sAsH ron HOLDING GLASS.,-

Application filed September 16, 1925.v Serial No. 56,658.

Our invention relates to metallic sashes for holding the glass of windows and show cases and particularly Ato sashes for holding large and heavy sheets of plate glass.

One of the objects ofthe invention is the provision of a sash which exerts no clamping action upon the glass.

Another object of the invention 'is the provision of improved and simplified sash members.

Another object of the invention is the provision of improved means for securing the sash members together.

Another obj ectof the invention is the provision of a sash of the character described readily and cheaply formed from sheet metal and having a minimum number of parts, which can be assembled y bya few simple operations to hold the glass securely without pressure thereon.

The 'invention possesses other objectsv and features of advantage, some of which, with the foregoing, will be set forth in the ,following descriptionA of the preferred form of our invention which is illustrated in .the drawings accompanying and forming partof the specification. It is to be understood that we do not limit ourselves to the showing made by the said drawings and description, vas'we may adopt variations of the preferred form within the scope ofour invention as set forth in the claims.

Referring to the drawings: l

Figure 7 is a perspective View of the modified form of tie bar from the structure shown in Figure 6.

` Figure 7 Figure9 is a perspective view of the nonslip conformable plate embodied in the structure shown in Figure 6.

In general terms the sash of our invention comprises a stationary sash bar adapted to engage one side of the glass, and an adjustable sash bar adapted to engage the other side of the glass.` Each of these members is formed in one piece, the stationary sash bar including a raised seat and a lower foot fiange resting upon the supporting structure. At intervals 'tie Ibars extend from the adjustable sash bar to the seat. One end of the -tie bar is permanently secured .to the adjustable sash. bar, and means are provided for clamping lthe other end to theseatto hold the sash 4bars together with the glass therebetween.' The end of the tie bar adjacent the seat is of conformable character, and the vclamping means comprises a .headed screw, the head of which ombeds itself in the end vof the tie bar. This occurs without placing the least tension on the tie bar so that there is no tendency to put a pressure upon the glass when the parts are assembled. Improved means are provided for giving Athe conformable'character to the tie bar end and also for so curing the tie bar in the adjustable sash bar. Improved setting blocks .are also provided for permittingr the setting of the glass in the'- sash, and these setting bloclisremain in the sash as permanent supports for the glass.

' In greater detail our invention comprises a stationary sash bar having the wallportion 2 adapted to be secured by screws 3 to thel stationary member comprising the portions 2, 6, 8 and 9l are formed integrally, and preferably by rolling froma single sheet of suitable material. At intervals the seat 8 is pro-A vided with screwsV 11 ,threaded therein. The

screws are provided with largeheads 12, and i-f desired may be eoned on the under side to directly rests.

correspond with conical depressions in the bottom of which the screws are threaded.

Resting on the foot flange 9 of the stationary sash bar is the adjustable sash bar 16, having at its upper edge the inwardly turned glass-engaging flange 17, and at the lower edge t-he inwardly turned base flange 18, from which is turned up the tab 19. Interlocked within the adjustable sash bar is the foot of the tie bar, the end 2l being engaged behind the flange 17. Formed in the tie bar is an aperture 22 which is engaged by the tab 19, so that the tie bar is securely interloclred within the adjustable sash bar. The free end of the t-ie bar is provided with a slot 23 lborderedwith corrugations 2A. ln .use the slotted end of the tie bar slides under the head l2 of the clamping screw and when the screw is tightened, the head imbeds itself in the corrugated portions of' the tie bar and locks it securely in `place without placing any tension on it tending to put undesired strains on the glass 25. The tie bar as a whole is an angular member and to prevent flexing between the parts thereof, we provided flanges 26 along the edges so that rigidity is assured.

instead of corrugating the end of the tie bar, we may form the tie bar end with a roughened or toothed surface, for example, by punching thru the metal as shown in Figures 7 and 8, to leave upstanding beads or teeth 3l. W hen this form of tie bar is used, we interpose a conformable plate or washer 32, conveniently made of lead, between the roughened surface of the tie bar and the head of the screw, so that the pressure of the screw causes the head thereof to embed itself slightly in the lead and at the Sametime press the lead upon the roughened surface of the tie bar, thus locking all securely together. We show this construction in Figure 6, and it will be observed that the under side of the screw head and the seat on which the tie bar rests are both flat.

It will of course be understood that the tie bars are placed at intervals along the sash and in suflicient numbers to insure the integrity of the sash structure as a whole.

i ln order to permit ready access to the screws, when thel glass is being set in the sash, an aperture 37 is left in the top flange 6 above each screw.

When the glass is placed within the sash it is set upon blocks 38 formed as shown in Figures l and 5 and preferably provided with a leather facing 39 upon which the glass One of these blocks is conveniently placed about every four feet in the sash, and after the glass has been'set on the blocks as indicated in Figure 4- it may be pushed upagainst theflange 7, the blocks forming shoes and sliding into the position l. ln sash for holding glass, a stationary sash bar comprising a wall adapted for conneotion to the supporting structure, a top flange'integral with the wall and forming a fixed glass-engaging edge, a base flange integral with the wall and providing a tie bar seat., an adjustable sash bar adapted to engage the opposite side of the glass, a tie bar interlocked with the adjustable sash bar and extending over said scat, and means for locking the tie bar to the seat.
