Abstract

339,567. Hahn, H., Hahn, O., and Tessky, K., (trading as Index Werke, Halm & Kolb). March 1, 1929, [Convention date]. Tapping nuts.-In a curved-shank nut-tapping machine, resilient means are provided for preventing the last of the string of nuts from falling from. the tap before it is positively discharged by the freshly tapped nut. A spring-pressed plunger g may hold the nut resiliently on the tap a in the delivery channel b. In modification a resilient plate may replace the plunger, or the shank of the tap may have a different curvature from that of the chunnel b, or the channel may be slotted longitudinally at the outlet end, the diameter being reduced at the slotted part.
