Abstract

178,569. Pearn, W. A. Jan. 20, 1921. Drilling-machines.-A vertical drilling-machine comprises a column c provided with horizontal guides b at the upper end, on which the drilling head is adapted to slide. A rotatable table d is carried on a knee bracket e which is provided with T-slots and is mounted to permit of vertical and transverse adjustment on the column c. A change and reverse gear is mounted in the base of the vertical column and drives bv belt and change gear 5 the horizontal shaft 4 which is geared to the drill-sprindle a. Hand and power feed are provided, the latter being belt driven from the shaft 4 through change gearing 9. A spring counterbalance is provided for the spindle.
