WINDOW-SCREEN.

EEPECIPICATION forming part of Letters Patent No. 332,574, dated December 15, 1885.

. Application filed July 6, 1885. Serial X0. 170,792. (No model.)

To all whom it may concern.-

' Be it known that I, SAMUEL J. VANCE, a citizen of the United States, residing at Macomb, in the county of McDonough and State of Illinois, have invented a new and useful Improvement in Window-Screens, of which the following is a'specification, reference being had to the accompanying drawings.

My invent-ion relates to an improvement in window screens; andit consists inthe peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation of a window with my screen applied thereto. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a detail sectional view through the roller of the screen. Figs. 4. and 5 are detail views of the brackets for supporting the roller. Fig. 6 is a detailed perspective View of the roller-cap and the spring-rod, showing the details of construction of said cap and rod.

Arepresents a window-frame of the ordinary construction, to the inner side of the casing of which, at its upper end, are secured bracketarms B and B, which are arranged in a horizontal line with each other, and which extend outwardly and upwardly from the windowcasing. The bracket-arm B is provided with an inclined elongated slot, 1), and the bracket B is provided with a similar slot, 1), having an opening, 0, at its outer end to receive one end of the projecting journal of the roller 0. This roller is composed of the cylindrical casing a, a shaft, d,which extends longitudinallythrough the casing, and a coiled spring, 6, one end of which is secured to the shaft and the opposite end of which is secured to the casing, as shown. The shaft d has one end projectingbeyond the end of the casing, so as to provide a journal for the latter,and this proj ecting end of the shaftis flattened, as at f, and adapted to enter the slot 1) of the bracket-arm B. The end of the shaft d, adjacent to the reduced portion thereof, is rounded, as at g, and bears in a cap, D,which is secured in one end of the casing. This cap is provided with a central groove, h, on its inner side, and the shaft dis squared on its portion adjacent to the rounded portion 9, and adapted to fit in the groove in the cap when the shaft is drawn endwise, and thereby lock the shaft to the cap after the spring has been wound up and before the fixture is placedin position in the brackets. One corner of each of the notches i, which are formed by squaring the shaft, as described, is rounded off, as shown, so

as to prevent the shaft from catching in the when the screen is being groove-in the cap be hereinafter more fully wound up, as will set forth.

D represents a screen, which is formed either of cotton or wire netting, and is secured at 1ts upper end to the roller 0. To the lower end of this screen is attached a stick, F, the ends of which project beyond the sides of the screen, and are beveled on theirouter sides, as shown, these bevels extendinginwardly and upwardly so as to give the ends of the stick awedge shape.

G represents pins, which are secured to the 111- ner sides of the casing of the window, and project downwardly and outwardly therefrom, or in the opposite direction to the inclination of the bracket-arms. As here shown, two pairs of these pins are secured to the window-casing, one pair being at the lower end thereof and the other pair being on a line with the meeting edges of the sashes, and across the windowframe on its inner side,in aline with theupper pair of pins, is secured a strip, H, the inner face of which is on a line with the inner faces of the sides of the window-casing.

The operation of my iuventionis as follows: Owing to the inclined slots with which the bracket-arms are provided,the roller is caused to bear against the inner side of the windowfraine by its own gravity andthetension of the spring, so as to form a tight joint therewith. The ends of the stick F at the lower end of the screen catch under the pins G and bear closely against the casing, and thus stretch the window-screen tightly against the face of the easing,so as to prevent insects from entering the room between the screen and the windowframe. When it is desired to raise the screen, the stick is released from beneath the lower pair of pins,when the spring draws it up by rotating the roller and winding the screen thereon, the same as in the case of the windowcurtains,which are provided with spring-rollers now in common use. When the stick F reaches the upper pair of pins, it may be secured .thereto, and thereby serve as a screen for the upper sash or portion of the window,

or the screen may be entirely rolled up out of the way, if desired.

This screen is also adapted to be used in connection with doors, and may be stretched from the top to the bottom thereof, as here shown, or crosswise from jamb to jarnb, care being taken to have the slots in the brackets which support the roller inclined in the opposite direction to the pins which catch the wedge ends of the stick I am aware that it has been heretofore proposed to provide a windowsash with a pair of screens attached tothe top and bottom thereof, a pair of 'gravitating rollers journaled in brackets having inclined slots for the other ends of said screens, and friction-cords that support said rollers and wind upon them, causing them to revolve as the sash is raised and lowered, and draw the screens taut to cover the spaces above and below the sash, and this I disclaim.

I am also aware that it has been proposed to there will be no spaces between the edges of clined slots, and the pins on the opposite side from the brackets and inclinedin the opposite directionlfrom the slots of said brackets, of a spring-rollerjournaled in the slots of the brackets, a screen on said roller, and the rod F at the opposite end of the screen, said rod being adapted .to engage with the inclined pins, whereby the'screen is stretched tightly-across the frame, its sides being in contact with the sides of the frame, substantially as described.

2. The combination,with a=window or door frame having-the brackets provided withinclined slots, and theprojecting pinsontheside opposite the brackets and-inclined intheopposite directionto'the slots, wit-h the spring: roller journaled in the slots, of the screensecured to the roller at one end and having the stick-F at its opposite end, said stick having the projecting beveled en'ds adapted to-bear under the projectingpins, for'the purpose set forth, substantially as described;

In testimony that I claimthe foregoingas my own I have hereto aff xed my sig atnre in presence of two witnesses.
