DANIEL W. DEAL, OF TODDVILLE, ASSIGNOR OFl ONE-HALF HIS RIGHT TO JONATHAN P. STEWART, OF VINTON, IOWA.

IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 157,093, dated November 24, 1874 g application filed May 18, 1874.

To all whom it may concern Be it known that I, DANIEL W. DEAL, of Toddville, in the county of Linn and State of Iowa, have invented a certain new and useful Improvement in Oar-Couplers, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which my invention appertains to make and use the same, reference being had to the accompanying drawing forming a part of this specification, in whichi Figure l is a vertical longitudinal section, representing my improved car-coupler as it appears when the cars are attached; and Fig. 2 a vertical longitudinal section, representing it as it appears when the cars are detached.

Like letters refer to like parts in the different f1 gures of the drawing.

My invention relates to that class of carcouplers which are automatic in their action; and consists in a novel construction and arl rangement of the parts, as hereinafter more fully set forth and claimed, by which a cheaper and more effective device of this character is produced than is now in common use.

The extreme simplicity of my invention renders an elaborate description unnecessary.

In Fig. l, A B are the shackling or coupling bars; O, the connecting l rod; J, the draftspring; E, the link; F, the connecting-rod spring; and G the platforms of the cars. The bar A has a recess, H, formed by the bar and spring J, and the bar B a recess, I. The rod C is provided with a dart-shaped head, D, at one end, and with the enlarged cylindrical bulb K at its opposite end. The lower end of the link E is attached by a staple to the bulb K, in such a manner that when the spring F is pressed down upon the platform G the rod C will be partially rotated, and its dart-shaped head D brought into the position shown in Fig. 2, and when the spring F is released the rod will assume the position shown in Fig. l. The spring J is provided with a jaw or shoulder, a, which, in conjunction with the corresponding shoulder cformed in the bar A, prevents the dart-head D from being withdrawn from the socket H when the rod C is in the position shown in Fig. l.

From the foregoing the nature and operation of my invention will be readily understood by all conversant with such matters.

The cars being unshackled and the spring F elevated, as in Fig. l, if they are brought together, the head D will strike the inclined surfaces .r of the entrance to the recess H, thus causing the spring J to bend downwardly and permit the head to enter said recess, where it will be caught and held by the shoulders a c, shackling or coupling the cars in a manner plainly apparent; The cars being thus shackled, may be readily unshackled by depressing the spring' F, and causing the head D to turn in the recess H, until it can be withdrawn through the entrance to said recess.

It will be seen that my invention entirely obviat-es the necessity of passing between the cars to shackle or unshackle them, thus saving much time and labor, with the additional advantage of not endangering human life.

Having thus described my invention, what I claim is The car-coupler, consisting of the bar A,

provided with the spring J and recess H, the bar B provided with the recess I, and the rod C provided with the head D and bulb K,

combined to operate with the spring F and
