IMPROVEMENT lN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 149,462, dated April 7, 1874; application filed February 28, 1874.

To all whom it may concern:

Be it known that I, JACOB D. GARDNER, of Nashport, in the county of Muskingum and State of Ohio, have invented a new and valuable Improvement in Gar-Couplers and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a representation of a plan view of my car-coupler. Fig. 2 is a sectional view, and Figs. 3, 4, and 5, detail views, of the same. Fig. 6 is a sectional, and Fig. 7 an end, View.

This invention has relation to railroad-car couplers of the self-coupling kind; and it consists in a hooked and recessed draw-bar, a hooking-arm, which is pivoted to the draw-bar and held down in place by a spring, a cam-lever for lifting the hooking-arm, and a rocking tongue, which will guide the head of the coupling-link out of the draw-bar when the hooking-lever is raised, as will be hereinafter explained.

In the annexed drawings, A designates a draw-bar having a flaring mouth, on the inner sides of thescheeks of which are formed inclined shoulders to a. The rear upper ends of the shoulders at a terminate in backwardlydirected hooks b b, in rear of which recesses are made, in which the head of a couplinglink, L, plays. 0 designates an arm, which is fitted into the upper side of the draw-bar A, and constructed with hooks h at the rear termination of its under-beveled end, which hooks are directed backward and have a channel between them for receiving the shank of the coupling-link. The arm 0 is pivoted to the draw-bar at p, so that its front end, which is held down by a spring, S, and a rod, 1", is allowed vertical movement for coupling and uncoupling. D represents a camlever, which is pivoted at c in a slot made vertically through the arm 0, in rear of the hook h. The upper end of this lever will, in

practice, have a chain attached to it, which will pass up through the platform of a car, and be secured to some object where it-will be convenient for use, or, in case of freightcars, the chain will be carried to the top of the car. The lower cam-shaped end of the lever D passes through a slot made through a tongue, t, and bears upon the bottom of the recess in draw-bar A, in which the arm 0 is fitted. By raising the longer arm of lever D, the hooked end of the arm 0 can be lifted high enough to release the coupling-link L. Beneath the hooked arm G is applied the slotted tongue 25, above referred to, the front portion of which tongue extends nearly to the hooks I) b. The rear end of this tongue t is turned upward at an obtuse angle, so that when the arm 0 is raised, its rear beveled end will raise the front portion of the tongue t to' the position shown by Fig. 6.

The links are constructed with fiat heads I on each end, as shown by Figs. 3 and 4, or when cars having my couplings on them are to be connected to cars provided with the wellknown draw-heads and pins, I use links having a flat coupling-head, Z, on one end, and an eye, 02, through the other end, as shown in Fig. 5.

When two cars are moved together, the flat head 1 of the coupling-link will ride up the inclined shoulders at a, press up the hooked end of the arm 0, and drop into the recess behind the hooks b h, as shown in Fig. 2. In this position of the parts the head llies on the tongue t and beneath a spring, 8, which is secured to the arm 0 back of the hook h.

WVhen the lever l) is drawn up, the tongue t, following it, will lift the head of the link in line with the highest ends of the shoulders or a, and allow the head I to be drawn out of the mouth of bar A.

The small spring 8 is intended to force the coupling-head free of the hooks h when the arm 0 is raised.

What I claim as new, and desire to secure by Letters Patent, is

1. A draw-bar, A, hooked at b, and shouldered at a a, in combination with the hooks h on the beveled end of pivoted arm 0, the lever D, and lifting-tongue t, substantially as and for the purposes described.

2. The spring S and its rod 4", combined with the hooked arm 0, tongue t, and the hooked draw-bar A, substantially as described.

3. The spring S, combined with the hooked arm 0, tongue t, and hooked draw-bar A, substantially as described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JACOB D. GARDNER.
