4Ulaims. (CI.'16 13 This invention relates to hinges, and more particularly to hinges of the concealed type, .the

present invention being particularly suitablefor use in mounting doors on automobile bodies or the like. A

In my copending application Serial No. 184,356,

filed January 11, 1938, I have disclosed a concealed hinge comprising a; stationary bracket member provided with a spherical socket or bear in ing in-which is mounted a ball formed on the movable element of the hinge. Ifhe stationary element of the hinge is concealedwithin the door frame and the movable element thereof is secured to the door andis arranged to bereceived within 1-3 a well or recess in the bracket member whenthe door is in closed position. certain cases it has been found advantageous to provide additional bearing support forthe movable element of the hinge which carries the door, and the primary 1O object of my-present invention is to provide improved hinge of the concealed type having a greater bearing support than that disclosed in my aforesaid eopending application. I More specifically, it is an-object of my present 25 invention to provide an-fimproved hinge as aforesaid which has suificien't bearing support for the? movable element thereof to satisfactorily carry] even a very heavy door without permitting it to sag in the frame. 30 Another object of my present invention is to provide an improved hinge of the type set forth which will stand up under long and continued use and which will at all times maintain the door is to provide an improved hinge, as above described, which can be attached in place easily and to which the door can be just as easily secured, or from which the door can be easily re- 40 moved.

A further object of my present invention is to provide an improved hinge of the concealed type which is simple, yet durable, in construction, which is highly efficient in use, which readily 5 lends itself to the requirements of economical quantity manufacture, and which is inexpensive.

in cost.

In accordance with my present invention, I form the hinge similarly to that disclosed in my 50 aforesaid application, that is, with a stationary supporting bracket having a socket formed at least partially on a sphere and which receives a correspondingly formed element on the. swingable member of the hinge, the socket acting as 5?- one bearing for the swingable member. -In addition,;I provide a pintle which extends through the socket and the element received therein,.so thatthe pintle, which is coaxial with the spherical portion of the socket, acts as an additional bearing for the swingable member. There is thus 5 provided a pair of concentric, radially spaced, bearings which solidly support the swingable member of the hinge. jfIhe novel features that I' considercharacteristic' of my invention are set forth with particul0:

larity in the appendednclaims. The invention itself, however, both as to its organization and method of operation, together with .additional objects and advantages thereof, will best be unders'tood from the following descriptionof sev- 15 Referring more in detail. to the drawing, and

particularlyito Figs-1' and 2, there" is shown a hinge comprising a' bracket member I formed with anoifsetportion 3 "which terminates at one ndfin'a ana11y;sp er1ea1 ball socket 5,,the entife'strii'cture being'a'rl integral umtwhich may be formed, for example, by drawing the material of the bracket between suitable dies. The offset portion 3 provides an elongated well or recess 1 in which is received an L-shaped member 9 having a ball H formed integrally thereon at one end of one of the arms of the L. The ball II is mounted in the socket 5 and the edge portion 5a' thereof is forced around the ball ll whereupon the completed socket 5 acts as a bearing for the ball H. A pintlel3 having its ends I5 headed over against the socket 5 extends through the socket 5 and the ball ll coaxially with the socket 5 and in a direction normal to the plane in which the swingable member 9 moves into and out of the recess I, as shown by the solid and the dotand-dash lines in Fig. 2. Thus, the pintle l3 acts as an inner bearing member for the swinging element 9 and the socket 5 acts as an outer bearing member therefor. Together, therefore, the two bearing'means 5 and [3 provide an eX- ceptionally strong bearing support for the element 9.

The offset portion 3 of the bracket member is inserted into a suitable recess in the door frame (not shown) and the bracket member I is secured to the frame by means of screws passing through elongated openings I! in the bracket member, the openings I! being elongated to permit adjustment of the hinge to its desired position. Thereafter, the threaded free end I!) of the swinging member 9 is inserted into a suitable opening 21 in a door 23 which is to be mounted in the door frame, and a pair of cooperating nuts 25 and lock washers 21 are tightened up, first rather loosely until the door is fitted to the frame, and

then very tightly to hold the door firmly in position. Usually, a pair of hinges is used for each will always remain in proper fitting relation with the frame. The modification of my invention shownin Figs. 3 and 4 is quite similar. to that previously.

described. In this modification, however, the socket 5 has the shape of a sphere on which two diametrically opposed fiat sides 512 have been formed, as by pressing these sides toward each other in parallel relation, and the ball I I is similarly formed to provide the fiat-sides l la which bear against the fiat sides5b. Also, the fiattened ball H is centrally bored on a diameter greater than that of the pintle l3 and a bronze or other suitable bushing 29 is placed within the bore for the reception of the pintle I3. As' in the modification of Figs. 1 and 2, that shown in Figs; 3 and 4 provides a doublebearing support for the swinging element 9, the two bearing means 5 and I3 being concentric, and in radially spaced relation, and the socket 5 constituting an integral part of the stationary bracket member.

Although I have shown and described but two embodiments of my present invention, itwill be obvious to those skilled in the art that many other modifications thereof are possible. I thereforedesire that my invention shall 'not be limited except insofar as is made necessary by the prior art and by the spirit-of the appended claims. I

I claim as my invention? 1. A hinge comprising a relatively stationary bracket member adapted tobe secured to one of a pair of cooperating members constituting. a door and frame, said bracket member having an offset portion formed with a bearing socket con-' stituted by at least a partial sphere, a relatively movable member adapted to be secured to the other of said pair of cooperating members and stituting an additional bearing for said element. door, and once the door has been thus fitted, it

2. A hinge comprising, in combination, a relatively stationary bracket member adapted to be secured to a door frame, said member being formed with an elongated recessed portion having a socket at one end thereof formed in the shape of at least a partial sphere and constituting a bearing, a relatively movable member adapted to be secured to a door and having an element thereon formed in a shape similar to that of said socket, said element being mounted in said socket for swinging movement of saidmovable member into and out of said recessed portion, and a pintle extending through said socket and said element, said pintle constituting an additional bearing for said element and being coaxial with said sphere.-
