I have4 devised my im roved sheet-metal sash for use more artic arly in thernodern t pe oi steel rai wa -cars, as bein es ey y' houpgh the more important features of my-improvemeilt are-adap`tableto window-sash gener y. l

The four rails of a square window-sash 12 like that shown in- Fig. 1, are hollow .and may be formed out of a continuous sheetthe-section for each rail and the ends bevele at their edgeortions to '.orm the interfit- Itingc'orners ov the sash,lsubstanta1 1yas depresent is a:

ads to the sash;-

scribedof the sash of m pending application,y Serial No. 546,883, ed March 2, 1910., Each Side sash-rail is given the configuration illustratedin Fig. 9 bybending a sec- "tion of the sheet-metal blank, referred to,

to produce the' inner vertical face 13, the 'lateral face 14, a vertical. outergface 15 curved convexly at 16 to form a crown-poration, a rectangular seat 17 for the windowpane 122, cushioned as hereinafter described, an outwardly-inclined vertical socket 18, and a vertical bead-seat 19. The meeting edges of 'each side-rail, as at 40, may be united by welding or brazing. The conguration of j the upper 'sash-rail," shown in Fig. 10, is produced by bending theY proper blank-section to ,producethe'inner face 13",'the topface 14 the outer .face 15', the crown-portion 16', window-panel seat 17', ,incllned socket 18 and bead-seat 19.` The bottom sash-rail, shown in FigJ-2, is produced by bending'the proper blank-section to 'produce the linner face 132, bottom 142, outer face 152 with upper crown-portion 162 and window-pane seat` 172, socket 182 and beadseat 192.A The socket 182 has key-openings formed transversely vand coincidentally through its walls,'fas shown,'the opening illustrated at '20 in Fig: 7 whichis the innermost one, being rovlded with lateral reycesses 20 diametrically opposite each other,

for vthe purpose hereinafter explained.

Trough-shaped cushions 21, preferably of softrubber covered with` canvas 22 to shield the rubber against'contact 4with metal, lit against the seats-17,17 and 172' provided' for them in the rails andlthese cushions,

which confine the window-pane'at its edge-l portions andserveto protect it against fracture. from vjar, shock and the like, are grooved, "as shown at 22', alongtheir seating-faces in molding them, for azpurpose y hereinafter explaine For releasably connin A in the sash, .thereby-to, a apt a broken pane to be readily. taken out and the sash-to be glazed without requiringlit to be removed rom the window-frame, ads are employed those illustrated being formed hollow outoii sheet-metal from suitable blanks. The two beads '23,.. 23, forthe side-rails of the sash and the bead. 24 "fori the top-rail are alike, while the bead- 25 for the lower sash-rail,

the window-pane though of "the same' configuration., 'as the.

fine the latter.

other beads, is provided in two similar longitudlnal sections, each formed out of a sheet-metal blank 26, ,like that represented'. in Fig. 8, having a notchv 27 in one end and a tongue 28 projecting from its opposite end and in alinement with a rectangular opening 29 in the blank at a corner-portion thereof. The blank for each bead 23 and 24 is like two of the blanks 26 formed as a continuous strip with notches 27 in its ends and omitting the tongue 28 and opening 29, so that themanner of forming each bead will be understood from the following description with reference to bending the blank of Fig. 8.

By suitably bending the sheet-metal strip along the dotted lines 30, 31, 32 and 33, the Hat base 35, the the flat back 37 o the bead are formed, and suitably bending the blank along the dotted line 34 forms the crown-portion 38 and the fiat .face 39 of the bead, vthe edge of which face may be united to that of the base 35 at 40 (Fig. 6) by welding or brazing.

A blank 26 is formed in the manner described into each section of the bead 25, and the tongues 28 on their meeting edges are each bent into the segmental shape illustra-ted in Fig. 4 to abut against each other and constitute a semi-circular keeper 41 for the purpose hereinafter explained. The beads are pivotally connected together at ears on their ends, like the ear shown at 42 in Fig. 6, Where the ends are caused to meet and interft by 'the notches 27 provided -in the blank-ends and conform to the corners of the sash-frame when thebeads are adjusted in place therein with their bases 35 against the seats 19, 19 and 192, respectively, their tongues in the sockets 18, 18 and 182, respectively, and their sides 37 bearing against t e adjacent sides of the cushions 21 to con- As will bey observed, the crown-shape of the beads causes them' -to conform to and round out the crown-portions of the sash-frame rails.

To fasten and tighten the beads in place, a. key 43 is employed (Fig. .2). It has a sl'ottcd screw-head 44 on oneend of a cyliindrical stem to adapt it to be turnedby a screw-driver, and it terminates at its o posite end in a comparatively thin crosscad 45.' This key is inserted through an opening 46' in the bottom sash-rail near the inner end of one of thetwo sections of the divided bead 25, and through alining openings' in the socket .182 (including the recessed opening 20) and a slot in the tongue 36 therein; 'and a 'slight turn of the key will vtake its Ahead 45 out of re 'stration with the recesses 20 (Fig. 7) an thus cause it to obstruct withdrawal of the key. The stem of the key carries, to turnjwith it, a 'hookshaped 'latch 47 'which extends into the bead 25 through, and works-in elongated slots 48 gutter-like tongue 36 and rail and base of the bead-section upon it; and on the key-stem is confined, between the hub of the latch and the adjacent wall of the socket 182, a spiral spring'49 tending to hold the key in place when turned to its described 'non-withdrawable position. By turning the key to that position the latch 47 enga es the keeper 4l, as shown in Fig. 4, the fgree end of the latch 'enteringy the opening 29, which is that shown in the blank 26; and thus the beads are locked in place, the sections of the bead 25 being tightened by the spring-action of the key ,against the adjacent' cushion 2l and compressing it,

thereby narrowing the groove 22 with the effect of mutually tightening the cushions and edges ofthe window-pane against each per and side beads to enable them to be removed, as for taking out of the sash a fractured window-pane and inserting a new one, which is then to be fastened in the sashframe by adjusting the beads in placesand .securing them with the key 43.

What I claim as new and desire to secure by Letters Patent isn l. In a window-sash, the combination of a frame comprising rails provided with window-pane seats, beads coperating with said seats to confine the pane, one-of said beads comprising longitudinal alining sections,l and key-operated means cooperating with a frame-rail and said sections to releasably lock the sections'together. 2. In a window-sash, the combination of a frame comprising rails provided with Window-pane seats, beads coperating with said seats to conne the pane and pivotally connected end to end, one of said beads comprising lon itudinal alining. sections, and key-operate means eoperating with a frame-rail and said sections to releasably lock the sections together. 3. In a window-sash, the combination of a frame comprising rails provided with window-pane seats, trough-like cushions on said seats for confining a pane at its edges, said cushions being grooved along their seating faces, beads coperating with said cushions to confine them, and key-operated means cooperating with a .frame-rail and the bead thereon to releasably secure the beads in place 4. In a Window-sash, the combination of a i frame comprising rails provided with win-v dow-pane seats, trough-hke-cushions on' said seats for confining a pane at its edges, said cushions being groovedalong their seating edges, beads coperating with said cushions to confine them and flexibly connected at their ends, one of said beads ycomprising 13C longitudinal alining sections, and key-operated means coperating `with a frame-rail and said sect-ions thereonto releasably lock the sections together.

5. In a Window-sash, the combination of a frame comprising rails provided With window-pane seats and bead-seats With interposed sockets, beads removably fitting against said seats and having tongues extending into said sockets, one of said beads comprising longitudlnal alining sections with a keeper on their adjacent ends, a key Working -in the frame-rail provided with said bead-sections and passing through the socket and tongue in its path, said key having a head on its inner end, and a latch on the key extending into the adjacent beadsection to engage said keeper.

6. In a Window-sash, the combination of a frame comprising hollow rails of sheetlnetal provided with Window-pane seats and bead-seats with interposed sockets, hollow sheet-metal beads fitting against said seats and having tongues extending into said sockets, one of said beads comprising longitudinal alining sections with a keeper com.; prising cooperating parts on their adjacent ends, a spring-pressed'key Working in the frame-rail provided with said bead-sections j and passing through thesocket and tongue in its path, said key having a head on its inner end, and a latch on' the-key extending into the adjacent bead-sections said keeper.
