WINDOW REGULATOR.

Application filed October 16, 1923. Serial No. 668,866.

To all whom it may concern:

Be it known that I, NORMAN MAXWELL WAGNER, a. subject of the King of Great Britain, and a resident of the village of Milverton, in the county of Perth, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Window Regulators, of which the following is the specification.

My invention relates to improvements in window regulators and the object of the invention is to devise a. simple and cheap construction of window regulator which will be positive in action and which will hold the window definitely at any point desired and it consists essentially of the arrangement and construction of parts as hereinafter more particularly explained.

Fig. 1 is a sectional view through an automobile door showing the window in the open position and my mechanism for operating the same.

Fig. 2 is an elevational view of the central portion of the door as shown in Figure l with the outside wall or plate removed.

Fig. 8 is a vertical sectional view through a fragmentary portion of the door showing the operating gears and handle.

In the drawings like characters of reference indicate corresponding parts in each figure.

1 indicates an automobile door, such door being hollow and provided with an inner wall 2 and an outer wall 3 and frame 4 in terposed between the outer and inner wall to space them apart. The upper member 4* of the frame 4 is provided with a slotted opening 4 for the passage of the window. 5 is the window. 6 is an orifice having an enlarged inner end 6 in the outer wall 3 of the door. The lower member of the frame 4 is providedwit-h a central recess 7", such recess being located in the inner edge of the frame so that the wall 2 also forms the inner wall of the recess. 8 is a plate member which is cut into substantially U-shaped form, the arms 8 and 8 of which are provided at their upper ends with out-turned portions 8 which extend over the upper edge of the wall 3 as indicated by dotted lines in Figure l and are secured to the upper edge of the wall by screws or other suitable means.

The plate 8 is provided with a depending bar member 9 extending downward to the lower member 7 of the door frame, the bar member 9 terminating in a tongue 9* fitting into the recess 7*. '10 are lazy tongs of the usual construction, the lower members 10 and 10 being pivoted together at 11 and to the inner wall 2 of the door. 'The upper members 12 and 13 of the lazy tongs are pivoted together at 14: and to a depending lug 15 of a bracket 16 in which is carried the window 5.. i

23 and 24: are bearings carried by the plate arms 8 and 8 of the plate 8. 25 is a drum journalled at its ends in the bearings 23 and 24:. 26 and 27 are cords which are reversely wound upon the drum 25 in proximity to each end thereof. 28 is a pulley wheel journalled upon the bar member 9 in proximity to its lower end. The cord 27 extends downward from the drum 25 and is directly connected to the pin 22 and the cord 26 passes around the pulley wheel 28 in opposite directions and then extends upward therefrom, their extreme end being secured to the projecting end of the pin 22. 29 is a worm wheel secured to the drum 25 at the outside of the bearing 24.

30 is a worm carried upon a short shaft 4-3 journalled in the plate 8, the worm 30' is in mesh with the worm wheel 29 and as such worm is rotated the drum 25 is turned thereby so as to wind one cord 26 or 27 upon such drum and to unwind the other cord. By this means it will be seen that an upward or downward pull is exerted upon the pin 22 to expand or contract the lazy tongs and thereby raise or lower the. window 7, the pin 22 being guided in a vertical slot 22*. In order to rotate the worm wheel 30 I provide the following mechanism which is located in the orifice 6 of the door hereinbefore referred to.

32 is an orifice formed in the plate 8. 33 is a covering plate secured to the outside of the wall 3 and covering the orifice 6. The plate 33 is provided with a central opening 34*.

423 is a shaft upon which is secured the worm 3O meshing with the gear 29. The outer end of the shaft 43 is threaded as in dicated at 455, an operating handle 46 being screwed .thereonto and secured in position by a set screw 47 bearing against a reduced portion 48 of the shaft 48, as is clearly indi cated in Figure 3. a, t y

By turning the handle 4:6, the shaft a3 is rotated, turning the worm 30 and the gear 29 in mesh with the gear 30 and thereby rotating the drum and alternately pulling upon the cords 26 and 27 to expand or contract the lazy tongs and raise and lower the window. It will also be seen that the window will be automatically locked in any position by the worm gear and worm, it being impossible to turn the worm by the worm gear.

From this description it will be seen that I have devised a very simple construction whereby a window of an automobile door may be raised or lowered to any desired position and held positively in such position so that it cannot be moved vtherefrom either by pressure or inadvertently by the vibration of the car.

What I claim as "my invention is:

In a window regulator, the combination with a pocketed door, of a supporting plate, the upper portion of which is U form, the central portion depending therefrom and embedded at its lower end in the door, bottom lugs extending inward from the upper end of the arms of the U adapted to b e secured at the upper edge of the door pocket, a roller journalled between the arms of the U so as to stand inwardly from the face thereof, a set of lazy tongs the lower membersof which are pivotally connected in proximity to the bottom of the supporting, plate, a pulley ,journalled on the connecting pin, a pin extending inward centrally from intermediate arms of the lazy tong, a flexible cord depending from such pin around the aforesaid pulley and then upward to oneend of the drum, and a flexible cord extending upward from the pin to the opposite end of the drum and reversely wound thereon to the aforesaid flexible cord, a worm wheel secured at one end of the drum, a shaft mounted in the upper end of the supporting plate adjacent the worm, a worm mounted upon the shaft engaging the worm wheel, and an operating handle detachably secured to the shaft at the outside .of the door pocket.
