METAL WINDOW-SASH.

Patented Aug. 11, 1914.

i and PERCY L. BART-ER, citizens of the United States, residing at Detroit, in the county of -Wa-yne and State of Michigan, have invented certain new and useful Improvements in Metal Window-Sash; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to, make and use the same. 7

Our invention has for its object to provide an extremely simple and highly eflicient 'metaljwindow'sash, especially designed for use in car construction, wherein combined strength and simplicity in the corner, or miter, construction is very essential.

To the above end, generally stated, the invention consists of the HOW-51 construction and arrangement of parts hereinafter described and' defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the everal views.

Referring to the drawings :Figure 1 is a side elevation of the improved window sash, some parts broken away, and some of the exposed parts shown in section. Fig. 2 1s an, oblique section taken on the line m m of Fig. 1, on an enlarged scale. Fig. 3 is a detail view, principally in section, taken on the line 00 m of scale; and Fig. 4 is a detail view in section, showing the rail sections separated at one ofthe joints.

1 The numeral -1 indicates, as an entirety, a metal window sash having its rail 2 made up of'v'ertical and horizontal flattened tubular sections, in rectangular arrangement, and connected by miter joints of novel construction which will presently be described. Each rail section 2 is primarily open at its outer edge andis constructed from a-single piece of sheet metal which is first blanked and then bent to shape. At their inner edges, the rail sections 2 are bent to afford a seat 2 for a glass panel and a seat 2 for the glass panel securing means. Forthe purpose of this case, it is not thought necessary to illustrate either the glass panel or its securing means.

At their ends, the sides of the rail sections 2 are bent laterally inward to afford, at each end of the rail sections 2, a pair of over- Flg. 1, on an enlargedi lapped flanges 3 that are spaced apart, one from the other, a distance equal to the thickness, of the metal from which they are formed, 'as best shown in Fig. 4. In assembling the rail of the window sash, the abutting ends of the vertical and horizontal sections thereof are connected by interlapping the flanges 3, as best shown in Fig. 3. This is done by bringing directly together all of the flanges 3 on the same side of the rail and overlapping the flanges on one side of the rail with the flanges on the other side thereof.

At each miter. joint, the interlapped sectionsz2, at their miter joints, against twisting action.

After the rail sections 2 are securely joined together, the open outer edges thereof are permanently closed by a shoe 6. This shoe 6 is preferably made channel shape in cross section,as shown, withitstransverse portion? spanning "the-"opening between the sides of the rail sections 2, and with its side flanges embracing the outer longitudinal edges of the sides of the rail sections 2. The shoe 6 is preferably secured to the rail sections 2 by sweating, and may be constructed either-from asingle piece of metal bent rectangular, to fit around the rail sec tions 2, or in a separate section for each rail section 2.

What w claim is 1. A metal window sash having a tubular rail, the sides-of said rail being bent'laterally inward, at their ends, to aflord overlapping, laterally spaced flanges, the flanges on the same side of said rail being brought directly together, the flanges on the one side being overlapped with the flanges on the other side, and means securing the same to- 'gether.

2.. A metal window sash having a tubular rail, the sides of said rail being bent laterally inward, at their ends, to afford overlapping, laterally spaced flanges, the flanges on the same side of said rail being brought directly together, the flanges on the one side being overlapped with the flanges on' the other side, and means securing the same together, comprising clamping bars and bolts.

3. A metal window sash having tubular rail sections in rectangular arrangement, the sides of said rail sections being bent laterally inward, at their ends, to afford overlapping, laterally s aced flanges, the flanges on the same sideo said rail sections being T. Y. J OSLYN, J. W. CAIN.
