GAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 266,720, dated October 3], 1882.

Application tiled July 27, 1882.

T 0 all whom it may concern:

Be it known that I, LEANEY RECIIT, a citizen of the United States, residing at l.latte City, in the county of Platte and State of Missouri, havein vented certain new and useful Improvements in Car Couplings; and I do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilicd in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and'to the letters and figures of relerence marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in car-couplings; and it consists in the constrnction and arrangement of parts, as will be hereinafter more fully described and claimed.

In the annexed drawings, Figure l is a vertical longitudinal section of my improved coupling with the parts arranged in a coupled position. Fig. 2 is a similar view with the parts uncoupled. Fig. 3 is a horizontal section. Fig. 4 is a transverse sectional elevation on line 00 wofFig. 1; and Figs. 5, 6, and 7 are details, to be hereinafter referred to.

hike letters indicate like parts.

The letter A represents a draw-head, which is attached to the underside ot'acar, atone end, in the usual manner, and may, if desired, be provided with a spring at its rear end to preventjarring when the cars are coupled. The mouth of this draw head A is made flaring; but it is preferably built in with blocks having beveled outerfaces, so that there isjust enough space to receive and support the coupling-lin k. In the rear ot'the draw-head may be formed an enlarged cavity, B, having curved walls, as shown in Figs. 1 and 2; and in said cavity a supporting block or dog, (J, is pivoted by means ofthe pivot-pin c, passing transversely through the draw-head, and through said dog 0, near its under side. This dog 0 is preferably of a curved or semilunar shape, to correspond with the curved outline of the cavity B, and it is preferably provided at one end with a bushing or wearing-plate, as shown.

D is a coupling-pin, which is preferably composed of the guide-pin d, the transverse connecting portion (1, and the coupling pin or post (2, as shown in Fig. 4. The guide-stand- (No model.)

ard d is placed in a vertical recess or slot formed in the forward portion of the drawhead A, a little to one side ot' the mouth of the same, and its lower end is provided with an adjustable nut to prevent it from being entirely withdrawn from said draw-head. The post or pin (1 is also surrounded by a coiled spring for the purpose of diminishing-jar. To the upper end of this post (I one end of the transverse portion d is rigidly attached. The opposite end of the portion d extends across the draw-head A to about the center thereof, and is detachably connected to the upper end of the coupling-pin d}, which plays in a vertical slot or recess formed in the center of the forward portion of the draw-head. The upper end of the pin d is square, and provided with a shoulder, upon which the forked end of the portion (1 rests. The parts (1 and (I? of the coupling-pin D are connected by a bolt passing through them. The underside ot'the transverse portionofthe pin Dis provided with a bracket, through which is passed one end of a rope or chain, E, the opposite end of which is provided with a spiral spring, and is attached to the root" or upper part of the car.

The form of link which I prefer to use in conjunction with my coupling is shown in Figs. 1 and 3, and consists ofa solid strip, F, of suitable material, provided with longitudinal slots ff near its ends for the reception of the coupling-pin.

When it is desired to hold the coupling-pin D permanently in a raised position I provide a block, Gr, (see Fig. 7,) having notched or con caved ends, which block is of such size as to rest diagonally against the parts (I d and beneath the part (1 of said pin D, as shown in Fig. 5, and thus prevent the pin from falling down into the draw-head.

Instead of using the pivoted supporting block or dog (J above described, I prefer to use a rectangular sliding block, 0, which is formed with'its front face curved to conform to the rounded end of the link, the rear end of the block being recessed for the reception of the end of a spring, I). This sliding block U is provided with a slot, through which is passed a pin, 0, which serves to restrict its play. \Vhen this form of supporting-block is used the cavity in the rear of the draw-head is the same size as said mouth,'except at its extreme rear end, which is slightly diminished in order to more firmly embrace the springD set therein.

11; will be understood that instead of bifurcating one end of the transverse portion 01 and squaring the upper end of the pin d of the pin D, I may perforate said transverse portion (1 and place it over the part (1 until it rests upon the collar formed on said part, and then secure it in place by means ofa bolt and washer, as shown at 3 Fig. 6.

By attaching suitable levers to the end of the car and connecting them with the link and pin said parts may be operated from the side of the car.

It will be observed that by raising the pin 1), which can be accomplished from either the top or side of the car, and then withdrawing the link the pivoted supporting block or dog 0 will fall forward and downward until it rests upon the bottom of the draw-head, over the pin-hole in same, while the pin will fall upon said block and be held in a raised position. When the link enters the mouth of the drawhead it will come in contact with the dog 0, so as to raise and force it back and permit the pin D to drop into its proper place in the link, thus automatically coupling the cars. The operation is the same when the block 0 is used, except that the spring D forces said block outward until it comes beneath the part d of the pin D. The construction of the pin D is such that should the part d become broken it could be readilyremoved and replaced by a new one,

and the joint will also allow said pin d to have slight lateral play to correspond with the mo-' tion of the cars. The nut is so adjusted upon the part d of the pin D as to prevent the pin d from being entirely Withdrawn from the draw-head, and the part cl also serves to guide the movement of the pin d It is obvious that a link of ordinary construction may be used with my coupling device.

Having thus described my inveution,what I claim as new, and desire to secure by Letters Patent, is-

1. In a car-coupling, the combination, with the recessed draw-head A and coupling-pin D, composed of the vertical parts 61 d and horizontal portion d, of the supporting-block G. substantially as shown and described.

2. In a car-coupling, the combination of the recessed draw-head A, horizontal spring-slide O, coupling-pin D, composed of the vertical parts at d and horizontal part d, and the link F, substantially as shown and described.

3. In a car-coupling, the combination of the recessed draw-head A, coupling-pin D, composed of the parts 61 d 6?, having spring-conneotion E, extending to the top of car, link F and means for supporting the pin when the link is withdrawn, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
