HINGE.

Application filed November 26, 1915.

To all whom it may concern Be it known that I, CHARLES J. Soss, a

citizen of the United States, residing at New.

York, county and State of New York, have invented certain new and useful Improvements in Hinges, of which the following is a full, clear, and exact description.

This invention relates to what are known as concealed or disappearing hinges, particularly those of the so-called hook type, and its chief object is to improve such hinges in the direction of strength and at the same time cheapness of manufacture. To this and other ends the invention consists in the novel features of construction and combination of elements hereinafter described.

One form of the invention is illustrated in the accompanying drawing, in which Figure 1 shows my improved hook-memher in perspective, mounted on the door frame. Fig. 2 is a plan view of the sheetmetal blank from which the hook-member is made by bending and pressing, Jreferably in suitable dies. Fig. 3 is a central cross section of the hook-member. Fig. 4 is a plan view of a filling piece that may be used in the hook. Fig. 5 is a perspective View of the hook-member (with a portion broken away) as used in the hinge.

My improved hook-member is made from a flat blank of sheet-metal, preferably of the general shape illustrated in Fig. 2, comprising a body portion 10 of rectangular form, a lateral extension or tongue 11, and oppositely extending arms 12 substantially parallel to the body portion 10 and having their ends widened as shown. By means of suitable dies or other tools (not shown), the two arms and the neck are bent at right angles to the plane of the body 10, about along the center line of the neck, indicated by the dotted line 18, the bend reaching substantially to the narrower portion 1% of the neck. Holes are also punched in the ends of the arms and in the body portion, as indicated by the dotted circles in Fig. 2; the holes in the body portion being countersunk to receive the heads of screws (as 15, Fig. 1) by which the device is fastened to the inner face of the door, or the door frame, 16. At

the juncture of the neck 11 and body 10 the metal is corrugated or similarly shaped, for example bulged as shown at 17, Figs. 1 and 3, to give the parts the strength necessary to withstand the bending stresses (sometimes very powerful) to which the hook is subjected in use.

In bending the arms and neck as described they may be bent until their inner surfaces are in contact, but to give the resulting hook greater thickness without using sheet-metal of unnecessarily heavy gage for the blank I prefer to employ a filling or spacing piece, as 18, Fig. 41:, clamped firmly between the extremities of the arms as shown in Fig. 1, the piece mentioned being of the same size and shape as said extremities and having a hole 19 to register with the holes 20 in the arms.

As part of the hinge the hook is used as in Fig. 5. Here, 21 designates a U-shaped socket, formed, say, by bending a metal strip 22, and intended to be fitted into a mortise in the edge of the door or door frame, not shown. The hook and the socket are pivoted together by a pivot 23, extending through the hole 20, Fig. 1, in the end of the hook. It will therefore be seen that parts can swing apart relatively to each other, the hook in the direction of the arrow a and the socket member in the direction of arrow 6.

Constructed as described, the device is exceedingly strong, in fact strong enough to withstand much heavier stresses than are met with in the normal use of the hinge, and is also cheaper to manufacture than any other with which I am familiar.

It is to be understood that the invention is not limited to the specific form herein illustrated and described, but is capable of various embodiments without departure from its spirit.

I claim:

1. In a hinge of the type described, ahookmember formed of a one-piece sheet-metal blank having a body-portion and a lateral neck provided at its outer end with oppositely extending arms, the neck and arms being bent centrally into substantially parallel planes at right angles to the plane of the body-portion and the sheet-metal at the juncture of the neck and body-portion being bulged to strengthen the member thereat.

2. Int hinge of the type described, a

5 hook-member formed of a one-piece sheetmetal blank having a body-portion and a lateral neck provided at its outer end with oppositely extending arms, the neck and Copies of this patent may be obtained for five cents each, by addressing the signature.
