: & SILVE IRONCLAD I91IO — 1935 R ANNIVERSARY BUILT ON A PRINCIPLE AS BASIC AS THE WHEEL yet different from all other batteries The Exide-Ironclad completes a quarter century of service ber 9, 1910) The Electric Storage Battery Company, after more than two decades of developement and ex- perience, announced a new type of storage battery, designated the Exide- Ironclad. Built on the principle of the mesh that holds solids while permit- ting liquids to pass freely —a_prin- ciple that ranks with the wheel in antiquity and importance—the Exide- Ironclad marked an entirely new era in storage battery development. J vee twenty-five years ago (Septem- In the unique design of its positive plates, slotted rubber tubes retain the active material, while exposing it freely to the electrolyte — a type of con- struction which a quarter century of service has proved to be of excep- tional merit. For the first time in storage battery history, there was made available a battery that combined all four of the essential battery characteristics: high power ability, high electricial efficiency, extreme ruggedness, and long life. Starting from scratch, the Exide-Iron- clad had its way to make in the industry. Accepted by users at first entirely on their faith in its makers, year by year in actual service the Exide -Ironclad proved the merits of its construction and its many advantages, until today it holds a pre- eminent position of leader- ship in the industry. Users of Exide - Ironclad Batteries are numbered in the thousands. The majority of the submarine boats of the United States Navy, and many in foreign navies are propelled, when submerged, by Exide- Ironclad Batteries. These batteries are most widely used in marine service, both for routine and emergency oper- ation of all electrical auxiliaries. In fac- tories, mills, industrial plants, wharves and warehouses, they furnish the power for many thousands of electric indus- trial trucks and tractors. Deep underground, Exide-Ironclads propel storage battery locomotives used for gathering and main-line haul- age in coal and metal mines. Through mountains and under extinct volcanic crators in California, large fleets of Exide-Ironclads are helping in the con- struction of the greatest engineering projects now under way in the world. In addition, Exide-Ironclads operate electric and street trucks, industrial and railway switching locomotives. They help to make safe and comfort- able the journey of travelers, being most extensively used, not only in marine service, but for air-condition- ing, car-lighting and Diesel engine starting by our great railway lines. In 1910, the Exide-Ironclad was a battery such as engineers dreamed of. In 1935, it is a battery of depend- ability proved by a quarter century of actual service. Here are the features that, for 25 years, have contributed to safety at sea, to economy on every size and type of craft, and to efficient, low - cost materials handling service in electric industrial trucks : High Power Ability — providing great reserve power for conditions of ex- © cessive load. High Maintained Voltage —assuring unfailing normal operation of equipment e during periods of prolonged discharge.
