DESCRIPTION OF FOURTEEN-INCH GRINDING LATHE
This is a thoroughly universal tool. When not wanted for grinding, it can be used as a plain lathe with pulley feed. The live spindle is driven by a five-stepped cone for 24 inch belt. Front bearing is of hardened steel running in the best Babbitt metal. The tail stock is provided with means of setting-over, though the presence of an improved taper turning attachment renders this unnecessary, except to line the centre. The carriage is of the weighted variety, and has long composition guards to protect the ways from emery. For taper grinding or taper turning, the cross feed nut is attached to slide on taper bar. The power feed of carriage is by splined rod worm-wheel and the usual train of apron gearing engaging with a cut rack on side of bed. In grinding, a neat shipping device causes the splined rod to change its direction of revolution after the emery wheel has passed off the work ground at either end. The shipping dogs or stops are adjustable for any length of cut or position of work.
The grinding spindle revolves in dust-protected boxes on a bracket that may be swiveled into any angular position. The motion of the grinding spindle is obtained from a long overhead drum, driven from the main line independently of the main counter-shaft. A centre hole is bored in one end of the grinding spindle to receive an arbor for small emery wheels used in inside grinding. Two counter-shafts, back-rest, stationary-rest, tool post for turning soft work, wrenches, etc., are included. The speed of the main counter-shaft is 200, and of the drum counter-shaft, 300 turns per minute. The main tight and loose pulleys are 12 inches in diameter for 3 inch belt. The tight and loose pulleys on drum shaft are 6 inches diameter, for 2¼ inch belt. The shipping weight on a 6-foot bed is about 1,060 pounds. The lengths of beds and distances between centres are the same as for the standard 14- inch engine lathe.
