1"' One modification of theinvention, as illus- Atratedin Figs. 1"to 6, has todo with a coin selecting'devic'e' which may be referred to as a 4 in 1,

such as toaccept four denominations of coins, as

'for'fexample pennies,nickles, dimes and quarters. In this modification there is provided a Ageneral downwardly sloping coin receiving chute which at the same time is curved laterally so that as the cins'roll down the chute they are thrown to i one side and thereby caused to be thrown through 'selected openings in a partition wall of the chute, dependingupon the size of the coin, substantially in the manner shown and describedin theabovementioned 'Letters Patent to Adrian.

Thus'the coins of the four denominations receivediin this device are 'entered through a single .coin entranceulll YAdjacent the entrance TI the .curved side wall of the chute is provided with a :window Il of such sizeA to `permit coins or slugs of lessl diameter than a dime to pass therethrough -intofari'ejecting chute "9 through which they pass from the selector. In the curved partition wall immediately following the window 8 there is pro vided-'a window Il] of Asuch size as to permit passagetherethrough of pennies and dimes, but too small to receive nickels and quarters. VThe pennies and dimes are thrown through the window -IUiby centrifugal force so as to fall into a lower passageway II having a window I2 in the outer curved wall thereof just large enough to 'permit a dime to fall therethroughwhile directing the penny tothe discharge end of the lower passageway.r The said curved partition wall immediately following the window` I0 divides the upper portionvof the chute into a primary upper passageway and an auxiliary upper passageway, said partition wall beingprovided with a window I3 immediately' Vfollowing the "window I0 therein through which the nickels are directed to the auxiliary passageway for discharge from the end of the chute, whereas the quarters continue past 'the window I3 for discharge adjacent, and to one side of the nickels. i' p Thusdu'e to the lateraly curvature of the'chute Emea/iev the smaller slugs are immediately thrown thereby said force through the window IU of the pri-` mary up-per passageway to drop down into the lower passageway. In the lower passageway the dimes are thrown through the window I2 to one side of the chute, while the pennies pass said window for discharge from the end of the lower passageway on the other side of the chute. The nickels and quarters pass the window I0, but the nickels are thrown by centrifugal force through the window I3 in the partition wall separating the primary upper passageway of thechute from an auxiliary upper passageway. rIhus separated, the nickels and quarters roll to the far end of the upper passageways to be discharged therefrom, the quarters on one side of the chute and the nickels on the other side.

Substantially centrally of the chute and depending therefrom therev is a center partition plate i4 so arranged relative to the chute that the 'penniesand I dimesare discharged into `pas'- sages "on`opposite sides of said plate substantially centrally thereof, and the nickels and quarters are Vdischarged from `said chute to passageways on opposite sides of said `partition plate adjacent the far edge thereof. .This is by reason of the fact that the lower passageway through which thefpennies 'and dimes pass terminates short of the .upper passagewa'ys.vv

` `F'romthe above Vit will be understood that slugs of le'ss'diameter than a dime have already been discharged 'before separation of the coins, as above described( 'lso, in the mannerhereinafter referred to, those coins of paramagnetic material will have been eliminated and discharged.- As above set forth, the remaining coins have been separated as torsiZe. It now remains for each of the separated coins to be again separated as to 'weightand magnetic character of the material. YIn this manner theremaining slugs or unacceptable coins are separated from' the acceptable coins.' For this purpose there is mounted on each side of the center partition plate I 4 a hinged swinging gate, the gate I5 being hingedly mounted on one side therof and the lgate I6 on the other side thereof." The nickels'and dimes, as above described, are directed to pass between the partition `plate I4 and the swinging gateII, whereas the pennies and quarters are directed to pass `between the center'partition plate I4 and the swinging gate I5. Each of said gates has mounted `thereon the principal coin sorting elements which will now be traced in respect to each size of coin. i" The quarter4 sized coin inserted in the coin slot 1, being of greater 'diameter than the height ofthe units 8, Ill' and I3, rolls on its edge past them tofall between the partition plate and the gate "I5 into a passageway indicated at I1. The penny drops between the partition plate I4 and gate I5 into a passagewayindicated at I8. The nickelpassesbetween the opposite sideof the partition plate and gate I6 into a passageway vgenerally indicated Yat I9, whereas the dime passes between the partition I4 and gate I6 into 'the passageway indicated at 2U. As each coin drops down in its passageway andv'provided'that it is of proper weight, it falls upon an inwardlyand downwardly sloping runway. The quarters `fall onto runway 2|, the pennies onto runway 22, the nickels onto runway 23fand the'dimes onto runway 24. Said runways comprise narrow strips of metal Vformed coins.`

arteria:

'ensecured to the inner wall: cti their respective 'gates-to extend adjacent `to but; free from the partition plate I4;

However, if such coins are" below standard weight; allowance for wear being taken` into, ac-

count; they are caught between the center par titiorr` plate |54 and a restraining `finger mounted Vupon ai counterbai'ancel lever. Thus in the pas.- -sagfe I'r through which the quarter passes and in line .with its-runway li, there is provided' arestraining finger slopin'gdow-nwardly at` an angle-1 parallel to the runway 2:! andxmounted .swung to open. `position as..lclereaite'r described.

- V1li/iouin'ted" upon the gate |55 t'o lie` within- 'an opening so as. to face the inner surface thereof, there is provided"` a magnet 2,8 past which a coin of. proper weight is caused' to roll down the` run'- wayZLlf. The'purpose of. the magnet 281is' toxeffectthe velocity or speedv of travel of the rolling 'coin as it passes through the magnetic field.

the speed or velocity of the coin is varied according tothe magnetic characteriet'i'cs,ofA its composition'. Forwardly of the path of travel of a coin of proper compositionthere` is a swinging anvillil' pivotally mounted at 30 to swing downwardly adjacent' the inner face of the gate; The

position Vof said anvil may be adjusted withrefspect! to the path; of travel. of they coin by an Aadjustin-g screw 31 extending through an arcuate yslot 32'A for clamping it to the gate in. adjusted position.

By means of this arrangement, if thetcoinis of proper composition it will pass tl'irouglfl4 the 'magnetic eld ofthe magnet 281m a trajectory shorter the anvil 29 so that it will not strike it. It `the" composition of the coinis such that the ieldz` will have little or no effect thereon, `its rollingspee'd will carry it into: contact with the anvill, whereupon it will bounce to the left. If, on the other hand, should the magnetic viield so afe'ctithe coinas to restrain its Velocity to a greater extent than a coin of proper composition, its trajectory will fall short and to the lett ofthe trajectory of a coin. of proper composition.

To control the disposition of the falling coins Iaccording to their respective trajectories=,'there isgprovided a diverter 33 arranged to divert the `coins dropping through the proper trajectoryto theri'ght for entry into the slot for acceptable Those coins which bounce off of theanvil 29 4oriall short will be directed by the diverter to the left into a reject chute.

- The `diverter comprisesa plate 34 adjustably mounted on the gate l5 by a screw 35 adjustably clamping the gate through a slot` 36. Pivotally `mounted yon said plate at 3T there is 'a beam 38 normally resting upon the screw 35 and having at one' end thereof a ccunterbalance `weight 39. At/the other end of the beam there` is a pendulum 40 with a bob All,` said pendulumv carrying a lugY 4t2 extending through an 'opening' in theA gatetransversely of the passageway between said gate and the partition plate I4. The lug 42may be positioned by the screw 35 to extendat the `critical point` in the trajectories ofthe coins. .Thilstthe rst sligsl rebounding .from `the anviltot either clearllu'g'. 42;- onfalltupon: it: with. their center: 5f-gravity: substantially to.` theleft. so as to drop;` into; the: reject passage indicated. aty4c3'. However;` the:- correct trajectory for: an, acceptable china of. suclfr c'onipo'sitinn as to bei` properlyV con;- trolled `byfther magnetic', held.` clears: the'A anvilJ 29 and drops to. the. right of lug 42. or engages:` said lu'gwith it`s= centen` of grayitywto the right so.,as to-drop intdthe coin acceptance chute"V indicated atc'll'l.`

As the trajectories-of ther-center. offgravity` of anceptable anormal-acceptable coins lie. veryr close togetiiez",I more accurate sorting isaccomplished by the diyerter'33' thanl is possible by otherzknown devices. leverp'endulum arrangement ot `the diverter has. the effect .ofV preventing the rebound of the coins which would occur if the diverter was unyi'el'ding. When a coin falls upon the. lug 4f2`wwith' its center ctzfgravityto the left; it `impels the" pendulum 40-to` thel right. abouttits` pivotal mounting upon the beam 38 by virtue of its horiaantal; component et? motion: due to. thel relative positiorisof its center of gravity andi the pointon its edge in- Contact Vwith said lug. Conversely,

z when the coin impinges uporil'ug 42with its cen.-

terjof gravity to the `right thereof, said lug is impelledf to the left. `By this. means said lug isincreasingly reinovedduring' the periortof contact trom a position beneath the center of gravity from the vertical plane the!"ethrough;` thereby increasinglthe moment` ofthe couple which tendsto 4'throwy the coin. one direction or the other. Si-

multaneously the `lug Wdescend's as the impact oi the coin. depressies the pendulum and raisesathe counterweightf. This has alcushioning eiectby reason` of the yielding to the impacti increasing the time the' @ein is in contact4 with the lue and thereby increasing' the distancel it may swing horizontally and hence increasing the moment of the coupleabov'ementioned'.

y Aipartition` Adama-y be formedwon the innerrsur'- l face of the gate` to eri-close the space in `which the quarter siizeel'coins are caused to be separated. The coirisfotY other sizes andideriominations are similarly acted upon to separate the acceptable coins" iront those thatare unacceptable. On the same side of the partition plate the pennypasses between said plate and the gate -l`l5. Thev penny entering the coinr slot 1 is thrown through the lll-by the' curvature of the wall to drop down into the lower passageway Il androll to the end thereof past the windowA I2" through which the dime dropson the other side of the par: ti-tion. The penny then falls through the. passage indicated at I8 and if"of` insunicien-t' weight it is restricted by a finger 46; Otherwise itolls down the runway 2'2 through the magnetic held` createdby a magnet 41'. Ii it is ofboth theproper weight and of the proper material, it will` be so affected 'by` the magnetic field as to drop in a trajectoryto the left of and free from engagement with an anvil 48LV The anvilv 48 is readily adjusted through the screw and slot 49 so asl toextend inwardly from th'einner wall of the gate in' adjusted relation to the.V proper trajectory of the "gatel', The lug. 50 ismounted on a pendwlumf pivotally'suspendedfrom` oneend ofa beam 55, f'whichfbeamV is fulcrumed upon the plate 53 and lisprovidedwith a counterweight 56. .,Itwill be -noted that the pendulum.v 54 does not have a Weighted bob at'the lower end thereof, as in the diverter 33,"and themasses are vmore restricted.

As'aboveidescribed, if `.the coin is not sufficiently retarded by the magnetic field it ystrikes theanvl v'fi'and rebounds to the left of the lug;50. Cn the other hand, if it is excessively retarded its center of gravity fallsto'the leftof the lug 50.` In either event-j such coin is inacceptable and passes through the passage indicated at 51 into the slug `rejecting chute. On the other hand, if the conis of proper` composition, the magnetic field through which it passes vwill so affect its trajectory as to `causeit to clear the anvil and fall to the right 'of the lug 50,01' engage said lug with its center of gravity to the right. l yThereupon it will drop .into the passage indicated at `58 as an acceptable com.

Dimes willdrop through the window I2 from a ,lower passageway II, as above described, and `therebybe directed to the other side of the partition plate I4 to drop between said plate and the opposed gate I6. They will then pass through the passage indicated at 20, engaging a weight control finger 59 similar Sin all respects to lingers 25 and 46. If the dime is of suilicient Weight to `pass th'enger, it rolls down the runway 24 past the magnetic lield induced'by a magnet 6U which magnetically controls the path of-its trajectory. If it is not sufciently restrained by the eld, it strikesan anvil 6I which is in all respects the same as the-anvil 48 above described, and bounces to the right'of a lug 62 on a diverter generally indicated at' 63. `Said diverter 63 is in al1 material respects the-same as the diverter 5I above described. The coin will thereupon drop to the right of a separating stud 64 through a passageway for unacceptable coins generally indicated at 65. Similarly, a coin which is excessively slowed down `by the magnetic field will drop short of the anvil 6I, but with its center of-gravity to the right of the. lug 62 and through the passage 65. However, if the dirneis of proper material the effect of the `magnetic eldwill be such that its trajectory will carry its center of gravity to the left of lug 62 so thatrit will pass the stud 6,4 to the left and drop -into the .passage for acceptable dimes generally indicated at 66. i i Nickels, having passed through window I3, ywill be guided to the "space between the partition plate vI4 and the gate. I6, carrying to the eX- treme endofthechute to pass through the passage generally indicated at I9 onto the runway 23. In doing so, the nickel must pass the weight control nger 61. If it is of sufficient weight to Ipass thelinger 61 itvwill roll through the magnetic` field ofthe magnet 68. The trajectory of fthe vacceptable coin,\as aiected bygits passage 'through the magnetic eld, will cause it to im- Vpingeupon an anvil 69 secured to and extending inwardly from the gate I6 with its surface at a. substantially 455degree angle. A nickel of proper alloy -will bounce from the anvil 69 over a diverter l1li4 anddrop to the rightv of said diverter to fall through the passage generally infdicated atU'II. *Unacceptable coins which are so affected bythe magnetic eld as to have less momentum fail to strike the anvil 69 with energy yenough' to be thrown beyond the diverter 1l), and are `either repelled by it or fall through to -the left, or mayfail entirely tol strike the an- ;vil and,-,therfore, fall between said. anvil andthe 8 diverter'.` In any event, suchunacceptablelcoins are caused to fall-to the left of the diverterifor rejection through the passage generally indicated 2.1712. l 1 i I As shown in Figs. 3, 4 and 5, near the coin opening] there is a plate 13 or" paramagnetic material secured tothe coin chute bythelugs 15. The wall of the chute adjacent said plate is cut away,` and contiguous theretothere isa plate 14 of similar material. To-this second plate 14 thereis attached a magnet 16 which is pivotally mounted by a hinge pin 11 in lugs 18 corresponding to lugs 19 on the plate 13. One of the lugs 18 extends laterally to provide an arm 80. This arm, when depressedfcauses the plate 14 with its magnet 16 to. swing outwardly about the hinge pin 11 away from the plate 13. The magnetic iield of the magnet 16 is suflicient to traverse the space intervening between the plate'13 and the coin chute. Consequently a coin oiv paramagnetic material entering the chute is attracted through the cut away portion of the inner wall thereof, and if heavy enough it drops between said wall and plate 13 outside of the chute to be discharged. On the other hand, iff the coin of such material is not heavy enough to drop away, it is held magnetically on the inner face of the plate 13 until the magnet 16 is swung away therefrom by depressingthe arm 80. The coin will 'thereupon be released to drop downwardly from outside of the chute for discharge. To swing the magnet 16 away from the chute for the above purpose, the-arm is depressed by the downward longitudinal movement-M13 vrod 8|. Said rod is provided witha hook ,portion 82 engaging and bearing upon the upper .edge of the arm 80. Said rod is mounted `to slide in the guides 83. lIt is kept from revolving `in its guides by having its down turned upper end inserted in an adjacent guide 84 beside the guide 83.

Extending through said rod 8| (Fig. l) there is Iafpin 85 which bears upon one end' of a. bell ,crank 86 which is pivoted at 81 upon partition plate I4. The opposite end of the bell crank 86 consists of two spaced parallel camming arms188 extending astride the plate I4 to swing between said plate and the camming rollers 89 rotatably mounted` inthe respective gates I5, I6. Upon the rod 8| being depressed the pin'15will swing the bell crank 86 to cause its camming'arms to engage their respective rollers 89 to swing therespective gates laterally away from the partition plate.

Said gates are hingedly mounted upon opposite sides of the kpartition plate by a hinge pin i90 and are held close against the partition plate under tension of the springs 9|. The rod 8I, 'together with the bell crank lever 86, is returned to normal position `under tension of a compression spring 92. n

"The rod BI is arranged to be manually delvpressed, inA event of a coin being deposited and neitheraccepted for operating the machine or returned. When' the rod is thus depressed the magnet 16 is swung away to permit any coin adhering to the plate 1:3 to drop and be discharged. The same action through the bell crank 88 swings 'both gates I5, I6 away from the partition plate I4, carrying with them the lingers 25, 46, 59 and 61. Therefore, any light coins which are wedged under the ngers are freed and are thrust by 'said lingers laterally to drop past the respec- .tive runways 2|, 22, 24 and 2i3, said runways beiing mounted uponthe swinging gate. This per- .mits in, jlight coinj wedged tag-ainsi', the partition selector.

In the .modified -fonn of the invention shown A@in =Figs. -7 :to 1-7 the coin :selecting `device is defsigned to handle five coins, Aire., a penny, nickel, lrdime; quarter and ftyucent piece. Basically the :same principle and many of the rsame'iparts-are .femployedinzthis modiflcationlas in the'one -pre- -viously described for rhandling four coins, Yand ,ltoithat end Ina-ny'of parts of this modified form are:designatedby ,the same numbers as the 4related part of the foregoing -modiiication butJ Ain-the `100 series.

The unacceptable coins passing .with the quartersthrough zpassage li 9 similarly rebound `from `the the pivotal mounting 221. If of suflicient weight to pass the finger, they roll down the runway 22| past the magnet 228 to drop to the left of the lug |50 carried by the diverter I5I which is similar in all respects to the diverter I of Fig. 1. They arek confined by an auxiliary chute |52 by which they are guided for discharge. The unacceptable coins passing down the chute |06 will strike the anvil 229 and bounce or freely drop through the magnetic eld with the center of gravity to the right of the lug |50 for discharge on that side of said auxiliary chute |52.

Similarly to the modications of Figs. 1 to 6, this modification is provided with a Amagnet |16 mounted adjacent the opening of the chute. It is supported upon the swinging plate |13 pivoted at 11 to swing up and down along the side of the coin chute. The plate |13 swings upward adjacent the scraping flange |14 formed on a curved hood |15 As the plate swings upwardly afslug of paramagnetic material, which may be stuck to the wall thereof by the magnet, will be scraped therefrom bythe movement past the scraping edge |14. Said scraping edge of the hood |15 extends over an opening |18 in the forward wall of the chute through which such slug will dropout of the device. The magnet |16 is weak by comparison with the magnets located on either side of the runways, as previously described. The purpose of the latter magnets is to provide a strong magnetic eld which sets up eddy currents in the passing coins. However, the purpose of the magnet |16 is lto divert iron and steel slugs. Its weakness prevents too frequent an operation of the scavenging mechanism, for in a great majority of cases it draws iron slugs out of the chutefar enough to fall f-reely through the opening |18 but not far enough to reach the magnet and cling to it.

The scavenging operation is shown in Fig. 9. A shoulder screw |19 is secured against turning `in the partition plate I4 by a shoulder nut |80 and the lock nut IBI. A sleeve |82 revolves on the screw |19 and has secured to its end a lever |83. An arm |84 is free to oscillate on the neck of the shoulder nut |80. A spacer |85 and associated rivets connect the arm |84 and a similar arm '|86 above the upper edge of the partition plate I4 so that the two arms oscillate in unison inthe space between the partition plate and the gates ||5, II6. The arm |86 is provided with a lug `|81 which extends across the path of the lever |83. When the lever is depressed it swings arms |86 and |84 by means of said lug. Each of the gates I I5, I I6 is provided witha roller |89 which engages the partition plate at a point within the path of movement of the swinging'arms |84, |86. WhenV said arms areA forced between' said rollers andthe partition plateby the lever I 83, the gates will be forced away from said plate.

The opposite end of the lever |83 is slotted at |88'4 to receive an actuating pin so that upon movement of the arm |83 the magnet |16 will -be swung upwardly to cause a stuck coin to be scraped therefrom. A spring |98 serves to return the arms |84, |86 back to'normal inoperative position.

A bracket 9 I is riveted to a iiange of the plate I 4*v having perforated lugs for receiving a rod |92 through which it slides vertically.y Said rod is provided with a slide |93 'attached `thereto by a set screw-|94, Saidslide is'provided with a pair of parallel lugs fwhich are traversed by 'a horizontal stud |96 which enters 'aslot inthe lever I 83. Said slide near its lower end has a pair` of parallel lugs |91 whose curved ends are incontact with the upper end of the bracket l9land serve to keep the slide parallel thereto to prevent rod |92 from turning. A spring |98 surrounding `'said rod bea-rs downwardly on the lower lug of bracket' I9| and upward on the lower lugV ofthe slide I 93,'returning the latter and the rodto upper position after having been depressed. VKThe downward movement of the rod' causes thestud operating the y `|96 to depress the lever |83, thereby scavenging mechanism. l

As noted in Fig. 8, to scavengeV the penny'seL lector there is provided an a-rm 200 which is`p`iv `oted at 28| to the inner wall of the gate IIB. It `isformed with a cam 202 (Fig.T 10) in Contact with said gate. When the gate -I I6 is swung away from the partition' plate, it'presses the cam 202 beforeit, swinging* the tip 293 through` aistill longer arc to remove the penny selector'vfar enough from said gate to allow anything caught by the 'scale linger 225 to fall'free.'v As shown in Fig. '1;' thereY is an eXtra runway |2211 beneath the nickel runway |22. '1It is'ati tached to` the partition plate I4; extending'toward the gate ||5 andV serves to Iprevent =a scavenged slug from entering the nickel exit directly below. It will be noted'from the above thatv i'nrei spect to this second modification, wherein 'five coins are handled up to and including -a Aiifty cent piece, the principle of operation `is substantially the same as the rst described'modication, particularly in respect to the various paths of travel of the coins with the control levers therein. However,l to make room for the iifth coin, an auxiliary channel is provided for the penny intermediate the channels of the dimes and` quarters (Fig. 8), and `which involves a somewhat different arrangement of structure, vboth* in the coin receiving chute and the slug scavenging mechanisms' It is to be understood that the term coin is herein used in its broadest sense to not only apply to legally minted money, but to those metal pieces simulating minted money and generally referred to as slugs. Thus by the term unaccepted coin as herein employed, is meant that metal piece sometimes referred to as a s1ug, and acceptable coin that which is legally minted. Y

The invention claimed is: A

1. A coin selecting device including a coin receiving chute, a selector providing a confined space for receiving coins of predetermined size from said chute, a sloping runway in saidvspace for causing said coins to roll downwardly thereon and drop therefrom, means for producing a magnetic` field through which said coins are directed by said runwayto vary their velocity and trajectory upon leaving said runway depending upon the magnetic composition thereof; a yielding diverter 'adjustably supported on said selectorbelow said runway generally in the pathof said coins to divert` those coins 'dropping onv said diverter to one side or the other thereof, depending upon the relative positions of the center of gravity of said coins when .striking said diverter, said diverter comprising a lever pivotally mounted intermediate its endshaving a counterbalance weight on one end thereof and a pivoted pendulum on its opposite end with a depending bob, and an intermediate lug on Vsaid pendulum.`
