DEFINITION

Classification: 188/71.1

(under the class definition) Motion-retarding means wherein the motion to be retarded is rotation of a wheel, pulley, disc, or an analogous member rotating about an axis and having a radially-extending surface, and wherein said means includes a component with the following characteristics: (a) it is supported to be adjacent to said member, but substantially fixed against rotation therewith; (b) it has a friction surface complementary to said radially-extending surface, but normally spaced away therefrom; and (c) it may be moved in a direction parallel to said axis to effect mutual contact of the complementary surfaces, whereby upon occurrence of said contact, the rotation of said member will be retarded.

(1) Note. The term "radially-extending surface" includes a conical or frustro-conical surface as well as a planar surface that is perpendicular to the axis of rotation.

(2) Note. Patents in this subclass (71.1) usually claim a housing that supports a disc-brake assemblage, or the means for mounting such a housing, but omit structure that would justify placement into one of the indented subclasses.
