DEFINITION

Classification: 254/363

Drive includes contacting friction wheels having noncollinear axes of rotation:

(under subclass 266) Apparatus wherein the drive includes two or more wheels which have (a) their axes of rotation not forming segments at the same line, and (b) their circumferences in contact with each other when transmitting power to the drum, the surface friction created by the contact of the wheels is solely relied upon for the transmitting of rotary motion from one wheel to another wheel.
