All Bohrvorrichtung benutzbarer Federhammer.
Gegenstand der Erfindung gehört zu den Federhämmern, bei denen ein in einer Hülse sitzender gezahnter Schlagbolzen mit Hilfe eines anderen in derselben Hülse liegenden gezahnten Bolzens vorgetrieben wird. Von der üblichen Art dieser Hammer unterscheidet sich die Erfindung dadurch, dass das Vortreiben des Bolzens nicht durch Fcderwirkung, sondern unmittelbar durch die Verzahnung des in Drehung versetzten gezahnten Gegenbolzens bewirkt wird, während die Feder beim Vortreiben gespannt wird und zum Rücli- führen des Schlagbolzens dient. Ausserdem kann der Hammer bei Umkehrung der Dreh-

All drilling jig usable spring hammer.
The subject of the invention belongs to the spring hammers in which a toothed firing pin seated in a sleeve is driven with the aid of another toothed bolt located in the same sleeve. The invention differs from the usual type of hammer in that the advancement of the bolt is not effected by the action of a spring, but directly by the toothing of the toothed counter bolt that is set in rotation, while the spring is tensioned during advancement and serves to return the firing pin . In addition, the hammer can be reversed

In the drawing, an exemplary embodiment of such a drill is shown in section.
In a tube a sits a bolt f, which at its upper end e has any number of teeth at any height L'sit / t. On this bolt sits a second bolt b, which at its end d has the same teeth as bolt l.This bolt b is under the action of a spring (which, however, does not have the purpose of driving the bolt forward,
