DEFINITION

Classification: 29/464

Associating parts by use of aligning means (e.g., use of a drift pin or a "fixture"):

(under subclass 428) Process in which adjunctive to the step of assembling of two or more parts (1) the relative position of the parts is compared with a separate standard or guide part and adjusted with relation thereto, or (2) one or more independent instrumentalities physically cooperates with the parts to actively register one with the other.

(1) Note. The aligning means of this subclass, especially under clause (1), may be inactive, i.e., it may serve to allow a user to visually align parts being assembled or, especially under clause (2), it may be active, e.g., it may be base mounted and guide one or more parts into assembled position or it may be manipulated by a user to position or align a part with respect to another part. If the aligning

means is base mounted, normally the parts are brought to it, whereas if it is manually manipulated, it is brought to the parts.
