Claims.
This invention relates to an apparatus for steam-cleaning and liquid-cleaning internal combustion engine cooling systems, and has for an object to provide a simple effective apparatus which will more effectively clean such cooling systems and in a shorter time. It is also an object to provide such an apparatus with simple controlling means.
It is a particular object to provide an apparatus in which short blasts of compressed air may be fed to the cleaning mixture of steam and cleaning compound as it flows through the cooling system to give an impulse or blow efiect to more eiiectively loosen and remove the rust and scale.
It is also an object to provide such an apparatus which may be effectively used in automobile repair garages.
With the foregoing and other objects in view, I have devised the construction illustrated in the accompanying drawing forming a part of this specification. It is, however, to be understood the invention is not limited to the specific details of construction and arrangement shown, but may embody various changes and modifications within the scope of the invention.
In this drawing:
Fig. 1 is a side elevation showing the apparatus and its use with parts broken away to more clearly show the construction, the drawing being somewhat diagrammatical;
Fig. 2 is a top plan view of a portion of the device showing its application to the cleaning of a cooling system, with a V-type engine, and
Fig. 3 is a detail view of a control for the air 1 supply valve.
The apparatus comprises what is known on the market as a steam cleaner, which is indicated at H), merely the outline being shown as such apparatus is of itself old and can be bought on the market. It comprises a cabinet or housing enclosing means for supplying a mixture of cleaning compound and water in certain proportions to a boiler or suitable heating means for heating this mixture to generate steam, and then a discharge means for discharging this mixture of steam and cleaning compound into the system of the internal combustion motor to be cleaned. While this method of cleaning internal combustion engine cooling systems has been largely used, I have found that it is much more effective if there is fed to the mixture of steam and cleaning compound as it is conducted to the cooling system, short blasts of compressed air which will give an impulse or hammer effect to this cleaning mixture as it flows through the system. These short blasts or jabs of air may be used continuously during the cleaning operation if desired, but it has been found to be sufiicient if they are supplied intermittently and in short in- 60 tervals during the cleaning operation. This impulse or hammer efiect of these short jabs or blasts of air make the cleaning mixture much more effective in loosening or detaching the rust and scale and removing it from the system. For carrying out this new method I have applied to the steam cleaner, any suitable type of which is indicated by the numeral iii, a new and effective means not only for controlling the operation of this cleaner in supplying the mixture of steam and cleaning compound to the cooling system, but also a simple and efiective means of supplying to this mixture the short blasts of compressed air and for controlling them.
Water is supplied to the steam cleaner In from any suitable source, such as a faucet I I, through a conduit l2 which is usually a flexible hose, so that the device is portable and may be used at different locations about the garage. This is connected to the device through the fixture I3 which leads by pipes or conduits (not shown) to the means for mixing the cleaning compound with the water, conducting it to the boiler or heating means from which the mixture of steam and cleaning compound, or mixture of steam, water and cleaning compound, is discharged through the conduit it. On one side wall of the cabinet of the steam cleaner i0 is mounted a control device including the pipe US to which the conduit I 4 for the mixture of steam and cleaning compound is connected, through a nonreturn or check valve 6 to a three-way valve ll. A similar pipe i8 is connected through the check valve l9 by means of the pipe connection 20 to the fixture l3 and therefore the water supply conduit l 2. The outlet 2! from the control valve ii is connected to a T fixture 22 and this is connected by an outlet 23 to a control valve 24, which in the preferred set up is a three-Way valve with two branch or outlet pipes 25 and 26, each having a fixture 27 to which may be connected a flexible hose 28 forming a conduit for conducting and supplying the cleaning mixture of steam and cleaning compound to the cooling system of the internal combustion engine to be cleaned. Such an engine is indicated diagrammatically at 29 with the cooling radiator indicated at 30 connected to the water jackets of the engine at the lower part 3!. The usual hose connection from the top of the water jacket to the top of the radiator is indicated at 32, but in use during the cleaning operation it is disconnected from the nipple 33 at the top of the radiator and is connected to the hose 28 by a connector 34 inserted into the hose 32 and held by the clamp 35. A discharge hose 3% is connected to the nipple 33 of the radiator and led to a position under the car or to a sewer drain to prevent cleaning mixture splashing onto the engine during the cleaning operation.
Connected to one side of the fitting 22 by a cleaned while connections are bein made from the other side to the other engine. Then after the first engine is cleaned the valve may be swung to out 01f cleaning action from this engine and direct it to the other engine. When valve 2-4 is in the intermediate position shown, both pipes 25 and 26 are shut off. When swung to the left, discharge 23 is open to pipe 25 and 26 is still shut off. When the valve is swung to the right, 23 is in communication with pipe 25 while 25 is shut off.
With this method and apparatus the cooling system of any car, including the engine, the radiator and water jackets, as well as the heater if there is one, can be thoroughly steam-cleaned in an hour or less.
Having thus set forth the nature of my invention, I claim:
