Abstract: 333,973. Dunlop Rubber Co., Ltd., Willshaw, H., Goodhall, S. N., and Folliss, C. June 5, 1929. Coating-machines. -Apparatus for coating balls with paint or the like is characterized by the provision of means to perform automatically the whole or a part of an operative cycle including bringing the balls into contact with holders or grippers, gripping the balls, immersing them in paint, removing them from the paint, spinning them to remove surplus paint, and freeing them from the grippers. The apparatus comprises a framework 1 carrying guides 2 upon which slides a tray 3 bearing a platform 5 with anchorages 6 for the balls and a container 8 for paint; above the tray are grippers 10 carried by a head 11 mounted on a pivoted linkage 12, 13. In operation, the balls are placed by hand on the anchorages 6; the tray then slides in the direction of the arrow X until the balls are positioned directly beneath the grippers 10. The head 11 descends, and the grippers grip the balls, rise and remain elevated while the tray moves in the direction Y to bring the paint container under the grippers. The head descends, the balls are immersed and slowly rotated in the paint. The head rises slightly to bring the balls into cells 9 where they are spun rapidly to remove surplus paint. The head then rises further and the tray moves in the direction X again to bring the opening 7 under the grippers, which descend and deposite the balls on a continuous conveyer 17. The various motions are effected by cams driven by a motor 39; the tray is oscillated by a lever 45 pivoted at 46 and operated by cams; the head is raised and lowered by a lever 57, operated by a cam 58. The claws 21 of the grippers are opened and closed by a cam 69 which operates through levers 61, 62, 63, 65, 66 eccentrics 68 on a shaft 67; the eccentrics press against a plate 31 and depress rods 30, 28, which latter by moving collars 27 actuate the claws through short levers 22. The grippers are rotated through friction gearing 34 by a shaft 36 driven through belts 37, 76 from two pulleys 74, 75. The pulleys are driven at different speeds by the motor 39 through clutches 72, 73, operated by two face cams 78, 79, so arranged that one pulley is driven while the other is loose; by this means two alternative spinning speeds are imparted to the grippers. If desired a part of the operative cycle, for example the spinning of the balls, mav be controlled independently by a pedal, instead of by the motor driven cams. Specification 304,810 is referred to.
