Application filed June 12, 1908. Serial No. 488,160.

To all whom it may concern.

Be it known that we, HARRY F. BITTLIN- GER and JOHN J. ENNIS, citizens of the United States, residing at Covington, in the county of Kenton and State of Kentucky,

have jointly invented certain new and useful Improvements in Wire Screens, of which the followin .is a specification.

Our invention re ates'to wire screens and is especially applicable to screen doors, although the same may also be applied to Window screens. We have, however, illustrated the invention as applied to a screen door. a

The invention will be readily understood from the following description and claims, and from the drawings, in which latter:

Figure 1 is a rear elevation of our improved device with the screen-cloth partly broken .away for better illustration of parts. Fig. -2 is a front elevation of the same. Fig. 3 is an enlarged view in rear elevation of the corners of the main frame-sectlons of our improved device, the intermediate portions on the line yy of Fig. 4 showing the manner of connecting the securing means to the frame-section; and, Fig. 9 is' a cross-section on the line zz' of Fig. 2- showing the manner of securing the screen-cloth in place.

The main frame of the screen comprises frame-sections 1 2 which embrace stiles a,

top rail 4, and a bottom rail 5. These framesections are composed of angle iron'or other metal comprising the inwardly extending flanges 6 and the rearwardly extending flanges 7. Each frame-section preferably has an integral corner 8 at which the inwardly extending flanges are cut away, as

shown at 9. This ermits the rearwardly extending flanges to ae bent for forming the corner. he adjacent diagonal end-faces 10 of the inwardly extending flanges are preferably spaced apart slightly for permitting this corner to be sprung as hereinafter described. One of the outer ends of each frame-section is preferably provided with a recess 11 and the other outer end of each frame-section is provided with recesses 12 13, there being a tongue 14 at the recesses 12 13 for being received by the recess 11.

The frame-sections are shiftable with relation to each other for permitting the len 11 or width of the screen to be varied wit in limits forfitting the-opening to be filled by the screen, and the manner of forming the integral corners 8 also permits the framesections to be bent or s rung at said corners for permitting the re ative angle between the stiles and rails of the frame-sections to be changed for fitting the opening into which the screen is to be received. We providesuitable bracin and securing means connecting with the ame-sections for holding the same rigidly in adjusted positions and for hiding any gaps there may be either in the frame-sections themselves or between said sections, which we will now describe.

17 are inner corner-pieces adapted toform connections between the respective outer ends of the fran'ie-sections. They are shown as angle pieces having inwardly extending flanges 18 and rearwardly extending flanges 19 and are provided with slots 22 through which screws 23 pass into threaded apertures in the res ective frame-sections for securely holding tl ese frame-sections to ether in adjusted positions. The inward 'y extending flanges 18 are arranged to' span and hide the spaces, if any, between the outer adj acent ends of said frame-sections.

26 are holding strips for the screen-cloth 27. These strips extend longitudinally of the stilesandrails of the frame-sections and are preferably slightly channeled lengthwise as-shown at 28 forformin an inner contacting edge 29 on each str 1p'- between which and the frame-section the screen-cloth is adapted to be clamped,-as by means of screws 30 passing, through apertures in the strips and ,intothreaded apertures in the frame-sections.

In order to hide and strengthen the joints at the corners of the screen at the front we provide outer corner-pieces 31 having slots 32 through which some of the screws 30 may pass for holding the outer corner-pleces in place. For bracing the corners and stifiening theframe We provide diagonal bars 35 secured to plates 36 fastened to the rear faces of the frame-sections, screws 37 passing through slots 38 in said plates and into nal bars for securing the'bars"=to said plates,

the plates being distanced rointhe inwardly.

extending flang def-{the frame-sections 'arl'd the plates 36 beby spacing-block ing secured 1 0 d inwardly extend ng flanges by of rscre'ws 4Q passing through said plates-36 and spacing-blocks eraan threaded apertures jtending flanges 6.

4142 arebrac'ef-rods pivotally secured to the frame-sections at one end as shown by the screws 43 44 which pass through said brace-rods and into internally threaded apertures in saidinwardly extending flanges 6. At their other ends these brace-rods are adj stably secured to the opposing framesections by means of adjustable securing clips 45 provided with slots 47 48 arranged at right angles to each other, the slot 48 be- -ing in an extension 49 of the clip. A screw 50 passes .through slot 47 into an internally threaded aperture in the inwardly extending flange 6, and a screw 51 passes through slot 48 into an internally threaded aperture in the end of the brace-r0d.' If the opening which the screen is intended to fit is out of square, the main frame of the screen may be adjustedto suit the opening and the securing" clips shifted upon the frame-sections by'meanslof the slot and screw connection therewitlr. The brace-rod may also be ad justedtQf-Izosition, and, in connection with the extension49, the effective length of the cross-bracelg may be adjusted. The screendoor maybe-hung on hinges 52.

In fitti g 'our'improvcd screen to an opening thesefcuring means between the framesections,wh ich, as shown and described, are preferably" Leshaped in cross-section, are

, loosened so as to be able to shift the framesections to fit the opening, when said securing means are fastened. The screen-cloth is then mserted under the holding-strips'26,

which latter are then screwed down upon the frame-sections, the screen-cloth being meanwhile stretched, the inner contact-edges 29 of thevholding strips making intimate contact with the screen-cloth for clamping the same in position. We refer that these holding strips shall be 0 metal and our improved deviceforms a'screen which is very substantial and extremely simple. also very duranle' and the screen-cloth is easily removed,- repaired or replaced, and the screen is .chea in construction. horizontally exten ingbrace-rod is preferably placed at such height as to receive the pressureof the hand.' The outer cornerpieces span the joints, shown in dotted lines in Fig. 2, between the holding strips at the corners of the screen.

Having thus fully described our invention what we claim as new and desire to secure by Letters Patent is:

It is The ' 1. A metallic screen comprising a pair of main frame-sections of L-form in cross-section, each of said frame-sections having an inwardlypxtending flange and a rearwardly extending flange, each of'said frame-sections 7 having its inwardly extending flange cut inner corner-pieces spanning said ends, and

adjustable means for securing said cornerpleces to the-respective ends of sald framepieces for forming extensible corners, substantially as described.

2. A metallic screen comprising a pair of main frame-sections of L-form in cross-section, each of said frame-sections having an inwardly extending flange and a rearwardly extending flange, each of said frame-sections having its inwardly extending flange cut away at a point intermediate of its length and its rearwardly extending flange bent at said point for forming a corner in tegral therewith, the outer ends of said frame-sections being provided with mating ends, inner corner-pieces s anning said ends, and adjustable means or securing said corner-pieces to the respective ends of said frame-pieces for forming extensible'corners, said inner corner-pieces having inwardly extending flanges spanning and hiding the 4 joints between said frame-sections at said extensible corners, substantially as described. 1
