9 Claims.

My invention relates to machines for counting coins, tokens and other pieces and articles of the same general nature, and herein (and in the claims as well as in the following description) the term coin is used as including tokens and analogous pieces as well as monetary coins. More especially it relates to machines for counting out coins in lots of a definite number each (e. g., dimes in lots of fifty, etc.'), and it is peculiarly adapted to semi-automatic machines where the counting of each lot is begun by some act of the machine operator.

Broadly it prevents in an improved manner miscounting of individual lots. More particularly it comprehends an improved arrangement for positively indicating in a distinctive and peculiar manner the completion of the count or passing of the number of coins. desired for each lot. The manner in which the indication is given is immaterial, broadly speaking, so long as it is positive in operation, i. e. normally beyond the control of the operator, and is distinctive and peculiar to itself, i. e. is an indication of an order different from such an indication as is given, for example, by the totalizing register usually used on counting machines and which at all times shows visually the total number of coins passed through the machine from the beginning of a series of counting operations; thus it is immaterial whether the indication be given by erecting a distinctive signal at the end of each counting cycle, by the thrusting out of coin-receiving containers at the ends of the counting cycles, by stopping or discontinuing the coin flow as each counting cycle is completed, or in some other manner. As will be appreciated, the indications of the ends of the cycles or counts given by a totalizing register are not distinctive or peculiar since they consist merely of certain of the 40 numbers of the whole series that the register is capable of showing; for the present purposes such a signal or indication is too inconspicuous and too nearly like the signals or indications that precede and succeed it, especially for rapid 45 work. By positively'indicating the end of each counting cycle or operation in a distinctive and peculiar manner however, the operator is given timely and unmistakable notice whenever the machine is operating, or is being operated, im-

properly. When the indication is given by discontinuing the flow of coins through or from the machine, it is immaterial, generally, whether the flow be stopped by placing a gate in the coin path or otherwise; especially when the coins are fed through the counting mechanism by friction,

the flow may bestopped by rendering the counting mechanism inoperative to pass coins. Preferably however I lock the machine against premature closing or completion of the successive counting cyclesor operations.- According to the- 5 present invention I put the release of the lock under the control of some member driven with the flow of coins through the machine and making some certain movement at and only at the end of each cycle or operation. This con- 10 trol member may be (and conveniently is) a member associated with the counting mechanism either as a necessary part thereof or as an addition thereto for locking purposes. The locking of the machine can be done in various ways; for 15 example, by preventing the removal of coin-receiving containers until the respective container has received the number of coins intended for it, or by preventing .the re-settlng of the machine for starting counting any second lot of coins until the counting of the preceding lot has been completed, etc. etc. Thus the release of the lock serves to indicate the completion of the successive counts, and the locking feature may quite assure proper counting in all respects. In semiautomatic machines where the re-settlng of the machine for starting counting successive lots is at the will of the operator, improper re-setting (resulting in miscounting) is more likely to occur near the end of a cycle rather than earlier; accordingly the lock should be efiective near the end of each cycle but (at least in these semi-automatic machines) the lock may be omitted from the beginning or even from the middle portion of each cycle. The contrast between the lock of my invention and the mechanisms heretofore used for the purpose of stopping the flow of coins at the end of each cycle will be apparent. So far as I am aware all such prior stopping mechanisms (at least in the semi-automatic machines) have been so constructed that the operator can remove the stop from action before a count has been completed and re-set the machine for beginning a new cycle or count before the end of the preceding count is reached, with the result (for example) that through inadvertence or carelessness the operator may cause a certain lot of coins to contain less than the desired number and add the missing coins to the next lot. In contrast with this the lock of my invention prohibits the completing of the counting of any lot until the full number of coins desired for that lot have been counted.

The accompanying drawings illustrate the form of my invention preferred at present. In these drawings, Fig. 1 is a plan view of a portion of a machine embodying my invention. Fig. 2 is an elevation thereof, partly in section. Fig. 3 is a vertical section substantially on the line III'I1I of Fig. 1. .Fig. 4 is also a sectional elevation, at a position slightly removed from that of Fig. 3, and showing the parts in a different position. Fig. 5 is a sectional plan view showing the star wheel and counters. Figs. 6 and 7 are sectional views showing a stop pin in two different positions and its relation to a counter." Fig. 8 is a sectonal view near one of the lock pins. Fig. 9 is a corresponding sectional view, but showing a modification.

In the machine illustrated the coins are delivered to the rotatable disc l, which is more or less surrounded by a vertical wall 2; the disc is rotated rapidly so that by centrifugal force the coins pass from it through the passage 3 underneath the wall 2 at one side and thence underneath the driven wheel 4 which assists to pass them through or over the counting mechanism. Machines of this type are well known and the foregoing description will serve present purposes; only part of the disc I and wall 2 are illustrated, as will be understood.

In passing underneath the driven wheel 4 (which usually is surfaced with rubber or the like to give the wheel a good frictional grip on I each coin) each coin'is passed across a notched or star wheel 5, so that this wheel is turned one step or notch with the passage of each coin. A shaft 6 to which the star wheel is attached and cooperating bevel gears and 8 cause this star wheel to actuate the totalizing register or counter 9; a thumb nut ||l permits this totalizing counter to be re-set to zero at will, and accordingly the numerals appearing at the windows ll of the counter show at all times the number of coins passed through the machine since the counter was last set back to zero. A ratchet wheel l2, fixed either directly to the star wheel 5 or to its shaft 6 and having say the same number of teeth as the star wheel 5, together with a spring pressed pawl |3, actto hold the star wheel 5 at rest except during the passage of a coin, and to stop the turning of the star wheel 5 at the proper place for the reception of a succeeding coin. Substantially this construction is already known and the foregoing description will suflice for the present purposes. In the present machine, generally speaking, the counter 9 is used to show the total number of coins passed through the machine in a series of counting operations.

The present machine is so constructed that it counts out the coins in lots of definite numbers of coins per lot, lots of either large or small numbers being counted as the will of the operator may dictate, say lots of twenty, twenty-five, forty or fifty coins each; also it is semi-automatic in its action in that the machine requires the action of the operator to restart it for counting each succeeding lot of coins. Counting elements or counters in the form of discs 20 and 2| serve to stop the star wheel 5 against further rotation temporarily at the completion of each counting cycle; that is as each lot is completed they stop the coin flow until the machine is reset by the operator for further counting; counters of other form than discs may be used, as will be understood, but the disc form is preferred. Also, rather than use one counting element or counter for each lot of coins, I prefer to so arrange the apparatus that each counter serves for counting two or more lots of different numbers of coins. Thus for the counting of four different lots (e. g. lots of twenty, twenty-five, forty or fifty coins per lot) I employ preferably two counters 2|] and 2|. These may be driven by the star wheel 5 in various ways. In the present instance the counter 23 is provided with gear teeth on its periphery, these teeth gearing with the smaller gear 22 fixed to the star wheel shaft 6, and the counter 2! has gear teeth meshing with the gear teeth of the counter 20, the number of gear teeth respectively being such that the counter 2|! makes one complete rotation in the passage of fifty coins over the star wheel 5 and the counter 2| making one complete rotation in the passage of forty coins. A stop, or stop latch so-called, 23 carried by the upper face of the counter 20, and two stop pins 24 and 25 carried by the frame of the machine and either or both of which can be thrust down into the path of the stop or stop latch 23, serve to stop the rotation of the counter 28 and thus stop the fiow of coins. If say only the stop pin 24 is thrust downinto the path of the stop 23, then (the stop pin being lifted out of the pathmomentarily to permit the mechanism to start) the counter 20 can make one complete rotation before being stopped by the stop pin, and thereby a lot of fifty coins counted out. The stop pin 25 being located diametrically opposite the stop pin 24, the insertion of both these pins in the path of the stop or stop latch 23, causes the counter 20 to stop at the end of each half rotation, and accordingly the flow of coins is interrupted at the ends of the counting of lots of twenty-five. 'In order to permit the bare momentary lifting of these stop pins to start the counting of a succeeding lot of coins, the stop 23 is pivoted about the centering shaft 26 of the counter, its movement on the face of the counter is limited by two stops 2'! and 28 carried by the face of the countenand a spring 29 is employed to thrust the stop latch 23 against the stop 21. Thus the rotation of the counter having been stopped by the latch 23 striking the stop pin 24 and the pressure of the counter stop 23 against the latch 23, the counting of the next lot of coins can be started by momentarily lifting the stop pin 24, because this lifting permits the counter spring 29 to immediately thrust the stop latch 23 underneath the stop pin 24 so that when the latter is dropped down again it cannot get in front of the stop latch 23 again until the counter 20 has made a complete rotation. The stop pin 24 may be pressed downwardly by a spring or by gravity, so as to drop into the path of the stop latch 23 as the turning of the counter 20 carries this stop latch 23 from underneath the end of the stop pin 24. The functioning with respect to the stop pin 25 is the same as described with respect to the stop pin 24. Obviously other constructions of the stop latch 23, serving the same purpose, can be substituted.

In the same manner, the counter 2| is provided with a. similarly mounted stop latch 30 and two stop pins 3| and 32 placed diametrically opposite each other, and accordingly when, say, stop pin 32 alone is placed in the path of the stop latch 30 (the stop pins of counter 20 being raised out of operation) the flow of coins is stopped at the completion of the passage of forty coins while the presence of 'bothstop pins 3| and 32 in the path of the stop latch 30 causes the flow of coins to be interrupted at the ends of the passage of lots of twenty coins per lot.

Preferably all the stop pins, e. g. 24, 25, 3| and 32, are carried by a single structure capable of raising whichever stop pin may be employed at the moment, for coin-counting restarting purposes. In the present instance this stop pin carrier comprises a plate-like member 36 hinged at 31 and held downwardly by gravity and a spring 35. It is raised (turned on its hinge 31) by the operator each time the counting of a new lot of coins is to be started. Usually this raising is put under the control of a pedal under the control of the operators foot. For this purpose, a short lever '38 isprovided, beneath a tongue 39 projecting from the carrier plate 36, the lever being hinged to the machine frame at 4|] and having its movable end linked by 4| to a lever 42 connected to a pedal 43 within convenient reach of theoperators foot; by depressing the pedal 43 it will be observed that the stop pin carrier plate 36 will be raised or turned on its hinge so as to lift any stop pin 24, 25, 3| or 32 that may at the moment be in the path of one of the stop latches 23 or 30. It will be obvious that the stop pins can be mounted in the stop pin carrier in various ways. The preferred form of mounting is illustrated in detail with respect .to the stop pin 24; the other stop pins are similarly mounted. In brief, the stop pin 24 is provided, near its lower end, witha .cross pin 44, and the pin 24 is slidably mounted in a tubular portion 45 of the stop pin carrier, the tubular portion having two narrow cuts 46 and 41 extending upwardly from its lower end and at right angles to each other; a spring 48 holds the stop pin 24 upwardly to the extent permitted by the cross pin 44 lying in one of the slots, and a lock nut 49 threaded on the stop pin and engaging the upper end of the tubular portion 45, serves to prevent the pin being depressed inadvertently. One of the cuts 46 extends upwardly so far that when the cross pin 45 lies in this cut, the pin spring 45 holds the pin elevated well-above the path of the counter stop or stop latch 23. The second cut 41 extends upwardly such a short distance however that when the cross pin 44 lies therein the stop pin 24 reaches down into the path of the stop latch 23 as shown in the drawings. Therefore by releasing the lock nut 49, the stop pin 24 can be thrust down far enough to free its cross pin 44 of both slots, then the pin can be turned one way or the other so as to place the cross pin in either slot, and then the thumb nut 49 screwed-down against the tubular portion 45 to lock the stop pin in its corresponding raised or lowered position. The other stop pins 25, 3| and 32 being similarly mounted, it will be evident that they are individually achustable into and out of the paths of the stop latches 23 and 30. Suitable heads 50 on the respective stop pins are to permit their manipulation. For enabling a single counter, such for example as the counter disc 20, to be used for counting lots of two or more numbers of coins, I have found that the use of a plurality of stop pins, such as 24 and 25 for example, in operation with, say, a single stop or stop latch on the counter, is preferable to other arrangements heretofore proposed.

The present machine has a slideway 56 down which the coins pass as they leave the driven the counted coins, each tube receiving one complete lo t.

Assuming for example that the stop pin 24 is located with its cross pin 44 in the second slot 41 and that all the other stop pins are positioned with their cross pins 44 in the respective higher slots 46 (so that only the stop pin 24 is positioned to stop the counting mechanism and hence the flow of coins) it is obvious that the machine will count the coins in lots of fifty, stopping the coin flow at the completion of the counting of each lot; providing the machine is operated as intended. As is well known however, a careless operator may depress his foot pedal 43 and thus raise the stop pin 24 from the path of the stop latch 23, say just prior to the completion of the counting of fifty coins; say when only forty-eight coins of a given lot have been counted out and passed to a container in the container member 51. Taking his foot from the pedal 43 a moment later, the stop pin 24 may fall on top of the stop latch 23, quite as though the machine had counted a full lot of fifty coins, and the counting continued quite as if everything were operating as intended. The result of this is that'the containerreceiving the next lot of coins may receive its own lot of fifty and two additional coins that should have been delivered into the previous container that received only forty-eight coins. .The foregoing is an example of misoounting that my invention prevents. Briefly the machine illustrated prevents such miscounting through the agency of mechanism which prevents raising of the stop pin carrier 36, and thus removal of the operating stop pin fromthe path of the respective stop latch 23 or 30, until the counting of each and every lot is completed. To this end the stop pin carrier 36 is provided with two lock pins 60 and BI for cooperation with the coin counters 20 and 2| respectively in such a manner that the stop pin carrier 36 cannot be raised to reset the machine for starting the counting of a succeeding lot of coins until the respective counter has come to the position it must occupy when the counting of a preceding lot of coins is completed. In the present instance, the cooperation between the lock pin 6| and the counter 2| is like that between the lock pin 60 and the counter 20, and in the present instance the counter 20 is provideo. with an overhanging rim 62 (which may be attached to or integral with the counter 20), and the stop pin 60 is provided with a swinging latch 63 spring pressed inwardly as indicated, so that when the stop pin carrier 36 is lowered (to place one of the stop pins in operating or counting position) the lock pin latch 63 passes this rim 62 and takes its place beneath the rim. At the point of the rim 62 which is adjacent the stop pin 60 at the completion of the count of a lot of say fifty coins, the rim is provided with a gate 64 through which the lock pin latch 63 can pass; also, since the same counter 20 is used to count another number of coins, say lots of twenty-five, the rim 62 is provided with a corresponding additional gate 65 through which the stop pin latch 63 can pass upwardly. As a. result, it will be evident that the stop pin carrier 36 can be raised to remove an active or operating stop pin 24 or 25 from in front of the stop latch 23, to reset the machine for counting a lot of coins, only after the counting of the preceding lot has been completed; i. e. when one of the gates 64 or 65 comes to a place above the lock pin latch 63. As before stated, the same interlocking relation is employed between the counter 2! and the lock pin'6l. Inasmuch as two lock pins and Bl are employed, each is mounted for movement into and out of operating position so that either can be brought into operating position as the need for either of the counters requires, and the other can be removed from operating position so as not to interfere with the desired locking operation. To this end both look pins are so mounted that either may be turned say ninety degrees so as to place its latch 63 quite outside the path of the cooperating counter rim 62 (See Fig. 5). To this end, in the present instance, the lower portion of each lock pin (portion pointed to by the reference characters 60 and (ii) is made polygonal in cross section and the tubular support 61 for the lock pin on the stop pin carrier 36 is similarly recessed at its lower end; the lock pin may be spring pressed downwardly as indicated; normally each lock pin is held elevated with the polygonal portion extending into the recess, by means of a lock nut 68. By turning this look nut 63 however, the polygonal part can be dropped out of the recess, then the lock pin can be turned the necessary amount to carry its latch beneath or out from under the counter rim 62, and then pulled back upwards into the recess again by means of the lock nut 68.

Thepresence of the appropriate gate, e. g. 64 or 65, at the respective lock pin latch 63, i. e. the ability of the operator to raise the stop pin carrier 36, is a positive indication or signal to the operator that a desired lot of coins has been counted out, and counted out complete. Also it will he observed that the joint use of stop pins and the lock practically requires at least momentary stopping or discontinuance of the coin flow at the completion of each lot, and this too acts as a signal to the operator of the exact completion of each desired count.

It will be observed of course that the locking may be accomplished by other mechanisms. As a single example of an alternative construction, Fig. 9 illustrates one using the stop pins themselves to lock the stop pin carrier 36 against inadvertent raising. In this instance the counter 128 (corresponding say to the counter 20 of the preceding figures) is provided with an inturned rim I62, and the stop pin I24 (corresponding say to the stop pin 24 of the preceding figures) is provided with a latch I63 (similar say to the latch 63 on the lock pin 60). The inturned rim 1 E2 being provided with a gate corresponding say to gate 6 5 before described, but located at that point of the rim I62 which stands opposite the stop pin 24 at the end of each complete counting cycle, it is evident that the arrangement briefly illustrated in this Fig. 9 will operate in substantially the same manner as described with respect to the foregoing figures.

I prefer to provide centrifugal discs like I with a number of holes 69 pierced completely through it to permit the escape of dirt. Prefer ably these holes are all placed within the periphery of the disc so that its outer edge 10 is continuous and uninterrupted. These holes 69 may be provided in sufficient numbers, and usually are more or less distributed throughout the disc, and each is too small, diametrically, to receive the smallest coin that the machine is intended to count. To permit the complete escape of the dirt falling through these holes 69, the support H on which the centrifugal disc rests, may in effect he provided with holes to let-thedirt fall'through, e. g. such as-indicated at-l2., q

As is customary inmachines of the type illustrated, a sliding guide plate 13 may be provided, this being slidable to the right and to the left in Fig. 1 to widen and narrow the coin pass 3 immediately at the star wheel 5. This may be positioned by a hand lever 14. In such and other respectsthe machine may contain various features found on-machines of the type of that illustrated.

It will be understood that my invention is not limited to the construction and operation described above and illustrated in the drawings, except asappears hereinafter in the claims.
