DEFINITION

Classification: 242/343.1

Yieldable brake:

(under subclass 343) Subject matter wherein the cartridge is provided with means for retarding: (a) rotation of a spool, or (b) longitudinal movement of the carrier.

(1) Note. The means for retarding must allow slippage between itself and the spool or carrier on which it acts as contrasted with a positive brake.
