Those who are familiar with the instantaneous change gearengine lathe with the W. T. Emmes patent feed device, made byi he Cincinnati Lathe & Tool Company, Cincinnati, Ohio, willbe interested in a recently designed lathe with a new type ofpositive geared feed which that company has placed on the DIAGRAM OF POSITIVE FEED. market. The former design was of special value for screwcutting, as it was possible to obtain any one of forty positivechanges for that purpose by simply manipulating two knobs. The details of the new geared feed device are shown on thedrawing. The shaft M is connected to the spindle by a trainof gears. The bevel gear A, which is keyed to M, drives pinion B on shaft R, to which the worm C is keyed. Shaft R is sup-ported by the bracket, or arm G, which swings on the shaft can therefore be moved up and down by means of the handleN, thus making it possible to have worm C mesh with eitherone of the three gears D, E or F. The worm gears are shiftedby the fork T. Through the two pairs of gears I and J, andH and K, the three speeds at which it is possible to drive shaftS are doubled when transmitted to the feed rod, thus makingsix feeds available, which is all that are usually necessary ona 16-inch lathe for general manufacturing purposes. Twenty-two additional feed changes, ranging from
