2 Claims. (o1.20 56.1)
This invention relates to improvements in window sash, and more particularly to a window sash adapted to be glazed and to have broken panes replaced without the use of putty and like agents. so-called puttyless sash intended primarily for structures other than those used for human habitation, such as barns, tool sheds, and like buildings requiring a lighted interior but not the same weather-tight construction, However, with a slight additional sealing the sash herein disclosed may be quite satisfactory for house construction.
The object of the invention is to provide a window sash which will permit the fitting of the panes of glass without the services ofa skilled glazier, thus making it a simple and inexpensive matter to replace broken panes. Moreover, it is possible to ship and install a puttyless type of sash without glass, thereby reducing the expense of packaging against glass breakage and the increased cost of transportation incident thereto.
A preferred embodiment of the invention is in the accompanying drawing, in which: I
Figure 1 is a general view in elevation of a standard four-panel sash;
Figure 2 is an enlarged view in elevation of one corner sectionof the sash showing the details of construction;
Figure 3 is an enlarged view in vertical section through the sash as taken on line 3-3 of Figure 2;
Figure 4 is a view in elevation similar toFigure 2, but with portions removed to show the manner in which the margins are rabbeted to receive the panes of glass; 1
Figures 5, 6, and 7 are Views in horizontal section through the sash to illustrate the process of fitting the panes of glass into the sash;
Figures 8 and 9 are views in side elevation and top plan, respectively, of one of the pane-retaining springs; and
Figure 10 is an enlarged detail view in section as taken on line |BH] of Figure 4, showing the manner in which the panes are held in place by the springs and also disclosing a slight modification in the form, of a groove for a sealing compound, if desired.
The sash shown in Figure 1 is of standard mill construction consisting of top and bottom rails I, l and upright stiles 2, 2 enclosing a rectangular space which is divided into four sections by a pair of intersecting bars 3, 3. The construction and finish of the sash may vary according to grade, but the fashioning of the various mem- In short, the invention pertains'to a of the rails I, stiles 2 and bars 3, but instead of open rabbets into which the panes are set and then anchored and sealed with putty, the inner edges of one pair of opposed edges surrounding each pane-receiving opening are grooved to receive the corresponding edges of the pane and the other edges being provided with -L-shaped rabbets facing laterally and outwardly. Ordinarily the panes are installed from the outside of the sash, but except that one side is made more weatherproof thanthe other, the sash might otherwise be reversible.
Now referring to a single pane mounting, as in Figure 4, there is cut in the inner edge face of the outer upright frame member or stile 2, a relatively deep groove 5, just wide enough to receive the edge of a panel of glass 4 of standard thickness with a minimum of clearance. At the top and bottom of the opening theedges of the cross bar 3 and bottom rail l are cut back to form the L-shaped seats 6, 6 facing outwardly and forming shoulders lying in the plane of the innermost side walls of the groove 5. The rabbets 6, 6 are relatively shallow measured in the direction of the plane of the glass panel, their purpose being to support the upper and lower edges. of the pane and to hold it against vertical movement. Andlastly, along the inner side of the opening and cut in the edge of the vertical bar 3 is a groove or rabbet 1 slightly shallower than the groove 5 in the opposite edge of the rail 2. In this manner the inner edges of the openings into which glass is to be fitted are either larger in both dimensions than the opening, but
having its width or narrower dimension slightly less than the distance between the bottoms of the :inwardly facing grooves -5 and 1 along opposite sides.
Now, mounted within the deeper groove 5 is a pair :of resilient pane-retaining members in the form of flat leaf springs 8 bent into the shape of a bow, .as clearly shown in Figure 8. The springs are made from strips of thin spring steel and at one end of each is fashioned a pair of prongs 8 8, preferably projecting laterally from opposite edges. Two, and if necessary more, of these springs are fitted into the deeper groove 5 in spaced relation and secured in place by twisting their pronged ends so that they grip the sides of the groove, leaving the opposite end free to slide on the bottom as the spring is flattened. The central portion of each spring lies just below the entrance to the groove and, for a reason that will presently be seen, the edge of each spring is preferably upset slightly at its central or high point as at 8 so as to provide a beveled or camlike surface.
Assuming, then, that the pane 4 is properly sized to fit the opening, it is applied from the outside of the sash by first presenting one of its longer side edges to the deeper springequipped groove 5, as shown in Figure 5. The" pane is then forced endwise intothe grooveifar enough to depress the retaining springs and allow its other edge to be brought into align ment with the shallow rabbet 1 on the opposite side of the opening, as shown in Figure 6,
--sides of the glass panes, as desired.
the regular manner, these auxiliary rabbets whereupon the pane is released so thatthe ten-' sion of the springs now acts to force it edgewise and into the shallow rabbet l, as shown in Fig .ure 7.
In the operation of installing the pane, its top and bottom edges simply seat flush into the channels 6, 6, as shown in Figure 3, it being obviously desirable for the glass to be dimensioned to fit as snugly as possible and with little or no clearance at the top and bottom.
Thus each pane, as it is installed, is held in place by the springs 8, which yieldingly force them sidewise and against the bottom of the shallow rabbets l which may, if desired, have tapered rather than straight sides to insurie a tighter fit of the glass.
In addition, the beveled portions 8 of the springs are preferably located so that they tend to force the panes laterally against the inner faces of the grooves 5 and 1 and the recessed seats 6, 6 at the top and bottom. In this manner the panes are held with greater firmness and with less tendency to rattle or leak.
In order to make the sash as weatherproof as possible, the outer face thereof is treated in the following manner: The upper edge of each rail or cross bar, as the case may be, is grooved on the under side as at 9 (Figure 3) just outwardly from the top edge of the pane of glass 4, so as, to collect the water, and cause it to drip rather than to seep between the edge of the glass and the sash. Similarly, thelower edge of each cross bar or rail is beveled outwardly from the bottom edge of the panev 'as at Ill (Figure 3) so that the water will be carried off and not accumulate along the edge of the glass.
It will be understood that certain variations and modifications may be resorted to without departing from the spirit of the invention. For example, different styles of springs may be used for retaining the glass in place and particularly in the manner in which the springs are installed and anchored. Again, it may be desirable to form the grooves somewhat wider at the bottom than at the top. This would permit the use of a slightly heavier spririgif needed, although it necessitates its installation from the ends of the groove.
Another modification which is disclosed in would be filled with some mastic substance or sealing. compound which, when it has set and hardened, would form a permanent seal between the glass and the frame or sash. The sealing compound would preferably be something superior to putty and more costly, but, on account of the relatively small amount required, could .be used without greatly increasing the cost.
Infact, the sealing grooves would be so small that it would be difficult to use anything of a putty consistency, but rather a substance of a more liquid consistency which would flow readily into the grooves.
However, the thought behind the sealing of the glass is not to be construed as suggesting the advisability of using putty on'a so-called puttyless sash, but rather that the puttyless construction, although particularly advantageous for low cost buildings, could also be used in homes and residences by sealing around the edges of the glass so as to make the sash entirely weatherproof and quite as durable as any other typeofsash.
Having set, forth a preferred embodiment of our invention, we claim:

A window sash comprising a frame forming an opening for a pane of glass, two of the edge .faces of" said frame on opposite sides of said opening being grooved to receive the corresponding edges of said pane of glass, one of said grooves being substantially deeper than 'the grooveopposite, and a spring mounted in the bottom of the deeper'of said grooves and bent into the form of a bow, the portion of said spring in contact' with the edge 'of said pane being beveled, whereby lateral pressure is exerted on said panetohold it against rattling in said frame.
