lApplication filed March 2, 1910. Serial No. 546.5883.

To all whom it may concern:

Be it known that I,EDGAR M. MATTHEWS,

I a citizen of the United States, residing at Chicago, inthe county of Cook and State of Illinois, have .invented a new anduseful Improvement in WindoweSash, of which the following is a specification. The primary object of `myinvention is to provide a construction of window-sash whereby the pane of glass which' it is designed to hold may be readily introduced into and secured in it, and a broken pane may fbe. removed lfrom it, without requiring the sash to Ebe removed from the window.

While my invention may be used in win dow-sash generally, I Vhave devised it more especially for sheet-metal sash'and particularl)7 for use inthe windows-oi railway cars, whichis fthe form thereof illustrated in the accompanyin drawings, in which- Figure 1 s ows my improved sash by a view .in rontjelevation; Fig. 2 is an :enlarged section 4on'the irregular line 2 2, Fig. 7

Fig. 3 is labrolren plan view of the.y sheetmetal blank lirom which the' sash-trarne is formed; Fig. 4 l:is an enlarged broken perspective view -ofa section of one-of *the sash-A rails formed lout 'of the blank; Fig. 5 lis a.

similar view of a section :of one or the removable sheet-metal beadswhich cooperate. with the sash-rails' lfor holding' the pane in 2 place; Fig. 6 is an enlarged section cnil-inay 6 6, Fig. 1; Fig. 7 is an enlarged sectionI Online 7-7, Fig. 1; Fig. 8 4is a view in sec--f 'tional elevation of la headed 'clam ing-'block detail, and Fig. 9 is a *face view olthe same; Fig. 10 is a perspective View of la clampinglcam detail, and Fig. 11 is a view in side velevation of the bolt-'likekey for separablylfastening together the parte which clamplthe v pane 'in the lsash-tranne.

t-The blank l2 (Fig. 3) is a continuous 'sheet-'metal 'strip of generally-rectangular -cr'oss section with coincident V shaped notches, one pairof which is Vshown at 13 in its opposite edges, 'and the ends being simila-rly beveled. These notches ldene the blank-sections, all of which are alike for an equilateralk rectangular sashV such as that shown -in Fig. 1, but may otherwise vary in length. To vform the fourrails of a sash 14 the Vblank'sections are bent at their junctions between -the 'notches to extend at rightv 'angles -to 'each other and, preliminary there. 'to, are each 'bent along the brokenr lines veach lrecess is shown on the blank. Thus-the relativelyT wider and narrower sidesl `and 17 are bent along the lines 151 and 171 to extend parallel with each other and form of'the part 19 between the bending-lines the marginal face 20 (Fig. 7) or base of the rail. Each side 15, which forms the outer face `21 of the respective rail, is then curved along .the line.

152 to form the crown 22 and the part 16 of the blank-section is bent inwardly to extend parallel withv the face 21 and form the inner wall 23 of the crown, and again-at rightangles to the wall 23 to form a seat 24 -for the window-pane 2 5 in its trough-like cushion 26 of softrubber or other suitable material for cushioning the glass against fracture from shock, jar and .the like.

The'bendin of the.blanksections firstdescribed as O rming of each the face 20,

4`produces of the part 17 the innerface 27 of the respective sash-rail, which is Jbent along the line 172 on the blank to extend-"at a right-angle to the face 27 `and form the shoulder 28, leaving the part 18 of each blank-section to form, by bending along the line 181th'e oifset wall 29, which 'is united along its edge, -as by brazing or welding, to the opposing edge of 'the seat 24,.the line of junction being indicated at -30 in Fig. 4;

and the -intertting-cornerforming beveled ends ci the rails should be united in `the same vway to complete the sash-frame. (In the edge of the wider part 15 of-each blank-` `section near its ends are formed similar recesses y31, and in direct alinement with each blank-'section a circular opening 32;

, andeircula-r open-ings 33 are formed inthe parts 15 of the blank-sections, Ain alinement with thev recesses 31, vto Aprovide pin-holes (Fig. 7) for the purpose hereinafter eX- plained.I

Prior to uniting the edges of the railsalong the line 30 a clamping-block 311 (Figs.

A8 and 9) is introducedvinto place, one in eachend of each rail. This block comprises a stem 35 providedon-one end with a' curved head 36 conforming 'to and litting within the crown 22, the stem containing a longitudinal bore 37 'of rectangular cross-section terminating at its outer end in a socket 3S havin an .inclined inner wal to exert the' cain-v notion hereinafter described. In placing the blocks 34: in the respective rails,

`each is caused to register apin-socket 39 provided in the part 17 of ico` ' -head36 with a hole 33fto permit a pin 40 -to be .driven through the hole into the socketl y plying a bead to the sash, a key 45`is in- .k that head, with a narrow cylindrical section 451 of a diameter adapting a bead-slot 44 to the 'rectangular bore through lthe stem 35 l of the'clamping-head 3 4; and the keystern f manner to'cause its slots 44 tostraddle. the
