July 117, 1934. H. E. FULLER WINDOW OPERATING MECHANISM Filed Feb. 24, 1932 Patented July 17, 1934 UNITED STATES l/VINDOW OPERATING MECHANISM Harris E. Fuller, Norfolk, Va., assignor to Hermonie Fuller, Norfolk, Va.

Application February 24, 1932, Serial No. 594,808

2 Claims.

This invention relates to power operated means for raising and lowering the sash in windows in which motor driven threaded shafts, sometimes referred to as worm shafts, are provided in the vertically disposed spaces which are usually provided for sash cords for raising and lowering the upper and lower window sash together with simple means for installing and operating the threaded shafts and convenient control means are provided for rendering operative or inoperative the motor driven means for raising and lowering the windows.

An object of this invention is to provide motor driven means for raising and lowering window sash wherein means are provided which can be installed in combination with the conventional window sash in which threaded shafts are provided for installation in the space usually provided for sash cords, together with a motor for driving each threaded shaft and a switch for controlling the direction of rotation of each motor, the motor being reversible and being controlled by a reversible switch for raising and lowering the window sash independently of each other.

Some of the objects of the invention having been stated, other objects will appear more fully when taken in connection with the accompanying drawing, in which- Figure 1 is an elevation of a window frame equipped with sash and showing operating means therefor, the view being taken from the inside of the window;

Figure 2 is a vertical sectional view taken along the line 22 in Figure 1;

Figure 3 is a vertical sectional view taken along the line 3-3 in Figure 1;

Figure 4 is a transverse sectional view taken along line 44 in Figure 1;

Figure 5 is a detail of one of the reversible switches for operating one of the motors.

Referring more particularly to the drawing, the numeral 10 indicates a window frame having a vertically disposed cavity 11 therein and being disposed on one side thereof in which reversible motors 12 and 13 are mounted. Each of these motors 12 and 13 is a conventional reversible motor and can be operated in either direction by any conventional means but in the drawing, I have shown a cable 14 leading from motor 12 and a cable 15 leading from motor 13, cable 14 being connected to upper switch 16 and cable 15 being connected to lower switch 17. The switches are identical in structure and only the upper switch 16 is shown in Figure 5 in which wires 18 and 19 are connected to a stationary block 20 and another stationary block, identical to stationary block 20, but not being shown in Figure 5, ap-

pears to which branch wires 19a and 18a lead wires 18 and 19 can be reversed. The identical structure appears as to switch 17.

Upper window sash 22 has lug 23 secured to one side thereof and lug 2 1 secured to the other side thereof having a vertically disposed threaded hole adapted to respectively whi receive worm shafts 25 and 26 ch worm shafts have bevel gears 27 and 28 respectively on the upper end thereof which mesh with bevel gears 29 and 30 respectively on shaft 31, which shaft 31 has bevel gear 32 meshing with bevel gear 33 on motor shaft 34.

Lower window sash 35 has lugs 36 and 37 secured thereon adapted to receive worm shafts 38 and 39 respectively which on their upper ends, have bevel gears 40 and 41 respectively which are adapted to mesh with bevel gears, 42 and 43 on shaft 44 which shaft 44 has bevel gear 45 thereon meshing with bevel gear 46 on the upper end of motor shaft 4'7. Window sash 22 on its side portion has cavities 50 in which worm shafts 28' and 25 operate and window sash 35 has a cavity 51 on each shafts 39 and 38 side thereof in which threaded operate.

When it is desired to raise one of the sash its controlling switch is pushed upwardly and the sash is raised time the switch the desired distance at which is moved to neutral position, and

of course, in the lowering operation the switch is moved downwardly until the sash is lowered at which time the tion.

switch is moved to neutral posi- In the drawing and specification there has been set forth a preferred embodiment of the inven-' tion and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being set forth in the appended claims.

I claim:

posed shaft mo said vertically unted above the upper ends of disposed shafts and having a grooves, the pair of rods for one sash extending above the upper end of the sash, a transversely disposed rod having geared connection with said first pair of vertically disposed shafts and a motor having geared connections with said transversely disposed shaft, a second set of vertically disposed threaded shafts having threaded engagement with projections in the lower sash, a transversely disposed shaft having geared connections with said second set of vertically disposed shafts, and a motor for imparting rotation to said second set of transversely disposed shafts.
