Abstract

721,156. Drilling. HAUSHERR, R., HAUSHERR, G., and HAUSHERR, H., [trading as HAUSHERR UND ERBEN KOMMANDIT.-GES., R.]. Sept. 11, 1951 (Sept. 11, 1950], No. 21406/51. Class 83 (3). A drilling machine comprises a driving motor 1, a number of shaft parts 11 each of which is formed with a toothed portion 13, independent gearing 25 for engaging a toothed part 13, and means 15 for locking a part 11 against rotation. The motor 1 is of non-reversible sliding-vane type. In operation, when a feed motor 7 rotating a screw 4 has advanced a part 11 to its full extent, the motors 1 and 7 are stopped, the locking device 15 is engaged, by a hand lever, with a hexagonal portion 12 on the part 11 and the gear 25 swung by a second lever into engagement with a pinion 13. The pinion 25 is then manually rotated by a gear 22 to unlock the parts. Water is supplied through bores in the shaft parts 11 via an inlet 9. Fixed or movable supports 32 for the shaft may be provided.
