Abstract
An improvement in drilling machines, characterized in that it comprises a spindle that is arranged horizontally at the base of the drills, said spindle carrying the square that receives the actuating handle at its front end; a nut guided, as well as displaceable along the spindle itself in one or the other direction, according to the rotation thereof; and a lower tow that is attached at one end to the displaceable screw of the spindle and passes into the column of the machines through a side hole to rise sliding on a pulley of the foot of the column itself to link by means of a the end of the pulley with a top tow, which, in turn, is fixed at one end to the closing part of the upper extremity of the column, while it is fastened at the opposite end in an "ad hoc" part of the upper part of the head, after passing over a pulley mounted above said upper closing part.
