To all whom z5 may concern.' .I

Be it known that we, VILLIAM J. REGAN and ENooI-I Gannon, Jr., citizens of the United States, residing, respectively, at Vilkinsburg, in the countyl of Allegheny and State of Pennsylvania, and Pittsburgh, in thecounty of Allegheny, State .of Pennf sylvania, have invented certain new and useful Improvements in Railway VDraft `Ap- 5 bushing beingadapted to be bent and being provided with a projection adapted to pliancesv; and we do hereby declarethe following to be. a full, clear, and `exact descrip# tion ofthe invention, such as will enable others skilled in the art to which it apper-y tains to make and use the saine. Y

Our invention relates to railway draft apT pliances, and is particularly concerned withv bushings constituting wearing surfaces or liners for the slotsywith which car couplers and yokes are commonly fashioned for the reception of aconnecting key. Byjthe use of the bushings, which maybe of varying thicknesses, a single coupler casting made for their applieationinay be used in conjunction with the several sizes of keys now employed for connecting draft members of railway draft appliances and, moreover, the. bushings may be so fashioned as to afford f means for shifting the position of the key longitudinally of the key `receiving sloty of' the draft member. y

The principal object: of, thev invention is to produce for the,purposesfindicated abush-' ing which issimplein form, `readily removable so that it may be renewed with a mimmuin expenditure oflabor, and which is'pro vided with means for reliably maintainingj it 1n assembled position in the slot of, theV draft member upon which it is mounted.

The principal feature 0I Vthe invention, generally stated, consists in providing ya draft member, having a key receiving slot therein, with a bushing which extends into the slot and is furnished with inea-ns formed thereon for maintaining it iny assembled relation to said draft member, the lsaidbushing being adapted to cause said key to be positioned nearer one end of's'aid slot than 'the other.

A.l further feature of the invention consists inthev combination with a draftmem bei' formed with a key `receiving slot, of a split bushing mounted on the draft ineinber and extending into the slot, the said lustrated in dotted lines.

bushing being of increased thickness at one end and being adapted to be bent so as to cause it-'to assume assembled position.

Another feature of the invention consistsk hereinafter appear.

The railway draft appliance with which the invention is concerned is of the well known type involving` slotted draft members, such as a car coupler and draft yoke or links. which areoperatively connected by means of a key. The preferred forms of bushings illustrated in the drawings are especially well suited to form liners for the slots of'car coupler elements of railway draft rigging and, accordingly, their relation to various types of slotted couplers has been illustrated in the drawings.

In the form of the invention shown in .Figs 1 to et, inclusive, 1 indicates a car maintain said bushing in mounted position on the coupler.

lThe bushing 4; associated with the coupler Y 1 extends into the slot 2 of the latter and preferably constitutes a complete or cont-inuous lining for relieving the coupler of the wear of the connecting key (not shown). One end of the bushing may be of increased thickness as indicated at 5, so as to cause the connecting key to be positioned nearer one end of the slot, thereby enabling the location of the key longitudinally of the draft member to be modified may be desired. Upon one side of the bushing is provided projecting means adapted to extend into the interiorrecess 3 of the draft member so as to maintain said bushing in assembled position, the said means preferably consisting of a plurality of lugs orprojections 6 each of which is adapted to engage one of the bounding walls of the said recess. The bushing 1 is preferably split closely adjacent to the projections 6, as indicated at 7, thus permitting the bushing, which is capable of being bent and preferably is formed as a forging or of malleable iron, to be bent or deformed (see Figs. 1 and so as to enable it to be entered in the slot 2 of the coupler. After having been entered in the key receiving slot of the draft member, the portion of the bushing carrying the projections 6 is bent or forced into operative position so as to cause said projections to assume their assembled position within the interior recess 3 of the coupler, thereby maintaining said bushing in place. lt will be perceived that the construction is such that after thc bushing has been subjected to wear after being first put into service, it may be reversed so as to bring new wearing surfaces into operation.

The modified form of construction illustrated in Figs. 5 and 6 is generally similar to the construction heretofore described, eX- cept that the bushing 8 is open at the end opposite its thickened portion 5; and this construction also differs from that shown in Figs. 1 to al., inclusive, in that the projecting means provided on the bushing for entering the interior recess 3 of the coupler 1 to maintain the bushing in assembled position, are constructed as a single lug` or projection 9 instead of a plurality of separated lugs. Other 'details of construction shown in Figs. 5 and 6 being identical with those already described have been indicated by corresponding reference characters.

rIhe car coupler 10 shown in Figs. 7 and 8 is provided with a key receiving slot 11 within which is mounted a split bushing 12. This bushing is of uniform thickness throughout and the usual connecting key associated therewith (not shown) is therefore caused to be positioned centrally of the slot in the coupler. The bushing 12 is preferably provided upon one side with a plurality of spaced projections 13 corresponding in form and function to the projections G of the bushing 1. This bushing also `is adapted to be bent so as to cause its projections 13 to enter the interior recess 14 of the coupler 10.

Tlierform of bushing 15 illustrated in Fig. 9 is the same as that disclosed in Figs. 7 and 8 except that it is open at one end, corresponding in this respect to the construction shown in Figs. 5 and 6. This bushing is assembled with the coupler 10 by bending thc part thereof bearing the projections 13, in a manner heretofore described, as illustrated in dotted lines.

The car coupler 16 shown in Figs. 10 and 11 is of the type provided with two inter` secting key receiving slots extending at right angles to each other, one of them, 17, being adapted to receive a vertically disposed connecting key and the other, 18, being for thc receptionof a horizontal key for attaching the coupler to a draft yoke or the like. A bushing may be mounted upon the coupler 16 so as to form a liner for either of these slots, 17 and 18, depending upon whether the draft member associated with the coupler is attached thereto by means of a vertical key or by ,a horizontal one. Except for the differences in configuration necessary to tion of a vertical key.

junction with this coupler maybe the same in construction as thebushing 12 shown in Figs. '1 and 8 and heretofore described; and

accordingly these bushings have been indiv-i cated on the drawings bythe reference numeral 12 and the projections thereof have been similarly indicated by the'reference character 13. TW hen the bushingis assembled with the coupler 16 for cooperation with a vertical key, the projections 13 extend into the interior recessof the coupler constituted by the horizontal slot 18; whereas, when the bushing 12 forms aliner for the horizontal slot 18 its projections 13 eX- tend into the slot 17 provided for/the recep- In either case thel projections 13 when bent to assembled position cooperate withthe coupler 16 to maintain the bushing in place.V

The car coupler 19 illustrated in Figs. 12 and 13 is formed with a horizontal key slot 20 and with oppositely disposed interior recesses 21 communicating therewith, said recesses .preferably being of cylindrical form.

to accommodate a projection 22 on the bushing 23 forming a lining for the slot 20. The projection 22, which is slightly tapered or inclincd upon one sit e as indicated at 24, for the purpose of enabling it readily to be forced to assembled position, may be assembled in the slot of the coupler in a plurality of positions, the projection 22being received in one or the otherof the recesses 21 as the case may be. This permits the bushing when worn to be turned to offer a vnew wearing surface to the connecting key. The bushing is preferably split closely adjacent to vthe projection 22, as indicatedat 25, to permit it to be readily bent tol a position` allowing it to be entered in the slot 2O and its projection 22 to be easily forced into the cooperating recess 21.

Fig. 15 illustrates the slot 2O of the coupler 19 as being equipped with a bushing 26 identically like the bushing 23 except that it forms a lining extending only around the sides and one of the ends of the coupler slot. The bushing 2G` is provided with projections 22 like those heretofore described which are adapted to extend into either of the recesses 21 of ythe coupler 19 for the purpose of maintaining said bushing in alternative assembled positions.

4any of the forms of bushings embodying the invention lend themselves to simple processes of manufacture, as will be appreciated and they may be readily combined with the slotted draft members with very small expenditureoflabor without the use of special tools.

We claim i 1. In a railway draft appliance, the combination with a draft member having a vslot adapted to receive a key forming an eleL ment of the draft appliance, of a bushing mounted onsaid draft member and extending into the slot thereof, said.v bushing Vbeing adapted to cause said key to'be posiV tioned nearer one end of 'said slot than the other. j f
