WINDOW-SCREEN.

SPECIFICATIONforming part of Letters Patent No. 334,676, dated January 19, 1886.

' Application filed September 28, 1885. Serial No. 178,391. (No model.)

To all whom it may concern.-

Be it known that we, PETER PAULUS and HENRI FABER, both residents of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Window-Screens; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a perspective view of a portion of a window-frame provided with our improved fly-screen, showing the hinged portion of the screen opened and the screen drawn out to its full width. Fig. 2 is a front View of the same with the hinged portion closed and the frame drawn in to less than its full width, and Fig. 3 is a perspective detail view of one of the sliding sides of the screen and the means for adjusting the parts of the same.

Similar letters of reference indicate corresponding parts in all the figures.

Our invention has relation to that class of extensible window-screens in which the rabbeted or reduced ends of the top and bottom pieces of the frame-halves slide upon each other, the top and bot-tom pieces of one framehalf having longitudinal slots with which they slide upon set-screws projecting from the other top and bottom pieces; and it consists in the improved construction and combination of parts of such a screen in which the slots in the top and bottom pieces may be covered, so as not to admit any insects, and which may be permanentlysecured in the window-frame and still be capable of being opened, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A and-B indicate the frame-halves, the top and bottom pieces of which are reduced for a portion of their length, as shown at O and D, for the purpose of fitting upon each other. The end pieces, E and F, of the screens are provided with perforations for the reception of screws G, by means of which the framehalves are secured to the j ambs of the windowframe. The reduced portions 0 of the top and bottom pieces of the frame-half A are formed with longitudinal slots H H, through which project screws I I from the reduced ends of the top and bottom pieces of the other framehalf, B, the said slots sliding upon the screws, and the screws are provided with thumb-nuts J, bearing against the inner sides of the slotted portions, for the purpose of clamping them and adjusting them upon the screws. The frame-half'A is provided with a frame, K, which fits within the sides of the frame, and which is covered with net L, and this inner frame is hinged at its outer side to the end piece ofthe frame-halfswinginginward. Turnbuttons M are pivoted upon the screws, and serve to retain the hinged frame closed, and may be secured in their position by tightening the thumb-nuts. Strips N, of tin or similar sheet metal, are pivoted upon the screws at one end,and are of a sufficient length to cover the ends of the slots, which are left open by sliding the screen-halves out, the strips being turned from their resting-place in the rabbets of the top and bottom pieces of the frame B to the rabbets in the top and bottom pieces of frame A when the frame-halves are slid apart. It will thus be seen that the frame may be fitted into almost any size of window-frame, whereupon the end. pieces of the frame may be secured by the screws in the said windowframe, and whenever it is desired to have ac cess through the window the hinged frame of the screen may be swung inside.

We are aware that it is old to construct an adjustable window-screen composed of two sliding frame-halves, one of the said frame-halves having its top and bottom pieces formed with longitudinal slots and the other frame-half having its top and bottom pieces provided with screws, which project through the slots of the other frame-halt and have nuts upon their free ends, by means of which the framehalves are secured in their adjusted positions, and the said top and bottom pieces being formed with projections adapted to close the slots of the slotted frame-half when the screens are extended, for the purpose of excluding insects; and we are also aware that it is old to hinge one half of a screen to the end bar of an integral frame, and we do not therefore claim either of such constructions, broadly; but

What we claim as our invention, and desire to secure by Letters Patent of the United States, 1s 1 1. In an extensible window-screen, the conr binntion of a framehalt" having the ends of its top and bottom pieces reduced and formed with longitudinal slots, n h'anielmlf having the ends of its top and bottom pieces reduced and sliding upon the other reduced ends, and provided with screws projecting through the slots and having thumb-nuts, and strips of tin pivoted at their ends upon the screws between the reduced ends of the top and bottom pieces of the framehelves, as and for the purpose shown and setforth.

2. In an extensible window-screen, the combination of a frame-half having the ends of its top and bottom pieces reduced and longitudinally slotted, a frame-half having the ends of its top and bottom pieces reduced, and pro our own we have hereunto affixed our signatures in presence of two witnesses.
