My invention relates to dish-washing machines and it has for a purpose the provision of a machine by which dishes of various sizes as well as table silver, may be washed andv rinsed thoroughly, rapidly, and economically and in a manner to permit the continuous feeding of soiled dishes to the machine with a constant delivery of the washed and rinsed dishes therefrom. I

My invention is characterized by employing bodies of washing and rinsing waters instead of Water sprays and the attendant waste of water, through which the dishes are con tinuously and successively. moved in such l5! manner that Washing and then .rinsing of the dishes is effected.

I Will describel only one form of dishwashing machine embodying my invention.

' In the accompanying drawings:

Fig. 1 is a view showing in top plan a dish-washing machine embodying my '-inven'v tion; e l.

. Fig. 2 is a vertical sectional view taken -on the'line 2-'-2 of Fig. 1;

Fig. 3 is a view showing the machine in end elevation;` l.

' Fig. 4 is a central vertical longitudinal sectional -view of the machine shown in the preceding views;

Fig. 5 is an enlarged fragmentary sectional view taken on the line 5-5 of Fig. 4; Fig. 6 is an enlarged'fragl'nentary sectional vview illustratingv the manner in which a dish paeses beneath one of the confining rollers; an A Fig. 7 isa fra entary plan view of one of the conveyor elts illustrating the man-v ner in which a dish is Washed with the slots of the belt to hold the dish in yfixed position thereon.

Referring specifically to the drawings, my invention in its present embodiment comprises a tank including side walls 15, a front endfwall 16, a` rear end wall 17 and a bot-v tom 18. rlfhe tank` is divided transversely into compartments 19 and `20by means of avertically and centrally positioned parti tion 21.which, as shown in Fig. 4, terminates short ofthe top of the tank. An undulated 50 platform 22 is secured within the tank soas conveyor is supported for movement over the the upper edge of the partition 21. The roller V4. The lower stretch of the conveyor, indito extend over the' upper edge of the partition 21, and this plat orm is perforated, as indicated at 23, andslotted longitudinally along the inclined portions as indicated at 24. This platform is designed to support the upper stretch 25 of an endless conveyor belt, and to cause such tretch to define a tortuous path correspon ing tothe contour of the platform. Theu per stretch ofthe platform by means of rollers 26 and 27 are: ranged at opposite ends of the tank, and an intermediate roller 28 rotatably mounted in a pocket. 2 9 formed in the vplatform 22 at 26 constitutes a driving roller and'on the shaft 30, to which tle roller is secured, is a pulley 3 1 about whichis trained an endless `belt 32.for operatively connecting the pulley to the shaft of a motor 33. By this connec 7o tion the motor operates-to drive the roller 26 and thereby impart movement to theendless conveyor for moving the upper ,stretch 25 from right to left as when viewed in Fig.

l'I5 cated at 34, is trained beneath rollers and is extended-through a slot 36 of the partition 21.4 Thesefrollers 35 can be made adjustable to tighten the conveyor and thereby insure 'its proper feeding movement when the roller `26 is rotated.

The endless conveyor is made up of a pluf rality of separate and independent belts, inl dicate'd at B, all of which, however, are trainedabout the rollers 26, 27, etc., so as to bedriven in the same direction by the roller 26. There .is one belt for each of a plurality -of channels formed by the provision of a plurality of flan es or artitionsy F 'se-i cured to,and rising om t e platform 22 and coextensive in length with the platform. .Asshown in Fig. 4, the flanges F correspond in contour to that ofthe platform, while,

as'shown in Fig. 1, the anges 4are s aced apart in su manner thatthe channe sare 95 graduated Width for the purpose of ac 'Y commodating dishes of different sizes.

Eachibelt B isconstructe'd of any suitable-T flexible material and is rovided at intervalsv with transversely exten ng -slots 37 designed for `the purpose of receiving the edges of dishes in a manner to hold the dishes in fixed spaced relation to each other on the belts to prevent piling of one upon another andto storing of the dishes,

thus insure thorough washing of the dishes as they travel through the machine. The manner in which a dish is washed with the belt and slots is clear-l illustrated in Figs. 6 and 7.

At the delivery end of the machine an inclined and stationary platform 38 is provided for conducting the washed and rinseddishes downwardly into a receptacle 39. In this receptacle the dishes are deposited and from which they may be removed for wiping. The fianges F may be continued downwardly of the platform 38, and the receptacle 39 divided into -compartments corresponding to and registering with the channels formed by the flanges in order that the'dishes as collected in the receptacle will remain segre ated as to size, thereby facilitating the su sequent as will be understood.

In practice, the compartment 19 is filled with soapy water, preferably to the dot and dash line shown in Fig. 4. Water is supplied to the compartment 19 from a faucet 40 arranged thereabove, and with this water soap may be mixed in the required proportions to produce a water which is suiiiciently soapy to thoroughly reove grease and other fore1 gn matter adhering to the surface of the es. `-The compartment 20 may he lled with water from a faucet 41. This water is not made soapy as it is designed for rinsing of the dishes previously washed by the water contained in the compartment 19. From time to time it is of course necessary to renew the water in the

com artments

19 and 20 and the old water may e discharged therefrom through outlets 42, normally closed by plugs 43, in the form of rods, movable vertically in brackets 44 and provided at their upper ends with handles 45 disposed above the tank and within convenient reach of the operator.

It will berunderstood that by elevating the plugs the outlets could be opened to permit thedischargeof water from'the tank, the

stretch of the water bein delivered to outlet pipes 46.

The mac 'ne also includes a plurality of rollers 47 as illustrated in serve to maintain the belts in contiguous relation tothe undulated platform which, as a consequence, causes the dishes to describe the undulated ath'of movement of the upper elts. Transverse rods 48 are extended between and` secured to the flanges v against spreading. co

F at the points shown to reinforce the flanges These rods are spaced suiciently from the belts to permit the dishes to pass therebeneath. a

' In the operation of the machine, dishes are introduced into the channels defined by the flanges F and fromthe righthand end when viewed in Fig. 4;.

l chanels of different widths for dishes are now submerged in the clear water contained in 'the compartment 20 durin ventional sizes,

Fig. 4. The rollers.

Y particular channel is determined by the widt of the channel. I consider this an important feature lof my invention as by providing different-sized dishes, the dishes remain segregated as to size during travel through themachine, thus facilitating the wiping and subsequent storing of the dishes.

The dishes delivered to any particular channel `are carried downwardly into the soapy 4water contained in the compartment 19 by the downward movement of the upper stretch of the respective belt. In passing through the soapy `water, .the v'dishes are washed and, undercontinued movement of the belt, arecarried upwardly and free of the soapy water. Under further movement, the

surface of the dishes so that when they are finally carried upwardly and delivered to the ma v ordxer to receive relatively deep dishes such as bowls, the remainder of the channels being constructed to accommodate dishes of conas used in restaurants.

Although I have herein shown-and described only. one Yform of dish-washing machine embodying my invention, it is to be understood that various changes and modilications may be made herein with'out departing from the spirit of the invention and the spiriti and scope of the appended claims.
