application filed December 1, ll-J15. Serial No. $4,427.-

To all whom it may concern:

Be it known that l, ALLEN l). Cannwnnn, a citizen of the United States, and a resident of New York city, borough of Broole lyn, county of Kings. and State of New York, have invented certain new and useful Improvements in Electrically-Operating 'lranslators, of which the following is a descriptii'in.

My invention has reference to improved means for selecting and setting in operative position anydesired number of members or parts, in a desired succession or sequence. whereby various operations or functions of certain electrically controlled apparatus may be etl ected,

My improvements are particularly adapted for use translators at transmitting or receiving stations, or both. in telegraph typewriter systems. and may be utilized in such systems to cause the selection and operation of various elements for printing or type writing and other working functions of a printing or typewriting machine.

In my application for Letters Patent for improvements in electric controlling systems, filed Sept. 5, 1914:, Serial No. 860,318, I have set forth a system whereby, by means of two translators located at dili erent sta-. tions and rotatingisochronally, a signal sent from one of the stations. in the form of a group of impulses, may selectively control a series of relays under the immediate control of the translator at the other station. Said application discloses means whereby a starting impulse is sent from the transmitting station, prior to the transmission of each signal, for starting the operation of the receiving translator, and other means for stop- V ping; the translator at the completion of each signal. lhe receiving translator is illustrated as being" adapted to successively operate contactscontained in a series of circuits, to thus place said circuits under the control of a hu l relay, which is energized upon the reception of each impulse. In this avay, the circuits are selectively operated in accordance with the character of the signals received. These circuits control relays which in turn control the operations of the recording device, and thus ellect the recording oi? the signals transmitted.

In my application for Letters Patent for improvements in telegraph typewriters, filed April 10, 1915. Serial No. 20,386. l have set forth a telegraph printer having a type wheel or member adapted to be rotated and moved longitudinally to bring its type to a.

printing position, together with a hammer for effecting printing from such type, and devices to cause various operations of a paper carriage and other functions ofthe machine. In said application I have illustrated also an electrical system adapted to control the various magnets of such printer, in conjunction with a line relay and controlling relays through which circuits are conf trolled by a translator by signals sent from a keyboard at a transmitting station, substantially. in accordancewith my invention set forth in my aforesaid application Serial in. 860,318.

My present invention has to do with distributors or translators which are ofgeneral application to electrical systems for "the transmission of intelligence, and to record ing or printing devices adapted for use in connection with such systems; However, in order that a more complete understanding may be had of my present improvements, I have illustrated them herein as applied to a system and arecording device similar to those described in my aforesaid applications.

it is to be understood, however, thatthis particular embodiment of my invention is intended merely as an illustration of one of the many uses to which it may be put.

My improved I 'anslator or distributor embodies a series of movable elements and controlling means therefor, the controlling means being in turn controlled by the Sig ,nals received. The movable elements may serve any desired purpose. For example,

they may operate contacts for controlling.

printing: magnets, such as are shown in my application Serial N 20,386, to position a type wheel, or they may be used to operate. mechanical means for selecting independent type carrying members, such as type bars.

The controlling means above referred. to include,,as herein illustrated, a controlling 'memher correspondingto each of the mov'- able elements and means for effectingthe successive operation of these members during the reception of each signal, irrespective of its character. In addition, the controlling means include a device which is open ated only uponreceipt of an active impulse, by which term. 1 mean an impulse of a given characteristic, such, for example, as a long impulse as distinguished from a short one, a positive impulse as distinguished from a,

6 brevity, p

tion as used in connection with a system of bers are so. arranged'that the movement of. one ofthem will cause corresponding movable element only in case the operation of its the impulse-controlled device is operated at the time at which the movementof the memr occurs. In other words. 1 the conjoint 16 action of the impulse-controlled device and the controlling membes corresponding to a given movable element, is required in order that that element may be caused to operate. Thus, since the controlling members operate ,m regular succession during't-he recep- 26 able element or elements operated .tion" of a signal, irrespective of the charac- "=ter-"of the signal,v and since the impulse- 'conti'olled device operates only upon' the reception of an impulse, the particular movby a given signal are determined by the timed relation of the impulses comprising that signal.

In addition to the above described parts, providejmeaus for restoring all of the 80-movable elements to normal position upon 86 forth and the completion of each signal.

y invention further comprises noveldetails of improvement and combinations of parts that will be more fully hereinafter set then pointed out in the claims. eference is to be had to'the accompanying drawings forming part hereof,, wherein.

, ported in frame 1 ,tion, of a translator embodying my invcn-- In the accompanying drawings, the nu- 'members 2 retained in normal position by latches or bell-cranks 4, one for each member, which are pivota'lly supported upon a. suitably carried by frame 1.

In the example illustrated, the upper ends of the latches-t normally engage stops or notches 2 of members 2, as illustrated in Fig. 5, the projections 2 adjacent to said stops normally limiting the rearward motion of said latches under the influence of springs 6 coacting with said latches. Springs may be suitably supported in the frame, as upon a cross bar I. When the latches are moved from the stops 2, as illustrated in Fig. 9, the members '2 arc ada )ted to drop to rest upon correspoinling latches aided by springs 2. To cause the latches 4 to be operated to release the corresponding members 2, I have shown controlling members or arms 8 pivotally supa at 9, said arms being provided with pawls 10 shown pivotally supported upon said. arms at 11, and normally under the influence of SpringslQ- connecting said pa\\'ls with said arms, the tendcnc of said pawls licingtoJn'io i ndei iehe latches l. Said p'awls ai-ejnor ially held in check against the, tension of springs 12 by means of a bar 13, adapted to be movcd to permit said pawls to pass under the corresponding latch 4- (Fig; 5)) and to restore said pawls to thcirnormal positions (Fig. l The parts 4, 6, 8 ricd on a sub-frame 7.

In order to reciprocate the pawls 10 to cause operation of latches 4, I have shown a shaft 21 supported in suitable hearings in frame 1 and having cams 21*,21", 21", 21 and 21 adapted to operate-the respective arms 8, in relation 'towhichsaidcams are set. I have illustrated the armsS as provided with cam followers or projections 8. adapted to coact with said cams to opcratc said arms. In the example illustrated, there are pairs of opposing cams for each arm 8, and tivc sllch pairs oi cams to coact with five such arms, It will be understood, however, that there may be any desired number of arms 8. and one or 'more cams for each arm, according to the number of steps shaft 21 is; to be rotated for a complete signal. Screws 14 carried by Sllb-flilllll. 7 and coacting with arms 8 are adapted-to limit the downward movement of arms 8, and to ad-. just the time of contact of the cam followers o r projections 8 with the corresponding cams.

income shown to successively cooperate with the cam followers 8 on the several arms 8, so that the rotation of the shaft 21 will effect. the

successive upward movement of the several arms 8. It is apparent that if the bar 13 is withdrawn to allow the pawls 10 to be swung by the springs 12 into position underneath the latches 4, at the time when any arm 8 is elevated by its cam, the corresponding latch 4 will be swung about'its pivot and Wlil per mit the corresponding member 2 to drop down into the position shown in Fig. 9.

Since the arms 8 are all successively operated during the reception of each signal, the particular member or members 2 to be operated will be determined by the particular time or times at which the bar 13 is withdrawn. Thus, for example, if the bar 13 is withdrawn at the times when the first and fourth ,members 8.are"being elevated, the first and fourth members 2 will be allowed to drop. By providing means for withdrawing bar 13 atthe reception of each impulse, thetiming of the impulses in a given signal will determine which of "members 2 will operate upon the reception of that signal.

l have illustrated bar 13 controlled by the armature A of a magnet A, shown carried by frame -l,whereby when magnet A is energized bar 13 will be moved to one side to permit pawls 10 to pass under, the latches 4, and when magnet A is denergized, all of the five-pawls 10 will be pushed bacleby such bar to their normal positions shown in Fig.

'5. Spring a connected with the frame and suitably connected with-bar 13 orarmature A, serves to cause bar 13to retain pawls 10 in normal position. The energization of magnet A will occur in accordance with the character of the signal on the line, as here inafter set forth.

' by frame 1.

After a complete signal has been sent on the line to the translator, themembers 2 that may have been operated, as well as the correspondmg. latches 4, for such signal, may be restored to normal in any suitable manner. For this purpose I have illustrated a restoring bar 15 shown beneath. the free ends of members 2,

and pivotally supported at 16 from the frame, which bar-15 is operativcly connected with the armature L of a magnet L carried A spring connecting restoring bar 15 of the armature L with the yoke of magnet L serves to normally retain said bar retracted from members 2, and an adjustable stopc eoacting with the arm carrying" barlfi of armature L (Fig. 5) acts as a back stop for the armature and enable desired adjustment of the armature and bar 15 relative to the magnet L and members 2. respectively. Magnet L is adapted to be energized at the completion of each signal or group of impulses comprising a signal for restoring the parts to normal, and in the example illustrated the sixth member 2 is utilized for such purpose. As shown in Pig. 3, the bar 13 does not cooperate with the pawl l0 mounted on the fifth arm 8, and, therefore, this pawl 10 will operate its latch -l each time it is elevated by its cam. irrespective of the position of the bar 13. its herein shown, the fifth arm 8 elevates pawl it), as Wellas the fifth pawl 10 controlled by bar 13. since the latter pawl 10 and pawl l0 are carried by the same arm 8."

From the foregoing it will be understood that the desired members :2 may be operated in succession, in accordance with the opera tion of the corresponding latches l. as controlledby the signals on the line, and that the operation of the members 2 may be utilized to effect the operation of other desired devices. in the example illustrated in Figs. 1 tOlQ, and 12, l have shown contacts to be controlled by the members 2, for in turn controlling circuits to effect operation of some suitable recording device. in this particular embodiment of my invention, it is assumed that my present improvements are utilized to control magnets in a printing: telegraph system, such as that. set forth in my aforesaid. applications, Serial Nos. 860,318 and 20,386. it will be understood.

however, that the members 2, instead of bctrates one method of utilizing members for a. purpose other than the closing of elcclrb cal contacts.

in Figs.- l, 2, 5, (l, 7 and 8, thearms 2 a re illustrated as controlling contacts, 1, 2,"3. l, 5, and E, respectively. The first tire of these contacts may be arranged to control the circuits of magnets l, 2, 2 3". l 4 and 5, similar to the type-wheel positioning magnets ol my aforesaid applications. and the sixth Contact E. which is preferably operated at the completion or each signal. may bc'arranged to control magnets for effecting the operation of the printing device. and for restoring the various parts of the translator or distributor to normal position.

The upper Spriliggnembel's of the contacts 12 2". 3", 4", 5 and ll tend to move downwardly, to close the contacts, but are rcstrained from so moving by the insulators :1 mounted on the i'nembers 2, when the latter in normal position. When a member 2 is allowed to drop, however, the corresponding contact will close.

in addition to the individual contacts under the control of their respective members 2, it may be found desirable to provide other contacts for selecting operating magnets to be actuated upon the closing of the contact E at the completion of the signal. Such magnets may serve to effect the special operations of the printing device, such, for instance, aS printing, word and line spacing, etc. lVhen these latter contacts are employed, any suitable controlling means therevvfor maybe provided. 1 preferably, however,

arrange these latter contacts so that they arecontrolled by the same members 2 which control the individual contacts above referred to. For example, I may so arrange these latter contacts that one or more of them are operated upon the combined operation of certain of the members 2, that others are operated upon the operation of any of the members 2, and that still others are opcrated upon the operation of certain of members 2, acting individually. Thus, the set of contacts G, G is operated when all of the first three members 2 drop, the set of contacts H, H is operated when any one of the five members 2 drops, the set of contacts 1",2, i and a" is operated upon the dropping of the fourth member 2, and the set of contacts j, j is operated upon the dropping of the fifth member These sets of contacts may be arranged to control the operation of a particular magnet in a group of magnets,

\ suchas O, P, N, W, R, Q, T, S, Fig. 12.

As a means for controlling contacts G and G I'have shown a bail or analogous mo 'able arm G overlying members and pivotally supported at g upon sub-frame 7. adapted to control normally closed contacts G and normally open contacts G said bail G being shown provided with a projection 9 having insulation adapted to coact with the lower spring (Figs. 1 and (l) to normally keep contact G closed, which in turn keeps contact G open by raising spring g". An intermediate spring rests upon insulation 9 In the example illustrated bail G is normally held up by the first. second and third members 2 (Fig. (3) and is only allowed to drop when said three members are operated in succession. because if any one of said three members 2 is not operated on a signal, the bail G cannot drop. as it will be held up by such nonopcrated member. Said bail G is shown provided with a cut-away portion G above the last hrce members 2. permitting the bail to drop or swing down when released by the first three operating together, (Fig. (3 A stop bar (Fig. 5) carried bysub-fra1ne T beneath bail G serves to limit the downward movement of said bail when released by the first three members 2. \Vhen bail G is 'aised upon the restoration of members 2 to their normal positions by bar 15, circuit will be broken at G and closed at G.

The contacts indicated at HQH are controlled by a second bail H located beneath members 2 and adapted to be pushed down by any one of the first five of said members, but not by the sixth member 2*. The bail H is shownIpivotally supported in the subframe '7 at h and at its outer end is provided with a projection h having insulation h adapted to be engaged and normally held up by the spring it that carries one member of the normally open contacts H the other member of said contact being shown carried by a. spring h u A spring 71. carries the other member of normally closed contact H, and said spring hlnormally bears againstinsulation h". As illustrated in Fig. 1, the springs of the contacts G, G H-', H are carried upon the side of frame 1, and insulated therefrom and from each other, and the-projections g, h operate in apertures a in the side of frame 1 (Fig. 1). The bail H is provided with a cut-out part at H beneath the sixth member 2* (Fig. (i), so that the bail H will not be affected by the dropping of the member 2", which occurs at the conclusion of each signal.

Contacts 2', i i 11 are shown carried on springs supported by and insulated from the frame and from each other. Thespring restsupon insulation a and the springs i, z" are normally held elevated by the insulation i mounted on the spring carrying the upper member of contact 1". Frpin Fig. 7 it is apparent that when the member 2 corresponding to contact 4 is allowed to drop. contact 4: will close, and two contacts 2 i will be permitted to open, and the contacts i, i" will close. The two springs i are controlled simultaneously by the bridge member 2'" shown carried by upper spring of contact 4 and in turn carrying the insulation 2", (Figs. 5 and 7).

The fifth member 2 which controls the normally open contact 5 also controls normally closed contact 7" and normally open contact 7' thcrcabovc, in the manner described with respect to contacts 1'. i. The contacts j, j are carried by springs normally insulated from frame 1, insulation j on the top spring of contact 5 coacting with the spring j of contact Contacts 1' carried by two springs, the lower of which rests on insulation (I, may be arranged similarly to that shown in Figs. 5 and 7. the arrangement being such that when the fifth member 2 drops, circuit will becloscd at 5". and circuit will be broken at 7', and circuit will be closed at j \Vhi'le in the foregoing description I have referred to members 2 as being adapted to selectively control electrical circuits, it will be understood that such members may control means for producing mechanical operations. either alone or in conjunction with electrically operating means. In Fig. 11 the member 2 s shown adapted tooperate a rod or other element X, which in turn may cause cordance Withthe operation of a aeo orc operation of any other suitable lover or part 7 indicated at Y, whereby any desired operationsfof' a printing or type writiug machine or other apparatus may be contro led in acbcrs I have-shown the rod or the like I; plovided with, a stop X adapted to be engaged by the extension *2 of member 2 to operate the red X when member 2 drops, as released by the latch 4. lt will be understood that any desired number of members 2 and corre sponding controlling devices may be utilized according to the result to be accomplished.

In order to render my improved translator effective it is necessar to provide some means for rotzoiing the shaft the receiving station, and preferably this rotatron 1s isochronous with the rotation oi: a

somewhat similar shaft located at the send ported upon frame 1, and

by springs 33, 34

Any suitable means may be ing station. provided "for effecting this rotation, ethic means may be operated continuously, or :37 be started prior to the sending of each "nal andstopped at therompletiou of each signal." Nhile the particular means our ployed for this purpose form no part of in? present invention, I have herein illustra i the shaft 21 as being operated step by ep during the reception of each signal by means similar to those disclosed in my storesaidapplications, which means I will now describgthe reference numerals used herein being for the most part the same as these applied to corresponding elements of said a-p- 'pli'cati ons.

A spring 2? connected with said pawls tends to keep them in contact with said toothed Wheel. {in adjustable stop 28 shown adapted to coact with pawl to limit its upward movement, causes the cam shaft to stop at the props" point being advanced each step bysaid and astop 29 is adapted to be engaged pawl. 2 3i to prevent overthrow oi the shaft when operated by said pawl A spring 36 conwith the mam itrame,

Magnet'QQ is in a local circuit, including normally closed contacts 2., shown carried 1 and 12),, supthe ported. upon suitable insulation on frame. The arm or lever 23 carries a stud 35, which is shown pro ecting thrpugli a hole 36 in frame l, the stud on the first depression of armor lever 23 depressing a contact lever or arm 3'21 suitably supported. upon the frame as at 38 and carrying in sulation 39, adapted to operate upon a 34 to break the circuit at contact 32 as shown in Fig. L'to open the'local circuit of the translator magnet 22. Contact lever 32' is retained in its downward position by a latch pawl 10 that is pivotally supported as at 4:1 upon anad'justable plate or arm 41 that is pivoted as at an upon frame 1, and adapted to be adjusted angularly around said pivot to vary the time of engagement of stud with latch 40. Said plate or arm 41 is shown provided With a slot receiving a screw 41 in frame 1 to retain. said plate or arm in set position.

Latch 4:0 is normally controlled by a iring 40 and said latch hasa stop portion adapted to engage the projecting portion oi of contact lever 23'? to retain the local circuit of the magnet broken until the armature and its aim 23 have been restored use to normal, and thereupon the stud 35 on arm23 engages the projecting arm. of atoll 40 to release arm 3'? to permit contacts lo again close each time magnet 22 is deiaed. r 'i e cam shaft 21 carries, preferably at enmity thereof, a unison cam 31, the of which is to insure a complete operation of one set of cams of the t for a given signal on the line- In pie illustrated, since there are two each arm 8, I provide the unison 'aith two opposing projections corto each one-half rotation of the and the shaft is given oneion for each series of five cams, cams are arranged in pairs. If s of cams were arranged on as illustrated in my said apthe cam tslication 1" No. 860,316, the cam shaft would be one complete rotation for a given on the line, and if more than two cams were provided for each armii the can; shaft would be given a corresponding rue unison cam in example shown, provided with opposing teeth 31, is in the normal position oi rest (Fi t r g ge a tooth on a spring 4-6 carried by and insulated from the frame and in electrical connection with spring 34, whereby upon theiirst forward movement of she 't 3;, resulting from the actuation of the line relay 51 by the initial starting impuise received over the line 50, a tooth 3P from. tooth-4C5 and permits contact 427 on spring 46 to engage a contact 48 that ls-connected with one Winding of relay 49 1T3}. Thus-the working circuit, of magnet 22 is closed at the beginning of an operation, and is maintained closed at 4:87

until practically the completion of each one a Assuming that a combination'or group of a starting signal and five selective signals in desired combinations are sent on the line for effecting a complete cycle of operations for selecting and printing a character or for other functions of a telegraph typewriter or printer, the first; or starting signal sent on the line wilt cause operation of relay 51 .Whose armature 18 connected to one side of battery 58, and a circuit will be established from said battery through contact 54, re-- cam shaft 21 to rotate one step, whereupon through spring 34. contacts '32 and magnet unison cam 31 will release tooth and permit contacts 47 and 48 to close, as above described. A circuit will then be established from battery 58, through left hand winding of relay 919., through closed contacts 48, 47

22 to ground, and through variable inductance 60 and capacity 60*, Whenever contact .32 is closed thereafter by the action of magnet 22, as reviou slyexplained. The operation-of re ay 49 causes the starting circuit'of magnet 22 to be broken at contact 56, and thereafter each time the relay 51 is operated by a line impulse a circuit will be 1 established from the battery 58 through the armature of line relay 51, through resistance 59, a-rmatureiw, front contact 62 of relay 4 through winding of said rela I i the e ergization of said mag et.

and-through magnet A;-to ground, to effect 'It will be understood that operation of magnet A can take place only after a starting signal on the line has caused a' partial rotation of Ottlll shaft 21. Thereafter, as

cam shaft 21 is stepped successively, the

arms 8 will be raised in succession and their pawls 10 will be reciprocatedout of contact with their corresponding latches 4, except when a line impulse effects the energization of magnet A, as before described, and the consequent withdrawal of the bar 13 from the pawls. Whichever pawl 10 is elevated while the bar 13 is thus withdrawn, will rock its associate latch 4 to release the corresponding member 2 to permit said member to drop, as illustrated in Fig. 9. Upon the cessation of the impulse on the .line, relay 51 is dei ncrgized, the circuit of magnet A is broken, and bar 13 1s movedback to restore rnembers 2, serve to include in the circuit lowing examples 1' ally of the pawls 10 to normal position. The

operated pawls and latches will then assume the positions shown in Fig. 8. v I

Relay 49 is designed to prevent a'repeated operation of" magnet 22 after a complete cycle of operations of \such magnet for a given signal has been performed, and, as,

shown herein, it operates also to connect? magnet A to the circuit controlled by line" relay 51 after each starting impulse has been received. Relay 49 removes the startin circuit and magnet 22 from the, control 0 the line relay 51 upon the establishment of a working circuit throughcontact 48. This circuit retains relay 49 operated as lon as contact 48 is closed, because ofjcurrent owing through magnet 22 and resistance 63. Whenever .line relay 51 operates to energize magnet A it also energizes a holding wind-- ing of relay 49, so that if a circuit should be retained closed by reason of the continuops energi-zation of relay 51 until after magnet 22 has completed a cycle of operations, magnet 22' will not again be energized because relay 49 will remain o erated by reason of its holding winding Being energized, as long as relay 51 is energized.- At .the end of a cycle of'operations of magnet 22, unison cam 31 opens the circuit of mag-' net 22 at contact 48, and the cam shaft comes to rest. The opening of this circuit restores relay 49 to normal, provided line relay 51 has returned to normal.'

As above stated, the contact E' is closed' I at the completion of each signal, as fore}? 1.00 ample by the fifth cam'on shaft 21. f, This contact may control the circuit of-a number of operating or special function magnets, such, for example, as those illustrated ati M, N,O, I, Q, R, S, T in Fig. 12. Contact E also controls a circuit through the restoreing magnet L which operates member 15'to restore the members 2 to normal position" after the reception of each signal, but the magnet Lis so timed that its operation will 119 be delayed 'until after the operation of" the selected special function magnet or magnets. Bearing in mind the fact that the contacts 1, 2, 3, 4 and 5, which are operated the corresponding membersa2, control mag-. nets 1 2 2 3 3 4 and 5 which serve, for example,to position a liype wheel, and that the contacts G, G H, z", i, i 2, and 3" 7' which are also operated by controlled by contact E selectedlmagnets'of the series M, N, O, P, Q, R, S, T,'for operating the telegraph typewriter or printer, the operation of my present improvements should be readily unc erstood from the folxlfla Assume first that the signal received comprises an active impulse atthe first time period and one at the third time perlod, but none at the second, fourth or fifth periods.

income contacl H,it being remembered that this occurs when any one the members ,2 drops. This opeation of contacts ll. and H in-' cliid s n'iagnets '1, Q and ll in the circuit ofcontact E. Then, upon the dropping of the member 2* at the completion oi the signal,

contact E is closed, which results first in the energization of magnets T, Q and R, to effeet the operation of the printing hamn'ier, and such other"operations as are necessarily incident to the printing of a character, and

4 second in the cnergizalion of magnet Lto restore the parts to normal position.

Assume now that the signal received includes impulses at the first, second, third and fifth time periods, with no impulse at the fourth period. The first, second, third and fifth members will drop successively, operating thecontacts 1 2, 3 and 5; Also, since all of the first three members '2 have dropped, contact G will be closed and contact G will be opened, and since the filth member has dropped, contact ,7" will be opened and con tact j closed. This results in including. the

magnet, P in the circuit cl contact E, and

upon the dropping of the member 2* to close this Contact, this magnet alone will first be operated to efi'ect the desired operation of the printing device, and then the restoring; magnet- L will be operated. v

above stated, I have described my invention herein as applied to the system and printing device of my former applications, merely as an example of one of the many uses to which is may be put. ll should be understoiid, therefore, that: my 'wenlion is not, lin'v, to any particular application Mercer, nor to the particular embodiment herein illustrated, since it is obvious that ,rnany changg'cs may-be made therein without,

departing from the spirit of my invention.

What I claim is: i
