Application led November 19, 1914. Serial N o. 872,948.

lwhich the followingis a specification.

This invention relates to wooden sashes employed in glazing windows or doors.

rThe object of the invention is to produce a sash so constructed and arranged that the glass may be introduced and removed from the inside of the sash, or the interior of the building in which it is employed, thus, in the case of a window, obviating the necessity of removing the sash from the windowframe, while at the same time the sash shall be water-tight, neat in appearance, and protected against decay from the action of moisture.

To the foregoing ends 1 employ a sash having members rabbeted in such a manner as to provide inwardly-directed shoulders, against' which the panes of glass are secured by molding-strips, and. in connection withV this arrangement 1 employ certain features of construction, hereinafter described, for rendering the joints water-tight, and for excluding moisture from points in the sash which ordinarily are most subject to decay.

lThe invention is more fully set forth in connection with the following description of the illustrated embodiment of the invention.

1n the drawings :Figure 1 is a partial front-elevation of a window-sash embody" ing the present invention; and Fig. 2 is a vertical section, on the line 2-2 in Fig. 1, looking from right to left in the latter ligure.

bThe invention is illustrated as embodied in a window-sash, having the usual stiles 3, and top vand bottom rails l and 5, :cesped tively. The illustrated sash is also provided with a horizontal bar 6, although the invention is equally useful in a sash inwhich no bars are employed. The sash is also shown as provided with upper and lower panes of glass 7 and 8, respectively.

The lower rail 5 is rabbeted on the inner part of its upper surface, so as to produce an outer flange 9 and an inner horizontal surface 10, the inner surface of the flange providing an inwardly-directed shoulder 1 1. The flange is also preferably beveled at its outer angle, as shown. A novel feature of the present construction resides inthe use of a strip 12 of thin sheet-metal, which con-` f orms closely to the flange 9, having a ver tical portion 13 which'is 'seated against the shoulder 11 andl extends down to the surface 10, as shown in Fig. 2. The inner margin 14 of the strip 12 is bent upwardly, parallel with the part 13, thus producing a slot into which the lower edge of the window-pane 8 is introduced. To hold the pane securely inplace, without dependence upon the thin sheet-metal, a molding-strip 15 is employed, this strip being screwed or otherwise fastened to the rail, and engaging the inner surface of the part 14 of the sheet-metal. j

To secure the metal firmly upon the wood, and prevent the admission of moisture between the metal and the wood, the outer margin 17 of the metal is bent inwardly, at an upward inclination, and buried in the wood, as shown in Fig. 2.

Before seating the glass in place a suitable cementitious material, such as whitelead'thinned with oil, .is preferably placed in the slot provided by the metal strip 12. 1t will be apparent, however, "that, even in the absence of such cement, the upward extension of the inner margin of the metal tends to impede the free entrance of moisture which may find its way between the glass Vand the metal.

For further protection against leakage, and also for the purpose of providing a neat finish on the inside of the sash, the moldingstrip 15 isrecessed in its outer surface, so as to receive and fit over the margin 14 of the sheet-metal, this recess producing also a narrow flange 16 on the molding-strip, which is brought into direct engagement with the glass and may be pressed against it in such a manner as to make a practically water-tight and air-tight joint.

The stiles 3 are rabbeted in substantially the same manner as the rail 5, so as-vto produce outer flanges 18. In order to provide an overlapping joint, which will tend to eX- sev clude the admission of water between the n abutting surfaces of the stiles and the rail, the flanges 18 are cut away at their lower ends, to provide recesses 19 in which the ends of the flange v9 project. In Fig. 1 the rail and one of the stiles are shown as provided with the usual mortise and tenonfor fixing them together, but the tenon is partly withdrawn from the mortiseto show the arrangement of the parts just described.

For further security against the admisj lsion of moisture between the stile and the rail, the metal strip l2-j is made 4kslightly longer than the flange9, so as to have a narrow margin 2O projecting at each end there` I of, and when the stiles and the rail are mortised together the edges of the sheet-metal are buried in the wood of the stiles. rIhis Varrangement provides, further, for4 the maintenance of a close joint notwithstanding slight changes, in the relative length of the rail and the metal strip, resulting from the effects of heat land moisture.' A

In connection with'thestiles and the upper rail il ofthe sashit is unnecessary to employ a metal strip, although this Ymay be donek if desired. At these points I'preferably employ simpler means for maintaining a water and air-tight joint between the glass andfthewood. F or this purpose the stiles and'therail are so rabbeted as to produce flanges 18, and 21, respectively, having inuf"t'1dlydirectedr l shoulders which are slightly kbeveled or undercut, as shown in Fig. 2. Accordingly, the glass engages the shoulders only at their extreme angles, narrowV tapering recesses 22 being left between the'parts, and these recesses serv-e to retain suitable cementitious material, such as white lead, which is introducedA before Vthe panes are'r placed in. position. Moldingstrips 23, fixedv to the ,upper railand the stiles, press the glass firmly against the shoulders and j the cement thereon...

Where the sash is provided with a horizontal bar, as illustrated, the joints between the glass and the bar rmay be madein substantially the manners hereinbefore 4described, the joint on the upper surface of the bar being similar to that on the lower rail 5, while the joint onr the lower surface may be similar to that on the upper rail Ll. As showmtheb'ar '6 is provided with a sheetmetal stripp2ll fixed in place in the same manner as Ytlie strip 12. g In this case, however, the inner margin 25 of thefmetal is shown Vas extended somewhat higher than the'part'of the metal which lies over the outer'flangefof the bar, so that even in the absence Qf'anycement between the glass and the metal'k itis impossible for water to flow between the Aglass and the metal. In this casezthe molding-strip 26 yextends only tothe upper'edge of the metah and is not recessedv to receive the latter;

l In the case efthe bar, as in thatofthe lower rail 5,the metal strip 24 is somewhat l, Y. longer than the-flange, so as to be embedded,

at its upper and lower 'edges ink Vthe mate-v rialY of4 'the stiles, and thus secure av water-V tight jointbetween'ithese parts.

5,. The ISt ea-mai employed in al@ adv@ described/construction be either of comparatively.A rigid material, suchV as'hard brass or. zinc, v`or -it may Yof soft flexible material, such Vas" copper or lead. lIn the vshoulders of the sash, being finally secured in place by fixing the molding-strips to the sash-members. There flexible metal is employed, however,.it may be preferable not to bend the margin 14-v or 25 of the metal upwardly until the glass has been placed in the sash. In'this manner provision may be made for conforming the metal closely to glass of various thicknesses.

When it is vnecessary to replace a broken pane thi's'can be `conveniently done from 'the interior of ythe building in which the sash is used, and without lremoving the sash from the window-frame. For this purpose it is necessary only to remove the molding-strips, the broken glass, and the cement from the sash, apply fresh cement, introduce the glass, and replace theinolding-strips. If the last operation is carefully performed, so as to press the parts all closely together, the use of cement may be entirely dispensed with, as the metal strips prevent the entrance of moisture beneath the lower edges of the panes, as before stated, while they beveled shoulders, on the stiles and other parts of the sash, provide for the production of a tight joint between the glass and the wood when forced together with a moderate pressure. The metal strips, in addition to sealing the sash against leakage of moisture and air, protect the wood against decay at the points where it is most subject to the action of moisture, namely, upon vthose surfaces on which moisture is likely to stand after a rain-storm, or in consequence ofthe melting of ice and snow.

My invention is not limited to the embodiment thereof hereinbefore described and illustrated in the accompanying drawings, but may be embodied in various other forms within the nature of the invention as it is defined in the succeeding claims.
