PATENT OFFICE 1,987,080 wmnow scar-21m Henry J. Schneider, New York, N. Y. Application July 2'7, 193:, Serial No. 682,363 10 claims.- (01. 156-14) different sizes in order to fit thevarious different sizes of windows. with this invention a dealer or manufacturer will only have to stock a comparatively small number of sizes in order to meet demands made upon him for a great stood as this description proceeds, that the said many different sizes of window at the present time used.

It is an important object of this invention to screens which are provide a window screen to fit any of the various sizes of window frames by simply adding the proper lengths of wire fabric to the frame of the window screen constituting my invention.

Another object resides in the provision of simple, reliable and easily operable means for tensioning the screen fabric and which will permit of the screen being swung outwardly to an open the invention, reference may be had to the fol-.

lowing description and accompanying drawings wherein: f

and

In the drawings, which are fllustrative of one practical embodiment of the invention, in Fig. 1

thereof I have shown my new screen as extending for substantially one-half of the vertical length of the window frame. It will, however, be underinvention is applicable as well to a full length screen extending over the entire area .of the window frame opening.

Referring in greater detail to the accompanying drawings, the wire mesh fabric indicated at 14 is cut from a roll to approximately the required length. The upper and lower edges of the screen fabric are securely held in clamping devices extending across the entire width of the fabric. Since these clamping devices are of the same construction, the following description of one clamping device will suflice for both.

As seenfi'om reference to Figs. 2 to 9 of the drawings, the screen clamping device consists of two metal bars, 1 and 3 respectively, of shallow channel shaped form. These bars are arranged in opposed relation,

tions, and on opposite sides of the screen fabric with their longitudinal .fianges projecting in relatively opposite direc- 5 14 which is interposed between said bars as'indicated at 2 in Fig. 2 of the drawings. Each of the clamping bars '1 and 3 has a plurality of prongs or teeth 9, struck therefrom; which are adapted to engage in the mesh of the screen fabric 14, and hold the same against shiftingrelative to said bars while the clamping bolts indicated at 4 are applied. The outer clamping bar 1, has circular openings therein to receive said bolts each of which is providedv with a reduced rectangular shank section indicated at 4', to be resash guide ribs on the window frame as shown in' Figs. 2 and 6 of the drawings.

Upon the sash guide ribs at suitable points in accordance with the length of the screen the.

bracket members are secured. Each of these members in the central portion thereof has a vertically extending slot '1', opening laterally at its upp r end toward the outer side of the window frame. A complementary bracket member 8 is' suitably fixed to each end of the bar 3 of the upper clamping device and carries a stud indicated at 8' adapted to be inserted into the upper open end of slot '1' in one of the members '1, and removably seated in the lower end of said slot.

In order to compensate for 'any inaccurate cutting of the screen fabric 14, particularly when it is intended to screen the entire area of the frame opening, I provide the additional relatively short sections of screen fabric indicated at 10 having suitable metallic bindingstrips 11, applied to one longitudinal edge thereof, while the other edges of said screen sections are securely held between bars 1 and 3 of the respective clamping devices so that the said screen sections 10 will thus project above and below the respective clamps.

- To the lower end of each sash guide rib on the window frame a vertically extending channel shape plate 12 is secured and between the parallel flanges 12a of this plate, the vertically disposed toothed strip12b is positioned. This-toothed strip forms part of a ratchet device-for vertically adjusting or stretching the screen fabric 14,

and may be conveniently formed as an integral part of the channel plate. It is preferably longitudinally bowed or curved as indicated in Fig. 7 of the drawings. 7

The other part of each ratchet device consists of a manually operablemember 13a. This member comprises a disk eccentricallypivoted as at 13b in a bracket member or plate 13c suitably fixed to the inner bar 3 of the lower screen clamp. This bracket plate is formed with an offset flange 13d which has a free sliding fit between one of the flanges 12a and the ratchet strip 12b of the channel plate secured to the sash guide rib. The adjusting members are provided with peripheral teeth to coact with the teeth of the respective ratchet strips 12b. Thus it will be understood that by the operation of the members 130 in a clockwise direction, the lower screen fabric clamp will be forced downwardly and thus tightly stretch the screen fabric to a taut condition. The ratchet strips 12b are yieldable or resilient, and due to the eccentric mounting of the members 13a will be placed under tension, so that they will exert sufiicient frictional pressure against the members 13a to resist any tendency of said members to casual movement from their adjusted: positions, whereby the tightening strain on the screen fabric would be released.

From the above description the manner of operation and the several advantages of my invention will be clearly understood. The brackets '7 are so located or positioned with respect to the outer edge faces of the sash guide strips that when the studs -8' are seated in the slots 7' of said brackets, and .the flanges 13d are engaged with the flanges 12a, the opposite vertical edges of the screen fabric will be held in very close relation to said guide strips. The upper screen section 10 may be slightly bent with respect to the-screen clamptoclosethespacebetweensaidclampand thelower-mdoftheupperwindowsash. Thus the window frame opening will be effectively screened. Whenthescreenismadetoextendthe tact with the top and bottom of the window frame.

'lhusitwillbeunderstoodthatthepartsofmy new improved window screen may readily be adiustedso as to provide an accurate fit for window frames of various lengths.

-In the event the screen fabric should become broken, it may be readily removed. from the clamping devices and new fabric substituted therefor.. Also by lifting the lower end of the screen to position the flanges 13d above the flanges 124:, the screen may be swung outwardly to an open position without disengaging the studs 8' from the slots '1'. In the winter the wire fabric may bereplaced by cloth fabric and the device used as a ventilator.

When not in use the screen fabric may be tightlyrolled and together with the clamping devices stored away in a small space. 4

I have herein disclosed a simple and practical embodiment of my improvements, which enables the various adjustments to be made with ease and facility and also permits the screen to bereadily largely suggestive. and his therefore to be understood that I reserve the privilege of incorporatspecific structural features of the-invention is ing the essential features of the invention in various other mechanical forms with resort to such modifications of the illustrative example as may be fairly considered within the spirit and scope of the invention as claimed.
