STORAGE BATTERY sidsa e The story of a remarkable storage battery invention and what it is doing for Motorists. In the fall of 1917 readers of national magazines read about a new Willard, a Still Better Willard, a Willard with/an entirely new idea in battery construction—Threaded Rubber Insulation. ! The Still Better Willard was not an experiment—for two years be- fore that announcement a car builder put it on 35,000 cars. Many of those first Willard Batteries with Threaded Rubber Insulation are still in use after four years. What is the Secret of Threaded Rubber Success? Insulation had always been the big problem with any storage bat- tery. Ordinary materials wore out before the battery plates did. Re-in- sulation was bound to come soon or late, and when insulation began to break down the plates were injured. But Willard, for the first time found a practical way to use rubber, the one ideal insulating material, by piercing each rubber insulator with 196,000 tiny threads to permit passage of the electrolyte. Ask for booklets ““The Wick of the Willard,” and “A Mark with a Meaning for You.” You ought to be posted on batteries and battery insulation, so that when you need a new battery you’ll be sure of the best your money can buy.
