PHILLIP HIEN, OF CHICAGO, ILLINOIS, ASSIGNOR TO DAVID S. WEGG, OF SAME PLACE.

DESIGN FOR A KNUCKLE FOR CAR-COUPLINGS.

SPECIFICATION forming part of Design No. 34,179, dated March 5, 1901.

Application filed December 24, 1900. Serial No. 40,991. Term of patent 14 years.

To all whom, it TIMI/y concern:

Be it known that I, PHILLIP HIEN, a citizen 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 Knuckles for Oar-Couplers, of which the following is a specification, reference being bad to the accompanying drawings, forming a part thereof.

As shown in the drawings, Figure 1 is a side elevation of a car-coupler knuckle embodying my design. Fig. 2 is a rear end elevation of the same. Fig. 3 is a side elevation of the same, taken on the side opposite that shown in Fig. 1. Fig. 4: is a top plan view of the same.

As shown in the drawings, a knuckle constructed in accordance with my design consists of a symmetrical casting or forging of metal having two main parts integral and extending approximately at right angles with each other. Said parts comprise the jaw, (indicated by A,) which is relatively broad, and the tail, (indicated by 13,) which at its point of union with the jaw A is also broad, but which tapers toward the rear, where the same is relatively narrow. The jaw A is divided or cleft horizontally at its central part, providing a relatively wide slot at, as shown in Figs. 1 and 2, which extends from the outer end thereof inwardly to a point in alinement with the inner face of the tail. The same is also provided at its outer ends with a cylindric aperture a, passing vertically therethrough transversely of said slot. The outer end of said knuckle is rounded cylindrically, as shown inFig. 2. The outer surface of said jaw and tail at the apex of the angle formed thereby is rounded, as shown in Figs. 3 and 4,-and on the opposite side therefrom, or the inner side of said angle, the said parts are cylindrically concave. A cylindric aperture 0, of approximately the same diameter as the aperture a, parallel therewith, extends through said knuckle centrally thereof at the line of union between the said tail B and the jaw A. The sides of the knuckle are provided with cylindric recesses at the inner end of the jaw A, concentrically with the aperture c at the inner end of the jaw, providing parallel plane faces a c on the upper and lower sides of the knuckle at the ends of the aperture 0. Said cylindric recesses are of such diameter as to cut through the walls of the knuckle at a point adjacent to the apex of the angle formed by the jaw and tail, thereby providing rearwardly-directed shoulders c c on the upper and lower sides of the jaw A and forming the rearward limit of the same. On the outer side thereof said shoulder, as clearly indicated in Fig. 3, extends in a convexly-curved line the entire breadth of the jaw A. Commencing on the outer side of said knuckle the said tail 13 extends rearwardly with a slight outward curvature at a point near the apex of the angle to correspond with the outward curvature of the jaw A on the opposite side of said apex. At a point intermediate of the aperture 0 and the rear extremity of said tail is provided on the outer side thereof a lug B,'parallel with said aperture and having its ends I) 1) extending upwardly and downwardly beyond the tail, as shown in Figs. 1, 2, and 3. The ends of said lug beyond said tail B are curved on the outer side thereof transversely of their length. On the inner side, projecting above and below said tail, the same are plane and approximately parallel with the line of direction of said tail. Between said lug B and the extremity of the tail on the outer side thereof the same tapers inwardly to near the extremity, and at the extremity of the same is provided with an integral lug b, directed laterally of said tail at approximately right angles therewith and oppositely from the jaw A. The rear extremity of said tail and the rear side of said lug b lie in one and the same plane parallel with the outer surface of the jaw A at its middle part. The inner side of the said tail, as before described, is inwardly curved adjacent to its point of junction with the jaw A, said curvature being parallel with the axis of the aperture cand extending to a point intermediate of the same and the extremity of said tail and approximately opposite the lug -B, at which point is provided anangular ridge or projection b extending transversely across the inner side of said tail parallel with the lug BZ Said tailpiece at the rear of the ridge b is plane to the extremity In testimony whereof I have signed my 1 thereof and inclines slightly inwardly with name to this specification in the presence of in respect to the line of direction of said tail. tWo subscribing Witnesses.

Having described my invention, What I 3 i T 5 claim as new, and desire to secure by Letters PHILLH HIEL' Patent, is WVitnesses:

The design for a knuckle for car-couplers C. W. HILLS, substantially as shown and described. 1 LOUIS J. DELSON.
