1 tent electric currents, and to effect impressions from either type-wheel at will upon a receivingtape or sheet of paper. The limit of speed with which such instruments may be operated is usually determined by the ability of the operator to handle the transmitting apparatus, rather than by the capability of the receivinginstrument to respond to the transmitterthat is to saythetype-wheels are capable of'bringing the characters into position to print with greater rapidity than it has been found practicable for the tra-nsniitting-operator to select and print from them.

In telegraphic communication, of whatever character, it usually transpires that. during 0 some portion of the day a greater amount of business is required than during other por-- tions, so that'an instrument capable of meeting the requirements at certain times is not capable of doing so at other periods. A spe- 3 5 cial instance of this is found in recordingstockquotations. Usually a greater amount of business is transacted at the exchanges during the first hours of the day than during the latter portions, so that althougha single stock- 40 printer is sufficient to record the transactions which may occur during certain portions of the day, yet at other times it is inadequate to the demands occasioned by the greater number of transactions occurring at once. More- 5 over, it is usual that in the busier portions of the daya great many sales occur simultaneously, and it is desirable that these should be reported as quickly as possible. Other instances where the amount of work to be done the same office.

by printing-telegraphs is variable are found in news-reporting and press-dispatches. r The object of this invention is, therefore, to provide means whereby; by the addition of a few instrumentalities, the increased demandsv may be accommodated as they occur, andalso to provide means for separating the different classes of reporting which are to be made from Thus, for instance, it is often desirable to print the stockquotations upon one slip or tape, and the transfers of bonds and special securities upon one or more independent tapes, and to accomplish this without materially, if at all, retarding the operation of the instrument when employed for printing upon a single slip.

In general terms, the invention consists in adding to a printing-telegraph instrument, which in its general structure resembles any of the wellknown forms, additional typewheels carried upon or connected with the same shaft and revolved by the same instrumentalities heretofore employed. These additional type-wheels are provided with similar apparatus for printing from either typewheel at will, so that during the time that is necessarily lost in selecting the different transmittingkeys and effecting impressions from one set of type-wheels one or more additional transmitters may be operated and impressions effected from the additional typewheels. Each printing device is included in an independent line and providedwith its own transmitter, so that currents are sent to the different press-magnets either at the same or different times, accordingly as impressions 8 5 are to be effected by both simultaneously or at different times.

In carrying out the invention certain modifications and adaptations of both the transmitting and receiving apparatus are essential, and a description of an organization of apparatus adapted to the purposes of the invention will be given in connection with the accompanying drawings.

In these drawings, Figure l is a digram 5 illustrating the organization of the transmitting apparatus, showing the circuit-connections. Fig. 2 is a diagram of the receiving are employed, and the currents caused by themto traverse the respective lines L and L are employed for operating independent-printing devices applied to two sets of type wheels, T

and T, carried upon a single type-wheel shaft.'

It may here be remarked that the invention is not, however, confined to two sets of transmitting devices and the typewheels, but may be extended, as will be evident from the following description. The movements of the shaft T are controlled by currents transmitted over a line, L.

The means whereby the variops classes of currents are transmitted will first be described. A transmitting-shaft, A, is revolved by any suitable power, and is capable of being arrested in any required position by a series of levers, a a and a a. These levers are employed for transmitting printing-currents, and the printingcurrents are either positive or negative, according as it is desired to print from one or the other of the corresponding type-wheels, and they also determine the particular character to be printed by determining the position in which the shaft A shall be arrested. There is carried by the shaft a circuit-controller or pole-changer, 0, adapted to transmit alternating currents to the main line L from two batteries, 0' and 0, for the purpose of operating the escapement of the receivingiustrument. The pole-changer preferably consists of two series of alternating conductingsurfaces, 0 and 0". Two brushes, 0 and 0 respectively, connect these surfaces with the positive pole of the battery 0 and the negative pole of the battery 0 Theremainin'g poles are connected with the earth at G by a conductor, 1. A brush, 0 extends over both -series of segments and makes alternate contact therewith. This brush is connected with the main line L, and in this manner a determinate number of alternating impulses is sent to the line L at each revolution of the shaft A. These secure a revolution of the typewheel shaft Tfor each revolution of the trans mitter-shaft A, the number of conducting and intervening non-conducti ng surfaces being dependent upon the number of characters or type upon each type-wheel, and determined in the usual manner.

Opposite each conducting-segment there is formed an indentation or notch, as shown at d d, upon one'side of the commutator, and a second series is arranged in like manner upon the other side. Each of these series is arranged in a spiral line, so that one revolution of the shaft will complete one turn of the notches. These notches serve, in' connection with the levers a and a, to arrest the trans mitting-shaft in a position dependent upon the particular lever operated,aud thus each notch will represent a particular character upon the type-wheel. When any lever is actuated, the

shaft will continue to revolve until the notch in line with that lever comes beneath its end, whereupon the lever will drop into the notch and hold the shaft until the leveris withdrawn. This movement of any lever not only arrests the shaft, but serves to transmit a current to the corresponding line, L or Lflfrom the corresponding battery, 0 or O", as will hereinafter appear.

The levers a a are each provided with an actuating electro-magnet, as shown at b b,and these are vitalized by currents from abattery, p or q, accordingly as a key in a division, j or k, in the series K is operated. For this purpose the keys j, which, respectively, correspond to the'characters upon the letter typewheel Nof the set T, are provided with contact-points connected by a conductor, 2, with the positive pole of the battery 1), and the keys in the division k are provided with contact-points connected with the negative pole of the battery g by a conductor, 3. The re maining poles of v these batteries are connected by a conductor, 4, through the coils of an electro-magnet, F, with a conductor, 5. The levers of the keys in the division j are respectively connected through the coils of the respective electromagnets b, applied to the levers a. The conductors leading from these magnets are united with the conductor 5. The levers of the keys in the division k are respectively connected with the conductors leading from the levers of the division j,and thus each magnet may be vitalized either by a key in the division j or the corresponding key in the division k. The currents transmitted through theconductor 4, and thus the electromagnet F',will, however, be one of polarity for one division of keys, and of the opposite for the other division. This difference of polarity is employed for moving the polarized armature f of the magnet F against a stop,g or h, and thereby determining whether a positive current shall be sent upon the line L from a battery, O, or a negative current from the battery P. The polarity of the current sent determines whet-her printing shall be efl'ected from the letter or figure wheel of the set T. The connected keys,therefore,of the divisions j and k, respectively, correspond to the characters located in the same radial lines upon the a two type-wheels.

Each lever a is provided with a contact-stop,

i. The levers themselves arenall connected with the main line L. The contact-stops are connected by a, conductor, 7, with the polarized armature f,and the contact-points g and h are respectively connected by conductors 8 and 9 with the positive pole of the battery 0 and the negative pole of the battery P. The remaining poles are connected with the earth at G. It will be seen,therefore,that accordingly as the lever f is thrown against one stop or the other the battery O- or P will be connected with the contact-stops 11. Any lever a, however, which may have been acted upon by its magnet b will not come into contact with its stop i until the' corresponding" depression in the cylinder A comes beneath its hooked end, which then falls into the notch and arrests the cylinder. Thereupon the lever is allowed to approach its magnet, and the cylinder is arrested and contact'made with the corresponding stop 2''. It is desirable that the transmit ter shall be' released and the shaft allowed to again advance the moment an impulse has been sent from either battery 0'. or P. This may be readily accomplished by causing the inrpulse to vitalize an electro-ma-gnet, l, included in the conductor 7, and provided with a polarized armature, Z. The armaturelever Z is connected with the conductor 4,and its respective contact-points u and v are connected with the conductors 2 and 3. This armature will make contact with one or the other of these stops,accordingly as a positive or a negative current is sent to line, and the connections are such that it will then short-circuit the battery p or g, by means of which the cylinderis arrested and the current sent. The lever a will thereupon be released and thecylinder A again advanced. The magnet I may be made to respond more or less slowly, as required. A spring, 41,, holds theleveraway from both stops when no current is upon the line L.

The other transmitting device, A applied to the shaft A, is precisely similar to that described, and the corresponding parts are indicated by corresponding letters ofreference, having the numeral 2 affixed thereto in place of the numeral 1. i

It is designed that the currents transmitted by the pole-changer 0 shall operate the escapement-anchors of the receiving-instrument, and that the currents transmitted upon the line L from .the batteries 0 and P shall operate printing and platen shifting devices applied to the type-wheels N and M. The currents sent upon the line L from the batteries '0 and P efi'ect impressions from one or the All of these type-wheels are mounted upon the shaft.

other of the type-wheels N and ll/P.

characters which then confront the printingpads t and 23 respectively applied thereto, will correspond to the keys employed for ar resting the transmitting-shaft insuch position. The current which is transmitted over the line L or L at the moment the shaft is thus arrested will be either positive or negative, according to the key which is actuated, and the character of the current will determine from which type-wheel, N or M, impressions shall by an electric motor.

be effected. This result is conveniently accomplished by employing a polarized armature, s, carrying at its end a flexible extension, 8 upon which is mounted the printing-platen t.

An electro'magnet, S, includedin the main line L, acts upon this armature and impels it in one direct-ion or the opposite, according to the polarity of the current transmitted. Thus the platen is moved from its position beneath one type-wheel to the other type-wheel by a reversal-of the current. A press-magnet, U, is also included in the line L, and this magnet responds to the currents from either batis being made from either type-wheel N or M an impression may be taken of either of the ch'aracters'upon the other type-wheels, M or N, which then confront the printing-platen t and that while the transmitter is operating to transmit a message composed by one transmitting-operator it also transmits that composed by the other operator, so that there is no delay due to unnecessary movement of the typewheels, and impressions willbe taken from one or the other set of Wheels, or from both at thesame time. c

It is not desired in any way to restrict the application of the invention to the precise organization shown and described, as it is evi- 'dentthat other means may be adopted for transmitting the proper electric currents for determining from which typewheel the impressions are to be effected, and also that the special apparatus described for arresting and releasing the transniitting-cylinder may be replaced by other devices. For example, instead of arresting the transmitting cylinder by the arm a, when a printing impulse is to be sent, both sides of the depressions d may be cut away or curved, as indicated in dotted linesin Fig. 5. The levers a will then merely fall into the depressions and .be again lifted out after the impulse has been sent. In this manner impressions are effected without stopping the cylinder and the type-wheels. Again, it is not necessary that a mechanical escapement for the type-wheel shaft be employed, but the position of the type-wheels may be determined In practice, however, the operators usually become so skilled that they release the keysthe moment they transmit their impulses, and so there is no delay occasioned by one of them stopping the instrument an unnecessarily long time.
