WINDOW REGULATOR..

Application filed March 25, 1927. Serial No. 178,203.

arms movable in unison to raise or lower the window. One or' the objects of the invention is to so construct the window regulator that it may be cheaply manufactured and assembled and easily operated to move the window through an extended range. Another object is to so construct the window regulator that the upper portion of the mounting plate may be secured to a lock board or other support or both its upper and lower ends may be secured to boards or supports. A further object is to so construct the window regulator that the pivotal means for the lifter arms may be located a substantial distance below the upper end of the mounting plate and the handle 0r crank for actuating the 2o mechanism may be located at the upper end of the mountingplate. 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.

ln the drawings Figure 1 is an interior side elevation partly broken away of a motor vehicle door having applied lthereto a window regulator embodying our invention; v

Figure 2 is an enlarged interior side elevation of the window regulator;

Figure 3 is an end View thereof;

Figures 4 and 5 are cross sections respectively on the lines 4-4 and 5--5 of Figure 2;

Figure 6 is a view similar to Figure 1 showing a modified arrangement. y

lin the present instance we have shown the window regulator embodying our invention as applied to a motor vehicle door having the vertically slidable window 1 in the nature of a glass adapted to close the opening 2 in the upper portion of the door or to be received in the chamber 3 in the lower portion of the door, the window slidably engaging in the usual guide ways. 4 and 5 are vertically extending spaced inner and outer mounting plates respectively` the outer mounting plate terminating short of the inner mounting plate and being rigidly secured at its upper end in spaced relation to the inner mounting plate by the shouldered spacer 6 having the lriveted ends 7. The lower end of the outer mounting plate Ais rigidly secured in spaced relation to the inner mounting plate by similar shouldered spacers 8 while the intermediate portions of the two mounting plates are rigidly secured in spaced relation by the similar shouldered spacers 9. The upper portion of the inner mounting plate is in the nature or' an anchoring portion, it being provided with the openings 10 for receiving screws or the like to secure the mounting plate to a lock board 11, as shown in Figure 1. The lower end of the mounting plate also forms another Vanchoring portion l2, it having openings 13 for receiving screws or the like to secure the lower end of the mounting plate to a board 14, as shown in Figure 6, `at which time the upper end of the mounting plate is secured to a board 15. This latter board may or may not be the lock board; The portion of the outer mounting plate 5 opposite the lowermost openings 10 in the inner mounting plate is provided with the aligned openings 16 to permit the insertion of the screws or the like as well as 'suitable operating tools therethrough While securing the inner mounting plate in place.

17 and 18 are the angularly movable lifter arms having their outer ends suitably operatively connected to the window and their inner ends rigidly secured to the

gear segments

19 and 20, respectively. 21 and 22 are the pivots for the lifter arms extending through the inner and

outer mounting plates

4 and 5, respectively, the gear segments 19 and 2O being rigidly secured respectively to these pivots. 'The inner ends or' the pivots are provided wth transverse slots 23 for receiving the innermost ends of the counterbalancing spiral springs 24, the outermost ends of which are provided with hook-s to engage the lugs 25 upon the inner mounting plate 4. The gear segments are located between the inner and outer mounting plates and in order to locate the pivots for the lifter arms adjacent to each other and at the same time provide for the necessary leverage to swing the lifter arms the gear segments are laterally offset and overlap each other.

To rotate the gear segments in unison, we have provided the vertically reciprocable rack member 26 located between the inner and outer mounting plates and having at its lower end the laterally odset

internal racks

27 and 28 facing each other and meshing respectively with the

gear segments

19 and 20. This rack member is provided at its upper end and along one of its edges with the external rack 29 extending parallel of the other racks and meshing with the pinion 30, whlch is rotated in unison with the gear 3l, the pinion and gear being mounted upon the shaft 32 extending between the inner and outer mounting plates. 33 is a second pinion meshing with the gear 3l and adapted to be driven from the driving shaft 34 through suitable clutch mechanism within the cup 35, the driving shaft having secured to its inner end the handle or crank 36. The cup 35 is rigidly secured to the inner mounting plate and as a consequence the driving shaft may be said to be mounted upon the inner mounting plate. Furthermore, the pinion 33 is mounted upon the pin 37 having one end mounted in the outer mounting plate and the other end mounted in the driving shaft and consequently upon the inner mounting plate.

The rack member 26 has the lower portions of its edges 26 below the external rack 29 slidably engageable with the shoulders spacers 8 and the pivots 2l and 22. For holding the external rack 29 in mesh with the pinion 30 there are the lugs 38 and 39 which are preferably struck out from the mounting plates and extend transversely thereof to engage the inner and outer edges of the rack member 26 facing in a direction opposite to that of the rack 29.

With the above construction it will be seen that the rack member is eectively guided during its reciprocation and that it simultaneous y actuates the gear segments and thereby swings the lifter arms in unison. It will also be seen that the handle or crank for actuating the mechanism is located at the upper end of the mounting plate, while the pivots for the lifter arms may be located near its lower end. It will be further seen that the construction is such that it provides for a very simple form of reduction gearing. In addition to these features and of decided importance is the fact that separate pivots are provided for the lifter -arms and arranged adjacent to each other.

What we claim as our invention is:
