ABSTRACT:
A peristaltic action pump filler includes a frame for supporting an elongate fill tube. A carriage member is mounted to the frame for reciprocating translation therealong. The carriage member includes a pair of pivotably mounted and oppositely disposed roller assemblies. The roller assemblies are interconnected to the carriage member such that, dependant upon the direction the carriage member is being translated, they are caused to pivot toward or away from the elongate fill tube which is supported therebetween. A valve mechanism is mounted to the support frame and coupled to fill the tube. The valve mechanism is interconnected to the carriage member so as to govern the amount of material discharged therefrom.
