Q. KING. WINDOW SGREEN.

Patented May 4, 1886.

m MW UNITED STATES PATENT OFFICE,

QUINCY KING, OF COLORADO SPRINGS, COLORADO.

WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 341,334, dated May 4, 1886.

Application filed March 5, 1886. Serial No. 194,150. (No model.)

To all whom it may concern.-

Be it known that I, QUINCY KING, a citizen of the United States, residing at Colorado Springs, in the county of El Paso and State of Colorado, have invented certain new and useful Improvements in Window-Screens; and I do 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 appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a representation of this invention, and is a vertical section through a portion of a window with the screen and its fixtures. Fig. 2 is an inside front view of a portion of a window with the screen attached. Figs. 3, i, 5, and 6 are details of the different parts.

This invention has relation to windowscreens; and it consists in the construction and novel arrangement ofv parts, as herein after set forth, and pointed out in the claims.

In the accompanying drawings, the letter A designates the casing of the window-frame; H, the jamb, and M the strip.

B represents the sill, and D the screen, which is attached by one end to the roller V, and by the other end to the sash.

The screen may be connected to the upper or lower sash, both sashes being provided with rollers and screens, if thought desirable. Sometimes it is desirable to strengthen the screen by running threads or cords in the vertical direction therein, as indicated at v o.

The roller V is of cylindrical form, and is provided at one end with a brad or pin, k, which is driven into its end and forms the journal at this end of the roller, said journal turning in a suitable seat provided in the window-jamb or in thestrip. At its other end the roller is axially recessed, as at a, to re ceive the pin-bearing d, which is made flattened or wedge-shaped at the end which is driven into the jamb or strip, so that it will not turn. A spring, S, of spiral form is arranged around the pin-bearing,and is fastened thereto at one of its ends, as indicated at b. The other end of the spring is secured to the roller, as at c. The tension of the spring is such that when the sash is closed and the screen all wound upon the roller there will be little or no strain upon the latter, but when the sash is raised the tension of the spring will be increased, so that upon any movement of the sash in the direction of closing it the screen will be automatically taken up by the roller. At that end of the roller which engages the pin-bearing d is provided an adjustable cylinder or thimble, e, which covers the spring and forms a yielding section between the roller and piirbearing. The end of the pin-bearing projects through an aperture, 9, in the end of this thimble. That portion of the screen which is at this end of the roller is attached to the thimble, and as the thimble is not rigidly attached to the roller it will readily yield when the roller is put in position between its bearings. In this manner the screen and roller may be made to suit windows which differ to some extent in width. This construction also enables the roller to be readily put in position or removed therefrom.

Usually I provide a transverse strip, 71 to which the edge of the screen is attached, said strip to be secured to the sash-rail, and in order to prevent the tension of the spring from moving the sash when the latter is raised the strip h is provided with slide-fastenings Z, which may be readily moved outward to engage the jalnb or side strip of the windoweasing.

F represents an elastic stop, which consists of a strip of sheet metal bent in loop shape throughout its length and fastened by its lower branch to the sill; The upper or turnedover portion of this stop is designed to rise against the screen-roll and obstruct the crevice formed under the same when the screen is unrolled.

To cover the screen when rolled up, a cap, G, may be used, said cap having an upper portion, p, of partial cylindrical form, and a base, 9', as shown, said base or flange being provided with perforations for tacks or fastening-screws, whereby it may be secured to the sill of the window.

L represents a strip of metal or wood which is to be attached to the meeting-rail of one sash, and is cut on its free edge to conform to the section shape of the mullion and stiles of the opposite sash, so as to close the interval between the lights which is occasioned by raising the lower sash 0r pulling clown the upper one.

Having described this 1 invention, what I claim is The combination of the screen-roller having the axial recess in one end, the yielding thiinble 0n the roller, the pin arranged in the said axial recess and passing through an aperture in the sleeve, and the spring incloscd Within the sleeve, and having one end secured to the Z0 roller and the opposite end secured to the pin, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
