Abstract
Improvements in the change of speeds of the "berbiqui" type hand drills, achieved by the single side sliding of the crank shaft, characterized by having two cylindrical toothed wheels inserted into the single crank shaft, a first integral with it and a second crazy on the same axis; the first is provided laterally with pins that can fit into side holes of the second; the first wheel is engageable with a cylindrical other joined to a second axis parallel to said axis of the crank and the diameter of said crank is somewhat greater than that of the first wheel with it; said second idler on the crank shaft is continuously engaged in another cylindrical wheel integral with said second axis and the diameter of this latter wheel is much smaller than that of said second idler wheel; Said second shaft carries a conical wheel integral to transmit by means of a conical pinion, the movement of the crank to the axis of the tool, which is perpendicular, as is ordinarily, to said first and second axes.
