NETE REUBEN J ONES, OF ATLANTA, GEORGIA, ASSIGNOR OF THREE-FOURTHS TO CHARLES A. SINDALL, OF SAME PLACE.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 361,823, dated April 26, 1887.

Application filed January 22, 1387.

T @ZZ whom it may concern.:

Be it known that I, REUBEN JoNEs', a citizen of the United States, residing at Atlanta, in the county of Fulton and State Georgia, have invented a new and useful Car-Coupling; 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,

IO reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to that class of carcouplings in which the draw-heads are coupled by means of a pin in each, and a link connecting two pins,the object being to still further improve the inventions for which Letters Patent of the United States were granted to me on the 2O 25th day of May, 1886, No. 342,517, and on the 28th day of September, 1886, Nos. 350,061 and 350,062.

My invention consists of improved form of and means for operating the link-lifter, of improved means of holding the inner end of the link on the lifter, and improved form of and means of operating the pin-lifter and sustaining' the pin and preventing it from being drawn out of the draw-head, as will be hereinafter more 3C fully described.

In the accompanying drawings, Figure 1 is a side view, mostly in section, showing the interior oftwo draw-heads. Fig. 2 is a side View of one draw head, the pin and link being in position as when coupled. Fig. 3 is a top view of a portion of a coupling, showing a horizontal section of the upwardly-projecting lugs at the center of the rock-shaft, also showing the top of the pin-lifting arm. Fig. 4. is a perspective 4o of the link-lifter and the rock-shaft carrying the upwardly-projecting arm, whereby it is operated, and their relative position when in place in the draw-head. Fig. 5 is an enlarged cross-section of the link-lifting cam and its shaft. Fig. 6 is a view of the inner side of the pin. Fig. 7 is a plan ofthe hole through which the pin passes in the upper and lower portion of the draw-head. Fig. 8 is a detail showing the inner side of one ofthe two upwardly-projecting lugs that carry the rock-shaft.

Serial No. 225.208. (No model.)

vIn the iigures, like reference-marks referring -to like parts in the several views, A represents a draw-head, B a link, and C a pin provided with a hole in its upper end for connection with the pin-lifting arm, as described in my patents referred to above, and

at the bottom end with a projection, c, which I usually form by s waging out a portion of the metal from the body ofthe pin.

c is a groove at the back of the hole for the 6o projection c on the draw-pin.

D is the link-lifter, having a downward projection on its lower' side, d, and a rearwardlyprojecting tongue, di.

c is a cam on the rock-shalt E, which is pro- 55 vided with an upwardly-projecting arm, c'.-

F is a latch pivoted in the upper part of thedraw-hcad on the pinf.

G is a link-lifting arm, which is pivoted loosely on the rock-shaft g. On the side of 7: the link-lifter G is a horizontal `projection or arm, g.

II is the upwardly-rising lugs that carry the rock-shaft g, and are provided with the counterbores 7L, (shown in Figs. 3 and 8,) to accoml75 modate the pins on the rock-shaft g on either side ofthe link-lifting arm G, and h is a shoulder on one o-f these lugs. The rockshaft g is provided with an arm, I, and coupling J, and is operated by handles, as shown in my Let- 8o ters Patent No. 350,062, Fig. 1.

The earn e on the rock-shaft E is somewhat narrower vertically than the diameter of the rock-shaft E, as shown in Fig. 5, and the opening K through one side of the draw-head is of corresponding shape, by reason of which shape the shaft E is held in its position.

In the bottom of the draw-head is a recess,

L, which as nearly as possible conforms to the shape ot' the link-lifter D, except at its rear 9o end or under the tongue cl, where the recessis made considerably deeper to allow the depression of that end by the cam e, which will raise the link, as shown in the right-hand drawhead, Fig. 1, the link-lifter tilting on the downward projection cl and the rear end of thelink being held down by the weight and friction of the latch F. In this position the link will enter the left-hand draw-head, and coming in contact with the latch F, a portion of which Ioo lIO passes under the projection c and supports the pin C, and which, being forced back on the incoming link, will allow the pin C to drop and complete the operation of coupling the two draw-heads. To uncouple them, the rockshaft g, which turns freely in the hole by which the armG is pivoted to it, is turned in the direction (see Figs. 2 and 3) that will bring the arm I in contact with the arm g ofthe pinlifter G. The communication of this motion of the rock-shaftg will raise the pinlifting arm g and with' it the pin O.

In case the draw-heads are to be immediately drawn apart, the pin is to be held in that position until by the withdrawal of the link from the draw-head in which the pin is raised the latch F will drop to the position shown in the left-hand draw-head, Fig. 1, and hold up the pin by engagement ofthe shoulderf with the projection c on the pin. rIhis pin C is always placed in the draw-head before the latch F is pivoted in its position by the pinf, and the semicircular end around this pivot is of such radius as will prevent the passage of t-he projection c', and consequently the accidental Withdrawal of the pin from the draW- head.

In case the draw-heads are not to be immediately drawn apart, but instead set to stand uncoupled until drawn apart, the rock-shaft g is pushed endwise until the pin-lifting arm G will rest on the shoulder h' on one of the lugs H, which shouldalso be done in case it is desired to `push the cars without coupling them. The pin-lifting arm G may be provided with hole n, by which a chain or cord attachment may be had with the top of the car, as shown in-my Letters Patent No. 350,061, and for the purpose therein described.

The pin-lifting arm G, I usually make by doubling a ilat bar of iron and welding Ait for a part of its length. One of the prongs thus formed being bent at an angle, forms the arm g', While the other is left unbent and carries the hole or holes by which the connections are made. I prefer this construction, althoughit might be constructed in various other ways and answer the same purpose as long as it is loosely attached to the rock-shaft g and has an arm, g', and holes, as described.

Having thus described my improvement, what I claim as new, and desire to secure by Letters Patent of the United States.` is

1. In the draw-gear of a railway-car, the draw-head A, link B, pin C, having projection c', and the latch F, having the shoulder f', and pivoted in a position to prevent the withdrawal of the pin from the draw-head, and to sustain it when not in use, substantially as described.

2. In the draw-gear ot' a railway-car, the combination of the draw-head, link, and pin, with a bifurcated link-lifter, D,pivoted in the bottom of the inside of the draw-head, and having the rearwardly-projecting tongue d', the rock-shaft E, and its cam e, arranged to depress the rear of the lifter and raise the link, substantially as described.

3. In the draw-gear of a railway-car, the combination, with the drawhead, of the bifurcated link-lifter D, rock-shaft E, provided REUBEN JONES.
