DEFINITION

Classification: 157/1.4

(under subclass 1.39) Devices in which the force-mechanisms are readily divisible into two categories; i.e., main and subsidiary.

(1) Note. The subsidiary mechanism is usually of a character different from and/or simpler than the main mechanism and can be operated for its purpose without substantially affecting the operation of the main mechanism. The disclosed purpose for the subsidiary mechanism is frequently the offsetting of the rim ends, while the main mechanism is usually disclosed as operating to expand or contract the rim.
