SASH FUR GLASta.

Application filed May 253,

My invention relates to window sashes and particularly to metallic window sashes used for holding large and heavy sheets plate glass.

Une of the objects of my invention is to provide a sash of few parts and simple construction whichwill exert no clamping action upon the glass.

Another object of my invention is to pro vide a sash embodying improved means for securing the parts together.

A further object of my invention is to provide means for preventing the distortion of the lined member of the sash prior to the com.- plete assembly of the sash.

My invention possesses other objects and features of'advantage some oif which witn the foregoing will be set forth in the following description of the preferred form of my invention which is illustrated in the drawings accompanying and forming part of this specification. It is to be understood that I do not limit myself to the showing made by said drawings and description, as i may adopt variations of the preferred form within the scope of my invention as set forth in the claims.

In the drawings: Figure l is a vertical sectional view thru a sash constructed accord ing to my invention, and showing a plate of glass held therein. l igure 2 a plan view of a portion of the adjustable sash bar and the tie bar. Figure 3 is a detail partly in vertical section, showing the bridge and screw construction of the sash. Figure l is a sec tional view of the deformable end of the tie bar, the plane of section being indicated by the line H of Figure 2. Figure 5 is adetail showing the end of the clan'iping screw.

In terms of broad inclusion the sash of my invention comprises a stationary or lined member adapted to engage one side of the glass, and an adjustable member adapted to engage the other side of the Each of these members is formed in one piece, preferably of metal, and the stationary member is formed with a top glassengaging flange and with a base flange. lhe base flange is provided with a raised seat-to which is secured,

at spaced intervals, a plurality of bridge members. lvleans are provided for securing the adjustable member to the stationary memher, and comprise a plurality of similarly shaped tie bars each interlocked with the adas. serial No 110,874.

justabie member, and provided with an extens on overlying the seat beneath the bridges. A plurality of screws threaded one in each of the bridges and each provided with a head on the lower end thereoi, constitute the means for securing the tie bars to the tired member. the screws are constructed of suiiicient length so that before the sash is assembled, and the lined member alone is secured in position on the supporting structure, the screws may be backed out to engage the top flange or the lined member so as to form a support theretor, thereby preventing the top flange of the lined member from becoming distorted by workmen stepping thereon, or by objects falling on the top flange.

More specifically my improved sash comprises a stationary member having wall 2 adapted to be secured to the wooden frame 3. Along its upper edge the wall 2 is extended in a top flange lfor engagement with the plate glassti. fit its lower edge the wall 2 is extended in a base flange comprising the "aised seat flange 6 and the foot flange "i, the latter of which rests upon the supporting structure 8. To the seat flange 6 is secured, at spaced intervals, a plurality of bridge members 9 each of which is provided with a boss 11 positioned centrally of the bridge. Threaded in to each of the hoses 11 is a screw 12, each of which is provided 1th a large flat bottomed head 13, formed with a central recess 14 on the lower end thereof, so as to form a good clamping edge. The bridge members 9 and the screws 12 form the clamping means for securing the sash parts together.

Resting on the foot flange "l" of the stationary member is the adjnstabie member 15, having at its upper edge the inwardly turned glassengaging flange 16 and at the lower edge the inwardly turned foot flange 17. The end of the foot flange 1'!" is formed with a plurality of raised beads 18 extending at intervals lengthwise of the flange.

Means provided for fixedly connecting the adjustable member to the iii. d'member and comprise a plurality of angle shaped tie bars. Each of the tie bars comprises a lower a m 19 and a side arm 21. The .op end of the side arm 21 is adapted to engage behind the glass-engaging flange 16 of the adjustable member, and the lower arm 19 is formed with a raised bead adapted to over, and be interlocked with, one of the raised beads (1 1; All

18 of the adjustable member. To the lower arm 19 of each tie bar is secured a strip oi deformable material 23, preferably lead, corrugated to enhance its detorinability, and adapted to overlie the seat flange 6 of the fixed member. Theside edges 20 of the lower arm 19 are bent over so as to engage the side edges of the deformable strip, and that portion of the lower arm between the bent over edges is preferably corrugated to form a seat for the deformable strip with which it interlocks, thus coaeting with the bent over edges to firmly hold the deformable strip in place. When the head 13 or the screw 12 is imbedded tightly in the deform able material, the tie bar is firmly locked in place without placing any tension on it that would tend to put undesired stresses on the glass.

So as to prevent the top flange l of the fixed member of the sash from becoming distorted by workmen stepping thereon, and by objects falling thereon betore the sash has been completely assembled, I provide the screws 12 of such length as to enga the underside of the top flange 1- when suiliciently backed out from the bridges 9. The screws in this way form an efiicient support for the top flange. The upper end of the screws 12 are slotted at 24: to provide means for turn ing the screws, and the top flange l is provided with apertures 26 positioned directly above the screws 12 to permit access thereto.

So as to permit the stationary member oi the sash to be readily and easily set in place when installing the sash, I provide a plurality oi'f rivets 2?, having large heads which underlie the seat flange and rest upon the supporting structure 8 to serve as a leg and support "for the seat flange. The rivets 2? may be arranged to co-act vith rivets 29 in securing the bridges 9 to the seat flange 6, or they may entirely supplant the rivets Uf course the screw is inserted before the bridge is riveted. This bridge and screw assembly is particularly valuable because screws cannot be lost after they are once placed in the bridge.
