To all whom it may concern:

' Beit known that I, AooLPHUs G. MEIER, a citizen of the United States, residing at the city of St. Louis, *State of Missouri, have "invented certain new and useful Improve 'rnents in Calculating-Machines, of which the following s a specification, reference "being had therein to the accompanying drawin s.

This invention relates to machines. or mechanically adding individual items or amounts into an; aggregate or total, and

' especially to adding-machines of that class pawl that act-mates .the

which are adapted .to print the lists of such items or amounts that are registered, to add up such lists, and to print the total of the added items at any desired time.

forming part of this which like numbers of parts wherever they s de elevation .of the In the drawings, specification and in reference denote like occur, Figure 1 is amachine; Fig. 2 is a longitudinal view on the line;2,2,-Fig. 5; Fig. 3is a perspective detail of a part of one of the rack-bars;

10; Fig. 12 .is'a side elevation of one of the partition-plates that separate the individual g adding-wheels ,of the accumulating mechan ism; Fig. 13 is-a top plan View of the same member; Fig. 14 is an enlarged sectional detail of a portion. of the accumulating mechanisrr, onxthe line l4.-14:, Fig. 10; Figs. 15,

16, and 17 are details of other portions'of of the machine.

after the operating mechanism'isassembled, said casing preventing dust and dirt from settling in the interior of the machine. Cross rods 2 extend from one side to the other of the machine, said rods having screw-threaded, shouldered heads 3 which heads extend through suitable perforations in the side plates 1. Nuts 4 are screwed upon 3 outside of the side-plates 1, thusfirmly seated on the shoulders at the junction of the heads and rods, the cross-rods 2 and sidelates -1 being thereby bound together to form a skeleton in which the operating parts aremounted.

the heads which are Rods similar in construction and arrange ment to rods 2 serve as shafts, or otherwise, to support certain operating parts, such rods being, for convenience, designated by specific reference numerals. Other cross-rods,

5, are provided for various purposes, these rods being-tapped at their ends for the re ception of screws 6, which are inserted through perforations in side-plates 1, and

thus these rods, also, can be held'fixedin any Rods 5, unlike rods 2, are

desired position.

heads adapted to extend not provided with through the side-plates 1, but are of thesame length as the internal width of the machine. Thus, rods 5, with necessary parts attached thereto, can bepIaced in position in the machine after the skeleton, consistin of side plates 1 and cross-rods 2, is assemhled, and, since many of the operating parts are piv otal relation to, or otherwise supportedby,

said rods 5, these parts mayiobviously he) 5 and then the whole group mounted on rods v k of parts placed in,.or withdrawn frorn,,;the machine, without itslheing necessary to-remove'the side plates 1 or to loosen any-of the'cross-rods 2.

' Rotatably mounted on cross-rod or 7 are the sectors 8, the number of sectors provided depending on the desired capacity In the drawin s, nine sectors have been shown, which g ves the machine a. capacity for listin any amount from -1 to 999,999,999; but t e same construction may be" employed, and the saine mode of o eration applied, whatever be -the number ot sectors and consequent capacity of the machine.

approximately circular 'portion 9, and the radially-projecting arms 10, to which are secured, by means of screws 11, the arcuate keys or finger-pieces 12, composed of a wide Thesesectors consist ofan I about one-fourth of an inch, or less.

,the same distance as it is desired to have between the different columns of figures as they are printed, which distance is usually To place all'the finger-pieces 12 within so narrow a compass, however, would prove inconvenient; so the radial arms 10, where necessary, are bent so as to be L-shaped, as. at 16,

and the result is that theparts of the arms I 10 to'which the finger-pieces 12 are secured,

are spaced apart a considerably greater distanee than are the circular portions 9 from which arms 10 project, and thus, the finger pieces 12 may be made of such dimensions, and placed far enough apart so that the key board, which consists ofthe finger-pieces 12, will be of a size convenient to operate, and will not beunnecessarily crowded.

The finger-pieces 12 are provided for the purpose of registering units, tens, hundreds, thousands, etc., by depressing the respective arms 10 and thereby partially rotating the respective sectors 8, the units-registering finger-piece being the one to the extreme left in Fig. 5, the tens-registering fingerpiece being next, to the right, and then the hundreds, thousands etd, following in order. Each of saidfinger-pieces is provided with a pluralityvof finger-holes or sockets 17 WVhen the operator wishes to register the number that is to be listed and added, he depresses the appropriate key, or, .if the number comprises more than one figure, the appropriate keys, the distance of such depression of each finger-piece governing, for the particular column which that key controls, the digit that is to be listed and added by the machine.

The numerals 9, 8, 7, 6, 5, i, 3, 2, 1, and 0 are marked in the finger-holes 17, beginning towardthe right in Figs. 1, 2, and st, thus indicating the socket in which the operators finger must be placed to secure the depression of any particular finger-piece the proper distance to print and add the desired number. Then the finger-piece is depressed, it is moved in the direction of the arrow, Fig. 2, until the finger of the operator strikes against the stop 18, when, of course, the finger can be moved no farther. Accordingly, the extent to which the fingerpiece can move at any one operation is determined by the act of the operator in placing his finger in a particular socket of such finger-piece, and depressing said finger-piece as far as possible. If, for example, it be desired to register. and add 6 the finger of the operator will be placed in the'socket designated by the numeral 6, and the finger-piece 12 thereupon depressed until the finger strikes stop 18.

Extending entirely across the machine, and journaled in openings inthe side-plates l, is a shaft 19, adapted to be turned by a knob 20 located exterior to the casing. Loosely pivoted on said shaft 19 are pawls 21, one pawl being provided for each fingerpiece 12. Springs 22, secured tocross-rod 23, normally keep said pawls 21 -in engagement with the fingerepieces'l2, one such springbeing provided-for each of said pawls, and, as the finger-pieces are depressed by the operator, these pawls are forcedinto'sockets 17, thus to retain the sectors 8, pending the printing operation, in any position towhich they mayhave been rotated by the operator. When any finger-piece 12 'i-s;depressed, an( the sector 8 to which it is attached thus caused to rotate upon the shaft 7, it is so moved against the resistance of a helical spring '24, one end of a spring 24: being securedto each sector at 25, and all the springs of the series'being attached at,their opposite ends to cross-rod 26. These springs normally tend to return the sectors 8 to the starting position shown in Fig. 2, but when any finger-piece 12 has been depressed,and its pawl 21 has been foreed into one of the sockets 17, the finger-piece and its sector are thus locked in place. i f i Bosses 27 are firmly fixed on shaft 19,-and, projecting'from each boss 27, is a pin 28 adapted to engage a pawl 21; When shaft 19' is turned in the direction of the arrow,

Fig. 1, by means of knob 20, the pins 28 coact on the pawls 21 which are thus forced out of the sockets 17 in which they may have seated, and the springs 24thereupon return the sectors 8 to the starting position. In this manner, after any item has been listed or printed, and added into the machine, the sectors are all simultaneously returned to normal position, so that the operationmay be repeated and further numbers added. Pins 31 secured to the pawls limit the return rotation of shaft 19, for, obviously, pins 28 can not pass pins 31, but will be caught thereby. A cross-rod 29, covered with rubber tubing 30, or other resilient material, against which the arms 10 of the sectors 8 may strike, forms a cushion-like stop-to limit the returninovement of the sectors and connected parts after the pawls 21 have been withdrawn from the sockets 17 in the manner above described.

As hereinabove stated, the finger-pieces 1,2 h avela rubber portion 13, and a metal por 1101114, and the pawls 21 are so loeated that they engage the metal portion, which will not wear out sd quickly, leaving the rubber portion untouched by the'- -fingers of the operator.

A plurality=of-arcuate lnet aigstrips 32, supported at one end by a cross rod 33 and at the other by shaft 19, is provided, and these strips serve as partitions to keep the various finger-pieces 12 from coming into contact with oneanother 4 x Projecting radially from the circular portion 9 of each sector 8 are the type 34, by

which the items that are to be added by the machine 'are listed or printed. These type bear the numerals O, 1, 2, 3, 4, 5, 6,7, 8, and 9, said numerals bein arranged sucoessivel from right to left, Figs. 2 and 4.- As each sector8 is given ap'artial rotation upon the depression of the finger-piece 12 secured thereto, the ty e 34. borne by said sector are carried ,upwar in an arcuate path until one of the type-faces is-in juxtaposition to the ribbon '35, The parts are so proportioned that the depression of a finger-piece 12 to the extent permitted when the operators finger is inserted in any particular socket 17 thereof will rotate the sector the distance necessary to leave thetype-face 34 which bears the same numeral as that by which said particular socket 17 is designated raised to a point opposite the ribbon 35. Thus, to use the former example, if the o crater should desire to print 6, he woul insert his finger in the socket marked 6, depress the finger-piece as far as would be permitted with his finger in that socket-,whereupon the pawl 21 would lock the sector in place by seating in socket '17, and, when the sector had been so locked, the particular type-face 34- that would be exposed to the ribbon springs 24 after the release of the'sec'tors by,

in Fi 515011 35. If desired, the parts can be so.

would be the one on which the character 6 appears. The return of the sectors to norma]. position resulting from the action of the actuation of" shaft 19, obviously, returns all the ty e-faces 34to'the positron shown '2', where no type at all are opposite than constructed that, when 81ers returned to normal ,tion, the particular t e-faee 34 bearing the character 0 ,wil exposed to-ribbon 35', this arrangement being preferred by man addin -machine users.

Formed integra with t e circular portion 9 of each sector 8, are teeth 36, whichmesh with the teeth 37 offer reciprocating rack-bar 38, there being one such bar for each sector.v As the finger -pieoes 12 are depressed, and the sectors 8 attached thereto rotated, the re;

s -tive bars 3'8 are forced toward-the right,

I igs. 2 and 4,, and, as the sectors are released and returned, the bars 38; are" drawn bac sliding wheels '43. Each rackbut thus of each raek-barf38 causes the appropriate adding wbeel 43 to rotate in the direction designated by arrow A,'Fig. 11, and pawls 44,'pivoted at 45 to the partition-plates 46, en age the teeth of each ratchet-whee142 and ock said'ratchetand addin wheels against return'movement. Rollers 45s pivotall mounted on cross-rod 49 ,Which v passes t rough the opening 50in each of the plates 46, are normallyretained in an elevated position by springs 51.- Said rollers support and keep their respective rack-bars 38 in meshwith ratchet wheels 42, but another series of rollers 52 is provided to prevent undue upward motion of rack-bars 38, which, if permitted, wouldcause unneces sa wear and tear on the mechanism;

en the" rack-bars 38 are returned to starting position, the pawls 44 having locked the ratchets 42 against return, the teeth 41 of the rack-bars ride over the teeth of the ratchets, and, as the rollers 47 are adapted to be forced downward against the pressure of springs 51, thereb allowing the teeth of the rackbars to ri e out of the teeth of the ratchets, the rack-bars 38 can be withdrawn toward the left, Fig. 2, without disturbin' the adding-wheels 43 or retracting themmm the position to which they may have beenadvanced.

On each adding-wheel 43 are placed ten type 54. The numerals 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, appear upon the type-faces 54 which radiallyproject'from each of the adding-wheels.

43, and by same the sum of the numbers that have been added is printed. All, parts are so proportioned that the depression of any finger-piece 12 rotates the appropriate adding-wheel thirty-six degrees every time that 1 is to be added by said wheel, twice so far when 2 is to be added, and so on, the amount of rotation depending upon the digit that is to be added. .At each operation of any key 12 accordingly, the adding wheel controlled thereby is rotated, from the position in which'it was last at rest, a distance 7 sufficient to leave exposed to ribbon 55 thetype-face representing the sum of the digit to be added and the one that was last in that position. Thus, if it should be desired to add 6 the finger-(piece 12 controlling the proper column Woul be depressed, as heretofore' explained, and the proper rack-bar 38 thereby advanced the distance necessary to rotate its adding-wheel 43 suiiiciently to leave the particular type-facebearing, the fi 6 exposed to ribbon 55, assuming that the addin -wheel had been at 0 when the ration e an. If the t -face 2 oftlfg adding-wh eel hadbee'n e ic p osed to the ribbon, it would have been advanced to 8 and so on, suitable carrying or transfer v mechanism being provided, by means of which each time an addin wheel passes iron: '9 to "0 one unit often or hunupportedin bifurcated yokes 48,

dred, etc.) is carried or transferred to'the wheel next higher in the series (the one adjacent on the right, Fig. 5) by advancing the latter wheel one number.

The various adding-wheels43 are mounted to revolve idly on a shaft 56, which is supported by the side-plates57. The ratchetwheel 42 connected with each addingwheel is located on one side thereof, while, on the side opposite, is secured a gear-wheel 58. Each adding-wheel is separated from the one adjacent by a partition-plate 46, which plates, as depicted most clearly in Fi 12, haveperforations 59 through which shaft 56 is adapted to pass, and two arcuate slots GOand 61. Attached to each partition-plate 46, or formed integral therewith by bending back at right-angles totheplane thereof the pieces of metal that are stamped out in punching the slots 60 and 61, are cams 62 and 68. The interior of each adding-wheel 43 ishollowed out,'and in the cavity 64 so formed is placed a pawl 65. These pawls are constructed in thevmanner shown in Fig.

j 16, having anenlarged middle loop-like part which surrounds the shaft 58, from which part pins 66 project into recesses 67 provided-therefor in the hub 68 of each adding-wheel 48.

Each pawl has a stud 69 projecting therefrom, and, also, has extended portions or heads 7 and 71. These pawls normally remain in a position with their studs 69 retracted as far inward as possible i. e., to-

ward the left, 14), but, as each addingwheel is rotated to the point where it is d8? sired to make the transfer, the lowerend 71 of the pawl carried by saidadding-wheel rides up on the proper cam 63. This forces the other end of the pawl outward, and

causes stud 69 to projectthrough slot 60. Each ratchetwheel 42 is provided with a plurality of sockets 72, separated by the beveled webs 73, and as each pawl 65 is thrown into operative position by cam 63, stud 69, projecting through slot 60, sinks into one of the sockets 7 2. As each addingwheel revolves, stud (S9 of the pawl carried thereby strikes one of the webs 73 of the adjacent wheel, and thus each wheel rotates in unison with the wheel next higher in the 'series during such length of time as its pawl is-thns permitted to protrude through the adjacent slot 60. In order to withdraw the pawls, cams 62 are provided, and, as the Wheels 43 rotate, the heads of the pawls ride up on said cams, and the pawl carried by each adding-wheel is thereby lifted out of engagement with'the adjacent adding-- wheel. The size of the parts, and their arrangement is such that each pawl is per-. mitted to project through its slot 60 during the time that the adding-wheel'by which it is carriedis passing from 9 to 0, and

no longer. 1 During such time, therefore the vanced, but, as the shaft pawls 80 is rotated, said pawls Wlll drop cated transfer is made, and at each revolution of any one adding-wheel 43, one unit, (or ten, or hundred, etc). and only one, is transferred or carried to the wheel next higher in the series, the latter wheel being advanced one number.

It will be observed, by reference to Figs. 2 and 4', that when any rack-bar 38 is in normal or starting position, the beveled teeth 41 thereon do not reach as far as the ratchetwheel 42. The purpose of this construction is to permit the finger-pieces to be depressed to v 0 without communicating motion to the adding-wheels. Unless the finger-pieces are depressed to 1 or beyond, the addingwheels do not rotate at all. i I

J ournaled in bearings 74 in the side-plates 57, and projecting beyond through the side, is a shaft 75, adapted to be rotated by a knob 76 attached thereto but located exterior, to the casing. Idlyrevolving on this shaft are gear-wheels 77, which, while the adding operation is in progress, mesh with, and are driven by, gear-wheels 5,8. In the hub 78 of each of said wheels 77 is a notch 79. Secured to said shaft 75 are bosses 80, each boss pivotally supporting a spring-pressed awl 81, said pawls being in alinement witheach other. When the adding operation'is in progress, and the adding-wheels 43 are rotated, the gears 58 cause the gears 77 to revolve idly in the direction indicated by arrow B, Fig. 11, but when it is desired to clear the machine, or return all the adding-wheels to O, shaft 75 is rotated in the directionindicated by said arrow. As

the shaft 75 is thus rotated, the pawls 81- one by one drop into the notches 79. This locks the heretofore idle gears '77 to the shaft 75, and causes them to rotate therewith, and, as these gears 77 mesh with the gears 58, the latter are, also, rotated, carrying with them the adding-wheels 43. After the addin notches 7 will be variously positioned around the shaft 75, the position of each notch depending on the distance that the particular adding-Wheel which rotates its gear 77 bearing said notch has been ad- 75 bearing the into the proper notches 79- wherever they may be, and each adding-wheel Wlll be f picked up and its rotation commenced as soon as the proper pawl drops into the notch 79 on the gear 77 opposite said adding operation has been completed,

adapted to aline with anothermark on the side-plate 1. l Mounted on a stud-like shaft 82, which projects from the'side-plate. 1,.is the operatlug-lever 83, which is moved when it is desired to print the various numbers that are registered, or .the sum thereof. Springs 84 and 85 have one'end secured to a button 86 formed on the lower end of this lever, and their opposite ends are fastened by rivets 87 to -the sid eplate -1. When this lever is' movedgn elther direction the contraction of the particular spring that has been expanded tends to return said lever to the normal position shown in Fig. 1; Brackets 88, pro- 1ecti-ng from side-plates 1, have screwthreaded. openlngs in which are placed thumb-screws 89. These s'crews lie 1n the are through which the operating lever 83 travels, and limit the movement thereof,-

and, obviously, by turning these screws one way or the other, the limit to which the op-.

crating-lever; may be moved, can be regulated to whatever extent may be made necessary in the adjustment of the parts of each individual machine. Nuts 90 ma tightened to hold the screws in ti'on.

Encircling the stud-like shaft82, and se-'' cured to lever 83 by means of screws 91, is a gear-wheel 92, which rotates as the lever is moved. Thlsgear meshes with and drives gear-wheel 93, which is secured to a stud like shaft-:94, ournaled in a suitableperforation provided thereforin side-plate 1. Formed integral with shaft 94 is a rocker-arm 95,. and on. the opposite side of .the machine is asimilar rocker-arm 96, pivotal'ly mounted, by

means ofstud 97 in the opposite side-plate 1. Depending from each rocker-arm is a flat stud 98, which studs are inserted in slots 99 formed in t'he ends of rod 100, said rod thus serving to cross-connect the two rockerarms 95 and 96, thereby causing them to move in unison. Consequently, when ..the rotation of gear 93 .causes shaft 94 to revolve,

the rocker- arms 95 and 96 rotate in unison about studs 94 and 97 as an axis, thedirec-,

. tion of such :rotation being. determined by roller isgiven a partial revolution at eachoperationof the lever 83, and the paper ribbon 104,'onwhich the items are to be prmted,

.is thus advanced to leave suflicient spacethen be xed' posibetween the difi'erent lines. Two shafts 106 and 107 are, also, journaled in the rockerarms, said shafts supporting friction rollers 108 and 109 which bear against the platenroller 103 and keep the paper ribbon 104 stretched taut. ported on a core 111 which rests in sockets or slots 112 provided therefor in the sideplates 1, and, as the ribbon 104-leaves the reel,.it passes between friction-roller 108 and the platen-roller, thence around the platen, being held thereagainst by the other friction roller 109, and emerges through the s cebetween'. the two rollers 108 and 109, rom whence it can be removed at the operators convenience whenever'the desired addition and im rint have been completed.

A bi urcated pawl 113, the two arms 114. and 115 of which are spaced apart a sufficient distance to per-mit'the rocker-arm 95 'to pass therebetween, is provided at one end with a sleeve 116, by means of which and a screw 11'? passing therethrough and fitting into a tap-hole (not shown) provided therefor, said spring is mounted upon the side- The paper reel 110 is supplate 1. .Ifdesirable, however, the pawl 113 may be mounted in any other convenient manner. The wl'is so arranged that itsshort arm 114 has the ath of travel of the ratchet-wheel. 105, an, as the rocker-- arms and 96 are swung toward the left,

Fig. 2, am 115, which is, in reality, a spring pawl, engages the teeth of ratchet 105 and causes said ratchet to rotate, together with the platen roller 103, both of which members are fixed to the same shaft 102. This operation secures 1 the step-by-step forward feed of the paper ribbon which it is. necessary to provide, in order to have each number printed'on a separate line. In the other .arm, 114, is a recess 11.8, and a pin 119, project-ing-from rocker-arm 95, is seated therein when the parts are in the normal position depicted in Figs. 2 and 4. \Vhen the platen is moved out'of this position, the pin 119, riding outof said recess, slightly elevates arm 114, and, in consequence, arm or pawl- 115is, also, raised, and lifted out of engagement with ratchet 105, the parts being so proportioned that pawl 115 is thus'llfted when'the ratchet has been advanced the distance of one notch. The spring-arm 114, by hearing down on pin 119, tends to keep the platen locked in normal position after the springs 84 and 85 have returned the various parts thereto, and thereby prevents an unpleasant vibration that might occur if no means but the springs 84 and 85 were pro vided for holding the parts at rest. It will thus be seen that, as the operator, grasping the handle 120, moves the lever 83 toward the right, Fig. 1, gear-wheel rotates ear 93, thereby causing the revolution of s aft 94, and, consequently, the rocking of arms 95 and .96, and the rollers carried thereby.

The arms continue thus to move until the,

, platen 103 strikes the type 34, the ribbon feeding between said type and said platen, which type, by operation of the fingerpieces 12, have been raised into place. As

the platen strikes these type, the numbers they bear are printed on the paper-ribbon .1104, after which the lever 83 is released, and

' the spring 84 returns the lever and platen to i'normal position. When the operator desires :t-o'obtain and-print the sum of the various lever .83 strikes thereupon simultaneously.

with thestriking of platen 103 on the type, thus permitting thema'jor part of the percussion to be borne by the lever and screws rather than by the platen and type, thereby helping to reduce the wear and tear on the more delicate parts of the mechanism.

The ribbons 35 and 55 are carried on reels 121, which are rotatably mounted in suitable brackets 122 projecting from and exterior to the side-plates 1. The ribbons may be fed forward by manual operation of the knurled knobs 123, which are secured to each reel, or by suitable automatic ribbonfeed mechanism, which, forming no part of the present invention, is not herein described in detail. The ribbons pass into the interior of the machine through slots 124 provided therefor in the side-plates 1.

It will be seen that the accumulating.

, mechanism is all carried between the sideplates 57, and is entirely independent of the printing mechanism. Brackets 125 are fastened to these side-plates, and secured thereto are rods 5, the construct-ion of whiclr-is herein above described. If it should, at

* any time, become necessary to make repairs on the accumulating mechanism, it may be removed in 150250 without disturbing the residue of the machine. The only members in termediate the accumulating mechanism and the sectors 8 are the -raclrbars 38, .and these are constructed with their right-hand ends, Fig. 3, of such size that they may be inserted in place underneath the addingwheels, or removed therefrom, with little difficulty. These rack-bars are grooved at 126, and the rollers 39 and 47 ride in these grooves, thereby preventing any side-swaying of the rack-bars as they travel.

In the adjustment of parts, it will, of course, be necessary to have the addingwheels 43 alining'with the type 34, so that the figures to be printed by the addingwheels will be in the same columns as'those of the'corresponding denominations printed by the type 34. Ratchet 42 and the teeth 36 on the sector 8 are, therefore," not in aline= ment, and the teeth 41 on the rack-bars 38 are set to one side, as shown in Fig. 3, rather than along the center of the bar. These teeth, accordingly, will not strike the type 34 on the sectors 8 when the parts are returned to starting position, but-will be to one side, as in Fig. 2. The rack-bars have a cut-away part 127 which gives the adding- Wheels 43 sufficient space in which to revolve. The side-plates 57, which support the accumulating mechanism, are bound together by the shafts 49 and56, by rods 128 and 129, which rods, also, support the springs 51 and by otherrods 130, and thus the accumulating mechanism is grouped by itself, in a frame comprised of the side plates 57 and various cross-connecting rods.

i In many addingmachines, there is an undesirable profusion of parts cross-connecting the different sections, makingsuch machines expensive, complex in construction, and difficult to assemble, but in the present invention the listing mechanism, accumulating mechanism, and mechanism supporting andactuating the platen are all grouped independently of each other, save for the rack-bars 38which connect the list-ingto the accumulating mechanism. Thus, each section of. the machine can be separately as-' sembled and placed in position, and, after that is done, and the simple. operation of adjusting the rack-bar is performed, themachine will be ready for use. The rackbars give a positive'm'otion to the addingwheels, while in nearly all other machines the adding mechanism is spring-actuated, which, o:t' course, makes successful and accurate operation more difficult to secure.

The operation of'the machine, in so far'as it has not already been described, is as follows: the particular digit of each denomination to be added is determined by the extent to which the proper finger-piece 12 is depressed, and the extent of such depression depends, in turn, upon the particular socket 17 of said finger-piece in which the finger of the operator is placed. As fast as each finger-piece 12 is depressed to the limit permitted with the finger placed in any particularsocket, and the sector 8 to which it is secured thereby rotated, one of-the pawls 21 locks the sector and attached parts against return movement. By the rotation of the sector, the type 34 carried thereon are raised until the proper type-face is at a point opposite the ribbon 35, and, simultaneously there- 'with, the rack-bar 38 engaging said sector isdriven forward, saidbar in turn causing the proper adding-w11eel- 43 to rotate the distance necessary to make.the type 54 which is-then left exposed to the ribbon 55 represent the sum of the number at'which the adding-wheel last stood and the new digit that has been added in. When all the necessary finger-pieces have been depressed, it is obvious that the proper type 34 which will then be in a position opposite the ribbon 35, will representthe desired number, which number may then be printed. To print the numbers, the operator moves lever 83 to the right, Fig. 1, thus causing the platen 103 to move and strike the type 34, which thereupon print their respective figures on the paper carried by the platen. The number having been printed, the lever is released, spring 84: acts thereupon'and returns. it, together with the platen, to normal position, where the platen mechanism is locked against vibration by .the bearing of spring 114 upon pin 119. Knob QO'is then turned in the direction of the arrow, Fig. 1, the pawls' 21 are thereby withdrawn from engagement with the finger-pieces 12, and springs 24 cause the sectors 8 and connected parts to fly back to the starting position. The return movement of the rack-bars 38 will not, however, affect the adding-wheels 43, as pawls 44: lock these against return movement. These operations may berepeated ad Zbz'tum, so long as there i are any numbers to be printed and addedf IIIOHOII 111 n Sa rollers belng and at each operation of the operating-lever 83 the platen is given a partial revolution .by'the action of pawl 115 on ratchet I05, toi aper ribbon forward. F inally,;

feed :the when all t e numbers'lto be addedhave been thus registered and printed, theoperatingf lever is pulled toward the left, Fig. 1, thereby bringing the platen 103 into engagement z with the type '54 of the addingwheel's 4G3; which print the sum or total of the column of items upon the paper ribbon 104. Knob 76 may, thereupon, be turned, and the machine cleared.

In cases where it may be desired merely.

to ascertain the sum of certain numbers, without printin or listing them, the various numbers may e registered in the usual manner, but the operat-ionsof the lever 83 omitted, except, possibly,the final one, which causes the sum itself to be printed. Sub;

totals may be obtained at any desired intermediate point, and the adding operation thereupon resumed, because the machine is not cleared by .;the mere printing of a total," since the clearing requires the "inde-' pendent and distinct operation hereinbefore described.
