DEFINITION

Classification: 112/465

Including plural, selectively used cams:

(under subclass 459) Devices including at least two first element cams, one of which can be chosen for active engagement by a slave element.

(1) Note. A first element cam is in "active" engagement with a slave element if cam movement causes movement of the slave element which in turn causes another functional element such as a needle movement or material transporting mechanism to move.

(2) Note. Devices having coaxial cams with cam portions which portions are adjustable relative to one another so as to define a single cam surface, which surface rotates to move a slave element and connected mechanism, are included in this subclass.
