Abstract
4145. Brookes, A. G., [Dock, H.]. March 5. Tools and toolholders.-A tool and holder for cutting or chasing right or left hand screws, such as leading screws for lathes and milling or other machines, are mounted on the tool slide S of a lathe slide-rest. The circular tool 25 is pivoted on a slide 35, so that teeth of varying projections may be successively brought into operation. The slide 35 is mounted in a holder 41 secured to the tool slide S by a bolt 19, and capable of being tilted in either direction by a screw 29 to suit screws of either hand. The slide 35 is reciprocated by an eccentric pin passing freely through hub 49 carrying a hand-lever 40. The hub and pin are connected by a spring arm 62 secured to the pin and having a pin at its outer end which can be engaged with one of a number of holes 61 .in the hub, so that the forward movement of the slide may be regulated to suit successive teeth. The back stroke is limited by a stop 80. The tool is rotated during the back stroke by engaging a pawl 70, which is notched at its end to span and ride clear of the cutting-edges of the tooth during the idle stroke. The cutting-tooth is supported by a screw stop 76.
