1 Claim. (Cl. 189-43) upper sash is generally the outer sash.

The principal objects of the invention will be better understood if it is first recalled that in previous metal windows of the double hung type it has been customary to manufacture the frame member which fits the window opening as a metal extrusion, which extrusion has been provided with sash-retaining flanges at each side and also, as a general rule, with an interior midstrip or bead which fits between the sashes and is known as the parting strip. A construction of the kind just described makes it necessary to insert the window sashes edgewise into the frames either from the top or the bottom of the frame because the sash-retaining flanges and the interior parting bead make it impossible for the sash to be inserted into the frame member from one face or the other across the sashretaining flanges and the parting strip. As a result, assembly and installation of all-metal windows of this type have been awkward, troublesome and expensive.

The present invention provides an all-metal window structure which avoids the difficulties and complications above referred to and at the same time simplifies manufacturing procedures and reduces the cost not only of manufacture but also of assembly and installation on the job.

My invention also provides a structure which marked- 1y improves the weather-tightness of double hung windows and renders them more easily operated, i.e., opened and closed in service.

How the foregoing objects, together with such other objects as may appear hereinafter or are incident to my invention, are attained will now be described in detail in connection with the accompanying drawing, wherein:

FIGURE 1 is a face view of an assembled window of the double hung type, the view being taken from the inside looking out;

FIGURE 2 is a perspective view showing the sashreceiving strip of my invention with a pair of double hung sash members inserted therein and illustrating the manner in which the sash-receiving strip and the double hung sashes are inserted as a unit into the metal frame member; and

FIGURE 3 is an isometric projection on a greatly enlarged scale showing the frame member, the sash-receiving strip and a corner of the upper sash in horizontal section and showing the adjacent corners of the two sashes in vertical section.

In the drawings I have shown vertical metal frame members MP each of which has an outer face 4 adapted to engage the jamb of the window opening into which the frame is to be fitted. Each frame member is also provided with a flat inner face 5 adapted to engage the back fiat face or outer surface 6 of a sash-retaining strip 7, which fiat outer face is adapted to abut againstthe flat inner face 5 of the metal frame member. When assembled the sash-retaining strip may be secured in any desired manner as by a series of countersunk screws 8 which pass United States Patent 0 3,17%,215 Patented Apr, 20, 1965 through the strip and enter the adjacent frame member.

Along each edge the frame members, preferably, are provided with outwardly projecting flanges 9 and 10 for cooperation with the wall (not shown) into which the window is fitted.

The flat inner face of the frame members is provided with a sash-retaining flange 11 alongone edge only, preferably the edge which is at the outside of the window. This flange 11 projects toward the center of the window opening and acts as an abutment for the sash assembly now to be described.

. Each sash-retaining strip 7, on its inner side, is provided with a sash-retaining flange 12 along each edge thereof and with a parallel midrib 13 which forms a parting head or strip between the sashes 14. As best seen in FIGURE 3, theflanges 12 and the parting strip 13 are formed by suitably bending the metal of the sash-retaining strip 7, the sash-embracing flanges 12 being relatively shallow while the midrib or parting strip 13extends inwardly toward the center of the window opening to a sash-retaining strip to form therewith a vertically dis-' posed recess 16 on each side of the central rib 13, one of which recesses faces the upper sash and the other the lower sash. Along the outer edge of each midrib 13 I provide a re-entrant rib 17 which is arranged in direct opposition to the midrib 13.

Within each troughlike recess 16 I provide a vertically extending channel member 18 having its base against the adjacent sash and its legs extending toward the midrib. The end of each leg is provided with a footlike motionlimiting flange 19.

At a plurality of points vertically of the midrib 1 I provide flat horizontally arranged slots or apertures in which I mount a series of substantially V-shaped springs 20, the legs of which press against the adjacent faces of the base portion of the channels 18, as clearly shown in FIGURE 3.

The sashes 14 are loosely embraced by the pairs of ribs 12 and 13. .Sufficient pressure is exerted by the springs 20 to cause the channels 13 to hold the sashes in any desired position of vertical adjustment. In effect, therefore, the channels 18 and the springs 20, of which latter there may bea series vertically of the window, constitute not only a sash balance or holding means but also a very adequate Weatherstripping.

In assembling the sash-retaining member or strip 7, the

channels 18 and the sashes 14, it will be understood that the sash strip 7 and the channels 13 are slid into place relative to one another from either the top or the bottom of the frame before the completed unit with the sashes in position is introduced by lateral or sidewise movement into the frame member across that edge of the frame member which has no sash-retaining flange. In other words, my improvements make it possible to assemble the sash-retaining or receiving strip 7, the channels 18 with the springs 29 and the sashes 14 as a unit which can be simply, easily and expeditiously inserted into the frame member after the latter has been set in the window opening and, furthermore, that this can be done from the inside, namely, the side along which the frame member has no sash-retaining flange so that the assemblage or unit can be moved laterally into the frame as indicated in FIG- URE 2. It should be noted that in FIGURE 2 the bottom end of the unit is first entered into the frame after as a matter of convenience in manipulation and does not in any way imply that the unit is introduced from the top or the bottom of the frame because this latter is not necessary with my improvements. The unit can be held in the hands and bodily moved into its final position without first being tipped as shown in FIGURE 2- the tipping technique being suggested merely for the sake of avoiding holding the entire weight of the unit in the hands as it is being introduced into the frame. After the unit is inserted and secured in place a vertical finishing moulding strip 21 may be applied and this can be held in place in any desired manner.

I claim:
