Letters Patent No. 96,363, dated November 2, 1869.

'IMPROVED WINDOW-SCREEN.

The Schedule referred to in these Letters Patent and making part of the same To all whom t't may concern:

Be it known that I, JAMES' A. THORN, of Chicago, in the county of Oook,'and State of Illinois, have invented an Improved Screen for Windows; and I do hereby declare that the following is a full, clear, and

exact description thereof, which will enable others` Figure 2, a perspective representation of the same,

removed from the window. v

This invention relates to an improvement in that class of wndow-screens which may be adj usted to suit window-frames of different widths; and

Its nature consists in attaching to the bottoln and top of one of the screen-frames, guide-strips, which have tongues running in 'grooves formed in the top and bottom edges ofthe other frame, andin fastening metal plates to the frame in'w-hich the grooves are made, to llthe spaces between it and the window-sill and sash, as hereinafter clearly shown.

G D E represent the inner ,fra-ine, which is made of wood, inthe usual manner, and provided `with slots, P, through which screws, N, are pnt, to holdl the frame C D E to a frame, H G. F, when the frames are adjusted to a window-frame, as shown at g. 1.

The gauze or wire cloth L is placed .on the outer sides ot' the flames, and held in place'by means of small strips of wood, M,`fg. 3, driven i'to grooves extending around the outer sides ot said flame-s.

Nothing,- however, is claimed in theconstruction so far set forth, as adjustable frames have been before used.

In order soto hold the two frames together that they will remain parallel to each otner, and run easily, I attach a strip, K, provided with a tongue on its inner side, to the top edge of rail D of theinueri-ame, and attach a strip, J, zalso, provided with a tongue, to the lower rail E, said strips extending over the edges ot' the rails G H of theouterframe, and the tongues f, running in groo 'es lh, so hold the flames that the StilesA FO will always remain parallel, f

lThis is not the case where the screws N are wholly relied upon to hold the frame in place; consequently there is considerable trouble experienced in adjusting the screen to the window-frame `in the latter case, which is not met in' setting my improved screen.

In order to till the space between the rail G and sash B, and the space between the rail-H and sill Z, I fasten, by screws or otherwise, thin metal plates, I, as shown at figs. 1 and 2,v thus preventing the possibility of insects passing through. y

All that is required' to adjust the screen to the window-trame is to raise the sash B, set the screen under it, and draw the flames apart to reach the jamb casing, then fasten the' set-screws N., and allow the sash to rest on lthe top of the screen, as shown at tig. l.. Having thus described in v invention,

What I claim, and desire to secure by Letters Patentpt' the United States, is

screens, the guide-pieces K J, provided with tongues f running I, said parts being lused to facilitate the` adjusting of the flames C DE and F G H, and shut the space 'H and sill Z, as described.
