- the present invention relates to quotation systems and app ratus and more particularly to special signals are incorporated withinthe compass of other signals,
- Stock quotation systems generally employ three classes of signals commonly identified as item selection signals, price or recorder operating signals and range or qualifying signals. 0! these three'classes, the first, or item selection signals,
- this secondary qualifying signal commonly referred to as a range signal, was transmitted in the form of a separate and individual signal, making the total number of signals September 18, 1937, Se-
- an object of the present invention is tojprovide telegraph signal code, apparatus employing a predetermined length message and utilizing the full capacity of each signal interval of the message when its primary employment the series is operated, the iimction being indicative of the conclusion (ii! a message, then a special perforation is made in the control form which serves as an index and regulatory mark during the subsequent use 01' the control form in' th controlled apparatus.
- Another object of the present in vention is to provide means for making an endof-message mark on a controlform as an incidental response to the operation of a keylever which. relates to the concluding class in a sequence.
- the above and other objects of the present invention are accomplished by impressing a secondary selection signal simultaneously with the four price signals, thereby maintaining the total number of groups oi signals at seven while utilizing the unused space of the hundreds, tens, units, or fractions position for correspondingly identifying the particular signal group as being either "high", "low", last, or "close.
- the invention provides a keyboard peri'orator arranged with means for controlling storage devices .to inelude in a selected group oi other perforations an additional perforation representative of the stock price range.

- each code bar 22 is capable of assuming two positions, so that the several of them combinedly are capable of assuming thirty-two permutative positions. Accordingly, the depression of each of the item keylevers presents the five code bars permutatively into a position individual to the particular keylever, while the depression of II and it, while wiring diagram of a modified keybar a isin its left hand either the units or fractions keylevers, similarly,
- a sixth code bar 22 generally similar to the five bars 22 is located at the rear of the others. As may be seen in the illustration, the inclined surfaces 24 of this bar which are located beneath. the items and digits keylevers II and it are all inclined in one direction while those which are located beneath the fractions keylevers ii are inclined in the other direction, so that the depression of a keylever II or moves this lever right-' wardly while the depression of a keylever i6 moves it leftwardly.
- This bar 22 will be identi fled hereinafter as the sixth hole code bar, and its function is to cause the perforation (if a sixth hole 22, Fig. 4, in the fractions perforation alignment which, as'described in the original application, serves to phase the relationship between transmitting and receiving apparatus by changing the polarity of the start pulse of each complete quotation message.
- Each of the six code bars 22 and 22 at its left 22 are each connected to one end of an interposition bar 2
- is stable 32 having two projecting arms 24 and 25 pivoted at”.
- a solenoid 21 disposed below the table 22 has associated with it an armature 22 which is of which is provided with a shouldered portion pivotally connected to the table 22 and is adapted,
- a set of punches 22 Located above the interposition bars 2

- the central perforations 42 which will be referred to hereinafter as the feed perforations are by armed sprocket 45 carried upon'a shaft 45 suitably supported in the frame- I work (not shown).
- the feed sprocket 45 is rotatably advanced one tooth step at a time concur- I rently with the reciprocation of table 88 in the following manner.
- a bracket 41 is secured to the table as and is pivotallyconnected at 48 to one arm of a lever- 48 pivotally secured at so that as the projection 41 reciprocates vertically together with table 88 the former is oscillated concordantiy.
- lever 48 carrying a spring loaded pawl 52 thrusts the latter rightwardiy,
- gear wheel 54 which engages and drives a pinion 55 carried upon a cam shaft 56.
- cam 51 On shaft 58 is secured a cam 51 which is provided with an apex 58 normally disposed in a vertical position. as shown and which functions as the active members of a sequence switch 58.
- the driving ratio between pinion and gear 54 is'such that for each complete revolution of shaft 58 ratchet wheel 58 and its assembly advance seven radial steps.
- solenoid 81 The energization of solenoid 81 iscoincident with the depression of any of the keylevers ii, l5 or l8 by reason of the following circuit arrangement.
- One terminal of the winding of solenoid 81 is connected to a positive source of current 5i and its other terminal is connected.
- switches 58, 84 and 85 are parallelly connected with the item keylevers ll; switches, 81 and 68, with the digits keylevers l5; while switch 69 is connected with the fractions keylevers" it.
- the several contacts 88 to 68 inclusive and cam 51 constitute a sequence switch 58 which is operated progressively in a clockwise direction.
- switch 58 which incidentally carries two sets of contact points 14 and I5, one set 14- of which relates to andis connected with the solenoid 81, while the other set 15 closes a circuit for a magnet I5 located to the left of the special bar 25.
- Switches 81, 58 and 58 are of similar construction to switch 86 insofar as each is provided with two sets ofcon- 'tact points, one set each of which is connected parallelly for closing the circuit of range magnet 15, whilethe other set of each prepares the circuit for its respective class of keylevers.
- Each of the keylevers I I has associated with it tact points 89 disposed in the path of apex 58 of the sequence switch 59 towards the end of its .rotary cycle.
- relay 88 armature 83 Upon the 'energization of relay 88 armature 83 is attracted, breaking the lockingcircuit and releasing the four relays '11 to 8! which are then in readiness to store the qualifying'rsignal of a subsequent quotation.
- the presence or absence of a fifth perforation 88, Fig. 4 accompanying each of the digit or fraction'signals may control any desired qualification affecting the .associated message.
- the presence of -a perforation depending 'in which of the four positions it occurs, correspondingly qualifies the signal as being either -open,, high, low" or flast.
- each of the four positions individually is one mode'of controlling this qualification system and is the method employed in accordance withthe present disclosure.
- two or more of the four positions might be used permutatively in which case the presence or absence of a perforation in each of the positions determines the ultimate operation.
- Fig. l illustrates a perforated tape 44 as being the sole resultant of the keyboard device it will be 'understood, of course, that the several signals may instead of or in addition to being restored also besent out on a communication line.
- the code bars 23 and 25 and a transmitting distributor of any conventional type electrical signals corresponding to those afiixedto the'tape 44 may be transmitted to a remote station.
- notches in the special code bar II is best indicated in Fig. 5, the ones under the alphabetical character keylevers II and the numerical digits keylevers I5 being of such inclination as to cause code bar to be cammed rightwardly, while those under the keylevers I6 are of such inclination as to com code bar 30 -le1'twardly.- v v a
- the operator In manipulating a-keyboard perforator such as the one just described, the operator must introduce the qualifying signals before depressing those keylevers simultaneously withwhich the qualifying signalsare installed upon the record.
- Relay I8 is held locked by reason of the following locking circuit; positive potential I], winding of relay l8. locking armature l6, locking circuit 82, armature 83, through line' 84 to negative potential 83.
- sequence switch controls a set of contacts 63 through i! and II similar to that illustrated in the preferred form, except that these contacts control a set of individual latches III which mechanically restrain each group of key-levers, permitting them to be operated only in accordance with the first described sequence of operation.
- latches I II include hook portions which are adapted to eng cooperating lugs I02 integraily formed with each key-lever II, in the case of the range keylevers, and balls I2 in the case of the quotation signalling keylevers II, I, and I6.
- the latch members IOI are normally spring urged to engage their overlying lugs "2 except during such times that their particular unlocking magnets are energized through the progressive operation of sequence switdi 5!.
- An un-. locking magnet I03 is common to all of the latches IIII of the range keylevers II which when energized permits any one of them to be operated and correspondingly when deenergized, prevents any of them from being operated.
- Each keylever II has associated with it two jointly operative sets of contacts I and I05,
- relay I08 Upon thus being energized, relay I08 attracts its threearmatures H5, H6 and III achieving the following results. Armature I I5 contacts with its associated'point completing the locking circuit for magnet I08 from positive potential IIII, winding of relay I08, armature H5, conductor IIB, armature II9, to negative potential at I. Armature H6 breaks its contact with its associated point removing negative potential from the range unlatching magnet I03 and permitting the latches IilI of the range keylevers I I to become eflective inrestraining the further opera.- tion of the range keylevers. Armature III makes contact with its associated point introducing negative potential from over line I tothe items unlatching magnet I22, thereby withdrawing the latches III from all of the items keylevers II.-
- each class are controlled by a magnet individual thereto, which magnet is in turn electrically connected with one of the contacts of the sequence switch 55 (except item magnet I22), so that where in the first case the sequence switch merely prepared the circuits for eifectuating the keylevers II,'I5, and I6, in the instant case the corresponding contacts of the sequence switch 50 are provided with the several keylevers just as- I are illustrated inFig. 1, though they are not shown in this figure and alsothat a tape feed mechanism and sequence switch stepping arrangement forms part of the present structure which is operative in the same manner as the.
- solenoid 31' is in this case, however, directly controlled by the several multipled contacts H which in turn are under control of the universal bails I2.
- the circuit for energizing the winding of solenoid 31 is quite obvious and need not, as in the case of Fig. 1, be dependent upon the sequence switch 59, since the order of operation of the control switches H is in this case mechanically dependent upon the operativecondition of the several classes of keylevers for v closing them.
- Fig. 2 respond similarly to the preferred embodiment of Fig. 1 described. above, except for the following differences.
- the sequence of operation of the various sets 'of keylevers II, l5, I6, and I1 is positively and mechanically restrained so that if an operator, in attempting to depart from the proper sequence of operation, depresses the wrong keylever he may be apprised immediately by the resistance of the keylever that its depresslon isirregular, whereasln the preferred em-- bodiment, the keylevers were at "all times depressible but were effective only in their proper sequence.
- the additional pair of. contacts II3 peculiar to this embodiment which are located in thepath 'of apex 55 during the final portion of its cyclic movement are provided for the purpose of energizing an unlocking magnet I21 which restores relay I05 to normalcy in preparation for a subsequent cycle of operation.
- This magnet influences an armature II! which forms part of the locking circuit ill of relay I06.
- a perforating device su'ch as is adapted to accomplish this object and-which may be controlled by transmitting mechanisms of the ldnd described in the co-pending application referred to above, and which is capable of reproducing a control form similar to the form locallyprepared I by the transmitting perforator.
- a signalling line I extends fromthe transmitting station and is connected to a polarized relay I20 having an armature I3I operable between negative and positive sources of current I32 and I33 connected to a solid ring I34 of a distributor I35.
- Distributor I35 also comprises a segmented ring I35 and a rotatable brush holder- I31, the brushes I of whlchbridge the afore- 1o mentioned rings I34 and I35.
- magnet I42 is connected at one terminal with the start segment I 43 of distributor I and at its other terminal to an elecrical contacting follower I44 reciprocable between a pair of contacts I45 and. I46 which go communicate with negative and positive potential respectively.
- Shaft I also carries a pinion I41 which drives a gear I secured to a shaft I40 upon which is also carried a cam I5I which cooperates with the aforementioned follower I44.
- each storage relay I51 to I62 cooperates with a negative potential contact point I64 and is connected to one terminal of a selecting magnet I65, the other terminal of which communicates 'with positive potential.
- Each magnet I65 controls an individual selecting member I66, the several of which are pivoted on a common shaft I51.
- the selecting members I65 and their associated magnets I65 are located one in back of the other for purposes of clearness, but it is to be understood that these elements in the operative structure are in alignment as are also their asso- .clated levers I53.
- a stop-arm I15 is also secured to shaft I15 and its adapted to be engaged by a tooth I11' formed upon an armature I15.
- Th tabl I12 in receiving its motion from cam- I14 imparts a similar movement to'the several interpositionbars I53 above which are located a set of six punches I13 which form part of the punch die assembly as in the case of the per 5 forator of P 8. 1.
- certain magnets I55 are cyclically-energized while the-remainder of themremain deenergized in accordance with the particular code combination that is being recorded; Springs III of members I being more powerful than those in oilevers i66 over? come the tendencies ofthe latter during the de-, energized condition oi! magnets I65, causing the levers to assume the solid line positions as. illustrated, but when.
- an operating pulse is received by a magnet I63 which thereupon attracts its armature I16 releasing stop member I16 which travels in a counterclockwise direction through one revolution thrusting table I12 and bars I69 upwardly and amxingv a set of perforations in accordance with the positions of the several bars I69.
- the start pulse which energizes magnet I66 is received over a conductor I64 from the positive source of current I65 through the periodic intervention of a contactor I66 controlled by a cam I61, which is also secured to driving shaft I46;
- the gear ratio between shafts I49 and I46 is such that the latter rotates one complete revolution for each one-seventh of a revolution of the former.
- the apex of cam I 6I encounters the cam .follower I9I, raising the latter into contactual engagement with a negative source of current, thereby completing the circuit for the sixth magnet I92 over conductor I93.
- This magnet controls a sixth perforat punch which installs the sixth perforation 96 in the .same maner as described in connection with Fig. 1, and for the same purpose.
- the tape perforated by this mechanism is accordingly an exact reproduction of the tape at the transmitting station, all of the signals being electrically relayed from the latter except the last described sixth perforation 96, the making of which is entirely controlled by apparatus local to the perforation station, Fig. 2.
- Levers I66 thereupon are permitted .to assume positions corresponding to their respective members I66 after which armature I16 is again res leased, detaining the several levers in their assumed positions and permittingthe members I 66 to receive a new signal.
- an overlap of operation is afforded as between the members I66 and the'interposition bars I66 so that a new.

- Application for reissue rial No. 164,492
The present invention relates to quotation systems and app ratus and more particularly to special signals are incorporated withinthe compass of other signals,
This application is a division of copending application Serial No. 393,161, flied September 19,
1929, now Patent No. 2,134,005, granted October 25, 1938.
Stock quotation systems generally employ three classes of signals commonly identified as item selection signals, price or recorder operating signals and range or qualifying signals. 0! these three'classes, the first, or item selection signals,
- usually comprises three characters, each 01' which is represented alphabetically, while the eombination of the three in addition to graphically identi tying the particular stock to which the quotation relates, also permutatively controls the selection of the stock at the receiving station.
While there are twenty-six standard characters in the alphabet, the minimum requirements of a Baudot code system'to accommodate these characters is a five unit code which aflords a permutation oi thirty-two possibilities. A tour unit code is inadequate, afl'ording only sixteen possibilities. For this reason the first three quotation or item selection signals, which, as described above, relate to the three item selection characters, must include five units in each signal in order to aflordpermutative possibilities sufllcient to accommodate the twenty-six letters of the alphabet.
As contrasted with the foregoing requirements,
9, 0, and a blank so that the sixteen possibilities afforded by a four unit signal are adequate to accommodate each of theprice signals including the fractions signal. In accordance with the commercial stock quotation practice, fractional quotations are always in eighths so that its total requirements are" but eight possibilities ineluding V4. it, '56. V4. n lt- In addition to selecting and quoting a'particu-i lar stock. it is also desirable to quality each quotation, or in other words, to'periorm a secondary selection, whereby each quotation may be identifled in terms 01' "high", "low", "close" or -last;
that is, whether the particular quotation is the highest quotation of the day, the lowest, yesterday's close, or simply the most recent chronologically. Heretoiore, .this secondary qualifying signal commonly referred to as a range signal, was transmitted in the form of a separate and individual signal, making the total number of signals September 18, 1937, Se-
2. (Cl- 178-175) r \I required for each quotation eight, including .the
three primary selection signals and the tour price si nals. 7
Accordingly, an object of the present invention is tojprovide telegraph signal code, apparatus employing a predetermined length message and utilizing the full capacity of each signal interval of the message when its primary employment the series is operated, the iimction being indicative of the conclusion (ii! a message, then a special perforation is made in the control form which serves as an index and regulatory mark during the subsequent use 01' the control form in' th controlled apparatus.
Accordingly, another object of the present in vention is to provide means for making an endof-message mark on a controlform as an incidental response to the operation of a keylever which. relates to the concluding class in a sequence.
The above and other objects of the present invention are accomplished by impressing a secondary selection signal simultaneously with the four price signals, thereby maintaining the total number of groups oi signals at seven while utilizing the unused space of the hundreds, tens, units, or fractions position for correspondingly identifying the particular signal group as being either "high", "low", last, or "close. Specifically, the invention provides a keyboard peri'orator arranged with means for controlling storage devices .to inelude in a selected group oi other perforations an additional perforation representative of the stock price range. In orderto assure the proper sequence of manipulation, meansare provided, in-- cluding a sequence switch, for rendering t e var ioiis classes of keylevers oi .the peri'orator o tively eil'ectivein a predetermined succession.
A better understandingot the invention may be had from the following description, taken in conjunction-with the accompanying in which:
1 is a perspective view of a periorator illustrating the keyboard mechanism, and a wiring diagram showing associated therewith, one form of the present invention 7 bar such as may be employed in connection with the control of the end-of-message perforator In the following description, particular referen'ce will be had to the accompanying drawings in which like reference characters designate similar parts throughout the several figures.
The perforating mechanism illustrated in Fig. 1
I is provided with four general classes of keylevers.
Of these, the numeral N indicates the alphabetical or items designation keylevers which are lothe others in the illustration, relates to the range cated to the left of the keyboard and which upon being depressed engage a bail |2 pivoted on a rod l2 by means of depending projections H integrally formed with the keylevers. An intermediate set of keylevers l2 relates to the integer price characters and right hand keylevers It, the fractions price characters. A fourth class of keylevers II, which have been egr gated from or qualifying characteristics of a quotation. Of
, directly below the 6o. designation keylevers code bars 22 V ticular relationship the three first described classes of keylevers each is provided with a bail similar .to the bail |2 with the item keylevers while the several classes are pivotally carried on a common pivot red I 2. Each bail has individual to it an insulating block is adapted to engage a contact spring 2| when it is rocked about its pivot l2 upon the depression of one of its associated keylevers.
As illustrated,the groups of keylevers l5 and I2 are pivoted ona common shaft l2 and areprovided with a spacing comb. (not shown) while eachlever is connected to an individual return spring 22 for maintaining in andreturning itto its elevated position. The range keylevers may, if desired, be likewise supported on the rod l2 though; as will be seen in the course of the following description, their relative position with respect to theremainde'r of the keylevers is Below the aligned keylevers II, I! and II are supportedasetoffivepermutationorcodebars 22, which are provided with variously located inclined surfaces 24. Of the five code bars the foremost one 22 is cut away as at 22 in the region units and fractions keylevers in the region below the items II it is provided with the conventional inclined notcha 24 with which the remainder of the code bars 22 are provided throughout. The various inclined surfaces of the five bars 22 are eachindividuallyarranged with *respectto its bar so that the depression of. any one keylever of eachset engaging the respective thrusts them rightwardly or leftwardly as the case may be into a definite and pareach to the other.
Since each code bar 22 is capable of assuming two positions, so that the several of them combinedly are capable of assuming thirty-two permutative positions. Accordingly, the depression of each of the item keylevers presents the five code bars permutatively into a position individual to the particular keylever, while the depression of II and it, while wiring diagram of a modified keybar a isin its left hand either the units or fractions keylevers, similarly,
. affects but four of the five bars 22, the other one 22 being cut away as above described, so as not to beaifected by the keylevers overlying the cutaway region. It is possible that certain few permutative positions 'of the several code bars might be common between one of the keylevers of one set and that of another set, but, as will 'be explained, this apparent indistinction is taken care of by other means provided for distinguishing between one class of keylovers and another.
Y, A sixth code bar 22 generally similar to the five bars 22 is located at the rear of the others. As may be seen in the illustration, the inclined surfaces 24 of this bar which are located beneath. the items and digits keylevers II and it are all inclined in one direction while those which are located beneath the fractions keylevers ii are inclined in the other direction, so that the depression of a keylever II or moves this lever right-' wardly while the depression of a keylever i6 moves it leftwardly. This bar 22 will be identi fled hereinafter as the sixth hole code bar, and its function is to cause the perforation (if a sixth hole 22, Fig. 4, in the fractions perforation alignment which, as'described in the original application, serves to phase the relationship between transmitting and receiving apparatus by changing the polarity of the start pulse of each complete quotation message.
Each of the six code bars 22 and 22 at its left 22 are each connected to one end of an interposition bar 2| individual thereto, the opposite end 22.- Belowthe interposition bars 2| is stable 32 having two projecting arms 24 and 25 pivoted at". A solenoid 21 disposed below the table 22 has associated with it an armature 22 which is of which is provided with a shouldered portion pivotally connected to the table 22 and is adapted,
upon the solenoid being energized, to move upwardly rocking the table 22 clockwise about its pivot 22.
Located above the interposition bars 2| is a set of punches 22 supported in a block M and adapted to cooperate with a die member 42. When'a particular code bar 22 or the sixth code position, as viewed in Fig. 1, through its connection with a lever 22, it presents the shoulder portion 22 of its interposition bar 2| directly beneath one of the punches 22, but when. on the contrary, it is in its right hand position the shouldered portion 22 of its corresponding interposition bar 2| is not thus presented, but instead clears its associated punch,
so that-when thereafter the table 221s reciprocated, those punches 22 whose associated shoulders 22 are at that instant presented beneath their respective punches will thrust them into the die block 42 while such of them as are not thus present will fall to engage their punches peror form is advanced both in this and other apparatuses. In accordance with the present illustration, the central perforations 42, which will be referred to hereinafter as the feed perforations are by armed sprocket 45 carried upon'a shaft 45 suitably supported in the frame- I work (not shown). The feed sprocket 45 is rotatably advanced one tooth step at a time concur- I rently with the reciprocation of table 88 in the following manner.
A bracket 41 is secured to the table as and is pivotallyconnected at 48 to one arm of a lever- 48 pivotally secured at so that as the projection 41 reciprocates vertically together with table 88 the former is oscillated concordantiy. Upon its clockwise movement, lever 48 carrying a spring loaded pawl 52 thrusts the latter rightwardiy,
causing it to engage one of the teeth of a ratchet wheel 53 also mounted on shaft 46 and to rotate the latter one tooth distance in a counterclockwise direction, as viewed in this Fig. 1, thereby rotating sprocket wheel 45 and accordingly advancing the tape 44 leftwardly. 1
Also mounted on shaft 45 is a gear wheel 54 which engages and drives a pinion 55 carried upon a cam shaft 56. On shaft 58 is secured a cam 51 which is provided with an apex 58 normally disposed in a vertical position. as shown and which functions as the active members of a sequence switch 58. The driving ratio between pinion and gear 54 is'such that for each complete revolution of shaft 58 ratchet wheel 58 and its assembly advance seven radial steps.
The energization of solenoid 81 iscoincident with the depression of any of the keylevers ii, l5 or l8 by reason of the following circuit arrangement. One terminal of the winding of solenoid 81 is connected to a positive source of current 5i and its other terminal is connected.
over circuit 82 to one blade-each of the seven radially disposed contact switches 53 to 58 inelusive. Of the several switches, switches 58, 84 and 85 are parallelly connected with the item keylevers ll; switches, 81 and 68, with the digits keylevers l5; while switch 69 is connected with the fractions keylevers" it. The several contacts 88 to 68 inclusive and cam 51 constitute a sequence switch 58 which is operated progressively in a clockwise direction.
In its normal position apex 58. engages the flexible blade of switch 58, closing the circuit for one of the item keylevers ii. Upon depressing one of .the keys II the item bail l2 engages its contact spring 2|, closing the circuit at contact points 1i and completing a circuit from positive potential at 5! through the winding of soleoid 81 over line 82, through the closed switch 53 of the sequence switch 58, thence over line I8, contact points ll tonegative potential at 12. This energizes the solenoid 8i, reciprocating table 88 which thereupon performs a perforating operation, and advancw the ratchet wheel 53 one tooth distance, while at the same time rotating cam 51 one seventh of its revolution so that its apex 58 engages switch 84, which latter also relates to' the characterkeylevers ii. The depression of the next two character keylevers l I. responds similarly to the one just described, except that in each case apex 58 advancesgw-closing the contacts and 88, respectively.
After the depression of the third keylever ll apex 58 is presented opposite switch 58 .which incidentally carries two sets of contact points 14 and I5, one set 14- of which relates to andis connected with the solenoid 81, while the other set 15 closes a circuit for a magnet I5 located to the left of the special bar 25. Switches 81, 58 and 58 are of similar construction to switch 86 insofar as each is provided with two sets ofcon- 'tact points, one set each of which is connected parallelly for closing the circuit of range magnet 15, whilethe other set of each prepares the circuit for its respective class of keylevers.
Each of the keylevers I I has associated with it tact points 89 disposed in the path of apex 58 of the sequence switch 59 towards the end of its .rotary cycle. Upon the 'energization of relay 88 armature 83 is attracted, breaking the lockingcircuit and releasing the four relays '11 to 8! which are then in readiness to store the qualifying'rsignal of a subsequent quotation. Thus it will be understood that the presence or absence of a fifth perforation 88, Fig. 4, accompanying each of the digit or fraction'signals may control any desired qualification affecting the .associated message. As illustrated, the presence of -a perforation, depending 'in which of the four positions it occurs, correspondingly qualifies the signal as being either -open,, high, low" or flast.
It will beunderstood that several modes of practice may be adapted in accordance with this invention whereby this superposed signal perforation appearing in either or any of the four positions might be used individually or conjunc- I I tively with the other of the four positions. That is to say, the four successive signal positions may in themselves constitute a permutation code or each signal may effect a control independently of the other of the foursignals.
' I Inorder 'to control the range qualifications of a signal in accordance with the. present illustration, four. possibilities are necessary. Employing each of the four positions individually is one mode'of controlling this qualification system and is the method employed in accordance withthe present disclosure. Optionally, two or more of the four positions might be used permutatively in which case the presence or absence of a perforation in each of the positions determines the ultimate operation.
While the'mechanismdisclosed in Fig. l illustrates a perforated tape 44 as being the sole resultant of the keyboard device it will be 'understood, of course, that the several signals may instead of or in addition to being restored also besent out on a communication line. By providing a set of contactswith the code bars 23 and 25 and a transmitting distributor of any conventional type electrical signals corresponding to those afiixedto the'tape 44 may be transmitted to a remote station.
In accordance with certain systems of transmission, complete quotation messages are introduced'by a changed start pulse for pu poses 'of synchronizing quotation message cycles. To .accommodate' systems of this class a sixth perforation 88 is provided with the final or fraction row of perforations as illustrated in Fig. 4. The effect of this synchronizing perforation upon the mechanism of a receiving station is fully de- 7 scribed in connection with Fig. 3 of the parent application referred to above.
The arrangement of notches in the special code bar II is best indicated in Fig. 5, the ones under the alphabetical character keylevers II and the numerical digits keylevers I5 being of such inclination as to cause code bar to be cammed rightwardly, while those under the keylevers I6 are of such inclination as to com code bar 30 -le1'twardly.- v v a In manipulating a-keyboard perforator such as the one just described, the operator must introduce the qualifying signals before depressing those keylevers simultaneously withwhich the qualifying signalsare installed upon the record. It is'optional whether these signals be introduced before, intermediately with, or after the primary selecting of items characteristics, but in order' I8 attracts its locfing armature 86 as well as its control armature 93 maintaining the latter closed and preparing a circuit for the sequence switch 59 as follows. From positive potential OI'through the winding of range magnet 16,over line 95,
' In this manner the signal is stored in relay l8 awaiting the progress of sequence switch 59 when its apex 5i arrives opposite switch 61 at which time the prepared circuit is closed, energizing the range magnet 16. This attracts armature III which in turn moves the fifth bar'2ll leftwardly. causing to be presented the shoulder portion 32 of its associated interposition bar 3f into its punch effective position. When, thereafter, solenoid 31 is energized for the punch operation an additional perforation II is made. As illustrated inFlg. 4 thi perforation ill, in accordance with the present may p a in any of four positions, thereby determining the range of the associated message.
In Fig. 2, there is iilustrated'a modified keyboard .arrangement for accomplishing the same objects as set forth in connection with the foregoing preferred disclosure in a somewhat different manner. In all cases of similar elements, the same reference characters are used in this modified disclosure as were used in the preferred embodiment so as toobviate detailed description of duplicated structures.
In this case the sequence switch controls a set of contacts 63 through i! and II similar to that illustrated in the preferred form, except that these contacts control a set of individual latches III which mechanically restrain each group of key-levers, permitting them to be operated only in accordance with the first described sequence of operation.
These latches I II include hook portions which are adapted to eng cooperating lugs I02 integraily formed with each key-lever II, in the case of the range keylevers, and balls I2 in the case of the quotation signalling keylevers II, I, and I6. The latch members IOI are normally spring urged to engage their overlying lugs "2 except during such times that their particular unlocking magnets are energized through the progressive operation of sequence switdi 5!. An un-. locking magnet I03 is common to all of the latches IIII of the range keylevers II which when energized permits any one of them to be operated and correspondingly when deenergized, prevents any of them from being operated.
Each keylever II has associated with it two jointly operative sets of contacts I and I05,
the latter of which are multipledover a circuit 4 I06 extending from positive potential I", over a relay I08, thence through the circuit I06, contacts I I5, circuit I09 to the contacts 53, 64 and 65 of the sequence switch 59,. A source of negative potential I II is distributed around switch 59 over a'cir'cuit' II2 communicating with each of the contacts 63 to 69, as well as switch 3 of an unlocking circuit Ill. dition of contact 63 negative potential is supplied to circuit 'Ill9 and upon depressing any of the range keylevers I1 is extended through contacts Hi5 to the relay I08, 7
Upon thus being energized, relay I08 attracts its threearmatures H5, H6 and III achieving the following results. Armature I I5 contacts with its associated'point completing the locking circuit for magnet I08 from positive potential IIII, winding of relay I08, armature H5, conductor IIB, armature II9, to negative potential at I. Armature H6 breaks its contact with its associated point removing negative potential from the range unlatching magnet I03 and permitting the latches IilI of the range keylevers I I to become eflective inrestraining the further opera.- tion of the range keylevers. Armature III makes contact with its associated point introducing negative potential from over line I tothe items unlatching magnet I22, thereby withdrawing the latches III from all of the items keylevers II.-
By the normally closed con- Thus by depressing any of the keylevers l I and closing a contact "5, an operator prepares'the items keylevers foroperation while also pre'venting the further operation of any of the range keylevers. Where, however, the four perforation positions are to be used permutatively those keylevers which are to be depressed must be manipulated simultaneously because the operation of any one ormore of them disables the further operation ofiany others. g The range storage magnets TI to 8| are similar to those described with the preferred embodiment as are the circuit connections between them and the contacts of the sequence switch 59. The depression of any of the keylevers II closing a pair of contacts I simultaneously with the closure of contacts. I05 causes a locking of its associated storage magnet.
It will be understood, of course, that though twokeylevers only ofe'ach class I I, I5, and I6 are illustrated, that this is merely for-simplification of the drawings and that these are representative of a' set similar to the one illustrated in I! is collectively locked by a corresponding set of latches IOI which engage the lugs I02 of their respective universal bail I2. The several latches,
of each class are controlled by a magnet individual thereto, which magnet is in turn electrically connected with one of the contacts of the sequence switch 55 (except item magnet I22), so that where in the first case the sequence switch merely prepared the circuits for eifectuating the keylevers II,'I5, and I6, in the instant case the corresponding contacts of the sequence switch 50 are provided with the several keylevers just as- I are illustrated inFig. 1, though they are not shown in this figure and alsothat a tape feed mechanism and sequence switch stepping arrangement forms part of the present structure which is operative in the same manner as the.
preferred form. I
' Operating solenoid 31'is in this case, however, directly controlled by the several multipled contacts H which in turn are under control of the universal bails I2. The circuit for energizing the winding of solenoid 31 is quite obvious and need not, as in the case of Fig. 1, be dependent upon the sequence switch 59, since the order of operation of the control switches H is in this case mechanically dependent upon the operativecondition of the several classes of keylevers for v closing them.
The sequence switch 59 is normally in the position shown with the contacts 63 and I23 closed, the latter completing the circuit I24 for unlocking magnet I03 of the range keylevers I1, while the former supplies negative potential for energizing the relay I upon the depression ofany keylevers I1. The other unlocking magnets I22,
I25, and I26 remain deenergized, holding their respective classes of-keylevers' in a non-operable position and making it necessary for an operator to first depress one of the. range keylevers I1 before the item keylevers I I are yieldable to manipulation. r
In manipulation, the modified form of Fig. 2 respond similarly to the preferred embodiment of Fig. 1 described. above, except for the following differences. The sequence of operation of the various sets 'of keylevers II, l5, I6, and I1 is positively and mechanically restrained so that if an operator, in attempting to depart from the proper sequence of operation, depresses the wrong keylever he may be apprised immediately by the resistance of the keylever that its depresslon isirregular, whereasln the preferred em-- bodiment, the keylevers were at "all times depressible but were effective only in their proper sequence.
The additional pair of. contacts II3 peculiar to this embodiment which are located in thepath 'of apex 55 during the final portion of its cyclic movement are provided for the purpose of energizing an unlocking magnet I21 which restores relay I05 to normalcy in preparation for a subsequent cycle of operation. This magnet influences an armature II! which forms part of the locking circuit ill of relay I06.
It is frequently desirable to prepare a perforated tape in accordance with electrical signals transmitted from a remote station. In Fig. 3 is illustrated a perforating device su'ch as is adapted to accomplish this object and-which may be controlled by transmitting mechanisms of the ldnd described in the co-pending application referred to above, and which is capable of reproducing a control form similar to the form locallyprepared I by the transmitting perforator.
A signalling line I extends fromthe transmitting station and is connected to a polarized relay I20 having an armature I3I operable between negative and positive sources of current I32 and I33 connected to a solid ring I34 of a distributor I35. Distributor I35 also comprises a segmented ring I35 and a rotatable brush holder- I31, the brushes I of whlchbridge the afore- 1o mentioned rings I34 and I35. Brush holder I31 which is carried upon a shaft I40 frictlonally driven from a suitable source (not shown) is normally withheld =from rotation by an armature latch I30 pivoted at I and under the control of u magnet I42. The winding of magnet I42 is connected at one terminal with the start segment I 43 of distributor I and at its other terminal to an elecrical contacting follower I44 reciprocable between a pair of contacts I45 and. I46 which go communicate with negative and positive potential respectively. Shaft I also carries a pinion I41 which drives a gear I secured to a shaft I40 upon which is also carried a cam I5I which cooperates with the aforementioned follower I44.
The remainder of the segments I52 to I56 inclusive, of ring I36 are connectedto individual polarized relays I51 to I62 inclusive, which act as an intermediate storage means for providing an overlap, as explained hereinafter, between an incomingv signals and the mechanism of the perforating device described hereinafter. The armature I53 of each storage relay I51 to I62 cooperates with a negative potential contact point I64 and is connected to one terminal of a selecting magnet I65, the other terminal of which communicates 'with positive potential. Each magnet I65 controls an individual selecting member I66, the several of which are pivoted on a common shaft I51. 'As illustrated in the draw- 40 ings, the selecting members I65 and their associated magnets I65 are located one in back of the other for purposes of clearness, but it is to be understood that these elements in the operative structure are in alignment as are also their asso- .clated levers I53.
frictionally driven shaft I15 and is adapted to cooperate'with the projection I13 for imparting vertical reciprocati've motion to the table I12. A stop-arm I15 is also secured to shaft I15 and its adapted to be engaged by a tooth I11' formed upon an armature I15. g
Th tabl I12 in receiving its motion from cam- I14 imparts a similar movement to'the several interpositionbars I53 above which are located a set of six punches I13 which form part of the punch die assembly as in the case of the per 5 forator of P 8. 1. In operation, certain magnets I55 are cyclically-energized while the-remainder of themremain deenergized in accordance with the particular code combination that is being recorded; Springs III of members I being more powerful than those in oilevers i66 over? come the tendencies ofthe latter during the de-, energized condition oi! magnets I65, causing the levers to assume the solid line positions as. illustrated, but when. on'the contrary, the magnets combinations of a signal, members I66 are withdrawn against the tendencies of the springs I 6|, permitting levers I66 to assume their dotted line positions under the influence of their individual springs I62. The condition of the several storage relays I51 to I62 is transmitted to the operating magnets I65 and is simultaneously translated into corresponding positions of the members I66 and thereafter to levers I66 and bars I69.-
After each signal is thus translated, an operating pulse is received by a magnet I63 which thereupon attracts its armature I16 releasing stop member I16 which travels in a counterclockwise direction through one revolution thrusting table I12 and bars I69 upwardly and amxingv a set of perforations in accordance with the positions of the several bars I69. The start pulse which energizes magnet I66 is received over a conductor I64 from the positive source of current I65 through the periodic intervention of a contactor I66 controlled by a cam I61, which is also secured to driving shaft I46;
It will be understood, of course, that the proper means represented by sprocket I66 are provided for intermittently advancing the tape I69 as eac alignment of perforations is installed. a
As in the case of Fig. l, the gear ratio between shafts I49 and I46 is such that the latter rotates one complete revolution for each one-seventh of a revolution of the former. During the seventh revolution of the distributor shaft I46 when the cam III is making its final one-seventh of a revolution, the apex of cam I 6I encounters the cam .follower I9I, raising the latter into contactual engagement with a negative source of current, thereby completing the circuit for the sixth magnet I92 over conductor I93. This magnet controls a sixth perforat punch which installs the sixth perforation 96 in the .same maner as described in connection with Fig. 1, and for the same purpose. The tape perforated by this mechanism is accordingly an exact reproduction of the tape at the transmitting station, all of the signals being electrically relayed from the latter except the last described sixth perforation 96, the making of which is entirely controlled by apparatus local to the perforation station, Fig. 2.
In the operation of the present device, as a set of five permutation impulses are received over line I26, they are distributed to the five relays I61 to I62 by the distributor I66 during one of' its cycles of rotation. ,Relays I61 to I62 being of the polar type, retain the storage signal momentaril'y and until :a .subsequent and different set of signals are received. The stored signals are then relayed to the five operating magnets I66 which cause a corresponding distribution of the several members I66. At thistime, armature I16 is retracted by its magnet I66 in accordance with a signal and permits the free rotation of shaft I16 while also withdrawing its detent edge I94 from the cooperating portions of levers I66. Levers I66 thereupon are permitted .to assume positions corresponding to their respective members I66 after which armature I16 is again res leased, detaining the several levers in their assumed positions and permittingthe members I 66 to receive a new signal. Thus an overlap of operation is afforded as between the members I66 and the'interposition bars I66 so that a new.
signal is stored while the previous signal is being perforated.
