Figure 17 is a detail perspective of the regulator means.

An embodiment of coin handling mechanism comprising a counting machine, as shown in Figure 1 consists of a support, such as a base 20, provideo with a plurality of upright standards 21 arranged to support on their upper ends a coin retaining ring comprising a circular horizontal foot plate 22 attached to the standards, and a vertical wall portion 23 rising therefrom in concentric relation thereto.

A spindle 24 jour'nalled in the base 20 and foot plate 22 extends axially up through the retain ing ring, carrying a conveyor disc 25 disposed with its periphery in a slight clearance with respect to the ring wall 23 at about the central section of the wall. A coin feed hopper 26 is mounted over the top of the retaining ring 23 by means of a plurality of radially arranged hanger brackets 27 fastened at their lower ends to the foot plate 22 externally of the ring wall and with their upper ends being directed inwardly over the top of the ring wall and attached to the circular horizontal base plate 28 of the hopper, whereby the hopper is rigidly mounted with respect to the coin retaining ring with its base plate 28 substantialy flush with the upper edge of the ring.

The hopper 26 is of the funnel type having a restricted neck 29 and the under face of the base plate 28 is formed with an annular recess 30 opening to the hopper neck and providing a guideway of suflicient depth and diametrical extent to permit the ready sliding thereinto of coins, indicated as at 31, which lie flat on the top face of a cover disc 32 disposed over a star wheel annulus 33 seated on the carrier disc 25. The diameter of cover disc 32 is slightly greater than that of the guide- 1 way 30 so that the periphery of the cover disc lies beneath the overhang of the hopper base plate I face and the base plate of the hopper.

28. The maximum diameter of the star wheel is substantially equal to the diameter of the cover disc 32 which it underlies but is no greater, and securing elements 34 are employed to effect a rigid connection between the cover disc, star wheel, and carrier disc which is in. turn fixed to the spindle 24 so that upon rotation of the spindle, the carrier disc, star wheel, and cover disc rotate as a unit.

The spindle 24 is driven through gearing indicated generally as at 35 actuated from a power shaft 36 having an operating crank handle 37. Motor drive, not shown, may be substituted for manual operation where desirable.

lhe hopper base plate 28, as best shown in Figure 3, has a tangential coin discharge channel 38 cut therethrough and opening to the coin guideway 30. The width of this channel may be varied to the requirements of different sizes of coins by means of an adjustable abutment block or finger 39 attached to the under face of the base plate at one side edge of the channel and movable to swing across the channel as desired. By this means only one coin at a time is permitted to enter the discharge channel. The block 39 is pivoted in threaded engagement with a bolt stem 49 which may be tightened in the usual manner to clamp the block against the plate and bind the l ck in position as set.

A coin rake ofi" arm 41 extends tangentially inward from the retaining ring 23 to which it is rigidly attached through a lip 42, across the carrier disc and a portion of the cover disc 32, substantially filling the space between the disc sur- Between the periphery of the cover disc and retaining ring the body of the arm has a vertically enlarged portion 43 provided with a straight bottom edge spaced sufiiciently above the surface of the carrier disc to permit passage of coins beneath the arm.

Substantially opposite the rake ofi arm 41 the retaining ring 23 has a segment thereof removed and in the opening thus provided there is arranged coin counting mechanism comprising a star wheel member 44 and an'attached cover disc 45 fixed as a unit to a spindle 46 to rotate therewith and including a toothed wheel 47 fixed to the spindle. A pinion 48 on the spindle is meshed l with the actuator pinion 49 of a register 50 of any suitable type which is mounted on a saddle bracket 51 attached to the floor plate 52 of a frame 53 on which the entire assembly of the countin mechanism is disposed.

The counting mechanism support frame is pivoted upon one of the standards 21 to be swung in a horizontal whereby to move the star wheel 44 and associated cover disc 45. toward or away from the main star wheel 33 and its cover disc 32 over the subjacent exposed portion of the carrier disc 25. A link 54 pivoted to another of the standards 21 carries a threaded bolt 55 slidably engaging a slot provided therefor in the frame plate 53. A wing nut 55 threaded on the bolt stem provides a means for clamping the link and frame together to hold the counter supporting frame in a set adjusted position for the re-.

ception of a particular size of coin between the star wheels.

Positive actuation of the counter mechanism is assured by the provision of means for preventing actuation thereof except by coins. Such a means includes a ratchet arm 5'7 pivoted to the saddle bracket 51 and urged at all times into bearing engagement against the toothed wheel 47 by a spring 58 connected between the arm and bracket. The engaging end of the arm is provided with a head to interengage the teeth of the wheel 47 whereby the rotatable elements of the counter mechanism are held against accidental or too rapid movement. A dog 59 influ onced by the spring so engages the points of the star wheel 44 to hold the wheel in proper position for engagement by coins.

Means are provided in advance of the counting mechanism for directing coins on the carrier disc into positive engagement with the coin seating recesses of the main star wheel 33. One such means comprises an arcuate finger 61 pivoted at one end to the edge of the retaining ring 23 to swing horizontally in and through the open segment of the ring, it being normally held yieldingly in against the periphery of the cover disc 32 by the action of expansion spring means 62 supported on a stem 63 slidable at one end through an upstanding bearing lug 64 fixed to the plate 22 and secured at its other end in an upstanding lug 65 pivoted to the top face of the finger 61 adjacent its outer edge.

The finger 61 has a width appreciably greater than the width of the exposed zone of the carrier disc 25. Its top face is fiat and lies flush with the top face of the cover disc 32. Along its inner edge the underside of the finger is recessed to provide a runway 66 for the passage of coins beneath the finger, having a rear wall or shoulder 67 which is sharply curved throughout extent of the finger and which merges into a bill 68 at the free end of the finger. This bill portion extends between the associated cover discs and star wheels of the separator and countmechanisms, as seen best in Figure 2.

In the operation of the mechanism shown in Figures 1 to 9 a number of coins, tokens or the like to be counted are fed into the hopper 26 and the power shaft is actuated to set the machine in motion. By virtue of the sloping walls of the hopper the coins will slide flatly onto the rapidly rotating cover disc 32 which moves counterclockwise with respect to Figure 2. Under the action of centrifugal force the coins 31 will be thrown outwardly beneath the hopper base plate 28 into the circular guideway 30, the neck 29 of the hopper acting to strip off coins which may be stuck together. As the coins come into alignment with the discharge channel 38 in plate 28 they will be"thrown outwardly by centrifugal force onto the exposed area of the carrier disc 25. As the coins contact the rake-off arm 41 they are directed through the discharge channel and pass beneath the portion 43 of the, rake-oil arm which flattens themon the carrier disc.

As the coins on the carrier disc reach the presser finger 61 they enter the guideway 66 beneath the finger and contact the curved shoulder 67 thereof.- The" finger yields against action of spring 62 surficiently to permit free travel of coins but the tension of the spring is such that the coins will be forced in by the finger to a positive seating in the recesses of the star wheel 33. The bill portion 68 of the finger holds the coins in the starwheel 33 until they engage in the recesses of the counter star wheel 44 which has been set by proper adjustment of the frame 53 so that substantially half of the coin lines in each opposed star wheel recess as the coin passes therebetween on the face of the carrier disc, which face is so constructed that no slippage can occur.

As the coins pass successively between the star wheels beneath their cover discs the counter actuator shaft is given a step by step rotation to register the passed coins on the mechanism 50. Too great a rotation of the counter star wheel is prevented by the arm 59 and reverse movement is rendered impossible by the dog 5'7.

' After the coins have been counted they are carried along on the carried disc into engagement with a deflector 69 which guides them through a port in the ring wall 23 into a collector tube '7 leading to receptacle means, not shown. I

'In Figures 10, 11 and 12 is shown a structural embodiment of means which is intended for use in connection with the mechanism previously described for continuously agitating coins at and adjacent the point of discharge onto the carrier disc in order to eliminate the possibility of coins sticking thereatv and jamming in the machine. Throughout Figures 1 to 12 like parts are indicated by like reference characters.

In this embodiment the neck 29 of hopper 26 adjacent the discharge channel 38 and for some distance on each side thereof is cut away to provide an open segment '71, Figure 12, through which is adapted to be oscillated a flat arcuate arm '72 pivoted by one end as at '73 to an annulus '74 attached to the under face of the hopper base plate 28 at one side of the coin discharge channel 38. The arm '72 may be pivoted directly to the base plate if desired. Oscillatory movement is imparted to the striker arm '72 through a link '75 pivoted at its ends to the striker arm and a crank '76 fixed to an operating shaft '77 journalled be tween the base 20 and'plate 22 and driven from the shaft 24 by means of a belt '78 connecting a drive pulley '79 on shaft 24 with a driven pulley on shaft 77.

In order to adjustthe discharge channel 38 to different widths for coins of various sizes the .striker arm '72 has pivoted to its under face an adjustable guide finger 81 which has a tight pivot connection so that it will be retained in positionas set. The finger 81 may be turned and adjusted to vary the width of the entrance to the coin discharge channel.

In operation the throw of link'75 causes a continuous oscillatory vibration of the striker arm '72 which forcibly contacts coins on the disc 32, flattening them and loosening stuck coins so that there can be no jamming of the machine. Figures 13 and 14 illustrate an adapation of the invention. to the automatic distributionv of coins 'into standard packages with selective means for effecting a variation in the number of coins distributed. Parts identical with those previously described are given like reference characters.

In this embodiment the drive spindle 46 which operates through the pinions 48 and 49 to actuatethe register 50 on the saddle bracket 51 as the counter star wheel 44, its cover disc 45 and the toothed wheel 47 are rotated. is provided above the wheel 4''! with a squared portion 82 upon which slides the hub 83 ofa double gear having an upper gear 84 of twelve teeth and a lower gear 85 of fifteen teeth, the whole bein adjustable on the spindle by a set screw 86, in the hub. At one side of the spindle 46 a second spindle 87 is mounted in the frame 52-53 for free rotation and has fixed thereto a sixty toothed gear wheel 88 adapted to be meshed with either gear 84 or 85 depending upon adjustment of the hub 83.

A half segment of the large gear 88 is provided adjacent its periphery with an upstanding cam riser 89 which under rotation of the gear engages the short arm 90 of a bell-crank lever coin switch pivoted as at 91 on the retaining ring 23 above the foot plate 22 in a manner whereby its long arm 92 is swung laterally outward of the retaining ring to open a coin discharge port 93 therein which it normally closes under the influence of a retracting spring 94 connected be tween the short arm 90 and a lug 95 on the exterior of the retaining ring 23. A coin deflector 96 secured to the ring projects inwardly through the port 93 a short distance over the edge of the coin carrier disc 25 in substantially parallel relation to the deflector 69 which is spaced therebeyond. The inclined face of the deflector 96 provides a seat for the free end of switch arm 92, acting as a stop means to limit inward swing of the switch arm under action of the spring 94. A coin collector tube 97 is disposed at the discharge port 93 and a second collector tube 98 is disposed adjacent the discharge port at the deflector 69.

When it is desired to separate coins into groups of forty, as for instance nickels into two dollar groups, the mechanism is set as shown in Figures 13 and 14, with the fifteen toothed gear meshed with gear 88 and the end of cam riser 89 just in advance of the short arm 90 of the coin switch. Upon actuation of the mechanism gear 88 rotates in a counter-clockwise direction; the cam 89 engages the switch arm 90; and the arm 92 is swung outwardly to open port 93. As the coins pass between the main and counter star wheels they are thrown by centrifugal force through port 93 into the collector tube 9'7. Due to the gear ratio as the forty-first coin passes to the star wheels the cam 89 clears the arm 90 whereupon spring 94 snaps the arm 92 back against its seat 96 to close port 93. The forty coins following will pass around on the carrier disc 25 to be discharged by deflector 69 into the collector 98. As the eighty first coin actuates the counter star wheel the cam '89 again engages switch arm 90 and the operation is re-- peated. Coins may be packaged as desired from and with respect to the collector means 9'7 and 98. For "separating into groups of fifty the twelve toothed gear 84 is meshed with gear 38. The cycle of operations is otherwise the same as that described. By the cooperative action of the coin switch and cam the coins are automatically grouped as long as the machine operates.

Figures 15, 16 and 1'7 illustrate an attachable co-in feed hopper adapted to be used with the mechanism of Figures 1 to 14, having means for. regulating the rate of coin feed and for insuring an even flow to the machine.- Such a construction comprises an auxiliary hopper 99 of greater capacity than the machine hopper 26 ovenwhich it is supported in spaced relation therefrom by standards 100, one of which isshown Figure 15 detachably connected to the hopper. base plate 28. The neck 101 of the auxiliary hopper is concentric with the neck of hopper 26 and has substantially a quarter segment thereof cut away .As a means of regulating the rate of discharge through this port into the hopper 26 there is provided a sector shaped closure plate 106 slidable circumferentially on the exterior wall of hopper 99 and guided by bolts 10'? on the hopper engagedin s.ots 108 in the plate. The bolts are headed to overlie the edges of the closure plate slots so that they may be tightened to clamp the plate in a set position. The bottom edge 109 of the closure plate coincides With the hopper neck 101 so that the plate may be moved across the port 102 to open and close it to the degree desired for a certain rate of coin feed to hopper 26.
