Abstract:

A motorized implement having a housing containing a motor mounted therein the motor having a rotary shaft with an output end. The motorized implement further has a drive shaft with an input end pivotably supported relative to the housing and co-axially aligned with the rotary shaft. Moreover, the implement has a connector interposed between the motor and the drive shaft, which includes a pair of co-axial apertures, one to cooperate with the input end of the drive shaft to form a first connection. The other of the pair of apertures to cooperate with the output end of the rotary shaft to form a second connection. One of the first and second connections is securely fixed to its associated shaft end, and the other forms a pivotal universal joint. The aperture and associated shaft end which form the universal joint have corresponding non-circular cross-sections for enabling a slip-fit connection. The universal joint facilitates slight misalignment between the rotary shaft and the drive shaft.
