PATENT OFFICE LEO nnu'rscn, or BEAVER, rnnnsxnvama -.APPA.RATU S FOR CLEANING CONTAINERS Application filed September 2, 1927. Serial No. 217,023.-

This invention relates to an apparatus for cleaning containers and the like, and more particularly to a motor vehicle service station unit for cleaning gear casings and the like.

One object of the invention is to provide such an apparatus which shall be very simple in its construction and operation, which will comprise but a few parts, and which will require but little attention to maintain the same w in operative condition.

A further object of the'invention is provide in such an apparatus an ejector havin means for increasing the efiiciency thereo A further object of the invention is to providesu'ch an apparatus so constructed thatthe greasy fiuid withdrawn from the gear casing and discharged into the container will not foam to an objectionable extent.

A further object of the invention is to prowide in such an apparatus improved means for supporting the pump within the container.

A further object of the invention is to provide in such an apparatus improved means.

for keeping the strainer clean.

Other objects of the invention will appear as the apparatus is described in detail.

In the accompanying drawings Fig. 1 is a side elevation, partly in section, of an apparatus embodying my invention; Fig. 2 is a section taken vertically through the pump andthe inlet casing, Fig. 3 is a front elevation of the upperportion of the apparatus showing the ejector; and Fig. 4 is .a transverse section taken on the line 44 of Flg. 1.

' In these drawings I have illustrated one embodiment of my invention, but it will be understood that-the particular embodiment here shown has been chosen for the purposes of illustration only and thatthe various parts of the apparatus may take different forms and may be arranged in difi'erent ways with- 1 outdeparting from the spirit of the invention.

In that form here illustrated the apparatus comprises a container 5 for cleaning fluid, such for example, as=kerosene, and which is preferably .cylindricalin form and the top wall'6 of which is removable and constitutes a closure and also a support for various parts of the mechanism. Mounted on the container 5 is a pump which in the present instance is supfported within the container from the top 0 wall 6' thereof and which is preferably a rotary pump, as shown at 7.

The intake of the pump is immersed in the fluid within the container, and the discharge 'pipe 8 leads from the pump through the top wall 6 and is connected .with a pressure line which is preferably in the form of a flexible conduit or hose 9 adapted to have its discharge end inserted in the casing to be cleaned. If desired, the discharge end of the conduit may be provided with a nozzle 10 having a manually controlled valve 11 to control the-discharge of the fluid therefrom. A suction conduit is connected with the container and is adapted to have its intake end inserted in the casing to be cleaned so that the cleaning fluid, grease and other matter within the casing may be withdrawn therefrom and delivered to the container. This suctionline is here shown as comprising a flexible conduit or hose 12 which, if desired,

. maybe provided at its intake end with a nozzle 13 having a manualy controlled valve 14.

Connected with this suction conduit 12 and the pump that this jet will substantially fill 9 the bore of the ejector, and in the device here shown this means comprises a pin 16 extending through the ejector in the path of the jet of fluid.

Because of the considerable quantities of grease contained in the fluid which is discharged into the container 5'this fluid has a tendency when agitated to foam to an extent which is highly objectionable and Ir have found that by directing the incoming column of fluid from the ejector against the side wall of the container above the level of the liquid therein this foaming can be entirely avoided or reduced to such an extent that it is not objectionable. As here shown, the inner or discharge end of the ejector is provided with a curved deflector 17 so arranged that it will cause the column of fluid to be discharged from the ejector in a substantially horizontal plane a ainst the wall of the container.

and at an o tuse angle to that wall.

The pump 7 may be mounted within the container in any suitable manner, so long as its intake is submerged. In the present apparatus the pump itself is entirely submerged in the cleaning fluid and it is here shown as connected with the top wall or closure 6 by means of rods 18 and a cylindrical spacing member 19 of relatively large diameter is interposed between the pump and the top wall to maintain the pump in the proper spaced relation to the top wall. A driving shaft 20 is directly connected at its lower end to the pump 7 and extends upwardly through the spacing member 19 and the top wall 6 and is directly connected at its upper end with the shaft of an electric motor 21, the connection being preferably a separable one as shown at 22 to permit of the ready removal of the motor. By thus directly connecting the motor with the pump and eliminating the gears and other intermediate parts which would otherwise be necessary, I greatly simplify the mechanism and so reduce the number of parts therein as to materially decrease the cost of construction and to simplify the maintenance of the apparatus. This direct connection permits the motor to be mounted directly on and centrally of the top wall 6 of the container, thereby providing a very compact and convenient arrange ment. 4

The fluid which is withdrawn from the gear casing which is being cleaned contains ardened grease and other solid matter, and in order to prevent such matter from entering the pump I have provided the latter with a strainer. In that form of the mechanism here shown an inlet casing 23 is connected with the pump intake and provided with a foraminous wall or strainer 24. As here shown, this inlet casing is aranged below and directly connected with the pump. Means are also provided'to prevent the grease and other forelgn matter in the fluid from accumulating on the strainer to such an extent as to interfere with the free flow of the fluid through the same. This is accomplished by directing a stream or streams of fluid against the strainer, and in the present instance this fluid is taken from the pump independently of the ejector. To this end a second and relatively small discharge pipe 25 is connected with the discharge side of the pump and has a portion 26 extending across the strainer 24, this portion of the pipe having in each side thereof a series of small holes from which the fluid is discharged across the face of the strainer, thus preventing the grease from adhering to the strainer and washing off any matter which may come in contact with the strainer.

In the present arrangement the apparatus is shown as mounted on a truck consisting of wheels 27 and upright handles 28, whereby the apparatus may be readily transported from one place to another.

While I have shown and described one embodiment of my invention, I wish it to be understood that I do not desire to be limited to the details thereof as various modifications may occur to a person skilled in the art.
