7.4.2 Cone Coupling

In this, two shafts may be coupled together by means of two flanges with conical surfaces (on

the inside of one and on the outside of the other) by virtue of friction. Here too, one flange is

firmly fitted to the driving shaft by means of a taper sunk key, whereas the other slides freely

over a feather key fitted to the driven shaft. The sliding flange may be moved by means of a

forked lever fitted into the groove provided on it. (Fig. 7.10).
