TABLEWARE WASHER.

Application filed October 13, 1926. Serial No. 141,398.

The invention relates toimprovements in dish or tableware washing apparatus and particularly to a type in which the cleansing is effected by subjecting the ware to a spray of cleansing orrinsing fluid under pressure. An object of the invention is to provide a traveling sprayer conveyed in a cycle about a net form of tray or holder in which the ware is placed or stacked to spray or shower the ware with either a cleansing or rinsing fluid delivered under pressure progressively.-

in downward, upward and lateral varying angular directions to enable all sides or surfaces of the ware to be reached without agili5 tating or moving the ware. v

Another object is to provide a dish or table ware washer as a po rtable cabinet with a washer compartment and a plurality of dif: ferent fluid supply reservoirs beneath the compartment, the compartment and reservoirs being under drainage connection for conveying the fluid back to the reservoirfrom which the supply was taken, and a motor driven pump adapted to be'thrown' in c0nnection with a selected reservoir for delivering the fluid therefrom under pressure to a traveling sprayer in the washer compartment,

the fluid from the reservoirs to the pump and the drainage from the washer to the reservoirs being under a single control for alternately utilizing the fluid from the reservoirs independently. I

Further objects and features of the invention relate to details of construction of the mechanism for simultaneously controlling a fluid supply from several reservoirs to a pump and a drainage connection back to the reser'- .voir adapting the supply to be taken alterna'tely from thereservoirs by the manipulation of a single control lever.

Other adv ntages, features and details of construction 11 the embodiment of the invention selected for illustration will be more fully set forth in the description of the accompany- Figure 5 is a section on l1ne 5+5 Flgure 3.

The apparatus herein disclosed is primanly as a portable dish washer, particularly for domestic service, and therefore, as a unit includes a plurality of liquid holding reservolrs, one for a-washing or detergent fluid, and a secondfor a. rinsing fluid, which traveling sprayer within the washer compartment, and from which it drains back into the reservoir, provision beingmade for alternately controlling the discharge from the reservoirs or drain thereto.

Referringlto the drawings, 1 indicates a portable cabinet preferably constructed of sheet metal and interior-1y subdivided to pro.- vide a washer compartment 2, reservoirs 3, 4',

beneath the washer compartment, and a 5 pump compartment 5. The washer compartment upon its opposite end walls. and toward. the base thereof is provided with ledges 66. of angle iron construction for supporting a moved from the washer compartment through an opening in the front wall of the cabinet which is provided with a door 8 swinging downwardly as illustrated in dot and dash line, Figure 2. The ledges 66 as shown in Figure 4, rearwardly' are spaced from the end walls to provide a passage or clearance for the traveling sprayer pipe 9 conveyed in a rectangular course or path com.-

pletely about the dish-holding tra 7 by an 160.

endless carrier or sprocket chain 10. The sprayer pipe extends horizontally with its sprayer nozzle-.11 at the forward end of the pipe 9 disposed approximately medially of 7 the tray. The dishes and chinaware arestacked and positioned withinthe tray so that their surfaces can be reached from all sides from the sprayer nozzle in its travel about the tray. 1 The dishes thus remain stationary during the-washing operatlon'so that there is no cause for them to become broken glass ware, are placed in an upset position of chipped.

The spraying nozzle is of a form to give a wide spread to the fluid and as it asses about the tray is always directing the uid against thedishes in various lines and angles downwardly and upwardly, so that a complete washing and rinsing is obtained ina considerable less time than would'be possible in moving or agitating the dishes in the fluid. The dishes are preferablystacked or set at an angle whilethe cups, deeper vessels,'or

so that the fluid will be drained therefrom onto the inclined base 12 of the washer com partment. The nozzle travels at an-appropriate rate and'the fluid is projected at a high velocity,- subjecting the ware in the tray to a heavy shower of fluid which completely cleanses the same. The fluid after striking the ware drains therefrom upon the base of the washer compartment and into the proper reservoir 3 or 4. The sprocket'chain or endless carrier 10 is engaged upon the sprocket wheel idlers 13, four in number being provided so that the chain will move in a rectangular path and each sprocket wheel is respectively journalled'upon'a stud 14 fixed to the rear wall of the cabinet or washer compartment. The chain is transmitted by a sprocket wheel 15 connecting with a'sprocket chain '16 leading into the motor compartment and connecting about a sprocket wheel 17 upon the drivin shaft of the pump 19. This pump sha, is driven by a rocket wheel 20 connecting with a chain 21 which in turn shaft 23 of an electric motor 24 on aplatform 25 supported in the motor compartment 5.

The sprayer pipe 9 is suitabl secured to the sprocket chainand connects t rough flexible 'tubing 26 and universal coupling,-

stationary suppl pipe 27 g V The supply pipe 27 extends through the base 12 of the washer compartment into the pump compartment and is rigidly fixed thereto by'the lock washers 2828 disposed at opposite sides of the base. The portion of-the supply pipe within the pump compartment has an L extension 29 connecting with the pump 19 and a drain valve '30 at its lower end. A pair of pivotally connected li'nks 31, 32, are respectively pivotally connected. to the upper end of thesupply pipe 27 and the sprayer pipe 9 and serves to sustain the sprayer pipe in a horizontal plane, the links moving with the sprocket chain about the universal coupling connecting "the tube 26 with the supply pipe 27. The tube 26 and sprocket chain 10 are interposed between the rear' cabinet wall and partition plate 33 in the washer compartment, the partition plate being fixed to the ledges 66.' i

The fluid reservoirs 3, 4, connect with the pump, each through a plural way valve 34 controlled by a hand lever 35. Reservoir 3 connecting with the valve through a pipe flfid after it has been sprayed over the dishes, drains through a spout 39 into either of the reservoirs 3, 4, depending upon its setting, the spout being swivelledupon anipple 40 engaged through and fixed to the base 12. The spout 39 is actuated in conjunction with the valve handle 35 by means of a link 41 connecting the spout with a crank lever 42 swivelled in the bearing 43 of the wall of the reservoir 4, and the crank lever 42has a second arm 42 which connectswith' a link or fork 44 pivoted at 44 to the front wall of the casing. The fork end of the connecting link 44 en gages an eccentric 45 fixed upon the valve stem of the plural way valve 34. Thus, with the shifting of the valve, the-spoutis appropriately swivelled for draining into thetankfrom the washer compartment through the spout. These strainers are arranged to be 95 removable, access to them being had through the opening 48 in the'base 12, the base beingflanged upwardly about the opening for receivmg the cover 49.

In the operation of the washer after the I tray 7 containing the dishes or ware has been placed in the washer compartment 2, the valve handle 35 is thrown in an appropriate direction for conne cting the pump witheither reservoir 3 or 4 which contains the cleansing v fluid. This action simultaneously moves the spout 39 so as to drain the fluid from the washing compartment into the reservoir from which'the fluid is takenby the pump. Upon starting the pump the cleansing fluid from the reservoir 3 is delivered to the sprayer nozzle 11 from which it discharges in a spray upon the dishes. The carrier orsprocket chainlO carrying the nozzle 11, being in transmission connection with the pump, is, thus, thrown into operation simultaneously withthe pump for moving the nozzle at an appropriate rate about the tray or dishes. The sprayer nozzle in traveling about the tray'directs the ray .first'in'one direction, say downwardly om v 've the tray, against the dishes or articles the tray and then follows in an o posite di- 'rection upwardly from beneath t e tray so Y that practically all surfaces of the dishes are reached, it being recognized that the dishes are suitably, stacked in the tray so that aco'nsiderable area oi each dish can be reached by the sprayer. The placing of the dishes, of course, is under the discretion'of the operator so as to produce the most eflicient result for the kind and condition of warewashed, and likewise, the period for which the different sprays are run. After the ware has been subjected for the necessary period to the spray of the cleansing fluid, the handle is thrown to a reverse position which cuts oil the cleansing fluid supply to the pump and puts in the rinsing fluid with the sprayer continuing in its travel. The control of the handle 35 likewise controls the spout 39 so that in shifting from the cleansing fluid supply to the rinsing fluid.

supply the spout is thrownlfrom said reservoir 3 to reservoir 4 so that the rinsing water is recovered or drained back into the reservoir for replenishing the supply to the pump. If necessary, a second cleansing operation and rinsing operation can be had, that is, the change from one fluid to another can be made at any time preferred by the operator.

Having described my invention, I claim: 1. In a dish washing machine, a casing, a dish-holding tray removably supported with- .in said casing, a fluid sprayer traveling in a rectangular path about said dish-holding tray, and an endless carrier within said casing for conveying said sprayer about the tray.
