UNITED STATES PATENT OFFICE COIN SELECTOR George 8. Brodd, Chicago, 111.
Application March 28,
The present invention relates to coin receiving devices for-machines of various sorts, and has a particular relation to such a device for a vending and change-making machine.
Particular objects of the coin receiver are the selection of genuine coins from non-genuine coins; the sounding of an alarm or signal in the event false coins are inserted; the exhibiting of false coins; the immediate rejection of magnetic metal slugs; the immediate separation of genuine and non-genuine inserts; and the crediting of accepted genuine coins to an account.
One object of the invention is the provision of selective electric switches operated-by an insert as a selector, according to its diameter.
Another object of the invention is the use of the coin itself to bridge electrical contacts, and the selection of the contacts by the denomination, or physical characteristics of the coin or insert.
Another object of the invention is the prevention of breaking at the coin of the electrical connection established by the coin, whereby there can be no sparking at the coin to result in injury thereto, or to the contacts employed.
Various other and ancillary objects and advantages of the invention will appear from the description and explanation of the invention which will be hereinafter given in reference to an exemplary embodiment thereof shown in the accompanying drawings and described in detail explanation of i parts and functions.
The inventio here described and claimed does not include th entire merchandising machine above referred to, but only a part thereof. The invention is not limited to the specific use hereinafter described, and it is to be. understood that it may be used as described, or altered for other purposes. Because the invention itself is illustrated by a specific embodiment and is described in combination with parts which are useful in such a machine, it is not to be construed as a limitation of the invention short of its scope as expressed in the appended claims.
The device shown in the accompanying drawings includes a magnetic selector for preventing magnetic slugs from entering parts adapted for the receipt of genuine coins. It is operative automatically to reject the magnetic slug and to condition itself for immediate receipt of a genuine coin. It is preferably placed immediately within the coin receiving slot. The magnetic ejector will pass non-magnetic coins or false coins into another selector which receives the coin in a generally tapered space adapted to re- 1932, Serial No. 601,478
ceive the coins edgewise between the tapering sides. The taper may be gradual but is preferably stepped so that coins of different denominations have a definite resting place. In that place each coin, when genuine, has its correct 5 diameter such that it bridges two fixed electrical contacts. When it falls into correct place and bridges the said contacts it operates a specific relay, which causes the coin immediately to be ejected in a direction predetermined to receive genuine coins. The specific relay also operates electrical mechanism to cause registration and crediting of the genuine coin. The relay also energizes itself to continue its function after the coin is removed from the contacts initially bridged by the coin. Other mechanism functions to deenergize the relay after the crediting operations are initiated.
In the event a non-genuine coin or slug is used it is quite usual that such coins are larger or go smaller in diameter than the minted coins for which the operating crediting contacts are spaced. On each side of the position predetermined for genuine coins, there may be other contacts which will be bridged by either larger 5 or smaller slugs, or even imperfect or damaged genuine coins. Such contacts operate the ejecting mechanism in a direction predetermined to! receive such bad inserts, and may incidentally give an alarm or signal, and cause the bad inserts to be exhibited, or returned.
The operations above described may readily be accomplished by simple structures as shown in the illustrated device. In the drawings:
Fig. 1 is a front view of the device.
Fig. 2 is a side view of the device taken from the right hand side of Fig. 1, illustrating an electromagnet on each face of the device.
Fig. 3 is a view similar to Fig. 1, with a part of the facial devices removed.
Fig. 4 is a cross-sectional view on the line 4-4 of Fig. 1, showing in detail the coin finger.
Fig. 5 is a diagrammatic view of certain parts of the device and an electrical diagram, the parts being operably associated for the preferred use of the device.
Fig. 6 is a modified form of bank of switches which may be selectively operated by a coin or insert.
The device comprises a plate III which may serve as a partition for chambers which are to receive good coins and bad inserts. There is an opening II in the plate in which lies a swinging coin-finger l2, preferably pivoted on pin it. The location of the axis is such that the side of the plate, as shown in the two lateral positions l2 and I2? of Fig. 4. The plate [8 the coin may .lie edgewise.
has parallel cars 14 and I5 projecting on the front side for the pin I3, and the finger I2 has two ears I8 and I1 for said pivotal pin l3. Resilient means is provided to cause the coin-finger l2 to remain normally in its opening in the plate I8, and to return thereto after being forced to either side position. Suitable means for doing this comprises a pin l8 on the finger projecting upwardly between the ends of two parallel leaf springs 19' and 28 which are mounted at their other ends on a bracket 2| on the plate It.
The finger I2 is comprised of two plates 23 and 24 with a coin-holding space between them to receive a coin by edgewise entry. In Fig. 3 the front plate 23 of the finger is removed exposing the inner side of finger plate 24. Coins are received by'edgewise entry at the top right end (Figs. 1 and 3) of the finger f'roma runway therefor, and on entering the finger strike .the curved baflie web 25 which deflects the coin downwardly into the finger.
n the faces of the finger are armature plates 26 and 21 (Figs. 3 and 4) which serve to swing the finger according to which of the electromagnets 28 and 29 is energized. Each of the electromagnets comprises two solenoids with cores, mounted on a bracket 38 secured to the top of plate In. The bracket" has a forwardly and downwardly projecting arm 3| carrying electro-magnet 28, and a rearwardly and back--' wardly projecting arm 32 carrying electromagnet 29. Thus the electromagnets are positioned at angles to correspond with the lateral positions of the finger l2.
By reason of the construction described th coin space in the finger between finger plates 23 and 24 lies forward of the partition and base plate l8. Suitable means are located laterally of said coin space to retain coins therein. Such means preferably form a tapered space in which Such means are utilized as electrical contacts to be bridged by the coin. A plurality of circuits,'and hence of contacts, is provided for successful selective operation of the device. On one side there is a 'metal plate 35, separated from the face plate II by an insulating sheet 36, and also covered by a second insulating sheet 31 (Fig, 1). The
edge is tapered, preferably in stepped arrangement as indicated by the steps'38. The depth and extent of the steps is determined by the coins for which the machine is designed.
' 0n the opposite side of the finger there are a line of contacts 39, preferably not stepped, but insulated one from the other, by insulation 40, and alined at the end to form a straight edge against which a coin maymove when it drops in the finger. A coin or slug thus may drop in the finger until it is obstructed at some point by the tapered space between said contacts 39 and contact plate 35. At the resting point the coin completes a circuit and causes the finger to be moved by one or the other of electromagnets 28 and 29. Certain of the contacts which are spaced for genuine coins cause the finger to move to one side for such coins, and others of the contacts cause the finger to move to the other side for coins or slugs refused by the machine. It is pointed out that when the finger I2 is moved laterallyfrom normal position there are no means to retain a coin or $1118 in the finger, and it slides out endwlse of the finger to either side of the partition ll.
A magnetic selector is employed to discard magnetic slugs before they enter the coin finger. It is preferably associated with the coin chute leading to the coin finger, and may form a part thereof. An illustrative structure comprises a coin chute of which one face is parallel to plate l8, on which isa sloping nmway 58 (Fig. 1) formed as a flange on a non-magnetic plate secured to face plate ll. At this region the plate III is preferably non-magnetic. The plate 5-! leads a coin C sliding or rolling against it, directly to the space in the coin finger. A
. swingin plate 52, 'onyertical axis 53, is held by a light spring 54 so. that it normally closes and defines the coin chute.
The structure may best be understood by reference to Figs. 1, 2 and 5. A permanent magnet 55 is located in front of the swinging plate 52 and spaced therefrom so that when a magnetic slug enters the chute it is drawn by the magnet and swings the plate forward. The
coin adheres to the plate 52 by the force of the .magnet. A spring contact 56 meets a fixed contact 51 and closes electrical circuit comprising wire 58 connected to the plate 52 and spring contact 56, battery 59, wire 58, which is connected to an electromagnet 8|, and wire 5P, connecting' the electromagnet to fixed contact 51. Electromagnet 5| is positioned to draw an armature 52, pivoted at 83, which may be the line of axis 53 (as shown in Pig. 1). The armature 62 carries the permanent magnet 55, so that as the armature is drawn forward upon swinging of plate 52, the permanent magnet 55 is so far removed from the coin, that the force is insufficient to cause the slug to adhere to the plate. The coin then drops in front of plate In. It may there be returned or exhibited, as by lying on a surface 54 behind a window 55. As soon as the coin drops, the plate 52 swings back. to define the chute, the electric circuit is broken, and a spring- 65 on the pivotal axis 53 causes the permanent magnet 55 to return to normal position for arepetition of the operation. If desired an alarm bell or other signal 51 may be placed in the circuit to function whenever an attempt is made to insertmagnetic coins.
In using the coin selector, auxiliary devices are employed which may be related to a crediting ma hine as above referred to. A part of the st cture of such a machine is referred to in connection with the remainder of this description, having reference particularly toFig. 5.
In Fig. 5 certain parts of the structure previously described are shown diagrammatically, and are similarly designated by .the numerals first applied. They are as follows: coin finger l2, contact plate 35, contacts 39, electromagnet 28 and electromagnet 29. It is to be'noted that bad coins or slugs are preferably thrown to the front for exhibition, along with magnetic slugs. Consequently electromagnet 28 operates for rejections, and electromagnet 29 operates for accepted coins. Legends in the drawings (Fig. 5) indicate the function. The contacts 39 are also marked with denominations of U. S. coins which each is designed to register. Contacts indicated S refer to slugs or rejections.
Each contact 39 is connected to a relay, and all the S contacts are connected in common to a single relay. The wire 18 is connected to each slug contact S and to the first relay ll of the series. Contact plate 35 is connected by a resistance element 12 to a power line 13 which contains switch 14. As shown, it is connected to live wire 60 of battery 59. The other terminal of the battery is connected by wire 15 which extends as a live wire past all the relays ter minating at both the electromagnets 28 and 29. The relay circuit is established as follows: Battery 59, wire 60, switch 14 (normally closed),
wire 13, resistance 12, plate 35, slug. contact" S", wire'l0, relay ll, a wire 10 from relay to wire 15, wire 15, battery 59.
When the relay is energized, an armature is employed to continue energization of the relay after the coin is removed, and also to energize electromagnet 28 for ejecting the slug. An armature is shown at 18, connected by wire 19 to power line 13. Contact 80 and wire 8| connect the armature electrically to wire 10, thus to continue energization of the relay. Contact 82 and wire 83 connect the armature to rejecting electromagnet 28, thus energizing the latter. Contact 84 and wire 85 connect the armature to wire 86 which leads to a relay 8! operable to open switch 14 in the power line 13, by action on an armature member 88 in said switch. The relay 8! is connected by wire 89 to the live wire 15. Thus the relay II energizes itself sufiiciently long to cause a magnetic impulse in electromagnet 28, which exists only momentarily because relay 8! breaks the main line at switch 14. In parallel with the relay H for rejecting slugs there may be an alarm or signal designated 90.
For accepting a coin similar units are provided for the various denominations- One will be described as illustrative. The five-cent denomination is selected. The 5 contact 39 is connected by wire 9| to relay 92 which is also connected by wire 93 to live wire 15. Armature 94 for the relay is connected by wire 95 to the control power line 13. Contact 95 and wire 91 serve to connect the armature 94 to wire 9| for continuing energization of the relay as the coin is removed. Contact 98 and wire 99 serve to connect the armature 94 to bus-bar I00, which is common to the acceptance relays, and which connects with the acceptance electromagnet 29. Contact I! and wire I02 serve to connect the armature 94 to mechanism generally indicated at I03 associated with crediting devices (not shown) whereby each specific coin accepted is credited to an account. Within the mechanism I03 contact is made between wire I02 and a wire leading from such mechanism to wire 86, so that after the coin is credited or the operation for crediting it has been initiated, the relay 8! can attract armature 88, and open the switch 14 in the control power line 13.
In Fig. 1, the step is the receiving space for a 5 coin. The contact 8 is the receiving contact for a genuine 5 piece. The step 5 may be made slightly tapered, so that an oversize slug which might be used for a 5 coin will not drop as far down as a genuine coin, and will hence make contact with the upper contact I. A slug which is of less diameter than a genuine coin will drop lower and will make contact with contact 8. Contact 5 operates the acceptance relay 29, and contacts 1 and 8 operate the rejection relay 28.
Numerous changes and modifications may be made. For example, the contact plate 35 may be stepped or tapered, as shown in the diagrammatic view of Fig. 5, or otherwise formed, and the number sizes and arrangement of ,contacts 39 may be varied as desired. The machine may thus be adapted for coins of various realms, or for inserts of any particular character.
The bank of contacts 39 which has beenillustrated is merely exemplary of any bank of separate means upon which the coin or insert may be effective. By using the coin or slug as a bridging member for contacts, a quick operation results. However, each set can be a mechanical device operated by the insert, either to perform some operation, or to close an electric switch. In Fig. 6 such a bank of mechanical devices is shown, each of which acts on a switch, or forms a part of a switch. The bank shown is a combination of the mechanical devices and of the contacts bridged by an insert. The slugs may more readily be used as bridging members, but good coins must be protected against possible injury, as where the non-sparking parts of the relay above described are omitted.
In Fig. 6 the same finger I2 is shown. The
.metal contact plate '35 is shown on the base plate l0. The pins 0 are comparable to the 5 contacts 39 of Fig. 5' and are shown as connected in common to wire by wires Ill and H2. Contact plate 35 may be connected as in Fig. 5 to wire 13.
For the coins several tilting devices are employed, such as the metal triangular pieces H3, pivoted at H4. Each is so arranged that the weight of a coin causes its edge H5 to swing in, raising the other edge against a contact H6. A wire Ill connects the piece H3 to the power line 13 through resistance 12 so that these have the same potential as the plate 35. A pin H8 may be provided to prevent the edge H5 swinging in too far, so that undesired circuit closures are eflected. For example, if the edge 5 extends in too far, the weight of a small coin passing it may raise it with a momentum which will close the circuit, when the coin should pass without such closure.
Various other changes and modifications, omissions and additions, may be made without departing from the spirit and scope of the invention as defined in the appended claims.
