Gasoline and Compressed Air for Cleaning By J. E. N. IT is a common practice in automobile shops to lise gasoline and compressed air to clean the dirt from otherwise inaccessible parts of an automobile, the apparatus employed requires a specially made nozzle connected with a double line of hose. The apparatus illustrated in the accompanying engraving, which was made by a friend of the writer, accomplishes practically the same result in a simpler manner. It cansists of a galvanized tank E provided with a tube, soldered into it at the top, and another one at the bottom. These tubes are fitted with valves shown at C and H. The tubes are joined and are connected by means of a %·inch hose B of any suitable length, say twenty feet, to a nozzle A. The nozzle should be provided with a quarter·inch aperture and a flared outlet. A bicycle pump D is connected with the tank Gasoline and air tank for cleaning automobiles. at one side and a pressure gage G is secured to the top. In use, a gallon of gasoline is poured into the tank, as indicated at F, and then the pump is operated to produce a pressure of several pounds in the tank. The valves C and H may now be opened to such an extent as to permit a small quantity of gasoline and a comparatively large quantity of air to fow though the hose and the nozzle A may be dl· rected to spray the parts which need cleaning. A Single gallon of gasoline and a few strokes of the air pump have been found sufficient to clean thoroughly a single automobile. This type of apparatus cannot compete in efficiency with that used in automobile shops, but it is a practical device for a private garage.
