Show oo BETTER STORAGE BATTERIES For many years storage battery manufacturers have endeavored to find riu insulation 'nat would last the lire of the battery, eliminating the necessity neces-sity of reinsulation. Realizing that hard rubber was the bet known insulation and at the same time having the qualities necessary to resist the acids destroying it, all the battery manufacturers, more or less, having been working along that line. Bin they had formidable obstacles to overcome. Battery insulation, while having the best of insulating qualities must at the same time permit of a flow of the aeid through it in order to not hamper the chemical action of the battery bat-tery and thereby reduce the amperage capacity. Reduction of amperage would mean a sluggish starter. In order to overcome this difficulty in an ordinary manner it would be necessary for the battery to be built many times its original size, not only making the price prohibitive, but increasing the weight to such an extent that it would not be practicable. After the engineers for all the other battery manufacturers had given up hard rubber as an Insulator, the Wll-lard Wll-lard Storage Battery company continued contin-ued to work on it until finally their greatest hopes were realized, They 1 . . .1 1.1 L- 1 - sun eu uits piuuitrui ui iuuut'i insulation insula-tion by building special machinery I which would put 196,000 little threads running lengthwise through a hunk of hard rubber looking like a large bologna sausage, only square. This rubber was put through another machine ma-chine on the order of a chipped beef slicer and sliced off at the proper thickness in this corrugated sheets. This insulation, while still having all the qualities of the hard rubber, still permitted the flow of acid through the little threads and thereby kept the original amperage capacity of the inferior infe-rior wood insulation. This permits the shipping of a battery bat-tery from the factory completely built up and ready for use with the exception excep-tion of having the solution ad aed and being charged. As the plates do not commence to sluff until the acid is added, this bone dry battery could set for any reasonable length of time, and so long as the acid was not added there would be no depreciation In its value, while on the other hand with wood insulation it must be kept moist at all times, otherwise the wood will shrivel and crack, thereby necessitating necessitat-ing the complete reinsulation of the battery. As this necessitates the acid being added at the factory it means that by the time the consumer receives it it will be from three to eight months old. As the average life of a battery Is only two years, the automobile owner own-er can readily sec what a great improvement im-provement this is in the construction ot the automobile storage battery. This threaded rubber insulation has been tried out in tho hottest climates for the past three years and has proved to bo all that the Willard engineers engi-neers claimed for it Uncle Sam is now using immense shipments of these batteries. |
