Specification of Letters Patent.

Patented Feb. 16, 1915.

Application filed November 25, 1914. Serial No. 873,870.

To all whom it may concern:

Be it known that I, PETER CHRISTENSEN, a citizen of the United States, and a resident of Argenta, in the county of Pulaski and State of Arkansas, have made certain new and useful Improvements in Bracing Devices for Screen-Doors, of which the following is a specification.

My invention relates to improvements in bracing devices for screen doors or the like and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to provide a device which can be made at small cost and which will effectively brace the door without adding materially to the weight thereof.

A further object of my invention is to provide a device of the type described which may be adjusted to doors of different sizes since it is provided with means whereby the bracing device may be lengthened or shortened within limits.

A further object of my invention is to provide a device of the type described in which the bracing of the upper and lower portions of the door may be independently effected.

Other objects and advantages will appear in the following specification and the novel features of the device will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings forming part of this application in which- Figure 1 is a face view of a door provided with my improved bracing device, Fig. 2 is a similar view on an enlarged scale certain parts being broken away and others being shown in section, and Fig. 3 is an enlarged view along the line 3-3 of Fig. 2.

In carrying out my invention I make use of a screen door of the ordinary type having the side members 1, the bottom member 2, the top 3, and an intermediate cross member 4:. This forms the frame of the door and supports the netting 5.

The bracing device preferably includes a casting of the shape shown in the drawings. This consists of a rectangular body portion 6, which is provided with longitudinal bores 7 and 8 respectively, these bores being substantially parallel. In order to insure the engagement of the outer portions of the member 6 with the central cross member 1 I preferably provide recesses 6", as shown in Fig. 8.- As will be seen from the drawings both sides of this casting 6 are-made alike so that the device may be used either on one side or the other, thus obviating the necessity of facing it one particular way. The casting 6 is provided with an opening 9 through which a screw 10 may enter.

In conjunction with the member 6 I use the brace rods 10 and 11, both of these rods being provided at their endswith eyes such as those at 10 and 11 respectively and each rod being threaded at its opposite end as shown at l0 and 11 From the foregoing description of the various parts of the device the operation thereof may be readily understood.

In attaching the bracing device the threaded ends of the rods 10 and 11 are placed in the respective bores 7 and 8 of the casting 6, these rods being inserted from opposite sides, as clearly shown in the drawings. The ends of the rods containing the eyes are provided with screws 12 for fastening the rods to the upper and lower portions of the door. Nuts 13 are then screwed onto the ends of the rods and drawn up to the desired tension against the ends of the memher 6. The screw 10 is now inserted through the opening 9 and screwed into the cross member 4. This forms an effectual brace for the door so as to take up any sagging tendenc It will be observed that by tightening or loosening one of the nuts the upper or the lower portion of the door may have more or less tension put on it, independent of the other portion. It is well known that in some cases the upper portion of the frame needs bracing while the lower portion does not or vice versa, or again both portions may need tightening and this device provides for all contingencies. It is to be further noticed that this brace operates differently from an ordinary turnbuckle since it makes use of the intermediate cross member 4.

The device is adjustable between limits so that it is not necessary to make bracing devices of particular length to suit each door and the fact that the rods extend in opposite directions permits an adjustment of twice the length of the projecting portions of the rods beyond the tightening nuts.

The parts are few in number and are of comparatively light weight, "thus adding practically nothing to the weight of the door.

I claim:

1. The combination with a screen door frame having side members, a bottom member, a top member, and a cross member in termediate of said bottom and top members, of a bracing device having a portion secured to said intermediate cross member, and adjustable portions connected therewith for bracing the upper or lower portions of the door independently "of each other.

2. In a bracing device for screen doors, a body portion having parallel bores, an upper rod fixed at one end to the door frame and having its opposite end extending through one of said bores, a lower rod fixed to the lower portion of the door and having its outer end extending through the other of said bores, means for adjustably securing the ends of said rod to said body portion, said last named means comprising a nut arranged to be screwed on the ends of each rod, said nuts bearing on opposite ends of said body portion, and means for securing said body portion to the intermediate cross member of the door.

3. In a bracing device for screen doors, a body portion'havin'g parallel bores, an upper rod fixed at one end to the door frame and "having its opposite end extending through PETER CHRISTENSEN.
