for recirculating the water in the sink, with improved control means for controlling the recirculation and discharge of the water from vide a simpliiied form of dish washing mathe sink.

- Another object of the invention is to provide an improved orm'of spray head for directing the water against the surfaces of the dishes in the sink, to thoroughly cleanse the surfaces of all of the dishes.

Another object of the invention is to prochine of the type in'which water is recirculated and projected against the dishes.

A further object of the invention is to provide means for convertingv the dish washing machine into a clothes washing machine.

The invention possesses other advantageous features, some of which with the foregoin will be set forth at length inthe following escription where I shall outline in full that form of my. invention which I have selected for illustration in the drawings accompanying and forming part of the present specification. In said drawings I have shown one form of dish Washing machine embodying my invention, but it is to be understood that I do not limit m self to such formsince the invention as set orth in the claims, may be embodied in a, pluralityof forms.

Referring to said drawings:

Figure 1 is a bottom plan view of the mav chine of my invention.

Figure 2 is a vertical longitudinal section thru a dish washi'xig machine embodying my invention.

Figure 5 is a cross section taken on the line 5-5 of Figure 4.

Figure 6 is a top of plan view of the sink showing the clothes washing attachment of 'my invention in place. l

Figure 7 is a side elevation of the clothes washing attachment.

The dish washing machine of my invention comprises a dish receiving receptacle which is preferably a kitchen sink 2, of somewhat greater 4depth than the ordinary sink. The sink is supported on a frame 3 which extends downwardly to the floor and is usually installed in substantially the same manner as the usual kitchen sink. The plumbing lixtures associated withthe sink 'comprise the usual hot and cold water faucets arranged to discharge into the sink. The'sink isl also preferably provided adjacentA one corner of th'e bottom with a discharge outlet 12 thru which the water passes from the sink. Secured to the sink bottom and disposed below the dischar e outlet 12 is a valve body 13 having two out et passages 14 and 15. The' outlet passage 15 is connected to the drain pipe 1 6 which extends to the sewer connection and the outlet passage 14 is connected by the pipe 17 to the inlet side of the circulating pump 18.

Disposed withinthe valve body 13 is a semi-cylindrical rotary valve 19 which is mounted on the shaft 21 which extends to the front of the enclosing structure 22 where it is provided with a-handle 23. The valve 19 controls the discharge and the direction of the discharge of the water from the sink. In one position of the valve, for instance shown in Fi ure 3, the outlet passage 14 is closed and the slnk is placed,l in communication with the drain pipe 16. In another .position of the valve the outlet passage l5 is closed and the sink is placed in communication with the pump suction pipe 17. The valve 19 may also be turned, ii desirable, to cut off entirely the discharge of water from the sink, and this may be accomplished by turning the valve t0 close both the passages 14 and 15 or to close the passages 24 in the valve body which lead into the valve chamber. By the use of this valve, the water in the sink may either be recireulated and projected against the dishes in the sink or may be allowed to flow to waste, or may be retained in the sink.

The circulating pump'18 is mounted on the frame 3 and is preferably a pump of the centrifugal type. The pump housing is preferably provided with an integral conduit 25 extending from the center of the housing to the periphery thereof, so that the inletpipe 17 may be connected to the pump casting at the periphery thereof. The water passing thru the conduit 17 then passes thru the integral conduit 25 and enters the pump chamber at the center thereof. The pump is driven by a motor 26 which is mounted on the frame 3 and disposed below the sink 2 and which is connected to the pump impeller by the shaft 27. The shaft 27 is supported in the bearing hanger 28 and which is secured to the frame 3. The shaft also projects from the opposite side of the motor and secured to this opposite projection of the shaft is a pulley 3l for driving the iiexible shaft which may be used in combination with a rotary brush for cleaning the dishes or with other culinary utensils. Mounted on the frame 3 and spaced from the pulley 3l is a shaft 34 journalled in the bearing hanger 32 and provided on its end with a pulley 35 which is connected to the pulley 3l by the b elt 36. Secured to the shaft 34 is a iiexible shaft 37 which extends upwardly and which is available thru an aperture in the wall ofthe sink.

Referring to Figure 4, the wall of the sink 2 is provided with a bushing 38 in which is seated a nipple 39. The end of the flexible shaft 37 extends thru the nipple 39 and the head 41 of the shaft engages the nipple and is held against recession thereby. The nipple 39 is provided with a flange 42 to which the cap 43 is detachably secured. The nipple is normally covered by the cap and when it is desired to use the flexible shaft, the cap is removed and the flexible shaft drawn outwardly thru the nipple. The shaft is of sufficient length that it may be drawn thru the nipple for suilicient distance to permit it to be used for the usual culinary application.

The circulating pump 18 is connected on its discharge side to the pipe 45 which extends thru an end wall of the sink 2 and which is provided wit-hin the sink with an upright spray head 46 comprising a conduit having a plurality oftransverse slots 47 therein arranged in superposed relation. In order to secure a wide distribution of the water discharged from the slots 47, the successive suerposed slots are preferably inclined to the horizontal at increasing angles. Slipped over the upper end of the conduit head 46 is an elbow fitting 52 which is screwed to a horizontally disposed pipe 48 which lies adjacent the upper edge of the sink and which extends longitudinally in the sink to a point preferably past the center of the sink. On the end of the pipe 48 there is. a spray cap y49 having apertures or slots therein, from which the water discharges against the dishes which are disposed in the far end of the sink. By thus dividing the spray head into a plurality of discharging zones, the discharging water is distributed through the entire interior of the sink so that all of the dishes in the'sink are subjected to the washing action of the discharging water. During the dishwashing operation the sink is covered by a removable cover 51 which prevents the dischargeof any of the spraying water from the sink.

'lhe dishes are preferably supported in the sink by racks by which they are properly positioned and spaced to permit them to be thoroughly cleaned by the discharging streams of water. Disposed in the bottom of the sink is a rack 58 forsupporting the dishes and secured tothe horizontal pipe 48 is a rack 59 forsupporting cups and other utensils. bince the pipe 48'is secured to the rack 59, removal of this latter rack also causes removal of the pipe, thus giving free access into the sink for placing dishes in or removing them from the rack 58. v

Means are provided for -converting the dish washing machine into a clothes washing machine, and this means comprises a fitting which is adapted to be slipped down over the conduit head 46 after the horizontal pipe 48 and the connecting elbow 52 have been removed. rlhe fitting is shown in Figures 6 and 7 and comprises'a sleeve or pipe 53 adapt-v ed to slip down over the head 4 6. Connected to the pipe 53 are -two

pipes

54 and 55, the pipe 54 being short and extending transversely toward one side of the sink adjacent the head 46 and a pipe 55 being long and extending to the diagonal corner of the sink. Connected to the pipe 54 is a nozzle 456 for projecting water longitudinally in the sink` and connected to the pipe 55 are two nozzles 57 for projecting water longitudinally in the opposite direction at the opposite side of the sink.- rlhe recireulated water is thus discharged into the sink in such a way as to cause a swirling of the water with a. conse- 'quent washing of the clothes which are contained in the sink. The nozzles 56 and 57 I are preferably inclined downwardly to direct the issuing streams into the body of water contained in the sink sorthat an ebulution of the water in the sink is obtained.

I claim:

1. A dish washing machine adapted to be incorporated with astationary kitchen sink comprising a fixed pipe section extending upwardly in -said sink near one end thereof, a horizontal spray pipe having one end thereof removably mounted on the upper end of said pipe section and communicating therewith whereby said horizontal pipe is supported at one end only, said spray in said sink from and adjacent to onewall b elng adapted to overlie the interior o t e thereof, a removable, honxontal spray pipe sink when in operative position and to permounted solely on and in mit unobstructed access to the interior of with said ray head abovesaid a 5 the sink when removed, and a rack 'suptherein, an a rack supported solel by said 15 ported by said spray pipe. y horizontal spray pipe and remove. le there- 2.
