  • Patent number: 3969136
    Abstract: Apparatus for treating cup-shaped workpieces in which the workpieces are positioned within a shape-conforming chamber formed with an outlet port in the base thereof and a conforming nozzle is positioned within the interior of the workpiece in close clearance-spaced relationship. The nozzle is provided with an axial port for discharging a high-pressure treating fluid against the central portion of the interior bottom surface of the workpiece, causing a high-speed radial outward flow therealong and thence axially outwardly along the interior wall surfaces of the workpiece. Upon reaching the open end of the workpiece, the direction of flow is reversed and is directed axially along the exterior wall surface of the workpiece, and upon passing the bottom edge thereof, the fluid is deflected in impinging relationship against the outer bottom surface, whereafter it is discharged through the outlet port and is recovered for reuse.

  • Patent number: RE31203
    Abstract: Apparatus for cleaning open-mouthed cylindrical containers has a plurality of pot assemblies mounted on a turntable rotatable to move each pot assembly past an unloading station for discharge of containers from the pot assemblies and a loading station for insertion of containers into the pot assemblies. Each pot assembly comprises a body co-operating with a lid to define a cavity for reception of a container, the cavity having a shape corresponding approximately to that of the container and having a size such that the container subdivides the cavity into two chambers in which the walls of the cavity are spaced close to the inside and outside surfaces of the container. Cam rollers on each pot assembly co-operate with cam tracks, upon rotation of the turntable, to open the lid immediately prior to passage past the unloading station and to close the lid immediately after passage past the loading station.
