Click here for a printable version of this file

SECTION I - CLASS DEFINITION

This class provides for means for determining the characteristics and the mutual relation of points, lines, angles, surfaces, and solids, considered as having no properties but those arising from extension and difference of situation. It includes mechanically guided means for describing lines. Processes or methods are classified in the appropriate subclasses with instruments unless specifically provided for by a process subclass. For the most part specific subclasses are not provided for compound instruments; but an invention comprising matter classifiable in more than one specific subclass is placed in the subclass having the lowest number and cross-referenced into the subclass or subclasses having the higher number or numbers.

(1) Note. This class includes the combination of recording means with significant measuring structures of the type provided for in this class.

(2) Note. The following matter is excluded: The measurement of fluent material. Instruments falling in this class in combination with check-controlled means or in combination with a series of signals exceeding two. Observation instruments in which the principle of operation depends upon diverting light. Means for guiding or stopping tools other than scribers. Means for automatically assorting objects. Means connected with a device classifiable elsewhere to automatically indicate the relative position of movable parts of said device. (This does not refer to means connected with a device classifiable elsewhere to indicate the position of said device with relation to other things not a part of the device).
