Pear Sir:-

You will not remember me, as you never saw me Tout once, and that was at a reception to you in Port Huron when 1 was a youth, hut you will know who I am when I tell you that I am the eldest son of John Edgar Miller, of Port Huron.

I do not, however, wish to trespass upon the old boyhood friendship between you and my father, except in so far as to call your attention to the enclosed article from the Los Angeles Times of Feb. 15th.

I am an enthusiastic user of automobiles, and heretofore used the gas explosion and White steam types. I would very much like to know how authentic the enclosed article is, and whe re and how soon a machine with one of your new batteries could be secured.

I enclose a circular, fac-simile of which was issued by Messrs. JJ. W. Harris & Co., Perry, Coffin & Burr and E. H. Rollins Sc Sons, which will show you my field of activity. It seems quite a coincidence that I should be at the head of an "Edison Electric Company."

I trust that it will not too greatly inconvenience you to devote a f ew moments with your stenographer to the inquiries I have

Thomas A. Edison,

Dear Sirs

Mr. A. Churchward of the General Electric Company, whom I have just only "been able to see, advises that the two motor ar¬ rangement, to his mind, would not he practical. He thinks the two motors will he much more expensive, and on account of their small size inefficient; he also thinks that he has no motor small enough. He will let me have a blueprint of a motor such as he ad¬ vises to use and upon reoeipt of the latter I will make another de¬ sign. In this I would again use a compensating gear unless ad¬ vised by you that you wish to abide by the two motor arrangement in spite of what I have written above.

Yours respectfully.

New York, February 27th 1903

Thomas A.Edison, Esq.,

Fort Meyers, Fla.

My dear Mr .Edison,

I have received the test cells and have just gotten ray testing board finished, but have not received the instruments yet. Expect them in a day or two when I shall start in a series of tests.

In regard to running one of the D.L.& W.cars with your batteries, would say that taking the distance between New York and

Morristown at 25 miles and 12 stopB per mile, with a maximum

. -

acceleration of 6/10 of a mile per hour^which iB standard steam car practice, the cars making 35 miles an hour maximum would be able to make a schedule speed of 25 miles an hour. 40 seoonds at starting the car would take 160 K.W. and 60 K.W.when running at full speed on the level. The average energy for one hour would be 70 K.W. Taking the car with extra motors and controllers, it would weigh 30 tons without batteries. By putting on 5 tons of batteries, it were possible to make about 100 miles, and as under the very best conditions and proper starting it would take 70 K.W., it would seem necessary to put on a great deal more battery and, of course, the energy necessarily would go up in proportion.

I saw Mr.Htrschman of the Adams Express Co., and he tells me that you have decided not to use a single motor and differential gear on the small 3000 lb. delivery v/agon. If you use two motors the

T.A.E.-2-

efficienoy would be low and the weight much higher per horue power than with single motor and differential. There are a lot of differentiala on the market which are very simple and which are not liable to get out of order. Where the power and wagon are I think it advisable to use a single motor and differential.

Have you started anything on the drawings for the run¬ abouts yet? I have your book and am writing it up now, and will send it to you the latter end of next week.

I have a letter from Mr. George Hays that the batteries for Mr .D 1x4.8 oarrigge would not be ready for at least four or five weeks. If satisfactory to you, I will rush a motor through at lynn so that the rig can go over complete with one of our latest motors. Kindly let me know as soon as possible in regard to this so that I can start ahead with the motor.

Yours very truly, *

Mechanical Engineer,

v-vW'U-

New York, April 1,1903

Mr. J. M. Lansden, Jr.,

Bimmingham Eleotric & Mfg.Co.,

Birmingham, Ala.

My dear Mr. Lansden,

Mr .Hill has sent me copy of your letter in regard to the automobiles 34 and 35. 1 note what you say in regard to

dropping the voltage on these motors, hut from a good deal of experience in these low voltage motors in the last year, would say that 1 do not think it advisable to build a motor below 47 volts.

It is perfeotly feasible, ofcourse, to build, them for lower voltage, but the commutator loss goes up very rapidly, and l think it advisable to put in the extra oellB and get a better motor.

Eor mstanoe, the motor used on the Baker wagon is 20 volts, and stands still on 6.2 volts. This is what 1 consider a very great loss. Again, the controller becomes difficult to keep from burn¬ ing due to large currents, and from a number of experiments which we have lately made a very slight bum ..will have a higher re¬ sistance than the rest of the circuit, so everything points to keep¬ ing the voltage aB high as possible.

In regard to winding of the motor, would say that it will be a series wound motor with two sets of field coils which will be at full speed and the last notch in multiple. In starting and the intermediate points up to the last but one, the fields will be in series, which will give the greatest possible torque with the leaBt amount of current and will give, therefore, really two running points, the last and last but one, which will correspond with your data with a rig weighing 240o lbs. of 14.6 miles an hour and about

J.M.L.-2-

10 miles an hour, without the use of any resistance. I find this series parallel arrangement of the field very useful in starting, as it ,d|dts down the excessive current and at the same time gives a maximum torque with minimum ourrent for had roads and for man¬ euvering. The controller will have shout six or seven points forward; the first point being the high resistance which, on throw¬ ing the reversing switch, will act as an eleotric brake for long coasts down hill. This 1 find relieves the mechanical brakes very rauoh. The next four points will be simply resistance points and used for starting cad maneuvering and are not running pointB,and the last two points with the fields in series and multiple, respeotively, are really the only two running points.

1 suppose you propose to use 2V2 or 3 inch Bolid tires, as your energy consumption seems to correspond to that. Where are you going to place the motor, and what kind of differential are you going to use? Also the type of chain? I should like to have you write me and let me have all the points which you can, and if you will write out any questions which you want me to answer or any data you want, 1 should be only too glad to Bend it to you at the very earliest moment.

1 received a telegram from our feotory at Lynn saying that the Mark 37 motor would be approximately 1SX/Z inches in diameter,

17 inches over the frame, and 20 inches to the end of shaft.

Yours very tiuly,

Mr. John M.Lansden,

Manager, Birmingham Electric JJ^g.Co.,

Birmingham, Ala.

My dear Ifr.Lansden,

Youre of the 3rd instant received. 1 think it would he better a till if you can get 40 cells in, as you suggest in your letter, as this will, of course, drop the current correspond¬ ingly and help out all around. 1 can hardly agree with you in number of points on the controller, as from experience with several hundred vehicles, 1 find that the controller as made to-day, has too few points, and find it is easier on the motor and gearing having more points, so that there is a longer time to get »t 0MW.

In regard to resistance points.theso are separate from the controller, and can be ordinary enamel rheostats or something similar geared to the c ont roll er, which only has a very few points. 1 rather in favor of having the reverse separate from the con¬ troller, as past experience has proved that giveB the best satis¬ faction. The Electric Vehicle Comoany of Hartford started in to make their controllers with rerers separate, changed to having reverse on the controller and have now changed back to the separate reverse again.

What type of check are you going to use on the steering mechanism? 1 am taking this up now on a gasoline electric touring oar, and have got hold of a very good thing. Perhaps we can swop

2

ideas on this matter.

I notice .lia c you say about the generator brake . Do you intend to use the electric brake by short-circuiting the motors themselves or by reversing the motors through a high resistance? If you will let me know which you intend to do,l will discuss the matter further with you. 1 wn looking forward to the blue prints.

X enclose you an outline blue print of the proposed motor. I notice that you do not intont having a removable plug or switch for open¬ ing the circuit when the machine is left. What, prevents this from being started by some person when the rig is left? 1’here have been one or two accidents in Yew York due to this point.

1 urn doing everything 1 esn to push th^se matters.

I note in the last p&ragr^i of your letter that 'the motor is new to you. It is practically the zoate motor 1 have been build¬ ing for the lust five years, but lately 1 have proved that it is superior to a'l other types of motors.

I hajify your esteemed favor of the 29th. ult.; permit me to thank you fpr the information contained therein, which I receive and consider in the strictest confidence.

I am much surprised and disappointed at such news, which accounts for a certain vagueness and irregularity in Mr. Hill’s recent corres¬ pondence and various propositions. I could not understand why Hill, in his apparent position, should have difficulty in raising the neces¬ sary money for the construction and development of these first two . cars, from all that he said to me, since I of course had no reason to doubt his sincerity, in the least. Further, I entered into this work, in February, if you remember, on my own responsibility, in¬ tending to construct the two machines on lines that would meet with your entire approval, demonstrating the practicability of my ef¬ forts on these machines, in conjunction with your battery. Since then, Mr. Hill desired the work to be done on the responsibility of the proposed company, which he would organize, to build such cars.

Therefore I felt it only right that the proposed company look out for the financial end, which would be done, as we were so assured^repeatedly by Mr. Hill. I have devoted most of my time since the first of the year to this wprk, and neglected in a way the usual business of my company, in view of the possible future, and my desire to emgage actively in the electrical automobile field.

ana interest in this work, I do not care to associate myself or in¬ terests in any way, that would not meet your approval, from either a mechanioal or business standpoint.

I have made no contract with Hill, and would ask you to advise me just what to do in this matter. Would any association , of the right kind, with Mr. Hill make a difference in your interest or inclinations towards our work or results, or association?

I have both machines well under way, and propose to complete them, send them up to you, whether hearing financially or not from Hill, providing my designs and intentions are satisfactory to you.

When may I get the batteries for the two machines? I believe that these two cars, when fully developed, will meet the usual requirements in a commercial field, without difficulty, barring the

rubber tire question.

My ultimate object has been for the past few years, to turn out a common sense machine in every respect, andwith your valued opinions and suggestions, and interest in my efforts, I am anxiously await¬ ing the results of any test or trial you may give them, when com¬ pleted.

Thanking youn again, I am

Yours truly

I write tol inf orm^you thM; we have not yet been, able to hear from Mr.Chi|roliwpd, re^dkng the t^o ~mo t^r^for ofrr vehT^ icles. I cannot understand why we have ha^^o^^ply ^o^our lettegp.

All our calculations hwt ^een''&E^eTpi?"his motors. We’*have~now reach¬ ed the stage in our wKktwhere we nee^thfcm and thought perhaps you might be able to find out\ whether or not jre can^ST; these motors from Mr. Churchward in any reasonable time. We- have not taken the matter of motors up with the Westinghouse people, having counted on Mr. Church¬ ward. I write the Westinghouse Company to-day, to avoid any furthmr

Our machines are well under way and we will be ready for the batter¬ ies in about two or three. w^eks.

We have on hand two Elwell-Parker motors, approximately the same type as the proposed Cyperal Electric i with such windings, as to make them fit for our temporary service, if there is any delay on the other motor.

Referring to the storage battery blue print, 76B. , the best arrange¬ ment will require, for/ each machine, eight trays of five cells each.

We have. managed to get hold of very good materials, all the way through and have made several pronounced improvements^ occassioned by the practical construction. The' weights are well within the limits.

I have had on hand, for some time, a runabout, which I have been anxious to equip with a battery and get some service out of it or dis¬ pose of it. Are you in shape, at the present time to furnish us
