GAR-COUPLING.

To all whom it may concern Be it known. that; .I, WILLIAM. ,McCoN- WAY, J12, acitizen of the United States, re:

ing railway vehicles to each other, andis especially applicable to, tender coupler though'not limited thereto.

The principal objects of the invention are to provide simple and efficient means for preventing drooping of theflcoupler head and for conveniently and readily adjusting the coupler vertically to compensate for the sagging of springs, wear of the wheels and other similar results of service aflectingthe' height of the coupler headabove the rails,

Generally stated, these ob ects are accom-,

plished by providing a coupler pocket and pivotally connecting the shank of a coupler thereto in such manner that the latteris capable of swinging laterally to the desired extent, one of said members beingprovided with slots or recesses and the other of said members being provided with flanges which are adapted to enter said slots to thereby maintain the coupler in a plurallty of positions of vertical adjustment above the track rails.

In the drawings chosen for the purpose of illustrating my invention, the scope whereof is pointed out in the claims, Figure 1 is a plan view of a tender coupler embodying my invention. Fig. 2 is a view showing the pocket member of the coupler in horizontal section on the line 52-52, Fig. 3, and illustrating the coupler in plan in one of its extreme laterally displaced positions. Fig. 3

is a side elevation of the coupler, the parts being inthe relative positions illustrated in Fig. 1; and Fig. 45 is a detail View illustrating theimanner of assembling thecoupler in the coupler pocket.

In the drawings, 1 indicates the coupler and 2 is the coupler pocket or member by which the coupler is attached to the tender or other railway vehicle. These two mem-v Specification of Letters latent,"

here are preferably :pivotally connected means of a pivot pin 8 which passes through anapertureinearthearear endofthe coupler-shank andthrough corresponding aper: tures near the inner end of the flaring recess of the pocket member into which'such coupler shank extends. .The rear end: of the coupler-shank-smay be formed, ifidesired,

with cylindrical bearing facesA- which'are concentric with the pivot pin openingin the coupler shank and which are adapted to transmit the force of ,bufiing shocks to, the correspondlngly, curved, bearing faces 5 upon the .interior of the, pocket member 2.

Projecting laterally from the sides of the tively small dimensions and correspond.

ingly light in weight, while yet serving to permit. an extended lateral swinging of the coupler 1 and tosimultaneously engage the flanges 6 on bothsidesof the coupler shank, thereby insuring effective vertical support to the coupler throughoutgits entire arc of lateral displacement.

As a further means for preventing drooping'of the head of the coupler 1, the rear end of theshank of the coupler is preferably formed with a rearwardly extending projection 8 which may beconveniently located in the plane of the supporting flanges 6 projecting laterally from the sides of the coupler shank. This projection or flange 8, which is of less height than that of the coupler shank, is adapted to enter and move withthe coupler in either of the corresponding slots or recesses 9 formed in the baseof the pocket member 2.

When the device is in service the laterally projecting flanges, 6 of the coupler shank engage and are supported by the lowerfaces orfloors of: the particular slots 7 into. which the said flanges6 may have been inserted in assembling the parts, while the rearwardly extending projection 8 at the end of the coupler shank engages the upper face or wall of the appropriate slot 9, means being thus provided both in advance and to the rear of the pivot pin 3 for preventing the drooping of the coupler.

For convenience of eflecting temporary repairs while on the road, the coupler pocket is, as shown, preferably formed with a flaring pocket so as to be capable of receiving any of the generally employed forms of pivoted couplers and the usual form of shims commonly adopted for adjusting the height of the coupler above the rails.

I claim:

1. In a device of the character indicated, the combination with a pocket member, of a coupler which is pivotally supported by said pocket member, means connected to said coupler and located in advance of the point of pivotal connection of the pocket member and coupler for preventing drooping of said coupler, and means to the rear of the said point of pivotal connection for preventing drooping of said coupler.

2. In a device of the character indicated, the combination with a pocket member, of a coupler adapted to be pivotally connected thereto in a plurality of positions of vertical adjustment, and means located to the rear of the point of pivotal connection of the pocket member and coupler for preventing drooping of said coupler, the same means serving to prevent drooping of the coupler in either of its said positions of vertical adjustment.

3. In a device of the character indicated, the combination with a pocket member, of a coupler pivotallyconnected thereto, said coupler being provided to the rear of its said point of pivotal connection with a projection, and said pocket member being provided with a plurality of slots each of which is adapted to receive said projection.

4. In a device of the character indicated, the combination with a pocket member, of a coupler pivotally connected thereto, said coupler being provided with oppositely ex tending flanges, and said pocket member being provided with slots adapted to receive the corresponding flanges.

5. In a device of the character indicated, the combination with a pocket member, of a coupler pivotally connected thereto, said pocket member being provided with a plurality of slots, and said coupler being provided with oppositely extending flanges which are adapted to enter thecorresponding slots of the pocket member to thereby vertically adjust the said coupler with respect to said pocket member.

6. In a device of the character indicated, the combination with a pocket member, of a coupler pivotally connected thereto, said pocket member being provided with a plurality of slots, and the shank of said coupler being rovided with a plurality of laterally exten ing flanges which are wider at some points than at others and which are adapted to enter the corresponding slots of said pocket member.

7 In a device of the character indicated, the combination with means for supporting a coupler upon a railway vehicle, of a coupler having means whereby it may be pivotally connected to said supporting means and having a shank which is provided with a plurality of oppositely extending projections that are adapted to overlap said supporting means.

8. In a device of the character indicated, the combination with means for supporting a coupler upon a railway vehicle, of a coupler having means whereby it may be connected to said supporting means and having a shank which is provided with laterally extending projections that are of less height than the height of the shank and that are adapted to overlap said supporting means.

9. In a device of the character indicated, the combination with a pocket member, of a coupler pivotally connected thereto and adapted to be assembled therewith in a plurality of positions of vertical adjustment, said pocket member and the rear end of said coupler being provided with interfitting means adapted to restrain vertical movement of the rear end of said coupler in its several positions of vertical adjustment.

10. In a device of the character indicated, the combination with a pocket member, of a coupler having a pivot pin opening in the shank thereof and provided to the rear of said opening with a horizontally extending projection of less height than the shank of said coupler and provided in advance of said opening and extending to the rear of the head of the coupler with a plurality of laterally extending flanges, said horizontally extending projection and said laterally ex- {Sending flanges engaging said pocket mem- 11. A coupler pocket provided with means 115 whereby a car coupler may be pivotally connected thereto, and having a flaring recess and being provided with a plurality of slots communicating with said flaring recess at the opposite sides thereof.

12. A coupler pocket provided with a pivot pin opening whereby a car coupler may be pivotally connected thereto, and having a flaring recess and being provided to the rear of said pivot pin opening with 125 a plurality of slots communicating with said flaring recess.
