To all whom it may, concern:

Be it known that I, 'ALFRED H. NEWrHER a citizen of the United States, and resident 4of Chicago, county of Cook, and Sta-te of' Illinois, have inventedr certa'in'new and useful Im rovements 111 Window-Sash, i.

drawings, forming apart thereof.' i

The invention relates to means for securing glass Within a sash', and more particu'- larly -in connection with a .sash4 formed of The-object of the :invention is-to provide for tlie'conv'enient entry-of the glass into the sash, and for securely yet removably holding` it inplace.

The. inventionis illustrated inthe accom# penying drawings, in Wliicli- 'Figure 1 is a detail face elevation of th improved4 sash Fig. 2 is a vertical section onV the line 2 2 of Fig. 1;'Fg. 3 is a detail section on the 'line 3-3 of Figi. 1; Fig. 4 is' Fig. 5 is'adetail of e' key for locking such "strip inl place; Figa, 6 is a" detail front elevation, partly in'sectiomyshowing .a modifiedform of construction; Fig'j. 7 is asectional View o n vthe line -7-7 of Fig, tg'andjFigf. 8- isn sectional View on the line 8 8 of'Fi'g 6,.

"strip, hereinafter described, 'a'iidthelfkey member for.loekiiig this-strip in place.; I To thisend tlii'erplcte v1'21 is curved inwardly from'tli'e upper` edge 'off the bar 1() to form a beadV 20, and. bent dow'mvardly to form n' shoulder217gainst 'which .the face of the glass may 4nest., 4thence inwardly toform' 'a seat 22jfor the glass, thence downwardly ,asi shown "at '23, and recurved :upon itsel as- .above the. rib 29 thereof.

oe'tfplece, prefshown et' 24, forming a, recessl and nv shoulder 25 against-Which the upper Amargin of' the plate may Vbear and togwhich it may be soldered. Continuing upwardly vthe inarginal portion of'the .p late`14 is bowed outwardly, forming a 'cove 26, the edge of the plate standing in 'toward the glessbut being spaced apart therefrom.

The glsissreteinin strip 27 is of elastic sheet meta-1, preferaly spring brass. Adjacent its lower edge it is bentinward, as shown' at 28,- to form a 'foot adapted to fit Within the recess'between the. portions'23 and of 'the late 1 4 and rest'upon the 4bottom 24s of this, chamber. 'A longitudinal outstanding rib '-29 rests upon the shoulder at the top of the section 25, entering the coye 26. The'up'per margin of the plate 27 lnward, for1ning e depending flange 30 for bearin" against 'the glass.'

The ey meinber'l is e stri 3 of met-ala J- proxiniately dial-f round, l l

'The key 31 is-lso longitudinally grooi'ed in parte 241m 25' being 'aperl tured in line' with these channels; The. inner Inasse'mbling' the 'pa-rte, the freine of the 'l sash is 'r's't constructed entire. T he reteining strip 27 and .key 31 "arefinserted in the bottoinzsashbar, and 'the lower edge of the glass t!) ie then forced into pince, preferably ii biinliii v 44 of rubber being ii'fit applied to it. Tile rctnning strip 35 is now inserted in connection with the top bur, and the key :i7 is forced in longitinliiinlly through one of Ilic channels 38, B9. The length of this key is such thiit its ends terminate at the inner edges of thc channels 42, 43. The retaining strips 34, one at either side, are now inserted und the keys 36 are for ed in endwisc from above through t- he channels 42, 43. 'llicse kcvs nrefernbly are of such length us to extend to the upper ninrgin of the top bnr 11. The glass is now securely held in pliicc by spring pressure of the retaining plates supplemented by the spring ressure of the cored portions 26 of the p etes of which the several rails or bars are formed. The glass cnn, of course, be removed by reversing the opera-tions performed in assembling.

[n Figs. (i, 'i' und 8, the sume general construction is followed :is in Figs. 1 to 5. In lien, however, of the coved portions 26, the upper margin of the plate 14 and corresponding portions of the plates of which the side und top bars are formed, are offset outwardly, ns shown at 45, and continued upwardly in the same pla-ne as the plate 15 of the bottom bar und corresponding portions of the side and top hairs, its upper edge being bent inwardly, as shown at 46. The keys 47, 48 and 49 are of less thickness, and the side and top bars, instead of channeled, are apertured, as shown at 50 and 51, to permit the entry of the top and side keys. As illustrated at 52, the outer side bars may be longgitudinnllyT channeled.

I claim as my invention- 1. In a window sash, in combination, a har having n longitudinal shouldered seat for n plate of Glass, an instanding flange facing thc shoulder, a resilient plate adapted to be interposed between the flange and a plate of glass occupying the seat, and u key interposed between the flange and the resilient plate.

2. In a window sash, in combination, u bar formed of sheet metal wrought to tubular form, the inner margin of the bar having a shouldered seat for a plate of glass :ind a channel at the opposite side of the scat from the shoulder, a. flange rejecting from the outer well of the channe and having its margin directed inward, a resilient retaining strip fitted within the channel and projecting beyond the (lun c, sind it kc rod inter ed between the ci ge of the ange und the retaining strip. I

3. In u window susi, in combination, u bnr formed of u sheet of nietiil wrou lit to tubular form, the inner margin of tie bin' having a shouldered seat for ii plate of glass and a channel at the o postte side of the sent from the shoulder a ange rejecting from the outer well of t e channeland having its margin directed inward, c resilient retaining stripeftted within the channel und 1rojecting yond the ilu e, and n key r interposed between the ridge of the iiange and the retaining strip und having a longitudinal groove for en agement by the flange. l

4. In it win ow sash, in combination, u bor formed of sheet metal wrought to tubular form, the inner margin of the bar having it shouldered seat for a plate of glass und a channel at the opposite side of the seat from the shoulder, a flange rojecting from the outer wall of the channeiaiid having its margin directed inward, a resilient retaining stri fitted within the channel and projecting yond the flange, and a key rod interposed between the edge of the flange and the retainin strip au having its inner face longitu inally grooved.

5. In a window sash, in combination, a bar formed of sheet metal wrou ht to tubulnr form, the inner margin of te bar having a shouldered seat for a plate of glass and a channel at the opposite side of the sent from the shoulder, a flange projecting from the outer wall of the channel and having its margin directed inward, a resilient retaining stri tted Within the channel and (projecting yond the flange, and a key ro interposed between the edge of the flange and the retaining strip and having its inner and outer faces longitudinally grooved- 6. In a Window sash, in combination, to J, bottom and side bars each hnvi U a shou dered seat for a. plate of glass, a ange facing and having its edge directed toward the seat, resilient retaining plates inside the iianges, and key rods fitting between the anges and the retaining plates, certain of the sash bars transversely recessed to permit the entry o the key rods.
