Specification of Letters Patent.'

Application led November 30, 1914. Serial No. 874,661:

To all ywhom t mag/concern.'

Be it known that I, JOSEPH HARRIS, a citi- `-zen of the United States, residing at Chif tively small expense; vin which the yoke isk employed to prevent the rearward movement of the `rear follower; and in which the parts may be readily applied tothe car and taken ofi' of the same.

In the drawing forming a part of this specification. Figure 1 is a vertical sectional view of aV draft rigging showing my improvements in connection therewith. Fig. 2 is a horizontal sectional view taken substantially on the line 2-2 of Fig. 1 and Fig. 3 is a` vertical sectional view taken substantially on the line 3 3 of Fig. 1.

In said drawing, -10 denote the center sills, which, as shown, are in the form of channels and which also act as the draft sills or members. The sills are slotted as indicated at 11` to receive a stationary key 12y which is held in place and prevented from accidental removal by means of a cotter 13. Mounted on the key 12 and between the sills is a box-like member A. which, as shown, is in the form of a casting substantially rectangular in cross section, having an upper horizontal wall 14, lower horizontal Wall 15 and vertical side walls ll, the latter having integral forward extensions 17 slotted as indicated at 18 topermit the pas-l sage of the key 12 therethrough. Forwardly slidably mounted within the member A is a yoke B having upper and lower arms 19- 19 and rear connecting portion 20. At their forward ends, the arms 19-19 are each provided with outwardly or upwardly and..

downwardly turned shoulders 21-21 adapted to engage the front edges 22 of the upper and lower walls 14 and 15 to prevent rear'- ward movement of the yoke. The free ends of sald yoke arms are also provided with 1nwardly turned shoulders 23 which engage the usual upper and lower shoulders 24 formed on the butt of the draw bar 25. Integral side flanges 26'are also provided on the ends of the yoke arms which fit over the side walls of the drawbar butt. The draw bar is provided with' an elongated slot 27 for the reception off-thel key 12- and which permits forward and rearward movement of the draw bar relatively to said key.

lVithin thev yoke are mounted a front follower 28, rear follower ,'29 and any suitable shock absorbing device, which I have indicated as a friction mechanismBO. A saddle plate 3l is also provided to properly support the yoke and gear.

The operation of the device is as follows On forward movement of the draw bar, the

rammed .ruiy 25, raie.

yoke pulls forwardly on account of the enl gagement of the shoulders 23 and 24, ther`ev by moving the rear follower forwardly and compressing the gear between it and the front follower 28, which is held stationary by the member A. Upon rearward movement of the draw bar, the yoke is prevented from rearward movement, due to the engagement of the shoulders 21 with the edges 22, and consequently the gear is compressed between the front follower 28 and rear follower 29 and in this manner the yoke and member A act as rear stops for the rear follower. In the case of unusually heavy gears, it may be desirable to provide supplemental stops for the rear follower to absorb the heavy bufing shocks and I have shown such stops at 32 in Fig. 1, although it will be understood that these are not absolutely necessary and do not form apart of my invention, their use -being optional with the manufacturer.

Throughout the specification and claims, it will be understood that I use the terms yoke, draw bar, followers, gear and stops preventing spreading of the yokev arms and with respect to said sills,

detachable means for securing said member stationary to the sills.

2. In a` draft rigging for railway cars, the combination with sills, of a continuous band mounted between said sills, a yoke slidable forwardly within said band, a draw bar slidable within said band, means for preventing rearward movement of the yoke within said band, and engaging the latter and means for holding said band stationary said band maintaining the operative connection between the yoke and the drawbar.

3. -In a draft rigging for railway cars, the combination with draft sills, of a draw bar, a yoke, a hood-like member surrounding the yoke and draw bar butt, said member serving as a front stop, and means for detachably securing said member stationary to the sills, said means comprising a key passing through slots in said member,.draw bar and sills.

4. In a draft rigging for railway cars, the combination with sills, of a draw bar, a yoke, said yoke and draw bar having interengaging shoulders, a hollow box-like member, said yoke being provided with shoulders arranged to engage said member, said member acting as a front stop for a front follower, and means for lsecuring said member to the sills, said, means comprising. a key lpassing through said member and the draw r. 5. In a draft rigging for railway cars, the

combination with sills, of a member stationary with respectto said sills, member preventing rearward movementv of the yoke, a draw bar, means for pulling the yoke forwardly upon forward movement of the draw bar, and a key for detachably supporting said member.

6. In a draft rigging for railway cars, the combination with center sills, of a draw bar,

a yoke, means for pulling the yoke forwardlyI upon forward movement of the draw bar, a.

band-like member encircling the arms of sald yoke and the draw bar butt, shoulders on the arms of said yoke adapted to engage said member to prevent rearward movement of the yoke, and a removable horizontal key extending through slots in said member and in the draw bar. i

7. In a draft rigging for railway cars, the 'combination 'with slotted sills, having an elongated slot, a band-like member surrounding the draw bar butt, a yoke having the.ends thereof.l mounted between walls of said member and the upper and lower faces of the draw bar, the free ends of said yoke arms wardly and outwardly turned shoulders, and a key extending through the slots in said sills, slots in the side walls of said member Iand the elongated slot in the draw bar.
