DEFINITION

Classification: 241/129

(under subclass 128) Apparatus in which the rotary motion of the plural surfaces centrifugally urges them toward contact with the common surface.

SEE OR SEARCH THIS CLASS, SUBCLASS:

122, for devices having these characteristics in which the common surface rotates about a horizontal axis.

131, for such devices in which the plural surfaces are not pivotally mounted.
