[LB012277], Letter from Thomas Alva Edison to Edison Machine Works, Charles L Dean, May 11th, 1882

Editor's Notes

Your two letters of 10th inst are to hand.##The cores have nothing to do with the Commutator on the 250 light machine. As long as you have sufficient electromotive force to work the lamps and the bobbin does not over heat with 250 lamps on after running several hours then all is right so far as cores &c are concerned##All you have to do is to experiment on the best kind and form of brushes to take the current off the Commutator. I suggest that the experiment be tried with the present brushes with mercury or afterwards put on two wide brushes like those o the large machine first without mercury and then with mercury##These experiments should be hastened.
