The Continuous Electrophorus —The most efficient elec-trical machines are those which work by induction andgive a nearly continuous supply of electricity, as theTSpler-Holtz machine, so called from its inventors. () In this instrument there is a large stationary glassplate, known as the fi<h1 phitc, on the back of whichare pasted pieces of varnished cardboard to act as in-ductors. In front of the field plate is a smaller revolv-ing plate bearing circular pieces of tin foil, called cnr-Tiers. placed at equal intervals, each carrier having ametallic button at its center. From each inductor on theback of the fixed plate is a curved metallic arm whichreaches over the revolving plate and holds a small tinselbrush which sweeps over each carrier as it passes Fig. 85.—Topler-Holtz Machine. In front of the revolving plate is seen a metal rod bear-ing metallic combs which approach near to but do nottouch the glass, each comb having its central tooth re-placed by a tinsel brush. This may be known as theneutralizing conductor. Below this may be seen twohorizontal rods known as discharging conductors, andalso bearing metallic combs.
