The machine isalso Drovided with two drums, 1 and ,?, turning upon the shafts, i and/. These shafts, to-getheV with the magnets, a and b, which they also serve to support, stand still, while thedrums may be rapidly revolved around the magnets and out of contact therewith. It will 598 OEE-DEESSmG MACHINERY. be noticed that the rnagnet occupies a sector of the drum, the proportions being such that,approximately, one third of the periphery of the drum is within the influence of the magneticfield, while the upper two-thirds is outside of the field and removed from the nuignetic influ-ence. The magnet is so constructed as
