JAMES TORESAN, OF SUSANVILLE, CALIFORNIA.

WINDOW OPENER AND CLOSURE.

Application filed February 21, 1925. Serial No. 10,906.-

To all whom it may concern:

Be it known that I, JAMES TORESAN, a citizen of the United States, residing at Susanville, in the county of Lassen and State of California, have invented new and use ful Improvements in Window Openers and Closures, of which the following is a specification.

This invention relates to improvements in window openers and closures.

The principal object of this invention is to provide means for openingand closing windows without exerting considerable manualefl'ort.

Another object is to produce a device of this character which may be applied to the ordinary window without altering the con.- struction of the same.

An additional object of this invention is to provide means whereby when the window is entirely closed or entirely opened the device will become inoperative.

A still further object of this invention is to produce a window opener which is mechanically simple and therefore cheap to install.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a front elevation of a window partly broken away in order to show my device attached thereto,

Figure 2 is an enlarged detail view of one of the worm engaging brackets, and

Figure 3 is a side elevation of Figure 1.

It is often diflicult to raise and lower windows, particularly in large buildings employing metal frames, the result being that considerableeffort must be exerted in order to accomplish the opening or closing of the same. I have, therefore, devised means whereby this effort may be eliminated through the employment of gearing to overcome the effort which would be otherwise required.

'In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a window frame, the numeral 6 the upper sash and the numeral 7 the lower sash, within which are panes 8 and 9, respectively.

Attached to the sash 6 is a bracket 11 and to the sash 7 is a bracket 12. These brackets extend outwardly through the windows and slide in grooves 13 and 14. formed in the side of the casing. The bracket 11 engages the worm 16 formed upon the shaft-15, While the bracket 12 engages a worm 17 formed upon the shaft 20. These worms are provided with right and left hand threads such double bevel gear 26 slidably keyed to a shaft27 and suitably journaled below the ends of the shafts 15 and 20.

A sprocket 28 has a chain 29 reeved thereover, which chain engages a sprocket 31 mounted upon the shaft of a motor 32. A handle 33 is provided with a worm 34 the nose of which engages a collar 36. secured to the gear 26. This permits the sliding of the gear 26 so as to engage either of the gears 23 or 24. The usual weights 37 are provided as disclosed to advantage in Figure 1.

Assuming that my device has been attached to a window and it is desired to lower the upper sash the motor 32 is started and the handle 33 is pushed so as to bring the gear 26 into contact with the gear 24. This will impart rotation to the shaft 15, upon which the worm 16 is formed. The spring 21 will force the bracket 11 into contact with the screw in sucha manner that the rotation of the shaft will cause the bracket to move downwardly thereon, car ing with it the sash 6.

Assuming that the sash has traveled the entire distance downwardly, the bracket will leave the worm and rest upon the sprin 22 at this time the handle 33 is inanipulate so as to withdraw the gear at 26 from engagement with the gear 24. When it is desired to raise the sash the gear 26 is again moved tated in any suitable manner other than by into contact with the gear 24 and the spring .26 will push the bracket into contact with the worm in such a manner as to cause the w sash and its attached bracket to move up 6 wardly and into closed position. The lower the means shown normally by the motor 32. It might also be advantageous to have a continuouslyrunning shaft positioned beneath a plurality of windows or on the other hand,

it might be desired to employ a hand crank. by

It will thus be seen that my device will accomplish all of the objects above set forth. It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be re sorted to without departing from the spirit of the invention or the scope of the subjoined claim.

with the direction of movement thereof, a

worm formed on said shaft, said worm having a right and left hand thread, said worm being engaged by said; bracket, a helical spring surrounding one-end of said shaft and adapted to contactsaid bracket, a sec+ ond helical spring surrounding said shaft, at a point remote from said first mentioned spring in such a manner as to be engaged said bracket, after travelling throughout the length of said worm, means for rotating said shaft, said means comprising a gear, a

shaft positioned below said gear, a sliding.

gearpositioned on said second mentioned shaft, means for rotating said second mentioned shaft, and a lever for moving said second mentioned gear into and out of engagement with said first mentioned gear.

In testimony whereof I aflix my signature.

JAMES TORESAN.
