WINDOW SASH ADJUSTING AND HOLDING DEVICE Filed May 31, 1949 Patented Jan. 16, 1951 ENT OFFlCZE WINDOW SASH ADJUSTING AND HOLDING DEVICE Charles J. Boos, Muskegon, Mich.

Application May 31, 1949, Serial No. 96,213

1 Claim. 1

This invention relates to a window sash operating and holding mechanism, the primary object of the invention being to provide an operating or adjusting mechanism designed for use on heavy window sashes, which can be controlled and operated with the minimum amount of exertion on the part of the operator.

An important object of the invention is to provide an adjusting and holding mechanism for window sashes, wherein the adjusting or operating mechanism will act as a holding means after the desired adjustment has been made.

Another important object of the invention is to provide means for retarding and regulating the downward movement of the sashes to prevent breakage and damage to the sashes, due to an overbalanced sash.

Another object of the invention is to provide a sliding window sash operator, in which the pressure applied for moving the sashes of the window to their adjusted positions, will be equalized at both sides of the window sashes, to eliminate binding of the window sashes within their frames, which binding action usually renders the operation of the sash diificult.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing:

plates l I that are secured to the opposite surfaces of the side .rails, the rack bars 8 and plates ll providing the sides of the vertical channels in which the pinions l2 operate. These pinions l2 are secured to the shaft I3, and have their ends mounted in the bearing plates I4 and I5. Se

cured to the shafts l3 are pinions l6 that are engaged by the worm gears H, which in turn are formed on the shafts I8 that extend through the side members of the window frame in which the sashes operate, the shafts It being provided with handles 19 at their forward ends, whereby the shafts I 8 may be rotated. In operating these shafts l8, it is contemplated to operate the handles l9 at opposite sides of the sash simultaneously, thereby preventing binding of the sashes within their channels, due to the operating pressure being applied at only one side of the sash.

In the form of the invention as illustrated by Fig. of the drawings, the

sashes

20 and 2| are provided with channel bars 22 fitted over the side edges thereof, the channel bars being provided with the racks 23, that are engaged by the pinions 24 secured to the shafts 25 that extend horizontally through the window frame at the center of the window, the shafts 25 being provided with gear 26 which are engaged by the worm gears 21 secured to the horizontal operating shafts 28 that extend through the window frame. Handles 29 are secured to the forwardly extended ends 30 of the shafts 28, so that rotary movement of the shafts 28 at opposite sides of the window, will operate the upper and lower window sashes simultaneously. It might be fur- Fig. 3 is a sectional view taken on line 3-3- of Fig. 2.

Fig. 4 is an elevational view illustrating a modified form of the invention, wherein a single operating shaft operates the inner and outer sashes of a window simultaneously.

Fig. 5 is a sectional view taken on line 5-5 of Fig. 4.

Fig. 6 is a sectional view taken on line 66 of Fig. 5.

Referring to the drawings in detail, the reference character 5 indicates a window frame which is provided with the usual sash channels, in which the lower sash 6 and upper sash I operate.

The sashes are provided with rack bars 8 that extend vertically, the rack bars being secured to the side rails 9 of the sashes, by means of the securing pins Ill, which pins also pass through the ther stated that the threads of theworm gears 2'! on each shaft 28, are disposed in opposite directions so that the shafts 25 are rotated in opposite directions to move one sash upwardly, while the other sash moves downwardly, the movements of the sashes being controlled by the direction of rotation of the handles 29.

From the foregoing it will be seen that due to the construction shown and described, I have provided a window sash operating mechanism specially designed for use with heavy windows.

Having thus described the invention, what is claimed is: e

The combination with sliding upper and lower sashes operating in window frames, of a sash operating mechanism comprising channel bars secured over the side edges of the sashes, teeth formed longitudinally and externally of the channel bars at one of their respective side portions, parallel shafts extending transversely of the sashes, pinions secured to said shafts, meshing with the teeth of the rack bars, gears mounted on the shafts spaced from the pinions, horizontally operating shafts supported within the window frame at opposite sides thereof, disposed at right angles to the parallel shafts, worm gears having REFERENCES CITED The following references are of record in the 10 file of this patent:
