IMPROVED ADJUSTABLE WINDOW-SCREEN.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, DANIEL N. HURLBUT, of Ghicago, in the` county of Cook, and State of Illinois, have invented a new and useful Improvement in Adjustable Window-Screens; and I do hereby declare and make known that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and the letters and figures marked thereon., which form part of this specification. i

Mysaid invention vrelates to that class of windowscreens which is const-ructedof two separate frames, suitably7 covered, arranged side by side, and having a sliding movement upon each, so as to cause the window-screen to shorten or lengthen, and thus adapt the same to different windows of different widths, which sections or frames are connected Aby means of a cord and spring, in such a manner as to press the ends of the screen against the sides of the window-frames, and thus canse the screens to remain in any desired position, either at the top or bottom, or at any intel'- mediate point, as' preferred.

My said invention consists iu the employment of bars at that part -of the screen where each section of the frame overlaps the other, to hold the wire or gauze vof 'each screen close up against the end of the frame of the other section, so as eectually to prevent the windt-'rom blowing the gauze, or wire back, to leave a space throughwhich insects might enter.

`To enable those skilled in the art to understand how tol construct and use my said invention, I will proceed to describe Athe same with particularity, making reference, in so doing, to the aforesaid drawings, in Which- Figure 1 represents a front view of my improvemeut in use;

Figure 2 is a vertical transverse section, taken at :z: in ig. 1, looking to the right; A

Figure 3 is a similar section,at y, in fig. 1, looking to the left; and

Figure 4 is a top view of the adjustable screen. Similar lettersof reference in the several yfigures denote the same parts of my said invention.

A and B represent the frames, on which wire or gauze screen-cloth C is fastened.

These frames are made so that theyslide past each other, so that they can be adapted to windows of different widths, and it is accomplished by attaching to' the top and bottom ofthe frame B, metallic strips D, which extend out sudiciently far for the edges thereof, which are turned at right angles, as shown in figs. 2 and 3, to embrace the edges ofthe frame A.

The frame A will slide back and forth between the plates D, and thus adapt the screen to windows of different widths.

E represents au elastic cord, or band, one end of which is attached to the frame B, as shown in lig. 1, while the otherend is attached to the frame A, in

such a manner as to constantly press said frames Y between the wire, or gauze, on the frame B, and.

the end-piece J of the frame A. To close that space and make the screen tight, so that no insects can pass through it, I place a cross-piece, K, across the frame B, in such a manner that it keeps the wire, or gauze on the frame B pressed against the end-piece J ofthe frame A.

As the end-piece J would not always be in the same position relative to the frame B, on account of the screen being placed in windows of different widths, the cross-piece K'is adjustable, so that it can be moved to different parts of the frame B. The crosspiece K may be made of any suitable ,material that would serve the purpose of keeping the wire, or gauze pressed against the end-piece ofthe frame A, as above described. K

I also put pins, or movable bolts O in those parts of the flames A and B that are pressed against the window-frame; and I also use set-screws P, which pass through one frame and set against the other, to hold the frames in place when they are set in a window, and the pins, or bolts O pressed into the frame, or casing thereof.

The pins O and set-screws P take the place of the spring E now in use, to fasten the screen more permanently into the window, so that it cannotbe pushed out by children, and, besides, it obviates the objections to springs ou account of' their liability' to become weak and useless after they have been used awhile.

AO' latins.

Having thus fully described theconstruction and operation of my invention,

What I claim, and desire to secure by Letters Patent, is

1. 'lhe combination of the cross-piece K with the frames A and B, when arranged and operating in a Witnesses L. L. GOBURN, J. L. COBURN.
