Improvements in Screen-Doors, Windows, My novel door includes five major ole-- orthe like, of which the followingis a'speciments, viz; a frame 1, an auxiliary fication. I frame 2 permanently fixed to the main The "obj ect of my present invention is the frame, a section 8 of screen or reticulated provision of a simple and extremely strong material, a screen frame 4 and at facing 5. 60 and durable screen door, window or the like, The main frame 1 is preferably, though not and one which the section of screen or renecessarily, made of wood, and comprises ticulated material is maintained under ztenan end bar 6, and side bars 7 The auxiliary .sion and in flat state, and which is so conframe 2 is preferably formed of sheet metal structed that the screen section may be exand is arranged against and permanently 65 peditiously and easily removed when. worn connected to one side ofcthe main frame. or broken and replaced by a 'new screen The said auxiliary frame 2 is provided with section without the employmentof skilled large openings 8 which are surrounded by labor "and without the loss of any part other flanges 9, Figures 2 and 4.. Said auxiliary than the worn or broken screen sect-ion. frame is also provided with a keeper flange '70 To the attainment of the foregoing, the 10 at oneend thereof within which is a rest invention consists in the improvement as 11, carried by the end "wall 12 of the auxhereinafter described and definitely claimed. iliary frame. It will also be observed by In the accompanying drawings, forming comparisonof Figures 1, 2 and 4: that the part hereof auxiliary frame 2 isprovided at points be Figure 1 is a front elevation showing a tween the outer corners of the flanges 9 and screen door constructed in accordance with the'cornersof the main frame 1 with commy invention and with a part. broken away." ifiar'atively shallow diagonal rests 13; At Figure 2 is a vertical central section of points between the inner transverse flanges 9 the longitudinal flanges-9 are recessed as Figure 3 is an enlarged detail transverse indicated by leandbestshown in Figure 2. section taken in the plane indicated by the It will further be noted that bolts 15 are line 3-3 of Figure 1. i carried by the auxiliary frame 2 and are Figure 4: is a detail interior elevation arranged about the flanges 9 thereof, F ig- 35. showing one corner of the main frame and ure 2, and that other bolts 16 are carried by the auxiliary frame fixed thereto; I I themain frame 1.

Figure 6 is an enlargeddetail transverse The sheet metal facing 5 is apertured to section showing how the screen section is receivethe bolts 15 and 16, and'from the connected to the side bars'of the screen foregoing it will be apparent that all that is frame. p necessary in order to associate the screen F igure 7 is an enlarged transverse section frame 1 and the facing 5 with the main taken in the plane indicated. bytheline 7-7 frame 1 and the auxiliary frame 2 is to of Figure 5 and showing a part of the means arrange the screen framed against the edges 5 to put the screen 'section under tension. of the flanges 9 and so that the extended end portions of the side bars 20 of the screen frame rest on the rests 13, and then slip one end of the facing 5 under the flange of the auxiliary frame 2 and so that said end rests between the flange .10 and on the rest 1 1. The screen frame at is not apertured. With this done, 'it being remembered that the facing 5 receives the bolts and 16, the nuts 18 are applied to retain the facing 5 and the screen frame 4- in position in the assembled door. From this it follows that-by merely removing the nuts 18 and disassociating the facing 5 and the screen frame 4 from the main frame 1 and the auxiliary frame 2, the

screen frame is rendered free to 'be'handled and 7 the screen frame a will be understood as comprising the side bars 20. preferably of. sheet metal, and cross bars 21. The said cross bars 21 which are also preferably of sheet metal, are fixed to one side bar 20 as indicated by 22. and are arranged loosely in apertures 23 in the otherside bar 20. The

screen or screen section 3 is connected to the sidebars 20 in the manner best shown in Figures 1 and 6-i.- e.. tongues 24: are struck up from the side bars 20, and the Screen section 3 hooked over the said tongues 24:. The tongues 2a are directed outwardly, and from this it follows that when the side bars 20 are thrust away from each other the screen section 3 will be placed under con-' siderable tension 'and will be rendered taut and flat throughout. To accomplish the said thrust in opposite directions of the side here 20 I provide the toggle lever equipment best shown in Figure 5, cachofthe toggle levers including a link 30 pivoted at 31 to one cross bar 21, and a link 32 pivoted at33 tothe link 30 and at 34 to one side bar 20.

Each of the links 30 is notched at 35, and

each link 32 is provided at its inner end with a reduced extension 37 which terminates in an angularly disposed stop portion BS-adapted when the toggle levers are pressed downwardlybeyond their centers to seat in the said notches 35. Manifestly when is this is done the toggle levers will be locked to maintain the screen section 3 in a stretched or taut state, and there will be no liability of the toggle levers being accidentally unlocked or permitted to flezrupwardly. 'When, however, 1t is. desired to render the screen section 3 loose so that the same may be unhooked from the tongues 24', the toggle levers may be expeditiously and easily flexed upwardly.

It will also be apparent from the foregoing that when the screen-frame 1 is in the state shown by full lines in Figure 5; the

said screen frame with its screen section 3 is of Figure :ble with the purpose of thesaid element.

adapted to be associated with the main frame 1 auxiliary frame 2 and facing 5 in the manner before described.

In the modification shown in Figure 8 the cross bars 21 are altogether omitted from the screen frame 4, and each of thetoggle levers of the screenframe is made up of links 30 and 32, the link 30 being pvioted at 31 to one side bar 20 and the link 32 being pivoted at 34* to the other side bar 20. The links'30 and 32 are pivoted together and are otherwise similar to the links 30 and 32 Consequently when the said links 30* and 32" are moved downwardly beyond center they will thrust the side bars 20 in opposite directions and will remain in the positions in which they are placed without liabilty of casual movement.

I would here have it understood that I prefer the construction shown in Figure 5, though I do not desire to be understood as limiting myself to the same.

It will be apparent from the foregoing that my novel screen'door-is adapted to last as a whole for an indefinite period of time, it being simply necessaryiat intervals of time to replace a wornor broken screen section 3 with a fresh screen section, and this as before pointed out may be quickly and easily accomplished without invoking the assist- 'ance of skilled labor.

The term door as herein employed is in tended to comprehend adoor, window or any other device that embodies a screen for the exclusion of flies and other insects.

I would further have it understood thatit is entirely within the purview of my invention to form any one of the elements of the screen door of any material that iscompati- Having described my invention, what I claim and desire to secure by Letters Patent, is i i 1. The combination in a screen door, of a mainframe, an auxiliary frame fixed to the main frame and provided withan end flange and with a rest spaced from. the inner side of and arrangedopposite said flange and also provided with large flanged openings and comparatively shallow rest portions, headed bolts carried by the main frame and the auxiliary frame, a screen frame arranged against said shallow rest portions, a screen carried by the screen frame and resting against the edges of the flanges defining said openings of the auxiliary frame, a facing arranged over the screen and screen frame andreceiving the bolts of the main frame and having one end interposed between the said end flange and rest spaced therefrom,

. boltsextending through the auxiliary frame 2. The combination of a screen frame having portions one of which is movah1e laterally toward and from the other, a screen connected to and extending between said portions, and means to thrust the movable portion away from the other portion and to lock it against inward movement to render the screen taut and maintain it in tight and flat state; the connection of the screen to said portions being efiected by outwardly directed tongues on the portions extending through interstices of the screen, whereby when movement of the portions toward each other is permitted the screen may be readily detached from the portions.

In testimony whereof I afiix my signature.

EMIVIETT E. MILLER.
