HASELTON, OF RYE, INEVV YORK, ASSIGNOR TO THE TELEREGTSTER CORPO- RATION, -OF NEW YORK, N. Y., A CORPORATION OF DELAVARE ELECTRICAL SIGNALING Griginal application filed. January 6, 1928, Serial No.- 244,873. Divided and this application filed January 6, 1930, Serial No. 418,801.

This invention relates to electrical signaling and more particularly to signaling apparatus and methods such as described in my application Ser. No. 244,873, filed January 6,,

at each of which quotations of stocks which are there of particular interest may be automatically posted on a bulletin board, the information being preferably made available, generally speaking, in the same arrangement as with the conventional types of manually attended stock boards, or black boards as heretofore used. However, with the apparatus of this invention the posting of quotations may be accomplished with greater rapidity and accuracy than with stock boardsjwhich are manually attended and in addition a substantial saving of labor is made possible since the equipment for numerousbrokers may be operated fromthe central point by'a single operator or group of operators.

The objects of my invention generally include the provision of apparatus of the above indicated class which will be adaptable with a wide degree of flexibility to various operating conditions and which will be accurate, rapid and dependable in \operation.

One object ofthis invention is the provision of means ,for restoring and/or actuating one or more indicators of a group of indicators simultaneously.

Another object is the provision of means for restoring corresponding indicators of several'or all of the groups to zero simultaneously.

Further and more specific objects, features I and advantages will-clearly appear from the Renewed May 6, 1932.

following description taken in connection with the accompanying drawings and claims which form a part of this specification.

The invention comprises the novel signaling methods, features, circuit arrangements, and combinations of circuits and parts as hereinafter described, but by way of example only, as illustrative of certain preferred embodiments of the invention.

In the drawings, Fig. 1 shows two sections of the transmitting tape;

Fig. 2 shows a polarity selection chart;

Fig. 3 shows the transmitting mechanism; Fig. 4 is the wiring diagram for the mechanism shown in Fig. 3;

Figs. 5 and 6 taken together show the wiring diagram for the selection, restoration and actuation of the various indicators;

Fig. 7 shows the thousands selector;

Fig. 8 shows the hundreds selector;

Fig. 9 shows the off-neutral switch in the hundreds selector;

Fig. 10 shows a detail of the contact mechanism of Fig. 8; and

Fig. 11 shows the mechanism for connecting several or all of the groups of indicators to the transmitting mechanism.

With the conventional forms of manually attended brokers boards, provision is ordinarily made for posting the quotations of numerous stocks, commodities, or other items, each quotation generally comprising four digits, namely, the hundreds, tens, units and a fraction value. The brokers customers are generally desirous of knowing the open,

high, low and last quotations for each stock or item, and accordingly, it is customary to provide space for such quotations, that is, for a total of 16 digits in'all for posting the quotations of a single stock or other such item.

In order to electrically control the indicators at a plurality of brokers offices-from a distant point, it is economically impracticable with the prevailing line wire costs, to provide separate line connections for giving quotation service for each of the multitude of listed stocks. Accordingly, it'is desirable to provide means for sending current varlations representative of the quotations of numerous stocks over a relatively small number of line wires, and to provide selecting means at each brokers oilice to identify the quotations of particular stocks and to prepare the corresponding indicators for energization. How= ever, in thus reducing the number of line Wires to a' relatively small number, special attention must be directed to the necessary rapidity of operation of the indicators. Taking into account the reasonable future requirements, provision should now be made in an apparatus of this class for sending quotations for more than a thousand different stocks or items, each of which must be individually identified by the selecting means. After such identification four digit indicators preferably should be actuated to show a particular quotation, and in the event that the high or low quotations are to be s1- multaneously set up, then as many as eight digit indicators may be actuated. With stock market transactions conducted at the present rate, provision must be made for transmitting from 30 to 60 new quotations per minute. Such speed of operation of a multitude of indicators at different offices, but all selected and actuated in a dependable manner over a relatively small number of line wires, necessarily requires novel circuit arrangements which have no counterpart in other classes of signaling apparatus.

According to my invention I have found it desirable to provide for each unit of signaling apparatus four line wires or equivalent impulse channels which are associated with a common ground return circuit, and may be utilized first to simultaneously operate our selecting devices for choosing one particular stock to be quoted. Thereafter the same four line wires or impulse channels may be conveniently utilized to simultaneously, but independently actuate the four digit indicators of a particular quotation, that is, for example, the hundreds, tens, units, and fractional digit indicators, if all of these need to be changed.

The current variations or impulses for selecting and actuating the indicators may take eitherv the form of positive spaced impulses, or may be in the form of undulations or interruptions in a sustained potential applied to the line wires. With the particular form of selecting devices described in connection with the example of the invention herein disclosed the latter method is followed, that is, the distinctive current variations comprise short interruptions or reductions in the line wire potential. The selecting devices may be constructed with a sufficient number of contacts so as to select not only the desired stock but also the articular quotation as the open, high, low or last, which has to be changed, or on the other hand, only a smaller number of selector contacts need be provided where the selectors merely choose the particular desired stock. According to the embodiment of my invention herein described, I have provided means whereby one of the quotations, either open, high, low or last, or combinations thereof, are selected merely by the polarities of the several line wires. That is, the sustained potential applied to each line wire may be relatively positive or negative in respect to the other line Wires, andaccordingly, numerous combinations of polarities may be obtained, sufficient in number to readily choose between the open, high, low and last indicators and combinations thereof, thus materially reducing the work to be done by the selecting devices and the time necessary for the operation thereof. Use is also made of different polarities on one of these lines to establish restoration and actuation paths for the impulses transmitted to the indicators.

The method of using a maintained line potential not only simplifies the selecting problem in this manner but also makes possible in a simple manner the use of an adaptation of the well known Strowger up and around selecting devices as are Well known in the art of automatic telephony switching. The construction and operation of such selectors is set forth in detail, for example, by H. H. Harrison in his book entitled Automatic Telephony, published in 1924: by Longmans, Green & Co., and also by R. G. Kloefller in Telephone Communication Systems, Macmillan Co. 1925, Chapter XIV, and accordingly the constructional details of such selectors will not be here fully described, although such features as are necessary to adapt the same to my invention are hereinafter fully disclosed. Since this type of selector automatically restores itself to a normal position upon any extended interruption of the line potential, such selectors are particularly desirable for use with this invention inasmuch as such restoration to normal after each operation substantially precludes all possibility of cumulative errors or false quotations on the'multitude of indicators.

This invention comprises a transmitting mechanism such as shown in Figs. 3 and 4 in the transmitting station, a plurality of line wires extending from the transmitting station to the receiving s'tation or stations and mechanism in the receiving station such as indicated in Figs. 5, 6, 7, 8, 9 and 10. The selection of the various groups of indicators and the indicators within the groups and the restoration and forward actuation of the indicators are all made by various electrical impulses sent from the transmitting station over a number of line Wires L L L L F or the purpose of imposing combinations of positive and negative polarities on these line wires and for the purpose of interrupting these potentials, suit able switch mechanism such as shown in Figs. 3 and 4 is provided. These switches may be controlled by manual means such as keys but in the form shown therein they are controlled by a tape such as shown in Fig. 1. This tape is shown as provided with nine fields to receive perforations. The fifth field controls an on and off switch 15 Figs. 3 and 4) to connect lines 16 and 17 wit positive and

negative potentials

18 and 19 shown in Fig. 4. Cooperating with this field is a sensing pin 20 (Fig. 3) carried by a switch throw bar 21 pivoted on an arm 22 which is rocked back and forth by a disk 23 through a link connection 24. The free end of the throw bar 21 will be in the position indicated when the pin 20 cooperates with a blank portion of the field. If the switch 15 at this time is in the off-position, the bar 21 upon movement to the right, will throw the switch into the onposition. If a perforation is opposite the sensing pin the free end of the bar 21 will be lowered to throw the switch into the'oifposition. Cooperating with the lower end of the switch 15 is a spring-pressed roller 25 which will hold the switch 15 in either on or off position when there is a succession of blank spaces or a succession of perforations. Cooperating with the

fields

1, 2, 3 and 4 of the tape are switch members 26 (Figs. 3 and 4) similar in construction to the switch member 15 and adapted to connect the lines- L L L L; with either source of potential, to impose positive and negative potentials on these lines in various combinations. Cooperating with the

fields

6, 7, 8 and 9 of the tape are switches 27, which are interposed in lines L L L L.. These switches are normally held closed by springs 28 but are opened by mechanisms similar to the mechanisms controlling the on and off switch, and the polarity selector switches whenever the controlling sensing pins 20 pass through perforations in the tape. The spring 28 is provided so that the switch 27 will return to closed position as the bar 21 is moved to the left.

By means of the mechanism so far described, the field 5 of the tape will control connection of the lines 16 and 17 to the source of positive and negative potentials. The mechanism cooperating with the

fields

1, 2, 3, 4 will Selection of main indicator bus lines and conneetion therewith of the corresponding restomtion bus lines The various potentials imposed on lines L L L L; by the switches energize selecting magnets 30, 31, 32 and 33 (Fig. 6). Line L is extended through the coils of magnets 30 and 31 and line L is extended around the coils of magnets 31 and 32. The operation of these two magnets is to effect selection of indicators within a group of indicators by connecting the various bus lines last, low, high and open, with main actuating lines B B B 13,. Line L is extended through the coil of magnet 32 which controls the selection of restoration and actuation busses for the indicators. Line L is extended through the coil of the magnet 33 and the coil of the magnet 30. The magnet 33 connects the various selecting switches and magnets to the battery.

As the tape at the left in Fig. 1 is fed past the sensing pins, positive potentials are set up in lines L and L and negative potentials in L and L Line L energizes the magnet 33 which through its switch 34 connects the switch system to the battery. The potentials on lines L and L being of like sign the magnet 32 will be energized and its switch member 35 will be drawn into the position shown to complete a circuit from the battery through the restoration magnet 36 connecting all the restoration bus lines to the main bus lines for the last, low, high and open indicators. The positive potential on line L and the negative potential 011 line L will have no effect on the magnet 31 and, accordingly, its spring switch 38 will remain in the position shown. The positive potential on line L.

and the positive potential on line L. will cause energization of the magnet 30 and 010s ing of the open switch 39 and opening of the closed switch 40. This completes the circuit from the battery through switches 34, 38, 39 to low magnet 41, which connects the main low bus wires to the main actuating wires B B B and B The potentials imposed on these lines have therefore connected the restoration bus lines for the low indicators, to the main actuating lines B B B B The last, high and open magnets 42, .43 and 45 are controlled respectively by p'otentials as shown in Fig. 2.

Selection of groups of indicators I Inreferring to Fig. 5 it will be noted that the potential on line L has energized magnet 45 which has attracted its spring switch 46 to complete a circuit from a battery through the coilof a'slow-to-release magnet 47, and the spring switch 46 to the ground. The polarity imposed on line L has energized magnet 48 in the hundreds selector which has completed through its spring switch 49 a circuit from a battery through the coil of a slow-to-release magnet 50 to the ground. Similar magnets in the tens selector and units selector have been energized, but the description of the select ng mechanism will be limittively asthe tens and units selectors. As the perforations in the group marked Group selection in Fig. 1 pass over the impulse sender pins shown in Fig. 3, the potentials over lines L L L L are interrupted. Considering, first, the interruptions of potential in line L, the effect of an interruption is to de-energize the magnet 45 so as to complete a circuit from the ground through spring switch 46, spring switch 51, spring switch 52 of magnet 47, through the coil of the slow-to-release magnet 53, and the coil of the vertcal stepping magnet 54, which is shown as a pair of magnets in Fig. 7, to a battery and ground. When the magnets 54 (Fig. 7) are energized they will attract the movable armature 55 carrying a spring pressed pawl 56 cooperating with teeth 57 on the thousands selector shaft 58, to raise this shaft one ste for each energization of the magnets 54. s the shaft 58 is raised its shoulder 59 perm ts the

switches

60 and 61 to close and rema'n closed as long as the shaft is in elevated position. An interruption of the potential on line L de-energizes the magnet 48 in the hundreds selector and establishes acircuit from the ground through spring switch 49, spring switch 62, spring switch 63 of slow to release magnet 50, co'l of the slow to release magnet 64 and coil of the stepping magnet 65 to the battery and ground. The energization of the magnet 65 in Fig. 8 operates a pawl 66 cooperating with a ratchet 67 on the hundreds selector shaft 68. This shaft carries a grounded switch arm 69 which is moved over a series of contacts 70 as the shaft is rotated. The shaft also carries off neutral switches 71 and 72 (Figs. 9 and 5) which are constructed to close and rema n closed as long as the shaft 68 is out of hom position. After the interruptions over lines L and L have ceased, that is when the vertical adjustment of the shaft 58 in Fig. 7 and the angular adjustment of shaft 68 in Fig. 8 have been completed, the cessation of interruptions of potentials on line L will cause the magnet 45 to rema n energized, wh ch will maintain the magnet 47 energized and prevent further energization of magnets 53 and 54 and causes the slow to release magnet 53 to de-energize. Energization of the magnet 47 has drawn its switch member 73 to complete the circuit from the ground battery, switch member 73, coil and shunt of magnet 74, switch member 75, switch member 76, switch 61 through the col of magnet 77 to the ground, thus preparing a circuit through the switch member 78 of the magnet 77. The cessation of impulses on line L maintains the magnet 48 energized which maintains the circuit over the magnet 50 and breaks the circuit over the magnet 64, which closes a c rcuit at the point79. As the magnet 53 in the thousands selector de-energizes, it closes-a circuit from the battery over the switch 73. switch 80, switch 78, over the coil of the horizontal stepping magnet 81 (Figs. 5 and 7), over the switch 71 in the hundreds selector, switch 79, and switch 82 of magnet 50 to the ground. This energizes the magnet 81 which attracts its armature 83 and through a pawl 84 carried by it and in engagement with a ratchet drum 85 on the shaft 58, rotates the shaft one step. The movement of the armature 83 breaks the switch 76 which breaks the circuit through the magnet 77 thus breaking the circuit through the magnet 81. When the circuit through the magnet 81 is broken the switch 76 again completes the circuit through the magnet 77 wh ch in turn completes the circuit through magnet 81.

Secured to the shaft 58 in Fig. 7 are two

contacts

86 and 87 which are adapted to cooperate respectively with pairs of fixed

contacts

88 and 89. When the shaft 58 is elevated by interruptions over line L as previously described, the

contacts

86 and 87 are raised into alinement with a horizontal row of

contacts

88 and 89. As the magnet 81 is energized and de-energized to rotate the shaft 58 these contacts are moved along the selected row of cont-

acts

88 and 89 and the energization and tie-energization of the magnet 81 is continued until the contact 86 finds a live contact 88 which is grounded through one of the contacts 70 (Fig. 10) and the arm 69. When this occurs the circuit over the magnet 77 will be shunted and the magnet 74 (Fig. 5) will be energized to attract its switch and prevent further energization of the magnet 77. This in turn prevents completion of the circuit through the magnet 81 over the switch member 78. Energization of the magnet 74 also moves the switch member 51 to connect the line B through switch members 51 and 46 to the ground. Energization of magnet 74 also attracts its switch member 91 which extends a circuit from a battery over switch member 91,

contacts

87 and 89, selector line 92 to a panel board (Fig. 6). One of the tens selector lines 93 has been connected by mechanism similar to that in the thousands selector through a switch 94 to the ground. The selector line 92 at the point of intersection with the line 93, is connected by one side of a double plug to a line 95 extending over the coil of a group selector magnet 96 and then over line 97 to the other side of the plug to the line 93 and to ground. This energizes the magnet 96 and selects a group of indicators corresponding to the adjustment of the selectorsin Fig. 5 under the control of the impulses caused by the group selector perforations in this section of the tape at the left of Fig. 1. Each of the indicator elements of the indicator units of the groups of indicators is diagrammatically indicated at 99.

When the circuit was made at 79 in the hundreds selector the magnet 98 in the hundreds selector was energized by a circuit from ground, battery, coil of the magnet 98 over switch 71, switch .79, switch 82 to ground. Energization of the magnet 98 attracts the switch member 62 and connects line B through the switch member 62 and switch member 49 to the ground, upon de-energization of magnet 48 by. interruptions on line L In the same manner lines L and L are connected respectively to lines 13 and B in the tens and units selectors.

By means of the mechanism so far described the impulses sent over the linesL L L L have caused a selection of a group of indicators, of an indicator within the group, and have connected these lines with restoration busses for these indicators, and as the tape in Fig. 1 is moved to present restoration perforations to the impulse sender pins in Fig. 3, the impulses sent over the lines L,, L L L will cause corresponding impulses over the lines B B B B and over the restoration bus lines to the selected indicator to move the indicator elements of the selected indicator to zero. By means of a known construction, as stated in the parent application, and a structure similar to that shown in the patent .to F rischknecht et al., 1,852,994, dated April 5, 1932, the circuits leading to these indicators will be broken at the time the indicators reach their zero positions. After the selected indicator has been restored to zero, the tape will be advanced and the third field in the tape will present blank spaces to its sender pin to throw positive polarity on the line L This will cause desenergization of the magnet 32 in Fig. 6 which will release its switch member 35 and connect'the battery to the magnet 100, which will connect the main bus lines to the forward actuation bus lines. As the tape is moved farther to present the actuation perforations to the impulse sender pins, impulses will be sent over lines L L L L and the resulting impulses over lines B B B B will pass over the indicator actuating bus lines to the selected group of indicators and the selected indicator in the group. This will actuate the indicators forwardly an amount determined p by perforations in this section of the tape.

The restoration and actuation of the selected indicator is now complete and when perforations in field 5 are presented to the on and off switch member of Fig. 3, the positive and negative sources of polarity 18 and 19 (Fig. 4) will be disconnected from the lines L l L L This will cause the magnet in the thousands selector (Fig. 5) to be tie-energized, which causes the deenergization of magnet 47, which in turn causes l(--cnergization of magnet 74,and alltheparts will be restored to the position in which they are shown in the drawings. The same thing will occur in the hundreds, tens and unit selectors. After the magnets 45 and 47 have been de-energized a circuit will be completed from the battery through the release magnet 102 (Fig. 5), switch 60, switch 52, switch 51, and switch 46 to the ground. Energization of the magnet 102 in Fig. 7 attracts its armature 103 and disengages holding prongs 104 and 104' from the

ratchet members

57 and 85 of shaft 58. This will permit the shaft 58 to be rotated to home position by a spring 105 and to drop under the influence of gravity to vertical home position, and asit drops into its home position the shoulder 59 engages an operating lever 106 to break the switch connection 60 and 61 (see also Fig. 5). All the elements of the thousands selector are now in home position. In the hundreds selector deenergization of the magnets 48, 50 and 98 completes a circuit from the battery through the release magnet 107, through contacts 72, switch 63, switch 62 and switch 49 to the ground. This energizes magnet 107 (Fig. 8) which withdraws the releasing pawl 108 from the ratchet 67 on the shaft 68 permitting the spring 109 to return the shaft 68 to its home position. The same thing occurs in tens and units selectors.

Combination selection 0 f indicators It may at times be desirable to restore and actuate a plurality of indicators in a group. For this purpose the line L is branched over the coil of the polarized magnet 110 which is responsive to negative impulses from line L \Vhen the magnet 1.10 is energized it prepares a circuit from the low and high magnets 41 and 43 over the

switch members

111 and 112 over its own switch 113 to the circuit which controls energization of the last magnet 42 of the last switch member 114. WVhen the polarity on line L is negative and either the low or the high bus line is selected, the last bus line will be selected simultaneously. Referring to Fig. 1 a section of the tape at the right of this figure is perforated to select the low and last bus lines to control the restoration and forward actuation of the low and last indicators in a selected group.

Group restoration One or more of the selector circuits, for example, the one corresponding to the number 9999, may be employed to control the operation of all the group selector switches 96 simultaneously. The

selector circuit

92, 93

for this number may energize

magnets

115 and 116 as shown in Fig. 11, to connect all of the lines 92 to the battery and all of the lines 93 to the ground. If desired, several relays may be provided to permit of the restoration of less than the total number of groups at one time.

Other selector circuits

92 and 93 would be allotted to this purpose. If desired also the switch controlled by the magnet 115 may connect all of the magnets 42, 41, 43 and 44 to the battery to connect all of the bus lines to the lines B B B and B to restore all of the indicators to zero simultaneously.

For the purpose of restoring all or several of the corresponding indicators of the various groups of indicators to zero, the tape may be provided with perforations to control the selection of one of thefour bus lines, and selection of the selector circuit such as 9999, and with restoration perforations, so that all the indicators which are connected to the selected bus line may be simultaneously turned to zero. In like manner, the other three or four bus lines may be selected and the respective indicators turned to zero. If desired several of these bus lines may be connected to the main actuating lines B B B B as eX- plained, so that two indicators in eachof the selected groups may be turned to zero simultaneously. The term register as used in the claims is to be construed to cover indicators or other posting devices including one or more elements.

While the invention has been described in connection with the embodiments illustrated, it will be understood that this has been done for purposes of description and not by Way of limitation, and that after an understanding of this invention, numerous modifications and changes may be made by those skilled in the art without departing from the spirit and scope of this invention.
