[LM111403], Report from Arthur Edwin Kennelly, May 1889
Editor's Notes
####[page 198]####the Differences Between the Machine Described --Berly Specification, and the Edison Multi--- types.####1st The Berly machine has and claims two separate rings of iron ----- with wire for its armature. The Edison machine has only cylinder not of iron ---- as in the ---- drawings, but of iron wire pressed into ---p-. The iron disks in Berlys machine would be useless --- the Edison machine.####2nd There are turn ------- acts of ------ in the Berly machine and the poles opposite each others are always of opposite polarity. In the Berly diagrams these poles are made to ---- while the double ring armature remains fixed. In - the Edison machine there is only one set of fild's magnets the two coils on each side of the armature being wound to produce the same polarity in the iron pole piece between them. The armature not-- and the field magnets are fixed.####3rd The winding of the Berly iron zincs is in discontinuous sections separated apparently by -------d spaces. In the Edison machine the winding is continuous and of the --mmering type.####4th There are two commutators --- four brushesin the ---- machines only one commutator and two brushes on the Edison Machine.####[page 199]####(2) And generally the Berly machine claims and lays stress upon the use of the double armature the single armature being neither mentioned nor claimed, and the fact that the Edison Machine has but one armature that a wide ---and made of iron wire instead of iron plate is alone sufficient to separate it widely from the design, construction, and scope of the berly machines.####
