Field of the Invention This invention relates to a vending or dispensing machine and, more particularly, to a vending machine which is used with and operable in response to an insertion of a predetermined token or coin other than coins in circulation and in which the coin inserted is melted or burnt away.

2. Description ofthe Prior Art Generally, a vending machine for goods is located on a street or in front of a store. When one wishes to buy an article, he inserts coins corresponding in value to the article to dispense it. The coins deposited into the machine are accumulated in a coin receiving container disposed therein. Thus, there is the risk that the accumulated coins will be stolen. In addition, the prior art vending machines require that the accumulated coins be collected. A useful number of machines of this kind will result in an increase in personnel expenses for coin collection.

It is also known that hospitals and rooms of hotels are sometimes provided with automatic gas or electricity-supplying devices operable in response to an insertion of coins to automatically supply a corresponding amount of gas or electricity. These devices also have the feature that the inserted coins are accumulated therein. Thus, the requirements involved in the collection of the accumulated coins cause an increase in personnel expenses in service businesses of this kind.

Further, it is conventional that the quantity of electricity, gas or water domestically used within a period be recorded relying on the inspection of. an indicating meter located in each home and that the record is utilized as a basis for calculating the charge. This system requires a visit to respective homes so as to inspect the meter and collect money and, therefore, an increase in number of homes serviced results in an increase in the work involved in meter inspection and money collection and, hence, in the personnel expenditure.

It is therefore, an object of the present invention to prevent the coins accumulated within a service-affording vending machine from being robbed as well as to eliminate troubles conventionally involved in the collection of accumulated coins, by melting or burning away the inserted coins or tokens after they have been evaluated.

Another object of the invention is to provide an automatic supplying apparatus in which the switch or the valve for feeding or supplying electricity, gas or water operates to supply same in response to the coins inserted and when the quantity of the material for the value of the coins inserted has been dispensed, the switch or the valve operates to stop the supply while the coins inserted are melted or burnt away so as to save the trouble involved in the inspection of meters and in the collection of money.

In brief, these and other objects are achieved by using special coins and having a coin-judgment means and an articledispensing means or a device for controlling gas or electricity and adding a coin-destruction means such as an electric heater or a container of acid or other solvent.

These and other objects will be more fully understood from the following description taken in conjunction with the following drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram illustrating the structural relationship of the vending machine according to the present invention,

FIG. 2 is a cross-sectional view illustrating an embodiment ofa coin treating meansutilized in the vending machine, and

FIG. 3 is a diagram illustrating the general arrangement of the apparatus for automatically supplying gas, electricity or water, according to the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 diagrammatically illustrates the structural relationship in the vending machine of the present invention which comprises a coin-judgment or sensing means 1, a delivery means 2 for responding to the signals received from the coinjudgment means 1 to deliver articles one after one, and a destruction means 3. The coin judgment means 1 is conventional and a so called coin selector mechanism" which functions to judge the coins inserted as to whether they are the predetermined ones and to feed a signal to the article-delivery means 2 when the inserted coins are proper ones and which rejects the coins and returns them from the vending machine when they are not the proper ones.

Similarly, the article-delivery means 2 is conventional, responding to the signal from the coin-judgment means 1, to deliver articles equivalent in value to the inserted coins from the delivery or outlet opening of the vending machine, using for example, a clutch mechanism.

The relationship of the coin-treatment means 3 which forms a major part of the invention, relative to the coin-judgment and goods-delivery means 1 and 2 corresponds to the relationship of the coin container relative to the corresponding means in the conventional vending machine. In other words, the inserted coins are allowed to fall down into the coin-treatment means 3 in the case where the coins are the correct ones. The coins used with the machine of the present invention are made from a meltable, soluble or combustible material and the pieces which have fallen into the coin-treatment means 3 are melted, dissolved or burnt away.

An embodiment of the coin treatment means 3 is shown in vertical section in FIG. 2, which shows a housing 31 within which is disposed an inclined heating plate 32. A heating means, for example, a coil of nichrome wire 33, is provided beneath the heating plate 32 to heat the latter. The coil of nichrome wire 33 may be continuously fed with electrical power, or alternatively, the electrical power to the coil 33 may be controlled, for example, by a switch mechanism each time a coin falls. Further, the coil of nichrome wire 33 may be supplied with electrical power at predetermined intervals irrespective of the presence or absence of coins.

The coins that fall from the coin-judgment means 1 enter the housing 31 through an inlet 34 shown in FIG. 2 dropping onto the heating plate 32. The latter is heated by the coil of nichrome wire 33 and melts or burns away the coins falling thereon. The molten material or gases produced at this time are respectively delivered or exhausted out from the housing 31 through the apertures 35 and 36 provided therein. In FIG. 2, in order to destroy the fallen coins, coins other than the usual coins in circulation are used to operate the various kinds of vending machines. Thus, the coins used with the machines of the present invention are formed from meltable or combustible resinous material or metallic material and the user of the machine is required to buy such coins beforehand for a fixed price.

The embodiment shown in FIG. 2 is designed for melting or burning the pieces by application of heat. This embodiment may be so modified that sulfuric acid, nitric acid or aqua regia formed from them is contained within the housing 31 to chemically treat the pieces falling thereinto.

FIG. 3 diagrammatically illustrates an embodiment of the system for automatic electricity-supplying apparatus according to the present invention. The apparatus comprises coinjudging means 1, coin-destruction means 3, a wattmeter 4 and switch means 5. The coin-judging means and coin-destruction means are the same as previously described with reference to FIGS. 1 and 2. The power input lines are connected to a load 8 through the wattmeter 4 and the switch means 5. The wattmeter 4 functions to supply a signal through a line 6 to open the switch 5 when a quantity of electricity corresponding in value to the inserted coins has been supplied to the load 8. In other words, the wattmeter 4 is a kind of preset counter. The coinjudgment means 1 functions to feed a signal through a line 7 to the switch means 5 to close the switch when proper coins have been inserted thereby actuating the switch means. Also, the coins inserted, if they are proper ones, are delivered into the coin-treatment means 3 in a manner similar to that described in conjunction with FIG. I.

Now, a description is made hereunder with respect to the operation of the, apparatus shown in FIG. 3. When proper coins are inserted into the coin-judgment means 1, the signal fed through the line 7 actuates the switch means 5 to close the switch conduct. A user of the apparatus then closes a switch 9 so as to provide the load 8 with electrical power with the result that the wattmeter of the preset counter 4 operates. When the wattmeter integrates the supply of electrical power corresponding to the value ofthe inserted coins, the meter sup plies a signal through the line 6 to the switch means 5 to open the switch and thereby stop the electrical supply to the load 8.

In FIG. 3, when the load 8 does not require the entire quantity of the electricity which corresponds to the value of the inserted coins, the switch 9 may be opened to stop the electrical supply to the load 8. In this case, however, the value integrated in the wattmeter 4 has not yet reached the preset value, i.e. the electrical quantity corresponding to the value of inserted coins, and thus, no signal is fed to the line 6. Thus, switch means 5 remains closed. Therefore, when the remaining part of the electrical power is required, a mere closing of the switch 9 is sufficient for this purpose. When the remaining part of the electrical power has entirely been supplied, the switch means 5 is opened by the signal from the line 6.

Furthermore, the coin-judgment means 1 delivers the coins inserted to the coin-treatment means for melting, dissolving or burning away the coins only when the coins are correct ones.

In the foregoing description, it has been assumed that the wattmeter 4 is preset for delivery of a predetermined amount of electric power when coins of the proper value are inserted in the coin judgment means 1. If it is desired to provide for delivery of different amount of power as desired by the customer, the coin-judgment means includes coin-evaluating means and is connected to the wattmeter 4 by a line 10 so as to supply a signal to preset the wattmeter for delivery of an amount of power corresponding to the value of the coins inserted. When the wattmeter has supplied the selected amount of power to the load 8, it sends a signal through the line 6 to open the switch means 5.

FIG. 3 shows an embodiment wherein the present invention is utilized for an electrical-power-supplying apparatus. It is, however, readily appreciated that the principle of this embodiment may be similarly applied to a gas or water-supplying apparatus. It will be apparent that this modification requires a replacement of the wattmeter 4 by a suitable gas or water meter and replacement of the switch means 5 of the described embodiment with suitable valve means.
