METALLIC WINDOW AND DOOR FRAME I Originl Filed Jan. 3, 1938 2 Sheets-Sheet Z Hum 96 W i0 and method of manufacture Patented Oct. 29, 1940 UNITED STATES PATENT OFFICE 9 Claims.

past, there has been an inmanufactured and sold for use on small dwellings To satisfy this demand a number have developed and are at to the trade, metallic frames and the like. of manufacturers present time offering in which the various parts, such as the head,

jambs and sill are individually stamped or cast and finally secured together at the corners by providing overlapping and/or interlocking portions which are secured together by spot welding and other means. While these frames possess many advantages not found in the older forms :5 of wooden frames and sashes, they are still open to the objection that their cost is prohibitive due l to the complications encountered in their manufacture. It is, principal object .of the present invention to provide an article in the form of window-and door frames in which the parts forming the head, jambs and sill are of substantially identical and uniform cross-section and which, because of this characteristic, can be formed from a single strip of metal and thus greately simplify the manufacturing operations and provide a frame for windows and/or doors constructed entirely of metal that can be manufactured at a price competitive with the wooden frames heretofore supplied for this purpose.

Another object of the invention is to provide a new and novel improvement in ,metallic frames which will facilitate the manufacture of the frames from a continuous preformed strip of sheet metal.

A further object of the invention is to provide 1 an improved method of fabricating metallic frames for double hung windows and doorways 50 which will greatly simplify the manufacturing operations by eliminating the time consuming effort which is now necessary to properly align and secure the top, jambs and sill of the frame together in accordance with the prior art I methods.

Divided and this application January Serial No. 251,330

Other objects and advantages of the invention will be in part pointed out hereinafter and in part evident to those skilled in the art as the description thereof proceeds.

For a better understanding of the reference should be had to the accompanying drawings wherein there is shown, by way of illustration and not of limitation, preferred embodiments thereof.

Figure 10 shows a structed in accordance with the present invention and from which a metallic window sash may be constructed, and

Figure 11 is a fragmentary view showing a strip of the latter type as bending operation to complete a corner similar to that illustrated in Figure 10 of the drawings.

The novelty of the present inventionin addition to residing in the production of a metallic frame forming strip conmitred prior to the 50 frame from a single piece of sheet metal in a I novel and inexpensive manner also resides in the particular characteristics of the strip which when mitred in accordance with the invention provide two spaced and uncut portions upon which the strip may be bent to bring the ad- Jacent portions thereof at the corners into exact meeting relation by virtue of the fact that the two spaced uncut portions function as bendable indexing ties in a manner similar to that obtaining with a door hinged upon two spaced hinges.

In my prior above identified disclosure, wherein the frame is disclosed as formed with a single outwardly extending side flange, means must be provided to bring the adjacent parts of the frame into meeting relation during the bending operation, whereas with the present invention the strip can be easily bent after being mitred without requiring any special means to insure a meeting of the inner light opening donning portion of the frame or the side walls thereof into exact meeting relation. g

The particular frame structure illustrated in Figures -1 and 2 of the drawings is of simple conand an upper sash II, the light opening defining wall II in this embodiment of the invention is shown more clearly in Figure 2 as having a contrally disposed smaller channel it that provides an inwardly extending rib or parting strip against which the sashes l4 and it are adapted to be held and slide.

light opening of the frame is also shown as havin it into which removable retaining 2i! are respectively inserted. When strips l I and ing strips I9 and 20 are inserted in their respec tive channels l1 and II it will be seen that the sashes H and I5 will each be provided with spaced guides between which they may freely slide in accordance with the practice in the conventional double sash window frames.

At this point it will be evident that while the sash retaining strips IO and 20 are shown as provided in the head or top of the window frame it, the strips may, if desired, be omitted at this point and at the bottom of the frame, if desired, the channels l1 and I! may be provided with a filler strip which extends flush with the inside surface of the light opening defining wall ll of the window frame I0. Further it may be said that while the channels I! and ii are not necessary at the top or sill of the frame, since they do fully justified as it makes possible the construction of the frame from a continuous single strip of sheet metal of uniform cross-section.

the strip is mitred and ,inside and out two oppositely disposed channels" "and" meeting relation. In this figure of the drawings the mitre out, designated by the numeral Ii, is shown as extending through the inner light opening defining wall H of the frame and into the inside and outside flange forming portions II and II thereof to a point closely adiacentthe outer edges of these latter flange forming portions where small uncut portions of these flanges, deslation when the mitre cuts II are fully closed. To complete the frame there then only remains the necessity for securing the meeting ends of the strip which complete the rectangular frame. vWith a frame of this character the builder need only prepare the wall of the building with properly spaced stringers and/or studding between the side forming flanges II and If to which the frame can be finally nailed and/or otherwise socured.

In Figures 4 and 5 of the drawings there is illustrated of the invention which I4, is shown as having a relatively wide central channel 2! which provides what may be otherwise termed an inwardly extending cleat 20 against which a door, designated by the numeral 21, may be mounted. The clcat fl is made to extend out sufliciently far from the wall 14 of the frame to form a stop for the door and at the same time this cleat is so proportioned in width that it will not provide an obstruction at the sill of the frame which, as contemplated by the invention, is of the same cross-section as are the lambs and top of the In this embodiment of the invention the mitre cuts it are shown as extending through the portion 24 and the olcat ll of the frame and into the spaced portions II and fl which form respectively the While which is particularly adapted for window frames having double hung sashes. As here illustrated, the strip from which the frame is constructed is first folded and/or bent longitudinally to provide a main channel section having a light opening bottom of the main channel section. the spaced parallel flanges Ii and 32 Each of outwardly extendingside forming -x, s e ts i th s items...

After the strip has been rolled into this frame into right angled meeting relation. The Configuration it is Provided w mitre cuts, novelty here, like in the previously described which extend through the light opening defining frames, resides in the arrangement of two uncut wall 30 and into the side flanges 3| and 32 to portions in the strip at points spaced laterally a point beyond the ribs 34 and 35 in these porfrom each other and outwardly beyond the light tions of the frame and thus leave two spaced 1mopening defining wall ofthe frame so that when out and bendable tie portions 31 and 38 which, as the strip is bent upon these uncut portions the 16 has b en he b pointed Out, function to inner and side wall surfaces of the frame will be 1 retain the a a n portions of the strip together brought into exact meeting relation when the and bring the surfaces thereof into exact meetstripis bent to close the mitre cuts. the relation, as illustrated in Figure, 'l of the It will be of importance to note that this strucd a when the Strip has b bent upon ture provides two transversely aligned connecting 20 these uncut tie D t to Complete the ties at each mitre cut and that, since each mitre 20 When the Window f am s constructed from cut extends entirely through the channel base or s ip f m with the ribs qfiias last light opening defining wall and outwardly into above described, ese ribs in addlhoh to the two opposed side flanges, each tie will be disviding a rein in the Sides of the frame posed inthe plane of the side flange of which it as at these points also furn h a heading t which is a part.
