Boring, Turning, and Slotting Mills With Two Heads Made by Pond Machine Tool Company. For boring and turning
pulleys, and doing all work usually done on a facing lathe, with the advantage
of ease in placing the work, inasmuch as the face plate being horizontal,
and by a single turn of a screw, convenient to workman, can be lifted off
the angular bearing at outer edge, work laid upon it may be moved about
until correctly centered, and then fastened. When boring small holes, or
turning small diameters, the plate may be lifted off the outer annular
bearing, as the spindle is very large in diameter and of great length,
and provided with a step at its lower end, upon which it revolves freely,
notwithstanding its extreme weight. Table is driven by means of cut spur
gearing. No bevel gears used, -- a very important feature, producing particularly
smooth work without jar or rattle, even at highest speeds.
Tool slides can be set at any angle by means of worm and ratchet provided, and are operated by friction feed, and so balanced, that, when feed is thrown out, they can be worked by quick hand movement easily. They are provided with four belts and two straps, and the table revolves in the direction that permits use of same tools as would be suitable for planers or large lathes. Feed, at any angle (up, down, or across), of one tool is independent of the other, and automatic; is operated by a disk driving a friction wheel, and can be instantly changed from 0 to 3/4 of an inch by moving the friction wheel from centre of the disk to the outer edge. For turning pulleys on
arbors, an equalizing driver plate, a saddle on cross rail fitted with
spindle, same as tail spindle of lathes, and a centre fitted into face
plate are furnished.
