Application filed July, 1886. Renewed July 23, 1888. Serial No. 280,826. No mode-ld fo all '1l/honra z'' 11mg collec/'717:

Bo it known that l', JOHN VNEIL, ot' the city, county, and State ot' NewYork, have 1 made certain new and useful Improvements in Automatic Multiplex rlelegraph Instruments; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relatesin general to improvements in telegraphy, and in particular to improvements in that branch of said art comi inonly known by the term automatic multii plex telegraphsg and it consists in the construction, arrangement, and combination ot parts, substantially as illustrated in the accompanying drawings, and hereinafter described.

Referring to the accompanying' drawings, in which similar letters of reference denote similar parts, Figure l represents a plan view of a transmitter and a receiver constructed in accordance with myinvention. Fig. 2 isa perspective view there 3f. Fig. 3 represents a diagram view of two stations provided with instruments constructed in accordance With my invention and connected by a single-line wire. Fig. 4 represents a detached detail vieu of the feed'mechanism. Fig. 5 is a sectional view taken through said feed mechanism on the line .a of Fig. 1. Fig. 6 is a sectional detail view showing another form of counteracting the etcct of the tailings Fig. '7 represents the contact-roller F, provided upon its opposite sides with feed-rollers. Fig. S represents the electro-magnet l?, connected to a permanent magnet. Fig. i) is a diagram view of tivo stations provided with instruments constructed and connected in accordance with my invention, showing the direction followed by oppositely-moving currents in full and dotted lilies, respectively. Fig. l0 is a detail view of a portion of its circuit-breaking Wheel M, showing' its relation to the switch-lever M.

ln the accom panying drawingsl have shown one embodiment oi' my invention transmitting and receiving instruments adapted to receive continuous strips or fillets of conductive or non-conductive paper or its substitute for the transmission and reception ot' messages, and l have so constructed, arranged, and connected said instruments with each other, thc main-line Wire, and the devices for throwing them into and out of circuit with 7 said line-wire, that said striijis oi' paper shall f be alternately and rapidly acted upon by currents ot eltisctrieity passiug'li'om and to said instruments, whereby a. message of one charaoter properly inscribed vupon one oi' said strips ot paper-that upon the transmittermay be automatically sent therefrom While a l message of different character is being rei ceived and inscribed on the paper upon the receiver. To these ends I secure the transmitter T and receiver R to a common base A, preferably made of wood, but which maybe made, it desired, of metal properly insulated from said instruments.

The transmitter and receivelfare in construction and operation very similar. I will therefore designate similar-parts in said instruments by the same letters, distinguished the one from the other by the use onthe receiver side of tsvo letters-as, for instance, d for a part of the transmitted-and c d for a similar part of the receiver.

B BB designate the paper-receiving spools, which are mo untcd upon. screw-threaded studs b bb, that project from posts h trl/ secured to the base, and are provided with tensionregulating nuts o2 hb2.

The paper strips C CC pass from said spools through guides 'formed near the upper ends of posts D DD. One of said post-s D is provided upon its top with a table formed of nonconductive matcria-lwas, for instance, vulcanite-to which is secured a metallic plate, d', the opposi te ends of which are provided with metallic binding-posts d2 and d3, that support a strip ot non-conductive material, d'ivhich extends from one to the other of the posts d2 and d3, and is provided Witlra binding-post, d, upon which the stylus-carrying arm or spring E of the transmitter is pivoted. The corresponding post, DD, ot the receiver is provided at its top above theA paper-guide D DX thereon with a binding-posa dd?, to which its stylus-arm EE is pivoted.

From the posts D DD the paper passes to and about metallic contact-rollers F FF, which are mounted in frames ffv 7*', hinged to contact-plates f ff", having binding-screws 2 ff2 and secured upon noncondnctive tables f3 jfs, held Within 1trames j" f7, fixed upon the tops ot posts fiff", that project from the hase A.

IOO

The rollers F FF and the paper strips thereon are held by springs f ff, (see Fig. 4,) pressed firmly against feed-rollers G GG, preferably formed of soft rubber, mounted upon shafts G GG', which have pointed o1' centered ends that are journaled within the recessed ends of screws g gg, which pass through the sides of the frames j ff.

g' gg designate ratchet-wheels, which are rigidly secured upon said shafts G GG. The teeth of said wheels are engaged by springpressed pawls g2 gg2, pivoted upon arms g3 gg', loosely hung upon the shafts G GG' and held from lateral movement thereon by collars g4 ggi. The arms g2' gg3 are connectedby rods g5 ggf with upwardly-projeet-ing rods or bars H HH, pivoted at their lower ends in bearings h hh, secured to the base A.

If desired, the contact-rollers may be provided at both sides with feed-rollers having rubber covering similar to that shown. (See Fig. 7.) The rods or bars H HH are vibrated back and forth to rotate the feed-wheels by the following' means, viz:

I II, designate armatures which are secured to said bars H HH near their lower ends and within the fields of electro-magnets I II', which are secured tothe posts f5 ff, whereby when said magnets are energized, as hereinafter described, the rods or bars Il HH and their connected pawl-arms g2 {jg/2 will be moved forward to rotate the ratchet-wheels and feedrolls of the shafts if G Willen said magnets are demagnetizerhthe rods or bars ll and HH and their attached armatures are drawn backward when the machine is not in use by springs t' Iii, which are connected at their opposite ends to said rods or bars and to tension-studs t" ii', that, project .from the base A. The back-and-forth movement ot' the bars H HH is limited by screws i2 z'z'f, that operate in studs i" lil, projecting from the base. .lamnuts if prevent said screws from turning when adjusted.

I prefer, for reasons hereinafter set forth, that the armatures I Il shall be operated in unison the one toward the other from its electro-magnet I' Il. 'lo this end l connect the'rods or bars ll lill together in any preferred manner as, for instance, that shown herein, which consists in a cord or wire, i2, that extends from one to the other of said bars.

K KK designate rods which project laterally from the bars Il l-IH, and are provided at their ends with binding-posts 7t- Mf, to which conducting-wires, hereinafter referred to, are connected. Said bars are cach preferably formed in two parts and connected together by an insulating-block, 71; and Mz. The styluscarrying arms or springs E EE extend to points immediately over the contact-rollers F FF, and are provided thereat with rolling electrodes E EE', which bear lightly upon the paper on said rollers, and are vibrated from side to side thereof by the following-d escribed means, viz:

E2 designates a bar of nonconductive material, which connects the arms or springs E EE together, and is provided at its center with an aperture to receive a bar or rod, L, that is pivoted at its lower end in proper manner in bearings Z, secured to the base A, and provided with an armature, L', placed within the iield of an electro-magnet, L2, secured to a post, Z, projecting from the base A. A spring, Z2, that extends from the bar L to a tension-post, Z3, operates to move the armature from the magnet when the latter is demagnetized. the bar L is limited by a screw, Z, that operates in a post, l5, secured to the base, and held stationary by an ordinary jam-nut. l

As will be hereinafter described, the currents from and to the transmitter and reeei ver pass successively through the electro-magnet L2 in opposite directions, thereby reversing the polarity of said magnet each time the transmitter or receiver is thrown into or out of circuit, whereby the armature L' is alternately and rapidly attracted and repelled by said magnet, thereby, through the rod L, imparting a rapid vibratory movement to the styluscarrying arms or springs E EE.

As will be readily understood, the tailings consequent in thev magnet L2 upon the stoppage of the current-iu one direction therethrough will operate to aid the current, which, as before stated, is im mediatel y passed through said magnet in direction opposite to the first.

'lhe transmitter T maybe thrown into and out of circuit by any desired'style of circuitbreaker, one form of which I have shown in the accompanying drawings, and which consists in a toothed wheel, lli, rotatably mounted upon a stud, n1, projecting from a standard, m', secured to the base A. vided with a handle, m2, and its teeth operate in connection with a tooth formed on a lever, M', pivoted to a stud, M2, that projects upward from a contact-plate, N, secured to the base A. The lever M is provided with a distance-screw, the end of which is normally held by a spring, in", in close contact with a stud, N', that projects from a contact-plate, N2, secured to the base. Y

O designates a contact-plate, to one end of which is secured a binding-post, O', to which the main-line battery-wire is secured in the ordinary manner. y

O2 designates a switch pivoted to the opposite end of said plate O to establish circuit between said plate and the plate N2.

P designates a contact-plate secured to the base. A, and provided at one end with a binding-post, P', to which is secured, in the usual manner, a short section of conductive material, p, to serve a purpose hereinafter described. To the opposite end of the plate P is pivoted a switch, P2, which is adapted to be placed in Contact with either of the contact-plates N or N2, to throw the lever M into or out of circuit,

The back-and-forth movement ofl This wheel is pro- IOO ITO

As will be observed, the magnets l Il are interposed in the main-line circuit-s of the transmitter and receiver, respectively, and that consequently the currents to and from said main 'line will pass through said magnets either before or after passing through the paper upon said instruments, the different directions of which current necessitates different arrangements ot the conducting-wires to and through said instruments to said main line. To clearly show said different arrangements of the wires lf have illustrated the iirstto wit, that in which the current rst passes through the electro-magnet-by altern ate dash and dot lines, and the latter-to wit, that in' which the current irst passes through the paper-by dotted lines, and will hereinafter trace the course of the currents through the instruments to main line from and to the main-line battery and ground. y

It will also be understood that the message impulses ltrom the main-line battery are designed to operate electro-magnets I and Il ot' the feed mechanism, whereby the construction and operation of my improvement are greatly simplied. If desired, however, said electro-maguets may be operated by a local battery, the magnet L3 bei ug alone interposed in the main-line circuit.

- l preferably employ non-conductive transi mitling-strips or-lillets of paper inscribing" the message to be sent thereon in conduct-ive t t, cuit therefrom to the receiver.

ink or with a sot'tlead-pencil, the metallic elements oi' which latter when tforced into the paper form a good conductive medium from the stylus to the condnoting-roller below; or

said transmitting-strips may be composed ot l suitable conductive material, in which case .t

non-conductivc inl( is used to write the me sitge thereon. ,lhe receiving strip or Fillet is impregnated or coated with any desired solui tion which is adapted to be readily decomposed b v electrolysis.

The operation ot my device is as follows: ,-issiuning the instruments at one station to be in proper working order, the transmitter having its strip otf paperinscribed with-a message to be sent, the receiver provided with receiving-strips ot' proper tpiality, and both in connection with similarly constructml and= equipped instruments at a distant station to and from which messages are to besent and received, l will tirst trace the current through the course indicated by dotted lines, in which it will be remembered said current passes From the post kk the current kpasses to and through the magnet L2, energizing said magnet, and thereby vibrating the stylus-carrying arms toward the receiver side of the instrument. From the magnet L2 the current passes to the insulated post. 7s, which, inasmuch as the armature-carryingbars H and HH of the magnets l and ll are positively connected together, as hereinbetore described, is now in Contact with the binding-post l. Thence the current passes to the bindingpost (Z5 of the arm E, thence through said arm and its stylus to and through the paper strip C to the contact-roller F, thence through the frame f to post f2, thence to abinding-post, 2, secured to the basel, A, thence to and through the electro-magi] et l to l'iinding-post, and by line -iO to the main line UL. The magnet I is energized bythe passage of the current, whereby its armature I and the bar H, to which the armature is attached, are drawn for-` ward, which movement, through the connecting-bar g5, arm gi", pawl a-nd ratchet wheel g2 and g', operates the feed-roll G to move the paper strip forward. Said movement of the bar H, also through the connection i?, draws the armature H of the receiver away from its magnet- H, and at the same time moves the insulated posts 7.1 and M.: away 'from posts P and l, and into contact with posts l and 5, thereby breaking the circuit through the transmitter to main line and closing the cir- 1When the circuit is so closed, the current from the distant station passes by line tlirom the main line to post l, thence to insulated post fr, and then ce to and through the magnet L2, changing the polarityY of said magnet?, thereby causing it to first repel and then attrait-t its armature, and therelrv, through the har L, to vibrate the stylus-carrying arms E Elfi, From the magnet- LL the current passes to insulated post Llc, thence to post 5, with which it is now in contact, thence to the binding-post (M5 of arm EE, thence through said arm, its attached. stylus, and the re eiving-strip CC to contactroller Fl? and its framejf'3 to postjf, thence to post t?, thence, as shown by line 42 in Figs. i) and .l, to and through the electro-magnet Il', and thence to post '7 and earth. The magnet Il is energized by the passage of the current,

through the paper to the Feed-magnets. b'tarting, TF designates the earth, and MB the mainline battery, from which the current passes to the binding-post O', thence through the plate O and switch O2 to plate N2, from which it passes either directly or through the circuitg breakin g lever ill' to the switch P2 and post P', thence through conductor 'p to the binding-post ff, which, it will be remembered, is insulated from its actuating -magnet, and which is drawn by the hand when starting current into contact with the conductor p.

and through the consequent torn-'ard movement of its armature moves the feed-rollerof the receiver forward, draws the armature I of the transmitter from its magnet I', and returns the insulated posts k and 107tinto contact with the posts P and l, thereby throwing the receiver out of and-the transmitter into circuit with the main line. The circuit through the transmitiling-instrument may be either continuously interrupted or wholly broken through the medium of the circuitbreaking wheel lll or the switches p2 or O2, when necessary, the former of said operations heilig :facilitated by the serrated periphery of the wheel and the relation of said wheel to the pivoted switch or lever M', the distance IIC or .contact screw in the end of which latter is alternately moved into and out of contact with the stud N by the rotation of the wheel, as will be readily apparent. If desired, the circuit may be wholly broken by bringing one of the teeth of the wheel M to rest upon the upper end of the spur of the lever M', thereby elevating' the free end of said lever from the stud N', as well as by moving the 1o switch P2 out of contact with the plates N or N2..

From the foregoing the operationand purpose of the circuit-breaking wheel will be understood Without further description. l

S0 far as described, it will be apparent that no provision has been made either in the construction or arrangement of the mechanism or conductor comprised in my invent-ion to counteract the effect upon the strips or fillets 2o C and CC of the tailings consequent upon the demagnetizing of the electro-magnets I II, which, as has been shown, are interposed in the main-line circuits of the transmitter and receiver respectively. To fully protect 2 5 said strips from damage by said tailings, I provide each of the stylus-carrying arms E and EE with devices thatshall operate to positively raise said arms out of contact with said strips C and CC at the moment the magnet in the circuit with said arm is demagnetized, and I also arrange the conductors in such manner that the current shall pass through said magnets before passing through said strips. To these ends R RR designate 3 5 props, hinged to the supports upon which the arms E and EE are mounted below the same and connected by arms S SS with the feed-pawl arms gi and gg of the transmitter and receiver, respectively. Then the bars 4o H HH are moved backward, said props will move in unisonr therewith and will operate to raise said arms, will be understood. hen this construction ot' parts is employed,

...-fI preferably arrange the eondncting-wires 'F45 so that the course followed by the currents is as follows: Starting at post P', the current passes to in: ulated post 711k, and thence through magnet L2 ,to insulated post 7c, as hereinbefore set forth. From said post the 5o current passes to post l, thence, as shown by line 44,'Fig. 2, to and through the magnet I (see dash and dot lines) to the binding-post of stylus-holding arm E, thence through said arm, its stylus, and strip C to the contact- 5 5 roller F, thence through frame` f to post f2, thence to post 3 and main line, the return current passing from post et through insulated post la, magnet L2, and insulated post kk, to post 5, in manner hereinbefore described. 6o The current passes from post 5 to and through electro -maguet II to post ddi of arm EE', thence through said arm, its stylus, and the paper CC to contact-roller FF, and thence to post 6 and earth, as shown by dash and dotlines.

By this described construction and arrangement of parts I am enabled to throw each magnet I or IIl entirely out of circuit with the main line, and also through the medium of the props R with the arms E EE, thereby effectually guarding against damage to the paper strip from reflex currents from said A manent magnet.

It will be observed that the strips C and CC are moved forward in step-by-step motion by the described devices for operating the feedrollers thereof.

If desired, the feed mechanism of both transmitter and.v receiver may be located at the same end of the base A, the stylus-carrying arms thereof being arranged to move in the same or in contrary directions. The conducting-wires from the binding-posts 1 and 5 may connect with thebottom of the posts L or D and DD, as shown at 48 in Fig. 2, when the wires are arranged in this manner. I provide that reiiex or induced currents from the several magnets comprised in my invention may be counteracted in the event of the mechanism for that purpose, hereinbefore described, becoming inoperative by the following means, viz: G, Fig. G, designates a rubber ring, which is placed upon the bind-ingposts di and c1615 of the arms E and EE, as shown, or with the posts D and DD, and holds in position a metallic (preferably copper) ring, 7, which is connected by a wire, 8, with a ground-plate, 9, by which induced currents passing through the posts inthe direction or eontrariwise of the arrow 10 will be counteracted, as will be readily understood.

If desired, the mechanism above described may be used in connection with the prop R and its actuating-rod, hereinbefore described.

l To insure that the strip or fillet may have the proper degree of moisture, I provide a fluid-receptacle, 13, (see Fig. 4,) securing the same to the plates fSffS in advance of the metallic rollers F FF, and placed within said receptacles rollers 14 and 15, the lower, 14, of which is preferably made of vulcanite and operates as a brush to dampen the paper llet- The other, 15, is preferably made of metal, and operates as a press-roll to remove superifiuous fluid from said strip in its forward passage between said rollers, for which reason I employ springs 16 to connect the bearings of said rollers, as shown.

Any desired form of battery may be employed in connection with. the devices shown and described.
