Text Appearing Before Image:
the effect of the wheel. H 4 K-IE S Fig, 50.
Text Appearing After Image:
Fig. 51. Fig-. 51 is a side view ot the wheel, show-ing one manner of mounting the disk and 158 Rotating Efftxts. its connections. The same figures applyto the parts as in the preceding figure.J/iVare the wires leading to the coil, /* isa pulley on the shaft whereby the rotarypower may be applied. The wires on theface of the disk are not shown, as theywould impair the clearness of the diagramunnecessarily. The greatest danger in the operation ofsuch a piece of apparatus will be the ten-dency of the high tension spark to wanderwhere it is not wanted, and to take shortbut forbidden paths back to the coil. How-ever, care and perhaps experiment willprove the remedy. It will be noticed byreference to Fig. 49 that a circle has beendrawn almost bisecting two of the tube-holders. This circle represents a circle ofdanger, and where a thin material has beenused for the disk, the disk may very wellbe reinforced by a piece of stouter cardcemented on its face. The disk, whether of wood or of paste
