WINDOW-SCREEN.

SPECIFICATION formingpart of Letters Patent No. 726,851, dated May 5, 1903. Application filed December 20, 1901. Serial No. 86,629. (No model.)

To aZZ whom it may concern.-

Be it known that I,.JAcoB BIRMELIN, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Window-Screens; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

Myinvention relates to and its object is to 5 provide a window-screen which shall always be in place and ready for use and which when not in use shall be concealed, housed, and protected from the weather. I attain these objects by means of the devices and arrangement of parts hereinafter described and shown, and illustrated in the accompanying drawings, in Which--- Figure 1 is a side elevation of my device seen from a houseinterior, showing the window raised and the screen in operative position; Fig. 2, a central sectional edge view of the same with the screen concealed and with the hook hereinafter referred to engaged with the screen ready to lift the screen; and Fig. 3 is the same, showingthe sash raised and the hook and screen out of engagement with each other.

Like numerals of reference indicate like parts throughout the drawings.

In the drawings, 1 is a window-casing in which slides a window-sash 2. Through the Window-sill 3 is a narrow vertical opening 4 of the same width as and immediately beneath the bottom rail of the window-sash. In the wall beneath the window-sill is a pocket or chamber 5, which ordinarily extends to the floor of the room.

6 is a window-screen composed of wire-cloth mounted at its margins in the fold of doubled sheet-metal strips 7. If preferred, the wirecloth may be in two equal pieces, the vertical meeting edges of which may also bemounted in the folds of like sheet-metal strips 8. The

vertical outer margins of the screen may when raised rest snugly against the sides of the window-frame, or, if preferred, they may slide in grooves formed in the side of the windowscreen concealed in the pocket,

frame. When the screen is lowered to its lowest point, it passes through and is suspended from the window-sill in the pocket or chamber 5 by narrow horizontal flanges 8 011 the top of the metal screen-frame.

The lower rail of the sash is grooved along its bottom, as at-9, to receive the top of the screen. The lower railof the sash, on its inner vertical side midway of its length, has a mortise leading into the groove 9. [A plate 10, secured to the sash, covers the mortise and has on its inner sidelugs 10",, in which is pivoted a hook 11. This hook at bottom has a catch which is adapted to engage an opening 12 in the topof the frame of the screen. The hook at top curves outwardly, forming a convenient finger-piece, by means of which the sash'may be raised and lowered.

The operation of my device is as follows: When the window-sash is lowered and when no screen is needed, the screen hangs suspended from the top margins of the opening 4 by the narrow horizontal flanges 8 formed on top of the frame of the screen. When it becomes necessary to raise the window, when no screen is required, the operator presses the finger-piece ofthe hook 11 inwardly, thus disengaging the lowerend of the hook from the screen, and pulls upwardly "on the fingerpiece, thus lifting the sash and leaving the When it is desired to raise the window and to close the opening with the screen, the finger-piece of the hook is drawn outwardly. Now the screen is engaged by the hook, and the screen may be lifted with the sash. When the sash and the screen are raised, the screen may at any time be lowered or dropped by simply pressing inwardly on' the finger-piece, thus disengaging the book from the screen. It will be seen that the screen is always in place ready for use, that when not in use the screen is housed and stored away from the weather, and that no matter how high the window-sash is raised the screen exactly fills the opening.

Having described my invention, whatv I claim, and desire to secure by Letters Patent, 1

A window-frame, a pocket beneath the frame, a sill for the window-frame having a slot which leads into said pocket, a sash movable in said frame, a screen adapted to slide :0 and lowered the arrangement being such that outward pressure on the finger-piece will engage the hook with the screen and such that inward pressure on the finger-piece will disengage the hook from the screen.

In testimony whereof I affix my signature :5

in presence of two witnesses.

JACOB BIRMELIN.
