FRANK ENNIS, OF SYRAOUSE, NEW YORK, ASSIGNOR TO E. C. STEARNS & OO., OF SAME PLACE.

SPRING-HINGE.

SPECIFICATION forming part of Letters Patent No. 495,966, dated April 25, 1893.

Application filed May 16, 1892. Serial No. 433,084. (No model.)

To all whom it may concern,.-

Be it known that I, FRANK ENNIS, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented new and useful Improvements in Spring-Hinges, of which the following is a specification.

This invention relates to that class of spring hinges which hold the door yieldingly in a closed position.

The object of my invention is to simplify the construction of the spring hinge and to provide a reliable support for the coil spring, so that the latter will always be retained in its proper position.

In the accompanying drawings, Figure 1 is a front elevation of Iny improved spring hinge. Fig. 2 is a sectional elevation of the same, the section being taken through the pintles. Figs. 3 and 4 are horizontal sections in lines x-m and y-y, Fig. 1. Fig. 5 is a front elevation of the leaves of the hinge-detached from each other. Fig. 6 is a perspective view of the core bar which retains the leaves and coil spring in place.

Like letters of reference refer to like parts in the several figures.

A B represent the leaves of the hinge, one of which is secured to the door and the other to the jamb or door frame in the usual Inanner. Each of the leaves is provided on one side with outwardly projecting lugs c c', the lugs of both leaves being pivotally connected. The lug c of each leaf is provided with an inwardly projecting pintle d and the lug c of the same leaf is provided with a socket or opening e which extends entirely through the same and is arranged axially in line with the pintle d. Both leaves of the hinge are exactly alike, and in connecting them to each other the pintle d of one leaf enters the socket in the other leaf from the outer side upon moving the leaves lengthwise upon each other.

F represents a core bar whereby the leaves are prevented from moving lengthwise upon each other in the direction of their pintles, after the two parts of the hinge have been connected together. The ends of this core bar are arranged in the inner ends ot' the sockets in the lugs c, and the bar is provided near its ends with collars f which bear against the i11- ner sides of the socket lugs c, thereby preventing both of these lugs from disengaging themselves from the pintles. Each of the socket lugs c is provided with a notch g in its side to permit of inserting the ends of the core bar into the sockets of these lugs.

H represents a coil spring whereby the door is yieldingly held in a closed position. This spring surrounds the core bar and bears with its end coils against annular shoulders h 011 the lugs c which shoulders form the contracted inner portions of these lugs. .The ends of the coil spring proj ect laterally and form arms h', which rest in seatsj in the leaves A B. The notches in the inner sides of the socket lugs c, through which the ends of the core bar are inserted, cause the end coils of the spring to be unsupported adjacent to the notches. For this reason the collars f, near the ends of the core bar, are made of the same diameter as the contracted inner portions ofthe socketlugsc, thereby forming uniform supports for the end coils of the spring. The core bar is also provided at its middle with a collar 7c which supports the central coils of the spring and assists in retaining the same in alignment.

I claim as my invention` The combination with the hinge leaves, each of which is provided with a socket lug having in its side a notch for the introduction of a core-bar, and a lug having a pintle,thepintle of one leaf engaging in the socket of the other leaf, of a core-bar arranged with its ends in the sockets of said lugs andprovided near its ends with collars which bear against the inner sides of the socket lugs, and a coil spring surrounding the socket lugs and core-bar and engaging with its ends against the leaves, substantially as set forth.

Witness my hand this 13th day of May, 1892.

FRANK ENNIS.
