ATTORNEY nited States Patent 9 GAS PRGDUCING APPARATUS John B. Brower, Hialeah, Fla. Application June 25, 1954, Serial No. 439,238
1 Claim. (Cl. 137-391) The present invention relates to a gas producing apparatus and it consists in the combinations, constructions and arrangements of parts herein described and claimed.
Generally there is provided a gas producing apparatus which essentially consists of a gasoline supply tank, an agitator tank and a gas supply tank. Novel means is provided for maintaining a constant level of liquid gasoline or fuel oil in the intermediate or agitator tank from the gasoline supply tank. The gaseous product emanating from the intermediate or agitator tank is lead to a compressor from whence it is fed to the gas supply tank. One of the features of the invention is the provision of a novel agitator which is mounted in the agitator tank. Another feature of the invention is the provision of a pair of motor-operated pumps which are designed to maintain a proper level of liquid in the agitator tank and which are controlled by novel means in the agitator tank. Various of the other features of the invention will be brought out in the appended specification.
It is accordingly an object of the invention to provide a gas producing apparatus which is simple in construction, inexpensive to manufacture and yet effective and efficient L1 use.
Another object of the invention is to provide, in an apparatus of the character set forth, novel means for maintaining a constant level of liquid in an agitator tank forming a part of the invention.
Another object of the invention is to provide, in a apparatus of the character set forth, a novel agitator forming a part of the invention.
A further object of the invention is the provision, in an apparatus of the character set forth, of means for pro ducing a novel and useful combustible gas from gasoline, or fuel oil.
A still further object of the invention is to provide, in an apparatus of the character set forth, novel means for controlling a pair of pumps forming a part of the invention.
Another object of the invention is to provide a novel method of producing combustible gas.
Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawing, in which:
Figure l is a schematic view, partly in elevation and partly broken away, illustrating an apparatus in accordance with the present invention,
Figures 2 and 3 are schematic views illustrating electrical circuits involved in the operation of a motor controlling switch forming a part of the invention, and
Figure 4 is a sectional view taken along line 44 of Figure 1.
Referring more particularly to the drawings, there is shown therein a gasoline supply tank mounted upon a suitable platform 11. A pipe 12 extends from a point adjacent the bottom of the tank 10 upwardly through a fitting 13 to connect with a pump 14 mounted upon a platform 15 or the like. Adjacent the pump 14 there is mounted upon the platform 15 an electric motor 16 2 which is connected to the pump 14 by means of a drive shaft 17.
A pipe 18 similar to the pipe 12 connects the tank 10 with a pump 19 likewise mounted upon the platform 15. Adjacent the pump 19 there is mounted upon the platform 15 an electric motor 20 which is connected by a drive shaft 21 with the pump 19.
A pipe 22 interconnects the pump 14 with the lower end portion of an intermediate or agitator tank 23 while the pipe 24 interconnects the pump 19 likewise with the lower end portion of the tank 23.
The tank 23 is provided with a removable cover 25 which is adapted to be fastened atop the tank 23 by means of bolts 26 and wing nuts 27 in conventional manner. The tank 23 is provided with a conventional sight gauge 28 whereby the level of gasoline or fuel oil in the tank 23 may be ascertained at all times, such level being indicated in the drawing at 29.
A motor-control switch is generally indicated at 3%) and is mounted atop the cover 25 and is interiorly provided with a pair of contacts 31 connected by wires 32 to the motor 20 to a suitable source of electrical energy indicated at 33. The switch 30 is also provided at its lower end with a pair of contact members 34 which connect by means of wires 35 with the motor 17 having in circuit a suitable source of electrical power 36. A float 37 is adapted to be buoyantly supported by the liquid 29 and is provided with an upwardly extending shaft 38 provided at its upper end with a movable contact member 39 which is adapted to selectively contact the contact members 31 and the contact members 34.
A vapor supply pipe 40 interconnects the tank 23 through the cover 25 with a compressor 41 mounted upon a suitable platform 42. The tank 23 is shown as being supported upon a standard 43 which is affixed to the platform 15 but it is to be understood that the various portions of the present apparatus may be mounted wherever convenient or desirable and are shown in the drawings schematically for the purpose of better illustrating the same. An electric motor 44 is likewise mounted upon the platform 42 and is connected with the compressor 41 by a drive shaft 45.
A gas supply tank 46 is mounted upon a suitable platform 47 and is connected with the compressor 41 by means of a pipe 43. A check valve 49 is mounted in the pipe 48 adjacent to the compressor 41.
A pressure-operated switch 50 is shown mounted atop the tank 46 and connected thereto by means of a pipe 51. The switch 50 is connected with the motor 44 by a pair of wires 52 one of which is connected through a source of energy indicated at 53. A pressure gauge 54 is likewise mounted atop the tank 46 and connected thereto by a fitting 55.
A pair of gas supply pipes 56 is shown connected to the tank 46 and each has mounted therein a pressure reducing valve 57, preferably of the diaphragm type. An air supply pipe 58 extends vertically through the cover 25 into the tank 23 to a point adjacent the bottom thereof where it is connected by means of a Y-joint 59 with a pair of divergent agitator pipes 60 each provided upon its lower side with a plurality of minute openings 61. The upper end of the pipe 58 has mounted thereon an air cleaner 62 and, between the cover 25 and the cleaner 62 the pipe 58 is provided with a check valve 63. The tank 10 is adapted to contain a quantity of gasoline as indicated at 64.
In operation, it will be apparent that the agitator tank 23 is adapted to contain a quantity of gasoline or fuel oil 29 therein at all times, being supplied with such gasoline from the tank 10. A constant and predetermined level of gasoline or fuel oil, as indicated at 29, is maintained within the tank 23 through the operation of the switch 30, it being apparent that should too great a quantity of gasoline be present within the tank 23, that the float 37 will rise and consequently through the shaft 38 bring the movable contact member 39 into contact with the contact members 31 thus closing a circuit to the motor 20 to thereby put into motion the pump 19 which is designed to pump liquid from the tank 23 to the tank 10.
Likewise, it will be apparent that should the level 29 become too low, the fioat 37 and consequently the shaft 33 and movable contact member 39 will all move in a downward direction to thus bring the movabie Contact member 3% into contact with the contact members 34 thus completing an electrical circuit to the motor 16 which, being connected to the pump 1%, will cause the latter to supply gasoline from thetank 10 through the pipe 22 to the tank 23 to thus bring the level again to a proper height. incidentally, the physical level the gasoline within the tank 23 may be viewed at all times through the gauge 28.
it will also be seen that when gas within the tank 36 reaches a predetermined low pressure, that the motor will be caused to operate by means of the switch thus causing the compressor 41 to pump additional gas or vapor from the upper end of the t r11 23 through the pipes 40* and 48 to the tank 46, the check valve 4 preventing any possible back fiow through the pipe 48 to the compressor all. been reached within the tank 46, it will be apparent that the switch will act to again cut oh the motor 44 and consequently stop the operation of the compressor i1.
During the operation of the compressor 41 it will be apparent that fumes emanating from the gasoline or fuel oil 2? within the tank 23 will be drawn through the pipe 49 thus creating a very low pressure within the tank 23 and thereby causing air to pass through the air cleaner 62, the check valve 63 and eventually downwardly through the openings 61 in the agitator pipes-60. This air emanating from the openings 61 will pass upwardly through the mass of gasoline 29 thus to create additional fumes of an extremely combustible nature which will, in turn, be drawn ofi through the pipe 40 as above described.
When a predetermined pressure has delivered to the tank 46 and eventually through the pipes 56 is of extremely high B. t. u. rating and that the gasoline remaining in the tank 23 after'continued production of fumes and vapors as aforesaid, has been improved in anti-knock rating.
While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the appended claim.
What 'is claimed is: I
A device of the character described including a first tank, means for maintaininga constant liquid level in said first tank, and a second tank, said means comprising a float-controlled switch mounted in the upper end ofthe first tank, a pair of electric motors, a pump connected to each of said motors, a float adapted to be buoyantly supported by liquid in said first tank, means in said floatcontrolled switch operable by said float to selectively operate said motors, said pumps each interconnecting said first tank with said second tank, one of said pumps adapted to supply liquid to and the other of said pumps adapted to remove liquid from said first tank.
