KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft Nägel und Krampen mit gespaltenem Schaft und ist dadurch gekennzeichnet, dafs an dem Punkte d, wo der feste Theil b und der gespaltene Theil c des Schaftes an einander stofsen, dem Schafte eine schraubenartige Drehung gegeben ist, wodurch bezweckt wird, dafs die beim Eintreiben in die zu nagelnde Fläche infolge des sich in den Spalt eindrängenden Holzkeiles bedingte krallenförmige Ausspreizung der gespaltenen Schaftspitzen sich nur bis zu dem Punkte d vollziehen kann. Diese Drehung soll bei etwaigen Mängeln des verwendeten Materials oder bei Schweifsfehlern bei aus mehreren einzelnen Stücken zusammengeschweifsten Nägeln und Krampen ein Reifsen über den Punkt d hinaus verhindern.The invention relates to nails and staples with a split shank and is characterized in that at the point d where the fixed part b and the split part c of the shank abut, the shank is given a helical rotation, the aim of which is that the when driving into the surface to be nailed, the claw-shaped expansion of the split shaft tips caused by the wooden wedge penetrating into the gap can only take place up to point d . This rotation is intended to prevent any defects in the material used or in the event of tail defects in nails and staples that are twisted together from several individual pieces from hoaring beyond point d.
