WEATHER-STRIP FOR SHEET-METAL WINDOW-SCREENS.

Specification of Letters Patent.

Patented Oct. 2, 191 7.

Application filed March 26, 1917. Serial No. 157,360.

To all whom it may concern:

Be it known that I,W1LLIAM W. WA'rsoN, a citizen of the United States, residing at the city ofJamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in feather-Strips for Sheet-Metal \Vindow-Screens, of which the following, taken in connection with the accompanying drawings, is a specification.

The invention relates for window screens having sheet metal frames and is an improvement upon the screen construction shown in'Let/ters Patent Nos. 836,47 5 and 956,239; and the object of the improvement is to provide a tubular screen frame having a lengthwise attaching groove on its inner edge for the screen fabric and a lengthwise attaching groove on the outer edges of the top and bottom rails for weather strips; and the invention consists in the novel features and combinations hereinafter set forth and claimed.

In the drawings, Figure 1 is a plan view of the upper and lower corners of the screen frame without the screen fabric attached thereto showing the groove for the weather strip on the upper edge and the weather strip on the lower edge. ig. 2 is a sectional perspective view of a portion of one of the sides ofthe window screen at line X-X in Fig. l-showing the screen fabric attached in the groove on the inner edge and a weather strip in the groovein the outer edge and extending sidewise; and Fig. 3 is a sectional and perspective view at line Y-Y in Fig. 1 of the lower side of the screen frame showing a lengthwise groove for a weather strip so placed that said weather strip extends in line with the screen frame and can be pressed against the window sill or other support, and Fig. at is a similar view of the opposite side of said screen side. Fig. 5 is a perspective view of the preferred form of the weather stripping.

Like characters of reference refer to corresponding parts in the several views.

The numeral 10 designates the tubular sheet metal frame side which is cut and bent from the flat sheet metal strip by means of suitable dies and pressed so as to form the lengthwise groove 11 along the inner edges of the frame sides.

The numeral 12 designates one of the sides, usually the top rail, which is preferably formed of one or more strips of sheet to weather strips metal shaped to form a. lengthwise groove 11 opening sidewise along the inner edge and a lengthwise groove 13 opening sidewlse along the outer edge, both of said grooves enlarging inwardly. The inner groove 11 enlarges inwardly to receive the spline or strip 14: to hold the screen fabric 15 within the groove 11. The outer groove 13 enlarges inwardly to receive therein the metal bound weather stripping 16; which weather stripping is preferably made of a folded strip 17 of rubber or similar flexible material havin the edges held by a U shaped metal biming strip 18 which fits within and is slidable endwise or may be sprun mto the groove 13, the turned edge 21 holding said weather strip 16 firmly in place within the groove 13.

The upper frame side 12 is preferably formed of the two sheet metal strips 19 and 20, the two lengthwise contacting edge portions of which are pressed together and -bent into the lengthwise channel groove form along each of the edges, both edges of the sheet 20 being left short and both edges of the sheet 19 on the outer side extendin over the edges of the sheet 20 into each 0 the grooves 11 and 13 thereby narv rowing the mouths of each of the grooves 11 and 13 the thickness of the sheet metal, which arrangement, taken with the inwardly enlarging opposite side, so forms said grooves that they may be described as enlarging inwardly,the inwardly turned edge 21 of each of the grooves forming the locking member which holds the spline or strip 14; in the groove 11, and the sheet metal folded strip 18 the weather stripping 16 in the groove 1 I The contacting surfaces of the edges of the plates 19 and 20 are joined together and may or may not be soldered or welded to one another so that the central tubular portion becomes a closed tube with interlocked welded, soldered, or otherwise attached edges on opposite sides.

The lower tubular frame side 22 is preferably composed of two sheet metal strips 23 and 24 in somewhat the same form as the frame side 12, the exceptions being that the groove 11 is sometimes made slightly different, the strip 23 being bent at an inclined angle 25 to prevent the use of sharp hooked instruments upon the screen or erably formed on the outer side of the rail 22 and opens downward so that said weather strip 16 may be pressed downward onto the window sill.

In order to form the lengthwise groove 26 a shoulder 27 is bent in the strip 23 of the desired width for the groove 26. The groove 26 is formed largely in the sheet metal strip 24c and the edge 21 overlaps the edge of the groove side 24, the same as in grooves 11 and '13 thereby narrowing the mouth of the groove 26 so as to retain the folded metal binding strip 18 of the weather strip 16 within the groove 26, the same as in groove 13. The contacting surfaces of the strips 23 and 24 may be soldered together or otherwise attached so as to render the frame side 22 as rigid as possible and thereby give the required stiffness to the entire screen frame.

The corners of the screen frame are preferably mitered and united by means of sweating, bolting, screwing, soldering, welding, or any suitable method. The inner corners are braced by extending the folded inner edges so as to interlap upon one another, as shown at 28, the groove side being bent to one side as shown at 29 sufficiently to receive the folded end of the adjacent frame side and the lapped ends are soldered, welded or otherwise fastened together so as to firmly hold the same. In the beveled inner edge 25 of the lower rail the folded end 28 is lapped within said edge 25 within the groove 11 and fastened thereto thereby strengthening the lower corners.

I claim as new 1. In a window screen,a sheet metal frame having a groove, a folded strip of resilient material, and a strip of sheet metal folded over the edges of said. folded strip to bind the same and received in the frame groove.

2. Inawindow screen,a sheet metal frame having a. groove, a strip of resilient material, and a strip of sheet metal folded over the edges of said folded strip to bind the same, said frame having an inturned sheet metal edge extending into the groove thereof to interlock with the edge of said folded strip of sheet metal.

3. In a sheet metal window or screen, the combination of the frame with a groove meme? projection to lock the casing in the groove.

5. In a sheet metal window or screen, a

frame having a' groove, a flexible strip, a

casing composed of a strip folded over said flexible strip for holding same, and means carried by the casing to automatically lock the casing in the groove by engagement with an edge of said folded strip and upon movement of the easing into the groove. v

6. In a sheet metal window or screen, a frame having a groove, a flexible strip, a casing for holding said strip, and means in the groove to lock the casing, a wall of said groove being capable of flexure to allow said casing to spring over the locking means.

7. In a sheet metal window or screen, a frame formed of a member shaped to form two grooves and a second member connected to the first member and having its opposite edges extending into the respective grooves, a flexible strip, and a casing for holding the strip received in one of the grooves and engaged with one of said edges to lock the casing therein.

8. In a window or screen, a tubular metal frame formed to have a groove and having an inturned edge of the metal extending into the groove, a flexible strip, and a holder of U-shape in cross-section receiving said strip, the free edge of one of the legs of the U-shaped holder being engaged with said inturned edge of the frame to lock the holder against movement out of the groove.

In testimony whereof I have afiixed my signature in the presence of two witnesses.

WILLIAM W. WATSON.
