Application filed February 23, 1922. Serial No. 538,676.

To all whom t may cof/wom:

Be i-t known that I, JACOB WASSERBERGER, a residentof New York city, Bronx county, New York, and a citizen of the United States, have invented certain new and use` ful Improvements in Metal Windows, of which the following is a specification..

This invntion pertains to the structural relations of the sash and jamb of af metal window and has forits object to provide for eective prevention of the passage of air between the jamb and the'sash without.

increasing materially the cost of construction or'the difficulty of assembling the sash and frame and without interferingwith the free movement of the sash. The invention will be more fully explained hereinafter with reference to the accompanying drawing in which it is illustrated and in which- Figure 1 is a view in horizontal section through one side member of a window frame or jamb constructed in accordance with the invention, portions of the two cooperating. sashes being also sho-wn. Figure 2 is a View of theI same partly in elevation and Ypartly in vertical section.

Figure 3 is an edge view of a portion of one sash, the lintel or frame head being indicated in section.

In the embodiment of the invention shown the side Jiframe member or jamb or weight box 5 is shown as composed mainly,as usual, v

of a single sheet of metal bent into substantially rectangular form, but having, in the present instance, its edge portions 6, 7, bent inward and then in parallelism with the face of the jamb, as clearly shown in Figure 1. The opening between the edge portions of the jamb is closed by a strip which has a central projecting portion 8` standing nearly Hush with the faces 23 of the j amb, and lateral [langes 9, such strip being secured to the edge portions 6 as by screws 10. To the central rib or projecting portion 8 is secured, as by screws 14, which may enter bosses 12, a strip 13 which partly overlaps the jamb pockets 15, leaving comparatively narrow slots to receive the iianges of the sashes.

Each side member of each sash is formed of two members 17 and 18 which receive the glass 16 between themand are suitably bowed at 19` are brought together as at 20 v22 to co-opera-te with the corresponding edge of the flange 9 of the central member so as to form a close joint therewith. It will be noted that the plate or lstrip( 13 leaves be tween its edges and the opposing angles of the main jamb member, 'slots or channels in which the sash flanges may move with a free sliding fit.

The co-operation of the oset portions 22 of the sash anges with the flanges 9 and the sliding fit of the flanges in the slots described together eifectively prevent the entrance of air and moisture. At the saine time the sash and frame can be assembled readily lbefore the central strip 13 is put in place and all of the parts then retained in working relation by securing the filling stripl 13 to the closing strip 8, 9.

. The usual chains, not shown, attached at one end to the weights 11, and passing over the usual pulleys at the top of the frame. pass down within the chain pockets 15 formed by the projecting portion of the jamb and within the plane of the Jface ofthe jamb and are secured within the same to the sash flanges.

It will be understood that various changes in details of construction can be made to suit difl'erent conditions of use and that, except as pointed out in the claims, the invention is not restricted to the particular construction shown and described herein.

I claim as my invention: y,

1. In a window, the combination of a hollow metal jamb having its opposite edge portions bent inwardly and in parallelism with the face, a closing strip having its edlge portions secured to the edge portions of t e jamb and havin a projecting middle portion, whereby a c ain pocket is formed with the edge portion of the jamb and within the plane of the face of Ithe jamb, and a sash having a ange entered in Ithe chain pocket and having a rounded offset to co-operate with the wall of the pocket. v

2. In a window, the combination of a hola jainb, and. having a projecting middle porlow metal jamb having its opposite edge porand a filling strip secured to the projecting tions bent inwardly and in parallelism with middle 'portion of the closing'strip to form 10 the face, a closing strip having its edge porchannels in which the flanges of the sashes tions secured to the, ed e portions of the move with asliding fit.

.In testimony whereof I hereunto aix my tion whereby chain pockets are formed with signature.

the edge portions of the weight box, sashes having flanges entered in the chain pockets, JACOB vWASSERBERGER.
