(under the class definition) Device which comprises two or more distinct arrays of selectively controlled tools, or one array composed of distinct groups of tools controlled by separate tool selection mechanism.
(1) Note. A device in this subclass may consist of a plurality of virtually complete selective cutting machines interconnected to some degree as by control means or common drive means; or it may be in effect one cutting machine provided with distinct arrays of tools and conforming with the above definition.
(2) Note. The plural tool fields need not be spaced apart physically: tools of the several fields may be adjacent (or even intermingled) if there are distinct actuating means and/or distinct selecting means for each field.
(3) Note. The conventional Powers-type card punch, having a full bank of punch elements connectable column-by-column to a single input means (keyboard and pin-setting carriage) does not constitute a plural tool field selective punching device, for the selection means, as well as the actuating means is common to all columns of punches.
(4) Note. The addition of a second input means, such as a serial numbering attachment, to a selective punching device to control the punching in certain columns of a card will not
of itself effect patent placement in this subclass.
SEE OR SEARCH THIS CLASS, SUBCLASS: 38, for a combination of devices which may comprise plural tool fields, one of which is not selective.
