CONCEALED HINGE Dec. 14, 1937.

Filed Feb. 20, 1936 INVENTOR JOSEPH 5055 'ATToRN Patented Dec. 14, 1937 UNITED: STATES PATENT orrlca 14 Claim.

This invention relates to concealed hinges and particularly to hinges of this class which are commonly known as hinges of the hook arm type; and the object of the invention is to pro- 6 vide a hinge of the class specified, the hook arm of which consists of main and supplemental parts which are collectively and independently movable with respect to the butt housing, and whereby the supplemental part will permit a greater swinging movement of the door by reason of the independent movement of said part with respect to the main part; a further object being to provide an independent mounting of the supp emental hook arm part in connection with the butt housing or the @aced bearing plates thereof and to guide said mounting in the diil'erent movements of the supplemental part; a further object being to provide means for detachably coupling the supplemental hook arm part to the main hook arm part to provide quick and simple attachment and detachment of the door with respect to a door frame: a still further object being to provide a hinge of the class described, the separate parts of which are composed of sheet metal whereby the hinge may be constructed economically and thereby sold at a reasonable price; a still further object being to provide the supplemental hook arm part with a hood portion which partially conceals both main and supplemental hook arm parts, and at the same time, produces a neat and finished appearance to the hook arm structure of the hinge; and withfthese and other objects in view, the invention consists in a hinge of the class and'for the purpose specified, which is simple in construction, efliclent in use and which is constructed as-ihereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying' drawr ing forms a part, in which the separate parts'of I my improvement are designated by suitable refercharacters in each of the 'views,-an'd", in Tfwliich:v

' lthereior in dot and dash lines." I

- '2 is a transverse sectional viewroi the hingeshown in Fig. 1 in a partially ep npos1-' 3, A I g. 1 isa plan view of a hinge made accordgfing'jto my invention showing the same in closed F I: ;position and partially indicating the supports (Cl. 16-168) Fig. 3 with parts of the construction broken away.

The hinge forming the subject matter of my invention is of the concealed hook arm type and consists of a housing butt part 5 and a swinging 5 hook arm butt part 6 consisting, in the construction shown, of a main arm 1 and a supplemental arm 8. The housing butt part 5 in the construction shown consists of a facing plate 9 of sheet metal which has an angularly extending flange 10 I ii) at one side thereof.

Centrally oi the plate is a large opemng l I, upper and lower walls of which are provided with notches or cut-outs l2 adjacent the flanged side edge of said plate. Welded or otherwise secured 15 to the inner surface of the .plate 9 are substantially L-shaped upper and lower bearing plates l3, each consistingv of a part I arranged directly upon the plate 9 and secured thereto and an angularly extending as well as oifset plate l5. Op- 20 posed surfaces of the plates I 5 are arranged in alinement with the upper and lower edges of the apertures II as clearly indicated in Fig. 4 of the drawing.

In Fig; 1 of the drawing, I haveindicated in 25 dot and dash lines at iii the door frame in connection with which the butt 5 is mounted. At I1,

I have indicated in dot and dash lines a part of the door in connection with which the supplemental arm 8 01 the butt part 6 is mounted. It 0 will appear upon a consideration of Fig. 1 of the drawing that the bearing plates l5 extend into the stationary support l6. Apertures are formed in the offset corner lid of said plates to receive a pintle pin it employed for pivotally mounting 3 the main arm part i in connection with the butt housing. i Said part I is formed from a strip or sheet of metaLcne end of which is curled to form a substantially cylindrical bearing 20 in connection with which a headed pintle pin 2| is detach- 40 ably mounted.

The supplemental arm 8 is also formed from sheet metal and the end portion 22 of this am is substantially of the same width as the corresponding portion of the arm 1 but of different contour and the part 22 terminates at its free end in a curved knuckle 23 in which is secured a .pin 24 which projects beyond the upper and lower surfaces of the knuckle 23 to extend into and through bearing plates l5 or guide channels or I apertures 25 formed therein. The inner end por- Fig-3 is a transverse sectional'view substantially'on the line'3-3 of Fig. 4 'showingthe hinge inaiullyopen position; and, i

' Fig.1 is a face view of the hinge asshowniin' tion 25a of the apertures 25 are on an arc, the axis of which constitutes the center of the pin i8,

whereas the end portions 25b of the apertures 25 are on an arc, the axis of which is the center of the pin 2| when the latter is in the pofltion assumed when the main arm I is in its fully open position so as to permit the pin 24 to swing on the axis 2| in the movement of the supplemental arm 8 independent of the arm 1. -From a point beyond the corner 21 of said arm, the angularlyextendingpartflofthearmtisof greater width than'g'the end portion 22, and also of greater width than the arm I as may be seen at the right of Fig. 4 of the drawing. The free end of said part 28 is' cut out centrally as indicated at 24 to receive the cylindrical bearing 20 of the part I.

At opposite sides of the cut-out 28, or in other words, above and below said cut-out, the ends of the part 2 are curled to form pintle bearings 29 arranged directly above and below the bearing 24 and through which the headed pin 2| passes so as to provide the hinge mounting between the main and supplemental arms I and 4 to provide the independent swinging movement of the supplemental arm 8 from the position shown in Fig. 2 to the position shown in Fig. 3 and vice versa in the opening and closing movement of the 1 1 8 I preferably employ anti-frictional sleeves on the protruding ends of the pin 24 to relieve the frictional engagement upon the surfaces of the apertures 25. It will be understood that the outer end'portion of the ends 25b of said aper- 1 tures extend through the bearing plates and register with the notches or recesses l2 in the upper and lower walls of the plate 9 so that when the pin 2| is removed, the pin 24 including the bearings 30 thereon may be drawn outwardly through the notches l2. It will appear, however, that when the parts are assembled, the side walls |2a of the notches I2 act as stops limiting further outward movement of the arm I when the arms 1 and 4 are coupled together by the pins 2|.

I also preferably employ a shell or hood portion 2| for concealing or partially concealing the arms I and 8 as well as to reinforce and strengthen the arm structure the hood portion 3| where it abuts the arm 8 being welded or otherwise secured thereto. This'hood consists of a curved wall portion 42 which is of a contour different from that of the part 22 upon which it is arranged. This wall terminates at one end adjacent the corner 21 and at its other end in a part 42 which extends around the bearing or knuckle 23 as clearly seen in Fig. 2 of the drawing. The upper and lower edges of the hood 3| are extended to form top and bottomcover plates 24 which are of the same contour. These plates extend over the upper and lower edges of the arms I and I as clearly seen in Figs. 1 and 3 of the drawing. The pin 24 passes through said top and bottom plates 34 where they are arranged outwardly of the upper and lower surfaces of the knuckle 22. The end portion 24a of the plates 44 are arrangedangularlytotheinnersurfacesofthepart 26 of the arm 8 and terminate short of the bearingsuasmaybeseeninFigilofthedraw- The design or curvature of the hook arms may be varied to suit the different installation requirements, the butt housing being also fashioned to suit these requirements and also to give the desired throw or swing of the'door. This is also true of the form and guidance of the supplemental hook arm which is movable independently of the main arm to give the added door throw. The disclosure in the accompany ng drawing is only illustrative of one method of carrying my invention into effect.

In the accompanying drawing, when the butt parts 5 and 6 are in closed position, the arms I and l are in their substantially nested position one within the other and within the hood 4|.

The pin 24 is disposed at the inner end of the parts 25a of the apertures 25. In the operation of opening the door, the arms I and 4 will mainabove operation, or, in other words, in closing the door, the arm 8 first moves from the position shown in Fig. 3 to the position shown in Fig. 2, and then, both arms I and 8 swing inwardly to return to the position shown in Fig. 1.

The plate portion 26 of the arm I of the hinge will be fashioned to facilitate attachment to a door by screws, riveting, welding or otherwise. By reason of the detachable pintle 2|, this attachment to the door may be more or less permanent because of the detachable mounting of the door including the arm 8 with respect to the arm I and the butt 5. The plate 9 including the parts l4 of the L-shaped bearing plates I; may be fashioned in any desired manner for attachment to thedoor' frame by screws, bolts or the like.

My improved hinge is designed primarily for use as a'hinge for-motor vehicles but will have its usefulness in any other type of door hanging, especially where the use of concealed hinges is desirable. By constructing the several parts of the hinge from sheet metal, the same may be produced at a very nominal cost and at the same time, a strong and durable hinge is provided.
