Washers, of which the following is a specification.

This invention relates to an improvement in apparatus for washing dishes, and particularly to one Wherein hot water is employed in fine jets to remove from the dishes all ex traneous matter.

The object of the invention is to construct an apparatus for the above purpose which will wash thoronghl ya large numberof dishes in a minimum space of time and which through the medium'of hot water alone will not only wash them, but will efiect the perfect drying thereof.

With this objectin View the invention consists in the construction, combination, and arrangement of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, which form a part of this specification, Figure 1 represents in sectional elevation my improved dish-Washer; and Fig. 2 'represents a horizontal section thereof, taken in the plane indicated by the line 2 2, Fig. 1.

be made of any suitable material-:for instance, sheet iron or copper.

- Within the casing 3, and preferably at the middle of the ends, there are stand-

pipes

5 and 6, from which extend headers 7 at intervals and between which headers extend horizontal perforated pipes 8. These horizontal perforated pipes form shelves for the reception of trays holding the dishes to be washed. The hot water may be conveyed to these stand-pipes in any suitable Way, preferably by pipes, as 9 10, which lead to the stand-pipes 5 6, respectively, from a tank, as 11, which for convenience maybe located on top of the casing 3, the water being led into the tank 11 from any suitable boiler, as by means of the pipe 12. By this ari-angethe water fiows to the sewer through outlet pipe 14:. The flow of water to the tank or reservoir 11 is controlled by the cut-Q 15, and the flow of water from the tank through

pipes

9 and 10 is controlled by the cut-oft's 16 and 17.

It is often desirable to wash a small number of dishes and not to use the entire apparatus for so doing. This I accomplish by dii viding the stand-

pipes

5 and 6 vertically, as

by cut-offs 18 and 19, which is a convenient plan of subdivision, though any other plan may be followed to accomplish the purpose.

In using the apparatus the trays or racks of dishes are deposited on the shelves formed by the perforated pipes 8, the door closed, and the' water turned on by opening the cut-off 15. Then if it is desired to use the entire apparatus the cut-ofis 16 and 17 are opened, when from the perforations of the pipes 8 of all the shelves there will be projected fine streams of water, and these striking the dishes wash them thoroughly. In thus Washin g them they are heated sufficiently to insure the speedy e'vaporation of all drops of water that may cling to them after the washing is completed. The apparatus full of very dirty dishes can be thoroughly cleaned in two minutes. The cut-offs 18 and 19 are also preferably open when the entire apparatus is in use, since thereby an even pressure and flow of water is maintained in both sets of headers, and therefore at both ends of and throughout the pipes 8. r

To use the upper or lower part of the apparatus alone, the cut-offslS and 19 will be closed and the cut-oif 16 or 17 used, as the case may be. The water and dirt from the dishes are readily discharged through the pipe 14, which preferably leads to the sewer through the usual trap.

The trays for the dishes are preferahly ICO built as open as possible to aord the most complete access of the streams of water to the dishes, and the perforatious in the pipes S are as small as Will permit the flow of solid streams and are so close that the water of adjacent streams When they strike the dishes will coalesce, thereby insuring the thorough and forcihle drenching of the entire surface of each dish. Said perforations are also preferably arranged in spirals about the tuhes 8, as indcated in Fig. 2, though they may be arranged in circles, if dcsired, as indicated in Fig. 1.

Many changes may be made in the construction and formation of parts aside from those mentioned without departing from the inventiou.

I claim as my invention- 1. In a dish-Washer, the combination with a closed chamher of a stand-pipe in each end thereof, headers hranching from each standpipe, a number of horizontal perforated pipes extending from one header at one end to the corresponding header at the other end and formingshelves for dish-trays, and means for controlling the flow of water to each standpipe and into and through the perforated pipes from each end.

2. In a dish-Washer the combination with a closed chamber of a stand-pipe in each end thereof, headers branching from each standpipe, a number of horizontal perforated pipes extending from one header at one end to the corresponding header at the other end and forming shelves for dish-trays, a pipe leading from a suitable source of hot-water supply to each header, and cut-olfs in said supply-pipes and cut-olfs in the stand-pipes, as and for the purpose set forth.

3. In a dish washer the combination with a closed chamber of a standpipe in each end thereof, headers branching from each standpipe, horizontal perforated pipes extending from one header at one end to the corresponding header at the other end and forming shelves for dish-trays, a pressure-tank, apipe leading from a source of hot-water supply to said tank, pipes leading from the tank to each of said stand-pipes and cut-ofls in said pipes for controlling the flow of water through the perforated pipes.

4. In a dish-Washer the combination with a closed chamber of a standpipe in each end thereof, headers branchng from each standpipe, horizontal perforated pipes extending from one header at one end tothe corresponding header at the other end and forming shelves for dish-trays, a cut-off in the middle of each header, a hot-water-supply pipe connected to one header below the cnt-ofi therein, and another hot-water-supply pipe connected to the other header above the cut-off therein, as and for the purpose set forth.

5. An apparatus for the purpose specified conprising a casing having a fluid outlet therein, a source of fiuid-supply, a rack arranged within said casing having perforated shelves, and com minicating with the source of fiuid-supply, and valve mechanism for supplying fluid to a part of said perforated shelves, substantially as specified.
