Abstract: AN APPARATUS FOR APPLYING AN IMPERVIOUS PROTECTIVE COATING OVER THE SEAMS OF CYLINDRICAL METAL CAN BODIES EITHER BEFORE OR AFTER THE SEAMS ARE WELDED, SOLDERED, OR CEMENTED AND PRIOR TO SPRAY COATING THECOMPLETE INTERIOR OF THE BODIES. THE APPARATUS IS OPERABLE TO INTERMITTENTLY APPLY AN AIRLESS SPRAY TO THE INTERIOR SEAMS OF THE CANS AS THEY CONTINUOUSLY MOVE PAST AN AIRLESS SPRAY GUN SECURED TO THE END OF A STUBHORN OF A CAN FORMING LINE. THE APPARATUS INCLUDES A NEW AND IMPROVED AIRLESS SPRAY NOZZLE WHICH IS OPERABLE TO ATOMIZE THE SPRAY NEARER THE NOZZLE THAN HAS HERETOFORE BEEN POSSIBLE. IT ALSO INCLUDES A PAIR OF AIR JETS LOCATED ON OPPOSITE SIDES OF THE SPRAY AND OPERABLE TO CONFINE THE ATOMIZED SPRAY OR FORG TO THE SEAM OF THE CAN SO THAT LITTLE OR NO EXCESS MATERIAL IS SPRAYED ONTO THAT PORTION OF THE CAN LOCATED ADJACENT THE SEAM.

Abstract: A double acting hydraulic pump and air motor therefor including means for controlling the inlet and exhaust of air to and from the opposite sides of the piston in the air cylinder. The pump has a stepped diameter housing including an upper pump cylinder defining an outlet chamber for liquid and a lower pump cylinder received within the upper pump cylinder and defining an inlet chamber for liquid. A pump piston reciprocates in the two cylinders and is slidably received in two axially spaced stationary packing sleeves having a resilient spacer sleeve interposed axially therebetween. The spacer sleeve is formed of metal sheet adapted to deflect resiliently under load. The upper end of the upper pump cylinder is received within a recess in the lower end of the air motor housing. A retainer plate connected to the lower end of the air motor housing is provided with an opening to allow passage of the upper end of the upper pump cylinder and a pair of radially extending ears thereon. The pump housing is rotatable about its own longitudinal axis to align or misalign the ears and the opening and retain the pump housing to or release it from the motor housing.

Abstract: An improved airless spray nozzle for spraying a fan or elliptically shaped pattern within which there is a predetermined uneven distribution of sprayed material. The nozzle has an orifice defined by the intersection of a single V-shaped cut through the end of the nozzle into an asymmetrically positioned conically shaped dome in the interior of the nozzle.

Abstract: A method and apparatus for applying an impervious protective coating over the seams of cylindrical metal can bodies either before or after the seams are welded, soldered, or cemented. The apparatus is operable to intermittently apply an airless spray to the interior overlapped seams of the cans as they continuously move past an airless spray gun secured to the end of a stubhorn of a can forming line. This apparatus includes an airless spray nozzle located on one side of the seams for directing a spray onto the inside corner of the seams of the formed can bodies and an air jet located on the opposite sides of the seams from the spray nozzle for confining the atomized spray or fog to the seam area of the can.

Abstract: An airless spray nozzle particularly adapted for coating the interior cylindrical surface of objects such as metal cans for food, beverages and other substances which need protection against injurious reaction with or pollution from contact with the material of the can. The nozzle has an orifice that produces a spray having an asymmetrical fan-shaped pattern so that the flow can be matched to the internal surface configuration of a can or similar cylindrical object to apply a uniform coating thereto.
