Specification of Letters Patent. I Appii'eation mea February 9,

To all 'whom it may concern.'

Be it known that l, J oiiAN J. Vninuiiinz, a. subject of the Queen of the Netherlands, residing at Oakland, in the county ot Ala ineda and State ot California, have invented Telegaphs, of which specification.

My invention relates to telegraphic transmit-ters, and pertains especially to a print ing telegraph adapted to he used on any system including the common single line closed circuit system, employing al type- Writing keyboard at the sending end and a type-printii'ig or equivalent arrangement at the receiving end ,for recording the messages, impulses, or other signals sent.

the following is a them, as shown in Figs. 2 and 3. The coniinutator segments LSL-8', Fig. l, are the sending' segments, and the cominutator segments )9 are the receiving segments.

The receiving segment 9 Vof the Sending machine is divided otf into seven independent, insulated and electrically conductive portions a, l), c, il, c, f and g; the end pory The invention consists of the arrangement tions c and g being separated from Ythe of parts and the details ot construction others by the Wider insulatit'ins 10, and the `o1' receive at either Aleft hand side of the drawing, and the rel station, and l at the iecoiriiig` st ation. Fach of these pendulunis is suitably mounted tor` intermediate portions l), c, etc., oi the corninutator, by the thinner insulating strips l1. Similarly with the receiving segment 9 of the receiving machine. (It is to be understood that the so-calleil receiving segment of the sending machine is inoperative as to secztions'lnc, (1,6, and f, and only operative as to the end sections a and y when sending messages, as will inore clearly appear later.v The saine is true of the sending segment of the rcccixing machine when the latter is. receiving messages.) The complementary sending segment 8 ot the sending machine is also divided into seven electrically conditi. tive portions n, 0, y?, g, i", s and i, but the parts 0, p, q, fr and s are relatively much narrower than the coni'luctive parts Zi, e, al, e aiidot the segment t); each section o, y), etc., being insulated 'from the others by an intermediate body of suitable insulatingmaterial, like hard rubber.

The conducting sections 0, QJ, gl, i", s oi the sending segment 8 stand .in radial planes ap1 proxiinately midway oit the conducting sections l), c, (l, c, f of the receiving segment 9, and. usually these sections o, y?, g, r, s are only about one-'tenth of the .Width of the opposed conducting sections l), c, cl, e, f on segment 9. It is understood that the saine division occurs 'with the segments 8-9 of the receiving machine.

The end sections c, segments 8-9 are simply which which will he more 'fully explained by reference to the accompanying drawing in which# n Figure l is a diagrammatic view, showing the sending and receiving mechanisms and circuits. Fig.. is a` side elevation of the enduluin mechanism. Fig. f5 is a plan view of the same. F flis a longitudinal sec tion showing the printing mechanism and connective parts. Fig. 5 a plan section, on l-ine X-X, Fig. kt. F (3 is a. perspective View of a comb magnet latch. Fig. 7 is a plan section showing the circuit closing mechanism llt). Fig. o is a similar view showing the circuit closii'ig' mechanism 40e-4l. A Referring to Fig. l, it will be understood that the apparatus is adapted to send itron'r end oi the line, and a. description of the sending mar-.linie will answer in great part for a` description of the receiving machine. In the present case lf shall simply describe,'aiid cliiciiy illustrate, the sending from one end and the receiving at the other.

In the diag anima sending ii'icchanisin is represented lic view ot Fig. '1, the at theceiving met-.lianisiii at the right. l

Each machine employs a` pendului'n ineinber which is represented at it at the sending g, and. n, zfot the oscillation, and they carry respective armafor the purpose ot by side, with the pendulum Working' between sending plished 'the ground, to return.

vg, whereupon another. circuit is to send the cl'iaracter,

and for holding and at the end of its stroke; the sending of all the characters over the line being accomplished through the closing of certain circuits as the brush 6 passes over one or the other of the thin metal strips o, p, g, z', s, and the brush 7 of the receiving machine passes. over similar' wide metallic sections 7J', c', d', e', f, of its segment 9', as will be explained later.

By means of the segments divided as here shown, I am` able to transmit over a single main line all the letters of the alphabet, numerals and symbols usual or necessary in the transmission of messages. 'I

The manner'of effecting the various selections to produce the desired results in the and receiving machines is accomfollows; 20, Fig. l, represents the'main line of an ordinary single line closed circuit system having the gravity batteriesv or equivalent 21-21 at each end of the line and connecting ground wires. The battery 21 has one terminal connected with the armature 22 of the transmitter 23. 22 is one member of 'a switch, of which the other member is 24, which latter connects with the local relay 25, then with the main line 20; through the armature 22 of the' receiving machine to relay 25, and through the battery 2l with Springs 22a-22h hold switches 22-24, 2,2-24 normally closed, so I 4have a normally closed main line circuit with the two relays 25-25 in series.

The end section a of the segment 9 is connected by wire 34 with the magnet 35 which controls the armature switch member 35a; the other terminal of the lower switch magnet 35 is connected by a wire 36 with the pendulum magnet 3; the other terminal of magnet 3 is connected withA the opposite pendulum magnet 4; the two magnets 3-4 being in series, and the other ter'- minal 'of magnet 4 is connected by wire 38 with a contact point 39, which latter is normally in contact with the armature 25il of the relay 25. Then the line is closed, as

hown, a circuit will be made through the" armature 25a of the local relay, through wires 30 and 3l to the main local battery 28; thence through wire 29 to pendulum A, and by brush 7 to section a of the segment 9 whenever the. pendulum is swung to its limit in that direction. A circuit is thus completed to energize the pendulum magnets 3 4 and hold the pendulum to one side. .Breakinor the circuit denergizesl magnets 3-4, allowing pendulum A t-o swing by gravity and bring brush 7 over the section similarly established through the magnets and wire ,is employed,

by a system of electrical wiring, aster 225; the other `and 8, as described later.

' turn controls 53, magnet 35, armature 25, wires S50- 31, local battery 28, wire 29 and pendulum ,.Lvthus aga-in hold- 'ng the pendulum Each time a sending key 2G is depressed, this action of breaking' an restablishing a circuit takes place.

Since a normally closed main line circuit the circuit through magnets 8-4 will be' closed that the armature 2 will be attracted in the manner shown, and cause the pendulum to stand and remain, at an angle with thebrushes 6-7 resting on their correspondingsegments 8 9V and sections (i-n so long as the circuit is unbroken. The breaking of this normally closed circuit is accomplished by the depression of a key `26 on the keyboard.

The key 26 is electrically connected by a wire 27. with one terminal of this transmitter is connected with the main local battery 28 by wir@I 3l, and the other terminal of wires StB-38, contact 89,

terminal of the transmitbattery 2S is electrically connected by a wire 29 with the pendulum A, as before When the sending key 26 is .standing normally in the up position shown in Fig. l, it will close two contacts 40 and 4l, Figs. -l-

A wire 42 connects the contact member 40 witha local-battery 43, and a wire 44 connects the other terminal of the battery with the armature 35a of the magnets 235 35b. This armature 35a cooperates with one or the other of a pair of contacts 45 or 46 to close a circuit leading to on'e or the other magnets 48-481, which latter control an armature 49. The other terminals of the magnets 48`48a are connected by wire 50 back to the contact member 4l. Thus a secondary local circuit is normally closed through battery 43, and the purpose of this local circuit is to prepare another circuit through the transmitter 23,-this latter Vcircuit when closed energizing the transmitter and denergizing the pendulum magnets, allowing the pendulums to swing. This is done as follows: A switch 52 on wire 42 is closed, as shown, when the machine is sending. 'Armature 49 `swings between a pair of contacts 55456. Contact 55 is connected by a wire 58 to section a -of sending segment 8, and'contact 56 is connected by a wire 57 with the opposite, end section t. It will thus be seen that theI function off the switch magnets S35-$5 is to throw the switch member 35a from one contact 45 to the other 46, and Vice Versa; that this again completes,the` circuit for one or the other of the switch magnets 48-48A which in the movement of the armature switch member 49. The armature 49 is connected. by a wire 62 with a spring Contact member 61 arranged ito be'brought i'hrougl'l the lin-nah (i, pendulunfil;Wire 29, hatscribe.

. g, r, s, in the sending machine, and the sections L', c', d", e', f', 1n the receiving machine: i

v contacts.

These combinations, exceptthefirst (0),

I i are utilized through themedium of one or more contacts placed between the contact member 61 and the corresponding key 2.6. For instance, by referring to I ig. 1, I haveA shown two contacts 59-60 which in this case,. as will be shortly pointed out, refer to the combination 2 5 and we will assume that this combination 2 5 stands for the letter A. Therefore, assuming that the key 26 shown in Fig. 1, with its two contacts )@60, represents the key A, I' will now trace out the manner in which the'- type-bar X of the letter A in the receiving machine will print its character when the A key 26 in the sending machine is depressed It will be observed that the Contact connects by wire 63 with the segment section p which is known as No. 2 section, and the contact 59 connects by wire 64 with the segment section s whichis known as No, 5

lsection. All these contacts 55)*60`61, are

adapted when the key 26 is depressed'to be brought into electrical interconnection, so that the key will be in series with all these In depressing the sending key 26, the three ,spring contacts 552-60--61 are pinched together and a cireuit made through the lower contact 61 which energizes the transmitter 23 and breaks the line, releasing the pendulums, as we have already described. ThisV pendulum releasingvcircuit, or transmitter circuit, as I havecalled it before, isv broken, however, 'the moment brush6 leaves ythe end section n; thus again 1establishing or -closing the main line circuit. But as the brush (i sweeps across its` segment toward the other end p. the mainline circuit is broken twice as the brush G passes over sections 71 and .s3-in the following manner: The circuit controlled by section p passes from battery 2S through wire 31, transmitter 23, wire 27, key 26, contact 60,- wire G3, section' p, brush 6'pendu1um A, wire 29, to battery. The closing ofthis circuit is but momentary,

I of these armatures has and breaks the instant the brushleaves section p. The second -circuit through av is closed over the same'route, except that the current now passes through contact.59 andl wireY G4, instead of Contact 60 and wire 63. These two circuits made through sections p and s react through' the line, and wide sections cf of the receiving segment 9 in the receiving machine in the following manv ner: At the same timel that the brush 6 on pendulum A connects with section p to break the line circuit, the brush 7' on pendulum B is contacting with section c ing segment 9 close a circuitwhich will energize magnet 72 which is. the second magnet Vin' series. Likewise, when the brush V6 of endulum A passes over'sections the brush lum B will be passing over the relatively wider section f' and close a corresponding circuit to the magnet-74 which is the fifth in series., The way in which these circuits ,Y through magneten- 74 are closed islas follows: When the brush 6 is on contact p the line circuit is broken at this moment so that the relay 25' in the receiving machine is inert, allowing its armature 25b to contact with the contactmember 75 by reason of the action of the spring 75. l The contact ofthe armature 25h with Contact 'closes a circuit which flows from the battery 28 through wire 3l', rela armature 25", contact 75,

wires 76 and? magnet 7l, wire 78, section c', brush 7', pendulum B', and wire 29', back to the batteryv 28'. Energizing this ma net 7l acts on certain selective mechanism wich will be described shortly. The moment, the

brush 6 of pendulum A passes section p the transmitter'circuit is again broken Aand the line closed, 'energizingthe relays and breaking the circuit at 7 5 through-magnet 71 by the attraction of the armature25 by the relay 25. Similarly, when brush 6 of pendulum A contacts with sectionc'the line circuit is again broken and a magnet'circuit established through magnet 74 and section f',-

,the circuit being traced from battery 28',A

of the receivof the receiving machine to of penduwirel, armature 25h', contact 75, .Wire\76 magnet 74, wire 7 9, section f', brush 7', pendulum B, wire 29', to battery 28'. This circuit is -again broken as soon as the brush 6 of pendulum A passes over sections. The operation of the selective mechanism to select -the type-bar X corresponding to the magnets Tl- 74s, and print, is as follows: Referring to Fig. 5,' where the magnets 70- 7 1-72?3 74 are seen in plan, it is observed that` these magnets have respective i armatures 70 71'-72"-73'-74, and each a corresponding latch` member '70L adapted to'control. the movements of a series of selector combs or rack*v bars 80,-\8l-8283-.84, through the -en- @agement and disengagement of the latches 02% with the corresponding projections 80'- 81-82-83-84, on the respective bars 80-81, etc.` Each one of these bars has a number' of slots 86 along its front edge correspondingI to the number of keys 26 of the keyboard. Each one of these slots is just large enoughvto permit a locking lever 90, Fig. 2, to'enter when permitted. rl`here is one oit these locking levers 9() connected with each key 26 and corresponding type-bar X (of the receiving machine), and whenever one of these levers 9() enters a series of Iregistering slots 86 in all the live bars 80 8182- 83-84, the character corresponding to the depressed key 26 of the sending machine will print, as will be seen shortly.

The several bars 80-81-82-83-811 are .normally pulled in one direction and in opposition tothe retaining means 70"t by suit able means, as the springs 110.` Energizing any of the magnets 70, etc., will attract its corresponding armature TW-717, etc., re-

leasing its corresponding hook 70 vfrom the respective. projection 80 or 81', whereupon the spring 110 will throw the bars 80 or 8l,

etc., so released, in one direction. These bars are suitably mounted tor reclprocation insult-able guides in the machine frame, and

whenever a bar is pulled over by its coil spring it moves until it strikes the armature plate 111 on the magnet 112. It is by `means of this armature 111, as- I will point out laterathat the bars are pushed back in opposition to the springs 110 to engage the bars with the latches 70a.

Arranged 1n the pendulum magnet circuit of the magnets Bw 1s a magnet 87, and

whenever the pendulum magnets are ener gized, magnet 87 will also be energized and attract its armature 87 This armature 87 controls a circuit through a. magnet 88, and magnet S8 acts on a normally retracted, springactuated armature S8 which connects with and operates a slidable frame This frame' 93 is supported in brackets and extends across and inthe path 'of the series of locking bars 90, so as normally to prevent any of these locking bars 90 from entering the slots 86 in the rack-bars 80-81, etc., until the pendulum arrives on one or the other of the end sections of the segments and closes the pendulum magnet circuit; this pendulum magnet circuit, as We have seen, closing the circuit through the magnets 87 and 88. Thus, assuming that one or more of the rack-bars or combs 80-81, etc., have been moved to bring a vertical line of slots 86 in these bars into juxtaposition with a corresponding locking bar 90, and

further assuming the pendulums to be swung y reason of the action of a suitible spring 96; therel being one of these springs 96 for each bar 90. 1

The engagen'ient of the biir 90 in a series oi' slots SG carries the lower hooked end 113 of tho bar forward underneath a rod 1111 carried by a rocking frame 115 which is fulcruzned at 116. A spring 11.7 acts on the frame 1,15 to carry the rod 114 normally above and out of the path of the hooks 113. This rocking trame 115 is operated by a magnet 118, Fig. 2, the circuit of which is closed at 119 by the inward rocking of the bar 90. The moment this circuit is closed lthrough magnet 118, frame 115 is rocked,

pulling down on the hook 113 of the bar 90 which is engaged withV theslots, and this acts on a bell-crank 120 to rock the inner end of a key member 26 in the receiving-machine, pullingl on a rod 121v which connects with a corresponding type-bar X to print the desired character. This type-bar X atthe moment of printing closes another circuit at 122 which is in a circuit with the magnet 123, and this magnet 123 acts on an armature 124 which in turn acts on a sliding frame 125. This frame 125 has a crossbar 126 which pushes out the locking bar 90 to disengage it from its slots 86, thereby breaking the printing circuit through magnet 118. At the same time that magnet- 123 is energized, the magnet` 112 which is on the same circuit is energized, and its' armature 111 is attracted. to -push back all the combs or rack-bars 80-81, etc., which have been thrown forward, and cause all these rack-bars again to be caught by their latches a.

From the foregoing, it will be understood that to print 'the character A which I have before assumed to be represented by the combination 2-5 and the Spring contacts 551-60 which connect to the sections -p-s and act through sections ,cf-f and It makes no difference which way the pen.-l

dulums swing, except that they both always swing in the same direction and practically at the same rate of speed, and simultaneously. However, exact synchronism between the two pendulums is not necessary, since the sending sections 0, p, q, r,

are only s about one-tenth of the width of the receiving sections b', c', (Z, e', f', thereby mak-l 'lliere iiiig'ht he a diltei'ciice ot one-eighth of an inch iii the. relativo travel ol the. tii'o pcndiiliiiiis Without any adjustment heinel necessary*- A single swingl ot. thc peiiduluius in either direction completely :ii-ross the segr# ments causes the character to print, depen-ling' on thc key cle-pressed.
