2~3 in general alignment with the fuel-air mixture passage from said carburetor for the flow of said fuel-air mixture therethrough; said frusto-conical mix-ing element being mounted in said mounting body by the disposition of said largest diameter coil in said aperture.
The above and objects and advantages of the invention are believed made clear by the following detailed description of an embodiment thereof, taken in conjunction with the accompanying drawings, wherein:
~la-i2~3 Figure 1 is a vertical cross-sectional view taken through a representative carburetor of an internal combustion engine, with parts in phantom and parts in elevation, and illustrates the operative disposition of the partially disassembled device of my invention therein;
Figure 2 is a top elevational view of the mounting body and mixing element of a device according to the invention;

Figure 5 is a cross-sectional view taken along line 5-5 in Figure 4;
Figure 6 is a top plan view of an intermediate or spacer member for the device; and Figure 7 is a cross-sectional view taken along line 6-6 in Figure 6.
Referring now to Figure 1 of the drawings, a representative carburetor for an internal combustion engine is indicated generally at 10 and is depicted in operative relationship with the intake manifold of an internal combustion engine as indicated generally a~ 12.
Although not, per se, forming part of the invention, the carburetor 10 will be readily understood by those skilled in this art to com-prise main body parts 14~ 16 and 18 which cooperate as shown to form a fuel-air mixture intake passage 20 for delivery of the fuel-air mixture to the intake passage 22 of the manifold 12.
A carburetor fuel bowl is indicated at 24, and is connected by a fuel passage 26 to supply fuel through jet 28 to venkuri no~zle 30 or mixture with the incoming air in manner well known to those skilled in this art.
A choke or butterfly valve is indi.cated at 32 and is operable to reduce the amount of air admitted to carburetor passage 20~ A throttle or bu~terfly ~6~253 valve is indicated at 34 and is operable to control the amount of the fuel-air mixture admitted through the carburetor and fuel-air mixture passage 20 to intake passage 22 of the intake manifold 12.
A device constructed and operative in accordance with the inven-tion is indicated generally at ~0 in Figures 1, 2 and 3, and comprises an adapting or mounting body 42 which is configured in the manner of the car-buretor body parts l6 and 18 and the carburetor mounting surface 43 of the intake manifold 12 to insure ready structural compatibility therebetween as discussed in greater detail hereinbelow. Although a wide variety of materials may bc utilized in the fabrication of mounting body 42, it is preferred that the same be fabricated from a material of good heat insulative properties, and it may here be noted that a strong synthetic resin material in the nature of "Bakelite" ~trademark) has proven particularly satisfactory in this regard.
Mounting apertures as indicated at ~4 and 46 are formed as shown adjacent opposite edge portions of the mounting body 42 and are sized in accordance with the size of the respective, spaced carburetor mounting studs 48 and 50 (Figure 1) which extend as shown upwardly from the carburetor mounting surface 43 of the intake manifold 12.
A circular aperture 52 is formed as shown generally centrally oE
the mounting body 42 and is sized and located in the said mounting body in such manner as to be dimensionally compatible and in alignment with the fuel-air mixture passage 20 in the carburetor 10, and with the upper terminus of the fuel-air mixture passage 22 in the intake manifold 12. A slight conicali~y, or reduction in diameter in the downward direction, is provided for the aperture 52 for purposes described in greater detail hereinbelow~
A mixing element is indicated generally at 54 and is fabricated ~rom a strip of an appropriate material, such as metal, which is preferably of generally rectangular cross-section. The mixing element takes the form of the depicted frusto~conical spiral, and comprises initial or mounting coils 56 and 55 which are sized and configured to fit closely as shown into the G~
slightly conical aperture 52 in mounting body 42 to prevent the mixing element 54 from falling downwardly through said aperture.
As depicted, the mixing element 54 comprises a number of addi-tional coils 62, 64, and 66 of deoreasi~g di~meter which extend downwardly from the mounting body 42 to terminate as indicated at 68 radially outwardly of the axis of the mixing element 54, thus result in the overall, frusto-conical, spiral configuration of the said mixlng element. Although, for purposes of illustration, the mixing element 54 is depicted as comprising somewilat over five coils, it will be readily understood by those skilled in this art that this number oE coils may vary in accordance ~ith the particular operational characteristics of the carburetor in which the mixing element 54 is utilized. Although the extent of the frusto-conicality of the mi~ing element 54 may vary as above, ~ representative ratio between the diameter of the element at the top or initial coil, and the diameter of the element at the bottom or last coil might, for example, be approximately 32/25.
A sealing gasket of any appropriate gasket material is indicated at 70 in Figures 4 and 5, and will readily be seen to comprise mounting aper-tures 72 and 74, and a generally central aperture 76 for the passage of the fuel~air mixture therethrough, all in the manner of the mounting body 42 of Pigure 2.
An intermediate or spacer element, which is preferably of the same material as mounting body 42) is indicated at 78 in Figures 6 and 7 and, in the manner of that mounting body and sealing gasket 70, will be seen to comprise mounting apertures 80 and 82, and a generally central aperture 84 for the passage of the fuel-air mixture therethrough~
Although the e~act number of sealing gaskets and/or intermediate or space members may vary from application to application depending on the configuration and performance characteristics of the carburetor with which the device is used, it will be noted that, in the representative application of Figure 1, three sealing gaskets as indicated at 70A, 70B and 70C, and one ~ 4 ~
~62~
intermediate or spacer member 78 are used. In this application, it is pre-ferred that the diameter of aperture 76 in sealing gasket 70s be just slightly smaller, as for e~ample one millimeter, that the aperture 52 in mounting body 42 to thus insllre that the sealing gasket will partially overlie the initial coil 56 of the mixing element 54 and firmly retain the latter in position within the aperture 42.
Assembly and operative disposition of the device ~0 for the application thereof of Figure 1 in~ermediate the carburetor 10 and intake mallifold 12 is believed self-evidently to comprise the disposition of the nlixing element 54 in aperture 52 on mounting body 42, and the subsequent, aligned d:isposition of sealing gasket 70C, the mounting body-mixing element combination 42-54, the sealing gasket 70B, the intermediate element 80, the sealing gasket 70A, and the carburetor body parts 18 and 16, respectively, as sho~n atop the intake manifold. Thereafter, assembly is, of course, completed by the tightening of the carburetor mounting studs 48 and 5~ fixedly to secure the carburetor 10 atop the intake manifold 12, with the respective sealing gaskets functioning to insure an hermetic seal between the mounting body 42 and the carburetor body part 18 and intake manifold 12 and thus insure that no leakage takes place into or around the device 40. In those ~0 instances wherein the device 40 is not furnished as standard equipment with the carburetor, but rather is added thereto as an option, it will be readily understood by those skîlled in this art that one-time-only recalibration of the carburetor jets may be required.
In operation, the device 40 functions to impart a powerEul vortex-like, whirling or mixing motion to the mixture as the same is drawn from the carburetor 10 through the mixing element 54O In addition, this vortex-like motion imparted as described to the fuel-air mixture attendant the passage thereof through the mixing element 54 functions to increase the velocity at which said mixture leaves said element for flow into and through the intake manifold passage 22 into the combustion chambers of the in~ernal combustion ~6%~ii3 engine. Fur-ther, the centripetal forces generated in the fuel-air mixture attendant the vo~tex-like motion imparted thereto as described by the mixing element 54 will significantly reduce surface contact of the mixture with the hot walls of the intake manifold 12; and this feature, combined with the heat-insulative properties of the moullting body 42, will function to reduce the temperature of the fuel-air mixture upon entry into the do~lstream portions of intake manifold passages 26.
The overall result of all of the above is that more complete combustion of the fuel is provided, with attendant increase in engine power OUtpllt for a given amount of fuel~ and corresponding decrease in en~ine fuel conslm~p~ion and in the amount of pollutants found in the engine exhaust gases.
Actual tests have, for example, established that a representative application of the device to the carburetor of an internal combustion engine has resulted in a reduction in fuel consumption of approximately 25%.
Although~ as discussed hereinabove, the basic dimensions and configuration of the spiral mixing element 54 may vary from application to application, representative dimensions and configuration therefor are a rectangular cross~section of 0.8 X 2.5 millimeters having a spiral tread of about 8 millimeters.
Although illustrated in conjunction with what may be termed a "single barrel~' carburetor, it will be clear ~o those skilled in this art that the device 40 would be e~ually applicable for use with "multi barrel"
carburetors, in which instances there would, of course, be one aperture 52 in mounting body 42 for each such carburetor "barrel,~ and one mixing element 54 operatively disposed as described in each o:F said apertures.

Referring now to Figure 1 of the drawings, a representative carburetor for an internal combustion engine is indicated generally at 10 and is depicted in operative relationship with the intake manifold of an internal combustion engine as indicated generally a~ 12.
Although not, per se, forming part of the invention, the carburetor 10 will be readily understood by those skilled in this art to com-prise main body parts 14~ 16 and 18 which cooperate as shown to form a fuel-air mixture intake passage 20 for delivery of the fuel-air mixture to the intake passage 22 of the manifold 12.
A carburetor fuel bowl is indicated at 24, and is connected by a fuel passage 26 to supply fuel through jet 28 to venkuri no~zle 30 or mixture with the incoming air in manner well known to those skilled in this art.
A choke or butterfly valve is indi.cated at 32 and is operable to reduce the amount of air admitted to carburetor passage 20~ A throttle or bu~terfly ~6~253 valve is indicated at 34 and is operable to control the amount of the fuel-air mixture admitted through the carburetor and fuel-air mixture passage 20 to intake passage 22 of the intake manifold 12.
A device constructed and operative in accordance with the inven-tion is indicated generally at ~0 in Figures 1, 2 and 3, and comprises an adapting or mounting body 42 which is configured in the manner of the car-buretor body parts l6 and 18 and the carburetor mounting surface 43 of the intake manifold 12 to insure ready structural compatibility therebetween as discussed in greater detail hereinbelow. Although a wide variety of materials may bc utilized in the fabrication of mounting body 42, it is preferred that the same be fabricated from a material of good heat insulative properties, and it may here be noted that a strong synthetic resin material in the nature of "Bakelite" ~trademark) has proven particularly satisfactory in this regard.
Mounting apertures as indicated at ~4 and 46 are formed as shown adjacent opposite edge portions of the mounting body 42 and are sized in accordance with the size of the respective, spaced carburetor mounting studs 48 and 50 (Figure 1) which extend as shown upwardly from the carburetor mounting surface 43 of the intake manifold 12.
A circular aperture 52 is formed as shown generally centrally oE
the mounting body 42 and is sized and located in the said mounting body in such manner as to be dimensionally compatible and in alignment with the fuel-air mixture passage 20 in the carburetor 10, and with the upper terminus of the fuel-air mixture passage 22 in the intake manifold 12. A slight conicali~y, or reduction in diameter in the downward direction, is provided for the aperture 52 for purposes described in greater detail hereinbelow~
A mixing element is indicated generally at 54 and is fabricated ~rom a strip of an appropriate material, such as metal, which is preferably of generally rectangular cross-section. The mixing element takes the form of the depicted frusto~conical spiral, and comprises initial or mounting coils 56 and 55 which are sized and configured to fit closely as shown into the G~
slightly conical aperture 52 in mounting body 42 to prevent the mixing element 54 from falling downwardly through said aperture.
As depicted, the mixing element 54 comprises a number of addi-tional coils 62, 64, and 66 of deoreasi~g di~meter which extend downwardly from the mounting body 42 to terminate as indicated at 68 radially outwardly of the axis of the mixing element 54, thus result in the overall, frusto-conical, spiral configuration of the said mixlng element. Although, for purposes of illustration, the mixing element 54 is depicted as comprising somewilat over five coils, it will be readily understood by those skilled in this art that this number oE coils may vary in accordance ~ith the particular operational characteristics of the carburetor in which the mixing element 54 is utilized. Although the extent of the frusto-conicality of the mi~ing element 54 may vary as above, ~ representative ratio between the diameter of the element at the top or initial coil, and the diameter of the element at the bottom or last coil might, for example, be approximately 32/25.
A sealing gasket of any appropriate gasket material is indicated at 70 in Figures 4 and 5, and will readily be seen to comprise mounting aper-tures 72 and 74, and a generally central aperture 76 for the passage of the fuel~air mixture therethrough, all in the manner of the mounting body 42 of Pigure 2.
An intermediate or spacer element, which is preferably of the same material as mounting body 42) is indicated at 78 in Figures 6 and 7 and, in the manner of that mounting body and sealing gasket 70, will be seen to comprise mounting apertures 80 and 82, and a generally central aperture 84 for the passage of the fuel-air mixture therethrough~
Although the e~act number of sealing gaskets and/or intermediate or space members may vary from application to application depending on the configuration and performance characteristics of the carburetor with which the device is used, it will be noted that, in the representative application of Figure 1, three sealing gaskets as indicated at 70A, 70B and 70C, and one ~ 4 ~
~62~
intermediate or spacer member 78 are used. In this application, it is pre-ferred that the diameter of aperture 76 in sealing gasket 70s be just slightly smaller, as for e~ample one millimeter, that the aperture 52 in mounting body 42 to thus insllre that the sealing gasket will partially overlie the initial coil 56 of the mixing element 54 and firmly retain the latter in position within the aperture 42.
Assembly and operative disposition of the device ~0 for the application thereof of Figure 1 in~ermediate the carburetor 10 and intake mallifold 12 is believed self-evidently to comprise the disposition of the nlixing element 54 in aperture 52 on mounting body 42, and the subsequent, aligned d:isposition of sealing gasket 70C, the mounting body-mixing element combination 42-54, the sealing gasket 70B, the intermediate element 80, the sealing gasket 70A, and the carburetor body parts 18 and 16, respectively, as sho~n atop the intake manifold. Thereafter, assembly is, of course, completed by the tightening of the carburetor mounting studs 48 and 5~ fixedly to secure the carburetor 10 atop the intake manifold 12, with the respective sealing gaskets functioning to insure an hermetic seal between the mounting body 42 and the carburetor body part 18 and intake manifold 12 and thus insure that no leakage takes place into or around the device 40. In those ~0 instances wherein the device 40 is not furnished as standard equipment with the carburetor, but rather is added thereto as an option, it will be readily understood by those skîlled in this art that one-time-only recalibration of the carburetor jets may be required.
In operation, the device 40 functions to impart a powerEul vortex-like, whirling or mixing motion to the mixture as the same is drawn from the carburetor 10 through the mixing element 54O In addition, this vortex-like motion imparted as described to the fuel-air mixture attendant the passage thereof through the mixing element 54 functions to increase the velocity at which said mixture leaves said element for flow into and through the intake manifold passage 22 into the combustion chambers of the in~ernal combustion ~6%~ii3 engine. Fur-ther, the centripetal forces generated in the fuel-air mixture attendant the vo~tex-like motion imparted thereto as described by the mixing element 54 will significantly reduce surface contact of the mixture with the hot walls of the intake manifold 12; and this feature, combined with the heat-insulative properties of the moullting body 42, will function to reduce the temperature of the fuel-air mixture upon entry into the do~lstream portions of intake manifold passages 26.
The overall result of all of the above is that more complete combustion of the fuel is provided, with attendant increase in engine power OUtpllt for a given amount of fuel~ and corresponding decrease in en~ine fuel conslm~p~ion and in the amount of pollutants found in the engine exhaust gases.
Actual tests have, for example, established that a representative application of the device to the carburetor of an internal combustion engine has resulted in a reduction in fuel consumption of approximately 25%.
Although~ as discussed hereinabove, the basic dimensions and configuration of the spiral mixing element 54 may vary from application to application, representative dimensions and configuration therefor are a rectangular cross~section of 0.8 X 2.5 millimeters having a spiral tread of about 8 millimeters.
Although illustrated in conjunction with what may be termed a "single barrel~' carburetor, it will be clear ~o those skilled in this art that the device 40 would be e~ually applicable for use with "multi barrel"
carburetors, in which instances there would, of course, be one aperture 52 in mounting body 42 for each such carburetor "barrel,~ and one mixing element 54 operatively disposed as described in each o:F said apertures.
