This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1893 edition. Excerpt: the construction of fan motors that could be run by low potential currents such as are generated by primary batteries. In the accompanying illustration is shown one which has been designed for a current of two amperes at one and one-half volts. Such a current will run a seven inch four bladed fan at 1,000 revolutions per minute. This fan motor with the battery which consists of three Edison-Leland cells, placed in a well made and nicely furnished oak box requires but little space and is easily moved. The capacity of the battery is 150 ampere hours with practically no loss when the motor is not in use. The armature of the motor, as suggested by the motor's name, is entirely enclosed in an iron box with a glass window at one end through which the brushes and'commutators may be inspected. ts bearings are self oiling and carry on their own lubrication without loss of the lubricant. The oil wells need refilling only when the battery is recharged. This arrangement, as well as the enclosing of the motor, insures the neat use of the fan without any attending dirt or oil. It may be placed anywhere about the room and makes an attractive ornament. Among the many advantages of this iron clad motor is its compactness, safety, noiselessness, cleanliness, and efficiency. For country villas, city residences, steamer cabins, etc., the fan will be greatly appreciated. The cost of operating the machine amounts to about two and three-fourth cents per hour and any repairs or adjustments are quickly and easily made by sliding the glass window which covers the end of the armature. These fan motors and batteries are manufactured by the Edison Manufacturing Company, 110 E. 23rd St., New York. The new Whitney instruments for alternating current work...
