DRAFT-RIGGING FOR RAILWAY-CARS.

Patented May 11, 1920.

Application filed August 28, 1919. Serial No. 320,453.

To all whom it may concern Be it known that I, WiLLmM J. REGAN, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Draft-Rigging forRailway-Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to draft rigging for railway cars and is especially directed to the production of simple, strong, durable and efiicient means for securely connecting a car coupler and draft yoke in a manner enabling them to be readily attached or disconnected. Generally stated, this object is accomplished by providing the coupler at the rear end of its shank with oppositely extending projections, and by constructing the forward end of the yoke with a socket portion or hood having afixed shoulder or stop and a movable shoulder or stop, the said stops or shoulders being adapted to stand in front of the corresponding projections on the coupler shank to thereby connect the coupler to the yoke, and the said socket portion also being provided with vertically spaced inseparable faces adapted to embrace the rear end of the coupler shank and to maintain it in proper relation to the yoke, thereby preventing the movable stop from being subjected to any unusual strains.

In the drawings illustrating the preferred form of my invention, the scope whereof is pointed out in the claims,

Figure 1 is a plan view of a coupler and yoke showing a form of my invention, the head of the coupler being omitted.

Fig. 2 is a view, partly in elevation and partly in vertical section, of the construction shown in Fig. 1, a portion of the car framing and the carrier iron for the coupler being also shown. r

Fig. 8 is a section on the line 3-3, Fig. 2.

Fig. 1 is a section on the line 4-4, Fig. 2. Fig. 5 is a view corresponding to Fig. 2, but illustrating the position of the coupler when assembling it with or disconnecting it from the yoke.

In the drawings, 1 indicates the car 0011;

pler and 2 is the draft yoke. The head of the car coupler (not shown) may be of any well-known or desired construction. At the rear end of its shank 3 the coupler is provided with oppositely disposed vertically extending projections, f and 5 respectively, which are preferably fashioned as cylindrical trunnions integrally connected to the Shank 3. The upper projection or trunnion 4% is of somewhat greater height at the front than at the rear, its upper face being sloped downwardly toward the rear as indicated at 6. As shown in the drawings the inclined or sloping face 6 is preferably curved, the center of curvature being substantially at the point of junction 7 of the coupler shank 23 and forward face of the lower trunnion 5 The lower projection or trunnion 5 is of reduced size at its lower or outer end, its rear face being beveled downwardly and forwardly as indicated at 8. The inclined orsloping face 8 is preferably curved concentrically with the sloping surface 6 of the upper projection 4. j v

The forward end of the draft yoke 2 is provided with a socket or hoodedportion 9 adapted to receive the rear end of the shank of the coupler. \Vhen, as shown in the drawings, the projections 4 and 5 are formed as pivot lugs or trunnions, the side walls 10 of the hood preferably diverge forwardly so as to impart to the socket a fiaring form permitting the coupler to swing laterally with respect to the yoke 2. The socket into which the rear end of the coupler extends is preferably separated from the yoke opening 11 for receiving the springs and followers or other cushioning unit (not shown) by a transverse wall 12 which connects the side walls 10 and also the upper and lower arms, 13 and 14 respec-, tively, of the yoke. The top wall 15 and the bottom wall 16 of the hooded portion 9 of the yoke are rigidly connected by the side walls 10 and also by the transverse wall 12 when such is employed.

7 Upon its interior the socket portion ofthe yoke 2 is provided with a face or shoulder 17 which is preferably sloped or curved to conform to the sloping face 6 of the upper projection or trunnion 4: of the coupler. lVhen the coupler and yoke are in assembled relation thetrunnions at the rear end of the coupler extend between the shoulder 17 and the interior face of the lower wall 16 offt he yoke, vertical movement of the rear end of the coupler thus being restrained.

lib

In advance of the lower projection 5 the yoke is preferably provided with a lug or shoulder 18 whose inner face conforms to and is adapted to engage the forward face of the said projection 5. lVhen, as shown in Fig. 5, the coupler 1 is being assembled, with the yoke 2 or is being disconnected therefrom it is supported and swings upon the upper, preferably sloping or rounded, surface 19 of the lug 18. In connecting or disconnecting the coupler to the yoke the carrier iron 20 which normally is attached to the car framing will be disconnected to permit of swinging the coupler vertically as may be required.

Cooperating with the fixed lug or shoulder 18 in performing the function of connecting the coupler to the yoke is a movable block or shoulder 21 which preferably is slidably mounted on the hooded portion of the yoke.

so as to be movable toward and from the lug 18 through an opening 22 in the upper wall 15 of said hooded portion. This movable member 21, which stands behind laterally spaced inwardly extending lugs 23 on the yoke, is adapted to engage the forward face of the upper trunnion at on the rear end of the coupler to thereby transmit draft strains from the said trunnion to the draft yoke 2. If desired the movable block 21 may be slotted to receive a slidable gravity actuated bar 24 which is adapted to move under a portion of the upper wall 15 of the yoke and thus lock the block 21 against accidental displacement from its assembled position.

The upper wall 15 of the hooded portion of the yoke 2 preferably extends forwardly beyond the lower wall 16 thereof. This construction is advantageous in that it not only 7 permits the movable blockor shoulder 21 to be made of great strength and to be strongly supported against draft strains,

communicated to it by the coupler, but also allows the point about which the coupler turns when. being assembled with the yoke or disconnected therefrom to be located well toward the rear end of the coupler, thus minimizing the vertical swinging movement of the rear end of the coupler and thereby reducing theheight of the forward end of a coupler and draft yoke, said members being provided with means for detachably connecting them to each other, and said means involving vertically spaced inseparable faces on said yoke adapted to engage said coupler and between which said coupler is interposed and separable shoulders carried by said yoke and adapted to prevent forward longitudinal movement of said coupler with respect to said yoke, one of said separable shoulders being stationary and the other movable into and out of position in front of a projection on the rear end of the coupler shank when the yoke and coupler are in assembled relation.

2. In a draft rigging, the combination of a coupler and a draft yoke, said coupler having projections on opposite sides of the shank thereof, said yoke having vertically spaced inseparable faces between which said projections extend and by, which said projections are engaged, and said yoke also having separable shoulders adapted to extend in front of and engage said projections, one of said separable shoulders being stationary and the other movable into and out of position in front ofa projection on the rear end of the coupler shank when the yoke and coupler are in assembled relation.

3. In a draft rigging, the combination of a coupler and a draft yoke, said coupler be ing provided on opposite sides at its rear with vertically extending pro ect ons one of which is of greater height toward its front than at its rear, said yoke having a forward end provided with vertically spaced faces for engagingly receiving said projections between them, and said yoke also being provided with separable shoulders adapted to extend in front of and engage said projections.

t. In a draft rigging, the combination of a coupler and a draft yoke, said coupler being provided on opposite sides at its rear with vertically extending projections one of which is formed with a downwardly and rearwardly sloping face, and said yoke having an inclined face for engaging said sloping face of said projection and having separable shoulders adapted to extend in front of and engage said projections.

5. In a draft rigging, the combination of a coupler and a draft yoke, said coupler being provided at its rear with oppositely extending projections one of which is formed with a downwardly and rearwardly sloping face, and said yoke having an inclined face for engaging said sloping face of said projection and .having separable shoulders adapted to extend in front of and engage said projections and having a forward end provided with top, bottom and side walls affording a socket for said projections, said top and bottom walls extending unequal distances in advance of said projections;

'6. In a draft rigging, the combination of a coupler and a draft yoke, said coupler being provided at its rear with oppositely extending projections one of which is formed with a downwardly and rearwardly sloping face, and said yoke having a face adapted to engage said sloping face and having separable shoulders adapted to extend in front of and engage said projections and-having a portion in advance of said last named face and on the opposite side of the coupler therefrom forming a fulcrum on which said coupler is adapted to rotate when being assembled with or disconnected from said yoke.

7 In a draft rigging, the combination of a coupler and a draft yoke, said coupler being provided at its rear with oppositely extending projections one of which is formed with a downwardly and rearwardly sloping face and one of which is of reduced size at its outer end, and said yoke having a face for engaging said sloping face and having separable shoulders adapted to extend in front of and engage said projections.

8. In a draft rigging, the combination of a coupler and draft yoke, said coupler being provided at its rear with oppositely extending trunnions one of which is formed with a downwardly and rearwardly sloping face and one of which is of reduced size at its outer end, and said yoke having a face for engaging said sloping face and having separable shoulders adapted to extend in 9. In a draft rigging, the combination of a coupler and draft yoke, said coupler being provided at its rear with a pair of oppositely extending trunnions one of which is formed'with a downwardly and rearwardly sloping curved face and the other of which is of reduced size at its outer end, and saidyoke having a face for engaging said curved face and having separable shoulders adapted to extend in front of. and engage said projections and having at its forward end a top wall and a bottom wall and forwardly flaring side walls constituting a socket adapted to receive said trunnions, said bottom wall at its forward end being provided with a curved surface forming a fulcrum upon which said coupler is adapted to rotate when being assembled with or disconnected from said yoke, and said top wall extending forwardly beyond said bottom wall.

In testimony whereof I affix mytsi nature.

WILLIAM J. EAN.
