Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Den Gegenstand der vorliegenden Erfindung bildet eine fahrbare Baumsäge mit Motorantrieb, bestehend aus zwei Kreissägen, die einander entgegengesetzt umlaufen und beständig gegen den Bäum vorgeschoben werden. The subject of the present invention is a mobile tree saw with a motor drive, consisting of two circular saws, which rotate in opposite directions and are resistant be pushed forward against the tree.

Die Kreissägen stehen mit ihren Schneidkanten einander in gleicher Höhe gegenüber, sind jedoch so weit voneinander entfernt, daß ίο der Stamm nicht ganz durchgesägt wird, um vor dem Umstürzen des Stammes die Sägemaschine in Sicherheit zu bringen. Das Umreißen des Stammes wie üblich durch Seile bietet alsdann keine Schwierigkeiten mehr.
Fig. ι der Zeichnung zeigt die Maschine in einem Grundriß in teilweisem Schnitt und
The circular saws face each other with their cutting edges at the same height, but are so far apart that ίο the trunk is not completely sawed through in order to bring the sawing machine to safety before the trunk falls over. Outlining the trunk as usual with ropes then no longer presents any difficulties.
Fig. Ι of the drawing shows the machine in a plan in partial section and

Fig. 2 dieselbe in einem Längsschnitt.Fig. 2 the same in a longitudinal section.

Die Sägemaschine besteht aus dem eigentlichen Gestell a, auf welchem ein zweites Gestell b verschiebbar geführt ist, auf welchem die Kreissägen c, d gelagert sind.The sawing machine consists of the actual frame a, on which a second frame b is slidably guided, on which the circular saws c, d are mounted.

Der Antrieb der Kreissägen c, d erfolgt durch zwei Kegelradvorgelege e, f. Das eine Kegelrad e1 des Vorgeleges e ist in einer Keil-,25 nut g1 der Welle g gelagert, welche letztere an dem verschiebbaren Gestell b befestigt ist und am Ende das Vorgelege/ aufnimmt.The circular saws c, d are driven by two bevel gears e, f. One bevel gear e 1 of the back gear e is mounted in a wedge, 25 groove g 1 of the shaft g , which the latter is attached to the displaceable frame b and at the end the additional gear / takes up.

Das Vorgelege β ist an dem WagengestellThe intermediate gear β is on the carriage frame

gelagert. An der Vorgelegewelle k des Vorgeleges / sind Zahnräder i, k vorgesehen, die ihre Drehung vermittels Gelenkketten I, m, welche über Rollen oder Scheiben v, w geleitet werden, und Zahnräder n, 0 auf die Kreissägen übertragen.stored. On the countershaft k of the countershaft / are gears i, k which transmit their rotation to the circular saws by means of link chains I, m, which are guided over rollers or disks v, w , and gears n, 0.

Die Verschiebung des Schlittens beim Sägen wird durch eine Spindel p bewirkt, deren Mutterschloß q am Wagenschloß gelagert ist, und durch eine Schaltklinke r, die vermittels einer Kurvenscheibe s der Hauptantriebswelle t durch einen Doppelhebel u gedreht wird, wodurch die Spindel mit dem Schlitten vorgeschoben wird.The sliding of the carriage during sawing is effected by a spindle p , the nut lock q of which is mounted on the carriage lock, and by a ratchet r, which is rotated by means of a cam disc s of the main drive shaft t by a double lever u , whereby the spindle is advanced with the carriage .
