Abstract: A container filling machine is provided with easily demountable nozzles or valves capable of being clamped in position in openings through which fluid product passes from the reservoir to containers. Clamping assemblies, pivotable into engagement with flanges on the nozzles, are fixed to the machine between the nozzles and a single assembly either clamps two of the nozzles in operating position or frees them for removal.

Abstract: A valve mechanism for positive displacement, rotary receptacle filling machines having vertically movable valve stems operable by fixed cam tracks employs cam followers pivoted on the valve stems for movement in a vertical plane and horizontally settable means for locking them against such movement.

Abstract: A positive displacement rotary receptacle filling machine employs a receptacle detecting mechanism which detects the presence or absence of a receptacle in the file being fed to the machine at a point ahead of the filling position of such a receptacle and effects a presetting of the valve operating mechanism of such a machine at a point correspondingly ahead of the initial filling position, utilizing a settable trip shoe separate from the settable valve operating mechanisms of the machine for this purpose. The arrangement described results in a significant extension of the filling arc of the machine, making possible a corresponding significant increase in its speed.

Abstract: A pressure-actuated valve is adapted to the discharge port of a positive displacement machine for filling, sequentially, passing open containers with a liquid product. In response to the sequential pulses of liquid produced at the discharge port, the pressure-actuated valve opens and closes to deliver a predetermined amount of liquid to a waiting container. Even with low viscosity fluids, operation of the valve remains effective, permitting release of fluid during the delivery period yet preventing contaminating drips of fluid from the nozzle during non-delivery periods. Owing to the special valve design, delivery of accurate amounts of liquid and elimination of nozzle drip between container filling cycles are ensured, regardless of slowdown or interruption of machine operation. Contamination of the filling station resulting from product splash is also eliminated despite high speed operation of the machine.
