A filling machine for dispensing sometimes viscous liquid in measured amounts to containers wherein a carrier supports a plurality of individual containers with open upper ends for lateral orbiting movement with a central tank, a pump and valve assembly orbits with the carrier and has a plurality of rotary valves, communicating with outward passages from the tank and with piston pumps, and also communicating the piston pumps with dispensing openings arranged above the containers. The pistons of the pumps are controlled by a pivotal cam track which can be swung to various positions to change the extent of the suction stroke of each piston, when operated by an actuating member. The machine is particularly designed for disassembly and for cleaning.

In a machine for dispensing liquid and semi-liquid material and the like in measured amounts to containers and having a supply tank with a plurality of circumferentially spaced radial tank outlet openings; a carrier for supporting a multiplicity of containers with open upper ends mounted for lateral orbiting movement with said tank; a filler pump and valve assembly, mounted to orbit with the carrier, and connected with said tank, the assembly having a plurality of passages communicating with the tank outlet openings, the assembly also having a plurality of separate pump communicating passages, and a plurality of separate dispensing openings disposed above the path of movement of the carrier and the containers thereon; the said passages being arranged in radially aligned sets, each having a tank outlet passage, a pump communicating passage, and a dispensing opening; said assembly also including a valve for each set with passage means in the valve in one position feeding material to the pump communicating opening from the tank outlet passage and in another position feeding material from the pump communicating opening to the dispensing opening; and a pump cylinder portion on said assembly for each passage set in communication with the pump communication opening of the set; each pump cylinder portion having a piston mounted for reciprocating movement in a suction and ejection stroke; arcuate cam track means about which the pump pistons orbit, the pistons being connected with followers moved by the cam track means to provide the stroke of the pistons and determine the amount of material moved by a pump piston out the dispensing opening of each set; the improvement wherein said frame has a sleeve, internally journaling a central shaft and externally journaling a cage hung from the upper part of said central shaft, the cage externally mounting the pistons for reciprocatory movement vertically and having a guide slot opposite each piston; guide means projects laterally from each piston and is receivable in one of said guide slots to prevent piston rotation; brace supports project radially from the tank assembly; said filler pump and valve assemblies have converging recesses at their sides permitting their suspension from a pair of said supports in a manner to be liftable vertically off the supports for individual cleaning; and means on said supports to individually releasably clamp said assemblies in place.
