Application December 18, 1946, 'Serial No."716,-9197 1 Claim. 1
Specifically, this invention has to .do with a .deviceforuse in washing-dishesand thelike and contemplates an apparatus by means of which -.a modicum of soap or other detergent and/or water-softening agent is continuously added to .a stream of hot water-the treated water being continuously .fed to a brush-or like elementfrom which it flows onto the dish or other article being washed. But in a largersense the invention envisages apparatus whereby soluble material .of vany kind can be intimatelymixed with a stream of liquid solvent solthat the stream of solution discharged from the apparatus contains a substantially constant percentage of solute.
As applied to apparatus for washing dishes and the like, my invention contemplates not only means for continuously treating a stream of hot water with soap or other detergent or with -a water-softening agent, but also embraces, vas-an additionalieature, an arrangement whereby the stream of hot water can instantly be diverted, at the will of the operatonso that it is-discharged onto thedish or other articlebeingwashed without having first passed through that part of the apparatus where the soapor other material normally is added. Thus, the user can apply soaped or otherwise treated water toradirty dish through the medium of a brush or othersoruhbingelement and can immediately thereafter flush or rinse thecleaned dishso as .to remove the residue of soap or other detergent.
One of the objects of my invention is to proyidean apparatus'by means of which dishes and other articles can quickly be washed and rinsed and made ready for drying.
A further object is to provide an apparatus which will emciently add soap or other detergent and/or water-softening agent to a stream of hot water and which will produce agitation such as to thoroughly mix the introduced vmaterial with the water.
Another object is toprovide animproved apparatus by means of which a stream of solvent liquid can .continuously be treated with a solid soluble material and wherein mechanical agitation of the solid soluble material takesplaoe continuously only so longas the liquid is flowingthus ensuring against the occurrence oftoo great a degree of saturation duringperiods when the flow is cut off, but providing for an adequate degree ofsaturation at-allother times.
Other objects andadvantages of my "invention will become apparent as the ensuing detailed .description progresses.

The dish washing apparatus of Figsgl ands-,6, inclusive, comprises 'a casting 10 -ofany suitable material such as aluminum, .magnesiumypllastic or even glass. Said casting l 0 z-includesfa portion l-l 'havinga cylindrical chamber l2 into one end of which is threaded-a removable plug [3 having an external diametrical rib 13a which serves as a finger grip. An annular gasket I 4 serves to keep chamber l2 water tight atthe plugged end.
A-cylindrical rotor I5 is disposed within chamber l2 andhas trunnions I6 and ii! at its-respective ends which function as pivotal supports. Casting ID has an internalispider portion l8 having openings [9 and acentral bore 20 in which trunnion 16 is journaled. i'IYr-unnion I1 is journaled in acentralbore in plug 13. Aspoutportion :2l constituting an-integral part of casting l0 projects forwardly from spider l8 and is adapted to receive adetachable tube 22, shown in Fig. 1, which latter is connected to a rubber brush '23 (see Fig. .1)'-the latter being suitably perforated to discharge a number of line streams of soapy water which is delivered to the brush through tube '22.
and constituting an integral part of-casting 10 v has a conduit 30 extending into the interior of :the valve housing and -is adapted 'to receive a hose :3! by means of which the apparatus is detachably connectable to a1faucet -,32 which :supplies hot water to the apparatus.
A two-way tapered valve plug .33 islseatedsin a tapered bore in housing 26 and has a T-shaped passageway 43 by means of which conduit 30 can be connected with conduit 28 and, alternately, with the bore of tube 24. When valve plu 33 is in the posture depicted in Figs. 3 and 5, a stream of hot water will flow from tube 3| through conduit30 into conduit 28 and thence into chamber l2. when, on the other hand, valve plug 33 is rotated 90 degrees in a clockwise direction, as viewed in Fig. 3, hot water will flow through the valve into tube 24 and will be discharged out of the forward end thereof. The stream of water thus discharged from tube 24 is used for rinsing dishes, and tube 24 may be bent as shown or formed in any other way to suit the convenience of the user. Or it may, if desired, be extendedrod can befinger-actuated against the pressure of a coil spring 38. I The end 'of rod 35 remote from pushbutto'n' 3'! is turned upwardly, as viewed in Fig. 3, and is pivotally connected to a 'valve operatin'g' arm 39 which, in turn, is connected to valve plug 33. Normally, spring 38 holds rod 36 in the position in which it is shown in Fig. 3, wherein the valve is set to pass hot water into chamber 12, and said spring will restore the valve to that position whenever pushbutton 31 is released.
Rotor I 5 comprises a foraminous sheet metal cylindrical shell 39 which is'supported at its respective ends by cylindrical headers or end walls 40 and 41' to which are attached, respectively,.the trunnions lfi'and ll. Header 431s fixedly attached to shell 39, but header 4! is so fitted therein as'to be withdrawable; and formed on the periphery of the latter, in line with the discharge end of conduit 28, is an annular series of tooth-like vanes 42 which completely circumscribes the axis of rotation of the rotor and constitutes a Pelton wheel through the 4 33 to its alternate posture, the treated water ceases to flow from the brush and, instead, a stream of clear water is ejected from the discharge end of tube 24.
In the embodiment of Figs. 2 and 7-9, the casting 53 comprises a cylindrical chamber in which is mounted the. rotor 52. This rotor is identical in construction with the previously described rotor l5 and is pivotally supported at its forward end on a spider 49 which is centered in the bore of chamber 5!. The other end of rotor 52 is journaled in plug 53 which is identical with a plug I3.
agency of which 'the incoming stream of hot water causes rotor IE to rotate on its axis.
Rotor l5 is :filled' orp'artially filled with soap, soap chips or-flake's' or otherdetergent and/or a suitable water-softening agentQand, for the purpose of refilling, it can be withdrawn from chamber 12 upon removal of plug |3whereupon header 4! can be detached from'shell 39 to afiord access to the interior thereof.
The hot water flowing into chamber 12 keeps rotor 15 in motion and some of it filters through the openings in foraminous shell 39, thus coming into contact with the soap or other material inside the rotor. The water entering the rotor is saturated with the detergent or water-softener,
or both, as the case may be, and is discharged through the small apertures'40a in header 40 whereupon it rejoins and mixes with the stream of hot water which is "continuously moving lengthwise of chamber #2 in the spac surrounding the rotor. The treated water passes out through openings [3 and thencethrough the bore zlaof'spoutzl.
In operation, a continuous stream of soaped or'otherwise'treated hot water is fed to brush 23 so long as valve plug 33 is positioned as shown in Fig. 3; but whenever the operator'depresses pushbutton 3'1 and thereby rotates valve plug Casting 50 includes a valve housing 54 having a bore in which is seated a rotary valve plug 55, and the latter is provided with an external manually operable handle 55 by means of which the valve plug can be turned. An upwardly projecting extension 51 connects with valv'e housing 54 and is provided with acup-like enlargement 51a in which is seated a soft rubber liner 58 the bore of which is of suitable diameter to fit snugly over the spout of a kitchenfaucet 59.
A conduit 60 conducts hot water from faucet 59 to the interior of the valve housing where it enters a passageway 6| through valve plug 55 and is thereby directed eitherto 'a' conduit 32, as shown in Fig. '7, or tea conduit 63- -the latter connection being effected by turning valve plug 55 counterclockwise degrees, as viewed in Fig.7.
The water dischargedlfrom conduit 62 strikes the Pelton wheel 64 tangentially, as will be apparent from Fig. 8, and causes rotor 52 to rotate in the counterclockwise direction as viewed in thatfigure. w f
When the valve is turned to the position shown, soapy water is discharged through bore 65 of spout 66 and is thus transmitted through a flexible hose 6'! to the brush 68, which latter may be identical with previously described brush 23. When the valve isturned to its alternate posture, clear hot waterfis transmitted through conduit 63 .intobore 650i spo t 5.6 and thence through flexible hose 61 to brush 68.
While I have shown and'de'scribed only two of the preferred embodiments of my invention, it will be apparent that there are many possible modifications within the scope and purview thereof, and, accordingly, Ifido not wishto be limited except. as indicatedby'the terms of the appendedclaim. a
What I claim as new andwish to secure. by Letters Patent is:
A device of the class, described, comprising a structure shaped to define;a cylindrical chamber with one end'thereoi open, having a substantially tangential inlet port for liquid, leading into thechamber ata point a small distance inwards of theopen one end and also having, an
outlet port leading from the other end ofthe chamber, a spider fixed within, and. extending transversely across, said other .end of the chamber and provided with a central bearing, a solid plug fitting removably within,,and serving as a closure for, said one open endpf the chamber and provided with a central bearing in alignment with the bearingv in the-spider, and a cylindrical rotor disposed in, and extending lengthwise of, the chamber, adapted toret'ain adetergent, and consisting of a continuous ioraminous side wall, a foraminous end wall fixed to the end of the side wall that is adjacent said etherend of the chamber and having a trunnion jourhalledtemovably in the bearing in'the spider, and an imperforate comparatively thick end wall extending across, and removably secured to, the other end of the rotor side wall, having a trunnion journalled removably in the bearing in the plug, and provided with an annular series of integral outwardly extending teeth-like vanes disposed adjacent the inlet port and adapted to be so acted upon by liquid entering the chamber via the inlet port as to cause the rotor to rotate, said rotor being adapted to be withdrawn axially from the chamber upon removal of the plug, and being adapted to be charged with the detergent upon removal of the imperforate end wall from the foraminous side wall.
