A system for automatically dispensing metered amounts of viscous product in assembly-line fashion into each of a series of containers, wherein the temperature of the product is maintained within a preselected range along its path of flow. Structure is provided for substantially reducing product leakage along the path of flow, including a pneumatically actuated shut-off valve which operates in the nozzle in synchronism with each piston stroke. Structure is also provided for precisely adjusting the individual piston strokes.

A system for dispensing measured amounts of viscous liquid product into each of a series of containers which are progressively moved up to a filling station in assembly-line fashion, which system comprises in combination driving means and a supporting frame; a reservoir of the liquid product; at least one piston cyclically operated by said driving means in reciprocating slidable motion within a piston sleeve to provide in its retracted position a storage space for a quantity of said product, and in its closed position to discharge said quantity of product from said storage space; at least one nozzle assembly and a two way valve, operated by said driving means in synchronism with said piston, connected in a first position to receive said quantity of product discharged from the storage space in said piston sleeve, and to deliver said discharged quantity to said nozzle assembly for dispensing into each of the containers of said series, wherein each said piston consists essentially of a solid rod coaxially disposed in slidable relation in said piston sleeve; means for adjusting the stroke of each said piston in the corresponding said piston sleeve comprising a collar, having an outer annular face, disposed in fixed position relative to said supporting frame for supporting said piston in slidable relation to said collar; means slidably mounted on said piston adjacent the outer annular face of said collar comprising a nut having an axially disposed annular screw-threaded recess of a diameter slightly exceeding the diameter of said piston; and an annular lug secured to the surface of said piston having an axial screw-threadable nipple which is adjustable accommodated in the screw-threaded recess of said nut; a pusher bar longitudinally extended in a direction transverse to the axis of said piston, one end of said pusher bar being constructed to accommodate said piston in slidable relation; said pusher bar being secured to an inner face of said nut adjacent said collar, to facilitate fine screw adjustments between said nut and a lug secured to said piston.
