The paper 25' for the diiferent denominations of coins is'wound' in rolls on hollow spools 26, any one of which is adapted to' be centered on a rotatable support 27 by inserting the upstanding pin 28 thereof in the hollow of said spool. (See Fig. 3.) The width of the paper strip or web determinesthe length ofthe package andbecausethese widths vary" with the diiierent denomina tions of coins, means are provided for vertically adjusting. the support 27 so that the center of any one ofthe strips or webs will be aligned with the center of the feed roller and the vertically disposed packaging rollers hereinafter referred to.

The means for vertically adjusting the support 27 and* 2,693,956 Patented Nov. 9, 1954 consequently the roll of paper mounted thereon is shown in. Figs. 1, 4, 10' and 11-. Referring to these figures,- the apparatus includes a base plate 29,= and a horizontally disposed shelf plate 30 supported from said base plate'by uprights 31. The support 27 includes a centrally disposed pivot shaft 32 suitably journalled in the plate 30 and bearing at its lower end on a vertically disposed adjust able shaft 33 which is loosely slidably mounted at its lower end in the transverse portion of a yoke 34 whose legs are secured by screws 35 to the bottom of the" plate 30. The shaft 33 has a threadedportion 3'6 mounted in a threaded collar 37 having anarm 38 carrying a pin- 39 on which rollers 40 are mounted in spaced relation; Ari-initial vertical adjustment between; the shafts 32 and 33 can be made by turningthe shaft 3-3, from its lower slotted end, in the collar 37. The rollers 40 bear upon spaced wedge shaped cam bars 41 suitably connected together at their ends to form a wedge member slidably mounted on a pin 42,- carried by the yoke 34, and connected at one end to' arack bar 43' which isv slidably mounted and guided and held in operative relationwith a rotatably adjustable gear 44, Fig. 4, by a member 45 suit-ably anchored to the plate 30'.- Turning of the gear 44 by turning of acontrol shaft 46 on which it is mounted moves-the rack bar 43 and consequently the shaft 33 up or down to adjust the vertical position of the support 27 relative to the shelf 30 so as to bring the center of the paper web into alignment with the center of a feed roll 47, Figs. 1 and 4, from which the paper is fed to the wrapper cutting mechanism.

An oscillatory resilient ended brake member 48 bears on the web to hold it from unwinding.

The feedroll 47 ismounted ona vertically disposed shaft 49 journal'led in an upper shelf plate 50; and in a bottom bearing member 51 supported on the shelf plate 30 and carries a hand wheel or adjusting knob 52. As shown in Figs. 1, 15 and 1-6, a drive pulley 53, for the shaft 49 is operatively connected thereto by a ratchetwheel- 54, pinned to said shaft and engaged by a spring pressed pawl- 55 pi-votally mounted onthe pulley so that the shaft 49 may be turnedby the knob 52 as well as y e p y -3. v

Referring to Figs; 4,- 7 and 12 to 14, the pulley 53 isconnected by a belt 56 with apulley 57 onthe main drive shaft 58 for the Wrapper forming mechanism and also the packaging mechanism more particularly shown and described in the application Serial No. 64,574. Shaft 58 carries a gear 59 meshing with a small gear 60 on ashaft 61 which carries alarge gear 62 meshing with a small gear 63 on a cone clutch member 64 adapted to engage acooperative clutchelement 65 on a shaft 66 carryinga pulley 67 connected by abelt' 68 to a-pulley 69 on the shaft 70 of an electric drive motor- 71-. Shaft 66 has a shaft extension- 72 carrying a pulley 73 connected by a belt 74 to a pulley 75 ona shaft 76 that drives the wrapping rollers of the aforementioned application: Spring actuated tensioners 77, 78, and 79 are provided respectively forthe belts 56, 74 and- 68'. Since the shaft- 58 is connected by gears to the clutch member 64 and by the pulley and belt drive noted above to the feed' rollshaft 49 whenever this clutch member is engagedwith' the clutch element 65, the shaft 49 will be driven from the motor 71'.

As in: the aforementioned application, the cone clutch member 64 hasa collar 79 journalled on it and carrying diametrically disposed pins 80 which engage the forked portions 8 1 of alever 82 pivoted at 83' and carrying. at'its outer end aheaded rod 84 which is slidably-mounted insaid lever and normally moved against the same by a spring 85, the head 86 of said rodbeing pivotally con nected by a pin 87 to a solenoid plunger 88 which works in asolenoid core 89 mounted with; itscoil 90 ina'housing 91. A red 92* slidably mounted in the housing 91 is urged by a spring 93' into engagement with the lever 82 so; as to move the same and the clutch member 64 to aclutch release position. The solenoid plunger 88 acting through the spring on the lever 82 moves clutchmember 64 to engaged position against the tension of the spring 93 when the coil is energized.

The-paper web; asitpasses the feeding roll- 47,- is-pref-i erably creased along a center line so as" to forma stifieningrib 94 in it, and for this purpose the roll 47 is provided with a centrally disposed annular V-groove 95 with which a conically formed creasing roller or roll 96 cooperates, said roller being rotatably mounted on a swingable arm 97 carried by a shaft 98 which has another arm 99 acted upon by a spring 100 to normally hold the roller 96 in contact with the paper web and thus permit the feed roll 47 to feed the web forwardly to the packager, but when as in the present case the roller 96 is swung away from the roll 47, the feed of the web stops even though the roll 47 may be rotating, see Figs. 1 and 5 to 7.

For releasing the roller 96 from paper feeding engagement with the paper, a plunger type solenoid including a coil 101 has its plunger 102 connected by a link 103 to a bell crank lever 104 pivoted at 105 (see Figs. 5 to 8) to the frame and carrying a tappet 106 adapted to engage an adjustable tappet screw 107 on the arm 99. The coil 101 has circuit connections hereafter described, one of which includes a web controlled switch 108.

Referring to Figs. 1, 3, 5 and 6, the paper web from roll 25 is threaded between a roller guide 109, plate 110 and a back plate 111 before it contacts the roll 47. The paper web for each coin denomination is provided with a series of holes 112 equidistantly spaced lengthwise thereof and these holes permit the actuating arm 113 of the switch 108 to move to switch closing position, this actuating member being free under these conditions to move through alined slots 114 and 115 in the plates 110 and 111. In each instance the distance between the holes 112 for any given denomination is equal to the length of this cut blank along its center line. The closing of the circuit through the solenoid coil 101 moves the roller 96 out of feeding engagement with the paper as previously described to stop the feed of the web by the roll 47. As the spacing of the holes 112 in the web vary with the length of the blank for any particular denomination of coin, means have been provided for adiustably positionin the switch 108 relative to the web or the feed roll 47. The housing of switch 108 is slidablv mounted on horizontally positioned support rods 116 back of the plate 111. said housing having a slot 117 receiving the rounded end of a lever 118 pivotally supported at 119 and having a roller 120 normallv urged by a s ring 121 against a multiple faced earn 122, see Fig. 6, having cam segments lettered D. P. N, O. H es. pennies. nickels. u s an h lf dollars). Cam 122 is mounted on a shaft 122a carrving a gear 122b which meshes with a se mental ear 1220 mounted on the manually settable shaft 46 which carries a hand crank 46a having a pointer 46b working over a dial plate rovided with D, P. N. O and H indicators shown in Fig. 3. Thus the positioning of the switch 108 for any particular wra per web denomination is carried out simultaneouslv with the positioning of the support 27 for that denomination.

The creased web is advanced by the feed roll 47 past the cutting mechan sm bv the amount of feed suited to the coin denomination to be wra ed to cut the web into the wrapper blank B, shown on Figs. 23 and 24.

The cutting mechanism. its adjustment. and drive means are similar to that of the aforementioned application and is shown in Figs. 2. 3, 5 and 9 and includes a V-shaped knife 123 cooperating with a V-notched knife plate or die 124 to cut the web into wrap ers B, each havin a pointed front end 125 and a notched rear end 126. The cutters 123 and 124 are mounted for lengthwise adiustrnent in fixed su ports so as to position them to cut the web to the desired denomination len th. The knife 123 is mounted on a frame 127 which includes spaced lower tubular bracket members 128 slidably mounted on a fixed horizontally disposed lower guide bar 129 and a grooved bracket member 130 slidably mounted on a fixed horizontally disposed upper guide bar 131. A rack 132 is secured to the bracket members 128 and meshes with a gear 133 on a vertically disposed shaft 134 journalled in hearings in the plate 30 and carrying a gear 135 meshing with the gear 44 on the control shaft 46, the ratio of the above gearing being such that the knives are moved lengthwise proportionately to the lengthwise feed of the paper web so that this web will be cut into blanks whose lerlilgth7s are equal to the feed of the web by the feeding r0 4 For reciprocating the knives or cutters 123 and 124 relative to each other the frame 127 carries vertically spaced horizontally disposed arms 136 secured at the end directly thereto, see Figs. 5 and 9. The knife or die 124 has spaced arms 137 provided with collars or bosses 138 slidable on rods 139 which are fixed to the arms 136 and to the frame 127. An oscillatory shaft 140, journalled in ipied bearings 141 and 142 and of the polygonal form (shown in cross section in Fig. 9) between said bearings and providing a lengthwise extending crank arm 143, has an operating crank arm 144 secured to it at one end. The outer end of arm 143 is slidably movable in a slot 145 in a part 146 projecting from the knife 124 so that said arm is effective for reciprocating said knife in any position of its lengthwise adjustment. The crank arm 144 is intermittently operated in synchronism with the web feed mechanism by a link 147 operatively connecting it with a crank arm 148 on a shaft 149 journalled in bearings 150 and carrying a cam operated crank arm 151 provided with a roller 152. Roller 152 is engaged by a cam projection 153 on the gear 59, fixed to the shaft 58, as said gear revolves in the direction of the arrow shown in Fig. 4 to raise said arm 151, and oscillate said shaft 149 and lower the arm 148 which through the link 147 swings the arm 144 in a clockwise direction and causes the crank 143 to act on the part 146 of the knife 124 to push it outwardly toward the left, as viewed in Fig. 9, so that the web of paper between the cutters 123 and 124 is cut. Shortly after this cut is made, a cam projection 154 mounted on the gear 59 engages the roller 152 to move the arm 151 back to its initial position and thus through the connection just described swing the arm 153 back to return the knife 124 to its initial or spaced position relative to the cutter 123.

Referring to Figs. 3, 4 and 14, the shaft 58 has feed control cams 155 and 156 mounted thereon controlling switches 157 and 158 in the circuit controlling the solenoid coil 101. The shaft 58 also carries the wrapper clutch control cam 159 controlling a switch 160 in the circuit controlling the solenoid coil 90. As in the aforementioned application, the predetermined count mechanism of the counter C controls a switch 161 (Fig. 17) in the clutch control circuit.

Fig. 17 is a circuit diagram of the solenoids and control switches mentioned above and the wrapping mechanism drive motor 71 and the counter drive motor 162. Numeral 163 designates the main supply lines connected by 1 a branch line 164 to' the motor 162 and by branch lines 165 to the motor 71 with cut out switches 166 and 167 which are closed by the operator in starting the apparatus so that the motors 71 and 162 operate continuously. One of the lines 163 is connected by a conductor 168 to one terminal of the coil 90 whose other terminal is connected to a conductor 169 having branches 170 and 171 connected to the other of the lines 163. Switch 160 is in line 170 and switch 161 in line 171. One of the lines 163 connects with one terminal of the coil 101 whose other terminal is connected to a conductor 172 to the other side of the line 163 beyond its point of connection with line 174. A hand operated switch 177 also may connect the coil 90 with the supply lines for bringing the web to a starting position.

Switch 160 is a normally closed switch so that coil 90 is energized to move plunger 88 and lever 82 and clutch member 64 to clutch engaged position for drive from the shaft 66 to drive gears 63, 62, 60 and 59, shaft 58, pulley 57, belt 56, pulley 53, shaft 49 and feed roll 47 until the cam 159 on shaft 58 opens said switch 160. As soon as the shaft 66 is engaged, the cam 153 is operated to move the knife 124 to cut off a wrapper blank from the web. The switch 161 is closed to also energize coil 90 when the clutch lever of said application is shifted to disengaged position at the end of a predetermined count and the closing of this switch takes place just before the earn 159 breaks its connection with switch 160. Feed roll 47 is continuously driven during a part of the operation of the counter, and the entire period of operation of the packaging mechanism. However, only a portion of the period of drive of the feed roll 47 is used for active feed of the web from the paper roll 25, and this period is determined by the times that the roller 96 is held engaged with the web by the spring 100. which periods are determined by the energization of the solenoid 101 to move roller 96 to non-feeding position, and this is in turn controlled by the web controlled switch 108 and the cam controlled switches 157 and 158.

Since the distance between the centers of the holes 112 for a wrapper of any given denomination is equal to the length of the cut wrapper blank on its center line, and

the actuating member 113 of: the switch 1:08 eng ing the web is held open by the.web,,then. switch 108 will be held open to cut out the coil" 1'01 and allow the spring 100 to hold the roller 96 in feed engagement with the web: while the web is traveling the distance: between the holes 112. However, since. the cut of the web to form the blank is not: made. atone of, the holes 112,. other controls. to stop the feed of the web at the desired point are necessary, and the switch 108v isused to start the: feed of thewe'b and continue this. feed until the other controls take over to finish the feed of the web a distance equal to that between the holes. Referring to Figs. 18 to 22 in each instance this feed of the web from one hole 112 towards the next hole 112 bring the front end 175 of the web to a position designated by the line X. The adjustment of the cutters through the mechanism above described is such as to dispose them at varying distances from the line X and at such a distance from a line Y to cut the particular blank denomination to the required length. The distance between the lines X and Y is the same for all blanks and the switches 157 and 158 cooperate to control the advance of the web this distance and allow the cutters 123 and 124 to operate and also hold the front end of the web at the point Y while it is being engaged by the wrapping rollers 176 of the packaging mechanism. As the web has been advanced by the roll 47 and roller 96 toward the next hole 112, the actuator 113 of switch 108 is free to drop into this hole and thereby permit switch 108 to close and energize coil 101 to move roller 96 to its disengaged position with the point 175 of the web at line X to stop the feed of the web. Shortly after switch 108 closes, the cam 155 contacts the actuating member for switch 157 and opens this switch, thereby cutting out coil 101 so that roll 47 and roller 96 under the action of spring 100 again become active to feed the web. As the web moves its hole 112 moves out from under the actu ator 113 of switch 108 so that the actuator again moves on the web surface and switch 108 is again opened so that both switches 108 and 157 are now open. The cam 155 keeps the switch 157 open until the web has been advanced from X to Y and then the switch 157 is closed again, but this would not stop the feed of the web since switch 108 is still open, but as soon as cam 155 releases switch 157, cam 156 acts to close switch 158 to energize coil 101 and stop the feed at the instant that the point 175 of the web arrives at line Y.

By the time that the web reaches Y, the previously cut wrapper blank has been fed into the wrapping mechanism of the aforementioned application, the predetermined number of coins received from the counter C have been wrapped and the counter is counting out another batch of coins. Wrapper drive shaft 58 has then stopped rotat ing because cam 159 has moved to open switch 160 and consequently open the circuit to coil 90 and thereby permit spring 93 (Fig. 13) to act to move clutch member 64 to release position, switch 161 being then in its open position as explained in said application. When the new batch of counted coins has been transferred from the counter to the coin holder of the wrapping mechanism, the web is at rest at the point Y, where its point 175 is ready to be engaged by the wrapping rollers 176, the cam 153 operates to cut off the blank to the desired length and the cut blank, then engaged by rollers 176, is fed into the wrapping mechanism around the transferred coins. While the cam 156 is holding switch 158 closed, the pre viously cut blank is being wrapped and crimoed about the coins by the wrapper mechanism, and when this cam leaves switch 158 and coil 101 is again cut out, the web is again advanced to the point or line X and the cycle is again repeated.

Due to the fact that the spacings for the holes 112 vary for different denominations and the switch 108 must be controlled by any of the webs, the positioning of this switch by the cam 122 is effected as indicated in Figs. 18 to 22. It is to be noted that this switch is spaced progressively farther and farther away from the feed roll 47 for the webs for the dimes, pennies and nickels with holes for three blank spacings while for the quarters and half dollars the positioning of switch 108 is dependent on a two blank spacing between it and the point X.

It is to be noted that in setting up the machine for packaging any selected denomination of coins the web of the wrapper supply roll must be threaded between the rolls 47 and 96, the plates 110 and 111 and between the knives 123 and 124 and brought to some point beyond the: point-X; The wrapper feed mechanism of the machine always stops in:- 321308111011- in which the'cam 159 is holding: the switch I603 open as shown in. Fig. 3, and in that position: cam 1'55 is holdi'ng. switch 157 open. Under these: conditionsthe: motor 71' is started by the closing of the: switch 1367 and the web threadedthrough as above described until its first hole 112 alines with the slot 178 in the knife bar 123. The hand switch 177 is then momentarily closed to energize coil and turn shaft 58 so that cam 159 leaves switch 160 and the web is advanced, and the cutting mechanism then makes one cycle cutting off the forward end of the web and bringing the now pointed end of the web to the point Y. The machine is now in cycle and the coins may now be introduced into the counter and the switch 166 closed to start the counting and packaging operations. The construction of the counter, its control switch 161 and the transfer tube T and its operating mechanism are as noted more gargicularly shown and described in application Serial No.

It is to be noted that the cam controlling normally closed feed control switch 157, cam 156 controlling normally open feed control switch 158, and the cutter controlling cams 153 and 154 are all mounted on and driven by the shaft 58 is definite cyclic sequence, and that since the operation of the switch 108 is dependent upon the feed of the web, the operation of this switch has a definite cyclic sequence relative to the cam controlled switches 157 and 158. To summarize the general operation of the feeding and cutting mechanism, assuming the web for any particular coin denomination has been fed to bring its pointed cut end to the position Y, indicated in Figs. 18 to 22, at this time this pointed end is in a position for engagement with one or more of the wrapping rollers 176 indicated in Fig. 3 for wrapping about a batch of coins in the coin holder associated with said rollers. At this time the solenoid operated clutch 64 is engaged and shaft 58 turning to cause cam 153 to actuate the knife 124 to cut off the wrapper blank. While the cam 153 is operating and for a predetermined period thereafter as indicated by these cams in Fig. 4, the cam 156 acts to hold switch 158 closed to stop further feed of the web and the blank just cut is being wrapped and crirnped about the coins by the wrapper mechanism. When the cam 156 leaves the switch 158, it opens and coil 101 is deenergized and rollers 47 and 46 are brought into cooperative feeding engagement with the web to advance it to the point X while switch 108 is held open by the web. Thereafter, the switch 157 is opened by the cam 155 to permit moving one of the holes 112 in the web past the switch 108 and further feed of the web to the point Y, at which time the feed is stopped by the closing of switch 158 by the cam 156. Thus a new section of the web has been presented between the knives 123 and 124 for cutting the next wrapper to be fed into the packaging mechanism.

The above described mechanism permits continuous drive of the feed roll 47 during the feeding cycle of the coin counting and wrapping apparatus while precisely controlling the active feeding period of said roll to feed the web the length of the desired finished blank.

I desire it to be understood that this invention is not to be' limited to any particular form or arrangement of parts except in so far as such limitations are included in the claim.
