My dear Mr. Schmid:

You have, no doubt, learned through the papers of the unfortunate accident which has deprived me of all my apparatus, and of some results of my recent work. I must now rebuild my laboratory, and will require some machinery. I shall write a letter to the Westinghouse Company about this after consulting Mr. Adams. You will greatly oblige me if you will do what is in your power to ship what is required with the least possible delay.

Thanking you in advance. I am

Sincerely yours,

Mr. Albert Schmid,
Pittsburgh, Pa.

My dear Mr. Schmid:

You will remember that some time ago I wrote to you that I was going to want some of your best annealed converter iron strips. I have now decided as so --- size. They are to be two and five-eights (2 5/8) inches wide and eleven and five-eights (11 5/8) inches long. As to thickness, --- use --- the same as on your converters found most practical considering performance and cost, etc.

I assume that these strips will be readily obtained without much delay, and as they will be punched they will be of uniform size.

You will add to my many obligations if you will kindly see that these strips are of the best quality of iron (or steel) and annealed most carefully, as shipped with the least possible delay to my address above. I want enough of these strips to make up a weight of one thousand (1000) pounds.

Kindly let me know upon receipt of this letter when I may expect these strips. As the time is pressing, I would beg you to forward them by express at my expense.

Hoping that you will oblige me by attending to this matter at once, I am sincerely yours,

Mr. Albert Schmid,
Pittsburgh, Pa.

My dear Mr. Schmid:

Oblige me and let me know, immediately upon receipt of this, what is the smallest size rotating 2-phase transformer you have in stock. I would like to have about 25 cycles a second, as adopted in Niagara. The commutator should be one possessing a great number of bars, so that I can get a continuous current which I want for some purposes in the laboratory. I would prefer such a machine to one which has got only few commutator segments, and in which the current is necessarily undulating.

I propose to use a machine of the above description and capacity about 25 H.P. or so, for driving motors, and what little machinery I want in the electrical department of my shop. I have provided steam-power for my work-shop.

You will add to my obligations if you will let me know what motors I could get to go with that machine.

The tension should be from 125 volt upward to no more than 220 volt. I may use a machine of say 110 volt if one should be in stock. Furthermore I am not limited exactly as to the capacity, and it might be something more than 25 H.P., but not very much more.

Hoping to receive from you an early and favorable reply, and thanking you in advance, I am

Sincerely yours,

New York City, April 3rd, 1895.



Mr. Albert Schmid,
Pittsburgh, Pa.

My dear Mr. Schmid:

Many thanks for your kind letter. I have made up my mind to purchase a machine of the kind you refer to. I have written a letter to Mr. Bannister, and would beg you please confer with him without delay. I can assure you that I shall be grateful for your help. The machine should be wound for 220 volts and should give 3200 alternations per minute, and I shall buy later on motors also wound for 220 volts. About those motors I shall write later on, as I infer that there would be not much delay in getting them. The capacity of the machine should be about 30 H.P., but may be 25 if you like, and it is very important for me to get it as soon as possible, as much of my work is being delayed. As I intend to use this machine for certain specific purposes in connection with the oscillators, a high efficiency figure is an important item. Please therefore, do not spare any pains or expense to secure the best result. I shall rely, as to the price entirely on the fairness of the Westinghouse Company, I believe that there are gentlemen in that company who believe in a hereafter.

You mention in your letter that it would want six weeks to furnish the machine. Should you find any way of shortening this by selection of patterns existing I would be much obliged to you for doing it. But I would want, as I stated before, the best workmanship, and the best results which are within the reach of your ability and experience.

Kindly advise me whether this is understood, and whether you are going on with the work.

Very kind regards, I am

Sincerely yours,

Dear Mr. Tesla:

I am in receipt to-day of your letter of the 3rd inst. And have instructed Pittsburgh to prepare and ship the rotating two-phase transformer described by Mr. Schmid. The order will receive our best attention, and when I get the data it will give me pleasure to make the price as low as we possibly can.

I have regretted every time I have thought of your misfortune that you should have met with such a loss. I am very glad to know that you took off your coat and went to work again to get everything back into shape as soon as possible.

I expect to be in New York several days and shall hope to have the pleasure of seeing you.

Yours truly,

My dear Mr. Schmid:

Your dispatch, advising me of the shipment of the balance of the strips, received. I have also received a letter from Mr. Bannister, in which he informs me that the order for the rotary transformer is put through the shop. You will greatly oblige me if you will push the work on that transformer, and make it excellent in every way, as it is likely that I shall exhibit it in connection with my oscillators.

Mr Stillwell told me the other day that you have shipped to my address the two rotating-field rings which were exhibited at the World's Fair. I am very anxious to get them, but as I have, as yet, not received anything, I am afraid that they are somewhere at the railroad station. Kindly look into the matter and trace them.

46 E. Houston St.,
New York City, April 23th 1895.

Mr. Albert Schmid,
Pittsburg, Pa.

My dear Mr. Schmid:

Some time ago you will remember I wrote you about some high-tension converters which I needed in the pursuance of my investigations, since the old ones have been destroyed.

Upon receiving the high-tension converters from the World's Fair, I found that one of them was injured. I was then obliged to take it out and repair it, and on that occasion I noted certain defects which I have tried to remedy in the design which I have mailed to you this day.

I have no doubt that the drawing will be clear enough for you to save all description. I would only remark that in the making up in the secondary spools I have assumed that you will use fiber washers riveted together by small brass rivets. These washers I supposed you can make up of small pieces, so that they would not involve the gutting up of large fiber sheets, but i do not want you to spare a few dollars on my account. In the center of the iron core I have found it indispensable to put a brass bolt as indicated in the drawing, and furthermore to place iron strips in front of the ends of the core. These strips I need for several reasons.

I would beg you to instruct Mr. Kaiser to wind these secondaries most carefully and try to place exactly 100 turns of wire #26 on each layer. On the ends of each layer wind string of slightly larger diameter than the insulated wire, so that there will be a tendency for the paper that is placed between layers to bulge up on the ends. This paper I calculated to be very nearly 1/64 inch thick.

The ends of the secondary ought to finish as indicated in a and b. Of course I count that you will put fewer turns on the last layer, and then wind thick and stranded wire on top to protect the finer wire.

Each half of the primary will have four ends, as the winding is made by two wires insulated from each other. There should be, then. Eight binding-posts for the primary.

Please oblige me by a reply whether everything is understood, and begin the work without delay.

I shall be very much obliged for your personal attention, and for any services that you may render me in this connection.

Very truly yours,

Mr. Albert Schmid,
Pittsburg, Pa.

My dear Mr. Schmid:

In writing you yesterday about the high-tension converter, I forgot to mention that I would prefer to place the iron tank, which should be very strong, on a small truck fitted for that purpose, so that it can be readily moved.

You need not cover the iron tank with the boards, as you did on the old apparatus, as this simply increases the weight and cost.

Inside I have shown the wood, which, of course, should be the dryest pattern wood, filling as much space around the coil as possible, so as to reduce the amount of oil to the minimum. Besides saving the oil there is an advantage of the coil being lighter and safer. Please therefore, instruct the carpenter to cut off the pieces so as to fit everywhere around the coils to a distance of about 3/4 of an inch from each.

Please remember, also, that when winding the secondary I would under no circumstances use shellac or any other varnish, but some light oil, as paraffine oil, which will be brushed over each layer when it is finished. Do not use liniseed oil, as the coil might get hot during the winding.

You will greatly oblige me if you will send me a dispatch upon receipt of this, that you have my sketch, and that you are proceeding with the work.

Hoping to hear from you shortly, also, in regard to the rotating transformer which I have ordered, favorable news, I am

Sincerely yours,

My dear Mr. Scott:

I have written to the Westinghouse Company about a high-tension converter of a somewhat modified design which I intend to replace the old converters constructed for the World's Fair.

Although I know that Mr. Schmid will do for me as much as he can, yeat fearing that he may be too busy, or away from the factory, I write this to ask you if you would not kindly devote a little attention to this small matter. I shall be very much obliged to you if you will see that I get at least one of the two converters very soon. I hope also that you may be able to advance the construction of the rotating transformer which I have ordered some time ago. My work has been suddenly interrupted just as I was at the most interesting stage of the development of certain ideas, and I need very much my apparatus to begin work anew.

Mr. C. F. Scott, Electrician,
Westinghouse Electric Co.,

Dear Sir:

Your favor of May 11th just received. I know that you have an extended experience in kindred matters, and that you will employ the best method of bringing out the terminals. I would only suggest, because of the convenience I would have, that you put on the top substantial binding-posts for the primary as well as for the secondary wire, so as to enable me to attach to the latter a heavy wire. The rubber columns, on top of which the secondary binding-posts are to be placed, should be removable, so that they would not interfere with the boxing in case of shipment. The best way, it seems to me, would be to connect the secondary wire as deep in the tank as possible to two metal blocks, in to which metal rods covered with hard rubber would be screwed.

I have further to suggest that the tank be placed on a small truck with rollers, and there should be on each side ordinary iron handles for eventually lifting the whole.

Hoping that I shall get the coil soon, and thanking you for your attention and trouble taken in the matter, I am

My dear Mr. Schmid:

Your dispatch in regard to the converters has been handed to me this moment, and I have replied immediately by wire, asking you to ship the converters by express, in view of the long delay by freight. I am very disappointed for not having, as yet, obtained news of the rotating transfer, although it is now over ten days since, according to your letter, it was shipped.

With best thanks for your kindness, and anticipating the pleasure of seeing you soon, I am

Very sincerely yours,

My dear Mr. Schmid:

The rotating transformer has been finally received, and I am very pleased by the first inspection of the machine, which shows that you have bestowed upon it more than the usual care.

I shall be much obliged to you if you will kindly send me blue-prints of the machine and such particulars as you can give without departing from the usual practice of your company in kindred matters. I would like, of course, to know everything pertaining to the winding and constants of the iron, so as to be able to profit by the experiments with this machine as much as possible.

Hoping that the high tension apparatus will be received in good shape, I am

Yours very sincerely,

My dear Mr. Schmid:

I have run the motor yesterday, and was very much pleased to note the great improvements you have made in these machines over those of two or three years ago. I have no doubt that it is a highly efficient machine, judging from the quickness with which the speed regulation is effected. My idea was that you would ship a pulley together with the motor, as you do with generators. The most suitable size for me would be between 16 and 20 inches. I would like you would send on one which is very well balanced, of that size, or slightly larger.

Hoping to hear from you with return mail, I am

Sincerely yours,

My dear Mr. Schmid:

Will you kindly forward, as speedily as possible, rings of sheet iron, 9-1/2 inches inside and 11 inches outside diameter? The thickness of the sheet iron should be between 1/64 and 1/32 of an inch, or whatever thickness you use in your armatures. The iron should be of the highest quality and best annealed, and I shall want about 100 pounds of these plates.

Hoping that you will be good enough to personally order this material, I am

Mr. Albert Schmid, Gen.Supt.,
Westinghouse Electric Co.,
Pittsburgh, Pa.

My dear Mr. Schmid:

In examining the high tension converters which I have received yesterday, I find that a few mistakes have been made, which I will point out for no other reason beyond the desire to be useful to you.

I find that instead of the laminated iron as required in my first communication to you, there have been put flat bars of ordinary iron on the ends of the core. Furthermore there were no holes on the bottom nor on the sides provided for the oil to circulate. The middle connection of the secondary coils should have been insulated by a rubber bushing or otherwise to prevent a break through, when by unevenly loading the terminals the coil becomes unbalanced. Another defect was that the coil was placed too low, but this I have easily remedied by placing a few boards underneath. Another oversight was made in tacking the ends of the high tension wire to the frame-work, because you know that no matter how dry the wood is, it will conduct such a current of high tension and short-circuit the coil. The screws which fastened the ends of the secondaries to the terminal wires passing through the rubber columns should have been placed sideways, as they can easily fall out and disconnect, the way they are made. The primary wire should have been sunk into the wood, as required in my sketch, this being necessary so as to enable the inserting of the laminated iron plates opposite to the ends of the core.

Otherwise the coil seems to be made up excellently, and the parts well fastened in the frame. I consider the arrangement of the central wood plate with the blocks on the sides to keep the secondary coils in position, a very good one.

You will oblige me in forwarding the exact particulars which relate to these coils, and I shall let you know immediately after testing them, how far they meet the requirements.

Hoping that you will not take these remarks as an adverse criticism, and thanking you again for your kindness, I am

Sincerely yours,

Mr. Albert Schmid, Gen.Supt.,
Westinghouse Electric Co.,

My dear Mr. Schmid:

Your letter of June 28th has been received, and I thank you for the information contain therein.

In examining further the coils, I found that a more serious defect was present, which, however, it was easy to remedy. If I mention this you will, of course, know that it is done with the most friendly motives.

I found that on the secondary ends which were connected in the middle above the primary, there were brass plates fastened one inch and a half long and about 1/4 inch wide. These brass plates should have been placed tangentially to the coil. Instead of this they were placed radially and over 1/4 inch beyond the first secondary layer. As the whole secondary wire takes up 5 inches the brass pieces were thus made to span from 60 to 70 layers, and this defect was still further increased by the screws protruding a good depth into the fiber. In case of a superimposed vibration in the secondary, there might be easily 100,000 volts between the layers spanned by the brass plate, and the coil would surely break down. The fact is that the old coils broke down in this way, and I was particularly thinking of informing you in this regard, but forgot to mention it when I ordered the present coils.

I have placed the laminated iron, and have soldered the ends of the secondary in the middle, doing away with the the two brass plates, because they were unnecessary and could only cause trouble.

I was pleased, in examining the coils, that the wood frame was excellently made up, and everything seemed otherwise in perfect shape, and it was quite evident to me that you had taken great care in constructing these coils.

With many thanks, I am

Yours sincerely,

My dear Mr. Schmid:

You will perhaps remember that last Fall I took the liberty of recommending to you, through a letter, Mr Emile Smith. He is a graduate from college, and has had some practical experience in mechanical and electrical engineering. You know that I do not often recommend people, but the good opinion that I have of Mr. Smith prompts me to once more write and ask you whether you might not be able to give him a position at present in some of your factories. If you can do so you will oblige me.

Sincerely yours,

Mr. Albert Schmid, Gen.Supt.,

My dear Mr. Schmid:

I have just received the blue-prints pertaining to the 30 H.P. rotating transformer, and wish to thank you for them. The German silver wire resistance box for starting the transformer has not yet been received, but I presume that it is shipped or if not, that it will be shortly forwarded. I have received the box for the field regulation.

In some of my tests I would like to run the transformer up to about 1200 revolutions per minute; this would be 50% higher than the normal speed. I am convinced that there would be no danger whatever, judging from the general aspect of the machine, but I would beg you to let me know whether you consider such running safe.

Anticipating an early reply, I am

Mr. Albert Schmid, Gen.Supt.,
Westinghouse Electric Co.,

My dear Mr. Schmid:

Your favor of July 10th received, from which I learn with pleasure that the starting-box will be shipped this day.

In my letter to you yesterday, I asked you to forward six dozen of your binding-posts, and would here repeat that you will oblige me by sending them on without delay.

In addition to these binding-posts I would like to get some of your single and double switches, because I can get them cheaper from you than from the supply house here. Kindly forward half a dozen double switches and half a dozen single. The latter ones should be, roughly, for about 50 amperes, and the former for about 100 amperes in each circuit.

For some contrivances which I am driving with the alternating current I require a couple of small alternating motors. The best size for me would be about 1/4 of a H.P. two-phase, and about 1/8 of a H.P. single-phase induction motor, if you have such one on hand. The E.M.F. is immaterial; I presume that you wind them for 100 or 50 Volts.

Should these sizes not be on hand, please let me have the nearest to it.

Hoping you will have the kindness to attend to this matter, I am

Yours sincerely,

I thought that you had a large number of these binding-posts in stock, as you are constantly using them, and I would wish the large size. Anything that you select will be suitable for me. I would make them up in my shop, but I cannot spare the time, as I must keep my men on more important work.

Hoping that you will be able to find something which will do for my purpose, and thanking you, I am

Dear Sir:

Last July there was a young man by the name of Emile Smith who came to us with letters of recommendation from you. He has yet to work in the factory and about the middle of last month was taken ill with typhoid fever. He went to the Metropolitan Hospital in this city but did not get any better. Last Saturday they telegraphed for his relatives. His sister and a lady friend came on, arriving Monday, and stayed with him until he died yesterday ( Thursday afternoon at 2 P.M.). I took charge of matters and see to the embalming of his body be forwarding same on 6 o'clock train last night to Detroit. The remains were accompanied by Miss Smith and Mrs. Leitner.

As he was a personal friend of yours I thought perhaps you be interested in learning of his death.

Yours very truly,
