Specification of Letters Patent.

Patented May 2, 1922.

Application filed October 13, 1919. Serial No. 330,243.

To all whom it may concern:

Be it known that I, JULIUS FASSIO, a citizen of the United States, and a resident of the city and county of San Francisco and State of California, have invented a new and useful Dishwashing Machine, of which the following is a specification.

My invention relatesto improvements in dish-washing machines.

An object of the invention is to provide a combined dish-washing machine-and kitchen sink in which the dish washing machine elements are incorporated with the kitchen sink and its associated structures in such manner that the ordinary uses of the sink are not interfered with, comparatively little room is taken up and the machine elements are largely concealed from View.

Another object of the invention is to provide an eflicient, inexpensive and compact dish-washing machine of the character de scribed by means of which a large quantity of dishes, silverware, etc., may be thoroughly and expeditiously washed and cleansed.

The invention possesses other advantageous features, some of which, with the foregoing, will be set forth in the following description of the preferred form of my invention which is illustrated in the drawings ac companying and forming part of the specification. It is to be understood that I do not limit myself to the showing made by the said drawings and description. as I may adopt variations of the preferred form within the scope of my invention as set forth in the claims.

Referring to the drawings:

Figure 1 is a front elevation of my dishwashing machine showing it incorporated -with a kitchen sink drain board and cabinet unit, parts being broken away, removed and shown in section for the sake of clearness of illustration.

Figure 2 is an end elevation of the sink showing the arrangement of certain water feed pipes at one end of the sink, the other machlne elements being removed.

Figure 3 is a cross sectional View taken through the sink and showing the construction'of the sides thereof to provide for the injection of the Washing stream into the sink.

Figure 4. is a fragmentary sectional view taken on line 44 of Figure 3.

Figure 5 is an enlarged detail side elevation of the motor operating means and clutch for the pump and rotary cleaning brush.

Figure (3 is a cross sectional view taken through the drain board and cabinet of the sink showing the manner of housing and concealing the working elements of the machine.

Figure 7 is a longitudinal sectional view taken through the sink showing the dishes and silverware therein and in position to be washed.

Figure 8 is a fragmentary se-ctional'view taken through one corner of the sink showing the manner of connecting the channels with the pipes therefor.

In carrying out my invention I construct a kitchen sink so that jets of water may be sprayed orinjected from opposed sides thereof upon dishes placedin the sink and I preferably employ a cabinet-sink unit which has a drain board at one end and a cabinet under the board. A pump and operating means therefor are preferably arranged so as to be concealed in the cabinet. The pump is connected with the sink and with spray means on the sides of the sink so that water will run from the sink into the pump and be forced by the pump back into the sink in jets through the spray or jet means on the sides of the sink. I provide connections for the spray or jet means independent of the pump so that hot or coldwater or both hot and cold water may be sprayed, under the ordinary city or supply pipe pressure.

In the present embodiment of my invention there is provided a washing sink or receptacle 1 which is preferably in the form of a kitchen sink having the customary overhanging sides l'. The sink in this form has two drain boards 2 and 3 at the ends thereof under which boards are provided cabinets 4 and 5. Hot and cold water faucets 6 and 7 are mounted on the back board 8 of the sink. Legs 9 support the sink on the floor. A cover 10 having a handle 11 is mounted on and closes the sink during the dish-washing operations. The upper edge of the sink is provided with a flange 12 upon which the cover engages. When not using the sink in conjunction with the dishwashing machine the cover may be removed and placed to one side.

In order to incorporate the sink with the dish-washing machine, there is provided injecting or spraying means in the form of other and the pairs comprising the grooves 13 and 14 are disposed adjacent the upper edges of the sink whereas the pairs 15 and 16 are disposed adjacent the bottom of the sink.

I may have the grooves on one side extend partly into one end wall of the sink as at 19 for a purpose to be later described. The

portions 20 between the grooves of each pair are outwardly offset and plates. 21 and 22 are mounted on these portions 20 upon the upper and lowerpairs of grooves, respectively. Screws 23 hold the plates upon the portions 20 and flush with the side walls of the sink. The plates 21 close the grooves 13 and 14 and are provided with downwardly inclined openings 24 and 25 communicating with the groovesr13 and 14 respectively. The grooves 15 and 16 are closed by the plates 22 and these plates are provided with upwardly inclined openings 26 and 27 communicating with the grooves 15 and 16 respectively. The openings 24 and 25 will direct jets of water downwardly from both sides of the sink toward the lower edges of the sides. The openings 26 and 27 will direct water upwardly from both sides of thesink towards the upper edges of each side. Thus all of the jets or streams from the openings in the plates 21 and 22 intersect at about the center of the sink so that dishes to be washed when placed in the sink will have the jets of water thrown thereon from various angles and will be thoroughly washed.

Means is provided to conduct hot or cold water to certain of the grooves or channels and in this embodiment of the invention, to the channels 14 and 15 on each side wall. This means comprises hot and cold water pipes 28 and 29 respectively which are connected with sources of supply not shown and to a junction box or union member'30. This box 30 is located near one end of the sink and adjacent the center of said end. Pipes 31 and 32 extend from the box 30 towards the upper'edges of the side walls of the sink and communicate with the grooves or channels 14 on said side walls. Openings, 33 are formed through the sink soas to register with the grooves, and nipples 34 are carried by the sink at these openings so as to provide for the connection of thepipes 31 and 32.

Extending from the box 30 downwardly towards the lower edges of the side walls of the sink are pipes 35 and 36 which communicatewith the grooves or channels 15. Valves 37 and 38. are provided in the pipes 28 and 29 and hot or cold water or .walls whereas the grooves 15 will direct the jets downwardly from the side walls. Valve control handles 37 and 38' are preferably arranged on the front of the cabinet, so that the valves may be readily controlled.

In the dish washing operation, the larger particles of food and other material are scraped from the dishes and the latter are placed in the receptacle, the cover is then placed in position and hot or cold water or a mixture of both, but preferably hot water, is permitted to flow under pressure through the grooves 14 and 15 whence it discharges in jets against the dishes, washing therefrom the major portion of the material adhering thereto. This water with the removed material discharges through the drain pipe 40 which is preferably of about two inches in diameter and which has a large unrestricted opening into the sink. The major portion of the adhering matter is thus washed from the-dishes and discharges through the drain pipe 40 into the sewer. When this operation is completed, the valve 45 in the drain pipe is closed and means for projecting jets of soapy hot water against the dishes is brought into operation to thoroughly clean the dishes. This hot, soapy water is recirculated through the washing chamber for a suflicient time to thoroughly wash the dishes. The recirculating means includes an auxiliary drain pipe 41 which latter extends into the sink and opens above the bottom thereof so as to prevent large food particles from entering the pipe. The pipe 41 leads to a pump cylinder 42 of a pump 43 located beneath and adjacent to one end of the sink preferably in the cabinet 5. The pump may have one cylinder or a plurality of cylinders for producing a constant flow of the liquid. A valve 44 is arranged in the'drain pipe 41 and is connected to the valve 45 in the-pipe 40. These valves are connected by a link 46 having a handle 47 thereon and are arranged so that when the valve 44 is open the valve 45 will be closed and viceversa, thus one, movement of the handle 47 operates both valves. A drain pipe 48 leads from the bottom of cylinder 42 to drain pipe 40 for the purpose of draining-the pump cylinder when desired and this pipe 48 has a valve 48 therein near the cylinder connection thereof. Discharge pipes 49 and 50 lead from the lower end of the cylinder 42 upwardly to the adjacent end vided with an overflow drain pipe 55 which -ed'in the pipes 49 alid 50 to prevent aback flow of the soapy water to the pump on the up stroke of the piston. The sink is promay be connected to the sink in any suitable manner not shown and enters the main drain pipe 40 preferably below the valve 45 therein.

The pump 43 is provided with an open bottom piston 56 which is provided with a conical bottom valve 59 for controlling the flow of water through the piston. The valve 59 is secured to a vertically movable stem 60. so that it moves in time with the reciproconnecting the pump and the motor.

cation of the piston to control the flow of the water. Outlet ports 62 are provided at the lower end of the pump cylinder 42 to which the pipes 49 and 50 are connected. A connecting rod 63 is connected with the piston and with a crankshaft (34. The shaft 64 is jouriialled in a hollow cylinder head (35 and is operatively connected with a motor 66. The motor (36 is disposed to one side of the pump in the cabinet 5 upon a support (37. 'hen desired the motor may be eliminated and the piston reciprocated by a hand lever. as in the ordinary hand pump. The lower edge of the piston is tapered or bevelled inwardly, and the valve 59 is of less diameter than the cylinder, to provide for a ready flow of the water past the valve on the upstroke of the piston. By forming the valve conical in shape, material inthe circulating soapy water may not lodge-on the valve and prevent it from properly seating.

Means is provided for connecting and dis- The crank shaft 64 extends outwardly from one side of the cylinder head (35 and has a worm" wheel (38 fixed thereto. shaft69 journallcd on the support 67 carries a worm 70. which meshes with the worm wheel 68. ion one end of the shaft 69 a clutch member 7]. is fixed. The motor shaft 72 is provided with a clutch member 73 splined thereon and adapted to co-operate with the clutch member 71. A pivoted operating lever 78 is mounted on the support 67 and serves to operate the splined clutch member Fixed to the motor shaft is a worm 74 which drives a worm wheel 75 that is supported in a bracket 76. This wheel 75 is operatively' connected with a flexible shaft 77. The shaft 77 extends into the sink through an opening 78 in one end wall of the sink and on its free end carries a brush 79 which is rotated by the shaft and may be used for scrubbing pots and pans. The flexible shaft is sufficiently long to permit of-the brush being freely used in and around the sink when the sink is used as ordinarily. When and -38 as desired.

desired brushes or wheels of different character may be attached to the shaft'for polishing silver, sharpening knives or other nous basket orrack 81 within the sink and the cover 10 is then placed on and closes the sink. Hot or cold water or both may be run into the sink by operating the valves 37 lVater entering the junction box 30 will run through the pipes 31, 32, 35-and 36 into thechannels or grooves 14 and 15 on each side wall and will issue through the downwardly. and upwardly inclined opening 25 and 26 respectively in four rows of streams or jets. Theseijets will strike the dishes'with suflicient force to rinse them and wash the loose'food and adhering matter from the dishes. During this pie-washing or rinsing operation the valve 45 in the drain pipe 40 is opened whereas the valve 44 in the pi )e 41 is closed.

After the rinsing or initiai washing operation. and the water employedtherein has drained from the sink, the valve 45 is closed and the valve 44 inthe circulating pipe 41 opened. The valve 48' should also be closed. Hot water in sufiicient quantity to fill the circulating system, that is the pipe 41,.the pump 42 and thepipes 49 and 50 is then run into the sink and a suitable quan tity of soap or other washing material is added thereto. The pump is then placed in operation, and hotsoapy water is forced into the channels 13 and 16 whence it discharges in forceful jets against the dishes and subsequently drains back to the pump.

These jets are sufliciently forceful to thor- 7 .hot soapy water, thus directed from both sides, from above and below onto the dishes, they are thoroughly washed and cleansed in a short time. In order to maintain the soapy water in the circulating system hot, heating meanssucli as the gas burner 80 arranged below the pump cylinder, may be provided.

' After the dishes have been subjected to the hot soapy water for a suflicient time, the pump is stopped and the circulating liquid drains into the pump casing. The valve'44 is then closed. valve 45 is opened and clear hot water from the storage tank or heating system is turned into the channels 14 and 15, whence it discharges in jets against the dishes, thoroughlyremoving all of the washing liquid therefrom and keeping the dishes hot so that they may readily dry or be dried. The circulating liquid remaining in the pump may be drained to waste or may be eii iployed for washing subsequent batches of atlas.

The grooves 'at 19 extended into one end of the sink are adapted for cleaning silverware.

I may place the silverware in a separate cage 82 and place the cage at the corner adjacent the grooves at the point 19 so that jets of Water from both the side and said end will be directed onto the silverware.

The rotary brush 79 may be used to clean the sink after washing or to cleanse pots, pans, or very dirty or sticky dishes, etc. This brush may be driven independently of the pump by operating the clutch means to disconnect the pump from the motor.

I may cause the rinsing or pie-washing streams to be injected during the operation of the washing streams from the pump and thus add to the water streams to be directed upon the dishes.

I claim:

1. A sink having means on opposite side walls for directing streams of clear rinse water into the sink, means to supply water to the said means, a waste pipe for said sink, a pump, a suction pipe leading from the receptacle to the pump for supplying water to the pump, valves in said pipes, and a common connection for the valves holding the valves in such relation that when one is open the other is closed, and pipes connecting the pump to return spray means.
