SPECIFICATION forming part of Letters Patent No. 249,107, dated November 1, 1881,
Application tiled May 20, 1881. (No model.)
To all whom t may concern:
Be it known that LEUGENE H. ScHorIELD, of Bridgeport, in the county of Fairfield and State ot' Connecticut, have invented an Improved Window-Screen and Manner ot'Applying the Same, otwhich the following is a specitication.
The object ot my invention is to provide a simple and convenient form of window-screen and mode ot' applying it, which will admit of ventilation at both the top and bottom ot' the window at the same time, and which will not interfere in any manner with the operating ot' blinds or sash, so thatthey need notbe removed from the window during the entire season ot' mosquitoes, iiies, and other insects.
Figure lis an elevation of a common window, showing the upper sash closed with the screen C attached to the bottom of said sash, and the screen D attached to the window-frame. Fig. 2 is the same with the sash let down` so that the attached screen C rests on the window-sill. Fig.3 is a horizontal section of one side ot'window frame and screen C, just above the bottom rail of said screen, showing the construction and manner ot attaching the guide-pieces H to the screen.
A is the outside casing of the l'ramc. B is the upper sash. C is a screen of ordinary construction, attached to the bottom of the upper sash, being free to move up and down with said sash.
D is anarrow screen attached to that portion ofthe window-frame commonly called the blind-stop,77 and should extend across the top of the window and down to about the middle ofthe top rail ot' the sash when the latter is in position shown in Fig. 2. The inner face of this screen must be in close proximity to the outer face ot' the sash-rail, so as to ettectually exclude insects. The top and two sides of the screen being` attached to the window-frame, a simple fold or hem is sufficient for the bottom, or it maybe stiffened with a wire or thin strip of metal, butany considerable thickness at this point would interfere with the blind-Slat rod where outside blinds are used.
The lower sash (not shown in drawings) is free to move up and down, and may be left opposite the upper sash when in position ot Fig. 2, thereby secnrin g full ventilation ,both above and below, or it may be lowered to cut off as much otthelower ventilation as maybe desired. So the opening` at the top may be partially or entirely closed by the upper sash, or the sash maybe locked in the usual manner withoutinterfering with the screens.
The screen C is made half an inch less in width than the sash, so that it can be put in place without .removing the parting-strip G, Fig. 3, and a few inches less in height than the space below the upper sash, thus providing for ventilation at the top when the screen is down to the sill, and a chance to adjust the blinds by raising the screen, as in Fig. l.
H, Fig. 3, is a rabbeted piece, short enough to stand upright under the upper sash when raised, and litted to the screen and windowframe in the manner shown, and for the purpose otsupplying whatthe screen lacksin width and thickness, as it is not necessary or desirable to make the screen as heavy as the sash.
The screen C is inserted and attached to the bottom ot' the upper sash with screws, or in any other convenient manner, the half-inch mentioned above being divided, so as to secure a bearing of one-fourth of an inch at each side. One oftherabbeted slide-piecesH is now placed at each side ofthe window, as shown in Fig. 3. The screen is brought down to the sill between the rabbeted pieces, which are then secured to the screen in the manner shown. The screen is thus held in place against the' parting-strips by the slides at the bottom and the sash at the top, effectually excluding insects, while it is free to move up and down with the sash.
I am aware of the arrangement wherein the screens are attached to the bottom of the lower sashl and to the top ot' the upper sash, pockets being provided above and below the window for the screens when the sashes are closed; but in this case the house must be built for the screens rather than the screens for the house.
I am also aware that screens have been attached to the bottom of the upper sash and to the top of the lower sash. By this arrangement the window must be either entirely closed or open to the full extent, as anyinterm'ediate posi tion of either sash would leave an unprotected openingaboveorbelow. Byattachingtheupper screen to the window-frame the uppersash may be opened any required distance until thelower screen rests on the sill. Then, if more air is bottom of the said upper sash, being free to required, the lower sash may be raised to any move up and down with said sash, and the position, und the openings will always be proguide-pieces H, attached to each side of screen tected by the screens. C and fitted to slide in the grooves provided 5 Having thus described my invention, Iclaim for the sash, substantially as and for the pur- 15 ns new and wish to secure by Letters Patent pose specified.
