Holtz Machines and Wimshurst Machines. — In theinfluence machine, invented by Holtz (Berlin, 1865), ofwhich the Toepler-Holtz machine is a modiiication, thecharged bodies are simply sectors of paper fastened tothe back of the stationary glass plate. The carrier is therevolving plate itself. Instead of charging brushes, pointedstrips of paper are glued to the paper sectors. These pro-ject through windows in the stationary plate and makecontact with surface of the revolving plate. One form ofthe Holtz machine is shown in Fig. 192. 234 THE OUTLINES OF PHYSICS The Wimshurst machine is an influence machine inwhich both plates revolve but in opposite direction. Each. Fig. 192. plate bears a series of metallic carriers. (See Fig. 193.)For a full discussion of the action of this machine, seeElements of Physics, Vol. II, p. 108.
