ABSTRACT:
A control element for sensing the motion of a movable member within a machine to automatically prevent opening of a cover or guard on the machine when the member is moving. The control element has one of its ends brought into contact with a portion of the movable member and its other end connected to a latching mechanism located adjacent the machine cover. Being an elongated flexible member, the control element moves in response to the movement of the movable member. When the member is stationary, the end of the control element in contact with the movable member causes the control element to become an elongated rigid member to permit the latching mechanism to turn and allow the opening of the cover over the movable member. When the member is moving, the contact end of the control element adjacent the member is deflected, causing the other end of the control element connected to the latching mechanism to recede from its rigid position and preventing the movement of the latching mechanism to retain the cover in a locked position over the moving member.
