Application November 23, 1940, Serial No. 366,907

1 Claim.

The present invention relates to a device for cleaning air filters, wheel-bearings, tools and other small parts of machinery, such as for automobiles, and has for its primary object to provide a container within which the part to be cleaned is placed and providing means for blowing a mixture of air and cleaning fluid against the parts to be cleaned to remove grease, dirt and other foreign substances therefrom, the invention further embodying a suction fan adjacent the top of the container for drawing off the fumes and vapor of the cleaning fluid for discharging the same to the outside of the building.

A still further object is to provide a device of this character of simple and practical construction, which is efficient and reliable in performance, relatively inexpensive to manufacture and maintain in operation and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in Which- Figure 1 is a side elevational view,

Figure 2 is a top plan view.

Figure 3 is a vertical sectional view, and

Figure 4 is a transverse sectional view taken substantially on a line 4--4 of Figure 3.

Referring to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates an open container within which a screen 6 is supported on a rack 'l immediately above the level of a cleaning liquid 8, which preferably is in the form of kerosene.

Extending through a wall of the container 5 is an air nipple 9 to the inner end of which is attached a nozzle l and connected to the nozzle is a downwardly extending pipe Il which terminates in the cleaning liquid 8. To the outer end of the nipple 9 is attached an air hose l2 leading to a suitable source of air pressure.

Accordingly, the air filter, wheel-bearing or other object to be cleaned may be placed in the container immediately above the screen 6 and by admitting air under pressure through the nipple 9 the cleaning liquid will be drawn upwardly into the pipe Il and discharged with the air through the nozzle l0 against the part to be cleaned.

The top of the container 5 is partly closed by a shelf I3 preferably positioned at the side of the container opposite from the nipple 9 and supported on the shelf is a bracket I4 to which an electric motor l5 is connected with the shaft I6 of the motor projecting downwardly into the container and into a fan housing I'l wherein a suction fan I8 is mounted on the lower end of the shaft of the motor. The bottom of the housing Il is provided with a screen I9 whereby vapor and air from the interior of the container may be drawn upwardly into the housing for discharge through a conduit 20 attached to the housing l1 for conveying the vapor to the exterior of the building.

Extending downwardly from the inner edge of the shelf I5 is a shield 2l to the under side of which is secured a bracket 22 for supporting an electric lamp 23 thereon by means of which the interior of the container 5 may be illuminated.

It is ybelieved the details of construction, operation and advantages of the device will be readily understood from the foregoing without further detailed explanation.

Having thus described the invention, what I claim is:

A cleaning apparatus comprising a container adapted to contain a quantity of cleaning fluid, an air nozzle supported in a horizontal position at one side of the container above the level of the liquid therein, a pipe connected to the nozzle leading to the fluid, an air hose attached to said nozzle for feeding air under pressure to the nozzle and adapted to draw the liquid upwardly into the pipe Iby the action of suction from air passing through the nozzle, a reticulated support in the container above the level of the liquid therein and adapted for supporting articles to be cleaned in the path of the fluid discharged from the nozzle, and a splash shield partly closing the container and projecting inwardly from a wall thereof at a side of the container opposite from the nozzle and overlying the articles being cleaned to trap spray and vapor in the container.
