WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 231,649, dated August 31, 1880,

Application filed July 12, 1880. (No model.)

To all whom it may concern:

Be it known that we, ALLEN M. BURRELL, ALPHONSO R. MINER, and J. W. Bones, of .Oanisteo, in the county of Steuben and State of New York, have invented certain new and useful Improvements in Window-Screens; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

Our invention relates to an improvementin window-screens; and it consists in attaching the roller, around which the screen is wrapped or unwrapped as the window-sash is lowered or raised by means of suitable brackets or hearings, to the lower end of the sash, and then connecting to each end of this roller a wire or cord which has its upper end attached to a tension-spring, as will be more fully described hereinafter.

The object of our invention is to attach a screen to one or both window-sashes, so that as the sashes are raised or lowered the screen will be made to cover the openings for the purpose of keeping out flies and insects of all kinds.

Figure l is a front elevation of our invention. Fig. 2 is a vertical section of the same.

A represents a window-frame, and B B the sashes. Secured to the lower end of the lower sash are the two brackets O, of any desired shape or construction, and in which the roller D is journaled. Secured to this roller is the upper end of the screen F, which screen has its lower end securely fastened to the windowframe in any suitable manner. This screen may be made of mosquito-bar, wire-netting, or any other suitable-material, and is of sufticient width to nicely cover the opening which is made by raising the sash for the purposeof keeping out flies, mosquitoes, and insects of all kinds. A

Each end of the roller is provided with a suitable pulley, around which is wrapped the lower end of a wire, cord, or chain, G, the upper ends of which wires, cords, or chains are attached to the tension-springs I, which are fastened inside of the upper part of the frame. As the sash is moved upward the wires G are wound upon each end of the roller at the same time that the screen is unwound. As the sash is lowered the wires cause the roller to revolve, and thus roll up the screen. It the sash is being raised, the screen is unrolled, so as to cover the entire opening that has been made by the sash, and as the sash is lowered. the screen is wrapped around the roller, so as to be entirely out of the way.

Fastened to the inside lower end of the sash is a suitable board or protector, O, of any suitable material, which projects over the top of the roller so as to prevent any dirt, dust, or other substance from getting inbetween the screen, as it is wrapped upon the roller, and the sash. As the sash is being lowered the springs are stretched as the wires, cords, or chains are wrapped upon the roller, and this tension, as the sash is being raised, serves to assist in raising the sash upward. By the use of these springs all necessity for guidingcords, which extend from top to bottom of the frame and are wrapped around the roller, is done away with.

We are aware that a single coiled spring has been used in connection with the roller of a window-screen, and this we disclaim. In our screen the roller is journaled in brackets that are secured to theinside ot' the lower end of the sash, so that the roller is carried up and down with the sash, and causes the wires G to wrap and unwrap upon the roller at each end.

Having thus described our invention, we claim- In a window-screen, the combination of the lower sash, B, the two brackets O, secured to said sash, roller D, the two cords or wires G, which wrap around the two ends of the roller at their lower ends, and the springs I, substantially as shown.

In testimony that we claim the foregoing we have hereunto set our hands this 5th day of July, 1880.
