Edison a sample gallon can.

!tr. Edison asks me to advise you about this and to Bend you the sample can by express tonight .

Hr. Whelan is going to write to you also and give you the price, so you will have the whole story tomorrow morning. You oan reach Hr. Whelan on the telephone 1064 Elizabeth, H. J.

We are on track of a muoh. larger suprly, of about sixty hundred fifty thousand gallons, whioh Hr. Edison will advise you about a little later.

Enclosed find Blueprint #3877, generalarrange- ment of Carbolic Acid Still, which is a duplicate of the one mailed you on the 31st.

Relative to Anniline Still, we regret it has been impossible to send this data to you before. It is not that the matter has been overlooked, but it has been impossible for our Mr. hunt to figure out the data until this time.

A Still of the same design as that which we are furnishing for the Carbolic Acid would not produce Anniline .

A Still of the following specifications is what you require:

To consist of one cast iron kettle, 8 » diameter x 14' long, containing 155 lineal feet 3 hydraulic iron nine fittings. Column cast iron 36" diameter with 6 nlates necessary boiling caps; copper Dephlegmator con¬ taining approximately 401 1?4" x O' copper tubes; copper Condenserof the same construction as ^

BOO callon steel receiving tanks; 1 - 5000 gallon steel receiving tank; accessories practically the same as we a?o fSshing with Carbolic Still. Pump wet vacuum, capacity 50 cubic feet per minute.

Still as per these approximate specifications, to stand 30" vacGuTwould produce approximately 3000 to 4000

gallons pure Anniline In 24 hours. Price Five Thousand Eight Hundred Dollars, ($6800.00) net, f.o.h. cars, Boston. Delivery ten weeks, possibly sooner.

We will put this in regular proposal form and send detail specifications as is customary.

We trust this will give you the information

you desire.

Dear Sir: ^ ’

X. Referring to thd proposal which has just been received from \ you for f urni thing the United States with 130,000 lbs. of commercial phenol,

I have to say that the conditions in regard to credit f curring during tho performance of the contract 8 as may able causes, are entirely satisfactory, and you are correct in your under- ^

standing that it is the regular practice of the Department to insert a *

clause in it a contracts to that effect. ^

2. The one drum of synthetic phenol recently received from yob 4 ;• ^

was not sufficient for us to make a nitration in our regular large sized '

nitrator, and was, therefore, not a fair test of the material. In order |

that I may make a more complete tost, I am sending you by today's mail, a purchase order for two (2) drums of phenol, which I would be pleased to

have you ahip^at your earliost convenience.

3. your proposal, which was the only one received, is being forwarded to the ordnance Office for consideration. As soon as instruc¬ tions are received from Washington, I will communicate with you again.

Bear Admiral Joseph^ Strauss, U. S. N. , Bureau of Ordinance,

Navy Department ,

'Washington, D. C.

My dear Admiral:- .

Vihen I was down last Friday, I.ieut. Caskey was telling me that you intend to do your own nitrating of the phenol purohased from Mr. Edison, at Indian Head.

He also thought it would he eight or nine months before you would be ’ecjiipped to sstuart your nitrating.

He mentioned this, because he thought I would like to know that it would be necessary to take oare of ordering quite a number of drums to contain the phenol until you get ready to use it on a basiB of our shipping 11,800 pounds per month.

In disousBing the matter, he wondered if it would be possible for ue to hold up shipment on this phenol, until you oould use it, along about November first or December first. I told him, & the time, I did not know, because I had not disoussed it with Mr. Edison.

I did discuss it with Urv Edison yesterday , telling him that it would be quite a labor to the Navy Department, and would also save the Navy Department the purchase of about I3g,()rum8, at ten dollars per drum.

He Btates that inasmuoh as our record business (manufacture of the disc records) bids fair to increase very much more rapidly than he had anticipated, it will become necessary for him to incroaBe the oapacity of his carbolic plant in about three months, to take oare of the increased demands for manufacture of records. He therefore fe£ls that we oan, if it will be an accomodation to you, delay beginning shipments until, say, December first, at whloh time we will start in to ship 18,000 pounds per month, approximately, for the remaining time of the contract covering a period of two years from Maroh 25th, 1916.

So if it will be any aooomodation to you, please advise me at once, and I will take the neoesuary action to carry out your wishes.

Yours sincerely.

Gentlemen:-

V/e desire to call your attention to the fact that the drums in which you are supplying us Carbolic Acid are liable to hurst when the acid is melted, especially after they have been used several times.

In our opinion,. it would he much better to ship the Carbolic Acid in tin cans of 200 or 300 lbs. each, such as the English manufacturers are using. These packages are so much more convenient for handling and there is less danger connected with their use.

Very truly yours,

Mr. W. H. Meadowcraft,

c/o laboratory, Thomas A Edison,

Orange, H.J.

Dear Mr. Meadowcraft : -

Acknowledging your letter of April 6th enclosing some notes of Mr. Edison's regarding the question of large flasks:

I have written Mr. Edison in some detail on the subject, and as I have told him, you may be sure we shall be very glad to do anything we can iJ this direction to meet the requirements.

With best regards.

WmC/DK.

receipt of letter from Mr. Headowcraft enclosing your notes on the same subject:

We cannot say positively that our low expansion glass will answer your requirements, but we have every reason for believing that this is the case. You know, of course, of the severe service which it will stand in battery jars. We also furnish tubes and large flasks to the DuPont Powder Works for service similar to what you have in mind. We furnish large quantities of tubes for what they oall a Hart Condenser, where the glass is constantly exposed to cold water on the outside and nitric acid fumes con¬ densing on the inside.

After receipt of your telegram, I found on investigation that we happened to have one flask on hand such as we have been furnishing to the Powder

f

Ur. Thomas A. Edison-2.

Works. This particular flask was rejected on account of the neck being too short and also because the annealing was somewhat imperfect. We suggested, however, that you might be able to make use of this flask for a trial, and if it stands up, certainly the regular product can be counted on to do so. Even if it Bhould happen to break, we are, nevertheless, confident that such flasks can be made without any great difficulty. The flask we are sending you has a capacity of slightly more than ten gallons. We think it entirely possible to make such flasks up to twenty gallon capacity, but if you decide to make use of any would prefer not to commence with a size larger than fifteen gallons, and ton or twelve gallons would be even better. Ab you know, of course, in such a special line of manufacture as this, it takes some time for the workmen to get their hand in.

It is even possible that a thirty gallon jar could be produced ultimately, but we should much prefer to have more experience on the smaller sizes before such an under¬ taking.

We are sending you the single flask above mentioned to-day, by express, with our compliments, and trust that it may be of some slight service in your experiments. This flask, by the way, was made in a wooden mould, and is not a fair sample of the work that can be done. In order to get proper results, iron moulds should be made. We estimate

Mr. Thomas A. Edison-5.

i ten gallon flask It is difficult to say

that the cost of such a mould for e would he approximately §110.00. what price could he made on such flasks if manufactured in quantity. We have sold small quantities of flasks of the same size as the one sent you at $7.50 each. If you will give us further particulars as to just what size and shape will best suit your requirements, we will endeavor to make you a definite estimate of costs. We should much prefer to make these flasks approximately globular rather than relatively long and flat bottomed, like a bottle.

The bottom of the flask could probably be flattened in order to permit it to rest securely, but in order to get the maximum strength, it should be approximately spherical.

A 4" opening would, we think, be sufficiently large up to a 15 gallon size.

We are thoroughly convinced from our experience in various quarters recently that our «Honex»(l« expansion) glass can be used extensively in chemical works, supplanting earthenware, enameled ware, and even in some case quartz.

V/ith assurances that we shall be glad to render any assistance possible, we remain.

Very truly yours,

\Corning Gl^B/J&rks./

Chemist is of the opinion that this may he due to imparities in the form of Ortho-lTitraniline , or Meta-Hitraniline , or both. !7e trust that this slight difficulty can he overcome and that Mr. Edison will he pre¬ pared to state before long in what quantities he will he prepared to make the material upon the completion of the new aniline plant— which 1 understand is expected to he ready in about two weeks time.

It may he, and probably is, too soon to inquire as to the probable cost to us of the Paranitraniline; but this naturally is a question in which we are interested and upon which we will be glad to have your decision at your early convenience.

At the same time we call your attention to the fact that the Paranitraniline is useless without Beta Haphtol so that we are equally interested in knowing what success you are having in pro¬
