Fig. 4 der Zeichnung stellt die Vorderansicht des exzentrischen Meissels, Fig. 5 einen Gewindemittellängsschnitt durch denselben, Fig. G eine Druntersicht dar und Fig. 7 -11 zeigen mehrere, in verschiedenen Höhenlagen durch das Meisselblatt geführte Querschnitte.
Wie ersichtlich, sind an der schmiilcron Meisselseite unmittelbar an der Stelle I (Fig. 4) beginnend, wo die andere Hälfte breiter als diese wird, entsprechende Ver- sttirkungen v im Materiale vorgenommen, wodurch eine Gewichtsausgleichung beider Meissel-

4 of the drawing shows the front view of the eccentric chisel, FIG. 5 shows a thread center longitudinal section through the same, FIG. G shows a bottom view, and FIGS. 7-11 show several cross-sections guided through the chisel blade at different heights.
As can be seen, on the Schmiilcron chisel side, beginning immediately at point I (Fig. 4), where the other half becomes wider than this, corresponding reinforcements v are made in the material, whereby a weight compensation of both chisels
