WINDOW-SCREEN FIXTURE.

SPECIFICATION forming part of Letters Patent No. 391,106, dated October 16, 1888.

Application filed June 28, 1888. Serial No. 278,493.

To aZZ 2072 0712 it may concern.-

Be it known that I, EDMUND H. AMBLER, of Beatrice, in the county of Gage and State of Nebraska, have invented a new and useful Improvement in \Vind'ow-Sereen Fixtures, of which the following is a specification.

The object of my invention is to provide a set of fixtures to adapt any window to receive a screen of the usual construction, which screen shall not interfere with the raising and lowering of thesash, but may be conveniently taken out and replaced for opening and closing the outside blinds.

It consists in a set of disconnected and rabbeted bushing strips adapted to tit in the grooves in which the sashes slide, and pr0- vided with fastenings for securingthe screen therein, as will be hereinafter fully described.

Figure 1 is a front view of the inside of the window-frame provided with my improvement. Fig. 2 is a horizontal section through line a; m; Fig. 3, a vertical section through line 3 y; and Fig. 4, a perspective view of the bushing-strips on a reduced scale, and showing the said strips in position to be assembled to form a supplementary frame.

A is the window-frame, and B B its two sashes,which slide, as usual, in the two grooves a a in the sides of the frame.

0 is the screen, which may also be made of the usual construction, as an ordinary rectangular frame, provided with a netting of gauze-wire.

D D and E E are four bushing-strips, which, together, form asectional supplementary frame that receives and holds the screen and is seated in the grooves of the frame at the end of one of the window-sashes. These bushing-strips are made of a thickness corresponding to that of the sash, so that they fit in the grooves in which the sashes slide. These strips are each provided with a projecting flange, d d and e e, on their outer edges, formed by rabbeting the strips, which flanges on the top and bottom strips run the full length of the strips, and on the side strips are shorter by the width of the flange on the top and bottom strips, upon which they rest. The top strip, D, is provided with lips or cleats b on its inner face, which overlap the edges of this strip and form locking-lugs, behind which the top edge of the screen is seated and secured, and the bottom strip, D, is provided with a button or catch, a, which may be turned to lock the lower edge of the (No model.)

screen after it is seated in the rabbct of the strips.

In adapting my invention to the windowframe the horizontal bushing-strips are adapted in length to the width of the window frame-i. 0., from the inside of one groove to the inside of the other-and the side strips are made of a length to completely fill the space in the side grooves below the upper sash, abutting at the top against the upper horizontal strip, D, and at the bottom against the lower horizontal strip, D, the side strips, E E, and ends of horizontal strips D D being so grooved as to admit of said cord or chain working without interference when frame and screen are applied to upper part of window-frame. Thestrips thushold themselves in place and form a seat inside the flange, which permits the screen to be placed laterally therein, and secured by the lips or cleats b at the top and the button or catch 0 at the bottom, the screen and strips resting in the plane of the sash, so as to permit the other sash to be raised or lowered without interfering with its movement.

This screen may readily be taken out and replaced without any change or readjustment of the bushing-strips, and the latter with the screen may be placed in the groove below the upper sash or in the groove above the lower sash, as may be desired.

I am aware that a window-screen has been set in a rigid supplementary frame, as shown in Patent No. 268,101, and I do not claim this construction.

Having thus described my invention, what I claim as new is The combination, with a window-screen, of a set of four disconnected rabbeted bushingstrips, D D E E, made each of the width of the sash-groove, the strips D D being arranged horizontally and having their opposite ends seated in the sash-grooveson the opposite sides, and the strips E E being arranged vertically and having their sides seated in the sash-grooves and their ends abutting against the horizontal strips, and fastenings, substantially as described, for holding the screen in the rabbct of the strips, as and for the purpose set forth.

EDMUND H. AMBLER.
