2/9/91. H. M. Livor Esq. Genl. Mngr. NJ & Pa Conctg Co. Dear Sir I beg to call your attention to the two ore separators in mill no. 1. I did not see these until after you left or I would have spoken of them sooner. The magnets upon these [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 position. 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 these 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 Schenectady with prospects, I am told, of remaining there a week longer. In order not to loose any time I will mail Mr. Edison a copy of this letter. The Phono Wks say they have not yet received an official order for the 12 extra coils to be kept on hand for emergencies. Will you kindly send the same Yours Truly EW Thomas.
