Description
Nach dem Hauptpatent 646 224 ist vorgeschlagen worden, ein mit Sägezähnen versehenes Blatt aus Schnellstahl und ein als Rückenstützleiste dienendes Blatt aus gewöhnlichem Stahl mit ihren Enden in beiderseits angeordneten Angeln gesondert und derart zu befestigen, daß keilartig wirkende Einrich- » tungen beim Auftreten der Einspannzugkraft ein Zusammenpressen der Leisten bewirken, wobei die Anlagekanten der Leisten derart gezahnt sind, daß die Zähne der einen Leiste in die Zahnlücken der anderen Leiste eingreifen. According to the main patent 646 224 it has been proposed to provide a saw teeth Blade made of high-speed steel and a blade made of ordinary that serves as a back support strip Steel with their ends in hinges arranged on both sides separately and in such a way secure that wedge-like acting devices »when the clamping force occurs cause the strips to be pressed together, the contact edges of the strips in this way are toothed that the teeth of one bar engage in the gaps between the teeth of the other bar.
Dieser aus den beiden Leisten und den beiden Endangeln sowie den Verbindungsbolzen bestehende, zusammengesetzte Körper wird beim Sägen zwischen den Bügelsägebolzen eingespannt!This from the two bars and the two end hinges as well as the connecting bolts existing, composite body is sawing between the hacksaw bolts clamped!
Diese Bauart hat den Nachteil, daß nicht mehr normal lange Sägeblätter, sondern um das Maß der Länge der beiden Endangeln verkürzte Sägeblätter verwendet werden müssen. Um dieses Maß wird auch der Hub und somit der Arbeitsbereich der Bügelsägemaschine geringer.This type of construction has the disadvantage that no longer saw blades of normal length, but around Saw blades that are shortened to the length of the two end hinges must be used. The stroke and thus the working range of the hacksaw machine is also increased by this amount less.
Dieser Mangel soll erfindungsgemäß dadurch behoben werden, daß bei Fortfall der Endangel die Maschinenangeln mit je einem Einspannbolzen für das Zahnblatt und für das Stützblatt versehen werden.According to the invention, this deficiency is to be remedied in that, if the Endangle the machine rods with one clamping bolt each for the toothed blade and for the Support sheet are provided.
Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in Abb. ι in Längsansicht dargestellt.An embodiment of the subject matter of the invention is shown in Fig. Ι in a longitudinal view shown.
Abb. 2 stellt die Einspannanordnung des Zahnblattes gemäß Abb. ι in größerem Maßstäbe ebenfalls in Längsansicht dar.Fig. 2 shows the clamping arrangement of the toothed blade according to Fig. Ι on a larger scale also in a longitudinal view.
Der Sägebügel α ist an einer Seite mit der absatzweise mittels der Schraube b verstellbaren Angel c und an der anderen Seite mit der mittels der Spannschraube d verstellbaren Angele versehen.The saw bow α is provided on one side with the tang c, which can be adjusted in increments by means of the screw b, and on the other side with the tang, which can be adjusted by means of the clamping screw d.
Zwischen den Maschinenangeln c und e ist das mit den Sägezähnen/ versehene Zahnblatt g durch die Bolzen h eingespannt. Die darüberliegende Stützleiste/, die mit dem gezahnten Rücken gegen den gezahnten Rükken des Zahnblattes ,g" abgesteift ist, ist durch die Bolzen m, die durch Schrägschlitze der Stützleiste / gesteckt sind, zwischen den Angeln c und e eingespannt. The toothed blade g provided with the saw teeth / is clamped by the bolts h between the machine hinges c and e . The overlying support bar /, which is stiffened with the toothed back against the toothed back of the toothed blade, g ", is clamped between the hinges c and e by the bolts m, which are inserted through inclined slots in the support bar /.
*) Von dem Patentsucher ist als der Erfinder angegeben zuorden:*) The following is indicated by the patent seeker as the inventor:
Helmut Schieutermann in Renischeid.Helmut Schieutermann in Renischeid.
Beim Anziehen der Angel e durch die Schraubet wird das Stützblatt ζ infolge der Schräglage der Einspannlöcher mit seiner Rückenkante gegen die Rückenkante des Zahnblattes gedrückt. ,νΐWhen the tang e is tightened by the screw, the back edge of the support blade ζ is pressed against the back edge of the toothed blade due to the inclined position of the clamping holes. , νΐ
Das Zahnblatt5· ist statt mit schrägen o'derV parallel zur Zahnlinie verlaufenden ovalen-.;The tooth blade5 is instead of oblique o'derV oval running parallel to the tooth line .;
: Löchern, wie Abb. 2 zeigt, ijiit runden Eiii*·;■ spannlöchern versehen, die gegenüber dem Einspannbolzen h ein Spiel aufweisen, so daß bei angelegten Rückenkanten von Zahnblatt und Stützleiste, beim Anziehen der Angel um das Maßk, das Zahnblattg um das Maß/ gegen die Stützleiste / gedrückt werden kann.: Holes, as shown in Fig. 2, ijiit round Eiii * ·; ■ provided with clamping holes which have a play in relation to the clamping bolt h , so that when the back edges of the tooth blade and the support bar are placed, when the tang is tightened by the amount k, the tooth blade g by the amount / against the support bar / can be pressed.
Das Zahnblatt g kann demnach in gebräuchlichen Längen und mit üblichen runden Löchern Verwendung finden.The tooth blade g can therefore be used in customary lengths and with customary round holes.
