' r uApp fiation August 11, 1930; manna-474,523 'J cclai sp(o1.'259 95i This invention relates to mixing devices particularly adapted for dishwashing machines, and more particularly to devices of this character peculiarly conceived in a manner to dissolve a cleaning compound 'in'water whereby the same may be admitted as a solution to the machine;

The object, generally stated, is the provision of novel means constituting a jet having improved capabilities affording .a most efficient agitation vof water and an introduced cleaning compound and wherein saidagitation iseffected in a communicating drum separable and auxiliary to the machine, propen A further and more particular objective resides in the adaptation of peculiar connections between said tank and the machine, advantageous in the provision of an indication to an operator of the completion of a mixing cycle,'and tothe end of affording an admission, by the operator, of a desired quantity of the water and the admixed compound to the washing machine.

Further and more particular objects andadvantages, together with the foregoing, will appear throughout the course of the following detailed description, the invention consisting in the novel construction, adaptation, and combination of parts hereinafter described and set forth in the annexed claims.

In the accompanying drawing,- V

Fig. 2 is an enlarged detail side elevation of the nozzle shown in the preceding view.

Fig. 3 is a plan view thereof, with parts in-section; and

Fig. 4 is a diagrammatical view. taken in plan to illustrate peculiar agitation of water.

Before proceeding with a detailed description of the particular embodiment herewith shown, itis to be noted that :While auxiliary feeders have heretofore been used in isolated instances, such have not been generally accepted, due primarily the discharged to the fact that the compound introduced to the water settles out of solution with'a resultant meral 5.representslarectangular tank having suitable inlet 8 for the introduction-of thecompound, and respective outlets 6, 7 disposed in l proximity? ofthe floor and ceiling, 9, 10, respec tively. 'More. particularly, outlet 6 constitutes what will hereinafter be termed the drainage outlet,'7 comprising an overflow having a pipe 11 interconnected through a by-pass 12 to the pipe lead 13 from a cook 14 of the drain 6. The discharge main'l5, common to pipes 11, 13, communicates to the intcrior'of the washing machine 16. Coupled to project within the aforesaid tank 5 to a point relatively adjacent floor 9, I provide a nozzle 20, a suitable valve 21 therefor being adapted to control the discharge of hot water froma pressure supply pipe22. 23 indicates a stufling box; 7

Said nozzle, moreover, is conformed such as to lets 24, 25 converging rearwardly and upwardly present oppositionallydirected constricted cute tojmerge, one with the other, at a point removed, 7 more especially as in conventional Siamese type couplings. l

With particular attention being directed to Fig.4., a discharge of diverging jets, responsive to contactual banking engagement to the oppositional side and end walls, attains a gyratory activity to eifectively stir the constituent parti-. cles of the cleaning compound in attracting the same into a state of solution, or, assuming an admission of the compound in excess of a saturation point, a state of suspension due to the allocation of the nozzle discharge in affording excessive turbulence in proximity of the floor.

As the water level risesresponsive to pressure admission, overflow pipell drains through discharge main 15 to indicate a thorough admixture of the compound and water, a selected amount, such as desired, being subsequently withdrawn'through drain cook 14. a

'I'he'invention is believed clear from the foregoing, and while Ihaveherein illustrated and particularly described a preferredembodiment now best seen to attain novel objectives contemplated, it is not my intentionlto confine myself particularly thereto except as by the scope of the hereto annexed claims.

What I claim is,- l l 1. The combination with the auxiliary mixing tank for a washing machine, said tank being adapted to dissolve a cleaning powder or the like.

in water to form a solution, of means for accelerating said dissolving action, said means comprising a pipe leading from a pressure source of water supply and projecting into the tank at the inner walls of the tank, said goose-neck configuration of the pipe allowing free movement of the swirling eddies of water belowthe same'to prevent settling of the cleaning compound rearwardly of the discharge nozzle.

2; The combination with the auxiliary mixing tank of a washing machine, said tank being adapted to dissolve a cleaning'powder or the like in water to form a solution, of means for accelerating said dissolving action comprising a water pipe from a pressure supply projecting into the tank 'at a point materially elevated above the floor of the tank,- said projecting end of the pipe within the tank being curvedto a relative gooseneck configuration with the terminal end of; the

same located in proximity of the floor of the tank and providing a discharge nozzle, saidgoose-neck configuration'of the pipe allowing unrestricted movement of the water below the same to pre- 7 vent settling of the cleaning compound rearwardly of the discharge nozzle. 1 i

3. In combination with the auxiliary mixing tank of a washing machine, said tank being adapted to dissolve a cleaning powder or the like in water to form a solution, means for accelerating said dissolving action comprising a a water pipe from a pressure supply projecting into the tank at a point materially elevated above the floor of the tank, said projecting end of the pipe within the tank being provided with a discharge nozzle adapted to project a stream of water in a plane approximately parallel with the floor of the tank and saidprojecting end extending inwardly and then downwardly to locate the nozzle in proximity of the tank floor to allow unrestricted circulation of water rearwardly of the nozzle in preventing settling of the cleaning compound behindthe nozzle.
