This invention relates to tens-carry mechanism for tabulating machines or other machines in which such mechanism is required or desired.

The invention, if patented, may be manufactured and used by or for the Government of the United States for governmental purposes without the payment to me of any royalty thereon, in accordance with the provisions of the act of April 30, 1928 (ch. 460, 'i5 Stat. L. 467) s This application is a division of my applicadf tion Serial No. 286,976, iiled July 28, 1939, for Tabulating machines. So much of the illustra tions of the present case are taken from the former application as are deemed necessary to il A lustrate the tens-carry mechanism in connection with the mechanisms with which it is associated in said application.

The object of the invention is to simplify the tens-carry or transfer mechanism by combining the carry and print controls, thereby eliminating costly and troublemaking machinery, and to effect the tens-carry of all of the accumulator wheels that are ready for tens-carry, simultaneously instead of progressively.

In the drawings illustrating the invention- `Figure 1 is a sectional view taken about through the center of the rear portion of a tabulatng machine, showing a sensing means, the accumulators, the tens-carry mechanism, and a printing mechanism.

Figures 2 to 6 are fragmentary views of the transfer or tens-carry mechanism showing several diierent and progressive positions of the accumulator wheels and associated tens-carry parts.

Figures 7 to 10 are detail fragmentary top edge views of the tens-carry levers showing the various positions of certain pins and cams carried by said levers, and, i

Figure 11 is a detail view of the reset mechanism showing the zero position of the accumulator wheels and associated parts.

Figure 12 is a detail view of the pivoted bailcarrying member for resetting the print levers after a. printing operation.

The various parts of the mechanism about to be described will be indicated by the same reference characters as are employed in the parent case, so that this divisional patent, if and when issued, may be more readily connected with the parent case.

Referring to the drawings, and particularly to Figure 1, the numeral I designates the main driving shaft of the tabulating machine to which the tens-carry. mechanism about to be described is particularly appropriate. This shaft carries the large gear 2 shown in dot-and-dash lines. The ratio ef the gear to other gears and parts is such that it represents, with one revolution, four card f feed cycles. This shaft, as well as many of the pricing parts 33, 33' and 33", over which the cards pass from the feed hopper (not shown) oetween the feed rolls 8 and i0 to and between the sensing roll 53 and iced rolls mounted just below the sensing roll, and from thence over deck portion 33 to the open upper end of the card chute 29T. At each open side of the chute there are arranged a suitable number of feed rolls that iced the cards to a stacking hopper (not shown).

Below the spring-backed sensing roll 53 and extending through an opening in the deck portion 33 is the enlarged end ll of release lever N, pivoted at i5 between ears 16, there being a plu rality of these ears and also a plurality of re lease levers corresponding to the number of columns on the card to be tabulated. The rear ends of these levers are broadened as indicated at il and are engaged and rocked on their pivots i5 by spring-backed sensing fingers 63 of sensing roll 53 when the hole in the record or card is sensed. The forward ends 19 or the levers are arranged to engage the narrowed ends of the accumulator arms 8|, there being an arm for each accumulator and for each release lever.

The lower ends of the arms 8| are pivotally mounted on shaft |82, mounted in the side plates B, which plates are within the outer side plates A, the construction preferably being such that the whole unit containing the tens-carry and accumulator mechanism may be bodily removed from between the plates A. s

Loosely mounted on a stud on the accumulator arm 8| is a pinion 84', there being a pinion for each arm and each accumulator wheel 84. These accumulator wheels are loosely mounted on the shaft 82 and are constantly in mesh with said pinions, and when the release lever 'I4 releases the arms 8| the pinion of the actuated arm will be caused to mesh with the elongated actuator gear 86 which is mounted on shaft 8l in the inner side plates B. Each accumulator Wheel has rigidly secured thereto a. step read-out member 85, which comprises 4 similar arms each having ten steps which function solely in the printing operation. On the extreme end of each arm of the read-out member is a. cam point |02, which points are arranged to engage a two-point cam |03, one of which is carried on the upper edge of each print and tens-carry lever |04. `These levers are each provided at their rear ends with an elongated slot |06 which embraces the long rod |01 extending between the inner side plates A and upon which the levers are supported at their rear ends. These levers are otherwise supported at their iront ends by springs which are attached to a pawl H2, one of which is pivotally mounted at ||3 on each lever, and each pawl has a point for engagement with the teeth of the accumulator wheel of the next higher order, there being a pin |88 on each lever for engagementl with the pawl to limit its upward movement under the influence of spring 'I'he iront end of lever |04 is cut away to form a shoulder |08 and a narrow extension |09 which terminates in a downwardly extending hook ||4, the purpose of which will presently appear.

A bar spans the distance between the two inner side plates B and forms a stop for the forward ends of levers |04 until they are moved down and oiT the bar by the cam point |02 of the step read-out member 85, and urged forward by the spring until its hook ||4 momentarily rests in groove ||5 formed in the forward end of a plate ||6 pivoted at ||1 to the lower ends of levers ||8. There are two of these levers, one at each side of the machine, which are pivoted at ||9 on studs |20 on the inner sides of the side plates A. Each of said levers carries a roller |2| held in constant engagement by spring |23 with the periphery of cams |22, one on each side of the machine, and fast to shaft I. There is a spring |24 which is preferably just sufficiently strong to support the weight of the plate ||6 and to hold it in its working position, which is mainly in a horizontal direction,

There is a pin |28 (Figures 2 to 10) on each transfer lever |04 near its forward end and which cooperates with a cam 21 carried by the next higher value or adjoining lever throughout the machine; or in other words, each lever is provided with a pin on one side and a cam on the other.

The levers ||8 are actuated against the tension of springs |23, by the cam |22 on shaft This cam is formed with four high-points |25 corresponding to the four card feed cycles of the machine. The tens-carry mechanism operates between cards, and the cams |22 are so shaped as to provide suitable depressions which when engaged by rollers |2|, permit the levers ||8 to rock forward under the influence of springs |23. Between every card the levers ||8 and the plate IIB carried thereby will be rocked, whether there is a tens-carry operation or not, but when there is a tens-carry, which is at the time that cam point |02 has passed the high point |03 of the two-point cam, and depressed the forward end of the lever |04 and cleared it of the stop I I0, when hook ||4 of said lever will rest momentarily in the groove ||5 of plate ||6, as clearly shown in Figure 2. On the further movement of cam |22, as shown in Figure 3, the lever |04 will be carried further forward by reason of its engagement with the plate I6. Upon a still further movement of the cam |22, as shown in Figure 4, and when the high-point |25 is in engagement with roller |2|, the lever I I8 and its plate I6 will bring back the lever |04, and in doing so the pawl ||2 on the lever will engage a tooth on the adjoining accumulator wheel of the next higher order and advance this wheel the distance of one digit, and also cause lever |04 to be restored to the position shown in Figure 4 against the stop bar I0.

In tens-carry mechanisms of machines of this character, whenever a number is added to 9 .it must aect the next higher value accumulator wheel and thus carry one to this next; higher wheel. For instance, one of the accumulator assemblies may have reached such a position as to represent a series of the numeral 9, as shown in Figure 1, wherein it is intended to show that several of the step read-out members 85 are side by side in exactly the same position and all CII registering 9, in which position the cam points |02 have engaged the forward step of the twostep cam |03 and brought the lever half-way down on the stop bar |0, as shown in said figure. Now, as the wheel of the lower order passes from this 9" position, the tens-carry lever |04 is depressed and clears the stop bar ||0 where this tens-carry lever is in position to carry one to the next higher accumulator wheel, and in doing so the pin |28 (Figure 5) will slide over the cam |21 on the next higher order transfer lever and disengage said lever from the stop bar ||0, and in effecting this disengagement this lever in turn will operate upon the next higher order transfer lever in the same manner and so on until the tens-carry operation has been effected in the successive higher order wheels as required and as progressively illustrated in Figures 4, 5 and 6, and

in plan positions in Figures '1, 8, 9 and 10. When the accumulator wheel stands in any other position than the f9 position the pin |28 passes under the cam |21 and in no way disturbs the adjacent lever.

Referring to Figure 2, the lower order accumulator Wheel 84 has passed to 0 position and in doing so vengages the point |03 of its associated lever |04, and depresses said lever to a. point below the stop bar ||0, as shown. Meanwhile the shaded lever |04 with its associate accumulator wheel 84 is standing on 8 and in the position shown in this figure. Upon further movement of the cam |22, as shown in Figure 3, and between card sensing cycles the lever |04 under the influence of spring will move forward and allow the pin |28 to pass under the cam |21 of the shaded lever |04 or next higher order lever, which operation is shown clearly in Figures '7 and 8. On still further movement of the cam |22, as shown in Figure 4, upon the rearward movement of lever ||8, the lever |04 is brought back to stop ||0 and while moving back to this position the pawl ||2 engages the next higher order accumulator wheel 84 and advances this wheel one step.

Referring to Figure 5, the step read-out cam 85 associated with the front lever has passed from 9 to 0. The next higher order read-out cam is standing on 9 on its associated lever |04, which lever is partly depressed as shown. In the position of the cam |22, as shown in Figure 3, it has allowed the lever |l8 to be rocked forward under the influence of spring |23 and has allowed lever |04 to move forward also, and as shown in Figure 6, allowed the pin |28 on lever |04 to engage cam |21 on adjacent lever of higher order and exert a camming action between said cam and pin, thereby depressing the lever to a point below the stop bar ||0. This operation is further illustrated in Figures 9 and 10, wherein, in the former or Figure 9, the pin |26 is shown about to engage the cam. In Figure l0 the pin has reached a point where the next higher order lever has been depressed and brought to position shown in dotted lines in Figure 6, in which position the lever |04 is free to move forward as heretofore described. While all llevers which have been acted on by a tens-carry operation are being reset back on stop bar |0, each lever with its pawl ||2 will advance its adjacent accumulator wheel of higher order one step, thus carrying one to the next higher order wheel.

So far, the functions of the levers |04 have been explained in connection with the trarsfer or tens-carry operation. However, these levers also function importantly in the operation of printing the results of the tabulation, and to accomplish this, each lever is provided near its rear end with a finger |5| arranged to engage one or another of the steps on the arms of the, step read-out members 85. To start the printing operation the conventional single revolution clutch shown in my application Serial Number 286,976 is released, causing shaft |28 to make one revolution. The first movement of the shaft will bring down bail |49.

When the forward ends of such of the levers |04 as have been actuated are in the path of the downward movement of the bail |49 (Figures l and 11) which extends over all of the lever extensions |09, they will be released from the stop by the bail, and, under the influence of springs (there being a spring for each bar), will be brought forwardcausing the finger |5| of such bars as have been actuated to engage the step on the read-out member 85 appropriate to the amount stored on the accumulator wheel associated with the particular actuated bar.

As clearly shown in Figure 1, the rear-ends of the levers |04 engage one or, another of the steps |54 of the step read-out bars |53, corresponding to the amount represented by the particular step. These step read-out bars are held normally in their lowermost position by bail |6| that connects the rear ends of two pivoted bars |58 pivoted at |58 on the inner side/plates B. Each arm |58 is formed with a forwardly-extending upwardlyinclined arm |59 (Figure 1), each provided with a roller |60 constantly in engagement with cam |45 fast on shaftl |28. There are two of these cams, one on each side of the machine. The step read-out bars |53 are each provided with lateral extensions |56 upon which the bail |6| normally rests, keeping all of the b'ars normally in their lowermost or reset position against the tension of springs |51 which are attached to said extension and to a cross-bar |56 near the top of the machine.

As explained, the first movement of the cam |45 is to bring down bail |49 for engagement with the forward ends of all of the print and tens-carry levers |04 that have been actuated and at this time the fingers |5| will nd their appropriate steps of the step read-out members 85. A further movement of the cam |45 will allow the rollers |60 to drop into the low portion of the cam thereby permitting the springs |51 to rock the arms |58 positioning the bail |6| to allow the step read-out bars to find their appropriate position with respect to the location of the print and tens-carry levers |04. Any of the step read-out bars |53 that have been positioned by actuation of the leversl |04 will be raised A according to the value of the step occupied by the rear ends of said bars, and the bars in moving up will engage the swinging pendants |18 pivoted to printing sectors |12, there being a swinging pendant for each sector, and each step read-out bar. These sectors are loosely mounted on a rod |13 connecting the ends of short links |14 pivoted on studs |15, one of which is provided on each side plate A. 'Ihe sectors, each having printing characters thereon, are raised by the bars through links |18 according to the amounts represented by the steps on said bars, bringing the characters in position to make an impression on the result sheet vinterposed between said sectors and a suitable platen |11, it being understood there will be a suitable inked ribbon between the paper or result sheet and the platen.

The numeral |69 (Figure 1) represents print levers of which there are two, one at each side of the machine rockably mounted on studs |10 on the side plates A. The upper ends of these levers are connected by a push bar |1| which extends crosswise of the machine through the openings in the sectors |12 and in position to engage one or another of the notches |00 of said sectors when the bars are rocked through the movement of links |68 pivoted to the lower ends of print levers |69, as fully described and illustrated in my application herein referred to and of which this application is a division.

In the position of the parts described the mechanism is conditioned for a printing operation. After this takes place, all the partsY are reset to their normal position. There is a cam |8| on shaft |28 and in the further movement of this shaft and cam the step read-out bars |53 were reset by cam |45 and after that the high point |96 of cam |8| engages a roller |84 mounted on a spindle |84' on pivoted member |82 which member carries a bail |86 which encompasses all of the bars |04 and rocks the said-member and bail rearward into engagement with the ends of all of the levers |04 that have been actuated, thereby resetting them to their normal position with their shoulders |08 against the high point ||0' (Figure ll) of step ||0, which position is the iirst position after the machine is entirely reset.

The member |82 is centrally located in the machine and is pivoted at |83 to a suitable support.` It is bifurcated for the passage of the bar |95 which is pivoted at its forward end at |03 to an ear |82 integral with said member and has in its rear end an opening for the passage of a stud |85' on the lower end of lever |81. This lever is fastened on a rod |88 mounted in the side plates B. Near each end of this rod is rigidly attached a bent lever |89 (Figure 11) in the upper end of each of which is pivoted a comb holder 9|. These holders carry a comb |92 that extends substantially for the entire width of the machine, there being a comb tooth for each step read-out member 85 and accordingly, for each accumulator wheel. Each comb holder |9| carries a roller |93 which work-s in angular cam slot |94 formed in each of two plates |95, one of which is secured to each side plate B. Upon the still further movement of cam |8| and the rocking of the bracket |82 the shaft |88 will be rocked and the bent levers |89 will also be rocked forward and will bring a tooth of the. comb |92 into contact with the under side of any arm of the step read-out member 85 that is not standing in reset position and reset said members and their associated accumulator wheels to zero position, or that position shown in Figure 11.

Between each card cycle, the accumulator mechanism is reset to its normal position or that in which all of the accumulator arms 8| are in the position shownin Figure 1, wherein their upper ends 80 are latched against the ends of the release levers 14. After the accumulator wheels have been actuated, it is necessary to reset all of the accumulator arms 8| and for this purpose cams 90 (one oneach side of the machine and shown in shaded lines in Figure l) are provided and are rigidly mounted on shaft These cams cooperate with levers 9|, also shown in Figure 1, which are pivotally mounted on studs on the side plates A, there being one of these levers mounted on each side of the machine. These levers carry a roller 92 in constant engagement with the cam 90 and held in such engagement by springs 93. The upper ends of the levers at each side of the machine are.

pivotally connected with resetting arms 94 whose rear ends are connected by a bail 95 extending across all of the actuating arms 8|, the bail being arranged to engage and reset all of the arms 8i when the rollers 92 engage the high points' 96 of cams 90, between each card feed cycle.
