Gegenstand der Erfindung ist ein besonders von Schuhmachern verwendetes Gerät zur Herstellung von- Nagel- und Stiftlöchern und kennzeichnet sich dadurch, daß es mit einem durch Handdruck zu betätigenden, kniehebelartigen Ausheber versehen ist.The invention relates to a device used particularly by shoemakers for Manufacture of nail and pin holes and is characterized by the fact that it is with a is provided to be operated by hand pressure, toggle-like lifter.
Die Zeichnung veranschaulicht den Gegenstand der Erfindung in Ansicht. Das Gerät besteht in bekannter Weise aus dem von derThe drawing illustrates the subject matter of the invention in perspective. The device consists in a known way from that of the
ίο Hand zu haltenden Schaft α mit Futter b, in dem die Ahle c auswechselbar befestigt ist. Die Neuerung wird nun darin gesehen, daß die Ahle c ein Ausheber e1 lose umfaßt, der durch ein an das Schaftende f angelenktes Kniehebel werk auf das Werkstück bewegt wird, wobei die Ahle c entsprechend der Verringerung des Knickwinkels ausgehoben wird. Das Kniehebelwerk besteht aus einem bei f drehbar befestigten, löffelartigen, von den Fingern zu umfassenden Druckhebel d, von dessen Gelenkpunkt i die Zwischenstange e zum Ausheber e1 führt. Damit die Hebel nach einem Aushub selbsttätig in die Knickstellung zurückkehren, ist zwischen Schaft a und Druckhebel d eine Feder h eingeschaltet, die in einer Schaftbohrung liegt und um einen drehbaren Führungssplint g gewunden ist. Eine Knickstellung in der Nähe der Endlage ist in Strichpunktmanier eingezeichnet.ίο Hand-held shaft α with chuck b, in which the awl c is fastened in an exchangeable manner. The innovation is now seen in the fact that the awl c loosely includes a lifter e 1 , which is moved by a toggle mechanism articulated to the shaft end f on the workpiece, the awl c being lifted according to the reduction in the kink angle. The knee lever mechanism consists of a fixed at f rotatable spoon-shaped, i.e., from the fingers to comprehensive pressure lever, runs from the hinge point i e for the intermediate rod lifter e. 1 So that the levers automatically return to the bent position after excavation, a spring h is switched on between the shaft a and pressure lever d , which lies in a shaft bore and is wound around a rotatable guide pin g. A kinked position near the end position is shown in a dot-dash style.
