DEFINITION

Classification: 234/108

(under subclass 107) Device wherein the means controls the application of electrical power to electromechanical transducers associated with the tool pairs to drive the same.

(1) Note. Fig. 21 illustrates circuitry and mechanism typical of this subclass. Depression of a key closes circuits to energize a group of tool-actuating solenoids.

(The lowermost key (D) is shown as controlling only one tool, but at least two other keys control distinct subgroups of the total number of tools, thus constituting combinational-coding-means* under the class definition).
