[D8135ZBB], Letter from Charles Batchelor to Thomas Alva Edison, August 30th, 1881

Editor's Notes

Half light machine stripped off brass wires and came off the canvas, bending the bars considerably. So ran lights with the full light machine. Fixed the armature the next day. "It was a great disappointment to some of our competitors to see us come up to the scratch 3 hours before time & run all night." Says the armatures run too close to the field coils and to give an extra 0.010" clearance. Both the armatures touch the field coils when running at full power. Swan is lighting the room next to theirs; his lamps "are very irregular and ever since we have been here he has been weeding them out. Whereas with our lights no difference in intensity. Says Swan and Maxim only have "a lamp or a machine, and even their lamp does not begin to compare with ours." TAE has a system and better individual components. Had a visit from King Kalakaua of Hawaii. Hired a French and German translator to explain exhibits to visitors. Gambetta also visited; thinks he also holds large interest in gas shares. "Bailey has applications from Brussels, Vienna, Lyons etc and if we do not supply them of course Swan and Maxim will." Has heard that Brush sold his light to Credit Lyonnaise for 2M francs. Syndicate has appointed 3 engrs to examine TAE light; 1 will be Armengaud. Doesn't doubt that they will be pleased with system. Paris gas company has a monopoly for underground mains lasting another 20 yrs, but city can break if if a better method of lighting comes along. Paris is a promising market b/c residences prefer candles to gas b/c cost of gas. Also wants TAE's views on isolated plants. poss select: good coverage of exhibition, competition w/ Maxim and Swan, and potential Paris market. dh 2oct02
