[D8749AAR], Letter from Dyer and Seely to Thomas Alva Edison, December 5th, 1887
Editor's Notes
"You will remember that some months ago an [--]te finance was declined between you and C. E. Buell with this issue: 'The combination with a circuit and electric lamp arranged therein, of secondary batteries charged from such circuit and a polarized switch for completing the circuit though the lamps [--] secondary batteries ac[--]nding to the direction of current.' This was a claim of your case No. 449 filed June 26, 1882. We found a sketch dated May 29, 1882 which showed the issue and we drew and filed a preliminary statement (?) based on that sketch. ## Now that interference has been dissolved and a new one delcared on the same appn with a much broader issue & viz. 'The carbon (?) with a circuit and electric lamps arranged for connection therein, of secondary batteries changed from such circuit and incandescing electric lamps worked from the secondary batteries.' ## You will notice that this is ne[-] broad, on the scheme of changing batteries during the day and running incandescents off the batteries and arcs on the main circuit at night. Before Dec. 17 we have to file a new statement on this broad incentive. Buell will go back as early as June '81, if not earlier on the conception of this, so we must get as early a date as possible. The aforesaid sketch of May 29, '82 is the earliest we know of positively. Your old patent 218167 Aug 5, 79 shows two secondary batteries alternately charged and discharged. It says nothing about lamps in the charging circuit. Could you have had the idea then, and is hence any way of knowing it. ## Your English patent 4226.78 (copy inclosed) shows in figures 24 & 25 secondary batteries rapidly charged and discharged. Can you make any thing out of this? The same thing is in a caveat a little earlier. ## These are all the points we can think of to give you. We have looked through all the caveats. Can you think of anything else and what dates can you give us for the statement."
