KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

1 Mit dieser Sägenschärfmaschine können mehrere gleichzeitig eingespannte Sägen geschärft werden in der Weise, dafs. die Schräge der Zähne durch die Verstellbarkeit der Feilen sowie deren Antrieb verändert werden kann.1 With this saw sharpening machine several saws clamped at the same time can be sharpened are in such a way that. the bevel of the teeth due to the adjustability of the files as well as their drive can be changed.

In der Zeichnung ist eine solche Sägenschärfmaschine in der Draufsicht veranschaulicht.In the drawing, such a saw sharpening machine is illustrated in plan view.

Der gemeinschaftliche Antrieb der Schärfvorrichtungen erfolgt von einer Riemscheibe i aus, die eine in Lagern I laufende Welle w und somit die Zahnräder \ in Drehung setzt. Je eins der Räder \ steht mit gleichen Kegelrädern \l in Eingriff, wodurch die in Lagern /' umlaufenden Wellen wx bewegt werden, auf welchen je ein Stirnrad r und eine Reibungsscheibe e fest angeordnet sind. Soll die eine oder andere der Feilvorrichtungen aufser Betrieb gesetzt werden, so ist das betreffende Kegelrad ^1 durch einen der Hebel h auszurücken. Diese Antriebsvorrichtung ist auf einem Rahmen m angebracht und sind auf demselben noch Schlitzführungen u befestigt, in welchen die die Feilscheiben c tragenden Wellen w2 in Böcken b gelagert und beliebig zu verstellen und zu sichern sind. Diese Wellen jp'2 tragen je eine Reibungsrolle e\ die mit der Scheibe e in Verbindung steht, und ein Stirnrad r1, welches mit dem Stirnrad r in Eingriff zu bringen ist. Beim Feilen oder Schärfen schräger Zähne stehen, wie in der Zeichnung ersichtlich, die Reibungsräder e el mit einander in Verbindung und die Feilen schräg zum Sägeblatt s, während, wenn die Säge mit geraden Zähnen versehen werden, soll, die Stirnräder r r1 in Eingriff zu bringen sind.The joint drive of the sharpening devices is provided by a pulley i , which sets a shaft w running in bearings I and thus the gearwheels \ in rotation. One of the wheels \ is in mesh with the same bevel gears \ l , whereby the shafts w x rotating in bearings / 'are moved, on each of which a spur gear r and a friction disc e are fixedly arranged. If the one or the other of the filing devices besides operation are set, then the bevel gear ^ 1 h in question is by one of the levers to disengage. This drive device is mounted on a frame m and slotted guides u are attached to the same, in which the shafts w 2 carrying the filing discs c are supported in brackets b and can be adjusted and secured as required. These shafts jp ' 2 each carry a friction roller e \ which is connected to the disk e, and a spur gear r 1 , which is to be brought into engagement with the spur gear r. When filing or sharpening oblique teeth, as can be seen in the drawing, the friction gears ee l are connected to one another and the files are inclined to the saw blade s, while when the saw is to be provided with straight teeth, the spur gears rr 1 are in engagement are bring.

Claims (1)

Patent-Anspruch:Patent claim: Eine Sägenschärfmaschine, deren Feilscheibenachse zwecks rechtwinkligen Feilens der Sägenzähne durch Stirnräder fr rlj angetrieben wird, während zwecks schiefwinkligen Feilens der Antrieb durch Reibungsräder (e e1) erfolgt und die Lage der Feilscheibenachse durch Schlitz·^ führungen (u) gesichert wird.A saw sharpening machine, the filing wheel axis is for the purpose of rectangular quickly cutting the saw teeth driven by spur gears fr r l j, while for the purpose of oblique quickly cutting the drive by friction wheels (ee 1) takes place and the position of the filing wheel axis is secured by slot · ^ guides (u).
