SUPPORT FOR WINDOW PANES.

Application filed February 11, 1926. Serial No. 87,706.

My invention relates to a metal window sash and more particularly to an outer clamping plate and means for connecting it to an inner clamping member.

The object of my invention is to provide a construction whereby the outer clamping member of a metal window sash may be accurately positioned and held in such a manner that it may exert yielding pressure on the glass.

The construction and the minor objects of my invention will appear as the description proceeds.

In the accompanying drawing forming a part of this specification, Fig. 1 is a crosssection of a sash embodying one form of my invention; Fig. 2 is fragmentary front elevation of the same, and Fig. 3 is a view similar to a portion of Fig. 1, but showing a different form of face plate.

The sash is shown as applied to a lower frame member or sill 10 which has a horizontal portion '11 beneath the glass sheet 9, and

' a riser 12 behind the lower edge of the glass.

This sill is shown with a sheet metal cover 13 having an upturned flange 14 at its rear edge adjacent riser 12. An inner glass engaging member 15 has a substantially horizontal portion 16 the front edge of which is turned down to form a flange or lip 17 adapted to contact the rear face of the sheet of glass. At the rear edge of'horizontal portion 16 there is a downwardly directed portion 18 adapted to rest against riser 12 and having an offset portion 19 at its lower edge adapted to extend downward in front of flange 14 into contact with sill covering 13. Preferably offset portion 19 terminates in aforwardly directed portion 20 adapted to lie on top of covering 13.

The outer clamping member or face plate 21 has a glass-engaging flange 22 at its upper edge, and has a head 23 at its lower edge adapted to rest on sill covering 13 and to abut against the forward edge of portion 20 of rear plate 15. A substantially horizontal flange 24 extends from bead 23 and is raised enough to overlie portion 20 with a slight normal clearance.

A sheet metal box-shaped bracket 25 lies on one side 26, which rests on portion 20, and has its bottom perforated to receive a screw 27 by which it and clamping plate 15 are held in place a ainst riser 12. The upper side 28055 the racket is provided with a screw-threaded bushing 29. The front side of the bracket is open.

A substantially L shaped member 30 has the upper end 31 of its upright arm resting against flange 22 while its horizontal arm 32 extends rearward into bracket 25. The angle 33 of member 30 rests upon flange 24, and a portion 34 of flange 24 may be bent upward through a hole 35 in arm 32.

Arm 32 is slanted upward at 36 and then has its rear end turned down at 37 to rest upon side 26 of bracket 25 and support the rear end of portion 36. Flanges 38 are preferably provided at the sides of member 30 to stiffen the member and maintain its two arms at a substantially constant angle.

A screw 39 is passed downward through bushing 29 and has a rounded lower end 40 adapted to press against slanting portion 36 of arm 32 and press the arm downward and at the same time draw it to the rear by means of cam action against the slanting surface.

The forward edge 41 of bracket bottom 26 is turned upward slightly, so as to furnish a yielding support for arm 32,. and flan e 24 affords a yielding support for the ang e of member 30.

Bead 23 rests upon the unyielding surface of sill covering 13, and is held against rearward movement by portion 20 of back plate 15, while the construction of offset portion 19 is such that bead 23 may force portion 20 slightly to the rear, this movement will not be enough to materially change the angle of the front plate.

It will be readily understood from the above description that, when the parts are as-- sembled in the manner disclosed, downward movement of screw 29 results in cam action against portion 36 and draws member 30 to the rear and thereby brings the front plate against the glass and against the front edge of portion 20. Member 30 presses downward on flange 24, and this insures against bead 23 slipping over the edge of portion 20. The slight yielding allowed by

portions

19, 41 and 24 is suflicient to relieve undue strain on the glass, and at the same time the front clamping plate is not allowed to move to an objectionable extent. The comparative rigidity of member 30 aids in preventing un'due movement of the front clamping plate and in confinin any yielding to the places mentioned a ove.

In Fig. 3 an outer clamping member or face plate 21 is shown having upper and lower flanges like those shown in Fig. 1, but having the intermediate portions extending along different lines. Parts shown 1n Fig. 5 3 are designated by the same reference numerals as corresponding parts in Fig. 1. wlth the letter a added. Itwill be noted that flange 24* is slightly widened, and that the upright arm of member 30 1s modified to fit within the modified face plate. These changes are without material effect upon the operation of the device.

While I prefer to use the portion 2Q, 1t might be omitted in some cases, and various 16 other obvious changes maybe made within the scope of the appended claims, WhlCh define my invention.
