CAR-COUPLING.

SPECIFICATION-forming part of Letters Patent No. 443,916, dated December 30, 1890. Application filed October 2, 1890. Serial No. 366,800. (No model.)

To all whom it may concern:

Be it known that we` FRANK HARVEY and JOHN KANE, citizens of the United States of America, residing at Renovo, in the county ot' Clinton and State of Pennsylvania, have invented certain new and useful Improvements in Car-Couplings; and we do hereby declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters `ofreference marked thereon, which form a part of this specification.

This invention relates to improvements in car-couplings, the object thereof being to provide an improved construction of the coupling and draw-head embodying means for automatically securing the interlocking coupling-hooks closed; and it consists in the construction and combination of the parts, as will be hereinafter fully set forth, and particularly pointed out in the claims. l

In the accompanying drawings, forming part of this specification, Figure l is a perspective view showing the interlocking hook open. Fig. 2 is a horizontal sectional view. Fig. 3 is a detail perspective view of the latch.

A refers to the coupling-head and draw-bar, and B the coupling-hook which is pivoted to one of the forwardly-projecting ends of the head by a pin a. This coupling-hook B is attached by a knuckle-joint, the outer central portion thereof having a vertical wall b, which abuts against the vertical portion b of the draw-head, so as to limit the outward movement of the hook B, the limit of said outward movement being shown in dotted lines, Fig. 2, and in full lines, Fig. l. rlhe head and hook are provided with shoulders c and c', which limit the inward movement of the coupling-hook, which movement is also limited by the locking-arm C, abutting aga-inst the wall of the draw-head, as shown, said draw-head being recessed tov receive said locking-arm, the upper and lower walls of said recess extending across the central portion of the draw-head to the intersection of the opposite forwardly projecting portion thereof. This locking-arm, which moves snuglyin said recess, prevents any play of the coupling-hook other than a horizontal pivotal movement upon the pin a. The end of the locking-arm C is reduced to form an inclined portion C', anda recess d is formed in said locking-arm between the inclined end thereof and the projecting portion, within which the coupling-hook of the opposite coupling will partially lie when the couplings arc in engagement with each other.

Immediately rear of the coupling-head a draw-bar is located and has formed thereon a stop E, having a vertical edge e, against which one side of the latch will abut, and the outer wall of this strip is rounded, so as' not to retain foreign substances. Rear of the stop E the draw-bar is provided with a central wall G, to which is pivoted, by means of a pin g, the latch F, said latch having a bifurcated rear portion, the front end thereof having a beveled recess, as shown at 7L, under which the end C of the coupling-hook will pass and raise the same automatically when the coupling-hook is moved from the position shown in dotted lilies, Fig. 2, to that shown in full lines.

The coupling-hook can be raised when it is desired to uncouple the cars by the rod I, which passes through an opening in the coupling-head and engages with an eye beneath said opening.

It will be obvious that a car-coupling constructed as shown and described will automatically interlock, and to uncouple the cars it will only be necessary to elevate the catch by drawing upon the rod I.

I am aware that prior to myinvention many improvements have been made upon twin jawcouplers of the type known as the Janney coupler; but by the construction herein shown and described I avoid the employment ot' springs and have practically only two movable parts-viz., the coupling-hook and the catch-and the coupling-hook is so secured to the coupling-head that both its inward and outward movement will be limited.

I am also aware that prior to my invention a car-coupling having a gravity locking attachment adapted to be used in connection with the interlocking hooks, as shown in Pat- IOO ent No. 412,879, dated October l5, ISSJ, has been provided, and I do not elairn such construction as my invention; but

That l do claim as in v invention, and desire to secure by Letters Patent, is-

1. The combination, in a ehznnbered drawhar having; n` coupling-head formed integral therewith, the eouplingdlook pivotally ttttaehed thereto, seid Coupling-hook having a locking-arm with the recesses (l, beyond which said locking-arm is red need, said red need portion having its upper end beveled, n latch horizontally piroted to :L vert-ien] wnll torrned integral with the drmwlieavd, the front end of said latehheimY oppositely beveled on its underside from the end ot' the locking-2mn, and means for elevating;` Said lnteh, suhstantially as set forth. l L). The eombinntioinin n enr-coupling, of at l draw and couplingl head constructed snbsthnt tially as shown and provided with n central tint vertical portion G, to which the lnteh l?, having' its rear end bitnrented, is pivoted, zt

raised portion or stop E, having' :t straight inner fnee and rounded outer portion, the forward end ot' the lzt-teh extending beyond the stop, and n colliding-hook having nn extended andoppositely-beveled portion whieh engages with the front end ot the latch, substantially as set forth. V

3. The combination, in :tear-Coupling, of n draw-head carrying' within the seine zt hori- Zontnlly-pivoted lnteh, the rear end of which is bifnreated and pivotnlly secured to the vertical wel) G ot` the drnw-head, :1nd a stop formed integral with 'the draw-heed and provided with :t straight waihagainst whieh one side of the latch nhuts, substantially ns set forth.

In testimony whereof we ntlix onr signatures in presence ot two witnesses.
