US Patent:

39380165, Feb 10, 1976
Filed:

Sep 18, 1974
Appl. No.:

5/506978
Inventors:

Henry James Lange - Juneau WI
Myron Lee McCunn - Horicon WI
Martin Adolph Berk - Horicon WI
Peter Jay Classen - Horicon WI
David Thomas Allen - Horicon WI
Assignee:

Deere & Company - Moline IL
International Classification:

G05B 1114
US Classification:

318467
Abstract:

A manually shiftable actuator-position input member and an actuator-operator feedback member cooperate as switch means for controlling the operation of an actuator including a rod connected to be reciprocably driven by a reversible electric motor. The input and feedback members normally occupy neutral positions relative to each other wherein electrical current is disconnected from the motor. Energization of the motor to cause it to drive in the forward and reverse directions may respectively be accomplished by moving the input member in opposite first and second directions from its neutral position. The distance through which the input member is moved preselects the distance through which the motor drives the rod, the motor driving the feedback member via the rod such as to restore the neutral positions of the input and feedback members when the rod has been driven to the preselected position.
