. Modern mechanism, exhibiting the latest progress in machines, motors, and the transmission of power, being a supplementary volume to Appletons' cyclopaedia of applied mechanics . Fi(.. 01 —Matlier u dynamo. Fig. 62.— Manchester ? dynamo. Zurich, Switzerland, closely resembles the J3L. Fig. —Brown The Broum Dyimmo (Fig. 63). designed by C. E. L. Brown, of the Oerlikon Works, near Manchester type (Fig. 62), but is even more, The illustration ixpresents the ma-chine designed to give 450 amperes at a 115volts at 350 revolutions per minute. The di-mensions of it are as follows: Diameter ofring, 61-4 cms.: length of ring, 55 cms.; lengthof shaft, 19G cms.; total height of machine,120 cms.; wrought-iron cores, (JO long, 40cms. diameter; cast-iron yokes, 30 tliiek,44 cms. broad; diameter of pulley, 60 cms.;total weight, tons; ampere turns at full ex-citation, 35,000. The armature of Browns dynamo differsin one respect from those of the preceding ma-chines. It is built up of thin iron disks, , instead of being toothed as in the Paci-notti forms, are perforated with a peripheralseries of holes, as in the Wenstrom dynamo, toreceive the armature conductors, which lie thus about 1 mm. below the periphery.
