This invention relates to turning apparatus for turning articles, and in particular, to apparatus for turning articles to a predetermined diameter without the necessity for frequently stopping the machine to measure the diameter obtained. One object of this invention is to provide apparatus for use in turning machinery, such as lathes, this apparatus having provision for setting the cutting tool in a predetermined and known position relative to the turning axis so that the tool may be fed to a position giving a known diameter, without the necessity of measuring the diameter at intermediate stages. Another object is to provide a lathe carriage having devices for setting the cutting tool thereof at a predetermined and known distance from the axis of rotation of the lathe upon which the carriage is used, whereby the cross slide of the carriage may be moved transversely to a predetermined position by means of its micrometer dials, and thereby turn the work-piece to a known diameter without the necessity of measuring the diameter before taking the finishing cut. Another object is to provide a carriage for a lathe, wherein the cross slide Is provided with a micrometer adjustment for distance and the tool post has a reference face placed at a predetermined position relative to a reference mark, and a device for setting the cutting edge of the cutting tool on the axis of rotation of the lathe so that the cross slide may be moved forward or backward and returned to a definite position relative to the lathe axis, for producing work of a predetermined diameter without the necessity of intermediate calipering operations. Another object is to provide a lathe carriage having an adjustable device with movable stops operatively connected to the feeding mechanism so that work-pieces may be turned to successive stepped diameters without the necessity of intermediate calipering operations to determine the diameters reached during the turning operations. Another object is to provide a lathe carriage having adjustable devices for turning stepped work to predetermined diameters, these adjustable devices including a shaft operatively connected to the cross slide screw shaft and having a dog adapted to engage adjustable dogs arranged adjacent the shaft, these dogs being adjusted to be engaged by the shaft dog when the cutting tool has reached the limit of its feeding motion for producing the desired diameter of work.
