Patented May 7, 1946 SASH STRUCTURE Peter iL Kuyper, Pella, Iowa, assignor to Rolscreen Company, Pella, Iowa, a corporation of Iowa . Application October 26, 1942, Serial No. 463,338

2 Claims.

My present invention relates to a sash structure which may be furnished by the factory and which obviates the necessity of a frame surrounding the sash.

One object of the invention is to provide a sash which can be manufactured at small expense, and which eliminates the usual framing for sashes and the attendant work necessary inplacing, assembling and aligning such framing, the present invention contemplating a unitary sash which can be mounted directly in an opening in a wall, regardless of the construction of the wall, the sash being suitably mounted in such opening by the use of appropriate backing strips along the inner faces'thereof and calking around the edges thereof, or other suitable means to mount and seal the sash framerelative to the window opening."

In providing a sash of this character it is desirable to have a ventilating section in the sash, This raises the problem of the horizontal and vertical frame members of the sash'being necessarily a different cross-section at the ventilating section than where a stationar pane of glass is glazed into the sash opening. It is therefore a further object of my invention to provide a sash formed of horizontal and vertical frame'elements so designed that they can accommodate either a ventilating section or a stationary pane of glass, the cross-sectional shape specifically being designed to accommodate the ventilating section, and fill-in or adapter strips being provided where there is no ventilating section. These strips fit the rabbets provided for the ventilating section and alter them for glazing of the stationary .panes with relation thereto.

Still another object is to provide, in combination with a sash having oppositely rabbeted frame elements to accommodate a ventilating section, fill in strips of Z and L-shape which adapt any particular opening of the sash for a stationary pane of-glass rather than a ventilating section.

In general, it is my object to reduce the number of cross-sectional shapes necessary in building up sashes of the kind herein disclosed. by making certain frame elements of such shape as to accommodate ventilating sections and then using fill-in or adapter strips to change the crosssection for adapting them to a pane of glass glazed in position, and thus stationary with relation to the sash frame.

With these and other objects in View, my invention consists in the construction, arrangement and combination of the various parts of my device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawing, wherein:

Figure 1 is an outside elevation somewhat diagrammatically showing a sash structure embodyin my invention;

Figure 2 is an enlarged vertical sectional view on the line 2-2 of Figure 1, this section being taken through a hinged ventilating sash element;

Figure 3 is a similar sectional view on the line 3-3 of Figure 1 taken through two stationary panes of glass in the sash and showing the fill-in or adapter strips for the sash used in Figure 2;

Figure 4 is a sectional view similar to Figure 2, showing the sash hinging inward instead of outward, and the glazing inside. (In Figures 2, 3 and 4 the glazing is also inside) Figure 5 shows a similar sectional view with the sash hinged inward and the glazing outside;

Figure 6 is a similar sectional view showing the fill-in or adapter strips'for Figure 5; and

Figures 7 and 8 are perspective views of two representative adapter strips which can be used in my sash structure.

0n the accompanying drawing, Figure 1 shows a complete sash which includes horizontal and vertical frame members, stationary panes of glass and'a ventilating section or sash. The horizontal members consist of lower and upper rails l0 and I2 and a horizontal mullion 14, whereas the vertical members comprise a pair of stiles I6 and two pairs of mullions l8 and 20. The various frameelements 10 to 20 may be broadly termed sash frame elements or horizontal and vertical sash frame elements, the importance of which will be evident when considering the claims of this patent. r

In Figure 1 I have shown five stationary panes of glass 22 and a pane of glass 24 forming part of a ventilating section. The ventilating section 24 has stiles 26 and lower and upper rails 28 and 30.

Referring to Figure 2, the rail l2 along its lower edge and the upper edge of the horizontal mullion M are suitably'rabbeted to receive the stationary pane of glass 22 puttied into position, as at '32. The lower edge of the horizontal mullion I4 is rabbetted, as at 34, the rabbet being in the inner face of the mullion, and the lower rail I0 is rabbetted in its outer face, a at 36. The opposite rabbets 34 and 36 fit companion rabbeted edges 38 and 40 of the lower and upper frame elements 28 and 30 of the ventilating section. The arrangement shown in Figure 2 is 22, the glass will not fit into the rabbets 34 and 36. Accordingly, I make provision for the fitting of the glass 22 therein by the use of a Z- shaped adapter strip 44 in the rabbet 34 and an L-shaped adapter strip 46 in the rabbet 36, as shown in Figure 3. The strip 44, it will be noted, has three surfaces 48, 5|] and 52 designed to fit closely against the mullion 14, wherea the strip 46 has two surfaces 54 and 56 closely fitting in the rabbet 36 of the rail 10. The strips may be glued in position, and are each provided with rabbets 58 and 60 respectively, aligned with the rabbets for the upper stationary pane of glass 22. Thus the lower stationary pane of glass may be inserted and puttied in position, as shown at 62, when a stationary pane instead of a ventilating section is desirable in a window opening formed by the horizontal and vertical frame elements of the sash.

The cross-sectional shapes of the horizontal elements l and I4 may be somewhat modified, as shown in Figure 4, and, likewise, the rails 28 and 30 of the ventilating section may be modified to interfit therewith when the ventilating section is to be hinged-for inner Swinging movement instead of outer swinging movement. It is believed obvious how fill-in strips may be then provided where the stationary panes of glass 22 are located in a manner similar to Figure 3, although these fill-in strips may-differ slightly in cross-section, as shown in Figure 6, for instance.

Figure 5 again shows inward hinging, but outside rather than inside glazing, the various sash frame elements being modified in cross-section to accommodate the panes-22 and 24 for outside glazing rather than inside glazing.

Figure 6 illustrates how the arrangement of Figure 4 or Figure 5 isprovided"'with fill-in strips, one of which, 44, is identical with the fillin strip 44 shown in Figure 3. The other one, 46 however, has been modified slightly in crosssection to accommodate outside rather than inside glazing, but accomplishes the same purpose, in that it converts an opening originally designed for a ventilating section to an opening which is designed to receive a stationary glass pane. Thus I am able to use the p op frame elements and the proper fill-in strips to secure any variation of the sash structure for either inside or outside glazing and ventilating sections which move either inwardly or outwardly. It is also believed obvious how a ventilating section having a plurality of panes of glass may be inserted in a larger sash having stationary panes of glass all around it. In each instance the fillin strips are used wherever a stationary pane of glass is in horizontal alignment with a pane of glass in a ventilating section, and where such stationary pane of glass is adjacent the rail or mullion along the bottom or top of the ventilating section. As to the vertical mullions 20, they, of course, may be shaped on one side to fit the sash and on the opposite side to fit the stationary pane of glass without any unusual problem being presented, as they are not continuations of the mullions l8.

From the foregoing description it will be obvious that I have designed sash frame elements which may be fabricated to form a sash frame, and will, wherever desired, accommodat a ventilating section. Wherever the cross-sectional shapes of the frame element are improper for a stationary pane of glass, the mere addition of afill-in or adapter strip at this point takes care of the problem very nicely, and does so with a minimum of special machining on the frame elements. The frame elements may thereby all be provided of uniform cross-section throughout their lengths, and short sections of fill-in strips placed in position wherever necessary.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalent which may be reasonably included within their scope without sacrificing any of the advantages thereof.

I claim as my invention:

1. A sash structure comprising horizontal frame elements arranged spaced from each other and extending from side to side of the sash tructure, vertical frame elements spanning said horizontal frame elements whereby openings are defined thereby, a ventilating section in one of said openings, stationary panes of glass in the other openings, those of said horizontal frame elements occurring at the top and bottom of said ventilating section being uniform in section throughout their lengths to directly interfit with the upper and lower edges of said ventilating section,'and fillin strips for said horizontal frame elements and extending only between said vertical frame elementsat'the edges of said stationary panes of glass, said fill-in strips fitting said last mentioned horizontal frame elements and being shaped toreceive the adjacent edges of said panes of glass. 1

2. In a sash, structure of the character disclosed, horizontal frame elements arranged in spaced relation to each other, vertical frame element between said horizontal frame elements and spaced from each other whereby openings are defined by the horizontal and vertical frame elements, a ventilating section in one of said openings, the horizontal frame elements adjacent the top and bottom thereof being one inwardly and the other outwardly rabbeted, said ventilating section interfitting directly therewith to provide a weather seal joint, a stationary pane of glass in each of the other openings, a Z-shaped adapter strip in one of said rabbets and an L- shaped adapter strip in the other of said rabbets whereby the rabbets are filled, and the crosssectional shape of said horizontal frame elements adjacent said panes of glass are changed by said strips to receive the'edges of the panes of glass.
