Abstract
An interlock for an eye setting machine insures the simultaneous presence of eye fasteners in each station of the eye setting press. Microswitch feeler elements at each station are connected in series with a relay coil. A normally closed contact of the relay is connected in a series circuit including a normally-open micro-switch, following a cam on the press, a solenoid for disengaging a clutch to stop the press from operating, and a normally closed manual pushbutton switch for overriding the interlock.
