.~.~> In response to movement or position (e.g., limit of travel) of motor or driven device
DEFINITION
Classification: 318/281
(under subclass 280) Subject matter in which means are provided for repeatedly reversing the direction of operation of the motor in accordance with the schedule of operation of a continuously operating controller.
(1) Note. Means which operate to cause a motor to operate in one direction or another depending on a change in a condition, and in which the change may or may not occur, are not included herein. However, reversing means actuated repeatedly by a continuously running motor or a timing mechanism are included. The periodicity of reversal need not be regular, i.e., not as uniformly spaced periods of time.
SEE OR SEARCH THIS CLASS, SUBCLASS:
119, for reciprocating or oscillating motor systems having motors which periodically reverse their directions of operation.
443, and the subclasses specified in the Notes thereto, for other motor systems having periodically actuated motor control means.
