MONEY HANDLING DEVICE Filed April 25, 1967 United States Patent 3,411,613 MONEY-HANDLING DEVICE Gordon C. Andreas, St. Louis, Mo., assignor to National Rejectors, Inc., St. Louis, Mo., a corporation of Missouri Filed Apr. 25, 1967, Ser. No. 633,628 Claims. (Cl. 194-97) ABSTRACT OF THE DISCLOSURE A coin-handling device has a flipper that alternately directs coins of the same denomination into a first chute and into a second chute; and that flipper is equipped with a counterweight which can move with that flipper but which also can move relative to that flipper, and which can keep blows that are applied to that coin-handling device from causing that flipper to shift into position to di rect coins into that second chute.

This invention relates to improvements in moneyhandling devices. More particularly, this invention relates to improvements in coin-handling devices which requires a plurality of coins of the same denomination to actuate them.

It is, therefore, an object of the present invention to provide an improved coin-handling device which requires a plurality of coins of the same denomination to actuate it.

A coin-handling device, which requires a plurality of coins of the same denomination to actuate it, can have a flipper mounted adjacent a coin passageway therein; and that flipper will normally be positioned so a coin moving along that coin passageway will be intercepted by that flipper and be directed into a first chute. That coin will be guided by that first chute toward a cash box or toward an escrow device in advance of that cash box. As that coin is directed into that first chute, it causes that flipper to shift into a position where that flipper will direct a second coin, moving along that coin passageway, into a second chute. That second coin will be guided by that second chute to an electrical or mechanical actuator which will provide the desired actuation of the coin-handling device. As that second coin is directed into the second chute, it will cause that flipper to shift back into its normal position. Where a flipper-equipped coin-handling device is permitted to operate in the manner in which it is intended to operate, it can require two coins of the same denomination to be inserted before it is actuated. Unfortunately, however, it has been discovered that when sharp blows are applied to certain ortions of the exteriors of vending or other machines in which some flipper-equipped coin-handling devices are mounted, the flippers of those devices can be caused to shift from their normal positions to the positions wherein they will causethe nextsucceeding coins passing through the coin passageways of those devices to pass to the second chutes thereof rather than to the first chutes of those devices. Any such shifting would be very objectionable; because it would enable a patron to obtain the desired product or service from that vending or other machine by the insertion of just one coin rather than the intended two coins. It would be desirable to provide a flipper for a coin-handling device which could perform the functions of directing a first coin into the first chute and of directing a second coin into the second chute, and which could not be shifted from its normal position to its flipped position by the application of blows to the exterior of the vending or other machine in which that coin-handling device was mounted. The present invention provides such a flipper; and it is, therefore, an

3,411,613 Patented Nov. 19, 1968 object of the present invention to provide a flipper for a coin-handling device which can perform the functions of directing a first coin into the first chute and of directing a second coin into the second chute, and which cannot be shifted from its normal position to its flipped position by the application of blows to the exterior of the vending or other machine in which that coin-handling device is mounted.

Other and further objects and advantages of the present invention should become apparent from an examination of the drawing and accompanying description.

In the drawing and accompanying description a preferred embodiment of the present invention is shown and described but it is to be understood that the drawing and accompanying description are for the purpose of illustration only and do not limit the invention and that the invention will be defined by the appended claims.

FIG. 6 is an exploded view, on the scale of FIG. 2, of the flipper incorporated in the coin-handling device shown in FIG. 1.

Referring to the drawing in detail, the numeral 20 denotes a wall of a coin-handling device which requires a plurality of coins of the same denomination to actuate it; and that coin-handling device can be one of a number of coin-handling devices which are presently being marketed. One such coin-handling device is the nickel-dimequarter coin-handling device made by National Rejectors, Inc. of St. Louis, Missouri. An arcuate guiding surface 22 extends forwardly from that wall; and that arcuate guiding surface has a downwardly-directed portion, a concave portion, a horizontally-directed portion, and a second downwardly-directed portion. A horizontally-directed guiding surface 24 extends forwardly from the wall 20 at a point above the horizontally-directed portion of the arcuate guiding surface 22; and that horizontally-directed guiding surface will coact with that arcuate guiding surface to guide nickels toward the trailing edge of the horizontally-directed portion of that arcuate guiding surface. The horizontally-directed guiding surface 24 has an inclined face 26, at the top thereof, which extends through the wall 20, as shown by FIG. 2; and that inclined face is intended to guide dimes through an opening in that wall. A boss 28 extends forwardly from the wall 20 adjacent the left-hand edge of that wall; and that boss and the second downwardly-directed portion of the arcuate guiding surface 22 define a space which is disposed forwardly of that wall. The wall 20 has an arcuate surface 30 extending downwardly below the bottom edge thereof, as shown particularly by FIGS. 1, 2 and 4; and that arcuate surface has a vertically-depending flange 32 adjacent the rear edge thereof. A pivot 34 extends forwardly from the forward face of the wall 20, and that pivot is located approximately mid-way between the boss 28 and the second downwardly-directed portion of the arcuate guiding surface 22.

The-numeral 36 generally denotes a flipper; and that flipper has an opening 38 therein which telescopes over the pivot 34 and which confines that flipper for rotation about that pivot. As shown particularly by FIGS. 3, and 6, the flipper 36 has a convex-concavo rib 40 at one end thereof, has a concave-convexo rib 42 adjacent an elongated edge thereof, has a short rib 44 adjacent that elongated edge, and has a surface 46 adjacent the opposite end thereof. The rib 42 has a thickened free. end, as shown particularly by FIGS. 5 and 6. The ribs 40, 42 and 44 and the surface 46 coact to define a shallow recess 48 in the rear face of the flipper 36. The ends of the ribs 42 and 44 confront each other but are spaced apart a short distance adjacent the opening 38 in the flipper 36. The flipper 36 also has an elongated, generally-straight edge 47; and a concave surface 49 is provided at that end of that edge which is close to the surface 46. The free end of the rib 40 is spaced from the surface 46 by a distance which is close to, but not as long as, the overall length of the flipper 36. A pin-like protuberance 50 extends rearwardly from the flipper 36 adjacent the said opposite end of that flipper. That protuberance underlies the lower edge of the wall 20; and it can engage that lower edge of that wall, in either of the positions of that flipper, to act as a stop.

The numeral 52 generally denotes a counterweight for the flipper 36; and that counterweight has an opening 54 which can telescope over the pivot 34 that is supported by, and that extends forwardly from, the wall 20. The counterweight 52 has a concave edge 56 which has a configuration that is generally complementary to the convex face of the concave-convexo rib 42 on the rear of the flipper 36. That counterweight also has a convex end 58 which is generally complementary to the concave face of the convex-concavo rib 40 on the rear of that flipper. That counterweight is dimensioned to fit loosely within the recess 48 defined by the ribs 40, 42 and 44 and by the surface 46 at the rear face of that flipper. An ear 60 on the counterweight 5 2 extends toward, but terminates short of, the surface 46 on the flipper 36; and that ear is dimensioned so it can engage, and be held by, the short rib 44 on that flipper, as shown particularly by FIG. 3.

The numeral 62 denotes a second wall of the coinhandling device; and that wall is disposed immediately adjacent the forward edge of the arcuate guiding surface 22, is disposed immediately adjacent the forward edge of the horizontally-directed guiding surface 24, and is disposed immediately adjacent the front edge of the boss 28. That wall will coact with the wall 20, the arcuate guiding surface 22, and the horizonatally-directed guiding surface 24 to define a passageway 64 through which coins can move toward the flipper 36. The pivot 34 and the second downwardly-directed portion of the arcuate guiding surface 22 coact to define a first chute 66; and that chute is arranged to receive coins which are not intended to actuate the coin-handling device. The pivot 34 and the boss 28 coact to define a second chute 68; and that chute is arranged to receive coins which are intended to actuate the coin-handling device. The chute 66 will direct coins to a cash box or to an escrow mechanism in advance of that cash box; and the chute 68 will direct coins to an electrical or mechanical actuator for the coinhandling device, and then to the cash box.

The opening 38 in the flipper 36 is large enough to enable that flipper to rotate freely about the pivot 34. Similarly, the opening 54 in the counterweight 52 is large enough to enable that counterweight to rotate freely about that pivot. As a result, coins that are introduced into the passageway 64 and that are guided into engagement with the flipper 36 by the guiding surfaces 22 and 24 can easily rotate that flipper and that counterweight about that pivot. v

The normal position of the flipper 36 is shown by FIGS. 13; and, in that position, the pin-like protuberance 50 underlies and engages the lower edge of the wall 20 to hold the concave-convexo rib 42 in position to intercept any coins that pass beyond the trailing edge of the horizontally-directed portion of the arcuate guiding surface 22. That concave convexo rib coacts with the short rib 44 to define a pocket which is presented to any coin which passes beyond that trailing edge of that horizontally-directed portion of that arcuate guiding surface; and that pocket is intended to hold any such coins.

Whenever the flipper 36 is in its normal position, the ear 60 on the counterweight 52 will engage and be held by the short rib 44. The center of mass of the flipper 36 will be above and to the left of the pivot 34 in FIG. 1; and, because that center of mass will be disposed to the left of that pivot, that center of mass will bias that flipper for rotation in the counterclockwise direction in FIG. 1 The center of mass of the counterweight 52 will be disposed to the left of the pivot 34 in FIG. 1; and that center of mass will be disposed further to the left of that pivot in FIG. 1 than will the center of mass of the flipper 36. Furthermore, whenever that flipper is in its normal position, the center of mass of that counterweight will be considerably lower than the center of mass of that flipper. As a result, the counterclockwise bias on the counterweight 52 will add to the counterclockwise bias on the flpper 36. Also, and importantly, that counterweight will dispose the composite center of mass of itself and of that flipper appreciably below the level of the center of mass of that flipper.

When a coin moves through the passageway 64 and passes beyond the trailing edge of the horizontally-directed portion of the arcuate guiding surface 22, that coin will engage the concave faces of the ribs 42 and 44 of the flipper 36; and that coin will be intercepted and held by the pocket defined by those ribs. The center of mass of that coin will be disposed to the right of the pivot 34 in FIG. 1, and hence that coin will cause the flipper 36 to rotate in the clockwise direction in FIG. 1. That flipper will rotate from its normal position in FIGS. 1-3 to its flipped position in FIGS. 4 and 5; and, as that flipper so rotates, the coin will enter and move downwardly through the chute 66. That coin will pass to the cash box, not shown, of the coin-handling device or to an escrow mechanism in advance of that cash box. The gravitational forces on the flipper 36 and the counterweight 52 will resist the force applied to that flipper by the coin until after the center of mass of that flipper passes to the right of a vertical line passing through the pivot 34 and until the center of mass of that counterweight passes to the right of that line. Thereafter, that flipper and that counterweight will urge that flipper to move into, and to remain in, the flipped position shown by FIGS. 4 and 5.

In that flipped position, the pin-like protuberance 50 on the flipper 36 will underlie and engage the lower edge of the Wall 20, and will coact with that lower edge to hold the generally-straight, elongated edge 47 of that flipper generally horizontal. Also, the concave edge 56 of the counterweight 52 'will abut and be held by the thickened free end of the rib 42, as shown particularly by FIG. 5. At such time, the counterweight 52 will be disposed within the recess 48, as shown by FIG. 5; and that is desirable because it will keep that countenweight from obstructing the movement of any further coins moving through the passageway 64. Also, at such time, the straight edge of the counterweight 52 will be substantially flush with the generally-straight edge 47 of the flipper 36, as shown by FIG. 5; and this means that a second coin which moves through the passageway 64 and passes beyond the trailing edge of the horizontally-directed portion of the arcuate guiding surface 22 will roll onto, and be supported by, the straight portions of the flipper 36 and of the counterweight 52. That coin will roll past the pivot 34, and then 7 will engage and be intercepted by the concave portion 49 of that flipper. That coin will apply a downwardlydirected force to the concave portion 49; and that force will tend to rotate that flipper in the counterclockwise direction in FIG. 4. The weight of that coin will be great enough to rotate the flipper 36 and the counterweight *52 from the positions shown by FIG. 4 to the positions shown by FIG. 1; and as that flipper so rotates it will guide that second coin into the second chute 68. That chute will guide that second coin toward a switch, a lever, or the like, not shown; and that coin will engage that switch, lever, or the like to actuate the coin-handling device.

The flipper 36 and the counterweight 52 will resist the rotation thereof from the flipped positions shown in FIG. 4 to the normal positions shown in FIG. 1, until after the center of mass of that flipper has moved to the left of a vertical line through the pivot 34 and until the center of mass of that counterweight has moved to the left of that line. Thereafter, that flipper and that counterweight will tend to urge that flipper into the position shown by FIG. 1. After the flipper 36 has reached the posiltion shown by FIG. 1, and further counterclockwise rotation of that flipper is prevented by the engagement of the pinlike protuberance 50 with the lower edge of the wall 20, the counterweight 52 will continue to rotate in the counterclockwise direction until the ear 60 on that counterweight again engages and is held by the short rib 44 on that flipper. At such time, the flipper 36 and the counterweight 52 will again be in the positions shown by FIG. 1; and that counterweight will again be applying an important and substantial biasing force to that flipper, which will tend to hold that flipper in that position. That biasing force is important; because it will keep persons, who apply heavy blows to the exterior of the vending or other machine in which the coin-handling device is mounted, from causing the flipper 36 to shift from its normal position over to its flipped position.

When the flipper .36 is in its flipped position, the counterweight 52 is wholly disposed within the recess 48 in the rear face of that flipper and the straight edge of that counterweight is flush with the generally-straight edge 47 of that flipper, as shown by FIG. 5. As a result, whenever that flipper is in its flipped position, the counterweight 52 can help that flipper perform its coin-supporting function. When the flipper 36 is in its normal position, the counterweight 52 extends down part way out of the recess 48 in the rear face of that flipper, and thereby shifts the composite center of mass of itself and of that o flipper and counterweight downwardly.

Absent the counterweight 52, the center of mass of the flipper 36 is displaced far enough above the level of the pivot 34 and is spaced such a short distance to the left of that pivot that appropriately-applied blows of sufficient magnitude can cause that flipper to shift from its normal position to its flipped position. However, the center of mass of the counterweight 52 is so much lower than that of the flipper 3 6 and is spaced so far to the left of the pivot 34 that the composite center of mass of that counterweight and flipper is considerably lower, and is considerably farther to the left of the pivot 34, than the center of mass of that flipper. The overall result is that the counter-weighted flipper 36 strongly resists all efforts to shift the flipper from its normal position to its flipped position by the application of heavy blows to the coinhandling device or to any vending or other machine in which that coin-handling device is used. Consequently, that counterweighted flipper can perform its functions of directing a first coin into the first chute 66 and of directing a second coin into the second chute 68, and yet can strongly resist all improper efforts to cause it to shift from its normal position to its flipped position.

Whereas the drawing and accompanying description have shown and described a preferred embodiment of the present invention, it should be apparent to those skilled in the art that various changes may be made in the form of the invention without affecting the scope thereof.

a counterweight that is movably attached to and thus is movable with, but also is movable relative to, said fl pp said counterweight acting whenever said flipper is in said initial position to assume a biasing position relative to said flipper wherein it biases said flipper to remain in said initial position and wherein it locates the composite center of mass of itself and of said flipper below the level of the center of mass of said fl pp whereby said flipper will tend to remain in said initial position despite the application of heavy blows to said coin-handling device,

said counterweight acting whenever said flipper is in said flipped position to assume a dilferent biasing position relative to said flipper wherein it biases said flipper to remain in said flipped position,

said counterweight responding to gravity to move relative to said flipper and to move into said different biasing position as said flipper moves from said initial position to said flipped position and also responding to gravity to move relative to said flipper and to move into the first said biasing position as said flipper moves from said flipped position to said initial position,

interacting surfaces on said flipper and on a stationary part of said coin-handling device which limit the movement of said flipper as said flipper moves back to said initial position, and

further interacting surfaces on said flipper and on said counterweight which limit the movement of said counterweight as said flipper moves back to said initial position,

said further interacting surfaces permitting movement of said counterweight relative to said flipper after the first said interacting surfaces limit the movement of said flipper as said flipper moves back to said initial position,

the first said interacting surfaces being a protuberance on said flipper and an edge of a wall of said coinhandling device,

said further interacting surfaces being an ear on said counterweight and a rib on said flipper.

9. In a coin-handling device wherein a flipper is movably disposed in a passageway and has a coin-supporting surface thereon which is intended to receive a first acceptable coin whenever said flipper is in an initial position and direct that first acceptable coin toward a first chute and to move to a flipped position as it does so, and has a different coin-supporting surface thereon that is intended to receive a second acceptable coin when said flipper is in said flipped position and direct that second acceptable coin to a second chute and to move back to its initial position as it does so, the improvement which comprises:

a counterweight that is movably attached to and thus is movable with, but also is movable relative to, said flipper,

said counterweight acting whenever said flipper is in said initial position to assume a biasing position relative to said flipper wherein it biases said flipper to re main in said initial position and wherein it locates the composite center of mass of itself and of said flipper below the level of the center of mass of said flipper,

whereby said flipper will tend to remain in said initial position despite the application of heavy blows to said coin-handling device,

said counterweight acting whenever said flipper is in said flipped position to assume a different biasing position relative to said flipper wherein it biases said flipper to remain in said flipped position,

said counterweight responding to gravity to move relative to said flipper and to move into said different biasing position as said flipper moves from said initial position to said flipped positon and also respending to gravity to move relative to said flipper and to move into the first said biasing position as said flipper moves from said flipped position to said initial position,

said counterweight having a coin-supporting surface thereon, and

said coin-supporting surface on said counterweight and the first said coin-supporting surface on said flipper being adjacent each other and coacting to support the same coin whenever said flipper is in said initial position.

10. In a coin-handling device wherein a flipper is movably disposed in a passageway and has a coin-supporting surface thereon which is intended to receive a first acceptable coin whenever said flipper is in an initial position and direct that first acceptable coin toward a first chute and to move to a flipped position as it does so, and has a different coin-supporting surface thereon that is intended to receive a second acceptable coin when said flipper is in said flipped position and direct that second acceptable coin to a second chute and to move back to its initial position as it does so, the improvement which comprises:

a counterweight that is movably attached to and thus is movable with, but also is movable relative to, said flipper,

said counterweight acting whenever said flipper is in said initial position to assume a biasing position relative to said flipper wherein it biases said flipper to remain in said initial position and wherein it locates the composite center of mass of itself and of said flipper below the level of the center of mass of said flipper,

whereby said flipper will tend to remain in said initial position despite the application of heavy blows to said coin-handling device,

said counterweight acting whenever said flipper is in said flipped position to assume a different biasing position relative to said flipper wherein it biases said flipper to remain in said flipped position,

said counterweight responding to gravity to move relative to said flipper and to move into said different biasing position as said flipper moves from said initial position to said flipped position and also respending to gravity to move relative to said flipper and to move into the first said biasing position as said flipper moves from said flipped position to said initial position,

said flipper having a recess therein, and

said counterweight extending into said recess to avoid obstructing further coins Whenever said flipper is in said initial position.
