Abstract:
1. An apparatus for converting side-to-side substantially linear drive motion to rotational motion for a workpiece portion of an appliance, comprising: a movable base mounting element, capable of being driven in a side-to-side substantially linear reciprocal motion; a fixed position mounting element spaced apart from the base element, wherein the fixed mounting element is held in position so that it does not move during operation of the apparatus; a spring member connected to the movable base element and fixedly connected to the fixed mounting element; and a drive shaft member connected to the base element and rotatable relative to the fixed mounting element, the drive shaft having a workpiece mounted thereto; wherein the spring member is so configured and arranged that it is substantially less resistant to twisting action than to bending action, the twisting action producing workpiece rotation at a preselected frequency.
