Description
H. C. HART. SPRING HINGE.
Patented July l, 1890.
(Model.)
UNITED STATES PATENT OFFICE.
HENRY O. HART, OF DETROIT, MICHIGAN, ASSIGNOR TO THE VAN IVAGONER & WILLIAMS COMPANY, NEV YORK.-
SPRING-HINGE.
SPECIFICATION forming part of Letters Patent. No. 431,349, dated July 1, 1890.
. Application filed January 31, 1889. Serial No. 298,299. (Model.)
To all whom it may concern.:
Beit known that I, HENRY O. HART, of Detroit, inthe county of Wayne and State of Michigan, have invented a new and useful Im- 5 provement in Double-Acting Spring-Hinges,
of which the following is a specification.
My invention consists in an improvement in double-acting' spring-hinges, hereinafter fully described and claimed.
Io Figure l is a front elevation. Fig. 2 is a side elevation; Fig. 3, a cross-section on line a: c, Fig. l; Fig. 4., a perspective of the spring, and Fig. 5 a perspective of a hook forming the end of the spring, by which it connects with the leaf.
G and F represent the two leaves of a double-acting spring-hinge, the pintle-linebeing thrown forward from the plane of the leaves, as is usual in this form of hinge.
2o E represents a bow-spring of steel, whose ends are pivotally connected with the leaves G F ata point between said leaves and the pintlesline, as shown in Fig. 3, whereby the action of the spring E will hold the hinge closed, or, after opening a certain distance, will hold the hinge open, as shown in dotted lines, Fig. 3. The ends of the spring E may be formed into hooks to engage directly with the leaves; but it is usually easier to make 3o the hook of some softer metal than the spring and connect the ends of the spring ther ewith. Such a hook is represented in Fig. 5, in which a bar A has formed at its two ends the hooksGand carries three projecting lugs, the 3 5 end onesB B being on the saine side and the center one D being on the other side, so that the end of spring F. will lie between the lugs D B B and be held therein by the pressure of the spring. The hooks C C cngage with pins H H, formed on the leaves G F. The operation of this hinge is as follows,
reference being had particularly to Fig. 3: When the hinge is closed-that is, in theposi tion shown in full lines in Fig. S-the force of the spring E, acting on pins H, tends to draw said pins together, and, as they are located between the plane of the leaves and the pintle-line, holds the hinge closed. Nhen the hinge is opened, one of the pins H travels in a circle whose center is the pntle of the 5o hinge, and the distance between the pins H on the opposite leaves constantly increases until a straight line between said pins H cuts the pintle-line of the hinge. This is called the dead-point of the hinge, and at this 5 5 point the spring E has no eifective action. If the opening of the hinge be continued, as soon as the line between the two pins H passes the pintle-line the force of the springF. draws the pins H toward each other and holds the 6o hinge open, as shown in dotted lines in Fig. 3. It is evident that this construction permits the use of a continuous pintle instead of two short pintles.
That I claim as my invention, and desire to secure by Letters Patent, is-
1. In a double-actin g spring-hinge, the combination of two leaves having their pintleline outside of the plane of said leaves, and a bow-spring having its opposite ends pivotally 7o connected, respectively, with said leaves between the plane of the leaves and thc pintlcline, substantially as shown and described.
2. A hinge consisting of leaves F and G, a bar A, having projecting lugs B B D and hooks O, connected with parts of a hinge-leaf, and a bow-spring E, held by said lugs, substantially as described.
