WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 435,797, dated September 2, 1890. Application filed Eeptember 10, 1888. Serial No. 285,015. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM I1. CLARK and WILLIAM J. CLARK, both of Salem, Columbiana county, Ohio, have invented a new and useful Improvement in \Vindow-Soreens, of which the following is a specification.

Our invention is an improvement in those gauze screens for window-openings which have one or two extension wings or slides to enable the screen to be fitted to anyopening.

Our improvement consists in novel features of construction, as hereinafter described and claimed.

In the accompanying drawings, Figure I is a perspective View of a window-screen embodying our invention. Fig. II is an end elevation of the upper portion of the same. Fig. III represents the upper portion of our sliding extension or wing. Fig. IV represents a portion of the screen on the reverse side to Fig. I,a part of the screen proper being shown broken away, so as to expose the guide-tongue and the stop.

In the following description the side of the screen presented in Fig. IV is called the front, and that presented in Fig. I is called the rear, of the screen.

1 represents the frame, and 2 the gauze filling or panel of the screen-body. The top and bottom front corners of the screen-body have each a rabbet 3, extending from side to side, 7 and having at its innermost angle a vertical inwardly-extending groove 4: and a horizontal inwardly-extending groove 5. Each of such doubly-grooved rabbets contains a pair of four correspondingly-formed slides 6, which are nailed, screwed, or otherwise firmly fastened to the wings or sliding extensions 7. S 9 represent, respectively, vertical and horizontal tongues on said slides, which occupy the said grooves 4 5. Both outward and inward play of said wings is limited by stops, which consist of pins 10, that, being driven horizontally into the substance of the frame 1, occupy horizontal slots 11 in the vertical tongues 8.

We claim as new and of our invention- The combination of the frame 1, having the top and bottom rails thereof formed with rabbets 3, extending all the way across the frame, and provided with vertical. grooves 4, extending all the way across the frame in the horizontal angles of the rabbets, and with horizontal grooves 5, extending all the way across the frame in the vertical angles of the rabbets, the wings 7, having top and bottom slides 6, formed with vertical tongues'S, and horizontal slots 11 in said tongues, and with horizontal tongues 9, and -the stop-pins 10, extending through the horizontal slots across the rails and guides, substantially as shown and described.

In testimony of which invention we hereunto set our hands.

WILLIAM H. CLARK. WILLIAM J. CLARK.
