Dec. 8, 1942. M..B. SCHILLER METAL WINDOW SASH Filed Feb.l 26, 1940 Patented Dec. 8, 1942 Y METAL WINDOW sAsH Morgan B. Schiller, Sewickley, Pa., assignor to American Tubular Elevator Company, a corporation 'of Pennsylvania Application February 26, 1940', Serial No. 320,886

(Cl. 18S- 76) 2 Claims.

My invention relates to window structures, more particularly to window sashes, and consists in improvements and refinements in structure.

'I'he sash of the invention, Iproviding as the usual sash the immediate support for a glass window pane, is essentially constructed of metal. It is a sash in which the pane of glass may be readily assembled and marginally sea-led, and it is characteristic of the sash structure that no putty or other sealing material is exposed to View, or to the deteriorating inuences of the weather. My sash is of the slidingtype, adapted to be moved up `and down in its frame. It is of neat and pleasing appearance.

. In the accompanying drawing,

Eig. I is a fragmentary view of a window frame, showing in front elevation a sash of my invention mounted therein;

Fig. II is a fragmentary view, showing the structure to larger scale and in cross section, on the plane II-II, Fig. I;

Fig. III is a View `comparable with Fig. II; the window frame portion is deleted from the showing of Fig, III, and, whereas in Fig. II the sash is shown completely assembled, in Fig. III a certain sash element is illustrated `in course of` assem-bly;

Fig. IV is a fragmentary sectional view of the sash frame, on the plane IV-IV of Fig. II; and

Fig. V is a fragmentary sectional view, on the plane V-V of Fig. I.

Referring to the drawin'gthe sash l of the nvention is mounted for vertical adjustment in the` opening 2 of window frame 3. The window frame includes at each of the opposite vertical sides `or edges of the opening a thin flangel di; the two flanges 4 extend in common plane and provide guide-rails upon which the sash I is vertically slidable. The frame 3 will ordinarily include two slidable sashes, but inasmuch as my present invention is concerned primarily with the structure of the sash per se, the illustration of one of the sashes will herein suflice.

The sash lvconsists in a reactangular frame formed of four frame members a, b, c, and d, assembled end to end and united, say by welding. The frame members are formed of extruded or rolled sections of metal (preferably a metal of light Weight, such as aluminum) cut to proper length and united, as said. The detailed struotural shape of these metal frame members is of the essence of the invention.

Turning to Fig. Il, it will be understood that the frame members a, b and c are of H shape in cross section, the H lying on its side as viewed in Fig. II, with the two legs 5 and B of the H horizontal and the cross-'arm 'l vertical. The H- sectioned frame or sash portions extend (save for an exception later noted) throughout the peripheral extent of the rectangular frame. With such peripheral continuity of the structure held in mind, a simple description that deals primarily withthe legs of the H will suffice to give an understanding of the structural features of the i'nvention.

The portions of the two legs of the H on one side of the cross-arm '1 -the leg portions to which the reference numerals 5 and 6 are immediately applied-form a groove 8 that opens through the inner peripheral edge of the sash or frame. In the assembly of the four frame members the groove 8 is of uninterrupted circumferential' continuity, and yin this groove the pane G of glass is marginally engaged and secured in the sash. A packing P of putty or other packing 'compound is provided in the groove 8, to insure the desired hermetic sealing of the rim of the pane G in. the sashi On the opposite side of the ycross arm I of the H, the leg portions 5o', and 6a form a groove 9 that opens in the outer edge or `periphery of the yframe and extends in uninterrupted conti-` nuity throughout the continuous periphery of the three frame members a, b, and c. At the vertical sides of the sash, the guide-rails 0. are slidably engaged in the groove 9, and Iby virtue of such engagement the sash is secured in assembly with the main window frame 3. It may be noted that the frame 3 includes at the top of opening 2 a ilange 4B, identical with, and extending in common plane with the flanges that form the guiderails for the sash. When the sash is positioned at the top of the opening 2 in the frame, the' flange 40 enters the portion of groove 9 that ex tends in the sash frame member b, thereby insuring weather-tight conditions at `the top of the window structure as well as elsewhere. The walls of the groove 9 may be, as here shown, lined with felt 9U, to enhance the desired snug and weathertight engagement of the parts.

It is desirable that the sash shall engage the guide-rails 4 with friction which is such in effect and magnitude that, while not preventing the intended sliding adjustment of the sash, will serve to secure the sash in the position to which it has been adjusted in the frame. To such end, I advantageously provide in the portions of the groove 9, that are included in the opposite vertical sides of the sash, one or more leaf-springs Il (Fig. IV). These springs are secured in place in the groove, by means of teats l2, formed in the metal groove 8.

,body of the sash frame, say by an embossing or 5c, Ec, extending peripherally of the sash frame,

serve to secure the felt lining in place, and to insure nicety of engagement of the sash with the guide-rails 4. The inturned portions 5d and 6d provide in like manner a snug engagement of the legs of the H with the opposite faces of the marginally engaged glass pane G, and additionally serve to complete the protective enclosure of the packing P within the groove 8.

The groove 9 is not required in the lower horizontal limb d of the sash frame in this case, and thus in such limb the groove-forming leg portions 5a and 6a of H are omitted. The less specialized section of the lower frame or sash portion d is illustrated in Fig. V.

In order to permit the ready assembly of the pane of glass G in the sash, the leg portion 5 of the H is provided in the form of a separate element. Indeed, such leg portion 5 of the H represents in the rectangular sash frame fourremovable strips 50, one for each of the limbs a, b, c y

and d, and when these four strips are'assembled in the frame they meet end to end, as shown in Fig. I. The four strips 5i] are provided with means for eiecting their ready and secure assembly in the sash structure. Returning to a consideration which is engaged in a groove 5h formed in a rib f portion 5i integral with the rigid leg portion 6 of the H. Cooperating with the bead-and-groove engagement 5f, Eh, (in the securing of the detachable strips 5U in the sash assembly) is a tapered, sharp-edged rim 5m and this rib, located at the heel of the L, is engaged in a peripherally extending notch 5u formed in a peripheral ridge 5r on the rigid body portion of the frame of the sash.

The assembly of a glass pane G in the metal '.r

sash of this invention is a simple matter. The four strips 5l! are removed from the sash frame, and the pane is laid in place, with its marginal edge lying in the open or uncovered peripheral (See Fig. III.) Next, a packing P of putty is applied around the edges of the pane, and then the strips 50 are applied one by one and.

locked in assembly. (Note Fig. II.) y Fig. III illustrates in cross section one of the'strips in course of assembly. The flange portion 5e carried by the strip is inserted in the interval between the crossarm 1 of the H and the rib 5i, and then pressure is applied in the direction of the arrow. Under such pressure the strip moves downward (as viewed in Fig. III), and the tapering nether face of the rib 5m makes Contact with the proximal edge of the ridge 5r. As the strip is thus moved towards assembled position (Fig. II), the sliding engagement of the tapering nether face of rib 5m against the edge of ridge 5r exerts a wedging effect, such that the body of the strip shifts in left-to-right direction, Fig. III, and laterally As the strip reaches fully assembled position, theA bead 5f on the ange snaps into place in the groove 5h, and the sharp edge of rib 5m latches in the notch Em in the body of ridge 5r. With the parts in such positions of engagement the strip f is firmly secured in assembled position, as shown in Fig. II.

In such manner all four of the strips 50 are assembled and locked upon the edge of the pane or panel of glass.

I claim as my invention:

1. A Window sash comprisinga. rectangular frame including a peripherally extending recess that receives the rim of a panel secured in the frame, one of the peripherally extending recessforming walls of the frame comprising a removable strip of L-shape in Vcross section, with a rib at the toe of the L and a rib at the heel of the L, the body of the strip between such ribs being elastic, and the body of the' frame including two grooves severally receiving said ribs in yielding strip-securing engagement.

2. In a window sash comprising a rectangular frame including a peripherally extending recess that receives the rim of a pane of glass assembled in the frame, and means securing the pane in s uch assembled position; said means comprising doubly-flanged keeper strips of L-shape in cross section, each strip being assembled with one flange in engagement with the margin of the pane and the other flange yieldingly interlocked with the frame on two lines of engagement that are severally eective at the toe and at the heel of the L, the engagement at the heel of the L consisting in a -beveled rib on the keeper strip and a notch in the frame body that receives the rib, said beveled rib being adapted as the strip is pressed into assembled position to engage the body of the sash with wedging eiect, whereby the last-mentioned flange is stressed into yielding engagement with the frame body.
