Abstract
"MANUAL DEVICE FOR DRILLING DOCUMENTS", characterized by the fact that inside two boxes, which protrude from the support base of the driller, two groups of three punches have been arranged to drill the holes in the paper when being pressed by the crosspiece of the actuating lever, which is articulated on a horizontal axis, having provided, on the back of said crosspiece, a guide through which slide two sliding strips, in which a series of holes arranged at different distances between Yes, they are arranged so that they coincide, or not, with the holes made in the crosspiece, in correspondence with the two groups of boring punches, in order to be able to determine the number and distance of the holes to be practiced in the document.
