DISHWASHING MACHINE Filed Agg. 30, 1929 I5 Sheets-Sheet 3 Patented Nov. ll, i930 UNITED s'rATEs iasiofz JOHN E. CATLETT, F SAN FRANCISCO, CALIFORNIA DISHWA'SHING MACHINE Application filed August 30, 1929. Serial No. 389,487.
This invention relates to a machine' for washing dishes, one of the objects being to provide a means whereby air can be forced into a cleansing fluid so as to agitate it and cause rapid and thorough cleaning of the dishes or other articles being acted on.
Another object is to utilize air as a drying medium whereby` after withdrawing cleansing fluid from the container of the machine,
air can be directed against the articles that have been washed so as to quickly dry them.
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 changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.
In the accompanying drawings the preferred form of the invention has been shown.
In said drawings, Figure 1 is an elevation of the complete machine.
Figure 2 is a section on line 2-2, Figure 1.
Figure 3 is an elevation of one form of basket that may be used in the container.
Figure 4 is a section on line 4-4, Figure 1. Figure 5 is a section through another form of basket for use in the container.
Referring to the figures by characters of reference, 1 designates a stationary drum adapted to be supported in any suitable manner, this drum constituting the stub or main container of the machine. The drum has its bottom inclined downwardly as shown at 2 to an outlet 3 opening into a drain pipe 4 and a suitable valve indicated at 5 can be used for normally closing the drain.
The container 1 is provided with a removable cover 6 which can be inclined upwardly toward its center and in the central portion 45 of this cover may be formed vent openings 7.
' A baffle plate 8 can be supported under the apertured portion of the cover and connected v to the cover so as to prevent the liquid contents of container 1 from splashing upwardly 5G through the openings 7.
container 1 is a basket 16 formed preferably I of wire woven to produce a coarse mesh.
This basket is open at the top and is formed preferably with a central conical portion 17 for holding silverware. Dishes to be washed are adapted to be placed around the central portion 17 in the basket 16. It will be noted that the bottom of the basket is supported off ofthe bottom 2 of the container 1 except close to the wall of the container.
As a further means of supportingarticles to be washed, a wire basket or tray indicated at 18 in Figure 3 can be used, this being provided with an annular inclined bottom portion 19 open at the center. This can be positioned above the basket 16.
In practice the dishes', silverware, etc., to
be washed are placed in the basket 16 and,
if desired, in the tray 18. Thereafter va cleansing fluid is placed in the container 1 so as to cover the contents. This will leave an air space above the fluid. Pump 9 is then actuated by motor 10 and will act to force air under pressure to the ports 14 from which it will be discharged upwardly through the cleansing fluid. Thus the fluid will be thoroughly agitated and will quickly and thoroughly clean the articles contained in the machine. As the air is released from the cleansing fluid it will pass into the surrounding atmosphere through the pipe 15.
After agitation has taken place for a desired length of time the valve 5 is opened and the cleansing fluid permitted to drain from container 1 The air can then again be forced through the container and, by blowing across the Washed articles, will remove moisture from them so that they will be dried quickly.
What is claimed is:
In a machine for washing dishes or the like i the combination with a container having vent openings, of a valved drain extending downwardly from the bottom of the container, said bottom being flared upwardly from the drain, an air pump, means for actuating the pump, widely spaced ports extending through the bottom ofthe container at points remote from the drain, air pipes extending upwardly to the respective ports and connected to the air pump, said pipes and ports cooperating to direct widely-spaced, relatively-large jets of air upwardly into the container to throw the liquid contents of the container onto the dishes or the like in the container.
In testimony that I claim the foregoing as my own, I have hereto axed my signature. JOHN E. CATLETT.
