' To all whom z't may concern.'

Be it known that I, GooDnrcH Q. Lewis, a citizen of the United States, residing at Wheaton, in the county of Du Page and State of Illinois, have invented a certain new and useful Improvement in Railway-Car Draft-Rigging, of which the following is a full, clearconcise, and exact description,v

reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in railway car draft rigging.

One object of the invention is to provide a draft rigging of high capacity of the tandem type so arranged that the shock absorbing units may be inserted and removed without disturbing the yoke and draw bar.

Another object of the invention is to provide a draft rigging of the tandem type wherein is employed a horizontal yoke arranged to remain stationary under buff and having upper and lower, front and intermediate stops extending'between the sills and bracing the latter.

The invention furthermore consists in the improvements in the partsand devices and in the novel combinations of the parts and devices herein shown, described and forming the subject matter of claims.-

In the drawing forming a part of this specification, Figure 1 is a vertical longitudinal sectional View of-a draft rigging embodying my improvements. Fig. 2 1s a horizontal sectional view of the structure illustrated in Fig. 1 and'taken on the line 2-2 thereon. Fig'. 3 is a vertical, transverse s ectional view takenv substantially on the line V3 3 of Fig. 1. And Figs. 4, 5 and 6 are tical side flanges, the latter being suitably riveted to the sills 10. Each of said stops is further provided, at its rear end, with a vertical ange -16 to form a stop shoulder Specification of Letters Patent.

with forwardly and rearwardly extended flanges 18-18 riveted to the sills and additional strengthening tapered horizontal flanges 19-19. The rear stop or abutment block 15 is provided with a vertical front face 2O for the rear end of the yoke 21 to abut against and with side webs 22-22 riveted to the sills, the front wall 20 being suitably braced bv a plurality of horizontally extending webs 23-23- The' yoke 21 is arranged horizontally and is guided between the sets of front and intermediate stops, as clearly appears from the drawing. At their front ends, the arms of the yoke` are provided with elongated slots 24 to lreceive the coupler key 25 by which-the yoke is connected to the draw bar 26, said key also extending through elongated 'slots in the sills.

Each of the shock absorbing units, which are arranged in tandem, preferably comprises sets of twin arranged springs 27-257 and followers therefor. The front shock absorbing unit has the front `follower 17 and the front intermediate follower.28, the latter being shown more in detail iniFig. 5. As there shown, the follower 28 is recessed at its center as indicated at 29 to formed on the front follower 17, to slide therethrough. The column 30 is concaved on both its upper and lower surface to thereby form suitable seats for the twin arranged springs 27-27- The column 30, as clearly appears from Fig. 4 is larger at its front portion as indicated at 31, thereby forming shoulders 82-32 adapted to engage the front *intermediate follower 28 at the end of the bufling and draft movements and thus limit the compression of the springs. It will also be noted that each of the followers 17 and 28 is provided with suitable bosses 33 on which the springs 27 are mounted.

The rear shock absorbing unit comprises a front intermediate follower 34 and a rear follower 35 and twin arranged springs 27- 27, the latter being suitably separated by a combined spring spacer and limitin f block 36. The two sets of springs and fo lowers ing, a :floating pressure transmitting blockv are held in proper positionby detachable saddle plates 37 bolted to the lower flanges of the sills, the bolts being locked by clips 38.A

In order to operate the gear as a tandem gear under draft, the yoke 21 is provided at its center with inwardly extending lugs 39-39, each having a front shoulder 40 adapted to engage the rear face' of the follower 28 and pull'the latter forwardly under draft. To actuate the rear unit under buff- 41 (see Fig. 6) is provided which fits between the intermediate followers 28 and 34 and is engaged by' the rear end of the column 30. The lugs 39 are beveled rearwardly and outwardly as Vindicated at 42 and the sides 43 of the block 41 are correspondingly beveled, as appears from Fig. 2.

In assembling the device, the yoke is slipped in endwise, after which the' block 41 is placed in position between the intermediate stops 13 and 14.. The shock absorb- Aing units may then be inserted from below,

as is apparent and the draw bar finally inserted and connected to the yoke. The draft gear thus presented is of high capacity in that it comprises tandem arranged twin sets of springs, the parts may be readily assembled and disassembled, the stops are so formed and located as to present the maximum resistance to the strains imposed thereon; and the stops are also relatively small and brace the sills.

I. claim 1. In va draft rigging, the combination.

with draft members, of upper and lower,

horizontal. front and intermediate stops, a

lrear stop, a horizontal tandem yoke between said upper and lower stops, theyoke remaining stationary under buff, tandem arranged shoek absorbing units, insertible and removable from below, within the yoke, said i yoke actuating both units in' draft, and

means forv actuating Aboth units in buff.

2. In a draft rigging, the combination with draft members, of'upper and lower,

' horizontally extending front and intermediate stops, a rear stop casting extending between and secured to the sills, a horizontal lower to actuate the latter under draft, said yoke remaining stationary under buff, a column` extending from the front follower rearwardly, anda block interposed between the intermediate followers, said block being actuated by said column under buff to thereby move the rear intermediate follower rearwardly.

4. In a draft rigging, the combination with draft members and tandem arranged stops, of a horizontal yoke, front, frontv intermediate, rear intermediate, and rear fol` lowers, cushioning means between the sets of followers, a floating block interposed between the intermediate followers, and means for actuating said block from the front follower under buff to thereby compress the rear cushioning unit, said yoke having shoulders arranged to engage the front intermediate follower under draft.

5. In a draft rigging, the combination with draft members, upper and lower horizontally extending front stops, upper and lower intermediate stops, and a rear stop, of a horizontal yoke slidably mounted between the front and intermediate stops, said yoke remaining stationary under buff, tandem arranged shock absorbing units insertible and removable from below while the yoke is in position, said yoke having inwardly extended shoulders arranged to engage the front intermediate follower under draft to thereby move said follower forwardly, and.

means for operating both units in buff.

6.v In a draft rigging, the combination with' draft members, upper and lower horizontall extending front stops, upper and lowerv orizontvally extending intermediate stpp and a rear stop,`of tandem arranged shock/ absorbing units, a horizontal yoke guided between said upper and lower stops l and prevented from rearward-movement by
