l to sale of `tickets or commodities, admissions, etc., which have been made at the different selling points. l

It frequently. occurs, for example, at public gathering places that tickets, an indication of the total of values of which is desired, are sold during simultaneous periods, with respect tothe different features of the exhibition and at a large number of widely distributed points and, further, that these tickets withv respect to each'ieature are sold in a number of`difierent values. Furthler the sales are frequently made by means of rapidly operating ticket vending machines at rates determined largely by the capacity ofthe machine itse f. a

One of the objects of our inventionvis to provide an electric system whereby the total value 'represented by all tickets sold and the. total value represented by tickets sold with respect g to each of the diierent features may be continuously indicated during the period in which sales are made. A further purpose of the invention is to provide such a system which is capable of operating with sufficient rapidity to indicate the above 30 .mentioned totals substantially simultaneously with the sales, that is, such that the totalswhich are indicated follow the progress of the sales with substantial accuracy, or with the degr'e of accuracy that is required, as by renderingthe indi- 5 cation in even hundreds or thousands. A furthe;` object of our inventionis to provide a system capable of accomplish-ingv the above result notwithstanding the rapid operationyof the ticket vending machines.-

40- Another purpose of the invention is to provide means whereby .the desired totals may be ,indicated by any suitable means as by means oi dials with cooperating pointers, or by means of a lamp, or by means of groups of lamps which are respectively controlled so that they are lighted so as to form the'digits of the quantity to be -indicated In the operation of the system tobe described,

as briefly stated, an electric impulse is produced 50 in response to each operation of .the different ticket vending machines. Each impulse therefore represents a vdefinite value which is to be included in the total. Means-are provided'where-' by all of the impulses from each group pista- 55 tions which transmit impulses representing equal means included in (Cl. 23S-92).

value are collected, without confusion of impulses, f

upon a single conductor and caused to actuate the totalizing equipment whereby all impulses produced by all of the ticket vending vmachines are reduced to impulses of equal value. These impulses of equal value are then automatically added toA produce an indication of the desired total in even hundreds, thousands, etc. as is desired.

' It will thus be apparent that, while we particularly mention the use of our invention-in connection withthe totallzing of the value of tickets sold at public places, exhibitions, theaters and the like, it is by no means maybe employed wherever may be produced in response value which is to b included in the total to be indicated. For example, our invention has utility in connection with the totalizing of the readings of integrating power meters. Each of the meters, the reading of which is to be included in the total, may be provided vwith means whereby an impulse is produced in response to each unit of power integrated by the respective meters. The Jimpulse transmittedin response to operation meters may represent different units of power as desired and the meters may be variously loan electric impulse cated. All of these impulses will then be causedl to each unit of of different' limited thereto andy to 'abtuate the totalizing equipment to be described whereby the total power integrated by all of the meters may be indicated.

Thus many other'applications of our invention will readily suggest themselves to one skilled in the art and all of such applications are contemplated as` within the scope of the present invention.

The novel features which we believe to be characteristic of our invention are set forth with particularity in the appended claims. Our invention itself, however, both as to its organization and method of operation, together with iurther objects and advantages thereof, may best be understood by reference to the 'following description taken in connection with the accomv stations, which in order to simplify the disclosure with each group ls an additional selector switch.

are shown as pairs of contacts, which may be controlled manually or by means of a device the operation of which represents the values which are to be included in the total to be indicated. Ac-

cording to the arrangement shown these contacts' are momentarily interrupted in response to each operation of the ticket vending machine, for example, or they may be momentarily interrupted at a rate determined by the rate of operation of a power integrating meter, or by any other suitable device not shown. Thus momentary interrup-f' tion of any pair of contacts represents a certain value which is to be included in the total. These contacts are arranged in groups in accordance with the values represented by the operation thereof. Thus, for example, assuming that the operation of contacts I or'2 represents a value of 2. These contacts and all other contacts, the operation of which represents this value, will then be included in a single group designated on the drawings as group 1. Similarly assuming that the operation of each oi' contacts 3 or 4 represents a value of 5 thenthese contacts and all contacts, the operation of which represents this value, will be included in another group desig-- nated on the drawings as group 2. Similarly the operation of contact 5 may be assumed to repre- Sent a value o f 10, and the operation of contact 6 a value of 50. For reasons which will later be indicated we have included these contacts in a single group designated on the drawings as group 3.

It will be apparent` as the description proceeds that operation of the different contacts may represent any desired value, the circuit adjustments necessary in any case being obvious toone skilled in the art. For the purpose of illustrating the operation of the system without unneces-4 sary complication of the drawings, and not in any way..to limit the protection herein claimed, the above values are assumed, but three groups are indicated, and further, only two contacts in eachV group are illustrated.

It will be noted that each contact I, 2, 3, etc.

lhas associated therewitharelay I', 2', 3', etc.

is controlled by any of the relays associated withA contacts in its respective group. Also associated A', B' which functions as a counting or adding device. Each of these selector switches consists of a plurality of semi-circular banks of contacts each of which has a cooperating Ywiper associated therewith. These wipers are connected to a` common shaft and are adapted to be moved in a step by step manner over the contacts in their respective banks inv response to the energization and deenergization of a suitable driving motor magnet which is associated therewith. While the number of contacts in each bank may be any desired number, usually they are constructed in practice vwith 25 contacts in Y each bank.

ASwitches of this type are well known in the lart and one constructionwhich may be employed is fully disclosed in Letters Patent 1,472,465 to 0,'11.` Forsberg, granted October 30, I1923. While we have shown selectors of the'well-known rotary type, itl will be obvious to those skilled inthe art be used. 'I'he arrangement shown in the drawings is suchthat upon operation of any contact or combination of contacts in any group causing the operation of the associated relay I', 2', 3', 4' the respective collecting switch A, B rotates over its entire bank of contacts and transmits an Impulse to the adding switch A', B', of the respec-r. tive groups corresponding to each of the contactsV i, 2, 3, 4 which have been operated. T hus, `for example, if all oi' the contacts in group I were operated simultaneously collecting switch A would rotate over its contacts and transmit' an impulse. to the motor magnet 'I of adding switch.

A', for each of the operated contacts in group I, thus causing this adding switch to step forward a corresponding number of steps. In the particular arrangement shown each .of the switches A, A', B and B has three banks of 25 contacts. The normal and each successive fth contact of the bank A-I of the adding switch A' are connected together and in circuit with a relay 8 which is actuatedwhenever the wiper engages one of these contacts. arranged to control an'additional relay 9 in a manner similar to that in which the contacts I, 2, 3, 4 control the associated relays I'2', 3'4'. Similarly the normal and every other contact of the bank B'-I of adding switch B' are connected together and in circuit with a relay I0, the contacts of which control an additional relay Il. Relays 9 and I! are connected to a collecting switch C in the same manner in which the contacts I, 2, 3, 4 areassociated withA their respective collecting switches A, B and, accordingly upon each operation thereof cause the collecting switch C which is similar in construction to switches A and B to operate over its entire bank of contacts thereby to supply impulsesthrough a conductor I2 to the motor magnet I3 of an addi A representsa value offv 2, it will be apparentthat the impulse transmitted by relay 9 through collecting switchC represents a value of 10. In

.the same way since relay II is operated in response to every other operation of adding switch B', it will be apparent that impulses transmitted by this relay through the collecting switch C represent values of 10. 'Thus all of pulses transmitted through the collecting switch C to the motor magnet I3 of adding switch C', represent equal values.

Switches C', D and E, each of which is similar in construction to switches A, B and C except that C' and D have ve banks of contacts and' E has four banks of contacts, are connected in cascade relation in the order mentioned; that is, these selector switches are so connected that upona' predetermined number of operations of each ot these switches an impulse is transmitted The contacts of this relay are Y to the motor magnet of the next switch in the operation of that switch, and upon each 10 vauch 'l5 predetermined operations of the switch D an impulse is transmitted to the motor magnet I 'l .causing a similar .operation of switch E. As

, be included in group 3, toa number determinedthe arrangement disclosed impulses which have vof the system a many additional switches may of course be included in the cascade connection as is desired. Thus it will be apparent that the switches C',

`D and E constitute a totalizing device for the received impulses. Since each actuation of motor magnet I3 Aof `adding switch C' represents y a value oi' 10, each actuation of switch D will represent a value of 100 and .each actuation of switch E will represent a value oi' 1000. Accordingly the total of values represented by operation of the keys I, 2, 3, 4' may be indicated 'in any desired number vof'digits by means of dials having cooperating pointers carried by the shafts of each ofthese switches.

Since operationof contacts 5 represents a value of 10 the associated relay 5' is connected to the collecting switch C in the same manner in which the relays I', 2', 3', 4' are connected t0 their respective collecting switches. eration of contact 6 'represents a value of 50, this contact is arranged to control five relays of which, to simplify the drawings, only two, 6' and 6" are shown. v.Each of'these relays is arranged to control the collecting switch C in the.

same manner in which the relays 5'; 9 and II control the collecting switch C. Thus, upon each operation of contact 6, the collecting switch C willltransmitve impulses to the motor magnet I3 ofI adding switch C'. Since contacts 5 and 6 may be caused to transmit impulses of equal value from their associated relays we have designated these contactsas included in a single group. .Similarly otherl contacts, the operation of which represents different multiples of 10, may

by the magnitude of the multiples and the capacity of collecting switch C.

It will thus be apparent that the function oi the collecting switches A and B is to collect the impulses rom the stations in groups land 2 respectively. The function of adding switches A' and B' is to add the impulses collected by the collecting switches A and B respectively and to transmit an impulse representing a predetermined multiple of the values represented by the impulses collected thereby each time thevalue of the total number of impulses received by the respective adding switch equals the predetermined multiple. Similarly the function of the collecting switch C is to collect all of these impulses representing this predetermined multiple and to supply them to the totalizin'g device' comprising the switches C', D and E. Since in a value less than 1,0 are not added to the total until a suflicient number of such impulses have been collected so that the value represented thereby is equaly to 10,. these impulses which rep-v resent values less than 10 may be called impulses of minor value1-and the impulses which represent the value lilimay be called impulses of V major value.

Having now generally indicated the character betterunderstanding thereof cmay Abe had by reference to its more detailed circuit arrangement and operation.

Referring to Fig. 1 of the drawings, with all of the equipment in the position illustrated, it

will be seen that y,relays I', 2', 3', 4', 5', 6', and 6" are all normally'energized through a hold# ing circuit including their inner. right-hand contacts and the contacts of the respective conture and deenergizingv itself, at the same time, Astepping the (wipers of each of the respective banks one step. Since'the outer righteliand contacts of relay I' Vare now separated the motor magnet vI9 will not immediately be energized when the collecting switch A is in the first off normal position. However, when the wiper oi the bank A-I engages its rst oi normal contact, relay I' is again energized through an obvious 'circuit thereby closing its right-hand contacts and energizing the motor magnet. I9 which in turnsteps the collecting switch to its second off normal contact. The second off normal contact of bank A--3 is connected through the outer right-hand contacts of relay 22.- which are now closed to the negative bus. Accordingly motor` magnet I9 is again energized and steps the wiper of the'bank A-'3 to the next 'contact which, to illustrate the operation Nef. the equipment, is shown permanently connected tothe negative bus I8. Thus the motor magnet I9 will actuate.

collecting switch A over its entire bank of contacts and return to its initial position where it will be deenergized by the outer left-hand contacts of relay I'.

When the wiper of the bank A--2 engages its rst off normal contact a circuit is momentarily Acompleted which extends from the negative bus I8 through the inner left-hand contacts of relay I' which are closed at this instant, erst cfr normal contact of bank A-2, contacts of relay 56,-motor magnet 'I of adding switch A' backjto the positive bus 20. lThus motor magnet '1 re-A ceives one impulse.

The manner in which impulses are. transmitted to the motor magnet 51 of adding switch QB in response to operation of' the contacts in group 2 is'the same as that which has been described in connection. with the operation of switches A' and A, and therefore will not be 4further related.

Since selector switches of the type employed in the system are ordinarily constructed with 25 contacts in each bank, it will now be apparent that there may be as manyas 24 stations included in either group 1 or group 2. It will be apparent that ifall of the switches in any group are operated simultaneously, the corresponding `collecting device, or v,selector switch A, B, will rotate through a complete cycle transmitting impulses in succession over the single conductor which connects the wiper of bank A-2 to the motor magnet 1, and at the s ame time restorirfg the corresponding' relays to the normal position where they are in readiness'fo'r the next operation.. Similarly the same will occur independently of theorder in which the contacts of any group are operated. All ofthe relays in any group are interlocked by-'means of their outer right-hand contacts to prevent any loss offimpulses. Thus, for example, assuming that collecting switch A is on its Vsecond off-normal contact due to operation of relay 2', when relay- I' is operated; it will rst energize'relay 2' and relay 9.

transmit the corresponding impulse to the motor magnet 1 after which it will return to the normal position. Since the circuit of the normal contact is completed by relay I' it will again rotate over its bank of contacts and restore relay I to the normal position` and send its impulse to the motor magnet 'I.

The normal contact and each successive fifth contact of the bank A'-I of adding switch A' are connected together and in circuit with relay 8 across the negative and positive busses 'I8 and 20. The armature of this relay 8, in either position thereof, engages one of two contacts which are connected together and which are included 'in the holding circuit of relay 9. Thus upon the first actuation of adding switch A' relay 8 is deenergized and its armature momentarily interrupts the above described circuit -for However, simultaneously therewithv a circuit is completed for relay 9 which extends from the positive bus 20 through the Wiper and `rst off-normal contact of the bank A-3 of ing the collecting switch C to complete its rota.

tron. 'Ihus it will be seen that one impulse repvhand contacts thereof to the negative bus.

Thus no operation of relay 9 occurs. This circuit is also `completed through the second, third and fourth off normal contacts of the bank A'-3. Whenthe adding switch A engages its fth off-normal contact, however relay 8 is again energized and momentarily interrupts the holding circuit of relay 9, and relay 9 is then deenergize for the reason that theabove described ci cuit through the wiper and contacts of bank A-3 is not completed when the wiper is in this position. Accordingly relay 9 will close its left-hand contacts and interrupt its righthand contacts. which extends from the negative bus through the outer left-.hand contacts of relay 9, conductor 2|, normal contact and wiper ofthe bank v C3 of collecting switch C and motormagnet 22 of collecting switch 'C to the positive bust When: the wiper of the bank C-2 engages its contact which is connected to conductor 23 an impulse will be transmitted through the inner left-hand contacts of relay 9, conductor 23,

.wiper ofthe bank C-2, conductor I2, contacts 'I2' on relay 56, and motor magnet I3 of adding switch C' to the positive bus.

Simultaneously therewith a lcircuit is com-- pleted through conductor 24 and wiper of the bank C-I of the collecting switch C, which in turn restores relay 9 to its initial position thereby applying neg'ativepotential throughits outer right-hand contact and conductor 25 to the corresponding 'contact of the bank C-3 andcausresenting a value ofl l is supplied'to the motor magnet I3. When the adding switch A' steps an additional step relay 8 is again deenergized and will remain' deenergized for four successive steps of the 4adding switch A' but relay 9 will not be operated for the reason',that its circuit is completed through the succeedingfour contacts, of

Since Vrelays I0 and Il, are Wired to the switches B' and C in the same manner in which the relays 8 ancl 9 are wired to theswitch A' and C.. their operation will not beA further described.

However, since each operation of the adding switch B' represents a value oi 5, every second on? normal contact on Abank ,B"-I is connected with relay III rather'than every fifthoi lnormal contact as inthe caseof the bank .A2-FI. II'hus A circuit will then be completedcomplete revolution.

tion of switch B', and therefore serves to supply impulses representing a value of through the bank C-2 and conductor I2 to the motor magnet I3 of adding switch C'. Since relays 5', 6' and 6" are wired to the collecting switch C in the same manner as has been described in connection with the other relays I', 2', 3', 4', 9 and II no additional description thereof is necessary, it being pointed out that there are ve relays 6', 6", etc. which are controlled by the contacts 6 such that upon each operation of contact 8 all of these relays are deenergized causing the operation of collecting switch C which in turn rotates restoring these relays to their initial position, and transmitting an impulse having a value of 10 from each of these relays to the motor magnet I3 of adding switch C.

In connection with the adding switch C it is to be noted that this switch has ve banks of contacts instead of three as is the case with adding switches A and B. The reason for this is that it is desired to transmit an impulse from this switch C' to the next switch D in the cascade arrangement in response to each 10 actuatlons thereof. As has been stated each bank includes 25 contacts. Thus, if the switch C'- were connected in the manner in which switches A' and B' are connected on ,receipt of twenty-live impulses the wipers of the switch C would be operated through one-half of a revolution. yBy arranging the wipers of banks C'-I and C'-2, and C' 4 and C'-5 to extend in diametrically opposite directions and by connecting these wipers together these banks may be made to perform the' function of a single circular bank having 50 contacts. Thus upon receiptof impulses the wlpers are actuated through a complete revolution -and returnedto the initial position. 'I'he normal contact on C'-I and each successive tenth contact on 'banks C'-I and C'-2 may thenbe con- Vnected together and in circuit with-relay I4 for D, and thence'through the wiper and motor magnet IB- of the switch =D to the positive bus. The intermediate lcontactson bank D--S being con` nected directly to the negative bus, switch D will then be actuated to its( fifth off-normal position where it will again vawait deenergization of relay I5, this relay having been energized through the intermediate contacts on bank D-4 and having completed vitsholding circuit through the contacts of relay I4. Upon the next step of adding switch C' relay I4 will be deenergized but relay I5 will not operate for the reason that its holding circuit is'maintained through bank C'-3. Thus relay t5 responds onlywhen relay I 4 becomes energized. After another ten steps of adding switch C relay vI5 is again deenergized and switch D is stepped through another five operations.

Since the motor magnet I6 advances the wipers of the switch D five steps in response to each received impulse, it will beseen that in response to 10 received impulses the wipers will rotate one Accordingly the wiper of bank D-I of switch D is arranged oncein each revolution to supply an impulse to the next serelay Il is Qpez'ajged once fgr every other opera-IECOI SW'Ch E in the Cascade arrangement.

` end of totalization, relays 29. and 56 are provided,

this purpose the twenty-fourth off-normal contact of bank D|, upontwhich the wiper rests only momentarily, is. connected to the rst and each succeeding fth contact of bank E-l. This selector switch likewise advances five steps for' each received impulse, and its" bank E-l is arranged once in each revolution to supply an impulse to the motor magnet of the next selector tch not shown.

Indicating dials 26, 21 having cooperating pointers mounted upon the shafts of. the selector switches E and D may 'be provided, each dial corresponding to one digit of the total which is to be indicated, that is, the -dial 21 may represent represented by operation of contacts I, 2, 3, 4,

5. 6, etc. will be indicated inV even hundreds and thousands respectively by means of the dials 21, 26 and their cooperating pointers.

In order to restoreswitches A', B', C', D and E to their normal positions, as for example, at the the relay 53 being normally energized and relay 20 normallyl deenergized'. These relays are controlled by means of a key 30, which is normally contacts of the bank A'2 of adding switch A" with the exception of the normal contact are connected together and through one pair or contacts on -relay 23`to the negative side of the batl tery. The wiper of this bank of contacts-is con-v nected tothe stationary contact which cooperates with the amature of the motor magnet 1, and

- thence through the motor magnet to the positive side of the battery. Thus it will be seen that when the'contacts on relay 23 are' closed a buzzer circuit including this bank'- of contacts and the motor magnet of relay ,1' is completed, by means same manner. Adding switch C' is similarly pro. 'vided with banks of contacts C'I and C'-5. All of the @tacts 'oi these banksV with the exception of the normal contact of bank C'-5 are connected together and operate in the same manner to restore the switch to its normal position.

As has already been stated the wipers on these banks extend in opposite directions. vFor the same are provided upon vthe switches D and Ea respectively. At the same time the impulse transmit- A 26, having pointers for indicating m even mow sandsthe total indicated by each oi.' the different ting circuits extending through the motor magnets of the diiierent switches, except those oi'- the collecting devices A, B and C, are interrupted by f relay I6 permitting these motor magnets tol be energized only through. the associated resetting banks whichare provided for the purpose.

Let us assume that in. a particolar installation' there are employed a plurality of systems such as l that shown in Fig. 1 each'of which totalizes the values represented by the sales oi' tickets, for example, with respect to a particular feature of an` exhibition or. the total power indicated by the diiierent meters of a power distribution system,4

motor magnet 36 of adding switch F' which is similar. to switch C'. This collecting device F is controlled by means oi'- relays 33, 3l each of which is controlled from one of the systems corresponding to the system shown in Fig. 1. For example, relay 33 is connected through conductor 35to the contacts on relay I4 such that this relay is de'- energized simultaneously with relay l5, and relay 34 is connected through conductor 34' .to a similar point on another system.

to rotate through a complete revolution and to transmit an impulse through the inner left-hand contacts of relay 33, rst oil-normal contact and wiper. ofthe bank F--2, conductor 3|, contacts 3|' on relay 56, conductor'32 and motor magnet 36 of the adding switch F'.V 'I'hus im'pulses received by the motor magnet 38 of the adding switch F' represent values of 100. Switch F' is connected in the same manner in which switch C is connected and controls 'relays Il' and I5'- which in turn supply impulses representing values of 1000. to the switch G in the same mannerin which relays I4 and l5 supply impulses repre' senting values of -100 to switch D. Switch VG which is similar to switch D is connected in the same manner in which switch D is connected;`

'that is, the wiper of the bank G-l is connected A corresponding relay will be providedfor each system. Deen- -ergization of relay 33 causes collecting device F through conductor 31 andcontacts 31 on'relay '56 to the positive battery; the contacts of banks spondingcontacts on G-I areconnected directly to negative battery, thus it will be seen that the impulses which are supplied to theswitch G represent values of 1000, and that in responseV to each of these impulses this switch is actuated' through ve steps and in response to10 such -impulses the switch completes a revolution and supplies an impulse through the wiper of bank G-I to the next switch H in the cascade connection.

'I'hese switches, and as many others as may be desired,` are similarly provided with dials 21' and systems.

' In case it is desired to produce the indication of total indicated by the system in Fig. 1 at a plu'- rality of different points, thismay bev accomplished by providing relay I5 with one or4 more additional left-hand contacts 4I and causing each -of these contacts to control additionalcascade, v vconnected switches corresponding to switches C',

The indication may be provided at these diierent points by means of Iamps,'as shown in Fig. 3.

In connection with switches D, E anidG it will be` -impulse. It will be seen that in this way sumcient mechanical displacement is provided to permit easy reading of the dials. Where the total is to be indicated electrically as by means of lamps, for example, this is not necessary, and the nrst indicating selector switch may-.be wired as shown at D' in Fig. 3 and controlled. by relay I5 of Fig. 1. That is the motor magnet 42 is'connected in a circuit which extends from positive battery through the motor magnet 42, normally closed contacts on relay 56 (which are represented at 56 in Fig. 3), contacts on relay I5 (which are 'represented at 4I in Figs. 1 and 3) .to the negative side ofthe battery. Thus upon each deenergization of relay I5 the motor magnet 42 of the switch D' is energized through this circuit. When relay I5 is again energized'by bank D-4 of switch D, motor magnet 42 of switch D' is deenerglzed and switch D' is advanced one contact position. Thus switch D' is advanced one step for each received Since the bank D'-3 has 25 contacts' impulse. ve of these contacts are connected directly to the negative bus. The wiper of this bank is connected to the stationary contact cooperating with the armature of the motor magnet so that the switch is actuated over these ve contacts by buzzer action and is returned to the initial position in response to twenty received impulses.. Preferably these contacts are so chosen, as indi- 4cated in Fig. 3, as to separate the remaining contacts into two groups of ten cntacts each. 'I'hese contacts are connected through'v contacts onresetting relay 29 (which are indicated at 29 in Fig. 3) to the negative battery. .Thus this bank is utilized as the resetting bank for the switch D'.

The bank D-2 controls the indicating lamps corresponding to the hundreds digits of the total.

Thus when the switch is in its initial position the lamp corresponding to zero is'lighted. vWhen fit is in position I the lamp corresponding to 10 is lighted, and so on, for the position of the other integers. Bank D\I serves to supply an impulse to the next selector switch in the cascade connection in responseto each 10 received im pulses, which switch, in turn, controls the lamps means whereby theaccurate total may be indicated rather than the total as represented by even hundreds or thousands.

AI, B'-I vand C-I, and C"-2 in the manner shown in Fig. 4. The wiper of each of thse banks is connected to negative potential and each of these contacts is connected through a lamp on the indicating panel 54 to positive potential, the lamps serving to indicate the number of impulses which has caused the wiper to be actuated This may be ef- `fected by wiring the unused contacts on banks the lamps indicating values 10, 20, 30-90, colitacts on bank A'-I control lamps indicating values of 2, 4, 6, and 8 and alternate contacts'on the bank B' being connected to a single lamp indicating the value 5. Thus the total value indicated by these lamps corresponds to the value represented by impulses which are stored in the equipment at any particular. time, and which is not included ih the total as indicated by the selectors D and E. 'Ihe same result of course may be' had by means of dials mounted upon these switches. Similarly the accurate grand total may also be had by also wiring the banks F'I F-2 to indicating lamps in the manner shown in connection with banks C'I 'and C-2.

For out of door purposes or for purposes of large gathering places. it may be desirable to indicate each of the digits by means of. a grou'p 0f lamps', as is lshown in Fig. 6, for example,

Where each of the numbers represented in rows I, 2, 3 to II) correspond to the total indicated by a system such asthat shown in Fig. l, and the total which is indicated at the bottom of the tlgure corresponds to the grand total which is indicated by the equipment shown in Fig. 2. It will be seen that' each digit of each of these quantities is indicated by a plurality of lamps; For the purpose `of controlling the lamps comprising any particular digit the means represented in Fig. 5 may be employed. This means comprises a selector switch I having banks I-I, 1 2, I-3 and I-4 plus one additional bank not shown, which may be wired in the manner indicated in connection with bank D3 of Fig. 3, for example, such that upon each impulse oi the first nine impulses Iii' received, the switch advances one step. Upon receipt of the tenth impulse the switch advances over two contacts and stops upon the next. contact which corresponds to the zero position. Upon receiving each of the next nine impulses it advances one step and upon receiving the tenth impulse advances three steps to the position shown in the drawings.

Associated with this switch are a plurality of relays 44, 45, 46, 41, 48,49, 5U and 5I. I'he relay .44 is-controlled by the wiper of the bank I-4 and the remaining relays are controlled by the wiper of the bank I-S through obvious circuits which may be readilyy traced from the drawings. When these relays areenergized their armatures are actuated to the left, and whe hey are deenergized their armatures are actua The position of the selector switch in which the respective relays are energized is indicated by the following table Integer indicated and switch position Relay Energized 0 44 5l 1 None 2 44 3 44 45 4 46 5 44 47 6 44 48 7 44 49 R 44 9 v 44 50 The lamps L comprising each digit are arranged in ve coliunns of six each and are controlled through relays 44 to 5I and thebanks I-'I and I-2 of the selector switch. One terminal of all to the right.`

the lamps is connected permanently to the lower conductor of the lighting circuit 52, and the other terminal 'of each oi!A the lamps is connected through contacts ofthe respective controlling devices, either onel or more of relays 4 4 to 5| or one of the wipers of the banks I-l and I- -2 to the. opposite side of the lightingcircuit.y

Bearing in mind which of the relays are energized and the position of the selectorswitch, the circuit of each of the lamps which are lighted when any particular integer is to be" indicated may be very readily traced. Thus, for example, if zero is to be indicated the switch will be in the zero position which is that shown inv theA drawings and relays 44 and 5l will be energized. The lamps which should be lighted may be determined from Fig. 6. A circuit is completed for lamps lig-1, L-I3 and L-I2 through the left-hand contact and armature of relay 44. Lamp L-l 9 is lighted in all digits andtherefore is permanently connected across the circuit 52. L-26 islighted through the right-hand Yarmatures of eachof relays 48, v41 and 45 in their right-hand position, and armature of relay 4,4 in its lefthand position.

' Lamp L-'21 is lighted through the left-hand contact of relay 5I in its lefthand position, lefthand contact of relay 46 in its right-hand posivand normal contact and wiper of bank I-.2.'

Lamp L-24 is lighted through right-hand armature of relays 50 and 49 in their right-hand posi- .tion. Lamp L-.IB is lighted through left-hand armature offrelay 49 Iin'its Iright-hand. :position .and armature of relay 44 in its lei '-hand posithe arma- Y tion.v Lamp L-5 is lighted'throug ture of' relay 50 in its right-hand position -and normal contact and wiper of bank Ij--. Lamp L44 is lighted thrugh the middle A.contact oi.' relay 50 in its right-hand position, left-hand armature of relay 41' in its right-hand position, lefthand armature of relay 45 in its right-hand posi- Y tion and normal c ontact and wiper 'of bank `I2.

Lamp L-3 iis lightedthrough the right-hand armature oi! relay 5I in its left-hand position, and lamp L-2 is lighted through the middle armature of relay 49 in its right-hand position, right- .hand' armatures of relay -41 in its right-'hand position and the right-hand armature of relay 45 in its right-hand position and amature of relay\ 44 in its left hand position..

When the switch is advanced to its 4ilrst off normal position relays 44 and 5| are -deenergized and all ofthe lamps, with the exceptiomof lamp L--l9 which is permanently lighted, andi- 24, are extinguished. In this position none of the relays is energized., Lamp L-Zli is lighted through the wiper of the bank I-|.' Lamp L2! is lighted through the right-hand contact of relay 5 I Lamp L--22 is lighted through the right-hand contact of relay 44. Lamp L--23 is lighted through the wiperfof bank r-z andrau is lighted through thev relays 5U andA 49. Similarly.

the circuits for all oi the lamps for each of the digitsmay be readily-traced, the reader determinving from Fig. 6 the lamps which are lighted and bearing in mind the position of the relays and that of the switch. While the system shown in "Fig. 5 hasjbeen described as controlled by relay I5 it will, of course, be understood that this will -depend uponvthe lowest. digit to be indicated by `the systm.- Ir the hundreds digit 1ste bemalcated the system will'be connected to receive impulsesl representing a value of one hundred -and similarly for the other While we have shown a particularembodiment of our invention it will beunderstood byth'ose. skilled in the art that many Vchanges and modications, both in the circuit arrangement and'i'n the instrumentalities employed, 4may be made without departing from our invention -an'd we therefore aimin the appended claims to cover all such changes the true spirit and scope of our invention.
