[LB018157], Letter from Thomas Alva Edison to Edison Electric Illuminating Co (Brockton), William Lloyd Garrison, Jr., July 24th, 1884

Editor's Notes

Your favor of the 22nd. inst. came duly to hand.##With relation to the question you raise as to whether we have Messrs. Babcock & Wilcox boilers at our central station which are nominally rated at 1000 horse power, but which the Babcock & Wilcox people assure us can be depended on for [1600] horse power in Winter, if we will use a blower. We have subsequently added lamps on to the system, which will compel us to take 1500 horse power out of the boilers this Winter. In [Chibbock}, to satisfy himself in relation to this matter, run the station one day with two boilers only, and found the statement made by Messrs Babcock & Wilcox perfectly correct.##With the blower we sent you, but which you re[----] could get the power out of your boilers, which you will [run] the Winter. Of course in the course of time you will get the whole 3200 lights on to your station, and I therefore think would be well to put in another 75 horse power boiler.##With relation to the feeders, the determination the Light Co. had an error that the mains that should have [---] for 1600 lights under the contract, have a capacity of 3200 lights, [while] [your] feeders are only made for about 1200 lights. It is [----- ---] pressure consequent upon this that [we] think that the dynamos are overworked. I have had my man make estimates for the feeder and some extensions in the mains for 3200 lights, and he figures that it will cost from $3,000. to 39,000.. This is somewhat less than the original estimate for 3200 lights. Inasmuch, however, as you will not have any less than 2000 lights on this feeder, you can doubtless strengthen up this feeder at a cost of from $3,000. to $4,000. Mr. Kruesi will send a man on to measure the loss of pressure to-night, in all probability, and this he can figure very closely for you in case of any extension or alternation, but you must be carful to give his man the position on the mains of any large customers, who are not on when he measures, but who will be in the Winter, and also tell him what number of lights they will probably burn.
