This invention relates to dish washingmachines and the prime feature of the invention is the arrangement of the dish holding basket in such manner that when water is injected into the basket for washing the dishes, the basket .will be caused to rotate from the force of the streams of water.

A further feature of the invention is in so arranging the streams ofwater that they will thoroughly wash and rinse all the dishes within the basket;

A further feature of the invention is the provision of means for draining off the water from the dishes, the dishes will dry without showing streaks or tear paths, after thewashing operation has been completed. 4

A further feature of the invention is in so constructing the various parts of the machine that the several parts may be readily assembled together and form a rigid-nonvibrating unit.

A further feature of the invention is the provision of a bearing for the dish receiving asket whereby the friction set up will be reduced to a minimum.

A further feature of the invention is the provision of means for ventilating the interior of the machine during and after the" washing loperation, whereby. the machine will be maintained in a more sanitary condition. Other objects and inafter more fully set forth and pointed out in the accompanying specificatio'n. In the accompanying drawings which are made of a part of thisapplication, Figure 1 is a to plan view of the machine; Fig. 2 is a simi ar view with the top covering broken awa Fig. 3 is asectional view thru the mac ine, substantially along the line 3-3, Fig. 2; and Fig. 4 is a similar view substantially along the line 4.-4, Fig. 2. Referring to the drawings, in' which similar reference numerals designate corresponding parts thruout the several views, 1 indicates the body .of the machine, which is preferably constructed of any suitable sheet metal and 2-indicates the supporting legs.

there or.

Positioned within the body portion 1 is a tank 3, also preferably constructed of suit: ablefsheet metal and supported in any suitable manner, as by means of a cross truss 4,

the ends of which in such manner that advantages will be herewhereby the dishes transparent material may the walls of the are attached to the'walls of the body 1, and a central post 5, the lower end of whlch engages a cross truss 6, the-v - trusses 4 and 6 preventing lateral vibration of-the post. In orderto easily and properly assemble-the post with the two trusses, it is preferablyv made in two sections and secured together by means of a coupling.'(, and said post is preferably hollow, as shown.

The upper end-of the post 5 projects a distance into the tank 3 and receives a hollow sleeve 8, to which is attached a basket 9, the walls of which are preferably constructed of mesh wire 10, so that water may be readily entered thru the wall and onto the dishes 11 stacked therein. The basket 9 is firmly secured to the sleeve 8 bymea'ns of collars 12, while the two sections of the post 5 meattached-to their. respective =trusses'by means 1 of collars 13 and 14. Threaded or otherwise secured in the upper end" of the post 5 is a cone bearing head 15, channel 16 therein to serve as a lubricant retainer and also'to reduce friction. Fitting overthe bearing head 15 is a bearing socket the bearing face'of which has a 17, which is fixed to the sleeve 8, said socket having a nut 18-formed thereon so that the socket may be readily attached to or released from the sleeve, and the bearing head 15 likewise hasa nut 19 formed on its under surface so that a wrench or tool maybe readlly applied for attaching or releasing the headfrom the post 5'. i

The body portion 1 has a covering 20 therefor, which is preferably hinged 'at one edge so that it may beswung to open posltion to give ready access to the basket 9, may be readily introduced into or removed from the basket, and if preferred, a section of glass 21 orother be provided at a suitable point in the covering, thus giving a vision of the interior of the basket and tank, during the washing. operation.

In order to ventilate the lnterior. of the body 1 during and after the washing operation, a series of openings 22 are formed thru ody 1, adjacent its upper edge, said openings being so positioned that the water. employed f .1 Washing the dishes will not cornein contact therewith.

of the waterthru the pipes. The pipes 23 The water for washing and rinsing the for controlling the passage Y and 24 are preferably arranged vertically and on diametrically opposite sides of the basket so that the stream or jets of water from nozzle openings 27 and 28 will strike thebasket 9 at a tan ent, also the dishes therein, the force of t e water serving to rotate thebasket 9, thus brin 'ng the waterinto contact with all the disfi es Within the basket, and by properly arranging the dishes edgewisewithin the basket, substantially all the water will drain therefrom by gravity.

It willlikewise be seen that a certain amount of the water will strike against the walls of the tank 3, and then re ound against the basket 9, the force of which will aid inrotating the basket, as well as aiding in the washmg operation. As best shown in Fig.2 of the drawing, the tank 3 has panels A, which are at an angle to the main walls of the tank, giving'a polygonal outline to the tank, so that the water will more readily re bound when thrown against the walls thereof. The streams of water may have various paths of travel depending somewhat uponother, thus insuringghat all the dishes with in the basket will subjected to the force of the water discharged into the basket from the difi'erent nozzle openin By arrangin' the nozzle openings 27 an 28 in staggere relation, rotation ofthe basket 9, will be assume a more or less spiral or whirlin path and will morethoroughly interming e and give a more perfect washing operation and will materially aid in imparting rotating movement to the basket.

The water when leaving the basket 9, de:

l scends into the tank 3 and is drained therefrom thru adrain 29, which has a valve, 30 foropening or closing the drain. The drain ,29 discharges the water into the body portion 1, from whence it passes into a sewer l v ume of water within the basket wi assume substantially the position thru the regulation drainage 31. y 7. Due to the whirling action of the basket 9, and thru centrifu' al force set u the volnormally shownby dotted line D, 'as shown in Fig. 3 of the drawing, thus providing a wall of water, against which the streams of'water from ;the nozzles strike. 4

In 0 ration, the dishes are first stacked in the asket '9, when the valve 26 is opened and 'jets of water discharged against and the streams of water due to the caused to.

' trates in a thru the basket, the force of the water striking said basket, causin it to rotate, whereby the dishes within said asket will be successively broug'ht into the path of the streams of water, and thus thoroughly cleansed of all adhering particles. After a prescribed length of time, the valve 26 is closed and the valve 30 opened to drain the water into,

the body 1, after which the valve 30 is closed and the valve 26 again opened, thus discharging jets of clean water over and between the dishes as thoroughly rinsing them. A certain amount of water remains on the floor of the tank 3, and also on the floor of the body portion 1, consequently a suflicient amount of moisture is retained around the dishes in the basket'to'prevent' tear paths or streaks forming on the dishes,

traveling whirl pools as indicated by E in 2; and the crest of the water line D is largely composed of such whirl pools.

This com- Referring to Fig.'2,.the letter F denotes a glancin stream of water suchas is caused by one o the spray streams strlkin a dish .11, shown in Fig. 3. Said stream bein thus directed against the walls of the tan]? 3 and glancing therefrom in the form of stream C which sometimes again strikes one of the panels A and thence against the main walls of said tank, etc.

g It will be obvious from the foregoin that the invention sets up a combination of friction, centrifugal force and spray actions which coo erate to give a variety of movements against and between the dishes, thus washed.

While the description and drawing illu'stalities whi may be employed in carrying gieneral way, certain instrumenc the invention into effect, it is evident that many modifications may .be made in the various details, without departing from the scope of the a pended claims, it being understood that t e invention is not restricted to the particular forms, herein described.
