Z '0 (1.72 whom it may (mice-rm.-

lie it known that l, ,lonx .lfl. Donor a citizen of the United States, residing at Portland, in the county of Cumberland and State of Maine, have invented certain new and usetul Improvements in lllachines for Operating upon Coins; and l do hereby'declare the following to be a full, clear. and exact description of the invention. such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to in ms for operating upon coins or other articles of disk tornn to separate them troin a mass and deliver them from the machine in succession.

The presentinvention is especially useful for separating; coins ot ditl'erent denominations from an iinliscriniinate mass and delivering them individually to devices where in they are subjected to further operations such as sorting and countin one object of the invention is to provide certain new and useful inuu-rwements in the construction and mode oil? operation of machines of the above character tor the pur pose of expediting: the separation of the coins and e'ltez'etinc their delivery flatwise in an orderly and substantially continuous procession.

Another objectof the invention is to ettect the separation of individual, coins or other articles, from a mass, by successive stages, each, of which consists of reducing thesize of the mass operated upon by separating therefrom a smaller portion.

A further object of the invention is to provide improved means for feeding the coins rapidly from a receiving hopper to a separating device and for insuring against the liability Of the coins becoming massed together in the hopper in such a manner as to interfere with the deliveryoit the coins therefrom.

With these objects in view, one feature of the invention consists in the provision of a hopper for receiving the mass of coins. a coin separating device and means for successively transferring limited quantities of the coins from the mass in the hopper to the separating; device.

Another feature of? the invention resides in the rotary distributing plate or disk and the cooperating" elements which comprise theseparating deviceand which effect the separation and individual delivery of the coins.

Still another feature or the invention con 1 prises the agitating device which serves to prevent blockading; or clogging of the coins in the hopper and to insure the master of a substantially equal quantity ot'coins from the hopper to the separating device at each operation of the transferring; means.

lo the 210C011!pllSlillflellt or these and such other objects as may hereinatter appear, the invention resides in the devices, combinations and arrangements ot parts hereinafter described and. subsequently defined in the appended claims and which possess 2ltlVt1l1- tages apparent to those skilled in the art. I

l The various teatures ot the invention will be readily understood troin the following description and the accompanying drawings illustrating the preferred the invention, in which A Figure 1 a view in front elevation of the machine showing also a sorting device to which the coins may be delivered; Fi m EZ a top plan view. partly in section on l ne f22 oi Fig. l shcwvinn' particularly the driving mechanism; Fin. is a view in vertical longitudinal section oi": the hopper and its supporting coluinn showing the agitating device and the transferring mechanism; Fig. 4: a detail view looltino at the top of the separating; device and showing also portion of the hopper: l 5 is a view in rear elevation. partly broken away. of the parts shown in Fig l; Fin. 6 is a top plan view of the hopper and the separating dcvicez Fi gz 7 is a detail sho ing a section on line T-'-7 ot 4:: 8 showing a section on line F?-8 and Fig. 9 is a p rspectiveview separaing; device. I

ln the pri [1 ed embod of the invention illustrated in the drawings, the machine comprises. in general. a hoppe 12., in which the mass of coins is deposited and which is support-ed by hollow COll -il'li'l is, rising from a base 16; a coin separating device 18. which supported b a post 20. projecting: upwardly from the base to. and is provided with a pocket or receptacle into which the coins are lelivered from the hopper and an inclined rotary distriou in."

ot Fig. 41; out the corn t k or separating; plate which forms one sid oi the pocket 22 and which operates to s parate the coins from the ma in the coin pocket and to cause them to be delivered successively from the deiuee; a coin chute embodiment of is a detail 26 for conveying; the coins from the hopper 12 to the coin pocket 22; a plunger 28. within the hollow column let, which is adapted to move upwardly through the hopper to raise a limited number of coins above the mass in the hopper and discharge them into the chute 26; means including the vertical rods 30, 32 and 34 which project through the walls of the hopper adjacent the plunger 28 and. are actuated by the movements of the plunger to agitate the coins in the hopper: and means for operating the plunger and for rotating; the distributing plate.

In the present machine, thus briefly described. substantially the same number of coins are delivered into the coin chute 26 and guided thereby to the separating device at each operation of the plunger. This intermittent transfer of coins from the hopper to the separating device occurs with sutficicnt frequency to maintain the proper quantity in the coin pocket 22. A great deal of difliculty has heretofore been experienced in coi'itrolling the feeding of coins or similar articles" from a hopper. in which a large quantity is contained; a satisfactory and uniform delivery being seriously lntertered. with by the tendency of the coins to mass themselves together in such a way as to check the flow. The herein described mode of feeding the coins from the hopper has proved to be an exceedingly effective way of overcoming the tendency of the coins to become blockaded and for insuring: the feeding; of the coins at a substantially uniform rate irrespective of the quantity in the hopper. The coin pocket oi the separating device in effect. a secondary hopper which is kept replenished from the main hopper so that just the proper working quantity of.

coins is maintained in the mass in. the pocket from wh ch the coins are seperated by the distributing plate. In the main hopper the cloggingor blockading ot' the coins prevented by the action of the agitating device. while in the coin pocket of the separating device the tendency of the coins to become blockaded is minimized because of the lesser number of coins confined therein and further by the construction and arra mentof the stationary rewaininp wall of the pocket and by the operation of the rotary distributing plate, all of which will be hereinafter described.

The hopper 12 which is supported by the column it is substantially tunnel-shaped. being formed by walls which flare outwardly and upwardly from one side of the hollow supporting column and merge with a semicylindrical vertical wall 36 which is an eX tension of the opposite side of the column. The coins are poured in at the open top of the hopper and are intermittently fed from the hopper into the chute 26 by the plui'iger 28 which is moved upwardly, through an opening in the bottom of the hopper, to tho levelot the top of the chute. The sloping walls of: the hopper cause the coins to settle toward the bottom. and as the mass diminishes, the coins will gradually slide toward the recess or pocket 38 which is formed above the plunger by the wall 36, so that there will always be a mass of coins directly over the plunger so long as any coins remain in the hopper. The plunger which is entirely retracted within the hollow column. when in its lowermost position. is partially housed by the semi-cylindrical wall 36. as the plunger moves up and down in the hopper. This wall 36 provides lateral support for the coins which are carried upward by the plunger and is 'lorn'ied at the top with an iiipcninp; it) to permit the passage oi the coins into the chute 26 when the plunger is at the top of its stroke. The top face of the plunger is inclined toward the chute sutficiently to cause the coins to slide oil the plunger and into the chute when the plunger reaches the top oi. its stroke. and the inclination ot the chute is such that the coins will slide down the chute by gravity and be deposited in the coin pocket of the separating device. Because of the inclination of the top face of the plunger toward the wall 36. the coins will tend to slide toward this retaining wall as they are elevated. rather than back into the mass in the hopper and consequently a greater number will be raised by the plunger than would 1 the ca e ll its top l :c was level. For the purpcse oi tacilitatingr the release into the chute oi" the coins which are raised by the plunder. the upper face of the plunger is provided with narrow parallel grooves 42. whch extend toward the chute and serve to reduce any tendency of toe coins to adhere to the top of the plunger due. tor example. to dampness or the pixsencc ot'i'oreig 'n substance on the faces of the coins l t necessary, in order to prevent hloclc ad ngr. or clogging of the coins in the hopper. and to insure that the flow oi coins from the mass in the hopper into the recess or pocket 38. as the plunger recedes. will not be interfered with. to provide suitable means tor agitating the coins at each operation of the danger To this end the vert cally disposed agitating rods 3!). 3i and 34. are arranged alongside ot' the column it with their upper ends projecting through the bottom of the hopper. As the plunger rises. th rods are pushed upwardly together tllIfOtlQl] the mass of coins and on the downward. movement of the 'ilun qer. the rods are withdrawn. Thus the for mation of the mass is distributed each time coins are "fed from, the hopper and the coins are not permitted to arrange themselves so as to prevent the settling' or flowingot the mass to fill up the cavity let't by the removal of the last group of coins by the plunger. The agitating rods are locatedclose to the column 14, the rods 30 and 32 being arranged on opposite sides thereof and adapted to rise in the hopper closely adjacent the corners formed by the j'un ction of the wall 36 with the walls of the main part of the hopper. wh le the rod 3 L is equidistant from the others and arranged. to operate in .a planeopposite the pocket 38.

The tops of all of the agitating rods normally project slightly above the bottom of the hopper. shown by dotted lines in Fig. l. The rods 30 and 32 which are rigidly connected by a cross bar 4:4 extend throuizh and are guided by bearings 4-6 on the column 1st. and are si'ipported by spring-s 48. whfch surround the rods below the cross bar and rest upon the upper end of the bearings -16. while the rod 3-iextends through a lug 50 formed on the cross bar and through a lug 52 lillO ltl'tllig from a block 54. which is secured tothe lower end of the plunger. and projectsthrousrh a slot in the column 14;. the rod being; supported by the engagement of the lug 50 on the cross bar with a. collar 58 which is fixed on the rod. On the upward movement of. the plunger. the lun 52 slides upward on the rod 34- and after thebloek 54- has come into contact with the cross bar 44 the three rods are raised in unison to points about midway hetweenthe bottom and the top of the hop ')er. 0n the downward inovemeiuzo the plunger the rods will ordinarily be held in their elevated positions by the pressure of the, mass of eoinsaeainst thein unt l the lung 52 on the blocl; 54 engages a head 60 wh ch is formed at the lower end. of. therod 34 when the three rods will be retracted to- ,rether from the hopper. The'springrs serve to cushion the downward movement of-.the agitating device and prevent undue noise and shock froin resulting therefrom. while a. spring 2 surrouni'l npr the rod 34 above the collar performs a similar function on the upward movement of the agitators. It will be observed that when the plunger is in liSPXtIGIDQ lower position the sprinir 48 will be compressed and the rods w'll be retracted slin'htlv more than shown in Fig; 1. thus permitting an unobstructed How of coins along the bottom of the hopper and over the top face of the plunger.

The separating device 18 to which the coins are led by the chute 2t; cin' prises the inclinedfrotarv distributing plate or dist; 24. and a stationary disk-shaped head 6-ion which the distributing plate supported and which .is providei'l with a. peripheral coin retaining wall '66 which partly surrounds the head. A peculiarly shape-l curved wall 68 which is an extension of the wall 66 serves, inconjunction withthe piste itself, to form the pocket 22 (Fig. 8) into which the coins are del vered from chute 26. while the peripheral wall {56 prevents the escape of the coins laterally. from the separating devi e as they are being rotated with the distribiufiine plate until they are ready to be finally delivered from the machine. The angle of inoliinltion of the distributing; plate ill egreater than the angle of normal rep se of he coins by an amount suli'icient to inst 3. the sliding of the coins by gravity toward the lower part of the plate. The dist bf," ball liearii' and is secure-1. to

The reniainin portion of the i ibuting plate is sup 'iorted Etfllretl llv located on the upper surbv virtue of the attacht portually come into contact wall 68 diminishes in height as it extends toward the margin. of the head 64- where it merges with the peripheral wall 66. For the purpose of preventing the escape of the coins between the end of the walltiS, adjacent to the block 82 and the discharge chute 26. the cylindrical face of the block 82- is extended upwardly at this point by means of the wall 88 as shown in Fl 5 and 9. I

In order to effect the separation of the coins from the mass in the coin pocket. ,2.

the upper surface of the distributing: plate is provided with a plurality of radiating feed strips or ribs 90' which serve to distribute the coins from the surface of the distrilnrting' plate. lhese feed strips project above the surfaceof the plate an amount equal, to or slightly less than the thickness of the thinnest coin to be operated upon, which is the (nine. and they extend outwardly from the cylindrical surface of the block being inclined in the direction of rotation of the plate and falling some what short of reaching the periphery thereof. [is the plate rotated in a counter clockwise direction, viewed from. above, a limited number of coins are engaged by each feed strip as it passes beneath the mass in the pocket, and are elevated thereby. lying Hat on the surface of the distributing plate, and being" prevented from sliding to the center of the plate and back into the coin pocket by thehlock 82. the cylindrical sides of which mnstitute an ahutnrnt which will engage the innermost coin on each feed strip. It will he ohseiwed that it will be impossible for more than a single layer of coins to he thus separated from the mass by the action of the feed strips shine the top face of the thinnest of the coins will be flush with or slightly higherthan the upper surfate of the ted strips, sov thatas the strip passes under the mass in the pocket a coin lying above another already engaged by the strip cannot itself be cngaged thereby. the coins which are being carried by the feed strips reach their highest posi tion on the distributing plate, gravity causes them to slide down the inclined surface of the plate to the left of the block 92 in Figs. at and 9. is they slide downwardly some of the coins will str the feed. strip preceding the one by which they were elevated. and will be diverted thereby toward the periphery of the plate. All of the coins even ""ith the coin re taining wall 66, along which they slide until they reach an extension 92 of the inclined marginal edge of the head til, across which they are delivered successively from the separating device. T he speed of rotation of the distributing plate such to cause delivery of ti o coins from the separating device in a substantially continuous procession. As shown in the drawings, the coins may be delivered to the prrn'i'ary' chute 9st of. a sortina' device such as that shown at of the head (34 and the upper surface of the plate 24 are covered by a plate 98 which is secured to the wall (36 on the left hand side of the separating device. as shown clearly in l igrs. 4. and 9. A cover 100 of wire mesh may he provided as shown in Fi :1 to inclose the top of the coin pocket. .22 and prevent possible overflowing of the coins.

.lt-is necessary to guard against the sibility of any coins, which may for any reason adhere to the surface ofthe distributing plate, becoming jammed between the edge of a teed strip and the outside of the wall fitl'of the coin pocket 62, and thus clogging the niechanisn'i. To this end the distril'iuting plate is provided with a series of shallow grooves 102 concentric with the periphery of the plate, and into each groove projeits a small pointed prong 104. The ron;;'s 101 extend from a plate 106 which is se'ured to the wall-U68 of the coin pocket and have the function of dislodging the adherent coins and causing them to'slide down the inclined face of the plate 24 and properly join the procession of othercoins. The wall 68 is cut away on its under side adjacent to the surface of the plate 24, where it overlies the feed strips, sufliciently to permit the feed strip to pass thereunder. Vv'hile none of the thicker coins are able to pass through the opening thus provided. for the entrance of the feed strip into the coin pocket, the dimes, and more especially such of them as have been worn to less than normal thickness. may possibly do so. The prong re -i. however. also performs the func tion of preventing the escape from the coin pocket of any dimes which may be thin enough to pass through this opening.

The mechanism may be operated from any Suitable source of power. As shown an electric motor 108 drives the main shaft 110 continuously through a worm 112 on the motor shaft, which engages a worm wheel 11st on the main shaft. A bevel pinion 116 on the main shaft meshes with a bevel gear 118 on a shaft 120 to drive the latter shaft. T his shaft 1:20. in turn. drives the vertical shaft 80, by means of which the distributing plate Q-l rotated, through .intermeshing bevel gears 122' and 124 on the shafts 120 and 80 respectively. In addition to driving, the ver tical shaft 80 the shaft 120 also drives a crank shaft 126 through a pinion 128 on the shaft 120, which meshes with a spur gear 130 on the crank shaft. 'A crank arm 132 on posthe crank shaftis operatively connected through a crank pin 13% and. a link 136 with a lever 1.38 which is iulcrumed at l lo. The connertion is made at a point 1&2 between the fulcrum 14M) and the opposite end of the lever 138 which projects through a vertical slot 14-14 in the supporting: column 14; andis pivotally connected at l-LlG with. the lower end of a link M8, the upper end 0t which is pivotally connected at 150 with the base oi? the plunger Rotation oi the crank shaft 126 causes oscillation in a *ve'ticai plane of the lever 138 which in turn cau rcciproczu tion of the plunger 28. In order to provide means for conveniently connecting ann disconnecting the mechanism from the main drive shaft, the bevel pinion 116 is mounted upon a sliding hub 152 which is splined to the main shaft, and an actuating rod 154 is connected with the huh through an arm 156 and extends to a position conveniently arcessible tothe operator where it is provided with ahandle 158, in order that it may be manipulated to control the movements of the gear 116.

Aiter the coins have been delivered by the present machine to a sorting; device. such a. that indicated generally at 96 in Fig. 1 and have been sorted and distributed to separate points, it may be desirableto count them. For this purpose suitable counting; mechanism. not shown in the drawings, may he associated with the sorting; device and ar'- ranged to be driven by the main shaft of the present machine. The means herein pro-- vided for connecting and disconnecting the mechanism of theppresent machine with the main'shat't is of especial utility when countingmechanism is also operated by the main shaft, since it permits the operation of the former mechanism to be controlled without interfering with the operation of the countingmechanism. It is contemplated that the counting mechanism may be advantageously mounted upon the table which is shown in Fig. 1 as supporting; the sorting; device' lVith .this in mind, the handle of the actu' ating rod has been so locatedthat the opera tor will be, able to manipulate it while at the same. time watching" the operation of the sorting and counting of the coins.

ll hile it is preferred to employ the specific constructionand arrangement of parts herein shown and described, will be understood that this construction is not essential except so liar as specified in the claims and may be modified without departing: {T0111 the broader features of the invention.
