' FRIGIDAIRE CORPORATION, A CORPORATION OF DELAWARE REIFBIGERATING APPARATUS Application filed July 30,

This invention relates to refrigerating apparatus, particularly to devices such as hinges, latches, escutcheons, and the l ke Which are ordinarily associated with the doors of refrigerating cabinets.

It is among the objects of the invention to provide an improved construction of hinge or the like which is economical to manufacture, which has an attractive appearance and 10, which is stronger and more durable than devices of' this sort heretofore used.

It is another object of this invention to provide a hinge or similar device which may be attached tohighly finished or frangible surfaces without injuring the finish of the surface. It is also an object of this invention to provide a pressed metal hinge or similar device which is economical to manufacture and which has the rich, heavy appearance of cast metal devices of this character and a strength and durability superior to cast devices.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a preferred form of embodiment of the present invention is clearly shown.

In the drawings 7 Fig. 1 is a perspective view of a hinge; Fig. 2 is a View of a hinge partly in longitudinal section and partly in elevation, and Fig. 3 is a section on the line 33 of Fig. 1. Referring to the drawings, 10 indlcates a door of a refrigerating cabinet which 1s supported on a jamb 11 by hinges generally denoted by 12. The door includes a metal cover having a frangible finish thereon and formed to provide the front surface 13 and edge surface 14. The hinge chosen for illustration of the present invention has a butt member 15 attached to the jamb and a strap member 16 suitably pivoted to the butt member in the usual manner and attached to the door; For the sake of appearance it is desirable to have the strap member in contact with both surfaces of the door and to this end it is provided with an L-shaped edge which contacts with both surfaces.

metal having'an outer curved surface 20v which presents a rich and pleasing appearance and a fiat surface to be clamped against the door. The fiat surface has a large area which distributes the clamping force uniformly. over the contacting surface, which results in a low pressure being applied to the base or frangible surface. These hinges have been objectionable for the reason that in cases where the hinge is in contact with both the face and edge surface of the door, unless the strap member is made so massive as to be objectionable from the standpoint of cost and appearance, the strap member is particularly weak at the point opposite the corner 21 and frequently breaks at this point when the door is swung wide open and suddenly stopped by the hinge reaching the limit of its travel. I

I remedy the above defects by providing a hinge having a strap of pressed metal which on the outside may have an appearance identical with that of previously known cast hinges, the strap member being appropriately curved as shown in the sectional views. The curvature of the strap provides great strength and results in having the strap in contact with the surface of the door at its edges only. In order to provide great strength at the portion of the strap which passes around the corner of the door and also to provide an edge which will not injure the finish of the door surface, I provide a reenforcing rim or flange 22, integral with the strap and continuous thr'uout the length of the edge which contacts withthe door. This flangeis formed preferably by turning the edges of the strap in along its entire len th. Thus the strap has in effect an L-shaped e go, one leg of which contacts with the surface of the door and both legs of which are provided with a reenforcing and surface protecting bend, flange or rim. The fact that the rim is continuous around the corner makes an exceedingly strong hinge.

It has been found that the best results are obtained when the rim makes contact with the surface of the door at a very slight acute angle, preferably about 3.
