DEFINITION

Classification: 141/140

(under subclass 138) Apparatus having a series of progressively acting heads and characterized by the fact that failure to provide a receiver at any given head inactivates that head for the particular cycle in which no receiver is supplied.

(1) Note. The charge intended for the receiver may either be retained in the supply system or diverted to another point, or other means may operate to prevent the formation of the charge.

(2) Note. In this subclass are those patents where the valve or trap is operated by contact with the receiver, there being obviously no operation of the valve or trap if there is no receiver present at the station.

(3) Note. Machines having this character of operation are known in the art as no-can-no-fill type.
