Holtzer battery

The Holtzer Cylinder Battery.

The desire to obtain an open circuit battery of large generating power and one which should quickly recuperate led to the construction of the Holtzer cylinder battery of the Leclanche type, by Messrs. Holtzer & Cabot, of Boston, and shown in perspective in Fig. 1 and in section in Fig. 2.

Fig. 1. — the Holtzer Battery.

As will be seen on referring to the cuts, the battery consists practically of two parts only, as the cylinder, zinc and connector form the first part, they being collectively united and forming one piece alone; the second part being the glass jar.

The cylinder, resting on the top of the jar, forms by its weight a well-sealed joint, thus preventing evaporation. There are no fragile parts to be easily broken, but one strong heavy carbon of cylindrical form, having a binding post well secured to it and thoroughly protected from salts. The zinc is separated from the cylinder by a porcelain piece of wedge shape to secure a close fit. Thus is presented one of the simplest and most practicable forms of Leclanche battery obtainable.
