. vide a sheet metal window structure which .isof simple and lightweight constructionand 5 yet strongand durableas well as stifi .and

rigid; which, in use, is easily opened and closed and yet in closed positionprovides a weathertight construction; and whichis easy and comparatively inexpensive to manufac- 110 ture. The present application is .a division of my copending application formetal window structure and -method 'of making the same, filed April 30, 1928, Serial Number 274,122.

One of the principal objects of the invention resides in the manner of constructing the sash and window :frames whereby the problem of production is simplifiedand the resulting construction, while-of light weight, is so stiff, strong and rigid as not to be liable to be rackedor strained in use.

In general these features and objects are obtained-by forming the window frame of a V bases provided therefor and formed integral single piece of metal, the major structural elements of the window frame being-shaped and formed .by a drawing or cuppingoper-ation which fashions theseelements fromthe metal of-the one piece blank in such manner as to produce a'structure-of marked-strength and rigidity. Following thecuppingoperation, the outside edges of the blank are trimmed or cut to form the .edges of the frame and to outline the stock subsequently shaped to constitute the appurtenances of the window frame, such as=hinges,strengthening or reinforcing plates, stiffening wings, and

the like. After'thisa portion-ofthe blank within the confines of the frame ;members is cut away to provide the frame opening membersand at le'ast one of the margins of the windowopening is shaped to provide a water shedding weather strip.

Thesame generic features are to be found in the construction of the sash frame, the major elements of the-sash frame, "being'of a single piece sheet metal construction,

cupped or drawn to shape, and having in- V I verse section taken onlme 212 of Figure ;1

tegral therewith the structure providing seats for the window glass-employed and the Along its outside edges, the sash frame has its appurtenances integrally formed there with.

The structural elements of'both frames are r y of cupped formation and have angularly disposed frame members of continuous or 'integral construction and each framemember so formed has a body portion provided with edge flanges, the flanges of the side frame rails all of the frame members having :their body portions and flanges designed to .interfit andengage in the assembly to provide weather excluding members. Further, the hinge ears, reinforcing plates, stiffening wings, and weather stripping (are all integral with the frame members. Thus,the window frame and all its appurtenances are constituted of one piece of vmetaland the sash,

frame is also of onepiece construction-except ,forthe two mullion or finishing strips which are applied and welded in position on the with .the sash frame.

Due to'theangular members, to their integral construction and to \theircupped or drawn formation which not only upsetsbut also flanges themetal,

The window frame and the sash frame embodying the present invention are each constructed from a single piece of metal in accordance with the method fully described :and' claimed in my c-opending application above referred to, and reference is made to such application for a full disclosure of the method of producing these frames. It is to be understood, however, that the present invention is not restricted to this particular "method of producing these frames although preferably the frames are produced by the novel method referred to.

Referring more particularly to Figures 1 to 6, inclusive, it will be seen that the window frame W, embodying the present invention, is of rectangular form and comprises

side frame members

6 and 7 and end frame mema weather strip 5 is integrally formed. The

side frame member 7 (see Figures 2 and5) also has a body portion 10', and outwardly directed edge flange 11, and an inwardly directed edge flange 12'.

,As shown in Figures 3 and 6, the end frame members are of similar construction and each includes a body portion 14, an inwardly directed edge flange 15 and an outwardly L directed edge flange 16 on which a stiffening rib designated generally atv 1 is integrally formed. 6O

- edge flange 16 and also'has a section I extending at right angles to the section l as Shown in Figure 3. The wing 1 not only has af'stiflening and reinforcing function but 7 Each stiflening rib 1 has a section 1 bent down flush against the outwardly. directed its outwardly directed section 1 aflords a gauge or stop operable when the window is put into place in the building to indicate and limit the extent to which the structure of the desired, the ends of the weather strip 5 may be connected to the body portions 14 of the end members 8 and 9 by short, appropriately curved connecting

pieces

5 and 5 spot welded to the ends of the weather strip 5 and to the body portions 14 of the end members whereby to provide a complete weather repellant stripping or structure along the bottom or lower side of the window. The

pieces

5 and 5 are constituted of the scrap resulting from the formation of the wind-ow frame from a single piece.

The outwardly directed edge flange 11 of the side member 7 is employed as a hinge rail and in order to stiffen and strengthen it and better adapt it to perform this function a hinge rail stiffening plate 2 is integrally formed with and bent down flush against the edge flange 11'. Integral with the stiffening plate 2 are hinge ears 3 rolled to the form shown in Figure 5 in which portions of the ears engage the underlying outwardly directed flange 11'.

The sash frame designated generally at S is also drawn 0r cupped from a single piece of metal which is appropriately trimmed and shaped. As shown in Figures 1 and 7 to 10, inclusive, the sash frame S consists of

side frame members

35 and 36 and

end frame members

37 and 38, all constituted of a continuous and integral piece of metal and each having a body portion 39, an outwardly directed edge flange 40, and a crimp or channel 30 around its inner margin, each crimp or channel having an inwardly directed edge flange 41. In addition, there are integral cross members constituted by the flanged channels or crimps 31 (see Figure 7 and 9),

whichbrace and stiffen the

side members

35 and 36 of the sash frame and which provide channels or sockets for the reception of doubled mullion strips 43, the mullion strips 43 being inserted in the channels 31 and spot welded thereto as indicated at 47 (see Figures The flanges 41 of the inner man 1 and 9). ginal channels or crimps 30 and the flanges of the cross channels 31 afford seats to which glazing is applied and secured by putty or other suitable means.

The structure of the sash frame is completed by bending or rolling' frame is shown in Figures 1, 2 and 3. As illustrated in these Figures the hinge ears 3 and are brought into registration and pivotally secured together by hinge pins preferably in the form of heavy cotter pins of resilient metal which may be readily inserted or removed but which are releasably held in position when inserted by Virtue of their frictional engagement with the hinge ears. This mounting permits the sash frame to be swung into the window frame as shown in Figures 1 and 2 at which time the outwardly directed flanges 40 of the sash frame members fit flush against and overlap the outwardly directed flanges 11, 11 and 16 of the window frame; the body portions 39 of the frame members of the sash frame project into the opening of the window frame; and the crimps or channels 30 formed around the inner marginal edge of the sash frame bear against the inwardly directed flanges 14 of the end frame members 8 and 9 and against the inwardly directed flange 12 of the side member 7 of the window frame, thus providing a weather tight joint entirely around the frames at the inner side and a second weather tight joint entirely around one side member and two end members at the outside of the frame. A weather tight joint is also provided between the lower side member 6 of the window frame and the lower side member 35 of the sash frame but is constituted by the weather stripping 5 which is angled inwardly and upwardly toward the body portion 39 of the side member 35 of the sash frame so as to throw rain or water, that may drip down or be blown in against the frames, out to the eXte- I101.

The glazing G, applied to the seats afforded by the flanges 41 of the channels or crimps 30, is secured in position by spring glazing clips C and putty P and the putty which is forced into the channels 30 provides a cushion for the glazing.

A latch may be provided on the inside of the frame member 35 to coact with a keeper 61 fixed on the frame member 6, as shown in Figure 1.
