IMPROVEMENT IN PRlNTlNG-TELEGRAPHS.

Specification forming part of Letters Patent No. 136,369, dated March 4, 1873.

To all whom it may concern:

Be it known that I, MERRITT GALLY, of Rochester, in the county of Monroe and State of New York, have made a new and useful invention pertaining to the Art of Telegraphy and I do hereby declare that the following is afull and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon.

The object of myinvention is, first, to shorten the process of telegraphing, and thus reduce the labor ot'the opera-tor and increase the speed of operation secondly, to secure nicelyprinte'd telegrams by the use of simple and durable instruments. My invention consists, first, in a new and useful unison device; sec ondly, in the use ot'single keys, each representin g a number of separate letters or characters, to be brought into use by a single stroke of the key thirdly, in the use of a conducting-pile, forming a new and useful repeating circuitcloser; fourthly, in the use ofa pulsating device in connection with the main line, for governing a'number of transmitting or receiving instruments, the transmitting impulses of the transmitters occupying the intervals between the pulsations of the governor; fifthly, in the combination of more than two operating instruments with a single telegraphic line, simultaneously employed without conflict of their messages; sixthly,'in the useof a type-wheel with a reciprocating journal-bearing; seventhl y, in the use ofa paper-holdin g cylinder, having its line of printing around its circumference, and a longitudinal movement for placing the position of the lines; eighthly, in the use of a paper-holdin g cylinder, containing, internally, the paper to be supplied to the outside; ninthly, in the combination of anumber ot' paper-holders, together with a motor, which brings one after the other into printing position, so that the printing of the instrument may be continued upon one while the message is being removed from another; tentl1ly,in making the type-wheels of two or more instruments on a telegraphic line to differ relatively in position as respects the material impressed, so that the electric impulse causing the impression of a letter in one instrument will not cause the other to print, but that the printing may be carried on in'the difierentinstruments by means of different impulses; eleventhly, in the connection, with a telegraphic instrument or type writer, ofau independent form with headingor other frequently-recurring portion of the work to beimpressed upon the printed materialwhen required; twelfthly, in the use of a paper-creaser or markerin connection with atelegraphic in} strument or type-writer; thirteenthly, in the combination, with a printing-telegraph instrument, of a sounding device, which may be op erated simultaneously with thcprintingdevice; fourteenthly, in a type-wheel having a number of ciphers, which may be used singly or in numbers during a single revolution of the typewheel; fifteenthly, in the use of an adjustable circuit-closer.

General Description.

I am aware that pendulums having simply a vibratory movement have been used in connection with telegraphic. instruments with an attempt to secure unison thereby, but they have been comparatively inoperative, especially where very rapid pulsations have been required. In their results they have been deficient 'formany reasons, prominent, among which are the facts that their vibrations have been comparativelyslow, and their speed different in different portions of their are of v1- bration. The latter of these defects IpartiaL ly overcame by constructing upon the are a number of conducting-faces varying in distance from each other in proportion to the variation of movement; and, when necessary, varying also in breadth of face; butthe results not being fully satisfactoryI brought; into use the revolving-pendulum. The movement of such a pendulum remains equal in speed at all points in the circle of its motion. On such a circle a great number of conducting-surfaces may be placed; and, as the pendulum can be revolved very rapidly, great ac curacy can be attainedin producing ra pid-timed impulses.

1n the machine represented in the drawing I use the revolving pendulum in connection with a conducting-pile ot' peculiar construction, although it may be used with good results i non-comlucting sections. Within the pile is a solidi-lug, F. This ring may have an entire coiulucting-face, but to avoid any possibility, of mixingimpulses it is divided into as many conducting and non-conducting faces and intervals as theupper plate of the pile. Connected with the conducting-pile described is' another pile of conducting-plates of equal number, represented by H. With this pile of plates the operating-keys make the circuitconnections; therefore, the plates must equal in number the characters of the type-wheel,

and these plates must connect with as many rin of the first-described pile, and as many conducting-bars, K, must each connect with one of the conducting-sections of the upper plate the coinlucting-pile. There may be a greater number of the conducting-sections, as wid be hereinafter explained, for the purpose of adjustment. Upon the shaft 0, which revolves with the penduluinA, is a metallic circuit-connector,.D. The gear of shaft 0 may connect with the type-wheel where any Y two instruments are keptin unison by the device describethand in such case no escapement will be required; but a greater number may be kept in unison by the attachmentof the revolving pendulum, if desired, without an escapement. For example, let a number of print-ing-instruments having the revolving pendnlums attached be connected. to a telegraphic line. Let a key, representing a particular letter. of the type-wheels, .be agreed 1 upon, by whit-h the several machines areto be tested as to imp. 1 previously, the key'willclose the circuit with Now, as we have said the instrument at one of its-divisions by connecting the circuit-wire with one of the plates of pile H. As there is also another division of the circuit between the circular con-- the internal ring with a conducting-face of the circular pile corresponding with the plate of pile H which has been made to connect with the circuit-wire by the working of thekey.

The internal ring of the circular pile is attatched to the circuit-wire, which is shown in Fig. 1. The other parts of the circuit-wire connecting with the pivot of the connector in Fig. 12, the ends of both parts of the wire mentioned forming a connection with the main line, completes the circuit. Now, it the pendulums ot'the several instruments be set in motion, and the standard key of each instrument be depressed, it only a single impulse passes through the circuit at each revolution of the pendulum, the se eral instruments will be in unison; butif no rmpulse passes, or a number at each revolution of the pendulum, the instruments will not be in unison. To adjust the instruments to unison the circular pile is made to turn upon its axis by means of the handle N. This will afl'ect only the positions of the comlucting-faces of the circular pilein respect to the revolving circuit-connector without attecting the relation of the plates of pile H and the conducting-surfaces of thecircular pile, because the rings of the circular pile form at their circumference a continuous unchangeable connection with the corresponding plates of pile H.

To increase the speed of operation, I use single keys representing a number of separate letters of the type-wheel, which may be'printed during a single revolution of the typewheel and by a single stroke of the key. This is accomplished by making the key circuitconnector of such keys connect with a number of the plates of pile H, corresponding with an equal number of the letters of the type-wheel in passing once around its circumference, or following each other in a number of very rapid revolutions. 1n the latter case with more than one revolution ofthe wheel only the manipulating process would be'shortened. In order to secure the desired result with a single revolution of the type-wheel, and to securea large number of such keys representing many frequently-recurring words, syllables, and combinations, I first arrange the letters of' the type-wheel out of an alphabetic order, and in such a way as to be able to spell as many words, syllables, and combinations with the letters while passing in one direction around the type-wheel. the manipulation of the keys I place them in classified groups. The key movement is, in most respects, similar to that described'in my patent of July, 187 2, N 0. 129,725. I will there fore state only'the manner of connecting it with the instruments herein'described. The key J 'of Fig. 12 represents. one of the keys of the key-board, Fig. 11. The number of circuit-closers H is equal to the number of keys of the keyboard, Fig. 11. The circuit-- In order to further facilitate closers H form as many connections, or, in other words, conneotwith as many of the plates of pile H as they each represent letters upon the type-wheel. The narrow edge of the circuit-closer of each closer is driven forward by its key to connect with projecting points from as many of the plates as are re quired to produce the print of the number of letters represented by the key. The key J, Fig. 12, operates upon three such points by means of its connector, this key representing three letters, which spell the word his. Other keys representing other frequently-recurring words are arranged in similar manner, connecting with their respective plates. The pile of plates represented in Fig. 12, as H, is a cross-sectional view, and is the pile H of Fig. 1. The electric impulses which are passed through the circuit are conveyed to the electro-magnet :v and brl hg down the lever of the armature V. The type-wheel P is hung in reciprocating jonrnal'bearings T, which are acted upon by the lever of the armature, bringing the type-wheeldown in connection with the paper as the impulses pass the circuit.

The escapement-wheel P is not necessary to the action of the instruments as thus far described, as the typewheels are revolved and kept in unison by means of their revolving pendulums and motors.

In order to secure sufficient time for the operator to depress a key and secure his connections,'I make the returning-shifter m, Fig. 12, which returns the bars H to place, in two parts-one part to act upon the bars of the keys which indicate the numerals and the other part upon the bars representing the letters. As the letters and numerals are in separate groups on the face of the type-wheel the keys of the letters may be depressed during the time in which the numerals are passing a given point, and the keys of the numerals may be depressed while the letters are passing a given point. The cam-wheel B revolves horizontally under the latch-lever m and lifts it, relieving the shifter and allowing the depression of the keys connecting with the shifter while the lifting-cam m is passing under the lever-latchv m. The lifting-cam occupies that portion of the circumferenceof the cam-wheel which corresponds to the part of the face of the type-wheel occupied by the letters or numerals, as the case may be. The cam-wheel revolves atequal speed with the type-wheel. Thus it will be seen that two cams will be necessary, and also two leverlatches connecting with the shifters of their respective set of keys.

Havingconstructed the transmitting-instruments so as to secure speed and facility of operation, the next part of my invention has reference to increasing the transmitting capacity of the line. Duplicate instruments have already been employed simultaneously upon a single telegraphic line, but such alimited increase of capacity does not answer the demand; and I have therefore constructed my instruments with a view to the employment of more than two, simultaneously, upon a single line. For this purpose I leave suiticient space between the letters of the typewheels to allow a number of impulses to pass through the magnet and depress the typewheel during its movement without making impressions upon the paper. I set the typewheels ofseveral instruments on the line in such relative position, in respect to their printed material as to secure to each the printing depression by a different impulse from those causing the printing of the other type-wheels. I set the circular pile of each instrument to correspond with the relative position of its type-wheel and paper; and the number ofinstnnnents are pre pared for use. If each instrumentis provided with its revolving pendulum,'and the several pendulums are revolving in unison, it will be seen that all the instruments may he simultaneously employed, printing successively by succeeding impulses, and that no impulses will .be necessary to pass the circuit, except one for each printed letter. If, however, it is desirable to do away with the use of so many revolving pendulums, I remove them from the instruments and employ but one, with an independent battery connected with. the lnain line. .It is not necessary that this should be a strictly time-keeping instrument, but any rapid pulsator with a comparatively steady movement may be employed. I, however,'use

the revolving pendulum as the best means of producing a regular and rapid pulsator. In order to employ anumber of instruments simultaneously with this arrangement of devices I must usethe escapement-wheel P,Fig. 6. Al

though the revolving pendulums are removed from the transmittin g or receiving instruments, the circular piles and revolving circuit-closer are retained, together with the motor. I set the relative printing positions of the typewheels of the several instruments as in the previous case. -I make the conducting faces of the pile connected with the revolving pendulum of the main line to differ from those of the piles of the instruments as to relative position,-

making them to correspond with the non-conducting intervals of the instrument-piles. I

make the teeth of the escapementiwheel P to enough upon-the escapement toinsure unison to the movements of the several wheels.

I set the pulsator of the main linein motion,

and all the wheels of the'difi'erent instruments are allowed to revolve; and as to their speed, are kept in unison by means of the pulsations of the main battery through the main line. Now, as the impulses caused by workin g the keys of the transmitters can occur only between the impulses from the main-line pulsator, it is apparent that all the several instrn ments ma'y be employed on a single line without conflict of their several messages.

4 V is 6,369

In diagram, Fig. 5, the smaller white spaces represent the conductors of the line-pulsator, and the larger white spaces the conductors of t e instrument-pile.

In order to be able to read by ear the message which is being printed, or while a printing-transmitter is at work upon the line, I attach to the instrument an additional circular pile and divide the larger conductors, represented by the larger white spaces of the diagram, into the dots and dashes representing the several letters. I make the conducting-bar for each letter connect with the number of dots and dashes. I then attach a sounder to the pile, and the message beingcommunicated may be read byear, whether any of the instruments are printing or not.

The paper upon which the message is to be priiited I place upon the cylinder Q, which turns with the type-wheel at such times as the types are in contact with the paper. The line of printing is thus formed around the cylinder. When a line is completed the cylinder is suddenly moved the space of a line by means of a small spur, a which passes through one of the diagonal grooves of the grooved piece Y. The next line of printing is immediately begun, and so on until the face of the cylinderhas been printed over.

In order that the printing may still go on uninterruptedly, I use two or more cylinders, two being represented in the drawing. The journal-hearin gs ofthese cylinders are attached to a head-piece, B which may be made to turn on an axis, inverting the positions of the cylinders. A common clutch-rod, Fig. 9, is used to connectthe head B with the stationary frame-work. When the spur a, which produces the longitudinal movement of the cylinder upon which the printing is being done passes through the last diagonal groove of the grooved piece Y it comes in contact with the cross-piece a of the cl utchrod and relieves the clutch. The weighted cord N upon the pulley N of the journal of the head B instantly inverts the positions of the cylinders, and the printing goes on upon the newly-placed cylinder without interruption while the printed page is being removed from the first cylinder.

To keep the cylinders constantly supplied with paper I make them hollow, and upon the internal spindle I place a roll of paper, S, Fig. 6, the end of the paper being passed through an opening in the side of the cylinder, and, having been passed around its circumference, is clamped by a spring-clamp, a.

To remove the printed paper it is only necessary the draw out the paper, unwinding the roll, and tearing ott' the printed part. This leaves the cylinder freshly covered. By clamping both ends of a sheet which simply covers the cylinder single sheets may be used instead of the roll.

The paper, used either in rolls or sheets, may have upon it the usual printed headings, he; but for printing headings or frequentlyrecurring portions of the work I attach to the instrument a form-wheel, m, which is upon a rocking bearing,-and may be brought into. contact with the paper upon one of the cylinders by lifting the levern. Ink having beenapplied to the form-wheel, a single turn by means of its crank will make the impression of the form upon the paper. Two markingspurs, g g, are shown projecting from the piece h, which .may be also brought into contactwith the paper while the cylinder is revolving, and thus crease or mark the paper to facilitate folding. Small wheels instead of spurs may be used. By examining the operating-key movement of former patent referred to it will bese'en that, by combining such key-movement with the transmitting instruments herein described, a number of keys representing difi'erent letters may be struck simultaneously by a simple stroke, and without holding the keys the several letters will be transmitted in their proper order, as the keys are brought back to place only after the proper work has been accomplished by each. This enables an operator to select a second combination of keys and have his fingers placed in readiness to strike them while the first set struck, are accomplishing their work, thus greatly facilitating the operation of the instrument. In the arrangement of the key-board, as shown in Fig. 11, no duplication of letters is necessary 011 the type-wheel except the oftenrecurring double letters E and L. An 0 might be advantageously added. For the numerals I place three ciphers upon the wheel. This allows me to make numbers with tens, hundreds, or thousands, at a single stroke.
