Application filed April 17, 1924. Serial No. 707,272.

To all whom it may concern:

Be it known that I, JOHN H. MoCLnL- LAND, a citizen of the United States, residing at Forestville, in the county of Hartford and State of Connecticut, have invented a new and useful Improvement in Washing Machines, of which the following is a specification.

This invention relates to the type of wash ing machines designed tobe placed in a household boiler in which clothes and similar articles are to be laundered.

The object of the invention is to provide a simple, cheap, portable apparatus which when placed in a wash boiler and the water therein is boiled will automatically cause jets of hot water and soap or other cleaning substance to be forcibly directed upon the articles being washed in such manner that they will be more thoroughly cleaned than if merely boiled.

This object is attained by forming channels in the under side of a supporting base and connecting these channels with a tubular upright that has nozzles which extend outward and terminate in downward and backward openings or mouths. The channels in the under side of the base are of such shape that when the device is set upon the bottom inside of a boiler placed on a stove or gas heater, the heat which arises from the combustion of the fuel beneath the boiler, transforms the water in the channels into steam or vapor, the pressure of which is such as to cause an upfiow of steam and hot water through the vertical tube and out through the horizontal nozzles. The force of this flow causes a strong circulation of the cleansing liquid and the nozzles project it downward onto the clothing or other articles being washed with sufiicient power to more or less agitate the articles, which particularly when taken in connection with the agitation incident to the general boiling of the mass of clothing causes the water to drive through ordinary material and thus effect a thorough cleaning.

In the accompanying drawings Fig. 1 shows a plan of the device. Fig. 2 shows a side elevation with the lower portion of the upright and the base cut in section. Fig. 3 shows a bottom view of the base. Fig. 4 shows a side view of the lower portion of the device.

The base 1 of the device illustrated is circular, although it may be of other shape if desired, and it is made of brass or other metal suitably plated to prevent corrosion. The base is of such weight that the device will not become upset when in use. 'llhrough the center of the base is a perforation in which the lower end of an upright tube 2 is fastened. The bottom of the tube does not reach to the under surface of the base in order to leave a central'recess 3 that communicates with the opening in the tube. At the top of the upright tube are two horizontally extending nozzles 4 the outer ends of which are curved oppositely and down wardly so as to discharge whatever liquid is forced through them obliquely with relation to the axis of the upright and also to the plane of the base.

In the bottom of the base are two tapering channels 5. These channels curve from the periphery of the base to the central recess and they are much wider at their outer ends than where they open to the central recess. The inner ends of these channels point to the opening at the lower end of the upright tube and on account of being restricted, pressure which is generated in the central recess tends to escape through the upright tube and nozzles rather than back through the channels.

It is desirable to form in the bottom of the base two channels 6 that extend outward from the central recess to openings in which the lower ends of two pressure stabilizing chambers 7 are fastened.

In use when the heat under the boiler becomes sufficient the water in the central recess and channels becomes converted into steam and the steam escapes upward through the vertical tube and out through the nozzles, carrying more or less of the cleaning liquid with it. Owing to the restricted orifices of the intake channels the pressure generated does not drive the water back out of the channels but carries it upward causing a rapid circulation. When the chambers are provided the pressure of the steam is stabilized so that the outflow of steam and water through the nozzles is substantially steady.

The invention claimed is A washing machine comprising a heavy base having in its lower face a central circus lar recess, uniformly tapering intake channels in the bottom face of said base, said channels curving from the periphery to the central recess with Which they communicate With restricted orifices, and channels in the bottom face of the base leading transversely outward from the central recess, equalizing chambers above the base and communicating with the outer ends of the latter channels, an upright tube communicating With the ;-hannel recess, and nozzles extending oppositely outward and curved downward from the top of said tube.

JOHN H. MCCLELLAND.
