n and Patented Oct. 14, 1930 rear OFFICE HERBERT E. WHITE, OF- YOUNGSTOWN, OHIO GASEMENT wrnnow Application filed September 19,1927, Serial No. 220,337.

The present invention relates to window construction and particularly to the construction of'casement windows.

Among'the objects of the invention is a casement window and frame provided with a hinge which causes the window to be moved bodily away from the adjacent side of the frame for either ventilation or cleaning purposes.

Other objects will readily appear to those skilled in the art upon reference to the following description and accompanying drawing, in which Fig. 1, is a perspective view of a window sash and frame embodying the invention.

Fig. 2, is a section on line 22 of Fig. 1

Fig. 3, is a section on line 33 of Fig. 2. 'As shown, the window frame 10 is preferably of Z-sectionmetal members cut and welded to rectangular shape so as to present on its inner face an inwardly extending flange 11 and on its outer face an outwardly extend- 1 ing flange 12.

@The sash 15 or window proper is also made in the usual manner by welding suitable projecting arm 21 which in turn is carried by a'flat portion 22 adapted to be secured as by screws 23 to the sash 15. e Pin 20 has a bearing in a block 25 adapted to slide in a slotted guide block 26 secured to frame 10 as by screws 27. It is preferred also to provide means for regulating the slid- F ing of block 26 so that, while the sash 15 may be easily swung open and shut, it will remain many partly open position without additlonal securing means. This accomplished by aplate 28 secured to block 26 and extending over block 25. Through the securing screws 29, adjusted pressure may be put on block 2550 as to cause sufficient friction thereon to hold the sash in any desired position.

The upper hinge pin may be similarly made and mounted but'preferably cooperates directly with a suitable guide carried by frame 10, eliminating parts similar to block 25 and guide 26.

, Carried also by frame 10 is a U-shaped member or controlling bail 30 hinged to frame 10 as at 31 and adapted to lie in the channel formed between flange 11 and the outer flange of the sash when the latter is closed.

The free ends of bail 30 are hinged to the sash'by means of bolts 32 at such a distance from the lineof the hinge pins as will produce the desired translation of the sash. This distance in the form shown is about one-fourth of the width of the sash. The free arms of bail 30 are, of course, of less length than the width of the sash by the distance from bolt 32 to the adjacent edge of the sash.

The operation of the present device is easily seen from the drawing. In opening the window, the sash will swing on the hinge pins and the bail 30, acting as a fulcrum, will cause the pins to move laterally toward the center line of the frame, suitable stops (not shown) being of course provided. By using the form of controlling bail shown, both ends of the sash areconstrained to move together so that the hinge pin alignment is always maintained.

Now having described the invention and the preferred form of embodiment thereof, it is to be understood that the said invention is to be limited, not to the specific details herein set forth but only by the scope of the claims which follow.

I claim:

1. In a casement window, a sash having upper and lower hinge pins, a frame having slidably mounted bearings for said pins, said bearings permitting lateral and pivotal movement of said pins, and a rigid U shaped bail hinged at its intermediate portion .to said frame on the side opposite to the closed window position of said hinges and having arms integral therewith and hingedly connected to the sash at top and bottom respectively and at points spaced from said pins to constrain both hinges to likemovement in v said frame. 7 V

2. In a casement Window, a sash having upper and lower hinge pins, a frame having bearings for said pins, at least oneof said loearings consisting of a block slidaloly mounted in a guide in said frame, both of said bearings permitting lateral and pivotal movement of-said pins, and a rigid U shaped bail hinged at its intermediate. portion to said frame on the side opposite to the closed window portion of said hinges and having arms'integral therewith and hingedly connected to the sash. at topand bottom respectively and at points spaced from said pins, to constrain both hinges tolike movement in said frame.

3. In a casement window, a sash having 23 upper and lower hinge pins, a frame having bearings for said pins, at least one of said bearings consisting of a block slidably mounted in a guide in said frame, adjustable means forholding the slidableblock in any desired a; position in the guide, both of said bearings permitting lateral and pivotal movement of said pins and a rigid U shaped bail hinged at its intermediate portion to said frameon the side opposite to the closed window por- 59 tion of said hinges and having arms integral therewith and hingedly connected. to the sash at top and bottom respectively and at points spaced from said pins, to constrain both hinges to like movement in said frame. 55 HERBERT E.
