Rundle, Palmyra, Wis. Application November 5, 1936, Serial No. 109,274 1 Claim. (Cl. 20-38) This invention appertains to doors and other letter A generally indicates my improved anti-sag closures, and more speci?cally to an anti-sag de vice therefor. Doors have a tendency to sag at their outer lower corners, which renders the same dif?cult to open and close. This is particularly true of doors of a heavy type. It is, therefore, one of the salient objects of my invention to provide a device which can be 10 easily and quickly applied to a door of any type, such as a screen door or a wooden door, and which will effectively prevent a door from sagging at its lower outer corner, and which will permit the taking up of the sag in a door, should the same be already out of line. Another salient object of my invention is to provide an anti-sag device for doors embodying a ?at metal strip adapted to extend diagonally across a door from its lower corner toward the inner edge of the door, with means for adjust ably connecting the strip to a bracket connected with the door adjacent to said inner edge. A further important object of my invention is the provision of novel means for forming the up 25 per end of the metal strip for receiving said ad justing device, whereby the strip will be effectively strengthened to prevent breakage or the bending thereof incident to the operation of the take-up appliance. 30 A still further object of my invention is to provide an improved attachment of the above character for doors, which will be durable and e?icient in use, one that will be simple and easy to'manufacture, and one which can be placed 35 upon the market at a reasonable cost. With these and other objects in view the in vention consists in the novel construction, ar rangement, and formation of parts, as will be hereinafter more speci?cally described, claimed, 40 and illustrated in the accompanying drawing, in which drawing: Figure 1 is a front elevation of a door showing my improved appliance connected therewith, the casing of the take-up mechanism being shown re 45 moved. Figure 2 is a section through the door taken on the line 2-2 of Figure 1, looking in the di rection of the arrows toward the anti-sag device, the casing for the take-up appliance being shown 50 in section. Figure 3 is an enlarged detail fragmentary view showing the casing in position. Referring to the drawing in detail, wherein similar reference characters designate corre 55 sponding parts throughout the several views, the device for a door D. The door D forms no part of the present inven tion and can be of any size or character. The door is connected by means of hinges 5 along one edge with the door frame 6. The anti-sag device A comprises an elongated ?at strip 1 formed from metal of the desired gauge, and this strip is adapted to be secured to the door by means of suitable fastening elements, 10 such as screws 8. The strap extends diagonally across the door from the lower outer corner there of toward the inner edge of the door. The upper end of the metal strip- or strap 1 is bent laterally at right angles and then back upon itself to form ll an ear 9. The bent portion of the metal is con tinued along the outer face of the strip or strap for a short distance and can be spot-welded to the body portion of the strip or secured thereto by any desired type of fastening element. The device also includes a bracket Ill, which is preferably secured by means of fastening ele ments II to the inner rail of the door. The bracket I 0 is also formed from sheet metal and is of a substantially U-shape, having outwardly extending feet through which the fastening ele ments ll extend. The U-shaped bracket l0 re ceives a nut I2 into which is threaded one end of an adjusting screw I3. This adjusting screw l3 extends through the 80 ear 9, through the bracket, and into the nut. The upper wall of the bracket holds the nut against rotation, and, consequently, by turning the screw l3 with a suitable instrument, such as a screw-driver, the strip 1 can be drawn toward 35 the bracket Hi. This will take up any sag in the door and hold the door in proper position against further sagging. In view of the fact that the anti-sagging device is formed from scrap metal, the same can be 40 secured to ?at wooden doors as well as screen doors and the like. 7 If desired and preferred, a removable sheet metal casing M can be provided for the bracket and the take-up screw I 3. Ears I 5 are formed on the casing I 4, which permits the casing to be secured to the door by screws I6. From the foregoing description it can be seen that I have provided an exceptionally simple and durable appliance, which can be quickly and eas ily applied to a door by a layman, and which will prevent the sagging of a door. Changes in details may be made without de parting from the spirit or the scope of my inven tion, but what I claim as new is: 55 2 , 2,133,719 legs, a nut received in said U-shaped bracket As a new article of manufacture, an anti-sag between the legs thereof, and adjusting screw ro appliance for doors comprising, an elongated ?at tatably mounted in the aperture of the ear ex strip of metal having its inner end folded back upon itself, said folded portion having a laterally extending apertured ear, the lower end of the strap being adapted to be secured to the lower outer corner of a door, a U-shaped bracket adapted to be secured to the door adjacent to its inner edge, said bracket having spaced apertured tending through the apertures of the legs of the U-shaped bracket and ?tted in said nut, and a detachable housing for ?tting over the bracket, ear, and screw.
