Abstract

471,043. Screwing. POPPENSIEKER, F. April 3, 1937, No. 9528. [Class 83 (iii)] In a screw-thread-cutting machine the hollow spindle r carrying the cutting tool and moved axially by the thread cutting operation is coupled by a sleeve i with the driving shaft g keys k connecting the sleeve with grooves h in the shaft g and rollers v mounted on studs u fixed to the end of the hollow spindle r which is fitted with a strengthening collar t engaging slots q in an overhanging part of the sleeve i so as to transmit the drive from sleeve i to spindle r. During the idle approach of the tool to the work the sleeve i slides on the shaft g with sliding friction, but during the cutting operation the spindle moves forward relatively to the sleeve with rolling friction.
