Abstract

13,316. Barbier, S. June 7. Drilling-machines.-Portable machines in which the driving-shaft is at right angles to the spindle have the cutting-torque partly or wholly overcome by gyroscopic action due to centrifugal masses, the centre of gravity of which is in or near the spindle axis, arranged on the driving-shaft. As shown in Fig. 1, the armature of the motor which drives the tool is made heavy, and the tool is driven through gearing 2, 3 and bevel-gearing 5, 6, the thrust of the tool being taken up by ball bearings against the frame 8.
