Description The four separately removable jars are contained in a case of shining wood with four sections and with a metallic bottom. The metallic bottom is connected to a hook. The inner armatures are connected in parallel by four conductors connected with screws, so as to allow the use of every capacitor separately. | |||

Description The two jars have the outer armatures made of a nickered brass sheet, with connections for the lateral conductor of resonance. The first rectangular circuit, made of a thick aluminium wire, includes the first Leyden jar and the spark gap movable by hand with its ebonite support. The second circuit is formed by the second jar and by two parallel aluminium wires supported by an ebonite support. Against the latter and perpendicularly to it, there is a third conductor movable by an ebonite handle. If the conditions for the oscillating discharge are satisfied, we obtain a close oscillator and a close receiver, that can become tuned by shifting the mobile conductor. In that case, the discharge in the adjustable spark gap placed on the armature of the second capacitor, will correspond to the discharge of the first capacitor. | |||
