Title
[NM016ABF], Technical Note, Thomas Alva Edison, May 21st, 1881
Editor's Notes
huh? Commutator connection junk, then third image is two really nice drawings of the concentric ring endplates for connecting armature bars. These don't use the metal forks as in some drawings; actually look like wire connections. 4th image is disk armature showing placement of radial bars. This is a different type of construction than what they've just built; it's like the printers chase entry few days prior, with flat slabs arranged around the hub (rather than attached to face of disk.
