TELEGRAPHIC SENDING DEVICE.

Specification of Letters Patent.

Patented June 19, 1906.

Application filed January 27, 1903. Ser al No. 140,718-

To all whom, it may concern..-

Be it known that I, ISIDOR Krrsnn, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Telegraphic Sending Devices, of which the following is a specification.

In the drawings I have selected as the best method of explaining my invention the adaptation thereof to a use which I now directly contemplateto wit, the signaling from the various car-barns of a street-railway system to the central ol'lice of such system. The information which it is desired to convey in such systems may comprise, for instance, the following details: the number of a car which has started or is about to start from a given barn, the number of the conductor in charge thereof, and the trip-number of the car.

As the reports from the various barns are made at short intervals and may often occur simultaneously, the conveyance of this intel ligence by telephone would require the presence at the central office of a number of telephone operators to receive and record the niultitudinous messages. If, on the other hand, ordinary telegraphic apparatus be employed, even though the receiving element at the central office be automatic, itis still necessary that at each barn there should be a skilled telegraph operator capable of transmitting the messages.

The economical object of my invention is to provide a telegraphic apparatus having an automatic receiving element and having a transmitting or sending element, which, while it affords the necessary variety of signals, shall be so simple in its method of manipulation as to require no telegraphic skill what- Thus any ordinary workman who can read numbers is competent to transmit messages which will comprehend all the required information.

As it may be desirable to employ an apparatus in conjunction with a telephone-line between the barn and the central station, (in order to permit verbal conversation, where the transmission of other than the ordinary messages may be necessary,) I have shown and described the system so organized that a portion of the telephonic circuit is utilized for the telegraphic connection.

In order to avoid confusion in nomenclature between the elements of the telephone system and those of the special or telegraphic system of my invention, I shall designate the former by the usual terms, such as transmitter, receiver, &c., and the corresponding elements of the latter by the terms sender and recorder.

In the drawings, Figure 1 represents diagrammatically such a combined system extending between a single car-barn and the main or central oilice, it being understood that in practice a number of such systems will be employed to connect with the various barns. Fig. 2 is a front elevation of the sending apparatus, showing a movable member placed in alinement, the others in their normal positions. Fig. 3 is an enlarged horizontal section through a portion of the board. Fig. 4 is a vertical section through the sliding block.

In order to readily explain the general nature of the system shown in Fig. 1, it will be convenient to ignore for the time being the details of the sender and recorder, simply understanding for present purposes that the former is capable of electrically transmitting a plurality of successive signals of definite character by appropriate mechanism and that the latter is capable of recording said signals, as, for instance,upon a paper ribbon.

Referring now to Fig. 1, A indicates the group at the car-barn, and B the group at the central office, C C indicating the line-wires of the metallic telephone-circuit between the two points, and F the battery. At the group A the telephone is shown as ordinarily constructed, the transmitter thereof being indicated at a, the receiver at a, and the springhook for the latter at (L2. The contact-terminal for the hook in its released position is shown at a, the call-bell at a", and the condenser for operating said bell at a.

At the other end of the line 1) indicates the telephone-receiver, I) the transmitter, b the magnet of a relay whose armature b is adapted to close a local circuit from a battery f, so as to energize a signal-lamp b.

A magneto-electric machine f is provided for signaling to the other end of the line, an ordinary switching device to throw the same into and out of circuit being indicated at b. All these parts are represented conventionally,

and the system thus indicated may of course be varied in any desired manner.

From convenient points of the main telephone-circuit shunt-wires D lead at the respective ends of the line to the special or telegraphic apparatus characteristic of my invention, the sender of which is indicated by the group of elements at E and the recorder by the group at E. From the proper elements at each end of the line wires G G, respectively, lead to the ground.

A switch d may be provided, whereby the telegraphic system can be thrown out of circuit, if desired.

When the telephone-line is to be used as such, the removal of the receiver a from its hook a permits the closing of the circuit at a and by means of the relay b gives the signal for telephone conversation by the illumination of the lamp 5. Similarly, when it is desired to telephone from the central office at B to the barn at A, the magneto f being actuated, with its switch 6 in proper relation, the bell a will be rung by reason of the action of the condenser (0 whereupon the talking-circuit can be utilized in the ordinary way. It will be understood, however, that the above-described embodiment is only typical and has thus been set forth because it represents an obvious and convenient adjunct to the system.

Referring now to the special or telegraphic apparatus characteristic of my invention, its main elements are a sender and a recorder. The latter of these two may be an ordinary Morse instrument having a paper ribbon, which is kept constantly moving by clockwork or other convenient device and provided with an element capable of producing upon the paper marks whose length and relation to one another have a predetermined significance and which are in accordance with the currents successively transmitted from the sender.

The details of the sender will now be described by reference to Fi s; 2, 3, and 4, the instrument being adapte for the transmission of three sets or groups of signals.

K is the base-board upon which the sending instrument is mounted.

L, L, and L are stationary conducting members secured to the base-board, each of these members being provided with raised portions representing predetermined and definite words, as designated at M, which raisedportions I call bars, and at the right of each of these members are arranged a certain number of movable conducting members N, each of these movable members being also provided with raised portions which may be conveniently described as dots and dashes, the dot being approximately onehalf the length of the dash and the dash, say, one-half the length of the shortest bar upon the stationary members. The dots range in value from one to five, designating the numerals 1, 2, 3, 4, and 5, and the dashes range in value from six to ten, designated by the numerals 6, 7, 8, 9, and O but whereas the raised portions on the stationary members are arranged in one line each group of raised portions designating a numeral on the movable members is given a separate line thereon.

The movable members are guided in suit able guideways, as represented at O, and are normally held upward by springs or weights P.

Arranged upon the base-board K, directly beneath each of the movable members N, are pins or hooks Q, in number equal to the number of groups of raised portions on the member N, each group designating one of the numerals O to 9, inclusive.

R represents connections extending from the movable members and terminating with an eyelet or other means to be secured to one of the pins or hooks Q, so as to hold the member in proper operating position.

The bars M on the surface of the stationary members L, L, and L are arranged in a straight line with one another.

S is a traveling contact or block carrying a contact-sprin S, designed to come in contact with the ars M and also with one of the contact groups upon the movable members when said movable members are arranged in such a position that the contact roup will come in alinement with the path 0 travel of the contact-spring S. The block S is guided in its movements by the rails or tracks T, and thus it will be seen that by raising or lowering any of the contact members N any line of contact groups upon each of these movable members may be made to come into contact with the contact-spring S, and as each line of contacts upon these movable members represent a different numeral an combination ofnumbers can be made by t e proper masleeve W will slide upon the arm U and the block will be actuated between the rails T.

When the sender is to be operated, the arm is pulled toward the left-hand side of the instiument to the position as shown in Fig.2. Then as the arm is released the spring Vwill act to force the arm toward the right-hand side of the machine, and the contact-spring S will pass over the bars and contact groups in alinement with said bars.

To the binding-post Y is connected the terminal of the wire D. An electrical contact between said binding-post and the conducting-arm U is afforded by means of the switch-piece Y, adapted to bear with one end against one of the surfaces of the lower portion of the arm U. When the arm U is swung to the left-hand side, as illustrated in Fig. 2, the frictional engagement of the switch-piece Y with the lower surface of the arm will cause this switch-piece to follow the movement of this arm, thus throwing the lower portion out of contact with the terminal Y. Hence there is no electrical connection between said arm and said terminal during the period of movement of the arm in said direction; but upon the return movement of the bar the frictional engagement with the switch-piece Y will at once bring the lower part of said switch-piece into electrical contact with the binding-post Y and will maintain said contact during the whole period of movement of the arm U in that direction. It will thus be seen that when the arm U is in the first instance swung to the leit across the faces of the bars, dots, and dashes no circuit will be established; but on the re turn movement of said arm a circuit will be established with the wire D during the periods of contact between the contact-spring S and the bars, dots, and dashes then situ ated in the line which it traverses.

The bars, dots, and dashes having a predetermined significance, it is obvious that any signals within the range comprehended by the various groups upon the stationary as well as movable members can be transmitted and recorded. In the signal system the dots may stand. according to number, for the numerals 1, 2, 3, 4,and 5and the dashes for the numerals "6, 7, 8, "9, and 0.

As stated at the beginning of this specification, I have illustrated my invention as more particularly adapted for the use of signaling between railway-barns and their center. It is customary for the person in charge of starting the cars on their respective routes to signal the number of the car, the number of the conductor in charge of said car, and the number of the run or trip of said car to the superintendent at the central office. As an illustration, let us suppose that the large bar M designates the word car and the contact groups on each of the following movable members indicate one of the numerals 1, (l2, )7 ((3,7) ((4,7) ((5,)7 ((6177 ((7,!) (8,7) (9,77 O, and let us suppose that the first movable member adjacent to said stationary member is pulled downward, so that the group of contacts consisting of only one dash comes in alinement with said bar, as is illustrated in Fig. 2. Then it is obvious that the spring S in traveling over this bar and dash will indicate at the receiving-station that car No. 6 has just been sent out. The second stationary member is provided with two bars which may designate the word conductor, and therefore any of the numeral contact groups placed in alinement with said two bars will give the number of the conductor of said car when the spring S travels over the same. The third stationary member is provided with three bars, which may designate the word run or trip, and therefore any of the numeral contact groups placed in alinement with these three bars will give the number of the run or trip of said car when the contact spring S travels over the same.

To manipulate the movable members so that the proper numeral should come in alinement with the proper word or bar, it is only necessary to pull the member downward and secure the ring or other means on the hook having the desired numeral placed opposite thereto. The person who sends the message need therefore only have intelligence and skill sufficient to understand the numbers which correspond to the dots and dashes and the proper places to secure the respective contact groups. It will thus be seen that a telegraphic message comprising all the information within the necessary scope can be transmitted by a person who has no skill as a telegraph operator, since all that he has to do is to pull down the proper movable members and secure them in their respective places and then move the contact-arm across the proper region.

As stated before, the recording apparatus may be of any of the well-known types adapted to receive and record signals of the bars, dash, and dot character. Hence to avoid prolixity no detailed description of this element is given.

It is obvious that the different members, stationary as well as movable, have to be in electrical contactwith each other. So, also, is it obvious that the base-board may consist of an insulating material; but should the same consist of a conducting material the arm, as well as the switch-piece and binding-post, should be insulated therefrom. vious that the different members should not only be in electrical contact with each other, but should also be in electrical contact with the ground-wire G.
