An intermediate set of keylevers |5 relates to the integer price characters and right hand keylevers IS, the fractions price characters. A fourth class of keylevers H, which have been segregated from the others in the illustration, relates to the range or qualifying characteristics of a quotation. of the three first described classes of keylevers each is provided with a bail similar to the bail l2 with the item keylevers while the several classes are pivotally carried on a common pivot'rod I8. Each bail has individual to it an insulating block I9 adapted to engage a contact spring 2| when it is rocked about its pivot |3 upon the depression of one of its associated keylevers.

As illustrated, the'groups of keylevers i5 and I5 are pivoted on a common shaft 8 and are provided with a spacing comb (not shown) while each lever is connected to an individual return spring 22 for maintaining in and returning it to its elevated position. The range keylevers I! may, if desired, be likewise supported on the rod |8 though, as will be seen in the course of the following description, their relative position with respect to the remainder of the keylevers is optional.

Below the aligned keylevers l5 and I6 are supported a set of five permutation or code bars 23, which are provided with variously located inclined surfaces 24. Of the five code bars 23 the foremost one 20 is cut away as at 26 in the region directly below the units, and fractions keylevers l5 and I6, while in the region below the items designation keylevers II it is provided with the conventional inclined notches 24 with which the remainder of the code bars 23 are provided throughout. The various inclined surfaces of the five bars 23 are each individually arranged with respect to its bar so that the depression of any one keylever of each set engaging the respective code bars 23 thrusts them rightwardly or leftwardly as the case may be into a definite and particular relationship each to the other.

Since each code bar 23 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 ll presents the five code bars permutatively into a position individual to the particular keylever, while the depression of either the units or fractions keylevers, similarly, effects but four of the five bars 23, the other one 20 being cut away as above described, so as not to be effected 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 inclistinction is taken care of by other means provided for distinguishing between one class of keylevers and another.

A sixth code bar 30 generally similar to the five bars 23 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 I5 are all inclined in one direction while those which are located beneath the fractions keylevers it are inclined in the other direction, so that the depression of a keylever I or E5 moves this lever rightwardly while the depression of a keylever it; moves it leftwardly. This bar 30 will be identified hereinafter as the sixth hole code bar, and its function is to cause the perforation of a sixth hole 90, 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 23 and 30 at its left end is articulated as at 21 to a vertically disposed lever 28, while the several levers 28 are pivoted on a common shaft 29.. At their upper ends, levers 28 are each connected to one end of an interposition bar 3| individual thereto, the opposite end of which is provided with a shouldered portion 32. Below the interposition bars 3| is a table 33 having two projecting arms 34 and 35 pivoted at 36. A solenoid 31 disposed below the table 33 has associated with it an armature 38 which is pivotally connected to the table 33 and is adapted, upon the solenoid being energized, to move upwardly rocking the table 33 clockwise about its pivot 36.

Located above the interposition bars 3| is a set of punches 39 supported in a block 4| and adapted to cooperate with a die member 42.

When a particular code bar 23 or the sixth code bar 30 is in its left handposition, as viewed in Fig. 1, through its connection with a lever 28, it presents the shoulder portion 32 of its interposition bar 3| directly beneath one of the punches 39, but when, on the contrary, it is in its right hand position the shouldered portion 32 of its corresponding interpositionbar 3| is not thus presented, but instead clears its associated punch, so that when thereafter the table 33 is recipro-' cated, those punches 39 whose associated shoulders 32 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 fail to engage their punches permitting the latter to remain down and out of cooperative engagement with the aforesaid die block.

In addition to the six aligned punches 39 aforementioned, there is another punch intermediately disposed, and adapted to perforate a somewhat smaller hole 43, as illustrated upon the fragment of tape 44, by means of which the prepared tape or form is advanced both in this and other apparatuses. In accordance with the present illustration, the central perforations 43, which will be referred to hereinafter as the feed perforations, are engaged by a feed sprocket 45 carried upon a shaft 46 suitably supported in the framework (not shown). The feed sprocket 45 is rotatably advanced one tooth step at a time concurrently with the reciprocation of table 33 in the following manner.

A bracket 41 is secured to the table 33 and is pivotally connected at 48 to one arm of a lever 49 pivotally secured at 5| so that as the projection 41 reciprocates vertically together with table 33 the former is oscillated concordantly. Upon its clockwise movement, lever 49 carrying a spring loaded pawl 52 thrusts the latter rightwardly, 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.

Also mounted on shaft 46 is a gear wheel 54 which engages and drives a pinion 55 carried upon a cam shaft 56. On shaft 56 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 59. The driving ratio between pinion 55 and gear 54 is such that for each complete revolution of shaft 56 ratchet wheel 53 and its assembly advance seven radial steps.

The energization of solenoid 31 is coincident with the depression of any of the keylevers II, I 5 or I6 by reason of the following circuit arrangement. One terminal of the winding of solenoid 3'! is connected to a positive source of current 6! and its other terminal is connected over circuit 62 to one blade each of the seven radially disposed contact switches lit to 59 inclusive. f the several switches, switches 63, lid and 65 are parallelly connected with the item keylevers it; switches 36, ill and lit, with the digits lreylevers it; while switch 69 is connected vith the fractions lreylevers M5. The several contacts to 69 inclusive and cam constitute sequence switch so which is operated progres sively in a clockwise direction. I

In its normal position apex engages the flexible blade of switch closing the circuit one of the item lzeylevers Ell. Upon depressing one of the keys ii the item hail l2 engages its contact spring ill, closing the circuit at contact points it and completing a circuit from 1% potential at 66 through the winding of solenoid l over line d2, through the closed switch the sequence switch 59, thence over line "63, con tact points i l to negative potential at E2. energizes the solenoid 3'5, reciprocating taloi ich thereupon performs a 'periorating ope tion, and advances the ratchet wheel 53 one too distance, while at the same time rotating c one seventh of its revolution so its 58 engages switch ti l, which latter also relates to the character keylevers M.

wit for its respective class lre of the keylevers ll has assoc a locking relay so that, depending upon which. the ireylevers open, high, low or last is depressed, a corresponding relay to 8G is rgized and held in locked position. through a locking circuit 82 and locking armature E33 especially provided therefor. The circuit is traceable from negative potential L 13 over line 8 through armature line 82, one of the CO2:- tacts 85 and its associated armature through the winding of its particular rela W to ill to positive potential til. Armature 83 is controlled my a magnet 88 energized through a pair of contact points 8% disposed in the path of apex oi the sequence switch 59 towards the end of its rotary cycle. Upon the energization of relay 88 armature 83 is attracted, breaking the locking ct pc is as to and is rilethe circuit and releasing the four relays 'l! to 8| which are then in readiness to store the qualitying signal of a subsequent quotation.

Thus it will be understood that the presence or absence of a fifth perforation 80, 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 last. i

It will be understood 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 conjunctively 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 four signals.

In order to control the range qualifications of a signal in accordance with the present illus= tration, four possibilities are necessary. Employing each of the four positions individually is one mode of controlling this qualification sys tern and is method employed in accordance with the 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 mechanism disclosed in l illustrates a perforated tape it as being the sole resultant oi the keyboard device it will he under-= stood, of course, that the several signals may instead of or in addition to being restored also he sent out on a communication line. By pro viding a set of cont-acts with the code cars a and 2&3 and a transmitting distributor of any conventional type electrical signals corresponding to those afilxed to the tape M may he transmitted to a remote station.

in accordance with certain systems of trans mission, complete quotation messages introoiuceol by a changed start pulse for purposes of synchronizing quotation message cycles. To accommodate systems oi this class a sxth perfora tion is provided with the final or fraction row oi perforations as illustrated in Fig. eiiect of synchronizing perforation con the mechanism of a receiving station is ly cle scribed in connection with Fig. 3 of the parent application referred to above.

In manipulating a keyboard perforate" the one just described, the operator in duce the qualifying signals cei'ore -g those lceylevers simultaneously with which the qualifying signals are installed upon the record. it is optional whether these signals he introduced before, interniediately with, or after the primary selecting of items characteristics, out in order to assure a regularity of a habit, the qualifying signals should he introduced at a definite and regular sequence during the transmission of each quotation.

Assuming that the operator desires to record a quotation ATE155 /4, which quotation happens to be the high quotation of the day, the high ireylever ii is depressed, closing the contacts 99 and energizing the high" relay l8 over the following circuit. From positive potential 81 through winding of relay "I8, over line 92, contacts 9|, to negative potential 83. The energization of relay such as '59 as follows.

I8 attracts its locking armature 86 as well as its control armature 93 maintaining the latter closed and preparing a circuit for the sequence switch From positive potential 97 through the winding of range magnet I6, over line 96, contacts 95 of switch 81 (which are still open), line 94, armature 93, and line 84 to negative potential 83. Relay I8 is held locked by reason of the following locking circuit; positive potential 81, winding of relay 1B, locking armature 86, looking circuit 82, armature 83, through line 84 to negative potential 83.

In this manner the signal is stored in relay I8 awaiting the progress of sequence switch 59 when its apex 58 arrives opposite switch 61 at which time the prepared circuit is closed, energizing the range magnet 75. This attracts armature 70 which in turn moves the fifth bar 20 leftwardly, causing to be presented the shoulder portion 32 of its associated interposition bar 3| into its punch effective position When, thereafter, solenoid 31 is energized for effecting the punch operation an additional perforation is made. As illustrated in Fig. 4 this perforation 83, in accordance with the present system, may appear in any of four positions, thereby determining the range of the associated message.

In Fig. 2, there is illustrated 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 to obviate detailed description of duplicated structures.

In this case the sequence switch 59 controls a set of contacts 63 through 69 and 89 similar to that illustrated in the preferred form, except that these contacts control a set of individual latches IOI which mechanically restrain each group of key-levers, permitting them to be operated only in accordance with the first described sequence of operation. 1

These latches IOI include hook portions which are adapted tov engage cooperating lugs I02 integrally formed with each key-lever I1, in the case of the range keylevers, and bails I2 in the case of the quotation signalling keylevers II, I5, and I6. The latch members IOI are normally spring urged to engage their overlying lugs I02 except during such times that their particular unlocking magnets are energized through the progressive operation of equence switch 59. An unjointly operative sets of contacts I04 and I05,

the latter of which are multiplied over a circuit I06 extending frompositive potential I01, over a relay I08, thence through the circuit I06, contacts I I5, circuit I09 to the contacts 63, 64 and B5 of the sequence switch 59. A source of negative potential I I I is distributed. around switch 59 over a circuit II2 communicating with each of the contacts 03 to 09 as well as switch II 3 of an unlocking circuit U4. By the normally closed condition of contact 63 negative potential is supplied to circuit I09 and upon depressing any of the range keylevers I1 is extends; through contacts I05 to the relay I08.

Upon thus being energized, relay I08 attracts its three armatures II 5, H6 and II! achieving the following results. Armature I I5 contacts with its associated point completing the locking circuit for magnet I08 from positive potential I01, winding cf relay I 03, armature H5, conductor H8, armature H9, to negative potential at I2I. Armature II6 breaks its contact with its asso ciated point removing negative potential from the range unlatching magnet I03 and permitting the latches IOI of the range keylevers IT to become effective in restraining the further operation of the range keylevers. Armature I I1 makes contact with its associated point introducing negative potential from over line I09 to the items unlatching magnet I22, thereby withdrawing the latches IOI from all of the items keylevers II.

Thus by depressing any of the keylevers I1 and closing a contact I05, an operator prepares the items keylevers for operation while also preventing the further operation of any of the range of any one or more of them disables the further operation of any others.

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 I04 simultaneously with the closure of contacts I05 causes a locking of its associated storage magnet.

It will be understood, of course, that though one kcylever only of each class II, I5, and I6 is illustrated, that this is merely for simplification of the drawings and that each is representative of a set similar to the one illustrated in Fig. 1.

As distinguished from the preferred embodiment, however, each set of keylevers I I, I 5, or I5 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 connectcd with one of the contacts of the sequence switch 59 (except item magnet I22) so that where in the first case the sequence switch merely prepared the circuits for eflectuating the keylevers II, I5, and I6, in the instant case the corresponding contacts of the sequence switch 59 unlock the latches IOI permitting the representative classes of keylevers mechanical freedom for operation.

It is to be understood that a set of code bars 55 are provided with the several keylevers just as are illustrated in Fig. 1, though they are not shown in this figure and also that a tape feed mechanism and scquence switch stepping arrangement forms part of the present structure which is operative in the same manner as the preferred form.

Operating solenoid 31 is in this case, however, directly controlled by the several multipled contacts II which in turn are under control of the universal bails I2. The circuit for energizing the winding of solenoid 31 is quite obviousand 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 II is i1 this case mechanically dependent upon the operative condition of the several classes of keylevers for 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 I08 upon the depression of any 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 ll before the item keylevers I I are yieldable to manipulation.

In manipulation, the modified form of Fig. 2 respond similarly to the preferred embodiment of Fig. 1 described above, except for the following difierences. The sequence of operation of the various sets of keylevers II, I5, 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 depression is irregular, whereas in the preferred embodiment, the keglevers were at all times depressible but were effective only in their proper sequence.

The additional pair of contacts II8 peculiar to this embodiment which are located in the path of apex 58 during the final portion of its cyclic movement are provided for the purpose of energizing an unlocking magnet I21 which restores relay I08 to normalcy in preparation for a subsequent cycle of operation. .This magnet influences an armature II9 which forms part of the locking circuit N8 of relay I08.

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 such as is adapted to accomplish this object and which may be controlled by transmitting mechanisms of the'kind described in the co-pending application referred to above, and which is capable of reproducing a control form similar to the form locally prepared by the transmitting perforator.

A signalling line I28 extends from the transmitting station and is connected to a polarized relay I29 having an armature I36 operable between negative and positive sources of current I32 and I33 connected to a solid ring E34 of a distributor I35. Distributor I35 also comprises a segmented ring I36 and a rotatable brush holder I31, the brushes I38 of which bridge the aforementioned rings I34 and I36. Brush holder I31 which is carried upon a shaft H40 frictionally driven from a suitable source (not shown) is normally withheld from rotation by an armature latch I39 pivoted at MI and under the control of magnet I42. The winding of magnet I42 is connected at one terminal with the start segment I43 of distributor I35 and at its other terminal to an electrical contacting follower I44 reciprocable between a pair of contacts I45 and I46 which communicate with negative and positive potential respectively. Shaft I40 also carries a pinion I41 which drives a gear I48 secured to a shaft I49 upon which is also carried a cam I5I which cooperates with the aforementioned follower I44.

The remainder of the segements 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 incoming signals and the mechanism of the perforating device described hereinafter. The

armature I63 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 I61. As illustrated in the drawings, the selecting members I66 and their associated magnets I65 are located one in back of the other for purposes of cleamess, but it is 'to be understood that these elements in the operative structure are in alignment as are also their associated levers I68.

In cooperation with each member I66 is a detented lever I68 capable of assuming two positions as illustrated in solid and broken lines. Each lever I68 isarticulated to an interposition bar I69 generally similar to the bars 3I of Fig. 1, while below the several bars I69 and pivoted at I1I is a table I12 having integrally formed therewith a projection I13. A cam I14 is secured to a. friotionally driven shaft I15 and is adapted to cooperate with the projection I13 for imparting vertical reciprocative motion to the table I12. A stop arm I16 is also secured to shaft I15 and is adapted to be engaged by a tooth I11 formed upon an armature I18.

The table I12 in receiving its motion from cam I14 imparts a similar movement to the several interposition bars I69 above which are located a set of six punches I19 which form part of the punch die assembly as in the case of the perforator of Fig. 1. In operation, certain magnets I65 are cyclically energized while the remainder of them remain deenergized in accordance with the particular code combination that is being recorded. Springs I8I of members I66 being more powerful than those I82 of levers I68 overcome the tendencies of the latter during the deenergized condition of magnets I65, causing the levers to assume the solid line positions as illustrated, but when, on the contrary, the magnets I65 are energized in accordance with the code combinations of a signal, members I66 are withdrawn against the tendencies of the springs I8I, permitting levers I68 to assume their dotted line positions under the influence of their individual springs I82. The condition of the several storage relays I51 to I62 is transmitted to the oper ating magnets I 65 and is simultaneously translated into corresponding positions of the mem-- bers I66 and thereafter to levers I68 and bars I69. After each signal is thus translated, an operating pulse is received by a magnet I83 which thereupon attracts its armature I18 releasing stop member I16 which travels in a counter-clockwise direction through one revolution thrusting table I12 and bars I69 upwardly and aflixing a set of perforations in accordance with the positions of the several bars I69. The start pulse which energizes magnet I83 is received over a conductor I84 from the positive source of current I85 through the periodic intervention of a contactor I86 controlled by a cam I81, which is also secured to driving shaft I40.

It will be understood, of course, that the proper means represented by sprocket I88 are provided for intermittently advancing the tape I69 as each alignment of perforations is installed.

As in the case of Fig. 1,. the gear ratio between shafts I49 and I40 is such that the latter rotates one complete revolution for each oneseventh of a revolution of the former. During several members. I66.

the seventh revolution of the distributor shaft I40 when the cam I5I is making its final. oneseventh of a revolution, the apex of cam [5| 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 perforating punch which installs the sixth perforation 90 in the same manner 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 90, 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 I28, they are distributed to the five relays I51 to I62 by the distributor I35 during one of its cycles of rotation. Relays I51 to I62 being of the polar type, retain the storage signal momentarily and until a subsequent and different set of signals are received. The stored signals are they relayed to the five operating magnets I65 which cause a corresponding distribution of the I At this time, armature I18 is retracted by its magnet I83 in accordance with a signal and permits the free rotation of shaft I15 while also withdrawing its detent edge I94 from the cooperating portions of levers I68. Levers I68 thereupon are permitted to assume positions corresponding to their respective members I66 after which armature H8 is again'released, detaining the several levers in their assumed positions and permitting the members I66 to receive a new signal. Thus an overlap of operation is afforded as between the members I66 and theinterposition bars I69 so that a new signal is stored while the previous signal is being perforated.

After shaft I 40 has completed six revolutions and is in the midst of its seventh revolution, the apex of cam I 5| encounters the follower I9I, establishing a circuit for the sixth magnet I92 which thereupon causes the perforation of the sixth hole as already explained.

.It will be understood that numerous modifications and variations of the present invention may be made without departing from the scope or spirit thereof.
