This invention relates to accounting devices,
and more particularly to a register for account-- ing machines. 7
It is an object of the present invention to pro- 5 vide a simple and highly efficient high speed register for accounting devices.
In accordance with one embodiment, the invention contemplates the provision of a register for calculating machinery which has a transfer system comprising carry preparatory elements which operate during each input cycle of the register and which in their operation engage carry elements previously locked in position to be engaged thereby in any denominational order 15 of the register from which a carry is necessary.
The register is also equipped with mechanism whereby it may control a recording mechanism to cause it to record a grand total and return to zero or it may control the recording mechanism s to record a progressive sub-total and return to the position where it indicates the number recorded.
A complete understanding of the invention may be had from the following detailed description when considered in conjunction with the accompanying drawings, wherein Figs. 1 and 2 when viewed collectively disclose schematically an electrical tabulating system including a register mechanism forming the subject 30 matter of this invention, together with auxiliary circuits for controlling the register and for listing or printing the total or progressive totals of a plurality of items added in the register;
Fig. 3 is a front elevation of the register mechanism;
Fig. 4 is a vertical section taken along the line l-l of Fig. 3, in the direction of the arrows, and
Figs. 5 and 6 are fragmentary vertical sec- 40 tions taken on the lines 5-5 and 6-6, respectlvely, of Fig. 3 in the direction of the arrows.
Referring now to the drawings, wherein like reference characters designate the same parts throughout the several views, particular reference being had to Figs. 1 and 2, the drawings show a card feeding and sensing mechanism I; a register mechanism 2, controlled by the card sensing portion of the card sensing and feeding mechanism; and a printing mechanism 3 inter- 50 connected with and adapted to be controlled jointly by the register mechanism and the card sensing mechanism.
The mechanical features of the card feeding mechanism and the printing mechanism may be 55 of any known type which may be controlled electrically and which will operate in accordance with certain definite requirements to be outlined hereinafter, and in order to simplify the disclosure, these structures have been shown only schematically whereas the register mechanism to which this invention particularly relates will be shown and described in detail.
Referring now to Figs. 3 to 6, inclusive, the register comprises a base plate 4 upon which are supported 8 vertically extending plates 5, 6, l, 8, 9, H), II, and I2. Between the plates 5 and B, 6 and 1,1 and 8, 8 and 9, 9 and HI, ID and H, and i i and I2 are positioned the register units, for the units (U), tens (T), hundreds (H), thousands (TH), ten thousands (TT), hundred thousands (HT), and millions (M) denominations, respectively. Each of the register units from units (U) to millions (M), inclusive, are similar in construction and the details of construction of only the millions register unit will be described in detail.
The power for driving the moving parts of the entire system. is derived from a motor i 8 (Fig. l) which drives a common drive shaft i9, suitable gearing 20, 2|, and 22 (Figs. 1, 2, and 3) being provided for driving the card feeding and sensing mechanism I, the register mechanism 2 and the printing mechanism 3, respectively. The gearing 2i drives a, stud shaft 23 which is mounted upon a bracket 24 secured to the vertically extending plate i2 (Fig. 3). The bracket 24 also supports an electromagnet 25 having its armature normally latching a driven clutch member 26 out of engagement with a driving clutch member 21. Upon energization of the electromagnet 25 the armature will unlatch the driven clutch member 26, and permit it to be moved by spring pressure into engagement with a driving clutch member 21 secured to the stud shaft 23. The driven and driving clutch members 26 and 21 form a part of a single revolution clutch 28 which, upon momentary energization of the electromagnet 25, will drive a main register shaft 29 through one revolution and at the end of a revolution the driving and driven clutch members 21 and 26, respectively, will be disengaged and the main register shaft 29 will be stopped if the electro magnet 25 has been de-energized since the armature of the electromagnet will cam the clutch member 26 out of engagement with driven clutch member 21.
The main register shaft 29 is mounted in upwardly extending portions of the vertically extending plates 5 to i2, and carries at its right end (Fig. 3) a pinion gear 30 which meshes with an idler 3| rotatably mounted upon the vertically extending plate 5 and in turn meshing with a pinion 32. A register drive shaft 40 extends through and is journaled in all of the vertically extending plates 5 to I2, inclusive, and has fixed thereon the pinion 32 so that upon energization of the electromagnet 25 the single revolution clutch 28 will engage to drive the main register shaft through a single revolution, thereby to drive the shaft 40 through one complete revolution and a portion of another revolution since the gearing arrangement between the pinion gear 30, idler 3 I, and pinion 32 is such that upon a single revolution of the main register shaft 29, the register drive shaft 40 will be driven through one revolution and a portion of a second revolution. The purpose of driving the shaft 40 through more than one revolution will become apparent as the description progresses.
Slidable longitudinally on and rotatable withthe shaft 40, in the millions (M) register unit,- is a driving clutch member 4| provided with a peripherally extending groove 42 into which exmember 4| out of engagement with a driven,
clutch member 50.
The driven clutch member 50 is normally held against rotation with the shaft 40 by a spring pressed center stop 55 (Fig. 4) which carries a roller 56 for. engaging in a center stop cam 5'I, formed integrally with the clutch member 50. However, upon energization of the electromagnet 45, the driving clutch member M will be moved into engagement with the driven clutch member 50 and will drive the clutch member 50.
Secured to and insulated from the clutch member 50 is a contact disk 58 which is comprised of a base of non-conducting material 59 and plates 60 and SI of conducting material shaped as shown in Figs. 5 and 6. The contact disk 58 is divided into 10 sectors and upon being rotated will be stopped by the center stop 55 in a position where a group of brushes 62, 63, and 64 cooperating therewith will all engage the disk at oneof positions to 9 inclusive. The brush 82 will be in engagement with the plate 80and will be electrically interconnected therethrough with the brush 63 at all rotative positions of the disk except its 0 position since the brush 63 contacts with the plate 80 in all rotative positions, and the brush 82 contacts with the plate 80 in'all rotative positions except the 0 position, at which time the brush 82 will be in engagement with the base 59 of non-conducting material. The plates 60 and 8| are electrically interconnected through the base 59 by rivets 85 of conducting material, therefore, the brushes 63 and 64 will be electrically interconnected only at rotative position 9 of the contact disk 58, since the brush 83 engages plate 80 at all times and the brush 84 engages plate 6| when the contact disk is in the 9 position only.
The brushes 82, 83, and 84 are insulated from' each other and are insulated from and mounted upon the vertically extending plate II.
Formed integrally with the driven clutch member 50 is a carry cam 'lI adapted to engage a carry cam roller 12 for actuating a trip latch 73 upon which the carry cam roller is mounted, as the contact disk 58 moves from the 9 position to the 0 position. The trip latch 13 is pivotally mounted on the vertically extending plate II at 14 and has a pair of indentations I and formed in a horizontally extending portion thereof for engagement by a spring pressed center stop 18 so that upon the carry cam II engaging and actuating the carry cam roller I2 the trip latch I3 will remain in its actuated position until positively moved to its normal position as shown in Fig. 4. Cooperating with the trip latch I3 is a contact spring ll which, upon the contact disk 58 moving from the 9 to the 0 position will be actuated through the operation of the cam II on the cam roller I2, and will be moved to the right (Fig. 4) and held in that position by the center stop 18' until positively cammed against the action of the center stop back to its normal position, as shown in Fig. 4. Cooperating with the contact spring I! are a pair of nines preparatory contact springs 19 and 80 which, during each cycle of the rotation of the main register shaft 29, are adapted to be actuated by a lever 8I secured to a shaft 82. The shaft 82 has secured thereto a camlever 83 and is oscillatable in a projection 84 formed on the vertically extending plate I2 and a projection 85 formed on the vertically extending plate 5 by a cam 88 mounted upon the main register shaft 29 which engages and actuates the cam lever 83 with which it cooperates.
The main register shaft 29 also supports a pair of control contact disks 81 and 88 (Fig. 3) similar to the contact disks 58. These contact disks 8! and 88 have cooperating therewith contact springs 89, 90, 9|, 92, 93, and 94, the function of which will become apparent as the description of the circuit progresses.
Referringnow to Figs. land 2, the gearing drives a driving clutch member I05 forming a part of a single revolution clutch I06 similar to the single revolution clutch 28, which operates thereof in a suitable magazine (not shown) and by any of the well known card feeding mechanisms, to a point where the card will be engaged by card feed rollers I I2 driven from the shaft I08. The cards II I are the ordinary perforated cards used in statistical compiling and card controlled computing machines, for illustration;
the mechanism disclosed is adapted to use cards having 45 columns of 10 holes each.
The card, upon engaging the card feed rollers II2, will be advanced to a position where the forward end of it will engage a pluralityof control brushes H3 of which there are provided 45 for sensing the 45 columns in the record card III to determine the location of perforations therein. In each cycle of rotation of the shaft I08 a card III will be selected and will be advanced to a position Where the forward end of the card is between the brushes H3 and a sensing drum H4 with the card in such a position that it will insulate all of the brushes H3. from the sensing drum II4, the hole positions of the card not yet having reached the sensing brushes H3. Each of the brushes H3 is connected to a jack H5 individual thereto. For the sake of simplifying the disclosure only one jack H6 has been shown, but it will be understood that there are 45 jacks H5, each Jack connected to a different one of a series of brushes H3. This group of brushes may thus be interconnected with a group of control relays for controlling the operation of the mechanism in a manner to be described hereinafter.
Directly in alignment with the brushes H3 is a card actuated roller H6 positioned upon one end of a pivoted bell crank lever H1 which, when a card is in position between the brushes and the card actuated roller H6, and the drum H4, will be rocked about its pivot H8 in a clockwise direction to move a pair of contacts H9 and I20 into engagement with a pair ofcooperating contacts I2I and I22, respectively. The contacts H9 and I20 are connected to ground at I23, and upon their actuation, due to a card engaging the card actuated roller H6, ground at I23 will be connected through the contacts H9 and I20 over two paths, one path extending from the contact I2I to a brush I33, and the other path extending to a break contact I34 ofa relay I35. The brush I33 is always in contact with a conducting portion of a contact disk I36, mounted upon the shaft I08. A second brush I31 associated with the contact disk I36 engages a conducting portion thereof at that time during the rotation of the shaft I08, when a card is between the brushes I I3 and the sensing drum I I4. and will interconnect ground at I23 to the sensing drum H4 at all times when a card is between the brushes H3 and the sensing drum H4.
Simultaneously with the encrgization of the electromagnet I01 to trip the clutch I06, ground will be connected through the start key H0 to the windings of a relay I38, the other side of the winding of which is connected to grounded battery at I39, and to a contact I 40 which normally engages a second contact I4I connected in series with a contact I42 normally engaging a contact I43 and connected to the break contact I34 of relay I35. A locking contact 343 connected to the ground side of the winding of the electromagnet I01, upon energization of the electromagnet, will be engaged by a cooperating contact I44 connected to a brush I45. The brush I45 makes contact with a conducting portion of a contact disk I46 mounted on the shaft I08 in normal position, and also during that portion of the revolution of shaft I08 that a card IH is being advanced from the supply of cards into position between the brushes I I3 and the sensing drum H4 to connect ground from I41 through a brush I48 which always engages a conducting portion of the contact disk I46 through the brush I45 and locking contact 343 to the winding of the electromagnet I01. Thus ground will be connected to maintain the electromagnet I01 energized over the just described locking circuit until a card from the supply III has had time to engage the card actuated roller H6 and cause the ground connection at I 23 to be connected to contact I22, at which time the circuit will be maintained from ground at I 23 if the supply iii of cards is not exhausted. When the supply III is exhausted, neither of these circuits will be effective and the circuit maintained over another path to be described hereinafter for one more revolution of the shaft I08.
Connected to the shaft I 08 through gearing I55 is a shaft I56 which in turn through gearing I61 drives a shaft I50, having mounted thereon a pair of cams I59 and I60. Cams I59 and I60 have cooperating therewith contact levers I6I and I62, respectively, which are slidable horizontally on pins I63 and I64, respectively, and which are normally urged in a counterclockwise direction about the pins I63 and I 64 by contractile springs I60 and I66 into engagement with abutments I61 and I60, respectively, on brackets I69 and I10, respectively, which support the pins I63 and I64. The brackets I69 and I10 also support the contacts I40 and MI, and I42 and I43, respectively. The contact levers I6I and I62 also serve as the armaturesof contact lever relays HI and I12.
The contact lever relays Ill and I12 have one side of their winding connected to grounded battery at I13 and I14, respectively, and have the other side of their winding connected through break contacts I15 and I16 of a relay I11 to a brush I18, which makes contact with a conducting portion of contact disk I46, as the contact levers I6I and I62 near the position where they would engage contacts I40 and I43, respectively, to connect ground from I41 to the windings of the contact lever relays HI and I12 to energize them and to. attract the contact levers I6I and I 62 thereby to prevent the disengagement of contact I40 from contact MI, and contact I43 from contact I42, each time the shaft I08 rotates when the relay I11 is not energized.
The arrangement of the cams I59 and I60 is such that they normally move their associated contact levers I6I and I62, respectively, upwardly to disengage contacts I H and I42, respectively, just before a card passes out of a position between the brushes II 3 and the drum H4 to disconnect ground at I23 from the locking circuit of electromagnet I01. However, during the first rotation of the shaft I08 contact lever relays HI and I12 will be operated in time to prevent the breaking of the locking circuit over the hereinafter described. circuit through break contacts I15 and I16 of relay I11, which will not be eneriized during the first cycle of rotation of shaft After driving the shaft H18 through one revolution, due to the operation of the start key H0, the clutch I 00 will remain engaged due to the locking of the circuit for the electromagnet Hi1, and the first card ill drawn from the supply thereof will be advanced by the sensing drum 5 I4 and card feed rollers I into a position between a sensing drum I86 and a plurality of recording brushes I81. There are provided 45 brushes I81, each of which has individual thereto and i connected therewith a jack I88 into which may be plugged any one of a. plurality of electrical connecting cords I89 connected to the register mechanism or electrical connecting cords I90 connected to a control system indicated generally by the numeral I9I.
When the first card advanced from the supply III reaches a position where it will be between the recording brushes I81 and the sensing drum I86, it will engage a card actuated roller I mounted upon a pivoted bell crank lever I96. The card, in engaging the card actuated roller I95, will rock the pivoted bell crank lever I 96 about its pivot I91 to move a pair of contacts I98 and I99 into engagement with cooperating contacts 200 and 20I, respectively. The contacts I98 and I99 are connected to ground at I23 and while a card is between the sensing drum I86 and the recording brushes I81, ground at I23 will be connected to the contacts 200 and 20I', respectively. Contact 20I is connected in series with contact I22 and will serve the same purpose as did contact I22, while contact 200 is connected to a brush 202 always in engagement with a conducting portion of a contact disk 203 mounted upon the shaft I08. Ground will thus be connected from I23 to the contact disk 203 at those times when a card is in positionbetween the recording brushes I81 and the sensing drum I86, and a brush 200 also associated with the contact disk 203 will connect ground to the sensing drum I86 at those times while a card is between the recording brushes I81 and the sensing drum I86 and will also connect ground to make contacts of a plurality of control relays 205, 206, 201, and 208.
A third brush 209 associated with the contact,
disk 203 will make contact with a conducting portion of the contact disk momentarily just after the card II I engages the card actuated roller I95 to connect ground from I23 through contacts I98 and 200, brush 202, contact disk 203, brush 209 to the winding of relay I11, the other side of the winding of which is connected to grounded battery at 2 I0 thereby to energize relay I11 which will lock up over a locking circuit to be described in detail hereinafter. The energization of relay I11 will render contact lever relays Hi and I12 inefiective over the circuit previously described for operating them. Y
Associated with the group of 45 jacks II5 are a plurality of connecting cords 220, of which there may be any desired number, but for the sake of illustration only four connecting cords have been shown. These connecting cords serve to connect any one of the jacks II5 with any desired ones of a plurality of jacks 22I, associated with four control relays 222, 223, 224, and 225.
The control relays 222, 223, 225, and 225 are associated with the control relays 205, 206, 201, and 200, respectively, and when any pair of associated relays are operated simultaneously, as
described hereinafter, the associated relays will hold operated over a locking circuit to brush 200. The control system also includes a pair of grounded jacks 226 and 221, and a plurality of connecting cords 228 which, if connected as indicated in Fig. 1, will set the system up so that when a disagreement occurs in the cards in the control columns associated with relays 201, 208, 224, and 225, a progressive total will be printed and the register .will be returned to register. the amount therein before the printing occurred, while if a disagreement occurs in the columns of the card associated with relays 205, 206, 22I, and 223, a grand total will be printed and the register cleared out.
For control purposes the control relays 205, 206, 222, and 223 are grouped together and upon the simultaneous operation of relays 205 and 222, either preceded by, simultaneously with, or followed by the simultaneous operation of relays 205 and 223, a circuit will becompleted from grounded jack 226 through the right hand armatures of control relays 222 and 205, which will have been locked up, through the right hand armatures of relays 223 and 206 which will also have been locked up, through a jack 229 to the winding ofrelay HI and through contacts I15 and I18 of the relay I11 to the windingof relay I12. The circuit for locking relays 205 and 222 when they are simultaneously operated and for locking relays 228 and 206 when they are.
at brush 200 through the extreme left-hand make contact of relay 205, extreme left-hand make contact of relay 222, which is connected to the locking contacts of both relays 205 and Control relays 201, 222, 208, and 225 operate in exactly the same manner as do control relays 205, 222, 206, and 223 except that relays 201, 208, 224, and 225 will connect ground from grounded jack 221 through right-hand armatures of relays 201 and 220, right-hand armatures of relays 225, 208, through a jack 230 connected to winding of relay I12 and thence progressively through contacts I16 and I15 of relay I11 to the winding of relay I1I.
Each time the cards passing the brushes H3 and I81 operate all of the control relays, the contact lever relays HI and I12 will be operated and the cards will continue to feed past the brushes and in passing the brushes I81, seven of which are connected through the connecting cords I 89 to the register, the quantities reprewill be driven through one revolution, synchronously with the rotation of shaft I08. As the perforations in the record card passing between the recording brushes I81 and the sensing drum I88 encounter the brushes, ground will be connected from the brushes through the connecting cords I89 to one side of the winding of the electromagnets '25, the other side of the winding of which is connected to grounded battery at 200 (Fig. 2), and the register will have entered into it the number punched in the card.
Momentary energization of the electromagnets due to the brushes I81 encountering perforations in the record card passing under them will cause the clutch member II to engage the clutch member 50 momentarily, and in order to maintain the driving connection for the disk 58 associated with one of the brushes I81, a locking circuit to maintain the clutch electromagnet 45 energized must be supplied. Each of the electromagnets 85 from units (U) to millions (M), inclusive, has individual thereto a holding relay 2M which is connected in parallel therewith through the break contacts of a relay connected in parallel to grounded battery at 243 and upon energization of any one of the holding relays simultaneously with the energization of the electromagnet 45 associated therewith, the holding relays will lock up .to ground at 244 through brushes 92 and 8| and the breakcontacts of a relay 245'and a progressive total relay 248.
From the foregoing it will be apparent that a card, in passing between the brushes I81 and the drum I86, will cause to be registered on the disks 58 amounts corresponding to the amount indicated by perforations on the record card; that is, the electromagnets 45 will be energized at predetermined times, depending upon the position of perforations in the columns of the record card associated with brushes I81 which have been interconnected with the electromagnets 45, and the circuit for maintaining the electromagnets 45 energized will be maintained until the ground connection at 244 is removed from the holding relay due to the brush 9| engaging a nonconducting portion of the control contact disk 81.
The first card of any series of cards in passing the brushes I81 will in the hereinbefore described manner put into the register the number perforated in the area of the card associated with the register mechanism and no carry operation will be necessary unless the registers have had previously entered therein a number which, upon the addition thereto of the number perforated in the first card of the series, would cause one or more of the disks 58 to pass from the position where they indicated 9 to the position where they indicated 0.
Whenever a carry operation is necessary, the contact disk, in moving from its 9 position to its 0 position, will actuate the trip latch 13 to move the contact spring I1 into a position where it will thereafter be engaged by the contact spring '80 and the spring 11 will be latched in its actuated position by the center stop I8.
After the input cycle of the register has been completed, the nines preparatory contacts 19 and will be moved toward the contacts 11 and will engage any of the contacts 11 which have been moved out of normal position due to their associated contact disks 58 having passed from the 9 to the 0 position, and while all three of the springs are in engagement a carry pulse of proper duration to add 1 in any register, whose reading should be increased. by 1 due to a carry from the next lower dial, will be transmitted to the electromagnets 45. This carry pulse is controlled by the contact disk 81 whichhas a conducting portion thereon associated with the brush of a. size sufiicient to maintain ground at 244 connectedthrough the break contact of relays 245 and 246 to the contacts 11 long enough to move the register disks 58 one position if the contacts 11 are connected through the contacts 80 and 19 to the electromagnet 45. These circuit connections are sufficient to make an ordinary carry. However, when a carry'upon a carry is necessary; that is, when, for example, the units contact disk 58 passes through the 9 position to indicate a numher other than 9 due to the addition of two numbers whose sum is greater than 9, and the tens and hundreds contact disks have been moved to the position where they indicate 9, it will be necessary to raise the value of the number indicated by the tens register 1, and it will also be necessary to raise the numbers registered in the hundreds and thousands registers by 1, although the contact disks in the hundreds and thousands registers have not passed through the 9 position. In order to accomplish this, the contact disk 58 has been provided with a conducting portion which will engage brush 64 when the contact disk is in the 9 position, and the brush 64 associated with the contact disk 58 which is in the 9 position and whose next lower contact disk 58 has passed from 9 to 0 will also receive the carry pulse since the brush I9 associated with the units contact disk is connected not only to the electromagnet 45 of the tens order, but is also connected to the brush 53 in the tens order and the circuit will not only energize the electromagnet 45 in the tens order but will also be sent through the brush 53 in the tens order which always engages a conducting portion of the contact disk 58, and through the disk and brush 64, through contacts 80 and 19 to the winding of the electromagnet 45 in the hundreds' order. The electrical connections running through all of the registers are of exactly the same construction except that when a carry is indicated as necessary in the millions order, and this condition occurs every time there is a problem of subtraction being performed since the complement of any number capable of being handled by the machine must have a 9 in the highest order, the contact 18 associated with the millions order is connected to the electromagnet 45 in' theunits order. Thus, the digit 1, which is usually lost in performing problems of subtraction by the addition of complements of numbers, is automatically transferred to the lowest order dial, where in the machines heretofore known 1 had to be added in order to perform these problems.
As an example of the method of effecting problems of subtraction, let it be assumed that the register has registered therein the number 94872, and it is desired to subtract from this number the number 5871. With this assumed set of circumstances the card which controls the subtraction of 5871 from 94872, the amount stored in the register will be punched in the usual manner, not with the number 5871, but with the complement of 5871 based on nine or 9994128 and diagrammatically the problem will be efiected as follows:
M HT 'r'r TH E T U 0 0 9 4 8 7 2-number stored in register. 9 9 9 4 l 2 8number, representing complement of 5871, to be added to number stored in register.
0-arnount registered before carry pulse is sent through. l-carries from units to tens, tens to hundreds and millions to units.
As long as both corresponding areas of the cards under the brushes H3 and I8! agree, the card feed will continue, and the information represented in those areas of the card which have been associated with the register cause the algebraic sum of the numbers perforated in the cards to be accumulated in the register as described hereinbefore. However, as soon as a card engages the control brushes H3 and does not agree with the card simultaneously passing the brushes I81 in the compared areas of the cards, either the magnet Ill or the magnet H2 will fall to operate since its ground connection through the control relays will be broken, and thus a printing operation will be instituted. With the control relays connected as shown in Fig. 1, a progressive total will be taken and printed when the areas of the cards associated with the relays 201, 208, 224, and 225 disagree tion of the disk 253 at all times except when the I since the circuits described hereinbefore will not be completed to connect ground to the magnet I12, and when the magnet fails to operate, ground -at I23 will be disconnected from the winding of,
' 255 is connected to a brush 256 which always engages a conducting portion of the contact disk253. u
Since thebrush 252 engages a conducting pordisk is in normal position, the ground connection to hold relay I35 operated will be maintained until just before the printer shaft 254 reaches its normal position provided the circuit made at contact 256 associated with the electromagnet I12 is made just after the printer shaft 254 moves out of normal position. The printer shaft 254 will be started through its rotation due to' the energization of an electromagnet 251 which controls a single revolution clutch 258 similar to the single revolution clutches 28 and I66 and which has one side of its winding connected to grounded battery at 259 and has the other side of its winding connected through the break contact of relay I38 which was de-energized simultaneously with the de-energization of electromagnet I61 with which it is connected in parallel, through a make contact of relay I11 which was operated when the first card engaged the-card actuated lever I96 and through brush 89 to ground at 244. The brush 89 makes contact with a conducting portion of the disk 81 at a point such that the register shaft 46 and the printer shaft 254 will, when the circuit conditions are as Just outlined, start the shafts 46 and 254 synchronously.
As the printershaft 254 moves out of normal, a cam 266 mounted thereon will move a cam-lever 26I to the left (Fig. 2) to interconnect a plurality of conductors 262 connected to brushes 64 associated with contact disks 58 in the register, to a plurality of selecting electromagnets 263, forming a part of a printer mechanism 264 which may be of any well known type but which has been shown schematically as the usual Hollerith type of printer which is well known in tabulating art.
Each time the printer shaft 254 rotates, a contact disk 266 which is connected to ground at 255 through a brush 261, which always engages a conducting portion of the disk 266, will connect ground through a brush 268, break contact of a progressive total control relay 269 to one side of the progressive total key 265, and if the keyhas been operated the ground connection from 255 will be completed to the winding of a relay 216, the other side of the winding of which is connected to grounded battery at' 28I to energize the relay 216 unless the progressive total control relay 269 has been operated.
When relay 216 is energized over the just described circuit, it will through its break contact disconnect the winding of relay 242 from the brush 282 associated with contact disk 253 and will simultaneously through its make contact connect ground at 283 to the winding of relay 246 to energize relay 246 since the other side of the winding of relay 246 is connected to grounded battery at ,284. The energization of relay 246 will, through its break contact 285, void the circuit over which a carry pulse is transmitted to the register contact disk 58 so that no carries will be made when the device is operating to print a total, andthe holding circuit for the holding relays 248 will be transferred from a back contact 286 to a front contact 281. When the holding circuit for the holding relays 24I is connected to contact 281 of relay 246, the holding relays 24I will remain locked up over-a circuit to brush 93 associated with contact disk 88 and since the brush 93 is in engagement with a conducting portion of the contact disk 88, from shortly after .the shaft 66 starts to rotate until the shaft 46 completes one revolution, the brush 93 will hold the contact disks 58 in rotation until they have completed one revolution and returned to the position where they will indicate the number preuriously stored in them. I
The just described circuits will be effectlvewhenever a progressive total is printed, since the progressi-ve total control relay 269 will not be operated due to the fact that there are still cards associated with both the brushes H3 and I61, and the area of the cards associated-with relays 265, 266, 222, and 223 agree. If the supply of cards III is exhausted, then the progressive total control relay 269 will be operated from ground at I39 through the contacts 256 associated with the card lever magnet I12, a pair of contacts 288 associated with card lever magnet I1l which will not be energized since, there being no card between the brushes I 81 and drum I86, card actuated contact lever I96 will not be operated and ground at I23 will be disconnected from the contact 266 which is connected to brush 262 and through the disk 263 to brush 264 when cards are in position between the brushes I81, and drum I86. When the relay 269 is operated the ground connection from 255 to brush 268 will be broken at the break,
contact of relay 269 and relays 216 and 246 will not be operated and the circuit to the locking contacts of the holding relays 24I will then be connected through contact 286' of relay 246 to a I break contact of relay 245 and to brush 9| associated with contact disk 81. However, when a grand total is to be taken, due to the failure of the card lever'magnet I1I to operate, either because of the exhausting of the supply of cards or because relays 265, 266, 222, and 223 do not operate due to a disagreement in the areas of the cards associated therewith, the printer shaft 254, at the start of its rotation, will cause contact disk 253 to connect ground at 255 through brush 282 to the winding of relay 245, and through the break contact of de-energized relay 216 to relay 242. The energization of. relay 245 will also disconnect ground at 244 through brushes 92 and 9I position, will be disengaged from the driving shaft 4|) and the register will be clear. During a printing cycle, whether a progressive total or a grand total is to be printed, the contact disks 58 in arriving at the 9 position energize the selecting electromagnet 263 and the printer mechanism 264 associated therewith to cause the number indicated by the position of the contact disk to be printed. Since one side of the winding of the selecting electromagnet 263 is connected to grounded battery, ground must be supplied to the other side thereof to energize the relay, and this ground is supplied to the selecting electromagnet over the conductors 262 and brushes 64 associated with the contact disks 58 and from the brushes 62 which engage a conducting portion of the contact disk 58 at all times except when the contact disk is in normalposition over a plurality of conductors 290 connected to brushes 29I which engage conducting portions of contact disks 266,
Let it be assumed that a supply of cards III' are positioned in the magazine (not shown), a
which cards are perforated with information representing a plurality of transactions in each of a plurality of accounts, the transactions being represented by perforations in corresponding areas of a variable number of cards and the information representing accounts belngperforated in other corresponding areas of the cards. If it is desired to take progressive totals of the information in the various accounts and a grand total of the information in a number of accounts less than the total number of accounts represented by the cards, the progressive total key 265 should first be operated and the control relays interconnected as shown in Fig. 1. With the machine set up in this manner, every time the account changes a progressive total will be taken if the card changes in the area associated with control relays 201, 208, 224, and 225 and a grand total will be taken when a change occurs in the areas of the cards associated with relays 205, 206, 222, and 223 or when the supply of cards is exhausted.
With the machine connected as just described, the operation of the start key IIO will put the machine in operation to operate relay I38 and energize electromagnet I01, to trip clutch I06, which will be locked in its operating position due to the locking up of the electromagnet over brush I45. The clutch, upon being actuated will remain in engagement through one complete revolution, and the electromagnet I01 will remain locked up until the first card selected from the supply I II operates the card actuated contact lever II1. Relay I38 will also be locked up over the same circuit which holds the electromagnet I 01 locked up. When the first card in the supply III operates its contacts, the locking brush I45 breaks contact, but electromagnet I 01 and relay I38 will be held operative from ground at I23 through contacts I20 and I22, contact I34 of relay I35, contacts I43 and I42 associated with electromagnet I12 and contacts HI and I40 associated with electromagnet I1I. Therefore, electromagnet I01 being held energized, the clutch I06 will remain in its driving position and the first card from the supply III will be advanced past the control brushes II3 to a position where it will actuate card actuated contact lever I98, while a second card from the supply I I I will be moved into association with the control brushes. This will occur at about the end of the second revolution of the shaft I08 driven through the clutch I08. At this point in the operation, ground at I23 will be connected through contacts I98 and 200, brush 202, disk 203 and brush 209 to electromagnet 25 (Fig. 2) to start the register shaft 82 in synchronism with the movement ofthe first card past the recording brushes I81. The same ground connection will be supplied to relay I11 which, upon energization, will be locked up'from ground at 255 (Fig. 2) through brush 256, contact disk253 and a brush 215 which breaks the ground connection from 255 by engaging a non-conducting portion of the contact disk 253 as the shaft 254 moves out of its normal position. The register shaft 82 will thus continue to rotate until the printer shaft 254 starts to rotate to print either a progressive or grand total, since the locking ground for holding the relay I11 energized is also connected to the electromagnet 25 to maintain it energized until either a progressive total or a grand total is taken.
In the operation of the device described thus far, cards from the supply III will be picked up and fed past the control brushes H3 and recording brushes I81 in synchronism with the driving of the register shaft 82, and the algebraic sum of the quantities punched in. each card will be put into the register until a card is found which has in the area thereof associated with either of the groups of control relays information which does not correspond with that in the-card which previously passed the control brushes II3. As long as the cards passing the brushes H3 and I81 agree in the areas thereof which are being compared, the relays 205, 206, 201, 208, 22I, 222, 223, 224, and 225 will remain locked up and the cards will be permitted to run continuously to control the register.
As soon as a card passes the control brushes H3 and does not agree in the compared areas thereof with the card at the same time passing the recording brushes I81, one of the pairs of relays 205 and 222, or 206 and 223, or 201 and 224, or 208 and 225, will fail to operate at the same time, and, therefore, will not lock up, thus indi eating that either a sub-group or main group of transactions has been completely entered in the register. With the control relays connected as shown in Fig. l, a progressive total will be taken when the cards disagree in the areas associated with relays 201, 208, 224, and 225; and if this occurs it is necessary to print the progressive total and return the register to indicate the amount printed. Upon the failure of the relays 201 and 224, or 208 and 225 to operate simultaneously, the ground connection for maintaining relay I12 operated will be broken and the contact lever I68 will not be attracted toward the electromagnet I12 and consequently will break the circuit between contacts I42 and I43, thereby to de-energize the relay I01 and contact will be made between the pair of contacts 250 to connect ground from I39 to the winding of relay I35. Relay I35 opens the operating circuit for the card feeding mechanism which is under control of electromagnet I01 to avoid starting the feeding of the following group of cards too soon, and also relay I35 over the same circuit will cause the release of relay I38, which, through its break contact, will connect ground from 244 at the register shaft through brush 89, and the contacts of relay I11 to the electromagnet 251 which operates the clutch 258 for the printer mechanism in synchronism with the register shaft after the input to the register has been controlled by the card at that time passing under brushes I61.
When, as in the present case, a progressive total is to be printed, the register must be returned to the position where it will indicate the same number as is printed at this time and then automatically the feeding of cards must again start. Therefore, the electromagnets 45 in the register mechanism must all be energized simultaneously so that their associated contact disks will be driven synchronously through one complete revolution to return them to their previous position. The ground connection to the electromagnets. 45 for energizingthem when a sub-total is to be taken is supplied originally from the brushes 29I associated with the printer shaft 254' which will connect ground to the brushes 82 associated with the contact disks 58. The brush 62 engages a conducting portion of the contact disk 58'at all positions except the 0 indicating position and thus as the contact disks 58 reach their 9 position, having all started to rotate at the same time, the selecting electromagnets 263 will be energized to control the printing mechanism, and shortly thereafter the disks 58, in arriving at their 0 positions, will bring a non-conducting portion of the disk into engagement with the brush 62'to normally stop the disks in their 0 indicating position. However, when a progressive total is being taken the contact disks 58 will not stop in their 0 indicating position, but will return to the position where they will indicate the number previously stored therein, since ground will thereafter be supplied to the electromagnets 45 through the contacts of de-energized relay 242, the ground connection for which was broken at relay 210, and through the locking contacts of the holding relays 24I, contact 281, progressive total relay 246, to brush 83 associated with the register shaft 82, which will break contact after the shaft 40 completes one revolution.
When the perforations in the area of the cards associated with the group of control relays, including relays 205, 206, 222, and .223, disagree, a grand total will be taken due to the failure of one of the pairs of relays to operate simultaneously. The failure of the pair of relays 205 and 222 to operate simultaneously, or the failure of the pair of relays 206 and 223 to operate simultaneously, will disconnect ground from the electromagnet I'll, thereby permitting the contact lever IBI to disengage contact I40 from contact I4I to break the ground connection to electromagnet I01 and to cause the pair of contacts 288 to become engaged to connect ground through them to the relay I35 which will lock up to brush 252 on the printer shaft 254 and through the break contact of relay I38, start the printer mechanism in the same manner as it was started to print'a progressive total. Ground will also be connected through the pair of contacts 288 to the winding of progressive total control relay 269 which will operateto break the circuit to relay 210 which, upon failure to operate, will also fail to operate relay 246 and since relay 245 will operate as soon as the printer shaft starts to rotate, holding relays 24I will not be energized, and relay 242 will be energized under control of brush 282 so that when the brushes 29I over the conductors 290 will supply ground to brushes 02 associated with contact disks 58, the electromagnets 45 will be energized and held energized only until their associated contact disks reach the 0 indicating position, at which time they will be de-energized since they are not connected through the contacts of the relay 242 to the holding relays 24I, and after a printing operation occurs, the register will be returned to the 0 indicating position.
When the supply of cards is exhausted, a grand total will be printed and the machine stopped with all of the parts in their normal position has a common ground with the electrom'agnet I01, it will also be de-energized and as described in connection with the other printing operations, it"will control the printing of the amount registered on the register and return the register and printer mechanism to their normal position.
