Abstract

396,134. Drilling-machines. STEUDEL, W., 3, Sp÷rlstrasse, Gera, Germany. Feb. 22, 1932, No. 5231. [Class 83 (iii).] In a high-speed drilling-machine, a pinion 6 driven by a motor 16 or otherwise is mounted on a casing 15 eccentrically with regard to a turn-table 2 which carries a number of independent double gears 4, whereof the upper gears, on rotation of the turn-table about its centre, may be selectively engaged with the driving pinion 6 and the lower gears engaged with a driven pinion 7 on the drill spindle 5 to rotate the latter at a selected speed. The gears 4 are exchangeable with others of different size and their pivots 9 are adjustable along radial slots 8 in the turn-table. A hand operated pinion accessible from outside the casing 15 provides for rotating the turn-table and indexing thereof is effected by a handoperated latch 3 engaging bosses 17 in the table. The turn-table may be mounted directly on a pillar 1 or on an arm 11 rotatably secured to the pillar, which also carries a bolt 12 supported by a stay 14 and having mounted thereon a bracket 13 to steady the spindle 5 and carry the usual feeding means. An index may be provided for indicating the spindle speed in each position of the turn-table.
