SPRAYING APPARATUS FOR AUTOMOBILES.

Application filed February 6, 19231 Serial No. 817,137.

To all whom it may concern:

Be it known that'I, WILLIAM J. GATES, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Spraying Apparatus for Automobiles, of which the following is a specification. V

This invention relates to a device for m spraying a solvent oil, such as kerosene or distillate with air pressure, on such parts of an automobile as are coated with oil, grease, road oil, tar, etc, that these substances may be softened to such an extent that they may be washed off with soap and water.

I prefer, however, to allow said oil to remam on automobile for several minutes before washing off, as e washing may then go be accomplished .wit a lower water ressure and without rubbing which ten s to mar the finish.

This device quickly and conveniently applies this oil coating, and as both the oil and go the mixture of oil and air are at all times under complete control of the operator, the amount of oil used on each automobile is very small.

A further object of the present invention go is the provision of a novel form of control valves, which ermits the operator to manipulate this evice by the movement of a single lever.

Another object is to provide an arrange- -ment whereby the pressure tank is automatically filled from the storage tank and provides the necessary oil for spraying an automobile without attention or efiort on' Figure 1 is a side elevation of the complete spraying device; and

Figure 2 is a side elevation of the spray B6 tip and valve.'

Referring to the drawings, the numeral 1 designates a tank which forms a reservoir or receptacle for storing a solvent oil, the lower extremity of which receives the threaded pipe 2, which connects with valve cock 3, upon the opening of which valve the oil flows by gravity through pipe 2, valve 3, and T fitting 4 into pressure tank 5.

The level of oil in this tank is visible 05 through gauge glass, 6, which may be protected from breakage by pressure, by closing of valves 7 and 7.

An air pipe 11 conveys air under pres sure from air storage tank 13 to valve cook 10. This storage tank may be located at any convenient position suitable for installing said tank and air compressor. Upon the opening of valve 10 by lever23, valve 3 is automatically closed by means of connecting bar 12, the closing of which prevents air from entering oil reservoir 1. The air passes through valve 10,through pipe 14 to T fitting 9 where the air divides and passes through pipes 15 and 16. The air so which passes through pipe 16 enters pressure tank 5 through T fitting 4 and increases the oil pressure to that of the air. This permits the oil to flow through valve cock 8, through needle valve 22 to T fitting 17 8| where said oil unites with the air passing through pipe 15, from which the oil and air mixture flows through flexible tubing 18 to spray tip 26 shown in Figure 2. i The proportion of oil to that of air in this mixture is regulated by adjusting needle valve 22. Upon the closing of valve 10 and valve 8, the oil valve 3 is automatically opened permitting oil from reservoir 1 to flow by gravity into pressure tank 5, thus filling tlllS tank for a repetition of operations.

To prevent this tank from overflowing and filling the air conveying pipes, a check valve 21 is provided, which permits air to pass into T fitting 4, but closes when oil has completely filled tank 5.

It will be noted that the valve cock 3 is operated by means of a lever having a air of arms 24 and 25. Arm 24 is operated by a horizontally disposed connecting bar 12 operated by hand lever 23, which is fulcrumed on plug. of valve cock 10. The arm 25 is connected with valve lever 20 by means of a vertically disposed connecting bar 19. This arrangement permits the operation of valve cocks 10, 3, and 8 simultaneously, valves 10 and 8 being open when valve 3 is closed and valve 3 open when valves 10 and 8 are closed. I

From the foregoing description and a.

study of the drawing it will be apparent that I have thus provided a very simple and eliicient device for spraying an oil on automobiles for dissolving the oil and grease on same.

Having thus described this invention I hereby reserve the benefit of all changes in form, arrangement, order, or use of parts, as

it is evident that many minor changes may be made therein without departing from the spirit of this invention or the scope oi the following claims.

. I claim:

2. A spraying apparatus comprising a reservoir, a pressure tank, a pipe from the reservoir to the pressure tank, a valve in said pipe, a spraying device, a pipe from the pressure tank to the spraying device, a valve 111 said second pipe, a pressure storage tank arpipe from the pressure storage tank opening into said first pipe between said first valve and said pressure tank and opening into said second pipe between said sec-.

ond valve and the spraying device, a valve in said third pipe, and mechanism for operating said three valves simultaneously to open said second two valves and to close said first valve, and vice versa, a check valve in said third pipe between said third valve and said first pipe, and a needle valve in said second pipe between said second valve and the connection of said second pipe with said third pipe.
