AWNING.

SPECIFICATION forming part of Letters Patent No. 258,319, dated May 23, 1882, Application filed February 20, 188%. N0 model.)

To all lwhom it may concern:

Be it known that I, A. GUsrAE SAHLQvis'r, a citizen of Sweden, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Awnings, of which the following is a speeilication.

The objectofmyinvention is to provide cheap and convenient im proved means forraisin g and lowering awnings-such as are used for shading windows and stores-and uniformly folding and unfolding the awning-canvas automatically by such raisin g and lowering, respectively.

The invention consists in the combination of parts constructed as hereinafter described and claimed, with reference to the accompanying drawings, in whichi Figure 1- represents a perspective view of a partly-opened awning constructed according to` my invention, the canvas being removed. Fig.2 is a vertical section of the same with the canvas partly folded.-

Similar letters of reference indicate like parts.

A is the window-frame, the sashes of which are not shown.

B B is the ordinary U-shaped iron frame,to which the canvas is fastened, and the lower ends of which are hinged or pivoted to lugs a, secured to the frame A. From the horizontal bar B of the frame B B the ordinary canvassupporting cords, b, run overa roller, G, to which their inner ends are attached. The roller C is mounted in lugs or bearings D, attached to or at about the upper end of the frame A, and to which said roller C is attached one end of the operating-cord c, which thence runs down and underneath a pulley, E, bracketed to'or at the lower end of the frame A. The cords b and the cord c are wound upon the roller() in opposite directions, as shown in the drawings, so that the pulling ofthe cord c in the direction of the arrows I will unwind the said cord from the roller C, while at the same time the cords b will windupon the roller'G in direction of arrow 2, thereby shortening the distance between the rollerU and horizontal bar B of the awning-frame until the said bar is brought up close to the said roller. When so folded the frame B c, the following mechanism, to which, however,

I lay no claim, might be substituted:

Upon one end ot' the roller G is attached a conical wheel, d, gearing into a. similar wheel,l

c, on the upper end of a vertical rod, F, mounted in bearingsf upon the frame A, and upon the lower end ofthe said shaft F is another conical wheehf', gearing with a similar wheel,g,which is mounted upon a. crank-shaft, G, which latter may be arranged to operate either from inside or outside of the window.

In an awning intended to shade the sidewalk the vertical bars B of the frame B B should be omitted, and the horizontal bar B should he provided with end rollers arranged to run upon the ordinary inclined fra-m e-worl-i on which such awnings are supported.

H is the awning-canvas, attached with its forward edge at m to the horizontal bar B', and with its rear or inner edge at n to the upper edge of the frame A above the roller C. In order to fold the canvas H uniformly and keep it from being entangled o r extended to bag out in the wind, the said canvas is provided at suitable and preferably equal intervals with 1in gs h, which are sewed to the canvas and threaded on the cords b, so that, when the cords b b are wound upon the roller C, by the pulling of the cord c the rings h will slide together upon the cords b, between the roller C and the bar B', and consequently the portions of the canvas intervening between the said rings h will thus be tucked in equal folds side by side and held together between the said roller and bar.

It is 'evident that in lowering theframe B B the canvas H will be stretched out evenly upon the supporting-cords b b,

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The coubination of the canvas H and a stitteniugbar, B', attached to said canvas,with the supporting-cords b, operating-cords c, and roller U, said cords being secured by their ends to wind in opposite directions upon the roller C, so that the unwinding of the cord c will wind IOD the cords b, and vice versa, substantially as set forth.

2. In an aivning, the combination of the hin ge-frame B B', the roller C, the canvas-supporting cords b, attached with their ends to the frame B, and roller C, and the operating-cord c, Wound upon the roller C in opposite direction to that of the cords b, substantially as set forth. .c

3. In an awning, the combination, with the bar B', connecting the front ends of the can- Vas-supporting cords b, and with the roller C, and operating-cord c, the said cords b and c being Wound on the roller in opposite directions,
