PATENTAMT.PATENT OFFICE.

Die auf beiliegender Zeichnung dargestellte Messerputzmaschine unterscheidet sich von den bisher bekannt gewordenen dadurch, dafs die beiden die Putzscheiben tragenden Prefsplatten unabhängig von einander mittelst besonderer Zapfen im Rahmen der Maschine gelagert sind. Infolge dessen kann der Durchmesser der Putzscheiben fast um die Hälfte verringert werden. Mit dieser Maschine ist ferner eine Vorrichtung verbunden, durch welche der Druck der Putzscheiben gegen einander geregelt und die Leistung derselben wesentlich erhöht werden kann.The knife cleaning machine shown in the accompanying drawing differs from the previously known by the fact that the two Prefsplatten carrying the cleaning disks are stored independently of each other by means of special pins in the frame of the machine. As a result, the diameter of the cleaning discs can be reduced by almost half. A device is also connected to this machine, through which the pressure of the cleaning discs regulated against each other and the performance of the same significantly increased can.

Jede Prefsplatte ist mit ihrem an der Aufsenfläche angebrachten Zapfen b in einem Ständer c gelagert. Letztere ruhen auf einer Grundplatte d und können mittelst eines an ihrem oberen Ende angebrachten Schraubenbolzens gh nach Bedarf zusammengespannt werden, so dafs auch die Putzscheiben f durch Vermittelung der Prefsplatten α und der elastischen Ringe e so fest gegen einander geprefst werden, dafs die der einen Prefsplatte mittelst der Handkurbel k ertheilte Drehbewegung auf die andere durch Reibung übertragen wird. Aufser zur Regelung des Druckes der Putzscheiben f auf einander dient der Bolzen g gleichzeitig als Stütze für das zu putzende Messer. Die elastischen Ringe e sind, wie Fig. 3 zeigt, mit radialen Einkerbungen e¹ versehen, um ein besseres Anschmiegen der vorzugsweise aus Leder angefertigten Putzscheiben f an die zu reinigenden Flächen der Messerklingen zu ermöglichen; auch empfiehlt es sich, die einander gegenüberliegenden zahnartigen Flächen der elastischen Ringe e nicht in einer Ebene, sondern in Wellenform anzuordnen (Fig. 3), wodurch die Leistungsfähigkeit der Maschine beträchtlich erhöht wird. Die auf die Putzscheiben f einwirkenden elastischen Ringe e sind in passende Vertiefungen der ebenfalls etwas nachgiebigen Prefsplatten a so weit eingelassen, dafs im wesentlichen nur der zahnartige Theil derselben aus den Prefsplatten vorspringt.Each Prefsplatte is mounted with its pin b attached to the outer surface in a stand c . The latter rest on a base plate d and can be clamped together as required by means of a screw bolt gh attached to their upper end, so that the cleaning disks f are also pressed so tightly against one another by means of the pressing plates α and the elastic rings e that those of the one pressing plate by means of the hand crank k ertheilte rotary motion to the other is transmitted by friction. In addition to regulating the pressure of the cleaning disks f on one another, the bolt g also serves as a support for the knife to be cleaned. As FIG. 3 shows, the elastic rings e are provided with radial notches e ¹ in order to enable the cleaning disks f , which are preferably made of leather, to nestle better against the surfaces of the knife blades to be cleaned; It is also advisable to arrange the opposing tooth-like surfaces of the elastic rings e not in a plane, but in a wave shape (FIG. 3), as a result of which the performance of the machine is considerably increased. The elastic rings e acting on the cleaning disks f are let into matching depressions in the likewise somewhat yielding Prefsplatten a so far that essentially only the tooth-like part of the same protrudes from the Prefsplatten.

Claims

Patent Claims:

Are stored 1. A knife Shine, in which the two the cleaning discs (f) carrying Prefsplatten (a) independently of each other by means of special, attached to their highly surface spigot (b) in column (c), which attached with the aid of a at its upper end , if necessary, screw bolts (gh) serving as knife supports can be clamped together in order to regulate the pressure of the cleaning disks (f) against each other, so that the rotational movement imparted to one of the prefs plate (a) is also transmitted to the other.

2. In the case of a knife cleaning machine of the type specified under 1., the one inserted near the edge between the Prefsplatten (a) and the cleaning disks (f) , from one

rings (e) made from resilient fabric , which are provided with radial notches (eV ) on the sides facing each other, in order to ensure that the cleaning discs (J) nestle better against the surfaces of the knife blades to be cleaned.

With a knife cleaning machine the under ι. and 2. indicated type the arrangement of the elastic rings (e) in such a way that the joint created between the two represents a wavy line, for the purpose of increasing the efficiency of the machine.

For this purpose ι sheet of drawings.
