GASOLINE CLARIFIER.

Application filed October 21, 1926. Serial No. 143,201.

This invention relates to gasoline clarifiers and more particularly to a device of this character adapted for use in cleansing the gasoline employed in cleaning establishments.

An important object of the invention is to provide a device of this character in which the cleaning of the gasoline is expedited and at the same time a product provided which is free from impurities of any sort.

A further object of the invention is to providea device of this character which prevents introduction of air into the cleaning tank with the gasoline. In many devices of this character, the construction is such that air enters with the gasoline, with the result that the solution is disturbed and rapid clarification of the gasoline prevented.

.A further object of the invention is to provide a device of this character wherein the'pressure applied to the gasoline injected into the casing is prevented from fluctuating rapidly, so that the contents of the container will move uniformly and the cleansin ope-ration can accordingly be very accurate y controlled.

These and other objects we attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown, a preferred embodiment of our invention and wherein Figure 1 is-a vertical sectional view of a gasoline cleaner constructed in accordance with our invention; I

Figure 2 is a section on the line 22 of Figure 1; v

Figure 3 is a section on the line 3-3 of Figure 1.

Referring nowmore particularly to the drawings, the numeral 10 indicates a casing, at present shown as rectangular in form and has its bottom in the. form of a funnel 11, the lower end of which is provided with a valve control drain opening 12. Immediately above the upper end of the funnel, the casing 10 is provided with an outlet 13, whlle at its upper. end a further outlet 14 is provided. -The top of the casing is prov ded with a removable cap 15. Extending into 9 the casing adjacent the lower end thereof is a conduit 16, the inner end of which s provided with an extension 17 co-axial with the casing and havin at its lower end a d1stributor head 18 rom; which radiate a plu-' rality of discharge nozzles 19. The outer end of the conduit 163 communicates with a vertical stack 19 of greater diameter than the conduit. The upper extremity of this stack is vented at 20 and is provided with an inlet 21 arranged below the vent and adapted for connection with the usual gasoline pump of the cleaning apparatus. Adjacent the casing 10, the conduit 16 has associated therewith -a funnel 22, the outlet 23 of which is valvecontrolled. This funnel provides a means for introducing to the funnelshaped bottom 11 of the casing 10 a commercial alkalized solution, such as is ordi narily employed in cleansing gasoline.

Arranged within the casing 10 is a rack comprising vertical supports 24, the lower ends of which rest upon the inner faces of the walls of the conical bottoms 11 adjacent the tops thereof. These racks support a plurality of horizontally extending .bafile plates 25, each of a length less thanthe width of the casing and each having one end extending close to the wall of the easing and the opposite end spaced therefrom. The spaced ends of the baflle plates 25 are al- 89 ternated, so that a circuitous path is pro- 'vided for liquid arising through the plates.

The edges of the baffle plates 25 which are spaced from the casing are each provided with downwardly bent lips 26 arranged at an acute angle to the plate and adapted to catch any floating material carried b the liquid passing between the plates. bove the channel 27 provided between the upper: most plate 25 and the wall of the casing, a further baflie plate 28 is disposed to insure proper distribution of liquids and prevent these liquids from arising in a vertically moving current which would cause all impurities carried thereby to engage against lter 29 arranged above the rack. The filter 29 is formed by providing two screens 30 and 31 of suitable mesh and of a size to fit within the walls of the casing. The screen 30 rests direct] upon the upper ends of the 100 standards 24 o the rack and upon the screen is placed a suitable filtering medium, such as cotton seed hull,,cotton batting, waste or similar material which will remove from the liquid any floating substances, such as might 105 pass-the lips 26. The screen 31 is then placed on top of this material and has its upper surface immediately below the level of the outlet 14. The stack 19' hereinbefore mentioned should have its upper end well spaced above the upper end of the container 10;

In operation, through the ity leaves Within the alkali solution, the major portion of the dirt carried thereby. As the gasoline rises through the path provided by, the baflle plates 25, floating substances will be collected by the lips 26' and removed therefrom. In its passage through the filter 29, any

other substances carried thereb will be removed. Pure gasoline is with rawn from the outlet 14: and returned to the cleaner. Dirty gasoline and muck may be removed through 'kali solution and any sediment contained therein may be drawn through the outlet 12. It is pointed its filtering material readily replaced at any time and that in cleanin the filter, it is mere- 1y necessary to remove t e cap 15, withdraw the filter and rack for cleansing and then the outlet 13 and the. al-

out that the filter 29 may have withdraw the dirty gasoline and alkali solution.

Since the construction hereinbefore setfort-h is capable of a certain range of change and modification without materially departing from the-spirit of the invention, we do not limit ourselves to such specific structure except as hereinafter claimed.

We claim v A gasoline clarifier comprising a casing having a funnel-shaped bottom wall, a filter disposed across the upper part of the casing, a conduit pipe passing through the side of the casing, and having an end extension disposed co-axial with relation to the funnelshaped wall of the casing, a distributing head located in the funnel-shaped wall of the casing and attached to the extension of said conduit, radially disposed nozzles carried by the head, a vertically disposed stack for supplying gasoline to theconduit, said stack aving its upper portion disposed above the level of the filter, and means for supplying an alkali to the conduit between the stack and the casing.

In testimony whereof we. hereunto aifix our signatures.
