Abstract: An indexing system for filling machines used to fill small containers transported on an endless conveyor belt, which includes a container-driven star-wheel, a member preventing the free rotation of the star-wheel and a cam-operated control for enabling and disabling the free, container-driven rotation of the star-wheel.

Abstract: An electric capping machine for crimping the caps of containers, in which each cycle of operation takes place fully automatically, once initiated by the operator; in the course of each operation, a container-receiving member is automatically raised into engagement with a spring-loaded abutment roller of the crimping mechanism which, upon further upward movement, causes the crimping roller to be positively brought into engagement with the edge of the cap by the use of a quadrilateral linkage connection actuated by a cam follower; to increase the safety to the operating personnel, both hands must be placed in a predetermined position relative to the machine before the cycle of operation can be initiated.
