LOUIS M. POTTS, OF BALTIMORE, MARYLAND, ASSIGNOR TO THE ROWLND TELE- GR'APHIC COMPANY, OF BALTIMOREJVIARYLAND, A CORPORATION OF'NEW JERSEY.

AUTOMATIC TELEGRAPH..

Ben it known that I, LOUIS M. Po'r'rs, a citizen of the United States, residing at Baltimore city and State of Maryland, have invented certain new and useful Improvements inv Automatic Telegraphs and the Like, of which the following is a specification.

The principal object' of this invention is the transmission of intelligence by automatic telegraphy, though the said invention in some of its aspects is applicable also to the operation of type casting or type setting machines, `and the rapid production or reproduction of printed matter of various kinds.

For the purposes of the present description, I have selected as a specific application of my invention, the case in which it is used as a .rapid automatic page printing telegraph, wherein the messages are automatically transmitted in multiple line form and received' and automatically printed in the same or substantially the same form. In such a system I have ucombined the rapid, the multiplex, and the printing telegraphs in one, wherein the valuable features of each are selected and practically all of the objectionable features of each are gotten rid of.

In order to more fully ldescribe this form of my invention, reference will be had to the accompanying drawings wherein- Figure l represents one of the telegraph forms prepared for sending; Fig. 2, a diagram of a form of the sending apparatus and electric circuits; 3, an enlarged fragmentary top plan ViewA of the sending blank and one set of brushes; Fig. 4,'a diagram of a form of the receiving apparatus and electric circuits; Fig. 5 is a diagram of a form of receiving apparatus and electric circuits arranged to automatically reproduce or re.

prepare al sending form for transmission; Fig. 6, an enlarged det-ail sectional view of the perforator :used with the apparatus shown in Fig. 5; and Figs. 7 to'lO inclusive represent respectively the sending, receiving, combination lcommutators and type-wheels in development.

In the following description I shall take up rst the sending form, then the transmission of messages by means of said forms.

Specification of Letters Patent.

I Patented Dec. W, 19?@9. Application filed J u1y 6, 1905. Serial No. 268,494. I v

The sending f0rm.-The sending fjorm consists of a sheet or page of paper or other suitable material having thereon a plurality of impressions arranged in accordance with a preselected code, and, if desired, a printed or typcwritten character corresponding to each code impression or combination of vimpressions representing such character.

These impressions may consist of perforations, embossments or any'other forms of impression which will accomplish substantially thc same result. "Ihe message is impressed on the blank in a series of horizontal lines as in ordinary writing, and when scribed in one form in' Jthe Patent No.

713,497, to Henry A. Rowland, granted November 11,1902, wherein eleven circuits of ,a keyboard are combined two-and-two to eifect a large number 'of combinations, each vof which effects the transmission of a different signal. d

" For the lpurpose of explaining how the perforations are arranged on the sending form according .to this code, let the form (Fig. l) be divided by a series of imaginary horizontal parallel lines of'four groups, indicated by the dotted lines lettered a, b, c, d, e, f, g, h, z', y' and k, and let each of these lines correspond to an electric circuit. Then,

as in the Rowland system, byF combining these circuits two-and-two, fifty-live combinations maybe effected, each of which may be made to transmit a different signal or character, or perform some other function. In the present system these circuits are combined two-and-two by'arranging for each character, symbol', orfsignal, two perforap tions in a vertical line, and each perforation of a combination 1n a sepaate horizontal line. For example, the cod varrange- I metal contact ring 104: of the local automatic ment' of perforations to produce the letter A" consists of a perforation on the horizontal line I; and a perforation located div 'rectly thereunder on the horizontal'line The code arrangement for the letter J consists of two perforations" located one above the other` onthe c and 'i lines, respectively, and so on. Each vertical line ofl -perforations forming a combination is' 1'0 spaced a suitable 'distance horizontally ffrom Athe next adjacent combination. At the same' time that the form is perforated, the charvacter or symbol representing the combina-v tion of perforations, Amay be printed orl typewritten thereon, preferably directly above or beneath the code perforations. yIn the yspecimen illustrated in Fig. 1, these printed characters are directly beneath the code perforations. In this way the mes- 20 sage may be easily read and mistakes,

' readily detected before transmission-y Each sending form is provided with al seriesvof auxiliary perforatlons 2, alo g one of its edges, preferably opposite the commencement of each line of printed matter.- These perforations, as will hereinaftermore l fully appear, register with retaining devices on the transmitting apparatus for imparting motion to the form, and act also as a l.means for'accurately placing the forms in the transmitter each time in the proper position. These sending forms may be prepared in any suitable way,` and I do not herein claim any, pecificmechanism for accomplishing this.'v

vThe telegraph circuits and apparatus.- These are shownin one form in Figs. 2, 3, 4, 5, and 7 to 10, to which reference will now fbe had, and more particularlyfirst to Figs. -2, 3 and 7. In the presentlcase, the main line current is an alternating current of Va frequency of about 100 complete cycles per secfond, and is lead ofl' from the secondary of a transformer 94, having an intermediate and two-outside terminals. The intermedi-v ate terminal is connected to earth, and the outside terminals connectedrespectively to the tongue contacts .95 and 96 of a main linejl transmitter 97,A so that Ithe current vwhen sent to line through contact 96 differs 180 in phase from current sentto line through con-- tact 95. This transmitteris of arform of Well known polarized transmitting relay having two independent electromagnets 98 and 99 arranged to act on the pivoted tongue' 100, which iselectric'ally connected to the metallic'r side 101 of the'gmain line. The

f windings of the magnet 98 are connected through a resistance 102 to wire A leading 60' to the positive pole of al source of direct cur- \rent supply. One terminal of the windings of the magnet. 99 is connected through a smaller resistance 103 Ito the positive wire A', and the other terminal to a continuous .tator could operate in` conjunction with one of such automatlc transmitters and those in;

the one operating with .the segments in they Spective segments. v

The brushes of each group 10G-109' are 110.

transmitting apparatus.' `This automaticv transmitting apparatus consists, among other segments is separated from the next adjacent group by three segments represented 8j by the unshaded segments `(see Fig. 7). Such asending commutator is designed for use with two four-line automaticv transmit# ters for `automatically transmitting a maximum offour lines of matter abreast. If al greater number of lines are to be .transmitted-a greater number of groups of segments wouldbe employed. vIn the case shown, the segments of one-half of the sending'commuthe other half with the other of suchtransmitters. Since these local automatic'trans-- init-ters may be identical, I have shown onlyl right hand half of the ring 105, F ig. 2, such segments being indicated by the groups S', S2, Ssf and S4 in Fig. 7. The elevenseg-` ments of each of these groups are electrically.

connected respectively to eleven separately insulated contact brushes of each ofthe l four groups of brushes 106,107, 108 and 109;

that is, the eleven brushes in group 106, for d l eXample,vareconnected each toa separate segment of group S.; the brushes in -group 165 107 similarly connected to group of S2, and so on. In'the diagram only tWofbrushesin each group are sh'own connected to their re-l spacedv apart va vdistance corresponding tothe distance between the horizontal dotted lines a, b, c,- d, e, f,"g, 7L, z', -j andk on the sending form, Fig. 1 ,and all fof the brushes are accurately adjusted to have theircon- 115. vtact points lie in a straight hne, extending longitudinally across' the top of a rotatable' metallic cylinder 110. In sending, the form 111 is inserted between the brushes and cylinder. Four guidepins 112 on the cylinder 120 are' arranged to register with .and pass through the four perforations4 2 in the sending form, thereby holding it to the cylinder. This arrangement also insures the placing of lthe form on the cylinder each time in the l proper position.

Asa means -for imparting rotary motion' 'to the cylinder 110, I have shown a ratchet Wheel 113 mounted on the end of the cylindershaft 114 and adapted to b eoperated 13d eeaeaa @y by a pawl 115 carried by an arm 116 mounted loosely at one end on the shaft 114 and resting-at its other end on a cam 117 carried upon a shaft 118. rIhis shaft 118 carries an arm 119 `which drives the sending comunitator brushes 120 and 121, the former resting on the rin `104 Aand the latter on the ring 105. Both o ward. The commutator brushes are driven preferably at a constant speed by a small electric motor, not shown, and their angular velocity is such that the time consumed in passing'over each of the grouped segments is equal to the time of a half of a complete alternation ofy the vline current, so that for each segment swept over by the brushes 121, a

semicycle of the alternating current will pass to line. This result may be obtained by driving the alternator which produces the line current by the same motor which drives the sending commutat-or brushes. The tongue of the transmitter remains, under-the influence of the magnet 98, normally against the contact 95, so that the alternating current passes to line no rmally through this contact. Electrical connection may be established be- .tweenthe cylinder 110A and the negative wire B inany suitable way or through a brush 123, resting on the shaft 114.

The receiving circuits and apparatus- The 'receiving apparatus consists, among other parts, of a main line polar relay 126,

having its coils connected in the line as shown.

The tongue contacts 127 and 128 of this relay are connected each to a point near an gend, of a resistance 129 'connected across a di- 40,.rect current circuit' of `preferably 110 volts.

From an intermediate point in said resistance. is led oit a wire 130, to which is tappedV a. number of branch wires 131. Each of these branch wires connects to one coil terminal of each of the polar relays af, b, o', Il', e', j, g', t, j and 7c', which ,I shall herein designate selecting relays. The

other coil terminals of the eleven selecting relays n. to It" are connected respectively to eleven consecutive segments of the segmental ring 132, which ring together with the continuous metal contact ring 133, I shall designate the receiving commutator The segments of the ring 132 correspond' in number, grouping and .angular position exactly to the'segments of the sending commutatorring 105. l I

For each group R to RS of the receiving commutator segments, there is a bank of selecting relays, andv the coil terminals of \these relays not connected to the common return 130 are connected respectively to the segments of the receiving commutator just as the brushesI 10G-109 are connected to the segments ofv the sending commutator. It

said brushes are, however, electrically connected'. The pawl 122 is` 1'0 merelyto prevent backward rotation of the Icylinder when the pawl 115 moves backwill, therefore, be understood that while I have shown only one bank of selectingrclays, there would be eight such banks it all l ofthe eight groups of receiving segments are used, or only four banks with the record- 7o ing device actually shown. The connections of all otthese banks of relays are identical,- so it is not necessary to show but one. In' the bank of relays shown, two' are shown with" their coils connected to the receiving commutator as by wires 134 and 135. The other relays are similarly connected to the remaining segments ofthe group adapted to operate with the bank of relays shown.

The selecting relays a. to lc are so wound :3o and connected that the coils of relays a, c', e', g, and 7;- receiye current each time that the main line relay tongue engages contact 127, for example, in such a direction as to send all their tongues against their back g5 stop contacts. Likewise, the coils ot' the remaining selecting relays, namely, b', d, f, i la. and j, receive current in such direction each time that the main line relay tongue engages contact 128, for example, as to send 9o vtheir tongues againsttheir forward contacts also. Normally, therefore, all of the selecting relay contacts remain against their` back Istop contacts. The tongue orthe mam line relay is connected as byl wire 136 With the 95 contact ring 133.

Electrical connection is established between successive segments of the ring'132, and" the ring 133, by brushes 137 and 138. 'Ihesebrushes are driven in accurate synbhronism with the brushes of the sending commutator and occupy corresponding angular positions. vVhile synchronous motion of these two sets of brushes is an essential requisite ofthe system herein shown, the specific method of or means for obtaining this synchronism forms nd part of my present invention, since any one of several 4methods may be employed. I prefer, however, to employ the system of synchronizing 110 forming the subject of my invention seti forth in U. S. Patent No. 726,750, granted to the Rowland Telegraphic Company, April 2s, 1903. V, y

4'Ihe receiving commutator and selecting 115 relays coperate, in the case shown, with four combination commutators, C, C2, C3' and .C4 and with a series of relays to operate recording devices. These combination commutators consist each of two continuous 1 20 metaly contactrings 141 and 142 and between these and insulated therefrom are two insulated segmental rings 1.43 and 144. In the form shown, these rings 143 and 144 f contain each the same number of segments 125 as the vsending and receiving commutators respectively, and the segments of the two lrings are ar anged opposite each other, that is, they do ot break joints. In each half of the rings 143 and 144 are -forty-one 130 combination segments, represented by the "shadedsegments in Fig. 9. The combination segments in the left hand half of the commutators C', C2, C3 and C4, Fig. 4, co-

operate with the receiving segments R to R4 and operate one recording device, the one shown, andthe combination segments in the opposite half of saidcommutators coperate i with the receiving segments R5 to -R8 to 1o operate the other recording device. 'That is to say, the set commutators are so mounted and adjusted that the combination segments for operating one recording device occupy angular positions diametrically opposite the groups .of receiving segments with which they coperate. The ob]ect of this arrangement will more fully-hereinafter appear. w

Each pair ofcombination segments. in the l -left hand half of the commutator C4 '(lower alf of Fig. 9) is connected to a dierent combination of two wires leading respectively from thceleven forward contacts of the selecting relays a to la. By a pair of combination segments is meant a segment with one ring (143) and one occupyingl a corresponding angular position in the other ring (144)A thereof. Calling the eleven wires lea ing from the contacts of the eleven sev lecting relays a, b, 0, d, e, f,.g, It, i, y' and c,

it will be readily seen that wires a and 0 may be connected respectively to one air of combination segments; wires a and to another pair ofsuch'segments; wires a, and e'to another pair; wires a and f to'another air; and so on until the forty-one pairs o segments have been connected to adifl'erent combination of the eleven wires. This com'- bination arrangement is fully vdescribed in the patent to Henry A. Rowland, No. 713,497,

-' commutator brushes.

a straight line and occupy angular positionscorresponding to the brushes 137 and 133 of the receiving commutator.

The recording devices, one only of which is shown, consist each, among other parts,

of four type-wheels 150 mounted on the shaft 149 or driven in synchronism therewith in any suitable manner. These type-- wheels are; so mounted thateach characteron the 'periphery .thereof 4will correspond angularl'y with-'a vpair of segments .in the rings 143, 144 constituting the combination aras-14 of segments to 9 and 10). 7 v

printthat character (see Figs.

Beneath lthe type-wheels is a paper carrying cylinder 151 vhaving annular recesses 152, one directly beneath each type-wheel.

Into these recesses extend four metal printing levers 153, pivoted as at 154, and having each' at one end a platen vlarranged to strike upward and send the paper 156 against the type-wheel. These printing levers are operated by four electro-magnets 157 located beneath their ends opposite the platens. The cylinder -151- is carried ona shaft 158 to which it is made fast, and upon this shaft is a ratchet\fwheel -159 operated by apawl 160 carried byj anarm 161 piv-l oted at one end on the shaft 158, and enga-ging near its other end a cam 162 carried byv the type-wheel shaft. Backward motion of the ratchet is prevented by the auxiliary pawl 163. This ratchet and pawl cam operated mechanism constitute a means for impartinga step-by-step'motion to the paper by-stepvmotion of the transmitting .cylinderlio.

The printing magnets are'operated in four -relay circuits, each of which is controlled by one of the four relays 164. Each of these relays has a magnet coil connectedy in series betweenthe posltive pole of a source of direct current and a ring 141 ofone of the combination commutators, the other'contact ring of each of said combination commutators being connected to .the negative pole of said source of current. The other v magnetl coils'of the relays 164 are-connected in series between the positive pole of said source, of currentand stationary contacts 165 arranged to'be en agedby spring contacts 166 on the ends o the respective printing" levers, which are in turn -conp'ected to Y lthe negative pole of said source of-'direo't current.

' The operation" is as follows.: A sendin form, such as. shown in LFig. 1, is prepare in any desired Way, and placed upon the cylinder 110, as shown in Fig. 2. Each revolution of the cam 117 causes the pawl 115. to step the ratchet 113 around a vcertain distance, and this imparts a step-bystep rotary motion to the cylinder 110.- After a few of such steps, the first line of perforations on'the form extending longitudinally of said cylinder will be brought b eneath the brushes 106-109. By .referring to Fig. 1, it will be'seen that this first line of perforations extending vertically of the sheet includes a perforation on the o line and one on the i line ofthe top group; no

erforations in the second group; a per- L i line current.

121 reach the other segments connected to Masai;

Therefore the b shes of the group 106 which are in line (ith the-c and z' perforations will make cbntact. therethrough with the metal cylinder 110, and likewise with respectto the brushes of the other groups which lie in line with the first line of per forations.

lVhen the brushes 121 reach the first segment in their path, connected to a brush which engages a perforation in the sending form, this completes a circuit, which, assuming that the segment engaged is the one connected to wire 124, may be traced as follows: from the positive wire A through resistance 103, coil of transmitter magnet 99, contact ring 104, brushes 120 and 121, segment of ring 105, wire 124, brush of group 106 engaging the cylinder 110 through the first perforation on the 0 line in the top group (Fig. 1), through cylinder 110, brush 123, back to the negative wire B. The circuit thus completed energizes magnet 99 of the transmitter, and causesit to draw the tongue 100 over against the contact 96. The tongue, however, remains there only so long as t e brushes 121 are passing over the seg ment connected to the wire 124. The effect of this is to change the line connections of the transformer 94 and send to line a semiy cycle of opposite sign to the normal. A local circuit is also completed through the coils of transmitter magnet 99 when the brushes 121 reach the segment connected to wire 125 causing a second reversal of the Likewise, when the brushes the brushes of the groups 106-109 which engage the cylinder 110 through perforations in the sending form, two line impulses will be reversed for each pair of such segments. The effect of these reversed seini cycles is to cause the tongue of the main line receiving relay (see Fig. 4) to remain, each time its coils are traversed by such reversed semicycles, against the opposite contact to that to which it would have been sent had no reversal taken place, and the etfect of this is to cause two of the selecting relays to receive current in a direction opposite to the normal, and this will cause them to send their tongues against their forn ward contacts.

Let it be assumed that the rst reversed line semicycle causes the tongue to the main line receiving relay to stick against Contact 128 instead of going over to contact 127, as it would have done normally, and let it further assumed that at that instant the receiving commutator brushes are in engagement with the segment connected to wire 134. A circuit will then be completed which may be traced as follows: from the positive side of the resistance 129, through Contact 121 and tongue of the main line relay 126, wire 136, ring 133, receiving commutator brushes, the segment of the ring 132 thereunder, wire 134, coils of selecting relay c, wire 131, wire 130, back to the intermediate point of resistance 129. The'current passing thus will cause the tongue of the selecting relay c to be sent against its forward contact for the reason that the main line relay tongue is against contact 128, causing ,current to traverse the coils of selecting relay c in a direction opposite to the normal. In a similar manner current is sent through the coils of the selecting relay z" when the second reversed semicycle causes the tongue of the main line relay 126 to stick' against the opposite contact to which it would have been sent by a normalcurrent. The tongues of selecting relays c and al having been sent over against theirforward contacts, a circuit is completed throughl one of the coils of the relay 164 as soon as the brushes 146 and 147 of the combination commutator arrive upon the combination of segments connected to the wires139 and 140 connected to the forward contacts of the selecting relays operated. Assuming that the brushes 146 and 147 have reached said segments, the relay operating circuit .may be y traced as follows: from the positive wire A2 leading from a source of direct current supply, to wire 167, left hand coil of one of the relays 164, wire 168, contact ring 141, brushes 145 and 146, segment of ring 143, wire 140,forward contact of selecting re lay c', through the tongue of said relay to the tongue of relay z" (all of the tongues of said selecting relays being electrically connected) forward contact of relay z", wire 139, segment of ring 144 connected to said wire, brushes 147 and 148, ring 142, wire 169 to the negative wire B2 of the source of current supply. This circuit causes current to flow through the left hand coil of relay 164, and this sends the .tongue 170 of said relay against contact 171, which completes a circuit through the printing magnet 157, which circuit may be traced as follows: from the positive wire A2, through wire 172, winding of print magnet 157, wire 173 relay contact 171, tongue 170, wire 174, back. to the negative wire 132. Current passing through this last named circuit energizes the print magnet 157, and causes it to attract one end of the print lever 153, sending the platen thereof against the paper in front of the character on the type-wheel which corresponds to the'combination of segments of the combination commutatoi connected to the wires 139 and 140. This operation prints the letter J the first letter of the .first word onthe sending form, Fig. 1.

When the print magnet `attracts the end of the print lever, the contact 166 is brought into engagement with the stationary contact 165, and this completes a restoring circuit which may be traced from the positive wire lio A2' through the right hand magnet coil of the relay 164,'Wire 175, contacts 165 and 166, print lever 153, and through Wire 176 to the negative Wire B2. The completion of this circuit causes the right hand magnet of relay 164 to draw its tongue against its back stop to its initial position, breaking the circuit through the print magnet. When the transmitter brushes 121reach the next group of segments, those in Fig. `2 connected to the group' of brushes 107, no transmission is effected, for, as Will be observed from the letters I and W7 Will be transmitted.

These letters Will be printed respectively by the tvvo print levers on the left (Fig. t),-

While the print lever next to the lever 153 .Will remain at rest, for, as explained, there are no code perforations at this time be- Vneath` brushes 107.

After the brushes 121 have passed over the four groups of conimutator segments connected to the brushes 10G-109, t-he cam 117 operating the arm 116 causes the ratchet Aand pavvl mechanism to step thel cylinder around a predetermined distance, that is, the distance ofpone rovv of perforations eX- tending longitudinally of said cylinder to the next, whereby the brushes ofthe groups 10G-109 are brought into line with the next roW of perforations, and When the brushes 121 come in contact With thesegments connected to the brushes contacting with the 'cylinder through this next line of perforations, the main line transmitter Will again be operated as above described to reverse an impulse of the line current for each segment so connected. This Will send over thel linel the next'series of signals. After this, the perforated form is again spaced up to the next perforations as described, and so on until all of the perforations. have beenA brought beneath their .respective brushes.

After the proper printing levers have been operated to print a line of characters abreast, such as the first row or line, J -"I and WP (Fig.1), the paper 156 is spaced up by the cam 162 acting on the arm 161, Which in turn acts through the ratchet and pawl mechanism to impart a limited rotary motion to the cylinder 151. The paper is then7 ready to receive thenext transverse line of characters, after which the cylinder 151 is again stepped around, and this [process is carried on until all of the message is printed on the sheet or page 156.

If the `code piforations' arrive simulta-7 neously beneath the several groups of brushes V106-109 representing like char-- acters, these characters Will all be printed simultaneously, one on each line. This is so for the reason that combinations of segments representing like characters in each half of the several combination commutators all occupy corresponding angular positions. Therefore, the combination commutator brushes Will arrive upon like combinations of segments simultaneously and this will cause all of the print magnets and levers to act simultaneously to print like characters.

This novel method of printing, Which 'consists in printing a plurality of lines of matter abreast, eliminates entirely the necessity of stepping the paper up from line to line. This not only eii'ectsA a great saving in time by the elimination of an entire step in the pivotal practiced methods of printing, but

also gets rid of all of the mechanism necessary to effect such a step. Moreover, by operating two printers, one with each half of the -four combination commutators and duplexing the line,- as shown in the patent' to Henry A. Rowland, hereinbefore referred to, or otherwise, the line may be Worked to its fullest capacity at all times.

The autom/tic reproduction, of sending forma- An arrangement of circuits and apparatus for accomplishing this is. shoWn in Figs. 5 and 6. In. carrying out this feature of my invention, I add to the printer already described, an automat-ic perforating device consisting, among other parts, of two stationary punch bars 177 and 178 separated by a sufficient space toallow the paper or form to pass between them as shovvn. In the upper bar 177 are a series of roups of perforatingpins 1.79*- normally he d up by the springs 180.l There are eleven of these pins in each group and Vone group is located in front of each type-Wheel of the printer. For eachv of these pins there is a sepa-rate lever and these levers rest respectively upon the tops of the several pins. In the drawings I have shown two vof these as the levers 181 and 182. These levers are arranged for actuation by-separate magnets 183, 184e and carry, at their outer ends, contacts 185, 186 which are arranged to engage,

at the proper time, stationary contacts 187 and 188.' In each perforator lever operating magnet there is a separate relay, to the for-J Ward contact'of each of which the positive coil terminal of each of the said lever operating magnets connects. In the diagram I have shown two of these relays as the relays cf", 2. These relays have independently Wound magnets, one of which acts as'an actuating magnet and the other as a restoring magnet. The actuating magnet. coils v189, 190 of these relays are so Wound that current passing through them normally sends their gafas-4atongues against their baclrstop contacts. The actuating magnet coils 189 and 19() of thesev relays are connected in multiple respectively with the printer coil terminals of the several selecting relays d-z, While t-he restoring coils 191 and 192 are connected respectively which leads to the negative pole of a source of direct current. One terminal of the actuating magnet 197 is connected to a segment 200 in the combination coinmutator U,

while one-terminal of the restoring magnet 198 is connected to a segment 201 of the same combination commutator, but lying in the opposite half of said commutator from the segment 200.. These segments are entirely independent of the combination segments.

T he operation of the automatic perforating arrangement is as follows: Let it be assumedthat, owing to a/reversal oftwo line current seinicycles from the normal, the .main line relay` causes current to be sen-tthrough the right coils of selecting relays c and c" in an opposite direction tothe normal when the brush 187 arrives upon `the segments connected to wires 184L and 135, as was described in connection with the operation of printing. Then the brush 137 arrives upon the segment connected to wire 181, current in an opposite direction to the normal will also be sent through the coils of actuating magnet 189/of relay C2. This will cause the tongue of that relayV to be sent against its forward contact, and in doing so will complete a circuit from the positive pole of local current supply through Wire 199, tongue of relay 196, contact-195, Wire 194, coil of magnet 1841, forward contact and tongue of relay C2 back to the negative pole of current supply. The magnetv18t Will,

therefore, become energized and attract the one end of lever 182, and causing the other end thereof to send the perforating pin thereunder through the paper. This operation also sends the contact 186 into engag'ement with the stationary contact 188, and `this completes a restoring circuit which may be traced as follows: From the positive pole of the local current supply by wire 198 to ithe coil of the restoring magnet 191 of reilay Gthence to contacts 188 and 186, lever 182 back to the negative pole.' This causes The windings of these magnets, as well as the tongue of thev relay, connect to a common ret-urn wire 199 relay C2 tobreak the circuit through the coils of magnet 184, When the lever 182 will return to its normal position.

Before the brushes of the combination commutator C reached the position shown, they passed over segment 200 and in doing so completed a circuitfroni the positive pole v of the local current source through the coil 197 of relay 196 and this caused its tongue to be sent against the contact 195. When the brushes of the commutator C arrivev upon vsegment 201, a circuit is completed through the coil 198 of relay 196 and this restores the tongue ofsaid relay to its normal position against its back stop contact. By a similar sequence of operations, the lever 181 is operated-by the magnet 183 when the brush 137 arrives upon the segment connected to the wire 185. In this latter case, relay it acts instead of relay C2. For each character transmitted overJ the line, thereforea separate combination of pins may be made to automatically ,impress on the form a different combination of perforations, by which means l am enabled to automatically reprepare the sending forms. @ne of these auto matic perforators may be used with each printer or without the printers.
