Abstract

4028. Herbert, A., and Vernon, P. V. Feb. 18. Drilling. - In radial drilling-machines in which the feed-sleeve on the spindle is operated by a handle through rack-and-pinion gearing, additional gearing is introduced between the handle and the pinion to enable the handle to have an increased angular movement while still rotating in a plane at right-angles to the radial arm. The pinion shaft D is mounted in a casing C adjustably fixed to the saddle B, and is driven by worm or spiral gearing F, G, the gear G being mounted on a shaft at right-angles to the other shaft. The worm gearing may be replaced by spur gearing, and the extending bracket C may be adjustable in any manner.
