Abstract: A railroad car coupling mechanism is described as having a yoke which is disposed within, I) a carsill which is attached to the underside of a railroad car adjacent each of the opposing ends of the car, and II) a striker which is secured to the subsill and railroad car. The striker and carsill carry front and rear stops between which the yoke extends and engages the front stops. At least one resilient load cushing device is disposed between the straps of the yoke for cushioning loads impacting the car coupling mechanism. At least one wedging device is disposed within the yoke straps, in tandem, with the load cushioning device, for taking up any slack which develops from worn parts within the yoke. At least one wedging mechanism is disposed outside the yoke between the back end of the yoke and the rear stops to, likewise, take up slack and insure that the yoke remains firmly, in place, between the front and rear stops.
Abstract: A coupler yoke for a coupler of a railway vehicle is constructed with a nose portion which is reinforced by a raised region which surrounds the forward end of the key slot. A tapered buttress extends along the length of both sides of the key slot. The width and depth of the buttress increase from minima at the rearward end of the key slot, and merge with the raised region reinforcing the nose of the yoke.
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.

The sliding yoke having a front pocket portion open at a front end thereof. The front pocket portion is formed by a top wall portion, a bottom wall portion and a pair of radially opposed side wall portions which form a continuous outer wall. Such continuous outer wall has an outer cross section complementary to an interior cross section of such center sill and capable of both being received therein and sliding longitudinally thereof. The top wall portion has a first bore therethrough and the bottom wall portion has a second bore therethrough concentric with such first bore. A rear block portion having a top wall portion, a bottom wall portion and side wall portions each adjacent the corresponding top wall portion, bottom wall portion and side wall portions of such front pocket portion.
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.

Abstract: A slackless drawbar system for a railway car in which there is provided an elastomeric pad that absorbs forces during buffing conditions and helps to maintain the slackless nature of the system. The elastomeric pad absorbs forces during lateral and vertical angling and serves to maintain the slackless nature of the system during these conditions. Preloading of the resilient elastomeric pad is provided by means of an adjustable wedge element, which wedge element is adjustably positionable relative to the elastomeric pad by means of a screw shaft and nut, whereby the initial loading of the pad may be achieved to meet any required operating conditions and to accommodate wear and tear.
Abstract: A yoke for a railway car coupler assembly includes a yoke body having a generally rectangular front portion. A central opening provided in the front portion extends longitudinally therethrough. A pair of opposed first and second straps extend rearwardly from the front portion and are connected by a bridge portion. The side walls of the front portion are tapered inwardly toward the bridge portion to accommodate a striker having thickened side walls. Also, recessed portions are provided in the yoke central opening to accommodate the shank of a strengthened coupler. A bearing pad provided on the yoke bridge portion has relieved areas to prolong the service life of the yoke.
Abstract: A rotary railroad car F. coupler assembly which employs a rotary connector between the yoke and car coupler, is described as having a yoke with a larger diameter opening in which a bigger rotary connector is mounted. The rotary connector in turn, is designed to receive an AAR standard F coupler head with a heavier shank that has sidewalls, bordering the pinhole in the shank, which are thicker and have greater cross-sectional areas than similar sidewalls of shanks of AAR standard non-rotary type F car couplers.
Abstract: A rotary railroad car F coupler assembly which employs a rotary connector between the yoke and car coupler, is described as having a yoke with a larger diameter opening in which a bigger rotary connector is mounted. The rotary connector, in turn, is designed to receive an AAR standard F coupler head with a heavier shank that has sidewalls, bordering the pinhole in the shank, which are thicker and have greater cross-sectional areas than similar sidewalls of shanks of AAR standard non-rotary type F car couplers. A pair of twin, parallel wearplates are provided between the top of the yoke and the adjacent housing. The top ridged portion of the yoke extends between these wearplates. In this way, the diameter of the yoke opening and the consequent cross-sectional area of the opening are increased. This enables a larger, sturdier coupler shank to be received in the aperture of the yoke while the overall coupler assembly may still be mounted in an AAR standard carsill.
Abstract: A rotary railroad car coupler and attached draft gear are provided with strategically located stops for maintaining a predetermined clearance between the butt end of the shank of the coupler and the adjacent front follower of the draft gear when the coupler is in a neutral position intermediate the buff and pull positions, whereby an operator can readily mount the coupler to the yoke of the draft gear, especially in a side entry pivot pin arrangement where it becomes necessary to rotate the car coupler.
Abstract: An improved rotary-type F Car Coupler. The yoke of the coupler is provided with the side opening through which the pin for holding the shank of the coupler head to the yoke is removed. A plate is provided for covering the side opening and retaining the pin in position between the shank and yoke. The retainer plate is rotated into interlocking engagement with the yoke, and a cotter pin and stop are provided for restricting rotation of the plate to maintain it in interlock relation with the yoke.
Abstract: A rotary type railway car coupler is provided wherein the shank and yoke collar can be assembled only in the proper orientation with respect to one another. Either the shank or yoke collar is provided with a projection and the other is provided with a corresponding groove.

Abstract: The invention relates to a rapid transit draft rigging for an automatic coupler which includes a yoke, disposed within a drawbar, which has a stem abutment extending inwardly from the rear of the yoke, passing through a shear block release member and contacting the rear surface of a follower block which is adjacent a cushioning member.
Abstract: The keyslot of a railway coupler shank is modified to eliminate the interference between the coupler shank and draft key during conditions of buff or draft during vertical curve negotiation of the cars when traversing uneven track. The upper and lower walls of the keyslot diverge from the rear bearing surface of the keyslot adjacent the butt of the coupler shank. Thus the keyslot opening is wider in the front portion than at the rear portion.
