' Application filed August 3, 1917.

To all whom it may concern:

' Be it known that I, GnonenA. Lone, a citizen of the United States residing at Hartford in the county or IIartford and State of Connecticut, have invented certain new and useful Improvements of Transmitting Intelligence, of which the following is a specification.

This invention relates to a system of transmitting intelligence. Preferably the system comprises a'plurality of stations, one or more constituting for instance subscribers stations and another a central stafurnished with equipment such as a telephone and through the agency of the subscribers the latter may talk or otherwise communicate with each other, through the intervention for instance of the central ofi ice operator or in some other manner. At each subscribers station is another instrument by which the also communicate with ofiice operator. In the present instance these additional instruments are what are known astelautographs. The various under proper control, communicate audibly with each other or with central, and in addition may transmit messages of a different type,- which ments are utilized, are written. This system may be employed in difierent ways, for example'for the transmission of telegrams which come into a telegraph ofiice, having,

of course, telephone equipment, by the way of a proper telautographic or equivalent instrument. I provide means whereby these conditions are made possible and wherein I also provide for the collection of the proper amount or toll.'As a matter of fact there are other advantages attained by me which I will more explicitly hereinafter outline. I will also set forth in detail that form of embodiment of the invention which I have selected for illustration in the drawings accompanyfication. This isclosure is primarily made to enable those skilled in the art to practice the invention. I am not restricted thereto, because I may depart therefrom in certain Specification of Letters 2mm.

particulars within the scope of the invention defined by the claimsto'llowing id description.

In the drawin s are four views identified respectively by 1 and Fig. 1, showing a system involving the invention. Theillustration for simplicity is divided but the figures collectively represent the system and indicate the nature of the invention.

its may be inferred there is a main line or main circuit. This ma obviously be of any convenient character. denoted in a general way by 2. It is the present-day telephone line, although. as will be clear the invention is not necessarily limited' in this and other particulars. The power to the line 2 may be supplied in any of the usual fashions.

In, addition to the main or primary circuit 2, there are several auxiliary or subordinate circuits as will hereinafter more par-. ticularly appear. The nature or the instruigure 1, Fig. 1", and Fig;

hat partly shown is are shown) may also difi'er. I prefer, however, to employ a plurality of st'ationseach equipped with a telephone, the subscribers of which can get into telephonic communication with each other through'the central ofiice. Beside this the stations, as distinguished from the central oflice, are equipped with instruments other than a telephone, and these instruments are generally and advantageously in the form of telautographs.

- In Fig. 1*" I have shown a subscriber.s station- 3 furnished with equipment as will hereinafter appear. The subscriber is connectible with the central ofiice or station 4.- In Figs. 1 and 1 I have shown cord con- In Fig. 1 I have shown another subscribers station which in this case is supposed to be a telegraph ofiice. I have not'shown, however,

i any of the telegraphic sending instruments in the last mentioned-view, as in the pres.

I cut case they do not-necessarily concern'the invention. I have, "however, illustrated in said Fig. 1 the telephone circuit and the telautograph circuit and the necessary cooperating instrumentalities.

Proceeding now with the description of Fig. 1 and more especially the part to the left thereof, the numeral 5 denotes a telehone and the numeral 6 a telautograph. he telephone instrument is well llIldJGT- stood and the. same statement applies with respect to-the telauto%aph which has been the subject of several S. patents. Therefore, it is not necessary for me to describe in detail either instrument, except in a general way, and sufficiently to point out the action of the system.

The telephone equipment at the subscribers station comprises a transmitter 7, a receiver 8 supported by its hook 9, the induction coil 10, condenser 11- and a ringer 12. It will be clear that normally the telephone circuit is open. When the subscriber takes his receiver 8 from the hook 9 the latter is released and closed generally automatically, by spring means, to thus close the telephone circuit and cut it into the line 2. This will result in lighting the lamp 13 at central office 4 and will indicate to-the central office operator that a subscriber is on the line. It will be, of course, understood that the central office equipment is shown partly in Fig.-

1 and the remainder in Figs. 1 and l and partly in Fig. 1. As I have noted, when the subscriber at the station 3 takes his receiver 8 from the hook 9, the telephone circuit at-the station 3 is closed 13 at the central ofiice station 4 will be lighted. When said lamp is lighted, this apprises the central office operator that the subscriber desires something, and as a consequence she will insert her plug into the proper jack.

denoted by 14 "on the right of Fig. l, and as I observe'when the lamp 13 is li ,hted as alluded to, she inserts the plug 15 ig. 1*) into the jack 14 and her head telephone 16 being on, she can get into telephonic communication with the subscriber, through the transmitter '17 at the station 3, when she operates the listening key 18 (Fig. 1). The

connection between the central office station- 4 and the subscriber 3 is of course, made over the line 2. I

In Fig. 1 -I have shown a station 19.

This station is supposed to be a telegraph ofiiceequ'ipped of course, with the necessary instruments for the receipt and transmission of telegrams, which, however, I have not deemed it necessary to illustrate as they do not in themselves concern the invention. At the station or telegraph office 19 there is 'a set20 made up of the usual receiver 21 and transmitter 22.

;It will be supposed that the subscriber at station 3 desires to get into communication,

with the subscriber at the station 19, this having been determined previously by the insertion of the plug 15in the jack 14. To put the two stations 3 and 19 intotalking connection the following procedure may be adopted: The central ofiice operator will and the lamp these.

The jack in question is that.

first determine whether or not the station 19 is busy, in this case for example by touching the tip 20 of the lug 20 associated with the cord pair which she is using, to the vsleeve of the jackof the line called for,

operator operates the ringing key 22 (Fig. 1).

When the subscriber at the station. 19

hears the bell 23 he knows that a subscriber desires to talk with him, and he, therefore, communicates with the subscriber at the station 3 by operating the talking key 24 (Fig. 1 and determines the wishes of the party at station 3. It will be assumed that the party at station 3 desires to send a telegram. The modeof procedure to accomplish this result will be hereinafter set forth.

I might say that I have but briefly described the telephonic connections between the two subscribers stations and the central office. The invention does not necessarily concern As aresult they have been described quite conciselv but with the statute. I have not deemed it necessary to even describe the additional jacks nor to refer to conditions which ensue when the line is busy. I might observe that the jacks 25 and 26 which appear in Fig. 1 are quite common in standard telephone equipment. It has not been thought necessary to allude to their functions because they are so well understood. x

The subscribers station 3 as I have already explained is furnished with a telautograph which appears in Fig. 1 In Fig. 1 atthe second subscribers station which in this case is a telegraph office, is a similar telautograph 27. The telegraph ofiice atyet sufficiently to comply I tendant upon ascertaining that the sub-f scriber at station 3 desires to send a telegram says in effect Hang up the receiver which in this case is the receiver 8 (left of F i 1) Start the tel-autograph machine as% will hereinafter point out, And write your telegram. After .you have. finished writing your message stop the telautograph and take the receiver from the hook and wait until I can tell you what the charge is. As the calling party at station 3 carries out these instructions the telegraph ofhce attendant restores the talking key 24 to normal and operates thekey 27 (Flg. P), which cuts the telautograph in onto the line 2 and cuts out all the telephonic apparatus at the telegraph oflice for the time being. By placing the receiver 8 back onto the hook 9 the relay 28 (Fig. 1") releases,'opening'the local circuit to one windin 30 of the double wound relay 31, (Fig. 1 This removes the shunt from around the answering supervisory lamp 32 which lights and shows that the receiver 8 has been hung up on the hook at station 3. As soon as the telegraph office attendant operates the'telautograph key 27 the ground side of battery 33 (Fig. 1) is removed from one side of the line 2 and the ring strand of the cord circuit, so that the armature of relay 34 falls, opening the circuit to the other winding 35 of the .double wound relay 31 which then becomes inoperative, and its armature which has been drawn u until this time releases, making contact with contact 36. Releasing of the armature of relay 31 makes a new circuit not heretofore established. The relay 37 (Fig. 1)

being already energized, the ground side of.

38 is connected at 39 and 4.0, thence 36 and 41 of relay 31, to contacts (Fig. 1") which is not 45 and d6 of relay %7 battery to contacts 42 and 43 of relay 4A operated, to contacts which is operated, to one side and through the' winding of each of relays l8 (Fig. 1 and 49 (Fig. 1) to the negative side of battery 50. This closed circuit energizes relay 48 (Fig. 1") connecting contacts 51 and 52 and 53 and 5% respectively in relay 49 (Fig.

connecting contacts 55 and 56, and 57 and 58 respectively. As will-be understood the two relays to which I have just referred are operated in,synchronism. This operation cuts off practically all the apparatus associated with the operators cord circuit and 1) andestablishes a metallic connection from the subscribers station 3 (Fig. 1) to the telegraph ofiice (Fig. 1 The resistance 59 connected to the negative side ofthe battery 60, the positive side of which has a ground connection, keeps the answering supervisory lamp 32 extinguished by shunting it as soon as contacts 61 and 62 of relay l8 (Fig. 1") are made. A similar function is performed when relay 49 of Fig.

' 1 is operated as the resistance 63 connected with the negative side of battery 64 shunts out the calling supervisory lamp 65 as soon as contacts 67 and 68 make connection So long as relays48 (Fig. 1") and 49 (Fig. 1) are operated, the supervisory lamps 32 and 65 will be dark, and if neither of the plugs is removed from the jacks, no interference or interruption will be experienced as the subscribers operator cannot listen or ring on the circuit. It will thus be possible for the calling party a message on the telautograph 6 at the sending, end, which will be transmitted to and re-' produced on the telautograph 27 at the station 19 (Figrl At this point the subscriber at station to aph 6 in action, operates the stylus 69 of said telautograph (assumed to be a sending actual collection of the money 18 un control of the telegraph operator. have thus far described the system and up" at station 3 to then write 3 after setting the telau-' telautograph), the writing being reproduced by the stylus .70 of the receiving telautograph 27 in the telegraph ofiice of station 19 (Fig. 1

When the calling party completes writing the message ciatccl with the telautograph 6 will be operated to cut out said telautograph and the receiver 8 will be taken from'the hook 9 by the party at station 3, ready for verbal verlfication of the message and information relative to the charges from-the attendant at the telegraph oilice. vThe party at the receiving station 19 has in the meantime restored the telautograph key 27 (Fig. 1)

to normal and operated the talking key 24.

of machine known as a prepaymentte e phone. V

A toll collector which meets my conditions in a satisfactory manner is such a one as is used with a telephone pay station. Some of these instruments collect the toll before the message is sent and some after. By this I mean after the verbal or before the verbal message is sent as distinguished from a telegram. As I already note a telephone pay station which is of one I prefer naturally to use. An illustration of such a machine is set forth in Letters Patent No. 917,742 granted to me April 6,

' 1909 and to which reference may be bad.

This machine is diagrammaticall illustrated in Fig. 1 and is fully disc osed in said patent.

As I have stated after the telegraphic message has been sent in the present case the starting switch asso-- .the' prepay type is the v from telautograph to telautograph,the-next proceeding is the collec v toll. While the amount necessary to be deposited is named by the telegraph office the As I to the resent moment, the control of the system is for the time being under the control of the operator at the telegraph office. As will be understood a telephone pay station at the present time involves signals of distinct character which are sent over the line through the receiver in resonant conder the I tion of the necessary nection with the signals to central office or telegraph operator.

deposit of a nickel, another a dime and another a quartenthese bein the usual signals atpresent in vogue. They may be as will be inferred, transferred exactly in the manner set forth in the Letters Patent granted to me and already identified. Upon hearing the money signals and being satisfied that the proper amount of funds has One signal indicates the charges have'been paid for satisfactorily and the telegram will be sent at once. As soon as the calling party at station 3v hangs the receiver 8 on the hook 9, the party at the telegraph oflice or station 19 will press the coin collect key 71 (Fig. 1 sending 110 volt positive current through the resistance lamp 72, relay 73 onto the tip side of the line 2 to the tip spring 74 of jack 21"to the tip of the plug 204 and tip of the operators cord circuit tothe tip spring 75 of the jack 14 to the tip side of the line 2 through the subscribers station 3 (Fig. 1 through the coin collector coils 76 through the contacts 77 and 78 to ground. This closed circuit not only deposits the money into the cash box but also operates the relay 73 (Fig. 1 which lights the red pilot lamp 79 associated with the coin collecting circuit, and shows the telegraph ofiice attendant that the coin collector has been operated and the money has been collected.

The calling party at station 3 has already put the receiver 8 back onto the hook 9, while the attendant at the receiving end restores the keys 24 and 71 to normal and operates the ring key 80 which sends out grounded generator current to the tip side of the line 2 and tip spring 74 of jack 21 and plug 20, and tip side of cord circuit (Figs. 1 and 1) to' contact 52 of relay 48 to condenser 81 through the winding of relay 82 to the ground. This operates relay 82 and connects contacts 83 and 84, putting ground onto one side of the winding 85 of the relay 44 through the winding of relay 44 to the negative side of the battery 86. This operates relay 44 which looks up until the answering plug 15 is removed from the answering jack 14 of the subscribers line (Fig. 1). Looking up relay 44 is caused by the ground on contact 87 (so long as relay 47 is operated) engaging with contact 88 of relay 44 which is connected to one side of the winding 85 with the negative side'of the battery 86. The operation of relay 44' opens contacts 42 and 43 and removes the ground from the windings of relays 48 and 49 (Figs. 1 and 1) which release and restore the cord circuit (Figs. 1 and 1) to its normal telephonic condition; that is with the receiver 8 on the book 9 at the calling station 3 the answering supervisory lamp 32 (Fig. 1") will be lighted. As soon as the telegraph office attendant 19; (Fig. 1) restores all the keys to normal and relays 48 and 49 (Figs. 1 and 1) release, the calling supervisory lamp 65 should light, signaling the central office operator that the connection may be taken down.
