WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 642,471, dated January 30, 1900. Application filed September 25, 1899. Serial No. 731,692. (No model.)

T0 @ZZ .whom it may concern.-

Be it known that I, THEoDoRE J. P. MAUS, of the city of St. Louis, State of Missouri,phave invented certain new and useful Improvements in Window-Screens,of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part'hereof.

My invention relates to window-screens;

'and it consists of the novel construction, com- Figure 1 is a frontelevation of a window,

showing my complete invention placed in position therein. Fig. 2 is a horizontal sectional view of the window-screen. Fig. 3 is an enlarged vertical sectional view of the screen with parts broken away, showing its connection with the bottom rail of the Window-sash. Fig. 4 is a sectional perspective view of a portion of the window-screen. A

In the construction'of my invention I provide two frames 1 and 2, each consisting of vertical strips 3 and a horizontal strip 4, one located at the top and one at the bottom. Their ends 5 are supported by an angularlybent metallic strip 6, which is arranged to lit in slots 7, arranged in said horizontal strips a short distance from the end 5 thereof. In each of the vertical strips 3 is formed a groove 8. This is for the purpose of allowing said strips to be placed over a guide-strip 9, which is of the ordinary construction and secured to the inner vertical surface ofthe windowframe 10. (See Fig. l.)

The adjusting feature of the invention is provided by the arrangement of the horizontal strips and each of which is constructed with a dovetailed groove 11. (See Figs. 3 and 4.) On their inner surface and in one of the strips is placed a block 12, which is generally about one inch in length and is arranged to iit within (see Figs.- 3 and 4.)

The horizontal strips at the top and bottomL are exact duplicates. The vertical strips 3 (see Fig. 2) are composed of two parts 15 and 16, and between the same is fastened one end 17 of the screen 14, and the other end of the screen is fastened in any desirable manner to the angular strip 6. The parts 15 and 16 each contain a portion of the groove 8, and when the screen is placed between the same they are secured together in any desirable manner.

In order to provide a tight joint upon the upper and lower horizontal strips to prevent insects from passing between the upper horizontal strips and the horizontal bar 18 of the window-sash, place a strip of thin material 19, such as tin, dac., and secure the same in any desirable manner to the outer portion of the strip, as shown at 20, and the same is passed over the top and extended downwardly on the inside, as shown at 21. On this side is also secured in any desirable manner to the inner portion of the strip 4 a strip of like material 22 and passed over the strip 19 and extended around the outer surface, as shown at 23. This arrangement will allow both of the strips in connection with the groove 11 to telescope one within the other and yet provide'an even appearance on all sides. The material 22 when placed in position within the window is brought into direct communication with the side 24 of the lower bar 18 of the window-sash, thus making a tight joint.

These strips 19 and 21 fit so closely around serve the double purpose of retaining the desired adjustment of the screen and of forming a close joint with the sash of the window at the top of said screen and with the window-frame at the bottom.

The arrangement of the two screens of both sections is such that at the point 25 (see Fig.

. strips of the screen.

2) they will be brought close together, so as to also prevent any insects from passing between said screens.

The angular strips (3 are constructed of thin lightvmaterial and of small design, so as not to obstruct the free passage of air through the screen and also to present a neat appearance.

The operation of my invention is as follows: I first secure to the window-frame l0 the s'trips 9. I then place the screen within the .window and adjust the same sidewise, bringing the grooves 8 in communication with the strips 9. This I do by pressing outwardly upon the vertical strips 3 of each screen. The same is held in this adjust-ment by the tight fitting of the metallic strips 19 and 22, and the same will be in readiness to be raised or lowered upon the guide-stri ps 9, as desired. The bottom Window-sash is raised so as to bring the cross-bar 18 at its highest point and will communicate With the top` horizontal This screen may also be made of any desirable height, so as to operate as described no matter at what height the lower sash may be placed.

I claim- 1. In an adjustable Window-screen, horizontal strips composed of two parts slidingly secured together and having a metallic strip attached to each of said parts, said metallic strips fitting closely around said parts, one above the other, substantially as specified.

2. An adjustable Window-screen of two sections, having horizontal strips composed of two parts in each of which is a groove, a guide-block rigidly held in one of said grooves and adapted to slide within the groove in the other section, and a metallic strip attached to each of the parts forming said horizontal strips and fitting closely around said strips, one over the other, substantially as specified.

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