The foregoing and other objects will appear from the description of the invention which consists of certain novel details of construction and combinations of parts hereinafter described and claimed.

In the drawing:

FIG. 1 is a front elevational view, partly in section, illustrating a window unit with sliding window sashes, equipped with the mechanism of a device constructed in accordance with the invention," the cover trim members of the device being removed.

FIG. 2 is a sectional view taken on line 2-2 of FIG. 1.

FIG. 3 is a sectional view taken on line 33 of FIG. 6.

FIG. 4 is a perspective view of a threaded bracket member of the device.

FIG. 5 is a perspective view of the end gear box member of the device.

FIG. 6 is a frontal elevational view of the same window unit, showing the cover trim members in place.

FIG. 7 is a perspective view of the one-piece center gear box member of the device.

FIG; 8 is a plan view of the sheet 'piece from which said center gear box is made. p

The double-hung window unit is shown as having a front and lower sash 1 with a glass pane 1g, and an upper sash 2 with a glass pane 2g; each sash being in sash channels in window frame 3. The channels are provided by the usual arrangement of stops or guide strips shown as

front stops

6a, 6b, central stops 7a, 7b and rear stops 8a, 8b. The window unit also includes a stool 4 and easing trim 5.

Mounted on the top of stool 4 intermediate the ends thereof is a gear box 90. A gear arrangement 9 in gear box 90 has bevel gears 9a and 9b, each with ten teeth, driven by bevel gear 90 which has twenty teeth. On top of 'the stool, at each end thereof, attached to the front stop,

is an end gear box. At one end, against front'stop 6a, is gear box 10a housing mitre bevel gears 11, 12, each having twelve teeth; and at the other end, against front stop 6b, is gear box 10b housing

mitre bevel gears

13, 14, each having twelve teeth.

A horizontal shaft 20, made up of shaft portions a, 20b, 20c, 20x, 20y, and

couplings

21, 22, carries gears 9a, 9b and gears 11 and 13.

Gears

12 and 14 are mounted respectively on the lower ends of vertically extending threaded shafts 15a, 15b respectively.

Attachd to the front face of lower sash 1 are threaded brackets 16a, 16b which threadingly engage threaded shafts 15a, 151) respectively.

The upper ends of threaded shafts 15a, 15b are journaled in fixtures 17a, 17b respectively, which fixtures are secured to

front stops

6a, 6b respectively, projecting out therefrom in front of lower sash 1.

Gear 9c is driven by a crank C which fits a crank slot CS in the shank of gear 90.

Lower sash 1 may thus be raised and lowered by the turning of crank C. The crank drives gear 90, which through gears 9a and 9b rotates shaft 20; the shaft 20 through gears 11, 13 drives the

gears

12 and 14 to thereby rotate threaded shafts 15a, 15b and drive threaded brackets 16a, 16b thereon either up or down to thus either raise or lower the window sash 1.

The working mechanism is hidden from view by cover trim members. The horizontal shaft 20 and the gear boxes and associated gears are hidden by L-shaped

cover trim members

30a, 30b and 30c; the center member 30c receiving the

members

30a, 30b telescopically to enable easy adjustment to different window widths. The vertical shafts 15a, 15b, the threaded brackets 16a, 16b and the journal fixtures 17a, 17b are hidden by L-shaped cover trim members 30cm and 3011b.

Each of the threaded brackets, as shown in FIG. 4, may be easily, economically and advantageously made from one piece by bending a thin steel strip into an L- shaped bracket with one leg three layers thick, as shown, and forming threaded opening 163 through the three layer portion.

Mounting holes

161, 162 extend through the other portion.

Each end gear box, as shown in FIG. 5, may be easily, economically and advantageously formed from one-piece 'by: bending a thin steel strip into the b or d shape shown with the extending leg two layers thick; forming

journal holes

103, 104 and 105 therein as shown; and forming

mounting holes

101, 102 through the two layer legs as shown.

Journal holes

104 and 105 are aligned, and rereive horizontal shaft 20 therethrough; the box thereby supporting and journaling the shaft. Shaft portion 20a is supported and journaled in box 10a. Shaft portion 20b is supported and journaled in box 10b. Hole 103 receives the lower end of one of the vertical threaded shafts on i which, inside the box, is mounted its bevel gear.v

The central gear box 90, shown in perspective in FIG. 7, may be easily, economically and advantageously made by bending from a pre-cut one-piece sheet of thin steel. In FIG. 8 is shown the piece from which the box is made, the dashed lines indicating where bends are made.

Box is formed with three walls parallel to the window panes; these three walls being: a front wall FW; a back wall BW; and an inner wall IW spaced from and intermediate said front and back walls. A top T is normal to and joins wall FW and wall IW at the generally forward portion of the box, and a pair of end walls EW and EW stand normal to both said top T and said walls FW and 1W. At the generally rearward portion of the box there is: at one end thereof, a two-layer end wall made up of walls EW and EW at the other end thereof, a

two layer end wall made up of walls EW and EW and spaced from said end walls and from each other are center walls CW and CW standing parallel to said end walls. Joining wall CW and wall EW is a bottom B and joining wall CW and wall EW is a bottom B Aligned openings H and H in front wall FW and inner wall 1W, respectively, receive the front and larger shank of the driving gear 90, said shank being thereby journaled and supported in the box. Openings H in back wall BW is smaller than and aligned with said openings H, and H and receives the smaller shank of driving gear 90 to thereby journal and support said shank in the box. Openings H H H in walls EWn, EW and CW respectively, and openings H H and H in walls CW EW and EW respectively, are aligned and are of equal size, and receive the horizontal shaft therein. Walls EW EW and CW support and journal shaft portion 20 For conveniently mounting .box 90 on the stool 4, two

screw holes SH are provided in top T, and a screw hole SH is provided in each of the bottoms B and B It has been found that steel rod of one-quarter of an inch diameter is excellent for

shaft portions

20a, 20b, 20c, 20x and 20y; and that sheet steel of about 18 guage is excellent for the gear boxes a, 10b, and 90, as well for threaded brackets 16a, 16b and journal fixtures 17a, 17b. The

cover members

30a, 30b, 30c, 3012a, and 30191) are made of sheet steel of about 26 gauge. The vertical threaded shafts a, 15b are three-eighths of an inch in diameter with 16 threads to the inch, triple lead; and the threaded openings in brackets 16a, 16b of course have matching threads. Gear 9c is about one and one-sixteenth inches in diameter. Gears 9a, 9b are about one-half inch in diameter, and the

gears

11, 12, 13, 14 are about eleven sixteenths inch in diameter. V

This window sash operating and holding device is easy to install in any double hung window in existing'buildings or in new construction. The gears and shaft portions are assembled with their associated boxes; then the end boxes are merely placed on the stool and screwed to the front stops, as shown. The central box 90 is then placed on the stool up against one of the end boxes and screwed to the stool. Shaft portion 20c is then selected, or cut, to the proper length to adjust for any variation in width, and assembled with

couplings

21, 22 to the shaft portions 20b and 20x. Fixtures 17a, 17b are screwed to the front stops, and the threaded brackets 16a, 16b are screwed to the sash l. The cover trim members are then merely screwed into place;

members

30a, 30b and 300 to the stool, and members 30m: and 3017b to the front stops. The entire device is thus easily installed and is very attractive. It has'all working mechanism hidden from view; but provides easy access thereto for any repair or maintenance. The entire working mechanism is above the stool, between the front stops, and out in front of the lower and front sash in extremely convenient location. The crank slot is above and close to the stool, and ofi to one side of the center of the stool, and is thus .very

advantageously located for the convenience of the operatoi'. The device operates quietly, easily and smoothly, without binding, in opening and closing the sash. It holds the window'strongly in any position, thereby providing security against forced entry from the back side, i.e., from the outside or exterior.
