Abstract
367,503. Cupping. RHODES, C. J., Grove Iron Works, Wakefield, Yorkshire. Dec. 24, 1930, No. 38872. [Class 83 (iv).] In a double-acting cupping press the descent of the top die 5 in depressing the draw-ring 7 thereof moves the rack bars 17 downward, one rack 18 thereon raising the pivoted weights 29 which provides a constant resistance during drawing, the other racks 19 operating through sprockets 21 to raise the central rack 22 coupled to the lower die 25 which is raised thereby. The weights 29 also return the lower die and draw-ring 7 after drawing. The ascending ram also ensures this return by rods 39 coupled to the frame carrying the rack bars 17 and so pulling them up with itself. The weights 29 are adjustable on their levers. The lower rack teeth are held in working position against their pinions 21 by rollers 33 mounted between side plates 31, the roller spindles also carrying adjustable friction plates 33a bearing against the rack bars. An ejector 38 is provided.
