6 Claims. 1

This invention relates to accounting machines having two or more registers and more particularly to an improved mechanism for selecting the said registers for operation, and for printing signals identifying the selected registers.

In accounting practice, it isoften desirable to accumulate amounts entered in the machine keyboard in both registers, print totals of one of said registers vat the completion of each posting operation, land print a grand total from the other regi-ster after completing a series of postings over a predetermined period of time.

It is, accordingly, one of the objects of the present invention to provide a mechanism for automatically selecting one or the other of the registers for operation in certain columnar positions on a work sheet, and for selecting them for operation jointly in other columnar positions thereon.

Another object of the invention is to provide.

means for manually selecting the registers for operation individually or jointly.

Still another object of the invention is to provide means operable under the lcontrol of the manual register selecting means for enabling the printing of signals identifying the register or registers selected thereby.

A further object 4of the present invention is to provide means for automatically and manually selecting the registers wherein elements common to both means, upon being actuated -by either means, selects the registers without interference with, or detriment to the other means.

A still further object of the present invention is to provide a combined automatic and manual register selecting means which is simple in construction, economical to manufacture and assemble, and which is dependable in operation.

With these and incidental objects in View, the invention consists in ycertain novel features Aof construction and combinations of parts, the important elements of which are set forth herein in a preferred embodiment hereinafter described with reference to the drawings accompanying and forming part of this description.

In the drawings:

Figure 1 is a right side elevation of the machine showing the parts in normal position,

Figure 2 is a right side elevation showing the manual register selecting slide,

Figure 3 is a left side view showing the register selecting structure in position to select the Vupper register,

Figure 4 is a plan view` showing a part 0f the register selection mechanism in position to select both the upper and lower registers,

Figure 5 is a view simil-ar to Figure 4 but showing the mechanism in position to select the lower register,

Figure 6 is a perspective view showing a part of the register selecting structure.

The invention is herein exemplified in a machine similar in character to the one disclosed in Patents No. 1,946,505 and 1,946,823, to Oscar J. Sundstrand, dated February 13, 1934, and in Patent No. 2,251,100 to W. A. Anderson, dated July 29, 1941, to which reference may be had for an understanding of features not fully illustrated or described herein.

General description In general, the machine includes, in part, a keyboard comprising amount setting keys, a motor key for controlling operation of the machine by an electric motor, and function controlling keys. Also included in the machine are -controls for `automatically conditioning the machine for performing lits various functions. A traveling paper Icarriage is provided to carry a cylindrical platen for supporting a work piece and to carry control elements for actuating automatic controls in the various columnar positions of said carriage. The machine includes two registers, each of which is usable to add and subtract, and is provided with means for automatically introducing the .fugitive unit which means automatically conditions the machine for the taking of a credit balance or negative total, and type bars operating under the control of the said amount setting keys or the said registers for printing entered amounts and totals of the registers respectively on the work sheet.

Detailed descrip-tion Referring to Figure 1 of the drawings, the machine includes ia plurality of type bars 2d which `carry type 25 and are supported for vertical reciprocatory movement on a bar 22 and a slotted bar 23 for printing on a work piece supported on a cylindrical platen 26 mounted in a traveling paper carriage l(not shown). The machine is operated by a motor (not shown) which is suitably Iconnected to a main shaft 30, Figures l and 3, carrying an arm 3l, to `rock the shaft 30 clockwise, from its normal position, as seen in Figure 3, and return it to complete a machine cycle. A link 32 connects the yarm 3l and a lever 33' pivoted on the machine frame at 34, vand on the other side of the machinea link 35,Figur e 1,connects a lever 36, pivoted `at 31, on the machine frame to an arm 38 aflixed on the main shaft 30. Upon rocking the shaft 30 clockwise, Figure 3, the mem-l 41 for addition and lie for subtraction. .means provided for such movements include, genwardly ber 53 through a llnk 83 and |33,

enligne bers 33 and 3S are rocked counterclockwise about their pivots 34 and 31 to act upon levers 4| and raise the type bars to their various type printing positions, and upon the return of the main shaft 33 to its normal position, to restore type bars 24 to their normal positions by means of a bar 44, in the manner disclosed in Vthe Patent 1,946,505 referred to. l

Each of the numeral type bars 24 carry racks 43 and 41, slidably supported on studs 48 therein,

and normally tensioned downwardly by means iv springs 49 to enable tens transfers and the introduction of the fugitive one in the conventional manner. A pair of registers 51 and 53 are mounted between said racks 45 and 41 on shafts 53 an 54.

Thejl register wheels are arranged so that the wheels 51 are moved into mesh with the racks 45 for addition and 41 for wheels 53 are moved into mesh with the raclks erally, a composite slide member 8 I, Figure 1, supn ported on hangers 52 and 63 which are pivoted on the machine frame, slide 3| being moved leftand rightwardly by means of a cam mem- 53 by means of the pawl 33 secured to arm 38.

Ai'TiXed in the composite slide member 6| are studs 55 and |51 on which are slidably supported levers 38 and 39 for shifting the upper and lower register wheels 51 and 53, respectively, intoinesh with their associated racks IS and lll. The llevers 33 and 3Q are connected by means of a link 13 and are normally urged leftwardly in Figure 1 to hold the register wheels 51 and 58 out of mesh with the racks 46 and 41 by means of a common spring 1I, connecting the link 1|) and the composite slide member 5 l. The levers G8 and B9 vare each provided with two L-shaped apertures 15, engaging pins 11, in plates 19 and 85 secured to shafts 8| and 82 respectively. `Secured to the opposite end of the shafts 8| and 82'are plates Figure 3, which plates are connected with the register wheel shafts 53 and 53 by means of links 55 and 83. In the drawings the levers 63 and 33 are positioned for engagementA with the lower pins 11 to enmesh the register wheels i 51 and/or 53 for addition. The levers may be moved to engagement with the upperv pins 11 to mesh the register wheels and racks for subtraction and credit balances in the manner disclosed in the above patents. Meshing of the wheels 51 and 5S and the racks 43 and 31 is obtained by either automatically or manually selecting keither' or both of the levers 58 and 69 for moverriei'itbyl means of the studs 66 and S1, and thereafter moving the composite slide member 6I rightwardly to the position shown in the drawings by means of the cam member 59 and arm 38.

Automatic selection of the upperregz'lster Referring to Figures 1, 4, 5 and 6, the machine is provided with a plurality of control members 93 supported for slidable movement on studs 83 in a control box 9| afxed to the machine frame.

A sliding member 92, carrying a pin 93 engaging i a slot in the control member 9D, is slidably supported for movement laterally on the machine in brackets 95 affixed to the machine frame, and is normally tensioned leftwardly, as seen in Figures 4' and 5, by a spring 35. Mounted loosely on the pivot 34 and extending rearwardly into the path of movement of the sliding member 92 is an arm 93, provided with a rear tongue 99 supported for slidable movement'in a bracket |00 firmly secured 4 to the machine base, said arm 33 being also 'pi' vided with a formed lug lili. A spring H3 connected between arm 33 and bracket 35 tensions arm 98 into its leftmost position as shown in Figure 6 against the end of slide 32. Arm 98 may be moved rightwardly into two additional positions by .a lug |33, Figures l, l and 5, Vmounted ina plate IBI, Figure l, attached to the traveling carriage. If pin IE5 is in line with other pins in the plate |6I, particularly the pin used to arrest the carriage in a columnar position, it

subtraction, while the Y moves slides 93 and 92 and arm 98 to the rightlmost position as shown in Figure 5 but if the pin I Ellis oifset to the left from the other pins, slides and 92 and arm 98 are moved only to a midposition asshown in Figure 4. The selection of .the registers under control of arm 33 in each of `its positions will be described at a later point in this specification.

Referring to Figures 3 and 6, a lever |35 with an ear |06 is pivoted on a shaft 5l] and pivoted thereon, onl a stud |01, is a dog |33 tensioned to normally bear against the ear |05 by means of .a torquespring H3. The stud |31 is provided with two steps for engagement with the member 98 -in its Ytwo leftmost positions, arm 93 in its right hand position being out ofl the path of stud |31, see also Figures e and 5. The lower arm of lever |35, see Figure 3, is provided with a slot I|1 in which loosely rests a pin ||8 aflixed in a slide I i9 supported for vertical movement on the pivot 33, and connected at its lower end toa lever I2I. Pivoted on a stud '|22 in the levei" |65 is a member |23 having a cam edge |24, and an ear |26 normally tensioned to' bear against the bottom of pin I I8 by means of a spring |21 connected between lever |05 and member |23.` Rigid in the lever 33 is a stud |28 arranged to act during a machine cycle upon the dog |38, and a roller |29 arranged to engage the cam edge 24 of the member A|23 to-position lever |35 and slide I I S during each cycle to determine register selection as will be later described.

'Lever I2I is pivoted at |33 on an arm |35 aiiixed on a shaft |36 pivotally supported in the frame and carries va stud |31 normally tensioned to bear against the lower edge of arm |35 by `means of a rspring v|39 between lever |2I and arm |35 to provide a yielding connection of the parts. The arm I 35 is provided with notches onits upper edge. in which is engaged a spring urged detent |44 to retain the parts |35, IIQ, I2| and the register or registers selected in that condition during cycling of the machine.

Afxed to the opposite end of shaft |35, Figure Y i, isan arm |50 carrying a stud |5I. Pivoted on -stud |5I are two arms |52 and |55 each slidable `at its upper end on a stud |53 or |55 on the levers 68' and 63 respectively. The forward edge of each arm rests against the studs 66 or 31 respectively in slide 6| and determines that the vlevers 68 and 69 shall move with slide 5|. The forwardedges of arms |52 and |55 are, however, notched so asv to free the upper lever Glifrom stud 66 when arm |53 is in its clockwise position l and to free lever 53 from stud 61 whenarm |50 is 'in' the counterclockwise position as shown in i Figure 1.. Thus in these two positions only the "lower or upper slides 5S or 59 will be shifted and only one register will be engaged with the racks 46 or 41. In the central position of arm |30, both levers are moved with slide 3| and consequently `both registers -will be engagedY with racks 46 .-.and 41.

Selection ofthe Vregisters is controlled by the movement of control member 90 from the normal Figure 6 Vposition to one of the two positions shown in Figures 4 and 5 by means of pins |60 xed in the control plate |6| supported in the traveling paper carriage (not shown), in rows as above set out. Selection of the upper register Wheels 51 only is the normal operation of the machine when no pin |60 is effective. Therefore the parts normally remain in the position illustrated in Figures l, 3 and 6. Accordingly in any columnar position in which a pin |60 is omitted from the control plate |6|, the position of the control member 90 is unaffected so long as the carriage rests in that columnar position, and arm 98 is tensioned to the left toward the'Figure 6 position. During an ensuing machine cycle and after slide 6| has disengaged the registers, the stud |28 in the lever 33 strikes the face of dog |08 to rock lever |05 counterclockwise, Figure 3, enabling arm 98 to move in front of the higher stop face of stud |01 if it is not already there, and raising slide ||9 and lever |2| to the Figure 3 position. Roller |29 then strikes the cam edge |24 of lever |23 and rocks it clockwise but as member is restrained from moving by means of the engagement of stud |01 with arm 98, such movement of lever |23 is ineffective to return lever |05 clockwise and lever |23 returns to its Figure 3 position when roller |29 moves away from the face |24 of member |23 during the second part of the machine cycle.

Movement of slide 9 to its upper position at such time, determines selection of the upper register during the next part of the machine cycle. Raising of slide |9 through lever |2| and shaft |36 lowers the arm |50, Figure l, to put the notch in arm |55 in back of stud 61 so that subsequent movement of slide 6| to the rear will not cause register 58 to be engaged with the racks 41 or 48, only the upper register 51 engaging the racks. Detent |44 acts to retain shaft |36 and arms |52 and |55 in their adjusted positions during the latter half of the machine cycle.

Automatic selection of both registers Should it be desirable to select both sets of register wheels 51 and 58 for simultaneous operation, a pin |60 is inserted in control plate |6| but is offset from the line of the other pins as shown in Figure 4. Such pin |60 when effective moves, through slide 92, arm 98 into the Figure 4 position in alignment with a lower stop face on stud |01. Now during an ensuing machine cycle, stud |28 strikes dog |08 to rock arm |05 to its counterclockwise position as described above. Immediately thereafter roller |29 engages the cam face |24 of lever |23 and rocks the lever |23 clockwise. Lever |05 will follow the motion of lever |23 until stud |01 strikes with its lower stop face on tongue |0| of arm 98 and stops the lever |05.

Slide ||9, lever |2|, shaft |36 and arms |50, |52 and |55 are thus moved into a central position. In such position, neither arm |52 nor |55 has its notch in alignment with a stud 6601' 61 and hence both levers 68 and 69 follow the subsequent movements of slide 6 to engage both the upper and the lower register wheels 51 and 58 with the racks 46 and 41.

Automatic selection of the Zofwer register only When it is desired to select only the lower register 58 for any columnar position on a work sheet, pin |60for that column is placed in line with the other pins for that lcolumn in plate |6|.

Such a pin when it engages slidev moves the slides 90 and 92 and arm 98 to their extreme right hand position as shown in Figure 5. When arm 98'is in such position it is clear of stud |01 and hence when lever 05 is urged clockwise by roller |29 acting through lever |23, there is nothing to stop arm |05 until it reaches its clockwise limit. This movement of lever |05 depresses slide ||9 to rock shaft |36 and raise arms |50, |52 and |54 to their upper positions. In such position, the engaging mechanism for register 51 is ineffective since .the notch in arm |52 is aligned with stud 66 and only the register 58 Will be engaged during the remainder of the machine cycle.

It should be noted that stud |28 on its return stroke rocks dog |08 idly about its pivot stud |01 and hence does not alter the position of slide |9 and lever |05. It should also be noted that lever 05 is restored to its counterclockwise position near the start of each cycle and arm 98 at this time is free to be moved to the left into a new position if such is required by the automatic carriage controls.

Manual selection of the registers In accounting practice, it is frequently desirable to make a manual selection of the registers. In the interests of economy of manufacture, ease of assembly and dependability of operation, the present invention provides a single train of mechanism for automatically or manually selecting the registers. For such manual selection, a register selection slide |61, Figure 2, is slidably supported on studs |66 and has a slot |68 vembracing a pin |69 fixed in a leg of a cradle |1| pivoted on a stationary shaft |12. Pivoted on a stud |14, Figure l, in a second leg of the cradle |1| is a link |16 connected by a stud |80 to a member |8|. The member |8| is fixed to a member |82 and both of these members are pivotally supported on a stud shaft |83. A link |84, pivoted on the member |82, is connected to an arm |86, Figure 6, secured to an upstanding shaft |81 journaled in the machine base. Mounted on the shaft |81 is a selector |88 engaging a pin |90 in a lever 9|, pivot'ed on a stud |92 and forming part. of the credit balance control mechanism as shown in the above patents. Pivoted on a screw on .the machine frame is a lever |91 bifurcated to embrace the pin |9|!y in the lever .|9|, and extending upwardly to bear against a pin |99, in the sliding member 92. A spring 200 between lever |91 and slide 92 serves to hold the lever |91 against stud |99.

The register selector slide |61 is arranged for movement to three positions corresponding to the three carriage controlled register selections. Accordingly, with the slide |61 in its extreme forward position, the parts are in the positions shown in Figure 1 in which position the stop portion |0| of the member 98 is aligned with the higher stop face of stud |01, to condition the machine for normallyselecting the upper register wheels 51 for engagement with the racks 46 or 41.

Upon movement of the totalizer selector slide I 61 to its central position, the cradle |1| is'rocked by means of the pin |69, moving the link |16 rearwardly. With this movement of the link I 16, the members |8| and |82 are rocked about their common pivot |83, whereupon the link |84, Ythrough the arm |86 rotates the shaft |81, Figure 6, in the machine base, and the selector |88, actingv upon the p in |90, rocks the member |9| about its pivot |92. The bifurcated lever |91l wardly, to position the Vmember 98 in alignment with the lower V21W hooking over a tail on the hammer.

.germes engaging the pin |90, is thereby rocked about its pivot |95, whereupon its upper arm, bearing against the pin |89, moves the member 92 rightstop portion lIEM .of the stop of the stud |81, and to thereby control engagement 0i both the upper and lower register wheels 51 and 58 with the racks t6 and 41 for addition or subtraction during cycling of the machine in the same manner as previously described for the automatic selection of the registers.

Likewise, movement of the register selector slide |61 to its rearward position rocks the cradle l1| to its rearmost position, moving the member |16 rearwardly and the slide 92 rightwardly to position the stop portion Il of the Amember 98 clear of the stud E81, and thus to condition the machine for selection oi the lower register wheels 58 only for addition, subtraction or totaling in the manner previously described.

A detent arm 261 provided with notches is mounted on a bracket 229 on the machine frame and is tensioned downwardly by a spring 2|2 to engage a pin 2li on the link |16 in one of the notches and thus hold link |16 in any set posi- 1 tion. y

Manual signal control In machines of the class described, it is customary to print symbols adjacent the printed amounts to indicate the operation performed during that cycle. In the present machine it is desirable to print such symbols only when the slide |51 is set toV alter the normal machine ccndition. A symbol type bar hammer 232| similar to the other type bar hammers is driven by a spring 238 to print from the associated symbol type bar 22 but is normally restrained by a latch This latch is released by an arm 222 pivoted on a printing release bar 2:33, bar 243 moving arm 2&2 rearwardly about the middle of each cycle. Arm 242 is normally held by a spring 264 in a position clear oi latch 245i to preventr symbol printing.

However, if slide li is moved into either its central or rearmost position, right in Figure 2, the symbol type hammer release arm 242 is thereby rendered active to enable symbol printing.

`As seen in Figure l, stud |18 in cradle |1I will,

as the cradle Eli is swung clockwise, cam upwardly the end 253 of an arm of a lever 248. The rear arm of this lever 248 rests on a projection of the latch release arm 242 and swings upwardly the rear end ofthe arm 242 into en- A gagement with latch 25.8 whenever slide |61 is in either its central or rear position thus enabling ,symbol printing when the normal register selection is altered. v

The symbol type hammer is also released by depression of the subtraction key to print the subtraction symbol. The subtraction key 22|, Figure 2, has a stud 218 thereon, the stud 214,

see also Figure 1, normally positioned above an arm 213 pivoted on shaft 215 and resting on an 'ear 215 of lever 228 to rock lever 248 upon depression oi the subtraction key 22|. The symbol type bar 2li is adjusted to present the proper symbol to the platen 26 by mechanism forming no part of this invention and substantially as kshown in the above patents. f v

The machine is also provided with an interlock to prevent shifting of slide |61 to a new position during a machine cycle. 'As shownpin Fig- Y`ure 2, the. motor bar-283- operates througha spring 284 toidepress a slide 285.- This slide 285 is corinected to a cycle trip wire to initiate a machine cycle in the usualv manner and also to rockr a cradle 292 pivoted on a shaft 293. The cradle has alateral ear which is engageable with two ears 296 on link |16 which it will be remembered is directly connected to slide |61. Such engagement will prevent a change imposition of slide |51 during a machine cycle or alternately will prevent initiation of .a machine cycle if the slide |61 is between two of its positions. The subtraction key 22|, Figure 2, has a lower extension 281 engageable with a stud 289 on motor bar 283 to depress the motor bar with the subtraction key and so latch link |16 during subtraction cycles.

A further feature is a provision to prevent a total-taking operation of the machine while lever |61 is in la position to select both registers. As shown in Figure 1, in the central position of slide |61, stud |14 of cradle |1| depresses an arm of a lever 388 pivoted on shaft 255. The lower arm of lever 300 is connected to a pair of spring connected links which extend to the rear'and in front of a hinge plate 3|2. This hinge plate is standard in this type of machine and is moved forwardly by power in a blank cycle to prepare for a total taking cycle. So long, however, as slide 961 is in its central position, links (-325y and 305 maintain a pressure on plate 3|2 and thereby restore it to its rearward position as soon as the plate is released from its power setting means, thus preventing taking of a total on the next machine cycle.

The above description is of a preferred embodiment of my invention and is not to be taken in a limiting sense as many variations in structure are possible without changing the mode of operation of the structure, all Vcoming within the scope of the appended claims.
