die Keilspitze sonst zugeschärft und nach den glatten Seitenflächen hin abgerundet war, wird nach der erfindung der Meissel so ausgebildet, dass er nicht in eine zugeschärfte Kante ausläuft, sondern eine Stirnflächo mit mehreren Schneidkanten aufweist, wobei die Kanten und Rillen der Meissetvordernäche in der Verlängerung der Kanten und Rillen der Seitenflächon liegen. Der so geänderte Meissel eignet sich vornehmlich zum ersten Ein-

sie eine einzige fortlaufende Schneidkante bildet.
Man wird deshalb die Arbeit mit einem Meissel beginnen, der eine sehr breite Vorderfläche besitzt und im Masse der Lochbildung zu Meisseln mit weniger breiter Stirnfläche und schliesslich zum Meissel mit einer scharfen Spitzenkante übergeben.
Auf der Zeichnung ist in Fig. 1 eine Seitenfläche und in Fig. 2 die Vorderfläche des neuen Meissels dargestellt. Fig. 3 zeigt den unteren Teil des Meissels von der Schmalseite gesehen.
Der Keil des Meissels ist mit a, dessen Schaft mit b, die seitlichen Schneidkanten mit ('und die Vorderfächo mit d bezeichnet. Diese Vorderfläche bildet aber vorliegendenfalls nicht eine einzige der Meisselbreito nach sich erstreckende Schneide, sondern weist mehrere aufrechte Schneiden m auf.

Wedge chisels for rock drilling machines
EMI1.1
the wedge tip was otherwise sharpened and rounded towards the smooth side surfaces, according to the invention the chisel is designed so that it does not run out into a sharpened edge, but has a face with several cutting edges, the edges and grooves of the Meisset front surface in the extension of the Edges and grooves of the side surface lie. The chisel modified in this way is primarily suitable for the first
EMI1.2
it forms a single continuous cutting edge.
Work will therefore begin with a chisel that has a very wide front surface and, as the hole is formed, it is transferred to chisels with a smaller front surface and finally to a chisel with a sharp point edge.
In the drawing, a side surface is shown in FIG. 1 and the front surface of the new chisel is shown in FIG. 2. Fig. 3 shows the lower part of the chisel seen from the narrow side.
The wedge of the chisel is marked with a, its shaft with b, the lateral cutting edges with ('and the front surface with d. In the present case, however, this front surface does not form a single cutting edge extending over the width of the chisel, but has several upright cutting edges m.
