DEFINITION

Classification: 318/371

(under subclass 370) Subject matter in which the plural braking means includes friction braking means combined with "plugging" and/or with dynamic braking.

(1) Note. For definition of "friction", "plugging", and "dynamic" braking, see definitions of subclasses 372, 373 and 375, respectively.

SEE OR SEARCH THIS CLASS, SUBCLASS:

372, for motor braking systems of the friction brake type.

373, for motor braking systems of the "plugging" or application of reverse power to the motor type.

375, for dynamic motor braking systems. SEE OR SEARCH CLASS

188, Brakes, appropriate subclasses, for the combination of diverse types of braking devices in general. Particularly note

159, wherein one form of braking means is actuated by current from a motor (acting as a generator) which also brakes by virtue of its dynamic action.
