Description

Messerschärfer. Gegenstand der Erfindung ist ein Messerschärfer nach Patent 336391, der gegenüber dem Hauptpatent so abgeändert ist, daß seine Widerstandsfähigkeit gegen Formänderung beim Gebrauch bei Vereinfachung der Herstellung wesentlich erhöht ist. Die Abänderung besteht darin, daß die die Drahtspiralen tragenden Stützen aus einem gemeinsamen Stück hergestellt sind.Knife sharpener. The invention relates to a knife sharpener Patent 336391, which is modified from the main patent so that its resistance significantly increased against change in shape during use while simplifying manufacture is. The modification consists in the fact that the supports carrying the wire spirals are made from are made of a common piece.

Auf der Zeichnung ist ein Ausführungsbeispiel in Ober- und Seitenansicht dargestellt. Die Halterteile c und d; welche für die als Schärfleisten dienenden, im vorliegenden Falle im Querschnitt dreieckigen Stahldrähte cc, b die Stützen bzw. Achsen bilden, sind Teile eines gekröpften, aus einem Stück bestehenden Bleches, das in der Mitte mit einem entsprechend breiten Schlitz e versehen ist und an beiden Enden in Befestigungslappen f, g ausläuft. Diese Lappen werden mit je einer Schraube an der Unterlage befestigt.In the drawing, an embodiment is shown in top and side views. The holder parts c and d; which form the supports or axes for the steel wires cc, b, which are used as sharpening strips in the present case, are triangular in cross-section and are parts of a cranked, one-piece sheet metal that is provided in the middle with a correspondingly wide slot e and on both Ends in fastening tabs f, g runs out. These flaps are attached to the base with one screw each.

Dadurch, daß die beiden Stützen Teile eines gemeinsamen Stückes sind, ist die gleichmäßige Entfernung der Stahldrahtspiralen voneinander auch für Massenfabrikation gesichert und *der Möglichkeit vorgebeugt, daß bei der Benutzung des Apparates infolge des Druckes ein Auseinanderdrängen der Stützstäbe stattfinden kann. Außerdem wird unter gleichzeitiger Materialersparnis die Herstellung erleichtert, indem das ganze Stützstück auf einmal und in beliebigen Mengen gleichartig hergestellt werden kann. Die Spiralen werden auf die Haltemeile c, d von der Seite her aufgeschraubt.The fact that the two supports are part of a common piece ensures that the steel wire spirals are evenly spaced from one another, even for mass production, and prevents the possibility of the support rods being pushed apart when the apparatus is used. In addition, while saving material at the same time, production is facilitated by the fact that the entire support piece can be produced in the same way at once and in any desired quantities. The spirals are screwed onto the holding mile c, d from the side.

Der Apparat kann in gleicher Weise auch als Sensenschärfer hergestellt werden, wobei die Befestigungslappen statt horizontal senkrecht liegen und seitlich an einem Stiel angebracht werden.The device can also be made as a scythe sharpener in the same way with the fastening tabs lying vertically instead of horizontally and laterally attached to a stem.
