be also utilized in place of, and as a substitute for, the ordinary sink for houses and apartments.
In my copending application Serial No. 31,971, filed May 21, 1925, for household washing machines, I have described and claimed an improved machine for washing and sterilizing dishes and the like,,'including an improved top spray for such machines. Because of the construction of such improved washing machine, it is impossible to utilize the same'in its resent condition as asubstitute for the or inary kitchen sink, and, further, while the form of top spray therein shown and described is efiicient, it very often happens thatit is desirable to employ a spray that will deliver more water than 18 poss'ble in such a machine. The present invention, chine capable of being used as a substitute for a kitchen sink, performing either of the functions of a' dish washer or a sink, although not both functions simultaneously.
In a dish washing machine of the character disclosed iii the present invention, the water level in the washing tank need not be excessivel high, and, in fact, it is better that the ta be not over one quarter full as it is found that the dishes are more successfully washed, cleansed and sterilized if they are located in what) is really a vapor chamber, the watering fluid seeming to wash more efliciently if the water flows over the dishes rather than to have the dishes set in a lar e volume of water. In a sink, it is often advisable to fill the same entirely full of Water. An object of the present invention is the provision of an improved means for maintaining, at will, different levels of water in a tank that is suitable for'use as In the accompanying drawin s illustrating the preferred embodiment o my invention Fig. 1 is a front elevation, Fig. 2 is a side levation' partly in section;

Fig. 7 is a detail view, partly in section, showin a modification of the upper spray manifo d.
a shallow basin substantially rectan ar in shape and to each corner of which is secured ring 16, the ring 16 forming the upper ed e of the or rim of the basin or tank comprised members 10, 14 and 16. vFormed integral with, and depending downwardly from, the bottom of the basin is a chamber 17, one side of which is rovided with an opening 18 and to this si e of the. chamber 17 and surrounding the opening 18 is a ump chamher or cylinder 19 having rotata 1y mounted therein the impeller 20. Extending outrwardly from the chamberv 19 on the side remote from the chamber 17 is a hollow bearing 21 the outer end of which is threaded and has secured thereon the packing nut" 22. Loosel fitting in the hollow bearing 21 and secure therein by screws 23 is ,a bearing collar 24 of any well known anti-friction metal, and rotatably mounted .in thisbear ing collar 24 is a'shaft 25 formed inte al his with',or secured to, the impeller. 20. shaft 25 is threaded at 26 to receive a packing nut 27 andby means of the bearing collar 24 isvforced into close association with. the outer end of the impeller 20. Surroundin 1 the shaft 25 exterior of the :nut 27 an interior of the packing nut'22 is, the a usual packing material 28. With the construction just described, I obtain a bearing for an impeller 20 that is self-centering anti-friction thatit needs no lubrication, no
ply pipe when the apparatus is to be uti- .lize
Referring to the drawings, 10 desi nat'es 32 of an electric motor or other device 33 which is secured by bolts 34 to bosses or projections 35 formed on the lower or bottom surface of the basin 10.
The chamber 17 connects with the basin 10, and at the upper portion of this chamber 17 is rovided a 'screen or sieve 36 in which collects garbage, grease, etc., that may be washed from the dishes, cutlery, or the like, located in the washing chamber. To the exit end of the pump above described is connected one end of a pipe or conduit 37, the .other end of which is secured in any suitable manner to the bottom of a modified T or elbow 38, and within this modified T or elbow and cooperating with a packing ring'39 therein is a pivotallymounted flap valve 40 which prevents entrance of fluid to the pipe or conduit 37 toward the pump, but does not prevent exit of fluid from such pipe. On the rear of the device the wall of the base 10 is provided with an orifice through which extends the threaded end 41 of the intermediate portion of the modified T or elbow 38, and on this threaded end is screwed a ring 42 .for making a tight joint between the casing 10 and the modified T or elbow 38. ,A passage through the threaded end 41 connects the interior of the modified T or elbow 38, and therefore the pipe or conduit 37, with the interior of thechamber formed by the members-10, 14 and 16. Threaded into an opening into the top of the modified T or elbow 38 is the lower end of a water distribution pipe or conduit 43 which extends upward] to a point adjacent to the member 16 an to the to secured an elbow 44, the other en of this elbow being secured to the member 16 by bolts 45, an orifice being provided in the rear portion or wall of the member or ring 16 communicating with the elbow. Located to the rear of the device and preferably forming part of the drainboard of the combined washing machine and sink is a member 46 to the front edges of which is pivotall mounted by hinges 47 a cover 48 provi ed on its interior surface, with a depending rin 49 of the same shape as the interior of the rin or member 16 and of such size as to fit within said rin or member 16, as clear}; shown in Fig. 2. he rear portion of this epending ring 49 accommodates the orifice 50 that communicates throu h the o ning in the ring or member 16 with the e w 44. Secured to the lower interior edge of the depending ring 49 is a sheet metal member 51 spaced apart from the deend is pending member 49 and'the inner surface of the cover 48 to define thereby a manifold 1 consisting essentially of an encircling chamber 52 and a central chamber 53, the member 51 being provided with a plurality of perforations as 54 through which water or other washing liquid may be forced. It is obvious from the above description that, if water is forced through the pipe or conduit 37 by means of an impeller 20 of the pump, such water or other fluid will be forced through the member 41 into the lower part of the chamber formed by the members 10, 14 and 16 and will also be forced upward through the pipe 43 and elbow 44 into the chamber formed by the cover 48 and inner member 51 and such water or other fluid Wlll be forced downwardly through the erforations 54 in the form of a spray. he hollow threaded member 41 of the modified T or elbow 38 is of such shape as to receive the end of a manifold comprised essentially of a pipe 55 having connected thereto a plurality of laterally extending perforated pipes 56, the perforations in such pipes being on an upper portion thereof so as to direct a spray of water or other washing liquid upwardly in the tank composed of the members 10, 14 and 16. The manifold composed of the pipes 55 and 56 may readily be removed from the hollow portion 41 when it is desired to utilize the apparatus as an ordinary sink, by withdrawing the end of the manifold from the member 41. Secured to the rear portion of the ring 16 is a control switch 57 having a plun er formin part thereof extending througfi the mem r 16 and into the path of movement of a boss 58 formed on the depending ring 49 that is attached to the'cover plate 48. This control switch 57 is connected with any suitable source of power (not shown) and in the usual manner with a motor 33. As the manner in which such connections are made is not important as far as concerns the present invention, they have not been shown and will not be further described.
Screwed into the modified T or elbow 38 intermediate its top and bottom and connecting with the interior thereof is one end of a supply pipe 60, the other end of which is screwed into a T 61 provided with a stop plug 62 and having screwed into the upper portion thereof the lower end of a supply pipe 63, the upper end of this supply plpe being screwed into a T 64. Toy the other end of the T is screwed a pipe 65, the other end of this pipe being screwed into one end of a valve 66 which is connected to a source' of water supply, as a hot water supply by a pipe 67. o the T portion of the T 64 is secured by nipple 68 an elbow 69 which'is connected by ipe 70 to a valve 71 connected to'a source of water supply, as
a cold water supply, by pipe 72. p
Located at the rear of the apparatus and passin a connectingT 74 to the lower end of which is screwed a drain pipe 75 and screwed into the T portion 74 is one end of a pipe 76 which extends to a int under the tank 17 and is connected t ereto by means of an elbow 77. The stand i e 73 is connected another point defining the highest water level it is desired to maintain in the tank defined by the p'pe 79 extendi1$ between the tank and the standpipe 73. ithin the T 74 and above the upppr end of the drain.
75 is a valve seat 80 w ch cooperates with a disk valve bod 81 secured around the lower open end 0 a pipe or stem 82 which extends upwardly through thestandpipe 73 and has secured to-its upper end a knob or handle 83. This pipe 82 is provided with an elongated slot 84 in alinement with, or
\Rotatably mounted on the pipe For tube 86 which hassecure in the same horizontal plane as,.the connecting pipe 78 and with an elongated slot 85 in alinement with, or in the same horizontal plane as, the connecting pipe 79. 82 1s a pipe to its upper end a knurled ring 87 and by means of which the pipe or tube 86 may be rotated.
This pipe or tube 86 is provided with a slotc ma 88 whi be brought into registry with the elongate slot 84 and thus rov1de an exit for fluid downward throug the pipe 82 and into the drain even though t e valve 81 is on the valve seat 80, and by maintaining the slots 88 and 84 in registry, the water level in the tank is predetermined. Also the .pipe or tube 86 is provided with a slot 89 that may be brought into registry with the slot in .the pipe or tube 82 and preferably the position of the slots 89- and 85 with regard to the position of the slots 88 and 84 is such that the slots 89 and 85 will be in re istry when the slots 88 and 84 are out o registry thereby. making it possible to have the level of liquid in the tank comprised of the members 10, 14, and 16 maintained at the connecting tube 7 9,
From the above, it will be obvious that I may utilize the apparatus shown on the drawings and herein described as a dish washing machine which requires that the water he maintained at a-low level within the tank by filling the water chamber 17 and the lower part 10 of the tank 11 to a point determined by the tube 78 an may circulate such water b means of the impeller 20 of the pump t rough the manifold comprised of the pipes 55. and 56 and through the backboard 46 is a standpipe 73 provided at its lower end with through the upper spray cover manifold, including the spray chambers 52 and 53,-such pump, however, not being operable until the break point in the circuit of electric motor 33 is closed by the boss 58 on the member 49 engaging with the plunger of the control switch 57. It will also be apparent that I may utilize the apparatus as a substitute for the ordinary kitchen sink and may either maintain the level of fluid therein at the point predetermined by the pipe 78 and the slots 88 and 84 at a low point, such as .is found advisable when the device is used as a dish washing machine, or maintain it at a high level determined by the connectin pipe 79' and slots 89 and 85 by rotating t e tube or pipe 86 on the pipe 82 so as to throw the slots 88 and 84 out of registr and I ma empty the entire apparatus of uid by lifting the tube 82 by means of knob orhandle 83, .thus moving the valve 81 oil the valve seat 80.
While '1 have described the preferred form of down s ray, I may substitute for this preferred orm theform shown in detail in Fig. 7 wherein the sheet metal member 14 of the tank is secured to a modified form of ring 90, amodified form of cover 91 being employed and the modifiedform of ring 96 having an inwardly and downwardl extending lip 92 which partially shie ds a spray manifold 93 provided with a plurality of downwardly directed rforations 94 and this manifold is connecte with the pipe 43 by means of an elbow 95. This form of spray manifold is less liable toderangement and possible leakage than the form illus-;
trated'in the other figures on the drawings because of the fact that it is connected positively and permanently with the pipe 43 and does not depend for tight fitting on the biggie 47.
iIe I have shownand described the preferred embodiment of my invention somewhat in detail, it is to be understood that I may varythe sizeand arrangement of parts within wide limits without departing from the spirit of the invention.
I claim: a
