WINDOW-SASH.

Specification of Letters Patent.

Patented Jan. 10, 1911.

Application filed May 27, 1910. Serial No. 563,764.

To all whom it may concern:

Be it known that I, FRANK citizen of the United States, Salem, in the county of Marion and State of Oregon, have invented certain new and useful Improvements in Window-Sash; and I 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.

lWIy invention relates to window sashes and particularly to the construction of the connection or joints between the sash bars or mullions.

My object is to simplify the construction of these joints whereby less time will be required to make window sashes and the cost of manufacture thereof will be reduced.

Other objects will become apparent from the following description.

It is my aim to obviate mortising and tenoning the bars or mullions of the sash as is now usually done. I propose to connect these bars by simply boring one or more holes in the molding of the horizontal bars to fit the ends of the sections of the vertical bars which are cut off square. These holes are only bored down to the surface of the bar proper, that is to the base of the molding, so that it is not necessary to form tenons on the ends of the bars which fit in said holes. The moldings on said bars are made either round or oval in cross section in order that the ends of the vertical bars will fit into the holes bored in the horizontal bars. Because of the rounded form of the molding and the holes or sockets into which they fit, my new connection retains the bars from moving eitlier way, that is vertically or horizontally, just as effectively as the old mortise and tenon joints.

The invention also consists in the features of construction and combinations of parts hereinafter described and specified in the claims.

In the accompanying drawing: Figure 1 is an elevation of a portion of a window frame constructed in accordance with my invention. Fig. 2 is a sectional view on the line w0c of Fig. 1. Fig. 3 is a sectional view on the line Q/--:I/ of Fig. 1. Fig. 4 is a detailed View of a portion of one of the horizontal sash bars. Fig. 5 is a similar View of one of the sections of the vertical sash bar, and Figs. 6 and 7 are similar views M. BnowN, a

residing at of a horizontal bar and section of vertical bar of a modified construction.

Referring more particularly to Figs. 1 to 5, inclusive, of the drawing, 1 and 2 designate respectively one of the stiles and one of the rails of a sash which may be connected together in any suitable manner. Each of these pieces is provided with a rounded molding 3 having round holes 4: bored therein at suitable intervals to receive the ends of the bars or mullions. The horizontal bars or mullions 5 extend entirely across the sash while the vertical bars 6 are made in sections of suitable length to fit between the horizontal bars. It will be understood, of course, that this arrangement may be reversed and the horizontal bars made in sections and the vertical bars made continuous, if desired. The moldings 7 on said bars or mullions are also rounded. Round holes 8 are bored in the moldings of the horizontal bars to receive the ends of the sections of the vertical bars. It will be noted that these holes are of greater diameter than the molding so that openings 9 are left at either side thereof through which the ribs 10 and 11 project. It will be understood, of course, that said ribs 10 and 11 extend into the planes of the inner and outer faces of the sash respectively, the outer ribs 11 being longer than the inner ones in order to receive the panes of glass 12 and the putty 18 which secures the latter in place. The bars are rounded in cross section where the moldings are formed on the opposite sides thereof. As illustrated in Fig. 41, the holes bored to receive the ends of the bars are round and may be formed by one operation of a boring tool. If desired, however, the bars may be oval-shaped at the points where the moldings are formed and the holes to receive them may be correspondingly oval-shaped, as illustrated at 1 1 and 15 respectively in Figs. 6 and 7. These oval-shaped holes 15 may be readily formed by boring two or more round holes side by side. The oval-shaped sash bar is therefore suitable for any thickness of sash, the oval being lengthened or shortened as desired to conform to the thickness of the sash.

The simplicity of applicants connection or joint and the greatly reduced expense re quired to manufacture it. will be readily appreciated by those skilled in this art. No special machine is required for forming the parts of the joint, as is necessary in making ion the mortise and tenon joints. All that is needed in order to connect my sash bars is on ordinary brace and bit or other suitable boring tool for forming the holes in the molding to receive the squared off ends of the bars.

I am aware that the end of one sash bar has heretofore been grooved out to fit over the molding on another but it was then necessary t.o use a tenon on the end of the grooved bar fitting into a mortise in the other bar to secure the latter against longitudinal movement with respect to the former. My construction retains the bars against movement in either direction with out requiring a mortise or tenon and is, therefore, much cheaper to manufacture as well as simpler in construction.

I claim 1. In a window sash, the combination, with a bar having raised moldings on its faces and holes formed in said moldings extending to the bases thereof, respectively, said holes being broader at the interior of said moldings than at the edges thereof, of another bar arranged at right angles to the first bar and made in sections having squared off ends, the adjacent ends of said sections being fitted in the holes in the moldings of said first bar.

2. In a window sash, the combination, with a bar having rounded moldings on its faces, and rounded holes formed in said moldings extending to the bases thereof, respectively, of another bar arranged at right angles to the first bar and made in sections having squared off ends, the adjacent ends of said sections being fitted in the holes in the moldings of said first bar.

3. In a window sash, the combination, with a bar having raised moldings on its faces with projecting ribs extending in opposite directions, the said moldings having holes formed therein extending to the bases thereof and flush with said ribs of another bar of similar shape but made in sect-ions having their ends squared off, the adjacent ends of said sections being fitted in the holes in the moldings of the first bar with their ribs extending beyond said holes into the planes of the ribs on said first bar.

at. In a window sash, the combination, with a bar having rounded moldings on its faces with projecting ribs extending in opposite directions, the said moldings having holes formed therein extending to the bases thereof and flush with said ribs, of another bar of similar shape but made in sections having their ends squared ofi, the adjacent ends of said sections being fitted in the holes in the moldings of the first bar with their ribs extending beyond said holes into the planes of the ribs on said first bar.

5. In a window sash, the combination, with a bar having rounded moldings on its faces, and oval-shaped holes formed in said moldings extending to the bases thereof, respectively, of another bar arranged at right angles to the first bar and made in sections having squared off ends, the adjacent ends of said sections being fitted in the holes in the moldings of said first bar.

In testimony whereof, I affix my signature, in presence of two witnesses.
