WINDOW REGULATOR.

Application filed June 28, 1923. Serial No. 648,364.

" p This invention relates to a mechanism for raising and lowering windows, such mechanism being commonly known as window regulators, and, the object of my invention is the provision of a mechanism of the character described which is simple and inexpensive in its construction, is positive in operation, is easily operated to raise or lower the associated window, and is particularly adapted for use in connection with the type of windows commonlyrused in closed automobiles and other vehicles, which windows have lowering movements when being opened.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings in which,-

' Fig. 1 is an outer side elevation of the lower portion of an'automobile door with part of the sheathing broken away to show the invention associated therewith and also showing the window in lowered position.

Fig. 2 is an enlarged. fragmentary vertical sectional view of the door shown in Fig. 1 with the window in raised position.

Fig. 3 is an enlarged fragmentary sectional view showing the construction at the lower end of the worm shaft.

Fig. 4 is an enlarged fragmentary sectronal View of the mechanism at the upper end of the worm shaft including the operating handle, gears for turning the worm shaft,

, and co-operating-mechanism.

-Fig. 5 is an enlarged sectional view show ing the lower edge of the window in raised position, the window opening and associated parts.

Fig. 6 is a section taken on the line 66 of-Fig. 1 and shows the means for holding the worm and worm wheel sector in alignment,

Referring to the drawings, 1 is an automobile door having a window opening 2 therein, and 3 designates a glass orwindowpart which is adapted to be raised in position to close the opening 2 or to be lowered into the lower portion of the door, which is made hollow for such purpose, as is customary in doors used in closed vehicles, as for instance, in automobiles. r

The window or member 8 is adapted to rest freely at its lower edge on a roller 4:, which is carried at the freeend of a vertically swinging arm 5. The arm 5 is fastened adjacent to its lower end to a segment 6 of a worm wheel, the segment 6 and the arm 5 being pivoted at 7, to a metal board 8 which extends substantially across the full width of the door 1 and forms a part thereof for strengthening the same and entirely supporting the window regulator mechanism.

worm 9 formed on a vertical shaft 10 meshes with the segment 6. The lower end of the shaft 10 may be journaled in a bracket 11 which is secured by thev screws 12 to the lower flanged edge of the metal board 8. A ball thrust bearing 13 is also provided as a seat for the shaft 6 to take the downward thrust thereof, and a screw plug 14 threadedv in the bracket 11 is to adjust the axial position of. the shaft 10. The upper end of the shaft 10 ward thrust of the shaft 10. The member 15 may have a flange 18 which is adapted to bear against the inner surface ofthe metal board -8. The end of the member 15 adjacent the flange 18 projects through the board 8 and is recessed and threaded within the recess for a purpose hereinafter described. A. nut or clamping member 19 whose outwardly projectingiflange 20 serves as an escutcheon plate for holding the upholstering material 21-against the board 8, has a projecting threaded portion adapted to be threaded into the: threaded end of the member 15 and thereby clamp the metal board 8 and the upholstering material 21 between the flanges 18 and 20 and also firmly secure the member 15 in. place on the metal board 8. The nut or clamping member 19 has a central opening therethrough which serves as a journal and support for the horizontal shaft 16 which projects through the same and to which the handle 22 is suitably secured. A bevel gear 23, preferably of thespiral tooth type, is secured to the end of the horizontal shaft 16 opposite the handle 22 to turn therewith and also bear against the end of the member 15.

A flange 24 on the horizontal shaft16 seats against the bottom of the'recess in the end of the member 15 and this in conjunction with the gear 23 prevents longitudinal movement of the horizontal shaft16. A bevel gear 25 secured tothe shaft 10 adjacent its upper end meshes with the gear 23 and is caused to turn therewith to operate the 22 is turned, causing the worm. 9 to turn therewith, the worm wheel sector 6 is caused to rotate about its pivot 7 in a direction dependant upon' the direction of rotation of the handle 22. Inasmuch as the arm 5 is secured to the worm wheel sector 6, rotation of the handle causes the free end of the arm 5 to be raised or lowered, and the associated window, 3 resting on the roller 4 is caused to move up or down in a corresponding manner. A coil spring 26 attached 'at one end to the upper flanged edge of the metal board 8 and at the other end to the 511111'5 serves tocounter-balancethe weight of the window 3 resting on the roller 4 at the outer end of the arm 5', so that any strain due to the total weight of the window will be reduced and.

the' mechanism will work freely and without friction.

, The glass of the window 3 is provided with a channel shaped metal binding strip 27 at its lower edge which rests on the roller ii: of

the arm 5. The upper outside edge of this strip 27 being flanged over and outwardly as at 28. The sheathing of the door 1 pro jects over the lower edge of the window opening2 to a point adjacent the window 3 as. at 29 and is then turned back on itself fora short distance and a flexible rubber strip 30 is placed beneath the same. When the window 3 is raised the rubber strip 30 is compressed between the flange 28 and the door sheathing at 29, to prevent water from passing from the outside of the window to the recess or pocket formed for the winoow and thus prevent damage to the window regulating mechanism.

A downwardly projecting member 31 having aninwardly turned flange at its lower edge is fastened to the binding strip 27, the inwardly turned flange passing below the roller 4: on the arm 5 so that in the event the window 3 becomes stuck or does not freely follow the roller 4: when the same is lowered, the roller t will bear against the inwardly turned flange of the member 31 andpull the window 3 with it to its lowered position.

The segment of the worm wheel '6 as shown in the drawings is preferably made of sheet metal to reduce weight and cost and in the event that the window 3 works rather hard in its guideways the segment 6 might bend out of the engagement with the worm 9 when an excessive strain is put on the mechanism to move the window 3 if means was not provided (see Fig. for keeping the sector 6 and worm '9 at all times in proper alignment. This means comprises a block 32 secured to the metal board 8 in 'which is supp rted a ball-bearing 33 which bears against the side of the sector 6 adjacent its and over the outer edge of the sector 6 and c "ries a ball-bearing which seats freely between the member 3st and the sector 6 at Joint oii'the oppositeside of the sector 6 from the ball-bearing 33 but in a position corresponding therewith. The sector 6 is thus guided between the ball-

bearings

33 and 35 which prevents it from bending sidewise out of engagement with the worm 9. The arm 5 which is secured at its one end to the sector 6 to pivot therewith at 7, has its free end offset from the sector 6 so thatv upon rotation the arm will free the

ball bearings

33 and 35 and the guide member is raised to closed 34: when the window 0 position.

It has heretofore been common practice in building window regulators to provide means for loclzing the operating handle against rotation when not being operated, to prevent the window from slipping down inadvertntly. in important result olitainedby the do away with such locking mechanism as it' is an inherent characteristic of a worm and 'wheel that the wheel is self locking when construction shown is that it is possible to.

locking device may be used for preventing,

the window from working down.

It is understood that formal changes may be made in the specific embodiment of this invention without departing from the spirit or substance of the broad invention, the scope of which is commensurate with the appended claims.
