Abstract: In a nutating action appliance including a motor housing and wobble plate arranged therein, a novel arrangement to divert a portion of the motive fluid to a motor-driven utilization device. The wobble plate includes an output rod which is connected to the utilization device. In accordance with the invention, a continuous fluid passage-forming means is provided in the output rod and utilization device and communicates with the main motive fluid supply line for the appliance. Discharge ports are arranged in the working end of the utilization device and are connected to the passage-forming means whereby a portion of the motive fluid is diverted from the main supply line directly to the working surface through the main functional components of the appliance. Provision may be made for a continuous or pulsating discharge of the fluid to the working surface.

Abstract: The disclosure relates to a power toothbrush or the like characterized particularly by the fact that the brush element is driven in an orbital path, as distinguished from a more conventional angularly reciprocating motion. To particular advantage, the power driven brush may be motivated by a water powered nutating action motor mounted in the handle of the unit, although alternative arrangements, including conventional electric motor units, may be used to power the device. In the preferred appliance, an orbital output motion of a nutating drive motor is converted to rotary motion, and this in turn is converted back to an orbital motion in the brush or working element. In other forms of the device, the orbital output of the nutating motor is imparted directly to the working element. The latter arrangement has advantages of greater simplicity, while the former arrangement has advantages of greater compactness.

Abstract: A lightweight, portable, fluid-driven orbital wet sander or the like comprising a fluid-driven, nutating action motor including a rod-like output element and a sanding or scrubbing device directly linked to a projecting end of the output element. The nutating action motor is mounted on a plate which includes a gripping element mounted on one side thereof to permit the sander to be easily held by the user. The sanding or scrubbing device is mounted in a spaced relation to the mounting plate by a transversely yieldable support means attached to and projecting from the side of the mounting plate opposite the handle side. The projecting end of the output element extends from the nutating motor through the spacing between the mounting plate and utilization device to a universal joint connection with the utilization device. The motor includes a housing confining a wobble plate which is driven with a nutating action by a controlled flow of fluid (typically water) through the housing.

Abstract: A portable, battery-operated manicuring machine is disclosed in which the batteries and the final output shaft are aligned substantially coaxially. The motor and actuating switch are positioned within the housing intermediate the battery chamber and the final drive unit with the motor being radially offset from the axis of alignment of the drive unit, batteries and housing and the switch being positioned diametrically opposite the motor. The drive between the motor and the final output shaft includes a gear reduction train comprising a pinion gear on the motor output shaft, a cluster gear having it's larger-diameter gear in meshing relationship with the pinion gear and its smaller gear in meshing relationship with an internally-toothed gear and the output shaft.The motor and gear-reduction train are mounted on opposite sides of a bulkhead which is mounted transversely within the forward part of the machine housing.
