DEFINITION

Classification: 192/215

TRANSMISSION AND BRAKE:

(under the class definition) Subject matter including a device that receives rotary input torque from a power source and transmits the torque to an output load, combined with a device to retard or stop rotation of the output load.

(1) Note. This subclass and indented subclasses are intended as the generic locus for combinations of torque transmitting devices and brakes not provided for elsewhere.

(2) Note. This class and indented subclasses do not include machines and instruments or apparatuses claimed as such, for which see the appropriate art classes. This class does not include the special tools, instruments, and subcombination peculiar to the special arts and provided for in the classification of the art classes.
