Description
Bleistiftschoner mit im Innern angebrachten Rauhungen zum Auschärfen der raine. Gegenstand der Erfindung ist ein Bleistiftschoner mit im Innern angebrachten Rauhungen zum. Anschärfen der Mine. Die Erfindung besteht darin, daß in der Wandung des Bleistiftschoners etwa längsachsig verlaufende Schlitze und Bohrungen vorgesehen sind, durch die beim Anspitzen der Mine der abgeschabte 1-Iinenstaub seitlich herausfällt.Pencil protector with roughening on the inside for sharpening the raine. The subject of the invention is a pencil protector with attached inside Roughening for. Sharpening the mine. The invention consists in that in the wall the pencil protector is provided with slots and bores running approximately along the axis through which the scraped-off 1-line dust falls out to the side when the lead is sharpened.
Der neue Schoner ist in der Zeichnung dargestellt. Es zeigen: Abb. i die Anordnung im Gebrauch als Bleistiftspitzer, Abb. 2 sie als Schutzhaube für die hergestellte Spitze, Ab@b. 3 und q. Längsschnitte in verschiedenen Ebenen, und Abb. 5 einen Querschnitt nach 5-5 der Abb. 3.The new schooner is shown in the drawing. It shows: Fig. i the arrangement in use as a pencil sharpener, Fig. 2 it as a protective hood for the tip made, Ab @ b. 3 and q. Longitudinal sections in different planes, and Fig. 5 shows a cross section according to 5-5 of Fig. 3.
Der Körper i der Vorrichtung läuft in eine abgerundete Nase 2 aus, in welcher sich eine verhältnismäßig dünne, in Achisrichtung verlaufende Bohrung 3 befindet. Am anderen Ende ist bei 7 eine nahezu zylindrische Bohrung vorgesehen. Zwischen diesen beiden Bohrungen von verschiedenem Durchmesser befinden sich die kegelförmig verlaufenden Abschabefläehen 8 und 9.The body i of the device ends in a rounded nose 2, in which there is a relatively thin, axially extending bore 3 is located. At the other end, an almost cylindrical bore is provided at 7. Between these two holes of different diameters are the conical scraping surfaces 8 and 9.
In dein Körper selbst sind die Schlitze io angeordnet, die sich in Längsrichtung erstrecken und an dem der Spitze zugekehrten Ende in eine Erweiterung oder Bohrung i i auslaufen. Ton dieser Erweiterung aus gehen wieder Nuten 12 im Innern der Spitze zur Bohrung 3 am vorderen Ende. Diese Nuten haben nicht die gleiche Tiefe auf ihrer ganzen Länge, sondern nehmen in Richtung gegen die Spitze hin ab. Sie dienen dazu, ilie abgeschabten Späne nach rückwärts zu schaffen und durch die Löcher i i ausfallen zu lassen. Dadurch-, daß die Schlitze i2 an dem einen Ende tiefer sind, wird diese Förderung der Späne von der Spitze nach dem rückwärtigen Ende der Nuten hin erleichtert. Die Schlitze io dienen wohl auch dem gleichen Zweck der Ausstoßung der Späne, verleihen jedoch auch der ganzen Anordnung eine Nachgiebigkeit, um so mehr, als sich an diese Schlitze die Spalten 13 ansetzen, die durch den Wulst 6 des zylindrischen Körpers 5 hindurchgehen. Dadurch wird die Haube nachgiebig gegen die Außenfläche eines Bleistiftes gedrückt und in Reibung mit ihm erhalten.The slits io are arranged in your body, which are located in Extend longitudinally and at the end facing the tip in an extension or bore i i run out. Sound of this extension go out again grooves 12 in Inside the tip to hole 3 at the front end. These grooves are not the same Depth along its entire length, but decrease in the direction towards the tip. They are used to move the scraped chips backwards and through the To drop holes i i. In that the slots i2 at one end are deeper, this will promote the chips from the top to the rear End of the grooves relieved. The slots io probably also serve the same purpose the expulsion of the chips, but also give the whole arrangement a resilience, all the more so as the gaps 13 adjoin these slots, which are caused by the bead 6 of the cylindrical body 5 go through. This makes the hood pliable against pressed the outer surface of a pencil and kept in friction with it.
