[LB007918], Letter from Thomas Alva Edison to Charles Lorenzo Clarke, August 15th, 1882
Editor's Notes
On the railway we find when starting [that on] armature takes all the Current away from the field, without [we] connect it up so that it takes an enormous power to work field. I have had the field magnets taken out & sent to [gouc--] [--] please calculate wire for field so we can [--] [--] [-----] cost the armature. I learn from reading that nearly all Dynamos [[[[] [--] [--] in field [saw] bobbin but as our field is more economical I think the [re--tion] of field should equal the armature [art] if you think this a good guess please calculate what size of wire should go on or whether it couldnt be done with greater convenience by [sw--al] no 10 series
