(oreal-zia) My invention relatestoV a coin-wrapping machine, and the object is to provide such a machine that will rapidly and securely complete the work ofwrapping coins in packaged rolls, and in a semi-automatic manner. Y v

Parts of this machine may be so adjusted that rolls of any denominations of coins may be handled in batchesy of one such denomination' ata time, and'co'ntinuoscoinwrapping runs made for that particular denomination.

A further object isl to facilitate handling of large quanfk tities of any one denomination of coins in a time-saving manner, and in my invention the machinery to accomplish this is extremely simple in comparison with conventional coin-wrappers, and it may be' manufactured very economically when compared with other machines for similar purposes. Y

This machine is compactly composed as to its various' parts, and as illustrated and hereinafter described is slidably activated by hand. or lit may be readily electrically driven by a motor by the' addition of a few necessary parts.

In the drawings the numeral 1 refersy to each of two upright side plate members supporting the machine, to the top longitudinal edge of each of which is afhxed a channel sectioned member 2 with llanges facing inwardly ofthe machine. The ends of this supporting frame are closed by transverse plates 3 and 4 with the exception that the one at the feed-in end to the left in Figure i '2,823,504 #atenten Feb. 1s, 19 5s ICC 1 where the top efdgjiisjsp edjbelgw'lthe xtop ler/'e1 of the' side"chanriels,- and alsotliat the p1ate4`a'tthedischarge opposite' end the-bottom edge" of this plate'I is spaced abbi/"6l the 'bottom of the machine; through which' space wrapped coins are tb'e discharged. I

The roll of coins 5vy in this coin-wrapping,machineis placed transverselythereof,`v arrdfrestsfon atleast three transverse rollers 6 covered with"deformablematerialL Betweenv coin'and rollers acoin-wapping sheet of paper 7 is inserted a'twis'e passing from autray4 8 supported on' transverse plates 9bridging the' side`v platesA 1. The coins` are1 held erect during wrapping; andia'l's'o held in place, by adjustablej transversely disposed rods- 10an'd are braced between; thesei'tyvo'rod's, therods being" bear' ably mounted in bl`ocks11`on`one' side member andv 11a on the other side' member, attached 'toth'e outer faces thereof. Thesev samei'ro'dstpass threalablyv into' blocks 12 and 12a respectively` andfraceonthe' said blocks 1'1" and 11h, and have adjustable' nuts; ,13o`yn' their outer ends. Adjustable slidable" barsi 1'4' for the support of the: rollersV 6 are slidablyv mountedv ih slotted arcular shaped keeper membersv` 1""5l yattached to' th`e` innerfaces of' the side membe'rsl; Pressureisrnaintained betweenJ rollers' 6 and thepaper-enelo'sed coin' roll 5 by means ofv springs lio enclosingrods 17 entending'from eachsa'id' bary 14. The enids': of thesfe'rrodsZ are supported in apertu'redl brackets' 1'8- attacl'l'edf"to thefinel" faces? of Sides" 1. Nuts 19 on the' ends' of these' rods are the adjusting' members therefor, 7

With the coins cradled" on the rollers' the parts for wrapping the paper th'e'e'arund consist 'o'f aV carriage' plate 20` indirectly snpp'or dontr'ansverse bars'- 21`, 22, and 23, each said bar having'v a free trhing'roller 24' atl itsyen'ds. These endrolle'rs1 travelin tracks 25 which are aied outboardlyand wi'thinthe channel members 2 to` the top edges of the side walls l1,.' As` the carriage as'- sernbly plate `Zllrr'loves* from ,right 'to'l left (Figures 1 and 2) Aa paper-starting plate 26' cornesir'fco'ntact with the extending erid of the paper 7l nearest to theV coins in place ont'h'e rollers 6, and carries; same over the coin roll 5. The movementvof the carriage is accomplished by gripping a handle 27 mou'nted on top of the bar 23 and braced by a bar 27a on tothe bar' 22.

The coactivating mechanism in the wrapping process consists of a free turning roller 28 atta'hedpe'rpendicillarly toy an arrn 28a attached to the spindle of the roller 28 and mounting same, the roller running on top of one of the channel inenibers"V 2. The other-v end of this arm 28a is attached to a transverse shaft 29'Y supported on two blocks 30 on the saidtransverse bar 21. Two paper-4 starting plate bars 31 are aixed to the cross shaft 29 and swing with it together with the arm 28a, and the roller 28 rides up and down the track of a ramp 32 mounted also on this same side channel member 2. The said ramp is pivoted by a pin 33 mounted on this side member, and as roller v28 contacts'` the ramp this actuates the starting plate bars 31, each plate bar having an associated thrust spring`34t enclosing a rod 35 passing down through it towards and connecting withv the said paper-starting plate 26, which is therefore in indirect connection with the bars 31. These rods 35 are slidable within the heads of the bars 31. As the carriage is carried further to the left (Figures l and 2) the carriage plate'20 comes in contact with the coin roll 5 now covered in readiness with the paper 7, which paper is held firmly' and closely against the coin roll: by the action of the springs 34 pressing down on the paper-starting plate 26. The carriage plate 20 forces the 'coin' roll against the bed rollers 6, and by friction causes the roll to rotate in an anticlock'wise' directionas referred to" 3. Figure l, thus wrapping the paper tightly around the roll of coins.

At this time the free roller 28 oversteps the forward edge 32a of the ramp 32 and drops to a starting position on top of the channel 2 on the ramp side, which action raises the paper-starting plate 26 back to its original position, the paper having made one complete` turn to encircle the coins, and the said plate has completed its purpose.

As the right to left movement is continued the whole of the sheet of paper has been wrapped around the coins, and at this point a free wheel 36 on a point-retracting rod 37 assembled with blocks 11 and 12 on the one side of the machine contacts a plate 38 supported on the

bars

20 and 23, which plate has a bevelled end 39 at its front end. This action forces the free block 12 to the right or away from the block 11 (Fig. 9).

With reference to the travel of the roller 28 relatively with the ramp 32, as soon as the roller passes over thel end 32a of the ramp, it returns under the ramp, lifting a hinged end portion thereof 32b. The hinged end then rests normally in place on the top of channel 2 after the passage of the roller thereunder.

A threaded gear rack 40 (Fig. 9) is attached to this free block 12 and rotates a fixed gear 41 which causes a gear rack 42, attached to the free block 12a, to move outwardly away from the frame, and thus withdraws the coin-supporting rods so that they are clear of paper folding rollers 43. Plates 44 supporting these rollers are adjustably mounted on the rear or right end of the carriage by means of pins 45 slidable in slots cut in these blocks 44. These rollers therefore turn freely in relation with the said blocks 44. The rollers turn freely in holes in the blocks and are attached to the carriage plate 20 by means of pins 45, said pins being slidable in slots cut in the said blocks.

As the carriage 20 continues to travel from right to left the paper folding rollers 43 come in contact with the ends of the paper sheet which ends protrude from each side of the coin roll. (The said rollers are spaced one third of the circumference of a coin roll), and are folded very tightly against the ends of the roll in three folds on account of the set revolutions of the coin roll and the exact positioning of the folding rollers 43. YTeusion springs 46 are disposed between the blocks 44 which supply the necessary pressure to insure this tight folding action, and also suflicient expansion to providefor a longer than average coin roll, which might possibly be the case due to new or thicker coins than are conventionally in circulation. Y

As the carriage 20 travels still further to the left its plate passes over the securely packaged coins, and an inked rubber stamp 47 automatically contacts the roll for name printing etc. At this point the carriage-has reached its limit of travelled distance and is ready for the return to its starting position again. In this returning action the springs 16 force the packaged coins up, and as the carriage is moved to the right (Figures 1 and 2) the packaged and stampedcoin roll is pushed from the coin bed rollers 6 and rolls down ithe curved face of a chute 48, and discharges through an opening at the bottom of the end wall or plate 4, this opening being shown at 49. As the return of the carriage begins a free roller 50 (Figure 12), attached to a crank arm 51 on a shaft 52 contacts a ramp 53 attached to one side member of the frame plate 1, the ramp being hinged by a pin S4 for said attachment and overbalances thereon. The shaft 52 is bearably supported on two blocks 55 mounted on the carriage 20. This contact forces a rubber paper finger'56 down through an aperture 57 in the carriage plate 20, and one sheet of the paper is drawn from thetop of the paper stock 7 on the tray 8, and is carried over the roller bed 6. As the roller 50 passes beyond the ramp 53 this rubber paper finger 56 returns to normal position as roller S0 slides down the ramp again, thus releasing paper in a correct position for reception of the next roll of coins.

As soon as the bevel edge of 38, that is the point 39, withdraws from the wheel 36 tension springs 5S connecting the two blocks 11 and 12, and also the two blocks 11a and 12a, draw each coin-supported rod 10 back to its original position. As the carriage 20 completes the return movement to the extreme right position (Figures 1 and 3) the rubber stamp 47 contacts an inking pad 59 which is mounted on the coin-delivery end of the machine body, thus inking said stamp in preparation for the next roll on the movement of the carriage leftwise. Finger S6 is spring loaded by means of bow spring 60 -anchored to block 55.
