13 Claims.

This invention relates to computing, bookkeeping and like machines and more particularly to novel tabulating mechanism therefor.

The invention, in the illustrative form herein described and shown is applied to the wellknown Sundstrand machine as disclosed -for example, in Patent No. 1,852,742 issued April 5, 1932 upon an invention of O. J. Sundstrand and application Serial No. 278,950 led May 19, 1928 (now Patent No. 1,901,135, dated March 14, 1933), likewise disclosing an invention of said Sundstrand; although it will be understood to be equally applicable to other types of machines adapted to'perform the same or similar functions.

It is an object of the invention to provide improved tabulating mechanism for machines of the class described. Y

Other objects and advantages will become apparent from the following description.

nTo the above and other ends the inventionv consists of certain features of construction and combinations and arrangements of parts all of which will be fully set forth herein and particularly pointed out in the claims.

In the accompanying drawings,

Figure 1 is a sectional elevation, showing part of a train that may be operated by a columnstop.

Figure 2 is a sectional elevation, from front to rear, of a Sundstrand machine provided with the present improvements. y

Figures 3, 4, and 5 show certain steps in a tabulating operation looking from the front of the machine. In Figure 3 a `column-stop is about to engage the tabulating cam to be-depressed thereby, so as to be projected into the path of a counter-stop.` At Figure 3 the carriage-holding dog is shown released.F At Figure 4 the carriage is shown arrested by the1 engagement of the projected column-stop with the counter-stop, and the carriage-dog is shown restored to Aposition for arresting the carriage when the latter reaches' the proper point.

. Figure 5 shows the column-stop asv having passed the tabulating cam, and also shows the' dog arresting the carriage.' The counter-stop may beieither movablef as shown in Figures 3 kto 5, or lfined. .If desired, the'movable device atV Figures 1, 3, 4, and 5 may consist of a jack to operate a subtraction-controlling train, or any other train. Such jacks are all movable in the Sundstrand machine, but in the present invention the counter-stop does not'need to be moved. ii not connected to a $undstrand Figure 6 is a sectional rear elevation, illus- Ltrating the carriage-returning train in effective position, and showing means whereby the power-drive is controlled.

Figure '7 is a sectional'side elevation, showing` the operation of the carriage-returning key, by which is controlled the return of the carriage from the last check-column to the rst checkcolumn.

Figure 8 is a sectional plan of the improved carriage, with parts broken away to show the invention more clearly.

- Figure 9 is a perspective rear'view, showing generally the digit-keys, the tabulating keys, the various trains controlled thereby, and'also showing some parts that are of usual construction iny the Sundstrand machine.

Figures 9a and 9b show a variety of columnstops with dinerent teeth or tappets, to operate l trains that control it.

Figure 11 is a sectional rear view, showing the carriage-returning trains disconnected.

Figure 12 is a sectional side elevation, illustrating the fmanner of tabulating the carriage to the deposit-column.

Figure P13 is a sectional side elevation, ing the operation of a deposit-key, the carriage being-.released but not yet `arrested by its deposit-column-stop.

In the well-known Sundstrand machine, a work-sheet 20 is placed upon a platen 2| to be printed upon by a row of digit-types 22, the sheet having one column for dates, one for old balances, three columns for checks, one for deposits and one for new'balances.4 The platen is mounted upon side bars 23, 24 of a'carriage, which also comprises a transverse horizontal L frame or bar 25, Figure 2, underlying the platen.

show-.-A ad I riage is a r'oll 29, which runs upon a track 3l, 5o

also supported upon the main frame of the machine.

The digit-types 22 are under the control oi digit-keys 3|, Figures 2 and 9, the types being Cil of different denominations, the types lying one under another in each bar 32. The bars normally stand invdepressed positions, but each bar is elevated under control of stop mechanism (not shown), which is operated lby the keys 3| as isfully disclosed in said Sundstrand application Serial No. 278,950. Each bar may rise to the point predetermined by the key. When the bars are in printingfpositions, hammers 33 press back the types that make up a certain transverse row, thus printing the number which has been selected by the operation of the keys 3|. The parts above described are usually built in the Sundstrand machine, which is also provided with a stop carriage (not shown), which moves step by step at the operation of the keys, so as to control the denomination of every digit which is set up in the keyboard.

In said Sundstrand machine, it is the practice to employ tabulator-stops which normally restrain the carriage; the latter being constantly tensioned toward thev left in, Figure 8, by means of its spring 26. One feature of the presentimprovements is the provision of a dog 35, which normally restrains the carriage. This dog-is not a tabulator-stop. The tabulatorstops, according to this invention, are not normal1y. in use. Said normal carriage-holding dog. 35 is pivoted at 36 upon the rear track 36, which includes a confining flange31 that overhangs said carriage-roll 29. This dog 35 is lifted by a spring 38 into mesh with the teeth 'ofa rack 39. The teeth of rack 39 are beveled so as to permit the carriage to be pushed to the right freely, they dog slipping under the teeth, but capable of holding the carriage at anypoint to which it may be set. This is one of the features of the present invention, which renders-the machine adaptable for use for different kinds of worksheets having differentlyspaced columns. For convenience in locating the carriage, and setting the stops, there may be provided a scale 39E upon the carriage, and a pointer 39b upon the machine-frame, Figure 2.

The carriage being normally detained by said dog 35, the tabulator-stops are normally free and cannot interfere with the movement of Vthe carriage in either direction. The carriage may at any time be released from the dog by depressing a finger-piece 40. This key 40 is on the front end of an arm 4|, which'is mounted on the carriage, or is connectedto'a releaseframe consisting of a pair of arms 42 that are rigidly united to the rack 39 and hinged at 43 to the opposite ends 23, 24 of the carriage. When the key 4|) is depressed, the rack 39 is lifted clear of dog 35, and the carriage may slide to the left, and may be arrested at any point upon releasing the finger-piece 46. It will be obvious that a pin 35a limits the counter clockwise movement of dog 35 'as viewed in Figure 9,' so as to prevent the latter from partaking of the upward movement of rack bar 39.

'I'he carriage is also vautomatically releasable from the dog by pressing the dog down, which is done at the herein-described carriage-tabulat- Y ing operations. Y

In place of the control plate, which is designated |6|0 in the Sundstrand Patent 1,756,401, with its stop-pins, etc., permanently riveted thereto, there is employed a pair of racks 44, 45 extending lengthwise of the carriage, and mounted at their ends thereon; and upon these racks is adjustably mounted a column-stop or stop-unit 46, which is marked Old balance at dog 35 and rack 39.

ance column-stop is arrested by means of a nontraveling or stationary counter-stop 41. It will be understood that normally the traveling carriage-stop 46 is at such an elevation that it will clear the stationary counter-stop 41; but the racks 44; 45 are depressible to permit the en- J gagement of said stops. For this purpose, the racks are xed at their ends in a pair of swinging bars 48 that extend rearwardly on the carriage- frame sides 23, 24 from hinge-pintles 49; said end bars 48 and the column- stop racks 44, 45 forming an up-and-down swingable frame which is normally lifted by springs 53 against stops 5| provided upon the carriage.

While the carriage is being advanced Iby its spring 26 from its extreme right-hand limit, al

beveled shoulderkor cam 52 (Figs. 3 and 8) upon stop v46 encounters the under side of a stationary (non-traveling) cam, said under side or face being beveled at 54, Figures 2 and 7. Said under face inclines leftwardly and downwardly, so that as the stop-shoulder 52 advances, it is forced down by cam 54y together with the stopunit 46, as well as the bars 44, 45 and the arms 48; thus depressing the stop 46 sufficiently to engage the stationary counter-stop 41 and arrest the carriage in position for computing and printing,in the irst column, marked Old balance.

It is noted parenthetically that the columnstop 46 forms one of a set of column-stops, said set including stops for arresting the carriage for printing in the three check-columns of the work-sheet, and also including a deposit l I 'stop 56 and a new-balance stop 51. These stops stop 41 and arrest the carriage in computing and printing positions. At Figure 8 the rst check-column stop 55 is shown in position for arresting the carriage at the proper location for the types 22 to print in the first check-column. 'I'hese stops 46, 55, 56 and 51 may be independently adjustablev along the racks 44, 45, to correspond with any (desired arrangement of columns upon the work-sheet. 'Ihe number of possible positions of the carriageis determined by the rack-teeth 39 in cooperation with normal holding dog 35; and the `lspacing of the teeth in the racks 44, 45 agrees with the pitch of the teeth 39. The dog 35 can be utilized to hold the carriage at any point `for which any stop is adjusted.

Each of the' stops has a carriage arresting tooth 58 to engage the stationary counter-stop 41. It will be understood, however, that inasmuch as the column-stops and racks are normally elevated, they normally escape said counter-stop 41, and normally the carriage is' only held by the It will be seen that the carriage is detained alternately by dog 35 and counter-stop 41.

, Considering now that the carriage has been arrested byl engagement of column-stop tooth 58 with the counter-stop. 41, it will be kept in mind that the carriage must remain here during the manipulation of the keyboard 3l and subsequent printing operation of the types 22. The spring 26 tensions the carriage towards the left, and they cam 54 holds down" the columnstop with its tooth 58 in engagement with the stop 41. At the same time that the column` stop tooth.58l engages the counter-stop 41, it also sets the carriage-holding dog in front of the succeeding tooth on the carriage-rack 39, preparatory to assuming control of the carriage after the machine has been cycled. During such cycling, the column-stop tooth 58' is released from the counter-stop 41, and this permits the carriage-propelling spring 26 to draw? the carriage along a short distance idly until` the next tooth of the carriage-rack 39 advances 'into engagement with the previouslysetfdog 35.

As is usual in the Sundstrand machine, after the digit keys have set the type-bar-controlling devices in the various denominations, an electric circuit is closed by motor-key 59, to cause an operating motor 60 to cycle. The motor causes the number to be run into the computing wheels (not shown), and also causes the type-carrying bars 32 to be elevated -in position lto print the number. During the cycling of the motor, there is operated a set of type-hammers 33, to thrust the selected printing types 22 against the worksheet 26. At a subsequent point in the cycle, the type-carriers 32 drop to normal positions. The Sundstrand motor is self-stopping at the conclusion of its cycle; and the motor-circuit is automatically opened.

During the cycling of the motor, the carriage remains Vunder the control of the vtabulating mechanism, the dog 35 and rack 39 being'temporarily out of use. 'Near the conclusion of the cycle thestop-depressing cam 54 isfautomatically moved out ofthe path of the columnstops, this motion being effected by the general operator.

It may be explained that in the Sundstrand machine, the motor 60 reciprocates the general operator, which is represented by alever 14 (Fig. v2) pivoted at 15 upon the framework, and rocking rst rearwardly and then forwardly. Upon-this lever there is fixed a novel pin 16, which idly passes a pawl 11 during the front stroke of the main rock shaft (not shown) of the machine (i. e., the clockwise movement of the lever 14"). Upon the return or counterclockwise stroke ofthe latter, said pin 16 engages said pawl 11 and lifts'arm 61, thereby swinging rearwardly arm 66 of the bell-crank. The ann 66 carries a pivoted pawl 18, that engages and rocks an arm 19 of a latch 86, to depress said latch and release it from a catch 8| that is provided upon the front end of link 13. Such release permits spring 82 to pull forward said link 13, together with arm 12, which is pivoted at 18 upon a fixture 1t and carries .arm u69, the latter having thereon the cam 54.

The latter is swung back by the spring 82 to its normal idle position, clear of all columnstops, asat Figures 2, '1 and 9.

Springs 58 thereupon liftthe column- stop frame 44, 45,to normal positidn. Since the dog 35 resumes control of the carriage, the columnstop 46 passes out of use, preparatory to bringing a subsequent stop into use.

, 'I'he lever 14", upon completing its return to nor shown in Figure 2 and the pawl 18 is caused to ride to the left as viewed in Figure 2 over the latch arm 19 whereupon it is restored to operative position by the action of a spring 85.

It will be understood that the operation of 5 any `of the column-stop keys may reset said cam 54 forwardly to effective position, and that it will be kept there by the latch 80 that is operated by spring 83.

After an amount has been printed and added in the old-balance column, the machine is ready to handle the amount of the rst check. It is desired to advance the carriage to the first check-column, which, of course, necessitates the release of the carriage from the holding dog 35, and the tabulation of the carriage to therst check-column position. For these purposes, there is depressed a check-key 6l forming part of the novel tabulating mechanism herein disclosed. To enable this key to release the carriage from holding dog 35, the key is mounted upon an arm 62 of a bell-crank, fulcrumed upon a shaft 63, having a pendent arm 64.

The arm 64 strikes movable carriage-releasing stud 65, which is in rear of 64 and is mounted upon the bottom of the arm 66, pivoted loosely upon the shaft 63. The rear end of arm 61 swings up idly for a distance and finally lifts an arm 68 thatds provided upon the carriageholding dog 35, so as Ato swing the arm about its pivot and withdraw the dog 35 from the carriage-rack 39, thereby releasing the carriage and permitting itto be drawn along by means of 'its'spring 26. The dbg 35 is held out by spring latch 81, which catches a flange 81a on the dog.

Before the carriage is released, howevef, pro- Vision is rmade for co-operation of stationary cam 54 with the next column-stop 55, as the carriage tabulates. It willbe remembered that 40 the column-stop frame 44', 45 was swung up by springs when the cam 54 was automatically withdrawn bythe general operator.

Depression of `the check-key 6l not only releases the carriage fromholding dog 35, but also serves to swing forwardly the tabulating cam 54; arm 64 swinging rearwardly and pressing back the pin or stud 14, which projects from the side of the link 13, together with Ime 1mi and arm 12, thereby throwing forwardly cam 54. The spring latch 80 engages teeth 8| on the link 13, and detains the cam 54 in working position. The check-key 6I gives a full stroke to the cam 54, bringing it to position to engage the next column-stop,4 which is 55, as at Figure 8. g55V The cam 54 engagesthe cam-shoulder 52 on the column-stop 55 and forces/the latter down, together with the remaining column-stops and the rack- bars 44, 45; and column-stop 55 engages the stationary counter-stop 41. At the same time the tooth 58 (of which each of the column-stops 46, 55, 56 has one) is made broad enough to engage both the carriage-arresting stop 41 and a jackv 89 formed on latch 81, to depress the latter, thus releasing the dog 35, which is then held up in engagement with rack bar 39 by its spring 38 (preparatory to coming again into service at the ensuing cycling of the general operator). The cam 54 is latched in its effective position, and the carriage spring 26 70, holds column-stop 55 against counter-stop 41. The setting of stop 55 is accomplished by the time the check-key 6| has completed its down stroke. 'Ihe key is released, and it is returned mal pomtion restores the pin 16 to the position to normal position by one of the springs, indi- 15 cated at 86. The keyboard 3| is then manipulated to set up the amount of the first check. Thereupon the motor-key 59 is depressed to reciprocate the general operator as before and withdraw the cam 54, permitting the column-stop frame to rise, and also permitting the dog 35 to resume its control of the carriage.

In order to advance the carriage to the second check-column, said check-key 6| is depressed again, and the carriage is released as before, and it is rearrested by the tabulating cam 54, the second column-stop 55 `and the counter-stop 41; the tooth 58 moving the jack 89 to release the latch 81 that detains the carriage-dog 35, as already explained. Then the amount of the second check is set up, and the motor-key is depressed to cause another cycling of the general operator. The carriage may theri be tabulated to the third check-column by depressing the same key 6|; and the keyboard 3| may be manipulated as before.

It is then desired to tabulate the carriage to` f the deposit column; .and for this purpose there is required a special tabulating key 90, which is incapable of moving the tabulating cam 54 far enough to engage any ofthe short column-stops 46,- 55 (Fig. 8), but only far enough to reach the somewhat longer stop 56. It will be understood that this depositkey 90 could have been used to skip the carriage directly to the deposit column, in case there had been only one or two checks to enter. There is considerable lost motion in the rst part of the stroke of the deposit key 90. Its pendent arm 9| (corresponding with 64) stands at a considerable distance from the pin 14 on link 13. Hence, a large portion of the movement of arm 9| is idle, and the full depression of key 90 will advance said link 13 only a distance equal to two teeth 8|; and then the link is latched by pawl 80. The arm 12 and the cam 54 therefore swing only far enough to reach the path of the column-stop 56,' to engage the cam 52 on the latter. VThe effect is the same as has already been'explained; the cam 54 causing the Acolumn-stop 56 to swing down, together with the column-stop frame, and causing the arrest of the carriage by the counter-stop 41, and also the release of the carriage-dog 35 from the control of its latch 81. The manipulation of the keyboard to set up theamount of the deposit may proceed, and then the general operator may be cycled as before.

It is now desired to tabulate the carriage to the new-balance column; and for this purpose there is employed a tabulating key 92, which sets the tabulating cam 54 'only far enough forward to engage the tabulating stop 51, which is the longest one. The arm 93, which is operated by the key 92, occupies a position considerably forward of arms 9| and 64, as at Figure 2, so that there is much greater lost motion of key 92, and hence the link 13 is finally advanced only to the` extent of one tooth 8|, where it is latched by pawl 80, and the cam 54 swings forwardly only far enough to engage the cam 52 on the longest stop 51. It will be understood that if there had been no checks or deposits to be entered, the carriage could have been skipped at once to the new-balance column, without stepping it through the check and deposit columns. Or, if one, two or three checks had to be entered, and no deposit hadto be made, then the manipulation of the deposit-key could have been omitted, and the carriage could have been skipped by means of the key '92 directly to the operator in the new-balance column, the pin 16 5 operates through 61, 66, 65, 18, 19 to release the link 13, together with the tabulating cam 54, so that the latter is withdrawn by spring 82 from the path of the column-stops, permitting the latter to rise clear of all obstructions, prepara'- tory to the return of the carriage.

The new-balance column being the last on the work-sheet 20, and the line of printing having. therefore been completed, there is no need for the carriage to remainl at the left-hand end of its travel; and preferablyit is returned at once, automatically, preparatory to printing another line. To this end, the tooth 58 is made narrower on the new-balance column-stopl 51, as at Fig. 2 so as not to engage thev jack 89, and hence the carriage-dog 35 remains held out by the spring latch 81. 'I'he carriage-driving spring 26 therefore is permitted to effect a further advance of the carriage, that is, until an adjustable lug 94 (Figs. 8 and 10) thereon strikes the carrage- 2 returning lever 95. This lug 94 fits upon rod 96, which extends from end to endY of the carriage, and is held by adjustable screw 91.

The lever 95 has a latch 98 (Figure l1) which normally holds down a pin 99 upon a spring- 3 elevated swing frame 00. When 95 is moved to the right at Figure 9, the swing frame 00 becomes unlatched and is raised by its spring |0|, which is attached to the end of arm |03 that extends down'from the swing frame. I'he frame 3 swings upon axis |02. The lifting of the frame brings a pinion |04 thereon into mesh with carriage-return rack |05, which extends the length of the carriage, so that when the pinion is revolved the carriage is returned. Fixed to the pinion is a gear |06, with which meshes a pinion |01, which is coaxial with |62. The axis |02 is in the form of a shaft, which also carries a pulley |08, that is driven by a belt |09 and pulley l0 (Figure 2), the latter being mounted on shaft of motor 60.

It will be understood'that at the conclusion of the cycling of the general operator, its circuit was automatically opened, as the motor was no longer needed to drive the general operator. The describedlifting of the swing frame |00, however, has the effect of closing a circuit through the same motor, to cause it to drive the carriagereturning pulley I0, so that the carriage may be returned to the beginning of its run.N It will be understood that the pulley ||0 revolves idly unless the pinion |04 is in mesh with the. rack |05. The carriage-returning swing frame |00 includes contacts |2 and I3, normally open. A spring ||4 tends to move an arm ||5 to close said contacts; but 5 is normally held out of use by means of an arm ||6 that is fixed to the swing frame |00, as at Figure 6. The upward swinging of frame |00 permits the spring ||4 to swing the arm ||5 to the left at Figure 10, thereby 85 closing the motorcircuit ||1, for returning the I carriage.

At the starting of the carriage-returning train, the rack |05 is moved endwise to the left for linespacing, as viewed in 'the rear view, Figure l0,v 70

this movement being independent of the carriage. The rack is mounted in guide openings |8 (Fig. 9) in the end plates 23 and 24 of said carriage, and the play of the rack is limited by stops |20 and |2|. The rack is held in normal position on 75 the carriage by a spring |22 (Fig. 8), but by means of lugs |23 it engages a bell-crank |24, mounted on the carriage, and connected to a forwardly-extending link |25, which has a tooth 5 |26 on its front end, Figure 2, to catch in the notches of a line-space wheel |21 that is provided on the platen 2|. Thus the work-sheet will be line spaced, together with the usual record-sheet upon which all-the entries are manifolded for a succession of work-sheets.

The return motion of the carriage (toward the right as viewed in Fig. 8) continues until an adjustable lug |28, secured upon rod 96 by means of screw |29, encounters a projection |30 upon a gear-disconnecting train, and thereby swings down the frame |00. The projection |30 is pro.- vided upon a horizontal link |3| (Fig. 9) which is pivoted upon a rocker-arm |32. The rocker arm |32 is pivoted at |32* onl the frame member |02, the link |3| has a pin-and-slot connection at |33 and |34 with an arm |35 that rises from the swing frame |00, so that the endwise leftward movement of the link |3| at Figure 10 may' depress frame |00 around pivot |02, thus dropping the pinion |04 from the rack |05, so that the carriage is no longer driven in return direction. The'frame |00 is held depressed by the locking shoulder 98. Inasmuch as rack |05 isv now released, it will be returned to its normal position by spring |22, together with the linespacing train. The Sundstrand` machine is usually provided with stops to limit the possible travel of the carriage in each direction.

By the dropping of the swing frame |00, the arm ||6 is caused to withdraw the circuit-closing arm ||5, thereby opening the circuit ||1, so that the motor may come to rest. The carriage is ytherefore brought under the control of the driving spring 26, which is tensioned to advance the carriage in tabulating direction.

Since it is desired that the carriage, upon being returned, shall resume its `position.for printing in the rst or old-balance column upon the work-sheet, the carriage-returning mechawhile vthe latter is moving in return direction.

The carriage, while returning, overruns to a certain extent,dand passes by the column-stop 46. But the train which disconnects the carriage-returning gears is also effective to `depress column-stop 46 into position to arrest the carriage at the old-balance column. There need not be a stop for positively arresting the return travel of the carriage. It will be seen that the carriage passes by the old-balance column, and

0^will therefore recoil under the impulse of its spring 26, until it reaches said old-balance column-stop 46.

To bring the tabulating mechanism into use,

for the purpose just mentioned, the link |3| is 65 given an idle motion, which is equal to the length of the slot |34, before the end of the slot engages the pin |33 and swings downwardly the frame |00. During this idle motion of the link |3| to the left in Figure 10, arm |32 is swung 70 to the left against `the tension of spring |36.

This arm |32 is part of a lever that has a depending arm |31 formed with a cam |38. At

its lower end, Figures 9 and 10, this cam engages a bevel |39 that is formed on a horizon- 76. tal lever-arm |40, which is pivoted at |40* on nism is provided with means to utilize the herethe frame member |02, said lever extending forwardly at |4| to press forward the arm 69,l which ,swings the tabul ting cam /54 forward to its full extent, so that t is in a position to engage the cam 52 on the rst columnvstop 46. 5

The tabulating cam 54 is latched in this position by the latch 80, and the column stop 46 is provided with tooth 58 to unlatch the dog 35 at the time that the carriage is located in the old balance position by the engagement of tooth 58 10 with stationary counter-stop 41,. y

It will be understood that the dog 35 remains locked against movement into engagement with -rack 39 when the carriage moves into the new balance position because the' tooth 58 on the 15 column stop dening the new balance position is not sufliciently long to contact the arm 89 of the dog latch 81. Hence cycling of the machine in the new balance positionl serves to immediately free, the carriage for leftward move- 20 ment to permit actuationof the carriage return mechanism as a result of which the carriage is restored to its initial or old-balance position in readiness for the printing of a newrline. i

The number of checks to be entered varies, L25 and there sometimes may be many more than three, but they may all be typed inthe three check-columns, by printing the amounts one under another in said columns, before proceeding to the deposit and new-balance columns. 30

After printing three checks in the rst line,

therefore, the carriage may be returned) and the platen may be line-spaced preparatory to entering another check in the iirst check-column. For this purpose, the operator depresses a car- 35 riage-return key |42` (Figure 9), depressing an arm |43 of a bell-crank lever that is pivoted on 63 by the side of the other bell-crank levers, and that has a pendent arm |44, whose office is to operate or trip the aforesaid arm 95, 98, and reo lease the swing-frame |00 of the carriage-returning gear-train. This permits spring |0| to elevate said swing-frame |00, and to carry the carriage-returning pinion |04 into mesh with lthe rack |05, and close the motor-circuit, thereby 45 line-spacing the platen and returning the carriage. The train from the carriage-return key |42 to the releasing arm or lever 95, 98, includes a link |45, which is pressed rearwardly by the arm |44, and operates a bail-form lever |46, 50 in a manner hereinafter explained, to depress a f. link |41; the latter having a pin L|48 (Figure 9) engaging cam |49 formed in the lower end of the lever 9 5, 98, swinging sid lever, and freeing the pin 99 andthe swing-frame |00, for the de- 55 scribed upward swinging movement, to return the carriage. 4

The carriage is desired to come nally to position for printing in the irst check-column; but

in its return movement it overruns that posii tion a little, and at that stage the motoLis disconnected, and its circuit is opened, and the tabulating cam 54 is swung forward a f ull stroke, to enable it to intercept the carriage, as the latter is given a recoil by its spring 26, the

Yinterception of thecarriage being effected by the stop 55 (Figure 8). l

` When the returning carriage is approaching or passing the rst check-column position, as just set forth, it becomes automatically disconnected from the carriage-returning gear-train. This disconnection is accomplished by the aforesaid adjustable lug |28 on the carriage, which strikes. the end of a raised interponent |50, Figure 6,

which is eil'ective in place of D|30, and at an Y earlier movement in the return movement of the carriage. It will be perceived that said interponent |50 was'raised into the path of the carriage-lug |26 bythe operation of the vcarriagereturn key |42. It has already been lpointed out that the carriage-return link |45 operates the bail-lever |46, and pulls down the link |41. This link pulls down the lever-arm I5I, and raises the interponent |50, which forms one arm of said lever.

The carriage-return key |42 does not need to be held down, because the lever |5I is latched up by means of a spring pawl |62, Figure 6. The interponent |50 therefore remains elevated until itis reached by the returning carriage-lug |28,-

' which drives the interponent |50 endwise and carries the link lill on which the interponent is pivoted to the left at Figure 10, until the end of its slot |34 engages the pin |33 on arm |35, and thereby swings down -the swing-frame and releases the carriage-returning pinion |04 from. the rack |05, to stop the return drive of the carriage; the motor-circuit being automatically disconnected by the operation of the arm ||5, as already set forth.

It may be explained that the backward thrust of the link |45, which has a slot-and-pin support at |53, has the effect of camming upwardly an arm |55 (Fig. 2) which forms part of the bail-lever |46, and thereby positioning therear arm of said lever, to which is pivoted at |56 the lower end of link |41. For this purpose a trip-connection is provided between the camming link |45 and'said lever-arm |55, so that at the conclusion of the lever-stroke it may return independently of the link |45. This return is eifected by a spring |51 pulling upon said link |41.

Pivoted upon the lever-arm |55 is trip |58, formed at its front end ,with a cam in the form `of an inclined flange |59 that is engageable by a pin |60 on link |45. ange is held by a spring |6| against the forward end of the arm |55, to afford a support for the trip. The pin |60, as it moves rearwardly in the machine, bears against the under side of ange |59, and presses the same up, thereby swinging the arm and lever. The pin |60 then passes rearwardly under the end of flange |59 of the trip. v'I'he flange |59 projects laterally from the trip, beyond the side of the arm, and it is this projecting part that is engaged by the pin |60. The pin, asit returns forwardly, lifts the trip idly, and passes under it, and then permits the trip to fall, together with the arm and lever, under the tension of spring |51.

At the operation of bail-lever |46, the interponent |50 is lifted thereby, said interponent being latched up by latch |62 (Figure 6), so that the attention of the operator is not needed to hold down the carriage-return key; but the same may be released at once.

The latch |62 normally stands in the position shown in Fig. and is snapped to the left by spring |63, when the interponent |50 rises; the latter remaining latched up by |62 (Figure 6) until the lug |28 on the returning carriage thrusts the interponent |50 to the left from the position in Figure 6 to the position at Figure` 11. Said lug |28 may have a yielding construction,

so that after it hasthrust the interponent |50 and released the carriage from its driving train, there is opportunity given for the carriage to proceed idly a short additional distance by momentum,ibefore a recoil is elfected'by its spring 26. The lug |28 is mounted upon a block |64,

being pivoted thereto at |65, and normally f column-stop when any of the tabulator-keys urged to the right at Figure 8 by means of a strong spring |66, that holds the lug |28 normally against a stop |61 provided upon the adjustable block or guide |64.

At the recoil of the carriage thatis effected by driving spring 26, the lug |28 is caused by its spring |66 to rotate and resume its normal position upon block |64. Then the interponent |50 is swung down by its returning spring |68 (Figs. 9 and 10), until said interponent drops to the left of the latch |62. The interponent carries the latch to the right until it reaches normal position, Figure 10, against the tension of spring |63. l

Thus' an additional check may be entered in the first check-column, and additional checks also in the second and third check-columns; and, if desired, the carriage may again be returned to the rst check-column, for entering still more checks, in the manner just described.l After all the checks have been entered, the carriage may be tabulated to the deposit column,

y or to the new-balance column.

If, at any early stage, the carriage is tabulated to a check-column, and it is found not necessary to enter any amount in said column, the motor-key 59 may be depressed and the general operator cycled, thus withdrawing the tabulating cam 54, whereupon the carriage may be tabulated to the desired column by means of anyA of the selecting keys 6|, 90, 92 (Fig. 9).

However, the necessity Vmay be avoided of cycling the general operator under such circumstances, as provision is made whereby any of said keys 6|, 90, 92 may cause withdrawal of the tabulating cam 54. Any key can operate the stud 65, which, by means of i spring-pawl 18, releases the latch 19, 80, and the spring 62 pulls the link 13 forwardly, and swings the tabulating cam 54 rearwardly, permitting the column-stops to rise clear of the carriage.

Although the carriage is thus freed of the tabulating stops, it still remains under the control of the detaining dog 35, which is held up by its spring 38, and hence cannot jump until'the selected key is depressed enough farther to take up the lost motion between the arm 69 and the dog-arm 68. The key, therefore, does not release thek dog until the very last part of the key-stroke. While the arm61 is moving up towards dog-arm 68, the pendent arm 64, 9| or 50 93 is pressing rearwardly the cross-pin 14 on link 13, and hence swinging the cam 54 forward to the desired extent. The cam therefore f reaches carriage-controlling position just as soon as the pawl or dog releases the carriage. 55',

In order to guard against accident in the operation just described, a pallet |69 may be pivoted at its right-hand end upon a xture (Figure 9) in position to intercept the approaching y are depressed. The pallet has an arm |10, `connected by a spring |1| to arm 61. This spring tends to lift the pallet into the y path of the, column-stop, so that if the dog 35 should release the rack too soon, the column-stop and carriage will be detained by the pallet. The pallet is withdrawn by means of a finger |12 uponthe rear end of arm 61, which engages a shoulder |13 upon the pallet- The pallet 69 rises into the path of a. projection |14 upon that 70J 'column-stop by which-it is intended that the carriage shall eventually be arrested at this operation. The pallet |69 is thereforeeiective regardless of the position to which the columnstop has been adjusted upon its racks. ,Eachof the` column-stops, except 51, is providedewith this projection |14 (Figure 9).

i the controls 88,' |11.

Each column-stop may consist of parallel blades fixed upon spacer-blocks |15, so that the blades may enter adjacent notches in the racks. -In the standard Sundstrand machine are provided various jacks or slides |16 (Figs. 1 and 2), forming a rearwardly-extending row,V these jacks taking part in the various functions of the machine, such, for example, as non-printing, subtracting, non-adding. selective register-control, and multiplication by repeated addition. Any one or more of these jacks may be operated by the described colunm-stops, by simply forming the main blade thereof with one or more -teeth 88; |11 in addition t0 58,-teth 88, |11 beingproperly located to engage any desired jack or jacks ina set; these teeth taking the'place of the arrays of studs which are fixed in the swinging control plate in said Sundstrand patent, and being adapted to control allthe jacks selectively, thereby 'conditioning the machine in various ways at the arrest of the carriage in its several column-positions. The adjustability of the column-stops presents an advantage over said xed Sundstrand studs, because the machine operations may be made to take place at various points selectively in thetravel of the carriage, by merely readjusting the column-stops having An assortment of lcolumnstops may be kept on hand by ther'owner of the machine, from which he may select a variety .of stops with the desired controls 88, |11 for any kind of work, so that the services of a machinist are rendered unnecessary in conditioning the machine for a new kind of work.

It will be evident from the above description that any one .of the column selecting keys, that is, the several check keys, the deposit key or new-balance key may be operated to diieren- Ltially move the link 13 and thereby selectively position the cam 54 for cooperation with the column stop identified with that column in which it is desired to arrest the movement of the carriage. It will likewise be apparent that whereas the ratchet teeth of the bar 39 are positioned somewhatV to the right of the respective positions in which the carriage is brought to rest to dene columnar spacing, that this is solely a matter of mechanical adjustment to prevent the possibility of `dog 35` engaging the downwardly projecting ends of any of the teeth of the rack bar and thus possibly permitting the carriage to move an appreciable amount after being released by the column stop.

Variations may be resorted to within the scope of the invention, and portions of the improvementsmavbe used without others.
