Abstract

24,478. Charles, E., and Grandjean, J. Oct. 28. Hand and breast drills.-A change speed gear for a drill comprises a crank disk 1 mounted on a spindle journaled in the drill frame 11 and provided with concentric rings of holes 8 adapted to engage a pinion 3 on the drill spindle 7. A slot 9 between the rings of holes allows for the transfer of the pinion from one ring to another.
