(Cl. 'i2-99) l1 Claim.

This invention relates generally to window frames and sash, and more particularly to concrete and metal window frames and sash.

All devices of this character made according to the prior art and with which I am familiar have been so constructed that they are not water tight and quickly deteriorate and rot if made of Wood, and rust if they are made of metal. It has been found that window frames and sash made of the same metal tend to adhere to each other after rusting, thereby making the frame and sash of little value. Most of the frames now made are not reproof and they provide no close tting points of contact between the sash and the frame. Wind and water easily penetrate the sash and frame in present constructions. These prior frame and sash constructions have been costly in manufacture.

It is accordingly an object of my invention to overcome the above and other defects in window frames and sash construction and it is more particularly an object of my invention to provide Window frames and sash which are easy to manufacture, cheap in cost, and easy to install.

Another object of my invention is to provide a window frame and sash of different materials to prevent adherence to each other.

Another object of my invention is to provide a window frame and sash which is windproof and waterproof.

Another object of my invention is to provide a window frame and sash which has close fitting points of contact between the sash and the frame.

Another object of my invention is to provide a window frame and sash whereby dead air spaces aregprovided to prevent wind passing the sash.

Another object of my invention is to provide a plurality of points of contact between the frame and the sash.

Another object of my invention is to provide means for securing a y-screen to the window frame.

Another object of my invention is to provide eicient means for securing the frame in place in an existing window frame.

Another object of my invention is to provide a novel method of constructing a concrete window frame and a metal sash therefor.

Other objects of my invention will become evident from the detailed description taken in conjunction with the accompanying drawings in which:

Fig. 1 is a rear elevation of my novel frame and sash.

Fig. 2 is an end elevation of the frame shown in Fig. 1.

Fairview Town- Fig. 3 is a cross-sectional view taken on the line 3-3 of Fig. 2.

Fig. 4 is a cross-sectional view taken on the line 4-4 of Fig. 1.

Fig. 5 is a fragmentary cross-sectional view showing the means for securing the sash hinges to the frame.

Fig. 6 is a fragmentary cross-sectional view showing the bottom portion of the sash in contact with the raised shoulder of the fra-me.

Fig. '7 is an end elevational view showing grooves in my novel window frame for securing the frame in a wall or the like.

Referring to the drawings, Figs. 1 and 2 show a concrete window frame I having a metal sash 2 hingedly connected therewith by hinges 3. The hinges are secured to the concrete frame by bolts 4 embedded in the concrete frame I. The bolts 4 are provided with nuts 5 to secure the hinges 3 on the bolts 4. Two nuts are used on the bolt 4 in order that it may be secured to the sash during the operation of pouring the concrete for the frame I therearound. The ofi-set cut-away portions immediately adjacent the margins of the upper bevelled portion 6 of the frame I engage the T-member 1 of the sash 2 to provide two points of contact for the upper and side portions of the sash 2. The side portions of the sash 2 and the frame I are of the same construction as the upper bevelled portion. It will be evident that a dead air space is provided between the bevelled portion 6 of the frame I and the T-member 1 of the sash 2. The bottom T-member 8 of the sash 2 moves over the uppermost part of the raised shoulder 9 of the frame I and the off-set cut-away portion II immediately adjacent the margin of the bevelled surface I0 declining into abut-away portion II. It will be seen that a dead air space is also provided on the bottom portion of the sash thereby providing a dead air space around the entire periphery of the sash. Suitable reinforcing members I2 are disposed in the frame I. Grooved surfaces I3 are provided on the outer periphery of the frame I in order to secure the frame I in place in a new installation or in the place of an existing installation. Grooves I3 are not absolutely necessary to carry out the spirit of my invention, but are merely provided as a holding means 'for the frame when cemented into an outer frame. Any suitable locking means lsuch as I4 may be used to hold the sash in locking position. The outer portion of the concrete frame (not shown) may be provided with a bevelled surface, thereby causing a wedging action upon installation of the concrete frame I. Members I5 are disposed in a vertical plane interiorly of the concrete frame l and on the sides thereof to provide means for installing a screen. Other means than those shown may be provided for securing the hinges for the sash to the concrete frame such as welding hinged members onto embedded members in the concrete frame I.

In the manufacture of my novel concrete window frame I and metal sash 2, it will be evident that a minimum number of forms are required.

The window frame l is of suillcient strength of itself to eliminate the -use of angle-irons, lintels or other supporting devices ordinarily required over window openings in a wall. Small metal strips (not shown) are provided adjacent the T-member forming the periphery of the sash 2 to provide the bevelled portions 6 and I6 to provide two points of contact betw-een the sash 2 and the window frame and also provide a dead air space.

It will be evident that I have provided a method of manufacturing concrete window frame and metal sash which is very simple and utilizes the metal s-ash 2 as part of the mold frame. The concrete window frame l and the sash 2 are simple in construction and provide two points of contact between the sash 2 and the window frame l, thereby making the sash and frame impervious to wind and rain.

Various changes may be made in the specific embodiment of the present invention without departing from the spirit thereof or from the scope of the appended claim.

What I claim is:

In a Window construction, in combination, a rectangular frame including upper and lower, spaced, parallel, horizontally extending members and a pair of spaced, parallel, vertically extending concrete side members, all of said members being integrally cast and forming a unitary structure, said structure including an outer and an inner face and external and internal peripheral surfaces, the outer face of all of said members `having a marginal seating surface, said marginal seating surface being situated adjacent the internal peripheral surfaces of the members of the structure, a second seating surface at right angles to and offset laterally inwardly from said marginal seating surface and spaced inwardly therefrom on the inner peripheral top and sides of said concrete frame, a transverse marginal beveled surface directed inwardly from said marginal seating surface and connecting said marginal seating surface and said inner seating surface on the top and sides of said concrete frame, a metal rectangular frame having a -T-shaped cross section comprising a crosspiece and an inwardly extending ilange, one side of the crosspiece of said T-shaped cross section of said metal frame sealingly engaging said marginal seating surface and said inwardly projecting flange on said T-shaped cross section of said metal frame sealingly engaging said inner seating surface at right angles to said marginal seating surface, a closed marginal chamber being dened between the inwardly directed flange of said T-shaped cross section of said metal frame and the transverse marginal beveled surface of said concrete frame, hinged means hinging said Y metal frame on said concrete frame, and means securing said metal frame in engagement with the above mentioned seating surfaces on said concrete frame.
