ADJUSTABLE SCREEN.

Application led July 18, 1923, Serial No. 651,695.

1To all whom t muy concern:

Be it known that I, CASPER HUGO GRINGS, a` citizen of the United States of America, and a resident of .llVaterloo, Blackhawk County, Iowa, have invented certainv new and useful Improvements in Adjustable Screens, of which the following isa speciiication.

`My invention relates to improvements in adjustable screens, and the object of my improvement` is to supply for wall apertures including windows havingmovalole sashes, a flexible screen element, which may or may not beof reticulated material, and cooperating holding and supporting elements for keeping the screen in a proper .position covering such an aperture, the screen coacting with the said elements insuch a` manner as to be adjustable therein in the direction of its length.

I `have accomplished this object by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from t-he spirit of the invention.

In saiddrawings, Fig. l is an elevation of the inner face of a sashed window, showing the lower sash partially elevated and my imw proved adjustable screen mounted within the casing to close the opening beneath said sash. Fig. 2` is an elevation of the screen member only as unrolled before adjustable mounting thereof in a window casing. Fig. 3 is a-top edge view of the screen member showing its tubular stile receiving ends placed in appropriate positions relative to the main body of the screen for conveniently mounting these tubular ends in grooved holding devices mounted on the opposite jambs of saidv casing. Fig. 4. is a horizontal section on` a larger scale of a window casing and ofthe lower sash ther in, showing my improved screen mounted across the casing, parts being broken away.

Fig. 5 YVand Fig. 6 are respectively enlarged perspective views of theupper and lower clips of the device. Figs.'7 -and- 8 are perspective views of the upper ends of the .screenholders showing the rolled endsof the iiexible screen member mounted in the grooves thereof. Fig. 9 is an enlarged perspective view of the fastener used to secure the upper longitudinal edge of the screen member under and to a finger-lift on the lower sash. Fig. l() is a top plan view of the said fastener in use securing said screen to said finger-lift- Fig. ll is a horizontal section of an end stile and of the holding element therefor.

It is well known that even in the same building or other structure window openings often vary in width, so that it is desirable that a screen member to properly cross and lit any of the openings should be adjustably adaptable theretoand then supported under propertension in such a manner that it will closely contact with the adjacent structures to prevent ingress or egress of air otherwise than under the conditions. for which the screen is designed.

lith this end in View, I supply aflexible screen sheet l, which may be impervious to air if desired, or may be made of reticulated material to permit a gentle transpiration through its substance.` The horizontal longitudinal margins l5 and 16 are turned over tubularly and hemmed, as are also ,the opposite end margins at 18 and 19. As shown in Fig. 2, a short vertical slit may be made in the lower tubular part 16 at 38 to permit either the introduction or the removal of a metal rod 17 which thus serves as an` elongated weight to keep the lower margin of the screen l straight as also drawn down to contact closely with the sill member 32 underneath.

llhen the rod 33 has been removed the" screen may, together Vwith `Hat sticks or stiles 14; in the end tubes 1S and 19, be rolled up to occupy but little space.

I supply the following described holding devices for the ends of said screen; leftshand device shown in Figs. l and 7 `is an elongated vertically disposed plate 0f metal 2 having one vertical margin bent to one side at a right angle at 4, the outer edge of which is notched at 5 for the adjust-4 able placing of screws 6 `to secure the holder to the jamb 31 with the body 2 closely abutting' the inner face of the lower sash 28 cross-bar when the sash is raised. This holder Q. has its right-hand margin curvilin- The early bent over to the same side to form a groove or channel at 3. The body 2 has holes as at 7 to receive pivot-screws 34 on which spring-clips 8 and 8 having registering holes 13 are pivotally mounted.

The right-hand holder 2O has its inner margin ciirvilin early grooved or troughed at 23 toward the window to abut closely upon the sash, the holder being bent slopingly at 21 toward the outwardly directed marginal part 22 to thus mount the holder in position.

The ends of the screen 1, as shown in Fig. 3 maybe bent around in opposite' directions loopwise with their st-iles 14 so as to permit the tubes 18 and 19 with said stiles to be respectively slipped endwise doiiiiwardly into the holder grooves or inturned margins 3 and 23 after the screen in case of need has had its ends rolled one or more times around the stiles to effect the proper longitudinal tension in the screen. This disposition ot' the rolled extremities of the screen is best illustrated in said Figs. 7 and S. Vhen the screenhas been thus flatly stretched and end-seciired in said holders, additional tension vmay be made therein to take up any residual slack by means of the said springclips 8 and 8 These clips are alike, except that'the upper clip 8 has its :tree terminal bent away from the screen at 9. Each clip l is bent toward the holder 2 in an offset at 10. and 11, to override the bent margin 3 with sufficient clearance, when swiingdownwardly to engage the tree extremity with the' screen adjacent the holder as shown in Fig. 4t. This bends the screen against the sash closely, while at the opposite end of the sash the screen is held in contact with the latter by the holder bent margin Q3. Each pivoted terminal l1 of the clips has a curved cam edge 12, which clears the abutting part 4 of' thel holder when the clip is Vswung iipwaidly to disengage it 'from the screen 1, but to engage the part L when swung downwardly to hold the clip longi-v tudinally directed relative to the screen.

Vhen one or more lifting handles 24; are

'provided on the lower cross-bar oi the sash trame 28. the upper longitudinal 'marginot the screen may be kept in close contact with this cross-barby the following device. The i device is a small .met-al plate 25 whose iniddle part is curved semicirciilarly at 27 and its end parts partially separated by slots to provide the springlingers 26. The device' is mounted with its middle raised part 2T under and enga-ging the lifter hook 24, the upper margin of the screen being inserted in said slots back. ot the lingers 26 which latter thus hold the screen tightly in place against' the sash cross-bar.

This type ot screen is thus readily adjusta-ble in its length to window openings of varying widths, so only one size ot screen need 'be carried ,in stock.

sash mounted movably in said casing.`

inserted in a grooved holder 3 or 23 the flat 70 stiles cannot rot-ate while under tension, within the groove narrower than t-he stiles width.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:V

l. In combination, a flexible screen, flat stiles connected to the ends thereof, and grooved holding devices whose ,grooves are narrower thanrthe widths of said stiles adapted to be removably mounted on the.` jambsof a window-casing to releasably` receive and retain under longitudinal tension the stiles interlockingly and non-rotatably Q5 and said screen. L'

2. In combination, a Hexible screen having. tubular ends, stiles removably mounted'in said tubular ends, grooved platesremcvably mounted Von supporting-means to receive said tubular ends and stiles interlockingly and non-rotatably, and resilient( pressures fingers mounted pivotallypon one of said 'plates to engage and tension said screen ad jacent the plate.

3. In combination, a exible screen having tubular endsg'stiles removably mou-ntedin said tubular ends, the screen being windable" at its lends around said "incased stiles to shorten itsv length adjustingly, and means mounted removably -on opposite window jainbs to .i-eleasablyfand interlockingly i'e-` `cei've and hold said incased stiles non-rotatably with the screen` wound thereon under lengthwise tension.

4. In combination, a
