, .i ,1110. whom may concern.' y 1' Be it known that I, CHARLES E. DATH, a

citizen ofthe United States, residing at Chi- .cago\ in the countyof Cook and State'of Illinois, have invented a certain new and useful Improvement in Draft-Rigging Yokes,

' of which the following is a full, clear, conoise,` vand .exact descriptionf, reference being `had to the accompanying` drawings, forming t' a part of this specification. AThis invention lrelates to improvements In fdr'aft rigging yokes.

'n For many years railroads and railroad supply manufacturers have been desirous of providing a yoke and'draw bar connection, 'wherein the latter may be 'readily detached y Withoutgdropping the draft oear or yokeand .having 'the partsso arranged that the at` taching means are suitable for use with any standard draw barwhether the same is provided witha coupler key slot or not, and wherein slotting of the sills is avoided. As

' is well known, detachable draw bar and yoke 4`connections' are being used more and-more f 'by :railroads and difficulty has beenenperienced in providing a draw bar and vyoke connection which is attachable to old types of draw bars, since it is found that many old draw bars now inservice are not provided witlra coupler key slot. Furthermore,v many in 4the' novel combinations of the 'parte and devices here; shown, described or claimed.`

i' l. l n` the dr., Jini-f forming a part-oi this specifiatioin' 1 is a partside eleva- "tion, part vertical section, of ayoke and draw l, har` showing my improvements in connection jtherewi- Fig. 2 is horizontal,,longitudiy nal. sectie.w taken substantially on `the line 2--'-2 of a front end elevation ofthe improved yoke. F 1g. e 1s a detail of the railroads object to havingvthe draft sili's Vslotted for the reception of a' coupler perspective ofthellocking block employed with my improvements.` ,And Fig. 5 is a ver- -ticalysectional View olf a. portion of a draft structure illustrated in Figs. 1 to l, A designates generally a cast steel yoke of tandem design having an upper arm 10, lower` arm 11, rear member 12, and integral hollow central thimble or post 13. At its front end, the yoke A is provided with a substantially rectangular hollow hood or.head having an upper wall 14, side walls -15, andv a lower, vtransversely extending bridge or connecting piece 16.. At its upper end, the hood or head is provided with a transverselyI extending front gib or shoulder 17 and a. rear transversely extending gib or shoulder 18 adapted to engage the front and rear shoulders of the draw bar butt 19. At its loWerend, the hood of the .yoke is provided with anupstanding gib (ir-shoulder 20 against which the rear face of the ydraw bar butt lengages under buff. To support the draw bar buttl in proper position and to lock it in' place, l have provided `a detachable' and removable looking block ingly formed groove or recess 23 inthe hood of the yoke. At its front end, the lock block 21 is provided wit-h an upstanding gib or shoulder 24 arranged to engage'the lower front shoulderiof the draw barbutt.' Said block 21 is also provided with a. depending ,flange 25 which lits against the inner face of the bridge 16 and is adapted to be bolted 'thereto as by bolts 26-26. I also provide an angle plate 27 arranged as most' clearly shown in Fig. l, said plate 27 having its upper flange extended rearwardly andl seated within a transversely extending slot 28, formed in, the front lface of the block 21, whereby the angle plate -27 assists inv supporting theblock 21 in position.l y The hood of the yoke is also provided'with shoulders 29- 29 on the innerfaces of the side walls thereof just abovejthe bridge 16, said shoulders having theirl rear facescurved to ,correspend withthe curved frontface SOo'f the gibor 'shoulder 24, yThe block 21 is. also` rounded at its rear end as indicated `at 31, in

order to facilitate insertion of the block 2l.,

l pivotal connectionwith the adjacent part of the yoke. When the block 21 is removed,

the draw bar butt may then be lowered sufliciently for the upper shoulder thereof to clear the gib 17 whereupon thedraw bar may bev pulled out. The parts are assembled by steps the reverse of those above described, as will be understood.

In buff, the draw-bar butt will engage the lshoulders 18 land 20 and thereb force the yoke rearwardly to actuate t e tandem gears. In draft,l the draw har butt will engage the gibs orshoulders 17 and 2-1 and in this'connection, it will bednoted that the shoulder 24 is rigidly braced by the inwardly extending shoulders 29, the block 21 as an'entire'ty being also braced by engagement with the bridge 16 and flange 3 2.

In the yoke illustrated in Fi 5, the arrangement is the sameas that iustrated in the other figures except that the gibs or shoulders 18 and 20 of the yoke shown in Fig. 1 are omitted, so that upon buff or inward movement of the draw bar, the' latter- .will lengage directly the front follower of the gear and may slide inwardly independently of the yoke.

From the preceding description, 4it will be seen that the draw bar and yoke connection -`which I have provided `is adapted for all 'standard types of draw bars, the draw bar may be replaced or removed without disturbing the gear or the yoke, no slotting of the sills is necessary, and all the parts are readily accessible from beneath the draft rigging even though the draft sills may extend down below the lower partof the yoke.

Although I have herein shown and described what I now consider the preferred.v

method of carrying outmy invention, the same is merely illustrative and I contemplate all such changes and 4modifications that come within the scopelof the claims appended hereto.
