The Curt Battery.
Curt W. Meyer, the manufacturing electrician at 357 Fourth ave., this city, has recently invented and constructed a battery worthy of special mention. The battery, as shown in the illustrations, is very compact and neat in appearance, and possesses many excellent features which we shall describe. The principles of the Grenet battery have been adhered to, tint in many respects changes and detailed improvements have been made. One special idea is the construction of the battery so that equal parts do correspond exactly, and each part can be duplicated, in case of need, at low cost; further that the exact amount of current required to develop the full illuminating power of the lamp will be furnished, and the carbon filament in no danger from too strong a current. Various exciting fluids can be applied without danger to any part of the battery. The carbons are corrugated on their inner surface, thus enlargeing and also roughening it, and are screwed on broad flanges, thus forming a perfect connection, and in case one of them should be broken, a new one can be attached immediately. The glass jar is square below and round on top, and is capable of holding almost twice the amount of fluid as an ordinary Grenet. The jar is well molded, and has no metallic ring cemented thereon, but a groove around the upper part, holding an elastic rubber ring, over which a solid rubber cap fits tightly. A more continuous current is produced by using bi-sulphate of mercury and sulphuric acid mixed, instead of bi-chromate of potash, without fear of injuring battery jar mountings. The electrodes are fastened to the rubber cap, and all metallic parts are nickel plated and highly polished. An exact duplicate of the single parts can be had at any time, at low cost, which is quite a convenience particularly to surgeons and physicians. The Curt Battery No. 1a is of a superior finish, the surfaces connecting with the carbons are platina covered, and the sliding rod for the zinc is jointed — a decided convenience in packing the battery for transportation.
These batteries will replace any office battery for every-day use to great advantage on account of their power and cleanliness. A single cell will be sufficient to operate any medical induction coil or Faradic instrument. A greater number of cells combined, will furnish an excellent and clean cauterizing battery, will most conveniently charge a storage battery, or will operate the electromagnetic mallet satisfactorily.
