,l WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No, 242,180, dated May 31, 1881.

Application led March 30, 1881.

l To all whom 'it may concern:

Be it known that we, WARREN S. BARTLE and JOHN E. STUART, both of Newark, county of Wayne, State of New York, have invented certain new and useful Improvements in Window-Screens, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specilication, in which- Figure l isa perspective view of a windowframe with ourimproved screen applied. Fig. 2 is a vertical transverse section through the same. Fig. 3 represents a vertical section through a part ot' the window-frame showing from the inner side the relation of the screenframe thereto. Fig. 4 is a perspective view of the screen removed from the window.

Our invention relates toa novel construction of the screen-frame, whereby it is adapted to be readily applied within-the groove for the sash when the latter is raised, and to snugly close the opening withoutthe aid of adjustable or removable parts; and it consists in making the frame of a width corresponding to the width of the lower sash, or of the openings therefor in the window-frame, less the amount of projection of one of the stops or strips forming the groove for the sash, so that when one side of the screen-frameisinserted in the groove for the sash on one side the other side will pass by the projecting stop or strip on the opposite side of the window-frame, and in providing said screen-frame with a strip flange or flanges for spacing it or causing it to overlap evenly the outer stops or guide-strips and for holding it out snugly against the same, as hereinafter described.

In the accompanying drawings, A represents the window-frame; A', the sill thereofinclinin g outward; B, the lower sash, and a c the stops or strips forming the grooves or ways in which said sash moves, said parts being constructed and arranged in the usual or any preferred manner.

C represents the screen complete, removed from the window in the perspective view, Fig. 4.

The frame is composed of the vertical side strips, c c2, and the top and bottom strips or bars, c3 c, neatly framed or secured together and giving a width of frame equal to the width of the sash B, whose place it is designed to (No model.)

occupy, less the amount of projection of the guide-strip a or c on one side of the frame A, thereby' adapting it when one side of the screenframe is placed iu thc sash channel or groove on one side to allow the opposite side to pass or more. by the stop or strip on the opposite side of the window-frame. The side and top bars, c c2 c3, of the screen-frame are of reduced thickness as compared with the sash-frame, while the lower bar, c, is, by preference, made of suticient thickness to about snugly lill the sash-groove, thus making it project beyond the inner face of the side bars,c c2, as shown. The upper horizontal frame-bar, c3, has a rabbet formed in its upper face, or a strip may be rigidly secured to its outer face and made to project above the barca, as shown at d. This strip A or ilange is made shorter than the bar c3, and of a length adapting it to tit snugly between the outer strips, c a, between which it rests when the screen-frame is in place. The frame projects equallyon each side beyond the ends of the strip d, and the latter beingformed upon or secured to the outer face of the frame-bar c3, as shown, when the strip d is forced outward between the outer stops, a, the sides of the screen-frame will rest against and overlap evenly the inner faces of said strips or stops a, as shown in Fig. 3, when the sash being let down inside of the strip el, as shown in Fig. 2, the top ot' the screen-frame will be held snugly out against said stops or strips. The bottom of the frame will be held out by the bottombar, c, to which increased thickness may be given, as explained, or it may be held by the aid of the outwardly-inclined face of the sill A', which, with the added weight of the sash when the screen-frame is in place, will serve to hold it pressed out at the bottom without the aid of theincreased thickness ofthe lowerframebar referred to.

Short blocks may be used at the ends of the upper bar, c3, instead of the continuous strip d, and similar blocks may be applied at the ends of the lower bar, instead of making it thicker throughout its entire length, with the same result.

By the construction described the screen is made to snugly iill the opening made by raising the sash, and this without the aid of adjustable parts or pieces, thereby greatly sim- IOO plifying the construction and reducingthe cost thereof, While at the same time fully accomplishing all that the screen-frame is designed to accomplish.

The screen itself maybe made of an y usual or preferred material, applied to the frame in any convenient or preferred manner.

Having now described our' improvements, We claim 1. A Window-screen frame adapted, without the aid of adjustable part or parts, to pass within the sash groove or channel, in combination with the projecting spacing strip or flange for causing' it to overlap evenly the guiding strips or stops on the opposite sides of the windowframe, and for holding it snugly against said strips, substantially as described.

2. The screen-frame provided with the projecting strip or flange d, and with the sill or lower framebar, c, et' greater thickness than the side and top liars, substantially as and for the purpose described.
