HINGE.

SPECIFICATION forming part of Letters Patent No. 480,790, dated August 16, 1892.

Application filed November 28, 1891. Serial No. 413,390. (No model.)

T0 all whom it may concern:

Be it known that I, THOMAS TANGNEY, a citizen of the United States, residing at South Superior, in the county of Douglas and State of Visconsin, have invented certain new and useful Improvements in Hinges; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled initheart to which it appertains to make and use the same. My invention relates to hinges, and the object of same is to provide a hinge that is simple and practical in construction and 0peration and one which can be countersunk in the door-jamb or door, so that the door will iit closer than with the ordinary hinge, and when closed the hinge cannot be seen. I attain said object by a certain construction, combination, and arrangement of parts fully described in this specification and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the hinge closed. Fig. '2 is a similar view of the hinge open. Fig. 3 is a horizontal section. Fig. 4 is a detail view of the parts detached which compose the hinge. Fig. 5 shows a modification 0f my hinge.

Referring to the drawings, the letter A designates the j amb-plate of the hinge, which is provided upon the rear side thereof with the projecting box or hollow casing A. This casing or box when the hinge is applied to the door is preferably counter-sunk within the door-jamb. It is well to mention the fact, however, that said casing can be countersunk in the door, gate, rbc., and the hinge equally as well operated. It will be seen that the ends ct of the jambplate A project slightly beyond the sides or ends of the box A and that in each of said projecting ends there are screw-holes a', through which the screws are placed, which rigidly secure the same to the door or door-jamb. An opening a4 is provided in the face end of the casing for a purpose which will hereinafter more fully appear. In one of the sides of the boX A of the jamb-plate A there is a slot a2. The inner sides of the walls of the casing leading up to said slot a2 are beveled, so that the end b of the curved or V-shaped arm B of the plate B is adapted th'ereto and will fit therein, the same working freely in the opening d4. The wall a3 of the casing A adjacent to the slot a2 is curved inwardly and projects slightly beyond the side of the casing, so that the same is adapted to fit closely in the inner angular portion b2 of the curved arm B of the plate B, thereby performing the function of a stop and support for said arm when the hinge is opened to its full extent. The side b of the plate B in front of the point to which the curved arm B is secured is slightly concave, so that the same is adapted to work smoothly over the curved and outwardly-pro jecting wall a3 of the casing A. The plate B corresponds in length and width to the jamb-plate A and is likewise provided with similar screw-holes b3, whereby the saine may be secured to the door. The end Z9 of the angular or V-shaped arm B is provided with an orifice b4 and secured in the slot a2 by means of the journal-rod O, which is journaled through the orifice b4 and has bearings c c in the sides of the box A of the jambplate A. Such being the case, it is apparent that the plates A and B, respectively, are hinged or pivotally secured together, by virtue of which they are held in their normal positions and enabled to perform their respective functions.

As it is apparent that my invention is very practical and useful in operation, I deem it useless to further enlarge upon its merits.

1. In a hinge, the jamb-plate A, having the casing A', said casing being provided with an inwardly-beveled slot @2in one of the sides thereof, and an inwardly-curved and outwardly-projecting wall a3 adjacent said slot, in combination with the plate B, having the concaved portion 1;,.and the curved or V- shaped arm B', the end b of said arm being adapted to be journaled in the inwardly-beveled slot a2, whereby when the said plate B is swung outwardly the curved portion bzthereof will rest on the outwardly-projecting wall a3 of the casing, substantially as and for the purpose shown and described.

2. In a hinge, the combination, with a plate having upon one side thereof a curved or V- roo shaped arm, the jamb-plate A, havingthe In testimony whereof I aflx my signature 1n casing A', said casing being provided with an presence of two Witnesses. inwardly-beveled slot a2 in one of the sides thereof, and an inwardly-curved and out- 5 Wardly-projecting wall a3 adjacent said slot, Witnesses:

substantially as described, and for the pur- JAMES S. WALLACE, pose set forth. GEO. A. SHEDD.
