Description

Minenschärfer Die vorliegende Neuerung betrifft einen Minenschärfer, insbesondere für auswechselbare Langschreibminen (Bleiminen, Farbstoffminen, Schiefer etc.).Mine sharpener The present innovation relates to a mine sharpener, especially for replaceable long writing leads (lead leads, dye leads, slate Etc.).

Die Neuerung besteht in einem besonders zweckmässigem Gerät zum Schleifen von Minen, die besonders spitz sein müssen, d. h. solche Minen, die durch technische Zeichner, Künstler und Graphiker Anwendung finden.The innovation consists in a particularly useful device for grinding of mines that have to be particularly pointed, d. H. such mines by technical Draftsmen, artists and graphic designers find application.

Die Neuerung ist durch eine konische Hülse gekennzeichnet, deren innerer Mantel eine endlose Schleiffläche besitzt. Weitere Merkmale sind der nachfolgenden Beschreibung im Detail zu entnehmen.The innovation is characterized by a conical sleeve, the inner one Coat has an endless grinding surface. Other features are the following Description can be found in detail.

In der Zeichnung ist in Fig. l teilweise aufgebrochen, geschnitten im Aufriss der Minenschärfer veranschaulicht.In the drawing, FIG. 1 is partially broken open, in section illustrated in the elevation of the mine sharpener.

Fig. 2 zeigt den Schleifkonus Fig. 3 zeigt das Außengehäuse Fig. 4 ist die Draufsicht auf Fig. 1 Fig. 5 entspricht der Fig. 1 und veranschaulicht das Ansetzen der zu spitzenden Mine samt Minenträgerstift. Fig. 2 shows the grinding cone Fig. 3 shows the outer housing Fig. 4 is the top view of FIG. 1 Fig. 5 corresponds to Fig. 1 and illustrates the attachment of the lead to be sharpened, including the lead carrier pin.

Fig. 6 veranschaulicht in perspektiver Darstellung den Gebrauch des Gerätes.Fig. 6 illustrates in perspective the use of the Device.

In der Zeichnung ist das Gehäuse/die Außenhülse des Minenschärfers mit 1 bezeichnet. 2 ist die konische Hülse mit Schleifmantel 3. Die zu schleifende Mine trägt das Bezugszeichen 4, der Minenstiftträger ist 5, der Sammelraum für den Abfall 6 ist das Gehäuse l, mit 7 bezeichnet, 8 ist die Schleiffläche.In the drawing is the housing / outer sleeve of the lead sharpener denoted by 1. 2 is the conical sleeve with grinding jacket 3. The one to be ground Mine bears the reference number 4, the lead pencil carrier is 5, the collecting space for the Waste 6 is the housing 1, labeled 7, 8 is the grinding surface.

Der Innenmantel 3 besteht aus einer endlosen Schleiffläche. Diese Schleiffläche kann auf mannigfaltige Weise gebildet sein. Die Schleiffläche 8 kann z. B. durch Aufrauhen des Innenmantels der konischen Hülse 2 entstehen. Die Schleiffläche 8 kann aber auch dadurch gebildet sein, daß ein körniges Schleifmittel in den Innenmantel der konischen Hülse 2 an die Oberfläche tretend, eingebettet ist. Ferner kann die Schleiffläche 8 aus Schmirgelpapier oder Leinen vorgesehen sein, das als Mantel 3 stoffschlüssig mit dem Innenmantel des Konusses 2 verbunden ist. Man kann, wie in Fig. 6 dargestellt ist, durch Rotieren des in der rechten Hand gehaltenen Stiftes 5 die Mine 4 beliebig anspitzen, indem man sie leicht gegen die Schleiffläche 8, welche die Bewegung begrenzt, drückt, wobei das Schleifgerät in der linken Hand gehalten wird. Der Winkel des Konusses 2 des Schleifmantels 3 beträgt gegenüber der Längsachse des Gerätes etwa 5 bis 15 Grad.The inner jacket 3 consists of an endless grinding surface. These The grinding surface can be formed in a variety of ways. The grinding surface 8 can z. B. arise by roughening the inner jacket of the conical sleeve 2. The grinding surface 8 can also be formed in that a granular abrasive in the inner jacket the conical sleeve 2 stepping to the surface, is embedded. Furthermore, the Sanding surface 8 made of emery paper or linen can be provided as a coat 3 is firmly connected to the inner jacket of the cone 2. You can how shown in Fig. 6 by rotating the pen held in the right hand 5 sharpen lead 4 as desired by you easily against the The grinding surface 8, which limits the movement, presses, the grinding device in left hand. The angle of the cone 2 of the grinding jacket 3 is about 5 to 15 degrees in relation to the longitudinal axis of the device.
