TRANSOM DBAFTQGEAR.

Specification of Letters Patent.

Patented July 6, 1909.

Application filed April 15, 1907. Serial No. 368,395.

" ()hio, have invented certain new and useful Im roveinents in Transom Draft-Gear, of

. which the following is a specification.

My invention relates to the draft mechanism of railway cars, its object and purpose being to provide a draft means Which may be bolted or otherwise secured to the side or outer face of the body bolster, and which may be readily removed or detached when occasion demands it. A construction of this character allows the shocks due to bu thug and pulling to be comparativelyevenly distributed throughout the car underframe and is not imposed solely or largely upon the center sills. A draft frame is bolted to the front or outer face of the bolster, the bolts passing through. the bolster itself and also through a back or tail piece lying against the back face of the bolster opposite the end of the draft frame. In this manner a rigid and secure connection is made with the body bolster of, the car. Near its forward end this draft frame has an abutment or stop against the opposite faces of which abut the ends of coil draft springs. Adraft beam is provided, to the front end. of which the coupler is secured and to its'rear end is fastened a yoke, the draft springs being interposed between the end of the draft beam, the yoke, and the abutment or stop of, the draft frame. A draft mechanism of this type niay be readily attached to any of -the'usual styles of bolsters Without change. and in case of damage it can be removed i replaced with facility.

On the accompanying drawing which forms a part of this specification I have illustrated the preferred embodiment of my invcntion.

-Eigurc 1 is a plan view of the draft gear showing the same attached to a body bolster; Fig. 2 is a longitudinal central section of the structure shown in Fig. 1,; and Fig. 3 is an end view of the draft frame illustrating the same fastened to the front face of the bolster.

The body bolster of the car may be of any standard or convenient shape or style, and

in the present instance I have illustrated one,

each side of which is composed of two overlapping angle bars-10 and f. Atop and bottom plate 12 and 13, respectively, cover the upper and lower faces of the body bol ster and act as tension and compression members.

My improved draft rigging includes a draft frame, designated as a whole 14, comprising a horizontal to i plate member 15 with ears 15 adapted to e fastened to thecar sills and a similar bottom plate 16, the inner ends of which are joined and connected by well 17,

the external surface of which is shaped to conform to the contour of the side of the body bolster at that part Where the draft frame is boltcd'thcreto. At its front end this draft frame has a vertical, hollow, abutment Wall 18 connecting the top and bottom '7 plates 15 and 16, a pair or more of webs l9 connecting and strengthening the two out side portions of the wall. As is customary, the bolster is equipped with the kingpin bearing 20 which acts also to space the sides 7 5 of the bolster apart, and on the rear side of the bolster opposite the end of the draft frame I provide a back or tail piece 2ilshaped to conform to the back side of the bolster and overlappim the edges of plates 12 and 13. 8

A pair of bdlts 22 afford convenient means for securely fastening together the draft frame, bolster, and tail piece so that a riq'id and strong connection is secured. It wil be noticed that the tail piece assists in strcngthcn- 8 ing the connection with the bolster and also acts to distribu'u the strain more uniformly upon the bolster. In the top plate 23 which is riveted or bolted to the top of the bolster,

and to the top of the draft frame I provide an additional means for securing an cll'ccti'vc connection between the bolster and the draft rigging. It should be noticed that back of the abutment wall 18 the upper and lower horizontal plates 15 and 16 are equipped with shoulders 24 and 25, and that the p are 16 extends some little distance forwardly beyond the cndof plate 15, its upper surface having a shoulder 26 immediately below the end of plate 15. lower part of this dra ft frame, which is cast in one piece, there is supplied ulong thc lower surface of )late 16 one or more strengthening ribs 27. "he remainder of the draft rigging includes a hollow draft bcam 28 to the front end of which is fastened in any convenient or desirable manner the shank of a couplerZQ. This draft bcainis preferably cast in. one piece and includes the top and bottom Walls 30 and 31 and the diverging vertical walls Us In order to strcnglhcn the I through holes in the yoke legs.

and 33. Atits inner end this draft beam is considerably wider and on each side has a pair of laterally extended apertured ears 34L.

It will be apparent from an ins motion of Fig. 2 that the draft beam is considerably reduced in the -vertieal section between the coupler end and the inner end, and that the latter end is strengthened and firmly held in position by a pair olbraces 35 on the top and oottom. a pair of spring seats or pockets 36, and to the ears 3% on opposite sides of the draft mechanism are fastened the legs 37 of a yoke 38 by means of pins or bolts 39 passing through the apertures of ears 34 and also The cross piece 38 of the yoke passes between the abutment wall 18 and the inner end Wall 17 of the draft frame, as is clearly shown in Figs. 1 and 2. To strengthen the cross part of the yoke it has on its outer face a number of ribs 39 integral therewith. The inner face or surface of the cross member of the yoke has a pair of spring seats, the walls 40 of which are adapted to cooperate with the stops 24 and 25 to limit the outward travel of the yoke, while the Walls of the spring pockets 36 co-act with the'end of the top plate or wall 15 and the shoulder 26 to limit and restrict the inward travel of the draft beam. interposed between the draft beam and the abutment wall 18, and also between the yoke and the abutment or stop wall are four pairs of inner and outer compression draft springs 41', 42, 43 and 44. in order to reduce the weight of the structure to some extent without a sacrifice of strength the casting may have the openings 4-5, 46 and 4-7, but of course their presence orabsence in no way affects the value of my invention.

When the coupler shank is pulled forwardly the draft beam 28 and the attached yoke travel in the same direction compressing the rear or back springs 43 arid 4i and through iltits inner end this draft beam has i 1 l 1 l l l r l l i i l a l 1 r i l l l l l 1 and 26 and the end of tho hori'lzont'al top wall 15 of the draft frame. in case the draft rigging becomes damaged or injured and it is advisable to detach or remove the same this can be quickly and readily accomplished by taking oil the nuts or bolts 22 and cutting; the rivets or unfastenino' the bolts which socure the draft frame to the top or cover plate 23 and to the ear sills.

To those skilled in this art it will be apparent that numerous minor mechai'iical changes may be made in the structure shown and described. Without departure from the substance of my invention or sa'crilice of i ts benefits.

I claim:

in a railway car, the combination oi a bolster, a single-piece draft iranie having horizontal top and bottom walls, an inner end wall joining said top and bottom walls, and shaped to conform to the front face of said bolster and an outer abutment wall also joining said top and bottom walls, means to fasten said inner end wall to the front fare of said. bolster, a draft beam, a spring interposed between said draft beam and abutm'ent a yoke fastened to said draft beam, and a spring between said yoke and the opposite side of said abutment, substantially as described.
