METALLIC SASH. APPLICATION FILED SEPT. 21, 1915.

VANIA.

METALLIC SASH.

Patented May 29, 1917.

Application filed September 21, 1915. Serial N 0. 51,844.

To all whom it may concern:

Be it known that I, GEORGE B. KOHLER,'L citizen of the United States, residing 1n Philadelphia, Pennsylvania, have invented certain Improvements in Metallic Sashes, of which the following is a specification.

My invention relates to certain improvements in a metallic sash in which the sheet of glass is held. I

One object of the invention is to construct the sash so that the glass can be inserted or removed quickly and easily.

A further object of the invention is to construct the sash so that the use of putty, felt, or rubber is avoided.

The invention is particularly adapted for use in connection with the sash used on railway passenger cars, but it will be understood that it can be used in the construction of window sashes in general without departing from the essential features of the invention.

In the accompanying drawings Figure 1, is a sectional perspective view illustrating my improved window sash and showing the glass in position;

' cross bars 3 and 3,

Fig. 2, 1s a sectional view of the upper portion of the sash showing the glass locked in. position;

Fig. 3, is a view similar to Fig. 2, with a part of the sash withdrawn so as to release the glass;

Fig. 1, is a detached sectional view of a portion of the sash frame;

Fig. 5, is a sectional perspective view of a portion of the clamping bar;

Fig. 6, is a perspective view of one of the adjusting screws used in connection with my improved sash; and

ig. 7, is a detached perspective view, showing one of the corners of the sash.

eferring to the drawings, 1 is the sash having side bars 2 and upper and lower respectively. The cross 2 are made as clearly shown in Fig. l, and have a body portion 4 and deep flanges 5 and, when the frame is assembled, the ends of the cross bars 3 bars 3 and side bars a and 5 are slightly reduced, Figs. 1 and 7, so

as to extend into the ends' 6 of the side bars. The parts are secured by sweating or brazing. In some instances the top and bottom rails may be flared and the side bars may extend into the flared ends, if found desirable in manufacturing.

7 is the clamping bar, which is made as illustrated in Fig. 5 andv consists of a body portion 8 and curved, inturned flanges 9, the ends of which overlap as illustrated in Fig. 5, and form a groove 10 for the edges of the glass sheet 11. These edges are not secured together, but there is sufficient spring in the metal to allow the flanges of the clamping bar to bind yieldingly upon the glass, so that the use of putty, felt or rubber at this dispensed with.

secured to the body portion 8 of the clamping bar 7 as clearly shown in Fig. 5. Each screw has a shoulder 14 bearing against the inner side of the body portion 4 of the bars 2 and 8 forming the frame 1, and the body portion is perforated, as at 15, and a red portion 16 of the screw projects into t e perforation but is flush with the outer surface of the frame. This reduced portion is slotted, or otherwise formed, for the reception of a screw driver, or other instrument, by which it can be turned from the outside.

As it is only necessary, the glass, to have three adjustable, I preferably dispense with the clamping bar 7 and shape the cross bar 3 to form a groove 17 for the edge of the glass, and I form an undercut groove 18 in the body of the bar 3 to receive the tongue 19 of the rubber strip 20, which has a narrow in order to remove sides of the sash 1n this manreadily manipulated than the bottom bar.

In applying a sheet of glass to the sash,

all that is necessary is to turn the screws in the upper cross bar 3 and side bars 2, so

the frame are closer that the clamping bars will assume the position indicated in Fig. 3. There is no spring required and these bars are merely pushed back into this position. The side flanges of together at their eX- tremities than at the base so that these bars have a tendency to pinch the locking bar and to hold it rigidly. When the glass is in position, the screws are turned so as to project the clamping bars and as they are pro- 'ected they close in upon the glass, the edges of which enter the grooves 10 in the clamping bars and come in contact with the overlapping edges and, on continuing the move ment of the screws, the inturned portions of the flanges yieldingly press upon the sides of the sheet of glass, holding it in position.

I claim 1. The combination in a window sash, of a hollow metallic frame, a clamping bar mounted in said frame, and means for moving the clamping bar forward to engage the glass, said clamping bar being made of metal and having yielding flanges bent to form a recess for the reception of the edge of the glass, the edges of said flanges being disconnected and overlapping and arranged to bear on the edge of the glass so that when the clamping bar has moved forward it will press upon the edge of the glass and on continuing the movement it will yieldingly bind upon the side surfaces of said glass holding the glass firmly to the sash.

2. The combination in a window sash, of a hollow metallic frame, a clamping bar mounted in said frame, said clamping bar being made of sheet metal and having yielding flanges bent to form a recess for the edge of the glass, the edges of said flanges being disconnected and overlapping and arranged to bear on the edge of the glass so that when the clamping bar is moved forward it will press upon the edge of the glass and upon continuing the movement it will yieldingly bind upon the side surfaces of said glass and thereby hold the sheet firmly in the sash, nuts secured to the back of the hollow frame, and a screw adapted to each nut and bearing against the interior wall of the hollow frame, said screw having a reduced portion extending into anopening in the sash so that the screw can be turned on the outside to adjust the clamping bar to the glass.
