The selector has an inclined flange M on each armat opposite sides of the selector tocooperate with abutments 15 one of which is mounted on each bracket 4, so as to oscillate the selector.- 7 As the carriage Smovesin one direction to the end of the-screwrod 3, one inclined .flange it will engage one abutment 5 to swing the selector Hi from one position to the other,
The selector has a guide tube It to cooperate with each outlet I2 of the nozzle 'sothat. when said guide tube is disposed in aline'mentwith or directlyvbeneath the corresponding outlet,'the fluid jet from the outlet will 'be' directed upon the impeller l so as to actuatethe same, ,As'the selector. is oscillated to bring one guide tube It into alinement with one outlet !2, the other outlet is closed by a valve lip II. on the selector. Gravitational action on the selector tends to hold it in one or the other of its two positions, andQwith the force of the fluid'stream against the walls of the guide tubes it, will hold theselector in one position until it is, moved into another position by engagement of the inclined "Where the unit is used for washing dishes,
it is desirable to place it in a cabinet or casing A at the top thereof so that the dishes may be arranged in a suitable rack B at the bottom of the cabinet and water issuing from the outlets 52 will be distributed over the dishes as the carriage and nozzle moves back and forth along the guide rods 2 and 3 by the impeller 1. In such case, it is desirable that water be supplied to the nozzle [I through a'pipe i8 which extends longitudinally of the cabinet and may be connected to a faucet or other water supply by a hose I9. Intermediate the ends the pipe I8 has connected thereto a T-fitting 23 to which is connected a branch nipple 25 to which in turn 'is' connected one end of a flexible hose 2i which is connected to the nozzle II. The T-fitting 23 has. secured thereto a cap 24 for a soap receptacle 22 which is separably connected to" the cap 24 by screw threads. The cap 24 preferably has .two openings 26 and 21 communicating with the T fitting one opening being larger than the other. In operation, soap or soap powder is placed in the soap container 22 which is connected to the cap'z l, and upon flow of water through the supply pipe E8, the water passes through the openings 25 and 21 into the soap container, causes a turbulent agitation of the soap so as to mix the water and soap thoroughly,
and then passes outwardly through the openings to the nozzle H. Agitation of the water and soap in the container is caused by the openings of diiierent sizes, the inlet being larger than the outlet so that a slight difference in pressure of the water at the two openings is created. As shown, these openin s 25 and 2! are arranged in a common plane parallel with the direction of flow of the water through the nipple 25 into the T-fitting with the outlet nearer the nipple 25. Obviously, if desired, an amount of soap just suificient towash the dishes may be placed in the soap container so that after the'soap has been exhausted a continuation of the flow of water will result in clean rinsing water being sprayed over the dishes, or, if substantial soap is placed in the container, the rinsing may be done by means of the hose l9.
For the purpose of breaking upthe water jets into a spray and more widely distributing the supply over the dishes, the ends of the blades of the water wheel or impeller may have transverse annular flanges 28 upon impact with which the water will be diffused, and which due to the rotation of the blades will widely throw the spray laterally from the impeller.
Preferably the screw rod 3 is in the form of a round metal rod having a coarse screw-thread or helical groove and the sleeve 6 has a smooth interior and two pairs. of diametrically opposite openings 29 in which are arranged balls 30 to ride in the grooves of the thread and cause coaction of the sleeve with the thread to produce longitudinal movement of "the sleeve upon rotation thereof. The balls 3% are held in the openaiddsia ings29 by collars 3| which may be screw-"threaded on the sleeve. This construction ensures"a smooth and easy rotation andj noiseless longi being that in'theunit shown in Figures. lZto l4 the'outlets 12%) of the nozzle 5 l0 are arranged so e as to direct the jets offfluid therefrom outside or clear of the impeller, and the selector I00 has the guide tubes I69 arranged so that in onejpo- 'sition each guide tube registers with one of the outlets {20 to directwater onthe impeller; and in the other position the guide tube is 'outof ali'nement with thefoutlet. The selector is oscillated to move the tubes from one position to theiother by the flanges I4 and abutments as hereinbefore described, and in operation of the unit, while the fluid is turned on,jets issue from both of the outlets 126, but the jet from one out let is directed by the corresponding, guide tube 160' so as to impinge upon the impeller, while If desired, deflectors i2! may be mountedon the carriage B beneath the outlets I so as to break up thestreams or jets of water from the outlets into drops or a spray and scatter the water over the articles being washed.
Figures '7 to 11 inclusive show the form of the fluid spraying and distributing unit described and claimed in my above-mentioned copending' application. .In this form of the invention, the fluid spraying and distributing unit includes the iwhich is. a stationary screw rod or shaft. A
two parallel guide. rods 2 and 3 the latter of traveling sleeve or nut Ea is mounted on and has a screw-threaded, connection with said screw rod 3 to coact therewith so that upon rotation of the sleeve nut it will travel longitudinally of the rod.
A fluid actuated impeller or water wheel 1a oriphery of said impeller consisting of a ring of close-mesh fabric, such as wire gauze, which is transversely corrugated to have a wave-like its arms, thesleeve nut Ba andwater wheel 'ia,
so thatupon movement of said nut and impeller longitudinally of the'screw rod, the carriage is moved by and with the nut.
'The impeller and nut are rotated by fluid streams or jets from the two outlets 2 9 of a nozzle Ila which is oscillatably mounted intermediate its ends on a nipple lib projecting up- ..wardly from the base portionof the carriage 8a..
The nozzle Ho is hollow and the nipple ilb has diametrically opposite openings Ho communicating with the nozzle. The nipple has connected thereto an elbow 2B which isin turn connected .to a flexible hose 2! which can be connected to a fluid supply, for example, a faucet a, of a dwelling house water supply system.
in one direction. nozzle are thereby moved longitudinally of the the free end of the lever lflb'whereupon the The nozzle is'arranged and oscillated on the carriage so that the outlets I21) may alternately direct fluid streams or jets on opposite sides of the periphery of the impeller to cause the impeller to rotate alternately in opposite directions and "5 thereby produce movementof the impeller and carriage longitudinally of the screw rod alternately in opposite directions. As shown, the nozzle is oscillatory in a plane transverse of the plane of rotation of the impeller, and is arranged with one outlet at each side of the impeller :so that one or the other outlet I211 is locatedabove and in line with. the impellerto directa fluid stream thereon,while the other outlet is located beyond one end of the impeller so that the fluid stream will flow clear of and will not impinge upon the impeller, and upon oscillation of the nozzle alternately in opposite directions, first one and then the other outlet i227 is brought into," position to discharge fluid upon the impeller.
For oscillating the nozzle, I have shown a system of levers and aspiring which are actuated as the carriage Sa approaches the ends of the screw rod so as to swing the nozzle with a snap action from one position to the other. One lever lilo; is pivotally mounted at lllb intermediate its ends on the base portion of the carriage and has at one end a pair of divergent arms 9 to engage the respective supports or insidewalls of a cabinet v3 at the ends of the guide rods 2 and 3. Another lever !8b is pivotally connected at one end 180 to the carriage and is connected adjacent its other end by a yoke 18a. to one end of the nozzle. A compression spring 16a is interposed between the-last-mentionedend of the lever l8q and the end of the lever Hlgz opposite the arms S and for holding said spring against displacement I have shown a pin ifib'slidably mounted at one end in a block I60 which is pivotally connected at lEcZ [to the lever la, and with its other" end 40 in abutting relation to the free end of the lever I812. With this construction, the levers Illa, [3b and spring 56a normally hold the nozzle Ila in oblique relation to the carriage in the position described and against one or the other of two stops 81) on the carriage, and with one arm 9 abutting the adjacent arm of thecarriage.
In operation, when water is supplied to the nozzle, as by opening the faucet 25a. a stream or of jet of water is directed frornpne'outlet I223 upon the impeller 7a so thatthe force of the stream and. the weight of the water accumulated in the openings ofthe wiregauzero'tates the impeller The impeller, carriage andaig guide rods until onearm 9 strikes the support or side of the cabinet. Thereupon, the lever [Ga is swung until a dead center relation is reached between the end of the lever, the pivot "Illb and spring with a snap action or jerk completes the swinging of the levers and moves the nozzle so as to bring the other outlet |2b into position to discharge a stream of water on the impeller, m.'ove-" ment of the nozzle and levers being limited by the stops 8b and engagement of the arm 9 with the carriage, and the spring and leverspositively holding the nozzle in the proper position. The impeller is then rotated in he opposite directionjm and the carriage moves toward the other end of the guide rods until the other arm 9 engages the support or cabinet, whereupon the direction of movement of the 'impellernnd carriage is again reversed in the same way. This actioncontinues until the water is shut off at faucet 25a, so that the nozzle is moved back and forth along the guide rods and the water therefrom is sprayed and distributed over the articles, for example, dishes, being washed or sprinkled.
Where the fluid spraying and distributing unit is to be used in a dish washer, it is desirable that the unit be mounted in a casing or cabinet which shall prevent splashing of the water about-the room, and which shall be convenient for the placing and removal of dishes into and from the cabinet. A desirable form of cabinet is shown in Figures 1 and 2 of the drawings, said cabinet including a body portion having a bottom 35, end walls 36, rear walls 3'! and a front wall 38. This front wall is shorter than the rear and end walls, in other words, terminates short of the top edges of said rear and end Walls. At the top of the rear wall 31 is hingedly connected at 39, a cover or top section 40 to the ends of which are connected the brackets 4 of the fluid distributing means so that the unit will move with the cover into an out of the way position as the cabinet is opened to insert or remove dishes. For bridging the gap between the front end 4| of the cover and the front wall 38 I provide an intermediate front wall section 42 which has end wings 43 pivotally mounted intermediate the ends at 44 on the inside of the end walls 35. The free ends of said wings 44 are pivotally connected to a link 45 which is also pivotally connected at 46 to the cover section MB, for example, to the water supply pipe l8, as shown. VVith this construction, as the cover section 4% is raised or opened, the intermediate front Wall section 42 is lowered into the body section to a position behind the front wall 38, while when the cover is closed the front wall section 42 is elevated to close the space between the front wall 38 and the cover. Easy and convenient access to the dish rack B is thus afforded and the dangeriiof dropping the dishes as well as discomfort which would be incident to reaching downwardly into the casing from a position in line with the top edge of the end and rear walls, is eliminated.
Preferably the cabinet is of such size that it can be set into or in convenient relation to a sink, and drain openings 41 are provided in the bottom of the cabinet so that the water can be easily and quickly drained therefrom.
