CLARENCE VICTOR TUNES, OF TORONTO, ONTARIO, CANADA.

WINDOW-OPERATING DEVICE.

Specification of Letters Patent.

Patented Oct. 21, 1919.

Original application filed 0ctober14,1918, Serial No. 257,952. Divided and this application filed December 1 0 all whom it may concern:

Be it known that I, CLARENGE VIc'ror. Jones, a citizen of the United States of America, and resident of 230 Yonge street, city of Toronto, county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in lVindow-Operating Devices, of which the following is a specification.

The invention relates to improvements in window operating devices as described in the present specification and illustrated in the accompanying drawings that form a. part of the same.

The invention consists essentially of the novel means employed for securing a window in any desired position against the pressure of springs adapted to open same.

The objects of the invention are to provide a means whereby casement windows opening to the outside may be adjusted without the necessity of the operator reach ing out of the window, to avoid displacement of screens and the like when adjusting the window, to prevent damage caused by windows being blown open and shut and generally to provide a window operating device which will be inexpensive to manufacture, durable and efficient.

This application constitutes a division of my application, Serial No. 257,952 filed October 14th, 1918.

In the drawings Figure 1 is a view of a window locked to an open position.

Fig. 2 is a cross sectional view taken on the line AA of Fig. 1.

Fig. 3 is a detail of a portion of the chain secured in the locking bracket.

Fig. 4 is a detail of two of the links of the chain.

Fig. 5 shows a modified form of link.

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings the window 1 is provided with two or more reverse hinges 2 adapted to exert an outward pressure on said window to open same, (the construction of said hinges being described and claimed in my previous application.)

The outward movement of the window caused by the pressure of the spring hinges 2 is controlled by means of a chain 3 secured at one end of the window sash in any suitable form of swivel attachment 4, (it thought not to be necessary to show said Serial No. 266,119.

swivel attachment in the drawings as any of the known forms may be used) and having its other end operating through a catch or bracket 5.

The chain 3 is composed of solid metal links 6 perfectly circular in cross section, one end of each of said links being provided with a centrally disposed flat projection 7 having its end tapered inwardly as at 8 and the other end of each of said links having a centrally disposed longitudinal slot 9 therein adapted to accommodate the projection 7 from the adjacent link and to be secured thereto by a pin 10. The inner end wall of the slot 9 is cut at an angle corresponding and the end of the projection 7 so that links will fold in one direction only.

The bracket or look 5 through which the chain 3 operates is preferably formed from a flat piece of metal having its side edges turned inwardly at right-angles forming vertical flanges 11 and 12, the flange 11 being cut away toward its lower end and being provided with a circular opening adjacent to the upper end thereof adapted to accommodate said chain while the upper end of the flange 12 terminates slightly below the opening in the flange 11 to permit of the chain projecting in a straight line from said openlng.

In Fig. 5 a modified form of chain is shown in which the links are formed in two longitudinal sections secured together and spaced at one end by a fiat member 13 corresponding and the projection 7 and adjacent to the other end being spaced by a plate 14: having its end shaped to correspond to the end of the member 13 to permit of the links falling in one direction only. The links are pivotally secured together by pins similar to the pins '10.

In the operation of the invention where it is desired to adjust the window the hanging portion 15 of the chain is raised outwardly free of the flange 12 by means of the swivel attachment and extended in a straight line over said flange 12 so that the pressure of the hinges 2 will draw the chain outwardly through the opening in the flange 11. When the window has opened the required distance the chain is turned slightly and again folded between the flanges 11 and 12 where it is securely held.

It will of course be apparent that when the window is covered by a screen it is only necessary to slot the frame of said screen to accommodate the chain 3 and the window may then be adjusted without interfering with said screen.

lVhat I claim is 1. In a window operating device, the combination with a window adapted to be spring held normally to an open position of a vertically channeled bracket secured to the frame of said window, flexible means swivelly secured to said window and pro-v nel, the flange on the inner side edge terminating slightly short of the upper end of said bracket, and a, chain secured to said wmdow in a swivel o1nt and extend ng through an opening through the outermost of said flanges above the inner flange and adapted to be turned downwardly between said flanges.

3. In a window operating device the combination with a window adapted to be spring held normally to an open position, of a bracket secured to the frame of said window and provided with flanges at opposite side edges thereof forming a vertical channel, the flange on the inner side edge terminating slightly short of the upper end of: said bracket, and a. chain swivelly secured to said window and comprising a alurality of solid links pivoted together to fold in one direction only and extending through an opening through the outermost of said flanges above the inner flange and adapted to be turned downwardly between said flanges.

Signed at Toronto, Ont, this 5th day of November, 1918.

CLARENCE VICTOR JONES.
