WINDOW- SCREEN.

SPECIFICATION forming part of Letters retent Ne. 5o7,s44, 1etea oetober 31, 1893.

Application le'd April 21,1893.

.To all whom t may concern,.-

Be it known that l', JEROME RICH, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Window-Screens, of which the following is a specification, reference bein-g had therein to the accompanying drawings.

The invention consists in the peculiar construction, arrangement and combination of the various parts as more fully hereinafter described.

In the drawings, Figure lis an elevation of a window frame showing my screen in position partly in section. Fig. 2 is a cross section on line az, Fig. l. Fig. 3 is an enlarged perspective view of the lower edge of the screen. Fig. 4. is a cross section on line y y in Fig. l. Figs. 5 and 6 are views illustrating the manner of constructing the screen.

My screen belongs to that class in which the wire cloth is secured to a roller at'the top of the window frame and adapted to be wound thereon or unwound therefrom in raising or lowering the screen. In the use of such screens heretofore it has been found necessary to use a spring roller to raise the screen, and it has also been found necessary to prevent the bagging or sagging of the screen to provide means at the edges for preventing the withdrawal laterally from the guides of such edges. My invention enables me to dispense with the spring roller and also to dispense with the securing devices for the edge of the screen. I have found that by winding the screen on the rollerunder sufficient tension or pressure to give the wire a permanent spiral set it will practically act as its own spring for raising the screen and winding it about the roller and by making a rigid frame for the lower edge of the screen it enables me to dispense with the securing devices for the edges.

A is the window frame. B are brackets at the upper end thereof secured at each side. C is a roller journaled in said brackets.

I) is a hood of substantially circular shape, as shown in Fig. 2 and 'having the flange or plate E extending across the window frame in rear of the roller.

F are standards or strips secured to the inner face of the window frame and having groovesGon their inner edges. These strips Serial No. 471,265. (No model.)

are bifurcated at their upper ends to receive the lower end of the bracket. The screw H passes laterally through the bifurcation and into the bracket as shown in Fig. l, thus enabling me to secure the bracket in position upon the frame with a minimum of screws in the wood-work.

I is the screen. In securing this screen upon the roller I first secure the upper edge of the screen to the roller and then secure the roller in a suitable rotary socket having a crank handle J, as shown in Fig. 5. Upon the screen I 'then place a weight K, or apply spring pressure, or in any other way holding it under pressure, While I wind the screen about the roller, so that it will be wound about the roller with sucient tension to impart a permanent spiral set to the screen. To aid in this I in- Sert the screen when wound about the roller into a clamp or socket L, as shown in Fig. 6 and allow it to remain a sucient time to become permanently set in its spiral form.

The lower edge of the wire I secure in a rigid metallic frame, constructed preferably as shown in Figs. 3 and 4 and consisting of the cross-bar L and the guide strips M at the ends of the cross-bar. This I preferably make of tin or other suitable sheet metal, folding the tin double to form sockets in the top of the cross-bar and the inner side of the guide strips into which the lower edge and the lower end of the side edges of the wire cloth are adapted to be engaged.

To secure the cloth in the cross-bar I preferably double it upon itself, as shown in Fig. 4., by making the loop or bend N. The frame thus constructed engages in the slots or grooves Gof the strips F and forms the means of guiding the wire cloth in its vertical movement. I preferably secure the cross-bar L in a wooden cross-bar O, securing it in a slot P therein, by means of suitable screws, such as Q. I have found that this structure makes a rigid frame for the bottom of the screen; that no means are required for guiding the screen at the edges to prevent its sagging or bagging and that by forming the screen with a permanent spiral set about the roller a plain roller may be used without any spring, and the screen will naturally coil itself about the roller as it is raised.

By using the strips F on the outside of the IOO Window frame it is evident that my screen may be attached to any Window Without changing the frame, except by the addition of these strips, which may be readily removed when desired and which do not detract at all from the appearance of the frame. In fact the structure is ornamental and may be left in place Winter and summer.

What I claim as my invention is- 1. In a window screen, the combination of the roller, the wire cloth secured at one end thereto and wound spirally about the roller with a permanent spiral set, substantially as described.

2. In a Window screen, the combination of the roller, brackets in which the ends of the roller are journaled, the wire cloth secured at one end thereto and Wound spirally about the roller with a permanent spiral set, and strips at `the sides of the screen, having guide Ways in which the edges of the screen engage, substantially as described.

3. In a Window screen, the combination of the roller, the screen wound spirally thereon, strips having guide grooves with which the edges of the screen engage, and a rigid frame extending across the lower end of the screen and a short distance up the sides thereof, substantially as described.

4. In a Window screen, the combination of the roller, the screen Wound spirally thereon, the strips at the sides having guide grooves on their inner edges with which the outer edges of the screen engage, and a rigid frame at the lower end of the screen, consisting of the cross bar L, the vertical end bars M secured to the ends of the cross-bar, and to which the screen is secured, substantially as described.

5. In a Window screen, the combination of the roller the screen Wound spirally thereon, the strips having guide grooves with which the edges of the screen engage, and the rigid frame at the bottom of the screen sliding in the grooves and composed of sheet metal bent around the edges of the screen secured thereto and comprising the cross-bar L and the bars M, substantially as described.

In testimony whereof I afiix my signature in presence of two Witnesses.

JEROME RICH.
