Die Erfindung ist auf der Zeichnung in den Fig. i bis 3 veranschaulicht.The invention is i illustrated in the drawing in FIGS. To 3.
Fig. i stellt die Vorderansicht dar, Z, Filr. 2 eil1C1-1 Schnitt nach Linie A-B in Fig.Fig. I represents the front view, Z, Filr. 2 eil1C1-1 section along line AB in Fig.
