Application fled September 25,

nection to the window-and to the mem er 20. arm and also for actuating the lifter arna. Further objects are the provision of a window lifter of the screw drive ty e having an improved nut for connecting t e screw to the lifter having an improved universal coupling for rotating the screw.

With these as well as other objects in view, the invention resides in the novel features of construction an combinations and arrangements of parts as more fully hereinafter set forth.

In the drawings: Figure 1 is an inside elevation, partly broken away, of a vehicle door havin aplied thereto a window regulator em mg my invention;

igure 2 is a vertical section. therethrough; a

Figure 3 is a 111m view of the lifter arm;

Figures 4 am. 5 are inside elevations of the sections of the nut for connecting the screw to the lifter arm;

Figure 6 is a sectional elevation showing the universal coupling for connecting the screw to one .of the drive shafts and also showing the manner of securing one of the drive gears upon the latter shaft;

Figure 7 is a plan view of a blank'from which the mounting plate is formed.

In the present instance I have shown my window regulator as applied to the door 1 of a vehicle which has in its upper portion the o ning 2 and charm r 3. 4 is in its lower portion the the window or closure which is vertically slidable in the side uprights of the door from a position closing the opening 2 into the chamber 3.

' 5 is the mounting plate for the mechanism of the wind ow regulator, this mounting plate being a gusset extending across a cor- (1 channel 11 lifter arm.

being connected to the latter extending transversely of the rivets which connect the gear applied through the screws nae. Serial 1'... 789,887.

ner between one of the side uprights of the door and the lock board 6 and secured at its ends to this side upright and the lock board suitable means sucl l as the screws 7. is the lifter arm pivotally mounted at 9 upon the lower ortion of the mountin plate 5 and provi ed at its outer orfree end with the roller 10 which is engageable in the secured to and depending from the lower edge of the window. 12 is the screw for swingin the lifter arm, the threaded portion of this screw enga ing the nut 13 which is pivotally connecte to-the 14 is the gear box housing the

gears

15 and 16, the shaft of the former handle 17 upon the inner side of the door and the shaft of the shaft and being connected to the upper end of the screw 12 by the universal coupling 18. This gear box is formed in two sections having their meetin edges in the plane of the axis of the sha t carrying the gear 16 and the sections are secured together by box to the mounting plate. 19 is the window counterbalancing sprin having its lower end connectedto the lii ter arm 8 and its upper endadjustabl connected to 5 near tie upper end s' cificall shown the mounting plate is provided wit 1 the elongated o enings 20 which are alternatively engage-a le by the hook 21, which in turn is engageablc by the hook 22 secured to the upper end of the counter balancing spring.

23 is abumper formed of suitable material such as rubber and located upon the bottom sill of the door to engage the outer or'iree end of the lifter arm 8 when the latter is in its lowermost position. This bumper is so ositioned that the channel 11 upon the win ow clears the bumper and as a consequence the weight of the window remains upon the roller 10 of the arm.

As shown particularly in Figure 3, the lifter arm 8 is laterally bent near its pivotal end so that its pivotal portion 24, which is en ageable with the pivot 9, is in substantia alignment with the centers of the roller 10 and the nut 13 whereby when force is 12 to raise or of the lifter ath parallel le.

lower the lifter arm, tendency arm to turn laterally or in a to the axis of its pivot is negligi first fit by th The nut 13 is formed of the

sections

25 and 26 each having a pivot portion 27. The pivot portion of the section 25 is journeled in the lifter arm itself while the pivot portion of the section 26 is journaled in the bracket 28, the foot fl secured to the lifter arm such as rivets. 26, as shown particularly inFigures 5 have he same type all of which facilitates the assembly. To maintain t e sections in proper relation to t 1e screw 12 and at the same time to take care of wear of the screw threads there is t 10 spring washer 29 ocated between the ket 28 and the adjacent section 26 tend ing to section.

The hook end of the lignment with .lifter arm and t to centers of the nut and roller connected to the lifter arm whereby the force exerted e counterbalancing spring has no appreciable tendency to laterally turn the lifter arm,

As shown particularly in FigureG, the universal coupling 18 is formed of a section of rod, the end portions 30 and 31 of which are flattened at right angles to each other and respectively engage between the, bifurcations 32 and 33 of the shaft 34 and screw respectively. These fl may be more readereupon and WlllCll mg plate to a force this section toward the other t y ment.
