' .METAL WINDOW.

Application filed November 3, 1927. Serial No. 230,755.

This invention relates to the construction of metal window frames and has for its general objects to facilitate the manufacture of such window frames, and the assembling of the same and the window sashes, either in the factory oron the job, to increase the eliiciency of such Windows in excluding air, to provide for such disposition of .the pulley chains by which the sashes are counter-balanced, that they shall not be conspicuous and shall not be liable to contact with draperies, and to strengthen such windowframes so they will better resist distortion or breakage in the rough handling to which they are sometimes subjected in transportation and in erection on the job. These and other purposes are fulfilled b features of construction to be described ereinafter, with reference to the accompanying drawings in which they are illustrated in a convenient practical form and in which:

Figure 1 is a view in elevation of a window frame which embodies the several features of the invention, showing one of the jambs, a portion of the head, a portion of the sill,

and portions of the two sashes, the jamb and the sashes being broken out to save space, and portions of the jamb being also broken out and shown in section to illustrate details r of construction.

Figure 2 is a view in sectional elevation on the plane indicated by the broken line 22 of Figure 1.

Figure 3 is a detail view of a portion of the 5 head of the frame and jamb, seen from above,

with the cap of the head removed, illustrating particularly the relation of the sash pulleys and pulley housing to the head and jamb.

Figure 4 is a detail view in horizontal section on the plane indicated by the broken line 4.4 of Figure 1. I

Figure 5 is a detail view in elevation of the interposed section of the pulley stile.

Figure 6 is a View of the interposed section of the pulley stile in section on the plane "indicated by the broken line 66 of Figure 5.

Figure 7 is a det ail view in section onthe.

plane indicated by the broken line 7-7 of Figure 2, illustrating particularly the features of construction involved in the connection of each amb to the sill.

Figures 8, 9 and 10 are respectively perspective' views of the reinforcing plates at the top, mid-section and bottom of the jamb, 65 on a smaller scale.

Figures 11, 12 and 13 are respectively perspective views, also on a smaller scale, of the upper, middle and lower portions of the pulley stile, the upper and lower portions being .madeof a single sheet of metal, formed to suit the window opening it the wall and to receive within it the counter-balance weights, not shown, for the upper and lower sashes as shown clearly in Figure 4. The edge portions of the sheet of metal which for-ms the jamb are bent toward each other and again 8 toward the back of the jamb, to form jamb members a and (1 the edges being again bent toward each other, in a plane transverse to the plane of the window, to form flanges, as at a and a which are spaced apart throughout the vertical height of the frame. The jamb thus formed is stiffened and strengthened and its edge portions maintained in proper spaced relation by three heavy metal reinforcing plats b, 0 and d, shown respectively inFig-',

' ures 8, 9 and 10, at the top, mid-section and bottom. Each of these reinforcing plates is a on-the inside, thus maintaining the edge portions ofthe jamb against spreading and against compression. The reinforcing plate b is formed at its upper edge with tongues .b, b and b for connection with the head of i the sill of the frame.

The pulley stile is formedin three sections e, f and g shown respectively in Figures 11, 12 and 13, each section being formed to fit between themembers a and a of the jamb and thereby prevent displacement of the edge portions of the jamb members toward each other. It is desirable,,in order to maintain exact parallelism of the j amb members, that the opposite edges of each pulley stile portion shall be exactly parallel, andas a matter of convenience in manufacture such exact parallelism of the edges of the pulley stile members can best be obtained by turnin up the edges as shown at g". Each pulley stile memher is bent to form three projecting vertical sponding flange of the lower sas thus 'conrails e ,.e 6 f f f and g g 9 These rails form, between themselves and with the portions a and a of the jamb, the grooves which receive the flanges of the upper and lower sashes z' and is, as indicated clearly in Figure 4;, and the counter-balance"chains,

' one of which is shown at Z in Figures 1 and 2,

Being received in these channels or grooves the counter-balance chains are less conspicuous than they would be if the pulley stile was not grooved and they are not liable to contact with draperies. It will be observed that the vertical ribs'g and g of the lower pulley stile member are wider than the ribs 6 e", f and f? of the upper and mid members of the pulley stile, whereby the channel or groove below the meeting rails of the two sashes is just wide enough to receive freel the corretributing to the exclusion of air, while the wider channels or grooves formed by the nar-. rower rails e and e of the upper pulley stile member and the mid-section member are wide 1 enough to receive properly the chains Z.

The upper pulley stile member 6 is secured at its lower end to the reinforcing plate 0 by a screw e which engages at its upper edge, as at c the tenon of the middle reinforcing plate 0, and in order that this upper pulley stile portion 0 may be removed and replaced when necessary, without requiring the removal or replacement of a screw near the head of the window frame, this pulley stile member is formed at the upper end of the rail c with tongues e and e, as shown in Figure 11, to

enter slots formed in the soflit of the frame head as hereinafter explained.

The middle pulley stile member I is secured to the middle reinforcing plate 0 by a screw f? which passes through a hole f inthe middle rail) and is threaded into a hole 0 shown in Figure 9, in the tenon of the reinforcing plate 0.

Thelower pulley stile portion 9 is secured to the middle reinforcing plate 0 by a screw g which passes through a hole in the pulley stile portion and is threaded into a hole 0 in the tenon a of the middle reinforcing plate near its lower end. Another screw 9 passes through a hole in the middle rail 9 near its lower end, and is threaded into a holed in the reinforcing plate d,

The lower end of the lower pulley stile member is formed to fit against the sill.

To afford the proper contact surface of the sashes to prevent the passage of air up or down the grooves of the pulley stile and jamb around the flanges of the sashes, at the ends of the meeting rails, the interposed or middle section 7 of the pulley stile has secured to each of its rails 7, f and 7, by tongues 71. and h, which respectively enter slots in the pulley stile member, as indicated at f in Figure 12, and lap the end of the pulley stile member, a cap it, which forms a socket for the reception of rubbing pads h of felt, thus affording a felt bearing for both flanges of each sash and preventing the passage of air.

The soflit m of the frame head m is grooved as at m to receive the flanges across the top of the uper sash z, and within the head, extending from the inner face 'to the outer face, is a heavy metal reinforcing plate n which also forms the base of the housing which supports the sash pulleys 0 over which pass the counterbalance chains Z. The tongues 6 b and b of the upper reinforcing plate I; pass up through slots at m, m and m in the soflit m and through slots at n n and n in the reinforcing plate nand are bent over upon the reinforcing plate, thereby securing the reinforcing plate n rigidly to the frame head. A tongue (1 of the jamb is also passed up through the slot m and is bent over in a direction opposite to that of the tongue b The jamb is also formed with tongues a and a" which are passed up through slots m and m in the inwardly turned edge portion of the soflit m and are bent over toward each other. The j amb' is also formed at its outer face with a tongue a which is bent over upon the edge of an extended tongue m of the soflit. At its inner face the soflit is also formed with an extended tongue m", the upper edge of which is bent over upon itself as at m and is cut out to form two shoulders m and m. The

inner wall of the jamb is bent over upon the jamb is ri 'dly secured to the frame head tov prevent ative displacementin a vertical difill rection, and it is also secured to the frame head to prevent relative displacement in a horizontal direction.

. The jamb is rigidly secured to the sill p in such manner as to prevent relative displacement in a vertical direction and also to prevent relative displacement in a horizontal direction by means generally similar to the means described above for connecting the jamb and the frame head. Theinside depending flange of the vsill is turned back upon itself as at p and the turned up portion is cut out to form shoulders 12 and p. The lower edge of the inside wall a of the'jamb is lapped over the lower edge of the depending flange p of the sill and is formed with a tongue a, which is bent inwardly between the'shoulders p and 7), so that relative displacement of the jamb and the sill in a horizontal direction is prevented, while at the same time relative displacement in a vertical direction is also prevented.

To make it possible to attach and detach the counter-balance chain to and from the sash readily, there is secured to the upper corner of the sash bysome suitable means, such as spot welding, a hook q to be engaged by a link of the chain. It thus becomes pos sible to attach or detach the chain without removing any part of the frame and without removing the sash from the frame.

The tongues e and e of the upper pulley stile portionare passed up through slots or an L-shaped slot at m in the soflit of the head but are not turned over. Thereby it is possible to slip the upper pulley stile portion into place and secure it in place by the single screw 6 It will be observed that only four screws are required to hold the entire pulley stile in place.

It will be understood that not all of the herein described features of the improvements are necessarily embodied in one-structure but can he used independently of each other if conditions so require and that various modifications in detail of construction and arrangement can be made without departing from the spirit of the invention except so far as such detail may be made the subject of some of the following claims.
