Thomas A. Edison Esq.
Dear Sir,
Learning that your prospects for a week's absence are good, I have today sent the following letter to Mr. Livor.
"H.M Livor
I beg to call your attention to the two Ore Separators in mill No. 1. The magnets upon the machines have rough faces and the general construction is such that the magnets cannot be kept in line.
This means wear upon the belt and frequent repairs to keep the magnets somewhere near their proper positions. There will be more loss in tailings from these machines than there would be from the new ones.
The difficulty of making repairs and the known dislike of your workmen to labor upon the old machines are perhaps worth some consideration
If the old machines are retained I would advise supplying them with feed apparatus and belt guide pulleys, same as those upon the machines in the refining mill.
If you do not care to have new ones built as part of the building they could be made the same as the one at the Laboratory. The floor framing could be shortened to suit the space in your building.
I do not think any changes would be required in your building; if any they would be very slight. You have height enough on each side of your dust storage.
Everything, even to framing, could be made by the Phono Wks. and fitted together in your building. This would avoid taking carpenters from your regular construction work.
Mr. Edison is at present at Schenectady with prospects, I am told, remaining a week longer. In order not to lose any time I will mail him a copy of this letter.
I leave for Ogden about Thursday. By next Monday I expect to have the 12 machines ready to turn over to the NJ & Pa Conctg Co. The last shipment will leave the Phono Wks sometime this week. — guide pulleys and coils.
Yours truly
EW Thomas
