' Filed March 21, 1928 Patented F eb. 24, 1931 FRANK L. MICHAELS, OE COVINGTON, KENTUCKY METAL WINDOW AND WEATHER STRIP Application filed March 21, 1928. Serial No. 263,248.

My invention relates to improvements in met-a1 window frame sash and Weatherstrip. One of its objects is to provide an improved combination of metal window frame sash and 5 Weatherstrip. Another object is to provide an improved arrangement of frame sash and. Weatherstrip in which the wind pressure from without tends to more tightly close the Weatherstrip joints to eifectively exclude wind and water. Another object is to provide and adapt improved weatherstrips to metal window frames and sashes produced from mitered sections of stock bars of extruded metal of specially provided cross-sectional design. My invention also comprises certain details of form and arrangement and combination of components, all of which will be fully set forth in the description of th accompanying drawings, in which:

Fig. 1 is an inside elevation of a wlndow frame and sash embodying my improvements.

Fig. 2 is an enlarged vertical section taken on line 22 of Fig. 1.

Fig. 3 is an enlarged sectional vlew'taken on the line 3-3 of Fig. 2.

The accompanying drawings illustrate one embodiment of my invention in which 15 represents the cap, 16- and 17 the side rails, and 18 the sill or ledge of a window frame, said frame being constructed from extruded metal, by cutting long bars thereof of especially designed cross-section into sections of the desired length and uniting said bar sections by brazing or similar means into a window frame. Guideways or channels 19 and 20 are provided along theinside of the side rails 16 and 17 to guide the vertical movements of the respective sash members 22 and 23. A vertical channel 24 in each of the side rails 16 and 17 provides a seat into rwhich the base of a detachable vertical parting strip or guide strip 25 together with a thin flexible strip of sheet metal Weatherstrip 26 enter and are held in place by means of a series of screws 27, which are threaded into perforations in the side rails 16 and 17. The upper sash is guided in its vertical movements between the ledges 28 of the siderails 16 and 17 and the guide strips 25 attached to said side rails 16 and 17.

The vertical window bead or guide strips 30 and flexible sheet metal weatherstrips 31 are held detachably in place relative to the side rails 16 and 17 to form channels 20 between the guide strips 25 and 30 by means of a series of screws 32 threaded into perforations in the side rails 16 and 17 The sash 23 moves vertically in the guideways 20 relaco tive to the window frame. The window frame is adapted to he set in brick or stone masonry or tobe set in a wooden framework as may be desired. Across the inside of the cap section 15 of the window frame is a chano5 nel 33 in which is detachably seated a cross bar 34, of cross section similar to that of the guide strips 25, and a flexible sheet metal Weatherstrip 35. The top edge of the upper sash when in closed position enters between a ledge 36 on the cap section 15 of the win-' dow frame, and the cross bar 34 and weatherstrip 35, as shown in Fig. 2. The cross bar 34 is detachably held in place by means of a series of screws 36. The upper sash 22 is built up from short mitered sections of extruded metal cut from stock bars of metal of especially designed cross sectional pattern substantially as shown. A glass panel 37 is mounted in the upper sash 22, and held in place therein by means of strips 38, detachably held in place by screws 39 or similar means. The cross sectional pattern of the lower cross bar of the upper sash at 40 is somewhat different from the cross sectional pattern of the top and side sections of the sash 22, in order to provide for making a weather proof joint between the lower edge of the upper sash and the upper edge of the lower sash. The 0 ening across the bottom of the lower cross ar of the upper sash is closed by means of an extruded metal strip 41, which is adapted to be inserted endwise or telescopically into place and to interlock with the edges of said lower cross bar substantially as shown in Fig. 2.

The lower sash is constructed from short mitered sections of an extruded metal bar of substantially the same cross sectional pattern, and substantially as described for the to make a wind and water proof joint be-' tween the two sashes where they meet. Any wind pressure upon this Weatherstrip 43 from outside of the sashes tends to hold the weatherstrip 43 more firmly in engagement with the lower portion of the upper sash. The

' strip 42 may be detachably locked to the ledge 44 by means of screws 45.

lVhere the lower cross bar of the lower sash comes in contact with the sill 18 of the window frame 18, a flexible sheet metal Weatherstrip 47 is detachably held in place between the sill 18 and the strip 48, and may be. detachably held in place by means of screws 49. The free edge of the strip 47 bears resiliently against the face of the lower cross bar of sash 23 substantially as shown in Fig. 2. Any wind pressure from without is adapted to act upon the strip 47 to press it more firmly against the lower cross rail of sash 23. The weatherstrips 26, 31 and 35 are also so arranged that any wind pressure from the exterior exerts a pressure upon the rear face of said strips so as to tend to close the Weatherstrip joint more eflectively. A glass panel 50 is held in place relative to the lower sash by means of detachable metal strips 51 secured in place by means of screws 52.

The apparatus herein shown and described is capable of considerable modification within the scope of the claims without departing from the spirit of my invention.
