UNITED STATES PATENT OEEICE.

WILLIAM F. BADING, OF GRAND HAVEN, MICHIGAN.

COMBINED SPRING AND LOCK HINGE. v

SPECIFICATION forming part of Letters Patent No. 765,372, dated July 19,- 1904.

Application filed December 3, 1903. Serial No. 183,546. (No model.)

To aU, whom, t 'may concern.'

Be it known that I, WILLIAM F. BADING, a citizen of the United States, residing at Grand Haven, in the county of Ottawa and State of Michigan, have invented a new and Improved Combined Spring and Lock Hinge, of which the following is a speciiication.

My invention relates to spring-hinges; and the objects of my improvement are to provide a hingev that will hold a door in either the closed or open positions, that will close the door when partially opened and then released, and that can be easily and cheaply constructed. I attain these objects by the construction illustrated in the accompanying drawings, in which- Figure 1 is a front view of the hinge in the position assumed when holding the door closed. Fig. 2 is a view of the hinge when holding the door open. Fig. 3 is an end view of the hinge in this position. Figs. 5 and 7 are details, and Figs. 4 and 6 are modifications.

Similar reference characters refer to like parts throughout the various views.

The .two leaves A and B of the hinge .are connected by the bolt or pin C, having a solid upper head D and the nut E on its lower end. The leaf A has lugs F and Gr, while the leaf B has lugs H and I. The lug H is provided with a tongue 7L, which enters the notches lo at the upper end of the grooves L in the collar K on the pin, as shown in Figs. 1 and 2. These grooves receive the upper end of the spiral spring M. The lower end of this spring enters the groove a of the collar N. This collar is provided with a tongue 0, which will enter into either of the notches c' or c" in the lug I of the leaf B. The jaws O on this collar engage the iiange P on the leaf A and prevent the collar from turning. Ordinarily the spring will be found sufficient for both closing the door and holding it either in the open or closed position-that is, for holding the tongue 0 in either of the notches e' or f1'. It may be desirable, however, to have a special spring for the latter purpose, and in such cases I provide the spring R inside of the coil of spring M, which spring R merely presses down'the collar N.

The torsion of the spring M may be adjustby the lugs O' of the collar N2, as shown in Fig. 6. The spring R may be used or omitted, as desired.

W hen the door is closed, the spring M or the two springs M and R will hold the tongue 0 of the collar N in the notch c', thus preventing any angular motion between collar N and lug I or between the two leaves of the hinge. By forcibly opening the door the incline of the tongue will be caused to ride up on the.

incline of the notch. If the door is carried far enough for the tongue 0 and notch c" to register, the tongue will be forced into this notch and the door held open until suiiicient force is brought to bear to force the tongue out of the notch. When the door is in a positionintermediate the open and closed positions, the springM will tend to close the door in the usual manner.

Having now explained my improvement, what I claim as my invention,-and desire to secure by Letters Patent, is-

l. In a spring-hinge, the combination of leaves having lugs, a pin connecting said lugs, a spring on said pin between said lugs, a collar on said pin at one end of said spring having a ratchet connection with the adjacent lug whereby the tension of said spring may be adjusted, and a second collar at the other end of the spring having a tongue to engage slots in the adjacent lug of one leaf, said collar having jaws to engage the other leaf.

2. In a spring-hinge, the combination of leaves having lugs, a pin connecting said lugs, a spring-on said pin between the lugs, a collar on said pin at one end of said spring having a ratchet connection with the adjacent lug whereby the tension of said spring may be adjusted, a second collar at the other end of the spring having a tongue to engage slots in the adjacent lug of one leaf said collar having jaws to slidably engage the other leaf, said spring tending to return the leaves vto normal position, and a second spring on said pin to press the tongue of said collar into the grooves in the adjacent lug and thereby hold the leaves in predetermined positions.

3. In a spring-hinge, the combination with the leaves adapted to be pivotally united, each of said leaves having tubular lugs or knuckles, of a pin connecting said lugs, two collars on said pin, a spring connecting said collars, one of said collars having a ratchet connection with a lug on one leaf, the second collar having a tongue to enter a notch in a second lug of said leaf when said leaves are flat and enter a second notch in said lug when said leaves are at an angle to each other, and means to prevent angular movement between said second collar and the second leaf of the hinge.

In testimony whereof I have signed my name to this specification in the presence of tworsubscribing Witnesses.
