Application led July 31, 1914. Serial No.. 854,385..

To all 'whom t may concern Be it known that I, Viro A. QUAGLIANO, a subject of the King of Italy, and a resident of East Boston, in the county of Suffolk and State of Massachusetts, have in vented a certain new and useful Improvement in vvindowcreens, of which the following is a specification, reference being had to the accompanying drawings.

The chief object of this invention is to provide simple, inexpensive and eflicient means for readily attaching screens to, or for removing them from, ordinary windows, and my said improvement consists mainly of electro-magnetic means for holding Such screens in their operative positions in the window frame. Incidentally, I have also improved certain details of construction of such screens and their bracket supports.

My said improvement is embodied in the screen shown in the accompanying drawing, Figure l being an elevation of a window casing fitted up to receive and support a screen of my improved construction. Figs. 2 and 3 are, respectively, reverse and front face views of my improved screen, and Fig. 1 is an edge view of said screen. Fig. 5 is a perspective view of one of several corner brackets, or angle plates, which I provide at the corners of the window casing, and Fig. 6 is a similar view of a bracket provided at or near the vertical center of the window casing, to support the upper portion of the screen when the latter is used with the lower half of the window, and to support the lower portion of said screen when with the upper half of the window, as I will explain in detail later on.

Referring to these drawings, the letter a: indicates a window casing of ordinary construction, and the letters Z2 and c indicate, respectively, the upper and lower slidable sash. F iXed in position at the four inner corners of the said casing are angular plates CZ having, preferably, lateral rib or plate portions Z which may be secured to the casing by screws or otherwise. At the middle of the height of the said casings I secure oppositely disposed horizontal plates e which, as here illustrated, are provided with a rib e which may be screwed to the casing, also with a plate e2 which lies in the same vertical plane as the plates l above referred to, all of the described plates being preferably formed of Soft (so called Swedes) iron.

The window screen is denoted as a whole by the letter f, and'it has mounted in each of its four corners thin plates g of iron which have been magnetized to such a degree that, when the Screen is placed in operative position in the window casing (that is to say, with its plates g in contact with the plates cl and with the plates e2), the screen will be held in its operative position by reason of the magnetic adherence (coherence) of the screen plates with the casing plates. AWhen however it is desirable, or necessary, to remove the screen it may be done by forcibly Separating the cohering plates; handles h. for that purpose being secured to the screen vat the opposite Sides of its frame, as best seen in Figs. 3 and l of the drawings. When the screen is used with the lower half of the window, the upper corners of said screen underlie the plates e but when the Screen is used with the upper half of the window, the lower corners of said screen rest upon said plates-e.

It will thus be seen that no locks, latches or catches, are required to retain the screen in its operative positions, and as a further advantage, the described magnetic contact of the engaging plates holds the screen frame so close to the window casing or stop bead as to prevent the entrance of iiies, mosquitos, and the like pests, and alsoprevents the rattling of the screen.

While I .have particularly described the magnetized plates as mounted upon the screen, it will be obvious that said magnetized plates would be equally efficient if they were secured to the window casing, and the cooperating iron plates were mounted on the Screen frame.

. Having thus described my invention, I claim as new and wish to secure by 'Letters Patent zi l. In combination with a window frame, of angular metal plates having ribs for attachment in the corners of the frame, and a screen frame having magnetized plates fixed to its corners adapted to cohere with the plates carried by the window frame.

2. In combination with a window frame,

of angular metal plates having angularly to cohere with the respective corner plates arangefd ribs for attachment in each corner and intermediate plates.

o the rame, intermediate plates vertically spaced :from the corner plates and fixed to VITO A' QUAGLIANO' the frame and having horizontal ribs, screen l/Vitnesses: Y frames having magnetized plates carried by FRANK H. ALLEN, their upper and lower corners and adapted Ensim P. GRUNERT.
