Description The four piles of prismatic shape are contained in a beech wood case, thus has two lateral columns destined to held the mobile system of the zinc-carbon groups. The immersion happens without complicate devices, similar to the device of the Grenet’s pile. During the descent, the group that is immerses stops on two elastic pads, that avoiding the risk of breaking in the case in which the operator should leave the control ring. In the rest position the four containers are kept covered with a glass plate. | |||

Description It is formed by a cylindrical vase with a central narrowing. In the upper side we place a cylindrical zinc plate immerged in a zinc sulphate solution. A copper electrode is immerged in a solution of sulphate copper. It rises from the lower side of the vase and its form is partly a spiral with an insulating protection on its top. The cell supplies a constant current for a long time. | |||

Description It is formed by many disks of silver or golden paper held by an ebonite bar, and pressed between two terminal armatures. These hold a hook and a binding post (to hang the cell). The cell is divided into two parts by a protruding aluminium disk that is used to block it in the metallic container. The internal surface of the container presents a seam that obliges the cell ends to hang inside and prevents them from short circuit. | |||
