16 Claims. 1
This invention relates to coin counting and sorting machines and has for its object to provide a machine which will add the money value of a batch of coins whether of the same or different denomination and which, after addition thereof, will sort the coins.
I am aware that there are numerous coin sorting devices of record and I am also aware of machines which will count the number of coinsv which are passed through it. However, it is of substantial advantage in the case of collectors for milk and paper routes, of street car conductors, of banking institutions and of numerous other businesses to be able to compute the value of a group or batch of coins. If the collector doubts the computation the batch is kept intact and he may thereafter check the computation.
Another object is to provide a machine having a basket attachment for reception of a large or small number of coins of the same or of miscellaneous value in combination with a rotor which will pick up the coins, one at a time, from the basket and which will transport them past a lever mechanism which sets the counting mechanism into action, the entire machine being capable of motor actuation and hence very rapid operation.
Another object is to provide a computing machine having counting mechanism driven by a motor and merely indexed to counting position by the coins. In other words, the coins themselves do not cause any actuations of the counting mechanism but merely control the positions of center fingers and levers so that the computing effort comes from the motor driven shaft. One advantage of this is that the action is very reliable and positive and differences in weight of coins of the same value do not afiect the operation.
Another object is to provide a machine of high accuracy even though the thickness and diameter of coins of the same value may vary due to differences in usage and care. The diameter of a penny and of a dime, for instance, should differ by approximately fifty thousandths of an inch, but if the dime is new and the penny old and worn that difference may be substantially reduced. I, therefore, employ the coins as actuators of the indexin device and operate the device through levers which substantially multiply the differences thus reducing the chances of error and, in
fact, eliminating errors unless the coins are almost identically of the same diameter.
Other objects and advantages will become more fully apparent as reference is had to the accompanying drawings wherein my invention i illustrated, and in which Fig. 1 is a perspective View of my improved computing and sorting machine,

Fig. 10 is a showing of an indexing member with its various positions shown diagrammatically, I
The coin pick-up More particularly I indicates a basket-like receiver for coins which, in the machine a here illustrated, may be of all the several denominations below one dollar in value. The rear wall of the receiver I is composed of a disc 2 rotatable with the driven shaft 3. Near the periphery of said disc 2 is a ledge 4, and outwardly of the ledge is a plurality of spaced lugs or stops 5. As the disc rotates the coins take their place on the ledge and are carried upwardly out of the basket one at a time by the lugs 5 since the lugs project outwardly but a slight amount from the face of the disc. The pick-up is best illustrated in Figs. 2 and 5.
As the coins are carried across the top of the disc they are forced into a take-off in the form of a stationary plate 6 having a cut-out 1 (Fig. 5) directly in the path of the coins and forming a groove with the disc substantially tangent to the circle of the ledge 4. Outwardly of the plate 6 is a second plate 8 overlying it and spring pressed in the direction of the disc to exert yielding pressure on the coins traveling along the groove. The lugs drive the coins through the groove past the plate 8 at which point they actuate control levers 9, to be hereinafter described, and thereafter they roll freely down the groove and into the sorting device now to be described.
The sorting device The basket I is mounted on the frame-work H! which has legs or base members I I. Attached to these frame members is the sorting device composed essentially of two spaced bars 52 and [3, the lower one of which has a. ledge [4 formed in the top thereof and the upper one of which has a ledge 15 formed in the bottom thereof. The two bars are parallel and inclined rearwardly as viewed in Fig. l with the frontal walls of the ledges coplanar. The ledge I5 is notched along its length, as at it, so that the smallest coin (a dime) will fall between the bars at the first notch l9, but all other coins will continue to roll along the ledge it until the next notch i6 is reached whereupon the next larger coin (penny) will fall between the bars, and so on. Below the bars are baskets ll to catch the coins of each denomination. These baskets may be individually removable or it may be in the form of a single basket with compartments therein removable as a whole.
Referring first to Fig. 5, anchored to the members 18 of the frame [8 is a motor l9, although it will be understood that the machine may be operated manually if desired. The motor l9 has a pulley 28 having a belt 2i therearound which drives the pulley 22 of a shaft 23 which is geared at to a shaft 25. On the end of the shaft '25 i a pinion gear 7.3 in mesh with a large gear 21 fixed to the back of the disc 2 and rotatable about the axis of the shaft 3. It will thus be seen that when the motor i9 is energized by throwing the switch 28 (Fig. l), the shaft 23, the gears 24, shaft 25, gears 26 and El and the disc 2 will rotate and will continue to rotate so long as the motor runs. And it will be seen that so long as the disc 2 rotates it will pick-up coins and feed them over the ledge or run-way 4 and past the levers 9.
The registering mechanism Referring now to Fig. 9, the shaft 23 also has a gear 29 thereon in engagement with a gear 39 of the cam shaft 3 l. Carried by the shaft are two large or primary cams 32 and 33. Immediately above and parallel to the face of each cam 32 and 33 is a gear train composed of a large gear 34 and 35 respectively, in mesh with small coaxial gears 33 and 3? respectively. The gears 38 and 3 as seen also in Fig. 2, are fixedly secured to wheels 38 and 39 respectively, the gears and wheels all being mounted upon and rotatable with respect to the fixed shaft 48.
Secured to the sidewall of the wheel 33 is a gear segment 4| of the type illustrated in Figs. 2 and 7, composed of one female tooth for engagement once each rotation with a tooth of a gear 42 to impart rotation thereto through a small are each time it passes thereover. Fixed to the adjacent wheel 39 is a large gear I43 (Fig. 2) in constant mesh with the gear 42, the gear segment 4i and the gear I43 residing between the wheels 38 and 38.
The operation is as follows: rotation of the gear 34 by the cam 32, as will be hereinafter described in connection with the indexing means, rotates the gear 38 and the wheel 38. This wheel 38 indicates units from zero to nine inclusive and indicia is placed on its periphery accordingly. When the wheel 38 reaches the numeral nine the gear segment-M is so placed that further rotation causes it to engage the gear 42 thus rotatin it and the wheel 39 through a distance equal to one digit on the wheel 35. The wheel 39 is the tens wheel and is provided with peripheral indicia the same as wheel 38. It will be thus seen that if, for instance, the wheel 38 registers 5 and it is then rotated through five more digits that it will register 0 and the wheel 33 will register 1.
In order to permit larger amounts than tens to be registered other wheels 33, 4-: and 45 are added on the same shaft 49. These wheels are each equipped wi h a gear 36 exactly similar to the gear 543, above described. Between the wheel 43 and the gear 45 of the wheel 44, and also between the wheel 44 the gear 43 of the wheel 45 is a gear segment 3!, and coaxially with the gear 42, on the same shaft therewith, are similar gears 41. The operation is the same as above described so that when the wheel 33 rotates from the position where it exposes the numeral nine to the position to expose the zero the wheel 43 is rotated by its segment 44, and so on. The machine, as illustrated, is thus capable of recording $999.99, which is read through the window 48 of the sheeting 49 which covers the operating mechanism,
, The description of the operation, as above described, assumed that the coins were of one cent or of five cent denomination, in which case all actuation would originate at the wheel 38 and, hence, with the gear 34 and cam 32. However, the machine will register ten, twenty-five and fifty cent pieces, and, in this case, the wheel 39 may rotate alone or both wheel 38 and 39 may have to rotate. This is the purpose of the cam and the gear train 35 and 31.
The cam 32 is given a lead with respect to the cam 33 so that in case of a twenty-five cent piece, for instance, the five digit will be added to the exposed number of the wheel 38 with a possible rotation of one digit by the wheel 39 before the two digit is added to the wheel 39. The wheel 39 may thus be rotated by the wheel 38 acting through a gear segment 4|, the gear 42 and the gear M3, or it may be actuated by the gear train 35, 31.
The selection of movements of the wheels and the extent of the movement is controlled by an indexing mechanism which will now be described.
Indexing Referring again to Fig. 9, the shaft 3| has a series of indexing cams 52, 53 and 54 thereon, the elongated cam 53 being, in fact, several cams of the same size and shape placed side by side. An indexing finger 55 has a neutral position immediately adjacent the cam 33 where the shaft is round as indicated in Fig. 10 at Ma just to the left of cam 52. The finger 55 is rigidly secured to, and projects laterally from, a rock bar 58 which is pivotally mounted on a shaft, or rod 51, the shaft passing through a suitable aperture in the finger 55, as indicated at 56 and an apertured ear 59a which projects laterally from the other end of the rock bar. A link 59 (see Fig. 2) connects the rock bar to the parallel swinging control levers 9 so that when these levers are caused to be swung by a coin passing from the disk 2 to the coin chute formed by the bars 12 and I3, the rock bar will be moved to the left, as shown in Fig. 2 and to the right, as shown in Figs. 9 and 10, an amount dependent upon the size of the coin. Obviously a, dime will cause the rock bar to be moved, or slid, along the shaft 51 a certain predetermined distance, while each of the larger sized coins, viz: a penny, nickel, quarter or half-dollar, will cause the rock bar 58 to be slid a greater distance to the right in Figs. 9 and 10, dependent upon the diameter of the coin. When the registering mechanism is in neutral position, the finger 55 is located in alignment with the cylindrical portion 3 hr of the shaft 3|. When the rock bar has been moved to the right in Figs. 9 and 10 by a dime, the finger 55 will align with the cam 52; for a penny, five cent piece or quarter the finger will be aligned with the elongated cam 53, while for a half-dollar the finger will be aligned with the cam 54.
The rock bar 58 has a ledge 68 which varies in width along its length to provide a plurality of shoulders 6|, 62, 63, 64, 65, 66 and 61. Upon elevation of finger 55 and rocking of the bar 58 one or the other of these shoulders will contact one or the other or both of the lower ends 68 or 69 of bell cranks pivotally mounted on the shaft 51 with their outer ends 18 and II, respectively, having notches 12 and 13 in the lower edge thereof. The amount of rocking will obviously depend on the height; of the shoulder which contacts the ends 68 and 69.
The gears 34 and 35 are rotatably mounted on a common shaft 14. Alongside each of these gears and freely mounted on the shaft 14 are the arms 15 and 16, each having a greater length than the radius of the gears 34 and 35 and having pawls I1 and 18, respectively, pivotally mounted thereon and having cam contacting arms 19 and 88, respectively, in the plane of the cams 32 and 33, respectively,
The arm 15 has an extension 8| and the arm 16 has an extension 82. Attached to each of these extensions are the springs 83 and 84, respectively. The spring 83 is attached at its other end to a bell crank 85 (as best seen in Figs. 3 and 4) pivotally mounted on a stationary shaft 86 and having a pawl 81 at its outer end in engagement with the gear 34 to prevent coasting of the gear. The spring 84 is similarly attached at its outer end to a bell-crank 88 pivotally mounted on the shaft 86 and having a pawl 89 in engagement with the gear 35. The springs 83 and 84 thus urge the arms 15 and 16 away from the reader as viewed in Figs. 4 and 9, and hence try to swing the cam contacting arms I9 and 80 into engagement with their cams 32, 33 respectively for maximum elevation thereby. However, the arm 15 has a flange 98 and the arm 16 has a fiange 9| adapted to engage the notches l2 and 13 respectively of the arms 10 and H, the arms 10 and 1| being spring pressed downwardly by the springs 92 and 93 (see Fig. 4).
Mounted upon one side of the unit wheel 38 is a sprocket wheel 50, between the projecting teeth of which is adapted to be engaged a small laterally projecting fiange formed at the outer end of an arm which is formed integrally with the arm 15. When the arm 15 is in neutral position, the laterally projecting flange of the arm 5| will engage between the teeth of the sprocket wheel 58 and hold the sprocket wheel 50 and gear 38 from movement and will also prevent coasting of the gear 38 and wheel 50 after the latter has been actuated in a manner presently to be described. The provision of the gear 42 between the unit wheel 38 and the gear I43 secured to the side face of the tens wheel 39 and the provision of the similar gears 41 and 46 between the wheels 39, 43, 44 and 45 serves to prevent coasting of these wheels. The sprocket wheel 50 is integrally united with the small gear 36 which is driven by the large gear 34 and when the gear 36 is rotated by means of the large gear 34, rotation thereof is imparted to the wheel 38 by means of a spring pressed pivoted pawl 50a (see Fig. 8) mounted upon a, pin 50!) secured in the sprocket wheel 50 and projecting laterally from the inner face thereof into the interior of the wheel 38. The pawl 58a is normally held by an expansion spring 5| with the tooth end of the pawl in engagement with the inner cylindrical face of the wheel 38, this face of the wheel being provided with suitable slots, or grooves, for engagement by the toothed end of the pawl 5811, so that the wheel 38 will be held with its indicia in proper position for registry with the observation window 48. Each of the wheels 39, 43, 44 and 45 are similarly constructed.
The operation of the indexing mechanism is as follows: Suppose that a twenty-five cent piece is being impelled past the levers 9 thus rocking these levers by an amount proportionate to the diameter of the coin. This causes the link 59 to be pulled to the left, as viewed in Fig. 2, thus traversing the rock-bar 58 and the finger 55 to th right as viewed in Fig. 9. Each coin will traverse the rock bar and. finger a different amount because each is of different size. A dime will traverse the finger 55 in the path of the cam 52 while a penny, a nickel and a quarter will traverse it to some point in the path of the composite cam 53, and a half a dollar will traverse it in the path of the cam 54. It will be remembered that the shaft 3| with the cams 52, 53 and 54 is motor driven so that as the cam 53 rotates it elevates the finger 55 causing the bar 58 to rock and forcing one of the shoulders, 6|, 82, 63, 64, 65, 66, 61 against the arm 68 or 69 or both.
Fig. 10 illustrates which shoulder is called upon to do the actuating. The full line position A shows the finger 55 in neutral position, riding on the cylindrical portion 3| a so that it is not subject to elevation. Traversal of the finger and rock-bar to the position B is brought about by insertion of a dime and causes actuation of the arm 69 by the shoulder 61. The position C is brought about by insertion of a penny and causes actuation of the arm 68 by the shoulder 62, the position D by insertion of a nickel and causes actuation of the arm 68 by the shoulder 6|, the
. position E by insertion of a quarter and causes actuation of both arms 68 and 69 by the shoulders 6| and 65 respectively, and the position F by insertion of half a dollar which causes actuation of the arm 69 by the shoulder 64. These shoulders vary in height in order to impart different movements to th arm 68 and 69. Thus, in the case of a dime the shoulder 61 actuates the arm 69 by an amount just sufiicient to trip the arm II so thatthe flange 9| may fall into the second notch 13. The normal position of the flange 9| is in the first or outermost notch 13, and when in the normal position the arm is not sumciently in the path of the cam 33 to be actuated thereby. However, when the flange 9| drops back one notch the cam will then strike the arm 80, rocking it about its pivotal mounting on th arm 16, thus first elevating the pawl 1'8 into engagement with a tooth of the gear 35 and thereafter impelling the gear 35 through a short arc sufficient to cause rotation of 7 gear 31 and the register wheel 39 through one digit.
A penny will function similarly but the action will be through the shoulder 62, the arm 60, the arm 10, the notches 12, the arm 19, cam 32, pawl 11, gear 34 and register wheel 38.
A nickel will function exactly the same as a penny except that the wider shoulder 6| actuates the arm 68 a greater amount thus raising the arm 10 to an extent such that the flange 90 on arm 15 completely clears the notches 12 so that the full lift of the cam 32 can be imparted through the arm 19 to the pawl 11, the full lift impelling th gear 34 through an arc suflicient to cause the unit wheel 38 to rotate through five digits.
A quarter will cause the shoulder 6| to impart through the arm 68 the full lift of the cam 32 to the arm 19 and pawl 11 as described in the case of a nickel, and it will also cause actuation of arm 69 by the shoulder 65. The shoulder 65 is of a width such that the flange 9| will fall back two notches i3. The position of the parts as shown in Fig. 9 of the drawings are for this setting, the flange 90 being in completely released position with respect to notches T2, and the flange 3| being in engagement with the third notch 73. As the shaft 3| and cams 32 and 33 rotate the cam 32 will impart its full lift to the arm 19 thus swinging the pawl 11 into engagement with the teeth of the gear 34 and rotating the unit wheel 38 through five digits. Thes five digits may be added to a previous registering so that the addition of these five may cause rotation through one digit of the tens wheel 39 because of the action of the segment 4| and gear 42 as previously described. For this reason the movement of the unit wheel 38 is completed before the cam 33 begins to impart its lift to the arm 80 and pawl 38 by which the gear 35 and tens wheel 39 is then rotated through two digits.
A half dollar will cause the finger 55 to travel to a position in the path of the cam 54 and will traverse the rock-bar 58 to the position F of Fig. 10 where the shoulder 64 will raise the bell crank arm so that the flange 9| will not engage any of the notches 13 thus permitting the cam 33 to impart its full lift to th arm 80, the full lift .impelling the gear 35 and rotating the tens wheel 39 through fiv digits.
After each upward actuation of either of the gears 34, 35 is completed by the throw of their respective cams 32 and 33, and the cam rider arms l9 and 80, the throw of each of the cams 52, 53 and 54 will have passed the finger 55 permitting the rock bar 53 to move away from the arms 33 and 59 hus allowing the arms 10 and H to rest upon the lateral flanges 90 and 9| of the arms '35 and H respectively. The throw of the cams 32 and 33, however, pushes the arms .5 and 15 forwardly (Fig. 9) an amount suflicient to bring the flanges 90 and 9| into alignment with the outermost or first of the notches 72 and E3 of the arms and M respectively which are pulled down by the springs 93 to cause the arms 75 and 76 to be locked in their neutral position, the pawls Tl, E8 dropping out of engagement with the teeth of gears 34, 35. By the time this action has occurred th finger 55 is riding on the cylindrical or concentric portion of the cams 52, 53, 54, thus permitting the torsion spring |53 (Fig. 3) one end of which is anchored and the other end of which engages one of the control arms 9, to return the latter to their neutral or initial position and to slide the rock 8 bar 58 and finger to the neutral position indicated at A in Fig. 10.
It will of course be understood that the disc 2 operates in timed relationship with the drive shaft 3| and the pins 5 are so spaced on the disc that the shaft 3| will complete a full revolution during th time that elapses after one pin 5 passes any given point until the following pin reaches that point, or more specifically the point where a coin of any denomination engages the control device carried by the arms 9 until a coin ahead of the following pin engages the control device. Obviously the timing is such that the sliding movement of the rock bar 58 and flnger 55 leads or is ahead of the swinging or rocking movement thereof in order that the finger 55 may be brought into alignment with the proper one of the cams 52, 53, 54 for the respective coin and the corresponding shoulders on the rock bar aligned with the arms 68 and 59. It will be noted that the throw of each of the cams 52, 53 and 54 is the same; the variation in the amount of movement of the arms 68 and 69 being effected by the difference in the heights of the shoulders 6|, 62, 64 and on the rock bar. It will also be seen that although the throw of the cams 32 and 33 is suflicient in th constructional example illustrated to rotate each of the gears 34 and 35 a distance suflicient to register five digits on the unit and tens register wheels 38 and 39 respectively on each rotation of the drive shaft 3|, the wheel 38 will only be moved one digit for a penny because the rock bar will only lift the bell'crank arm 10 enough to let the flange of the arm T5 engage in the second notch 12 thus permitting the pawl 11 to drop back but one notch or tooth of the gear 34 thereby preventing the cam rider arm 13 from engaging the cam 32 thus causing only the outermost portion of the throw of the cam to be effective.
The resetting mechanism The machine is quipped with a resetting mechanism such that an operator may return all wheels 38, 39, 43, 44 and 45 to show a zero setting through the window 48 at any tim merely by actuating a trip handle 95. This part of the machine is best seen in Figs. 6 and 9.
Mounted on and rotatable with respect to the shaft 14 is a gear 96 of substantially the same size as the gears 34 and 35. A re-set cam 91 is provided on the motor driven shaft 3| below the gear. Journalled on the shaft 14 alongside the gear 96 is an arm 98 of greater length than the radius of the gear 96 and having a detent pivotally mounted on the lower end thereof composed of a pawl 99 and a. cam contacting arm I00, the detent thus being capabl of acting as a tappet between the cam 91 and the gear 96 in a manner analagous to those previously described in connection with gears 34 and 35. The arm 98 has an extension |0| on the opposite side of the shaft 14 from the detent, and a spring I02 is connected thereto.
The other end of the spring is connected to the outer end of an arm |03 of a bell crank pivotally mounted on the stationary shaft 86 and having a pawl I04 on its other end for engagement with the teeth of the gear 96 to prevent coasting. The arm 98 is thus spring biased in the direction to cause engagement of the arm I00 with the cam 91. In order to lock the arm 98 intoa position to remove the arm |00- from the path of-the cam 91, I provide a lug I05 for engagement with an arm I06 journalled on a fixed 9 pivot I01 and biased by a spring I08 in the direction of contact with the lug I05.
The arm I06 extends upwardly beyond its pivot I 01 into a further arm I09. Along the length of this arm I09 the trip handle 95 is securely mounted. The outer end of the arm is bent to form a pawl IIO for engagement with a depression III in a disc H2 fixedly mounted on the shaft 40 upon which the registering wheels are mounted. Coaxial with and fixed to the disc H2 is a gear H3 in constant mesh with the large gear 96.
The operation is as follows: with the parts in the position illustrated, and best seen in Fig. 6, the re-set mechanism is not functioning. If the lever 95 is pushed to the left the arm I06 will be swung from the path of the lug 105 thus permitting the arm 98 to swing th arm I into contact with the cam 91. At the same time the pawl H0 is lifted from its locking position with respect, to the depression III so that the gear H3 and disc H2 are free to rotate. As the cam 91 rotates it will actuate the arm I00 thus lifting the pawl 99 into engagement with the gear 96 so that continued rotation of the cam 91 will cause the gear 96 to rotate through an arc. This will cause the gear H3 and the shaft 40 to rotate through an are equal to one digit On any or all register wheels. At every revolution of the cam 91 a similar actuation is again imparted to the gear I I3, disc I I2 and shaft 40 until the pawl H0 again drops into its recess II I.
The shaft 40 is stationary for all registering operations, rotation of the wheel 38 being effected by the rotation of the gear 36 and sprocket Wheel and the pawl connection 50a shown in Fig. 8 between the sprocket wheel 50 and wheel 38. A similar connection, as hereinbefore set forth, is provided between the gears 43 and wheel 39 and between each of the gears 46 and the remaining register wheels 43, 44 and 45. The shaft 40 has formed thereon a number of shoulders 40a, one for each register wheel and located within the inner part of each wheel. Each of the register wheels is preferably formed as a cup-shaped member having an annular cylindrical portion on which the indicia are suitably rinted or marked on the outside surface thereof and a flat bottom side wall portion. tion of each wheel has a pin I40 (see Fig. 8) projecting laterally therefrom upon which is pivotally mounted a pawl I4I the end of which is adapted to engage with the shoulder 40a,
the pawl being held in engagement with the shaft 40 by means of the leaf spring I42, all as shown in Fig. 8. As the wheels 38 are driven in a counter-clockwise direction (Fig. 8) during registering operation while the shaft 40 remains stationary, the pawl MI is inoperative. When, however, the shaft 40 is driven to perform a resetting operation in a clockwise direction, as indicated by the arrow in Fig. 8, the pawl I4I will be held by the spring I42 in the path of movement of the shoulder 40a and will cause the register wheel to be moved. It will be understood that the location of the shoulder 40a and pawl I4I are so arranged with respect to each other and the indicia of the registering wheel that the distance from the free end of the pawl to the shoulder 40a will be in accordance with the numeral of the registering wheel exposed through the window 48 at the time the resetting mechanism is set in operation and that the shoulder 40a and pawl I4I for each of the regis- This side wall porr 10 tering wheels will come into operation for each wheel in accordance with the amount of travel required by each wheel to return to its position of zero reading.
