  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-

 kuppeln und den unteren, den Bohrer tragenden Bolzen mitnehmen. Die unmittelbare Beeinflussung des Schlagbolzens ist an sich bei nicht zentrischer Anordnung der beiden Hubteile bekannt.

   Die hier benutate zentrische Anordnung mit zahlreichen Zähnen an den

 Zeit, dies ist ein wesentlicher   Funkt, der Erfindung.   



   In der Zeichnung ist ein Ausfuhrungsbeispiel eines solchen Bohrers im Schnitt dargestellt. 



   In einem Rohr a sitzt en Bolzen f, der an seinem oberen Ende e eine beliebige Anzahl Zähne in beliebiger   Höhe L'sit/t. Auf   diesem Bolzen sitzt ein zweiter Bolzen b, der an seinem Ende d dieselben Zahne wie der Bolzen   l besitzt,   Dieser Bolzen b steht unter Einwirkung einer Feder   (,   die aber nicht den Zweck hat, den   Bo) zen vorzutreiben,

  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

 couple and take the lower bolt carrying the drill with you. The direct influence of the firing pin is known per se when the two lifting parts are not arranged centrally.

   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,

beide Bolzen Zähne in gleicher Anzahl und gleicher Höhe tragen, dadurch gekennzeichnet. dass der den Hammer oder Merfile tragende Bolzen (b) durch das Aufeinandersteigen der Zahne unmittelbar vorgetriehen und von einer Rückschlagfeder (c) zu neuem Eingriffe seiner Zähne in die Zahnlücken deh anderen Bolzens (e, f) zurückbewegt wird, während bei einer Umkehrung der Drehrichtung der Antriebswelle ein Kuppeln der Zähne in der Weise stattfindet. dass der das Werkzeug tragende Bolzen (b) Drehbewegung empfängt und somit als Bohrvorrichtung benutzbar wird. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. both bolts carry teeth in the same number and the same height, characterized. that the bolt (b) carrying the hammer or merfile is immediately advanced by the rising of the teeth and is moved back by a return spring (c) to re-engage its teeth in the gaps between the teeth of the other bolt (e, f), while in the event of a reversal of the direction of rotation of the drive shaft coupling of the teeth takes place in this way. that the bolt (b) carrying the tool receives rotary movement and can thus be used as a drilling device. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
