Der Hohlcylinder C, welcher den Bolzen umgiebt, ist mit Schlitzen α versehen, so dafs zwei oder mehr Stäbe b vorhanden sind, welche unten geschärfte Spitzen erhalten.The hollow cylinder C, which surrounds the bolt, is provided with slits α , so that two or more rods b are present, which have tips sharpened at the bottom. Der Bolzen wird in das gebohrte Loch gesteckt und dann der Hohlcylinder C über den Bolzen gleichfalls in das Bohrloch geschoben und mit einem Hohleisen eingetrieben, worauf die Stäbe b des Cylinders C wegen des kegelförmigen Ansatzes B in schiefer Richtung in das Holz eindringen (Fig. 3).The bolt is inserted into the drilled hole and then the hollow cylinder C is also pushed over the bolt into the borehole and driven in with a gouge, whereupon the rods b of the cylinder C penetrate the wood in an oblique direction because of the conical extension B (Fig. 3 ). Bei dieser Construction ist das Ausziehen oder Lockerwerden des Bolzens ganz unmöglich, weil der kegelförmige Ansatz B sich bei jedem Anziehen des Nagels .4. fester an die Stäbe b preist.With this construction, it is impossible to remove or loosen the bolt because the conical extension B moves each time the nail is tightened .4. praises more firmly to the bars b. Pat ε ν τ-An sp ruch:Pat ε ν τ claim: Um das Lockerwerden von Schraubenbolzen in Holzschwellen zu verhindern oder das Ausziehen derselben zu erschweren bezw. unmöglich zu machen: eine Hülse C, deren Zacken b über die kegelförmig gestalteten Bolzenenden strahlenförmig und in schiefer Richtung in das Holz geführt werden.In order to prevent the loosening of bolts in wooden sleepers or to make it difficult to pull them out. impossible to make: a sleeve C, the prongs b of which are guided radially and obliquely into the wood over the conical bolt ends.
