l. Themcth'oll of finishing the contact eleframe 1, mounted to travel longitudinally of a flat platen, not illustrated, and having front and rear carriage guides 2 and 3, which slidably support a carriage 4, movable transversely of the platen and supporting the, printing mechanism. The upper portion of the carriage "I is in the form of a casing 5, within which are mounted the key levers, having connection with the keys disposed above the casing, and do\vnwardly-striking type-bars, located below the casing, as is well understood in the art. The carriage 4 is drawn to the right by carriage tapes 6, and its st'ep-by-step advance in the direc tion of letter spacing is permitted by the operation ot-carriage-feeding mechanism 7, including-pivoted feed yokes 7", one at least of which is moved to operatethe carriage escapement when-any one of the several keysis completely depressed, The carriagefeeding mechanism 7 is indicated in Figure 4 of the drawings, and thepurpose of calling attention to it in connection with the present'invention is to emphasize the, fact that machines of the class under discussion include a traveling carriage which supports the printing mechanism and which is ad vanced step-hy-step the distance of one letter spacewhenever one of the keys is compltely depressed.
ln carrying out my invention, I mount in rear of'theimachine frame 1 a guide bar 8, supported-in parallelism with the frame by a pair of'brac-kets 9, bolted or otherwise rigidly secured to the re'ar carriage guide 3 andextendedupwardly to dispose the bar 8 substantially in the'horizontal plane of the top 'of the casing 5. Upon this guide bar, which is disposed parallel with the lines of "Writing, are adjustably mounted a pluralit-y 0t compnting'devices, which in the presentemloodiment of the invention may be designated column 'totalizers 10 and 11, and an additional computing device which may be 'termed a gr'and'totalizer 12. The column totalizers, of which any desired number may be employed. are; designed to'compute the totals ofindividual columns of figures, opposite which the have been located by their adjustment upon the bar 8. The grand totalizer 12 is designed to compute the grand totaloi the several columns. and is preferably mounted upon an extended end of the bar 8 to dispose it beyond one Side of the printing area of the platen.
The computing and registering mechanism. within the casing lfl'of each totalizer. will be hereafter described in detail. For theprcsent, however. it is sulhcient to call attention to the fact that this mechanism comprchends. is usual in this class of devices, a series of denominational members. digit carriers or number Wheels 1. c. d. e. f. 2. ii. and I designed to register hundredths, tenths. units, t ns, hundreds, them sands, ten thousands, hundred thousands and millions, the tenths and units wheels I) and a being spaced apart sufliciently to provide an intermediate decimal space. Each of these Wheels is provided upon its periphery with the digits, 9 to 0 inclusive, preferably formed in or upon the end-faces of peripheral teeth, one digit of each wheel being observable through a sight opening 14 in the downwardly-curved front end of the top Wall 15 of the register casing. Each of the number wheels isarranged 'to make nine-tenths of a complete revolution :independently of the other wheels of the series, to present its digits successively before the sight opening, and during its last increment of movement engages the adjacent wheel at the left and rotatesit a single increment or step, after which the first-named wheel may again rotate independently for nine-tenths of a complete rotation' before again advancing the adjacent wheel at the left a single step.
Since the wheels of the entire series are related to one another intheunanner stated, it follows that mechanical computations-in addition may be effected by moving the wheels, corresponding in orderito the order of the numeralscomposi the numbers to be added, a number of increments: corresponding to'the unitary values of such numerals. Thus, suppose it isdesired to add 432 and 234, theciphers 'ofall of the wheels being disposed opposite thesight: opening 14. The wheelof the third order, to-wiathe wheel e, will berotated four incrementsppre' senting the numeral-"tat the sight opening; the wheel at of=the second order will be rotated three increments and, the'viheel, cof the first order two increments or steps. The numerals exposed'be'fore thesight opening will now read 432,:corresponding to the first number. The second number-flil'willi now be added by-impartingto the third order Wheel e two additional increments of movement, to the second order wheel 0? three increments and to the first order wheel a four increments, thus causing the numerals presented before thesightopeningito read 666, the sum of the twonumbers;
Since the numerical value of'each order is 10, and since each wheel during its last increment of movement will, as heretofore explained, impart a single incrementof movement to the next adjacent wheel to-the left,
it follows that when the number registered reaches the limit ofthe numerical value of a given order, the rotation of the adjacent wheel will efl'ect the registration of a numeral of the next higher order. Thus, as suming the first order or unit wheel 1: to have been given nine increments of more meat. causing the presentation of the numeral 9 before the sight opening, the next or tenth increment of movement will present the 0' on said wheel before the sight open -mg, and by the automatic engagement of the presentation of the two digits 0 and 1 in the first and second orders effecting the re 'stration of the number 10.
t will of course be understood that the mechanisms within the casings of the col umn totalizers and the grand totalizer are identical in construction, and may be said to constitute the computing or adding mechanism proper which ismounted independently of the carriage. Upon the carriage is mounted another portion of the computing mechanism, to-wit, actuating mechanism presentable in succession to the number wheels ofeach of the column totalizers by 'the step-by-ste advance of the carriage, and
operatively re ated to actuating mechanism for the grand totalizers, presentable to the number wheels thereof in succession as the first-named actuating mechanism traverses any one of the column totalizers, it being understood that these actuators are designed to rotate the number wheels of the totalizers and-grand totalizer in proportion to the numerical values of the numerals embraced by the computations. This arrangement is one ot the novel characteristics of the invention viewed=as a calculating machine, since the :travelingcarriage supporting the operating 'mechanism for the'number wheels is not necessarily :the carriage of la typewriting machine. Itis contemplated, however, to
utilize: key-operated numberwheel actuatorsfand although it 'is notessential that -40 ling devices; the illustrated embodiment of these keys be arranged to operate the printthe inventionr comprehends the utilization of-the numeral keys of a typewriter as the operating means for the actuators. T
Having a general understanding of the arrangement andmode of operation of the totalizers and grand totalizer, we may now consider the arrangement of the actuators for the number wheels, and the mechanism for effecting an operative connection between the actuators and the numeral keys of the typewriter, it being understood that the combined typewriting and computing machine, to be specifically described, is intended to print several columns of numbers, as well as to compute and register the column totals and the grand total of the numbers recorded. It-may be stated at this point that the actuator of the grand totalizer is operatively connected to the actuator for the column totalizers, and that the specific mechanism for operating the last-named actuator from the numeral keys does not con- Stitute part of my invention.- On the contrary, the specific construction of the totalizers, the mounting of an actuator on the traveling carriage for presentation to a totalizer, and the connections between the numeral keys and said actuator, all as shown in the accompanying drawings, are features of the invention of Laganke and Smith, and are fully disclosed in their application aforesaid. It appears to be unnecessary, therefore, to do more than describe in a general way the mechanism connecting the keys with the actuator for the column totaliners, and to then describe with greater particularity the relative arrangement of the grand totali'zer and the means whereby its actuator is operated in synchronism with the actuator of the column totalizers.
Above the key levers 16, which latter are disposed within the casing 5, as is well un derstood in the art, is mounted a swinging yoke 17 (see Figure 4) having a series of graduated contact plates 18, each located directly above a numeral key lever and deeffect the rotation of a number wheel to an extent correspondin to the numerical value printed, and it is or this reason that the plates '18 are graduated, in order that the yoke, which is a motion transmitting element common to the several keys, will be moved a different distance upon the depressionof each key. Upstanding from the bottomof the (3BS1Ilg51 is a plunger guide 19, within which is'm'ountedfor vertical reciprocation a plunger-20, designed to; be operated by the yoke and arranged in-turn to swing a rack lever 21, mounted above the casing-'5, and geared tothe master wheel or actuator 22,015 the column totalizers. At the lower end of theplunger 20' is formed an angular arm 23, disposed'in the the plunger will be raised in an obvious manner and will be dogged by a ivoted dog 25,mounted'onthe plunger i e and disposed to engage a rack 26, firmed in one sideface of the plunger. Upon the complete depression of a key one of the feed yokes will strike the front end of a lever 27, to swing the same for the purpose of causing a release'finger 28 thereon to strike the tail piece of the dog 25, to move the same out of engagement with the rack and thus permit the retraction of the plunger.
Over-running of the master Wheel 22 is prevented by a checking arm 29, connected to the lever 27 by a link 30, and disposed to be swung into engagement with the master wheel as the latter completes its movement. The actuating or rack lever 21 is fulcrumed on a short horizontal shaft 31, sup ported by posts 32, constituting elements of a supporting frame, the base plate 33 of which is bolted or otherwise secured to the top of the casing 5 at the rear side thereof. At the rear end of the lever 21 is formed a segmental rack 34, meshing with a pinion 35, formed upon or rigidly attached to a short horizontal sleeve 36, mounted to rotate upon a shaft 3T, extending between posts 38 upstanding from the rear end of the base plate 33. At the end of the sleeve 36, opposite the pinion 35, is formed'or attached a ratchet wheel or disk 39, the teeth of which are designed t be engaged by a pawl 40, carried by the master wheel 22 and urged toward the ratchet wheel by a s ring 41. The master wheel 22 is mounte upon the shaft 37 beyond one end of the sleeve 36, and is intended to mesh with successive number wheels as the carriage is advanced in the direction of letter spacing. Reverse rotation of the master wheel is prevented, by a pawl 42, preferably mounted upon one of the posts 38 and engaging a ratchet disk 43, fixed to the master wheel and having its teeth disposed oppositely to the teeth of the ratchet wheel 39. i
The depression of one of the numeral or digit keys of the typewriter effects more or less elevation of the yoke and plunger through the swinging of a key lever, and the consequent elevation of the rear end of the rack lever 21, engaged by will depress the segmental rack 34. The depression of the rack will rotate the pinion 35, and the ratchet wheel 39 moving with said pinion will enga e the awl 40 to rotate the master wheel, an there y impart movement to one of the number Wheels, the extent of such movement corresponding of course to the movement imparted to the yoke by the particular key lever actuated.
It has been stated that the actuator of the grand totalizer, which for the purpose of distinguishing it from the actuator 22 may be termed the grand actuator or grand master wheel, is operated from and in synchronism with the master wheel of the column totalizers. It will therefore be ap parent that some means must be provided for disconnecting the latter from the numeral keys while traversing the interval between two columns, or, which is the same thing. between two column totalizers, as otherwise the grand totalizer would be operated upon the depression of the numeral keys to print numerals other than those designed to be embraced within the computation.
Various devices for accomplishing this end might be employed, but by preference a rock-shaft 44 1s journaled in a sleeve bearing -15 at the rear end of the casing 5, and is provided at its opposite ends with a yoke elcvatiug cam 46' and a trip arm 4?. The rain -16 is disposed to enga e the under side of a fixed part of the yo re 17, as, for instance, the horizontal portion of the plunger,
an angular plate 47 secured thereto. Encircling the rock-shaft is a sprin 48, secured at its opposite ends to the sleeve 45 and the cam 46, respectively, and tending constantly to urge the cam in a direction to elevate the yoke 17 for the purpose of' removing the operating connections of the computing device entirely out of the paths of movement of the key levers. The trip arm 47, located at the rear end of the shaft 44, is mounted loosely thereon adjacent to one side face of a head 49, fixed to the shaft and provided with a ledge 50. opposed to one end of the arm 47. This ledge constitutes a stop limiting the movement of the arm 47 relative to the shaft 44, in one direction, but such independent movement of the arm in the opposite direction is per mitted by the rounding of one corner thereof, as indicated at 51. (See Figured.) The retention of the arm in its normal position is insured by a spring 52, secured at one end to the head and bearing against one side of the arm.
When the master wheel is not located opposite a' column totalizer, that is to say, when the printing point of the machine is located outside of the columns being totalized, the cam 46 will. hold the yoke'l? out of engagement with the key levers, so. that no movement will be imparted to the master wheel from the numeral keys when the latter are depressed for the purpose of printing numbers other than those embraced within the desired computation. When, how-' ever, the advance of the carriage brings the master wheel adjacent to a columntotalizer, the upper end of the. tri arm 47 is brought into contact with a trip flange 53, preferably depending from the front of each column totalizer. See Figure 3,.) Asthe carriage continues to advance the, trip arm will be swung back, and as'its independent movement is prevented by the ledge 59, the roclcshaft will be rotated and the cam 46 turned down to a horizontal position, for the purpose of restoring the operative relation between the actuator yoke 17 and the key levers by the time the master wheel moves into operative relation with the number wheel of highest order.
This relation of the parts will be inain tained while the master wheel is traversing the series of'number wheels, because the trip arm will be in engagement with the bottom wall of the flange 53, and will not pass therebeyond until the master wheel has moved out of coincidence with the number wheel of lowest order. When, however, the master wheel has moved beyond the totalizer, and the trip arm has moved beyond the flange by reason of the step-by'step advance of the carriage, the spring 48 will restore the yoke-elevating cam 46 to its normal posito avgain eliev the numeral k y levers of any unnecessary burden. During the retraction of the carriage to begin a new linc'of writing, the trlp arm 47 willagaln .contact with the trip flange 53, but instead of rocking the shaft 44 as before, will rock independently of the shaft in opposition to the spring 52, which latter will restore the'arm to its normal upright position when the flange has been passed. 4
Thus the machine may be said to comprehend a plurality of column totalizers, an actuator therefor, a series of keys normally out of operative relation with the actuator, a traveling carriage, and means for automatically effecting an operative relation between the keys and the actuator when the latter is presented to either of the totalizers during the advance of the carriage.
In addition to the automatic means for elevating and depressing the yoke 17, I prov'iclea second yoke-elevating cam 54, opposed to the under side of the yoke preferably at one end thereof, and mounted upon a manu ally-operated roelesha ft 55, journaled in a bearing sleeve 56 and extended through one efnd 'of the casing 5, beyond which it is provided with a knurled head 57'. The cam 5i constitutes manually-operated means for toan disconnecting the keys from the comp'uting'mechanism when it is not desired to utilize the latter. a
' We have now seen by what instrumentalities: provision is made for operating the number wheels of the several column totalizers by' an actuatoror master wheel, automatically 'connected with operating keys whenever it is presented to a column totalizer. It is 'nbi'v in order to deseribe'the means for op erating the number wheels of the grand totalizer in synchronism with corresponding numberwheels of any column totalizcr with which the master wheel 22is engaged.
The grand totalizer 12 is mounted, as here- .tofo'r stated, nponone end of the barS, and
its sidewalls are extended forwardly to form bearingbrackets 58, through which the actuator shaft 37 is extended. Upon this shaft, bet een the brackets is splined the grand master wheel 59, which, like the column master wheel is toothed for diieet engagement with the number wheels of the adjacent totalizer. Sincethe grand master wheel is splined upon the actuator or master Wheel shaft 37, it necessarily rotates with the shaft. but'the latter is capable oi independent longitudinal movement, so that while the grand master wheel 59 rotates in synchronism with the column master wheel 2-2, the latter is capable of such independent movement as 15 necessary to present it to successive column totalizers. In other words, this character of mounting of the grand master wheel limits its lateral or sidewisc movement to the confines of the grand to- 'talizer: and permits the column master wheel 22 to have unrestricted movement entirely across the printing area of the platen, and at the same time-maintains that operative relation between the wheels which insures their rotary movement in unison. Beside this synchronous movement; the two master Wheels must also be advanced in unison during the traverse of a column totalizer by the master wheel 22, as it'zi's obvious that the grand masterjwheel should'operate that number wheel of the grand totalizer which correspondsin order to the number wheel of the column totalizer which is being rotated by the column master wheel.
We have seen that the advance of the column master wheel from one number wheel to the wheel of -nekt lower order, is effected by'the ste by-step advance of the carriage." I there ore utilize this element for the corresponding ste by-step advance of the giand'master wh ee l Extending between the'brziekets 58, vin a plane somewhat below andin advanee o'f the shaft 37, is a short shaft 60, upon which is mounted a laterally-movable shifter, 61, having a bifur cated upperend 62, embracing the adjacent side of themaster wheh59 the master wheel and fshitter being normally retained V opposite the numberlwheel of l'iighest 'order by springs 63311161 fi4iei eircli rig the shafts 37 and 60,"andQnterp'Gsed b'etjveen the right hand bearing braeketlandtlie master wheel and shifter; respectively.

One of the projections orqblocks 66 is; provided for each of the several columntotalizers, and by the adjustment o'f these' blocks upon the bar 67, they may be so arranged that whenever the column master wheel 22arrives opposite the number wheel of highest order of any one of the several column totalizers, one of the blocks 66 will be in engagement with the shifter 61, so that as the carriage is advanced one step, both master wheels will be advanced in unison to the next lower number wheels of the column totalizer and grand to talizer, respectively. Thus assuming that the master wheel 22 has moved into coincidence with the number wheel at the lefthand end of one of the column totalizers, one of the blocks 66 will be in engagement with the tail piece of the shifter 61, as shown in Fi ure 12.
with the parts in these positions the depression of a key will effect more or less rotary movement of the actuator 22 and synchronous movement of the grand master wheel 59. Synchronous movement will thus be transmitted to corresponding number wheels of a column totalizer and the grand totalizer, and as the key rises the carriage will be advanced the distance of one letter space. This advance of the carriage will obviously move the master wheel 22 into coincidence with the next lower number wheel of the column totalizer, and will also advance the shift bar 67 a like distance. The block 66 carried by the bar and engaging the tail-piece of the shifter 61 will thus cause suflieient lateral movement of the shifter to advance the grand master wheel 59 to the next lower number wheel of the grandtotalizer, against the resistance of the springs 63' will finally present the two master wheels to j the number wheels of lowest order. At such time, the tail-piece 65 of the shifter will be disposed in contact with a trip device having the form of a cam projection 68, extending from the right-hand bearing bracket 58. Upon the next advance movement of the carriage, both master wheels will move beyond the number wheels of the totalizers, and the tail-piece 65 of the shifter (riding over the inclined face 69 of the cam 68) will' be swung on the shaft 60 as an axis, to move block 66, which, as we have seen, has efl'ect: ed the advance of the shifter and grand master wheel from one side of the grand totalizer to the other. As soon as the tail-piece 65 of the shifter moves out of engagement with the block or projection 66 on the shift bar, the springs (53 and 64 will retract the master wheel and shifter, restoring the nornml positions of these parts and presenting the tail-piece (35 in position to be engaged by' the next block on the shift bar, when, by rea- Son of the advance of the carriage, the master wheel 22 arrives opposite the highest number wheel of the next succeeding column totulizer. As the numbers are recorded in this second column, the second column totalixer and the grand totalizer will be synchronously operated in a manner exactly similar to the operation just described in Connection with the first column totalizer, and the same operation will be repeated when numbers are recorded in any addithe left ofthe shifter-615,11; e rear front coranism,;s1ichi as is disclosed; in: the =Eaganke+ tomatic resetting mechanism,.to a proper iunderstanding of which it is necessary? to 'havdsomidea of the specific construction tional column for which a column totalizer has been provided, it being obvious that the recording of numbers outside of the columns intended to be embraced within the COTDPIIP tation will not affect any of the totalizers, since the numeral keys will be out of operative relation with the master wheels whenever the printing point of the machine is disposed in the intervals between the columns.
It will now be noted that while the column totalizer is concerned only with the numbers printed in its individual column, the rand totalizer is operated whenever a num er is recorded in any one of theseveral columns for-"which column totalizers are provided, and it follows therefore that while the numbers in the individual columns will be embraced by the computations of the column totalizers, the numbers'recorded in all of the columns will be embraced by the computation effected by the grand totalizer, the latter registering the grand total of the'several c'olumns and the former the column tals. The retraction of the carriage 4, to begin a new line of writing, will L's-positionthe master wheel 22 in position who again advanced to successive column totalizers, and as the shift bar '67 moves back with the-car rings the blocks will be a ain positioned to nor. 70 of each block bei'ng cut away at an angle to compel the tail-piece 65 to ride over the'blocks as tlielatter are presented thereto during the retraction of the carriage.
It is of course necessary to provide means for resetting the totalizers' at'zero after the result of a given: computation has been ascertained and transferred to the work-sheet, and while manually-operated: resetting mech 10.5 Smith application hereinbefore' identifiedgi may be utilized, and in fact'is show n iII'GUlI-.-
said tail-piece out of engagement with the inaction with the grand totalizeii'l P equip the column totalizersat least with: an-
and-operation of-the totalizer construction. Therefore before proceeding with the descriptinn of the resetting mechanism, I shall describe as briefly as is consistent with clearness the manner inwhich thenumber wheels are'mounted and the mechanism directly associated with the number wheels, which mechanism, though not constituting art of 12,0= the present invention, is cooperative y:con nected with the novel resetting mechanism to, be hereinafter described. Within alined openings in the side walls of each totalizcr casing13, are located bearing collars 74 and 75, within which isjournaled the number wheel shaft 76, rotatahly supporting the several number wheels. (See Figure 8,) This shaft is normally stationary, and upon it are fixed a series of sub stantially disk-shaped transfer cams 77, one of which is located within the recessed side faceof each wheel. Each wheel is provided, upon the bottom face 78 of its recess, with .a pivoted transfer pawl 79, (see Figures 8, 9
and 10) having a tail-piece80, urged outwardly by a flat spring 81 and formed at its opposite end with a beak 82. The major portion of each transfer cam is'concentric with the shaft 76, but between the opposite be seenthat the rotation of the latter in the direction of the arrowIwill cause'the beak 82 ofithe transfer pawl (shown in dotted lines) ito'ride upon the plain face 83 of the cam during: eight I increments of movement :oftherwheel, thatis to say, while the numbers S are successively presented before the'sight opening. Atthe end of the eighth increment of movement, the beak will drop intothe resetting notch 86, and during the next or-ninth increment of movement (which presents the. digit 9 of the wheel f to-the sight; opening) the beak of the pawl will travel ownzintdthe depression 84 of the cam to engage a tooth of a ratchet wheel 87,
formed (as shown in. dotted lines) upon the adjacent? side face of. the number wheel g of-next higher order. wThus, an engagement will'lie-eflectedibetween the two. wheels, (see Figure 10) so that=as the final increment of ;movement' is imparted to the wheel f, a corresponding incrementof movement will be' imparted to the wheel of next higher order, tO-Wit, the wheel 9. T I
The: springs-81 are employed for the purpose of holding the beaks of the transfer pawls, against the edgesof the cams, but the positive engagement of'each pawl with a toothof the adjacent ratchet wheel at the proper time, is efi'ected by a slight swell or projection 88;'formed on each transfer cam adjacent to the resetting notch thereof. (See Figures 9and 10.) As the beak of the pawl approaches'the depression 84 pf the cam, its tailpiece rides upon the PI'OJBClZlOn 88, which positively swings thebeak of the pawl into the depression to engage the tooth of'the adjaoentratchet disk as the pawl advances.
It will be noted by reference to Figures 9 and 10 that the transfer cams are of greater diameter than the ratchet wheels 87, except where said cams are depressed to provide for the projection of a single tooth to be engaged by a pawl when the latter 1S moved down to the bottom of the depression said driven wheel will: be moved by its locating before thenext increment, of movement of the wheel f'iscommenced. By reason of, this relation of the parts, eachcam Will serve.
to, hold the pawl of its wheel out of engagewheel, except duringthe tenth increment of movement, so that each wheel will have;in-
dependent movement fonnine-tenths of each complete rotation, and will havecooperative engagement with the next adjacent wheel to the left during the final tenth: of'each rota tion. i
. ment with the ratchet disk, of theadjacentv For the. purpose of locating register .1
ing wheels with. accuracy, so that theidigits will always :be disposed 'in exact alinement before the sight opening 14, I provide what I may be termed locatingplates 89, disposed to slide, in suitable "guldeways 90,-formed in horizontal guide,-plates 91, secured'rigidly within the casing, 13. (See Figures 8, 9 and each number wheeh and each'plateisfprmed at its frontend with a pair ofpallets 92 and 1 93, which engage the teeth of the-,adjacent' number wheel in a, manner to, locate; the latter accurately inpropen positionand to wheel or the adjacent number wheel. The functionofthese plates 89 will be clear One of these iplates is provided for I hold it untilpositiyely rotated bythe master when it is considered that the transfer pawl engagingpatooth, ofan adjacent wheelmust a move entirely out of contact. with. said tooth bygth'e time the tooth carrying the pawl' clear that unless ilocatting meansotheri than the pawlis provided, the final, movement of the'wheel, to which motion is communioated The locatingplates are therefore so con.
structed that after the pawl of. what may be termed a driving, wheel positively moves' the engaged or driven wheel a given distance,
ositively late independently of the pawl, so that while both wheels will be positively located,.the edge of the engaged tootlrwill have entirely disappeared within the edge of the cam by the time the movement of the pawl is completed. By reference to Figure 10, it will be seen that when the beak of a pawl is in engagement with the tooth of the adjacent wheel and is ready to propel the latter, the pallets 92 and 93 will be in engagement with the teeth of the wheel to be driven, to hold it in posiw th paw w' db e eimby reason tion until positivelyactuated. It now the driven wheel is positively rotated by its engagement with the (lriving vheel carrying the pawl, its locating plate will be forced rearwardly against the resistance of a spring 94, one of which is provided for each of the plates. The plate, being thus moved back to the position shown in Figure 9, will permit the rotation of the driven wheel, and just before the latter has reached the end of its increment of movement, and while the pawl is still-in engagement with theratchet tooth, the upper corner of one of the peripheral teeth of the driven wheel, (see 0;, Figure 9) will pass the point of the pallet 93 and will be presented to an inclined impulse face 95, formed on the pallet; The impulse face 95, being inclined with respect to the direction of movement of the locating'plate, will,as said plate is urged toward=the wheel, com pel the downward movementof the engaged tooth a sutlicient distance, to accurately locate the wheel, and to cause the ratchet tooth thereof to be entirely disenga ed from' the beak of the pawl and to be with rawn within the edge of the cam disk. When the plate 89 has finally come to rest after locating the wheel, the upper and lower pallets 92' and 93 will be in engagement withthe teeth of the wheel, as shown in Figure10, to hold said wheel' in its properly located'position.
For reasons fully explained in the application of Laganke and Smith, it is desirable to provide positive locking mechanism for the numberwheels. This mechanism includes aseries of locking dogs 96, one for each of the number wheels with the exception of a, as this wheel is never operated by movement transferred from another; These dogs are locatedbelow the wheelsand are mounted on a shatt 97'," extending between the Side wallsof the casing 13," Each dog is yieldinglyiurgedto its disengaged or unlocked: position -by-a spring 98z In such position -of the-do a thin t'rip plate 99, located at one end thereof, extendsin a plane between the wheel served 'bythe dog and the adjacent wheel of next' lower order.
This disposition ofthe trip plate brings'it into the path of movementof a trip pinlOO, extending laterally from a tooth ofrthe wheel of'lower order. Each trip-pin extends from that tooth of the number wheel which bears the digit 4, in orden that said pin will engage thetri plate of a dog during the movement, 0 the wheel carrying the pin, from 9 to 0, a
We have already seen that the movement of any number wheelfrom-Q to O willbe accompanied by a single increment of, the adjacentwheel of higher order, and it will nowbe observed that since the trip pin 100 engages the trip plate of a dog duringthis same interval, the result will; be that when the adjacent wheel, and will at the same time operate the dog of said wheel to lock it positively when its single increment of movement has been completed. This will be clear by reference to Figures 9 and 10. In Figure ltlthe wheel f/ is about to be advanced one-increment by the wheel f, whose transfer 'pawl is shown in dotted lines. As thewheel f advances under the impulse of the master wheel, its pawl will pick up and advance the wheel g, and its trip pin 100 will engage the trip plate 99 of the dog 96, serving the wheel 9, so that the dog will he rocked against the resistance of the spring J8. and will have its rear end thrown up to its engaging position, asshmvn in Figure I). This movement will occur just as the impulse face 95 of the locating plate of the wheel g is about to advance for the purpose of locatin the wheel. Therefore, theadvance of-the locating plate will assure the complete movement of the wheel g, and the dog will prevent excessive movement thereof. one tooth of the wheelbeing rigidly retainedbetween the engaging end of the dog and the impulse facecf the locating plate. It should be noted at this point that as the dog is swung to its engaging position, the trip pin which has imparted positive movement to it will pass over and beyond the trip plate to the position indicated in Figure 9.
At this time the wheel carrying the pin, as
ploymentof a series of dog-retaining plungers 101, mounted in suitable guides 102, extending across the casing. 13 and urged for wardly by springs '103, each encircling a plunger and hearing at its ends against one of the guides and-a shoulder formed on.the plunger, respectively. When the-dogs are in their unlocked positions, as indicated in Figure 10, theyv are disposed to'hold the plungers in their retractedpositions, but immediately upon the movement of a dog to its engaging position, its plunger moves forward to engage the under side of the elevated end of a dog. and thus prevents its retraction when the trip pin moves beyond the plate. As the number wheelsare operated in succession during the travel of the carriage in the direction of letter spacing, such of said number wheels as are advanced by transferred movement will be positively locked bythe dogs and vwill remain locked durin the advance of the carriage, since it is evi cut that no number wheel can be twice operated byv movement transferred to it from another number wheel during a single travel of the actuator across the totalizer.
It is necessary, however, to unlock the number wheels: before. another number added to that already registered, since it would otherwise be impossible to rotate the wheels by either-transferred movement or by the direct action of themaster wheel. Many ways of accomplishing the desired end might be suggested, since the simple retraction of the dogretaining plungers 101will permit the springs 98 to instantly retract the dogs. We prefer, however,. to provide automatically-operated means for unlocking the num ber wheels upon the retraction of the carriage. The illustrated embodiment of the unlocking mechanismcomprehends the employment of an unlocking frame 104, mounted to slide in horizontal guide grooves 105, formed in the side of the casing, and engage ing at its rear; end a-seriesof pins 106, depending from theplungers; The-pins 106 grooves 107,;designed to prevent their lateral udispla'cementa TheZ unlocking frame 104 is of light openvform and isiprovided at its front endiiwith a'vei'tical flange :108,-.atI the lower edge .of which is located a hori'zon talledge 109." (SeeFigures 1, 3; 9 and-10.)
By moving the unlocking frame: rearwardly to the .position indicated inFigure -10,: such of the plungers as are inytheir forward-post tions willbe retracted, permitting the-dogs to.dropfbackout of engagement with the wheels. This movement of-the vframe may be eifectedtmanuallyybutsince, as heretofore explained its automatic retraction is contemplated, I provide what may be termed aim/unlocking cam 1 10;in the form of a plate movable withv the carriage and .'-preferably hinged betweenfla' pair of ears 111', projecting-rearwairdly from the base plate 33 of the supportingfra'me for the'actuator. The cam' 110 is normally retained in a horizontal position by a stop lug 112, pro- 1 j ecting: from the hinged edge thereof and engaging the under side of the plate 33. In this: position of the cam it is-disposed in the horizontal planeof the ledge 1090f the unlockingframe and when retracted with the Carriage its inclined face 113 contacts with one bornerof the led e, and consequently forces theunlocking' rame rearwardly as theretraction? of the carriage continues. Thus, iwhenever the? carriage 'is" retracted after? having advanced the masterwheel of the computing mechanism across the series ofnumber wheels of the column totalizers, said wheels will be automatically unlocked by the successive actuation of the unlocking frames. and may be again operated in the morgue to either unlocking frame, as this would prerent the forward movement of the frame, and the retaining plungerswould in consequence be prevented from moving forward to retain the dogs. It is for this reason that the cam is hinged to permit it to occupy a position above the ledge 109, during the advance movement of the carriage The under side of the-cam 110, at the end thereof opposite the inclined face113, has a beveled face 114, which rides upon the left-hand end of the ledge 109, and thuselevates the unlocking cam to permit it toride over the ledge as the carriage advances e have now seen how the transfer movements of the number wheels are effected, the mannerv in which the wheels are accurately located, the provision made for positively locking the wheels, and the arrangement of ,.th eyautomatic means for unlocking the are i d t, th n-low d ithi id therefore remains to be described in what manner the computing mechanism is reset or restored to zero after any given computation has been completed. 1
engaged by aratchet lll. formed integralw with or otherwise fixed to a cam l18,and
a pinion 119; located beyond the cam. The p1n1on';11 9 disposed forengagement bya reciprocatory, rack -ban.120, keyed in; suit able bearings and urgedforwardby a spring 12 1, oritsjequivalent, :which'mounted upon the side-of thezpasingand is disposed to bear against the .rear vendof the rack bar, as shown; in FigurelB. Rearward movement ofthe rack bar against the resistance of the spring 121 is effected by what may be termed a resettingarm 122, movable with the carriage 4, and contacting with an anti-friction roller 123, mounted at the front end of the rack bar.
The resetting arm -122 is disposed at an inclination with respect to the rack bar, and acts as a cam; serving (as the carriage is retracted) to move the rack bar rearwardly, and thus rotate the pinion 119. For the purpose of permitting the arm 122 to ride past the rack bar without engaging the latter during the advance movement of the carriage, said arm is pivotally mounted upon a stud 124, extending from a boxing 125 mounted upon a short rock-shaft 126, and having a stop flange 127. The arm 122 is urged to its normal position by a spring 128, an in suchposition the stop shoulder 129 formed on the arm engages with the flange 127, to hold the arm rigidly in proper position to effect the rearwardnmovement', of the rack bar. iwvhen however, the carriage is advanced, the arm 122*striking-the roller will swing back against the resistance of the.
with a thumb piece orzhandle- 130, which.
maybe depressed tovrock the sh'aft126, and thus elevate the resetting arm out of the path of the rack bar.
When one of the rackbars is moved rearwardly by the resetting-arm 122, the/adjacent pinion 119 is rotated. The ratchet wheel 117, moving with-the pinion, will en-f gage the pawl 116 on the resetting head115, and as said head is fixed to the shaft 76,
rotary movement will beimpartedto' thelatter and to the transfer cams mountedthereon. Sincethe resetting-notches 86 of the several: transfer camstare accurately almed, and since the transfer pawls bear an identical relation to the number wheels, the rotation of the shaft 76 will effect the engagement of the 'resetting notches with the beaks of the pawlsuand when Such engagement is effected the similardigits of the several-number wheelswillf be-alined.
This'result will of course be efl'ected by a complete revolution of the shaft, but as the starting positions of the pawls are two increments of 'movement in advance of the resetting notches, (see Figure 9) the throw of each rack bar is sufficient to move the shaft somewhat more-than a complete rota-- tion, in order that the resetting notches of th e 'eams will move a sufficient distance to properly position thepa'wls and to present the several number I wheels at zero, after which the shaft may be turned back topresent the resetting notches the distance-oftwo increments'in rear of the beaksof'the' pawls. This backward movement of the shaft 76' is effected at the end ofthe retractile movement of the rack bar 120 under the impulse' of the spring 121.
The rack'bar is provided at its rear end with a projection 131, which, as the rack bar i s approaching thelimit of its'retractile movement, contacts w th a pin 1 32', pro jecting' radially from theshaftf 76 at a point beyond the pinion 119. The normal osition of this pin is vertical,as shown in igure '13, and when the wheels have'been reset' the pin will have made one complete revolution, plus the distance of two increments of movement of the shaft, and will assume the position shown in Figure 15, which is slightly beyond the vertical. Therefore, as the rack bar moves forward after having efiected advance movement of" thecarriage.
the resetting of the wheels, the projection 13L thereonwill contact with the pin 132,
restoringit to its normal vertical position, and therebyrotating the shaft in the re verse direction and movingthe cams back to properly position: the resetting notches thereof. It will of course beevident that since the-pinion 119 and the ratchet wheel 117 are mounted loosely on the shaft, reverse rotation of these elements, as the rack he! moves forward, will not be accompanied by corresponding movement of the shaft.
The position of the unlocking=cam upon the carriage is such that as said carriage is retracted, the unlocking frame 104 will be retracted before the resetting aim is brought into contact withthe front: end of the rack ban The numben wheels will therefore be automatically unlocked prior to the automatic resetting thereof, but: it will be remembered that whenever: a wheel is moved to present 0= before the sight opening, the dog of the next adjacent wheel will be auto- 'matically'thrown into engagement therewith, andthe -plungers'will spring forward 90 to holdthe dogs in'engagement. It is evidenttherefore that-unless some means are provided "for holding the plungers back when the wheels reaehtheir reset positions, said wheels 'will' be automaticallylocked at the {endf of the resetting operation and will be incapable of actuation during the next It-i s forthis reasonithat the cam 118 has been provided- This cam is disposed in op- 1 erative relation towhat may be termed an unlobki'ng levei-' 133'- of bell crank form, ful crurn"ed'f"'onthe side of theregister casing.
One end of -this lever isdisposed 1 against theperiphery of th'e 1*18'an'dits opposite" 1 5 end is' -arrangetl inoperative; relation to a projection 134, extending throughthe side 'of t-he casing-'frornthe;unlocking frame 104.
Normally the lever? 133 engages a'depression 135- in the face 'of th'e-ca1n= 118, but as the no latte!"rotates=,=during thee-resetting of the wheels; the'de ression-will move away from the lever, an the latter will be rocked to retract "the unlocking frame, which thus obstructsEthel-forward"movement of theplungersk" Whenfthe' wheels are completely reset,'the-carn willbe'inpositionto hold the lever '1-33 and' the unlocking frame in" their retracted" positions; and consequently while the locking dogs' are positively moved into engagement with the number-wheels, when the latterj reach their; reset positions, the plungersf w-ill be prevented from moving forward to retain the'dogs, and the latter will consequently drop back to their disengaged positions as soon as the number wheels are relieved of tension by the reverse movement of the shaft. When, however, the rack bar has returned to its forward position, thecam 118 will have been moved .ward movement of the plungers will be unrestricted to permit the performance of their proper .functions as retaining devices for the dogs, when the latter are automatically thrown up to lock the wheels during the advance of the carriage.
The resetting mechanism illustrated in connection with the grand totalizerisidentical with that disclosed in the-Laganke- Smith application aforesaid, and since an understanding thereof is unnecessary in connection with my-present invention, thedescription thereof has beenomitted.
At this point attention may bedirected tov the fact that the'fian'ges 53 of thecolumn totalizers constitute trips whichare independently. adjustable parallel to the line of writing and control theioperative connection between the numeral keys and the actuator and which serve by their adjustment to determine the locationof the columns to be romputed,ithat is to say, the location of the coliunnson, the work sheet. Furthermore,
when considered in connection'vwith the grand totalizerlQ, these strips 53 may be said to be adjustable independently of said totalizer for. the purpose of determining the location of the several columns to be included in the computation effected by said grand totalizeror computing device. F urthermore, either of thesetrips53 which is adjustable independently, of the computing device 12,will be seen tocontrol means, towit,,the yoke 17 and associated parts, whereby an operativerelation will be established between the computing device and, its operating mechanism, when the printingmechanism is disposed to printina iven column, I
and whereby an inoperative re ation of. said parts .will be automatically established. to permit digits to! beprinted beyond thecolmun, that is to say, tout-he right thereof, without causing the computing device to be operated. v
Attention is also directed to the fact that the blocks which are relatively adjustable on the bar 69 and, move with the carriage 4, constitute trips controlling. the operation of the master wheel advancing mechanism of the computing device 12 and. automatically cause the advance of the master wheel 59 to he inaugurated at the proper point or points in the travel of the carriage. Furthermore, the totalizer 12, in addition to its function as a grand totalizer for several parallel columns of numbers, may also be considered as a cross column totalizer inasmuch as it is capable of adding a series of numbers printed one after another in the same line instead of one under anotherin a column. This capability necessarilyresults from that re lation of the partswhich enables a plurality of columns to be totalized, because, as is obvious, the totalizing of a cross column is simply the totalizing of a series of numbers each of which is printed ina difierent column position. i
It 15 thought that from the foregoing the construction and operation of my novel calculating mechanism will be clearly apparent, but, while the illustrated embodiment of the invention-is believed at this time to be preferable, I'wish to be distinctlynnderstood as reserving to myself the right to effect such changes, modifications and-variations of the illustrated structure as may fall properly within the scope of the protection prayed.
