46 Claims.

This invention relates to printing telegraph systems and apparatus and particularly to apparatus for printing message material in tabular form.

An object of the invention is to provide for continuous movement of a character spacing carriage to printing positions which are selectable according to identification portions of message items.

Another object of the invention is to translate six unit permutation code signals into five unit code signals and interject function code combinations required by the tabulating printer but not contemplated by the six unit code signals.

The invention features a signal storing and translating mechanism by means of which a plurality of code combinations pertaining to the identification of a printing position are stored and are translated into a single code combination by which the printing position is selected. 7

For illustrative purposes, the invention has been shown as applied to the printing of stock quotations in columns upon page width record material, each column being assigned to a particular stock. The stock quotations are transmitted from a six unit code telegraph transmitter and are distributed by a receiving distributor to a primary set of signal storage relays. A switching mechanism associated with the primary storage relays transfers the signal combination to sets of relays in either of two secondary signal storage devices. One of the secondary storage devices is controlled to store signal combinations representing letters, and this device may have as many sets of code combination storage relays as the maximum number of letters in any stock designation for which prices are to be recorded. The other secondary storage device has sets of storage relays for storing the figures signal combinations representing a stock price to be recorded and may have as many sets of signal storage relays as the maximum number of digital positions that may be encountered'in stock prices. In the particular embodiment of the invention shown and described, there are three sets of letter storage relays and three sets of price figure storage relays, but it will be understood that one or more sets of storage relays may be added to either of the secondary signal storage devices, as required.

The switching mechanism associated with the primary signal storage device transfers letter signal combinations to the first, the second, and then the third set of storage relays in the secondary storage device for letters. It transfers figure signal combinations to the first, the second, and then the third set of figure storage relays in the secondary storage device for figures.

The secondary storage relays for letter signals have many contact tongues which the relays operate. These contact tongues may be considered as falling into groups, the corresponding tongues of all of the relays comprising one group. Each tongue is connected to the fixed contact of the adjacent corresponding relay tongue, and the tongues are so arranged to make or break contact, that for a particular combination of letter signals stored in the letter storage relays an electrical circuit is completed through all of the contact tongues and fixed contacts in the group, while for any other combination of letter signals in storage, the chain of contacts and tongues is interrupted at one or more points. Each group of contact tongues is difierently coded so that not more than one chain contact circuit may be completed by any combination of letter signals in storage, and when stock identification letter combinations are stored for which the recording of prices is not desired, no chain contact circuit will be completed.

Each chain contact circuit includes a relay which has, aside from certain control contact tongues, five contact tongues to engage one or more fixed contacts arranged in position and number according to a single five unit permutation code combination. The permutational arrangement of fixed contacts in each chaincontact controlled relay differs from the arrange ment of fixed contacts in all of the other similar relays, and the fixed contacts of each such relays are arranged to control permutably five punch interponent controllingv magnets in a multiple code perforator which may be similar to that disclosed in Patent 2,085,120 granted June 29, 1937, to L. M. Potts.

The sets of relays in the secondary storage device for figures control corresponding sets of punch interponent magnets in the multiple perforator. With the arrangement thus far described, one code. combination representing a stock quotation designation and several code combinations representing the figures of a stock price may be stored in the sets of magnets in the multiple perforator. The perforator includes other sets of interponent controlling magnets that are permanently coded to represent and control the perforation of particular function signals, such as letter shift, figure shift, carriage return, and line feed. After the last figure signal combination of a stock price that is to be recorded has been stored in the multiple perforator, the punch mechanism may be operated to efiect the simultaneous perforation of all of the code combinations stored in the perforator.

From the tape perforator, the tape is fed into a tape sensing transmitter device in which the several code combinations perforated simultaneously in the multiple perforator are sent successively and are transmitted to a receiving printer. The spacing carriage of the receiving printer is provided with contact brushes which traverse a continuous conductive bar and a row of segments, as the carriage travels from beginning to endof-line position. The segments are connected together electrically in groups, all of the .contact segments are normally included in an electrical circuit which may be completed by the brushes supported b the carriage, but when a code combination is sent by the tape sensing transmitter which pertains to a printing position at which a stock price is to be printed, the contact segments associated with that position are isolated so that current will not traverse the brushes when they come into engagement with those segments. When a quotation is to be printed, the spacing carriage is set in motion and moves continuously as long as its brushes engage contact segments which have not been isolated from the electrical circuit. As soon as the brushes engage isolated contact segments, the carriage is arrested and the printing of the stock price at that position proceeds. Between the printing of one stool; price, and the next received price, whether it pertains to the same stock or to a different stock, thespacing carriage is restored to its beginningofline position, andthe line feed mechanism of the printer is operated. The page record which will be obtained from this printer will comprise columns Of stockprices, each column containing prices relating only to a single stock, and all quotations pertaining to stocks, the quotations of which were not to be printed having been discarded ahead of the multiple perforator.

For a more complete understanding of the invention, reference may be had to the following detailed description to be interpreted in the light of the accompanying drawings in which,

Referring now to the drawings, and particularly to Fig. 1, the reference numeral indicates generally a printing telegraph station including transmitting contact l2 and home recorder control magnet I3, connected in series between grounded line battery I4 and telegraph line it. At its remote end, telegraph line I6 is connected to a line relay IT, which has its contact tongue I8 operable between marking contact l9 and spacing contact 2|. Tongue I8 is grounded and contacts I9 and 2| are connected to continuous conductive rings 22 and 23, respectively, of a receiving distributor indicated generally as 24. Included in distributor 24 are segmented rings 26 and 21, the former having a plurality of electrically isolated segments, one of which is designated 28, and the remaining five being designated 29, and the ring 21 being electrically continuous, except for electrically isolated segment 3|.

Distributor 24 has revolving brush arm 32 which carries a pair of electrically connected brushes 33 and a pair of electrically connected brushes 3t, these brushes being insulated from arm 32. Brushes 33 engage distributor rings 22 and 25 and brushes 34 engage rings .23 and 21. The rotation of brush arm 32 is controlled by a stop lever 35 which serves as the armature for a magnet 37, the operating circuit of which extends from grounded battery 38, through the winding of magnet 31, electrically continuous portion of distributor ring 21, brushes 34, ring 23, line relay spacing contact 2|, and grounded relay tongue l8 when the tongue is in spacin position. Thus, when transmitter I2 is in the rest position, and holds line relay H in the marking condition, the circuit of magnet 31 is open at spacing contact 2|, magnet 3'! is de-energized, and stop lever 36 engages brush arm 32 and holds the brushes stationary. Upon the starting of transmitter I2, line It is opened to establish the start pulse condition, which is spacing, line relay i1 is derenergized, the circuit of magnet 31 is completed at contact 2|, stop lever 36 i attracted, and brush arm 32 is released for rotation.

Segment 28 of distributor 'ring 26 is connected by conductor 39 in cable 40 to one end of the operating winding of relay 4|, the other end of which is connected by conductor 42 togrounded battery 43. Each of the segments 29 of distributor ring 26 is connected by an individual conductor in cable 40 to one end of the operating winding of an individual relay 44 of the primary set ofstorage relays G5, there being five of the relays 44. The other ends of the operating windings of relays M are connected to battery 43 by conductor 42. Relay has a holding winding, one end of which is connected to battery conductor 42, and the other end of which is connected to the innermost contact of relay ll which is a make contact. The tongue which co-operates with this contact is connected by conductor to the single break contact of relay 4?, the tongue of which is grounded. One end of the winding of relay 4? is connected to battery 48, and the other end is connected to isolated segment 3| of distributor ring 2?. Each of the relays 44 has a holding winding, one end of which is connected to battery conductor 42, and the other end of which is connected to the innermost contact of the respective relays M. The inner contact tongue of each of the relays 44 is connected by conductor 45 to one contact spring of normally closed cam controlled contacts 5|, the other of which is grounded.

The speed of rotation of brush arm 32 is synchronized with the speed of transmission of telegraph signal impulses fromtransmitter I 2 so that following the release of the brush arm 32, as line relay I! responds to the start impulse, the segment 28, and. the segments 29, are traversed in unit permutation code, the first five selecting impulses of which determine the character to be printed and the sixth impulse of which determines whether the character will be a letter or a figure, it being understood that for stock quotation purposes some letters and marks of punctuation are selected as if they were figures. It has been found desirable in the present system to transmit the letter or figure shift impulse ahead of the five character selecting impulses. Therefore, the segment 28 is traversed by brushes 33 ahead of the segments 29 and shift signal storage magnet M is controlled ahead of storage magnets 44.

The innermost contact tongue of relay 4! is engageable, upon energization of the relay, with a fixed contact which is connected to the holding winding of relay M the other end of the winding being connected to battery conductor 42. In order for relay M to be held when it becomes energized, ground must be applied to its innermost contact tongue through conductor 46, which necessitates that-relay G! shall be in de-energized condition. It will be noted that line relay l1 applies ground through segment 3! of distributor ring 21 when the shift controlling pulseis spacing and. applies ground to segment 28 of distributor ring 26 when the shift controlling pulse is marking. Segment 3| is connected to relay 41' by conductor 52, so that the circuit of relay 4! is completed and the relay is energized when the shift controlling pulse is of spacing nature, the holding circuit of storage relay 4! being interrupted by attraction by relay 4? of its armature. However, when the shift controlling pulse is of marking nature, the energizing circuit of relay 4! is completed by the application of ground to segment 28, and relay 4! becomes energized and attracts its contact tongues which are held due to energization of the holding winding, the relay 4'! being then in de-energized condition.

Each of the storage relays 4 has a contact tongue in addition to its holding contact tongue which is connected to one of five conductors in a cable 53. Fixed contacts with which these contact tongues are engaged upon'energization of any of the relays M are connected by concluctor 54 to one of a pair of normally open cam controlled contacts 56, the other of which is con nected to ground. Marking impulses are represented by energized condition of the relays M and spacing impulses are represented by d e-energized condition of the relays. I r 7 Signal combinations stored in the primary storage device 45 are transferred to the secondary storage devices through a counting relay mechanism indicated generally by the reference numeral 51." The counting device 5'! includes letter signal counting relays 53, 59 and BI and figure signal counting relays 62. 66 and 6d. Relay 58 has five contact tongues 65 that are engageable, upon energization of the relay, with fixed contacts individually connected to five conductors contained in a cable 5?. Relay 59 has five contact tongues 68 which, upon energization of the relay, engage five fixed contacts individually connected to conductors in a cable 69. Contact tongues 68 are engageable, when relay 59 is deenergized, with five fixed contacts individually connected to the contact tongues 66 of relay 58. Relay 6| has five contact tongues H which engage fixed contacts connected to the tongues 68, when relay 6| is de-energized, and which engage fixed contacts individually connected to five conductors in cable 12 when relay 6| is energized.

Relays 62, 63 and 64, which control the counting of figure signals, are provided with sets of five contact tongues 13, M and '16, respectively, which, upon energization of their respective relays, engage fixed contacts individually connected to conductors in cables l1, l8 and 19, respectively. The fixed contacts, which contact tongues 16 engage when relay 64 is in de-energized condition, are connected to the contact tongues 14 of relay 63 and the fixed contacts which these contact tongues engagewhen relay 63 is in deenergized condition are connected to the contact tongues 73 of relay 62, which is the first figure counting relay and which has the fixed contacts engaged by its contact tongues 13 when in deenergized condition connected to contact tongues H of the last letter signal switching relay 8i. From the foregoing, it will be apparent that when all of the relays 58 to 64, inclusive, are de-energized, the contact tongues 66 of the first letter signals switching relay 58 are connected to the tongues E5 of the relay 64 through the contact tongues and back contacts of the intervening relays 59 to 63, inclusive. The conductors in cable 53 are individually connected to the contact tongues 16 so that in the rest condition of the apparatus. these conductors are connected directly to the contact tongues 66 and will, upon energization of relay 5%, become connected to the individual conductors of cable 61.

One end of the winding of each of the relays 58 to 64, inclusive, is connected to a battery conductor 8! to which is connected one end of a battery 82, the other end of the battery being grounded. The other end of the winding of relay 58 is connected to one end of the winding of a pilot relay 83 and to a fixed contact which is engaged by the contact tongue of relay 8:: when the relay is de-energized. The other end of the winding of relay 83 is connected to a fixed holding contact of relay 5B which is engaged by the innermost contact tongue when relay 58 is energized. The holding contact tongue of relay 58 is connected by conductor 84 to the single contact tongue of a, release relay 86. When relay 85 is de-energized, its contact tongue engages a fixed contact which is connected to ground. The enerizing circuit for relay 58 extends from grounded battery 82 through conductor 8|, winding of relay 53, back contact and contact tongue of relay 83, thence through conductor 81, back contact and outer contact tongue of relay 88, and normally open cam controlled contacts 89 to ground. When relay 58 becomes energized over the cir-- cuits just described, it attracts its holding contact tongue which places relay 83 in series with relay 58 and establishes a holding circuit for the two relays from the grounded contact engaged by the contact tongue of relay 86 through conductor 84, thus replacing the ground supplied by cam controlled contacts 89, the relay 83 pulling up upon removal of the short circuit to ground at contacts 89. Upon the energization of relay 83, itscontact tongue is attracted to disconnect conductor 8'? from the back contact of relay 83 and to connect it to the front contact of the relay which is connected totlie contact'tongue of a relay 9| which bears the same relation to relay 59 that relay iit bears to relay 58.

Relay 9| has a back contact which is connected to the winding of relay 59 and which is engaged by the contact tongue of pilot relay 9! to provide an energizing circuit for relay 59 from battery 32 through conductor 8|, winding of relay 59, back contact and contact tongue of relay 9|, front contact and contact tongue of relay 83, conductor 81, back contact and outer contact tongue of relay 88, and normally open cam operated contacts 89 where ground connection is applied when the contacts are closed. When relay 59 is energized, it attracts its holding contact tongue which applies ground from the contacts of relay 8% through conductor 84, and places relay 9| in series with relay 59, the relay 9| thereby becoming energized. Upon the energization of relay 9| its contact tongue is attracted, thereby opening the original energizing circuit for relay 59 and preparing a circuit for the energization of relay 5| because of the fact that the contact which the tongue of relay 9| engages, when the relay becomes energized, is connected to the contact tongue of a relay 92 related to the relay 6| in the same manner that relays 83 and 9| are related to relays 59 and 59, respectively. Relay 92 has no front contact to be engaged by its contact tongue, because it is not required to prepare an energizing circuit for another relay, the associated relay 5i being the last of the three letter signal counting relays.

The figure signal counting relays 62, B3, and 64 have associated with them the pilot relays 93, 94

and 96. respectively, the relay 93 being arranged to establish an energizing circuit for the relay t3, the relay 94 being arranged to establish an energizing circuit for the relay 94, and the relay 96 being arranged merely to interrupt the energizing circuit for the relay 64 when the holding circuit for that relay has been established through its innermost contact tongue and through relay 96 in a manner similar to the interruption of the energizing circuit of letter counting relay 6| by its pilot relay 92. It is to be noted that whereas the energizing circuits for the relays 58, 59 and Bi extend through the outer contact tongue and back contact of relay 89, the energizing circuits for relays 52, 63 and 94 extend from battery 82 through conductor 8| and include the front or make contact of relay 88 with which its outer contact tongue is engageable, from which the circuit will extend to cam controlled contacts 89 only when relay 88 is energized. From this it will be apparent that there are two sets of counting relays, the selective operation of which depends on the condition of relay 38, which, in turn, depends upon the position of the center contact tongue of relay 4 l. A counting operation started in the first set of counting relays need not be carried to the end of the set in order to switch to the operation of the second set. Such switching may be accomplished after the operation of only one or two of the relays 58, 59 and 6|, by the energization of relay 4| and the closure of contacts 89. At any time during a counting operation in the second set of counting relays, the counting operation may be terminated by de-energizing relay 4| and closing contacts I92, which will complete the energizing circuit for relay 86, which will remove ground from the holding circuits of both sets of counting relays and from relay 88, and all of these relays will be released. Counting may then be started again in the first set.

The energizing circuit for relay 88 extends from grounded battery 82 through conductor 8|, winding of relay 88, conductor 91, contact tongue 98 of relay 58, conductor 99, make contact and center contact tongue of shift and unshift signal storage relay 4| and conductor ||l| to normally open cam controlled contacts I02, one of which is grounded. It will be apparent from this that relay 88 can be energized only after relay 4| has become energized due to the reception of a signal combination in which the shift or unshift controlling pulse is marking, and further that at least one letter signal combination must have been stored in the storage relays 44 and applied to the conductors contained in cable 61 by the operation of first letter switching relay 58 so that contact tongue 98 will have engaged its contact to complete the energizing circuit for relay 83. Upon the energization of relay 83 its inner contact tongue engages a make contact from which conductor I03 extends to ground supplying conductor 84 thereby establishing a holding circuit for relay 83.

When the relay 92 has become energized and its locking circuit is completed, two contact tongues which it controls and which are involved neither in the establishment of the locking circuit nor in the switching of the signal combination engage their associated fixed contacts. One of these, designated 94, is connected by a conductor we to the back contact which the center contact tongue of relay 4| engages when the relay is deenergized. The fixed contact which contact tongue m4 engages is connected by conductor i9! to the Winding of relay 86. As long as the center contact tongue of relay 4| remains attracted, relay 86 will be in de-energized condition and the relay holding current traversing conductor 8d will continue. When relay 4| is released, which operation occurs upon the reception of a code combination pertaining to the selection of a letter and therefore having its shift or unshift controlling impulse of spacing nature, the energizing circuit for relay 86 will be prepared by engagement of the center contact tongue of relay 4| with its back contact and will be completed upon the closure of cam controlled contacts I92 to cause the attraction of the contact tongue of relay 8% and therefore the removal of ground from conductor 84. The holding circuit for the relays 58, 59, 6|, 62, 63, 64, 83, 9!, 92, 93, 94, and 96 is thus broken and these relays are released. It will be noted that since contact tongue )4 is associated With the first figure signal switching relay 92, the holding circuit for the several switching magnets will not be interrupted in response to any letters signal combination received from the transmitter IE! but will only occur in response to a letters signal combination which was preceded by at least one figures signal combination.

The other control tongue associated with relay 62 is designated by the reference numeral H13. The circuit which it prepares may be traced from battery 82 through conductors 3| and I09, winding of relay conductor H2, fixed contact with which contact tongue I99 is engageable, tongue I08, conductor H3, outermost contact tongue of relay 4i, fixed contact which it engages when relay 4| is de-energized, conductor H4, and normally open cam controlled contacts H6, one of which is connected to ground. Upon completion, at the contact E6 and by the outermost contact tongue of relay 4|, of the circuit for relay l .l 5 prepared by contact tongue |ll8 of relay 92, relay becomes energized and attracts contact tongues II! and H8. Contact tongue H1 is brought into engagement with a grounded fixed contact and contact tongue H8 is drawn out of engagement with a grounded fixed contact. Conductors H9 and I2I are connected to the contact tongues I I1 and H8 respectively, and these conductors extend to apparatus which will be identified later. The conductor I2I is also connected to one contact of a pair of normally closed cam operated contacts I22, the other of which is connected to ground.

The shaft which carries brush arm 32 has secured thereto a timing cam I26, the shaft being designated by the reference numeral I21. Shaft I21 also carries a cam sleeve I28 to which rotation may be imparted from shaft I21 through a friction clutch (not shown). Cam sleeve I23 has secured thereto a stop disc I29 and a plurality of cams for controlling the previously identified sets of cam controlled contacts. The cams, numbered in the order in which they actuate their followers, as is clearly apparent from the angular distances between the apices and their respective followers, are designated by the reference numerals I3I, I32, I33, I34, I33, and I31. Timing cam I26 is engaged by one end of a a stop lever I38, the other end of which is normally interposed in the path of a shoulder of stop disc I29. Lever I38 is biased into engagement with timing cam I26 by tension spring I39. When brush arm 32 is set in rotation by the withdrawal of stop lever 36 by magnet 31, timing cam I26 is also rotated and when its apex is presented to cam follower lever I38, lever I38 will be rocked counterclockwise to withdraw it from blocking relation with the shoulder of stop disc H29, thereby freeing cam sleeve I28 to be rotated by shaft I21. Secondary transfer cam I3I is the first to operate its follower thus closing the contacts H6 and applying ground to conductor H4 to effect the energization of relay III if contact tongue I68 of relay 62 is in engagement with its fixed contact and if the outermost contact tongue of relay M is in engagement with its back contact. If the circuit of relay I I I is open at the contact tongue I68 of relay 62 or at the outermost contact tongue of relay 4 I closure of contact I I6 by cam I3I will be an idle operation. It is to be noted that relay M is operated to attract or release its contact tongues in response to the shift or unshift impulse accompanying a code combination. Cam I3I should therefore be so timed to the rotation of brush arm 32 that the contacts H6 are closed during or after the traversal of segment 28 of distributor ring 26 by the brushes 33. The removal of the ground from conductor I2I of contact tongue II 8 of relay III does not immediately change the electrical condition. of conductor I2I because contacts I22 controlled by cam I32 are then closed. Prior to the release of contacts H6 by cam I3I, relay unlocking cam I32 opens the contacts I22 thereby disconnecting conductor I2I from ground. Relay III has no holding circuit and therefore as soon as contacts I I6 are released by cam I3I relay I I I releases its contact tongues removing the ground connection from conductor I I9 and restoring ground to conductor I 2! by contact tongue H8. The reason for the provision of two grounds for conductor I2I is that an operation is to be performed by the grounding of conductor H9 before ground is removed from conductor I2l and further so that when contacts I22 are opened by cam I32 at a time when relay III is tie-energized the ground shall not be removed from conductor I2I. Counting relay controlling cam I33 becomes effective to close contact I02 after cam I32 has. permitted contacts I22 to reclose. As previously set forth, the effectiveness of contacts I62 depends upon which positions the contact tongues of relays 4I occupy. The closure of contacts I32. when the contact tongues of relay 4I are released, results in connection of ground to conductor I06 and if contact tongue I64 of relay 62 is then engaging its fixed contact, relay 86 will be energized to remove ground from conductor 84 and thereby open the holding circuits of all of the magnets 58, 59, BI, 62, 63, 64, 83, 9|, 92, 93, 94, and 96 in switching device 51. The closure of contact I92 when the contact tongues of relay 4! are attracted results in the connection of ground to conductor 99 and therefore the energization of relay 88 which remains energized through its holding circuit and prepares an energizing circuit for the relay 62.

Pulsing cam I34 closes contacts 83 shortly after contact I02 have opened and thereby ap-; plies ground to conductor 99, the effect of which is to complete the energizing circuit for relay 58 or 62, depending upon, whether relay 88 is dev energized or energized.

Primary transfer cam I36 closes contacts 56 after contacts 89 have reopened to apply ground tothe fixed contacts that are engaged by the contact tongues of the relays 44 connected to the conductors in cable 53. Thus, ground is connected to each of the contact tongues 16 of relay 64 for which corresponding storage relays 44 are energized, and through cable 53 and the chains established by unattracted contact tongues 14, 13, II, etc., to the. lowermost attracted set of contact tongues of the switching relays and from those contact tongues to the conductors in one of the cables 61,69, 12, etc. Preferably, thecam- I36 is timed to close contacts 56 after the last selecting impulse of a signal combination has been received and applied to cable 40 by the dis-' tributor 24. Relay release cam I31 opens contacts 5| just before stop disc I29 is arrested, to remove ground from the holding circuits of the storage relays 44. The relays are thus released and conditioned for the storage of a new signal combination.

Referring now to Fig. 2 it will be observed that the five conductors contained in cable 61 are connected to the first set of five storage relays: I 4| in the secondary storage device for letters which is indicated generally by the reference. numeral I 42. Similarly the conductors in cable 69 are connected to the five relays I43 compris-x ing the second set and the conductors in cable 12 are connected to the five relays I44 comprising the third set. The ends of the windin'gsof relays I4I, I43 and I44 that are connected to the conductors contained in the cables 61, 69, and 12 are also connected to holding contacts.in dividual to the several relays I4I, I43, and 144.. A common battery. conductor I46 extends from all of the relays I M, I43, and I44 to grounded. battery-I41. Each of the secondary storage re-. lays I4I, I43, and I44 has a holding contact tongue connected to the conductor-I2I,previously identified, which normally is connected to. ground through contact tongue H8 of relay. II I and through contacts I22 (Fig. 1). The energizing circuits for relays I4I, I43, and I44. are completed from battery I41 through the relays and through their'cables 61, 69, and 12, respectively, then through the conductors in cabl e 53 when: contacts 56f'co'ritrolled by cam I36 are closed to connect ground to the primary storage contact tongues of relays M. The locking circuits for the relays IM, hi3, and I 34 are interrupted when the grounds are removed from conductor I2! at contact tongue H3 and cam operated contacts I22.

Each of the relays MI, I 13, and Hill is provided with as many additional contact tongues andfixed contacts to be engaged by the tongues as the number of columns in which message items are to be printed in tabular form. All of the tongues of the lowermost relay I44, except the locking contact tongue are connected to the conductor II 9 to which ground is connected when contact tongue H1 is attracted by relay III. The fixed contacts associated with the lowermost of the relays I ia are connected to the corresponding contact tongues of the relay I44 next above the lowermost relay. Similarly those fixed contacts are connected to the contact tongues of the next relay I I l, counting upwardly. This arrangement continues across the entire group of letter signal storage relay contact tongues and contacts, and the fixed contact associated with each of the contact tongues of the uppermost relay MI is connected to an individual code storage relay M8, all of the relays I 38 having a common battery conductor I49 which is connected to grounded battery Il'iI. In each interconnected row of contact tongues and contacts, certain of the contacts are positioned to be engaged by their contact tongues when the relays I lI, I 43, or Hi l with which they are associated are de-energized, while others of the contacts are positioned to be engaged by their contact tongues when the tongues are attracted due to energization of the associated relay. The disposition of the contacts on one side or the other of their associated contact tongues is in accordance with codes, each chain of 'contact tongues and contacts being difierently coded. Thus, with reference to a particular chain of contacts and contact tongues, when the relays MI, I63, and IN are energized according to the coding of that chainof contacts and tongues so that all of the tongues which must be attracted in order to engage their contacts are attracted, and those which normally engage their contacts have remained unattracted, a conductive path will be established from the contact tongue II1 of relay III through conductor IIQ, through the completed conductive chain and the relay I 28 associated with it, and then to the grounded battery II. Current flows in this circuit to effect the energization of the particular relay I48 when ground is connected to contact tongue II1 by the energization of relay III (Fig. l). The coding of the chains of contacts and tongues is such that only one conductive path will be completed to a relay M3 in response to any particular com bination according to which the relays I ii, M3, and I44 are energized. In this way any one of the relays I48 may be selected and operated in response to the telegraphic codes corresponding to stock designations comprising one, two or three letters. For any stocks, the quotations of which are not of interest in a particular receiving ofiice and therefore are not to be printed, no chain of contacts and tongues is provided to be completed when the relays MI, 53, and I44 are actuated according to the codes representing those stocks. Thus, no relay I 58 will be operated and the letter codes will merely remain in storage in the relays I II, I43, and IE4 until the holding circuits for these relays are interrupted by the removal of ground from conductor I2I at contact tongue H8 and cam controlled contact I22.

Each of the relays I48 is provided with a holding contact tongue I52 connected to conductor I53. Conductor I53 is connected to the fixed contact of a relay I56 which has anoperating winding and a locking winding. Both of the windings of relay I56 are connected to conductor I46 to which battery I41 is connected and the other end of the Operating Winding isconnected to conductor M6 to whichthe chain circuits controlled by relays I-Iii are connected, so that when armature II1 is attracted by relay III (Fig. 1) one of the relays I48 may be energized and relay I56 is energized through its operating winding to cause the attraction of its contact tongue I51 into engagement with its fixed contact. Contact tongue IE1 is connected by conductor I58 to one of a pair of normally closed cam operated contacts I59 the other of which is connected to ground. Upon the operation of relay I56, the holding circuit for relays I48 is completed from battery I5I through conductor I49, through the fixed contact of the operated relay I48, through its contact tongue I52, conductor I53, contact tongue I51 of relay I56, conductor I58 and normally closed contacts I59 to ground. The holding circuit for relay I56 extends from battery I41 through conductor I46, holding Winding of the relay, conductors IEI, I62, I63, and IE4 to the outermost contact tonguesof all of the relays I48 and in the case of an energized relay I48 through the fixed contact engaged by the attracted outermost contact tongue to conductor I65 which is connected to ground. From this it will be observed that the holding circuit for an operated relay I 28 includes the contact tongue E51 of relay I58 and that the holding circuit for this relay includes a contact tongue associated with each of the relays I48. It will be apparent that the opening of contacts I59 will interrupt the circuit of an operated relay I48 which will release its contact tongues thus opening the holding circuit for relay I56 which will likewise become released.

In addition to the contact tongue for its own holding circuit and the contact tongue for the holding circuit of relay I56, each of the relays I48 has five contact tongues which are connected to ground conductor I66. The sets of five contact tongues of the relays I48 are designated by the reference numeral I61 and various permutational combinations of fixed contacts are provided for the contact tongues I61, no two relays I48 having the same combinations of contacts. Corresponding code contacts of all of the relays I48 are connected to common conductors and thefive code contact conductors enter a cable I68. The cable I68 extends to punch interponent controlling magnets in a tape perforator which will be described later.

The secondary signal storage device for figures is indicated generally by the reference numeral I1I in Fig. 2 and this storage device consists of three sets of storage relays I12, I 13, and I14, each set consisting of five relays. The five conductors in cable 11 are connected individually to the windings of relays I12 and to holding contact for those relays. Similarly, the conductors contained in cable 18 are connected to the windings of relays I13 and to their holding contacts and the conductors contained in cable 19 are connected to the windings of relays I'M and to their holding contacts. Common battery conductors for the relays I12, I13, and I14are connected-to bat-I tery conductor I49, which as previously'set forth is connected to grounded battery I41. The holdin-g circuit for relays I12 extends from grounded battery I41, over conductor I46, winding of relay I12, the left-hand armature and front contact thereof, front contact and armature I51 of relay I56, conductor I58, and contact I59 to ground. The holding circuit contact tongues for the relays I13 and I14 are connected to the conductors I11 and I18 respectively, which in turn are connected to conductor I16. In addition to the locking contact tongues, the relays I12 are provided with individual code contact tongues I19 all of which are connected to the conductor I62. The relays I13 have similar code contact tongues I8| connected to a conductor I82 and the relays I14 are provided with individual code contact tongues I83 connected to conductor I84. The conductors I82 and I84 and as previously set forth, the conductor I52 are connected to conductor I63 which may be grounded through the outermost contact tongue of any storage relay I48 which may become energized. The five fixed contacts which may be engaged by the code contact tongues I19 are connected to five conductors which enter a cable I86, the five contacts that may be engaged by the code contact tongues IBI are connected to five conductors which enter a cable I81 and the five contacts which may be engaged by the code contact tongues I83 are connected to five conductors which enter a cable I88. The cables I86, I81, and I88 lead to punch interponent controlling magnets of a tape perforator which will now be described.

A tape perforator which may be similar to that shown in Patent 2,085,120, granted June 29, 1937, to L. M. Potts is indicated generally'in Fig. 2 by the reference numeral I9I. The tape perforator according to the patent has several sets of punches for simultaneously perforating several code combinations in a tape. According to the disclosure of the patent, each set of punches comprises six punches whereas in the present disclosure only five punches to a set are required, since a five unit code affords thirty-two usable combinations and even though certain of the combinations are used for selecting functions sufficient code combinations remain for selecting all of the printing column positions on a page on which stock quotations are to be printed in tabular form. There is one exception to the provision of five punches to a set, a sixth punch being required in one set, the extra punch pertaining to a special control, and not being a permutational element of a code combination. The selection or nonselection of anypunch in any group is controlled by an individual magnet and accordingly the seven banks of punch con-' trolling magnets, each bank consisting of five magnets, have been shown in Fig. 2 by way of representing the multiple code perforator I9I. Each of the magnets in the multiple code perforator I9I has one end of its winding connected to a conductor I92 to which is connected grounded battery I93. The ends of the magnets thus connected may be described as the battery ends of the windings and the other ends will be described as the ground ends.

.The first set of five magnets, identified by the reference numeral I94, have their ground ends connected to conductor I63 so that these five magnets will be energized when'the outermost contact tongue of any one of the relays I48 is attracted. The magnets I94..will ,thus control their punch inter-ponents to cause a full marking code of five perforationsto be punched by the perforating mechanism. In the operation of a permutation code printing telegraph apparatus employing a five unit code the all-marking combination which the magnets I94 will set up is generally assigned to control the letter shift function.

The magnets in the second set, identified by the reference numeral I96, have the ground ends of their windings connected to the five conductors contained in cable I68. They may thus become energized in permutational combination according to the combinations of code contacts associated with the various storage relays I98.

The magnets in the third group, designated by the reference numeral I91, have the ground ends of all but the third magnet permanently connected to'ground conductor I83. The ground end of the third magnet is left unconnected. The code combination which this set of magnets establishes pertains to the figures shift function and the signal, upon being received by a printing telegraph recorder, positions the apparatus for the printing of figures.

The magnets of the next three sets, designted I98, I99, and 29I are connected to the set of five conductors contained in the cables I 86, I 81, I98, respectively. These cables receive the figures signal storage conditions from the figures signal storage relays I12, I13, and I'M respectively and the magnets I98, I99, and 21 are energized correspondingly in permutational combination to control the perforation of corresponding signal combinations.

The last set of magnets, designated 202, is the one which has a sixth magnet, and the set has only two of its magnets connected to ground conductor I93; namely, the fourth and sixth. The remaining four magnets of the set are left unconnected on the ground side. The code combination which is perforated in response to the operation of these magnets pertains to the carriage return and line feed functions of a printing telegraph recorder and controls the advancement of the page and the restoration of the spacing carriage to the beginning of line position. The sixth magnet, and the perforation which it causes to be made in the tape do not pertain to the permutation code contemplated by the other five magnets in the group or set, but pertain to indication of the fact that the accompanying permutation code combination, namely the carriage return and line feed signal, is the last in a succession of signal combinations comprising one stock quotation group. The perforation is in the margin between the edge of the tape and an outermost longitudinal row of code perforations.

The sets of magnets I94, I91 and 292 and the sixth magnet associated with the set 202 are permanently coded and are independent of any signal combinations received and stored. They operate invariably upon each operation of the perforator to cause the function signals hereinbefore identified and the quotation end indicating signal perforation to be punched in the-tape.

Since the energization of punch controlling magnets I94, I96, I91, and 202 is controlled through contacts associated with relays I 48 which are individually locked upon being energized and since the magnets I98, I99, and 29I are energized through circuits completed by contact tongues associated with the relays I12,

I13, and I14 which also become held in energized condition, the punch controlling magnets will remain energized as long as any one of the relays I40 and combinations of the relays I12, I13, and I14 are energized.

At the time that ground is connected to conductor I63 it is simultaneously connected to conductor I84 which is connected to conductor I63. At the end of conductor I84 is connected one end of the winding. of a start magnet 203 for the perforator I9I the other end of the winding of the magnet 203 being connected to grounded battery 204. The armature 205 of start magnet 203 is in the form of a latch which may engage either of two recesses in a stop disc 201. Disc 201 holds the operating shaft 208 of perforator mechanism ISI stationary until start magnet 203 becomes energized, when it attracts armature 206 and permits disc 201 and shaft 208 to rotate through one-half revolution, whereupon shaft 208 is rearrested by armature 206, the perforation of all of the code signals pertaining to a stock quotation being performed in each half revolution of shaft 203. Following the perforation of the code signals and before the arrestment of shaft 208, the punch pins are retracted, usually by springs, and the tape is advanced a distance equal to that occupied by seven code combinations by tape feed mechanism (not shown). A contact controlling cam 259 is carried by shaft 208 and rotates with disc 20?. Cam 209 is provided with two apices and near the end of one-half revolution in the direction indicated by the arrow, and after the perforating operation has been completed, it opens the normally closed contacts I59 thereby removing ground from conductors I58, I53, I16, I11 and I18, thereby releasing all of the relays I48, I12, I13, and I14. The ground is thus removed from conductor I63 and the energizing circuits for all of the punch interponent controlling magnets and for the perforator start magnet 203 are interrupted as is also the holding circuit for relay I56.

The apparatus shown in Figs. 1 and 2 comprises a complete system for receiving stock quotations from well-known types of stock quotation transmitters, for selecting certain of the stock quotations for printing, and rejecting others, and for preparing a record storage medium containing signals pertaining to those quotations that are to be recorded, necessary function controlling signals required for the operation of a page printer being included in the record storage medium along with the stock quotation signals. The operation of this apparatus will now be described.

For the purposes of the following description, let it be assumed that all of the apparatus is in the condition shown in Figs. 1 and 2; namely, with all of the relays de-energized at the time that signals begin to be received. from transmitter I2 by line relay I1. This would not be a true operating condition, as it will be found from the description that certain stored conditions are not cleared out when the signal combinations corresponding to the stock quotation have been perforated in the tape, but remain in storage until the next stock quotation begins to be received. The assumed condition maybe that which exists when starting the apparatus at the beginning of the day. The stock quotation will be assumed to be identified by three letters, and the price will be assumed to consist of three figures. Line relay H, which is energized during idle conditions of the line, becomes de-energized by start impulse associatedwith the signalcombinaticn pertaining to the first letter of the stool; designa ion.

Ground is thus connected to distributor start magnet 31 through line relay contact tongue I8, contact 2|, and distributor rings 23 and 21. Brush arm 32 and timing cam I26 are thus released, rotation being imparted from shaft I21 through a friction clutch. The first selecting pulse is also of spacing nature because the signal combination represents one of the letters designating the stock. Ground is, therefore, applied through contact tongue I0, contact 2|, distributorv ring 23 and segment 3I to relay 41, which becomes energized and attracts its contact tongue, thereby opening the locking circuit of relay 4|. Since relay M is already assumed to be de-energized, the operation of relay 41 will be idle.

When brush arm 32 and timing cam !26 have rotated through less than degrees, stop disc I29, secured to cam sleeve I28, is released by lever I38, for rotation. Following the operation of relay 41, which determines that relay 4I shall be de-energized, cam I3I closes contacts II6, thereby applying ground through conductor II4, through the outermost contact and contact tongue of relay 4| to contact tongue I08 of the first figure storage relays 62, but as this relay isv assumed to be de-energized, contact tongue I08 is out of engagement with its contact and the operation of contact II6 by cam I3I is therefore idle. Had contact tongue I98 been engaging its contact, the relay II I would have been energized to apply ground to conductor H9 and to disengage contact tongue II8 from its grounded contact.

After cam I3I has operated its contacts II6, cam I32 opens contacts I22, thereby removing one of the ground connections from conductor I22. This operation also has no effect since the ground at contact tongue II8 of relay III was not removed when contacts II6 were closed. By the time contacts I22 have been operated, letters selecting signal impulses are being applied to the distributor segments 29 and in response to marking impulses, the relays 44 become energized and holding circuits are completed through their holding windings, their holding contact tongues, and through the contacts 5|.

During the reception of the selecting impulses, cam I33 closes contacts I02, thereby connecting ground to the middle contact tongue of relay M and the tongue then being in engagement with its right-hand contact, ground is connected to conductor I06 and to contact tongue I04 of relay 62, the effect of which would be, if relay 62 were energized, to energize relay 86 and remove ground from conductor 84. Since relay 62 is not energized at this time, it is apparent that the operation of contacts I02, under these circumstances, is idle.

Immediately after contacts I02 are reopened, cam I34 closes contacts 89 to connect ground to conductor 90 and to conductor 81 through the outer contact tongue and contact of relay 88, which is then de-energized due to the fact that relay 58 is de-energized, and its contact tongue 98 is disengaged from the contact connected to conductor 99. The ground connection supplied by contacts 89 is thus extended through conductor 81 and the contact tongue and contact of relay 83, and through the winding of relay 58 to battery 82, thereby energizing relay 58 which effect'due to the fact that conductor 99 leads'to the left-hand contactof the center contact tongue of relay 4|, which is not engaged by its contact tongue. Relay 83 is placed in series with relay 58 by the locking contact tongue of relay 58, and both relays remain energized, the relay 83 attracting its contact tongue to its left-hand contact, whereby conductor 81 is disconnected from the Winding of relay 58 and is connected to the winding of relay 59 through the back contact and contact tongue of rela 9|. By the energization of relay 58, a conductive path is completed from the code contact tongues of each of the relays 44 to the conductors in cables 61 and thus to the windings of relays MI in the secondary storage device for letters I42.

When the last of the segments 29 has been traversed by brushes 33, cam I36 closes contacts 56 to connect ground to the code contacts of relays 44 and the ground will thus be connected to those of the code contact tongues which have been attracted, thereby supplying the ground connection through cable 53 and through the contact tongues I8, 14, I3, II, 68 and 68 to the conductors in cables 81 and, therefore, to the corresponding relays I4! which become energized from battery I4'I according to the code combination, and which become looked through the ground provided by conductor IZI and contact tongue N8 of relay III. Thus, the code combination corresponding to the first letter of the stock identification is stored in relays MI and thereafter cam I31 opens contacts 5| thus removing ground from the holding circuits for the relays 44 which become (lo-energized. A first cycle of operation of the brush arm 32 and of the cams controlled by stop disc I29 is completed.

The code combination for the second letter in the identification of the stock, if there is more than one letter, is received in the same manner as the first and controls the apparatus in the same way except that when contacts 89 are closed by cam I34, ground is applied to the winding of counting relay 59, the energizing circuit for ,i which was prepared by pilot rela 83 when it became energized, the relay 83 having remained energized along with relay 58. Upon the energization of relay 59, its holding contact places relay 9! in series with relay 59 and holds both of the relays energized. The energization of relay 59 results in the disconnection of contact tongues 88 from the contact tongues 88 of relay 58 and contact tongues 58 become engaged with the contacts connected to the conductors in cables 89 which extend to the windings of the second set of letters storage relays I43. The energization of pilot relay 3| prepares an energizing circuit for the counting relay 6| so that the latter relay will become energized if there is a third letter in the stock designation. Following the storage of the signal combination in the relays 44, cam I38 closes contacts 55 to transfer the signal combination through cables 53 and 89 to the relays I43 certain of which become energized according to the signal combination and remain energized due to the establishment of holding circuits and relays 44 are released by the opening of contacts 5| by cam I31.

If the stock identification should contain a third letter, the apparatus would operate as previously described to bring about the energization of relays 8! and 92, and the storage of corresponding signal combination in the storage relays I44, Fig. 2. It will be assumed, however,

that there is no third identifying letter and that following the storageof the signa1 combinations in relays MI and I43, the first figure of the price is transmitted by transmitter [2. The first impulse which follows the start impulse will be of marking nature to indicate that the signal pertains to a figure and when that impulse is receiv'ed, line relay tongue I8 will connect ground to distributor ring 22 and through brushes 33 to segment 28, whereby relay 4| will become energized and a holding circuit therefor Wil1 be completedthrough itsholding contact tongue and through conductor48 and the contact tongue of relay 4! to ground.

The middle contact tongue of relay 4| will become disconnected from conductor I86 and Will become connected to conductor 99 while the outermost contact tongue will merely become disconnected from conductor II4, but will not be engaged with any other conductor. The operation of contact II5 by cam I3I will be idle as before because the circuit of relay III, which contacts 5 arearranged to complete, will now be open at the outermost contact tongue of relay 4| as well as at the previously mentioned contact tongue I 88 of relay 82. The operation of contacts I22 will be idle because elay I II is not energized and the ground at H8 is connectedto conductor I 2|. The closure of contacts I82 by cam, I33 following the reopening of contact I22 will result in the connection of ground through contacts I82 through conductor I8I, middle contact tongue of relay 4|, conductor 99, contact tongue 98 of relay 58, which at this time is maintained energizedby its holding circuit, and winding of relay 88 which thereupon becomes energized ,to attract two contact tongues.

I The innermost or left-hand contact tongue,

completesa holding circuit for relay 88 from the ground provided at the contact tongue of relay 85 through conductor 84 and conductor I83. The outer orright-hand contact tongue of relay 88 becomes disconnected from conductor 81 which extends to the break contact of pilot relay, 83, and engages a fixed contact which is connected to the contact tongue of. pilot relay 93, thereby preparing an energizing circuit for the counting relay 82. Following the reopening of contacts I82, contacts '89 are closed. by cam I34 to complete the energizing circuit for relay 62 prepared by relay 83. Relay 62 thus becomes energized and attracts its five code contact tongues 13, the

contact tongues I84 and I88 and its holding circuit contact tongue, which places relay 93 in series with relay 82. Relay 83 attracts its contact tongue which prepares an energizing circuit for relay 63 from conductor 98. The attraction of contact tongues 13 results in their disconnection from contact tongues II of relay BI and their connection instead with the five conductors contained in cable I! which extends to the five relays I12 which comprise-:the first set of storage relays in the secondary storage device for figures I'II.

No operation results immediately from the engagement of contact tongue I88 with its fixed contact, as the circuit of the, conductor I I3 to which contact tongue I88 is connected is interrupted at the right-hand contact tongue of relay 4|. Also, no immediate results occur from the attraction of contact tongue I84, as the circuit which it prepares and which includes conductor I88 is-at this time open at the middle contact tongue of relay 4|. The closure of contacts 58 by cam I38 following the reopening of contacts 89 results in the connection of ground to those of the conductors of cable 53 for which corresponding ones of the relays 44 have been energized.

Since the circuits of the conductors contained in cable 53 now extend through contact tongues I6, I4, I3, and conductors in cable 11 to the relays I12, corresponding ones of the last mentioned relays will become energized and held in that condition by their locking circuits.

If the stock price includes a second figure, the signal combination will be received by the line relay I1 and will be distributed to the relays 4| and relays 44 by distributor 24. During the reception of the signal combination relays 63 and 94 will become energized and locked in that condition to connect the contact tongues I4 to the conductors in cable I8 and to prepare an energizing circuit for the last of the figures counting switching relays 64. If the stock price includes a third figure which may, for example, be a fraction, the relays 64 and 88 will become energized, and the signal combination will be switched to the conductors of cable I9 and thence to the last set of figure storage relays I14 which will become energized and locked according to the signal combination.

At the conclusion of the transmission of the signals pertaining to the designation and price of a stock, the distributor brush arm 32 will come to its rest position and remain at rest unless and until transmitter I2 sends another signal combination, such as for example the signal representing the first letter of the designation of the next stock quotation. In the rest interval preceding the next stock quotation signal brush arm 32 and the cams controlled-by stop disc I29 will be at rest. Relay 4| will be held in energized condition due to the fact that a marking condition. of line relay I I obtained when brushes 34 last traversed segment 3| so that relay 41 did not become energized to interrupt the locking circuit of relay 4|. Relays 44 are de-energized due to having been released when cam I3I operated contacts 5| just before coming to rest. relays. I I l and 86 are de-energized, as many of the letter counting relays 58. 59, and 6| and as many of the figure counting relays 82, 63, and 64 as there were letters and figures in the stock quotation just received are locked in energized condit on, and the relays I4I, I43, and I44 are energized and held in combinations corresponding to the letter signals identifying the stock, the relays I12, I13, and H4 being also energized and held according to the figure codes. The storage 'of the signal comb nations is necessary for the reason that, until a signal having a letter shift impulse must be received by distributor 24, to determine that the previous figure signal was the last of a quotation. When transmission of quotations is to be interrupted for an interval, a dummy quotation consisting of at least one signal including a letter shift impulse and one signal including a figure shift impulse may be transmitted in order to clear out the last quotation by effecting the operation of the perforator. The signal having the letter shift impulse will accomplish this, but will operate the first of the letter signal counting relays. It should be such a signal as will not cause one of the relays I 48 to be operated. The signal combination containing the figure shift impulse is required to clear the letter signal counting relays. It may be any signal including a figure shift impulse, because no relay I48 has been operated, and the perforator will therefore not be operated. The stored figure shift signal will be deleted when the first letter signal of the next stock quotation is received.'

Upon the release of distributor brush arm 32 in response to the start impulse of the first letter signal of the next quotation or of some other signal such as an idle signal in which the letter or figure selecting impulse is of spacing nature, segments 3| and 28 will be traversed by brushes 34 and 33 respectively, ground being applied to segment 8| to complete the energizing circuit for relay 4'! whereby ground is removed, from the locking circuit 46 of relay 4| and the relay is released. The impulse being of spacing nature ground does not become connected to segment 28 and therefore the energizing circuit 39 of relay 4| is not completed and relay 4| remains de-energized after the brushes leave segments 3| and 28.

Shortly after th release of cam controlling disc I29, cam I M closes contact II6 as previously described to connect ground to conductor II4. A circuit may be traced from conductor I.I4 through the outermost or extreme right-hand contact tongue of relay 4| which is now in engagement with its fixed contact, through conductor H3, contact tongue I88 of relay 62 which is non/energized and therefore holds contact tongue I538, which is still held attracted, through conductor I I2, winding of magnet III, conductor I89, and conductor 8| to battery 82. Relay II I will thus become energized and as it has no holding circuit it will remain energized only for the duration of the time that cam I3I holds conta-ct H6 closed, Relay III attracts its contact tongues ill and, H8, the former connecting ground to conductor I I9 and the latter removing one of two grounds from conductor I2I. Ground is thus connected through conductor I I9 to one end of all the cod chains of contact tongues and contacts which control the relays I48, and if the signals corresponding to the stock identifying letters have been such as to establish a complete conductive path to one of the relays I48, or stating it somewhat difierently, if the signals stored in relays I4I, I43 and I44 pertain to a stock in which the subscriber is interested and which is to be printed upon his stock quotation printer, the corresponding relay I48 will be energized. Also the operating winding of relay i556 will be energized and its armature will complete a holding circuit for the particular magnet M8 which has been energized and that relay in turn will complete the holding circuit for the relay I56. At the same time that the holding circuit for relay [56 is completed, ground is connected directly to those of the punch interponent controlling magnets that are permanently coded, ground is connected to punch interponent controlling magnets I96 through cable I68 according to the code established by the relay I48 that is energized, ground is connected to the punch interponent controlling magnets I88, I88 and 21H through cables I86, I81, and I88 respectively according to the energization of magnets I12, I13, and H4, respectively and ground is connected to the winding of perforator start magnet 203. Thus the perforator mechanism I 9| is set in operation.

Before contacts IIS controlled by cam I3I reopen and release relay III, contacts I22 are opened by cam I32 to remove the second ground from conductor I2I. The holding circuits for storage relays I4I, I43, and I44 are thus interrupted and those of the relays which had been energized are released. After contacts I22 have reclosed, contacts I02 are closed by cam I33, ground is connected to conductor IIlI and through the middle contact tongu of relay M which is in its right-hand or released position to conductor m8 and thence through contact tongue Iitl of relay E2 and conductor It! to relay $6 which attracts its contact tongue, removing ground from conductor 84. Conductor 84 is included in the holding circuits of counting re-' lays 58, 59, Si, 62, 83, 64, 83, 9|, 92, 93, 94, 96, and relay 88, so that these relays are all released and are restored to the condition originally described, which is the condition for the storing of the next stock quotation, From this point on the contacts controlled by cams [3d, I36, and i3? operate in the manner previously described to energize relay 5%, to transfer the signal combination which has just been received and stored in relays M through contact tongues 66 and cable iii to relays MI, and to release relays M in preparation for reception of the next signal combination.

From the foregoing it will be apparent that the secondary storage device for letters I42 and all of the apparatus ahead of that device is released immediately after the perforating mechanism is set in operation. Those of the relays H2, H3, and lid which have been energized re in that. condition for the reason that the punch interponent controlling magnets are not provided with locking circuits and the relays of the secondary storage device for figures HI must remain energized until the signal combinations have been perforated in the tape ZII. While the perforating operation is being carried on, the signal combination pertaining to the letters identifying the next stock quotations may be stored in the secondary storage device for letters M2.

The perforating operation is completed when shaft 298 has completed one-half revolution and is arrested by magnet controlled lever 2% cooperating with stock disc 2531. Just before shaft 258 is arrested one of the two diametrically opposed apices of cam 29% actuates cam controlled g' contacts 559 to remove ground from conductor Conductor N53 is part of the holding circuit extending through tongue I57 of magnet and through conductor H515 to the holding contact tongues E52 of the magnets M8, so that the holding circuit of any one of the magnets that has been energised is interrupted and the magnet is released when the ground is removed at contacts Mil. Conductor M8 is also included in the locking circuit of figure storage relays I12, H3, and H4 through conductors I'EEi, HT, and 5118, so that any of those relays which had been energized are released upon the removal of ground from conductor I58 and are permitted to return to normal condition thereby being pre-- pared to be reset in accordance with a new price quotation, ground thereby being removed from all of the punch interponent controlling magnets contained in perforator IQI so that all of those become de-energized. Those of the perforator magnets that are permanently coded receive ground connection through the outermost contact tongue of any storage relay M8 which had been energized, as

does also the locking circuit for relay I 5%. Upon the release of the previously energized storage relay hid the locking circuit for relay IE6 is interrupted as are also the circuits of all of the permanently coded perforator magnets, these being the magnets I94, I91, and 262. Just before cam 209 is arrested its apex which had opened contacts I59 moves out of engagement with the cam follower and permits contacts I59 to reclose, thus reconditioning the locking circuits for the storage relays I48, H2, I13, and

' I'l for the control relay I56 and for all of the punch interponent controlling magnets in the perforator l9l.

By means of the apparatus described up to this point a perforated tape may be prepared containing signal combinations representing the price quotations of selected stocks, each quotation being accompanied by a single identifying code combination, although the quotation as received from the transmitter may have included one, two, or three identifying letters, and the quotation is further accompanied by a letters shift signal combination, a figures shift combination, and a combinedline feed and carriage return combination.

Referring now to Fig. 3, the reference numeral 255 indicates generally a tape transmitter and the reference numeral 2!? designates the tabulating control apparatus for a page printer, which may be the type shown in Patent 1,904,164 granted April 18, 1933 to S. Morton et al. The printer shown in this patent when modified by ne addition of the tabulating control mechanism to be described hereinafter, is somewhat related to Patent 1,629,236 granted March 8, 1927, to L. M. Potts. The tape transmitter ZIB may be generally similar to the transmitter shown in Patent 2,057,111 granted October 13, 1936, to L. M. Potts; also it will be apparent that the transmitter shown in the patent includes numerous features that are not required in a transmitter adapted to the present invention.

Tape 2H passes between guide plates 2I8 and 2| 9 in a tape reader mechanism MI and the code combinations are there sensed by sensing levers (not shown) which control movable contacts 222 of which there are five in the present embodiment of the invention. Contacts 222 are engageable with a fixed contact 223 to which grounded battery 22 is connected. The tape reader has a sixth movable contact 225 to be controlled by a sensing pin (not shown) which senses the marginal perforation that appears in the tape accompanying the carriage return and line feed signal at the end of each quotation. The five code signal contacts 222 are connected individually to conductors in a cable 221 and at the opposite end of the cable the five conductors are connected to the five code segments of the segmented ring 223 of a transmitting distributor 229. The sixth movable contact 226 is connected to one end of the winding of a relay 23I the other end of which is grounded.

In addition to its segmented ring 228 transmitting distributor 2255 is provided with a cc-n tinuous conductive ring 232 which is connected by conductor 233 to selector magnet 234 of the tabulating printer. If the printer is located at the same station Where tape transmitter 21% including transmitting distributor 223 is located, conductor 233 will be a local conductor but if the printer is located at a remote point conductor 233 may be a telegraph line. Segmented ring 223 is engaged by brush 235 and continuous ring 232 is engaged by brush 237, the brushes 235 and 23'! being connected together electrically and being supported by motor driven brush arm 238 which is normally held arrested by latch 239. Besides the five code segments, segmented ring228 includes also rest segment 2M which is connected to battery 224 by conductors 242 and 243 and start segment 244 which has no conductor connected to it.

The single contact tongue of relay 23! is connected to battery 224 through conductors 246 and 243 and the single fixed contact with which it becomes engaged when relay 23! is de-energized is connected by conductor 24'! to the outermost contact tongue of a relay 24-8. One end of the winding of relay 248 is connected to ground and the other end is connected to the fixed contact with which the outer contact tongue of relay 248 is engageable when the relay is energized and is also connected to one contact of a pair of contacts 249 controlled by a tape slack arm 25! in such a way that when the amount of tape b tween perforator It! and tape reader 22! is below a predetermined value contacts 24$ are open and when the amount of tape between the perforatcr and the tape reader is above a predetermined length the left-hand end of tape slack arm 25! will be lowered and contacts 222 will become closed. The other of the two contacts 249 is connected to battery 224 by conductor 243. From the foregoing it will be apparent that relay 248 will be energized at any time that contacts 245 are closed and may be held in energized condition after contacts zce are opened by a holding circuit through its outermost tongue and through conductor 24?, the contact and tongue of relay 23! conductors 246 and 243 to battery 224. When relay 248 has once been energized it will not be released until relay 23! has been energized to attract its contact tongue, and this operation occurs only when the sixth movable contact 226 of the tape reader engages conductive bar 223 due to the fact that the sixth sensing lever senses a marginal perforation accompanying a carriage return and line feed signal at the end of a stock quotation.

The innermost contact tongue of relay 243 is connected to conductor 252 which extends to the tabulating control mechanism of the printer as will presently appear. The fixed contact which the inner contact tongue of relay 248 engages is connected to ground. It may be stated however with reference to conductor 252 that it extends to one of a pair of normally closed contacts in the tabulating control circuit of the printer and from the other of the two contacts extends the conductor 253 to connect to one end of the winding of a start magnet 254 for releasing distributor brush arm 238 for operation, by the attraction of stop latch 239. The other end of the winding of start magnet 254 is connected to battery 256.

The tape reader and signal transmitting mechanism is shown in Fig. 3 in the rest condition with a loop of tape 2i between perforator l9! and tape reader 22! insufiicient to effect closure of contacts 249 and with fixed contact 226 disengaged from contact bar 223 so that relay 23! is de-energized and its contact tongue is in engagement with its fixed contact. Moreover, relay 248 is de-energized because contacts 245 are open, and since the innermost contact tongue of relay 248 is included in the circuit of start magnet 254 for the transmitting distributor 229, magnet 254 is de-energized and brush arm 2% .is held in rest condition by start latch 239 with its brush 235 engaging rest segment 24! which is always connected to battery 224 and thus holds the selector magnet 234 of the printer energized, so that the printer is at rest.

Upon the perforation of a set of signal combinations representing a stock quotation, tape 2! l is advanced out of the perforator thereby increasing the slack between pcrforator l8! and tape reader 22! and permitting tape slack arm 25! to rock in counterclockwise direction and close contacts 249 whereby battery is connected to relay 248 and the relay attracts its contact tongues. It

is frequently the custom to arrange the timing in tape transmitters so that the sensing pins shall be Withdrawn and the tape advanced to bring the next signal combination into alignment with the sensing pins just before the distributor brush arm comes to rest. It will be assumed that this is the mode of operation in this instance, so that the first code combination of a stock quotation group is in position to be sensed by the sensing pins, but the pins are held retracted and therefore the contacts 222 and 226 are disengaged from contact bar 223 and relay 23! is tie-energized so that the holding circuit for magnet 248 requires completion only at its outermost contact tongue, and upon energization of the relay 248 the tongue is attracted and the holding circuit is completed. At the same time that the holding circuit for relay 248 is completed by its outermost contact tongue the energizing circuit for start magnet 254 is completed by the attraction of the innermost contact tongue, and brush arm 238 is released for rotation. Upon being so released, brush 25% moves off the rest segment 24! and onto start segment 244, thereby interrupting the circuit for printer magnet 234 which starts the printer in operation. At the same time the sensing pins are permitted to sense the code combination and code segments 228 are connected to battery 224 through cable 221 and through certain of the movable contacts 222 of tape reader 22! according to the code combination sensed. The code combinations contained in the tape are thus transmitted one after another to selector magnet 234 of the tabulating printer until the slack is taken up in tape 2!! and contacts 248 have opened. The transmitter will not be arrested immediately upon the opening of contacts 249 because the holding circuit continues to be complete until contacts 226 are closed, due to the sensing of a marginal perforation which designates the code combination as the last in a quotation group. Upon the sensing of the marginal perforation, relay 23! becomes energized to incorrupt the locking circuit of relay 243 which becomes de-energized and interrupts the circuit of start magnets 254 so that stop latch 239 is released and brush arm 238 is arrested as it completes a cycle of rotation. Because of the fact that it is desirable to complete the sensing and transmission of signals epresenting a stock quotation group before the tape transmitter is arrested, the tape slack arm 25! is arranged to open contacts 249 before tape 2!! has actually been drawn taut by tape reader 22!, thus providing slack tape to be taken up as the tape is advanced to complete the sensing of the stock quotation group.

The identity of the tabulating tape printer with the printer disclosed in Patent 1,904,164 of S. Morton et a1. will be readily apparent by comparing Fig. 4 herein with the disclosure of that patent. The printer has a pivotally mounted platen carriage v26! the pivotal position of which determines the printing of figures or letters but which is not movable laterally of the printer. A type basket carriage 262 which is supported by rollers 2B3 resting upon rails 264 is movable transversely of the printe for letter spacing and carriage return. Type basket carriage 282 supports type bars 266, pull-bars 26?, code bars 268, and ink ribbon apparatus 269. Code bars 268 are controlled by selector vanes 2H which in turn are controlled by a single magnet selector mechanism (not shown). Functions are controlled by function levers 212 which in turn are controlled by operating bail 213 which also operates print bail 2W. Bail 213 is operated from main shaft 216 which also imparts character spacing movement to type bar carriage 282, through gear 211, shaft 2'l8, pinion 219 and rack 28! under the control of spacing pawl 34!.

As shown in Fig. 5, and also in the lower portion of Fig. 3, each of the selector vanes 21! has associated with it a pair of electrical contacts 282. Contacts 282 are arranged to be open when the selector vanes are positioned to correspond to a spacing condition and are closed when the vanes are moved into the position corresponding to a marking condition. Referring now to Fig. 3, it will be observed that the movable ones of the contacts 282 are connected to a conductor 283 which extends to a fixed contact normally engaged by the outermost contact tongue of a relay 28 5 and that from the contact tongue a conductor 288 extends to grounded battery 28?. The fixed one of each of the contacts 282 is connected to one end of the winding of a relay 288 of which there are accordingly five. The other end of the winding of each of the relays 288 is connected by conductor 289 to ground. From this, it will be observed that Whenever any of the contact pairs 282 is closed by its associated selector vane 21!, its associated relay 288 will become energized over a circuit beginning at grounded battery 28'! and extending through conducto 286, through outer contact tongue and fixed contact associated with relay 288, through conductor 283, contacts 282, and winding of associated relay 288 to ground through conductor 289.

Each of the relays 288 is provided with a plurality of contact tongues equal to the number of code storage relays i 58 plus two additional contact tongues. The contact tongues of each of the upper four relays 288 are connected to the corresponding fixed contacts of the relay next below it and the contact tongues of the lowermost relay 288 ar connected to the outer-fixed contact of a relay 29E, the outer contact tongue of which is connected to ground. The innermost fixed contact of the uppermost of the relays 288 is connected to one end of the operating winding of a relay 292, the next fixed contact is connected to one end of the operating winding of the previously identified relay 284 and those of the remaining fixed contacts of uppermost relay 288 that have been shown in the drawings are connected to one end of the operating windings of relays 293 and 298. It is to be understood that relays 288 have many more fixed contacts and contact tongues than have been shown in the drawings and that the additional fixed contacts associated with the uppermost of the relays 288 are connected to the operating windings of other relays similar to the relays 293 and 298.

Certain of the fixed contacts or relays 288 are arranged to be engaged by their associated contacttongues when the relays are de-energized and others are arranged to be engaged by their contact tongues when the tongues are attracted, the

arrangements being similar to the arrangement of the .fixed'conta'cts of relays M1, I= l3' an'd M'4fso that as the relays 288 are energized in various permutational combinations, difierent conductive paths are established from the outer fixed contact of relay 29l to the relays 284, 292, 293 and 5 294 and the other relays corresponding to relays 293 and 294. Only one such conductive path may be completed in response to any permutational energization of relays 288 under the control of selector vanes 2. The innermost row of contact tongues and contacts is arranged to establish a conductive path to relay 292 in response to the signal combination perforated under the control of perforator magnets I94, which is the unshift signal. The next row of contact tongues and contacts is arranged to establish a conductive path when relays 288 are energized according to the signal combination perforated under the control of magnets I91, which is the shift signal. The remaining alignments of contact tongues and contacts shown are arranged to respond to codes perforated in the tape under the control of magnets I98 and the coding corresponds to those established by two of the relays I48. Other alignments oi contacts and tongues will be coded to correspond to the codes established by others of the relays I48.

Relay 29!, which connects ground to the tongues of the lowermost relay 288 by attracting its grounded outer contact tongue into engagement with its fixed contact, has one end of its winding connected to ground and the other end of the winding connected to one of a pair of normally open contacts 296 carried by the frame of the printer as shown in Fig. 5, and arranged to be closed momentarily by the lever 29'! which trips the clutch for driving the main operating cam assembly, the lever 29! being operated by sixth cam projection 298 of the selector cam assembly.

The other of the two contacts 296, which in Fig. 3 is the movable contact, is connected to conductor 283 which is normally connected to battery 28! through a previously identified circuit. lhus, upon the closure of contacts 296, relay 291 becomes energized and attracts its two contact tongues, the inner of which engages a fixed contact that is connected to the battery end of the winding of relay 29i to establish a holding circuit, the inner contact tongue being connected by conductor 299 to the fixed contact of a relay 3M, the contact tongue of which engages its fixed contact when relay 38! is ole-energized. The contact tongue is connected to conductor 283 for supplying a holding connection for the winding of relay 29! from battery 28?.

One end of the winding of relay SM is connected to battery 382 and the other end is connected by conductor 383 to the opposite ends of the operating windings of the relays 284 and 292 from those to which the first two fixed contacts of the uppermost relay 288 are connected, so that when contacts 296 close and relay 29! becomes energized, the energizing circuit for relay 284 or 292 extends from ground to the outermost contact tongue of relay 2'9I, through a chain of contacts and tongues of relays 288, through the winding of relay 284 or 292, through conductor 383 and the winding of relay 38l to battery 382 which is grounded. The operating windings of relays 293 and 294 and all other similar relays are also connected to conductor 383 so that relay 38| is energized when the relay 293 or 284 is energized, but the connection is through conductor. 385, through the outer contact and tongue of relay 292, and through conductor 304 to conductor 383. 75 Theou'te'r contact and-contact tongue of relay 292 are normally disengaged so that relays 293 and 294 can be energized only when relay 292 isv energized.

Relay 292, which responds to the unshift code combination, has a holding winding, one end of which is connected by conductor 309 to ground and the other end of which is connected to the inner fixed contact of the relay. The innermost contact tongue of relay 292 is connected by conductor 301 and conductor 308 to a rest segment 399 and to a first group of interconnected segments 3! I of a tabulating control commutator 3i 2. commutator 3I2 includes a row of segments supported by an insulating bar 3H4 (Fig. 4) extending across the printer and supported by the frame thereof, and a continuous conductive bar also supported by insulating bar 3| 4, the continuous bar being identified 3|6. A brush carrier 351, secured to the movable type bar carriage 202, supports electrically interconnected brushes 3|8, one of which is in engagement with the row of conductive segments, and the other of which is in engagement with the continuous conductive bar 3l6. The row of conductive segments includes a segment for each character printing position and nonconductive mounting bar 3l4 is so positioned that when type bar carriage 262 is at its beginning-of-line position, one of the brushes 3l8 engages the rest segment 309 and when carriage 262 is in its extreme end-ofline position, the brush engages the last segment in the row. The continuous conductive bar 3I6 is connected to grounded battery 281 so that when brushes 3 l9 engage segment 309 or any one of the segments 3H, they extend the holding circuit from conductor 308 through conductive bar 3E3 to battery 281.

All of the segments in the commutator are interconnected in groups, such as the groups of segments 32!, 322, and 323. The interconnected segments 32! are connected by conductor 324 to the outermost contact tongue of relay 293, the interconnected segments 322 may be connected to a similar relay (not shown) and the interconnected segments 323, which have been indicated as the last group of segments, are connected by a conductor 320 to the outermost contact tongue of relay 294. The outermost fixed contacts of relays 293 and 294 and of any similar relays are connected by conductor 321 to conductor 308 so that when relays 293 and 294 and all similar relays are de-energized and their outermost contact tongues engage their associated fixed contacts, all of the segments of the commutator are connected to battery 28! through continuous bar 3 l 6, brushes 3 l 8, interconnected rest segment 309 and segments M l, conductor 308, conductor 321, outer contacts and tongues of relays 293 and 294, and conductors 324 and 326. Upon the energization of either of the relays 293 and 294, the group of segments connected to the outer contact tongue associated therewith will be isolated from battery 281.

One end of the holding winding of each of the relays 284, 293 and 294 is connected by conductor 32:": to grounded battery 302 and the other end of each holding Winding is connected to the innermost fixed contact of the relay. The innermost contact tongue of each of the relays is connected by conductor 328 to the fixed contact of relay 329, the grounded contact tongue of which normally engages its fixed contact. One end of the winding of relay 329 is connected by conductor 33! to the middle fixed contact of relay 284, the

contact tongue of which is connected to grounded conductor 306 and the other end of the winding of relay 329 is connected to the outermost contact tongue of relay 332. The outermost fixed contact of relay 332 is engaged by the outer contact tongue when the relay is de-energized and is connected by conductor 333 to conductor 308, which is normally connected to battery through rest segment 309 and brushes 3l8. The center fixed contacts of relays 292, 293 and 294 are connected together by conductor 334. The center contact tongue of relay 292 is connected to grounded conductor 306 and the center contact tongues of relays 293 and 294 are connected by conductor 339 to one end of the operating Winding of relay 332, the other end of which is connected to the outermost contact tongue of relay 332, to receive battery connection from conductor 333, as does relay 329. cuit for relay 332 extends through the center contact and tongue of relay 292 and through the center contacts and tongues of relays 293 and 294, it will be apparent that relay 292 must be maintained energized by its holding circuit at the time relay 293 or 294 is energized in order for relay 332 to be energized. Relay 332 has its innermost contact tongue connected to battery conductor 333 and the innermost fixed contact of the relay is connected to one end of its holding winding, the other end of which is grounded, and the innermost fixed contact is also connected to one end of the winding of electromagnet 331, the other end of which is grounded.

Electromagnet 331 is also shown in Figs. 4 and 6 and its pivoted armature 33B engages a pin 339 carried by spacing pawl 34!. Spacing pawl 34! normally engages spacing ratchet 342 and holds it stationary. Ratchet 342 is driven from shaft 216 by a friction clutch (not shown) with which is associated a gear (not shown) which meshes with and imparts rotation to spacing shaft gear 211. For normal single-character spacing in the printer, a bail operated lever arm 343 rocks spacing pawl 34l clockwise to withdraw it from blocking engagement with ratchet 342 and, at

; the same time, a check pawl 344, which has an arm 349 engaging bail operated lever arm 343 on the opposite side from the point of engagement with spacing pawl 34!, is rocked clockwise by tension spring 341 wihch interconnects spacing pawl 3M and check pawl 344 to limit the rotation of ratchet 342 to an amount which will give one character space. When magnet 331 is energized, pawl MI is withdrawn from the path of the teeth on ratchet 342, but the check pawl 344 is not permitted to rotate clockwise because it is held by bail operated arm 343 which at the time is stationary. Thus, spacing ratchet 342 is permitted to rotate continuously as long as magnet 331 remains energized and holds pawl 34I disengaged from ratchet 342.

Referring now to Fig. 4, it will be observed that the printer has a sixth vane 341 similar to the five selector vanes 21L Vane 341 is controlled according to the shift and unshift signals, being presented in extreme counterclockwise position, as shown in Fig. 4, in response tounshift or letter case signals and being rocked to extreme clockwise position in response to shift or figure case signals. When vane 341 is presented in the position shown in Fig. 4, it permits clockwise movement of function lever 212 and through it restricts clockwise movement of bail 213 and the movement of print hammer pull bar operating bail 214 and of normal spacing arm 343 so that neither printing nor single character spacing will Since the energizing cirbe performed in response to signal combinations following the unshift signal. When vane 34! has been positioned in response to the figure shift signal, function lever 212 will be blocked and the movement of bail 213 will not be restricted so that the type bars 266 may be operated as selected to effect printing and spacing bail arm 343 may operate to effect single character spacing.

The operation of the printer, as modified by the control circuit shown in the lower portion of Fig. 3, will now be described. As transmitting distributor 229 begins to operate, it impresses signaling impulses upon conductor 233 and thus upon selector magnet 234 of the printer according to the first code combination in a stock quotation group which is the unshift or letters combination. Through the selector mechanism in the printer, selector vanes 21! are set under the control of selector magnet 234, the setting of the vanes 2' being in clockwise direction for all five, whereby all of the contacts 282 are closed and the magnets 288 are energized. Thus, all of the contact tongues associated with the relays 283 are attracted and for this particular signal combination, in which all of the selecting impulses are of marking nature, the conductive path is prepared for relay 282 through the innermost contact tongues and contacts of all of th relays 2823.

Near the end of the receiving cycle, the selector cam assembly closes contacts 296, thus energizing relay 29! over a circuit extending from grounded battery 28?, conductor 286, outermost contact and tongue of relay 284, which at this time is de-energized, conductor 283, contacts 296 and winding of relay 25I to ground. A holding circuit for relay 29! is established through the contact and tongue of relay Sill, through conductor 299, and through the innermost contact tongue and contact of relay 29!, and in addition the prepared circuit for the energization of relay 2?;2 is completed by the engagement of the grounded outer contact tongue of relay 29! with the outer contact. Relay 292 thus becomes energized by current supplied from battery 322 through the winding of relay 3!!! and conductor 323, so that relay 33! also becomes energized and attracts its contact tongue, thus opening the holding circuit for relay 25H which becomes de-- energized, if and when contact 295 have reopened. As relay 26.42 becomes energized, it attracts its three contact tongues into engagement with their respective contacts. A holding circuit for relay 292 is established by the innermost contact and tongue from battery 28! through continuous conductive bar 3l5, brushes 3H3, rest segment 309, conductors 3&8, 3M and 368 to ground. The center contact and tongue of relay 2552 prepares for the energization of relay 332 by closing the energizing circuit at one of the two points at which it is open, the circuit remaining open at the parallelly connected center contacts and contact tongues of relays 293 and 294 and all similar relays. The outermost contact and tongue of relay 292 prepare an energizing circuit for the relays 29S and 294 by interconnecting the conductors 3M and 325 that are included in the energizing circuits of those relays, but which are disconnected when relay 292 is de-energized.

The next signal combination to be applied to i the selector magnet 23 3 is that which was established by one of the storage relays I48 and, therefore, identifies by a single code combination a stock which may have been identified by one, two orthree letters as originally transmitted. No-

character will be printed in response to this code combination as the sixth vane 34'! was set in response to the unshift combination to prevent effective operation of the printing and spacing bails. Selector vanes 2' will be set according to the stock identifying code combination and corresponding ones of the relays 288 will be energized according to the closure of contacts 282. It will be assumed that the signal combination is such as to establish a conductive path through the third row of contact tongues and contacts, counting from the left, so that an energizing circuit will be prepared for relay 293. Upon the closure of contacts 296, relay 291 will become energized and locked and an energizing circuit will be completed for relay 293 from battery 302, through relay 3M, conductors 363 and 3M, outer contact and tongue of relay 292, and conductor 3% to the operatin windin of relay 293 and thence to ground through the outer contact and tongue of relay 29!. Relay 32! thus becomes energized along with relay 293 and opens the holding circuit for relay 29! which becomes deenergized. The innermost contact and tongue complete a holding circuit for relay 293 which extends directly to battery 392 without going through the winding of rela 39!, but Which includes the contact and tongue of ole-energized relay 322. The middle contact and tongue complete the energizing circuit for relay 332 and the outer contact tongue disconnects segments 32l from conductors 308 and 321 and thus segments 322 are isolated electrically from all of the other segments which are connected together electrically through conductor 328, conductor 32'! and the outer contact and tongue of relay 294 and all similar relays.

Relay 332, upon becoming energized, attracts its three contact tongues. The innermost contact tongue completes the holding circuit for the relay and also the energizing circuit for electromagnet 33?. The outermost contact and tongue of relay 332 opens the energizing circuits for relay 329 which is not at this time energized because of the fact that its circuit is also open at the center contact tongue and contact relay 284, winch is not energized. The center contact and tongue of relay 332 are connected to the previously identified conductors 252 and 253 included in the energizing circuit for start magnet 254 of transmitting distributor 229 and this circuit becomes opened at the center contact and tongue of relay 232 to release magnet 254 and thus arrest transmitting distributor 229 at the end of a cycle and delay the transmission of further signal combinations to afford the type bar carriage 262 (Fig. 4) time in which to space to the position at which the stock price is to be printed as selected by the tabulating control relay 293. The release of magnet 254 may not occur until after brushes 236 have moved ofi of rest segment 22! and have begun to transmit the next signal, which is the figure shift combination. Since this signal selects a function, and not a recording operation, the function may be perparted to type bar carriage 262 through shaft 216, gear 211, shaft 218, pinion 219 and rack 28!.

As the carriage 262 travels towards its end-ofline position, brushes 3 I 8 move off of rest segment 309 and traverse segments 3| I, thereby continuing to supply holding current for relay 332. However, when brushes 3I8 encounter the first of the segments 32!, they apply a battery connection from battery 281 to conductor 324, but since the outermost contact tongue of relay 293 is disengaged from its contact, the battery connection is not applied to conductor 321, 388, 301 or 333 and thus the relay 332, relay 292 and electromagnet 331 become de-energized, the type bar carriage 262 thus being arrested by restoration of spacing pawl 34! to effective engagement with spacing ratchet 342, the energizing circuit for start magnet 254 of transmitting distributor 229 being reclosed and the energizing circuit for relay 329 being reprepared at the outer contact and tongue of relay 332.

The next signal combination to be established in the selector vanes 21I is the figure shift combination. This signal combination results in shifting of the platen carriage 26l to its shift or figure printing position in accordance with the normal operation of the printer, the platen having previously been shifted to its unshift or letters printing position in response to the first signal combination of the group. The shift combination also establishes through the second row of contact tongues and contacts of relays 288, counting from the left, the energizing circuit for relay 284 which becomes energized and along With it relay 38| which interrupts the holding circuit for relay 29L Upon the energization of relay 284, a holding circuit is completed through its innermost contact and tongue. Its center contact and tongue connect ground to the winding of relay 329, but this relay does not become energized at this time because the segments 32 I, which battery supplying brushes 3l8 engage, are not connected to the conductive path comprising conductors 321, 308 and 333, relay 293 being still held energized by its holding circuit, and its outer contact tongue therefore maintaining the energizing circuits of relays 332 and 329 open. The outermost contact and contact tongue of relay 284 disconnect conductor 283 which extends to contacts 296 and to all of the contacts 282 from conductor 286, which is connected to battery 281, thus preventilng magnets 288 from being energized as long as relay 284 remains energized.

The receiving printer has now been conditioned for the printing of figures and through its tabulating control circuit and apparatus shown in the lower part of Fig. 3, it has been conditioned for the printing of those figures in a particular vertical column pertaining to the stock, the price of which is to be printed, as a result of the selection of relay 293. The printing and spacing mechanism of the printer operate normally for the printing of the price, and the code combinations representing the figures of the price do not in any way aifect the tabulating control circuits and apparatus because battery 281 is disconnected from the contacts 282 and 296 and the relays 288 cannot become energized.

After the last figure of the price has been received, the final code combination in the group is transmitted by distributor 229 to the selector magnet 234 of the printer, this being the combined carriage return and line feed signal. This signal has no effect upon the magnet 288 but it selects and sets in operation the line feed and car riage return function mechanism of the printer. thus causing type bar carriage 262 to be restored to its beginning-of-line position. Brushes 318 are thus moved back across segments 3H to come to rest upon segment 309. As soon as brushes 3I8 encounter segments 3| I, battery is again applied directly to conductor 388 and 333 and thus to the operating winding of relay 332 and to relay 329. Relay 332 does not become operated because its energizing circuit is now opened at the center contact tongue of relay 292 which was previously released. However, relay 329 does become energized through the center contact tongue of locked relay 284 and relay 329 attracts its contact tongue to remove ground from the holding circuit of relays 284 and 293 which become tie-energized. Thus, the tabulating control mechanism is restored to normal condition, with all of the relays de-energized and with battery reconnected to one side of each of the pairs of contacts 282 and 296 in preparation for the reception of the next group of stock quotation signals.

Fig. 8 illustrates the kind of tabular recording of stock quotations that may be achieved with the apparatus according to the invention. All quotations pertaining to particular stocks are printed in their own vertical columns. Since the printer returns to its beginning-of-line position and line feeds the paper between any two successively received quotations, no two quotations are printed upon the same line. In any particular column, printed quotations may occur frequently or sparsely, depending upon the relative activity in the several stocks. Regardless of the spacing between any two quotations relating to the same stock, they may be observed merely by looking up or down the column to which they are assigned.

Fig. 8 also illustrates an arrangement by which the various columns and the stocks assigned thereto may be identified, so that the paper upon which the quotations are printed may be plain and unruled. The arrangement involves the use of a sheet 35! of transparent material, such as glass, Celluloid or other plastic material, preferably colorless. The sheet 35! is mounted so that paper 352 upon which quotations are printed passes upwardly behind the sheet 351 as it leaves the platen. The sheet 35I is vertically ruled, scored or otherwise provided with lines, as at 353, which establish visible columns in which the quotations appear, thus making easier the observation of quotations pertaining to any stock. The stock identifying symbols may be applied to sheet 35I near the top, and between the rulings, as shown in Fig. 8, thus completely identifying the columns and the quotations contained therein.

With reference to the tabulating control segments which the type bar carriage brushes engage, it is to be noted that the grouping of the segments in threes is purely for purposes of illustration. Some stock prices may consist of only a single digit and a fraction and such a quotation would require only two character spaces. Accordingly, only two segments would be required to determine the location and the space allotted to it and thus the width of the page would be utilized to the greatest advantage. Other stock prices may involve three digits and a fraction and, accordingly, four segments would be connected together electrically to represent the space allotted to quoted prices for that stock. It should be noted that for the accommodation of such quotations, an additional set of relays would be required in the secondary storage device for figures and correspondingly an' additional set of punch
