Find Louis Glass and have him see Major Hat on, who Tri.ll give information about Choever and Gilliland.

Get a list of all Phonograph Companies and write them that in the course of a month I shall be able to furnish nickel in siot attachment at factory prices, and they need not pay large price to out¬ side parties, if they desire such a device. See Lippincott about this before you do so. This to head off the Che over -Gilliland deal. Perhaps Lippin¬ cott has the right to prevent Cheever.

Did I tell you that Edison says he does not want his name used in Cheever's Company? lie wants Gilliland's name*' caken out altogether, but does not consent to have his own’ ased and prefers that it should not be. .

In regard to the manufacture of Nickel Slot, attachments for use in connection with the phonograph, the agree¬ ment between the Automatic Phonograph Exhibition Company and the Edison Phonograph Works , of the 19th of April, 1890, 5th section, requires the Works to prepare a model at the expanse of the Auto¬ matic Company, according to the best judgment and skill of Thomas A. Edison, together with a duplicate of the said modal.

The proper way for us to start under this agreement is to •; carry out the obligation thus imposed and get a speedy decision on a permanent model. We have no right to wait for the Automatic Company to supply a model, and they liave absolutely no right to, ask us to do so. It seems to me that Gilliland is taking advan¬ tage of this delay to manufacture as mary machines as he possibly can. He has already made at least 300 in excess of the 500 which we agreed he should make, and I believe ha is still delivering.

i also enolose you a statement of the batteries owned jointly by the Automatic Company and Old Dominion Company, 189 storage batteries costing #2043. You will understand that our Company own one half of these batteries, and that Mr. Edison is interested to the extent of one quarter of what we own.

I also enclose you a letter dated Oct. 8th, in reference to nmsioal cylinders, and a circular sent by the Hartford Model 0o» to the various looal Phonograph Companies offering to furnish Automatic Slot machines. After a careful perusal of these papers would you kindly hand them to Mr. Edison and call his attention to these matters. As he is the largest personal stockholder, Z think it is no more than right, that Mr. Edison should assist US to the fullest extent possible in asserting our rights in these various matt era and bring them to a head as quickly as possiMs*

Alloir ms to suggest to you that an automatic register, or bell attached to a set of your batteries by which the user could be informed when about the battery is giving out,, say within five ' hours, would greatly enhanse the value of your battery, I should think Mr. Bdison would have no difficulty in invent i** a devioe of this kind for you.

•Gentlemen:- * & £ ■'* £ V

Wo desire to call your.rattentfon to the “Hartford i Model." nick el-in-the-slot attachment, manufactured"- by ‘this' Com¬ pany for iis e with the phonograph v jjf / f'. ~ e

This attachment is simple in cons ^Sniot'l on“ purely, automatic in action, is compact, neat,; and reliable, lit requires' no pre—

paratory change or alteration in the phonograph arid can be attach¬ ed or removed in the space .qf a few? minutes and with but little trouble . It is entirely mechanical’ in its! act ion fusing no oleotro-magnots or- delicate,, adjustments, wj-ill /serve tpr any , length of cylinder, is nicely nickel plate’d arid makes'^ beauti¬ ful and attractive addition to the Phonograph., All that as nec¬ essary to operate the mechanism islithe dropping of a nickel in the tube- the attachment 'and phonograph do the rest . ;?The£ act •) on of t.ho attachment is also plainly seen, which ^contfi but esc' mater¬ ially to the interest and consequent profits of the automatic phonograph. The nickel arrangement is unusually prompt, reliable and satisfactory and the combination makes the simplest and best ,■ attachment of the kind now on the market .

We are prepared to make contracts i^ith your company for the uf? of .Model" on the most advantageous terms. 'W@‘ will rent or- sell you -the machines, or, if you prefer, will take charge of the. business in your territory, leasing phonographs from your company on such terms1 as may be agreed upon. Wo require no exclusive contraot and make no extortionate demands and we be- •7? 1'® oonpfmy can derive a great, er profit from, this phase wavth0' bll°in0SS by th° US® °f °lU> Rttacl™ents than ' in ' any- other

idle profitable nature of the business is probably already known to you and wo should be pleased to assist you in its de- I?/0™' torritory- If!?™ have as yet, made no con- 1™°** °f this nature 'we will submit for your consideration our methods of work. i.

Omaha, Nob. Oct. J34, 1800.

I herewith enclose you photographs of a multiple-tube attachment for the nickel-in-th e-slot . The photographs show two tubes. Three, four or more may be used, but probably two tubes in addition to the one already used would be ampler Photograph No. 1 Shows the air tight valves closed, so no sound at all is conveyed through the tubes. No. B. shows. the valves open ready for two persons to listen. 'A nickel passing through the slot opens the valve. It requires one nickel to open oaoh 'valve. The valves are closed by the carriage as it returns, it is exceedingly sim¬ ple and a sure worker, and it can be placed on any nickel-in-tho- slot machine. It is held in placo by body screw of phonograph.

It is thought that this device will double the earnings of the nickol-in-the-slot phonograph. It is proposed to furnish this device complete (two tubes); for five cents per day, or §1.50 per month, payable monthly, contract to continue for one year. Ordors can bo filled in about twenty or thirty days. We will bo glad to receive your order for as many as you think you can use to advantage.

Would you kindly look over the same and if correct, send them with a few lines ' to Mr. Insull and secure his signature and have him return the same to me. As he was not present at the last meeting and you were his substitute, I think it best to have him sign the Minutes of the proceeding.

You no doubt received a circular from Mr. Price regarding the lecture on Thursday evening next at the Electric Club to be . delivered by Professor Hioolls of Cornell University on the "Artificial Light of the Future! As this promises to be a very interesting lecture and no doubt would be worth listening to, I thought perhaps you might find time to come over 'if you have noth¬ ing better to do. If so, I will meet you Thursday evening, art we can have that promised dinner together, at the Club and then listen to the lecture* Perhaps if Mr..

Hesr York City, Decenber 1st, 1890.

Automatic Phonograph Exhibition Company,

Felix Gottsohalk, Esq., President.

Dear Sir:

Re Pending Applications for Patents and Patents and Assign¬ ments thereof to you.

I bog to submit for your information the following statement of how these things now stand:

(1) on October 15, 1890, I sent to the Patent Office for re¬ cord, assigments from the Exploiting Company to you, of patent Nos. 438,750 and 428,751, and of application for patents of Glass and Arnold, filed Feb. 15, 1890, serial No. 340,027, for joint inven¬ tion for Numis Motor Phongraphs, On October 25, 1890, I received from the Patent Office notice that these assignments had been re¬ ceived, and that they would be recorded in due course. No doubt the Patent Office will return the said assignments to me within the next week or so. But you can consider the assignments as hav¬ ing boon duly recorded as of the date when they were received by the Patent Office.

(24 In. addition to the above two patents and one application, you are interested in three other applications, as follows:

(a) S. H. $40,687, joint invention of James F. Gilliland and A. K. Keller, application for patent filed in the Patent Office Fob. 17, 1890. This invention, the whole of it, was originally assigned by tbSse two joint 4nve3K&nB, to Ezra T. Gilliland on Jan 31, 1890, which was before the application was filed. Th>v*tt|fcd


Gilliland on Fab. 10, 1890, assigned the whole of the same to you, which was done sIbo before the application was filed. Under the rules of the Patent Office the aforesaid two assignments c-ould not be recorded, because they failed to state the date of the filing of the application. In fact the application was filed after the assignment of the invention. In order to cure this defect, a new assignment ( to take the place of the old one made on Jan. 31,1890, as aforesaid) was made by James F. Gilliland and Albert K. Keller to Ezra T. Gilliland, by written instrument dated November 11, 1890. Unider dA"tO“ of Nov. 14, 1890, the said Ezra T. Gilliland made ah new

assignment ( to tako^he^ place of the aforesaid assignment of Feb. 10, 1890) to you. Hte^two last named assignments are now in my

possession, and I shall forward them at once to the Patent Offico for record, viz: Assignment a of Nov. 11, 1890, from James P. Gilli¬ land and Albert K. Keller to Ezra T. Gilliland and Assignment of Nov. 14, 1890, from Ezra T. Gilliland to you, both assignments re¬ lating to serial No. 340,687. This will give you a complete title to the whole of these applications and will result in the patents when thoy are allowed, boing issued to you, as assignee of the in¬ ventors.

£/v Wojjr

(b* S&M52S& invention of Ezra T. Gilliland relating to im¬

provements in automatic locking and releasing devices. This applfc cation has been allowed and Mr. Kiddle is about sending final fee to the Patent Office in order that the patent may! isSue at Once. This assignment was originally made for the whole of the invention, by instrument dated Eeb. 10, 1890, but in consequence of the date of the application not having been mentioned in that assignment, because the application was really filed after the application was made, a new assignment has been executed by Mr. Gilliland under

^at0 of * 1890 Mr* Kiddle will forward this assigment, to the


Patent Office at once, when he sends the final fee as aforesaid.


•« =x latesta-dine Of the tatter 1. ,tot the p.teht .in ierao

in your name aB assignee of the said Gilliland.


(c) S.N. U&ppps., application for patent filed March 6, 1890, joint invention of Prank W. Toppan and K^ra T. Gilliland, for attachments for automatically operating phonographs. The said Toppan owned one half of this invention, and the said Gilliland owned the other half. The latter half was sold by Mr. Gilliland to the North American Phonograph Company, which, X believe, owns it, and holds the title to it. The said half of Mr. Toppan wan ass¬ igned to you by instrument dated Feb . 10, 1890, now in mjV possess¬ ion, but inasmuch as this instrument does not contain date of fil¬ ing application, Which was really at a X^date, March 6, 1890, a new assignment must be made by Mr. Toppan to you. This document has been drawn and is now held by Mr. Kiddle awaiting Mr. Toppan's return from Europe when he will execute it and it will then be. re¬ corded. i should here state that as regards this assignment and the one mentioned above, wherein the dates of filing applications were omitted, the assignments themselves are valid in law notwith¬ standing said omissions, but they cannot be recorded in the Patent Office owing to its peculiar rules. This is a matter which merely relates tp convenience of record but does not Effect the validity and legal force of the assignments themselves.

(8) So far as I know, your present interests in patents a«l and pending applications are limited to the applications mentioned *ove in subdivision (2, and to the two patents and one application mentioned above in subdivision (1). But in saying this * shall, put in a saving clause as regards subdivision (1), viz: that owing to my lack of eft definite information touching the applications of Glass and Arnold, I am in some doubt whether their applications to which you are entitled, were five in a-. ^


But I boliovo that the latter is the fact. To the best of my in¬ formation, Glass and Arnold made three applications for patents, to wit: S.N. 334,196, filed Decontoer 18, 1889; S.1T. 339,069, filed Fob. 3, 1890; and S.N. 340,627 filed Feb. 15, 1890. These throe of the30 applications all became your property. On the first tvfo^ patents havo been granted. On the last' application no patents has yet boon allowed . Does this agroo with your understanding? 1 Ke-


fee? 1„ it is so.

(4) Referring now to the last named application of Fob. 15, 1890, S.N. 340,627, of Glass and Arnold for inventions for Numis Motor Phonographs, that application has been put in interference with the aforosaid application of Ezra T. Gilliland and Frank W. Toppan for attachments for automatically operating phonographs S.N. 342,875, filed March 6, 1890.

As regards the said application of Gilliland and Keller No. 340,687, three interferences were declared last week, viz. Inter¬ ference No. 14,846 with H.R. and T. Conyngton of Gal vest an and H. Hooschen of Omaha, to an electric oirouit for operating phonographs normally open at two points and closed by the contact of a coin; interference No. 14,847, with the aforosaid Conyngtons, relating to moans for breaking the electric oircdit at the end of the move¬ ment; and interference No. 14,848, withW. S. Burnett, relating to mechanisms for starting and stopping the motor and for a lifting devioe for the arm.

As regards the said application of Gilliland and Toppan, S.N. 342; 875, three interferences were declared last week, viz: Inter¬ ference No. 14,625 with Glass and Arnold, relating to means for holding up and lowering the arm; interference No. 14,842^8Rjf&^S:., Clark of Pittsburgh and E. E. Flora of Chicago, and Glass and


Arnold, for means for raising tho arm; and interference Mo. 14,844, with John Ott, of Orange, relating to the raised position of the arm and tripping devices.

(5) Referring again to tho interference mentioned above in the first part of subdivision (4), viz: interference between S.N. 340,627 of Glass and Arnold and S.N. 342,875 of K. T. Gilliland and Toppan, there is a question still open which needs attention. Tho subject mattor of this interference is this:

A phonograph comprising a box or case, a phonogram cylinder mounted thereupon, a reproducer, a feed and return mechanism for said reproducer, an armature, eccentrically connected v/ith said food and return mechanism, and a magnet acting upon said armature and adapted to automatically and alternately reverse said mechanism

Tho Patent Office holds that tho foregoing issue is covered by all of the twelve claims of the Gilliland and Toppan application, but by only the first of the fourteen claims of the Glass and Arn¬ old application. Both applications are now owned toy. the same party except as regards certain pacific coast territory. That toeing so, the subject matter in interference can be by consent erased from either one of the two applications if it be desirable to dispose of tho subject in that way, although it should not be erased from the former application because all of the twelve claims thereof would bo affected. If an erasure be made, it from the Glass

and Arnold application, because only the' first of its fourteen claims would be affected.

Why get rid of tho interference by erasure? ^hy not let both parties to the interference file sworn preliminary staten^nts acting up dates of invention, and then let the Patent Office award priority? This last course, is open to the objection that tho actual dates of iwontion would become a matter a-r _ ,,


in tho Patent Office, and we might possibly have reason to regret much publicity, in the fhturo.

TOiy not have both parties to this interference prepare their final statements, setting forth the actual dates of invention, and lot us then, without filing tho said affidavits in the Patent Office^ ourselves award, so to speak, priority to tho earlier inventor?It seems to me that this is tho best course, because it provides us with a sworn statement of the actual dates of the inventions, which ttay be of value to us at some fhturo time in the event of litigat¬ ion with infringers. Wo have asked Glass and Arnold to supply us with this affidavit, but they are unwilling to do so. They prefer that wo should settle this interference by erasure, by consent, as mentioned above. for some reason they do not wish to puton paper the dato of their invention, and swear to it. Possibly their arrangements with the Exploiting Company^ as aforesaid provedsit to be less remote than was expected. Be that as it nay,
