SPECIFICATION forming part of Letters Patent No. 532,464, dated January 15, 1895.

Application filed June 22,1894.

To all whom it may concern.-

Be it known that I, ALBERT O. JACKSON, a citizen of the United States, residing in Waukegan, county of Lake, and State of Illinois, have invented certain new and useful Improvements in Door-Hinges, of which the following is a specification.

My invention relates todoor hinges, and the object of myimprovements in the same is to provide door hinges which, when the door is closed, shall be invisible, and which by use of a spring combined with the hinges in a way hereinafter described, will cause the door when open to remain stationary at any position where it may be placed. I attain this object by mechanism illustrated in the accompanying drawings, in which- Figure 1. is an elevation of a door and a wall, or partition, as the same appear when a door hung upon my improved hinges is closed. Fig. 2. is an elevation of such door standing open, showing the hinges secured in their respective positions in the door and the door-jamb. Fig. 3. is a detailed cross-section of the door-jamb, showing the hinges drawn out as they are when the door is open, as it is in Fig. 2. Fig. 4. is a detailed plan section of one of the spring hinges taken on the line 44 in Fig. 3, showing the hinge drawn out. Fig. 5. is a front elevation of one of said hinges, a part of its plate being broken away.

Like numerals refer to like parts throughout the several views.

Referring to the drawings, Fig. 1 shows that the door, 10, upon which my hinges are used, is hung at the edge of the door-jamb, 11, in the same manner as doors are now commonly hung. This door is represented as closed. It has been deemed necessary to introduce this view in order that the drawings may show how the closed door appears when hung upon my improved hinges; that is, the hinges are invisible. The top and bottom hinges in such doorare identical in construction. Each is made as follows: The hinge proper has the slots, 12and 13, made nearly through the whole length of its leaves, 14 and 15. At the outer end of the slot, 13, the lug, 16, is formed. This lug is placed in the metallic socket, 17, which has the lug, 18, formed near its inner end, so as to pass through the Serial No. 515,372. (No modal.)

slot, 13. The socket also has formed near its sides, the rims, 19, having holes in them for screws to pass through. The coiled spring, 20, is placed in the slot 13, between the said lugs. This socket is designed to be let into a mortise in the door-jamb and to be screwed to the door-jamb. It is made deep enough to allow the leaf, 15, to slide back and forth,

with lugs, 21%, at its inner end, having formed 1 in them apertures for screws to secure the socket to the door.

The door is hung upon these hinges, as above indicated, the hinges being secured to the door-jamb near its edge at the side from which it is desired the door shall open; that is, the door is placed as house-doors are usually placed. The socket, 21, is sunk into the door until flush therewith. Hence there is nothing to prevent the edge of the door from fitting closely against the side of the doorjamb and so the hinges will be invisible.

Having fully described my invention, what I claim as new therein, and desire to secure Letters Patent of the United States upon, is

1. A hinge having closed slots made lengthwise in its leaves, one of its leaves having a lug formed at its outer end; in combination, with a metal socket having a lug near its inner end designed to pass through the slot of said leaf, a metal socket having a lug formed with a screw hole therein, and located near the inner end of the socket, a plate to be screwed upon said socket, and coiled springs to be inserted in said slots, said sockets being suitably furnished with screw holes by which they may be screwed to the door-jamb and the door, after being let into mortises therein, substantially as and for the purpose specified.

2. Ahinge having the slots, 12 and 13, made m inserted in said slots, the rims, 19, formed near the sides of the socket, 17, having screw holes therein, the lug, 214;, formed. at the inner end of the socket, 21, with screw hole therein, a door-jamb and door, substantially as and for the purpose specified.

ALBERT O. JACKSON.
