CAR-COUPLlNG.

SPECIFIQATION forming part of Letters Patent No. 571,771, dated November 24A, ieee.

Application filed September 4, 1895. Serial No. 561,429, KNO modela To all whom, may concern:

Beit known that I, CHARLES LEE, a subject of the Queen of Great Britain, residing at San Antonio, in the county ot Bexar and State of Texas, have invented a new and useful Car-Goupling, of which the following is a speciiieation.

The invention relates to improvements in car-couplings.

The object of the present invention is to improve the construction of pin-and-link earcouplings, and to provide a simple and inexpensive one which will be capable of coupling automatically and which may be readily uncoupled without going between cars.

A further object of the invention is to provide a car-coupling which will be adapted to have its coupling-pin elevated and maintained in that position to enable a dying kick to be imparted to a ear, and of automatieally setting the parts in position for automatic coupling after such car has been cut oft or separated.

The invention consists in the construction and novel combination and arrangement ot parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view ot a ear-coupling constructed in accordance with this invention. Fig. 2 isa vertical longitudinal section al view of the same. Fig. 3 is a horizontal sectional view. Fig. 4E is a transverse sectional view. Fig. 5 is a detail perspective view of the spring-actuated block.

Lilie numerals otreferenee indicate corresponding parts in all the figures of the drawings.

l designates a draw-head mounted on acar 2 and provided with a shank or stem of a size and shape similar to those of the standard car-couplings in common use, and adapted to be readily mounted on the ordinary car having the usual pin-andlink ear-couplings without requiring any alteration in the construction ot the car or its draft connections. lVithin the draw-head is slidingly mounted a springactuated bloc-k 3, provided at its top and bottom with centrally-arranged rectangular pro- 50 jections i and 5, located at the front of the block and fitting in corresponding longitudinal grooves G in the top and bottom of the draw-head. 'lhese grooves ff are open at their front terminals to permit the sliding block to be removed from and inserted in the draw-head, and the block is also guided in its forward and rearward movements by a transverse pin 7, removably arranged in a perforation S of the block and projecting laterally beyond the same and iitting in horizontal grooves 9 of the sides of the draw-head. At the front terminal et the horizontal grooves 9 of the sides ot the draw-head are located perforations or openings l0, arranged slightly above the plane of the grooves 0 and adapted to permit the pin 7 to be withdrawn when the spring-actuated block is slightly elevated in the draw-head to cause its horizontal perforation to register with the openings or perforations ol the sides ot the draw-head. On the inner Afaces of the sides of the draw-head are arranged horizontally-disposed rectangular ribs ll., contracting' the width of the lougitudinal opening or throat oi' the draw-head, to enable a cylindrical spiral spring l2 to lit snugly in position in rear of the sliding block. The sliding bleek provided at opposite sides with grooves 13, corresponding to the horizontal ribs 1l. of the draw-head, and the spiral spring is strengthened by an inner spiral spring il and is interposed between the rear end of the sliding block and a removable stationary plate l5, provided at opposite sides with notches l G, receiving the .ribs of the drawhead.

The springactuated block is provided at its front with a bottoni. transversely-disposed beveled projection or iiange 17, adapted to 'form a continuation of the lower beveled portion of the draw-head, whereby a link 1S may be guided and caused to contact with the block. The top projection l of the block is adapted for supporting a coupling-pin 19 in an elevated position preparatoryT to automatic coupling, whereby when the sliding block is engaged bya link entering the draw-head the projection at will be carried rearward from under the coupling-pin, and the support being withdrawn the coupling-pin will fall into engagement with the link. The couplingpin is arranged in a coupling-pin perforation, the upper section or portion 2O of which is enlarged, and is provided with a round front portion and a rectangular rear portion to IOC adapt the coupling-pin perforation to receive the various forms of standard pins employed in car-couplings. A round, square, or oblong coupling-pin may be employed, and the coupling-pin perforation is provided at its top with an inclined seat 21, and the lower end of the coupling-pin is recessed at its rear side or edge to provide a corresponding inclined shoulder 22, conforming to the configuration of the seat 2l and adapted to interlock partially therewith to prevent accidental disengagement. The coupling-pin is ad tpted to engage the seat of the draw-head automatically when it is elevated, and does not require a train-hand to go between cars to set it. The coupling-pin is designed to be held in an elevated position on the seat 2l, to effect what is known as a iiying kick, and after the link has been withdrawn from the draw-head the sliding block is moved outward by the springs, and its upper shoulder or rectangular projection et engages the depending lower end of the coupling-pin and swings the same forward, carrying it from its seat and causing it to drop upon and be supported by the rectangular top projection t of the sliding block, whereby the couplingpin is maintained in position for automatic coupling. A link now entering the draw-head will come in contact with the sliding` block and will move the same inward from beneath the coupling-pin, and the latter will fall and engage and couple the link.

The draw-head is provided at its top with an upward-extending boss 23, surrounding the coupling-pin perforation and increasing the bearing of the coupling-pin, whereby the latter is held with greater steadiness and security when in an ele ated position, as illustrated in Fig. l of the accompanying drawings. The bottom portion 24 of the coupling-pin perforation is slightly vbeveled or en` larged at the upper face of the bottom of the draw-head.

The upward movement of the coupling-pin is limited-to prevent it from leaving the drawhead when uncoupling by means of a chain 25, having its upper end secured to the top of the coupling-pin and its lower end attached to the draw-head in a recess thereof. The chain 25 may be readily disconnected from the coupling-Lun when it is desired to remove the latter from the draw-head.

The link 1S may be of the standard form employed on railroads, but it is preferably provided with flattened ends 2o', having grooves 27. rlhe flattened ends of the link engage the flat front face of the sliding block, which will hold the link in proper position for guiding it into the mouth of a draw-head, and if the link should be pushed aside the springs and the block will return it in proper position if flattened ends are used, and the grooves increase the durability of the link and preserve the .flattened ends.

The coupling-pin is raised for uncoupling by means of a transverse rock-shaft 28, journaled on the car 2, and a link 29, provided at its inner end with a transverse head .JO and at its outer end with a hook 3l. rIhe head SO projects laterally from the inner end of the link and forms journals which are arranged in suitable bearings. The hook s connected with the coupling-pimand the rockshaft 28, which is provided at its ends with handles 32, has a central curved bend or arm 33, located beneath the link 29 and adapted to swing the saine upward. After the coupling-pin has been elevated the rock-shaft s released and swung downward against the ear.

It will be seen that the car-coupling is simple, strong, and durable, that it is positive and reliable in operation and is capable or receiving the standard pins and links, and that its stem or shank, by being of the standard form and construction, is adapted to ce placed on the ordinary construction of cars without necessitating any change therein.

Changes in the form, proportion, and the minor details of construction may be resorted to without departing from the p inciple or sacrificing any of the advantages of this im vention, such as varying the shape of the stein of the draw-head to adapt it to various forms of draft connections, of fluting it to uiminish its weight, and the like.

l. In a car-coupling, thecombination with a car, a coupling-pin provided a short distance from its lower end with a shoulder, and means for raising the coupling-pin without going between cars, of a draw-head having a coupling-pin perforation and provided at the rear of the upper portion thereof with a shou li der located above the upper wall of the link opening or cavity, forming a seat and arranged to be engaged automatically by the shoulder of the coupling-pin when the latter is raised, said coupling-pin projecting below the top wall of the draw-head when it is supported on said scat, and a spring-actuated block arranged to engage the depending portion of the coupling-pin, substantiallyas dcscribed.
