Abstract
Paper drilling machine, for dispatch, capable of carrying out two to seven holes at a time, characterized by being constituted by a lower support platform, provided with holes in its longitudinal direction, and at whose ends there are supports, arranged transversely, at the ends of which articulates an upper flat surface provided with projections located on its inner face and which are parallel to the major axis, an angular piece being mounted on the lower supporting platform, one of whose sides has vertical grooves and longitudinal holes that guide to displaceable parts carrying the drilling rods, which are capable of being directed and/or fixed by means of another piece integral with it and provided with a fixing mechanism to those vertical grooves of one of the sides of the angular piece, with which it is obtained that these drill-holder parts can be fixed some to the others at convenient distances in order to obtain the holes of the paper at desired distances, achieving the holed by manual pressure on that flat top surface that pushes, by means of the projections located on its face not seen, the ends of the shanks drills, forcing them to penetrate in those holes of longitudinal direction located in the base, piercing the sheet of paper deposited on it as many times as drills are pushed, and returning the apparatus to its initial position by decompression of springs mounted around the Drill stems that had been compressed in the previous operation.
