WRAPPING- MACHINE.

Application fledlarch 9, 1926. Serial no. cases.

This invention relates to wrapping machines, and to wrapping methods, and mpre particularly -to a machine for wrapping coins to facilitate the handling of come in banks or elsewhere.

A more particular object is to provide a coin wrapping machine which will be simple in construction, rapid, accurate and efficient in operation, and inexpensive to manufacture. a

A further object is to provide an improved method of securely wrapping a stack of coins in such manner that the coins at the ends of the stack will be exposed suificiently to show the denomination thereof.

With the above and other objects in View, the invention consists in the novel and useful provision, formation, combination, association and relative arrangement. of parts, members and features, all as hereinafter described, shown in the drawings, and finally pointed out in claims.

Flgure 13 is an end view of one of the wrappers shown coiled twice in wrapped position; and 1 Figure 14 is a perspective view of a stack of coins wrapped with one of my Wrappers by my machine and method.

Qorresponding parts in all the figures are deslgnated by the same reference characters.

Referring with particularity to the drawings, I have shown certain devices and elements which may be used with my wrapping mechanlsm such as a sorting mechanism S, a counting mechanism C and a wrapping mechanism W for each denomination of coins to be wrapped; there being four of such units shown in the present embodiment in'Fig. 1, for respectively sortlng, counting and wrapping pennies, dimes, nickles and quarters, which units are respectively indicated P, D, N and Q.

Furthermore I have included a coin hopper H, a coin chute I inclined downwardly from said hopper, a coin feed mechanism F between said hopper and said chute, and four coin stacking tubes d, p, n and q, leading vertically downwardly from the chute I to the sorting mechanisms S of the units D, P, N and Q respectively, there being openings d, p, and n in the bottom of the chute which lead into the upper ends of the tubes d, p and n respectively while the lower end of the chute leads into the upper end of the stacking tube 9. The stacking tubes are provided with longitudinal slots (2 17 n and g for observing the coins in said The chute I is formed with four

superimposed coin guideways

1, 2, 3 and 4 for respectively guiding the dimes, pennies, nickles and quarters into the stacking tubes d, p, n and g. The guideway 1 is of a width to receive only a dime and the bottom 1- thereof is below the

guideways

2, 3, and 4, and the guideway 1 leads downwardly to the opening d, through which opening dimes are discharged from said guideway into the dime stacking tube d. The guideway 2 is of a width to receive pennies and the supporting faces 2 thereof are above the bottom 1 of the guideway 1 and below the guideways 3 and l, and said faces lead downwardly into the opening p through which the pennies are discharged from the guideway into the penny stacking tube 1. The guide-way 3 isof a width to receive nickles and its supporting faces 3 are above the supporting faces 2 of penny guideway 2 and the supporting faces 3 lead down wardly into the opening a through which the nickles fall from the guidcway 3 into the nickle stacking tube '22. The guideway 4 is of a width to receive quarters. and its supporting faces 1 are above the faces 3 of guideway 3, and the supporting faces 1 lead downwardly through the lower end of the chute into the quarter stacking tube 9 into which the quarters drop from the guideway.

The coin feeding mechanism F includes a pair of feed rollers f and f, and gears 5, 6 and 7 through which said rollers are driven in the same direction. The rollers 7' and f are journaled in bearings 8 and 9 atthe lower discharge end of the hopper H with the periphery of the roller f flush with the inner side of the rear inclined wall h of said hopper, and with the periphery of the roller f spaced slightly forwardly from the periphery of the roller 7 at a distance slightly greater than the thickness of the largest coin handled by the machine, so that the coins may pass between said rollers one by one only. The roller 7' is mounted outside the hopper with a portion of its periphery projecting through an opening it in the inclined wall it of the hopper H so that the periphery of said roller rotates flush with the inner side of said wall 71. The roller f is mounted half within the lower end of the hopper and holds'all the coins in the hop per except those passing out one by one between the rollers f and f. The gear 5 is secured on a power shaft 10 between and in mesh with the gears 6 and 7 which are secured on the journals (5 and 7 respectively of the rollers f and f. The rotation of the gears 6 and 7 by the gear 5 rotates the rollers f and 7" both counter clockwise. but the adjacent peripheral surfaces of said rollers within the hopper are rotated in opposite directions so that the peripheral surface of the roller f within the hopper will travel downwardly and feed the coins in the back of the hopper one by one between the rollers into the chute I, while the peripheral surface of the roller f within the hopper H travels upwardly and pushes all the coins back into the hopper, except those fed out by the roller 7.

The sorting mechanism of each unit comprises a slide 8 constructed with a, lower horizontal plate 11, an upper horizontal plate 12 and a vertical cylindrical sorting barrel B secured at its lower and upper ends to the forward ends of

said plates

11 and 12 respectively with the bore of the barrel extending through said plates. The slide .9 is mounted in a slideway s which consists of a flat plate 13 with its side edges 11 turned upwardly and inwardly. The slide plate 11 rests and slides upon the slide-way plate 13 with the side edges of the plate 11 fitting and sliding in the channels within the upwardly inturned edges 14 of the plate 13. The slide-way s is provided with an opening 15 in its forward end. Normally the slide S rests in a position with its barrel B directly under a coin stacking tube such as tube q. (See Fig. 2.) The barrel B is of such height as to hold a predetermined number of coins.

Each counting mechanism compris s a register R with its operating arm r connected to one end of a link 16 which is hooked at its other end into a side slide plate 12 at 16.

The wrapping mechanism TV comprises primarily a plurality of vertical wrapping rollers 'w, 'w', 10 and 10 spaced apart in a circle, and a pair of crimpers 7c and 7c. The wrapping rollers are preferably made of steel with knurled surfaces 17. The rollers w, 'w. w and 10 have

lower journals

20, 21 and 22, and a shaft 23 respectively connected to their lower ends, and said rollers have upper journals 24. 25, 26 and 27 respectively. The lower journals 20 to 22 inclusive, and shaft 23, extend through short radial slots 30 in a lower plate 31, on which plate rest the lower ends of the wrapping rollers w, w, 20 and L0 An upper plate 32 is fixed on the lower end of a vertical cylindrical throat 33 and a cam disk 34 is j ournaled on said throat and rests upon the said upper plate. The upper plate 32 is provided with radial slots 35 and the cam disk 34 is provided with a plurality of cam slots 36 which extend over the slots 35 respectively. Each of the upper journals 24 to 27 inclusive, extends upwardly through a pair of

slots

35 and 36 in the upper plate and cam disk respectively. The upper end of the throat 33 is fitted in the opening 15 of a slide-way s. The cam disk 34: is formed with an outwardly extending arm 37, to which is connected one end of a spring 38, the other end of which spring is connected to a stud 39 on the upper plate 32, so that the spring normally holds the caln disk in position with the rear ends of its slots engaging the upper journals 24 to 27 inclusive and holding the upper ends of the Wrapping rollers w, w, 'w and w in their innermost position. On the lower and upper ends of the wrapping roller w are secured the crimpers k and k respectively, which consist of metal disks 40 of slightly larger diameter than the roller w, which disks are formed in their crimping faces with a plurality of spaced radial grooves 41. Between the wrapping rollers 'w and 'w are located a pair of spaced vertical guides 42 and 43, providing an entrance space 44 there-between through which the coin wraper is introduced. A guide 45 is located etween the rollers 'w and 'w. A guide 46 is located between the rollers w and 10 A guide finger 47 is located between the rollers 'w and w A U-shaped wrapper guide 50 is provided for guiding the wrapper through the space 44 into the wrapping mechanism, Onthe

lower journals

20, 21 and 22 and on the shaft 23, immediately below the lower plate 31 are respectively secured pinions 51,

r

52, 53 and 54 which mesh with a gear 55 secured on a sleeve 56 journaled at its upper end in a conical bearing 57 in the lower plate 31. A plunger 58 extends through the sleeve 56 and has a head 59 on its upper end above the plate 31 between the rollers w, 'w, w and Q0 On the

lower journals

20, 21 and 22 and on the shaft 23 immediately below the

pinions

51, 52, 53 and 54 respectively are secured

pulleys

60, 61, 62 and 63 over which extend a coil spring belt 64 which yieldingly holds the lower ends of the rollers w, w, w and 'w in their innermost position.

On a power shaft are secured cams 71, 72 and 73 and a bevel gear 74. The bevel gear 74 meshes with a bevel pinion 75 on the lower end of the shaft 23 whereby said shaft is rotated. The cam 71 is engaged by the lower end of a lever 76, the upper end of which is connected to one end of a rod 77 which in turn is connected at its other end to the slide 8 as at 78. The cam 72 is engaged by the lower end of a lever 79, the upper end of which lever engages the cam disk arm 37. The cam 73 is engaged by a lever 80, one end of which engages the lower end of the plunger 58 while its other end is connected to one end of aspring 81 which in turnis connected at its other end to a fixed part 82.

The operation is as follows: The coins to be sorted, counted and wrapped are first thrown promiscuously into the hopperHin which they are separated and fed by the feed rollers f and f one by one into the upper end of the chute I in which the coins travel down their proper slide-

ways

1, 2, 3 and 4 into their proper stacking tubes (Z. n and g respectively; the dimes traveling through guide-way 1 and opening d into stacking tube d; the pennies traveling through guide-way 2 and opening 12' into stacking tube 1); the nickles traveling through guide-way 3 and opening 12/ into tubes drop into the barrels B of the sorting mechanisms S and fill said barrels with the predetermined number of coins.

The rotation of the cams 71 by shaft 70 swings the upper end of the levers 76 forwardly which through links 77 idraw the slides s forwardly, separating and sorting. the coins in the barrels'B from those in the stacking tubes, until the lower end of said barrels coincide with the openings 15 in the slideways s, whereupon the stacks of coins in said barrels drop through said openings and through the throats 33 into the wrapping mechanisms W between the rollers w, 'w, 'w and 10 onto the plunger head 59; the upper ends of said rollers at this time having been spread apart to receive the coins, by the engagement of the cam slots 36 with the upper journals 24 to 27 inclusive of said rollers, with the turnin of the cam disk 34 by the engagement of tie lever 79 with the disk arm 37 upon the swinging of said lever by the cam 72. When the slide barrels B are moved from under the stacking tubes d, p, n and q, the upper plates 12 of the slides 3 pass under the lower ends of said tubes and support the stacks of coins therein, until he slides return to normal position and heir barrels B again rest under the stack- 1 ng tubes, whereupon a predetermined numer of the lowermost coins in said tubes again drop into said barrels for the next sorting operation. Each time a slide 8 is moved forwardly and the stack of coins dropped from its barrel, the counting mechanism is operated by the link 16 and one stack is registered on the register B.

As soon as the coins drop into the wrapping mechanisms W the levers 79 are swung by'the cams 72 backwardly and the springs 38 turn the cam disks 34 clockwise; whereupon the cam grooves 36 engaging the upper journals 24 to 27 inclusive swing the upper ends of the rollers 10, 'w, 'w and 'w inwardlyagainst the coin stacktherebetween, while the lower ends of the rollers are drawn against the coin stack by the spring belt 64,

i coils (see Fig. 13) while the lower and upper edges of the wrapper are respectively crimped by the crimpers K and K a short distance over the lower face of the lowermost coin in the stack, and a short distance over the upper face of the uppermost coin in the stack, leaving a sufficient area of said faces of said coins exposed so that the denomination of the coins may be seen and read (see Figs. 6 and 14). The rollers w, w, 'w and w are then spread apart by the cam 72, through lever 7 9, cam disk arm 37,

disk 34 and cam slots 36, and journals 24:

to 27 inclusive. The plunger 58 is then elevated by the cam 73 through lever 80 and the wrapped stack of coins is elevated out of the wrapping mechanism W through throat 83 as shown in dotted lines in Fig. 6.
