[LM302036], Letter from Edison Manufacturing Co, Alfred Ord Tate to Philadelphia and Reading Railroad Co, Elkanah Ralph Adams, December 26th, 1889
Editor's Notes
We enclose herewith another diagram of proposed battery equipment for your lines. As none of these wires terminate in the same office, each one has to have a separate terminal battery. I have, therfore, reduced the main battery to 116 cells, and equipped each line with a sufficient number of cells to work it in case of breakage. This, of coursre, increases investment. There is also a slight increase in cost of maintenance, but it isso small as to be inappreciable.##The standard main line jar which you use is just about the same as our 150 ampere hour cell & which we would use for General batteries. In my estimate I have therefore deducted the cost of jars in anticipation of utilizing those you now have in use; we would make covers for them an furnisht he inside parts. Tehse terminal batteries working on the resistances named in your letter of 7th instant, would deliver 150 amperes in about six and a half months. The 300 ampere hour cells, on resistance named, would make full deliver in 52 days, 104 days and 208 deays, respectively, for Divisions A. B. & C. of main line battery.##In my letter to you of 13th instant, I mentioned line No. 6. Through an error the word "coils" was used instead of relays, but you doubtless understood me. I will write youi at once relative to working sounders.##We can make immediate delivery of this battery and would set it up for you free of expense. Your truly, Edsion Manufacturing Company.
