The invention relates to window regulators and has for one of its objects the provision of a simple construction of mounting for the irreversible drive mechanism and handle. Another object is to so construct the parts that one member forms the combined housing for the irreversible drive mechanism and the support for the escutcheon. A further object is to so construct-thismember that it may be cheaply manufactured and it and the associated parts may be readily assembled. With these as well as other objects in view, the invention resides in the novel features of construction and combinations and arrangements of parts as more fully hereinafter set forth.

In the drawing y Figure 1 is an interior side elevation of a window regulator embodying my invention;

Figures 2 and 3 are cross sections on the lines 2-2 and 3-3 of Figure 1;

Figures 4 and 5 are cross sections on the lines 4-4 and 5-5, respectively, of Figure'2.

As shown, the regulator embodying my in- I vention has the mounting plate 1, which is rigidly secured to an element, such as a lock board of a motor vehicle. 2 is the lifter element of the window regulator comprising the lifter arm 3 and the gear segment 4, the lifter arm having the pin 5 at its outer end for connection to the window and being rigidly secured at its inner end to the gear segment. This lifter element is pivotally mounted upon the mounting plate by means of the pivot 6, which is rigidly secured to the lifter element and is j ournaled in the mounting plate. 7 is the handle of the window regulator and 8 is the irreversible drive mechanism between the handle and the lifter element for actuating the latter from the former. The irreversible drive mechanism comprises the driving member 9 which is in the nature of a shaft having at one end the diverging wings 10 and at the other end the serrated portion 11 and intermediate these ends the cylindrical portion 12. 13 is the driven member of the irreversible drive mechanism having the diametrically opposite fingers 14, one of which is adapted to extend between the wings 10. This driven the portion 22 member is journaled upon the spindle .15 which is rigidly secured to the tongue .16 upon the mounting plate 1 and'eXt-ends axially into and forms a bearing for'the driving member 10. 17 is a pinionfsecured to and rotatable with the driven member 13 and. meshing with-the: gear segment '4 for driving the latter upon actuation of theformer.

18 is the'resilient' coil spring ofthe irre versible drive mechanism encircling the wings 10 and the fingers 14 and arranged to normally expand against a stationary memher to frictionally lock the parts in their various positions of rotative adjustment. This coilspring has the inturned ends 19 which are adapted to'extend between the wings 10 of the'driving member'andthe finger 14 of the driven member between these wings, the. arrangement being such that uponrotation of the driving member in opposite directions 79 the wings are alternatively engageable'with the inturned ends of the coil spring to con-. tract the same and releas/ethe look, after: which the engaged inturned end is forced into contact with the finger between the 7 wings and the driven member isrotated.

To provide a simple construction for mounting the handle and for engaging the coil spring'when expanded or in looking position, there is the drawn tubular sheet metal 39 member 20, which is formed with the annular flange 21 adapted to be rigidly secured to the mounting plate 1. This'tubular' member has for housing the irreversible drive mechanism and the portion 23 which is s5 internally threaded. Italso ha'sthe struclrout tongues 24 intermediate the

portions

22 and 23 and extending radially inward for abutting the cup-shaped washer 25 to position" the same. The cylindrical flange of this washer is adapted to engage the adjacent end convolution of the coil springlS to hold the latter from axial movement away from the mounting plate, while the web of this washer forms a bearing for the cylindrical portion 12 of the driving member. The internally threaded portion 23 is adapted to detachably engage the escutcheon 26, which forms abearing for the handle 7 and at the same time con-,

ceals the portion of the lining'surrounding 1 the tubular member 20. The escutcheon, which may be formed of one or more sections, threadedly engages the internally threaded portion 23 and has the handle 7 permanently rotatably secured thereto. The handle is provided with a serrated socket 27 for fitting the serrated end portion 11 of the driving member 10.

What I claim as my invention is:

' 1. In a window regulator, the combination with irreversible drive mechanism including a coil spring, a handle for actuating said mechanism and a bearing member for said handle, of a tubular sheet metal member common to both said mechanism and bearing member for housing said coil spring and frictionally engaging the same when in locking position and for detachably receiving said bearing member to support the same, said tubular member having struck-out tongues for positioning said mechanism.

2. In a window regulatonthe combination with irreversible drive mechanism including a coil spring, a handle for actuating said mechanism and an escutcheon member, of a tubular sheet metal member having a portion for housing said spring and frictionally engaging the same when expanded, a second portion for detachably receiving said escutcheon member to support the same and struckout tongues intermediate said portions, and an abutment member within said tubular member and positioned by said tongues for engaging an end convolution of said coil sprmg.

3. In a window regulator, the combination with irreversible drive mechanism, a handle for actuating said mechanism and a bearing member for said handle, of a sheet metal member having a portion for housing said mechanism and frictionally engaging the same, a'second portion for detachably supporting said bearing member and struck-out tongues intermediate said portions providing positioning means for said mechanism.

4. In a window regulator, the combination with a mounting plate, a handle, irreversible drive mechanism and a bearing for said handle, of a tubular sheet metal member secured to said plate having a portion for housing said mechanism and frictionally engaging the same, a second portion detachably supporting said bearing member and struck-out tongues intermediate said portions cooperating with said mounting plate to provide positioning means for said drive mechanism.

In testimony whereof I afiix my signature.
