DEFINITION

Classification: 192/70.14

(under subclass 70.11) Device having a distinctive, structurally-significant peculiarity in the engaging face of the member.

(1) Note. Terms such as "segmented", or "faced with leather", or "roughened" or "tapered" are considered to be structurally-significant descriptors of the engaging surface. Functional terms such as "friction surface" are not proper for this subclass (70.14), and clutch-elements so described will be found elsewhere according to their other characteristics.

(2) Note. Compare this subclass (70.14) with subclass 107 of this class (192). A device in this subclass (70.14) relates to a clutch-element clearly identifiable as part of an

opposed-element clutch-assemblage, whereas a device of subclass 107 relates to the engaging face of an element, per se, usable in a clutch or brake.
