ROLLING SCREEN.

Specification of Letters Patent.

Patented Nov. 1, 1921.

Application filed February 26, 1917. Serial No. 151,016.

. To all whom it may concern:

Be it known that I, JULIEN A. BRIED, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented a new and useful Improvement in Rolling Screens, of which the following is a specification and a which is illustrated in the accompanying drawings. Y Y I My inventlon relates to the improvement in rolling screens as applied towindows and other openings for the keeping out of flies and insects, and has for its objects the production of a rolling screen of simple construction easy to install and which will be extraordinarily tightly stretched when in position over the window opening and also effectuall sealed at the edgesagainst the entrance 0 insects, without the necessity of running the edges of the screen in a groove.

I attain the objects outlined above by thev device illustrated in the drawings accompanying this specification in which Figure 1 is a perspective view of a window casing as seen from the inside of a room and shows a rolling screen of my improved construction in position with the screen rolled up.

Fig. 2 is a-larger View of a vertical cross section of the device with the screen pulled down to cover the opening.

Fig. 3 is a cross section taken through the line a, a of Fig. 1 and shows the screen fabric seated at its edges and overhanging arched strips secured to the casing at both sides.

Fig. 4 is a similar view to Fig. 3 and shows a variation in the form of the arched seating strips permitting a greater overhang of the screen edges with a given width of fabric.

Fig. 5 is a view of the tension lever i'n locked ,position.

A clear understanding of the improvement embodied in my rolling screen will be had upon a more detailed reference to the drawings as follows. In Fig. 1 the screen carrying roller. 2 is shown positioned at the inside upper part of a window (the sheet metal dust casing 16 and the regular window shade roller 15 and its brackets 18 all shown in Fig. 2 being omitted to show more clearly the novel features of my invention.) The screen fabric 1 is attached by its upper edge to, and shown rolled up on, a spring actuated roller 2. This roller is secured in place on the. window casing by the brackets 3, 3' and is a common spring shade roller (preferably of the metal variety) with the exception that it dispenses with the usual pawl (to hold a shade at various heights) and has a gear wheel 4 secured to one end.

The

brackets

3, 3 are similar to the,ordi-' nary shade roller supporting brackets adapted to rotatably support the roller and hold the rewinding spring at any desired tension. I

The screen fabric 1. which may be of light woven wire though I prefer a painted or water-proofed cotton cloth screenjabric on account of its greater flexibility, has a stick 5 attached to its lower end, with several metal eyelets depending therefrom adapted to engage with the sill plates 7 to securely hold-it when the screen is pulled down.

After pulling down the screen and securing it in place the toggle tension lever 8 is pushed upward to force the short rack on the upper end of the rod 9 into engagement with the gear wheel 4 on the end of the roller to forcibly turn it and cause great tension in the fabric, Fig. 5 showing the locked position of the tension lever 8 when pushed upward.

. On each side of the window casing is secured a strip 10, preferably of wood, projecting a short distance from the surface of the window casing and against which strips the screen fabric rests when pulled down.

The strips 10 are sprung away from the surface of the window casing in the center before securing them firmly in place so as to form convexly arched seats; as clearly shown at 12 in Figs. 1 and 2; and against whichthe screen fabric tightly seats itself along both edges when forcibly stretched .with the tension device as described.

The screen fabric would seat itself against the arched strips through the screen tension produced by the action of the spring roller alone, but the tension of the ordinary spring roller would not cause as snug a seat on the strips as the very great tension produced by the rack and pinion device shown. In fact with this or a similar tensioning device the roller need not be spring actuated at all in so far as this feature of my invention is concerned and the fabric could be rewound by any other desired means.

To assist in making an insect tight joint along the edges when the screen is pulled down, I also allOW the fabric to overhang the arched strips as shown in Figs. 3 and 4 at 11, the greater overhang shown in Fig. 4 bein due to the seating portion of the strips being placed farther inward from the edge of the window casing.

The strips 10 instead of being sprung to an arched condition and nailed to the edge of the window casing, may if desired be formed to the required curve and attached to the face of'the casing at the edge of the window opening, but the method described of springing the strips to the arched form is simpler.

At the upper edge of the window opening is secured another strip 13 in Figs. 1 and 2. This strip'projects sufliciently to allow for the thickness of fabric when rolled up on the roller and provides a seat against which a portion of the fabric bears across the width of the window opening at the top when the screen is pulled down and forms an insect seal across the top of the window opening.

The lower ends of both arched strips are notched at 14 Figs. 1 'and2, one half the thickness of the stick 5 attached to the lower end of the screen, to allow the fabric to come in contact with the strips just above that point.

Fig. 2 is a vertical cross section of the screen when pulled down and shows the position of the screen roller in relationto the standard shade roller, the latterbeing shown at 15 and it will be observed thatmy screen fabric sheet- 1 pulls down between the regular shade roller 15 and the windowcasing and is also narrow enough to come down between the end brackets 18 ordinarily used.

to support the shade roller. At .16 in the same figure is shown in cross section a metal protective casing almost surrounding the roller screen to protect it against dust when rolled up; the dust casing may be supported ,on the end brackets 8, 3', or on the window casing or both. At 17 is indicated the actuating or rewinding spring within the screen roller 2, but no importance attaches to any particular construction'of' this feature, for an common spring shade roller may be used.

t might be mentioned at this point that if desired my screen can easily be adapted to cover but part of the window opening by arranging a stop piece across the opening at the desired point and securing the stick 5 at the lower endof the screen, to the stop piece instead of to the still.

Having thus descrlbedmy'lnvention it will be seen that I have provided aroll-ing window screen of simple construction which is sealed at the edges by seating itself. tightly against arched stripsjattached. to the window casing and is easily applied to the inside of a window casing just above and without interference with the. regular shade roller and also, that while I have shown and described a te sioning device whichacts on the be used and Salli acting on the roller as shown in the drawing 7 I feel entitled to cover in my claims any method of manually and forcibly tensioning a roller screen apart from a spring within the roller and also an arched or curved seat at the edges of an opening used with any kind of a screen whether on a roller or simply stretched over the opening, and likewise these principles if applied to shades instead of screens as I believe them to benewand useful in either connection.
