This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1884 edition. Excerpt: ...made for physical and chemical laboratories with armatures for quantity and electromotive force to be used in change. SO. The Gramme Machine for Hand or Foot Power. The Cabinet 31achines. Brequet, of Paris, makes machines of this style which are intended for an always-ready apparatus for instruction in physics and chemistry, and for medical uses. They are made of a strength equal to eight Bunsen cells coupled in series. The first one of this kind, Fig. 128, had a large permanent magnet, and supplied a current equal to only three Bunsen cells. They were soon replaced by the form shown in Fig. 129, the magnets of which were much stronger. These latter soon after received the present form for foot-power shown Gramme Machine for Hand-Power. in Fig. 130. The chief characteristic of the present machines of this type is the peculiar form and construction of the permanent magnet. This consists, according to Professor Jamin, of Paris, of a great number of thin steel plates, tightly pressed together at the sides by two clamps, but allowed to slightly diverge at their ends. These ends terminate in massive Fio. 130. shoes, which act as poles to the magnet, and nearly completely embrace the armature. The brushes bear upon the collector-bars as in the previously-described Gramme machines, i. e., on the neutral line between the poles. Jamin found by a series of experiments the best form and construction of a steel, laminated magnet, and this construction has received his name. SI. The Gramme Large DynamoElectric IVJachine for Galvanoplastic Purposes. As long as steel magnets were applied in machines for the production of the electric current, the strength of the current could not be much increased, as it was necessary to keep within dimensions similar to those...
