Motor dampening provisions are described. Incorporation and use of the motor dampener(s) in a rotary type drain cleaning machine enables elimination of a clutch in the machine. Also described are clutch-free drive systems using the motor dampener(s). Also described are torque countering members that are used in conjunction with the motor dampener(s).

An energy transmission control mount comprises a carrier having a first major surface, an opposite second major surface and an aperture provided therein. Channels are provided adjacent opposite ends of the first surface. Vibration dampening material is provided on the carrier. The vibration dampening material substantially lines the channels and the aperture and extends over at least a portion of the second surface.

Implementations described and claimed herein include a cushioning structure and method for manufacturing a cellular cushioning system, which allows for maximum comfort through the compression and shock cycle. Specifically, a cushioning structure comprises void cells formed in an array, which comprise multiple outwardly curved surfaces, with varying radius measurements. Stiffness in the void cells can vary by varying the radii. The outwardly curved surfaces prevent buckling and provide support for high impact by absorbing energy.
