Abstract

The invention relates to a novel solution to the internal system of the gang saw, in which the movement of the electric motor is transmitted to the saw blade by means of a rope. The rope is tensioned in the frame of the gang saw via rollers and fastened at both ends to the vertically movable holder of the saw blade. The rope can be fastened, at the centre of the longest direct stretch running between two rollers, eccentrically directly to the shaft of the electric motor, or by means of a crank web which transmits the motion of the electric motor to the rope only parallel to the rope. In the case where the rope is fastened directly eccentrically to the shaft of the electric motor, one roller, via which the rope leads from the electric motor to the upper holder of the saw blade, is attached to a spring in order that the stresses in the rope are damped. <IMAGE>

Description

Gattersäge betrieben mittels eines SeilesFrame saw operated by means of a rope

Die Erfindung betrifft die Vorteile einer Gattersäge, die jeder Bastler zu schätzen weiß. Leider ist eine Gattersäge in Herstellung sehr anspruchsvoll und dadurch auch teuer. Eine Vereinfachung des inneren Systems der Gattersäge ermöglicht eine billige Herstellung auch von leichteren und kleineren Gattersägen, die sich vor allem für bastler eignen.The invention relates to the advantages of a gang saw that every hobbyist appreciate. Unfortunately, a frame saw is very demanding to manufacture and therefore also expensive. A simplification of the internal system of the frame saw allows a cheap production of lighter and smaller gang saws, which especially suitable for hobbyists.

Die Vereinfachung des inneren Systems der Gattersäge besteht darin, daß die Bewegung von dem Elektromotor 1 auf das Sägeblatt mit Hilfe eines Seiles übertragen wird, das in dem Rahm der Gattersäge über Pollen eingespannt und auf beiden Enden zu den senkrecht beweglichen Halter 2 des Sägeblattes befestigt ist.The simplification of the internal system of the frame saw consists in that the movement of the electric motor 1 on the saw blade with the help of a rope is transmitted, which is clamped in the frame of the frame saw over pollen and on both ends is attached to the vertically movable holder 2 of the saw blade.

Das Seil kann in der Mitte der längsten direkten, zwischen zwei Pollen durchläufenden Strecke exzentrisch direkt zu der Achse des Elektromotors befestigt werden, oder mittels einer Kurbelwange, die die Bewegung des Elektromotors auf das Seil nur parallel mit dem Seil überträgt. In dem Fall, daß das Seil direkt exzentrisch zu der Achse befestigt wird, ist eine Rolle 3, über die das Seil von dem Elektromotor zu dem oberen Halter des Sägeblattes führt, auf einer Feder angebracht, damit die Spannungen in dem Seil gedämpft werden.The rope can be in the middle of the longest direct, between two pollen continuous route eccentrically attached directly to the axis of the electric motor , or by means of a crank arm that controls the movement of the electric motor on the Rope only transfers parallel to the rope. In the event that the rope is directly eccentric attached to the axle is a pulley 3 over which the rope from the electric motor leads to the upper holder of the saw blade, mounted on a spring so that the Tensions in the rope are dampened.
