HANS FRIEDRICH in LEIPZIG. Wippsäge für Handbetrieb.HANS FRIEDRICH in LEIPZIG. Tilting saw for manual operation.
Patentirt im Deutschen Reiche vom 31. Januar 1879 ab.Patented in the German Empire on January 31, 1879.
Bei der auf beiliegender Zeichnung gezeichneten einfachen Handlaubsäge ist sowohl eine genauere Geradführung des Blattes erzielt, als auch durch die Anordnung des Hebels p ein bequemes und leichtes Handhaben ermöglicht. Ferner wird durch die Vorrichtung q ein stetes Festhalten des zu bearbeitenden Stückes bewirkt und dadurch eine grofse Erleichterung geschaffen. Da der Hebel eine schwingende Bewegung macht, und infolge dessen das Geradführen der Säge beeinträchtigt würde, so ist die Anordnung insofern eigenthümlich gewählt, als der Hebel/ mit dem Sägeblatthalter 0 in keiner Weise fest verbunden ist, sondern seinen Schwingungen frei folgen kann, indem er während der Bewegung über den Stift i gleitet.In the simple hand-held jig saw shown in the accompanying drawing, both a more precise straight-line guidance of the blade is achieved and the arrangement of the lever p enables convenient and easy handling. Furthermore, the device q ensures that the piece to be worked is held firmly in place, thereby making it much easier. Since the lever makes an oscillating movement, and as a result the straightening of the saw would be impaired, the arrangement is peculiarly chosen in that the lever / is in no way firmly connected to the saw blade holder 0 , but can freely follow its oscillations by being slides over the pen i while moving.
Die Vorrichtung q besteht aus einer Feder r oder ähnlichem Mittel, welche an den oberen Arm P entsprechend befestigt ist und eine Verstellung je nach der Stärke des Brettes gestattet. Um die vorgezeichneten Linien nicht zu verdecken, ist r unten entsprechend gabelförmig gestaltet und kann auch aus durchsichtigem Material bestehen. Im übrigen wird die Spannung des Sägeblattes durch eine Spiralfeder s erzielt, welche mittelst der Mutter t mehr oder weniger angespannt werden kann.The device q consists of a spring r or similar means which is appropriately attached to the upper arm P and allows adjustment according to the thickness of the board. In order not to obscure the pre-drawn lines, the bottom r is appropriately fork-shaped and can also consist of transparent material. In addition, the tension of the saw blade is achieved by a spiral spring s, which can be tightened to a greater or lesser extent by means of the nut t.
