, To all whom it may concern."

citizen of the United States, residing at Chicago, in the county ofCook andiState' of Illinois, have invented certain new and use ful Improvementsin Metal Casement lVi'n-j dows, of which the following isa spec1fication;

The principal object of the invention isto provide a metal casement window wherein themain structural components of the fabrication constitute metal 'bars of standard shape. y

The window of the invention is particularly, characterized by an attractive appearance'which is equally suited forresiden-tial or commercial installations; a light but durable construction which is in conformity or small quantity production owing to the availability of thestandard 'bars and the simple formative operations involved in cutting, fitting, and joining the'b-ars. 1

Other objects and advantages which are not specifically referred to in this disclosure will be appreciated upon a full comprehen sion of the construction of the window and the arrangement therein of the standard bars.

For the purpose of exemplification, a pre ferred embodime'nt'of the inventionis p resented in the accompanying "drawingand in' the following detailed description. .Inas much, however, as other'slightly modified structural embodiments would also come within the purview of the invention," the particular embodiment heregp-resented not tobe considered as: limiting the spirit of-th'e' invention shortof its intendedscope as de-1 fined by the appended claims;

In'the drawing-- Fig. 1: is a front elevation of a double casement window which is constructed in accordance with the invention;

Fig. 2 is a horizontal section .on' 22ofFig.1; a I

Fig. 3 is a vertical section on the line 3-3 of Fig. 1; and

.Figs. 4 and 5' are fragmentary horizontal sections taken respectively through the abutthe 11in;

ting stiles and through one side stile. and jamb of'a metal. casement window wherein' are embodiedispeci'almetalbars which have standard metal bars of the invention.

It willbepobserved in the, drawing that v compriseftwo standard metal angle bars 13 I i 13 which. are s01 positioned in oppositely lapped relation as to present an outwardly extending'flangefil l in the front plane of the frame and an inwardly'e'xtending flange 15 in the rear plane of the frame. The contacting side portions of theloars'are welded at 16 to each other, and the end'portions of the bars are welded at 17 to the end portions of the bars of'each adjoining side of'the frame. y,

The

sash portions

11 and 12 are fabrica tions wherein the abutting "stiles severally" comprise a standard metal channel bar 18 the window includes a frame 10 and two" which is ,so positioned as repr sent outv, wardly extending flanges 19 and 20 in the. w

front and rear planes ofthesa'sh'portions and wherein the rails and thesidestiles severally comprise a standard metal angle bari21 Which'i'sso positioned as: to present; an outwardly extending flange in the front plan'eofthe sash'portions and arearw'ardly extending fiange23 perpendicular to the with a strip 25 which laps against the front face of the corresponding flange of the sash portion 11. The end portions of'the bars of each sash portion are welded at26 to each other. The muntins ofeach sashportion comprise standard ,metal flloars' 27 and the glazing, supports along the sides front plane ofthe sash portions at the inner" margin of the outwardly extending flange T 22. The front outwardlyeirtending'flangei of eachzsash portion in opposition to the muntins comprise standard metal angle bars 28.

Vl henthe two-sash portions are made to assume the closed-position illustrated, the flanges 19 and 20 of one sash portion abut against the corresponding flanges of the other sash portion, the flanges 22 of the two sash portions lap snugly against the flanges 14.;of theframe, and theflanges 21 of the two sashjportions abut snugly against the flanges 12,,of theframe; thereby providing adoubleline of contact and a resulting air pocket between the two sash portions and between each sash portion and the frame.

TheJgeneral mounting arrangement of the frame and the sash portions consistsin conneetingtheabutting stiles of the sash portions tov each other .by means of hinges 29 at therear face of. the sash portions and in pivotally mounting the spaced side stiles of the. sash. .portions to. vertically extending fixturesBO by'means of hin es 81, which fixtures are in turn mounted I01 horizontal sliding movement in the frame toward and away .from.;the; jambs. of the same.- As previously stated, such general niountin arrangement is covered-in my copending application,.but. an improved structural feature ofthe arrangement which is peculiarly adaptedto the. present. window construction consists in the, provision, at each of the hinges 31, ofa shallow notch 32 inrthe. outer margin :of, the flange- 22, through which notch the hinge leaf which-engages with'the, fixture passesrearwardly, wherebyto provide by such disposition of the hinge leaf, an unbroleencontour for. each sash portion and a Weather-proof closure at each hinge.

It will be.appreciated from the foregoing description that the, window of the invention is. susceptible: of a wide range of use-and may:be..pr0du'cedin any desired quantity ata. very low cost, since-the metal bars used iii-the fabrication .are always obtainable,

and ,no special skill is required inrcutting, fitting and joi'ning the bars.

In.Figs.. 4: and 5 is illustrated awindow which,.lunlike. the window of the. invention, embodies, special metal bars in-its construction. The over-all. sectional configurations of the; specialabars correspond however to those of the-standard bars embodied inthc present, invention.
