GONOEALED H INGE.

a pl c t on filed. March 1, 1926. Serial No. 91,400.

This invention relates to concealed hinges and particularly'to hinges of this class employing two substantially similar sheet metal buttmembers, coupled together by one or more link members, and particularly to hinge bu ts of this class adapted to be mounted in cylindrical or substantially cy lindrical apertures in the stationary support and swinging member, respectively; and the object ,of'the invention is to construct the hinge butts from a sheet metal blank fashioned to form a channel portion which traverses the bone or aperturein which the butt is mounted, and toprovide at the outer end of said ,channel ,bqdy, laterally extending flanges fashioned to form closures for the apertures or sockets which the butts are mounted; a further object being to provide a hinge butt of the class described, which by virtue of the constriction employed, may be manufactured at a nominal cost and yet provide a strong and durable hinge butt con struction, an especially in the construction of small hinges such as used in cabinet work; a still further object being to provide means for reinforcing the butt and to provide channels therein for guiding the movable link or link members employed; and with these and other objects in view, the invention consists in a hinge butt vof the class and for the purpose specitied which is simple in construction, efficient in use, and which is constructed as hereinafter described and claimed.

The invention described and claimed herein is an improvement .on that shown and described in 'a prior application filed by me November 27, 1925, and bearing Serial No. 71,539, and is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are .designated by suitable reference characters in each of the views, and in Which:

Fig. 1 is an edge view of a stationary sup- .port "and swinging member showing my 1m" proved hinge mounted in connection there-v with.

2 is a partial section on the line 22 of Fig. 1.

the edge of ,each of which'is providedwith an aperture or socket 152 for' rciving tghe separate butts of my improved hinge .1 3. In the construction shown in Eig sfl {5615 inclusive, each ofthe butts isfa shioned from a sheet metal blank 14 ,sho'wn in' Fig. 310i the drawing, one side edge of the blank being cut out to form a recess 15, to form at the opposite sides of said recess, arc-Shaped portions 16 foldable ,onthe -171atright i angles ,to the longit nal plane ioli' the sheet. The blank Mus also folded on the lines 18 to bring the

side portions

19 and 20 thereof into parallel relation to form of theblank,

The s d hiembs and 2 a e pm ided on their inner and adjacent faces with are sha ed grooves 2.3 f rmed by Pressing t metal outwardlyin U or channel fashion as i seen at 241 in ig. 5 of {the drawing. The outwardly pressed channel ermanent also form ribs which aid strengtheningorreinforcin g the side members

Qor bearing plates

19 and 20 ofithe separate buttsof the hinge.

The grooves 23 ,open through" the inner or lower ends of the butts .as' 'lclearly seen in Figs. 2 and 3 of the drawing 1 facilitate the mounting of ,pins12 5 in said g QOVQs. The pins 25 'are mounted upon andcarried by the free end portions ,of links 26 substan- 7 'tially J-shaped in form, vsaid links being shown are in alternate arrangement; that is to say, the long arm of one link is movable in the channel or groove 23 of one butt, and the short arm thereof pivoted on the pin 28 in the other butt, and the next adjacent link is alternately arranged; that is to say, the short arm is pivoted in the first named butt and the long arm movable in the second' named but-t as is the common structure in invisible hinges of the class under consideration.

In Fig. 6 of the drawing, I have shown a slight modification, wherein the crosshead portion of the body is enlarged as seen at 30 to give a greater bearing for the butt in the socket or aperture 12; while the front or free edges of the side portions of the butt have outwardly turned and curved flanges 31 which rovide a greater bearing surface for the utt in the socket 12, and also serve to reinforce and strengthen the front edges of said side. portions. In this form of construction, I also substitute for the grooves 23 and arc-shaped ribs 24:, formed by said grooves, apertures 33 in the opposite side walls of the hinge butt, and in the same arrangement as the grooves 23, it being understood that the pins 25 of the links 26 operate in the apertures 33. Aside from the modified features above stated, the butt shown in Fig. 6 will be of the same construction as that shown in the other figures of the drawing. I

The

separate side ortions

19 and 20 of the butt are prefera ly provided at their inner edges with prongs 32 which are preferably placed laterally and adapted to be driven into the base of the sockets or apertures 12, as seen in Figs. 2 and 4 of the drawing. When the butts are mounted in position, the wings or flanges 16 form closures'for the sockets or apertures 12 as clear- 1y seen in Figs. 1 and 2 of the drawing, and preferably seat within said socket so that the outer faces of the parts 16 lie flush with the outer faces or edges of the stationary support and swinging

member

10 and 11. W'ith the type of hinge construction shown, it will be understood that the adjacent edges of the stationar support and swinging member may be brought into abutting relation by moving the swinging member into closed position, in which position, the links 26 are contained within the respective butts of the hinge, and the swinging member may be moved into a fully open position as seen in Flgs. 1 and 2 of the drawing;

By constructing the hinge butts in the manner herein shown and described, it will be apparent that a strong and durable butt may be produced in a simple, quick and economical manner, and with comparatively few bending, forming and other operations, whereby a hinge of the class described may be produced at a very nominal cost, and

especially hinges of this type for light duty such as for use in cabinets and the like.

While I have shown certain details of construction for carrying my invention into effect, it will be understood that various v changes in and modifications of the construction herein shown and described, may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages.
