Claims. (Cl. 226-14) This invention relates to counting machines for coins, tokens, and the like, and has for one object to automatically wrap a predetermined number of such articles of a selected denomination or value.

A further object is to provide means by which the counting mechanism is set into operation by the presence of an empty wrapper in wrapping position. The counting mechanism then counts and deposits a predetermined number of coins or other articles in the wrapper.

Still another object is to provide a machine wherein after the predetermined number of articles have been deposited in the wrapper, the wrapper will be auto matically closed.

A further object is to provide a machine which will stop automatically after the wrapper has been closed, and provided that no empty wrapper is in position to receive the next counted wrapper load.

Further objects and advantages will appear from a description of an embodiment of the invention shown in the accompanying drawings in which Figure 1 is a side elevation of the machine.

Figure 2 is a fragmentary top plan view of the same.

Figure 3 is a front elevation of the same.

Figure 13 is a wiring diagram of certain of the control mechanism.

Referring first to Figure 1, at 1 is indicateda'stand adapted to be supported on a table 2. This stand 1 is provided with a horizontal turntable 3 carried at the upper end of a rotary shaft 4 having a spiral gear 5 at its lower end. Meshing with this spiral gear 5 is a spiral gear 6 on a horizontal shaft 7 which carries a pulley 8 connected through a belt 9 with the drive pulley 10 of a motor 11.

This rotary table 3 forms the base of a cylindrical receptacle 12 into which coins, or tokens, or the like, are supplied from a hopper 15. By the rotation of the table 3 the coins are caused to pass outwardly by centrifugal force through a passage 20 (see Figure 2) along which they are projected by the rotation of a drive wheel 21 provided with a rubber tread 22. By rotation of this wheel 21 the coins or tokens are pushed past a serrated counting wheel 23, causing this wheel 23 to be rotated through a predetermined angular extent by each coin o token which is passed thereby. I

This counting wheel 23 is provided with a pinion 24 which meshes with peripheral teeth 25 of a counting disk 26. This disk 26 is carried by a shaft 27 and is held up into meshing relation with the pinion 24 by a gear 28.

The gear 28 is adjustably positioned in a slot 29 in an arm 30 which is pivoted for up and down swinging motion on a pivot 30a (see Figure 2).

The disk'26 is provided with one or more depressions 31 therein, which in one or more angular positions of the disk, come under an abutment 32 carried by the arm 30 and in this position the arm 30 may drop from a position elevated by reason of the member 32 riding on the disk 26, into a lowered position. The size of the disk 26 is so chosen that it makes one or a desired fraction of a revolution by the passage of coins past the counting wheel 23 during the time that it takes to count a predetermined number of coins or tokens which it is desired to package in a single wrapper, and disks of various sizes and with depressions 31 variously arranged may be employed in accordance with the number of coins of any particular denomination which it is desired to package in one wrapper. The arm 30 is normally pressed downwardly as far as is permitted by the member 32 riding on the top face of the disk 26, as by a spring 310. It normally rests upon the upper end of a rod 33 (see Figure 3) pivoted to one end of a lever 330, the opposite end of which is pivoted to a link 34. This link 34 is pivoted at its lower end to a lever 35 (Figure 9) which carries a follower roll 36 riding on the periphery of a cam 37. This cam 37 is fixed to a horizontal shaft 38 and has a lobe 39 thereon, which, in one angular position, engages the follower 36, lifting the lever 35 and raising the bar 30 so that the abutment 32 is lifted out of the depression 31 when it is desired to restart the feeding; and counting of coins.

This shaft 38 is driven through a clutch of the Horton type from a gear 40 journaled on the shaft and provided with a stop pin 42 with which cooperates a pin 43 carried by a lever 44. The gear 40 is arranged to be rotated at a slow rate of speed by means of a worm 50 carried by a vertical shaft 51 (see Figures 1 and 9). The upper end of the shaft 51 is provided with a bevel gear 52 which meshes with a similar gear 53 on a horizontai shaft 54, and a pulley 55 carried by this shaft is connected by a belt 56 to a pulley 57 carried by the shaft 7. Thus the gear 40 is driven continuously from the motor 11 and whenever the Horton clutch is tripped by depressing the left hand end of the lever 44, the shaft 38 is rotated for asingle revolution. The lever 44 is normally held in stopped position as by a spring 60 as shown in Figure 9.

The start of rotation of the shaft 38 acts to lift the lever 35 and rock the arm 30 so as to free the counting disk 26 for rotation. At the same time the feed wheel 21 is allowed to begin its rotation, the lifting of the arm 30 acting through a link 65, lever 65, and a link 67 (see Figure 3) releases the stop pin 63 of a Horton clutch 69 in the drive for the wheel 21, which is produced through rotation of a shaft 70 (see Figure 1) through a belt drive 71 from a pulley 72 carried by the shaft 7.

From the counterwheel 23, the coins are caused to pass into a chute to the packaging mechanism which constitutes the novel portion of this machine. The table 2 which supports the shaft 38 and the parts carried thereby also supports a table on which is pivoted to rotate about a vertical axis, a turret 101 (see Figure 8). turret is provided with an annular recess 102 in its lower face concentric with the turret pivot, and the turret is provided, as shown, with four open topped receptacles 112, which may be brought in succession into each of four stations where operations, as will later appear, are carried out. 1

The turret 101, as shown in Figure 8, is fixed to a vertical shaft to the lower end of which is pinned a ratchet wheel 116. Above the ratchet wheel 116 there This is journaled on the shaft 115 an arm 117 carrying a pivoted dog 118 which may engage the teeth of the ratchet wheel 116 and turn this ratchet wheel when the arm 117 is turned in one direction, the dog slipping past the ratchet teeth as the arm 117 is turned in the opposite direction.

Fixed to or integral with the arm 117 is a pinion 120 with which meshes the teeth of a rack member 121. This rack member 121 is guided for longitudinal motion and is provided at its rear end with a cam follower roll 122, which rides in a cam groove 123 in a cam disk 124 keyed to the shaft 38. This cam groove 123 is eccentric to the shaft 38, as best shown in Figure 8, so that by rotation of the shaft 38, the rack bar 121 is moved alternately axially in opposite directions. As it is moved from the position shown in Figure 8 to its opposite position, so that the rack bar is pulled to the right as shown in Figure 8, the dog 118 engages the ratchet teeth of the wheel 116 and turns the shaft 115 on the turret 191 through one-quarter of a revolution, while during the motion of the rack bar to the position shown in Figure 8, the turret remains stationary, and during this time certain operations are performed as will later appear. A spring pressed latch 125 engaging in a corresponding notch 126 in the edge of the turret 101 tends to retain the turret in any indexed station.

As before noted, there are four stations for the turret. At station A shown in Figures 4, 6 and 7, the operator may place in a liner 13! in the corresponding receptacle 112 a tubular wrapper 131, the lower end of which has been partly closed off as by being curled inwardly as shown at 132 in Figure 6. Various liners 130 may be employed, depending upon the sizes of the coins or tokens to be packaged, and each is provided with a central opening of the proper size to receive the wrapper. As this wrapper is pushed into the liner, it depresses a spring pressed plug 135 mounted in the table 100 and closes a microswitch 136 (Figures 6 and 7).

As shown best in Figure 13, there is provided a second microswitch at 137 which is closed when the arm 30 is in its depressed position and when both are closed a circuit is established from a source of power 138 through the microswitches 136 and 137 and energizes a solenoid 140. The energization of the solenoid 140 lifts its armature 141 (see Figure 9) and rocks the lever 44 in position to withdraw the stop pin 43 from the Horton clutch pin 42. This first starts the rotation of the cam 124 and effects an indexing motion of the turret, moving the receptacle into which the empty wrapper was placed from the starting station A to the filling station B. As it reaches the filling station, a cam lobe 145 on a cam 146 carried by the shaft 38 (see Figure 9) depresses the right hand end portion of a lever 150 fulcrumed at 151 and lifts its end portion 152, causing a plunger 153 slidably guided vertically through a bearing 154 to be lifted. The base of this plunger 153 engages the lower end of the unfilled wrapper and pushes the wrapper up into the flaring lower end of the chute 80 in position to receive the coins discharged from the counting machine without possibility of their failing to enter the wrapper.

At about this time, also, the arm 30 is lifted and the Horton clutch for the feeding wheel 21 is released, so that the counting mechanism begins to operate and feeds the coins into the wrapper. This action continues until the desired number of coins have been fed into the wrapper, whereupon the arm 30 is allowed to drop, the abutment 32 then being over the counter wheel depression 31, whereupon the counting and feeding of the coins stops.

At the same time that one of the wrappers is being filled with coins, a filled wrapper previously in the loading position has been moved over to the crimping station C. At this station, as shown in Figure 10, the rotation of the shaft 38 has caused a cam 160 to depress the adjacent end of a lever 161 fulcrumed at 162, against the action of a spring 163. The rocking of this lever lifts a plunger 165 at station C and causes its roughened upper face 166 to engage and lift the filled wrapper into contact with a rotary crimping tool 170. This crimping tool 170 is continuously rotated, being driven from the shaft 57 by suitable belt connections at 172. The lower end of this crimping tool, as shown best in Figures 10, ll and 12, is formed with an annular crimping recess which takes over the upper end of the wrapper and curls it inwardly in the manner shown in Figures 11 and 12, the wrapper being fed up against the tool as it is rotated to effect the crimping.

At the same time that the crimping of a filled wrapper is being accomplished, the wrapper which was previously filled and crimped and was moved from the station C to the station D in Figures 4 and 6, is moved into registry with an open tubular portion 171 to the table 100 from which it is directed as by a chute 173 to a trough 174. The wrappers reaching the trough 174 have thus each been filled with the desired number of coins, tokens, or the like, and sealed by the crimping mechanism.

The provision of the microswitch 137 insures that the full number of coins has been fed into the wrapper before the turret is indexed, even though the micro switch 136 may have been closed earlier by the placement of an empty wrapper in position at the loading station A.

In operation it is only necessary for the operator to supply empty wrappers at station A, whereupon after each supply the turret is automatically indexed to present the empty wrapper at station B where the wrapper is filled, the previously filled wrapper is moved from the station B to the station C where the wrapper is crimped to seal the coins therein, and the previously sealed wrapper with its supply of coins is moved to station D and discharged from the machine.
