Goldberg, Denver, Colo. l 'Appiiati'on'necember 23, 1946,-se'r`ia1fN0i717,892 ji 1 y2 claims. (onzer-51) "This 'linvention' re'latI-is 5to 'limprovements l'in 'metal window' sashlaind has reference more particularly "tothe manner -of' effecting .joints be- -vwhich v"the sash is composed.

Metal window sash are made from steel or aluminum or any other` suitable metal, the most popular metal today being aluminum because this lcan be extruded, thereby -making itvpossible to get cross sections that would be diiiicultto-ob tain in any other way.

The several members of which the sash is formed are nearly always'con'nected by'we'lding,

i which vis'very satisfactory foremost joints, fb'u't in certain :places .welded connections of the kind that have usually been provided have some objectionable features `and itl is'the object of this invention to produce aconstruction in which the severalparts .maybe .interconnected ina fnianner f that obyiatessomeof the objections thatrca be* made to a Welded joint and which, also, vmay be effected in a simpler and cheaper manner.

'Ihis invention can be most readily understood when reference is had to the accompanying drawing in which it has been illustrated, and in which:

Figure 1 is a diagrammatic side elevation of a metal window sash showing the same divided into seven sections;

Figure 2 is a section to an enlarged scale, taken on line 2 2, Figure 1;

Figure 3 is a section on the same scale as that shown in Figure 2, taken on line 3 3, Figure 2;

Figure 4 is a View in the nature of a perspective showing the method of interconnecting two of the sash frame members;

Figure 5 is a cross section of frame member D.

In the drawing, in Figure l, one specific type of window sash has been illustrated in a general way. The outer frame members have been designated by "A and have a cross section like that shown in Figures 2, 3 and 4. The vertical side members are interconnected by a transom bar E that is positioned nearer the top than the bottom so as to form two openings of unequal size. The upper opening has been divided into four sections by bars D and the lower opening into three sections by bars C. The center opening, which has been designated by F, is for the reception of a hinged sash that has not been shown in the drawing. The other openings are usually lled by glass panes.

Referring now to Figure 2, it will be observed that the outer frame member A comprises a rectangular tubular center portion having an outwardly extending ange I0, and parallel therewith' is a flange `I I that is narrowerV thanl flange I Il'. Flanges 'Z'I 0 zand I I v.cooperate to'- secure the' sash toan. openingin a brick wall or Ain any y otherwallrtoI whichthe' sash is connected. EX-

This fisi heldy vin `placeby the usual 'putty :seal sld. :'Iransombar E- :has .a transverse'we'b I5 'i having oppos-itely extending an'ges I5. that f serve.y :as fabutments I -for itheA window` pane. Extending upwardly -a-short distance on the outside of member E is-v awall-or .;flange l1 vthat terminatesin -anoutwardly extending.; and-downwardly 'Haring ledge 7I 8., Atseveral `isidivided into sections-by short pieces iofspe- .callyf ,constructed framefrnembers 19, which has been shown in section in Figure 5. It will be observed that these frame members D comprise a central rectangular portion formed from two web walls I9 that are spaced apart a short distance. Along one edge of the tubular web are two flanges 20 that extend equal distances from the center portion and along the other edge are anges 2| that extend shorter distances. The lower opening is divided into three sections by frame members C whose construction is quite clearly shown in Figures 3 and 4. These members have a rectangular central web formed by walls 22 that are spaced apart a distance equal to the distance between the outer surfaces of webs I9 of frame members D. Flanges 23 extend equal distances from both sides of web 22, as shown most clearly in Figure 4 and narrower ilanges 24 extend from the web 22 along its outer edge. Connection is made between frame members A and C in the manner shown in Figure 4 from which it will be seen that the inner web 25 of member A has a rectangular opening through which web 22 extends. The ends of `web walls 22 are bent outwardly so as to form interlocks like those designated by reference numeral 3l. In order to make it possible to rivet the ends of iianges 22 in the manner shown in the drawing, web 28 of frame members A is provided with a hole 29, through which the riveting tool may be introduced. If desired, the interlocks 3| may be secured to web 25 by welding in addition to the interconnection shown. Transoxn bar E has its web I5 provided with rectangular openings of a size to receive the spaced Walls 22 of frame members 'C whose ends are then bent outwardly or riveted as indicated at 301. Members D are secured in position between the upper frame member A and the transom bar in the manner shown in Figure 3. It will be seen that the web walls I9 project between the upper ends of web walls 22 of frame member C. The spreading or rivet-` ing of the web walls I9 is eifected by a tool extending through the opening 29, which is -pro` vided especiallyfor this purpose.

Referring now particularly to the joint between members C, D and E shown in Figure 3, it will be observed that web walls 22 extend through an opening in web I5 and receive between them web walls I9. A small amount of welding can be employed to interconnect the parts if desired.

With the ordinary construction in which the parts are butt welded to the outer frame, it

cut away some of the material that results from the welding operation, and besides this, it is more diicult and requires more time and eiort to interconnect the members in the ordinary way than with the construction shown on the accompanying drawing.

from the usual butt welding operation.

Having described the invention what is claimed as new is:

1. A window sash frame member for use in f*making metal window sash, comprising, a substantially rectangular tubular web, one side having a window pane abutment flange along one edge and a putty abutment ange along the other edge, the web wall between the flanges having a rectangular opening for the reception of a web of another frame member, the opposite web wall having an opening in register with the rst opening for the introduction of a riveting tool.

2. In a window sash comprising two frame members each of which has two parallel `flanges spaced apart and interconnected by a tubular web of rectangular cross section, in which one frame member is connected with the other in substantially right angular relation, forming a T, the frame member forming the top of the T having one web wall provided with a transverse opening ,adapted to receive the web of the member forming the stem, the ilanges of the latter being cut back to permit the web to project through the opening in the web of the top member, the

' other web wall of the top member having an often becomes necessary to employ a chisel to opening in alignment with the opening in the other wa11for the reception of a riveting tool, whereby the ends of the web walls of the stem member may be spread apart, into web overlapping position, the outward flared ends forming `means for holding the frame members in assembled position.
