Abstract
Improvements introduced in the construction of drills -freshes characterized by a new organization of the transmission of the effort of an engine through a change of speeds formed by a driving pulley secured to a driving shaft continuation of the motor shaft provided externally of grooves for trapezoidal belt; another idle rotating conical intermediate pulley in an immobile shaft parallel to the driving shaft provided with grooves located in the same planes as the grooves of the driving pulley, provided with another groove in a lower plane and provided with a toothed pinion at its lower end; another driven pulley located under the driving pulley wedged in a spindle-bearing shaft aligned with the driving shaft provided with a throat which results in the same plane as the throat of the lower plane of the intermediate pulley and provided with a toothed crown at its end lower but in a different plane than the toothed pinion mentioned; a group of pinion and crowns and superimposed on a vertical axis rotating in a core that can be placed so that they are meshed said pinion and crown respectively with the aforementioned crown of the driven pulley and with the cited sprocket of the intermediate pulley, and an eccentric device for supporting the axis of the intermediate pulley controlled by an external handle so that said axis can approach or move away parallel to the driving shaft.
