WILLIAM J'. GEDDERT, OE ALLIANCE, OI'IIO, ASSIGNDR TO AMERICAN STEEL FOUNDRIES, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

POCKET-COUPLING.

To all whom, it may concern Be it known that I, WVILLIAM J. Gnnnnn'r, a citizen of the United States, and resident of Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Pocket-Couplers, of which the following is a specificm tion.

My invention relates to draft devices for railway cars and has particular reference to a novel pocket coupler for use in connection therewith.

It is customary in connecting couplers to engines and tenders in many instances to provide no spring draft rigging .merely attaching a short shank coupler to a pivot on the end sill of the car.

Many forms of pocket couplers have been proposed, all of which I believe contemplate the employment of a separate pivot pin whereby the coupler is connected to the pocket casting.

My invention contemplates the construction of a pocket coupler of two parts interlocked in such manner as to provide a permanent fixed pivot which cannot by any means become lost. The danger of breakage is also practically eliminated, the coupler head being pivoted to the casting in such manner that its removal is accomplished only by the removal of three bolts instead of as formerly one cotter pin.

The invention will be more readily understood by reference to the accompanying drawings, wherein,

Figure 1 is a plan View of a coupler pocket constructed in accordance with my invention with a short shank coupler in place therein; Fig. 2 is a rear elevation of the pocket showing the interlocking device whereby strain is removed from the attaching bolts. and, Fig. is a section on the line 3-3 of Fig. 2, showing also a pair of shims in place these shims being provided to secure adjustment of the height of the coupler as required.

Referring more particularly to the drawings it will be seen that I provide a casting 10, having bolt apertures 11, therein and a rear discontinuous recess 12. The casting 10. is provided with a forwardly extending ledge or shelf 13, on which the coupler shank 1 1, is adapted to rest. Extending upwardly from the shelf 13 is a hollow boss 15. the opening through the center of which is Specification of Letters Patent.

slightly tapered downwardly as indicated in Fig. 3. The mating casting 16, is provided with a downwardly extending lip or lug 17, fitted within the recess 12 of the casting 10, and interlocking therewith when the parts are in normal relation. Projecting downwardly from the casting 1G, is a tapered bolt or rod 18, having a reduced threaded lower end 19, with which a nut 20 is adapted to be engaged. This rod is adapted to fit closely within the tapered aperture inthe boss 15, and to be securely held in place by means of the nut 20. The casting 16 is provided with bolt apertures 21.

In service the lower casting '10 is rigidly and permanently bolted or riveted to the end sill (not shown) of a car or engine. A coupler having an aperturcd shank is fitted on the hollow boss 15. whercu 'ion the mating casting 10 is placed in position with its downward projection 18 within the hollow boss 15. and bolts are passed through the openings 21 therein into the end sill. After the nut 20 is adjusted, the intertittcd cast ings become practically as one and any removal of the coupler shank therefrom other than after a reino 'al of the bolts would re quire a. practical destruction of the pocket.

It will be noted that the shims 22 are provided these being shown in Fig. 3 above the coupler shank. As the engine or car settle upon their springs and the coupler should be elevated. one or more of the shims are removed and placed beneath the coupler.

I claim:

1. A coupler pocket, comprising a horizontal shelf provided with an upwardly projeeting hollow boss, a cover mounted above said shelf. and cover-securing means passing downward through said hollow boss, substantially as described.

2. A coupler pocket consisting of upper and lower members carrying portions interfitting to form a holding connection between the upper and lower members of said pocket, one of said interfitting portions constituting a pivot, substantially as described.

3. In a coupler pocket, the combination of a shelf having an upward projection, a cover, and a projection downward from said cover, said downward projection intertitt-ing with the upward projection on said shelf, one of said projections forming a vertical pin on which a coupler shank may pivot, substantially as described.

In a coupler pocket, the combination of a wall adapted to be secured to a car end sill, a shelf projecting outwardly from said wall, a boss projected upwardly from said shelf, a cover adapted to be associated with said wall and shelf, said cover carrying a boss adapted to register and interfit with the boss projected upwardly from said shelf, and means for securing the parts in assembled relation, substantially as described.

5. In a coupler pocket, the combination of a wall having a right angled shelf, a hollow boss projected upwardly from said shelf, a cover, a pin projected downwardly from said cover into the opening through said hollow boss, and means for securing the parts in assembled relation, substantially as described.

6. In a device of the class described, the combination of a coupler pocket consisting of upper and lower members, said lower member having an integral hollow upwardly projecting boss and said upper member having a downwardly projecting integral lug adapted to register with the opening in said boss, and means for securing said upper and lower members to a car end sill, substantially as described.

7. A sectional coupler pocket, one of the sections having a pivot lug projecting therefrom, another pocket section having a projection inter-fitting with the pivot lug, and means for holding together the pocket sections.

8. A sectional coupler pocket, one of the sections having a pivot lug projecting therefrom, another pocket section having a projection to interfit with the pivot lug and form a holding connection between thev pocket sections.

9. A two-part coupler pocket, consisting of an upper and a lower section, an integral pivot lug projecting from one of said sections, and an integral projection on the other of said sections adapted to interfit with the pivot lug and form a holding connection between the said upper and lower sections.
