GEORGE H. FORSYTH. OF CHICAfGO, ILLINOXS.

' nm'ranarrnnosi".

To all whom it may concern:

' Be it' known that l, GEORGE H. FonsY'rH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, vhave invented certain new and useful 4lm rovements in Metal. Windows, of which the following is a specification.

My invention has for its general object to provide an improved metal -window construction wherein the sash may be adapted to variations in width or height of the casing, while at the same time preserving the proper engagement with the guides oi the casing. l show constructions wherein thls object may be accomplished through the provision of cooperating surfaces on the sash and guide inclined to the plane of the sash, and also by means of an adjustable element of the sash, the latter also permitting the edgewise insertion of the glass within the sash.

My invention, in an approved form, is illustrated in the accompanying drawings, Wherein,-

Figure 1 is an elevational view of a window sash showing one of the stiles thereof removed to facilitate the edgewise insertion of the glass into the sash and illustrating the adjustability of one of the sash members. Fig. 2 is a top plan view, partly broken out and in section; Fig. 3 is a vertical sectional view on the line 3 3 of Fig. 1; Fig. 4 is a bottom plan view, partly broken out, of Fig. 1; Fig. 5 is a detail horizontal sectional view illustrating the means for adjustably uniting the detachable sash member tothe sash frame; Fig. 6 is a detail elevational view of the lower right hand corner of the sash showing the detachable stile in the sash frame; Fig. 7 is a similar view of the upper right hand corner of the sash; Figs. 8 and 9 are detail cross-sectional views, on an enlarged scale, on the lines 8-8 and 9 9, res ectively, oi Fig. 7; and Figs. 10 to 19, inc usive are detail cross-sectional views illustrating the various forms ol inclined surface engagement between the sash and its casing guides.

In the drawings, 20 designates as an entiret the bars and 21 the stiles of the. sash. In t e forms herein shown, these members are hollow, being made of suitably bent strips of sheet metal. As shown at the upper end of Fig. 3 the two parallel face members of the stile are inwardly offset at 22 to erlnit the olset portions to be overlapped by the ends of the parallel members oi the bar 20 Speeication of Letlici's Patent.. l

and riveted thereto, presentin Hush surlaces on both sides.- @ne of tie stiles 21 (that shown at the right in Fig. 1') is removably and adjustably secured to the top and bottom bars by the following means. The up er and lower offset portions 22 of said stie are s rovided with

holes

23 and 24, respective y, occu in varyin transverse positions in the st' dr sagid holes icing adapted to register with holes 25 and 26 formed through the adjacent ends of the upper and lower bars, respectively, and receive screws or bolts '27 and 28 for uniting said members.y An auxiliary means for adjustably securing the removable stile 21 may consist of a pair of spring tongues 29 (Fi 5) secured to the innervfaces of the paralle members of either 'o r both of the bars, said ton ues being inwardly offset to provide for t e insertion of the oHset end portions 22 ofthe stile between the same and the inner faces of the bars, and having outwardly turned lips 29 adapted to enter in one vertical series of a number of correspondingly sha ed slots 30 formed through the offset portions 22 ci the stile. This auxiliary fastening means may be applied to either or both of the bars and either or both ends of the stile, as desired.

'31 designates the glass, heldin place within the sash by strips 32, preferably also ol` -sheet metal and bent to the cross-sectional form indicated in Figs. 8 and 9, said strips having a hollow ortion 32a extending within the hollow sti es (for which purpose said stiles are bent to provide a rentrant portion 21, Figs. 8 and 9) and inwardly inclined spring lips 32b clamping the glass. ln order to insure a closed joint of the glass-holding strips at the corners formed by the removable stile, l miter the ends of the strip 32 carried by the removable stile, which provides an opening for the (passage therethrough of the adjacenten s of the horizontal strips carried by the upper and lower bars, the Initered ends of the vertical strip 82 providing a closed joint with the inclined sides of the removable strips in all positions of adjustment, as more clearly shown in the cross-sectional view, Fig.l9.

From the foregoi that in assembling t e parts of vthe sash, before the removable stile 21 is applied the glass 31 can be inserted edgewise into position, Fig. A1 showing said glass inserted through the open edge of the sash and nearly in fully entered position therein. The reit will be observed,

movable stile 21 is then applied, the upper the casing as by a screw 40 having a beveled and lower offset ends enterlng inside the adjacent ends of the bars and, in the case of the upper end as herein shown, fitting between the latter and l the spring tongues 29, as shown more. particularly 1n Figs. 5 and 7. In this operatlon the lips 29a enter one of the series of slots 30, according to the intended width over all of the sash, in which position the hole 25 registers with one of the holes 23, the holes 26 in the lower bar similarly registering with a pair of holes 24, the exposed edOe of the glass being received to a greater or rless depth between the strips 32, as clearly shown in lgs. 8 and 9. The insertion of the screws 27 then effects the secure union of the parts, preventing accidental displacement of the removable stile.

At the lower end of the stiles I have shown the latter connected to the adjacent ends of the lower bar (see Fig. 3) by means of cleats 33 riveted to the inner sides of the parallel face members of said bar and stiles this last described connection being optional with the construction shown at the upper end of the stile for uniting the same parts.

It will be observed that the sash described and shown has merely stiles which are transversely yieldable or elastic, for which purpose the solid transverse portion of the upper bar is cut away where it overlies the upper ends of the stiles, as shown at 34 in Fig. 2, and similarly the solid transverse member of the lower bar may be cut away at the ends to form V-shaped openings 35, the gussets thus formed (for the sake of giving a more nearly closed and finished appearance) being severed from the intermediate portion of the transverse member, as indicated at 35a, this construction permitting transverse yielding or elasticity at the lower ends of the Stiles.

l'In Figs. 1() to 1,9, inclusive, I have illustrated a variety of forms which the coperating stiles and guides of the casing may assume, all with the general purpose of permitting a certain extent of bodily widthwise adjustment of the sash relatively to the opening while maintaining a proper it of the stiles in or upon theiiwguides. It will be observed as a characteristic common to all of these forms that the sash -member and guide have cooperating surfaces that are inclined or oblique to the plane of the sash, this construction, where the sash member is transversely yieldable orelastic, ermitting widthwise variation of the sash re atively to the opening without destroying the proper engagement of the sash and guide. In all of the figures except Fig. 19, 36 may be assumed to represent in cross-section a portion of the casing having a vertical uidegroove 37. In Fig. 10 I bend inward y the projecting portion of one of the parallel face members of the stile, as shown at 38, said bent margin contacting a strip 39 secured to In Fig. 12 both of the parallel face members of the stile are outwardly bent mar inally as shown at 41, and the strip 42 of iig. 11 is replaced by a strip 43 similar thereto except that it has an o lique inner bearing surface 43'$1 engaging one of said bent margins 41.

In Fig. 13 the groove 37 has both its side walls inclined in the same direction (herein shown as parallel), as indicated at 44; and the marginal portions of the face members of the stile are similarly bent or inclined to iit said surface. f

In Fig. 14 the integral side wall of the groove is inclined inwardly relatively to the sash from its outer edge, as indicated at 45, the coperating margin of the stile'being similarly bent to engage the same; while the inwardly turned margin of the other face member of the stile engages a wear strip 46 secured in place as by a screw or brad 47 and having a wear face 48 similarly but oppositely inclined to the wall 45. Said wearstrip 46 is backed by a finishing strip 49 extending flush with the inner transverse wall of the casing opening.

Fig. 15 shows a stile having one straight face and its other face outwardly bent marginally to en age a correspondingly inclined surface 50a o a removable strip 50.

Fig. 16 shows a casing provided with a substantially V-shaped groove, and the marginal portions of both face members of the stile inwardly turned to engage the' inclined walls 51 of said V-groove.

In Fig. 17 I have shown the bottomwall of the groove provided with a central projecting rib 52 having oppositely inclined surfaces 52a that are engaged by inwardly and backwardly bent marginal portions 53 of the arallel face members of the stile, the latter aving also an outside bearing against the parallel side walls of the groove.

Fig. 18 shows one side wall of the groove formed by a removable strip 54, the inner face of said strip having a straight portion 54a engaging one of the parallel face members of the stile, and also an inclined convex portion 54b which is adapted to be engaged y an inwardly turned'marginal ortion 55 of the other face member of the sti e.

The principle of the oblique or inclined transversely adjustable bearino' between the sash and the guide, as exempIiiied in Figs. 10 to 18, inclusive, is capable of being carried out in constructions wherein the acting guide,

classi instead of beinr formed as a groove, 4takes the form of a rib or projection embraced by the parallel face members of the stile. Such a construction is shown in Fig. 19, wherein 56 designates a guide rib triangular in crosssection secured to the wall 36 of the casing as by a screwl57, the o lposite inclined sides or" said strip being slida y engaged by inwardly bent inclined marginal portions 58 of the stile members. In the forms shown in Figs. 10 to 18, inclusive, wherein the sash guide consists of .a roove in the casing, the parallel face memers of the stile may possess a transverse elasticity normally tending to spread said members beyond the width of the groove; in which case said members, when engaged in the groove, are under a greater or less degree oi compression, thus insuring a dust-proof and rattle-proof iit. At the same time the.

provision of the inclined engaging surfaces combined with the elasticity of the sash member enables a given sash to fit and operate in window openings of somewhat vary ing widths. On the other hand, Where the sash member may not possess transverse elasticity, as when made solid, the same adaptability of the sash to window openings of somewhat varying widths is secured by the detachable stri s which may, after the sash has been intro uced, be applied so as to produce an o erative fit against that side of the sash whic they engage. In the case of the construction shown .in Fig. 14 the inner strip 46 may be adjusted within certain limits Without disturbing the position of the main confining strip 49.

The constructions hereinabove described may lend themselves to a still further advantage in respect to the manner of inserting the sash in the casing where the total width of the sash is less than the distance between the bottoms of the grooves by a distance equal to or greater than the depth of one of the grooves, in which case, by suliiciently expanding or contracting the stile on one side it may be inserted into one of the grooves until contacting the-bottom of the latter, which will allow the outer margin of the other stile to enter the mouth of its coperating groove, the sash being then moved widthwise of its groove. Such a construction is illustrated in Figs. 15 and 16.

I do not limit the invention to the particular forms and constructions shown and described, as the same may obviously be varied to a considerable extent without departing from the principle of the invention or sacrificing any of the advantages thereof. f Y
