Application All 26, 1943, Serial No. 500,110

Our invention relates to a gasoline conserving attachment particularly designed for use in connection with the gaseous fuel supply systems of motors and has for its principal object, to provide a simple, compact, inexpensive device which will to a considerable extent'convert the liquid hydrocarbon into vapor a it flows from the pump. to the carburetor and, during'such conversion, the gasoline being subjected to catalytic action so as to regroup the hydrocarbons and thereby materially increase the power development when the vaporized fuel is ignited in the combustion chambers of the engine.

Further objects of our invention are, to provide for smoother, more flexible engine operation, quicker acceleration, increased mileage of travel and absence of knock or ping, particularly 7 when lower grades of gasoline are being used.

A further object of our invention is to provide simple and efiicient means for automatically controlling the volume and level of the liquid gasoline within the vaporizing chambers of the attachment.

With the foregoing and other objects in view, our invention consists in certain novel features of construction and arrangement of parts which will be hereinafter more fully described and claimed and illustrated in the accompanying drawing in which:

Fig. l is a vertical longitudinal section taken through the center of our improved attachment.

Fig. 2 is a detail section taken on the line 2-2 ventional.

Associated with tank is the usual gasoline outlet pipe !5 having a float actuated section it within said tank, and said pipel5 leads to a pump H.

From the pump a tube28, provided with a flow control. valve 2| leads to the upper portion of the chamber in housing I8 below partition I9 and this tube is extended as designated by 26* to the exhaust manifold, So as to be heated thereby. Thus the gasoline flowing through said tube is heated so as to greatly increase the subsequent catalyzing and vaporization thereof.

The inlet end of pipe section it is connected to the float within tank i3.

The attachment contemplated by our invention includes a vertically disposed cylindrical housing it which is divided into upper and lower chainhere by an imperforate partition it.

Leading from pump ill to the upper portion oi the chamber below partition 89 is a duct 2D having a flow control valve 25. A sediment outlet opening 22, formed in the bottom of housing id, is normally closed by a cap 2%, and the chamber within said housing below partition it is filled with copper or bronze wool or shavings 2t. Cap 23 is removed only forthe purpose of cleaning dirt and sediment out of the lower chamber in the housing.

Located in the chamber in housing it above partition i9 is a screen 25, and leading from the space between partition l9 and said screen to the lower portion of a small tank 26 is a tube 2t.

Depending from tank 26 is a fitting 28 having a valve seat 29, and adapted to rest thereupon is a the lower end of a valve 30 which depends from a float 3i.

Leading from the lower portion of valve fitting 28 to tank i3 is duct 32 having an inverted U- shaped portion 33 which extends above the normal level of the gasoline in tank 25, and located in said duct between said portion 33 and the tank i3 is a flow control valve 3 3.

Surrounding the upper portion of housing 48, and spaced apart therefrom, is a shell 3%, the vertical wall of which is corrugated to provide additional air cooling surface, and the annular bottom of this shell occupies approximately the same horizontal plane with the screen 25 and just above pipe 21.

The space 31 between partition I?) and screen. 25 provides a gasoline collection chamber. The top of housing It is perforated as designatedvby 38, and extending axially downward from said perforated top is an ended tube 39 which passes through screen 25 and partition i9, and the lower end of said tube terminates just above the bottom of said housing l8.

The upper portion of this tube 39 is perforated as designated by 40, and that portion of said tube below partition is also perforated as designated by 43 Positioned on tube 39 just below the perforations 40 i a perforated gasoline distribution plate 42, and filling the space between this plate and the screen 25 is a body 43 of copper or bronze wool or shavingsl Surrounding corrugated sheet 35 is a vapor cooling and condensing coil M, the upper endof which communicates with the chamber between the top of said shell and the top of housing l8; immediately above the open upper end of tube pressure.

39 and leading from the upper end of. this coil to the to og float tank 26 is a balancing tube 46;

Leading from the lower portion of the chamber between housing It and corrugated shell 35 to the filter i2 is a duct 46 (see Fig. 2), and connecting the lower end of coil 44 with this duct is a substantially U-shaped trap 41. The wall of housing I8, just above screen 25 and the annular bottom 36 of the corrugated shell 35, is perforated During operation, pump I'I draws gasoline from the top of the liquid body in tank I3, through ducts I6 and I5 and forces said gasoline through duct 26 where it is vaporized by heat from the exhaust manifold of the motor and the resultant vapor passes into and through the body of copper or bronze wool, or shavings 24, and is thereby subjected to a certain catalytic action, thus to a considerable extent, regrouping the hydrocarbons in the gasoline, so as to greatly improve and increase the qualities thereof.

Any heated gasoline which is not entirely vaporized in tube and which enters the lower portion of housing I8, accumulates in the bottom of the chamber in said housing, and such gasoline and vapor are under from two to five pounds Thus hot gasoline when entering the carburetor, where it is under further pressure, is readily broken up into extremely fine particles, and in such condition, it is drawn into the combustion chambers under vacuum and finally ignited so a to release power units.

The vaporized gasoline after passing upward through tube 39 discharges into the open upper end of copper coil 44, and in passing downwardly therethrough, said vapor is condensed into heated gasoline and unites with any heated gasoline that may flow upward through pipe 39 and discharge into coil 44.

Any liquid gasoline discharging from tube 39, which does not enter tube 44, passes back into housing I8 through apertures 38 and any gasoline which enters chamber between housing I8 and corrugated shell 35, flows-downward through said chamber and finally enters chamber 31 after passing through apertures 48 and screen 25.

If this accumulation of gasoline in the chamber above partition I9 rises to the level of the apertures 48, then said gasoline will pass through pipe 21 into tank 26.

Any heated condensate (condensed gasoline vapor) accumulating in tank I8 above screen will flow through duct 46 to filter I2 and in so doing, it is joined by the heated condensate discharging from the lower end of coil 44' unto said duct 46.

In case there should be any vapor bubbles in this heated liquid gasoline delivered from coil 44,

said bubbles will separate from the liquid in trap 41 and rise and escape back through duct 46 into housing I8, thus effectually preventing the formation of any vapor lock.

Any liquid gasoline discharging from the upper end of tube. 39 will, 'by gravity, pass downward through perforations 38, thencethrough perforated plate 42 and thence downwardly through the body 43 of bronze or copper wool or shavings so as to be partially vaporized, and at the same time subjected to catalytic action, and said vapor '4 will rise through housing I8 and into and through coil 44.

Practically this same vaporizing and catalytic action takes place in the copper or' bronze wool or shavings-filled chamber between the upper portion of I3 and surrounding corrugated shell 35.

It is to be" noted that both'chambers' within housing I8 and the chamber between shell 35 and housing I6, are practically filled with copper wool or shavingsand thus all gasoline, either liquid or vapor form, that enters and passes through said chambers must make direct contact with the large bodies of copper wool or shavings, which contact brings abouttheo'atalytic action to efiect the regrouping or the hydrocarbons so that development of power when the fuel is ignited is greatly increased.

And liquid gasoline which may flow downwardly through the copper wool or shavingsdllled chambers will finally pass into chamber 31 betweenscreen 25 and partition I9 and when the level of thisaccumulated gasoline rises within pass therefrom tank 26, it will fiow past open valve 30 thence through duct 32 and open valve 34 back to gasoline storage tank I3.

Condensed vapor from the chamber between housing IB and corrugated wall 35 may flow through duct 46 to join the condensate flowing from the lower end of the cooling coil 44 to and through said duct to filter I2 and to the carburetor. v

If surplus gasoline collects in the chamber between screen 25 and partition I9, it will flow into the float chamber and from thence back to tank I3, and thus our improved attachment functions as a cushion between the float chamber, carburetor and pump so as to conserve gasoline consumption.

During operation a certain amount 0! gasoline will discharge from the end of tube 39 directly into coil 44 to be condensed therein, and any vapor discharging from fitting 41 will pass through duct 46 into the upper chamber within housing I6to assist in further vaporization of gasoline and vapor passing therethrough.

Under all running conditions the volume of liquid within the attachment should fill chamber 31 and rise above the screen 25 and above the bottom 36 of the shell.

Actual use of our improved attachment throughout a period of several months has proven a substantial saving of gasoline, increased mileage with lower grades of gasoline without knocks or ping, quicker acceleration and a more powerful and smoother running motor.

In our attachment, the excess gasoline which collects in the chamber above partition I9 is fed back to the gasoline tank through the automatically operating float-controlled valve, thus effecting a saving of gasoline which would otherwise be wasted."

Thus it; will be seen that we have provided a gasoline conservin power increasing, hydrocarbon motor, which is simple in structure, inexpensive of manufacture and very effective in performing the functions for which it is intended.
