CARCOUPLING.

SPECIFICATION forming part of Letters Patent No. 554,970, dated February 18, 1896.

Application filed November 30,1895. Serial No. 570,718. (No model.)

To all whom, it may concern:

Be it known that I, OYEUs F. BAKE, a citizen of the United States of America, residing at Fullerton, in the county of Nance and State of Nebraska, have invented certain new and useful Improvements in Oar-Couplings; and I 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 of reference marked thereon, which form a part of this specification.

The object of this invention is to provide an improved car-coupling and means for holding the locking-bar out of an operative position; 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.

In the accompanying drawings, forming part of this specification, Figure l is a vertical sectional view of a car-coupling constructed in accordance with my invention. Fig. 2 is a plan view of the draw-bar and couplinghead and parts to which they are connected, the coupling-head being partly in section. Fig. 3 is a detail perspective view of the means for holding the locking-bar out of an operative position. Fig. 4t is a plan view of Fig. 3, and Fig. 5 is a plan View of the coupling-link.

A designates the coupling-head and B the draw-bar which passes through a central longitudinal aperture in the coupling-head and is attached thereto by a transverse pin b, the forward end of the draw-bar being formed into a head, which lies in a corresponding recess in the coupling-head. The couplinghead A is preferably made of a casting shaped so that the sides converge rearward, as shown in Fig. 2. The draw-bar and coupling-head are attached to the car by means of longitudinal beams O and C', which are secured to the under side of the car, to be substantially parallel with the sides of the couplinghead and a slight distance therefrom. The beams are connected to each other by crosspieces c c, c', and c2, the cross-pieces c c lying in recesses in the upper and lower sides of the coupling-head, while the cross-piece c' has an aperture through which the rear end of the draw-bar passes, and the forward end of the coupling-head rests upon the cross-piece c2. Encircling the draw-bar and interposed between the cross-piece c and the rear end of the coupling-head A is a helical spring C2, the tendency of which is to force the coupling-head forward, the movement in both directions being limited by the length of the recesses c c hereinbefore referred to. It will also be noted that an excessive rearward movement of the coupling-head would be prevented byits jamming between the beams O and Ct, the arrangement of said beams providing for this.

The link-chamber of the coupling-head tapers rearward, as shown in Fig. 2, and in the upper wall of the same is formed a recess in which the locking-bar D is pivoted, the forward end of the recess forming a shoulder a", against which the shoulder a2 at the forward end of the locking-bar bears when its free end is engaged by the coupling-link. To the free end of the locking-bar is connected a link d, which extends through an aperture a3 in the upper part of the coupling-head and is connected to the device hereinafter described for raising the locking-bar and holding it in a raised position. The forward end of the coupling-head is provided with vertical apertures to receive the ordinary coupling-pin.

E designates a casing or housing, which is provided at its lower end with outwardly-projecting flanges e, by means of which it is secured to the top of the car, and within this casing or housing is pivoted a block F, said block being preferably of metal, to give it weight, and is in the form of a segment, as shown in Fig. l,the pivot-pin f passing through the same adjacent to the angle thereon. To the forward end of the segment or block F is attached a chain or flexible connection f said chain being also attached to avertical rod d', which is connected at its lower end to the link d, extending from the locking-bar D. rIhe rod d' is guided in suitable links or eyes attached to the forward end of the car, and the lower end of the same is bent outward, as shown, to engage the link d.

The rear end of the upper part of the casing or housing E is cut away, as shown in Fig. 4, to provide for the movement of alever IOO 1o f2 in the segment or block.

F, which is secured to the rear end of the segment er block F and provides a means for operating the same to raise the locking-bar l). To hold the locking-bar in a raised position or out of operation the casing E is provided with a gravity-catch Gr, which is pivoted between apertured ears e e thereon and has a projection g, which passes through an aperture in the casing and engages an aperture The outer end of the catch is weighted to cause the projection g to automatically engage the aperture in the segment or bleek, and in order to operate said catch from the side of the car I attach a ilexible connection or cord g thereto and lead said cord to a suitable point at one side of the car.

The device herein shown and described is an improvement upon my previous patent, No. 160,294, dated March 2, 1875.

The operation of the parts will be readily understood from the drawings and foregoing description, the coupling of the cars being automatic when the lockingbar I) is lowered, as shown in Fig. l, for in this position the link lI, when it passes into the coupling-head, will raise the locking-bar, and the latter passing over the head 7L of the link will fall into position to engage the shoulder 7L thereof, the jar occasioned bythe coupling-heads coming together being taken up bythe helical spring C2, and when the train is being drawn forward the pivot-pin of the locking-bar will be relieved. of strain by the shoulder d on the upper part of the link-chamber. When it is desired that the ears should not couple when they come together the locking-bar D may be held out of au operative position by swinging the segment or block F back until the aperture f2 therein is engaged by the gravitycatch G.

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

l. The combination in a car-coupling, of a coupling-head shaped to present side walls which converge rearward, a draw-bar passed through a central longitudinal aperture in the couplingwhead and having a head which lies in a corresponding recess in said coupling-head, the draw-bar being secured to the coupling* head by a transverse pin; together with longitudinal bars or beams C and C converging rearward and having cross-pieces c c, c', and c2 rigidly secured thereto with which the drawbar and coupling-head engage, and a helical spring encircling the draw-bar and interposed between the cross-piece c and the couplinghead, the coupling-head being recessed to receive the cross-pieces c c, substantially as shown and for the purpose set forth.

2. In a ear-coupling, the combination with the coupling-head having a shouldered locking-bar pivoted therein, of a segment or block F pivoted within a casing and having an aperture or notch in one side of the saine, and a gravity-catch pivoted on one side of the casing and having a projection which engages the aperture or notch in the segment, the segment being connected to the locking-bar, sub stantially as shown and for the purpose set forth.

3. In a car-coupling, the combination with the coupling-head having a locking-bar piv oted therein, of a casing or housing E secured on top of the car, a segment F pivoted in said casing or housing and provided at its rear end with an operating-lever FQ a gravity-latch G pivotcd on one side of the casing and provided with a projection g adapted to engage a notch or aperture in the segment, and a cord extending from the gravity-latch to a point at one side of the car, the segment being connected to the locking-bar by a flexible connection f, rod d' and link d, substantially as shown and for the purpose set forth.

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