DISCHARGER
, or Discharging Rod, in Electricity, consists of a handle of glass or baked wood, A, and two bent metal rods BB, terminating in points, and capable of being screwed into the knobs DD, which | move by a joint C, fixed to the handle A. Thus it may be used either with the points or balls, as occasion requires; and by being made moveable on a joint, it may be applied to larger or smaller jars at pleasure. By bringing one of these knobs or points to one coated side of a charged electric, and the other to the other side, or to any conductor connected with it, the communication is completed between the two sides, and the electric is discharged.
For the description and use of an Universal Discharger, by Mr. Henly, with which many curious experiments may be performed, see Cavallo's Electricity, pa. 164.
