KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei vorliegender Bügelsäge wird ein einfaches und gefahrloses Nachspannen des Blattes dadurch erreicht, dafs dasselbe mit Schlitzen versehen ist, welche stellenweise in Rasten (Einkerbungen) auslaufen.With the present hacksaw a simple and safe re-tensioning of the sheet is achieved by providing it with slits is, which in places run out in notches (notches).
In der Zeichnung ist eine solche Säge veranschaulicht, und zwar zeigt:Such a saw is illustrated in the drawing, which shows:
Fig. ι die ganze Säge, während dieFig. Ι the whole saw, while the
Fig. 2 und 3 Einzelheiten in Ansicht und Druntersicht in gröfserem Mafsstabe darstellen.FIGS. 2 and 3 show details on a larger scale in elevation and bottom view.
Fig. 4 ist eine Abänderung.Fig. 4 is a modification.
Das Blatt α ist, wie aus Fig. 2 zu ersehen ist, an einem, erforderlichenfalls auch am änderen Ende mit einem Schlitze b und Rasten c versehen. In eine dieser Rasten wird ein am Bügel d oder an einem Zwischenstück e befestigter Stift f oder eine Schraube oder ein Niet geschoben, wodurch das Blatt a gespannt und festgehalten wird. Vermöge des Schlitzes, durch welchen alle Rasten unter einander verbunden sind, wird im Gegensatze zu bekannten Ausführungen, bei welchen das Sägeblatt Löcher aufweist, der wesentliche Vortheil erreicht, dafs man den Stift f nicht herauszunehmen braucht.As can be seen from FIG. 2, the sheet α is provided with a slot b and notches c at one end, if necessary also at the other end. A pin f or a screw or rivet attached to the bracket d or to an intermediate piece e is pushed into one of these notches , whereby the sheet a is tensioned and held in place. By virtue of the slot through which all notches are connected, in contrast to known designs in which the saw blade has holes, the essential advantage is achieved that the pin f does not have to be removed.
Bei oben erwähnten Sägen mufste dies geschehen, welche Arbeit einerseits sehr umständlich, andererseits mit Gefahren verbunden war, wenn z. B. durch plötzliches Herausziehen eines streng passenden Stiftes der Bügel sich jäh entspannte. Des Weiteren kann bei Anwendung eines hülsenartigen Zwischenstückes e der Stift/ ein- für allemal eingenietet werden, wodurch die Vorrichtung an Festigkeit gewinnt. In the case of saws mentioned above, this had to be done, which work was on the one hand very cumbersome and on the other hand associated with dangers, if z. B. by suddenly pulling out a strictly matching pin, the bracket suddenly relaxed. Furthermore, when using a sleeve-like intermediate piece e, the pin can be riveted once and for all, whereby the device gains strength.
Am anderen Ende wird das Sägeblatt zweckmäfsig durch einen Bolzen g am Bügel festgehalten, welcher sowohl durch das Sägeblatt als auch durch den Bügel reicht.At the other end, the saw blade is expediently held on the bracket by a bolt g which extends both through the saw blade and through the bracket.
Fig. 4 zeigt ein Stück eines Sägeblattes, bei welchem die Rasten c zum Zwecke einer sicheren Verbindung mit dem Stifte tiefer gehalten sind, wodurch ein Steg h entsteht.Fig. 4 shows a piece of a saw blade, in which the notches c are held lower for the purpose of a secure connection with the pin, whereby a web h is formed.
