The owners of this type of apparatus are often not the proprietor or manager of the es tablishments where the apparatus is located. Therefore, there is always a danger that the owner may not be receiving full compensation for the use of his equipment.

Apparatus of this type does, of course, presently have various safeguards built in to protect the owner. How ever, experience has shown, particularly in automatic car washes, that present safeguards can be and are readily defeated. Thus, the apparatus is utilized and the owners are not paid for this use. This invention insures a count each time the apparatus is utilized.

SUMMARY OF THE INVENTION An electrical impulse counter system particularly adaptable to automatic car wash apparatus is disclosed. Each time an automobile enters the car wash, a count is registered on the counter. The system is so designed that the pump motor for the wash water or other motor of the car wash system cannot be energized until the counter is energized. Power is not applied to the motor until the counter is energized. Thus, the car wash cannot be used until the counter itself is energized to register a count.

The counter and the components directly associated with the energization of the motor and counter are housed in a tamper-proof box and power is brought to the box by means of an armored cable or the like. One must break open the box or cut through the cable to defeat the counter system of this invention. Of course, such destruction is immediately apparent to the owner of the car wash.

While the invention is specifically described as being applied to an automated car wash, it can also be applied to any apparatus where electrical power must be applied to a motor or other device to operate the apparatus; for example, electrically operated vending machines. This will, of course, be apparent to those skilled in the art.

BRIEF DESCRIPTION OF THE DRAWING A clear and concise understanding of the structure and operation of the invention can be obtained from the following detailed description of the invention when read in conjunction with the annexed drawing in which the single FIGURE shows a preferred embodiment of the invention.

DESCRIPTION OF THE INVENTION The single FIGURE of the drawing shows a preferred embodiment of the invention as it is utilized in an automatic car wash system. An automatic car wash system is one in which an automobile passes through the system and is washed and dried mechanically. That is, no human labor is necessary to perform the operation of washing the car. Many of these systems are coin operated. If one wishes to clean his automobile in such a coin operated system, he merely drives the car into the car wash, inserts the proper amount of money, and the system automatically processes the car through the various steps of the system. At the end of the system there is generally a lever or wand that is tripped to shut down the car wash apparatus. While the embodiment of the invention as shown is described as being applied to an automatic car wash, it will be appreciated by those skilled in the art that the apparatus of such a car wash system is similar to the apparatus of a non-automatic conventional car wash. Thus, the invention as shown could be applied directly to these other car wash systems.

Referring to the drawing, the electrical conductor 1 is connected between the tenninals L and T, through a contact 2 and a fuse 7 and the electrical conductor 2 is connected between the terminals L and T through the contact 4. Similarly, the electrical conductor 3 is connected between the terminals L and T through the contact 6 and the fuse 5. Terminals L L and L are connected to a source of three phase power (not shown). The power applied to terminals L L and L is generally 240 volts, three phase. A three phase AC motor (not shown) is connected to terminals T T and T;,. For purpose of this description, the motor connected to terminals T T and T is assumed to be the car wash water pump motor. This motor is conventionally a three phase motor and the operation of this motor is an essential step in wash operation. As will be apparent later, this invention can'be used in cooperation with other motors of the car wash system.

The conductors, terminals, contacts and fuses mentioned above are all conventional elements of the starter circuitry of a car wash pump motor. As shown in the FIGURE, this starter circuitry also includes a motor starter coil 11 and the contact 9. In the conventional automatic car was system one side of starter coil 11 is connected directly to the conductor 13 and the other side is connected to the conductor 15 through capacitor 9 as shown. Conductors l3 and 15 are connected to the control circuits (not shown) of the car wash system. In a coin operated system, insertion of the proper amount of coinage closes a switch. Closing of this switch places volts, single phase, on

lines

13 and 15, thereby closing contact 9, energizing starter coil 11 and thus closing contacts 2, 4 and 6 to start the motor. Contact 9 is actually a voltage responsive switch.

The apparatus and operation just described are that of a conventional automatic car wash system. As shown in the FIGURE, one side of starter coil 11 is not directly connected to conductor 13 as is the case in a conventional system, but is rather coupled to conductor 13 through the apparatus of this invention. Basically, the apparatus of the invention comprises an impulse counter 8 and a relay 16 having a coil 14, the

switch arm

22 and 24 and

contacts

10 and 12. One side of motor starter coil 11 is connected to contact 12 of relay 16. The other side of motor starter coil 11 is connected through contact 9 to conductor 21, which in turn is connected to conductor 15. Thus, starter coil 1 1 is essentially connected directly to conductor 15 through contact 9. As was mentioned above, this side of starter coil 11 is conventionally connected to conductor 15 through capacitor 9. Conductor 21 is also connected to one side of relay coil 14. This same side of relay coil 14 is also connected to one side of counter 8 by means of the conductor 25. The other side of counter 8 is connected to contact of relay 16 by means of the conductor 27 and the other side of relay coil 14 is connected to conductor 13 by means of the conductor 23.

Relay l6 and counter 8 are shown as being mounted inside an electrical box 17. Electrical box 17 is a heavy duty conventional type steel utility box. The box has a cover (not shown) which is closed and sealed or locked. The cover may have a small glass window that permits one to read counter 8 without unlocking or unsealing the box.

Conductors

19, 21 and 23 are the conductors of an armored cable or the like and the cable is brought into box 17 in such a manner that the cable and conductors cannot readily be tampered with or removed from box 17. Conductor 25 which is shown as being partially outside of box 17 is actually totally inside the box. Thus, counter 8, relay 16 and the conductors connected to these devices are essentially tamperproof. One cannot readily gain access to box 17 and thereby bypass counter 8. Of course, one could cut the conductors or break open box 17, but such damage would be readily apparent.

Now that the apparatus of the invention has been described, the operation will be described. Assume that one wishing to use the system has deposited the proper amount of money; then power will be applied to conductors l3 and 15. Energizing conductors l3 and 115 energizes relay coil 14. When relay coil 14 is energized,

arms

22 and 24 of relay 16 close on

contacts

12 and 10, respectively and contact 9 closes. When

relay arms

22 and 24 close on

contacts

12 and 10, power is applied to counter 8 and to starter coil 1 1 since contact 9 is also closed. When starter coil 11 is energized, contacts 2, 4 and 6 are closed, thereby applying a voltage to terminals T,, T and T to run the motor. Counter 8 is an electrical impuse counter. When the power is applied to the counter, a count is initiated. However, since this is an impulse counter, the count is not completed until the power is again removed from the counter.

With the pump motor running, the automobile can now proceed through the car wash. As was mentioned, automatic car washes are generally equipped with a lever or wand switch that is actuated by the automobile as is passes over the lever or wand. This switch is connected in either conductor or 13 and open circuits the conductor in which it is connected when actuated by the automobile. Thus, when the automobile passes over the lever or wand switch, relay coil 14 is deenergized and relay

arms

22 and 24 move off of contacts l2 and 10, thereby disconnecting conductor 19 which is connected to starter coil 11 and conductor 27 which is connected to counter 8 from line 23. Thus, deenergizing relay 14 also de-energizes starter coil ll 1 and removes power from counter 8. De-energizing starter coil 11 opens contacts 2, 4i and 6 to shut down the pump motor and removing the voltage from counter 8 completes a one count on the counter. As was mentioned above, counter 8 is an inpulse counter and the count is not complete until the power is removed from the counter.

From the foregoing description it is quite obvious that a count will be registered each time the car wash is operated. In the embodiment shown, the pump motor and counter are energized. simultaneously. Relay l6 must be energized before any power can be applied to the motor and energizing this relay also applies power to the counter. Furthermore, the relay and counter are sealed to prevent one from bypassing the counter system. It should also be obvious that the relay and counter arrangement could be utilized with other motors of the car wash apparatus and could also be used in other systems, such as vending machines. For example, relay R4 and counter 8 could be used with an electric cigarette machine such that the motor which turns the apparatus to drop a pack of cigarettes is controlled by the relay-counter combination. in addition, it will be obvious to those skilled in the art that various changes and modifications can be made to the embodiment shown and described without departing from the spirit and scope of the invention as defined in the appended claims.
