SPRING-HINGE.

T f/,ZZ whom ff may(fo/tecra: l bushing f/ being' provided with a screw- Be it known that I, HARRYJ. VALENTINE, a i threaded boss g2 and the lower bushing with 5o citizen ot' the United States, residing at Clcvea similar boss la. iVithin the upper and lower land, in the county of Cuyahoga and State of knuckles t' j, respectively, of the intermediate Ohio, have invented certain new and useful member or web a are plugs or bushings lmprovements in Spring-Hinges, of which the respectively.

The transverse Referring' to the drawings, the hinge commetallic strips formed into the knuckles jnot prises mainly an intermediate web or mcmonly form the knuckles, but transverse rein- V ber a between the two leaves Z) c, the cylinforcing and ornamental bands on the interdrical casings d, the pintles e, and the knobs mediate member a. The leaves c, provided j'. Each leaf c is provided with an upper with the knuckles .r/ are in like manner reknuckle and with a lower knuckle t, which intorced and ornamented by transverse strips knuckles are substantially cylindrical and ret, which are bent around both faces of each spectively receive plugs or bushings g z, the of said leaves and formed into said knuckles,

the portions of the strips s s in contact with the said leaves being suitably secured thereto. It will be seen that each of the transverse reinforcing-strips is made of substantially, if not of, the same width from end to end and that the two side portions of each bent-up stripthe only portions besides the knucklestraddle the leaf transversely thereof from the knuckle and lie in substantially parallel planes IO with the leaf, so that the ends of the leaves are uncovered.

As is well known, in this class of hinges the lower ends of the torsion-springs are anchored-that is to say, they are fixed against I5 turning--while the upper ends thereof are turned by means of capstans-such as o, be fore mentioned-these capstans being provided with a series of sockets 02 to receive a securing-pin, such as p, which projects from 2O the capstan and engages with the corresponding leaf. In the present invention riveting of the bushing, plug, or core inside the knuckles j is dispensed with. Instead advantage is taken of the fact that by using a metallic 2 5 strip to form the knuckles 7' recesses, such as q, are left at each edge of the intermediate web or member ct, which recesses are located to one side of the knuckles. rIhe bushings or plugs Z are therefore formed irregular in contour or have a side projection or nose r, which sets into the recess q, thus preventing the turning of the said bushing or plug. The

lower ends of the torsion-springs being thus prevented from turning, tension may be ap- 3 5 plied to the springs by turning the capstans 0. When the door is opened in either direction, the appropriate leaf acts on the straining or tension pin p, thus placing the spring under greater tension, the reaction of which is suflicient to close the door when released.

I-Iaving thus described my invention and without limiting myself to details, what I claim as newV therein, and desire to secure by Letters Patent, is;

l. In a spring-hingathe leaves, an intermediate member or web, and strips, formed with knuckles and secured transversely thereon at some distance from the ends of the said member, substantially as described.

2. In aspring-hinge, the combination of the intermediate member, leaves, transverse strips on the said member and leaves formed with cylindrical knuckles, and pintles passing through the knuckles, substantially as described.

3. In a spring-hinge, the combination of a knuckle member, in which a recess is located at one side of a knuckle, a bushing or plug substantially filling said knuckle and of irregular shape to provide a nose or projection 6C to engage said recess to prevent turning of the bushing, a spring connected at one end with said bushing, a leaf or second knuckle member, a pintle passing through the knuckles and bushing, said second knuckle mem- 6, ber being subjected to the action of the other end of said spring, and a spring and pintle casing.

In testimony whereof I have signed this specification in the presence of two subscrib- 7 ing witnesses.

HARRY J. VALENTINE.
