FUEL SAVER FOR INTERNAL-COMBUSTION ENGINES.

To all whom it may concern i Be it known that I, Eowann'B. FARGO, a citizen of the United States residing at Los Angeles, in the county of Los Angeles and State of Ca 'fornia, have invented new and useful Improvements in Fuel Savers for Internal-Combustion Engines, of which the following is a specification.

This invention relates to fuel savers for internal combustion engines,-and has for its object the provision of means for agitating the fuel supply to the carburetor of an internal combustion engine in order to break up the globules comprising the fuel so that when mixed with air in the carburetor complete vaporization of said liquid globules will occur.

It is a further object of the invention to provide means whereby heating of the fuel is caused during the agitation thereof.

It is a still further object of the invention to provide means for causing mixing of a lighter fuel with the fuel for the internal combustion engine during the agitation thereof. so as to form an intimate mixture of the two fuels prior to the carburation thereof.

The invention will be readily understood from the following description of the so companying drawings, in which Figure l is a side elevation of the internal. (.Oll'illllStlOll engine showing an improved fuel saving device employed in connection therewith.

Fig. 2 is a longitudinal section on the line 2 ofFig. l. I

Fig. 3 is a longitudinal section on the line 3-4; of Fig. 2.

The fuel saver is shown employed in connection with the usual internal combustion engine I having the intake manifold 52 leadi ug from the carburetor The exhaust manifold is shown at 1;. T he fuel saver is arranged in the fuel supply pipe leading to the fuel intake 5 of the carburetor and consists of a cylindrical casing 6 in spaced relation within an exterior cylindrical casing 4' so as to form a cylindrical passage 8 between said casings. A shaft 9 extends axially through the casings and is journaled in a bearing 10 formed as an axial connection between said casings.

At diametrically opposite points threaded nipples 11 are provided upon casing 7 and threaded openings 12 are arranged in alinement therewith in casing 6. A pipe 13 lead- Application filed August 17, 1920. Serial No. 404,202.

ing from a fuel supply tank is threaded into one of the openingsl2 and a pipe 14 leading to the fuel intake 5' of the carburetor is threaded into theopposit'e opening 12. The device is thus mounted in the fuel supply llIlQ llO. the carburetor. [A pipe 15 is threaded into one of the nipples 11' and isarranged in spaced relation" surrounding pipe 13. The pipe l5 leads to a sleeve 16 'surrounding the exhaust'pipe fand so arranged as to permit air to be drawn into said sleeve and intothe pipe 15. A similar pipe 17 is threaded into the opposite nipple 11 and is arranged in spaced relation surrounding pipe 14. This pipe leads to the air intake 18 ofthe carburetor.

A disc 20 is fired upon shaft 9 within i casing 6 by means of thei'pin 21, and the shaft and disc are arranged to be rotated as by a suitable driving connection including a pulley 31 fixed upon shaft 9 and a belt 32 passing over said pulley and actuated by any suitable rotating part of the engine. Radial pins 22 project beyond the periphery of disc 20 into the annular space 23 surrounding said disc within casing 6. These pins are arranged adjacent one end faceof disc 20, and a similar series of radial pins 94: are arranged adjacent the opposite end face of the disc. Transverse wires 25 extend from the lower end of a pin of one series to the upper end of a pin of the other series circumferentially beyond the first pin. By this arrangement a net wor: of crossed wires is provided between the radial pins 22 and 24. Pins 26 project radially inwardly from the casing 6 between the rows of pins 22-2 1 and into the space provided by the crossed wires between next adjacent pins.

Means are, preferably, provided for introducing a second fuel into the space 23 in order that a mixed fuel .may be supplied to the carburetor. For this purpose a pipe 27 leading from a tank, not, (shown, containing the second fuel may be inserted through casing 7 and threaded into casing 6. y

A chamber 28 for collecting the residue from the fuel supply to casing 6 may be connected to casing 6 by means of the threaded nipple 29 projecting therefrom through casing 7. The residue collecting chamber is provided with a usual drain cook 30.

In operation the hot. gases passing through pipe 4 will heat the air drawn into sleeve 16 and the pipe 15. The heated air will pass through the space 8 between casings 6 and 7 and thence through pipe l7 to the carburetor. The fuel entering the space Within casing 6 through pipe 13 will be agitated by the rotating disc 20, the crossed wires thereof co-operat-ing with the pins 26 to break up the globules of'thefuel and thoroughly churn the same.

If desired a second fuel maybe introduced through pipe 27 and the churning action within casing 6 will thoroughly mix the two fuels. The hot air passing through space 8 will cause heatingv'of-casingfi and of the fuel within the same so that the breaking up of; the fuel may be more readily accomplished. The fuel :is discharged through pipe 14 to the carburetor where the carburation of the air d-rawn'thereinto 'may i be readily accomplished due tothe pro-agitating and heating of the fuel.

Various changes may be made without departing from the spirit Of'thc invention as claimed.

What is'claimed is: v

1. In a fuel saver for internal combustion engines, an agitator comprising awca'si'ng member, a: rotatable member within the same, crossed wires projecting outwardly neaasse from the periphery of said rotatably mounted member, crossed wires arranged on said pins projecting, inwardly from said housing.

means for admitting fuel at two different points into the chamber within the housing, and said housing being provided with a fue outlet opening.

3. In a fuel saver for internal combustion engines, ahousing, a member arrangedfor rotation therein, pins projecting radially from: the periphery of said rotatably mounted member, crossed wires. arranged on said pins projecting inwardlyfromv said housing, means for admitting fuel at two different pointsinto the chamber within the housing. saidhousingbeing provided with a fuel outlet opening, and a sediment trap depending from the lower portion of s aid housing.

In testimony whereof I have signed "my name'to thisspecification.
