To wZZ whom it may concern:

Be it known that we, GEORGE H. S'ron'r and Lucius A. TURNER, citizens of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Window-Screens, of which the following is a specification.

Our invention relates to window-screens in which the screen fabric is held to close the W111 the side edges of the fabric bearing against the outer faces of the blind-stop and its top and bottom bars secured at their end edges to the opposing faces of the blind-stops. Fig. 2 is a vertical section of the same. Fig. 3 is a perspective view of the inside of our improved screen constructed to screen either the whole or the half of the window -opening whether the contact of the side edges of the I fabric be upon the outer faces of the blind- 5 View of Fig. 5, broken away at one corner to stop or brick-mold and showing our new takeup levers withdrawn from their fulcrum-sockets. Fig. 4 is a bottom view of Fig. 3 on line 0 d and showing the screen as applied to the frame, (shown as in Fig. 1,) but showing a thin metallic molding for securing the wire fabric to the outside of the top and bottom bars. Fig. 5 is an inside view of the window frame and opening, showing our improved screen as secured at its top to the opposing faces of the brick-mold and a modification of the means of securing the top edge of the top rail from lat eral, tipping and also showing the take-up levers inserted in their fulcrum-sockets and acting to hold the screen fabric taut and against the outer face of the brick-mold. Fig. 6 is a partial view of the same, showing the take-up levers withdrawn and held in such position by their hearing betweentheir retaining hooks and eyes. Fig. 7 is a vertical section of Fig. 5 on the line a Z). Fig. 8 is an outside or front stops to prevent lateral pull the screen fabric taut.

show the engagement of the take-up lever with its fulcrum-socket and its guide-slot in the end of the bottom bar of the screen. Fig. 9 is a partial view similar to Fig. 8, showing thetop bar constructed for application to a window-frame having. a segment-head and especially showing the function of the telescopetipping of the screen top bar.

The screen 1 is preferably of wire fabric and at its top is secured to the outside side edge of a top bar 2, having in either end a slot 3. I

The bottom edge of the screen fabric is secured to the outside side edge of a bottom or sill bar 4, provided at its end edges with slots 5 and on the top of said bar and near its ends with screw-eyes 6 and hooks 7 and take-up-lever bars 8. I Our new screen is designed to be attached to the window-frame at its top by hanging its top bar 2 by means of its end slots 3'on the studs 9, which are preferably in the form of screw-eyes and driven into the'opposing side faces of the window-frame whether these studs extend inwardly from the opposing side faces of the brick-mold 10 or blindstop 11.

Its connection at its bottom is bymeansof inserting .the ends 12 of the take-up levers 8 into fulcrum-sockets 13, let into the opposing side faces of the blind-stop or brick-mold of the window-frame.

side faces of either the brick-mold 'orblindstop of the window-frame and perfectly close when freed of the hooks 7 and inserted into.

their fulcrum-sockets 13 and pressed downward at their free ends bear down on the two ends of the top edges of the lower bar 4 and The free ends of the take-up levers are then hooked under the hooks 7 to maintain the downward pressure on the screen, and as the hooks? are out near When :the top bar 2 is rigidly secured at the top of the window-opening in the manner described and the bottom bar 4 is pulled downward, the side edges of the screen fabric will fit tightly against the outthe free ends of the take-up levers there is a yielding throughout the length of the take-u p levers and a consequential yielding on the screen fabric in case such fabric be subjected to undue strain.

Since the top edge of the top bar must parallel the under face of the head of the windowframe, it is desirable that the top bar of the screen have little or no vertical play, and with this object in view We preferably provide the end opening slot 3 in the bars 2 with inside side-opening entrances 14, adapted to receive the studs 9 upon positioning the top bar with its top edge meeting and parallel with the under face of the frame-head and with the side entrances 14 to said slots 3 opposite said studs 9 and then pulling inward on said top bar until the studs 9 meet the farther inside side walls of the vertical slots 3 and then dropping said bars until the studs 9 bear against the roof of the slots 3, at which position the top bar of the screen is stationary with respect to the frame by reason of the fact that its inner sides bear against the outer vertical faces of the window-frame, blind-stops, or brick-molds, as the case may be.

The end slots 3 are conveniently constructed by first boring into the very end edges of the side wall of the top bar for a distance reaching the farther vertical wall of the vertical slot, which is obtained by chiseling from the end of the bar for a slight distance above the roof of the side bore and then chiseling for the entrance of the stud sidewise to the vertical slot 3 from the inside of the bar for only such a distance above the bottom of the vertical slot as to allow the side entrance therein of the studs 9.

In the case of window-frames having a segmental head it is obvious that the bearing of the inner vertical walls of the slots 3 would be insufficient to prevent the outward tipping of the top bar, and to provide against this telescope-stops 15 of well-known construction are provided in said top bars so as to project upwardly from the top edge thereof into sockets 16, let into the under face of the frame head, as shown in Figs. 9, 8, 7, and 5. In Figs. 5, 7, and 8 the telescope-stops are shown as applied to a window-frame the under face of the head of which is horizontal, and though the function of said telescope-stops is the same as with a segment-headed frame their application in these figures is especially shown to illustrate the function of'said telescope-stops to prevent any outward tipping of the top bar when used on these windowframes,which, by reason of their varied construction, necessi tate the use of a wide top bar.

Over the screen-fabric fastenings on the outer sides of the top bars is a stripof molding 17, extending above the top edge of the top bars for sufficient distance to provide for the drop of the same on its studs and beyond each edge of the same to the edge of the screen fabric. This molding 17 also on the bottom bar may be constructed of thin metal, so that when the screen is applied to a window-frame having outside shutters it will not interfere with the closing of said shutters or blinds against the blind-stop, as there is usually a slight play on the hinges of the shutters. When used with shutters, the screen is hung to the opposing faces of the blind-stop, as shown in Fig. 4. When the window-frames are not provided with shutters, the screen is preferably hung to studs projecting from the opposing faces of the brick-mold, as shown in Figs. 5, 6, 7, 8, and 9, and in such a case the molding 17 is preferably of wood and may be of any thickness. I

When the topbar of the screen is positioned as shown in Figs. 5, 7, and 8, the mold 17 will extend above the top edge of the top bars and close the opening between the under face of sets; but it is desirable that those insects which 1 enter the house at other points have means of exit, and for this purpose an opening 18 is provided in thetop bar 2. This opening is preferably made by sawing out a slot from the under face of the top bar upward and partially cutting themeeting face of the mold 17, and such opening is preferably flared in both directions at the bottom, so as to give therethrough ready exit to the common fly, the well-known tendency of which is to crawl upward and of which, as is well known, it is disinclined to crawl downward through an opening, so that such an opening 18 is in a sense a fly-trap, since it affords ready exit for flies upon the inside of the screen, but baflies their entrance.

For the reason that the screen fabric may stretch during thefrepeated pressure thereon of the take-up levers to such a degree as to allow the bottom of the bottom bar no further movement to stretch the screen taut against the outer faces of brick-mold or blind-stop the eyed bearings 6 are seated in the top edge of the bottom bar, so as to have adjustment vertically. In the drawings this adjustment is shown to be obtained by sci'ew threads upon the stem of the eyes. Such an adjustment is also desirable in case the commercial screen fabric do not accommodate the calculations for its stretch to the calculations of the adjustment of the bearings of the take-up lever on the bottom bar or the fulcrum-socket bearings in the inner faces of the opposing sides of the window-frame. The hooks 7 are like wise adjustable.

We claim a l. A screen for windows consisting of a sheet of screen fabric spanning the window-opening and having top and bottom horizontal framebars, of means for securing said top bar in rigid parallel relation to the under face of the head. of the window-frame, and means for maintaining the inner surface of the screen fabric at its side edges closely against the outer vertical faces of the window-frame consisting of take-up levers at both ends of said bottom bar having end fulcrum-bearings in the opposing faces of the window-frame and hearings on said bottom bar near its ends, hooks on said bottom bar between its end take-up-lever bearings adapted to retain the depressed free ends of said take-up-lever bars, for the purpose and in the manner substantially as described.

2. In a detachable Window-screen having only horizontal top and bottom frame-bars the top bar of which is fixed to studs projecting from the inner faces of the window-frame and the bottom bar of which is held down toward the sill of the window-frame by take-up levers having a fulcrum-socket bearing in the inner faces of the Window-frame, avertically-adjustable eyed bearing for said take-up levers located on top of and near the ends of said bottom bar, hooks on top of said bottom bar retaining the depressed free ends of said takeup levers passing through vertical slots in the ends of said bottom bars, substantially as described.

3. In a window-screenof the class described, means for securing its top bar in fixed parallel relation to the under face of the windowframe head, means for holding the outer ver tical edges of the screen fabric close against whereby to engage and retain the free ends of said take-up levers, substantially as described.

4. A screen for windows consisting of a sheet of fabric closing the window-opening and contacting with the outer faces of the brick-mold or blind-stop and having top and bottom horizontal frame-bars, slots in the ends of said top bar, stud-openings into said slots on the inner side of said top bar adapted to receive studs projecting from the opposing faces of the windo Wframe and means for downwardly pulling said screen fabric adjustably against its fixed top-retaining means, substantially asand for the purpose described.

In testimony whereof we afiix our signatures in presence of two witnesses.
