My invention relates to door hingesand more especially to door hinges wherein a door supported thereby may be opened to a position ofiering a minimum amount of obstruction to the opening in which the door is supported.

The usual door hinge, especially hinges of the butt type, does not permit a door to be swung completely out of the opening in which the door is mounted except upon a movement of 180. The general object of the present invention is to provide an arrangement for a door wherein the door'may be swung through a small are, or substantially 90, into position wherein the door does not obstruct the opening in which it is mounted.

Another object of the invention is'to provide an arrangement ofhinges suitable for supporting relatively heavy doors, such as those used for refrigerator rooms, etc.

Still another object of the invention is to provide an arrangement of hinges forrelatively heavy doors which will permit the doors to be opened with a minimum amount of effort.

To these and other ends, the invention consists in the novel features and combination of parts to be hereinafter described and claimed. 7

In the drawings,

Fig. 1 is a front elevation of a pair of doors having hinges mounted thereon, according to my invention; 7

Fig. 2 is a sectional view along line 22 of Fig. 1, but showing the doors in open position;

Fig. 3 is a sectional view along line 33 of Fig. 2; and

Fig. 4 is a sectional View along'line 44 of Fig. 2.

Referring to the drawings in which I have illustrated my invention by showing a preferred embodiment thereof, the reference numeral indicates, in general, an opening leading into a refrigerator room or the like, the opening 10 being closed by a pair of double doors 11 andt12 hingedly mounted at the opposite sides 13 and 14 of the opening 10.

In carrying out the invention I mount the doors 11 and 12 so that they swing about 1929. Serial no. 344,969.

amount at least equal to the thickness of the doors, rods 15 and 16 being fixedly received in face plates 17 and 18 mounted on ceiling or other support 19 and in face plates 20 and 21 mounted on floor or other suitable support 22. Preferably, the rods 15 and 16 are pro-' vided with threaded ends which are received inthreade'd openings in face plates 17, 18, 20 and21.

N ear the bottom edges of doors 11 and 12 hinge arms 23 and 24 are secured, as for eX- ample by means of sc-rews25, hinge arms 23 and 24 being pivotally mounted on rods 15 and 16, respectively, and supported from plates 20 and 21 by means of anti-friction bearings .26 and 27 which may be of any suitabletype herein being shown (Fig. 4) in the form of pairs of cups 28 and 29 between which are received rows of hardened balls 30 held in spaced relation by spacer plates 31.

Mounted near the upper ends of doors 11 and 12 are hinge arms 32 and 33, while at intermediate points on doors l1 and 12 are hinge arms 34 and 35, arms 23, 32 and 34 being pivotally received on rod 15, while arms 24, 33 and are pivotally received on rod 16. In order to take up any wear in arms 32, 33, 34 and 35 Where they are mounted on rods 15 and 16, each arm is provided with an adjustable part in the form of a screw 36 received in a threaded opening in the arm, and held against movement by lock nut 37. The hinge arms are freeto rotate on rods 15 and 16, the adjustable screws merely acting to take up play and to prevent the doors from sagging.

In operation, it will be readily underslood that the doors 11 and 12 may swing freely on rods 15 and '16, the arrangement of the latter, together with the hinge arms, spacing the doors apart a distance at least equal to the width of the opening 10 when the doors have been opened 90, as shown particularly in Fig. 2. It will thus be seen that I have provided an arrangement for pivotally support ing a door or doors for opening movement wherein the door or doors may be opened to the full WlCllll of the opening in which they are mounted when swung through a small arc.

While I have shown a preferred embodiment of my invention, it will be understood that it is not to be limited to all the details shown, but is capable of modification'and variation within the spirit of the invention and the scope of the appended claims.

What I claim is:

1. A door hinge including an upright rod extending lengthwise of the door, means at the ends of said rod for supporting the same from a ceiling and a floor, a plurality of hinge arms mounted on said rod for pivotal movement thereon, one of said hinge arms being mounted on the rod near the lower end thereof and bearing against the adjacent means for supporting the rod from the floor.

2. A door hinge including an upright rod extending lengthwise of the door disklike means at the ends of said rod for supporting the same from a ceiling and a floor a plurality of hinge arms mounted on said rod for pivotal movement thereon, one of said hinge arms being mounted on the rod near the lower end thereof and bearing against the adjacent means for supporting the rod from the floor.

In witness whereof, I have hereunto set my hand this 5th day of March, 1929.

CLAYTON L. PHILLIPS.
