Title
[D8456ZAD], Letter from Harry Ward Leonard to Thomas Alva Edison, February 7th, 1884
Editor's Notes
Yr 3 letter rcd. Ecnloses expense accts. Troubled by "ring of fire" running around armature of S dynamos; probably caused by cross between successive bars & makes them VERY hot. Had bad cross this morning & had to run spare machine; you MUST improve covering of the connections of the loops. TAE marg: "Send this to Soldan---this occurred at Fall River & must be looked into quickly & remedied."
