The cone has four grades, for 1½-inch belt; the spindle has extra large bearings, in gun-metal boxes, and has a hole through its center 3/8 inch in diameter. The boxes are seated in tapering recesses, and are split, so that ordinary wear may be taken up by means of cap-nuts. The cap-nuts contain felt-linings to prevent the introduction of dust, or of emery, when the lathe is used for polishing. A hand-lever for actuating the foot-stock spindle is furnished, in addition to the hand-wheel and screw, or without hand-wheel and screw, at an extra price. Lathe with 30-inch bed receives 12 inches between centers, and weighs. with countershaft, 360 pounds. Speed of countershaft, with 7x2¼-inch tight and loose pulleys, 320 revolutions per minute. |
