This rotating shaft passesthrough and is covered by the flexible sheath (N, Cut No. 1),which is attached to the head-piece (L) and does not rotate. The sheath (N) and driven shaft passing through it com-pose the flexible icorking arm of this Engine, which is one ofits characteristic and peculiar parts. The shaft joins the stem, which passes throughthe head-piece (L) and carries the driven pulley (M), and at the other end is joined tothe mandrel of the hand-piece, the extreme end of which is form
