RAILWAY DRAFT APPLIANCE.

Application led September 12, 1923. i Serial No. 682,265.

4ableothers skilled in the art to which it ap ertains to make and use the same.

ur invention relates to railway draft appliances and particularly to bushings forming liners for the slots with wh1ch car coupler's and yokes are commonly provided for the reception of a connectingkey. By

the use of the bushings, which may be made of such thickness as circumstances may require, a single cou ler casting may be employed with any o the several sizes of keys now used.

The principal object of the invention is to l provide a bushing of the character indicated which is of simple form, easily applled, readily removable so that when worn it may be replaced by a new one, and is securely maintained in assembled relation to the draft member with which it is associated.

The principal feature of the invention, generally stated, consists in providing a draft member, having a key receiving slot therein, with a'bushing which extends into the slot, the said bushing being furnished with means cooperating withthe draft member for maintaining Vsaid bushing in as- A sembled position and being adapted to be deformed by bending so as to cause it to assume assembled relation to the draft member.

A further feature of the invention consists in the combination with a draft member having a key receiving slot, of a bushing mounted on said draft member and extending into the slot thereof, the bushing being formed with a projection, the draft member being provided'with a series of recesses for alternately receiving the said fprojection so as to maintain the bushing in a plurality of assembledrelations to the draft member,

and the bushing being adapted to be bent a key receiving slot therein, a split so as to cause it to assume an assembled position with respect to said draft member.

AnotherI feature of the invention consistsin mounting upon the draft member, having bushing which extends into said slot and is provided with a plurality of spaced projections adapted to enter corresponding recesses formed in the draft member, there being -a plurality of said recesses adapted to receive each of the projections and the bushing being formed of metal which may be bent to cause the said projections to assume an assembled position in said recesses.

`Other features of the invention pertaini ing to particular relations of parts andi structural details will hereinafter appear.

In the drawings chosen for the purpose of illustrating the invention, the scope whereof is pointed out in the claims.

Figure 1 is a horizontal sectional view of a portion of a railway draft mechanism embodying the invention.

Figure 2 is a side elevation of the rear end of the car coupler forming a part of the draft appliance illustrated in Fig. 1, the key slot bushing being shown as applied to saidcoupler.

Figure 3 is a side elevation of the forward end of the draft yoke forming one of the elements of the draft rigging illustrated in Fig. l, the key slot bushing being shown in assembled relation thereto,

Figure 4 is a detail elevational view of one of the bushings illustrated in Fig. 1, the bushing being shown as bent so as to be enered in a key receiving slot of a draft .mem-

Fi ure 5 is a plan view of one of the bushlngsillustrated in Fig. 1.

Figure 6 is a detail view in side elevation of the rear end of a modified form of car coupler for cooperating with the bushing.

Figure 7 is a plan view of the construction illustrated in Fig. 6.

The railway draft rigging illustrated in Fig. 1 is of the well. known type involving key connected draft members, `oneof which is lthe car coupler 1 while' theY other may be the usual draft'yoke 2. The key 3, which is well known and is indicated in. dotted lines in Fig. 1, passes through slots in the car coupler and the arms of the yoke. As

, mounted, land they are the rear end of the coupler stem is commonly cast hollow the slot therein for receiving the connecting key 3 is frequently formed as two alined slots 4, and each yoke arm is likewise provided with a slot 5. These slots are of somewhat greater size than the key 3 so as to afford Aspace for the bushings yhich enter the slots and engage the said y ey.

The bushings 6 which extend into the respective slots 4 of the coupler` may ladvantageously be formed as unitary members and preferably cover the entire inner surface` of the slots. lThey arev adapted to be deformed by bending so as to permit them to be assembled with and disassembled from the draft member upon which they are forged or made of mallea le iron.

Each of the bushings 6 isl provided with means for cooperating with the draft member to maintain said bushing in proper .as-

sembled position when the draft appliance is in service. For this purpose the bushing 'may advantageously be provided with a plurahty of spaced lugs or projections 7 one of which is adapte tofenter either of the corresponding recesses 8 with which the coupler is furnished on its outer side adjacent the key slot, while the other of said lugs 7 is adapted to have overlapping engagement wit the coupler within the hollow interior thereof. For economy of manufacture it is preferred in the case of the car coupler to utilize the hollow interior of the coupler stem 1 as the recesses for receiving the inner lugs or projections 7 of the bushings, as recesses on the interior of the coupler corresponding in form to said projections 7 would be somewhat diiiicult to clean out after the coupler is cast. -The bushing 6, which isrounded .at its ends to conform to the curvature of. the slot, is preferably split near one end closely adjacent to the projections 7, as indicated at 9, thus facilitating, as shown in dotted lines in Fig. 2, the bending `of the bushing to permit its entry into the key slot and also enabling the subsequent bending necessary t'o bring the projections 7 into cooperative relation with the draft member to be easil accomplished. To permit the projections 7 to enter and fit snugly in the recesses 8, the said projections are preferably tapered, as indicated at 10, and the recesses 8 are likewise tapered correspondingly, as indicated at 11.

Except that they are of less width in the direction of length, the bushings 12 for the slotted armsof the draft yoke 2 are identical in form with those heretofore de` scribed, and accordingly similar reference4 characters have been applied to the corresponding details/of construction. Each of t e yoke arms is preferably provided on its referably either Y inner and outer faces adjacent the key slots 5 with a plurality of recesses 8 either of which is adapted to receive the corresponding projections 7 of the bushing.

The form of bushing 6 illustrated in Figs. 6 and 7 is identical with that heretofore described. 'lhe coupler 13 is, however, provided on its outer sides with an increased number of recesses 14 for alternativel receiving the.lugs or projections 7 o the bushin It w1ll be perceived that in all the forms of construction illustrated the bushing is capable of occupying a plurality of assembled positions with respect to the draft member upon which it is mounted, thus enabling said bushing, after it has been worn, to be taken out and reapplied so as to present new surfaces to the wearingA action of the key. But it will be appreciated that certain novel features of the invention are independent of the capability of assembling the bushings in various relations tothe draft members with which they are associated.
