion is supported and retained in such hemispherical recess and assists in supporting and retaining such top portion in the hemispherical recess. Such bottom portion of the bearing block includes an outer surface which closely matches the surface of such hemispherical recess and an inner surface having a cylindrical shape to receive a pin therein.

Abstract: 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.

Abstract: A railway car yoke having a rear end portion, a body portion, a top forward portion and a bottom forward portion. Each of the top forward portion and the bottom forward portion include a thickened portion through which one aperture is formed to receive a connecting pin therein. A bottom strap portion of such body portion includes an aperture therein to enable adjustment of a blockout device contained within such yoke.
