DEFINITION
Classification: 84/341
Electric means for coupling parts of an organ.
(1) Note. Means for coupling two keyboards together are in this class, subclass 424. A simple type of rock-shaft for octave-couplers is common in reed-organs. (See particularly subclass 373). In pneumatic and electric organ-actions there is no sharp line of distinction between couplers and stop-actions, and in some modern constructions the old nomenclature is inapt.
(2) Note. See this class, subclasses 1.08, 235, 337, and 338.
