DISHWASHING APPARATUS.

Original 110. 1,330,734, dated Augiut 9, 1921, Serial No. 418,887, filed October 23, 1920. Application for reluue filed January 28, 1922. Serial No. 532,510.

To allwlwmit may concern."

Be it known that I, HARRY ROSENBAUM, citizen of the United States, residing at New York, in the county of New York and State I of New York, have invented new and useful Improvements in Dishwashing Apparatus,

of which the following is a specification.

This invention relates to apparatus for washing dishes, and more particularly one inwhichthe dishes'are placed in a closed stationary receptacle and subjected to the cleansing action of a plurality of streams of water sprayedover the same.

The invention has for its object to provide- Referring specifically to the drawing, 5

:0 denotes a water-tight receptacle of any suitable contour and dimension, in which the dishes to be washed are placed, access to the receptacle being had by having the same open at the top. A tight fitting hinged door 6 is provided for the top of the receptacle, and in the receptacle are mounted suitable racks 7 which support the dishes shown at 8.

Passing centrally through the receptacle 5 is a rotatable spray pipe 9 which is providedwith a large number of perforations 10 through with the water is discharged. One

end of the pipe 9 is closed and this end is supported in a bearing 11 mounted on the corresponding end wall of the receptacle 5. The other end of the pipe 5 is open and is supported in a bearing 12' mounted on the corresponding end wall of the receptacle. Thev bearing 12 has a nipple 13 which passes through the end wall ofthe receptacle, and on the outside of the receptacle there is coupled to the nipple a water supply hose 14 obtaining hot water from any suitable source. The bore of the nipple 13 is in communica: tion with the. open end of the pipe 9, and hence, when the water is turned on, it flows longitudinal section i into said pipe and is sprayed through perforations 10 thereof over the dishes 8.

One end. of the pipe 9 is fitted with two diametrically'opposite, and radially extending discharge tubes 15 from which the water is discharged at their outer ends, said ends being bent laterally to obtain a tangential discharge. The reaction of the water discharged froln theftub'es 15 at the outer endsthereof causes said arms to revolve and thus rotate the pipe 9, with the result that the water discharging from the perforations 10 is continually sprayed over the dishes 8, and the latter are rapidly and thoroughly cleansed. The receptacle is provided with a drain 16.

The apparatus is very simple and efficient, and it is well adapted for domestic use as it can be operated by connecting the hose 14 .to the hot water faucet in the kitchen. The

apparatus is also economical in operation as the amount of water it requires is not greater than that ordinarily used when washing and rinsing dishes by hand.

I claim:

1. A dish washer comprising, in combina tion, a dish receptacle, a spray device mounted to rotate upon a horizontal axis within said receptacle and adapted to direct the spray in directions generally transverse to said axis, said spra device being provided with reaction jets or continuous complete rotation of the same whereby the spray is caused to sweep in continuous complete circles about the axis of rotation of said spraydevice, and a liquid supply connection for said spray device. 1

2. A dish washer comprising, 'in combina-- tion, a walled dish receptacle, a spray device extending horizontally between and rotatably supported by opposite walls of said receptacle, said spra' device being provided with reaction jets or continuous complete rotation of the same whereby said spray is caused to sweep in continuous complete circles about said axis, and a liquid supply connection for said spray device.

3. .A dish washer comprising, in combination, a dish receptacle, a. spray device mounted to rotate upon a'horizontal axis .within said receptacle and adapted to direct the spray in directions generally transverse to said axis. said spray device being provided with reaction jets for continuous complete rotation of the same whereby said spray is caused to sweep in continuous complete circles about said axis, a liquid supply connection for said spray device and dishsupportingmeans arranged in said receptacle about said spray device.

4. A dish washer comprising, in combination, a walled receptacle, a centrally located spray device supported by opposite walls of said receptacle to rotate upon a horizontal axis within the same, said spray device being provided with reaction jets for continuous complete rotation of the same whereby the spray is caused to sweep in continuous complete circles about said axis, a liquid supply connection for said spray device and dish-supporting means arranged above and below said spray device.

5. A washing apparatus comprising a re ceptacle, a perforated spray pipe mounted to extend horizontally of the receptacle and to rotate upon its axis said spray pipe being provided with reaction jets for continuous complete rotation of the same whereby the spray device is caused to sweep in continuous complete circles about said axis, and

dish supporting means arranged to support dishes about said spray pipe.

6. A washing,apparatus comprising a receptable, a perforated spray pipe extending horizontally and centrally between the opposite end wallsmf the receptacle and rotatably same.

In testimony whereof I afiix my signature.
