Application March 4, 1931. Serial No. 520,046 `'l Claims. (Cl. v2li-56.4.)Y

My invention relates to metal Iwindow sash or store front sash adapted to support large and heavy panes or plates of glass. One of its objects is to provide an improved sash comprising a 5 rectangularv sash or frame provided4 with supports for a plate of glass and with a` pluralityof glass clamping jaw members adapted to forman outside finish and to retain the glass in position relative tothe sash. Another object is to provide an improved sash or frame relative to which clamping jaws and jaw tensioningmembers and glass supporting members are adjustably supported, Another object is to i provide an improved sash adapted to receive the glass from 4 one. side and to have a series of glass clamping g jaw members applied over the edges ofthe glass after the glass has been seated in the sash. `Another object isv to provide an improved metal sash in which the glass Vis adapted to be applied from one side andra series of independent clamping jaw members applied detachably4 and removably to facilitate removal and replacement of the glass if required, and adapted to uniformly clamp the glass in place with a sufficient degree of resiliency to avoid danger of fracture of the glass. My invention also comprises certain details 'of formand arrangement, and combination of com- A ponents all of which will be fully set forth in the description of the accompanying drawing, in

which:

Difficulty has been experienced heretofore in providing sashes adapted to support largea'nd heavy glass plates with satisfaction..v Also in providing for conveniently placing the glassin the sash or frame, and in removing or replacing the glass if necessary. Also in holding the glass firmly in the sash Without liability to fracture .the glass. My improved sash andglassmounting apparatus obviate these several difficulties, and provide an improved sash and means of reliably supporting the glass therein, and conveniently removing and replacing the glass. I am valso enabled to construct high grade sash members from stock bars of extruded metal at relatively low cost in material and labor. Y l

The accompanying drawing illustrates one embodiment of my invention in which vl5 represents a pane of glass and 16 represents an open recy tangular metal frameV constructed preferably from sections cut from stock bars of extruded metal of substantially the cross sectional pattern shown in Fig.'5, by mitering the ends of lthe bar sections and brazing or otherwise uniting the* meeting ends ofkbars to form a rigid metal frame as shown in Fig. 1. Thevbar sections of the frame 16 are preferablyof angular or'channel shapeV in cross section to `afford rigidity in the finished frame compared-with the weight of metal employed. They are Valso providedwith a' rib or ledge 17 forming an annular` support for one face of the glass, and with a channel 18 along which the jaw engaging levers 19 and the glass supporting members 20 are adjustableand may `be spaced apart relative 4to the framel previously to uniting the sections t'o form the frame 16. The channels 18 are preferably of cylindrical pattern, and are engaged by counter-part cylindrical sections 22 forming part of the members 19, and counterpart sections 24 forming part of the members 20, to thereby enable the members 19` and 20 to slide endwise inthe channels 18, while the free ends of the members 19 and 20 have a Vlimited amount of movement pivotally about their sections 22 and 24, relative tothe frame 16. Once the frame 16 is assembled the members 19 and 20 are not detachable from the frame 16.r If desired, after the sections of frame 16 have been united, the members 19 and 20 may be adjusted tosubstantially the positions shown in Fig.' 1 or to other desired positions and then members 19 and 20 locked against further adjustment endwise of the channels 18 by striking the'edges of the channels 18 upon opposite sides of said members 19 and 20 with a center punch or other tool to distort the edges of the channel 18 at 2 5 and lock members 19 and 20 to the desired localities relative tothe frame 16.` The members 20 have dovetail recesses 26 adapted to receive blocks of rubber, ber or similar material 2'1upon which the lower edge ofY the glass is 'adapted torest at two or more localities, depending upon the size of thelplate of glass.` Ordinarily two members 20, placed'near opposite ends of the bottom of the sash are suicient tc support the glass. The lower faces 28 of members 20 rest upon the inner' face of the lower section of the frame 16. A number, two or more lever members 19 are spaced along each section or side of the frame 16. The sash 16 is set in the store front or other locality, and is ready to have the glass introduced upon the glass supporting members 20 and 27 from the outside of the sash.

The members 19 and 20 are produced by severing a stock bar of extruded metal into short sections.

A series of clamping jaw members 30, which are cut to the desired lengths from extruded metal stock bars of substantially the cross sectional pattern shown in Fig. 4, with their ends mitered, are introduced into place one after another with reference to the frame 16 and the glass and the members 19 and 20. The bar sections 30 are provided with an edge which rests upon or against the inside of the extreme edge 31 of the sash 16. The upper edge 32 of the sections 30 forms jaws which engage the outer face of the glass plate opposite to the jaw or ledge 17. The bars 39 are also provided with inwardly extending ledges 33 terminating in a cylindrical bead 34 which bead 34 is engaged in a Yrecess 35 in the free end of each clamping lever 19 as the bar 30 is introduced into position relative to 30 the frame 16. After a bar 30 has been adjusted to position, screws l33 threaded through perforations 39 in the frame 16 serve to engage the members 19 and to apply pressure to each mern ber 19, intermediate of its section 22 and its section 35, to thereby causer the section 35 of each member 19 to bear upon the bead 34 and cause the barr30 to turn where its edge 40 rests as a fulcrum upon the edge 31 or the frame 16, thereby causing the jaw 32 of the bar Sdto press against the outer face of the glass and to clamp the glass firmly between the jaw face 32 and the jaw face 17. The members 19 are preferably constructed to have sufiicient resiliency so that when the screws 33 are tightened the jaw 32 will act with suiicient force to hold the glass in place without liability to pinch or fracture the glass. The members 19 are preferably provided with stop membersel, which ultimately contact with the inner face of theframe 16 to limit the strain applied by screws 38 to the jaw faces 32. The frame 16 is preferably provided with a channel 43 which being located inside o the glass serve to catch and drain away any water of condensation accumulating upon the inside of the glass. Each section or bar 30 is introduced independently, and if required may be independently detached and removed by loosening the screws 38. The frame 16 with members 19 and 20 attached is adapted to be shipped from the factory as a unit, and the bar members 30 are adapted to be compactly packed for shipment.

The apparatus herein shown and described is capable of considerable modification within the scope of theclaims, without departing from the spirit of my invention.
