Apparat zum Schärfen von Sensen.Apparatus for sharpening scythes.

Der Apparat besteht aus zwei Doppelhebeln H1 H^ bezw. hj h2, welche um Stifte S1 s.2 drehbar mit denselben an dem Kloben K befestigt sind. An den Enden der oberen Hebelarme \ h2 sind um Stifte lose drehbare Röllchen rx r2 angeordnet. Am vorderen Theile des Klobens K ist vermittelst Schrauben die Platte ρ befestigt, in deren schrägen Schlitzen die aus bestem Stahl hergestellten Messer JW1m2 Aufnanme finden. Die schräg eingeführten Messer mx m2 bilden an ihren zusammenstofsenden Flächen einen nach oben und aufsen erweiterten Schlitz und sind derartig geschärft, dafs dieselben bei der Ingebrauchnahme des Apparates die Sensenschneide hobelartig bearbeiten bezw. schärfen. Am hinteren Theile des Klobens K ist ferner, auf einem Stifte lose drehbar, das mit einer Nuth versehene verstellbare Führungsröllchen f angeordnet. Die beiden seitwärts aufstehenden Lappen Z1 I2 des Klobens K dienen zum Anlegen der Hebel H1 H2. The apparatus consists of two double levers H 1 H ^ respectively. hj h 2, which to pins S 1 s. rotatably mounted with the same on the clamp K 2. At the ends of the upper lever arms \ h 2 loosely rotatable rollers r x r 2 are arranged around pins. On the front part of the block K , the plate ρ is fastened by means of screws, in the oblique slots of which the knives JW 1 m 2, made of the best steel, are accommodated. The obliquely introduced knives m × m 2 form on their cohesive surfaces a slot widened upwards and outwards and are sharpened in such a way that they machine the scythe-like blade like a plane when the apparatus is used. sharpen. On the rear part of the block K there is also arranged, loosely rotatable on a pin, the adjustable guide roller f provided with a groove. The two side tabs Z 1 I 2 of the block K are used to apply the levers H 1 H 2 .

Behufs Schärfens der Sense setzt man den Apparat derartig an dieselbe, dafs deren Schnittfläche in den durch die Messerenden mx m2 gebildeten Schlitz zwischen den Röllchen T1 r2 gleitend in die Nuth der Führungsrolle f zu liegen kommt. Hierauf zieht man den Apparat vermittelst der Hebelarme H1 H2 über die Sense hin und zurück, so dafs durch die scharfen, hobelartigen Kanten der Messer ein Span von der Sense abgeschabt wird. Ein Hauptvorzug des Apparates soll der sein, dafs man durch ihn eine gleichmäfsige scharfe Schnittfläche erzielen soll.In order to sharpen the scythe, the apparatus is placed on it in such a way that its cut surface comes to rest in the slot formed by the knife ends m x m 2 between the rollers T 1 r 2 and slide into the groove of the guide roller f . The apparatus is then pulled back and forth over the scythe by means of the lever arms H 1 H 2 , so that a chip is scraped off the scythe by the sharp, plane-like edges of the knife. One of the main advantages of the apparatus is said to be that it is intended to achieve a uniform, sharp cut surface.
