No. 87,398 6 Claims. (6l. 19d- 102) This invention relates to coin operated mechanism and especially to a coin receiving unit having means for separating good coins from spurious ones and without jamming of the unit that would require operator attention before the coin operated mechanism could be caused to operate through another cycle.

Coin operated vending machines have become inereasingly popular in recent years with the number of units as Well as the types of merchandise dispensed, increasing at a rapid rate. Most of these vending machines are operated by the customer either depositing coins of preselected value in the machine, or in the alternative, inserting certain coins followed by manual operation of selector buttons, levers or similar vend mechanisms. Because of the fact that the vending machines are many times located in unattended areas and furthermore because of the fact that constant surveillance is not maintained over the machines, attempts have been made to obtain products from the machines without deposit of genuine coins. Counterfeit coins, slugs, metallic discs and other similar objects have been used in efforts to actuate the vend mechanism and for this reason, complex and highly refined coin selecting apparatus has been develope-:l over a period of years, for separating spurious coins from genuine coins regardless of the type of counterfeit coin which is deposited in the vending machine. The coin selecting units have conventionally employed various means for testing the authenticity of the coin as to size, weight and materials from which the objects are made, but some diiculty has heretofore been experienced with respect to detecting slugs or discs of slightly smaller than proper diameter and which have physical properties very similar to that of agenuine coin.

Most coin selecting apparatus utilize cradle structure pivotally mounted substantially in the zone of juncture of a coin rejecting pathway therebeneath, and a coin accepting pathway adjacent the coin rejecting pathway, and with the cradle being provided with spaced projections thereon adapted to support a coin of a particular denomination so that the cradle is pivoted about the axis of rotation thereof to divert the coin into the coin accepting pathway. The spaced projections on the cradle structure, however, are sufficiently spaced to pass therethrough coins of other denominations which have smaller diameters. The coins passing between the cradle projections are directed into the coin rejecting pathway. Thus the cradle principle is suitable for separating coins or discs having relatively wide diameter differences such as nickels, dimes and quarters, but such cradle is not capable of being utilized to separate coins or discs of slightly smaller than required diameter, from coins of predetermined, particular diameter. The spacing between the cradle projections has not proved satisfactory as a means for rejecting slugs or discs of a slightly smaller diameter than a proper coin for the reason that the slightly smaller coin would have a tendency to become wedged between the cradle projections and could not be cleared from the mechanism upon operation of the scavenger. Consequently, the cradle projections are purposely designed to be spaced very appreciably closer than the minimum diameter of the particular denomination of coin to be normally supported therebetween. It is basic that the center of gravity of a coin carried by the cradle projections is to one side of the axis of rotation of the cradle so that the latter will be rotated in a manner to divert the coin on the projections, into the coin accepting pathway.

it is therefore the most important object of the present invention to provide coin selecting apparatus as described including novel means for preventing rotation of a cradle as dened .above when the same issupporting a coin of slightly smaller than proper diameter whereby the coin will be ejected from the coin receiving mechanism upon manual actuation by the customer of the reject lever. in this respect, it is to be pointed out that a further important object of the invention is to provide coin selecting apparatus as referred to above wherein the means for preventing rotation of the cradle when the latter is supporting a coin of slightly smaller than proper diameter, cooperates with and engages the cradle to preclude rotation thereof to divert such coin into the coin accepting pathway.

A still further important object of the invention is to provide coin selecting apparatus wherein the means for preventing rotation of the cradle unless the latter is supporting a coin of predetermined diameter, includes a swingable lever having means thereon projecting into the coin receiving pathway and which is engaged by the coin while the latter is carried by the cradle projections, so that during swinging of the cradle under the weight of the coin deposited thereon, such coin shifts the projection on the adjacent check lever to move the latter into disposition clearing the cradle whereby `the latter may divert the genuine coin into the coin accepting pathway.

Other important objects including the simplicity of the present check lever and the effectiveness thereof without jamming of the machine, will become obvious or be explained in greater detail as the following specification progresses.

The coin selecting apparatus broadly designated 10 in the drawings includes a main frame 12 having a normally vertically disposed, rectangular Wall 14 provided with a pair of integral, outwardly extending, opposed, vertical side walls i6 and 18 projecting outwardly from the normally front face of wall 14. A pair of integral ears 2t? and 22 projecting inwardly from Wall 18, receive an elongated pin 24 which mounts a main gate 26 and a secondary gate 2d which rare rotatable 'about the vertical axis of pin 24. The gate 26 includes a generally rectangular plate portion 3) having a mounting extension 32 on the end thereof proximal to wall 1S as well as a pair of outwardly projecting, integral legs 34 and 36 which are positioned adjacent the outer opposed faces of respective ears 20 'and 22 and rotatably receiving pin 24 so that gate 26 may swing' toward and aw'ay frdrn the proximal face of wall 14. The coil spring Se surrounding pin 24 between ears 2G and 22, has a pair of opposed coiled portions 38a and 38h, and an integral, outwardly projecting, central portion 38C disposed to engage the inner face of wall 18. rlhe outer rectilinear extremity 33a' of 'coil spring and projecting outwardly from portion 3817 thereof, engages a cross portion 40 integral with opposed legs 41 and 43 of secondary gate 26, while the extremity 38e of spring 3S and integral with portion 38a of the latter, engages the outer face of rectangular portion 30 of gate 26 to force the latter toward wall 1d. As best shown in FIG. l, legs 41 and t3 of gate 28 are located between

ears

20 and 22 and are pivotal about pin 24. The main section 42 of gate 2S carries a transversely L-shaped coin clearing member 44 provided with an inwardly extending outer leg portion d6 which projects away from secondary gate 28 and thereby toward wall 14. The plate portion 30 of main gate 26 is provided with an elongated slot 48 therein for clearing leg portion 46 of member 44. The rectangular boss portion 50 of gate 23 and integral with main section 42 thereof, houses a pair of permanent magnets 52 which test the coins for magnetic properties and thereby trap all objects deposited in apparatus which are suciently attracted by magnets S2 to be held thereby.

A pair of

pins

54 and 56 secured to the plate portion 30 of gate 26 adjacent the upper left-hand corner thereof viewing FIG. l are located in horizontally spaced relationship to present a coin receiving opening of predetermined width therebetween, it being pointed out that pins 54 and S6 extend toward and releasably engage the inner face of Wall 14 to thereby maintain gate 26 in predetermined spaced relationship to wall 14.

Pins

54 and 56 are preferably positioned to pass a coin of required diameter therebetween, but at a distance insufficient to pass a larger coin such as a half dollar for example, if selector apparatus 10 is designed for operation by quarters. The upper margin of plate portion 30 of gate 26 adjacent side wall 16 is flared outwardly at 58 to cause coins deposited in apparatus 1t) to be directed downwardly through the space between

pins

54 and 56.

A coin testing cradle broadly designated 60 is pivotally mounted on plate portion 30 immediately below pins 5d and 56 as shown in FIG. 1, with cradle 60 inciuding a main, generally circular portion 62 provided with a pair of

opposed legs

64 and 66 at approximately right angles with respect to each other. Inwardly extending projections 68 and 70 are integral with

corresponding legs

64 and 66, with plate portion 30 of gate 26 having a pair of opposed upper and lower

arcuate slots

72 and 74 receiving projections 68 and 70 respectively. The central circular portion 62 of cradle 6G has a tubular boss 76 thereon which extends outwardly from cradle 60 and thereby provides means for mounting the latter on a pin '7S carried by plate portion 30 of gate 26 and extending forwardly therefrom. A Ceclip 80 on the outer extremity of pin '78 extending through central portion 62 of cradle 60 as well as tubular boss portion 76 thereof, releasably maintains cradle 60 on gate 26 but permits free rotation thereof in an arcuate path of travel limited by the length of opposed

arcuate slots

72 and 74 receiving projections 68 and 70 respectively. The central portion 62 of cradle 60 also has a pair of arcuate margins 82 and 84 normally facing toward member 44 and interrupted by a shoulder 86 provided with a surface in generally radial relationship to the axis of pin 7S. A counterweight S3 on the outer face of central portion 62 of cradle 60 is eccentric with respect to the axis of pin 73 and thereby biases cradle 6G in a counterclockwise direction viewing FIG. 1

L2. whereby projections 68 and 70 are normally in proximity to the ends 9i) and 92 respectively of

slots

72 and 74.

in addition to the novel conguration of cradle 60 and particularly the margins 32 and 84 thereof in conjunction with shoulder 36, the additional unique element of the present invention is the undersize coin check lever or member 94 which is mounted on plate portion 30 of gate 26 in proximal relationship to cradle 60. The central portion 96 of member 94 is provided with an integral tubular boss $9 on the rear face thereof which pivotally receives a pin 9B carried by and extending outwardly from plate portion 30 of gate 26. The outwardly projecting extension 100 integral with central portion 96 serves to bias member 94 in a counterclockwise direction as shown in FIG. 1, whereby the inwardly extending pro jection 162 of central portion 96 of member 94 is normally maintained in proximal relationship to margin 84 of cradle 69 in a position causing shoulder 86 to normally engage projection 102 of member 94 as cradle 60 is rotated in a clockwise direction. Upwardly extending, generally L-shaped leg 164 integral with the upper margin of central portion 96 of member 94, has an inwardly extending projection 106 thereon with plate portion 3i) of gate 26 being provided with an elongated slot 198 therein for clearing projection 106 to permit check member 41 to pivot about the axis of pin 9S. It is to be noted that a C-clip 116 on the outer extremity of pin 98 and engaging the outer surface of central section 96 maintains boss 99 against the outer face of plate portion 3Q.

Main plate portion 30 of gate 26 is provided with a trapezoidal shaped component 112 thereon adjacent the lower margin 114 of the same and having an upwardly facing, inclined surface 116 presenting a coin runway and cooperating with the inner surface of plate portion 30 and the proximal surface of wall 14 to present a coin accepting pathway in proximal relationship to the inagnets 52 carried by secondary gate 28.

in order to permit coins to be cleared from the cradle 61B if the same are oversize or undersize, a manually operable lever 113 is pivotally mounted on the rear face of wall 14 opposed to

gates

26 and 28 and is provided with an integral, inclined cam surface 120 thereon which receives a projection 122 integral with the inner face of plate portion 30 of gate 26 whereby during downward movement of lever 118, the projection 122 slides along inclined surface 120 to thereby force gate 26 outwardly against the action of coil spring 38. A leaf spring 124 carried by the pivot pin for lever 118 and engaging the upper, outwardly projecting portion of the latter as well as an outwardly projecting nut 126 on wall 14, normally biases lever 11S into the uppermost position thereof whereby gate 26 is in proximal disposition with respect to the inner face of wall 14.

During swinging movement of gate 26 with respect to frame 12, secondary gate 2S does not move therewith, because of boss 12S on main section 42 of gate 2S which extends through an opening 130 in plate portion 30 of gate 26 and thereby engages the inner face of wall 14, as best shown in PEG. 3.

In operation, apparatus 1t) is positioned within coin controlled mechanism forming a part of a vending machine or the like, and thus the coin receiving opening in the upper part of frame 12 defined by ared portion 58 of gate 26 as well as the proximal portion of wall 14 and opposed

pins

54 and 56, is disposed to face upwardly in direct alignment with a coin entrance chute. As the coin 132 gravitates between

pins

54 and 56 and thereby into the coin receiving pathway, such coin initially engages projection 6i; on cradle 60 and is thereby directed toward the projection 70 on leg 66 of cradle 60. Assuming that coin 132 is of proper dimensions for the particular coin selecting apparatus 10, the coin will be supported by both of the projections 68 and 70 in bridging relationship thereto in a location substantially as shown in FIG. l. Inasmuch as the center of gravity of coin 132 is to the right of the axis of shaft 78, viewing FIG. l, cradle 60 is rotated in a clockwise direction against the influence of counterweight S3 whereby the coin 132 is diverted toward the coin accepting pathway presented by the inner face of wall 14, the opposed faces

af gates

26 and 28 and the upwardly facing surface 116 of runway component 112.

As soon as cradle 60 has rotated through a relatively short arc, the outer margin of the coin engages the projection 106 on member 94 as shown in FIG. 5, thereby causing member 94 to swing in a clockwise direction and moving projection 106 on central portion 96 of member 94 away from margin 84 of cradle 60. The coin 132 shifts leg 104 and thereby member 94 through a suicient arc to cause projection 1% to clear shoulder 86 of circular portion 62 of cradle 6G (FIG. 6) whereby the cradle may rotate through a suihcient arc to direct the coin 132 onto the runway surface 116 of component 112. After coin 132 has left the cradle 60, the latter is returned to the initial position thereof under the action of countervveight 88 and the extension 10i) of member 9d returns the latter to the location illustrated in FIG. 1.

In the case of an undersize coin, even though the same is cradled between projections 68 and '79, the cradle 60 is not permitted to move through a sufficient arc to divert the coin onto runway 112, because of the fact that the coin will not engage projection 106 in a manner to shift member 94 through an arc to cause projection 196 to clear shoulder 86 on central circular portion 62 of cradle 6l).

The check member 94 also prevents cradle 60 from being rotated by an undersize coin of insufficient diameter to be cradled on projections 68 and 7d and which in certain instances, could otherwise occur. For example, if apparatus 1d is designed for selecting quarters and a dime is dropped into the coin receiving passage, such coin could drop downwardly with suihcient force to engage the projection 7i) of cradle 6l? and thereby rotate the latter through an arc to throw the dime into the coin accepting pathway presented by runway component 112. Because a coin of this diameter will not engage the projection 196 on check member 94, the latter will not be permitted to rotate through an arc to clear shoulder 86 and thus preventing rotation of the cradle 6).

As previously noted, it is to be understood that an undersize coin carried by cradle 60 will be rejected from apparatus 1i) upon manual actuation of lever 118 by virtue of the fact that gate 26 moves outwardly to cause the projections dS and '7G to release the coin inasmuch as the leg portion 46 of member 44 contacts the proximal surface of the coin and prevents the latter from moving along with projections 68 and 70 during outward movement of cradle 6@ on plate portion 3% of gate 26. By virtue of the fact that the undersize coin has not passed through the coin receiving pathway presented by component 112, such undersize coin will be directed to the reject passage of apparatus 10.
