To all whom it may conceive:

Be it known that l, RICHARD E. Moore, 21

citizen of the United States, residing at- Agency, in the. county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Screen Doors, of which the following is a specification.

' This invention relates to screen doors and its object is to provide inexpensive means whereby sagging of the door or warping of a stile will be prevented, the invention seeking to provide means for the stated purpose which will be light, easily applied. and durable. The invention is illustrated in the accompanying drawing and "will be hereinafter fully set forth.

in the drawing:

Figure l is an elevation of a screen door having my improvements applied thereto;

Fig. 2 is an edge view of the door;

Fig. 3 is an enlarged longitudinal section or one of thestretchers and its mounting;

Fig. 4 is an enlarged elevation of one of the truss bearings and guides; v

Fig. 5 is a perspect ive of one of the guides, and

Fig. '6 is a perspective of an anchoring member.

The door 1 may and is mounted in be of any preferred form the usual manner. Along .the free stile 2 of the door, "I secure a plurality oi truss members 3 which, as shown mOSt clearly in Fig. 5, consist of similar metellic plates 4 shaped to produce a sleeve or eye 5 at the outer ends of supporting webs the webs being spread laterally, as shown at 7, whereby they may rest flat against the stile and be secured thereto by screws or similar fastening de vices. Obviously, the sleeve may be free of joints and constitute a connection between the outer end edges of the webs. I find it to be advantageous, however, in making and assembling the parts of the invention, to form a half sleeve on each web and secure them in mating relation by inserting a rivet 8 through the webs. The base plates or feet 7 are somewhat tapered and terminate in spurs 9 which may easily penetrate the stile to aid in maintaining the bearing in place, openings 10 bein provided in the feet to permit the insertion of the securing screws or nails. As shown most clearly in Fig. 2, the supporting webs 6 of the several truss bearing members are of difierent lengths, the central member having the greatest length or height and the other members being successively reduced in height so that a tension wire 11 inserted through and carried by the several sleeves or eyes 5 will be given an arched or trusslike form, as shown clearly in Fig. 2, to

counteract any tendency of the stile to warp.

One end of the tension wire 11 is connected to an anchoring member consisting 'of a plate 12 having one e e notched and rolled upon itself whereby to provide elined bearings 13, and a bail or clevis 14 having its terminals 1.5 spread laterally to be engaged in the said bearing sleeves 13, as shown clearly in Fig. 6. lhe end of the tension wire is wrapped around the shoulder or bridging member of the bail, between the sides thereof, and may be tiedthereto in any approved manner. The opposite end of the tension wire is connected with a stretcher ldwhich consists of e metallic-plate or strap bent midway its ends to provide parallel side portions 17 and a bridging member'lS connecting the said side portions. The free ends of the side members are perforated, as

shown at 19, to receive the hooked ends 20 of a clevis or bail 21, the upper end of the tension wire being wrapped around and tied to the shoulder or lower end of the clevi s. The bridge portion 18 of the stretcher is disposed egainst' the stile and is held thereto .by a

bracket consisting of a. bar or strip of sheet metal having its end portions bent vto define feet 22 to be attached to the stile, and

a bridge member 23 extending longitudh nally of the stile and held in spaced relation thereto by the webs 24 connecting thesaid bridge with the feet 22. The webs 24care provided with suitable openings in which is mounted on adjusting screw 25 having its ends swiveled in the webs and its intermediate portion passing through a corresponding opening 1n the bridge member 18 of the stretcher. A nut 26 is engaged with the screw between the lower end of the bracket and the bridge piece 18 of the stretcher and bears'against the said bridge, the out being prevented from turning by the engagement of its sides with the bridge member of the bracket and the sides of the stretcher. One end of the adjusting screw is suitably constructed to be engaged by a. turning tool, and it will be readily seen that rotation of the screw will cause the nut to ride longitudinally upon the Screw" and thereby shift the stretcher longitudinally place the wire8 under any desired member 28 corresponding in all respects to the anchor 12. At the upper corner of the door, a bracket 29 is secured to the hinge stile 30 thereof, and a stretcher 31 is en gaged under the said bracket, as, shown in Fig. 1. The bracket 29 corresponds in all respects to the bracket 22, 23, and the stretcher 31 corresponds in all respects to the stretcher 16. A' tension wire 32 is secured. to a1" ntends between the anchor 28 and the stretcher 31, and is put urn der proper tension by adjustment 0d the said stretcher so that it tends to resist and overcome any sagging tendency which may developin the door. Theihandle 27, as shown in Figs. 1 and 2,, is provide-d with terminal feet which rest against and are secured to the stile and the dividin bar .re-

spectively of the door, and one toot rests upon the-anchor 28, a single fastening screw or nail serving to secure bothelements in lace. P It will be readily seen that I have provided exceedingly inexpensive and eliicient means for preventing sagging or warping of a screen door and that the devices of the invention may be easily applied to the door by an unskilled person and, when applied,

will operate in a highly eiiicient manner.

The present construction minimizes the number of parts, thereby simplifying the manufacturing processes and reducing cost. The tension wires are preferably two strands twisted together and are soillustrated.

Having thus described the invention, 1 claim:

1. Means for the purpose set forth com prising an anchor member, a bracket spaced from the anchor member and comprising end attaching portions and an intermediate bridging portion, a stretcher comprising parallel side members embracing one end portion of the bracket and an end member connecting said side members and slidably engaged under the bridging portion of the bracket, a tension member engaged at (me end with the anchoring member and at its inner ends minals engaged in the bearings, a stretcher, v

means for adjusting the stretcher and socur ing it in a set position, and a tension mem ber secured at one end in said bail and at its opposite end to the stretcher.-

3, Means for the purpose set forth comprising an anchor plate provided at one end with alined bearings, a bail disposed between said bearings and having lateral terminals engaged in the bearings, a stretcher, means for adjusting the stretcher and secur .ing it in a set position, a tension member socured at one end in said bail and at its opposite end to the stretcher, and a plurality of alined sleeves disposed between the anchor and the stretcher and encircling and supporting the tension member, the sleeves being in stepped relation from the central sleeve to the end sleeves.

4. Means for the purpose set forth comprising an anchor plate provided at one end with alined bearings, a bail disposed between said bearings and having lateral terniinals engaged. in the bearings, a stretcher,

means for adjusting the stretcher and securing it in a set position, a tension member secured at one end in said .bai'l andat its opposite end to the stretcher,

and the stretcher and encircling and supporting the tension member, the sleeves be ing in stepped relation from the central sleeve to the end sleeves, supporting webs carrying said sleeves at their outer ends, and tapered feet extending laterally from tho of the Webs and terminating in spurs, i
