[D8226Q], Letter from Sherburne Blake Eaton to Thomas Alva Edison, June 5th, 1882

Editor's Notes

Re Brazilian patents: "there is little prospect of either ourselves or the Brush Company getting any protection for patents." Arnoux says that Edison people in UK are having trouble with machines b/c heating; Arnoux says he has a patent to spray water on armature for cooling; offers it on liberal terms. On Friday inspected Faure batty; 40 cells, weighs 2 tons. Eaton says weight and space they take up "is appalling." Talked w/ Moses and told him couldn't give him more than 1/4. Encloses letter fr Norman Williams wrt gas engines; Eaton says "they will not work. Has the experiment of Brush and Draper, namely, using a battery to iron the waves out of the current proved satisfactory? If so perhaps we could use a gas engine." Wilson gave order for 250 light plant for St. Paul hotel; but since can't get engine for them before Aug., Eaton countermanded the order. "I fear this is an indication of the way our business will work all through next Autumn. We shall not be able to get some engines to enable us to fill our orders." Moore gg Providence to try to clear this up. Eaton fears that will be unable to get not only engines but also dynamos and motors next fall. Encloses news clippings fr London re great speculation in electric light stocks, esp. Brush. The 40 cell Faure batty now charged; 50 cells gives 100 volt at 100 amps for an hour, equivalent ot 400 lamps of 16 cp for one hour. Took our dynamo 11 hrs to charge the 40 cells. Eaton doesn't think Faure batty very practical. Read in Electrician of May 20 that Swan stated to Royal Institute of Br Architects that 200lbs coal can produce 20K candles of incandescent light for an hour. "How is it that he can stand up before the public..and make a statement like that." Amer. Steam Htg Co. "still annoy us." Told Goddard to "write them a sharp letter" and threaten injunction.
