Y 1,491,202 F. A. EARLY CLEANING TOOL Filed 001;. '7, 1921 I JY/LZZIZJ Patented Apr. 22, 1924.



Application filed October 7, 1921. Serial No. 506,103.

To all whom it may concern:

Be it known that I,-Fnnn ALVIN EARLY,'a citizen of the United States, residing at Hays, in the county of Ellis and State of Kansas, have invented a new and useful Cleaning Tool, of which the following is a specification.

This invention relates to a tool for use in cleaning gasoline engines, transmissions and other structures in which grease is likely to accumulate.

It is an object of the invention to provide a simple, compact and eflicient tool into which air and a cleaning fluid such as gasoline, can be directed, the air being delivered through the tool under pressure so as to create a suction for drawing the gasoline or other cleaning fluid from a container and directing it against the object to be cleaned, thus to loosen the grease so that the air under pressure will drive the loosened substances away from the surfaces to which they have been adhering.

\Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in th precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In saiddrawings Figure 1 is a side elevation of the tool.

Figure 2 is a view partly in. side elevation and partly in section.

Referring to the figures by characters of reference 1 designates a tubular nozzle provided, near one end, with a valve 2 whereby gasoline or other cleansing fluid supplied to this tubular nozzle from a tank or the like, can be controlled. A handle indicated at 3 is brazed or otherwise connected to the tubular nozzle 1 and extends at an angle therefrom. Extending through this handle is an air supply pipe 4 which projects into the tubular nozzle 1. and extends longitudinally therein toward the outlet end 5, the said pipe 4 being spaced from the walls of the nozzle and terminatin inwardly from. the outlet end of the nozz e as shown in Fi re 2. A valve 6 is mounted in that! port on of the pipe 4 which projects from the end of the handle so that air supplied to the pipe under pressure from a suitable container can be controlled by the valve.

In using this tool a flexible tube or the like is attached to the tubular nozzle 1 at the inlet end 7 thereof, this tube extending from a suitable container holding gasoline. or other cleansing fluid. A flexible tube is also attached to the inlet and 8 of the pipe 4, this flexible tube being connected to a container holding air under pressure. When it is desired to clean a surface the valve 2 is opened and the valve- 6 is also opened. Thus a jet of air under pressure will be discharged toward the outlet 5 of the nozzle 1 from the pipe 4 and will create a suction sufficient to draw the cleansing fluid into the tubular nozzl 1. This fluid will be carried outwardly by the air and directed against the surface to be cleaned. The fluid will tend to soften the grease adheringto the surface and the air under pressure, by blowing against said surface will drive the loosened substances therefrom and leave the surface clean. Thus it will be seen that the tool will be especially useful in cleaning gasoline engines, transmissions, and other structures where grease is liable to accumulate.

What is claimed is I A tool for cleaning machinery, including a straight relatively long tubular nozzle having a fluid outlet at one end and a fluid inlet at its other end, said nozzle being of uniform internal diameter from the inlet to the outlet, a fluid controlling valve in the inlet portion of the nozzle, a handle extending at an angle from the nozzle between the valve and outlet but close to the valve, a pipe extending through the handle and longitudinally within the nozzle to a point back from the outlet thereof, said pipe being concentric with that portion of the nozzle in which it is located and being spaced therefrom to provide an annular fluid passage within the nozzle, said pipe constituting means for directing air under pressure longitudinally from the nozzle to suck fluid through and deliver it from the nozzle, and a valve within the pi e adjacent the handle.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
