Fig'. 22 is a sectional rear view showing sevei'al trains in the total- 6 5 izer, which trains will be hereinafter designated as carrying-trains. Fig. 23 is a detail diagrammatic view illusti'ating iiiy improved carrying' mechanism.

The machine shown in the accompanying' 7o drawings is of that type wherein the items ai'e set up on a keyboard, the keys of which cooperate with stops to adjust control-bars in one of nine different positions, depending' upon the location of the key struck. The keys before operating a control-bar cause a segmental gear on the said bar to engagea ti'ain which is connected to and opei'ates printing and indicating wheels. Before this ti'ain is restored to normal position the segmental 8O gear is disengaged therefrom and a totalizei' may be thrown into engagement with the itemwheels, whereby the restoration of said itemwheels operates to place the item in the totalizer. The totalizer is composed of sevei'al 35 carrying-trains and may be engaged with the item-wlieels to drive the latter' to exhibit the total of items accumulated in the totalizcr. The item-wheels ai'e self-clearing. The totalizer may be cleared or returned to zero at will.

In the following description I have employed headings, under which will be found appropriate references to the pai'ts identified with the respective headings. 9 5

lVhile I have shown but one form of my invention in the accompanying drawings, it is obvious that many minor changes in the construction, arrangement, and combination of the several parts can be made and substituted for those herein' shown and described without in the least departing from the nature and principle of my invention.

T/L@ keg/oawThe keyboard (see Figs. 1 and 9 to 12) consists of a number of longitudinal series of keys running from l to 9,7 said keys having usual button heads and shanks, the latter being guided vertically by plates 4 and 8. These plates are carried by posts 2, rising from the base-framing' of the machine. Cross-tie bars 3 connect the upper ends of the forward posts and support the forward edge of plate 4, while cross frames or bars 7 are arranged between said posts, to the lower edges of which are secured the plate 8. Plates 4 and 8 are providedwith suitable openings 5 and 9, respectively, through which pass and are guided the keyshanks.

10 represents springs connected to the plate 4 and to pins 11 on the key-Shanks for elevating said shanks. As usual, the keys are independently operable, and each series of keys has a control-bar common to it whereby the depression of any key of a series will actuate the bar common to that series in such manner that said bar will be moved to one of nine different positions, depending upon the relative location of the key struck. These controlbars, as I have termed them, (indicated at 14 in the drawings,) are pivoted upon a shaft 13, mounted in the side frames 12 at the back of the machine, said bars being spaced apart by washers 15. Each bar is held in an elevated position by a spring' 16, and each bar carries at its rear end a segmental gear extension 17. These bars 14 have rearwardly-inclined slots 18 in their upper edges opposite 4the key-Shanks, which at this point carry pivoted blocks 19, designed to engage iiXed abutments, in this instance the plate 4, to arrest the upward movement of the key-Shanks. Blocks 19 carry projections or pins 2O at their lower ends in vertical alinement with the open ends of the inclined slots 18, whereby when any key is depressed bar 14 is swung on its pivot until arrested at the limit of its designed movement by adjustable stops 21, having heads 22 in the path of the pins 20. By referring to Fig. 1 it will be observed that the adjustable heads have shouldered projections 22 on their upper ends, which in the operation of the device are designed to cooperate with the pins 20, said pins riding down the inner side faces of their cooperating projections 22. The purpose of this is to hold the pin 2O firmly in its slot 18 when the key is depressed, and in this manner lock the control-bar to the depressed key; otherwise the sudden depression of the key might result in the overthrow of the controlbar due to the momentum gathered in its downward movement. From this it will be seen that the control-bar is forced downward by the pin 2O on the gravitating block engaging the bottom of its inclined slot 18, and before the pin 20' is stopped in its downward movement it passes along the inner face of the projection 22, and thus prevents the gravit-ating block from rocking in one direction, the walls of the slot 18 preventing the block from rocking in the other direction, and so the control-bar is locked to the keyshank and is prevented from moving past the designed position. Blocks 19 being pivotally mounted on the key-Shanks will, when the keys to which they are pivoted are depressed, swing on their pivots by reason of the inclination of the slots 18. Thus the key has an initial downward movement or vertical play during the travel of pin 2O in slot 18, and the bar 14 is not moved until the pin reaches the bottom of the slot.

The rear cross-bar 7 affords stops 23 for horizontally-sliding bars 24, arranged in j uxtaposition to the key-Shanks and on the opposite side thereof with respect to the coperating control-bar 14. These bars 24 have reduced portions 25 at their rear ends, provided with collars 48 and pins 50. (See Fig. 8.) Bifurcated arms 47 on a rock-shaft 44 bear against the rear faces of collars 48, being yieldingly held thereagainst by means of a spring connected thereto and to the pins 50. ln this manner the rearward movement of the bars 24 will positively rock the shaft 44 in one direction, while the forward or return movement of said bars is effected by the means which yieldingly return the shaft 44 to its normal or home position.

It will be noted that the rock-shaft 40 is common to all of the bars 24 aud that when any one of said bars is operated to rock said shaft the springs which connect the bifurcated arms 47 with the normal bars 24 are placed under tension. Thus if any other bar 24 is subsequently operated its connected spring will tend to draw the same rearwardly.

I have before referred to an initial idle movement of the keys, and it is during this movement that the bars 24, common to the series in which the operated key is located, is moved rearwardly to rock the shaft 44.

Located under pins 29, projecting from the key-Shanks, are escapement-dogs 26, pivoted to the bars 24 at 27. The front edges of these escapement-dogs are provided with cam-faces y28, 28, and 28, the first mentioned being in the nature of a beveled Lipper end. The initial downward movement of the key-shank (see Fig. 12) will cause its pin 29 to strike the beveled edge 28 of the escapement-dog located immediately therebeneath (see Fig. 12a) and move the bar 24 rearwardly, (see Fig. 121),) because the lower end of the escapement-pawl carries a pin 31, operating between two pins 30, projecting from the lower edge of the bar 24,

IOO

and said pin 31 is in contact with the foremost of said pins 30. The cam-face 28n is disposed vertically, so that when the pin rides down over this cam-face the bar 24 will be held in a stationary position by reason of the vertical movement of the pin. (See Fig'. 12.) Th en the pin passes onto the cam-face 28b below the pivot 27, as shown in Fig. 12C, the dog will be rocked and the face 28h disposed vertically, so that a continued downward movement of the pin results merely in so rocking the dog and holding the bar 24 rearwardly. The pin 31 will now engage the rearmost pin 30, placing a spring 32, connected to pin 31 and to a pin 33 on the bar 24, under tension, which tension is directed to pulling the lower end of dog 26 forwardly. The lower end of dog 26 is provided with a stepped shoulder 35, opening rearwardly, and as the pin 29 passes beneath the lower end of the dog it is received upon a projection 36, and the spring draws the lower end of the dog over the pin 29, as shown by dotted lines in Fig. 121. The projection 36 is substantially L-shaped, and the forward face of its horizontal member lies in the vertical plane of the cam-face 28b when the pin 29 is riding thereon, and consequently the pin 29 easily passes from the cam-face of the dog onto the fixed support 36. This insures the bar 24 being held rearwardly until the key reaches its lowermost position, in which the dog is released, and when the key rises the pin 29 is permitted to pass above the projection 36 and behind the dog, as shown in Fig. 12d, allowing the bar 24 to be returned to its normal or forward position before the controlbar 14 is released. By this construction it will be noted that the keys do not remain down after being' pressed, that the rock-shaft 44 is first operated through the bar 24 before the control-bar is moved, and that after vthe depression of the control-bar the bars 24 are released and the rock-shaft 44 is in readiness to return to its home position before the control-bars can be restored. Briefly stated, the keys by contacting with their respective stops determine the position of the control-bars and the throw of their connected segmental gears 17, while the bars 24 effect an engagement between the segmental gears and the item recording and indicating mechanism, whereby the said mechanism is in position to be operated by the segmental gears before the latter are actuated, and said mechanism may be disengaged from said segmental gears immediatel y upon the completion of the movement of the said gears in one direction, (the forward.) The item mechanism referred to is normally out of mesh with the segmental gears.

Verme for eject/ag m engagement between t/w 15cm accordi/ng (md aiderait/ing mechanism cmd z/e coai'oZ-/CWS.38 indicates a pivotshaft mounted in suitable bearings in the frame-plates 12, upon which shaft is arranged.

a swinging' frame composed of the side framepieces 39, which are spaced apart by suitable tie-bolts. Spring 40 (see Fig'. 11) is connected to the swinging frame 21 to hold the same normally in an elevated position. An adjustable fixed stop 41, coperating with a projection 42 on the swinging frame, limits the upward movement of said frame.

43 indicates a pin or projection extending laterally from one of the frame-plates 39, being received in a slot 46 in an arm 45, fixed to the rock-shaft 44. Thus when the rockshaft 44 is rocked by any of the bars 24 the item mechanism carried by this swinging frame is caused to primarily engage the segmental gears by reason of the depression of said Swinging' frame through the instrumentalities just above mentioned.

tem-Zr/ucrs.-51 indicates a shaft carried by the swinging' frame-plates 39, upon which are arranged what I term groups of driving mechanisms common to each segmental gear 17, s aid mechanisms being provided with means whereby they yieldingly drive the item mechanism, and when a total is being' taken said item-driving' wheels serve as yielding' intermediate gears. (See Fig'. 8.)

52 indicates a pinion loosely mounted on the shaft 51, which pinion is designed to mesh with the segmental gear 17 when the latter is in its rearmost position, (before it is moved by the control-bar.) This pinion has a gear 53 conjoined thereto. Gear 53 is fixed to a sleeve 54, mounted upon the shaft 51, upon which sleeve is loosely mounted a gear 55, said gear being' connected with the sleeve by a torsionspring 57, carried in a drum 56. ln this manner the gear 55 may be rotated independently with respect to the primary gear 53, the torsion-spring' tending' at all times to restore the gear 55 to its normal relation to the driving or primary gear 53. This relation between these two gears i-s established by means of a pin 58, extending inwardly from the face of primary gear 53 in the path of a pin 59 on the gear 55. y(See Figs. 13 and 14.)

indicates a centering-wheel, in appearance resembling a stai', which is conjoined to the secondary gear 55. (See F ig'. 15.)

61 indicates a centering-pawl coperating with the V-shaped notches in the centeringdisk 60. This pawl is mounted on a shaft 62, which has a bearing in the frame-plates 12, suitable washers or sleeves being employed to properly space the centering-pawls apart. (See Figs. 5 and 8.)

63 indicates a rod carrying springs 64, connected to tailpieces on the centering-pawls to hold them yielding'ly against the centeringdisks 60. 65 indicates a stop-bar coperating with the said tailpieces for relieving the centering-disks of undue friction. (See Fig. 8.)

38 and spaced apart by appropriate washers oiusleeves 67, so as to be constantly in mesh with the secondary gears 55.

68 and 69 are pins projecting from the faces of the gears 66 and in whose path are located pins 70, fixed in the shaft 38, said pins protruding through circumferential slots 71 in the sleeves 67. (See Fig. 3.) These pins normally engage the pins 68 and aline the gears 66. The pins 7 0 cooperate with the pins 69 for the purpose of restoring the wheels 66 to normal position after they have been operated in placing an item in the itein-wlieels. The restoration of the gears 66 is effected by a backward rotation of the shaft 38, which is produced by mechanism hereinafter referred to. The pins 69 are circumferentially staggered on the wheels 66, so as to form a spiral series, whereby no two adjacent wheels will be started back at the same time. This results in successive restorations of the gears 66, commencing with the mechanism identified with the column vof lowest orders. 4Thus the carrying is effected in the different groups of mechanisms in successively-iiicreasing orders.

72 indicates shafts mounted in fraiiieplates 12 and upon which are arranged transmittingpinions 73, in mesh, respectively,with the several gears 66.

-Y 74 indicates gears mounted upon shafts 38, with which mesh pinions 7 5 on the shafts 72, whereby1 the item indicating and recording` devices may be grouped close together. (See Figs. 2 and 5.) These trains of gearing from the gears 66 to gears 74 are identified with the 'several columns and are independently operable, 4being' controlled by the different series of keys.

76 indicates a shaft preferably supported in one of the frame-plates l2 above the shaft 38, and upon which shaft 76 are gears 77, meshing, respectively, with the gears 74.

78 indicates a shaftupon which are mounted gears 79, meshing, respectively, with the gears 77. These gears 79 have type-wheels conjoined thereto, said wheels carrying on their peripheries printing characters from 1 to 9 and also 0, the latter normally occupying a position in the priiiting-line.

I have not shown in this application any type-hammers or means for taking an impression from the type in the printing-liiie; but it is my intention to use some approved construction for printing and recording items and totals from these printing-wheels.

81 indicates ashaft upon which are arranged gears meshing, respectively, with the gears 77, and to which gears 82 are conjoined indicating-disks 83, forming sight-wheels for the operator. (See Fig. 8.) These sight-wheels indicate the amount of each item registered, and toeffect this they areprovided with niiv. a merals from i) to 9, inclusive, on their peripheries.

There the machine is used to register, re-

cord, and add the amounts indicating sums of money, such as at piesent current in the United States, the dimes and cents wheels are preferably separated from the units dollar-wheel in lieu of printing the decimal-point.

[ivm-m 1c/mn ma Incl: 84 indicates ratchetwlieels conjoined to the several gears 7 7, respectively, with which ratchets cooperate pawls 86, mounted iixedly upon a shaft 85. Shaft 85 extends outwardly beyond the frame 12 on one side of the machine, where it cai'- ries a depending rock-arm 87.

88 indicates a rock-arm extending upwardly from the outer end of shaft 38. A pin 89 on the upper end of'arni 88 engages the arm 87, which rocks the shaft 85 to di sengage the pawls from their ratchets whenever the arm 88 moves rearwardly.

90 indicates a pin on a downward extension of arni 88, which pin lits in slot 92 in the end of rock-arm 93, fixed to the shaft 44.

Shaft 85 is provided with apin 166, to which is connected a spring 165, having its other end connected to a pin 167, fixed in the frameplate 12, (see Fig. 51.) whereby the pawls 86 are normally held in engagement with the ratcliets 84.

By the above construction all of the wheels 77 are released whenever any of the bars 24 is in other than a honie position.

Resto/ving HL@ f/Lcm.-zindcctng and type fui/aafla- -93 indicates a stud-shaft in one of the frame-plates 12, upon which is mounted a segmental gear 94, meshing with a pinion 95, arranged upon the outer end of shaft 38. (See Figs. 1" and 2.) A spring 96 holds this segmental gear in an elevated position. y depressing this segment shaft 38 is rotated, so as to cause its pins 7 O to pick up gears 66 by engaging their pins 69 and return said gears and their trains connected therewith to a norinal position.

97 indicates a handle on the gear 94, by which said gear may be operated. This gear 94 is also operable by a lever 98, whose hub portion is mounted upon the stud-sliaft 93. The segmental gear 94 is provided with a pin or projection 99 for cooperating with the lever-liandle 98. Operatingthe handle 97 independently of lever-handle 98 will cause the type and indicating wheels to be returned to Zero position without placing' the items in the accumulating or totalizing mechanism. Thus the item mechanism may be cleared in the event that a mistake is made, and therefore the handle 97 might properly be termed a correction-liaiidle.

ricami/Mating zf/u; fm/is fri/nf t/m tot/liscia- By depressing the lever-handle 98 the segmental gear 94 is not only operated to restore the gears 66 through their pins 69, but the return movement of said gears being exactly proportional to their advance is utilized in driving the totaliZing-gears. A condition precedent to the restoration of the gears 66 through the segmental gear 94 to place the items in IOO IIOV

the totalizer is the engagement of the totaliZer-wheels with the gears 66 through the primary gears 53, coupled to the secondary gears 55. In order to effect this engagement before the gears 66 start on their return movement, the lever-handle 98 is notched in line with the projection 99, so that its initial movement will be utilized in effecting the aforesaid engagement prior tothe commencement of the return or backward movement of said wheels. This is accomplished by means of a cam-notch 101 in the hub 100 of lever 98, in which notch rests the projection 157 of a lever pivoted at 156, whose other member, 1 55, is provided with a cam-face for cooperating with a pin 158 on the swinging' totaliZer-frame 104. (See Fig. 1.) This frame is pivoted in bearing-plates 105` and when the projection 157 is in the notch 101 the totalizer is out of engagement with its drivers. Vhen the lever 98 is depressed ,the frame 104 is rocked forward to engag'e the totalizer with its drivers, after which the lever 98 restores the gears 66 and places the item theretofore set up therein in the totalizer. This is accomplished by the gear 66 in its backward rotation backwardly rotating the gear 55, and through the medium of the spring the gear 53 is also caused to rotate and by rotating the pinion 110 set up the item in the connected totalizer-train. This reverse rotation of gear 66 and its driven train effects the restoration to Zero of said itemtrain and its connected parts and at the same time sets up the item in the totalizer-train, leaving' the item in the totaliZer-train when the gear 53 is thrown out of mesh with its pinion 110.

To hold the rocking frame 39 in an elevated position and prevent engagement between pinions 52 and the segmental gears 17 during this operation of placing the item in the totalizer, I provide an adjustable projection 158L on the frame 104, which is designed in the forward position of the frame to occupy a position under projection 159 on the frame 39. Likewise when the frame 39 is depressed to engage the pinions 52 with the segmental gears 17 the projection 159 is located in the path of the projection 158 and prevents the frame 104 from being rocked forward to engage the totaliZer-wheels with the primary gears 53.

153 indicates a stop on frame 104, which cooperates with adjustable stops 152 and 154 to limit the rocking movement of said frame.

Carri/11g zio arl/210022.25 raul/)2s of Mg/zer 0r- (Zuz106 indicates tie-bolts in the upper ends of frame-plates 104, which bolts or rods carry downwardly-eXtending plates 107.

108 indicates a shaft journaled in the lower ends of the plates 107. (See Fig. 22.) These plates, in addition to supporting the shaft 108, form division-walls for groups of gearing, corresponding in position to the drivinggroups on shaft 51.

109 indicates sleeves on one of the shafts 106 for spacing the plates 107. and 22.)

Each group or train of wheels on the shaft 108 comprises a pinion 110, in alinement with the primary gear 53.

Referring now to Figs-16 to 21, inclusive, 111 is a disk conjoined to pinion 110, said disk having preferably ten radially-disposed slots 112 in its periphery. 113 indicates a companion disk, preferably provided with ten angularly-arranged slots 114 in its periphery. In the normal position of these disks the outer ends of the slots 112 and 114 register'. This registration is normally established by means of a spring 114, whose ends are connected to the disks, respectively. A pin 111Ll on disk 111 cooperates with a pin 113 on the companion disk to insure registration of the slots. 115 indicates a pawl pivoted to the inner face of disk 111, the free or inner end of which carries a pin 116, passing through an opening 117 in the companion disk, beyond which it cooperates with a notched disk 120, said lastnamed disk being preferably provided with ten V-shaped notches `121. 118 is an extension of the pawl 115, which cooperates with a pin 119 on the disk 113, which pin holds the pawl in engagement with notched disk 120 and locks-said disk 120 to the disks 111 and 113. 122 is a notched disk conjoined to the disk 120, both of said disks being fixed to a sleeve 123, which carries a gear 124 at its opposite end. 125 is a centering or star-shaped disk, with which cooperates a pawl 126, pivoted on a shaft 127.

From the above it will be seen that the disks 111, 113, 120, and 122, and the gear-wheel 124 are all locked together by the pawl 115 and rotated collectively. However, when the disk 113 is rotated independently, so as to relieve the pawl 115 from the restraint of pin 119, permitting the pawl to ride over the disk 120, said disk 120 and its connected centering-disk 122 and gear 124 are free to turn.

128 indicates a shaft mounted in thc frame 104, preferably below the shaft 108, and upon which are a series of sleeves 129, each of said sleeves carrying a cam-disk 130 and a gearwheel 131, the former being preferably immediately under the notched disk 122, and the latter'in mesh with the gear 124 of the next adjacent train of lower order. The cam-disk is provided with a groove 132 in its side face, which groove is essentially concentric, save fox` a fluctuation 133. This cam-disk also carries a radial projection 134, which is designed to cooperate with and advance the distance of one step the disk 122 upon each revolution of the cam-disk. This advance of disk 122 dis- (See Figs. 8

places the pin 116 and causes it to enter a notch 121 in the rear of the one it formerly occupied. This circumferential displacement of disk 120 is only possible when the disk 113 is circumferentiall y displaced to carry the pin 119 away from the projection 118 on pawl 115 to release IOO IIO

siaidpawl. rIhis displacement of disk 113 is effected by means of a bell-crank lever pivoted on a shaft 115,mounted in the frame-plates 104. This bell-crank lever consists of a member 136, carrying a pin 137, which rides in cam-groove 132, a hub portion in the form of a sleeve 138, and a member 139, carrying a pin 140, designed to simultaneously enter the slots 112 and 114 whenever the member 136 is caused to dip by its pin entering the fluctuation in the cam-groove. (See Fig. 7.) The dipping` motion of the bell-crank lever, the displace ment of the disk 113, and the consequent release of the pawl are practically coincident with the engagement between the projection 134 on the cam-disk and the notched disk 122, which notched disk is rotated one-tenth of a revolution. As soon as pin 116 is seated in its newly-found notch and as soon as the bellcrank lever passes beyond the fluctuation in the cam-groove thedisk 113 will be released from its displaced position, and the spring 114L will restore said disk to lock the pawl and incidentall)7 the disks and gears 111, 113, 120, 122, and 124 until they shall have made another revolution or rather nine-tenths of a revolution, the last tenth being' devoted tothe operations above described.

In Fig. 23 I have illustrated diagrammatically the carrying mechanism, and in order that the operation of the parts may be understood I will briefly describe the construction shown in this ligure. The segment 17 is shown in mesh with the gear 52 on the shaft 51; but it will be understood that in ordinary operation when the gear 53, conjoined to the gear 52, is in mesh with the gear 110 on shaft 108 the segment 17 is out of mesh with the gear 52. I have shown segment 17 in the figure merely for the sake of locating' it with relation to the gear 52. I have not shown the companion transmitting-gear 55, as the same would obscure the view. Assuming that motion is transmitted through gear 53 to the gear 110, the notched disks will be rotated as long as the pin 119 engages the pawl 115, so as to lock'the pin 116 of said pawl into one of the recesses of the disk 120, the disks 111, 113, 120, 122, and the gear 124 will be locked together and driven by the gear 53. These elements are in this way conjointly moved to register items, as controlled by the devices before described, such movements being in tenths of a revolution. The gear 124, before referred to, meshes with the gear 131 on the shaft 128, which gear 131 is mounted on a sleeve 129, the opposite end of said sleeve carrying the cam 130, located under the disk 122 of the next adjacent train of higher order. Gam 130 carries a projection 134, designed to engage in the notches of the disk 122 and drive said disk, and consequently the next adjacent train of higher order, the distance of one-tenth of a revolution for every complete revolution of the cam 130. In this manner cam 130 is driven by a train of lower order, and whenever said train of lower order is moved a complete revolution the notched disk 122 in the next adjacent train of higher order is moved one-tenth of a revolution, and the carrying from one train to the next is thus effected. In order to arrest the train of higher order, or rather one part of it, so as to effect a movement of the disk 122 relative to the stationary part, the bell-crank lever, composed of the arms 136 and 139, is brought into action, the position of said lever being controlled by the cam-groove in the cam. The arrows on the several disks and gears indicate their designed direction of movement in the-registration of items, and it will be seen that the projection 134 is just leaving the notched disk 122, in which event the roller on member 136 of the bell-crank lever will ride in the concentric portion of the cam-groove for nine-tenths of a revolution or until the projection 134 is again in position to engage and drive the disk 122. The cam shown in this ligure (23) is driven by the train of lower order, the gear 124 identilied with which is shown on the near end of the shaft 108. Then the projection 134 is in position to engage the disk 122, the fluctuation in the cam-groove is so located that the next tenth of a revolution of the driving-train of lower order will cause the bell-crank leverA to rock, placing the pin 140 in the notches or recesses of the disks 111 and 113. Inward movement of arm 139 accomplishes the following: Disk 111 is arrested, and though at the time of its arrest it may be receiving motion through the transmitting-gear 53 it will be remembered that there is a yielding connection between gears 55 and 53, which permits of the arrest of this disk 111, the motion being' absorbed by the spring' between gears 53 and 55, and upon the release of disk 111 said disk is driven by the spring to the desired extent. However, we will assume that for the purposes of this description disk 111 has been arrested. The inward movement of pin 140 circumferentially displaces disk 113 with respect to disk 111, so as to carry the pin 119 away from the projection 118 of the pawl 115, and thus the pawl lies passive, its pin 116 merely resting by its own weight, if the disks are in proper position, in one of the notches of the disk 120. At least disk 120 and its conjoined disk 122 are free to move when driven by the projection 134. Projection 134 can only drive disk 122 coincidently with the rocking or dipping movement of the bell-crank lever, and consequently the pawl 115 is unlocked only when disk 122 is receiving motion from the cam projection. The instant that the driving action between the cam projection 134 and the disk 122 has been completed the bell-crank lever leaves the fluctuation in the cam-groove and raises the pin 140 out of the disks 111 and 113, said disks now being restored to normal position by their restoring-spring, before de- IIO scribed, so that the train is locked until the cam has again been rotated nine-tenths of a revolution by the gear 124 identified with the train of lower order.

Should it happen that in restoring the wheels 66, which transmit the item through the gears 55 53 110, &c., the gear 110 should be temporarily locked by its conjoined disk 111 being arrested by the pin 140, (in the act of carrying from one train to the neXt,) it will be obvious that the spring 57, between and connecting the gears 55 53, Will yield and store up the movementimparted by gears 66 until the gears 53 and 110 are released. Upon such release the spring will cause said gears to rotate at such speed as to catch up to the positively-driven gear 55.

Tft/ring a total and @Zea/ring the 250ml/2671.` From what has been said above it is evident that the printing and indicating wheels are cleared or returned to zero when the item is placed in the totalizer. Repeated operations of the machine will cause the items to accumulate in the totalizer, and in machines of this character it is desirable to operate the printing and indicating wheels so that they will print and exhibit the total of the items accumulated in the totalizer and also to clear the totaliZer or return it to Zero. To effect this, I provide sleeves 141 on the shaft 128, which sleeves have slots 142, through which project pins 143, fixed on the shaft 128. (See Fig. 4.) The cam-disks 130 are provided with recesses 144 and pins 145. The pins 143 are normally out of the paths of the pins 145, so that the cam-disks maybe rotated without interruption. r1`he cam-disks and their associate parts, as well as the sleeves 141, are held against longitudinal movement by the frameplates 104; but the shaft 128 is longitudinally movable, being held in its normal position, wherein the'pins 143 are out of the paths of the pins 145, by means of a spring 147 bearing against a head 146. (See Figs. 2 and 5.)

148 indicates a crank-handle iixed to the opposite protruding end of Shaft 128, the inner end of the staff of which is provided with a cam-surface 149, operating against a fixed projection 150. (See Fig 2a.) By this construction the shaft 128 is longitudinally displaced (or drawn to the right) as it is rotated, such longitudinal displacement locating the pins 143 in the paths of the pins 145 of all of the cam-disks which have been operated. The rotation of shaft 128 thus drives the camdisks and gears 131 and their respective trains on the shaft 108 backward, and through the connected intermediate gears rotating forwardly the total will be indicated on the disks 83 and will also appear in the printingline o`n the wheels 80. It will be obvious that the shaft 128 operates the respective type-wheels a distance corresponding to the backward movement of each of the respective cam-disks 130. When the cam-disks reach their initial or home position, they are arrested.

In transmitting the total as contained in the totalizer through the several trains to the printing and indicating wheels means must be provided for releasing the gears 77. Such is shown in Fig. 1, wherein the frame-plate 104 of the totalizer is provided with a projection 162, which when the frame-plate is in a forward position strikes one member of a bell-crank lever 160, pivoted at 161, whose other member is connected by a link 163 to a projection 164 on the hub of the rock-arm 8T. This rock-arm, it will be remembered, is fixed to the shaft 85, which carries the locking'- pawls 86.

Pawls 86, as before stated, are normally held against ratchets 84 by a spring 165, (see Fig. 5,) one end of which is attached to a pin 166 on shaft 85 and the opposite end to a pin 167 on plate 12. This spring serves to hold the bell-crank lever againstthe projection 162, and consequently assists the spring 151 in withdrawing the totalizer from engagement with its driving-gears 53.

In taking a total the lever 98 is first depressed to engage the indicating and printing wheels with the totalizer, after which the crank-handle 148 is operated to return the totalizer to Zero and place the total in the indicating and printing disks. If the handle 148 is returned home while the trains are in mesh, the total will be placed back in the totalizer and the indicating and printing wheels cleared. If it is desired to clear the totalizer, the handle 148 is operated to restore the totalizer to Zero while it is out of mesh with the indicating and printing wheels.
