CAR-COUPLING.

` SPECIFICATION forming part of Letters Patent No. 325,923. dated September 8, 1885.

Application nlavJune 4,198?. (No moda.)

To all whomV it may concern.-

Beit known that I, GEORGE J OnEsFEn` GUsON, a citizen of the United States, residuseful Improvements in Ga1(louplings, of

l which the following is a description.

Figures l and 2 are vertical longitudinal sections of the draw-head, showing the different positions of the coupling device.

The object of my invention is to provide a cheap, durable, and simple carcoupling,which shall be automatic and positive in its action, and which uses the ordinary link and takes the draft in the same way as the common pin, and which will also t any car, and will not get out of order from being battered.

It consists, mainly, in the peculiar construction of a coupling device, in combination with a spring for holding it to the opened or closed position, and cooperating With the same for automatic action, as will be hereinafter more fully described.

In the drawings, A represents the drawhead, which has a tapered mouth, and has its rear end constructed in the usual form to adapt it to the timbers of the car. The middle part of the draw-head is chambered vertically to receive the coupling devices, and this chamber opens' through both the top and bottom of the draw-head.

B isvthe coupling device, which, in general shape, resembles the small letter h. The vertical portion or stem b b constitutes the pin portion, of which the upper part, b, has

. a bearing against the shoulder c at the top of the draw-head, while the part b has a bearing against the shoulder c at the bottom of the draw-head, so that when the draft of the link is against this portion b b it has a positive bearing both above and below the link, like the ordinary pin, which gives a solid and positive draft. The other curved or back part, d, of the coupling device is made with a guideslot, e, through it, that is nearly vertical or parallel with the vertical stemV b b', the upper end of this slot being, however, slightly inclined to the rear. Through this slot passes the guide-pin C, which holds this peculiar coupling device in the chamber, and 5o which coupling device is inserted into the drawbar through the opening in the bottom, and the pin C afterward passed horizontally through the slot e. This guide-slot e and pin C determine the direction of movement for the coupling device. To hold this coupling device positively in its opened or closed position, a spiral or other form of spring, D, is seated in a cavity in the upper part of the` draw-head, and bears at its lower end upon a shoe, E, whose toe f fits into a notch, g, on the top of the curved part d. When the coupling device is down and closed on the link, as in Fig. 1, the tension of the spring D is transmitted to it by the toe of the shoe at a point between the pin C and the stem b b of the coupling device, thus positively holding the coupling device in place against acci dental disengagement from the link. When, however, the coupling device is raised, which is effectedv by a cord or chain attached to the top of stern b, the coupling device rises nearly vertically for a short distance. As soon, however, as the lower branch, b', rises above the shoulder c the backward pull on the cord or chain causes the toe of the spring-shoe to pass over to the rear side of the guide-pin G, which springthen holds the coupling device in an elevated position, slightly inclined to the rear at the top, with the lower portion of 8o the bend d resting against an abutment-pin C, and with the top of bend d resting in the abutment or shoulder h, formed in the back of the draw-head, all asshown in Fig. 2. When in this position, the car is ready to be coupled, and A i when the link of the opposing car enters this draw-bar it strikes the back part d of the coupling device, and, in tilting the latter forward, throws the spring-shoe to the front of pin C, where its tension forces the whole 9o lcoupling device down into the closed position.

By means of this coupling a shorter link can be used than in ordinary draw-heads,

thus avoiding so much slack in the length of the train. The coupling devices are also held in place from gravity, so that, even'if a spring should break, the coupling does not become ineffective. The coupling,` is also certain in its action, and the back-lash of the train has no eifeet in deranging it.

Having thus described my invention7 what I claim as new isl. The Combination, with 2n draw-head, of a tilting and sliding coupling device made in the general shape of the small letter h, with its front or stem portion tted to bear against shoulders at the front of the drawhead, and its rear curved part being` oonneeted to the drawhend by a. slot and pivotpin, and a. spring and shoe or bearing for the spring adapted to be shifted from one side to the other of the pivot-pin, substantially as and for the purpose described.

It ishereby lcertified` that in Letters Patent No.1325,923, granted September 8, 188.5,V upon the application of GeorgeJ. Ferguson, of Greenville, Texas, for an improvement in Car-Couplings, an error appears inthe-printed specification requiring correction as follows: In line 3, page 1, the Words the United States should be stricken out 'and the Words Great Brttdtninserted instead; and that the said Letters Patentshould be'read with this correction therein that the same may kconform to the` record of the.`

case in the Patent Office.
