Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Den Gegenstand der Erfindung bildet eine Abänderung des Werkzeugs zum Abziehen von Sensenblättern und sonstigen Schneidwerkzeugen nach Patent 139035. Dieselbe besteht in einer anderen Ausführung der harten Kugeln und ihrer Lager. In beiliegender Zeichnung stellen dar: Fig. 1 die Seitenansicht und Fig. 2 den Längsschnitt des vervollkommneten Werkzeuges. The subject of the invention is a modification of the tool for pulling off Scythe blades and other cutting tools according to patent 139035. The same exists in another version of the hard balls and their bearings. In the accompanying drawing show: FIG. 1 the side view and FIG. 2 the longitudinal section of the perfected tool.

Die Lagerblöcke j und j1 treten hier an die Stelle der kleinen Kugelpaare g. Der Lagerblock j1 ist in dem Körper α zwischen den zwei Handgriffen b verschiebbar angeordnet, zu welchem Zwecke im Körper ein Stift k1 und in dem Blocke j1 ein Schlitz I1 vorgesehen ist. Der andere Block j ist unbeweglich in dem Körper α mittels des Stiftes k befestigt. Die Kugeln e1 sind mit je zwei diametral entgegengesetzten kegelförmigen Dornen i versehen, welche in entsprechenden Lagern der Blöcke drehbar angeordnet sind. Die Stellung der Kugeln e1 gegeneinander ist mittels einer Stellschraube / regelbar, welche mit einer Gegenmutter h versehen ist und in Verbindung mit dem Lagerblock jl steht. Die Kugeln können sich somit nur in der durch die Spitzen bestimmten Achse drehen, wodurch offenbar die schädliche Reibung möglichst vermindert und die Schärfwirkung wesentlich erhöht wird.The bearing blocks j and j 1 take the place of the small pairs of balls g. The bearing block j is 1 in the body α between the two handles b displaceably arranged, for which purpose in the body, a pin 1 and k in the blocks j 1 I a slot 1 is provided. The other block j is fixed immovably in the body α by means of the pin k . The balls e 1 are each provided with two diametrically opposed conical mandrels i which are rotatably arranged in corresponding bearings of the blocks. The position of the balls e 1 relative to one another can be regulated by means of an adjusting screw / which is provided with a lock nut h and is in connection with the bearing block j l . The balls can therefore only rotate in the axis determined by the tips, which apparently reduces the damaging friction as much as possible and the sharpening effect is significantly increased.
