Abstract

A water bath apparatus for testing pressurized cans of aerosol products in groups for leakers. A spokeless horizontal cylinder is supported and rotatable on trunnions in a tank partly filled with water. The cylinder has end rings which ride on sets of trunnions mounted on opposing walls on the tank interior. Uniformly spaced elongated clamps structurally interconnect the end rings to form the sidewall of the cylinder. Each clamp after loading carries a group of cans down into the water and then upwardly out of the water for unloading. A horizontal tube extends through the tank and through the spokeless interior of the cylinder. An elongated conveyor extends through the top of the tube and the interior of the cylinder. Each clamp is normally closed so as to retain a group of cans to be tested. Provision is made to rotate the cylinder in indexing steps so that as each clamp is sequentially indexed to a dwell position over the conveyor it is opened so as to allow the group of already tested cans therein to be conveyed out of the clamp and be replaced by an untested group whereupon the clamp is allowed to close.
