' ent, 9th January, 1904, N 0. 339,477,) of which the following is a specification.

This invention has for its object to provide a totalizer' in which the totalizing units, wheels, or disks, are movable with certain operating means, or with certain car- -rying forward parts but which totalizing parts are only movable with such said parts, that is, in the usual for acquired momentum of the totalizing parts to cause them to be moved. In a way it is for producing a positive locking of the parts exceptwhen properly actuated from the aforesaid parts, thus obviating the use of spring detaining fingers, as commonly used. in the art...

In the two embodiments of our invention as hereinafter illustrated and described; we have shown sufficient parts of a totalizer necessary to a complete understanding of our invention. These parts are adapted for use in that type of apparatus shown in the U. S. Patent to Jules Frydmane, No. 738,670, of September 8, 1903.

Referring to the modification shown in Figs. 1 to 27, and particularly to Figs. 1, 3, and 16, in the side plates 0, G, of theapparatus, we mount a cam shaft N provided with a pinion P adapted to be revolved during each operation of the machine. This shaft is tain rocking levers to automatically move the total izer wheels into two positions, one the position of ---Fig. 1, where toothed totalizcr wheels are engagcd 'with suitable stop means (stationary stop 8 and toothed segments e), and the second position that of Fig. 16, where the toothed totalizcr wheels engage the composing wheels and are free from all stop means, ail as hereinafter described. The shaft N also carries a number of sets of cams, two in each set It and l, each pair of cams adapted to act'to lock or operate a provided with cams Q and R adapted to engage ccrdevice hereinafter referred to as an anchor h. The pairs of cams for the units, tens, etc., may to advantage be so secured to the shaft N as to cause their recessed surfaces for the operation of the anchors, to

come successively into operation so that units will first be transferred to tens, then tensto hundreds, etc. The direction of rotation of these cams and shaft N is indicated by the arrows. Above the cam shaft we mount a carriage formed of transverse rods, 0, a, secured in the side plates 0, G, and carrying cheek plates 11, b. t In the cheek plates a, b, We mount ashaft f, ashaft e, and a guide rod g. The-shaft f carries above the cams Q, R, a. freely rocking arm (1 (Figs. 16 & 17) carryinga helicoidal flange r at one end adapted to shift the shaft 6 as hereinafter described, and two cam levers qhp, engaging the cams Q, R, (see Figs. 6 and 17). Beneath every totalizer wheel, save that of the highest value, we freely mount upon the shaft fan anchor h (Fig. 15) adapted to be rocked by the cams k l for 20 which purpose it is provided with legs 71, j, its upper part is provided with a recess or adapted to engage with a hooked end it of a pawl g which is pivoted to the toothed segment e now to be described. The toothed segment c (Fig. 13) is also freely mounted upon the shaft f and is provided with gear teeth e upon itscrown, while at its rear a projection f is located containing an upper and a lower detent recess. The pawl 9 (Fig. 14) which is pivoted to the toothed segment is provided at its rear with a spring pressed detent adapted to enter such recess in the projection of the segment to hold the pawl in one of two positions. These positions are determined by a spring pressed lever 0 mounted upon a shaft 71 also mounted within the cheek plates 11, b, and in turn the lever 0 is operated by a certain transfer disk of the totalizer wheels to be hereinafter described. When the lever 0 is depressed, the detent of the pawl g engages the lower recess of the projection f, and is raised into the upper position dnly by a movement of the anchor to be hereinaftcr described. Across the machine in the cheek plates a, b, we locate a stationary governing grooved bar M with which a hooked end 0 of the pawl g may engage, when it is free to do so, owing to the detent being in the upper recess of the projection j. The

15 shaft h is longitin'linz'tlly slidable in its supports and car riesa pawl to engaging a ratchct'r (Figs. 1, 2, and 3) on the shaft 6. The pawl 10 is preferably wider than the ratchet 21 so that the shaft e maybe slid to aslight extent independently of the shaft hand yet not disengage the two. The shaft 9, which carries LlLL totalizer wheels, is mounted in plates 1', s, (Fig. l) slidable upon the guide rod g, and secured to and sliding with the shaft 71-. One end of the shaft. 0 passes through a hub on the plate 3, the lower part of which hub on its exterior, is grooved so that the helicoidal flange r of the shifting lqver (1' may fit it. A pin a on the shaft abuts against. and normally rests within a recess in the end of the hub, which recess is in the form of a pocket with one sloping and one straight side (Fig. Within the center of the hub is a chamber containing a spring t normally acting to bear upon a shoulder of the shaft e, to hold it, with the stud or pin it, in. the recess (Figs. 1 and 16). The extreme end of ti. shaft where it passes through the cheek plate [1, is formed with an opening 2: for the reception of the lacy (Fig. 26'). In the side frame G of the apparatus opposite the opening a, we provide an opening g normally closed by a plate secured to a lever z mounted at b in the frame and maintained by a spring a in a position against a pin 0 secured in the shifting levero." and passing through a slot in the plate b. An operating arm or handle uextending outside the machine is secured to the lever z to move it away from the opening y to admit the key, at the same time moving the pin a an extraordinary distance to compress the spring t and free the pin a from its pocket, for the purpose of resetting, as hereinafter set forth. The totalizing wheels themselves consist of hubs i freely mounted upon the shaft a, one nex the other; the hubs have an enlarged inner chamber provided with a pin p projecting part way into it. The shaft 0 has a number of pins q, in the position of. Fig. 26, located in the path of the pins p, but in all other positions free of such pins. Upon each hub we mount a toothed wheel 7; and a numbered dis]: or ring j; also a transfer disk or collar I having a number of recesses m, and one extra long transfer tooth n. The tooth '11, is adapted to engage the lever 0, before described (Fig. 23). Upon the guide rod y, we provide stationary stops 3 and s one to engage the lowest value wheel, and one the highest, when the highest value wheel is not engaged by the toothed segment which transfers to it, and when the lowest value wheel is not engaged by its composing wheel. The composing wheels are herein shown as of the same construction and operation as shown in the before mentioned patent. They turn in the direction of the arrow. They are represented as S, T, U, V,- W, and are provided with teeth *0. Normally these wheels occupy a position free of the toothed 'totalizer wheels k, to one side of them so that upon the sidewise motion of thewheels 7: the two will be interlocked Fig. 16. It will be noted that in this modification there is one less composing wheel than totalizing wheels (Fig. 3), whereby a number greater by onefigure as a result of addition by several operations may be indicated by the totalizer. The highest totalizing wheel is in engagement with the stop t only when the composing wheels are being operated.

in operation, as many composing wheels as required are rotated that distance required to produce the number one desires to totalize, as will be understood upon reference to the before mentioned patent. Then the cam shaft N is given a complete revolution. effect of the shaft N is to move the wheels is from the position of Fig. l to that of Fig. 16 by means of the shifting lever d, which through its helicoidal flange r moves the hub of the plate s, the shaft e and every thing carried thereon to the left, disengaging the segments e from the wheels k, and engaging the composing wheels with their respective totalizer wheels is, the lowest value wheel disengaging the stop s and the highest value wheel engaging the stop t The com posing wheels are now caused to return to their initial position, each rotating its totalizing wheel a proper distance, in no case more than a whole revolution. The long transfer tooth a of the transfer collar 1 will either not reach the lever 0 or as in its normal position (Fig. 20) it will reach and pass it, according to the prior position of the tooth n and the extent of subsequent rotation of the collar Z. if it does not strike the lever 0, (Fig. 21) no effect is produced upon the detent held pawl 9 but if it does strike the lever 0, said lever in turn strikes the dog or pawl g depressingit to cause the detent to pass from the upper to the lower recess in the projection f 1 of the segment and to lift the nose 0 out of the grooved rod M (see Fig. 23). Prior to the time of depression of the pawl whether the pawl is to be depressed or not, the cams Z and k act to throw the anchor into the position shown in Fig. 21, 2'. 6., with the recess m in position to receive the tail or hook it of the pawl g should it be depressed, as in Fig. 23. After the operation of the detent carrying pawl g by the long tooth n through the lever 0, when a number is to bevcarried forward, (Fig. 17) the cams Q, R, come into play to return the helicoidal flange-r (Fig. 1.7) to cause the parts to be moved from the position of Fig. 16 to that of Fig. 1, that is, to disengage the, composing wheels from the totalizer wheels and cause said totalizer wheels to engage with the segments of the next, higher number to permit the carrying forward-of the tens. 1f the pawl, lever o, and tooth n, over any particular anchor, had not been operated but had been left in the upperdetent and recessed position that anchoridly oscillates into the position of Fig. 22, but if any particular pawl has been thrown,

then Fig. 24 illustrates what occurs, in which the anchor recess m grips the tooth n of the pawl and pulls pawl. and segment into the position shown, to move the. totalizer, wheel of the next higher number one tenth of a revolution. The parts remain in such po sition (that of Fig. 24) until the next operation, that is, until the totalizer wheels have been removed from the influence of the segmentsandmoved into the control of the composing wheels again.

At the beginning of a fresh operation the anchor, pawl, and sector are first moved into the position of Fig. 25 (in view of the configuration of the cams) from the normal position in Fig. 20 and the nose o is stopped by the grooved. rod M immediately after the anchor is moved intothe position of Figs. 18 and 1 9. This is caused by the bevel end of recess m of the anchor which forces the pawlupward to cause its detent to engage the upper recess, and its nose 0 to again grip the grooved bar M. The machine is then in condition for a repetition of the totalizing operation hereinbefore described.

To reset the apparatus at zero, (Figs. 26 and 27) we v first inove handle it in a direction to uncover the open I ing y, and to also. move the shifting lever d by contact of the pin c, with the handle a, in a direction contrary to that in which it is automatically moved by said lever d to shift the wheels clear of the segments and stationary stops (see Fig. 26). We then insert a key and turn the key and shaft in the direction of the arrow, which has the following effectst-lt forces the pin up'the incline of the hub, to compress the spring t and draw the studs q into line with the pins p on the exterior of the hubs, so that upon a complete revolution of the key and shaft, all pins p'will he engaged by the pins q and the wheels. Ic'returned to zero, whereupon the pin a will drop into the pocket of the hub 'and the-pinswithdrawn fromengagement with each other. Tl1e 'key will then be removed and the parts restored.

The modification illustrated in Figs. 28.51, inclu-' sive, is our preferred form of apparatus. It will be seen from the following description that this modification is very similar in principle and operation to the first described form. There is, however, one main feature of difference, and that is, that in the device disclosed in the first modification it is at the beginning of a fresh operation that the mechanism is set for such operation, while in the preferred form at the end of a completed revolution the mechanism is left in condition for a fresh operation, or in the normal position. This feature is primarily due to the outline of the cams Q R which through the intermediate mechanism shift the totalizing wheels from the normal position (Fig. 28) to the engaging position (Fig. 39), then to the carrying forward position (Fig. 41) and back to the normal position, all in one operation as will now be fully described in detail. Another important structural difference lies in the locking mechanism for positively engaging and locking the totalizing wheels at all times except during the resetting operation, to prevent fraudulent turning of the wheels. Minor structural differences will be noted in the carrying forward mechanism, all of which are clearly shown in the detail figures of this modification and hereinafter describedf. It consists (Figs. 28, 30, or 31) of the frame plates. 0 G and cam shaft N, a pair of side plates a b carrying a shaft f" for the carryingforward mechanism and totalizer wheel shifter, a shaft 0 for the totalizer wheels and setting disk, a stop shaft g guide shafts h g", a shaft d, the pawl locking rod and levers and a grooved rod M The cam shaft has three different sets of cams. Cams Q, R together act upon the rollers 10, q of the shifting lever d, which is mounted on the shaft f Cams Z m act together on rollers j k of levers i on shaft d which carry a rod 71?", at their ends, which rod is adapted to lock the pawls in position, as hereinafter described. Cams l, k" are secured on the cam shaft N one pair for each carrying-forward mechanism so located as to perform their carrying forward functions successively, first units, then tens, etc. Each set of cams l, in, acts upon the legs j, i, of an anchor h. (Figs. 38,- 43, and 49.) The shaft f carries the shifting lever d provided with helicoidal flange (r Figs. 41 & 42) engaging a slot in the hub S of the shaft e. to shift the hub, shaft, and wheels into the following positions: Position of Fig.28 which is the normal position with the wheels locked by the fixed stops; position of Fig. 39 with the wheels engaged with the composing wheels or operating means for adding a number; and position of 41 with some of the wheels engaged by the toothed segments and some with fixed stops during the operation of carrying forward a nurn her. The anchors h are also freely pivotcdg Uni-the shaft f they are provided with a surface on the are of a circle with a shaft as a center, interrupted by an opening or mouth m, for the reception of a'hook n of the pawl g, which is pivoted on the toothed segment e,

atf The pawl 9 also has a hook o adapted to lie against or toengage with the groffve of the rod M or the surface of the rodM, and a pin h adapted for co-operation with the 'wheel is The segment e is loosely mounted on the shaft f The projecting finger t) is also fastened to the shaftfl for a purpose to .be hereinafter described. Plates rl, .d" and-a hub i that when the wheels k" are shifted from the position I plate S serve to hold the totalizer wheels in position on the shaft 0', and they are themselves guided on rods g, h". The shaft 0' is capable of a limited motion relative to the totalizers secured by the compression of the spring t within the hub S Each totalizer wheel k" is comprised of gear teeth, a hub i, and numeral band or collar j an interior chamber provided with'a pin p a pin '0 on its outside and a groove a at b'. The stop rod (1 carries stationary stops 0' (Fig. 32) each fast to the rod and provided with noses p to take into the respective wheels k The stop for the unit wheel is broad enough to engage the unit wheel when in normal position of Fig. 28, and also in the position for carrying forward of Fig. 41. The stops forthe tens and hundreds are of a width to engage in a normal inoperative position (Fig. 28) while the stops for the balance of the wheels for which there are no corresponding composing wheels, are each provided with two teeth, one engaged when in normal position, and the other in position. of Fig. 39 (or composing position). The resetting mechanism comprises a disk 71, keyed on the shaft 0*, which is formed with a cam groove opening into a slot in the disk in which a pin s' of a lever r fast on the shaft; q engages. The end of the shaft e is formed at 17 for the reception of a key, a pawl W engaging teeth '0 on the shaft 0" prevents it from rotating in the wrong direction. The

shaft 0 is provided with pins q which in setting position only are adapted for contact with the-pins p of the wheels k A pinu on the shaft a normally occupies a pocket on the end of the hub S shown this device as provided with but three composing wheels S, T and u Their operation may be that of the patent herein mentioned.

In operation, the composing wheels are first actuated the amount desired, the cam shaft N is then turned by any suitable means such as shown in our prior patent mentioned to cause cams Q, E", to throw the lever d and flange r, to move the totalizing wheels k from the position of Fig. 28 to that of Fig. 39, thereby bringing each wheel into mesh with a composing wheel, or-where no composing wheel occnrs into mesh with one teeth of one of the fixed stops 0' posing wheels are then rotated to rotate the totalizing wheels and add the numbers. lt will be noted of Fig. '28 to that of Fig. 39, that the pins h were caused to enter the groove a of the wheels k The cams Q, R then shift the parts on the shaft 4: into position of Fig. 41, thereby engaging the totalizing Wheels from the composing wheels yet still remaining in engagement with the carrying forward means. If the wheel has been rotated to such an extent that a carrying forward should be effected, (Fig. 41) the opening 6 will cause the pin If to pass below the wheel k and ride on its periphery, Fig. 47 and force the nose n of the dog, into the mouth 'm of the anchor 71. To permit this, the cams 1 m first reshaft f We have.

The com-' pawls, for as the pawls rock, their noses 0 bear upon the raised portion 9 of the grooved rod M". This rocking of the segment, asbefore described in the first modification, serves to perform the carrying forward Fig. 48. The cams Q R now return the parts to the normal position of Fig. 28 and the anchors are rocked back into' normal starting position Fig. 43. Before this rocking has taken place, it will be seen that all the segments have been moved free of the groove of wheel k the dogs not already engaged by the segments dropping upon the curved surface of the anchor until the anchors mouth m is immediately below the nose 'n of the pawl; Fig. 46 immediately the cams Z m throw the rod n to lock the pawls in position in the groove of the bar M at the same time releasing them from the anchors grip. The apparatus is then in condition for a repetition of the operation just described. To reset this device, we insert a key on the key way ro and rotate the shaft 6 causing the pin It to be displaced as shown in Fig. 50, which compresses the spring t and moves the pins (1 into position to act upon the pins b of the wheels lct. The stud S is now released from the deep slot, and the cam disk 1:?" rotated with the shaft e". The first effect of the disks rotation is to liftthe lever 1' and release each stationary stop 0 (see Fig. 51) so that, when the pins q strike the pins p, their wheels may turn until the pins if of the wheels strike against the pawls or in the case of the highest value wheels against the stop i of the At this position the pin n again drops into place when all the wheels will register zero and the part 3" will then have beenreturned to position for operation.

It will readily beseen .in the modification herein before described, in Figs. 1 to 27 inclusive, that the .wheels S, T, U, V, W, form composing means for operating the totalizer wheels, that the toothed segment constitutes the prime factor of the carrying forward means, that the spring detent in the pawl in combination with the tooth n of the totalizer wheels, constitutes a-selective mechanism. A locking means, or means for preventing rotation of the wheels, maybe considered to be the groove and the engaging nose of the pawl,-
