abled at one or more points when desired, and the totalizer could then be used for adding in a plurality of columns. It has also been proposed to construct a totalizer settable at will into a condition such that, when the totalizer was moved into engagement with its actuators, a certain group of its wheels would be held back out of engagement, but without disabling the transfer. The wheels thus restrained were not affected by the difierential movements of the actuators, but were available to register amounts transferred to them from wheels of lower order. Machines equipped with such totalizers as above referred to can be set up by the operator so as to adapt them for different uses. It is an object of the present invention to improve not only the means for splitting a wide totalizer, but also the means for disabling portions of it altogether, leaving the actuators for the disabled wheels available for other uses. This is especially useful in instances where said actuators are also associated with, or themselves constitute, type carriers, and particularly where said type carriers bear alphabetic or other types in addition to numerals. Thus, actuators associated with the totalizer or with some part thereof. may be used at one time for adding and at another time actuators associated with disabled totalizer wheels may be used for printing text including alphabetic text or other designatory matter while still using a portion of the totalizer for computing. To provide for this flexibility of use is one of the objects of the invention.

Another object of the invention is to render the totalizer more certain to operate correctly in a respect which will be pointed out.

To the above and other ends which will be apparent from the following specification, the invention consists of certain features of construc tion and combinations and arrangements of parts, all or which will be fully described herein and particularly pointed out in the claims.

In the specific instance illustrated in the drawings, the invention is shown embodied in a punched card tabulating machine of the sort described and claimed in the application for Letters Patent for Tabulating and accounting machines, filed November 13, 1937, by W. W. Lasker, Jr., executor of the will of W. W. Lasker, deceased, and J. Mueller, S. N. 174,354; in the corresponding British patent of Remington Rand Inc., for Statistical machine, No. 522,562, accepted June 20, 1940; and in the application for patent for Tabulating and accounting machine, filed February 1, 1940, by J. Mueller, S. N. 316,739. Except as hereinafter explained, the machine fragmentarily illustrated and described herein, may be as described in said patent and applications.

As shown generally in Fig. 1, the machine comprises a base section 30, and mounted on it a head section 3|. The base section is constructed substantially as described in the patent to W. W. Lasker, No. 2,044,119, dated June 16, 1936, and is the same as has been in use in Powers tabulators for a number of years. Punched cards are fed from a hopper 32, by picker 33 and feed rolls 34,

' and they rest on a flanged cross bar 65.

into a sensing chamber in the base of an upper pin box 35, from which they pass into a receptacle 36. The sensing pins 31 are in a lower pin box 38 which is reciprocated by eccentrics 48 on the motor driven main base shaft 4|. They elevate set pins 42 in the upper pin box 35, and through them operate Bowden wires 43 in a translator 44. In the head section 3|, the Bowden wires 43 displace code or "permutation bars 45 which, in turn, control stops 46 for arresting the combined type carriers and totalizer actuators 41. The latter are guided on rods 48, are moved upward against the stops 46 by springs (not shown), and are moved down to normal position by a restoring bar 58. As far as the present invention is concerned, the actuators 41 may be reciprocated and'controlled by any suitable means. The head section has a rear drive shaft and a front drive shaft 52, geared to rotate at the same speed as the main base shaft 4|. The restoring bar 50 is reciprocated by cranks, one on each end of the shaft 5|, which cranks drive pitmans 53 (Fig. 3) with a motion modified by certain guide discs in a manner not necessary here to be explained.

In the machine of the prior disclosures, there is a long continuous seriesof the actuators 41, each of which carries a series of types 59, including both numeric and alphabetic types (Fig. 11). A number of totalizers may be placed in front of said actuators in two tiers, mounted on two dove-tail shaped frame bars 54 and 55; and the construction is such that a totalizer may be a link 68 with a bell-crank transfer pawl 10, pivoted at 1| to the left hand face of the next lever 68 to the right, (Fig. 8) and cooperating in ausual way with a transfer tooth 12 on the wheel 56 on that lever. When said wheel turns from 9 to 0, said tooth rocks the pawl counterclockwise, withdrawing the dog 66 and permitting the left hand lever 60 to rise at its rear mounted in any desired position on either of said bars so as to be actuated by any desired succession of the actuators. In the assembly of each individual machine, totalizers are so mounted in number and location appropriate to the use to which the particular machine is'to be put. The totalizer illustrated in the drawings is adapted to this situation, though the invention, as to most of its features, is applicable to other machines. The specific totalizer illustrated will be described in detail.

The totalizer may be of a width greater than is likely to be needed for a single number, and p it is so constructed that it can be split at a desired point or points, so as to divide it in effect into a plurality of totalizers, each comprising whatever number of register wheels is required by the work. As shown, and preferably the totalizer can be split, by the operator of the machine, at any point in its width he desires. The drawings were made from a totalizer of a width of forty denominations. The totalizer wheels 56 (Fig. 6) are each journaled on a bearing 51 riveted to the left hand face of a sheet metal lever 60 which, with certain differences to be described, resembles levers contained in the totalizers of the prior disclosures. In Fig. 6 the section is taken on the left face of one of these levers, and the wheel 56 and cooperating parts guided in upper and lower comb bars 63 and 64,

When the wheels 56 are in mesh with the racks 41, the levers 60 are individually spring urged to swing upward at their rear ends. .Each lever is normally held down by a transfer dog 66 engaging a shoulder of the lever. The dog 66 is urged into engagement by a spring 61, and is connected by end. 'The wheel 56 on said left hand lever is thus moved individually along its actuator 41 (lengthwise of said actuator) a distance to turn said wheel one tooth, when said lever is arrested by a shoulder 13 thereof striking the comb bar 63. Each wheel 56 is held, when out of mesh, by a detent lever 14 pivoted to the lever 68 at 15, and urged against the teeth of the wheel by a spring 16. As thus far described, the register wheels, their levers 60 and the transfer and detent devices, are all substantially the same as the upper set of such devices in the totalizer of the prior disclosures. The transfer dogs 66 are pivoted on a rod 11 seated in a comb bar 18.

The comb bar 6| is a part of a frame which swings rearward and back to move the wheels 56 into and out of mesh with the racks. Said frame may be variously constructed. As shown, its principal member consists of a round rod (Figs. 6, 9 and 10) having a longitudinal cutout with one radial wall against which a flange of the bar 6| is secured by screws 8|. At its ends it has eccentric trunnions 82 jourialled in bearings in the staationary base casting 83 of the totalizer unit, said bearings including journal caps 19. The flange on the bar 6| extends only the length of the thick portion of the member 80, the ends of said bar projecting a little beyond the base member 83. The member 83 is detachably and adjustably secured to the dovetail shaped bar 54 or 55 in about the same manner as in the prior disclosures, viz., by a dovetail undercut fitting the-rear edge of the bar and clips 19 screwed tight against the forward edge of the bar.

The frame of the totalizer proper comprises right and left hand frame plates 84 (Figs. 5, 8 and 10) which plates are rigidly connected by the cross bars 63, 65, and 18. The bar 65 is supported at its ends by brackets 85 secured to the plates 84, and the comb 64 is supported from the bar 65 through a bar 86. Said bar 86 and the comb 18 are made fairly heavy for stifiness on account of the width of the totalizer. Near their front ends the frame plates 84 occupy the extreme right and left end slots of the comb bar 6| (Figs. 9 and 10). Each has a stud .81 pivoted in the groove of said bar and retained in place by a clip 88 secured by a screw to the end of the-bar 6|. The rear ends of the frame plates 84 are supported by links 90 pivoted thereto and to the base casting 83. The whole construction is such that when the member 80 is rocked clockwise as viewed in the drawings, the totalizer, including the levers 60 and the framework in which they are guided, moves as a whole rearward until the wheels are properly meshed with the racks. The motion is limited by stop plates 92, one screwed to each side of the base 83, arresting lugs 93 depending from the frame plates 84. The totalizer is moved to its forward position by springs 94 (Fig. 5).

'I'he rocker comprising the bar 6| and shaft 88 also includes at each end a plate-like lever 95 which '(Figs. 9 and 10) is secured by a screw 96 against the end of the trunnion 82 and which has a fork embracing the end of the bar 6 so that the lever and said bar are keyed together to rock in unison. Each lever 95 has a forwardly directed arm which is connected by an upright link 91 to a lever 98, pivoted on a transverse shaft 99 supported by the frame plates 84. The rear arms of the levers 98 are connected into a bail by a rod I which overlies the forward ends of the detent levers I4. When the rocker is rocked clockwise to engage the totalizer wheels with the racks, the rod I00 depresses the forward arms of said detents and lifts them out of the wheels. A similar construction was described in the prior disclosures.

As in the Mueller application, S. N. 316,739, two levers IOI pivoted to the outer faces of the frame lates 84, are connected by a bail bar I02 overlying the levers 60, each lever IOI being urged clockwise by a spring I03 and'having an arm underlying the bail bar I00. When the totalizer is shifted rearward to mesh the wheels, and the bar I00 descends, the bar I02 is raised away from the levers 60, leaving them free to swing upward in case of transfer. When the wheels move out of mesh and the bar I00 rises, the springs I03 depress the bar I02, to assure that any elevated lever 60 is returned to normal.

Spring pressure is applied to the totalizer levers B0 to move their rear ends upward to transfer the tens, in the same manner as in the prior disclosures. Each of said levers forward of its pivot 62 has pivoted thereto at I04 a bellcrank I05 which is urged clockwise (Fig. 6) by a spring I06 connected to an arm of the bell-crank and to the end of the lever 80, the motion bein limited by a lug I01 formed off from said lever. A roller I08 at the forward end of the bell-crank, underlies a channel bar IIO secured to a cross bar III. There are two of these cross bars, one for the upper and the other for the lower tier of totalizers, and they are connected together at their ends into a rigid rectangle by vertical bars IIZ (Fig. 2). Each of the bars H2 is pivotaliy mounted on two parallel rock arms or levers I I3, pivoted at II4 to the right and left hand main frame pieces II5, respectively, of the head section of the machine. The lower lever I I3 of each pair carries a follower roller H6 bearing against a cam III. on the front drive shaft 52, against which earns the parts are held by springs H8. The cams are so designed as to depress the bars III just after the totalizer wheels have been engaged with the racks and to allow them to rise, deenergizing the springs I06 in time to permit any operated levers 60 to drop down to normal position when the wheels are out of mesh with the racks.

In the prior disclosures the bell-cranks I05 were on the upper ones of two sets of levers like the levers 60, so that the rollers I08 bore against the under surface of the bars III themselves. The present levers 60 occupy vertically about the position of the former lower set, and the members IIO are inserted to take up the space thus created between the followers I08 and the bars III. It is contemplated that it may in some instances be desired to employ both the present adding totalizers and also the former adding and subtracting totalizers side by side in the same machine. It is, therefore, preferable that the member I it) be only long enough to cover the followers I08 of the present totalizer (to the number of forty in the specific instance described) leaving the bars III otherwise in condition for use with the former totalizers.

The totalizers are moved into and out of engagement with their actuators by the rocking of two shafts, viz., a. shaft I20 for the upper tier and a shaft I2I for the lower tier of totalizers. these shafts and the means for operating them and for controlling their operation being identical with those of the prior disclosures. One of the levers (Fig. 5) (the right hand one, as illustrated) has a link I22 pivoted thereto at I23, said link being pivoted at I24 to a lever I25 fast on a stub shaft I28 Journaled in a boss at the base casting 83. The lever I25 is operated by a link consisting of a rear section I21 and a front section I28, said sections slidably connected together by slots and headed pins I30 and by stifl springs I3I tending to maintain the compound link at its maximum length. In case a totalizer wheel tooth collides with a tooth of the actuator, the link can yield, stretching the springs I3| instead of injuring the mechanism. An arm I32 fast on the rock shaft I20 or I2I has a stud I33 playing in a closed slot I34 in the forward part of the link. When the shaft I20 is rocked clockwise, or the shaft IZI counter-clockwise, the stud I33 acting on the link I28, I21 rocks the lever I25 which, through link I22, rocks the rocker 95, 80, BI clockwise, moving the totalizer rearward until arrested by the stops 32 thus bringing the wheels into mesh with the racks (Fig. 4). The parts are so designed that in this movement the radius I26, I24 of the lever I25, and the axis I24, I23 of the link I22, have the action of a toggle, acting on the lever 95 with an increasing leverage and a decelerated velocity, so that the totalizer is brought to its engaged position with a sufficiently powerful pressure and is brought to rest gently without too much jar. In its final position the toggle lacks enough of being dead centered to assure that the springs 94 can restore the parts when the arms I32 return to their forward positions.

In order to provide for disabling the totalizer in its entirety when desired, the slot I34 is made of such length that the stud I33 can move idly in it without operating the link, and the surplus length is covered by a displaceable interponent. As here shown said interponent consists of a sheet metal piece I35. pivoted at I36 to the link section I28 and, when in active position, having its front end covering a portion of the slot I34 and lying in the path of the head of the stud I33 and communicating the motion of said stud to the link, as shown in Fig. 4 and in the lower totalizer in Fig. 5. The interponent I35 can, however, be swung by hand to the position shown in the upper totalizer of Fig. 5, where it is out of the path of said stud. In the setting illustrated in Fig. 5 when the shafts I20 and I2I are rocked. the lower totalizer will be brought into engagement and not the upper. The interponent is infinenced by a spring I31 so disposed that it tends to retain said interponent in either of its positions, which positions are defined by two arms I38 of said interponent being arrested by the pin I39 to which the spring is connected.

In operating the adding and subtracting totalizer of the prior disclosures, arms similar to the arms I32 had the double duty of first reversing the totalizer from one sign to the other, on occa sion, and then moving the totalizer into engagement, so that said arms have a longer stroke than is required for the present totalizer, which accounts for the 10st motion between the stud I33 and the interponent I35 indicated in Fig. 5. In another machine such lost motion would, of course, not be necessary.

In order to provide for splitting the totalizer at any desired point or points and for disabling any desired denominational elements of it, means are provided whereby a lever 66 may be set bodily forward of its normal position relative to other such levers, and secured there, thus displacing the wheel 55 on said'lever away from its actuator 41. In the instance illustrated, each lever 66 is provided with two studs 62 (Figs. 6 and 9) one behind the other, the forward stud resting in the notch in the bar 6| when the element is in use. The forward end of the lever may be lifted by hand and the lever be drawn toward the front of the machine and the rear stud seated in the notch as shown in the middle one of the three levers in Fig. 9. This locates that totalizer wheel 55 so far forwardthat it does not engage its rack 47 when the bar BI is swung rearward, thus leaving that rack and type carrying bar entirely free for other use such as to print either alphabetic characters or numbers not to be added.

In order to prevent accidental displacement of the studs 62 from the bar 6i, a locking flap or ball I46 (Fig. 6) is provided, having at its ends ears pivoted on the cross rod 69 and urged by a spring MI counter-clockwise to its locking position where it is arrested by ears I82 (Fig. 8) striking the front edges of the frame plates 84 The lower edge of this bail stands just above the upper edges of the levers 65. When it is desired to change the setting of one of these levers, the bail I46 is swung by hand clockwise out of the way.

may be located at any desired positions, and all other positions of the totalifier may be disabled entirely, the Wheels never engagingthe actuators. The bars 67 coordinated with these wheels may, therefore, be utilized for printing any desired numbers or text or for adding on another totalizer on the other bar 5 8 or 55. If the unused wheels were permitted to engage the actuators, such printing would cause a hodge-podge of numbers to be rolled into them, resulting in the printing of meaningless totals. Also, the spacing of the types on the type bar is only half that of the rack teeth, and alphabet types are interspersed between the numeral types, as shown in Fig. 11. When, for example, a bar 41 is set to print an E,"

a tooth of the rack stands directly behind a tooth of the totalizer wheel 55, and if it were sought to move said wheelinto engagement, the teeth When a lever to is set forward in its disabled position, it rocks clockwise the transfer dog 65 which engages it. The link 68 for this dog is connected with the transfer pawl ill of the next lower order, and which may still be in active condition. In order to permit of this swinging of the dog 66 without disturbing its pawl I6, said dog is connected with its link 68 by pin and slot, the pin moving to the forward end of the slot when the dog is swung as described.

In order to prevent swinging movement of a lever 56 which has been disabled as above described, each such lever has a finger I 33 made at its under rear portion, and projecting forward in such position that, when the lever is set inactive said finger comes under the flange on the frame bar 55, as shown in Fig. 9, and locks the rear end of the lever down.

The setting of a lever 60 to its forward position to produce a split between two sections of the totalizer, acting through link 58, unlatches the dog 66 for the next lever 60 to the left. The pawl I0 then rests on a stud 69 on lever 50, to prevent said pawl from dropping down. Said lever 60 then becomes the units lever of the left hand section, and it will not be required to rise for transferring. In order to lock this units lever down, the following means are provided (Figs. 6, '7, 8, and 9). Near its rear end, each lever 60 has an ear I44 projecting from its right hand face, and an ear I45 from its left hand face, said ears so disposed that when one of the levers is set to its forward inactive position, its ear I45 lies on top of the ear I44 of the next lever 60 to the left. As the inactive lever is locked down at M3, its ear I45 locks down the units lever at its left. This is illustrated in Fig. 9 and also in Fig. 7 where the third lever from the left has been drawn forward, bringing its ear I65 into the plane on which the section is taken.

Within the range of the, say forty places, of the totalizer, adding columns of any desired width would collide. This is obviated by setting the wheelback as described, so that it never engages the rack. Any desired denominations of the totalizer may be temporarily put out of use in the manner described.

A further improvement in the totalizer resides in the provision of a lock to assure that the levers 66 do not rise in total taking operations, In total taking, the wheels 56 are in engagement with the racks 31 on the up-strokes of the latter, and each said wheel and rack is arrested by the transfer lever being struck on its abrupt edge by the transfer tooth 72 on the wheel. It has been found in practice that in rapid operation, the vibration set up by this blow may occasionally jar the dog 66 loose from the. shoulder on the lever 60, allowing the latter to rise, thus causing the type carrying rack to move upward too far. In order to make this misoperation impossible even at high speed, a bail bar I46 (Figs. 4, 5, 6, and 8) normally stands as shown in Fig. 6 with its lower edge just back of the upper edges of all of the levers 66; but in total cycles this bar is swung forward so as to stand above said levers and positively to, prevent them from rising as shown in Fi 4. Said bar I 86 may have at its ends arms I 41 formed oif therefrom and pivoted at I 48 to ears formed on from a frame plate I50. The latter is here shown fastened to the frame and comb bar 63, which, in this wide totalizer, it serves to stiffen and strengthen.

The means for controlling the locking bar I46 would vary in detail in difierent machines. In the present instance, the left-hand arm I41 is prolonged downward and is connected by a link I5I with a bell-crank I52, conveniently pivoted on the cross shaft 99. Fig. 5 shows a pair of totalizers one above the other, and the bellcranks I52 of the two totalizers are connected to rock in unison by a vertical link I53. The machine includes certain parts that are set in distinctive positions for total taking, and one of them, viz., the so-called credit balance shaft I54 is utilized in the present instance to operate the locking bail bars M5. As explained in detail in the prior disclosures, this shaft is rocked clockwise in Fig. 5 early in the blank stroke preceding a total stroke. and is held so rocked throughout the blank stroke and until the latter part of the total or grand total cycle, when it rocks back to its normal position. An arm I 55 is mounted fast on this shaft and is connected by a link I56 with the lower bell-crank I52 so as to rock the latter counter-clockwise when shaft I54 is rocked as shown in Fig. 4. This operates the lower locking bail I66 through its link I5I, and, through the link I53, upper bell-crank I52 and link I5I, it

operates the upper locking bar I46, maintaining all of the levers 60 locked down during the total taking operation.

As shown in Fig. 6, the link I56 is connected with the lower bell-crank I52 by pin and slot I51 so as to allow the movement of the lower totalizer into and out of engagement with the racks without rocking the bell-crank. At its forward end said link I56 is connected with the arm I55 by pin and slot and spring I58, the spring tending to hold the pin in the rear end of the slot. The motion of the arm I55 is at least sufficient, when taking a total from the upper totalizer, to take up the lost motion at I51 and to operate the locks I46. When taking a total from the lower totalizer, as shown in Fig. 4, there is an excess of motion of the arm I55, which stretches the spring I58.

The mechanism of the invention may be modified in detail and it can be applied or adapted to various machines without departing from the invention. The cooperating mechanism of the particular machine which is fragmentarily illus trated in the drawings is fully described in the prior disclosures, but it may be worth while to describe some of it briefly herein.

Fig. 2 is a sectional elevation taken just inside the right hand frame member H5, and showing some of the mechanism at the right hand part of the machine. The total taking control unit I60 contains two cam shafts, one set into rotation to take a total (two cycles) and the other to take a grand total (three cycles). The cams rock counter-clockwise several levers I6I, pivoted on a post I62. Among these is one which, through one of several links I63, operates bell-crank I64, link I65, lever I66, link I61, and arm I68 fast on the credit balance shaft I54, which, as above described, it was found convenient to utilize to throw in the locking bails I46 (Fig. 6). This shaft is pulled" at the beginning of each total taking operation (early in the blank cycle preceding a total cycle) and is held pulled until near the end of the total taking operation.

The so-called total shaft I10, Fig. 2, is pulled (rocked counter-clockwise) just before a total cycle by another of the levers I6I acting through one of the links I63, a lever I1I, link I12, one of a plurality of bell-cranks I13, link I14, and arm I15, the latter fast on shaft I10. This shaft performs several functions, one of which will be described briefly.

The grand total shaft I16 is similarly pulled with similar results, just before a grand total cycle, by a lever I6I, link I63, lever I11, link I18, a bell-crank I13, a short link hidden by link I14, and an arm I80 fast on the shaft.

The mechanism for rocking the shafts I20 and I2I to move the totalizers into and out of engagement, is partially shown in Fig. 3, which is a view from the right of parts on the outer side of the left hand frame member II5, the web of said member being sectioned away. Fast on the lower shaft I2I is a lever or arm I8I urged by a spring I82 clockwise against a fixed post I83. The arm I8I is made of two plates connected together by a pin I84 on which, between the plates, four devices are pivoted. Reference number I85 designates a bifurcated link or coupler, the fork of which embraces a pin I86 on the upper end of a follower lever I81 pivoted loosely on a fixed post I88 and drawn clockwiseby a spring I90, against a total taking cam l9I on the front drive shaft 52. The forked coupler I85 is urged counter-clockwise by a spring I92, which presses the lower tine of the fork against the underside of the pin I86 and holds the upper tine away from said pin. Said upper tine has a ratchet-shaped tooth which is normally out of engagement with the pin I86, but can be moved into engagement by depressing the coupler. The cam I9I swings the lever I81 rightward at the mid-part and leftward at the latter part of each cycle. The total shaft I10 is pulled in the latter part of the blank cycle and, through link I88, pin, slot, and spring connection I93 and bell-crank I84, depresses coupler I85, by means of a roller I85 on said bellcrank. Lever I81, when swung leftward will then act to rock the shaft I2I counter-clockwise, moving the lower totalizers into engagement to take a total as hereinbefore described.

Addition on the lower totalizers is controlled by a second lever like lever I81 and just behind it in Fig. 3. The add cam which operates this lever gives the timing appropriate to addition. Pivoted on pin I84 is a second coupler similar to the coupler I86, but its tooth for cooperation with the pin like I86, is on the lower tine of the fork and is, therefore, normally in engagement. The total shaft depresses it out of engagement by a bell-crank like I94.

The upper shaft I20 has fast thereon an arm I96 rocked counter-clockwise by a spring I61 against the post I83. This arm has pivoted thereto two couplers similar to those on arm I8I, and operated, respectively, by two follower levers 200, both pivoted on the post I88 and drawn by springs 20I leftward in Fig. 3 to press their follower rollers 202 against the rear faces of add and total cams, respectively, on the shaft 52. The levers 200 are positively rocked clockwise by their cams, and the couplers like I85 differ from the latter in acting as pull links instead of push links. Two bell-cranks I94 (there are four of these in all) are connected by links to arms fast on the grand total shaft I16. Th add coupler is normally active, but is depressed out of engagement and the grand total coupler is depressed into engagement by the rocking of the grand total shaft I16.

While I have described what I consider to be a highly desirable embodiment of my invention, it is obvious that many changes in form could be made without departing from the invention, and I, therefore, do not limit myself to the exact form herein shown and described, nor to anything less than the whole of my invention as hereinbefore set forth, and as hereinafter claimed.

What I claim as new and desire to secure by Letters Patent is:

1. In a totalizer in which the transfer of the tens is effected by moving a totalizer wheel along its actuator relatively to other wheels, a totalizer wheel support settable relative to other wheel supports away from the actuator, so as to disable the wheel on said support by preventing it from engaging its actuator, and means for concomitantly locking the support so set against transfer movement.

2. In a totalizer in which the transfer of the tens is effected by moving a totalizer wheel along its actuator relatively to other wheels, a totalizer wheel support settable relative to other wheel supports away from the actuator, so as to disable the wheel on said support by preventing it from engaging its actuator, means for concomitantly locking the support so set against transfer movement, and means also acting concomitantly to lock against transfer movement the wheel support of next higher order.

3. In a totalizer in which the transfer of the tens is effected by moving a totalizer wheel along its actuator relatively to other wheels, a totalizer wheel support settable relatively to other wheel supports away from the actuator, so as to disable the wheel on said support by preventing it from engaging its actuator, and means acting concomitantly to lock against transfer movement the wheel support of next higher order.

a. In a totalizer, a series of totalizer wheels, individual supports for said wheels each pivotally movable to sweep its wheel along the associate actuator to transfer the tens,means for sustain ing said supports for said pivotal movement, and means whereby each of said supports and wheels is individually settable at the point of pivotal support away from its actuator, disabling any wheel so set and making its actuator free to be operated without turning said wheel while leaving other wheels operable both to the right and to the left of the wheel or wheels so set.

5. In a totalizer of the kind in which the totalizer wheels are mounted on individual supports each actuated to move its wheel along its associate wheel actuator to transfer the tens, a wheel support in the form of a lever having two pivots at different distances from the actuator and settable to either pivot at will, the wheel on said lever being engageable with its actuator in one setting and not in the other. 6. Totalizer wheels each mounted on a lever' which swing the wheel along the rack to transfer, each said lever being individually settable in asaaeao,

the totalizer frame in a direction away from the actuator so as to keep that particular wheel out of mesh when other wheels engage their actuators, a tooth on said lever moved by such displacement into engagement with a tooth on the frame to lock the lever against transfer movement, and a tooth on the lever moved by such displacement over a tooth on the lever of next higher order to lock said higher order lever against transfer movement.

7. In a totalizer in which the totalizer Wheels are moved along their actuators to transfer the struction whereby one or more individual levers may be set at will to an inactive position such that the wheel or wheels mounted thereon cannot engage their respective actuators, and a lug on one lever and a lug on the next lever of lower order, the latter said lug when its lever is set inactive engaging the former and locking the former lever against transfer movement.
