Abstract

Do you ever have trouble on your telegraph wires, owing to the failure of your batteries to supply sufficient current to the lines in wet weather? Do you believe it would be advantageous to have a battery which would be equally effective in wet weather as in dry weather? Do you consider that you could make a saving in your Telegraph Department by centralizing your main batteries and running say ten, twenty, thirty or more wires from one battery? Would this saving be increased if you were able to obtain a cell requiring absolutely no cleaning of parts? Would it be an advantage to you on the score of economy to run four, six or a dozen sounders from a single battery of two or three cells? If you answer these questions in the affirmative you can get the battery you want by corresponding with us. We have just commenced the manufacture of a cell, perfected recently by Mr .Edison, which possesses the following features : Internal resistance twenty-five one-thousandths (.025) of an oh, One hundred and fifty (150 of these cells in series have a combined internal resistance of only three and three-quarter (3 ¾) ohms, which means practically that all the current goes to the line, regardless of conditions of weather. Local action less than one-half of one percent., which means that we obtain from this cell more than ninety-eight percent (98%) of the theoretical amount of power contained in the zinc. There is absolutely no polarization. The parts of the cell never require cleaning. We use a simple caustic potash solution and manufacture the potash in sticks, so that renewal means simply placing one of these sticks in a cell and pouring in the requisite quantity of water. The renewal of parts when required is readily effected. For Main Batteries on Telegraph Lines we make cells of different ampere capacities which have a life dependent upon the work done of from six weeks to one year and over. In short we manufacture the most perfect commercial primary battery that has ever been placed in the market. For a closed circuit work it has absolutely no equal. For open circuit work it has absolutely no superior. We will be very pleased to correspond with interested persons and give further particulars with which it is unnecessary to burden this communication
