Hermann Nitschmann in Berlin. Handsäge, insbesondere für ärztliche Zwecke. Patentiert im Deutschen Reiche vom 20. Juni 1923 ab. Hermann Nitschmann in Berlin. Hand saws, in particular for medical purposes. Patented in the German Empire on June 20, 1923.

Gegenstand der Erfindung ist eine insbesondere für ärztliche und zahnärztliche Zwecke bestimmte Handsäge, deren Sägeblatt in einem Bügel längsbeweglich gelagert ist und durch ein im Handgriff angebrachtes Triebwerk hin und her bewegt wird.The subject of the invention is a particular for medical and dental Purposes specific hand saw, the saw blade stored in a bracket longitudinally movable and is moved back and forth by an engine mounted in the handle.

Um die Säge der Lage der Arbeitsstelle anzupassen und an schwer zugänglichen Stellen seitlich von der Einführungsöffnung liegende Schnitte ausführen zu können, ist gemaß der Erfindung der Bügel der Säge schwenkbar mit dem Stiel des HandgriffsTo adapt the saw to the location of the work site and in hard-to-reach places To be able to make cuts to the side of the insertion opening is appropriate the invention of the bow of the saw pivotable with the shaft of the handle

verbunden und in beliebiger Winkelstellung zu diesem feststellbar. Dadurch ist es ermöglicht, Schnitte auszuführen, die von der Richtung des Handgriffs abweichen.
Auf der Zeichnung ist ein Ausführungs-beispiel der Erfindung dargestellt. Abb. ι zeigt eine Säge in der Seitenansicht, Abb. 2 eine Ansicht auf die Unterseite der Säge.
Die Säge besteht aus einem hohlen Handgriff a, in dem sich ein das Sägeblatt hin und her bewegendes Triebwerk befindet. An dem Handgriff sitzt ein Stiel b, durch den das Sägeblatt m hindurchgeht und der den Bügel c trägt. Dieser ist um einen Zapfen 0 connected and lockable in any angular position to this. This makes it possible to make cuts that deviate from the direction of the handle.
An exemplary embodiment of the invention is shown in the drawing. Fig. Ι shows a saw in side view, Fig. 2 is a view of the underside of the saw.
The saw consists of a hollow handle a, in which there is a drive mechanism that moves the saw blade back and forth. On the handle sits a handle b through which the saw blade m passes and which carries the bracket c. This is around a pin 0

-15 schwenkbar am Stiel b gelagert. Der Drehzapfen wird zweckmäßig durch eine Klemmschraube/» gebildet, mittels deren der Bügel in der jeweiligen Lage feststellbar ist. Um hierbei eine sichere Führung des entsprechend der Bügelschwenkung umgebogenen Sägeblattes zu erzielen, sind am Stiel b Führungsrollen q und am Bügel c Führungsrollen r vorgesehen, zwischen denen das Sägeblatt liegt. Die Führungsrollen r werden zusam- f men mit dem Bügel c geschwenkt, so daß das Sägeblatt m innerhalb der Rollenführung eine der Winkelstellung des Bügels sich anpassende Schrägführung erhält. Das freie Ende des Sägeblattes wird in einem entsprechend geschlitzten Teil c des Bügels geführt.-15 pivoted on handle b . The pivot is expediently formed by a clamping screw, by means of which the bracket can be locked in the respective position. In order to achieve reliable guidance of the saw blade, which is bent over in accordance with the pivoting of the bracket, guide rollers q are provided on the handle b and guide rollers r on the bracket c, between which the saw blade lies. The guide rollers r are swiveled together with the bracket c , so that the saw blade m is provided with an inclined guide within the roller guide which adapts to the angular position of the bracket. The free end of the saw blade is guided in a correspondingly slotted part c of the bracket.
