DEFINITION

Classification: 234/94

(under the class definition) Device provided with mechanism to condition a plurality of tool pairs in response to an input-impulse.*

(1) Note. Tool acutation may follow as a result of selection, or may be effected by independent means (e.g., by hand lever) after one or more selections have been made.

(2) Note. Means to select a plurality of tool pairs in response to a single input-impulse constitutes a combinational-coding means*, as distinguished from means to produce a one-hole-(or positional) code.

(3) Note. For original placement in subclass 94, a patent must claim specific tool-selection mechanism, i.e., such mechanism must be recited in terms of structural relationships.

(4) Note. Fig. 18 illustrates a form of combinational-coding means wherein a coding memeber CSM is pivotally mounted to swing in either direction from its neutral position upon depression of either key K or K'. In either of its actuated positions, member CSM closes circuits to move interposers I to condition a group of tools (not shown) to perforate a

distinctive code symbol in a workpiece. [figure] [caption]Fig.18.COMBINATIONAL-CODIN- MEANS (subclass 94).
