Abstract
A safety mechanism for high-speed filling machines preventing accidental spilling in case of misalignment between a nozzle and the container into which it is to be lowered during filling; a safety arm which normally closes a switch is displaced by a nozzle in case the latter encounters an obstruction and moves relative to its nozzle holder after overcoming the restraining force of a releasable detent mechanism to thereby open the switch and therewith stop the filling operation.
