1 Claim.

This case relates to card-controlled accounting machines.

The controlling record cards have columns of index points perforated according'to a selected 5 code to represent desired items. Reading the card perforations are analyzing means for each column and controlled by the analyzing means according to their readings of the perforations are adding and printing mechanisms. The add- 10 ing and printing mechanisms include several banks of elements and each bank is usually connected to the analyzing means of certain card columns to be controlled by the data in the latter columns of successively fed cards. Thus, num- 15 bering the card columns 1 to 45, columns 1 to 3 of successive cards may control one bank of printing or adding elements and columns 4 to 6 control another, separate bank of printing or adding elements.

20 It is desired in the present case to depart from above practice by providing means to shift the v control, in predetermined sequence, of a bank of printing or adding elements from one group of card columns to another oi. successive cards.

25 Thus, columns 1 and 2 of one card may control 'a bank #4 of elements and columns 3 and 4 of the next card control the same bank of elements. This is the general object of the present invention.

30 The object is further to shift the control of several banks of elements in predetermined sequence, from different groups of card columns. Thus in above example, where the first card has columns 1 and 2 controlling bank #4, columns 35 3 and 4 may control bank #5 and the second card which controls bank #4 by columns 3 and 4 may have its columns 1 and 2 control .bank #5. This alternation in control of the two banks may continue through the run of cards.

It is also proposed to print a list of totals taken in predetermined sequence from different columns of successive cards. Thus printing bank #1 may print the addition of two items, one taken from columns 1 and 2 of one card and the other item 4 taken from columns 3 and 4 of the next card.

' Ancillary to above object is the control of the printing bank first from one accumulator bank and then from another.

The latter object also includes the sequential zeroizing of the several banks of accumulators. Other objects will appear in the further parts of the specification and from the drawings, in

which 55 Fig. 1a is a portion of the circuit diagram,

Fig. 1b is another portion of the circuit diagram, and

Fig. 2 is a timing chart.

For purposes of the disclosure, the record cards will be considered as perforated according to the 5 Hollerith system in which each card column has perforation receiving positions 9, 8, 1,--0, H reading upwardly from the bottom of the card and in which asingle perforation in a column is used to represent a value corresponding toits position in the column. Assume that items A and B are to be-added and their total printed. Assume further that items A are in columns 7 and 8, which may be referred to collectively as card field A of the cards and items B are in 001- umns 9 and 10, which may be referred to collectively as field B of the cards. Each of the series of cards except the first and last has both these items but the first card is bare of item A while the last card is bare of item B. Each card but the first also has a card number, say in columns 4 and 5. These card numbers are progressive, that is, if the second card is number 51, the third card is number 58, the fourth 58, and so on. These card numbers are used to control total taking and accumulator resetting cycles.

The invention has for purposes of the disclosure been applied to the machine described and shown in Patent No. 1,976,617.

After placing the series of cards in the machine, the operator depresses reset key R to close reset key contacts R establishing the following circuit (see Fig. 1a). I

Circuit A.--From line 20, through closed cam contacts P3, relay 2|, line 22, key contacts RF, closed relay contacts 23a, line 24, closed cam contacts L2, and to line 25.

Circuit A energizes'relay 2| to close contacts 21a, thereby shunting key contacts R out of above circuit, to maintain relay 2| energized after 40 following circuit (Fig. 1a).

Circuit C.From line 20, through reset motor RM, relay 28, line 30, contacts 2111, line 3|, and to line 25.

Circuit C energizes motor RM.

At thistime then, motor RM will be set in the reset mechanism to the motor RM for a single total print and reset cycle. During this print 'and reset cycle, cam contacts P1 and P8 will 7 close'momentarily, forming the following circuit (Fig. 1a.) 1

Circuit D.'From line 20, through cam contacts P1, P8, magnets 32, 33,- line 34, control magnet 35. line 38, closed cam contacts LIO, L9, lines 31, 38, and to line 25. V

Circuit D energizes magnet 32 to close contacts 32a thus. shunting out contacts P1 and P8 to maintain circuit D after the latter contacts open.

'Iheoperator now depresses the start key to close contacts ST. Since magnet 35 has been energized by circuit D, contacts 35a are now closed and with closing of contacts ST- the following circuit is established (Fig. 1a.)

Circuit E.From line 25, through contacts 35a, stop key contacts SP, start key contacts ST, magnet 23, contacts 39a, tabulating clutch magnet 39, contacts PI, and to line 20.

Circuit E energizes magnet 39 to open contacts 39a, thus causing above circuit to be completed througha by-pas's path E--l including lines 40,

magnet 4|, and line 49'. As a result magnet 4| is energized and closes contacts 4la to form the tabulating motor circuit as follows (Fig. 1a.)

Circuit F.From line 20, through motor TM, contacts Ma, and'to line 25.

Tabulating clutch magnet 39 being energized at this time due to circuit E, the motor TM is effective upon completion of circuit F to drive the various tabulating mechanisms.

Circuit E, when established, energized magnet 23 to close contacts 231) to by-pass start key contacts ST through a path E2 extending from line 25 through cam contacts L2, line 24, and contacts 23b. Towards the end of the cycle, cam contacts L2 break and path E2 opens. Now with start key contacts also open, " magnets 23, 39, and 4|. are deenergized. Contacts 4| open and the tabulating motor TM stops.

During this first tabulating cycle, cam contacts L9 and LIB open but circuit D ismaintained through a by-pass path including contacts LCLa .and UCLa.

Near the end of the first cycle, after cam contacts L2 open, the leading end of the first card engages the upper analyzing brushes UB and upper card lever 42'. The latter engagement closes upper card lever contacts 42 which establishes the following circuit (Fig. 1a)

Circuit G.From line 25, through contacts 42', relays 'UCL, and to line 20.

Contacts UCLa open as a result of circuit G but by this time cam contacts L9 and LID have re-closed to maintain circuit D operative.

At the end of the first tabulating cycle, relays UCL are energized and control magnet 35 is still energized.

The operator how -again depresses the start key to manually initiate a second tabulating cycle. Circuits E and F are again established and the first card is fed to the lower analyzing brushes LB while the second card is fed to the upper analyzing brushes UB.

During the second cycle, cam contacts L9 and Llll again open but at this time, relay UCL being energized contacts UCLa are opened so that .circuit D is broken, resulting in deenergizing magnet 35 to open contacts 35a and permit contacts 35b to close. Later in the cycle, cam contacts L2 open to break circuit path E2. With contacts 35a open, neither. circuit E or E l lever contacts '43, line 44, relays LCL, and to line 20. Y

After magnet 35 is 'deenergized during the sec-- ond cycle, permitting contacts 35b to close, cam

. contacts L3 close to establish the following circult (Fig. 1a). 1

Circuit J.-From line 25, through contacts 35b,

switch 45, contacts L3, magnet 2|, cam contacts P3, and to line 20.

Energization of magnet 2| closes contacts 2l a to hold circuit J after contacts L3 open. After the latter contacts open, and at the very end of the tabulating cycle, cam contacts L4 close and reset clutch magnet circuit B is reestablished, in turnre-forming reset motor circuit C. The machine now goes through a second reset cycle during which contacts P1 and P8 againclose to reestablish circuit D through magnet 35.

At the end of this reset cycle, cam contacts P2 close and establish a circuit E-3 from line 25, through contacts 35a, contacts SP, contacts LCLb, contacts P2, switch 46, and as before in. circuit E through magnets 23 and 39. Energize.- tion of magnet 39 initiates the third tabulating cycle.

During the first of above described tabuiating cycles, the first card will have been advanced to theupper analyzer brushes CB and will just have closed upper'card lever contacts 42 to form circuit G,which energizes relays UCL.

The description thus far has treated of known matter. The new matter willnow be explained.

During the second tabulating cycle, as the first card passes under brushes UB, a circuit G remains in'force and relays UCL remain energized. At the H point (see Fig. 2) of this second cycle, cam contacts L48 close and the following circuit is established (Fig. 1a).

Circuit K .From line 25, through contacts UCLd, relay 49, cam contacts L48, closed relay- Concurrently with making of circuit El,

parallel circuit Kl are closed through magnets 52, 53, and 54 and these circuits also remain in force during saiddata analyzing period of the third cycle.

Magnet54, when energized, shifts a multiple number of parallel contact blades 54 to open contacts 54a and to close contacts 54b (see Fig. 1b).

Magnet 52, when energized, opens multiple contacts 52a (Fig. 1b).

Magnet 53 upon energization shifts blades 53' to open contacts 53a-and to close contacts 53b (Fig. 1b).

Thus, during the third cycle, from 9 through 0, contacts 542; and 53b are closed and contacts 52a, 53a, and 54a are open. During the third cycle, the first card runs through the lower brushes LB which sense the perforations in index point positions 9 to 0 of the card to read off the data represented by the perforations. The first card of the series has only the item B punched therein, as previously explained. When the brushes LB scanning card columns 9 and 10 bearing data B sense a perforation, an adding circuit is formed as follows:

Circuit L.--From line 25, through lower card lever contacts 43 and circuit breakers 55 (Fig. 1a), common contact member 56 of the lower analyzer-continue with Fig,'1bbrush LB engaging the common member 56 through the perforation in the card, plug socket 51, plug wire 58, plug socket 59, contacts 545, plug socket 60,

line 6i, plug socket 62, adding control magnet 53 of accumulator bank #4, and to line 29.

Magnets 63 when energized by circuits L cause entry of item B into accumulator #4.

At the 9 point (see Fig. 2) of the third cycle, cam contacts L62 (Fig. in) make and a circuit is formed as follows (Fig. 1a).

Circuit M.From line 25, through contacts LCLctor UCLd-relay 50, contacts L52, relay contacts 49a, cam contacts LI5, and to line 20.

Energization of relay closes contacts 50b to form a by-pass path M extending from contacts 59b, through cam contacts L63, and to line 29.

Relay 50 also opens contacts 50a of circuit K.

At the li point of the third tabulating cycle (after contacts 50a have opened), cam contacts Ll5 open and the circuits through magnets 49, 52, 53, and 54 open. Now when contacts L48 close at the H point, circuit K cannot be completed again during the latter part of the third cycle because relay 50 has already opened contacts 50a. As a result, after the analyzing period 9 to 0 of the third cycle, magnets 49, 52, 53, and 54 are denergized.

At the 12 point of the third cycle, cam contacts L63 open to deenergize magnet 50, which permits contacts 59a to make but since by then contacts L48 have opened, circuit K. is still unable to form.

During the third cycle, the second card was passing through the upper analyzer brushes UB. This second card contains perforations in columns 4 and 5 denoting a card number. This card number is used to effect minor control operations. As the first card does not have a card number, there will be no agreement of minor control perforations during the third cycle and consequently at the end of this cycle, control magnet 35 will be deenergized to cause the tabulating mechanism to stop.

The minor group control is effected as follows (see Fig. 1a) The upper brushes UB reading the card number. columns 4 and 5 have their plug sockets 64 connected by plug wires to plug sockets of control relays each having a pick up coil 66a and a holding coil 66b. Brushes LB reading card columns 4 and 5 have their plug sockets 51 connected by plug wires to plug sockets 61 of the same control relays.

If the perforations in the .minor control columns of the upper and lower cards agree, a circult will be formed through each perforation from line 25, through lower card lever contacts 43, circuit breakers 55, common 56 of the lower analyzer, brush LB sensing the control perfora- - contacts 69 and 10.

tion, socket 51, wire to socket 61, pick-up winding 66a, socket 65, wire to socket 64, upper brush UB. common 68, cam contacts LII (closed during analyzing periods) and to line 20.

Energization of winding 66 results in closing When contacts Ill close, a circuit is formed. from line 20, through cam contacts LI 2 (closed during the analyzing period),

gontacts 10, holding windings 85b and to line tacts L9 and LN open. At this time, if the minor control data had not changed, holding windings 56b would be energized and a by-pass path Di around contacts L9, LliLwould be formed from the lower blade of contacts Llil,

serially through the two lowest pairs of closed contacts 59, plug wire Ii, contacts UCLe, to lines 38 and 25.

When circuit D-.i is thus made, magnet 35 stays energized and contacts 35a remain closed. Consequently, when cam contacts L2 open later in the cycle, circuit path E2 opens but with contacts 35a closed and relays UCL energized, a by-pass circuit E--3 around contacts L2'is formed as follows: From line 25. through contacts 35a, contacts SP, contacts 23c,'contacts UCLb, line 24, contacts 23b, magnet 23, line 40, magnets 4| and 39 contacts PI and to line 29.

As in the present case, the first and second cards do not have agreeing control perforations (the card numbers), their concurrent analysis by brushes LB and U3 during the third cycle does not cause the windings 56a and b to be energized so that when, cam contacts L9 and LI 0 open, bypass path D- I is not made and magnet 35 is deenergized. Hence, when contacts L2 open to break circuit path E2, circuit path 13-3 is also open and consequently magnets 39 and 4| are deenergized causing tabuiating motor circuit F to open and the tabulating mechanism to stop a. the end of the third cycle.v

The deenergization of magnet 35 causes a reset cycle to automatically follow the end of the third tabulating cycle in the same manner as described following the second tabulating cycle. At the end of the third cycle, accumulator #4 has had "entered therein item B taken from the first card of the series. Also at the end of the third cycle,- magnets 52, 53, and 54 are deenergized and'contacts 54a, 53a, and 52a are closed. Accumulator #5 is at zero at this time.

When circuit C is closed to operate the resetmagnet 29 is energized and closes contacts 29a.

' ting motor, following the third tabulating cycle,

Consequently, the following circuit is formed a through reset magnet 15-5 of accumulator #5 (see Fig. 1b).

Circuit N5.-From line 25, through contacts 29a, magnet 'I5--5, plug socket I6, plug wire 11,

the bottom pair of closed contacts 54a, plug sockets 59', plug wire 18, plug socket i9, and to line Thus, during the total print and resetting cycle following the tabulating cycle, resetting magnet IS-50f accumulator #5 will be energized to cause resetting of the latter accumulator in the manner disclosed in aforementioned Patent No. 1,976,617.

Cam contacts P6 close at the beginning of the total print and resetting cycle to cause the following 'circuit to be made during said cycle (Fig. 1

Circuit 0-5.-Line 28, cam contacts P6, plug connection 8|, top pair of contacts 54a, plug wire 82, magnet 83-5 and to line 25.

Energization of magnet 83-5 closes contacts 83b-5 to establish the printing control circuits through the bank of printing control magnets 84-5. The printing control circuit is as follows:

Circuit P-5.-From line 25, through circuit breaker contacts 85, common segment 86 of an impulse emitter E (one for all the printing banks), brush '8'! contacting the segment, arm 88, brush 89, commutator element 90, wire 9|, a contact spot 92 of the read-out commutator 93-5, brush connection 94 engaging the read-out spot 92, common conductor 95, contacts 83b-5, line 96, print magnet 84-5, and to line 20.

Since there has been no entry of items yet in accumulator #5 by the end of the third tabulating cycle, this accumulator and its readout commutator will stand at 0, and circuit P-5 will not form since, as indicated in Fig. 1b, the 0 spots of the readout commutators and of the. emitter E are not wired. Consequently, the type bars of accumulator #5 will move to their uppermost position and no printing will be effected since the'hammers will strike .a dummy block in this position of the type bars, as is well known in the art.

During the printing and reset cycle just described, contacts 54b are open. As a result, circuits 0-4 and N-4 do not form. Circuit 0-4 is similar to circuit 0-5 except that the circuit goes through top contacts 54b and through magnet 83-4 of accumulator #4.

Circuit N-4 is similar to circuit N-5 except that the circuit goes through the lowermost pair .of contacts 54b and through resetting magnet item B of the second card in accumulator #5.

15-4. Since resetting magnet 15-4 is not now energized, accumulator #4 retains its entry of item B. Also since magnet 83-4 is not energized, contacts 83b-4 of printing bank #4 are not closed and circuits cannot form through printing magn'ets 84-4.

Following the latter printing and resetting cycle, magnet 35 is again energized and in'the same manner as after the second printing and resetting cycle, a fourth tabulating cycle is automatically initiated.- During this fourth tabulating cycle, the second card goes through the lower analyzer brushes LB and the third card goes through the upper analyzer brushes UB.

As previously explained, at the H point of the third cycle, cam contacts Ll5 opened to break,

the circuits through magnets 49, 52 53, and 54. At the 12 point of the third cycle, cam contacts L63 broke to open the holding circuit M-l through magnet 50. Thus, at the end of the third tabulating cycle, the magnets 49, 52, 53,

,54, and 50 are all deenergized.

During the data analyzing period-9 through O-of the fourth cycle, contacts. 54a are closed. Consequently as the second card goes through the lower analyzer, adding circuit L controlled by the columns 9 and'10 bearing item B, will extend through upper contacts 54a, plug wires 6| and adding magnets 63. of accumulator #5 to enter Adding circuits L will also be formed under control of columns 7 and 8 of the second card bearing an item A. These circuits L will extend through contacts 54a, plug wires 91, plug sockets 62, and add magnets 83 of accumulator #4, thus adding the item A of the second card to the After the analyzing period 9 through 0 of the After the analyzing period 9 through 0 of the fourth tabulating cycle and at the H point, cam contacts L48. make and circuits K are again formed, resulting in energizing magnets 52, 58, and 54 so that contacts 54a open and contacts 54b close, contacts 53a open and contacts 5817 close, and contacts 52a open.

While the second card is passing, during the fourth tabulating cycle, through lower brushes LB, the third card is going through upper brushes UB. Since the card numbers ofthese cards do not agree, the automatic control will again operate to stop the tabulating mechanism at the end of the fourth tabulating cycle and to automatically initiate a total print and reset cycle.

This time, since the'top pair of contacts 54a are open, circuit 0-5 is not formed, magnet 83-5 is deenergized, contacts 8317-5 open, and contacts 8311-5 closed. Since contacts 8312-5 of accumulator #5 are open, circuits P-5 cannot be made through readout commutators 93 of bank #5. As the top pair of contacts 54b are now closed, circuit 0-4 makes to energize magnet 83-4 which closes its contacts 835-4 and opens contacts 8311-4. Closing of contacts 83b-4 forms a readout circuit under control of readout commutators 93-4 of accumulator #4. The latter readout commutators are now positioned to read out the total of items A and B, respectively taken from the second and first card of the series. The readout circuit of accumulator #4 is as follows (Fig. 15): v

Circuit P-4.-Through emitter E, readout commutators 93-4, contacts 8312-4, contacts 53b (now closed due to energization of magnet 53, while contacts 5311 are open), line 98, printing control magnets 84-5, to line 29.

As a result of energization of magnets 84-5, printing is effected in type bank #5 of the reading taken from readout commutator 93-4 of accumulator bank #4 so that the addition of items A and B taken from the second and first cards respectively is recorded under control of add bank #4 in type bank. #5. I

In the absence of magnet 52 and'the opening of contacts 52a during the formation of the latter circuits P-4, a stray circuit would be formed through contacts 830-5 and 52a through add magnets 63 of bank #5 which would energize the latter. his to prevent this that magnet 52 is energized to open contacts 52a during total printing under control of add bank #4.

After total printing in type 'bank"#5 under control of add bank #4, thelatter bank s zeroized since magnet 15-4 is energized by circuitN-4 which extends through contacts 54b now closed.

.Also since contacts 540. are open, circuit N-5 tacts US open after the 0 point. Hence, analysis of the third card by the lower brushes during this fifth cycle, forms the adding circuits L through contacts 545 to enter the item B into accum ator #4 and item A into accumulator #5.

The l tter already contains the reading of item B taken from the second card so that at the end of the fifth tabulating cycle, accumulator #5 has the total reading of items A and B while accumulator #4 has an entry of item B. Cam contacts Ll5 openafter the 0 point of the fifth tabulating cycle, thus breaking circuit K-l. When contacts L48 make at H of the 5th cycle, contacts 50:: are open so that circuit K cannot make. Hence contacts 54a, 53a, and 52a make and the conditions are now the same as at the end of the third tabulating'cycle. Also at the 12 point of the fifth cycle, contacts L63 open to break holding circuit M of magnet 50.

The third and fourth cards have different card numbers causing automatic initiation of a total printing and resetting cycle following the fifth cycle. This time the conditions are the same as during the total printing and resetting cycle fol lowing the third tabulating cycle, that is total printing is effected in type bank #5 under control of readout commutators 92-5 of the total 01' items A and B respectively entered under con- I entered in accumulator #5. Following the fourth cycle, the total of items A and B in accumulator #4 was printed and accumulator #4 then zeroized. During the fifth tabulating cycle, item A of the third card was entered in accumulator #5 to be added to its reading of item B of the second.

card while item B of the third card was entered in accumulator #5.

Following the fifth cycle, the total of items A and B in accumulator #5 was printed and then accumulator #5 zeroized. 'This alternation goes on to the end of the series ofcards.

It will be noted that entry of item A into accumulator #4 occurs while contacts 54a are closed and that during the same cycle after the item entering period, contacts 54a open and contacts 54b close. As a result of closure of contacts 54b, the total printing cycle which follows is under control of accumulator #4. Similarly, following entry of an item A'into accumulator #5, total printing-"is efiected under control af accumulator #5. Thus, total printing occurs under control of the accumulator into which the item A has last been entered. It is not desired to leave an item B standing on the other accumulator when the cards are exhausted. Accordingly, the last card of the series is not punched with an item B, but only with an item A. Hence the final total printing cycle occurs under control of the accumulator into which item A of the last card has been entered following which the latter accumulator is cleared and since no item B has been entered into the other accumulator, the latter is also at zero position.

It will be noted, also, that during formation of printingcircuits P-5, contacts 53b are open so that a shunt circuit cannot be made through line 93 and contacts 535 through the printing control magnets 84-4 of accumulator #4.

Listing during tabulating cycles is prevented in the manner explained in Patent No. 1,976,617. Briefly, this is done as follows:

During entry of items into the accumulators, contacts 830-4 and 5 are opened to prevent energization of magnetsv 84 of ac'cum ulators #4 and #5 and consequent listing of the entries. To prevent listing, magnets 83-4 and 83-5 are energized during the period of a tabulating cycle in which circuits L may be formed. The circuit 5 for energizing magnets 83 during tabulating cycles is as follows (Fig. 1a).

Circuit Q.-From line 25, through card lever contacts 43, cam contacts P9, normally closed contacts 215, contacts 350 (closed by magnet 35 during tabulating cycles), magnet 26, and to line Magnet 26 energized by above circuit closes contacts 26a to form the following circuit through magnet 83-4 (Fig. 15).

Circuit R-4.-From line 28, through cam contacts Ll4 (closed during data analyzing period 9 through 0) switch 99, contacts 26a, magnet 83-4, and toline 25.

Simultaneously a circuit is formed through magnet 83-5 as follows.

Circuit R-5.-Line 20, through contact's Ll4,

. switch 99, contacts 26a. (closed by magnet 26),

magnet 83-5, and to line 25. I

Thus during tabulating cycles, magnets 83-4 and 83-5 are energized to open contacts 83a-4 and 83al-5 thereby preventing energlzation during the tabulating cycles of the printing magnets 84-4 and 85-5.

As previously explained, at the end of each tabulating cycle, in the present case, the circuit through magnet 35 is broken because of lack of agreement in the group control columns 4 and 5.

Further, magnet 2| is energized by circuits D and D-I during total print and resetting cycles. Still further, cam contacts P9 open at the very beginning of the total print and resetting cycle. Thus, during the total print and reset cycle, circuit Q is open at contacts P9, at contacts 350 because of deenergization of relay 35, and at 2!?) becauseof energization of magnet 2|. Magnet 26 is thus inactive during total printing so that contacts 26a and 26a are open and neither of circuits R-4 or R-5 can be formed. This leaves magnet 83-4, and 5 free to be selectively energized during the total print cycle under control of circuits 0-4 and O-5.

Briefly, the described apparatus functions to alternately enter into different accumulators an item taken from the same card columns of successive cards; to enter into the same accumulator during successive cycles a pair'of items taken in alternation from diiferent columns of successive cards; to total print from a single type bank the total taken in alternation from a pair of accumulators and to zeroize the accumulator from which the total is taken. An example of the utility of the apparatus is in the sale of bales of cotton which are shipped to the purchaser. The

' cotton may absorb moisture during shipment and it is desired to add a certain average moisture weight to the original weight of each bale so that the consignee may not claim an excessive weight of moisture as part of the total weight of the bale at the destination. Thus the card number in card columns 4 and 5 may be. the number of the bale, item A maybe the original weight of 'the bale, and item B the average moisture weight to be added by the consignor to the original weight. l

The first card contains only the moisture weight, item B. The second card contains item A, which is the original weight of the bale, and

also contains items B. Items B are'the same 75 entered in accumulator #4 under-control of the first card. The next. tabulating cycle, item A of the second card will be entered in accumulator #4 while item B of the second card will be entered into accumulator #5. The total of items A and B in accumulator #4 will then be printed by type bank #5 followed by the clearing of accumula-.

the art, and need not be explained herein.) The fifth tabulating cycle enters item A of the third card, representing the original weight of the second bale, into accumulator #5 while item B is again entered into accumulator #4, as during the third cycle. The total print is then effected by type bank #5 under control of adding bank #5. Thus, during the third cycle, item B was entered into accumulator #4, and during the fifth cycle the item B was again entered in the same accumulator. During the fourth cycle, item B was entered into accumulator #5 and during the sixth and so on every other cycle will again be entered into the latter accumulator.

Similarly, item A was entered into accumulator #4 during the fourth cycle and during the sixth will again be entered into accumulator #4 while item A is entered into accumulator #5 during the fifth, seventh, ninth, and so on, cycles. Also, after each entry of item A, the accumulator receiving this entry will control a total printingoperation and will then be cleared. After each tabulating cycle, type bank #5 will print the total of items A and B taken, in alternation,
