Abstract
Perfected multiple drill, which comprising a head provided with an electric motor and an alignment of vertical chuck shafts, is essentially characterized in that the transmission between motor and chuck is determined by a single belt or endless belt, arranged between pulleys of the motor shaft and chuck shafts, collaborating with the latter intermediate pulleys or rollers arranged staggered with respect to the pulleys of the chuck shafts, zigzagging said transmission belt around said pulleys of the chuck and intermediate trees, alternatively, achieving a transmission to the chuck shafts in the same direction of rotation; while said intermediate pulleys are normally supported by a horizontal plate, displaceable laterally by means of the relationship of the ends of said plate with screws that regulate the separation between said intermediate pulleys and those of said chuck shafts, achieving a tension regulation of the belt of transmission; the situation of said support plate of the intermediate pulleys being fixed, by means of captive screws passing through slots of said head; collaborating, advantageously, with said pulley of the motor shaft, two rollers or pulleys, collateral and external to the transmission belt, whose pulleys narrow the belt fence, around said pulley of the motor shaft, increasing the contact surface between this pulley and strap.
