(Cl. 23S-6) The present invention relates to bookkeeping or accounting machines and more particularly to that type used in savings banks for recording the customary deposits and withdrawals. The
present invention is intended to diminish the amount of manipulation necessary in operating such machines. To this end the present invention includes structure which enables a movement of a balance lever to set up the mechanism for taking a proper algebraic total from the balance totalizer, and also to start the machine. The provision of this mechanism makes it unnecessary to press a motor bar after the lever is adjusted.
With this and incidental objects in view, the invention includes certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form a part of this specication.

GENERAL DESCRIPTION The mechanism illustrated herein discloses a machine having one adding and subtracting or balance totalizer of the customary type embodying reversely rotated wheels. It also includes a row of interspersed adding totalizers to accumulate separately the deposits, withdrawals, pcsitive old balances, negative old balances, positive new balances, and negative new balances, and two other rows of such totalizers for accumulating the various classifications of deposits and withdrawals.
When a patron presents his passbook for the purpose of making a deposit, the old balance is entered in the balance totalizer, as Well as in one of4 the special totalizers assigned such old balance. The deposit is then entered in the balance totalizer and in its special totalizer. The new balance is then taken from the balance totalizer by a lowering of the balance lever from its add to its balance position. The lowering of this lever causes the proper one of two blind new balance keys to be depressed, which in turn causes the selection of one of two blind keys for selecting the proper side of the balance totalizer. Further movement of the lever causes the depression of the selected one of these latter blind keys and thereby positively moves a selecting rider for the balance totalizer to its proper position. The selection of these blind keys and the resulting shifting of the selecting rider for the balance totalizer is controlled by a suitable overdraft mechanism with the result that a proper algebraic total is taken. The very last portion ofthe movement of the balance lever causes the motor clutch to be released to start the machine.
Near the end of the operation of the machine the balance lever is automatically returned to its home position and the machine comes to rest.
DETAILED DEsoRIIrIoN K eg/board The keyboard for the present machine is shown diagrammatically in Fig. 1 and includes amount keys |50, two rows of special totalizer keys l5! and a row of transaction keys bearing appropriate legends. In this transaction bank the keys D and W represent deposits and withdrawals respectively and the keys POB and NOB represent positive old balances and negative old balances respectively. The two blind keys situated near the center of this bank represent the positive and negative new balances.
A key stem 24 is situated to the right of the transaction bank and cooperates with two blind keys 20 and 22 used to shift the operating mechanism for the balance totalizer so that amounts may be entered thereon algebraically. A kind of operation lever HH is provided to take the totals from the various totalizers for the transaction bank and for the two banks of special totalizer keys. |02 also are provided for use in taking totals in these banks. to select a particular totalizer when it is desired that the total be taken therefrom. The present invention, however, is not involved with the details of the taking of totals from any of the totalizers in these three rows, so the operation of these levers is not given.
The special totalizer keys |5| in the two lefthand rows control only their respective totalizers, while the transaction keys in the iighthand row control not only the respective totalizer assigned to each, but further control the operation of the balance totalizer. It must be remembered that the kind of operation lever lill is used in taking totals from the totalizers for the three rows of totalizer selecting keys but is not used when a total (new balance) is taken from the balance totalizer, for such operations are performed with the lever MI Vin its addition position.
y. For taking totals from the balance totalizer, a balance lever |49 is provided. When this lever is moved to its balance position it depresses the key stem 24 and with it one of the blind keys 20 or 22 to Yshift the balance totalizer. Movement of this lever to its balance position also otherwise completely conditions the machine for a balance operation and starts the operation without any further manipulation of the keyboard.
During itemizing operations the machine is started when any one of the four keys in the transaction bank is depressed, these keys in the present machine being constructed as motor keys.
Diyerentzal mechanism Vamount differential and Fig. 9 a few parts of the transaction differential. Referring to Fig. 2, the differential includes two complementarily movable arms |53 and E54 brought together through the action of complementary gears to adjust a minimum movement segment |05 under the inner end of a depressed amount key 50. These parts are actuated by a suitable pinion secured to a shaft |56 oscillated during each operation of the machine. The detailed movement of these parts is not given, since it is fully shown and described in the United States Patent No. 1,792,559 issued to Ernst Breitling on February 17, 1931. It might be noted, however, that the particular form of planet gearing shown in Fig. 2 is not present in the patent but is shown in a later patent disclosing the mechanism for taking totals in this type of machine. This later patent isv numbered 1,899,455, issued to Ernst Breitling on February 28, 1933. For an understanding of the present case it is sufficient to say that the movement of the complementarily movable members |43 and |44 causes a movement of a large gear |51 to an extent commensurate with the value of the depressed amount key |50. The positioning of the minimum movement segment |135 causes a positioning of its corresponding amount type wheel Three totalizer coupling leversV The function of these levers is Y through a train'of gears |47, |48, |52, |54, |55, and |55` and a rack |5i, the gear |41 being driven by the segment |45 through beveled teeth appearing on both members.
The differential mechanism for the transaction banks is partially shown in Fig. 9 and includes complementarily movable members |05 and |07 and a minimum movement segment |05. As is customary in the art, the diiierential mechanism for these banks controls the relative positioning of the various totalizers and the actuating mechanism, so that an amount set up on the keyboard will be entered in the appropriate totalizer under control of the totalizer selecting keys.
However, since the details of this differential mechanism are notv necessary to an understanding of the present invention, they are not shown.
Totalz'aers The machine on which the present invention is shown includes three rows of interspersed totalizers (Fig. 2) situated radially about a central shaft |46. For identication these rows are numbered I, II, and III. Each of these rows customarily contains nine totalizers. In the present instance two of the rows contain nine totalizers assigned to the two rows of special totalizer ykeys and the third row contains six totalizers assigned to the transaction keys. The construction of thesel interspersed totalizer units and the operation thereofV are generally well known in the art and a form corresponding very closely to that used in the present mechanism is shown and described in U. S. Patent 1,398,935 issued to Bornkessel et al. on February 7, 1933. Details of this mechanism, however, are not necessary to an understanding of the present invention, so they are not shown.
There is also provided a balance totalizer consisting of only one totalizer unit but having two reversely rotating wheels in each decimal order. This totalizer unit is. numbered IV (Fig. 2) and is better shown in Figs. 3, 4, and '7. It includes two reversely actuated wheels`5i and 59 (Fig. 7), a pair of which is provided for each decimal order. The operation of these wheels is briefly as follows:
The differential rotation of large gear |57 (Figs. 2 and 3) commensurate with the value of the numeral key depressed in that particular decimal order is transmitted directly to pinion |58 (Fig. 3) and from there to pinion E59. Since at the time of this operation pinion 50 is engaged with pinion |59, the motion will be transmitted to the former and to sleeve E53 (Fig. 7) secured to this pinion. A rider 59 is loosely mounted on a shaft |30 and is slidable longitudinally of the sleeve |53, as clearly shown in this iigure. The rider has an Yupwardly extending prong protruding through a longitudinal slot in the sleeve |53 and is adapted to be moved longitudinally into the plane of either of the totalizer wheels 5l or 59 by a longitudinal movement of shaft |30. When the rider is so moved it is in a position (see Fig. 4) to rotate one of the totalizer wheels upon rotation oi the pinion 59 and sleeve |53.
The reverse rotation of wheels 5'! and 59 is made possible by the gear 5| on the shaft |35 (Fig. 4) and gears 52 and 55 (Fig. '7) connected by a sleeve 53. When a rotation is imparted to the wheel 58, the movement is transmitted through a sleeve 58 and a gear wheel 49 to the wheel 54, sleeve 53, gear 52, and then to gear 5|. Rotation of the gear 5| causes rotation of a gear 48 attached to a sleeve 55, on which the totalizer wheel 51 is mounted. It will be noted that gear is sufficiently broad to mesh with gear 52 and also with gear 48.
Each of the totalizer wheels 51 and 59 Carries a tooth |39 (Fig. 4) sufliciently long to strike a finger 32 depending from an assembly of parts |33 appearing directly over the totalizer Wheels in Figs. 4 and '1. A long tooth of an actuated totalizer wheel displaces the nger |32 whenever the long tooth |39 is moved through zero. This movement of the lingers 32 is for the purpose of transferring units from one order to another and is assisted in this action by discs |6| and |62 and the mutilated gears |66 and |31 appearing in Fig. 4. However, since the details of this mechanism are not necessary to an understanding of the present invention they are not given.
It will be noted, however, that the finger |32 (Fig. 7) cooperating with the totalizer wheels 51 and 59 of the highest decimal order is pinned to the shaft |34 so as to impart a slight rotation thereto whenever the wheelsof highest order pass through zero.
overdraft mechanism The machine on which the present invention is shown includes a device commonly known as an automatic overdraft mechanism. This mechanism causes the totalizer to add a unit in the lowest decimal order whenever the totalizer wheel of highest order passes from zero to 9 or from 9 to zero to correct the inaccuracy appearing in totalizers of this type whenever they are carried through zero to a negative quantity or returned through zero to a positive quantity.
The mechanism also includes the additional feature of allowing this additional or fugitive unit to be added in the units order only when an actual overdraft occurs and not when the totalizer passes from 9 to zero by exceeding its capacity in a positive direction or by passing from zero to 9 after having been overdrafted during a previous operation.
This mechanism is illustrated in Figs. 5, 6, '1,
and 8. Referring to Fig. 8, it is seen that whenever either of the totalizer wheels 51 or 59 in the highest decimal order passes through zero it strikes the finger |32 pinned to the shaft |34 and imparts to this shaft a counter-clockwise rotation. A sleeve member |63 is situated on the right-hand end of shaft |34 and is connected thereto by a pin and slot connection (see also Figs. 6 and 7). This allows the shaft |34 to be shifted axially without corresponding movement of sleeve |63 but causes the sleeve to receive whatever rotation is imparted to the shaft. VThis sleeve is connected to a gear |64 by a spring |65, the spring being secured to bothV of these parts, and suiciently strong that a partial rotation of sleeve |63 will be imparted bodily to gear |64 if the latter is free to rotate. The gear |64 is loosely mounted on shaft 34 and has a shoulder |66 (Figs. 5 and 8) lying in the vertical plane of a shoulder |61 on the sleeve |63. These two shoulders normally lie some distance apart, as shown in these figures. With this construction, when the finger 32 (Fig. 8) is given a rotation by one of the totalizer wheels 51 or 56, a corresponding rotation is imparted to the sleeve |63 which,
through spring |65, will rotate gear |64 if the same is not positively held against rotation. If it is so held, the spring |65 will be tensioned and upon passage of the long tooth |39 out ofthe path of the finger |32 the shaft |34 will spring back to its original position, relieving the tension in the spring. A segment |68 (Figs. 5 and 8) is loosely mounted on a shaft |69 and carries a stud |12 having pivoted thereon a. dog |13. A sleeve member |15 is also loosely mounted on shaft |69 and carries a four tooth restraining wheel |10, Vfour radial teeth |16, and a mutilated gear |80. 'I'he four tooth restraining wheel |10 lies in the vertical plane of a dog |13, which dog is constantly held against the wheel by the tension of a spring |14 secured to the dog and to a projection on the left side of the segment. 'I'he four teeth |16 are disposed around the sleeve |15 equidistantly and lie in two different planes. As shown in'Fg. 8, 'these teeth lie alternately in two planes. An arm 8| is secured to shaft |30 (Figs. 6 and 8) and lies in the plane of two of the teeth |16 when the balance totalzer is set for addition, and in the plane of the other two teeth' when the totalizer is set for subtraction. The operation of these parts is briefly as follows:
When an'overdraft appears in the register, the shaft 34 is rotated counter-clockwise, causing a counter-clockwise rotation of gear |64 and clockwise rotation of segment |68 as well as wheel |10, teeth 16, and gear through the operation of dog |13 by the gear |68. If the sign of the balance in the balance totalizer is positive at the beginning of this operation, the arm |8| will be lying out of the plane of the tooth |16 situated closest to it at this time. 'Therefore the segment |68 will be free to rotate, upon rotation of shaft |34. This causes a rotation of the sleeve |82 (Fig. 1) as well as the transfer eccentric |83 to enter the fugitive unit in the lowest decimal order. The precise manner in which this unit is entered is not necessary to an understanding of the present invention and will therefore not be described.
Upon the return of shaft |34 to normal position, by parts of the transfer mechanism in the highest decimal order, the segment and dog |13 will return to their original position, the dog |13 ratcheting over one of the teeth |10 to allow the wheels |10 and |80 and teeth |16 to remain in their moved positions. This places one of the teeth |16 of the other plane in a position to have its movement restricted by the arm 8| unless the arm and shaft |30 are moved to their opposite lateral positions for the next operation involving passage of the highest wheel through zero.
During the normal operation of the machine, when the balance totalizer is in a positive condition and vis overdrafted to a negative condition, the arm |8| will not prevent the entry of the fugitive unit. Likewise when the totalizer is in a negative condition and is returned through Zero to its positive condition, the arm |8| will not prevent the entry of the fugitive unit, since the four teeth 16 are rotated 90 degrees by each overdraft passage of the totalizer through Zero. Thus as long as the operation of the machine involves transactions causing the balance totalizer to pass through Zero postively and negatively in alternate succession, the arm |8| will have no restraining action at any time, the totalizer being positioned alternately in its adding and subtracting positions during these operations involving the overdraft. However, should the totalizer have its capacity exceeded in either direction, the arm |8| will be effective to restrain the entry of the fugitive unit by lying in the path of a tooth |16 and thereby causing gear |64 to be held against rotation until the long tooth |39 passes the inger |32 and the springy |65 rotates shaft and finger |32 to normal position. s
When taking a negative new balance from the totalizer, the adding wheels are left standing with a series of 9s thereon. This is because the subtracting wheels are turned to Zero when taking a negative new balance. Therefore, when entering a positive old balance on the adding wheels immediately following the taking of a negative new balance, the highest order totalizer` wheel will pass from 9V to zero, that is to say, thcsame as though the totalizer exceeded its capacity. This will trip the overdraft mechanism to add one into the units order to correct the balance therein. This result will be obtained becausea shoulder |16 will not be in the path of the arm I8 and therefore IBI will not suppress the entry of the fugitive one in the totalizer. As pointed out above, the suppressing arm |9| is effective only when the sign of the total in the-totalizer is not changed in the totalizer. When the totalchanges its sign to negative, a shoulder |16 is placed in the path of the arm IBI. Subsequent taking of a negative total does not change this condition, but subsequent shifting of the totalizer rider to the positive side of the `totalizer for entering the .old balance shifts the arm |8| outof the path of the shoulder |19, so that when the highest order wheel passes from 9 to zero, one is added into the units order, and a correct oid balance will result in the balance totalizer, even though the wheels were all standing with 9s thereon before the old balance is entered. The totalizer is also automatically corrected when entering a negative old balance following the taking of a positive new balance.
The operation of this overdraft mechanism is given only in a general way, since a very similar structure is fully shown and described inthe above mentioned patent to Bornkessel et al. See particularly Figs. 16 to 21 of this patent.
Ocerdraft control of totalieer selection Fig. 8 also discloses mechanism -for causing the overdraft mechanism to y automatically select either of two totalizer selecting keys for depression. The mechanism operates in such a manner that whenever the balance in the balance totalizer is positive, one of the two totalizer selecting keys is selected, and whenever the balance is negative, the other totalizer selecting key is selected. In the present instance the keys selected are the blind positive and negative new balance keys situated in the transaction bank and used to select either of the two new balance totalizers for separately accumulating positive and negative new balances. As above described, whenever the balance totalizer passes from positive to negative or vice versa, the gear |80 receives a 90 degree rotation. By means of the mutilated construction of this wheel |80 (Figs. 6 and 8) a 90 degree rotation thereof will cause a 60 degree rotation of a wheel |83 and a disc |85 connected thereto by sleeve |85, the parts |84 to |86 being loosely journalled on shaft |81. A triangular cam groove |98 is cut in the disc |05 and is so situated that it moves a roller |89 in one direction or the other during each 60 degree rotation. These movements of the roller |89, it will be observed, are alternate, so that each time the gear |84 is given a movement, the roller |39 will be moved in a direction opposite to its last movement. The roller |89 is situated on the upper end of a bell crank |90 connected by a link |9I to a lever |92 connected by a sleeve |93 to an arm |94 having pivoted thereto a vertical link |95. Itis now obvious that 60 degree rotations of gear |84 will move link upward or downward depending upon its previous movement. The link |95 is connected to a lever |99 (see also Fig. 13) pivoted on a stud |91 and connected to a detent slide 91. The lever |93, together with an arm |98, supports the detent slide 91 for movement in the key bank. Two sliding levers 98 and 99 are pivotedl to the slide 91 and are tensioned for outward movement by a spring' |99 connected to each. These levers 98 and 99 have slots adapted to embrace studs |00 and |0| on the blind new balance keys and are restrained in their outward movement by the studs I 00 and |0l. Eachof the levers 98 and 99 has a long prong adapted to cooperate with stud 99 (Fig. 13) on the upper arm of the bell crank 94 pivoted on the stud 95. Each lever also has a short prong ad-apted'lto Contact studs |00 and I 0I when the levers lie in a position where their long prongs cooperate with the stud 99. By this arrangement of parts it is evident that when the link |95 is in its upper position, the detent 91 will lie in its lower position, where the long prong on lever 98 will contact stud 90 and the short prong will contact the stud |00, so that upon the clockwise rotation of the bell crank 94 the blind positive new balance key will be Vdepressed and when the link |95 is moved to its lower position by the balance to'talizer being overdrafted, the slide 91 will be raised to its upper position where the long prong on the lever 99 will contact the stud 93 and the short prong will contact stud |0I, so that upon clockwise moving of the'bell crank '94 the blind negative new balance key will be depressed.
Totalieer selection for interspersed adding totalzzers The various interspersedl totalizers situated in rows I, II, and III (Fig. 2) are selected for operation Aby the three rows of totalizer selecting keys shown in Fig. 1, as is customary in key set machines of this general character. The differential mechanism situated in these keybanks (Fig. 9) shifts mechanism in the totalizer assemblies, so vthat when the totalizer shafts are moved to engage the totalizers for actuation,` the desired totalizer in each row will be coupled with the actuating mechanism.
The segment |05 that is dilferentially positioned under the end of a depressed totalizer selecting key corresponds to the segment 41 in the above mentioned Breitling Patent 1,792,559 and is connected by a short sleeve 300 to a segment 290 meshing with a pinion 29| secured to a short sleeve 292. A segment 293 also is secured to the sleeve 292 and meshes with a pinion 290 secured to a drum 295 rotatably mounted on shaft 34. As shown in Fig. 9, this drum carries a helical groove in its surface in which rests-a roller 290 mounted on a bent arm 291 secured to a plate 300 by a sleeve 298. As better shown in Fig. 10, the plate 300 embraces restricted portions in shafts |30 and 305, so that movement of the plate 300 to the right or left will impart a corresponding movement to these shafts.' Shaft |30 is Vgrooved to accommodate riders |00, which connect the actuating wheels 50 with the totalizer wheels 59, and shaft 305 carries a longitudinal groove 306 (see also Fig. 2) and notches 301, one for each decimal order, which constitute an aligning means, so that only the totalizer wheel aligned withV rider |00 will be free to rotate with the actuating wheel 50. Y
By the above mechanism, when the segment |05 is adjusted by operation of the differential mechanism as fully described in the Breitling Patent 1,792,569, the segments 290 and 293 are correpondingly adjusted and rotate drum 295. Such rotation adjusts plate 300 bodily to the right or left, causing a corresponding adjustment of the shafts |30 and 305. In this manner the various totalizers are adjusted under control of the depressed totalizer selecting keys.
Selection of the proper side of the balance totalizer for adding and taking the new balance This mechanism is disclosed in Figs. 11 and 15. As heretofore mentioned, the six keys in the transaction bank control the selection of the positive and negative sides of the balance totalizer. This control is exercised through the provision of a detent slide I (Fig. 14) pivoted on two arms for movement in the key bank in the customary manner. This slide I0 has six cam portions, three of which cooperate with the deposit, positive new balance, and positive old balance keys to select thev positive side of the balance totalizer, and three cams cooperating with the withdrawal, negative new balance, and negative old balance keys to select the subtracting side of the balance totalizer. The depression of any one of the rst mentioned keys causes the slide |0 to be moved upward in the key bank, while depression of any one of the last mentioned keys causes the slide to be lowered. This raising or lowering causes a corresponding movement to be imparted to a link II pivoted to the slide |0 and to an arm I2 pivoted to the lower end of the link I I. This causes movement of a lever I3 (Fig. l2) connected to lever I2 by a sleeve 204, and movement of a link I4 connected to the lever I3, and further causes oscillation of a lever I5 connected to the link I4 and pivoted on a stud 203. Oscillation of the lever I5 causes an upward or downward movement of a slide I6 supported by the lever I5 and by an arm 202. Slide I6 has levers I1 and I8 pivoted thereon and pressed outwardly by the tension of a spring 205 connected to both. The levers |1 and I8 each have along and a short prong, the long prongs being-adapted to contact the underside of a stud 23 on the key stem 24, while the short prongs are adapted to contact studs I9 and 2| on blind keys 20 and 22 situated on either side of the key stem 24. It is apparent, from inspection of the drawings, that when slide I6 is moved to its upward position by depression of one of the three keys for selecting the positive side of the balance totalizer, the short prong on the lower lever I1 will engage stud I9 on the lower blind key 20 and the long prong will engage the stud 23 on the key stem 24. Likewise when any one of the three keys for selecting the subtracting side of the totalizer is depressed, the slide I6 will be lowered to the position shown in Fig. 12 and the upper lever I8 will contact the studs 2| and 23 for depressing the blind key 22. A slide 206 (Figs. 11 and 15) is suspended on arms 201 and 208 for the customary movement in its bank. This slide 206 has two cams 209 and 2|0 situated under studs I9 and 2| on the blind keys in this bank. From an inspection of Fig. 15 it can be seen that when the blind key is depressed, stud I9 will engage cam 209 and lower the slide 206, whereas when blind key 22 is depressed, stud 2| strikescam 2|0 and raises slide 206. A pawi 2|| is pivoted at 212 and is held by a spring 2I3 in engagement with eitherpf two notches in slide 206. This pawl is provided so lthat this slide 206 will be held in either of its positions until positively moved to the other position by depression of one of the blind keys. A segment 2 I 4 is pivoted at 2 I 5 to the key bank and carries a stud 2I6 lying within a slot in the slide 206. A segment 2I1 meshes with the segment 2 I4 an-d is secured to another segment 2I8 lying adjacent thereto. Segment 2|8 meshes with a pinion 2 I 9 secured to a gear 220. By this train of connections movement of slide 206 causes a rotation of gear 220 and a pinion 22I (Fig. 1l) meshed therewith and rotatable on shaft 60. Pinion 22| has beveled teeth 222 secured thereon and meshed with cooperating beveled teeth on a smaller pinion 223. This small pinion 223 is pivoted on a stud 224 secured to a sleeve 225 surrounding shaft 60. Another pinion 226 is loosely mounted on sleeve 225 and meshes with a segment 221 secured to a sleeve 228 having a tongue connection with a drum 229. The drum 229 is connected by a link 230 with the kind of operation lever |4| shown in Fig. 1. Since this lever |4| remains in its position shown during all the operations described herein, the drum 229, sleeve 228, segment 221, and pinion 226 remain stationary at all times insofar as the description of the following operations is concerned.
Reverting now to the movement imparted to the pinion 22I by depression of one of the blind keys 20 or 22, it is seen that rotation of the pinion 22| causes rotation of the small pinion 223 and sleeve 225 in the same direction. This causes a corresponding rotation of a pinion 23| secured to the opposite end of the sleeve 225 and to a helical cam drum 232 having teeth meshing with pinion 23|. Rotation of this drinn 232 causes a roller 233 lying within its groove to be shifted laterally. This roller is connected to an arm 234 secured to shaft |40, so that rotation of the drum 232 by movement of the above described parts shifts the shaft laterally. Shaft |40 is secured to a frame plate 235 carrying shafts |30 and |34, the lateral movement of which selects the adding or subtracting side of the balance totalizer as clearly shown in Fig. 7.
From the above it is seen that depression of the deposit, positive new balance, or positive 01d balance keys, followed by depression of the key stem 24, causes the balance totalizer to be conditioned for adding, whereas depression of the withdrawal, negative new balance, or negative old balance keys, followed by depression of the key stem 24, causes the balance totalizer to be conditioned for subtracting.
Totalizer engaging and disengagzng mechanism The means of engaging and disengaging the totalizers shown in Fig. 2 involves mechanism to move the totalizer wheels toward the central shaft |45 by swinging the wheels about shafts 236 or 254 as a pivot. This mechanism includes a cam 304 (Fig. 9) secured to shaft 34 and cooperating with rollers 302 and 303 on an arm 30| secured to shaft 236. This shaft 236 is secured to the totalizer frame so that upon rotation of cam 304 the arm 30| and totalizer frame will oscillate about shaft 236 as a pivot. A side view of these parts is substantially the same as the showing of parts 25| to 254 (Fig. 3). This oscillation of the totalizer frame causes the actuating gears 50 (Figs. 2 and 3) to be engaged with intermediate gears 231 that are rotated differentially through gears 238 by the large differential gear |51 under control of a depressed amount key. During adding operations totalizers are engaged for `actuation just before .the differ'- ,ential mechanism returns home from its moved position, and are .disengaged at the .end of such return movement, while for total taking a-selected totalizer line is engaged at the beginning of a machine operation and is disengaged after 4the differentials have been actuated to their moved positions. For sub-totalizing the totalizers 4,are engaged at the beginning of the operation vand are left engaged until near the end of the operation, as is customary, and for non-adding operations they remain disengaged during the entire operation. The mechanism for controlling lthe timing of these four different types of operation does not forma partof the present invention 5.
and is therefore not shown.
It might be here mentioned that one engaging mechanism is provided for the adding interspersed totalizers in rows I, II, and III and a separate engaging mechanism is provided for the balance totalizer. 'By such provisionA it is possible to have the balanceA totalizer engaged while the other totalizers are disengaged and vice versa for the purpose of transferring totals.
Conditioning the machine ,for a balance-operation When it is desired to take a balance (taking va total from the balance totalizer) it is necessary only to move the balance lever |49 from its add to its balance position. This completely conditions the machine for a balance operation and releases the motor .clutch and closes the motor switch to start the operation. During the lowering of this lever three separate functions are performed oneafter the other. The first is that of depressing one of the blind keys in the transaction blank for the purpose of selecting the proper transaction totalizer into which the balance will be transferred and for shifting the slide I (Fig. 12) to couple the proper blind key 20 or 22 for depression to properly shift the balance totalizer. It will be vremembered that the selection of the blind key in the transaction bank and the consequent'selection of theblind key 20 or 22 is under control of the overdraft .Y
mechanism above explained.
The -initial downward movement of lever M9 raises link 2.69, rotating lever 2t! counter-clockwise about its pivot |31 and lowering linkfZ-BZ. Link 262 at its lower end is pivoted to a short arm253 secured to shaft 261i having also secured thereto another short arm 255 in turn pivoted to link Bea. The lowering of link EEZ-therefore lowers link Q30. as well as an arm 266 pivoted at the upper end of link 93a and journalled on shaft 21. Lowering the arm 266 causes clockwise movement of bell crank 94 about its pivot ,95, due t0 the pin and slot connection between .the bell crank and arm 266. This clockwise movement depresses the selected one of the blind keys and adjusts the detent lll to its upper or lower position as heretofore explained.
rIhe initial movement of lever lllg'also adjusts the timing mechanism for engaging the'balance totalizrer, so thatit will be engaged and disengaged at the proper times for total'tagking. As above explained, this timing mechanism does not form a part of the present invention and is therefore not shown,
Continued movement of the balance lever |49 causes the upper end thereof to Contact and move roller .2?51 (Fig. l2) mounted on an arm 268 secured to a short vshaft 269. This movement rotates shaft 259 counter-clockwise as wellias a short arm Z'ilalso securedl thereto. 'Firearm-,21D
lies over the pi-n21l secured on the inner'end of theqkey Astem '24 and therebyjpulls the key .stem into its depressed position. As .above explained, this movement ofthe 'key stem shifts the bal-ance totalizer under control of `the overdraft mechanism.
As .the balance lever is gi-ven its last increment of movement, 'a :stud 212 secured on an ear on :the lower end of the lever contacts and'moves a release pawl 213 :piyoted on a stud l.21.4. This movement releases a clutch disc 2.15 .to theaction of -a spring 216 to engage the drive shaft of the machine with 'the motor and to raise a switch ,lever 2111 to vclose the V.electric circuit, :Since the details of the lmotor clutch and switch mechanisms arewvell known inthe art, yno further de.- tail thereof is given.
The balance lever 14.9 may he returned to its add position near the end of-the operation by any sui-,table mechanism. `exampleci such mechangism is disclosed in the `United `rStates lPatent 1336;.067 issued to Samuel Brand-'on November ,19, V1,929. However, -since the specific formzof return mechanism .is not essential to an understanding `of V.the present invention, it `has vnot beenshown.
Machine release for adding 4opera-tions Duringitem entering operations involving the depression of transaction keys it is necessary only to press vthe proper rvarnount keys together with theiappropriate totalizer key l5! and the appro- -priate transaction totali-zer key, The depression Aof the .transaction .totalizer key releases the r`clutch inamanner similar to that just explained in reference to the-lowering'of lever I49,so-that there is no necessity -for :depressing a special motor bar- The details lof thi-s -releasernechanism, however, do not-form a partcf fthe present invention, so they arenot shown.
During such operations it is, of course, necessary to depress the key stem'24 to select thep'lus or 4minus side of the balance totalizer, so special means has been vprovided toperformfthis function. Referring to 12, a disc .21a-is secured toshaft 21 v,andinas a shoulder 219 .resting-against a roller 280 en the lowerend .of an Y.arm .128i secured ,to shaft 2.69. This lshaft 21 receives one clockwise revolution each operation .of the ,machine andtherefore depresses key stem 24 .at'the beginning of such Operation. "Ihe `disc 1218 cut away at 282 to prevent interference-of roller 28B `.with ,the periphery of 4the disc when the balancelever |49 is operated.
