Abstract
A machine for sharpening the front end of a substantially cylindrical metallic screw, comprising a pair of complementary stamps, means mounting said stamps for selective relative movements with respect to each other and between a fixed open position and a fixed closed position. pair of pairs of active faces supported respectively by said stamps and arranged in close proximity to each other with a predetermined free space between them when said stamps occupy said fixed closed position, a pair of even recesses formed respectively on said active faces and arranged in mutual coincidence, each of said recesses having a substantially semiconic configuration, the front end of a raw screw can easily be inserted into a working position disposed between said active faces and in cooperative relation with said recesses when said stamps occupy said fixed open position, having a As a consequence of the movement of said stamps to said fixed closed position, first, the clamping between them of the leading end of a raw screw in its position to work it and then stamping a substantially conical tip on the forward end of the screw, in the rough and, finally, breaking the front end burr of the raw screw, and a pair of even supports supported respectively by said stamps and applying directly to each other in said fixed closed position to establish said predetermined free space between said active faces in said closed position fixed, said predetermined free space being said, between said active faces, in said fixed closed position, sufficiently small to ensure rupture of the burr of the forward end of the raw screw and being sufficiently large to prevent these active faces from colliding with each other.
