This invention relates to glass holding members, and more particularly to a metallic sash for holding heavy plate glass of the type used in store front construction.

The primary object of the invention is to provide a sash which'exerts no screw clamping pressure on the glass and which comprises inner and outer glass contacting members connected and held against the glass with suflicient resiliency to absorb sudden stresses exerted on the glass by wind pressure or otherwise.

Other objects and advantages of the invention will become apparent as the description proceeds, reference being had to the accompanying drawing, in which:

Figure l is an enlarged cross sectional view of one form of sash embodying the present invention;

Figures 2, 3 and 4 are similar views of other forms of the invention;

Figure 5 is a perspective view ofthe resilient bracket used in connection with the forms shown in Figures 1 and 2;

Figure 6 is a fragmentary sectional view of a slightly modified form of Figure 1; and

Figure 7 is a perspective view of the resilient bracket used in connection with the forms shown in Figure 3.

Referring to the drawing and particularly to Figure 1, the sash includes an inner member I and an outer member 2 which are connected to each other to hold a pane of glass in a manner hereinafter described. In the better grade of store fronts these members are made of extruded metal which has a more attractive appearance than rolled or drawn metal. The inner member I has an offset downwardly turned'flange 3 which is adaptedto be moved into position against a pane of glass 4. A horizontal portion 5 of the inner member extends outwardly and terminates in an upright foot member 6 which is adapted to rest on a base member I, which latter extends entirely across the frame or sill member 8 of the window opening.

The outer member 2 preferably comprises an upright portion 9 from which is offset a glass engaging flange I 0 similar to the inner glass engaging flange 3. A horizontal part i I extends outwardly and terminates in an upright foot member l2 which rests on the base member 1 similarly to the inner foot member 6. Beneath the horizontal member H, a fastening flange l3 extends downwardly into the space outlined by the horizontal member and the foot member l2. It will be understood that the inner and outer sash members and the fastening flange are continuous throughout the length of the window opening.

Spaced at intervals along the sash, as for instance at 12 inch centers, are connecting brackets which in this instance comprise, as best shown in Figure 5, members having a U-shaped'central portion 20 having its free ends 2| and 22 turned outwardly to formv an inner shoulder 23 and-an outer shoulder 24. The inner shoulder23 has 1 downwardly struck wedge-shaped surfaces; 25 formed therefrom. -In the assembly, as.--shown in Figure 1, the inner shou1der'23 is adapted .to be held in abutting relation to the horizontal portion 5 of the inner glass holding member by 5 coaction of a screw 26 and an elongated wedge shaped nut 21, the upper surface of which is cut at an angle supplementary to the slope. of the wedge shaped surfaces 25. v

The outer shoulder 24 of the resilient bracket is bent downwardly to form an upright portion 30 which extends outwardly from either side of the bracket. The upright portion has holes 3| formed therein in the aforesaid outwardly extending portions for the reception of screws 32. 5 These screws are adapted to be engaged in nuts 33 so that the bracket member is fixedtothe fastening flange l3 of the outer sash.

The entire sash assembly is held in position on the window frame 8 by means of screws 34 which extend through the bight portion of the resilient bracket, the base member 1, and into the window frame. It will be seen from the above that when it is desired to fit a pane of glass, the entire sash is assembled by drawing up

screws

32 and 34, and loosely positioning screw 26 in its wedge shaped nut 21. The desired degree of pressure is then exerted on the glass by moving the inner sash member I into engagement with the pane. This member is then retained inits p 0 desired position by finally tightening the screws 26 so' as to draw the wedge shaped nuts 21 against the corresponding wedge surfaces 25..

It will be obvious that sudden shocks and strains on the glass will be taken up in the resilient connecting bracket 20 which permits a slight flexibility, or relative movement between the inner and outer sash members. It has been found that the sash members themselves can be made substantially rigid and that the bracket will afford the necessary resiliency to properly set the glass.

In the event that further flexibility of the sash is desired, the upright portions of the inner and outer sash members, or one of them, may be weakened as at A, along a line parallel to its up per surface, as shown in Figure 6, so as to provide definite axes of flexure about which the sash members may give to a force exerted on the glass. 7

In the form of sash shown in Figure 2 the outer sash member is substantially the same as that shown in Figure 1, and the reference numerals, therefore, are the same. In this instance, however, the base member j'l has an upwardly extending inner surface 40 which in turn is bent to form a gutter 4| substantially parallel to the bottom surface. The inner glass contacting part comprises an upright foot member 42, a horizontal portion 43, the end of which is bent "upwardly into a glass engaging surface 44, which latter terminates in an inwardly, and downwardly I extending part 45, the end of which overliesthe extremity of the gutter member 4| so as to give the inner sash a continuous and finishedappean' ance. .The final setting screw 46 in this instance is concealed beneath the gutter portion 4|, and, similarly to the previously described form, has threaded engagement, with a wedge shaped nut 41. The resilient bracket in this form is identical with that used in connection with Figure 1, so that the description thereof need not be repeated. .Access to the setting screws 46 is had through holes 48 in the inner sash member.

When it is desired to set a pane of glass in a sash of this form the entire sash is assembled, leaving the screws 46 loosely engaged with their wedge shaped nuts. The desired pressure is then exerted on the outer-glass contacting surface IE, and the screws 46 are then tightened to hold the members in the desired relation. The resiliency of this sash is had through the medium of the resilient bracket 20, and also through the inner glass contacting member which may be formed of rolled metal of a thinner gage than is used in the outer sash. It will thus be seen that a compound resilient sash is afforded by this form, a certain portionlof the flexibility being had in the resilient bracket 20, and the remainder being derived from the inner rolled glass contact ing section.

In the form shown in Figure 3, the inner and outer sash members include

upright portions

50 and 5|. The outer sash member has a glass engaging portion 52 which is in a plane offset from the main upright portion 56. The resilient ccnnecting bracket in this instance is made separate from but is operatively integral with the outer member, and'includes an upright part 53 having an offset end portion 54 which bears against the outer glass contacting part 52. The upright portion 53 is held against the upright portion of the outer sash 50 by any suitable means, such as ears 55, struck up from the base of the outer sash and received in suitable holes in the bight portion 55 of the resilient bracket. Similar to the other form of bracket shown, there is provided an inwardly extending shoulder E'I-from which are struck the wedge portions 53.

An intermediate bracket 59is provided, and, together with the inner sash member 5|, is adapted to be fixed to the frame of the window 'as by screws 60. It will be seen that this form of sash seats in a groove on the window opet'i-- ing, the top of which is substantially flush with the top of the inner sash member. The inner sash member has a gutter portion 6| and a glass contacting surface 62. It will be seen that in this instance, as in the form of Figure 2, when it is desired to set the glass, the desired pressure is exerted from the outside, and the setting screws 6| tightened down to retain the glass in its adjusted po-sition.

' In this form, as'well as in Figure 2, the gutters 4| and 6| serve the added function of conduits for condensation occurring on the inner surface of the glass, thus keeping this moisture from running into the show window with the possible injury of goods disposed therein.

Insomeinstances it is necessary to set the glass directlyagainst a frame member. This is particularly true of members adapted to be used with the side and head jambs of a window opening. A form; of the invention adapted for this work is shown in Figure .4 andcomprises an outer sash member 10 having an offset glass contacting flange 1 a horizontal part 12 and a downwardly extending foot portion 13. The resilient 'member 14 in this instance ,iscontinuous throughout the length of the sash and is fastened directly to the window jamb by suitable means, such as a screw 15. The shoulder part 74 of the resilient member has the same wedge shaped members it struck therefrom which are adapted to be engaged by a wedge shaped nut Tl coacting with a screw '18 to hold the sash in adjusted position. It will be seen that the shoulder part of the resilient member is offset from the uppermost part i 19 of the bracket and is connected therewith by a curved portion;j,so asto-afford a definite line of flexure about which the member may give to pressure exerted on the glass.

It will be appreciated that while the bracket members have been described as discontinuous, they may readily be made continuous, as that shown in the device disclosed'at Fig. 4.

Obviously numerous other modifications may be made in the disposition and form of the various coasting parts'without departing from the spirit of the invention as defined in the appended claims.

What I claim is:- v

1. A sash for holding glass, comprising an inner sash member, an outer sash member, a U-shaped resilient connecting bracket for said sash members, the free ends of said bracket being disposed outwardly in a plane offset from the night portion of said bracket, and means to fasten the free ends of said bracketto sa'id sa'sh members in adjusted position.

are established, and means to adjustably fasten said free 'ends'to said sash members.
