SASH FOR HOLDING GLASS.

Application led May 22,

My invention'rela-tes to metallic window sashes and particularly to division andcorner sashes used for holding large and heavy sheets of plate glass.

One of the objects of my invention is to provide a sash embodying stiifening means to provide a rigid mounting for the glass such that vno strain is produced in the glass.y Another object is the provision of a sash structure in which the visible and glass contacting portions comprise a housing of relatively thin material reinforced by a. stiifening bar hidden from view within the housing.

My invention possesses other` objects and features of advantage some `of which with 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 inl the claims. y

In the drawings:

Figure 1 is a horizontal sectional View thru j a division sash embodying myinvention, and adapted to hold two sheets of glass in planar alignment.

Figure 2 is a side elevation of the tie bar j embodied in my invention.

Figure 3 is a. horizontal sectional view of a corner sash embodying a modified form of my invention, and adapted to hold two sheets of lass at an angle to each other.

Figure 4 is a vertical sectional view of the stationary member alone, showing the bridge and screw construction of the sash. The plane of section is indicated by the line 4-4 of Figure 1.

Figure 5 is a detail of the adjusting screw.

In terms of broad inclusion the sash of my invention comprises a stationary member having spaced sides made of relatively thin material such as brass or bronze, and between which is rigidly disposed a heavy stiffening bar. The edges of the spaced sides are extended to form flanges adapted to engage,l one side of the glass. An adjustable member is provided having flanges for engagement with the other side of the glass. Fas- 1926. serial No. 110,875.

a stationary member preferably formed of relatively thin metal of U-shaped section, and comprising a casing having .spaced vsides 2 and 3 which'A are extended to form flanges 4 and 5 in planar alignment, and against which j the glass sheets Glie. Inter-posed `between the sides 2 and 3 is a stiffening bar 7. The

vstiffening bar is heldin place. by means Yof spacing sleeves 9 and 11 arranged in pair-s near each edgeof the stiening bar andthru whichy pass tie rods or rivets 12 which firmly secure these members to the spaced sides 2 and 3 of the casing, sorthat the casing 'is retained rigidly yin shape and the flanges 4 and 5 kept in planar alignment.

Formed at intervals on the stiffening bar 7 are a lplurality of conical recesses forming seats 13,' and over each seat 13, and secured to the stiffening bar, is a bridge 14 provided with a. centrally disposed boss 16.l A screw 17 is Vthreaded inl eachk of the bosses 16, and on the inner 'en'd of the screw isa cupped head 18 shaped to form-an eiiicient clamping edge in conjunction with the seat13. Coactingwith the stationary member vand engijigeablel with the other side of the glass is. an adjustable member 19 formed with in-V wardly turned glass engaging flanges 2O and 21. Connecting the adjustable member and the iirXed member are a plurality of tiefbars 22 each of which is preferably formed of a single piece of metal having a cross piece 23 at one end adapted to engage the adjustable member behind the anges 20 and 21, so as to be interlocked therewith. The other end of the tie bar is provided with corrugations 24 so as to make the end deformable, and is adapted to extend over one of the seats 13.

When the sash parts are in assembled position as shown in Figure 1, the heads 18 of the screws 17 clamp the ends of the tie bars 22 to the stiifening bar 7 over the seats 13. Since the ends of the tie bars are deformable, they out movement caused by the tightening of the screw. If movement of the tie bar occurs with ltightening of the screws 17, the glass is either loosely held or submitted to undesired strains. In either ease breakage is apt to follow. The cupped edge of the screw engaging the corrugations 2li results only in a clamping pressure exerted in the direction of the axis of the'screw, with absolutely no tendency to move the tie bars transversely. The outer ends of the screws 17 are provided with slots 26 to provide means for adjusting the screws, and the side 3 of the stationary member is provided with openings 27 to perf mit access to thescrews.

In Figure 3 I have shown a corner sash einbodying a modiiied torm of stiiiening bar, and formed to support two sheets of glass 28 at an angle to each other. The edges of the stationary member are ext-ended to form rounded glass engaging lianges 8l and 32 against which the glass sheets may rest at any included angle. The adjustable member 33 is shaped to conform to the angl-e of the glass, the central curved portion 34 giving wide flexibility in this regard. The stiffening bar 36 is secured near one edge only because of the narrowness of the casing 87. Casing and bar are held in rigid assembly by the tie rods 3 8 extending thru the spacing sleeves 39.

l.. A sash for holding glass comprising a stationary member having spaced sides the edges of which are adapted to engage one side of the glass, an adjustable member adapted to engage the other side ot the glass, means for operatively connecting said members, and a bar rigidly disposed between the spaced sides of thestationary,member to form a stiiiening'member therefor.

.having faces in planar alignment and adapted to engage one side of the glass, an adjustable member adapted to engage the other side of the glass, means tor operatively connecting said members, and a bar rigidly disposed between the spaced sides of the sta tionary member to maintain the faces of the flanges in planar alignment.

3. A sash for holding glass comprising a stationary member having spaced sides the edges of which are adapted to engage one side of the` glass, an adjustable member adapted to yengage the other side of the glass, means for operatively connecting said members, a stiliening bar disposed between the spaced sides oi.: the stationary member, spacing means disposed between the bar and the spaced sides, and a tie rod cooperating with the spacing means for rigidly connecting the sides to the bar.

et. A sash for holding glass comprising a stationary member having a pair. of spaced sides the edges of which are adapted to engage one side of the glass, an adjustable inember adapted to engage the other side of the glass, a stiiiening bar rigidly disposed between the spaced sides ofthe stationary inember, a tie bar interlocked with saidadjustable member, a bridge member secured to said stitlening bar, and a screw threaded in said bridge member for clamping said tie bar to said stiiicning bar. f n

5. In asash for holding glass, a member of U-shaped section and formed of' relatively thin material and the edges of which are eX- tended to ferm vglass-contactingflanges, a stiii'ening bar disposed between and parallel to the sides of the member, and means for rigidly connecting the stiiifening bar tosaid member.. i y

v 6. A sash Jfor holding' glass comprising a stationary member having spaced sides the edges of which are adapted to engage one side of the glass, an adjustable member adapted to engage `theother side of the glass, means 'for operatively connecting said members, a

stitlening bar interposed between r,and parallel to the spaced sides of said stationary inember, and spacing means disposed between the lar and the spaced sidesat each edge of said In testimony whereof, I have hereunto set my har-id. v p
