Abstract
An apparatus having a pivoted arm mounted on a base for seizing and releasing an article that is hinged at one end and which includes a control link that maintains a fixed length while the arm moves the article about its hinged end between preset positions, but changes its length and thereby provides a signal indicating that the arm has seized the article when the latter is moved in a direction opposite to the normal movement.
