To all whom'it mag cwwm: i Be it known'that Bruns` citizen of the United States,

residing et- Baltimore, in the State of .n

land, have l Improvements in Draft Rigging; and l do hereby declare the ollowin to be a full, clear, and exact description' eig the invention, such as will enable others'skilled inthe art to which a pertains to make and use the same.

iie invention relates to railway cars, and more rtioularly `to draft rigging therefor, and te primary object of the invention is to provide `a. simple, strong and vreliable the cushioning elef: and devices and in thereof as hereinafter provements in the.

The center or draft sills of the car are .designated b fthe reference numeral 1, and tothe outer aces thereof is connected a conventional torni of cheek-plates or sto cast` ings 2 each of which is provided with en elongated front slot 3 and a second elonted slot 4. It .will of course understood that the sills 1 are correspondingly slotted and they cheek castin 2'are preferably provided with bosses 5 w ichextend into the slots in the sills, as clearly shown in Fig. 1. The coupler stem 6 is provided with a transversely.y extending slot through which the key 7 is adato extenkigthe said key extending outwardly from the coupler through the/slots in the sills and through the slots 3in the cheek-plates 2. In rear of the coupler, and normali contact the same,'is the frontjfollowerlooks whlch l.is

*engaging the Application tiled July ad, 10. Serial No. wenn .maintained in position by means of the transversely extending key 9, said key normally forward ends of the slots 4 in the said cheek-plates. In rear of the follower 8 and interposed between the same and the rigid back sto' 10 is the cushioning 'unit 11 which prefere ly comprises a rectangular casing 12, a cylindrical barrel 13, friction blocks 14 adapted normally to contact the internal surface of the barrel 13, and a wedge .0r spreader blockl. lt will'of' course be understood that-some-form of spring mechanism is seated within the rectangular casing 12 of the barrel and acts as a cushion against the inward-movement of the friction b ocks and we 14 and 15, respectively.

' To operativel connect the coupler to the `cushionin mec anism l provide a pair of i@ or yo e members 16 each of which comprises a loop member 17 adapted to entend around and normally contact the rear tace e of the rectangular casing 12,and a forward extension 18 in which ll rovide the slotsI 19 and 20. Each of the said slots is preferably elongated to permit the rearward movements of the keys 9 and 7 which extend through the res ective slots. Adjacent their forward en the portions 18 of the said members.

may be provided with enlargements 21 which inc the bearing 'area again@ the forward ge of the ke 'i'. `.d carry iron, such yas 22, may be provide adapted to extend under and vform a support for the members 16 and the cushioning unit 1 1, said' carry iron being connected to the lower danges`23 of the sills 1 by means et bolts 24. r i

le it is believed that the operation oi the device will be clear to those skilled in the art, it might be stated that on an inward movement of the coupler the cushioning element 1l is held from movement by its contact with the stop casting 10, 'the latter y being ,rigidly connected to the inner oitl the sills in a conventional manner. .The links 16 are held from rearward movement by the contact with the `forward face of any lill@ contact with the'ends of the res ective slots '.3 and 4, and` when the coup er 6 is relieved from stram rthe parts return to tl'eir normal, position illustrated in Fig. 1, On the outward movement of the cou ler the ,links 16 draw the casing 12 forwar ly over the wedge and friction blocks the forward:

movement of which isV arrested by the front follower 8 which isheld stationary by reason of the engagement of the forward edges of the vkey 9 with the`forward ends slots 4. t

It will be observed that by forming the links with a loop member I am enabled to utilize the width or space between the inner faces of the sills. This construction is particularly advantageous in cases where the width of the sills prevents the use of a horipossible to employ a rigid back stop which bridges the space between the sills and acts as a tie to prevent the spreading thereof. `By providmgr the link members with loop portions I eliminate the use of -a key follower at the rear of the gear and hence materially shorten the over all length and.

at the same time avoid the necessity of sharp angular changes adjacent the rear end of the casing which are embodied in a horizontal' yoke.

Having now described my invention, Ywhat of the I `claim and desire to secure by Letters Patent is l 1. In a draft ri ging, the combination with a pair of 'dra sills, of a coupler, a cushioning mechanism therefor, said mechanism including a casing, a stop member connected to said' sills .and ada ted' nor mally to engage the inner face -o said cas-A ing, a followerinterposed between said cou ler and cushioningmechanism, and means or operatively connecting said coupler, follower and casin said means. comprising a pair of relative y thin s aced counter art for edsteel -members sli ably connecte to said coupler and follower, and each having a portion adapted to surround the said cas- 1n In a draft rigging, the combination with spaced draft sills, of a coupler, a cushioning mechanism therefor, said mechanism including a casing, a slotted follower,

`a stop member bridging the s ace between said sills' and connected to t e same'and adapted normally to engage the said casing, and means for operatively connecting said coupler and casing, said means comprising a pair?. of spaced counterpart nembers slidably connected to said coupler and each adapted to partially enclose the said casing, the inner ends of said members engaging the said casing on opposite sides ofthe said stop member, and a key passing through the said follower and adapted to connect the said members thereto.

3. A forged steel yoke for draft rigging comprising a pair of relatively flat counterpart members each of which com rises a loop Aortion and an extension, sai exten'- sion ing provided with a plurality of alined elongated slots.

In testimony whereof I aix my si ature.
