To an whom it may concern: y Be itlmown that I, Josnrn V. V xen BAUGH, a citizen of the United Stnt%"of America, residing at New York, in the county and State of New York, have invent cd certain new and useful Improvements in Accounting Machines, of whichthe following is a full, clear, and exact description.

This invention relates to improvements in accounting machines, and has for itselfject the provision ofan accounting machine of such character that a very large number of customers accounts may be kept without the necessity of separate registerin counters for each account or a complicated hookkeeping system. The machine may best bc understood by considering the present sysfein used .in retail store to whichthe nachine'is ingre particularly adopted. 5 I fi. In such a store it is the practise to' write out duplicateor triplicate sales slips giving the names and prices of'theiarticlesipurchased and the writtentotal of the amount.

section.

' One of these slips is usually wrapped'with the goods and the otherreteined'fonpost, ing or bookkeeping purposes. Gertein'sys terns have been devised in. which {the slips are themselves retained in clips andlform the record of the transaction, All of these systems are subject. to common disadvantages, namely, that mental addition by clerkfs frequently results in erroneous totals and that a lost slip causes an error in the account The. totalizing of any large number o fthe individual accounts on individual counters has proved impracticable-duet!) the fact that the number o faccounts necessitateszzin exceedingly multitudinous number of counters with the attendentcost and complication, In the present invention-1 provide n me..- chine whichicomprises two main parts, name? 1y, a computing section and en accoginting The accounting section olf the machine comprises a cabinet with index consisting of nanms on the topv thereof corresponding to the customers names or the nccountrnnmes. Positioned adjacent the names are movable index arms which are adapted to be positioned opposite any individual name on the index. Within the cabinet are a number of carriages each containing a numbcrof account currying members or unit ZLIHIS.

' Accounting section.

. The accounting section and mechanism. therein is shown in Figs. 1, 2, 3, 4, 5, 6, 7, 8, 9,10and11. v

. ln Fig. l. the accounting section A comprises a casing 50 substantially rectangular in. shape having a tray 51 therein (see Fig. t) which isslotted as shown in Fig. 1. This tray is adapted to receive removableindea plates 52, see Fig. 8, into'which-may be slipped slips of paper bearing the customers name. or other account designating data. The tops of the plates are sloped to facilitate reading. The group of name plates are covered by removable glass cover plates 53.

These groups of name platm comprise the.

index section of the accounting section. The tray 51 is slotted at the left of the groups of indiceswith slots 54 through which project indeai arms 55 having, sligh tlybelow each index arm and slidably thereby. an index carriage 56 which is supported -by rollers 57 on rails 58 which are suitably- -mounted in the casing (see Figs.

4and '9); Tot eachindex carriage is fasten'ed a pointer59' cooperating with the index name plates.

The normalposition of'the index arm is at the center of the inde-Xsection, see Figs. 1 and From this point thearm may be moved freely backward or forward in slots 54. Z.\djacent' each index arm carriage are two supplementary index carriages 61 and 62 (see Figs. 3(4. and 5). These carriages are adapted to be-moved in the direction of the arrows shown in Fig. 3 by the index arms upon a sliding movement thereof. The supplementary carriages are provided with supporting and guiding: rol ers whiehcooperate with thera-ils 58 (see Figs. 5 and 9). Each supplementary index carriage has attached thereto a metal bracket piece 63 which connects with unit arm carriages 64 and 64 (see Figs. 4, 5 and 9). The unit armcarriages are grouped closely together in order to avoid excessive length of the unit ann.. The unit arm carriages are provided with rollers 65 which rest upon supporting rails 66.

There. are groups of unit arm carriages 64 at the. left, as shown in Fig. 4, and other groups 64 at the right. The left and right hand groups are mounted upon adjacent rails 66 as shown in Fig. 9. Moving index arm to the right moves supplementary index carriage 61 to the right locking the supplementary carriage to the index carriage by means of gravity awl 67 engaging a locking pin on the in ex carriage (see Fig. 5). When the parts are in normal position the pawl is disengaged by abutting against pin 68. Fig. 4 showsin dotted lines the carriage 64 moved to the right. A movement of the index arm in reverse direction moves the right-hand carriage 64. The carriages are returned to normal position by returning springs 69. It will be understood that thei index arm 55 is moved until the pointer 59 stands opposite the desired name 0n the index section. Each unit arm carriage has a shaft 70 there- 'in*wh-ich' forms a support for a number of unitarms or account carrying members 71. The movementof the carriage is adapted to bring-a particular unit arm, corresponding to a particular customers account, to the dotted line position-as shown in- Fig; 4. After the index arm 55- has been moved to 'itsproper position the handle 55 .is desionof returns ring 76, thereby rocking releasing'mawl j7 1 so as to release lockingbar 78 and permits it to move to the left under the tension'of a spring 79 (see Fig. 9). The pawl 77' lies directly behind pawl 77 and is best shown in Figs. 13"and 14. The similar and parallel pawl 7'? is also released by the movement of the tripping bar. The locking bar carries a number of pins 80 and these pins are adapted. when the bar is moved to the left, to enter slots 81 in carriages 645, 64. etc.. and locks the same all in neutral position (see Figs. 4 and 10). In th s manner, after a particular unit arm is selected the unit arm carriage containing that arm and all other carriages whether the one operated by the same index arm or others. are locked and cannot be moved until certain further operations are performed. The locking bar is retained in left-hand po ator in. the computing sition by means of a locking plate or pawl 82.

The releasing pawl 77", which as previouslyexplained, is directly behind pawl 77 (see Figs. 10, 13 and 14), normally engages a notch in an arm 83 (best shown in Fig. 11). When the releasin pawl swings anticlockwise under the in uence of the left wardlmovement of-oar 7.5, -the arm 83 is released and swings anti-clockwise under the infiuence-of spring 8 1 (Figs; 10 and 11). This spring. 84.-is put .under tensionby; the movement of locking bar 7 8 to the left.- wlThe foregoing movement of-arm 83rele'ases pawl 85 from 'engagement with parallel (bar 86 (see Figs. 9, 10and11'1).-= J:

The unit arm is retained in position by a pawl 96 shown in Figs. 9 and 10.

Computing section.

The parts heretofore described "are adapted to swing a particular unit arm to the position shown in Figs. 12 and 15. It will be assumed that this unit arm already carries a total check representing an amount of 104.12. This amount is visible to the opersection after the unit arm has swung up into position. It will be assumed that the customer Whose .unit arm shows a total of 104.12 new purchases additional articles. The salesman writes the names of the articles on the original sales slip (see Fig. 30) 1 together with the item amounts. Similar written data is transscrioed to the duplicate sales slip by. carbon paper (see. Fig. 32). :The person operating the machine thennplaces. the original sales slip int'he sales slip carriage=l00 (seetFigs. 28 and 29) between the sales slip holder-.101 and-the back of the carriages. Thenperator then presses the 'sa-le'szslip -:caaq'iage-down the machine to the position: shown .sinFig'. 24. g The :carria'ge. 1QJ:;ltS= downward'ni'ovement brings a-pin 103 into engagement With a cam 10a-carried bycgthe sales slip holder and swings \thesales slip holder to closed position again'st-the =tension-'of-s ring=102 (see Figs. 28 and 29 i-Eilhsales s ipacarria'ge is provided with suitable guide rails cooperating with the guides shown in Figs-21 and 28i-and also with, smack-105 which cooperates with a gear 106 having a drum onwhic'h is a cable secured to a tension spring 107 (see Figs. 23-24).

This strip 50f papertis cut;ofi'-to dorm. the record slips or checks shown inrFig: 31 and these checks or slips are retained in' the box 118 shown in Fig. 23.- After'thesales slip carriage'has been depressed as far as it will go, the carriage is retained by--me'ans ofan e's' capement device 119 (see Fig. 25). The sales slip carried by the carriage is then in such position that a blank space on the sli opposite the printed ,words Previous ba ance brought forward is opposite the printing line of the adding machine printing segments 120. I

'The operator then reads the total check on the account carrying member and sets up the amount upon the 1 adding machine keys 121 and pulls the adding machine handle in the usual manner. Thereafter the individual items are set upon the adding machine and the handle is pulled after each item as is usual in adding machine operations. The amount carried forward is printed on the sales slip lay-carbon ribbon 122 (see 15). This ribbon is carried by rolls 123, 124 and is doubled over the type segments as shown in 122 (Fig; 15). This doubling of the ribbon is done to permit a printin of the total check as will hereafter'be descri d. Ribbon ed as shown in wee? 108 (Fig. 2.9) efiectsthe printing on the rec- 0rd slip. I i V v t T-hc item a'mount-s on the sales slip and record slip are rinted at eneh'actuation of the adding inac ine handle 125 by rockin the segments as shown in Fig. througi carbon ribbons and paper heretofore described ag'ainst a stationery platenv 130. Thc'rocking of the segments is performed by the 'adding machine printing operating, mechanism, which is of the type well known in theadding machine art-and particnlerly inthe Knistrom adding machine. Such on adding machine is shown in-Knistroni Patent No. 1,281,792. z 7

After each item amount is printed, the sales sli carriage is released by the movemeat. ,0" an escapcrnent 119' controlled by the adding machine handle as will now be described.

To transfer the new total check -to..the unit arm'I provide a supplementarycafrriage 176 (see Figs. 12 and 16 mounted on guide rails '154 and adapted at a suitable time in theoperation to b e moved by bell crank l77 from the full line position 'todotted line'position as shown in Fig. 12.

In this latter position a pawl 178 pivoted on the carriage engages a notch 179 in total check carriage. Upon the return of supplementary carriage the total check carriage is carried along with it as shown in Fig. 16. Bell crank 177 eventually contacts with pawl 176. (see Fig. 21) releasing member 174 and allowing apertured plate 170. to grip the new total check. Concurrently the total check grippers 156 are opened by pin 159 contacting with a pin 180 in slot in rail 154:, thereby shifting the controlling wedge plate 158 so as to open the grippers. The unit arm is now in the position as shown in Fig. 17. y

In order to print the customers name and address upon the sales slip, I provide suit able type characters 181 upon the rearof the unit arm. These type characters may represent any desired account designating data. 7

The final upward movement of the Slip carriage prior to printing the total amount has broughta high tooth 182 on slip carriagc rack into contact with a bent plate 183 and rocked this bentplate so as to set certain parts for the address printing operation.

Referring to Figs. 23 and 24, the slip carriagerack 105 has a high tooth 182 which when the slip carriagemoves to total position contacts with and moves a pivoted bent plate 183. This plate is pivoted upon a bell crank 185' andhas a pin 186 in engage ment therewith and is held in contact therewith by a spring. Upon high tooth 182 contacting with .hent plate 183, bell crank 185 is swung clockwise and by means of a roller .184: swings plate 130 clockwise and brin'gsQa roller 187 out of slot 188 and into cooperation with abutment 189. (See Fig.

2-3.") Uponthe next'upward movement of:

plate 13Q 'which imparted by shaft 128, the roller 187: will. lie-moved up, thereby rocking shaft-190 and arm 191 counterclockwise- 'Ihisarm 191 has -a forked end cooperating with pins 192 on ends of roller :113. These pins extend into camming guide slots 193, best shown in dotted lines in Fig. 24. .The movement of arm 191 from the position shown in 'Fig. 24; to that shown in F in. 23 .thereby concurrently rolls the roller; 1 The .platen roller 113 cooperates with-the carbon ribbons and the type 181 upon. the rear otthe unit arms and prints the customers name and address upon the sales and record slips as shown in Figs. 30 and 31-. Inprder to provide a firm backingfor .the .unit arm during the address printing operation I provide a swinging abutment member 195which is swung from the open to the abutment position shown in Fig. 21 by means of the bell crank arm 17 7. The abutment-is normally maintained away from the unit arm by means of a spring shown in Fig. 21 to permit the roadinn of; the number on the total check.

The movement ofaddressing roller arm 191 through a pin 196 and sloping slot in plate 197 is adapted to operate cutting off knife 117 and cut off a previously printed record check. The cut oil' check thereafte drops in box 118 where it is retained.

Upon the completion of the address print ing plate 130 returns to normal position under the influence of a return spring 198.

After the address printing operation is completed escapement pawl 136 is released from first high tooth to second high tooth shown in Fig. 25. This permits the slip carriage'to move to xtreme upper position and feed forward the record check paper through the knii es 116 and 117 and thereby space the record checks apart so that the customers name and address is not severed by the knives on subsequent cutting of paper. Just prior to the aforesaid final down a link206 and-rocks shaft 91.

movement of the slip carriage, the supplementary carriage 17 6 has been moved to the left to the position shown in Fig. 16. The end wall of the total check carriage has impacted against a spring pressed plunger 200 and forced this plunger to the left and by means of the pointed end thereof has cammed the unit arm retaining pawl '96 to such position as to release the unit arm and W permit it to return to position in the accounting section. In Fig, 16 the arm is shown in position in the computing section just prior to its return to the accounting section.

After the unit-arm is released the slip carriage moves to extreme upper position bringing a pin201 shown in Figs. 29 and 28 into contact with a pivoted mem'ber'202, thereby rocking pawl 178 out of notch 179 in total check carriage 153. The total check'carriage is then'returncd to normal position by means of a spring 203 (seelFig. 12). {Pivot/edmember 202 through a link 203* connects with the'pivoted bail 204 which carries locking plate 82, thereby releasing locking plate 82 from. engagement with the notch in bar 78 (see Figs. 10 and 28). a

To restore the parts in the accounting section the end of shaft 128 is provided with a cam 205 which through a bell crank dra ilys 0 this shaft is fastened a dog 207 (see Fig. 12) which upon rocking clockwise contacts with a pin 208 and rocks arm 89 clockwise. restoring parallel bar to normal position. Pawl 209 carried by this arm contacts against a roller 210 carried by forked arm 211. thereby rocking forked arm clockwise and through a pin 212, restoring latch arm 83 to normal position in which it-is latched by pawl 77. Parallel bar 86 also latches over 85 as shown in Fig. 9. Inasmuch as pawls 77 and 77 are connected to bail 204 by means of springs 213 and 214 (see Figs. 13 and 14). these pawls will not be drawn up into latching position until bail 204 is raised at the end of the series of operations in thecomputing section. Therefore 83 will not be latched by 77" except after the operations in the computing'section have been completed. When bail 204 is rocked and plate 82 is lifted from the notch in bar 78, the bar 78 will be drawn to the right under the tension of spring 84 which is put under tension by the rocking of member 83, to which it is attached. Spring tension of spring 84- overcomes the tens on of spring 79 which is alight spring This bar 78 will then be locked in normal position by pawl 77 and the unit arm carriages will then return to normal position under the influence of springs 69. Previous to th s return of the carriages the unit arm which was in the computing machine had completelyreturned to normal depending posi tion. A

It has been found that the unit arms in returning have a tendencv to rebound from vertical depending position. In order to prevent this undesirable action and at the same time provide means for removing any desired unit arm for repair or for the replacement of another set of type 181. designating a different nameor revised address. I. provide the construction illustrated in Figs. 6. '7 and 9. Each unit arm 71 has at its upper end two metal plates 71* and 71" which are notchediat the side to receive the supporting shaft 70. Below this shaft is a cross bar 215 which is suitably fastened to the unit arm'rcarriagetbracket 64 and 64. This cross bar is stiffened by plates 216 which tie it to the shaft. Cross bar 215 is grooved upon' its lower-edge as shown at 217 and is provided with-a resilient bumper block218. Each unitfarm carriesa retaining paw-l QIQTWlllCh is free to move en'dwim to a-limit'edfeirtent' 0n the unit arm and which has a. projection adapted to cooperatewith groove 21?. Over the shaft is slipped a retaining fork 220 which through a spring 221 connects with retaining pawl 219. Retaining fork has a projection 222 to permit the fork to be gripped and raised'when it is desired to replace the unit arm. Upon 'the return of the arms to vertical position the resilient bumper 218 takes up a part of the shock. Thereafter the spring pulled retaining pawl 219 engages in groove'217 and locks the arm in vertical position,- therebv preventing the objectionable rebound. The complete cycle of operation having been traced for one operation, it is sufficient to state briefly that credit operations can also be performed. The adding machine is provided with a credit kcv usually known as a subtracting key. This is shown at 137 in Figs. 2 and 1. In a Creditlransaction the index arm is first selected and positioned in visible posi tion in the computing section. The customers name and other data is written on the sales slip and the ar ount of the account is set'forth on the adding machine kevs. Thereafter theamount to be paid or subtracted is set up. the credit key depressed and the machine operated in the usual mun ner. This operat on prints the sales slip as hown in Fig. 33 printing on the slip the item B. indicating the amount is a received amount. The subtraction is carried out and the new amount or subtrahend. i 0. new amount of account. is printed on the slip and transferred to the unit arm in the usual manner.

In Fig. 32 I have shown the sales slip which is the duplicate slip. which is used by the clerk as-a guide in setting up the item amounts as slotted. This slip is not
