UNITED STATES PATENT OFFICE.
I GEORGE M. JEWETT, OF UNIONVILLE, CONNECTICUT, ASSIGNOR TO THE OOWLES HARDWARE COMPANY, OF SAME PLACE.
IMPROVEMENT IN SPRING-HINGES.
Specification forming part of Letters Patent No. 221,964, dated November 25, 1879 application filed April 12, 1879.
To all whom it may concern:
Be it known that I, GEORGE M. JEWETT, of Unionville, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Spring- Hinges, (shown hereinafter as applied to gatehinges,) of which the following is a specification, reference being had to the accompany ing drawings, in which- Figure 1 is a view of the whole hinge. Fig. 2'is a detail view of a plate at each end of the spring, aboss upon it, and a bridge upon it, all hereinafter described.
The letters a a denote two plates, one of which is designed to be attached by common means to the gate and the other to the gate-' post. Each bears the journalpostb and the journal-post c. The rod (1 serves as a bearingshaft. Each of the journal-posts c bears a boss, 6, on which is set the helical springf. Each of the journal-posts 0 also bears the bridge g. By bridge I mean a piece practically rigid with post 0, and extending around or bridging the spring-that is, extending to the opposite side of the spring. The ends of the spring extend laterally in opposite directions, and, when the gate is in the closed position, bear each, first, on the end of a bridge, and, second, on a journal-post, b, that is on a leaf or wing extending from the journal-post.
When the gate is opened in one direction (that denoted by the upper arrow) the ends of the spring bear solely against the posts I), and by this pressure will close the gate when allowed to.
When the gate is opened in the opposite direction (that denoted by the lower arrow) the ends of the spring bear solely against the bridges g, and by this pressure will close the gate when allowed to.
.The posts 0, as a matter of detail, bear the plates h, on which the spring rests at its ends, and the bosses e e and bridges g g are set on and attached to these plates. By preference, these plates, bosses, and bridges are made in one piece separate from the journal-posts, as shown in Fig. 2this for convenience in casting, and to make one pattern serve the two purposes.
I claim as my invention- Plates 0, journal-posts b, journal-posts c, bearing-bridges g, shaft d, and spring f, with its ends bearing on bridge and journal-post, all combined to operate substantially as and for the purposes described.
GEO. M. JEWETT.
