To all 'whom 'it may concem:

Be it known thatLHAnmroN F. Low, a citizen of the United States, residing at the borough of Manhattan, city, county,and State of New York, have invented new and useful Improvements 'in Dish-Washing Apparatus, 'of which the following is a specification. This invention relates todish washing apparatus, and has for its object to provide improved apparatus of this character which will be superior in point of eciency, durability andeconomy, and safety in operation.

The invention has for its particular object the provision of apparatus of the character described, whereby the cleansing water may be caused to execute a highly eiicient to and fro movement above and throughoutl the pile or load of dishes to be washed, at the same time in Lthe main being directed downwardly upon the ,dishes so as to prevent disarrangement of the same, with the attendant breakage or fracture,` during the washing operation.

In the drawings: Figure l is a front elevation of a dish washing apparatus constructed according to the invention; Fig. 2 is an enlarged vertical transverse sectional View of tank 1, taken upon the line a-a, Fig.v 1, and looking in the direction of the appended arrow; Fig. 3 is .a substantially horizontal transverse sectional view of the same, taken upon the lines b-b, Fig. 2, looking in the direction of the appended arrow; and, Fig. 4 is a per- O spective view of a diffusion element constituting an essential part of the invention. vCorresponding parts in all the figures are denoted by the same reference characters. Referring'with particularity to the drawings, thevinvention is illustrated aslbeing comprised within two as sembled casings or tanks, 1 and 2, used respectively for washing and rinsing. While Ibut one of the Washing tanks 1 is shown, a number ofthe same may be employed, said tanks being arranged in a battery, and being duplicates in formation and provision of operative parts, and being used', in practice, for the initial washing operation. Without reference to the number of the :tanks 1, but one of the rinsing tanks 2 is required for the 4final rinsing operation.

Each of the tanks, 1 and-2, is provided at its lower forward portion with an inlet header 3, and connected with both of said headers is a steam supply pipe, 4 and a water supply pipe 5, cocks 6 and 7respectively being installed between the steam supply pipe 4 and the headers 3 and between the water supply pipe 5 and the headers 3.

` Each of the tanks 1 and Z is provided at its upper forward portion with an overflow header 8, which headers are connected by an overflow pipe 9, which is extended downwardly, as at 10, and horizontally beneath the tanks, to form a discharge pipell, communicating with discharge lpipes 12, one of which connects with the bottom portion of each of the tanks.

pipes 12 is controlled, in its communication -with the The bottom of each of the tanks with a bottom 14 which includes a screened orifice 15 communicating with the respective discharge pipe 12. Each ofthe tanks 1 and 2 is preferably four-sided, .and

each of the corners of the same, at the bottom of then tank, is separately clit on by two upright partitions 16 which approach .each otherinwardly atan acute angle and are but slightly spacedapart at their adjacent outer edges. Each/couple of these partitions 16 forms, inthe respective corner 16, a pocket into which the water in land 2 is provided.

the tank flows in its circulation-through the tank. I testing upon the several pairs of partitions'l, is a grating or perforated detachable partition 17 which extends across the tank but slightly-above tho bottom '14 thereof, the v grating 17 being also provided with or superposed upon an annular plate 18 directly beneath which, and above V the bottom 14, is arranged an'agitator 19, comprisinga plurality of curved'bladesiixed to an upright shaft 20 journaled yin a"bearing 21 fixed to the bottom 14, said vided with a pulley 22 whereby' it may be operated. The agitator 19 operates in an agitation chamber between'the grating 17 and base 14, and said agitatoris s o formed in the proportioning of its plates, as to draw the water downward through the grating 17 from the interior of the tank. l y

At each of its four sides, each tank is provided with a ixedor detachable diffusion element y23', which said element consists of an upright plate 24 ranging downwardly Y within the tank slightly divergently from the respective side thereof, from a point just beneath the plane 'of the overflow header 8 tothe plane of the corner partitions' 16.` Each of these plates 24 is provided with side members 25 which closely engage with the respective sides of the tank, and each of said plates is preferably e detachably connected with the respective side of the tank, at its upper portion, by means of a screw or bolt 26.

Ashaft projecting beneath the bottom 14 and being pro- Each 0f the plates 24 is provided with two or more transverse seri'es of elongated openings 27, the openings of eachseries-being preferably arranged ina slight curvature, and above each series of openings is arranged a transverse baffle 28 extending between the side members 25. The baiie's 28, when the diffusionelements- 23 are in place, extend obliquely downwardly towards the sides of 'the tanks, and theopenings 27 are formed with substantially the samel oblique downward range.

4The operation, `method of use and advantages lof the improved washing machine embodying the invention will be readily understood from the foregoing description taken in connection lwith the accompanying drawj ing and the following statement.

When steam and water are simultaneously admittedto the headers 3, and from these headers the steam and water iiows into the tanks, and behind two of the diffu- L ings and downwardly onto the dishes.

- agitation is instituted within the tank, when the ow of material sticking thereto; The overflow pipe 9 and disthe water within the tanks. It will be understood that sion elements 23'in the tank or tanks 1,whence the hea-ted water is directed by the bafHes'ZS and through the openings 27 downwardly upon theI dishes which are placed upon the grating 17. At the same time, if the shaft 20 vis operated by the pulley 22, the agitator 19- draws the water downwardly through the several openings 27 'from the spaces behind the several diffusion elements 23, the water passing inwardly through said op eni The water is also forced into the pockets in the corners of the tanks whence it issues through the spaces between the partitions and joins in the general condition of agitation of the operation in each of the washing tanks employed is the same. -lt results from the peculiar arrangement of the diffusion elements 23, the inlet of the first water into the tank behind one of the diffusion elements 2 3, and the combination of such diffusion elements with the agitator 19 and the partitions 16 in part or in whole from suoli arrangement and combination, that a condition of water and agitation of the same is set uup, which is accomplished by an ebullition of the waterwithn the tank in a general downward and upward as well as crisscross or to and iro movement. The downward movement of the wgater keeps the dishes firmly lseated upon the grating 17, and the to and fro or crisscrossmovement of the water effectually dislodges from the dishes any charge pipe 11, through the headers Sand discharge pipes l2, permitof effectually draining the tanks and preventing overflow of the same.

The entire apparatus is very positive and eflicient in operation and comparatively simple and inexpensive in construction, in View ofits eiiiciency; and its particular point of advantage consists of the highly efficient results in operation obtained from the peculiar'arrangement and combination of parts and members causing the downward and upward and crisscros's circulation of the cleansing currents'. n Y

I do not desire to be understood'as limiting myself to the particular construction of parts and members as de- A scribed and illustrated, butjreserve the right to vary the same, in adopting' the improvements to condielements and an agitator located in the bottom of the cusing independent of the diffusion elements.
