No. 217098, filed 01/12/1972, now abandoned for an Automatic Fire Extinguisher Means. The present application is an improvement wherein the specification drawings and claims have been improved with new matter concerning the proper explanation of the operation and specification of the invention. This invention has the capability to put out fires caused by furnaces, engines, electric motors, stoves, wiring, applicances and other general fire causes.
New and improved art of fire security devices are needed desperately to save needless loss of life and destruction of property from fires that can be prevented. There are more than 6,000 fires every day in the United States, more than l2,000 fire fatalities yearly, amounting to a life every 45 minutes. There are more than 900,000 fires a year and most of these are residential fires, these facts are conservatively presented.
This invention, an automated improved fire extinguisher performs a number of useful functions in detecting fires and smoke conditions, in putting out the fire, setting off an alarm and having communications capability of notifying the service company or fire authorities of an existing hazardous condition. After putting out a fire, it shuts off by itself and is immediately ready for instant use again automatically. Specific attention is directed to oil or other heating fires caused by heating plants in homes and factories, cooking facilities, blow-back explosions causing smoke and fire damages in homes, mobile home fires that cause major damage and loss of life. In all cases, a common factor is the necessary shutting off power supply and the fuel supply at an early point in the fire so that the fire is not fed or gets out of hand and spreads. Whether its the cause of electric, oil, natural gas, LP gas or other fuel, such fires require special equipment and treatment to combat it at an early stage. This invention combats the fire immediately after start, warns of the danger, calls the authorities and repairmen, puts out the fire and readies itself for another mishap, plus it-has the capability of handling more than one type of fire at a time with new and improved fire sprinkler heads where needed in special applications of the extinguisher that becomes a complete sprinkler system. Improper treatment of a fire will serve to spread the fire more rapidly and existing type equipment requires that the extinguishers be hand held and directed to the source of flame endangering the personnel using same. Smoke is another meaningful factor in loss of life and property, and claims paid annually by insurance companies are astronomical. This present invention has smoke handling capability in the form of smoke sensors and blower exhaust control in addition to high intensity lighting that can be seen in the thickest smoke conditions, operated by the extinguisher or seperately by having its own heat responsive sensor, battery power and electrical switch. New'and improved art of fire fighting apparatus such as found in this new invention will assist with firefighting residential and commercial fires having a distinct advantage by detecting the fire early and immediately taking a course of action to put out the fire while it calls for assistance.

The battery 30 provides constant source of power it is charged by the power inverter charger 34 which provides electrical power to the control panel 7 to equipment terminals 8 that is connected to double sensor relays 9 and 9A and 10 and 10A. In a fire situation heat or smoke will close the sensor circuit sending current back to the circuit terminals 8 where the current is distributed internally in the extinguisher to the electric valves that start the flow of extinguisher agents. At the same time the circuit control 7 sends a signal to the alarm 6, to the blower 35, to the tape receiver 11 that starts a tape recording through the telephone relay equipment 11. It turns off the electrical switch 13 to the furnace 14. When the extinguisher l is emptied the outside connection 31 continues supplying the necessary extinguisher agents. A seperate pipe 21 is shown delivering extinguisher agent to nozzle 24 located at a hazard. FIG. I 1 shows an electric valve 25 shutting off the fuel supply to 15. The disconnect of any equipment individually would be accomplished by manual switches 52 also shown in FIG. 11 and other drawings 0 by having said switches on the extinguisher 1 housing 7 where the electrical terminals 8 are readily available for such switches 52. In this manner any part of the system may be shut down if needing repairs or if less than a total fire system were required. FIG. 14 shows a timer settable so that a given time cycle may be employed prior to calling in firefighters, eliminating false starts. Depending upon the need the automatic fire extinguisher means I will call the service company or the fire department or both each having seperate master control switches.
FIG. 2 shows the automatic fire extinguisher 1 having component parts built into one integral unit. This adds portability, makes servicing easier by allowing the entire unit to be removed in one unit for repair or filling operation. The battery pack 30, the telephone relay ll-A (shown in FIG. I) would be built into the unit 1 or if desired, can be added as an accessory package having a gang plug polarized for quick connect, fire in sulated and placed near the extinguisher for protection of the package.
FIG. 3 shows the automatic fire extinguisher that illustrates an additional improvement by having a second supply tank 46 associated with the first tank inside 45 wherein each tank operates from seperate electric valves 25 and 26 where one or more nozzles would handle different different extinguisher agents for putting out different kinds of fires. The tanks 45 and 46 in FIG.
3 could be designed for easy replacement by quick connect means without having to dismantle or remove the entire unit in refilling. .FIG. 3 shows a fire protective door 37 having a peep hole 40 and a horn opening 41 with instructions 39 printed on the inside of the door 37. A second source of external supply is shown as 31, having carrying handles 38 optionally placed on the unit for handling. Double heat sensors 9 and 9A are shown in tandem preventing false starts.
FIG. 4 has been divided into six parts that are separately explained.
FIG. 4A is shown with 3 pivotable direction nozzles 24 connected to electric valves 25. One heat sensor 9 or 9A would turn on one or more electric valves 25 as required. Each valve 25 can be connected to different extinguishing agents to fight different fires also explained in FIG. 3. FIG. 4A shows the circuit control 7 and electric terminals 8 on the automatic fire extinguisher ll.
FIG. 4B is shown with one electric valve 25 operating any number of required nozzles 24.
FIG. 4C shows one form of motorized means having a motor 42, a belt or gear 48, a pulley 49, a bushing 50 to stabilize the top of the rotating pipe, showing a stuffing box 47 for attachment and rotation on a bushing therein.
FIG. 4D shows a pressure operated nozzle having a bushing 50 and a stuffing box 47. The nozzles 24 operate on a universal joint 23 therefore positionable to given hazard coverage as specifically needed.
FIG. 4E shows another pressure operated nozzle 24 on a joint 23 showing means for rotating the nozzle under pressure in part or full circle rotation. The flow ofextinguisher agents in liquid form under pressure will activate an actuating arm shown in the drawing and under spring return tension, and a circle guide ring also shown in the drawing with given stops adjustably set by the users needs in covering the hazard.
FIG. 4F shows another form of motorized means where the motor 42 is shown in example in torroidal form having a connection flange, a bushing 50 and ad justable nozzle 24 and joint 23. Various motor 42 arrangements would turn at desired speeds and further utilized with full and part circle turning nozzles 24.
FIG. 5 shows an electrical schematic control of smoke hazards by accessories in this invention illustrated by the wiring diagram. The battery '30 sends current through the wiring 19 as illustrated where one side from the circuit control is wired to all the appliances. The other side is connected to sensors 10 and 10A, double smoke sensors eliminating false starts that upon a smoke condition closes the circuit within the sensor 10 sending current to the other side of all the appliances and controls on the automatic fire extinguisher, or placed in the room, turning them on. After the smoke has cleared the unit shuts off by itself meanwhile the automatic fire extinguisher turns on a blower, shuts off the electric and after cycling, is ready to call firefighters or the service company depending upon how its programmed. Should heat occur, the fire extinguisher I will direct a flow of extinguisher agent at the flame source and call for assistance while it sounds an alarm for smoke or fire Warning occupants of danger immediately. The use and amount of delay of a cycle timer is optional and dependent upon its use, shown in FIG. 14.
FIG. 6 shows the automatic fire extinguisher means from an operational viewpoint in an example furnace room. The same type of coverage would easily apply to automotive engines, electric motors, storage areas, stoves and all other hazards that have one or more type of materials that will burn. Double heat sensors are shown for heat 10 and 10A and for heat 9 and 9A, relay switch 32 and manual reset switch 33 that control the on and off power switch 13 cutting off power supply. The battery is shown 30 supplying power to the electrical control housing 7 and to the equipment terminals 8, the charger unit 34 is connected to the AC by plug 59 shown in FIG. 10. Hazard conditions are met by placement of nozzles 3 and 4 at required spots connected to a pipe 21 carrying agents from the extinguisher 1 electric valve 25 and 26.
FIG. 7 is an electrical schematic plan for the operation of FIGS. 1 and 6 and the portable models shown in the other figures. The schematic presents a simple sound method of generally accomplishing the objectives of the automatic fire extinguisher means. FIGS. 1 through 6 have already shown the accessories in this diagrammatic view.
' FIG. 8 is a fragmentary view of a furnace showing a stack pipe 20 and a furnace 14 having a oil burner 15 connected to an oil pipe 61 that has attached to it a electric valve 25 which will cut off the fuel supply when attached to the control panel 7 in FIG. 1. Additional advantages are shown by disconnect switch sensors 51 placed at the usual advantage points that are subject to blow-back pressure and explosion damage that usually disconnects the parts. When the peep hole 60 experiences a blast it will disconnect the sensor and therefore signal the equipment into action. When the chimney pipe 20 disconnects, the premises is subject to severe smoke damage and fire with no means to detect the condition early and save life' and property. Should the oil burner disconnect or change its position it would also trigger the alarm mechanism into action. FIG. 8 shows another improvement in having electric switches on the water pressure inlet valves commonly used on all heating systems 53 where the electric switch circuit closes on a pre-set high limit condition and triggers an alarm or calls the repair service company. On minor faults, the service company would be called for immediate action while in each case the power is shut off by the invention, that must be reset manually in extreme hazard conditions.
FIG. 9 shows the accesories illustrated in previous drawings FIGS. 1 through 7 and a high intensity light 55 mounted in a housing 56 having an on-off switch 52. A high intensity light 55 or lights can be seen in smoke conditions therefore useful to this invention. The many accessories shown in FIG. 9 can be turned on by heat sensors 9 and 9A and by smoke sensors and 10A which turns on the light and shuts off the power to the system stooping the suuply of fuel and uncontrollable fire hazards.
FIG. 10 shows the accessories mentioned in figures previously explained, all placed in a control box 76 having electrical connect terminals 8 on top. The combination of heat sensor 9 and smoke sensor 10 high intensity lights 55, alarm 6, power shut off relay 32, battery 30 charger 34 telephone relay 11A, power AC input 59 and test switch 44 with indicating light shown.

Instructions are shown 39 and mounting brackets 12.
FIG. 11 shows an electrical schemetic having electrical wiring to the high intensity lights, disconnect sensors on the partial chimney pipe shown and shut off switches 52 on the accessories. It shows the wiring to the pressure water switches 53 and a flow switch 58 which is one form of detecting this overpressure and a gauge switch is shown as 57 which also can send a signal to give alarm notification of high boiler pressure that could be very dangerous, starting a fire. Also, an AC charging gauge 73. 7
FIG. 12 shows a common source of fires in homes and restaurants on cooking stoves 62 and hoods 63. The hood 63 has its own fire extinguisher and pressure sight gauge connected to a hand shut off valve and connected by pipes 17 to electric valves 25 and 26 that are connected to pipes 17 and to the nozzles 3. The heat and smoke sensors 9 and 10 are attached to the hood that has an alarm 6 and a relay 32. When a fire starts heat will rise and open the heat sensor which will in turn send current to the corresponding electric valve turning on the extinguisher agent to the hazard, ring the alarm and shut off the power supply to the stove where the fire originated from. It will also turn off the electric to the hood whether duct or ductless shutting off the power to limit the fire. The tape communications and battery power plus charger is shown in other modifications that would be employed here. FIG. 12 also shows a stove having all the advantages of separate nozzles at the ranges 65 a power shut off relay 32 and on off power switch 52 with clock 66 and hand controls 67 to operate the stove. It also shows a oven temperature danger switch 71 and a oven pressure gauge danger switch 72 on the oven door 68 which can be placed in any location. Both of the switches 71 and 72 will close at pre-condition settings sending a signal to the alarm and other equipment as needed. The same power supply 34, telephone relay 11A and battery 30 shown in FIG. 6 could be used on a stove fire.
FIG. 13 shows a separate stove with sensors 9 and nozzles 3 placed at the range 65 having attachment sensors 51 on the stove door 68 and on the bottom of the door. It shows two of many positions the fire extinguisher can be placed in 1 having a pressure gauge 5 and showing a special arrangement of one of many ways electric valves may be employed, operated by sensors, condition responsive to open the valve and discharge'extinguisher agents towards the fire. In this illustration there are six valves, with electric wiring from each electric valve separately. Again, the battery and other related equipment shown are part of the operational parts included therein.
FIG. 14 shows a fire extinguisher having electric valves placed at the top and lower ends for illustrative purposes. It has mounting brackets 12, pressure gauge 5, a extinguisher low pressure switch 74, shows five electric valves 25 and 26 in position with wiring.
FIG. '15 shows another fire extinguisher with mounting brackets 12, gauge 5, shut-off valve 64, flow relay 32, pipes 17 and 4, electric valves 25 and 26 in one of many positions.
FIG. 16 shows the automatic fire extinguisher attached to a handle 79, shaft 80, wheels 81 having a hook eye 82, temperature danger gauge 83 and pressure danger gauge 89, showing an improved form of portability by using wheels 81, by manual or power assist means not shown.
FIG. 17 shows an automatic fire extinguisher having a key lock 77 lifting flanges 84, lift strap 85, eye ring 86, hook 87 and cable 88 for lifting the fire extinguisher into a hazard area.
FIG. 18 shows a fire ladder truck 94 as an example having a ladder 93 in a raised position having a track 91 attached to the ladder 93 shown with an extension 97, having a fire extinguisher 1 attached to a wheel operating on track 91, extinguisher 1 having an eye ring 86 nozzles 3 and 4 a pressure gauge 5 a cable control 92 for moving said extinguisher on track 91. An alternate position for the cable control means 92 is shown at the base of the ladder 93 on the fire truck 94 for moving the extinguisher from below. Such does not preclude hydraulic equipment doing the moving of said extinguisher into a fire hazard. A hydrant 96 having a hose attached 95 is shown connected to the extinguisher 1 supplying extinguisher medium from below, if required.
The various automatic uses of the automatic fire extinguisher having wheels or capability for placement into a hazardous area will save lives and property. Further, the temperature danger switch 83 and the pressure danger switch 89 shown in FIG. 16 would carry valuable firefighting information back to the control area relative to pressure and temperature conditions in a fire for evaluation whether to send in personnel. This would help the firefighters with valuable information concerning the danger values and to the progress of the fire, at the fire. Wiring and wireless units would relay the information to a ground control unit shown as FIG. 16 A, having two danger gauges with attached switch means for connecton to the wiring or wireless units to the fire extinguisher.
The automatic fire extinguisher or any combination of its parts will produce an early alarm of heat, fire, pressure and smoke which is important in stopping it. Further, the shutting down of power supply or fuel lines such as in oil burners, gas heat, engine fuel and other fuel fed hazards will also limit the size of the fire rather than feed it. The automatic use of a fire extinguisher that will direct a flow of agents at a hazard automatically will stop many fires and shut itself off. Such an extinguisher using a communications system to call firefighters and service companies saves time in letting the fires get out of hand and allows quick repairs getting back to normal. The use of attchment sensors to detect blowbacks and explosions and take early action will save millions in smoke damages and the lives of many people. Temperature and pressure gauge danger switches will also assist in kitchens where many fires originate. The use of water pressure valves having high pressure switches will result in immediate service calls, particularly on oil burners and heating plants to correct this condition before it gets to the explosion or fire stages. The use of heat operated high intensity lights in conjunction with the alarms and sensors will allow people to see in thick smoke conditions, saving lives, showing them the exits. The use of new sprinkler heads on the automatic fire extinguisher will give the kind of spray coverage needed for different hazards. The use of this automatic fire extinguisher with additional supply tanks or outside supply means will allow the fighting of more than one kind of a fire at one time from different tanks in the same apparatus. The placement of amoke sensors will start the blower operation to remove smoke and shut off the system. The advantages are many, there are too many fires that destroy property making insurance expensive. This automatic fire extinguisher presents a complete fire sprinkling system responsive to directional flow of agents according to the placement of sensors that operate individual electric valves.
When a fire starts, it begins to consume the oxygen we need to breathe. In the process of burning, carbon gasses are given off similar to an automobile engine giving off exhaust gasses. Next, the air becomes heated to a point where the superheated air and poisonous gasses are ten times deadly as the fire itself. Fire department statistics state that, fire in a home spreads 1,000% or more in the first 4 minutes, so we have 4 minutes to do something about a fire before it destroys life or property. For every thousand people that die in fires, over 800 are trapped because they didnt discover the fire in time to save themselves or their children. One breathe of superheated air will scortch your lungs just as boiling water will burn your flesh. Most fires can be divided into three classes, each class of fire must be fought in a different manner. Class A fires are those involving wood. paper, rubbish and other ordinary combustibles. Most fires fall into this class, they may be put out by directing a stream of water at the base of the fire. In such hazards, the new automatic fire extinguisher would be connected to a external water supply controled by an electric valve battery operated. Class B consists of those fires in which a flammable liquid such as gasoline or grease is burning. Water often causes such fires to spread, they could be smothered by covering them with I something that will remove their oxygen supply. Sand dirt or baking soda are effective extinguishing agents. Firefighters use a foam solution that covers the entire fire area with a thick blanket that resembles soapsuds. Class C includes all fires that involve live electrical equipment. Only extinguishing agents that do not conduct electricity should be used to fight such fires. Baking soda and sand may be used but water should never be used. In a room such as illustrated in FIGS. I and 6 we have electricity, oil, building materials and water pipesthat could break and easily spread a fire rapidly that is why more than one agent capability is important. The placement of the sensor 9 in circuit with the elec tric valve 25 will direct a specific material to a nozzle placed at a specific hazard. The special fire extinguish ers that have been designed to todays use require human handling until firefighters reach the scene with professional equipment whereas this new invention will act immediately and assist firefighters. No one should use flour or starch on a fire, they explode. Boiling water is 212 F. but superheated air can build up to hundreds of degrees causing almost everything to burn. Therefore one breathe can cause instat death. Its been reported that of all tragedies occur at night. During the day you would probably smell smoke or see the flames in time to escape. But at night the whole picture has changed, while sleeping we lose the warning time that allows a fire to take-over and limits the time to es cape from a burning house. About 85% of all deaths occur between l0 PM and 6 AM and 4 minutes is not very much time to gather our senses, get the children and others organized to escape deadly'gasses and superheated air of 400 to 800 F. In other instances while on vacation the property is without any means of warning allowing complete destruction of property. Whether home or away, this automatic fire extinguisher means will perform the necessary functions to lengthen the time between alarm signal and safe time to escape while it puts out or contains a fire in an area until the firefighters arrive. It may also provide insurance in places that heretofore were risks where in the many forms of accessories it provided a new automatic fire sprinkler and a new fire extinguisher having tremendous advantages over the old art.
