oonrone'rron or NE YORK QUOTATION BOARD PRINTING UNIT Appl ication filed May 4,

This invention relates to a quotation board mechanism for automatically printing in visible form information concerning difierent items, such as stock, bond, and commodity quotations in response to telegraphic signals, and more particularly to apparatus which inaddition to displaying information of the usual character, such as quoted market value,

can, when desirable be operated'to indicate 'matically posting stock quotations at a plurality ot' separate places, such as brokers otfices and banks, tr m a common transmitting point, involves the use of four channels of communication extending between the transmitting station and the receiving station embodying the quotation board apparatus, separate channels being employed to transmit signals correspondingto each of the hundreds, tens, units, and fractions (in eighths) value or digits of the quotations. The tour transmitting channels may comprise four separate line wires or two line wires, each having'battery of positive and negative polarity applied alternately thereto in a series of impulses, in conjunction with polarized relays at the receiving station for responding to the polarity of the current transmission from adistant initial orsendingstationmay be accomplished over a single wire to a local decoder or repeater station from which the various channels or lmpulses 1931. Serial No. 535,065.

are separated and sent out to the various quotation boards. Or again the single wire may go directly to the subscribers cabinet'where a decoder separates signal channels and transmits them to the quotation board mechanism in the usual manner.

Quotation boards as heretofore constructed employ a group of four indicating units,

each having a dial or drum bearing the nu merals 1 to 9, O and a blank, four units being disposed side by side behind suitable apertures so that when properly set up the numerals on the dials may be directly observed to give the quotation. Ordinarily, five of such groups of indicators are provided for each stock or item, corresponding to the quotation ranges chosen to be posted, such as yesterdays close, open, high, low, and last quotations of the stock, and signals are transmitted to the quotation board to operate these at appropriate times. On the other hand, the number of range signals transmitted is by no means limited to five. Other signals representing any combination of the above ranges or signals to indicate bid, ask, up, and down or any other desirable range or other information may be transmitted.

In an arrangement described and claimed and apparatus, filed May 9, 1930, Ser. No.

451,1t0, and assigned to WVestern Union Telegraph Company, it has been proposed to use,

in place of one or more of the five range groups of indicators provided for each stock. a printing unit which shall make the information visible in printed form on a paper tape or other sheet material. Ordinarily the group of indicators corresponding to the last quotation will be displaced by the printing unit. This arrangement enables the consecutive quotations to be kept in viewfor an extended length of time as new quotations are being printed on the tape, and thus indicate what is termed the trend of the stock being quoted upon.

It will be observed that in the quotation board system as above described, there is included among the groups of indicators for high and low ranges.

vconsecutive quotatlons occur in printed form,

thevarious stock ranges a group for the However, when as for instance, on a strip or tape of paper,

a person referring to the information displayed'thereon inorder to casce-rtain tlie trend of the stock being quoted upon, would 11nd that the information would be more useful if there were means printedon the tape ior in dicaiting sech-quotationsas represented a new high or a new low a bid or asked or other speclal value. Although each new high, low, bid, or asked or other value could be indicated .in.a systemhaving the required number. of stock range indispecial-value. For accomplishing this asuitable arrangement may be employed for dis- ,phi-yliing a character indicating such information :along with the zchara cters indicating the value of theiquotation. 1 v More particularly, therefore, it is .an obejectof our ainventionto provide :a quotation board unit adapted to be used in a sysitemv'such as described in the-above mentioned applications which will have means to display an indication "along with the quotation -;displayed :by ssuch unit, which will signiiy that the quotation is of an unueuaioharacter, filor e'aanaple, that itrepresents anew high :a new low, a bid, or asked or other quotationof specialsignificanceior value.

This :may be accomplished in aprinting nnitby providingan arrangement ,for mounting an H, L, a B or-a-n A or other character so that they may he moved into printing position and by providingv electromagnetic actuating means responsive to .the

. h low or other special range selectingsignail to selectively bring any desired character tlnto (print-in g -position. I ,Thererore another Ob]6.Ct of our invention is to FP'IlQViCiG inn printing unit means to print an H, L, B,Aor other spccialchan lacter with or :as :a part eof the quotation, and which an ay be selectively brought into action to print a predetermined one of .thespecia-l characters to designate (the rai-ige -01" any zetherspeciad characteristic of the quotation,

displayed.

.Still another object is to provide a mechanism responsive to certain selective signal impulses for causing a predetermlned special characterto be printed.

A stillfurther object is to provide a special control arrangement -vvhich willact in response to certain rangezsignal impulses to effect printing from the special characters simultaneously with the printing of the nu1ner- 'ical characters. 7 i These and other objects areefl'ected icy our invention,=a:s will be apparent 'iirom 'the following description and claims taken in connection with the accompanying drawings .which .form apart of this application, in which: I

:the quotation board systern 'describedin our :aitorelnentioned :copending application entitled, Electrical selecting and indicating system, :a :train of signal impulses comprising three groups is employed to operate the quotation boardapparatusrfor properly posting each quotation. Thesignal train comiprises .a selector group which selects the group of indicators in the quotation board allotted to the stock or commodity being c uoted upon and which :turther selects the proper range indicator, such as yesterdayh close, high, low -etc., a restoration group for bringing theisel ected indicators to a unison position, and an answei group for setting up the quotation on the indicators.

According to the'present .inventi'on we propose to 'use'the same typeiof signal .train to op- :erate the printing unit. -=Oneor-1nore of the digits representing the numerical pant ofa quotation is set up and printed by .a group of type wheels in substantially the same .-ma.-1-i-ner [as describedin-the aforesaid Hooverfet al. ap-

stituted for the last range indicator.

cluded in the selector group of the signal impulse train for the purpose of selecting the high, low or other set of range indicators in the system described in our aforesaid application. In our present invention this signal selects, in addition to the indicators, a circuit which will cause the special type character to be set up in printing position, according to whether the selecting signal is one which selects the high, low or other set of indicators. After being set up the special type character remains in printing position until after printing is effected. In the description of our invention a quotation board arrangement using special characters to designate the high and low range values only has been chosen as illustrative of the principles involved. The characters most commonly used are the letters H and L and these are used in the description. It is to be understood, however, that any other agreed symbols may be used instead of H and L to designate the range values.

Referring now to the drawings we show in Figs. 1, 2,'and 5 the preferred form of the printing unit 10 in which a plurality of type wheel units 11 are employed forprinting the numerical-value of the quotation, and a special arrangement employing type carrying sectors 12 and 13 forprinting H or L, in addition to the numerical characters when such quotation represents a high or low value.

L. This mechanism includes, in its pre ferred form, the pair of sectors 12 and 13 pivotally mounted on the shaft 14, which shaft. also passes through the axis of the i type wheels. The sector 12 is arranged to carry theletter H on a face formed at the outer endthereof and the sector 13 the letter L on a face at theouter end thereof. The sectors are arranged to carry their charactors in line with characters on the rim of the type wheels, or in such position that when the sectors are set in printin aosition the characters will be on substantially an even line with the characters presented by the type wheels. A pair of operating magnets 15 and 16, one for each sector, are supported at the outer end of a framework 17 and are arranged to swing the type carrying sectors into and out of printing position. The magnets 15 and 16 each have similar, pivotally mounted'armatures 18 and 19 joined respectively to arms 21 and 22 extending back toward the axis of the sectors 12 and 13. The

sectors have arms 23 and 24 extending from the pivotal axis of the sectors to engage the actuating arm of the respective magnets. The actuating arm of each magnet and the arm of the corresponding sector are operatively connected together by a pin 25 and slot 26 or other suitable connection.

The H type character is carried by the sector 12 normally held toward the front of the quotation board when out of printing position and is connected through the arms 23 and 21 to the actuating armature 18 of the upper magnet. The type character L is carried by the sector 13 normally held away from the front of the quotation board when 3 it is in non-printing position and is connected through the arms 24 and 22 to the actuating armature 19 of the lower magnet.

The arrangement is such that when one of the magnets is selected, it receives an operating impulse which causes the armature to be drawn inwardly toward the core of the magnet carrying the actuating arm upward or downward, as the case may be, which corresponding type carrying sector with it and rotates the sector about its pivoted aXis to bring the sameinto vertical position presenting the type character on line with the characters of the type wheels. At the outer end of each type sector is a projecting lug or arm 27 which engages a notch 28 in a dog 29 carried by a rack member 31 and held down by a spring 32. The notched dog 29 is arranged to hold the type carrying sector 12 or 13 in a vertical position against the tension of a spring 33 tending to return the actuating arm 21 or 22 to normal position. The dog is arranged to maintain the sector in a vertical position until the rack 31 is moved upward against the tension of the spring 32 allowing the lug 27 to escape; This rack is moved to disengage the dog by the printing mechanism at the end of each printing operation, as will be presently explained.

Any suitable type of type wheel may be employed for printing numerical part of the quotation. For the purpose of illustration, We have shown in Figs. 1, 3, 4 and 5.

type wheel units similar to that described and claimed in the copending'application of R. Hoover entitled Stock quotation boards. filed April 3. 1931. Serial No. 527.588, and assigned to The lVestern Union Telegraph Company. Each unit comprises a framework 35, a type wheel 36 carried at one end of the framework, and an operating magnet 37 carried at the other end of the framework. The type wheel 36 is rotatably supported on a hollow sleeve member 38 exste'mlinggfbetween the side'sgil and 4. 1501 the framework.

,carrying sectors 12 and The sleeve inember'. 38 surrounds the shaft orstay rod member Meir tending between thexsiicles 43 and 44 of the printing unit housing. 'lhe stay rod 14 also forms the pivotal axis of the special type A ratchet Wheel 4'5 is mounted. co-axially with'the type wheel atone side thereof and a control commutabrushes 47 and 481at the other side thereof,

tor 46 (Fig. 4%) with suitably connected 7 both being operatively connected to the type wheel. p

Each type wheel has eleven flat faces formed on its rim. Ten of the faces bear the numerical characters 1 1509. and .0, one

of the faces being blank. The :type'wheel rotates in a counterclockwise direction as viewed in Fig. 33;, and is rotated in a step by step movement produced by means of a pawl arm operated bythe actuating magnet 37 and a. pair of pallets '52 and 53 car- I a ried by the pawl arm which alternately engage the teeth on opposite sides of the ratch et wheel 45. l V 1 When it is desired to print from the type wheels they may befirst restored to a predetermined unison position, which is, preferably, with the blank'face of the type wheel in printing position, and then set in the cor "rectposition'for printing the'desired char- I acter by transmitting to each operating magnet a number of impulses equivalent to the number of the digit which it is desired to print from the corresponding type wheels. It is obvious that the mechanism as heretofore described for supporting the various characters and moving them into printing position, such mechanism including type wheels bearing the numerical characters and the sectors bearing the letters H and L', will serve equally to bring the desired'characters into display position before apertures provi-d' ed in' a display panel as forsetting the characters nto; printing-position 111 a printingunit. To employ the mechanism in a display or indicator unit it would be necessary merely to dispose the special type carry ing sectors or bars so that the desired special character will be moved into position before an aperture in ,a,display panel when 'oper-' ated by the proper signal. The type'wheels also can'be adapted for such use by 'I'nerely so disposing the commutator and character wheel that when the wheel is set in the'unison position of the wheel and'the display position of the character's, therewill occur suitable apertures in the display panel in-- stead of before theprinting platen of the printing unit as hereinafter described v The quotations are printed'on a record tape 54:,sl1ownin Figs. 1 and 2. 'Itis preferably a strip of'paper of suificient width to receive the desirednurnber of characters representing the quotation. It may he supplied from a roll 355 suitably mounted between the sides oiithe printingunit housing. From the supply roller it. passes oyer ameteringroller 56, thence overan idler roller .57, through an opening or slot 58. tothe froirt. of the (piotation board. The metering roller and 'idler roller are arranged to hold asection of theztape: 54in a. substantially horizontal position between the printlength of the record tape after each print .ing-operation and is accomplished by means 10f the roller being provided with a :circu lk ference of a suitahie size to feed out the tape until the last quotation imprinted thereon appears in view at the front of. the quotation heard; The other function of the metering roller is that of lifting'the. rack '31 to unl ck the special type carrying sec-tor arm 21'; from the notched dog 29 iw'hen either H or has been printed. This is accomplished by means. of a pin 59 carried by the metering roller which strikes the lowerend 61 or the rack .31 asthemetering roller begins to re.- vlolve.

The printing mechanism, referred to above,

.lrc

comprises a series of platen blocks eI1- gaged by a universal bar ea which .is in turn secured to the plunger 65 of the solenoid 66 supported on a plate 67 carried by the hous ing. When the solenoid is actuated the core or plunger raises the universal bar and causes the'platens to carry the record tape 5411p against the type characters, which have been set in printing position, and imprint the quotation from the type lcharacters on the tape. .After imprinting the quotation on the I recordtlape, the platen and plungerof the solenoid are returned to their normal position by means of a retractable spring .68.

During the return of the plunger 65. to

normal position a series of mechanisms, 1:

shown inFigs. l and 2 'is operated which releases, themetering rollerand permits it to rotatea complete revolution in response to tension set up in a lower section ofthe tape by means of th'e take-up or receiving roller of a windin-gmechanismnot shown. Itwill be observed, by referringto Fig. 2,:thatthe metering roller is provided at one end with a stop cam 71 which is arrangedto permit the metering roller tomake only one revolution at a time. The cam has an inclined face portion- ZQJterminating with a shoulder 7 4.

A stop arm '7 5 is provided to rest against the shoulder 74: and-restrain the movement of the metering roller against the tension inclined face 78. A shoulder 79 is formed at the inner extremity of the inclined face. A spring 81 holds the stop arm normally in contact with the cam.

, A lever 82 is mounted on the bracket 77, pivoted at 83, and is arranged to be actuated by the movement of the solenoid plunger as it carries the platens upward during the operation of printing. The left end of the lever 82has a pivotally mounted click or dog 84 secured thereto and held against a stop pin 85 by means of a spring 86. The outer end of'the dog is arranged to normally rest in the notch'or shoulder 79 of the lower end of the stop arm.

Upon an upward movement of the solenoid plunger, the left end of the lever 82 will swing downward and the dog or click 84 will slide off the shoulder 79 and click over into.

contact with the inclined face 78 of the stop arm. Upon the downward movement of the plunger, the left endof the lever will move upward and, the dog, being now held rigid with respect to the lever by means of the pin 85, will slide up the inclined face of the stop lever and force the same to rotate in a clockwise direction around its pivot point, and cause the upper end to slide outward off the shoulder 74 of the metering roller.

-As the stop arm 75 slides off the shoulder 74 the metering roller is released and begins to rotate permitting the tape to move forward and, down the front of the quotation board. As the metering rollers rotates the pin 59 comes against the inclinedface 61 of thelower portion of the rack 31 and forces the rack 31 upward which simultaneously raises the dog 59 lifting the notched portion thereof from engagement with the arm 27 of such one of the type sectors 12 or 13, as had been set into printing position. As soon as the arm 27' is released one of the retractable springs 33 connecting through the pawl arm of thecorresponding type sectormagnet swings the sector out of printing position into the position shown in Fig. 2 of the drawm s. r

y is the metering roller 56 continues its revolution theupper end of the stop arm 7 5 is held in contact with the inclined face 72 of the stop cam and follows the face of the cam as the same rotates with the metering roller until the upper end of the arm is again brought in engagement with the shoulder 74,

arresting the metering roller in this position. It will be observed, therefore, that the metering roller is automatically brought into action atthe end of each printing operation and performs the two functions as outlined above, that of unlocking either of the special type carrying sectors 12 or 13 that may have been set into printing position and of permitting, at the same time, a definite predeter-- mined amount of the tape to be fed out toward the front of the quotation board in order to bring the last printed quotation into view. 1

Referring to Fig. 6, we have shown another embodiment of our invention in which both of the special type characters, H and L, are carried by one sector 90 which takes the place of the two sectors 12 and 13 in the embodiment already described. The sector 90 is provided with two protruding faces, 91 and 92 separated by a recessed portion. Upon the faces 91 and 92 the characters H and L respectively are mounted. At the upper part of the sector 90 are provided two arms 27 which are arranged to engage the notch 28 in the dog 29 as the type character disposed opposite the respective arms is tension 98 of the framework 17, and has the double armature 9697 formed on its outer end. A pair of magnets 101 and 102 are provided for actuating the armatures 96 and 97 respectively to move the arm 94 up or down. The magnet 101 is arranged to beenergized in response to the high range signal to attract the armature 96 and carry the arm 94 upward to bring the face 91 hearing the character H into printing position, simultaneously locking the arm 27 in the notch 28. As the arm 94 is moved upward it carries with it the outer end of the leaf spring 108 which bears on its upper side. Upon release of the sector 90 the spring 103, which was carried upward when the sector was set in printing position, will now act to return the arm 94 to its normal or central position. This position is determined by pin 105 set in the framework 17 and arranged so that leaf springs 103 and 104 come to rest on opposite sides of the pin thereby holding the arm 94 in a normal alignment with the pin.

A signal impulse received by the magnet 102 will actuate the armature 96 and through the lever 94 act to set the L character on the face 92 of the sector 90 in printing position. To accomplish this the arm 94 swings downward carrying with it the outer end of the leaf spring 104 and rotates the sector 90 in a counter-clockwise direction to a posi tion where the corresponding arm 27 of the sector engages in notch 28 of the dog 29.

The answerzgroup of impulses follows the restoration group to .setthetypewheels with theproper digits in pr nt ng position. However, "before thetype wheels canbe moved from; their unison position itvisnecessary to establish a ground circuitfertile-magnets.

This is accomplished by means of a relay notshown, Wlnch connects the. Wire 134to the actuating grounder to a grounded contact; This establishes a ground circuit from the magnets throughthebrushes fl, the outer segmentsoi the commutatorsf-lfi, and the brushes-48;which are connected- 50 the line- 134.

I As a result, as soon as the answer signals beginthe several type wheels Willbe stepped dv by 11162111801? thegactuating magnets thateach'of the magnets is provided witha 1 inner brushes 4.7 are again brought in contact with the inner grounded segment of the commutators and will thereafter be grounded through the commutator axes and the grounded wire 133.

i For setting up our assumed quotation- H27 .3, three answer impulses are transmitted to the stepping magnet of the fractions type wheel which steps it around to place the digit 3 in printing position. Similarly, seven 1 answer impulses are transmitted to the units type wheel to step it around to place the.

digit 7 in printing position. Two answer signal impulses are transmitted to the tens type wheel to set the digit 2 in printing posi tion. The H character having been set into printing position by the rotation of the H i type character as described above, the printing unit will have been set up to print the assumed quotation. I i The printing operation is accomplished by the platen 63 being brought up against.

the faces of the type characters to. simultaneously print all the characters on a suitable paper tape. The actuation of the platen is brought about by means of the completion of a prepared circuit, which takes place upon the release of stock relay 119, accomp'lishcd at the end of the transmission of the train of signal impulses. The circuit was prepared at the beginning of the transmission of the quotation when the stock relay 119 closed the multi-contact switch 121,

thereby actuating relay 131 by applying battery 132 thereto. The actuation ofrelay r 131 connects its tongue 135 with the line 136 r to apply battery 129 through relay 128. When relay 128 is actuated it closes contacts 137 and 138. The closing of the contact 138 establishes a locking circuit from batteryv 11427 through the relay to the ground. The

closing of the contacts 137 establishes a ground circuit through the windings of the platen actuating solenoid-66. The other wire leading to the solenoid'66 normally connects a through the tongue 135 to battery 129. However, when the relay 131 was actuated and tongue 135 connected with. the wire 136, the circuit from the solenoid to the battery was opened. On the other hand, at the end of f the transmission of the train of signal inipulses when the relay 131 isreleased, the circuit is reestablished to the battery 129 and,- ground having been applied'to the other terminal of the windings of the' solenoid 66,

the solenoid is then actuated to raisethe plunger and bring the platen 63 with the interposed record tape up against the :face of the type characters to effect printing. The quotation having been printed the solenoid is deenergized to permit the platen to lower again to its normal position. This is accomplished by interrupting the circuit through thesolenoid windings and battery 129. A switch 139 is provided in the holding circuit for the relay 128 and means are provided for the plunger 65 to open the switch and release the relay 128 as the plunger 65 makes its upward stroke. The release of the relay 128 opens the contacts 137 which interrupts the ground circuit to the solenoid, thereby disconnecting the battery 129 and opensthe contacts 138 which interrupts the holding circuit of the relay 128 at another point to maintain the circuit open after switch 139 is permitted to close as the solenoid plunger returns to normal position.

The platen having made its upward stroke to imprint the quotation on the tape and returned to normal or rest position, there remains the additional operation of releasing the type sector which was set in printing position by the actuating magnet 15, before the printing unit is in condition for the reception of the next train 01": signals for posting the succeeding stock quotation. This release 1S accomplished, as already described,

manner, as just described in connection with a quotation including the letter H. For printing a quotation including L, the main L relay 114. will be actuated to apply poten tial from the line 110 through normally closed contacts 113 and contacts 115 closed when the relay was actuated to the low bus line 120. From the low bus line 120 the auxiliary L relay 141 is actuated, applying a locking circuit for the former through contacts 142 and connecting the line 126 through contacts 143 with the actuating magnet 16. As already explained in connection with the actuation of the auxiliary H relay 122, the line 126 has battery potential applied thereto which energizes the actuating magnet 16 to set the L type sector into printing position. The setting up of the type the quotation and the printing operation will be accomplished in the same manner as described in connection with the quotation assumed above.
