First Claim
Patent Images
1. A vacuum cleaner comprising:
- a base assembly having a housing, a suction nozzle, and an agitator rotatably mounted to the housing;
a motor comprising a motor shaft;
an agitator drive assembly between the motor shaft and the agitator for selectively driving the agitator, and comprising;
a drive disk mounted to the motor shaft for rotation therewith and having a drive face;
a driven disk selectively coupled with the drive disk for rotational contact with the drive face of the drive disk; and
a drive coupling between the driven disk and the agitator;
a shaft pivotally coupled to the housing for rotation about an axis defined by the shaft;
an actuator operably coupling the driven disk with the shaft to move the driven disk about the axis defined by the shaft between an engaging position in which the driven disk is in rotational contact with the drive face and a disengaging position in which the driven disk is disengaged from rotational contact with the drive face; and
a speed selector assembly slidably coupling the driven disk to the shaft to allow the driven disk to slide substantially parallel to the axis defined by the shaft for lateral movement across the face of the drive disk to change the relative speed of the agitator.

Abstract
An upright vacuum cleaner comprises a base assembly pivotally connected to an upright assembly. The base assembly comprises an agitator and an agitator drive assembly for selectively driving the agitator. The agitator drive assembly includes a drive disk coupled to a motor shaft, a driven disk which engages the drive disk, and a drive coupling between the driven disk to the agitator. The agitator drive assembly can further include a drive disengager for selectively interrupting the transmission of drive force to the agitator. The agitator drive assembly can further include a speed selector for adjusting the relative speed of rotation of the agitator.
