A Brunor perfected dynamo is made without regard tocost of material or of labor, and is so designed that it per-forms the regular rated work at a much slower speed thanhas been possible heretofore. It has its parts so formed orarranged as to prevent all the troubles which many yearsexperience has shown were liable to happen to electricalmachinery. A Brunor perfected dynamo has many specialadvantages which cannot be found in others. The field 12 THE PRACTICAL ELECTROPLATER. magnets are composed entirely of the best wrought iron,each magnet being forged in a single piece and set deeplyinto the base, thereby securing great solidity and amplemagnetic contact. (See Diagram No. i.) The space forwire on these magnets is perfectly cylindrical, in the form of. Brunors Perfected Dynamo. Speed. Minute. ,2oo Revolutions Per an ordinary spool (see Diagrams Nos. 2 and 3), therebyinsuring smooth and perfect winding of the wire, and thecore is short, permitting the shaft of the machine to be lowenough to free it from vibration. By this constructionthe neutrality or freedom of the base from magnetism issecured, and there is no tendency to leakage. This makes BRUNORS PERFECTED DYNAMO. ^3 the Brunor machine far superior to all those in which thebase is made to serve as one of the pole pieces, as the bear-ings then become magnetized and make the shaft bind. The armatures possess several improvements. Theyare sufficiently large in diameter to obtain slow speed(see illustration of armature), and are so designed that the
