HINGE.

SPECIFICATION forming part of Letters Patent No. 655,606, dated August 7, 1900. Application filedDecember 16,1899. Serial No. 740,572. (No model.)

To all whom it may concern.-

Be it known that I, HENRY R. CLARK, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Hinges, of which the following is a specification.

My invention relates to hinges, the object of the same being to produce a spring-hinge which may be used in any position and in which means are provided independent of the spring for preventing the separation of the two leaves when in use.

The invention consists of a hinge in which the two leaves are identical with each other, each being provided with two lugs, one of which has an inwardly-extending pintle thereon and the other a pintle eye or socket, the lug carrying the pintle being provided with a lateral projection adapted to engage a shoulder on the other leaf for limiting the outward movement of the hinge, and also provided with a recess forming an outwardlyeXtending tooth, in which recess fits a segmental flange or rib on the other part, which flange is notched at one end for the passage of said tooth therethrough for the purpose of connecting and disconnecting the leaves one with the other.

The invention also consists in certain features and details of construction and combinations of parts, which will be hereinafter more fully described and claimed.

In the drawings forming part of this specification, Figure l is a front elevation of my improved hinge. Fig. 2 is a top plan view of the same. Fig. 3 is a detail view of one ,of the leaves of the hinge. Fig. 4 is a horizontal section on the line to LU of Fig. 1, with the spring removed and showing the leaves open. Fig. 5 is a section on the same line with the leaves closed, showing the parts in position to be connected or disconnected.

Like reference-numerals indicatelike parts in the different views.

,Eoth of the leaves 1 of my improved hinge are exactly alike; but when the two are applied they are of course reversed in position with respect to each other. By constructing both leaves alike the same may be formed from the same pattern and economy in the manufacture of the hinge is thereby ob- 'with each other.

tained. Each 'of the leaves, as shown, is formed with two lugs 2 3, the lug 2 being provided with a pintle 4, having an ornamental head thereon. The lug 2 is also provided with a lateral projection 5 and with a recess or notch 6, providing a tooth 7 ,which extends out toward the pintle 4. The lug 3 is provided with a pintle-eye 8 and with a boss or hub 0, as clearly shown. It is further provided with a segmental flange or rib 10,having a notch 11 adjacent to one end thereof. A shoulder 12 is also formed on the lug 3 for a purpose which will presently appear. When the parts of the hinge are assembled, the opposite ends of the spring 13 fit upon the bosses or hubs 9 of the two hinge members, and the terminals of said spring bear against shoulders 14 on the lugs 3, so that said spring serves to maintain the two leaves of the hinge in the position in which they are shown in Figs. 1 and 2 of the drawings-that is, inline Then in this position, the lateral project-ion 5 on one leaf engages the shoulder 12 on the other, the engagement of which parts serves to limit the pivotal move ment of the two leaves in one direction. The flange or rib 10 of one member fits within the notchor recess 6 of the other during the operation of the device and prevents the separation of the two parts of the hinge. lVhen it is desired to connect or disconnect the parts, it is necessary to move the leaves to the position in which they are shown in Fig. 5 of the drawings, when the tooth 7 will register with the notch or cut-away portion 11 in the rib or flange 10 and said tooth is free to be moved in one direction or the other throng said. notch.

From the foregoing description it will be observed that according to my invention economy is obtained by making both parts of the hinge alike in that a single pattern may be employed for casting and that a further economyjs obtained in that no machine-work whatever is required on the hinge. It will also be observed that when the parts of the hinge are assembled and are in operative relation to each other they are prevented from separation by the engagement of the rib or flange 10 with the tooth or projection 7, which parts act independently of the spring. The

weight of the door or other part mounted on the hinge is also held away from the spring and the latter is free to exert its entire force in resisting the movement of the door or returning the same to its normal position. At the same time it it be desired to disconnect the two parts of the hinge at any time it is merely necessary to remove the spring and turn the two leaves to the position in which they are shown in Fig. 5 of the drawings, when the tooth 7 is free to pass through the notch 11. It is impossible for the two parts of the device to separate while in use and the hinge is practical without the use of the spring. In fact I may deem it advisable under some conditions to dispense with the spring altogether.

It will be observed that the pintle-eye 8 on the lug 3 has no lateral passage leading into it, but is closed on all sides. When the pintle 4- on the opposite leaf of the hinge is in said eye and the hinge is in its operative position, it is impossible for said pintle to be withdrawn from said eye by a lateral movement. This construction provides a much more satisfactory hinge, in that the danger of accidental separation is effectually removed.

Having now described myinvention, what I claim as new is-- 1. A hinge comprising two members identical with each other, but oppositely disposed when assembled, each of said members having lugs thereon, one of said lugs having a pintle, a lateral projection, and a recess or notch forming a tooth the said tooth being located between said lugs and the other of said lugs having a pintle-eye, a segmental rib or flange, a notch in said flange, and a shoulder, the pintle on each of said members extending toward the pintle-eye on the same member and fitting within the pintle-eye on the other of said members when the parts are assembled, the lateral projection on each of said members adapted to engage the shoulder on the other for limiting the pivotal movement of said members in one direction, the segmental rib or flange on each of said members fitting within the recess or notch on the other of said members, and the tooth formed by the recess on each of said members adapted to pass through the notch in the rib or flange on the other of said members, as and for the purpose set forth.

2. A spring-hinge comprising two members identical with each other, but oppositely disposed when assembled, each of said members having lugs thereon, one of said lugs having a pintle, a lateral projection, and a recess or notch forming a tooth the said tooth being located between the two lugs and the other of said lugs having a pintle-eye, a boss or hub, a segmental flange or rib, a notch in said flange or rib and a shoulder, the pintle and hub on each of said members extending toward each other, and the pintle on one of said members fitting within the pintle-eye on the other of said members when the parts are assembled, thelateral projection on each of said members adapted to engage the shoulder on the other for limiting the pivotal movement of said members in one direction, the segmental rib or flange on each of said members fitting within the recess or notch on the other of said members, and the tooth'formed by the recess on each of said members adapted to pass through the notch in the rib or flange on the other of said members, and an actuatingspring whose ends encircle the bosses or hubs on each of said members and whose terminals engage the shoulder formed, respectively, on said members, as and for the purpose setforth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

HENRY R. CLARK.
