POCKET ron ENGINE-COUPLINGS.

Specification of Letters Patent.

Application filed May 8, 1919. Serial No. 295,544.

To all whom it may concern:

Be it known that I, ARTHUR J. BAZELEY, a citizen of the United States. residing at Cleveland, Cuyahoga county, Ohio, have in-' vented new and useful Improvements in Pockets for Engine-Couplings, of which the following is a specification, reference being had to the accompanying drawings, in which Figure l is a side elevation of a-coupler pocket embodying my invention; Fig. 2 is a front elevation thereof; Fig. 3 is a bottom plan thereof; Fig. 4 is a side elevation similar to Fig. 1 but showing the shim and shelf supporting the coupler head in elevating position; Fig. 5 is a detail showing the manner in which the shelf is applied to the pocket; Fig. 6 is a detail of the shelf; Fig. 7 is a side elevation of a modified form of my invention; Fig. 8 is a bottom plan thereof. and Fig. 9 is a detail of the shelf shown in Figs. 7 and 8. 7

My invention relates to pocket couplers for engines or tenders. which have an extended floor or shelf adapted to engage and support the coupler head forward of the mouth of the pocket, in order to prevent drooping or sagging of the coupler head when in service. My invention consists in providing a supporting shelf which is capable of reversal to provide vertical adjustment of the oupler heads and to compensate for wear. My invention also consists in the construction and arran ement of parts which I shall hereinafter describe and claim.

Referring to the drawings, A indicates the coupler po'ket and B the coupler head. The pocket A is provided with the usual recess 2 for the reception of the coupler shank 3. the shank 3 and po'lret A are apertured for the reception of a pivot pin 4. by which the coupler is secured in. the pocket. The pocket A has a pair of forwardly extending arms 5 intended to support the extended floor or supporting shelf ing shelf C is a T-shaped p ece. the head of which has an arcuate forward surfa'e and consists in a pair of vertically extending and alternately used coupler supports 6 and 6 proje ting. respectively. unequal distances from the horizontal plane of the studs 7 which extend laterally and engage the upper surfaces of the arms 5 of the pocket. The rearwardly extending leg or central- The support- 7 member 8 of the shelf C terminates in the forwardly inclined projections 9. The

pocket immediately below the recess 2 has shown inFig. 5. "T he shelf is then rotated until the rearwardly extending leg 8 bears in the slot in the lip 10 and the forwardly inclined face of the projection 9 engages the inclined rear face of the lip 10. When the shelf is in this position it is prevented from moving forward by the engagement of the projection 9 against the lip 10, and can not move sidewise because of its engagement in the slot in the lip and between the arms 5, nor rearwardly because its studs 7 abut against the shoulders 11 of the arms 5.

The shim D is normally inserted between the top of the coupler shank 3 and the top of the recess 2 of the pocket A, and the shelf C is applied with the shorter coupler support 6 uppermost, as is shown in Fig. 1. When, however, it is desired to raise the coupler head, either because of wear of the pocket parts or because of settling of the locomotive springs, the shim D is inserted in the bottom of the recess 2 beneath the coupler shank-3 and the shelf C is inverted, as is shown in Fig. 4, thereby causing the longer support 6' of the shelf C to engage the under side of the coupler head at a distance commensurate to the elevation of the coupler and shank caused by the insertion of the shim D.

In Figs. 7, 8 and 9 I have shown a modification of my invention, in which the rearward extension of the shelf C consists in a short lug 12, which engages a projection 13 on the lower lip of the pocket and which is fastened to such projection by a bolt 14. Becesses 15 are provided in the arcuateshaped por ion of the shelf so as to straddle the arms '16 and thereby provide a more edective interlock between these pa rts.

The terms and expressions which I have employed are used as terms'of description and not of limitation and I have no intention in the use of such terms and expressions of excluding any mechanical equivalents for the, features shown and described, or pertensions and having a rearwardly extending tions thereof, lout recognize that various structural modifications are possible within the scope of the invention claimed.

What I'claim is:

1. In" acoup1erpocket acoupler head pivotally secured in said pocket, forward ex-.

tensions from the under side of said pocket, a reverslble shelf seated on said forward exportion engaging a portion of. said coupler pocket to prevent removal in a forward direction 2.' In aI'couplerHpocket,a coupler head pivotally secured in. said pocket; forward iextensionsqfrom the under side of said pocket, a reversihl'ishelf having laterally extending members engaging the said forward extensions, vertically extending couplerv supports, on said shelf extending unequal distances-from .thehorizontal plane of said members, and i' a .rearwardly extending member, engaging :a forward portion of the pocket;

the coupler head and maintaining it substantially in a horizontal plane, andtmeans on said extensions to prevent rearward and lateral. movement ofsaidshelf, said shelf also having a rearward extension engaging the coupler. pocket to prevent forward movementof said shelf.
