It is found in practical telegraphy that, from variouseanses, messages can only be t'ransmitted a comparatively short distance before they must be treated as new messages, and retelegraphed to succeeding stations.

Mr. George B. Prescott, electrician of the Western Union Telegraph Company, in an article publishedintheJournalofthe Telegraph, under date of April 1,1870, page 107, entitled The Telegraph in Switzerland ,says, in speakingof telegraphic communication in the United States, that 'HMessages, therefore, instead of being' generally transmitted ve hundred and o ne thousand miles by one manipulation, arerepeated between the greater portion of the ofces upon an average of every 'one hundred miles. In most eases this repetition is made by hand, and every such repetition costs as much as the original transmission. For this reason long telegraph routes are necessarily made up of a surcession of short lines.

The antomatic-telegraph system in use atV the present time is based upon the transmission of messages bythe Morse characters, and, therefore, in sending a message over several of these successive lines, it must also be prepared anew by the operator at the end of each line before it can be automatically transmitted. This occasions great delay, for, While the actual transmission over the wire is exceedingly rapid as compared with the Morse system, the time consumed by the operators after receiving a transmitted message, in preparing it over again to he automatically transmitted, is proportionally very great.

My invention, in addition to the general improvement of the telegraphi'c art, has for its object to overcome this diiiculty, and automatically transmit a message overa succession of telegraph lines without the necessity for its repreparation at the end ot' each line, so that in sending a message it shall be automatically reproduced at the end ot' a line for automatic transmission over the next line,

thereby saving all the time and labor now re quired to telegraph by the automatic systems To this endmy invention consists, iirst, in; moi Zed mechanism consti? i .electric telegraph, and he following elements, to 'witzj iirst, an Instrument by which the written messages received at a station for transmission are recorded in a llet of paper to he used as the medium for automatically transmitting the message from one station to another, second, the batteries and insulated wires constituting the line or lines; third, a sending-instrument, adapted, in connection with `the record-fillet, to automatically transmit to the,I receiving-station message-signals corresponding to the record-signs of the iillet; fourth, a receiviiig-instrument adapted to receive sucht electric signals, and thereby automatically produce at the receiving-station `an exact fac-i simile of the original record-fillet at the send-` ing-station; and, lastly, mechanism adapted` to receive such reproduced record-fillet, andl therefrom automazically produce a dispatch for delivery, printed in ordinary typographie` characters. l

In the second place my invention consists Ain adapting different and independent telegraph-lines, and the instruments'used in con-l nection therewith, to operate in harmony with each other, so that either an original record-I tilletor a reproduced record-fillet ot' one line` can he used equally well to automatically operate anyother line. i

In the third place my invention consists in; the mode or process of automatically transmit-l tinga dispatch overa succession ot telegraphlines by the followingsteps, to wit: first, producing at the semling-station, by proper mechanism independent of the line, a record of the dispatch to be transmitted; second, automatically transmitting message signals or im-` )ulses' third 'automaticall reiroducinnr atl the receiving-station of a line, by proper mechanism, a fac-simile of the record at the sending-station; fourth, using, by suitable mech'- anism at the proper receiving-stations, the successively-reproduced records to automatically transmit the message overeach succeeding line until the nal or delivery station t is reached; and, fifth, using the reproduced record at the final station, by means of. proper mechanism independent ofthe line, to automatically print the message in ordinary typographie characters for delivery. y i

For the purpose of illnstratin g my improved system of telegraphing I have shown, upon Sheet l of the accompanying drawings, a' diagram ot' telegraph lines, routes, and stations, which, together with the followin planation, will afford a comprehensive view ot' the whole system.

In furtherance of this purposerit is necessary to define a teiegi route. y

A telegraph-line comprises the wires, batg general exapli-line anda telegraphyphia lille.

' teries, and instrumentsot two or more stations, wllich have such an electrical connection #with each other tllat an electrical ilnpulse routes, wllich'may be easily traced. For example, one line, with its way-stations, extends Ifrom Washington to Philadelphia; another from PhiladelphiaJ to New York; another from New York to New Londoll another from New Loudoll to Boston, and still another from Bostoll to Portland, the whole.number constituting one telegraph-route.

rlhe two endstations of a telegraph-line, whicll, inthe diagram, are marked A, and

whicll are connected by a wire, B, I designate as' the terminal stations, alld all those marked C, intervening between the terminal stations', and through which the wires pass directly, I denominate the way-oliices or intermediate stations.77 rIhe stations D, at which Itwo or more lilies are joined, l call the junctionfoflices',77 and those statiolls E, at which two or morev lilies cross or intersect each other,

l call the intersection-ofces. Certain olces may be junctiolroflices of `two lor more lines, alld thc way-offices of one or lnore lines-as,

lfor example, the New Haven ofh'ce showll on the diagram, which'is the junction-office of the Springfield and'New klavenline, thejullction-oiiice of the Binghamton and NewH-aven lille, and'the wa 7-oliice ot' the New York and New London line.- An office may also be the terlllillal oi' one lille alld the way-office of one or nlore other lines, asshown on the diagraln at Baltimore, whicllY is: the terminal' ofiice ot the Baltimore alld Wilkesbarre lille, and the way-office of the Washington alld Philadel- Harrisburg is also the Way-office ot' the Baltimore alld Wilkesbarre lille, alld the ternlinaloftice of the New York andklarrisburg lille. Similar offices are shown at Binghamton andl Springfield. Other arrange mellts ot' oflces may be found upoll the diagranl, and will readily suggest themselves as the occasion for their use arises.

rIheterminal stations ot' each telegraph-lille have the usual ground-connections F, and each station ot' a lille is provided with a local battel-y, Gr,.the object ot' ,which arrangement is to augment alld re-enforce the electric currents as they pass along the lille by the battery at eacll station.

In carrying outglny system I elllploy at each station ot' a telegraph-line one or more recording-instruments, a transnlitting-instrument, a reproducillg-illstrumellt, and one or more. printing-instruments, all of which I will presently describe in detail, ill the order All the instruments of a line are harmollizedwith each other, sov that the record of one station may be automatically reproduced ,in fac-simile at all the otllers, and the instruments of all the lilies constituting a route must be the same,.and operate in harmony Y with each other, ill order that either all origillal record-lillet ora reproduced record-llety of one line may be used to automatically op-l' erate any other lille ot' the rollte. rIhe junction-'offices of a route are provided with a set of instruments for each line, and the different sets have no electric connection with each other. Y

The record-illet, which constitutes the first step in kthe system, may have the messagemessages, designating furthe one that most lfrequently occurs the shortest slit, and ln- `creasing the length ot' the slits as the occur-` rence ot. the letters diminishes. The most frequentlyused sigll ill telegrams is the separatrix77 or space between words. 'This I lnake Y about one-halt' all inch ill length. rlhe order in which the letters of the alphabet most trequently occur is as follows, to wit: e t i a o s rnhdflcufmpbw y g Iv k m gj z. For these I lnake the slits increase in length. about one-sixteenth ot' all inch for each one, ill the above order. For example, the separatrix heilig one-halfen illcll long, the slit for the letter e is made nine-sixteentlls ot' al1 illch long; for the letter t, ten-sixteenths, alld so on. The sign for.linis, or the elld of amessage, should be one-sixteenth ot'an inch longer thall the sign forz, the last letter of -tlle alphabet.

These lengths and this order are not imperative, being used here principally to illustrate' the invention.

I will now proceed to describev the recordill g-instrument, referring tothe drawings conranged transversely or' the frame, with its bearillgs ill the bars G H., I Z are cams secured tothe inner elld ot' the lnaill shal't'with their shoulders upon opposite sides thereof, and O is a rock-snal't, having its bearillgs ill the sides ot' the frame, near the rear elld. 0 is a sleeve mounted loosely upon this shaft,

alld provided with a slotted arm, N, which is y connected'by a rod, M, to the-outer cam ot nection directly with the cam, it may, if found desirable, be formed by a crank arm on the end ol' the main shaft.

The rock-shaft O is further provided with a central tixed collar, carrying armsV T V at an angle to each other. The arm T is formed with a lateral lug, carrying a set-screw, tuto bear against a corresponding lug upon the arm N, while the arm V is connected with a vertical rack-bar, f, by the pivoted rod i, as shown in Fig. 3. S S are upright arms, firmly secured to the ends of the rockshaft, and jointed at their upper ends to the arms a"of a transverse stolrbar, c, whose'ends lie within longitudinal grooves formed in the side pieces of the case near thc upper edges. YV is a spring coiled about the rock-shaft, with one end secured to one ofthe arms S, and the opposite end to a collar, a', upon the sleeve 0. The. collar is adapted for adjustment upon the sleeve by a set-screw, y, .or other suitable means, to regulate the tension of the sprine. From the foregoing description it is evident that when power is applied to rotate the main shaft, the stop-bar will be moved back and forth within the grooves of the case, and that the rack-barf will be reciprocated vertically. The extent of this reciprocation is regulated by adjusting the end of the connecting-rod M within the slot of the arm N, while the path ofreciproca-tion is changed by adjusting the set-screw 'u to regulate the distance between the arms 'l and N. The tension ofthe spring is sufficiently strong to oscillate the rock-shaft and carry forward the stop-bar when the main shaft is rotated; butif the forward movement ofthe bar should be arrested before reaching its maximum throw, the tension of the spring will be overcome, so that the main shaft shall complete its rotation. E is a sleeve, mounted upon the main shaft, provided with a iiywheel, l), and a grooved pulley, C, to receive the. driving-belt of the instrument.

inasmuch as the power applied to the sleeve must drive it. continuously, and-inasmuch as it is absolutely necessary that the main shaft sha-ll rotate intermittingly, the sleeve `is adapted to grasp and rotate the shaft by fric' tion. For this purpose one-half ot' the sleeve is held tothe other halt' by set-screws and springs c, which may be adjusted to regulate the degree of friction, and thereforethe force with which the sleeve shall hold to the shaft. The sleeve is lined with leather or other pliable material, for the purpose ofequalizing the friction and preventing unequal wear. The force of the sleeve must be sufficiently great to overcome the tension ot' the coiled spring when the stop-bar is arrested in its forward movement, and at the same time slight enough to allow the sleeve to turn continuously when the shaft ceases to move. Some connection ot' this kind is required for the successful operation of the instrument, since the intermittent rotation ol' the main shaft must be repeated many times in a second. The keyboard of the instrument is composed of three banks of keys, divided into two sections,for the right and left hand of the operator, so that each bank of a section shall number five keys. rlhe section-dividing board z, together with the end boards y Iand front board a/l of thc case, forms guides for the fingers of the operator, so that he can look up to read a message while manipulating the keys. The boards y and z determine the stretch of the thumb and little finger, anmd so regulate the position of the intermediate fingers over the keys while guiding 'the hands in their backward and forward movements. The front boa-rd am' prevents the hands from going too far forward over the keys, and therefore forms afront guide at the upper bank. The keys are each pivoted upon a central pin, 11, afxed to a suitable crossfbar, A7. Their inner ends extend beneath the path of the stop-bar c, and are properly weighted, so as to rest, when not in operation, upon a rear cross-bar, 61, as shown in Fig.

As the signs which represent the letters of the alphabet and other message-symbols are formed by slits ot' differentlengths in the fillet of paper, and since the slittilig-instruments are operated by the rack-bar in a manner to be presently described, it follows, in this example of my invention, that the throw of the rackbar must be varied in proportion to the 'length of slits required. This is accomplished by suitable stops upon the upper edges ofthe keys to arrest the stop-bar at graduated distances in its forward movements. .The r'esult may be attained in a variety of ways; but in this instance I have shown the .keys formed with shoulders upon their upper edges at varying distances from their inner ends, such distances increasing from right to left of the keyboard, presenting the diagonal line shown in Fig. 2.

Since certain letters occur more frequently than others in telegraphic messages, which necessitates their representation byshort slits in the fillet of paper, I have transposed the alphabet and placed the letters in such order upon the shoulders of the keys that ,the stopbar will move the shortest `distance for the most frequently occurring letter, the length of its strokes being gra-dually increased in proportion to the decrease in the occurrence ot' the letters used. By this means the recording mechanism may, through the medium of the stop and rack bars, be operated with great rapidity within a given time. The letters of designation are duplicated in the same. order as the finger ends ofthe keys, as shown in Fig. 2. his a lever, hung upon a cross-shaft, 6, ofthe case, beneath the bar A7, and forked at its inner end to embrace the cams I Z on the main shaft, one arm,c', ot the fork bearing against t-he shoulder b ofthe cam l, and the other arm, m, at the proper time bearing against the periphery of the cam Z. The forked end of the lever should be sufficiently heavy to hold the arm 0 in contact with the shoulder b, and to return it rapidly against 1750.099' f s. j' "l 5 v suchl shoulder after having been lifted. KW

isa cross-bar arranged under and against the yforwa'rdportion of the keys, and connected to the endsand center of the shaft e' by arms f 'fand'theshort arm of the-forked lever.

As' above-described,,the powerv is `applied to Y drive lthe..friction-sleeve and By-wheel of the instrument"continuously; Vbut the rest of the mechanism is .motionless until the operator presses a key down u'pon the` cross-bar KU. VThismovem'entlifts the inner'eud of -the deteilt-lever, and releases the cam I, sothat ,the

friction-sleeve shall revolve the main-shaft,

y and, through the intermediate devices, throw forward the stop-bar untilit is arrested by the shoulder of t-he depressed key. The rack-bar,

- by thisoperat-ion, is .carried down inpropor'-,

tion .tothe distance-traveled by the stop-bar,

starting always from the same point-that is to say, it always starts downward from the same point, but descends differentially in pro- 'portion to the throw of the stop-bar.

' These'various parts constitute the mechanism for operating the recordingdevices, which is arranged transversely of the case, and may be pivoted -to the top of the spindle by a screwp'in, b5, as' shown in Fig 4. `A1 A1 are uprights of,the. i`rame, placed in line with the guide-bed to receive the feeding mechanism, by which the fillet of paper v'is 4drawn through the instrument.` pm is a spring connecting an a'rm',`o of the sleeve n" with an adjusting-pin, q", at the base of the outer upright,

' for the. purpose of holding the guide-bed in position with a yielding connection. r" .is a

Y stop attached to the case Within the path of the arm o, and adapted for adjustment to regulate the lateral swing of the guide-bed. By .this method of mounting and connecting the guide-bed itis automatically adjusted with delicacy and precision, to compensate for any irregularities in the running of thel paper, and to insure accuracy in its presentation to the recording-blades andfeeding-cylinder.' 0"

is an arm projecting to the rear ofthe guidebed sleeve n", and provided with a lateral pin, r, upon which the paper-reel q isihung. g is the paper, wound upon the 'reel beside a flange or rim,p, formed upon thelatter, and

thence passing upward, on its vway 'to thei guide-bed, through a guide-loop, fv, formed upon the upper end of a lever, 6. Theinner end ofthe paper is secured to the reel in any y convenient manner to prevent 'it from slipping. The lever carries a friction-brake, S", and is hung to the side of the arm Of, so that, under the force of.' a spring, w', it shall rpress the guide-loop away from the bed, and the brake down upon'the ange of the reel.

When thel instrument is in operation, the' feeding devices pull the paper over the feedbed with' slight, but rapid, jerks, which carry the guide-'loop'ulll toward the guide-bed, and lift the friction brake from the reel,lso that the latter. may turn and release 'the paper.- When the paper ceases' to move, thespring throws. out theupper end of the lever t", un-

'wviuding the paper from the reel until the frici tion-brake comes down'against the liange' thereof', and arrests its further rotation'.

t To increase thequantity ot' paper pulled othe reelin proportion to the 'increase in the,- -jl'en'gth of the ymessage-slits, it is passed over an intermediate guide, 00"", affixed' tothe end of the guide-bed, before passing over the guide '0'. After `leaving the reel-guides thev `papenrests upon the bottom ofthe guide-bed,

and is held against the adjustable outer or gage side Sll thereot1 by means ot' shoulders formed uponarms w x,\vhich are connected by a longitudinal bar, y, and slide `within deep transverse'grooves in the bottom ofthe bed, as shown in Fig. 2. The shoulders are heldfagainst; the fillet of paper, so that they shall conform to its varying width, by one or moresprings, 0', arranged to bear against theouter side of the bar y.

The pressure of the springs is adjusted by set-screws 6',passing through the inner side rail ofthe bed, or otherwise arranged in any otherconvenient manner, A pin,vm', iixed to the bottom of the guide-bed, limits the advance of the yielding shoulders when the il- Vlet of paper has passed outof the machine.

t is a cover or 'pressure-bar, hinged to the outerl edge of the guide-bed, so as to h'old 'downthe tll'etof paper, the amount of pressure or friction beingHregulated by the setscrew nV', Fig. l, upon which thefree edge of the cover rests. The' cover may be Weighted or held down by a spring, if preferred; but its own weight Will, inV most cases, probably be found 'sucient for all purposes. Its outer edge is formed with suitable recesses or spaces j, 10', and @"Qito` prevent the outer edgel ot' the paper from foldingA up as it passes over the guide.- bed and along the guide-*side S".

l is a handle affixed tothe cover, for opening and closing itin applying or removing the pa-per.
