Title

[LB011326], Letter from Thomas Alva Edison to Nathaniel Shepard Keith, February 20th, 1882

Editor's Notes

Referring to your favor of 15th I will get out the data for the new Book & send it to you as soon as possible.##Weston claims to have designed a machine for Professor Silliman] in the latter part of 1879 wherin he used copper bars across the surface of the Cylinder connected together by Copper discs the same as in my machne and he shows four or five drawings of a machine which looks exactly like his No 4 Light machine, but these drawings do not contain any bars or discs but he testifies that they were [intended] to be used on the machine of which he puts in the above [offered to] drawings. Althugh I have not seen the Testimony I believe Prof Silliman has testified to the fact that he Weston had explained to him that he was going to use bars and discs.##What I should like to have you find out from Prof Silliman is whether he really understands exactly what Weston did explain to him and if he (-] understands the principles governing the construction of a Bar & Disc Dynamo. My impression is that he does not and that he testified under a misapprehension as all our investigations seem to prove that Weston never had such an idea.##I spoke to major EAton about making arrangements as to combining on the regulation of the field of of force magnets against Brush but he does not seem to have attended to the matter. Will you please speak to Gordon about it and I will go and see him myself
