IN VEN TOR. Walter Brauzr Patented Dec. 9, 1952 attics METHOD OF MAKING WINDOW FRAMES Walter Brauer, Corpus Christi, Tex.

Application This invention relates to Window frames and more particularly but not by Way of limitation to the method of forming light weight metallic window frames.

The invention is generally concerned with the forming of a window pane frame from a hollow piece of light weight metal, such as aluminum or the like, so as to provide a groove for receiving the glass pane without the necessity of bolting several pieces together. It is well known that in metal window frames of conventional use that it is usually necessary to form the frame of several sections which must be bolted together for maintaining rigidity and to provide the necessary groove for the pane. Furthermore solid light weight metal bodies have been utilized for making window frames wherein the solid body is provided with a machine groove for receiving the pane.

It is an important object of this invention to shape a hollow metal casing in such a manner to provide a groove for receiving the window pane whereby the metal of the hollow casing and its inherent strength are not only retained but will be made much stronger and rigid because of the shaping operation.

Another object of this invention is to provide a light weight metal Window frame of such a shape that will support a window pane in a firm and rigid manner.

And still another object of this invention is to provide a light weight metal window frame from square tubing formed with a groove therein for receiving a pane so that the opposed outside corners of the square tubing will contact the sides of the window pane disposed in the groove.

Other objects and advantages of the invention will be evident from the following detailed description, read in conjunction with the accompanying drawings, which illustrate my invention.

In the drawings:

Fig. 1 is an end view prior to forming.

Fig. 2 is a similar view after the forming operation.

Fig. 3 is a sectional view of Fig. 1 showing the glass disposed in the pre-formed frame.

Referring to the drawings in detail, reference character 2 designates a metal body preferably of aluminum or other light weight metal (but not limited thereto) which is preferably a square or rectangular configuration. It is desired to preform any desired length of the tubing 2 for utilization as a window frame. The pre-forming operation may be done by any suitable method such as a press bar 4 actuated by any suitable February 21, 1949, Serial No. 7.7.4.93 1 Claim.. (01. 2 9-4 48) means (not shown)" The substantially square" body 2 (as'shown) is disposed beneath the press bar so that the top portion 6 of the body is disposed in a substantially media position beneath the bar 4 whereupon a down stroke of the bar against the flat top portion 6 will shape the body 2 into a configuration substantially as shown in Fig. 2.

The pressing of the bar 4 will distort the corners 8 and ID of the body 2 to form the centrally disposed groove [2 for a purpose as will be hereinafter set forth. It will be apparent that the press bar 4 for shaping the groove I2 will move the outside corners 8 and I0 into substantial contact with the press bar 4 prior to its upper stroke, at the same time providing a substantial curvature M at opposite sides of the body 2. The forming of the window frame from aluminum square tubing or the like is not necessarily limited to a press bar operation as disclosed, but will be apparent that other forming operations can be utilized such as any suitable extrusion through dies or the like (not shown).

In Fig. 3 is shown a window frame body 2 having the formed groove portion I2 with a glass pane l6 disposed therein. Any suitable elastic glazing compound l8 may be disposed in the groove l2 to assist in maintaining the glass pane It in the groove l2.

It will be apparent that the present window frame construction from hollow square tubing or the like decreases the overall weight of the frame without the loss of any rigidity therefrom. Any desired length of the frame may be formed as shown and the various sections so formed may be welded together to provide substantially any desired shape or configuration of a window frame. It will be apparent that the window frame of the present invention may be utilized particularly in louver type windows, that necessitates a pivoting or angular positioning of the frame. The inherent rigidity in the present frame assists materially in maintaining the rigidity of the frame during the opening and closing of louver type windows.

From the foregoing it will be apparent that the present invention contemplates a light weight metal window frame which may be formed from any suitable irregularly shaped tubing, such as square or rectangular tubing, having a centrally disposed recess or groove for receiving a window pane. Furthermore the bending of the top side portion of the tubing is such to position the outside square corners into contact relationship with the bending means and simultaneously providing a curvature at the opposite side portions of the tubing thereby providing a one-piece body which will maintain its inherent rigidity.

It will also be apparent that the tubing may be of any desired dimensions dependent upon the size of the Window frame required. Furthermore, during the pressing operation of the top plate 6 the light-weight metal is elongated to permit the forming of the curvatures at the opposite sides of the groove portion.

Changes may be made in the specification and drawings without departing from the spirit of the invention within the scope of the following claim, as set forth.

I claim:

The method of making window frames from light-weight metals which consists of utilizing a substantially rectangular shaped tu'bular mem- 'ber, forming a centrally disposed groove in the top wall of the tubular member by pressing a bar thereagainst until the corners of the top wall are in contact with the sides of the bar. and forming curvatures at opposite sides of the grooved portion simultaneously with the elongation of the top wall of the tubular member.
