Be it'knoyvnthat I, 'Inl-i OnvrLLn WRIGHL citizen ofV the' United residing in the city of Baltimore, State of Maryland, have invented certain neiv.- and, Auseful Improvements in ,DrabY-okes, ot-
S'tates of America',
`which the following is a specification.
This invention A and particularly to'a twopart yoke consisting o iii jaiv member and a loop `The jaw' member is slotted to receive one i or two keys and .thel loop may be connected member is slotted tothe jaw member b yvany suitable means'. Preferably'the loop is pivoted to' swingv latera-ily relativelyto the Vjaw member. f
I n the preferred' form .of the invention, the jaw member is niadewi'th a longitudinal opening to permit '.the 'drawfbarto pass therethrough and engage the followers within the loop. As shown, this opening is'ol' suliicient size to admit the yoke, and the jaw rearwardly-from the front l' at the 'top and bottom, the-slots terminating in sockets or seats which receive correspond- ,ing studs on the ends .of the loop.
In setting'np -the device, the loop .is inserted from the front-into the opening in the jaw member, the studs `on the ends of the. arms of the loop-entering the slots, and as the loop is moved'v to the rear, they 'become seated in the sockets at the ends of the slots. 4The longitudinal opening-in the jaweed .

and thetension member or loop'is given a sufficient degreeof Hexibility to eliminate all danger of breaking due to lateralino tion of the draw-bar' in winding bends, etc'. Further, the ]aw member and loop arerde- 'tacliably c m1'iected-,and .maybe easilv and .conveniently separated so.
that either part can be quickly replaced in case of breakown.
The accompanying drawings illustrate a through the yoke, certain parts being shown is avieiv half in plan .and -half in' central, horizontal section.

'Referring to the drawings by numerals, each of which is applied to the same ele- 'ment in the different igures of the drawingfein the preferred form oi? the invention, asshoivn,'the yoke consistso'f a jaw member V1 and 'a loop or tension member 2. he loop is (itil-shape, -the arms 3 being provided atl their forward ends, one With a studdprojecting upward and the other with a depending `stud y5. he Vj aw. member has to admitthe rear end of the draw-bar cientsize in a vertical the loop exclusive of the .studs el- 4and To receive and coperate with the studs, the jaw member is g open at the front and extendingrearwardly, preferably vtapering as shown, and provided at their rear ends lwith .seats or sockets S, shown as .arcuate in form., the radius oit 'the arc being slightly greater than the radius of the studs 4 and 5.
Thus, in setting up the draft gear, the
A'rear end of theloop is inserted in the member from the front, the studs 4 5 entering the slots 7, tothe rear to the position shown in Fig. l 'untilthe studs are'sea'ted in the sockets or seats 8. v rilhus the loop and jaw iiueniber are pivotallylconnected, forming a flexibleyoke, the aperture -in the jaw member 'beingA of sulicient 'lateral dimension to 4permit the loopto s 'ing lateral y through a considerable are; 15."fithin 'the yoke the usual shockabsorbing'means not'shou'n ,is mounted..

This key coperates will the sills and the shock-absorbing n'ieans'; Q the usual or any suitable manner. ln Fig. 5 have shown a similar yoke which ris cut away on theline .l2 inclosing the slot'll. The yoke- 'asthus` formed ad :ptef 'to be used with the single-lierY type' of draft gear, as well as with the two or three key gear.

At' the saiiie'tiine, the-loop may be conveniently made of wrought ironor soiftsteel.
