DEFINITION

Classification: 483/9

Identifying information on tool or tool holder:

(under subclass 8) Apparatus wherein the implement, a portion thereof, or member, e.g., an adapter, permanently attached thereto comprises the means which distinguish.

(1) Note. For an adapter to be "permanently attached" to the implement the apparatus must have no structure for separating the adapter from the implement.

SEE OR SEARCH THIS CLASS, SUBCLASS:

10, for apparatus wherein the detector monitors the implement, per se, or a particular feature of the implement, e.g., wear. When a particular feature of the implement such as diameter is monitored to determine the identity of the implement (e.g., to distinguish a one inch diameter from a two inch diameter implement) classification is proper in subclasses 8+. When the particular feature is monitored to determine whether it is within acceptable limits for a known implement classification is proper in subclass 10.
