DESIGN FOR A KNUCKLE FOR CAR-COUPLINGS.

SPECIFICATION forming part of Design No. 33,750, dated December 18, 1900.

Application filed September 10, 1900. Serial No. 39,609- Term of patent 14 years.

To all whom it may UOII/CLI'III.

Be itknown that I, PHILLIP llIEN, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented and produced a new and original Design for a Knuckle for Oar-Couplers, of which the following is a specification, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

As shown in said drawings, Figure l is a top plan view of a knuckle embodying my design. Fig. 2 is a front elevation of the same. Fig. 3 is a rear elevation of the same. Fig. 4 is a side elevation of the same. Fig. 5 is a section taken on line 5 5 of Fig. at.

As shown in the drawings, a knuckle constructed in accordance with my design con sists of a casting or forging of metal comprising two main integral parts namely, the jaw A and the tail Bwhich extend at approxi mately right angles with each other. Said jaw is relatively broad vertically, as is also the tail at its point of union with said jaw; but the same tapers toward the rear end, where it is narrow vertically and broad horizontally. The jaw A is divided or cut horizontally at its central part with a relatively wide slot (1, as shown in Figs. 2, 3, 4, and 5. Said slot extends from the outer end of said jaw inwardly toa point in alinement with the inner face of the tail. The jaw is also provided in a familiar manner with a cylindric aperture a', passing vertically therethrongh transversely of said slot. The outer end of said jaw is rounded, as illustrated in Fig. 1. The outer surface of said jaw and tail at the apex of the angle formed thercbyis rounded, as shown in Figs. 1, 2, and 5, and on the opposite side therefrom or on the inner side of said angle said parts are cylindrically concave. A cylindric aperture 0, parallel with the aperture a, extends through the said knuckle, centrally thereof, at the point where said tail is united with said jaw. The sides of the knuckle are provided with cylindric recesses at the inner end of the jaw concentric with the aperture 0, providing parallel plane faces 0 c on the upper and lower sides of the knuckle. Said cylindric recesses are of such diameter as to cut through the outer surface of the jaw at points adjacent to the apex of the angle formed by the jaw and tail, thereby providing rearwardly-di rected shoulders c c on the upper and lower side of the jaw, at the rear end of the same. On the outer side thereof said shoulder, as clearly indicated in Fig.2,extends in a convexly-curved line the entire breadth of the jaw.

The tail 15 extends rearwardly from said jaw, and on the outer side thereof, intermediate of the aperture 0 and the rear extremity of said tail, is provided with a laterally and forwardly extending hook I), integral therewith. From the point of said hook the outer side of said tail curves rearwardly to its extremity.

The inner side of the tail, adjacent to the extremity thereof, is plane. Said surface is indicated by b and forms approximately right angles with the outer flatsurface of the jaw. Said tail at its rear end is provided with a rearwardly-directed relatively thin flange 1), the upper surface of which is continuous with the upper surface of the tail. The rear end of the tail is curved concentrically with the aperture 0. At the outer side of said tail, at the real-end thereof, beneath said rearwardlyprojecting flange b is a rearwardly-directed integral point or projection b (Shown in dotted lines in Fig. l and in fulllines in Fig.5.)

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

The design for a knuckle for car-couplers substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

PHILLIP HIEN.
