manovermekanism for conversion of lines rorelse to reversible vridrorelse

摘要

An actuator for converting linear motion to alternating, opposite direction, rotary motion. The actuator is electrically operated and selectively activatable to produce rotary motion in a desired direction via separately incorporated electrical circuits. Included is an electric solenoid operated plunger which reciprocates a rotatable cam. The cam both drives a rotatable pivot member in alternating, opposite directions via cam followers and completes one or the other of two electrical circuits depending on the rotational position of the pivot member. The solenoid is activatable to produce rotational motion in a desired direction only if the cam is completing the appropriate electrical circuit. The cam is supported by a housing and is positioned for re-engagement with one of the pivot member cam followers by the housing after each stroke of the solenoid.
