DISI-IWASHING MACHINE.

Application filed May 21, 1923, Serial No. 640,337. Renewed November 23, 192:7.

In carrying out thisv object 1 provide a plu-y rality oi tanks divided into independent and successive compartments into which dishes may be delivered. The tanks mentioned are designedto receive diil'erent types of dishes and each is equippedwith mechanisms for continuously moving thedishes through the successive compartments and to thoroughly cleanse and vsterilize them during their travel.

One form which theinvention may assume is exempliiied in the following description and illustrated by way of example in the accompanying drawings, in which:

Fig. 1 is a plan view" of a machine embodying thepreiferred form oi: my' invention.

Fig. 2 is a longitudinal section through the same taken on line`2--2 of Fig. 1.

Fig. 3 is a sideelevat-ion of the drive side of the machine.

Referring more particularly to the accompanying drawings, 10 indicates a rectangular housing which longitndmally divided into` a plurality oi independent tanks by partitionwalls 11. These vtanks are" preferably formed of different widths to accommodate various types oidishes, bowls, cups and other likeutensils. The tanks are each divided transversely by partition walls 12 yinto independent and successive compartments as shown in F ig. 1. The tanks `in present instance each comprise an equal ynumber ot' compartments. However, it is understood that any number of tanks and compartments may be employed and also that the machine may be designed to operate on culinary utenf sils other than the articles previously mentioned.

The feed end of the machine is iitted withl aninclined shelf 1.4 to which articles to be washed are delivered. This shellg partitioned by continuations of the longitudinal partition walls of the tanks and is positioned adjacent an entry opening 15 in the end wall 16 of the housing. lhis opening communicates with the first compartmentl'? of each tank. The compartments ot the tanks are tit-ted with inclined false floors 18 which are preferably constructed of `oraminous mateintermediate the lowerr ends of the false floors 18 of the compartments and the upper end of the ialse floors 'of the adjacent cin# i partments. These conveyors are fitted with lugs 21 and are disposed hon an incline `opposite that of -the false doorniembers. The conveyors are designed to .operate to elevate dishes lowered to the bottom ot thecoinpartments and deliver them to the nent compartment. In this manner` dishes fed totlie delivery shelf 14 are `continuously conveyed through the compartments. The dishesare elevated from the last compartmentlby a con veyor'22 and delivered to an inclined drying tray23 located at the discharge end of the machine, i

` The first two compartments oi each tank are tted with upper rotary brushes 2a which are disposed above the talseitioors 18.' lt

intended that'fthe upper and lowerbrushes 19 and 24 cofoperate to wash the surfaces of dishes fed to the machine. 'l l Y Two of the tanks, those indicated at 25 and 26, are of a width to `accommodate bowls, cups and the like and the brushes 24 therein, in the irse compartment, are connected 'with their drive shaft yby a universal joint 25a. lt will be noticed that the transverse shaft which drives the brushes 24 is formed of two parts which project inwardly from opposite. sides of the tank. l@ne of these parts, indicated by the numeral 24a, extends through the outer partition of the compartment-.26 a slight distance and connected to the c orc of the brush by the universal oint 25a. Y This' universal `joint may be of any standard eonstruction, permitting the free end oi the brush to be forced downwardly as will be described.` The connection beiweenthe other brush 24 and the other part of the shaft 24h is exactly the same. This construction permits them to be projected into the interior of a bowl or cup to wash the same. For this purpose the brushes are connected by links to pivoted levers Q8 located at the top of the housing. By referring to Fig. 2 it is obvious that the levers may be manipulated to insert the brushes into cups or bowls disposed there beneath.

rI'he compartments ot the tanks are each tilted with 'a valve controlled inlet pipe 2l() which connects with a suitable source of water supply. rI`he compartments are also fitted with valve controlled drain pipes 3l which connect with a conunon outlet pipe so that the water in the tanks may be changed as desired.

Gas burners are mounted below tanks Vfor the purpose olf maintaining the water therein at a high temperature. A gas burner 33 is also disposed below the drying tray and may be employed to dry thc dishes after they have passed through the tanks. It is understood that other means may be employed to heat the water in the tanks and dry the washed dishes.

For continuously driving the conveyers and the brushes, I provide a drive ,shat't :il fitted with a pulley which may be connected by a belt to a pulley et a driving motor. The drive shaft is also littcd with a pulley 3G connected by a belt to a pulley 37 on a. shaft of convejvers i2() in the lirst compartment., This shaft is connected by sprocket and chain mechanism 39 to the lower shafts 40 of the other conveyors Q0. These shafts are connected by spur gears 4l to the shafts of the rotary brushes l). The upper shafts l2 otl the conveyors in the first two compartments are connected by sprocket and chain mechanisms to the sha1 ts of the rotary brushes 2l. It is obvious that when the drive shaft is driven that the conveyors will operate continuously in the same direction and that the rotary brushes will be revolved.

In operation, tanks are iilled with water from the inlet pipes 30 and the gas burners are started to heat the water to a high temperature. A cleansing solution may be placed in the first two compartments olf the tanks but it is preferred that the last compartment contain clear water.

Dishes or other similar articles to be washed may then be fed to the delivery shelf land will lower by gravity downwardly into the tanks along the false floors 18 and between the brushes 19 and 2l. In the case that cups and bowls are being washed, the levers 28 may be manipulated to project the brushes 2l in the tanks Q5 and 2G into the cups or bowls to wash them.

When the dishes reach the bottom of the first compartments the lugs on the conveyors 20 engage them and elevate them to the the false floors of the succeeding compartments wherein they undergo a second washing.

By the time dishes reach the last; conipartment they are thoroughly washed and the clear .vater in the last compartment arts4 to rinse and sterilize them.

It. is reen that by the provision ot` the separa inlet and drain pipes, the compartments el' the tanks may be cleaned and drained as ol'ten as desired.

lf`rom the foregoing it` is obvious that a very desirable machine has been provided which may be elliciently operated to thoroughly wash and sterilize dishes and like articles.

wWhile l have shown the preferred form of my invention, I wish it understood that various changes in the construction and arrangement ol the various parts of my device may be made without departing from the invention delined in the appended claims.

llaving thus described my invention, what I claim and desire to secure by Letters Patent l. it dish washing machine comprising a housing divided transversely into three independent compartments, separate fluid inlet and discharge connections for each of said comiartments, said housing being formed with an entry opening at one end and an exit opening at the other end, a loraminous inclined lloor member in each compartn'icnt, :Said lloors being disposed in parallelism, and cach having an opening therein adjacent its lower end, transversely disposed lower rotary brushes disposed one beneath the lloor memi ber in each compartment and projecting partly through the opening therein to engage dishes passing over said floor, upper rotary brushes disposed one in each ot the tirst. two comlgmrtments, said brushes being disposed above the lloor members whereby dishes pas-ing over the loor members will pass between the upper and lower brushes and be engaged thereby, an inclined conveyor in each con'ipartnicnt, said conveyor being inclined oppositely to the floor member so as to be disposed between the lower end oll the loor member in the compartment and the upper end ol" the lloor member of the succeeding compartment whereby dishes fed into the lirst, coinpinftment will pass downwardly over the iloor member between the brushesand then be elevated by the conveyor and deposited upon the top olf the lloor menibcr oll the succeeding compartment.
