In general plan ofconstruction and arrange­ ment the apparatus essentially the same as 45 that described and shown patent granted to September 22, 1896, No. 2—that say, tapered con­ tracted toward the periphery form a narrow trough which the fluid confined 70 when the drum rotated. In order insure the proper immersion of the projections into the fluid compensate io for wear and the same time secure a yielding pressure between the fluid and the disk, desirable employ for the disk some form spring connection support which will exert force tending force in 15 contact with the fluid. I have also devised certain details con­ struction which add the efficiency and prac­ ticability the apparatus which will more conveniently described reference the ae- 20 companying drawings. central vertical section 25 the improved circuit-controller Fig. The circuit connections will described connection with Fig. Its teeth are arranged that two are simul­ taneously contact with the conducting 85 fluid, but come into the same successively. convenient way accomplish this form racks the arms and 125 provide pinion engagement therewith.
