UNITED :STAT-Es Parnu; onirica. JAMEsMAGNUSEN, or CHICAGO, ILLiuois. n I

Be it known that I, JAMESA MAGNUSEN, a

citizen of the United States of America, and c resident of Chicago,`Cook county, Illinois, have invented a certain new and useful Improvement in Hinges, of which the follow- My invention relates to improvements in hinges, and has for its object the production of a device whereby a closed door cannot be removed by withdrawing the pins from the hinges.

A further Objectis the production of a device that willl furnish a positiveflock, and

prevent lateral movement of the leaves ofl the hinge when in closed position.

A further object 1s the production of a de- 4vice that may be cheaply constructed.

These objects are attained by my device,y embodiments of which are illustrated in the accompanying drawings, in whichy Figure 1 represents a plan View of my device. Fig. 2 represents a sectional view lon the line 4 4 of Fig. 1. Fig. 3 represents a plan vieu' of a modification of my device. Fig. 4 represents a sectional view on the line o o of Fig. a. I j

Like letters of reference indicate like parts in the several figures of the drawings. V

Referring now to the drawings, 8 repre` sents a butt or hinge vcomprising leaves 114-12 represent ordinary l apertured knuckles on the leaves; a pin 13 passes through the openings in the knuckles, holding the lea-ves in operative relation one with the other. The inner face of the leaf 9 is provided with an inwardly projecting ear or lng 16, adapted to fit within an opening 15 in the opposite leaf. This opening is made slightl larger than the projection in order that tie e211 16 may readily enter vtherein when the hinge is closed.I This ear is' pref erably a portion of the hinge itself punched out and turned at right angles to the hinge.

In Figs. 3 and 4', the projecting portion 17, on the leaf 9 is formed by pressing a portion ofthe hinge itself inwardly while a cor-` responding depression 18 is 4formed in the. 'opposite leaf, the projecting vportion 17 ttlng closely within the indentation 18 of the opposite leaf when the hinge is closed.

Whenthe hinge is of the ordinary ty e,

I a `locked door may be lreadily forced from t e inside by withdrawing the pins from the 'T11 .hinges and prying the door inwardly. The

lock on the door does not serve to hold the door in place against a movement .of this kind, as it is only necessary to swing the door inwardly a distance of an inch or so on a radius of a circle, with the lock as a center. There is always suiiicient play in locksto permit this being done. The bolt may then be pulled out of the lock and an entrance effected to the room vor cabinet.k By the use of my improved device, however, the moment the door is closed, the inwardly projecting.. v portion on one leaf of the hinge tits within the opening or depression in the other leaf,

`preventing lateral displacement of the members when the pin is removed. Of course, this presupposes the fact that the doors lit close y within 'the casing. This is almostinvariably the case, soit is fairly safe to say that my device will, in nearly every case,

prevent the opening ofdoors when the hinge pins are removed.

The construct-ion of my device is extremely simple. Projections may be formed on one leaf and a hole punched through the other, adapted to register one with the other when the leaves are in closed position. The jection may be formed integral with the leaf itself by punching out three sides of the iece and turning an ear inwardly, as shown 1n Fig. 5; or, as shown in Fig. 4, a portion of one o f the leaves'may be pressed inwardly forming a protuberance, adapted to tit within va corresponding indentation formed in the opposite leaf.

` It will thus be seen that the hinge may. be cheaplymanufactured, and at the same time Abe practically irremovable when the door is closed. The device is especially applicable to box cases, cupboards, wardrobes, etc., as well asdoors communicating between apartments.

I claim:

As a new article of manufacture, a hinge comprising a pair of knuckled leaf members, a pin adapte to secure said members .to-

ether, an ear punched from and extending linwardly. from the face of one of said leaves,

and adapted to enterA within anv opening formed in the opposite leaf.

Illinois this 12th day of October, 1907.
