Abstract

28,944. Ott, H. A. Dec. 10. Hand a n d b r e a s t d r i l l s . - A portable hand-drill, of the type in which the drill spindle is driven at a high speed by means of gearing, has the gear-wheels mounted between parallel walls of a casing i, which encloses, by means of a bell-mouthed extension, a fly-wheel g mounted at the end of the drill spindle. To check vibration, the spindle a is mounted in a casing, and the gyroscopic effect of the flywheel assists in maintaining the spindle in any operating position. The fly-wheel may be formed in one with the lower bevel gear-wheel f.
