- Editor's Notes
- "When shall you be prepared to offer for sale the primary battery which has bene developed to run the Phonograph motor? What volts and amperes can it be relied upon to give in the operation of such a motor as would be necessary to run a sewing machine, that is to say on a circuit where it is called upon for an intermittent action? What is to be the price per cell and what the expense of recharging? Do you expect to produce zinc amalgamated throughout for this battery? ### I think you will understand the intent of these queries. It appear certain that there is a great future for a primary battery which will reun a sewing machine motor economically, in cases where it is impossible to get current from a station. ### We have in this office a model of Philip Diehl's motor, adapted to a 100 volt circuit. When running at full speed with the ordinary load put upon it by a sewing machine like the Singer, it requires about 8/10 of an ampere, and to provide this amount of energy from a primary battery would seem to be a somewhat serious matter. Will your Phonograph motor operate a sewing machine to better advantage than this? ### Your kind attention to this matter will be considered a personal favor." Yours very truly, W.J. Jenks [Marginalia: "Say can't tell just yet about precis E" "Ans. 11/12/88"]
