Details
An unusual pattern electro-static induction machine,
unsigned, the winder driving a 15in. (38cm.) dia. glass plate with friction pads, supported between twin ebonised columns of unequal length, with glass insulators supporting the axis for the 20in. (51cm.) dia. vulcanite central driving plate, the glass insulators supporting the dumbell-shaped lacquered-brass conductor -- 37in. (94cm.) long, with suspended comb, one conductor with adjustable comb to the lower glass plate and adjustable brass conductor (insulated handle missing), the whole mounted on a mahogany stretcher stand, overall height -- 40in. (101.5cm.) (with part damaged vulcanite insulating panel)
