HINGE.

Specification of Letters Patent.

Patented June 1111, 11918.

Application filed September 20, 1917. Serial No. 192,263.

To all whom it may concern:

Be it known that 1, JOHN DIANovsznr, Sn, a citizen of the United States, and. a resident of the city of 'Passaic, county of Passaic, and State of New Jersey, have invcnted a new and useful Improvement in does not show when the hinged member is closed. Hinges of this-type as heretofore Constructed are rather complicated, have a multiplicity of parts and are rather expensive to manufacture. The object of my invention is to simplify hinges of this type and produce an invisible hinge which can be readily applied to adjacent parts, as for instance to a door and a door amb, a table leaf and a table or the like and in which the hinged butts or plates are made so that they can not only be easily applied but will be firmly anchored in the mortise in which they are secured. My invention also is intended to give to the hinged butts or plates such a shape as will facilitate the pivoting of the movable parts therein and my invention is further intended to simplify the link and leaf connection between the hinged plates or butts to the end that a simple, strong and reliablehinge may be produced.

Reference is to be had to the accompanying drawing forming a part of this specification in which similar reference characters refer to similar parts throughout the several views. I

Figure 1 is a perspective view of my improved hinge showing its application;

h Fig. 2 is a perspective detail view of the mge;

Fig. 3 is an enlarged detail sectional view showing the hinge in open position; and

Fig. 4. is a similar view showing the hinge in closed position.

The hinge has two opposed butts or plates 10 which are generally flat, preferably rounded at the ends and these are applied in the usual manner, that is, by countersinking to the opposed members 11 and 12, which are connectedby the hinge so that when open they will assume the position shown in Figs. 1 and 3. When closed, they will assume the position shown in Fi 4. Each plate 10 is provided with a poc et 13 preferably of a;

generally rectangular shape and preferably open on two of its sides, although this is not essential, and the pocket is stifi'ened' by a rib 14 there being a rib on opposite sides of the pocket and extending at right angles to the plate 10, so that when the plate 10 and pocket 13 are inserted in the mortise cut to receive them the rib or flange 14 will serve to anchor the hinged plate as well as to stiffen the pocket 13. If desired, this rib or ange 14: can be extended across the back of the pocket 14, as shown by dotted'lines at 14 in Fig. 2.

The plates 10 are provided with the usual screw holes 15 to receive the fastening screws 16 bywhich they are secured to the parts 1 1 and 12 and on the back each plate 10 is reduced near one edge as shown at 17, to provide for .placing the pivot pin 18 convenientl through the pocket walls and to enable tl ie pin to be placed close to the outer extremity of the pocket, so that the members connecting with the said pivot can swing out free and clear and allow the hinge a wide and free radius of action as will presently appear. Pivot pins 18 carry the short arms 19, 19" of the similar leaf members 20 and 20 which are exactly alike but are arranged alternately in opposed directions. That is, the members are lefts and rights. Each member 20, 20* is in the form of a double elbow lever having the short arms above referred to and the main elbows of the leaf members 20 and 20 coincide as shown clearly in Figs. 3 and 4: and are pivoted together by pin 21. By reference to Fig. 4, it will be seen clearly that the short bent arm of one member 20, 20 connects with the pivot 18 near the outer-extremity of th pocket 13 while the lon arm of the said member projects well into t e opposed pocket 13 where it is pivoted as shown at 22 to a link 23 and the latter swings freely in the pocket and is pivoted therein as shown at 24eat a point behind the pivot pin 18. Attention is called to the fact that the walls of the pockets are left thin so that the holes for the pivots 24; can be punched therethrough. Usually in hinges of this kind the butt plates are cast and the pivot holes have to be drilled through the pocket wall, but in the form of structure shown the pockets and butt plates can be stamped out and therefore more cheaply made. There are a series of members 20,20 and corresponding links 23 as many of said members being used as may be desirable, and it will be readily seen that Mill the number will depend largely on the strength required of the hinge. It will be seen that there are only two members connecting the opposed butts or plates 10 in each hinge element, that is the link 23 and the elbow leaf 20 or 20 and as before stated as many of these elements can be used as is necessary. When the parts 11 and 12 are arranged edge to edge the elements 20 and 23 close into the pockets 13, the links 23. swinging backward into the pockets and the long arms of the members 20, 20 straighten. ing out and bringing in the pivot pin 21; while, when the hinge is open the links 23 swing forward and the main elbows of the members 20, 20* together with the pin 21 move outward to the position shown in Fig. 3.

With this construction it will be seen that I produce a simple hinge which can be cheaply made, easily applied which has few moving parts, and which 1s unusually strong fora hinge of this character.

It will be seen that the butt plate 10 pocket 13 and rib 14 can be either cast or stamped out as desired.

I claim:

A hinge of the kind described comprising opposed butt plates having thin walled pockets with plain interior surfaces, the butt plates being also thinned near one edge and near the open side of the pockets, 3, plurality of alternately arranged double elbow levers connecting the butt plates with the main arms of the levers arranged at sharp angles to each' other and with their main elbows pivoted together opposite the meeting faces of the butt plates, each elbow lever having a short sharply bent arm near one end hun on a fixed pivot in one of the aforesaid poc ets near the front part and in alinement with the thinned portion of the corresponding butt plate, the long arm of said lever projecting into the opposite pocket, and links pivoted in the pockets behind the elbow levers and pivotally connected with the long arms of said levers.
