W. R. BREWER HINGE Filed Nov. 25, 1927 Patented June 3, 1930 WILLIAM R. BREWER, 'OF DULUTH, MINNESOTA HINGE Application filed November 25, 1927. Serial No. 235,530.

This invention relates to combination door suspension means and has special reference to a door having an arcuate portion such asfound in automobiles or the like.

The principal object is to provide two unlike hinges for cooperative action in the support of such a door, and other objects and advantages of the invention will appear in the further description thereof.

Referring now to the acompanying, drawing, forming part of this application and wherein like reference characters indicate like parts:

Figure 1 is a plan view of the cooperative units in the uppermost .or straight portion of a door,

Figure 2 is a similar view of the hinge in the lowermost or curved portion of the door, this view being taken on the line 22, Figure 3;

Figure 3 is an elevation taken on the line 8-3 of Figure 2 showing in section the in terlocked pivotal connection of the cooperative parts of the hinge;

Figure t'is a section on the line 44, Figure 3; and

Figure 5 is a sectional view on the line 55 of Figure 1. j

The upper hinge as shown in Figures 1 and 5 comprises the major supporting arcuately shaped arm 1, pivoted within the door frame as at 2 and in the foor as at 3; the housing within the door for such pivotal support being indicated at 4 and the housing within the door frame 5. This arm is pivoted in opposite corners or diagonally within the combined housings as shown in Figure 1, and within the housing 5 in the door frame is mounted a link 6 which is pivotally connected as at 7 within a suitable hole in the arm 1 preferably adjacent the pivotal connection 2 thereof, while the opposite end thereof is pivotally and slidably supported as at 8 within the housing 5, that portion of the latter above and below the hub of the link 6 being slotted as at 9 for sliding purposes and the pivotal support or pin 8 of the link extending both above and below the hub of the links for engagment within the slots 9.

This link connection with the arm 1 is for the purpose of constantly biasing the door towards open position, and to provide such stress I provide the U-shaped spring member 10, one end of which is riveted or otherwise secured as at 11 to the side wall of the housing 5 in the door frame while the other I end is brought around arcuately and hooked back of the hub portion of the link about the pin 8 so that the pin with the hub is constantly being stressed towards the pivotal connection 2 in the arm 1 thereby tending to hold the door in open position as shown in dotted lines Figure 1.

The lower hinge for the door comprises two similarly shaped members indicated at 12 and 13, the former as shown in the door frame and the latter in the door, they being pivotally mounted adjacent the outermost edge of the door frame as at 14 with their opposite ends pivotally united as at 15 and closable within the housing. These connected ends of the members 12 and 13 are preferably accomplished by the latter being bifurcated and straddling the former as clearly shown in Figure 3 of the drawings. By this construction of lower hinge it is apparent that the opening of the door which is arcuate in shape may freely swing outwards from the door frame as clearly shown in dotted lines Figure 3 and it being desirable that the stile of the door frame overlap the door when closed as is customary in such doors; and both hinges being so constructed as to swing the door wholly free of the projecting stile when open.

From the foreging it is evident that I have devised a pair of cooperative door hinges which adequately support an arcuately shaped door of the character described and having simple means for biasing same in open position. I

Having thus described my invention, what I claim and desire to secure by Letters Patent, is v A blind hinge for pivotally uniting two members having abutting faces and opposed recesses one within each face, comprising a single major supporting element pivoted at its opposite ends one within each recess, a.

biasing link pivoted at one end to the major arm intermediate of its ends and at its opposite end slidably pivotally united within one of the recesses and biased against closed r relation of the hinged members by resilient means.

In testimony whereof I aflix my signature.

WILLIAM R. BREVER.
