Description
Erfindungsgegenstand ist ein Sensen- und Messerschärfer. Er besteht aus einem gabelförmigen Handgriff, zwei Halteschalen mit Anlegekanten und zwei verschieblich auswechselbaren bogenförmigen Schärfkörpern.The subject of the invention is a scythe and knife sharpener. He persists consisting of a fork-shaped handle, two holding shells with contact edges and two movable ones exchangeable curved sharpening bodies.
Das Wesentlichste bei dem Erfindungsgegenstand sind jedoch die drei feilenartig aufgerauhten, in die Schärfkörper eingelassenen Rippen.However, the most important thing about the subject of the invention are the three Roughened file-like ribs embedded in the sharpening bodies.
Die Schärfkörper sind im Gabelkopf des Handgriffes so angeordnet, daß ihre Rippen zähneartig ineinandergreifen. Durch in Nuten der Schärfkörper eingreifende Federn werden die Schärfkörper in gleichmäßigem Abständ voneinander gehalten und können je nach Bedarf von Hand verschoben werden.The sharpening bodies are arranged in the fork head of the handle so that that their ribs mesh like teeth. By engaging in grooves of the sharpening body Feathers, the sharpening bodies are held at an even distance from one another and can be moved by hand as required.
Der sich bildende Schärfungswinkel (bei 42 mm Radius) ist so gehalten, daß genügendes Schärfen mit schlanker Schneide gewährleistet ist. Stumpf geworden, können die Schärfkörper durch Herausschieben gegen neue ausgewechselt werden.The sharpening angle that forms (at 42 mm radius) is kept in such a way that that sufficient sharpening with a slim cutting edge is guaranteed. Become dull the sharpening bodies can be exchanged for new ones by sliding them out.
Fig. i zeigt die Ansicht mit den beiden Schär=fkörpern; Fig. 2 zeigt den Schnitt durch das Oberteil der Fig. i; Fig.3 und 4 zeigen die Innenansicht mit den feilenartig aufgerauhten Rippen und die seitlichen Schalen mit den Anlegekanten.Fig. I shows the view with the two sharpening bodies; Fig. 2 shows the section through the upper part of Fig. i; 3 and 4 show the interior view with the file-like roughened ribs and the side shells with the contact edges.
Der Schärfer besteht aus dem gabelförmigen Handgriff i, den Halteschalen 2 und 2a mit den äußeren Umlegekanten 3 und 3a sowie den Einschnitten 4 und 4a, den Nuten 5 und 5a zur gleichmäßigen Bewegung der Schärfkörper 6 und 6a und den eingreifenden Federn 7 und 7a, ferner aus den Schärfkörpern mit feilenartig aufgerauhten Rippen 8 bis 8e, die zähneartig ineinandergreifen. Die Funktion ist folgende: Bei aufrecht stehender Sense setzt man den Sensenschärfer vertikal unter die Schneide, so, daß die Schneide zwischen den Einschnitten 4 und 4a liegt, dann zieht man den Sensenschärfer entlang der Schneide und wiederholt den Vorgang bis zur vollständigen Schärfung. Dabei greifen die feilenartig aufgerauhten Rippen 8 bis 8e, die bei einem Radius von 42 mm eine schlanke Schneide ergeben, die Schneide schärfend an. Diesen Vorgang wiederholt man, so oft das Schärfen erforderlich wird. Dengeln und Schärfen mit Abziehsteinen fallen dabei fort.The sharpener consists of the fork-shaped handle i, the holding shells 2 and 2a with the outer fold-over edges 3 and 3a and the incisions 4 and 4a, the grooves 5 and 5a for smooth movement of the sharpening bodies 6 and 6a and the engaging springs 7 and 7a, also from the sharpening bodies with roughened file-like Ribs 8 to 8e, which mesh like teeth. The function is as follows: At with the scythe standing upright, place the scythe sharpener vertically under the cutting edge, so that the cutting edge lies between the incisions 4 and 4a, then you pull the Scythe sharpener along the cutting edge and repeat the process until complete Sharpening. The ribs 8 to 8e, roughened like a file, grip the Radius of 42 mm result in a slim cutting edge, sharpening the cutting edge. This one Repeat the process as often as sharpening is required. Dengeling and sharpening with whetstones are no longer necessary.
Beirr Messerschärfen legt man die Schärferkante 3 oder 3a gegen die Tischplatte, hält den Handgriff vertikal nach unten und zieht mit einer Hand das zu schärfende Messer durch die Einschnitte 4 und 4a. Die Reibeflächen der Schärfkörper 6 und 6a geben nun beim Durchziehen dem Messer die schlanke Schneide.For knife sharpening, the sharpening edge 3 or 3a is placed against the Tabletop, holds the handle vertically downwards and pulls the with one hand Knives to be sharpened through incisions 4 and 4a. The rubbing surfaces of the sharpening bodies 6 and 6a now give the knife the slender edge when it is pulled through.
