2 Claims. (Cl. 1Z0-56.4)

This invention relates to sash construction and particularly to sash having wooden frame members covered on their outer and inner surfaces with suitable sheet metal.

It is an object of my invention to provide a sash of Vthe class described having inexpensive wooden frame members, the outer and inner surfaces of which are'cov ered and protected by separate and spaced sheet' metal members whereby the transmittal of heat through the frame members of the sash is minimized.

Another object is to provide in a sash of the class described novel means for holding the window pane or panes in place in the frame, whereby the panes may be installed or replaced from the inside of the building without the use of putty or like sealing means.

A particular object is to provide such a sash with improved means forl fastening a glass pane in the frame comprising channel shaped resilient comprcssible members embracing the margins of the pane, confined in contact with a shoulder on the frame and resilient metal strips confining the channel shaped members and pane under lateral compression.

My invention also includes certain other novel features of construction which will be described and claimed in the following specication and claims.

Referring to the accompanying drawing which illustrates, by way of example and not for the purpose of limitation, a preferred embodiment of my invention:

Figure l is a fragmentary elevational view showing the outer side of one of my improved sash;

Fig. 2 is a similar elevational view showing the inner side of the sash;

Fig. 3 is a typical cross sectional view showing one of the frame members and covering sheet metal members, together with the coacting fastening and sealing means for the glazing panel or pane, and

Fig. 4 is a section similar to Fig. 3, showing a slightly modified form in which two panes are mounted in spaced parallel relation in the sash.

As best shown in Fig. 3, my improved sash has a frame comprising wooden members 5 which may be secured together at the corners of the frame in any conventional or suitable manner. Each of the frame members 5 is formed with a rabbeted inner margin providing a shoulder 6 extending around the inner margin or edge, preferably at or near the outer side of the frame. Also formed in each frame member 5 is a reentrant groove 7 spaced inwardly of the shoulder 6 to receive fastening members for the pane. Relatively shallow grooves 8 and 9 are formed in the outer marginal surfaces of each of the frame members 5.

Covering the normally outer side of each of the frame members 5 is a sheet metal member indicated generallyv by the numeral 10. This member is of subtantially channel shape so that it partially covers both the inner and outer edge or marginal surfaces of the member 5 and has a continuous ange 11 formed to engage the member 5 in the groove 9. Extending along theinner margin of the member is a flange 12 which projects at right angles r-r ICC to the shoulder 6 for engagement with the pane sealing member hereinafter described. The normally inner surfaces of each of the members 5 is also covered by a substantially channel shaped sheet metal member 13 having a flange 14 along its outer margin for engagement with the groove 8. The member 13 is formed with a second flange 15 which projects into the groove 7 formed in the member 5.

As shown in Fig. 1, the horizontal and vertical mem-bers 10 may be formed with mitered ends 10a at the several corners of the sash and these members may be secured to the wooden frame members 5 near each corner by means of nails or other suitable fastening members 16. In a similar manner, the horizontaland vertical members 13 (Fig. 3) may be secured to the wooden frame members at each corner by fastening members 17.

A glass or other suitable pane 18 fits in the sash in overlapping relation to the shoulders 8. Embracing each of the margins of this pane is a channel shaped resilient, flexible member 19 preferably constructed from compressible rubber or rubber-like material. This member is formed at its normally outer side with a groove to receive the flange 12 of the sheet metal member 10 and is adapted to be held under compression by means of a resilient sheet metal strip 20 having a marginal wedge portion 20a fitting snugly in the groove 7. When held in place in the groove 7 the projecting portion of the member 20 presses the resilient sealing member 'r9 against the pane 18 so that this sealing member and the pane are held under compression against the shoulder 6.

In the modification shown in Fig. 4 a second pane 21 is mounted in parallel relation to the pane 18 and is held at its margins in channel shaped resilient members 22 similiar to the members 19. Gtherwise, the construction shown in Fig. 7 is similar to that shown in Fig. 3.

Since the wooden frame members 5 are covered and protected by the sheet metal members, wood of a relatively low grade may be used in the construction of the main frame members and painting is unnecessary either for enhancing the appearance of the sash or to preserve the wooden members. Inexpensive light gauge metal may be used in the construction of the

members

10 and 13, thereby further reducing the cost of the sash compared with conventional metal sash or those depending on the rigidity and strength of the metal to impart the required strength to the sash. The

metal members

10 and 13 are preferably constructed from stainless steel or aluminum or other corrosion resistant metal.

By spacing apart the sheet metal members 10, covering the outer side of the wooden frame from the inner side covering members 13, both at the outer 4and inner edges of the frame members, I prevent the conduction of heat directly between these metal members which are subjected respectively to outside and inside tempferatures. This results in increasing the heat insulating value of the frame to a value comparable with that of an all wood frame, thereby` affording improved insulation as compared with construction wherein metal members embrace the wood members on all sides,A or as compared to all metal sash construction.

My improved construction is further advantageous in that the panes of glass may be mounted in the sash quickly and easily by the use of the resilient channel shaped members 19 and 22 and readily removable and insertable metal spring strips 20. The latter are readily removable and insertable from the interior of the building so that the glass pane may be installed and replaced with a. minimum of effort. A further advantageous feature of my invention resides in the fact that the sheet metal memlbers so reinforce the wooden frame members that the cross section of all sash members may be reduced, thereby making it feasible to provide a maximum of glass area for a Window of any given size.
