Abstract

574,867. Drawing. ACCLES & POLLOCK, Ltd., and HACKETT, W. W. June 14, 1941, No. 7562. [Class 83 (iv)] Tubes to be rifled, fluted, ridged or otherwise profiled in a manner that permits separation from the mandrel, are mounted on a profiled mandrel a and pushed through a die h, the abutment b being able to pass into the die and the end being concave to prevent expansion of the upper end of the tube. The mandrel is grooved at f for retention in the abutment during the initial stage of the operation, by spring-pressed balls d, which permit release to accommodate the extension of the tube. If the machine works horizontally or inverted, the ball detent device is not required. Specification 130,336, [Class 83 (iv)], is referred to.
