AUTOMATIC WINDOW SCREEN Filed Oct. 28, 1956 INVENTOR. Y f llfil chafacz v ATTORNEY Patented Oct, 19, 1937 PATENT OFFICE AUTOMATIC SCREEN Walter Zychewicz, Chicago, Ill., assignor of onehalf to John Brandys, Chicago, Ill.

Application October 28,

2 Claims. The-present invention relates to window screens and has for its main'object the provision of a screen adapted to siinultaneouslyandautomati cally operate with the raising or lowering-of a window sash with which the Window screen'is 7 adapted to co-operate. Y

A still further object'of the present invention is the provision of a window screen of the type indicated operablein conjunction with a spring wound roller to which one end of the screen may be attached and which roller maybe mounted upon suitable brackets affixed to the window sash,

and wherein the other end of the screen may be afiixed to the frame, 7

Astill further object of the present invention is the provision of aneficient means for attaching the screen to the window whereby the same may be easily aflixed to or removed from the window.

" Astill further object of the present invention is the provision of a suitable bracket in connection with a window screen of the type indicated which'will facilitate'prompt and easy attachment of the screen to the Window and a removal of the screen therefrom.

With the above general objects in view and others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in 30 the accompanying drawing and pointed out in the appended claims.

In the drawing forming a part of this appll cation, and in which like designating characters refer to corresponding parts throughout the several views;

Fig, 1 is a cross-sectional view longitudinally of the window showing the position of the screen when the window sash is closed;

Fig. 2 is' a similar View indicating the positio of the screen when the window sash is in a raised condition;

Fig. 3 is a fragmentary elevational plan view of the window with the lower sash raised, showing the operation of the screen;

Fig. 4 is a cross-sectional view through the roller and screen, the view having been taken on line 44 of Fig. 5;

Fig. 5 is a fragmentary cross-sectional view through the window sash, Window frame and the roller;

Fig. 6 is a horizontal cross-sectional view through the window with the top plan view from above of the brackets, roller and the screen;

Fig. '7 is an elevational face View of one of the brackets; and 7 1936, Serial No.-107 ,93(i

Fig. '8 is the end elevational View of the roller with the screen wound around it.

Referring to the drawing there is shown therein-a window including frame iii and sill ll. Positioned Within the frame for vertical sliding movement is an upper window sash l2 and lower window sash l3, which latter includes a lower horizontal sash bar l4.

The present invention includes a spring wound roller l5 made of metal or any other suitable rigid material. Longitudinally of said roller l5 runs an inwardly depressed groove l6 for reoeiving therewithin one end of screen I! which is held in position within said groove It by means of rod l8 frictionally insertable Within said groove l6 for the purpose of clinching therewithin said end of screen l1.

Positioned within said roller i5 and concentrically with its axis is rod l8 which passes centrally of caps l9 positioned adjacent each end of saidroller l5 and wherein they are frictionally held. For strengthening the ends of said roller [5 collar 20 is passed over each end of roller I5 with which it frictionally contacts. Said collars 20 also hold rod It! in position. Each of said collars 20 has an integrally formed flange 2| angularly disposed relative to the collar 20, which prevents the outward creeping or sliding movement of caps l9 and of rod iii.

A coil spring 22 set within roller l5 and around rod I8 is rigidly attached by one of its ends to said rod l8 as at 23, while the other end of said spring 22 is rigidly afiixed, to roller l5 as at 24.

One end of rod l8 extends beyond roller I5 as at 25 which is adapted for engagement by bracket generally indicated on Fig. 6 by numeral 26, while the opposite end of said rod [8 likewise extends beyond the adjacent end of roller I5 and has an integrally formed arm 21 which fits within bracket, generally indicated on Fig. 6 by numeral 28.

Each of said brackets 26 and 28 includes an annular flange 29 from which raised and struck out body portion 30, of cup-like appearance, outwardly projects. Bracket 26 has an aperture 3| made centrally in its body portion 30, while bracket 28 has a radial slot 32 made in its raised body portion, as clearly seen on Fig. '7, for receiving therewithin arm 21 of rod I 8.

Each of said brackets 26 and 28 is further provided with a leaf 33, integrally formed therewith and angularly projecting therefrom through which screws 34 may be passed for the purpose of mounting the brackets upon the lower horizontal sash bar 14 of the lower window sash.

Part of the raised body portion of bracket 28,

- ation. When the lowerwindow sash is raised the;

which immediately projects from flange 29 ata point in alignment with slot 32 is slit as at 35 for the purpose of providing an unimpeded communication with said slot 32 for inserting or removmounted upon the lower horizontal sash bar 1,,

flanges 29 thereof remain in the proximity of the adjacent facesof the window frame l0, while the raised central body portions 30, thereof are disposed inwardly of the window.

Prior to mounting roller IS with its screen I! upon the window sash within brackets 26 and 28, screen IT is first wound around said roller l5,

thereupon by means of arm 21, which constitutes a lever for that purpose, rod I8 is rotated for winding up spring 22. w

While manually maintaining said arm 21 against revolving due to the tension of spring 22, end 25 of rod I8 is inserted within'aperture 3| of bracket 26, and thereupon said arm 27! is inserted withinradial slot 32 forcing'the sameto slide within said slot as far as it will go. Thereupon bar 36 is suspended upon pins 3'|.- When the device remains in the described operative position in'the window the screen is ready for operroller I5 is caused to revolve around rod l8 which remains in a fixed position within brackets 26 and 28, which causes the unwinding of screen I! for spreading the same within the open space cleared by the window sash. When the lower Window sash is being lowered; spring 22, due to its torsion,

causes the rotation of roller H) in the opposite direction which operation causes the winding of 7 screen ll around said roller 15, so that when the window sash is entirely closed screen I1 is almost;

2,096,443 r J l I entirely wound upon said roller 15, which twov operations and respective positions of said screen "are illustrated on Figs. 1 and 2. Due to -torsion of spring 22rol1er l5 remains at all times under'tension by virtue of which fact screen I! remains almost completely wound around roller l5 when the window sash remains in ,-a closed position within the window frame, and remains in an even stretched conditionwhen the window sash is in an open position;

Screen H may be made of wire orfabrici If V the latter is used, stifi, glued organdie is prefer- While there isdescribed hereina preferred embodiment of the present invention, it is nevertheless to be understood that minor changes maybe made therein Without departing from the spirit and scope of the-invention as claimed.

What I claim as new is:

1. In combination, a screen roller, arod in an said rod, and by the other end to said roller, both ends of said rod extendingbeyond the adjacent ends of said roller, an arm rigidly'forrned with 1 one end of said rod and laterally projecting there- 7 from and in transverse relation with said roller,

and abracket having a raised body portion provided with a radialslot receiving therewithin said arm for maintaining said rod, in rigid position.

2. In combination, a screen roller, a rod in axial and longitudinal relation withsaid'roller, tensioning means within said roller, an arm laterally projecting from one end of 'saidfrod andipin aradialtransverse relation with respect to said roller; anda bracket having a raised body portion provided with a radial slot, said armconsti- 7 tuting means for ,rotatingsaidrod for operating said tensioning means, said arm being received within said slot.
