Description
(Sch(NS
Die Erfindung betrifft eine Bügelsäge mitThe invention relates to a hacksaw with
freiem Rückgang und besteht darin, daß der Sägebügel durch einen Lenker mit einem Hebel verbunden ist, der bei Beginn des Rücklaufs des Sägebügels mittels eines Reibgessperres festgestellt wird, so daß der Lenker um einen festen Punkt schwingt und dadurch das Abheben des Sägebügels bewirkt.free decline and consists in the fact that the saw bow by a handlebar with a Lever is connected, which is determined at the beginning of the return of the saw bracket by means of a Reibgessperres, so that the The handlebar swings around a fixed point, causing the saw frame to lift off.
Auf der Zeichnung ist die Erfindung inIn the drawing, the invention is in
ίο einer Ausführungsform beispielsweise dargestellt, und zwar zeigt die Abbildung eine Seitenansicht der Bügelsäge in zwei verschiedenen Arbeitsstellungen.ίο one embodiment shown, for example, namely the figure shows a side view of the hacksaw in two different ways Working positions.
Der Bügel ι ist durch einen Lenker 2 mit einem um den Zapfen 3 des Maschinengestell 4 schwingbaren Hebel 5 verbunden. Dieser Hebel 5 ist auf dem dem Zapfen 3 gegenüberliegenden Ende als bogenförmige Bahn 6 ausgebildet, die mit einem um denThe bracket ι is by a link 2 with a pin 3 of the machine frame 4 swingable levers 5 connected. This lever 5 is on the pin 3 opposite end formed as an arcuate path 6, which with a to the
ao Zapfen 7 drehbaren Feststellhebel 8 zusammen arbeitet. Der Hebel 8 dient zum Feststellen des Hebels 5 beim Rückgang des Sägebügels vermittels der bogenförmigen Bahn 6 und ist zu diesem Zwecke mit einer Ledereinlage 9 versehen, die der bogenförmigen Bahn 6 entsprechend geformt ist. Der Feststellhebel 8 ist durch eine Feder 10 belastet, deren Druck mittels der am Maschinengestell 4 angebrachten Stellvorrichtung 11 geregelt werden kann. Um den Feststellhebel 8 abwechselnd in seine feststellende und freigebende Lage zu bringen und ihn in letzterer zu halten, sind zwei Steuerstangen 16 und 17 sowie eine Sperrklinke 20 vorgesehen. Der Antrieb der Steuerstangen 16 und 17 erfolgt durch den Schwinghebel 12, welcher um den Zapfen 13 im Lagerbock 14 schwingt und von der Kurbel 15 angetrieben wird. Zu diesem Zwecke sind die beiden Steueristangen 16 und 17 ober- und unterhalb des Zapfens 13 durch die Zapfen 18 und 19 mit dem Schwinghebel verbunden. Die Steuerstangenao pin 7 rotatable locking lever 8 works together. The lever 8 is used to lock of the lever 5 when the saw bow falls by means of the arcuate path 6 and is for this purpose with a Leather insert 9 is provided, which is shaped to correspond to the arcuate web 6. Of the The locking lever 8 is loaded by a spring 10, the pressure of which by means of that on the machine frame 4 attached adjusting device 11 can be regulated. To the locking lever 8 alternately to bring him into his determining and releasing position and him in the latter To hold, two control rods 16 and 17 and a pawl 20 are provided. The control rods 16 and 17 are driven by the rocker arm 12, which swings around the pin 13 in the bearing block 14 and is driven by the crank 15. to For this purpose, the two control rods 16 and 17 are above and below the pin 13 connected by the pins 18 and 19 to the rocker arm. The control rods
16 und 17 werden durch zwei Führungslaschen 22 und 23 gehalten, welche pendelnd an dem, Maschinengestell 4 »aufgehängt sind. Das Arbeiten der Säge geht wie folgt vor sich:16 and 17 are held by two guide tabs 22 and 23, which pendulum on which, machine frame 4 "are suspended. The saw works as follows themselves:
Die in der Zeichnung gewählte Stellung der Säge zeigt den Sägebügel in seiner äußersten Linkslage, also bei Beginn des Rückganges. Die Steuerstange 16 hat durch Anstoßen an die Sperrklinke 20 dieselbe ausgeklinkt und so den Feststellhebel 8 freigegeben, der durch die Feder 10 gegen die bogenförmige Bahn 6 des Hebels 5 gedrückt wird und letzteren feststellt. Der Bolzen 24 ist dadurch ortsfest geworden, und der Lenker 2, welcher um diesen Bolzen 24 schwingt, kann jetzt nur nach oben ausweichen. Dadurch wird beim Rückgang der Sägebügel 1 in die in der Abbildung gestrichelte Lage gebracht und somit das Sägeblatt vom Werkstück abgehoben.The position of the saw selected in the drawing shows the saw bow in its extreme left position, i.e. at the beginning of the decline. The control rod 16 has through Butt against the pawl 20 the same notched and so released the locking lever 8, which is pressed by the spring 10 against the arcuate path 6 of the lever 5 and the latter notices. The bolt 24 has become stationary, and the Link 2, which swings around this bolt 24, can now only move upwards. As a result, when the saw bow 1 falls into the dashed line in the figure Positioned and thus lifted the saw blade from the workpiece.
»Hat nun bei Beginn des Arbeitshubes der Sägebügel 1 seine äußerste Rechtslage erreicht, so hat die Steuerstange 17 durch Anas stoßen an den Stift 21 den Feststellhebel 8 von der bogenförmigen Bahn 6 abgehoben, die Sperrklinke 20 ist eingefallen und hält den Feststellhebel 8 fest. Der Bolzen 24 ist jetzt nicht mehr ortsfest, sondern um den Zapfen 3 schwenkbar. Der Lenker 2 kann somit nach unten ausweichen, und das Sägeblatt setzt sich auf das Werkstück auf.»If the saw frame 1 has now reached its extreme right position at the start of the working stroke, so the control rod 17 has the locking lever 8 abut the pin 21 by anas lifted off the arcuate track 6, the pawl 20 has collapsed and holds the locking lever 8 firmly. The bolt 24 is now no longer stationary, but around the Pin 3 pivotable. The handlebar 2 can thus give way down, and the saw blade sits down on the workpiece.
