Cane sugar; a textbook on the agriculture of the sugar cane, the manufacture of cane sugar, and the analysis of sugar-house products. lower end of the spindlerotating in bearings surrounded by rubber buffers. The modern sugar centrifugal machine dates from Westons patent(3041 of 1867 ; patent 63770, 1867), and was developed by him whenengaged as an operating engineer in the Hawaiian Islands. His machine,as shown in his patent, and from which the very latest machines only differin detail, combined freedom of oscillation with a solid stationary suspendedspindle supporting a hollow rotating spindle, to which is attached the per-forated basket. His patent did not claim suspension, but only the specialmeans of suspension,* and he is in no wise to be considered the inventor of * A provisional patent issued to Johnson as agent (418 of 1852) mentions a hollow spindle, but gives no details. 410 CHAPTER XX the suspended machine, the credit for which is due to Bessemer, and to whose design the latest types of soHd spindle machines tend to revert.

Themachine is suspended from a girder, CR, by the socket , which containsan india-rubber or elastic bushing, , in which the soHd stationary is held. At the lower part of this spindle is placed a series of washers,, supported by the screw nut The outer hollow rotating spindle THE SEPARATION OF THE CRYSTALS 411 carries the driving pulley and the basket B., and is supported by a shoulderon the washers. The outer casing or curb, which serves to collect themolasses, is shown at , the molasses flo\s-ing away by a spout. Thecentral valve, , sliding on spindle, also forms a part of the patent the Hepworth machine (patent 3375 of 1871 ; patent 82314,1868)the whole machine was suspended from a baU and socket joint.
