DEFINITION

Classification: 74/11

(under the class definition) Devices comprising a subordinate power transmitting assembly, additional to and driven by one of the elements of a main power line, or by the prime mover therefor.

(1) Note. Power take offs from a prime mover for this class (74) are here unless they are made from a shaft extension of a prime mover, in which case, see this class, subclass 15.63. Take offs for engine accessory drives will be found in Class 123, Internal-Combustion Engines, subclass 198; take offs involving vehicle structure are found in Class 180, Motor Vehicles, subclasses 53.1+; and take offs for vehicle driven pumps are in Class 417, Pumps, subclasses 231+.
