GHAUNCEY A. BATES AND WALTER W. HOBBY, OF WHITE PLAINS, NEW YORK.

WINDOW-SCREEN.

Specification of Letters Patent.

Patented Nov. 7, 1916.

To all whom it may concern Be it known that we, CHAUNCEY A. Barns and WALTER W. HOBBY, citizens of the United States, residing at White Plains, in the county of lVestchester and State of New York, have invented new and useful Improvements in lVindow-Screens, of which the following is a specification.

This invention relates to improvements in window screens and has particular reference to that class known as extensible screens.

The invention aims to provide a device of the above mentioned character, capable of self-adjustment to accommodate windows of varying widths, the screen being designed for vertical sliding adjustment upon the blind stop of a window and to retain itself in any desired position, whereby the manipulation of the upper and lower window sashes is provided for without any interference on the part of the screen.

Other objects will appear as the nature of the invention is better understood, the same residing in the construction, combination and arrangement of parts hereinafter more fully described.

In the drawing forming part of this application like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is an elevation of the outer side of the screen showing the same in applied position. Fig. 2 is an elevation of the other side of the screen removed from the window. Fig, 3 is a sectional view taken on line (0-64 of Fig. 2. Fig. 41 is a sectional view taken on line b-?) of Fig. 2.

A screen constructed in accordance with our invention comprising a main frame section 5, and laterally adjustable auxiliary side sections 6. The frame in its entirety may be constructed from any suitable material, preferably metal, the main section 5 being formed to provide upper and lower horizontal flanges 7, the latter in addition to forming guides to be received by the grooves 8 in'the auxiliary sections 6, are adapted to be grasped to raise or lower the screen when desired. The main section is provided with an enlarged central opening,

the edges of which are bent upon themselves to form the strips 9 beneath which the marginal edges of the wire fabric 10 are arranged and clamped in the manner shown.

The auxiliary sections 6 are mounted to s de p n t e Peter are c t e main tion 5 and have rearwardly projecting lugs 11 extending through elongated slots 12 in the side portions of the main frame 5, the lugs being provided with notches 13 which receive the free ends of a bowed spring 14, the latter operating to normally maintain the auxiliary sections 6 in extended position. The intermediate portions of the bowed springs 14 are secured to the main frame 5 in any suitable manner. The outer edges of the auxiliary sections 6 are formed to provide guide grooves 15 adapted to receive the blind stops or beads 17 on the window, whereby the screen may be adjusted vertically, and by reason of the sliding adjustment of the sections 6 and their tendency to normally assume an extended position under the influence of the bowed spring 1 1, it will be manifest that the screen will hold itself in any desired adjusted position. It will be further noted that the mounting of the screen is such that the upper and lower window sashes may be raised or lowered when desired without any interference on part of the screen. The lugs 11 are adapted to engage the end walls of the slots 12 upon the maximum adjustment of the auxiliary sections 6 thereby preventing any casual separation between the parts. The construc tion of the screen is such that it will accom modate itself to windows of varying widths. The inner edge of the auxiliary sections 6 are formed to provide the flanges 18 adapted to be grasped for moving the sections inwardly toward each other when it is desired to remove the screen from the window. The screen is extremely simple in construction, thereby reducing the cost of manufacture to a minimum, and one which is very efficient in use.

It is believed that from the foregoing description the nature and advantages of the invention will be thoroughly understood without requiring a more extended explanation and therefore the same has been omitted. However we desire to have it understood that various changes in the construction, and proportions of the various parts may be resorted to when desired as fall within the scope of the appended claims, without departing from the spirit of the invention.

What is claimed is 1. A window screen mounted for sliding adjustment and comprising a main frame and late a y adju table side sectiQH m ans.

for normally extending said sections, means for limiting the outward movement thereof, and the inner edge section forming a flange adapted to be grasped for moving the sec- I tions toward each other.

2. A window screen mounted for sliding adjustment and comprising a main frame and laterally adjustable side sections, spaced upper and lower horizontal flanges on said main frame, said sections being formed with grooves for the reception of said flanges, means for normally extending said sections, and means for limiting the outward movement thereof.

3. A window screen mounted for sliding adjustment, comprising a main frame and laterally adjustable side sections, lugs projecting from each of said sections through elongated slots in the main frame and slidably mounted therein, and a bowed spring 20 secured to the opposite sides of the main frame engaging said lugs to normally main tain said sections in extended position.

In testimony whereof we affix our signatures in presence of two witnesses.
