DOOR CLAMP Filed Dec. 12, 1936 ATTORN EY Patented Sept. 7, 1937' UNITED STATES PATENT OFFEQE DOOR CLAMP Application December 12, 1936, Serial No. 115,519

2 Claims.

This invention relates to improvements in clamps for doors and is particularly applicable to doors which are exposed to the elements, such as garage doors and the like.

It has been found, in practice, that no matter how well such doors may be originally constructed, their exposure to the elements eventually causes the parts of the doors to separate Where they are joined together.

It is an object of the invention to provide a clamp adapted to be secured to opposite edges of a door and having means for drawing the door edges together to restore and clamp the parts of the door to their original position.

A further object of the invention is to provide a device of the character described comprising essentially two clamp sections of simple construction and economical to manufacture, adapted to be readily secured to a door and adapted to clamp the parts of the door together in a simple, efiicient and rapid manner.

A further object of the invention is to provide a device of the character described having adadjustable means for drawing the door edges together to the exact degree required, from time to time.

These and other advantageous objects, which will later appear, are accomplished by the simple and practical construction and arrangement of parts hereinafter described and exhibited in the accompanying drawing, forming part hereof, and in which:

Fig. 1 represents a perspective view of a door having two clamps embodying my invention secured thereto,

Fig. 2 represents a perspective view of a clampembodying my invention, and

Fig. 3 represents an enlarged fragmentary sectional view taken on lines 3-3 of Fig. 1.

Fig. 4 represents an exploded fragmentary perspective view of a modified form of my invention,

and

Fig. 5 represents a fragmentary top plan view of the same parts shown in assembled position.

Referring to the drawing, the clamp of my invention is shown to comprise a pair of

sections

5, 6. Each section has an end I angularly directed and bent back upon itself to provide a lug 8 of the requisite thickness and strength. The other end of each section is angularly directed at 9 and then bent back at IU parallel to the section to provide a U-shaped end. The U-shaped ends of the clamp sections are adapted to be secured to opposite edges l2 of the door l3 by screws M or other suitable means. The lug 8 of section 6 is provided with an aperture l5 through which a bolt [6 freely passes and engages the threaded aperture 11 of lug B of section 5 (see Fig. 3). By manipulating the bolt Hi, the

sections

5 and 6 are brought together and the opposite edges of the door It are drawn together to the degree required to restore the door parts to their original position.

The clamp sections are provided with elongated slots l9 through which screws It or the like are passed for engagement with the door 53.

If it is desired to draw the clamp sections'further together, it is merely necessary to back up a few turns on the screws I8, and when the clamp bolt [6 has been manipulated to the desired degree (as indicated in dotted lines, Fig. 3) the screws l8 are again turned down.

In the modification shown in FigsA and 5, the clamp section 6 is provided. with a suitable bearing. 20 adapted to receive a hinge pin 23 carried by a similar bearing 22 formed on the plate 2%, said plate being preferably securedto the door casing 24.

By this arrangement the usual door hinges may be dispensed withthe section 6 and its bearing 29 constituting one-half of the hinge, the plate 2|, its bearing 22 and pin 23 constituting the other halfof the hinge. It will be obvious that this arrangement results in a substantial saving in cost of labor and material, when two clamps embodying this modification are secured to a door as shown in Fig. 1.

By the device described, the door edges may be minutely and accurately drawn together to restore the parts of the door to their original position and further adjustments may be readily made from time to time as required.

The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention, of which obviously embodiments may be constructed, including many modifications, without departing from the spirit and scope of the invention as set forth in the appended claims.

Having thus described my invention, what I claim as; new and desire to secure by Letters Patent, is:

1. A device of the character described comprising a pair of clamp sections adapted to be secured to a door, said clamp sections being provided with elongated slots through which screws are adapted to be passed, and being further provided with outwardly extending lugs, and means engageable with said lugs to draw the clamp sections together.

2. A device for bracing doors and the like, comprising a pair of bars, each of said bars havin one end thereof bent to provide a U-shape, and the other end thereof bent at right angles and then bent back upon itself to provide a lug, each of said bars having elongated slots through which screws can be passed, one of said lugs being threaded, and a threaded bolt passing through said lug for drawing the bars together.
