HENRY R. MERSELES, SAID SIMMONS, BERT E. MERSELES.

Application filed May 5,

To all whom it may concern:

Be it known that we, HERBERT E. MER- BELES, HENRY R. Mnnsnmas, CHARLES F. SIMMONS, and PAUL H. ENGEL, citizens of the United States, residing, respectively, at Bronxville, county ofv \Vestchester, and State of New York; Bronxville, county of Westchester, and State of New York; New- Rochelle, county of Vestchester, and State of New York; and New York city, county of Bronx, and State of New York, have invented certain new and useful Improvements in \Vashing Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to washing machines and has for an object to provide a small, simple and compact mechanism which will adequately clean dishes and other articles.

Dish washing machines heretofore used have customarily included acomparatively large tank or similar receptacle and various different moving parts secured to different parts of the tank or the framework support ing the tank so that it has been necessary to provide a special tank which formed a part of the machine and to attach various different parts of the working mechanism in different related positions upon the tank and its framework in order to assemble the machine. The present invention provides a complete device including the dish washing mec anism for directing water against the dishes and mechanism for actuating the dish washing mechanism all mountedcompactly upon a single rigid frame. The actuating mechanism of the device is automotive, that is, it does not require a mechanical connection to an outside driving means. This device we have termed a dish washing unit.

A dish washing unit made in accordance with the invention may be completely assembled with all its parts in proper operative relation and thereafter applied to any desired form of receptacle, such as a tank, sink, or basin. In the form which we consider most desirable, the frame of the dish washing unit includes a part which is adapted to form aclosure for an opening in the bottom of the receptacle to which the unit is applied. It is thus possible to apply NEW YORK, N. Y.; SAID AND SAID ENGEL ASSIGNORS TO SAID HER- wasmne MACHINE.

1921. Serial No. 467,046.

the completely assembled unit to any receptacle provided with a suitable opening in its bottom by merely placing the unit in this opening and securing it to the bottom of the receptacle about the edge of the opening.

In order that the invention may clearly be understood, we will describe in detail the specific embodiments of it which are illustrated in the accompanying drawings, in which Fig. 1 is a side elevation partly in section of a complete dish washing machine incorporating the dish washing unit;

Fig. 2 is a horizontal section on the line 22 of Fig. 1;

Fig. 3 is an enlarged vertical section of the lower portion of the dish washing machine of Fig. 1 showing the construction of the dish washing unit;

Fig. 4: is a horizontal section on the line 4.4 of Fig. 3 showing the construction of the pump;

Fig. 5 is an elevation partly in section showing the application of the dish washing unit. to a well provided at the side of a sink and below the drain board of the sink;

Fig. 6 is a perspective view showing a removable attachment for sinks incorporating the dish washing unit;

Fig. 7 is an elevation partly in section showing the application of the dish washing unit to a sink; and

Fig. 8 is aplan view of the arrangement shown in Fig. 7 with the partof the dish washing mechanism above the bottom of the sink removed.

The dish washing machine shown in Figs. 1 to 4 comprises a tank 10 which may be constructed of sheet metal or other suitable material. The tank 10 is supported upon legs 11. The inner surface of the tank 10 is provided with an inwardly projecting bead 12, or other suitable means, for supporting the rack 13 in which the dishes or other articles to be washed are placed. The bottom 14: of the tank 10 is preferably downwardly inclined towards its center as shown in Fig. 3. At the center of the bottom 14 is a circular opening 15.

The dish washing unit 20 is inserted in the opening 15 and secured to the bottom of the tank about the periphery of the opening, no other support for it being necessary. s hereinafter explained, the frame of the unit is formed to provide a closure for the 0 en'- I stationary part of the dish washing mecha nism comprises a pump body 22. The upper part-of the'pump body 22 forms a casing 23 providing a chamber for a rotary impeller while the bottom 24 of the pump body 22 is spaced from the casing 23 and forms a closure for the opening 15 in the bottom of the tank 10. Three radial fins 25 connect the casing 23 of the pump body with the bottom 24 of the body. The space between the fins 25 and between the bottom 24 and the lower wall 23' of the casing 23 forms inlet passages communicating with the tank 10 and leading from the side of the pump body to points near the middle of the pump body. These inlet passages have wide, low openings at their outer ends and their cross-section gradually decreases toward their inner ends. From the center of the top of the casing 23 projects a neck 26 forming an upwardly di-' rected discharge opening. The motor casing 30 is rigidly secured to the lower side of the bottom 24 of the pump body 22. In the form .illustrated, the motor casing is provided with three upwardly extending arms 31, which are preferably made integral with the upper part of the casing 30. The outer ends of the arms 31 are connected by a ring 32 preferably made integral with the arms, and this ring is secured by screws 33 to the bottom 24 of the pump body 22. The top or upper end of the motor casing 30 is imperforate except for the shaft opening at its center.

In the rigid frame 21 of the unit is rotatably mounted a vertical shaft 40 which is common to the motor and the pump of the Washing mechanism. The shaft '40 is supported upon a thrust bearing 41 located in a boss 46 projecting downward from the lower end of the motor casing 30. A shoulder 42 on the shaft 40 forms the upper race 43 of the bearing, while the lower race 44 of the bearing is formed by the upper end of a threaded sleeve 45 which is screwed into t e boss 46. lit is apparent that the arrangement described affords means for the vertical adjustment of the shaft 40. A bearing 47 is provided for the shaft 40 in a boss 48 projecting from the upper-end of the motor casing 30. The shaft 40 extends upwardly from this hearing into the pump body 22- through a centrally located hole 50 in the bottom 24 of the pump body. The upper memes portion of the hole 50 may form an additional bearing 51- for the shaft 40 and" the lower portion of this hole is of larger diameter than the shaft, afi'ording space forastutfing box 52. The packing 53 of the stufiing box 52 is compressed by a threaded'sleeve 54 screwed into the lower portion of the hole 50.

A deflecting flange 55 is mounted upon the shaft 40 just above the top of the boss 48 of the motor casing 30. This. flange serves to direct any Water which may leak through the stuiiing box 52 outwardly from the shaftso that it falls upon the imperforate top of the motor casing 30 and is thus prevented from entering the motor.v

An impeller is fixedly mounted upon the upper end of the shaft 40 within the chamber provided by the casing 23. From the upper end of the hub 61 of the impeller 60 extends a disc-shaped flange 62 from which depend spiral blades 63 preferably made integral with the flange. Similar fixed spiral blades 64 are secured to the top of the casing 23 above the disc-shaped flange 62 and are preferably cast integrally with the top of the casing. A clearance is provided between the bottom of the impeller hub 61 that the top of its flange 62 just clears the lower edge of the fixed blades 64 while the lower edge of the impeller'blad-es 63 just clears the lower wall 23 of the casing 23. The threaded sleeve 45 is also used to take up'for wear upon the thrust bearing41 so as to prevent such wear from causing the shaft 40 to drop sufliciently to bring the impeller blades 63 into contact with the lower wall 23 of the casing 23.

A bushing is removably secured in the discharge opening formed by the neck 26 of thepump body 22, by a screw 71 which passes through a tapped hole in the side of the neck 26 and enters an annular recess 7 2 in the bushing 70. A hollow hub 73 is rotatably mounted in the bushing 70. The hub 73 is provided at its lower end with an external flange 74 which engages under the lower end of the bushing 70 and thus prevents the hub from moving upwardly in the bushing.

Hollow spray arms

75 and 76 extend radially from the hollow hub 73 above the top of the neck 26. The

spray arms

75, 76 are provided along their upper sides with upwardly directed

discharge orifices

77, 78, 79, 80 and 81. One or more of the discharge orifices are inclined so that the reaction of water discharged through them causes a rotation of the hub 73 and

arms

75, 76. In the form shown in the drawings, the two

discharge orifices

78, 81 at the ends of the arms are thus inclined. It should be noted that the distance of the discharge orifice 77 of the arm 75 from the axis of the hub 73 is greater than the distance of the discharge orifice 79 of the arm 76 from the axis and less than the distance of the orifice 80 from the axis. Consequently, when the arms rotate, the orifice 77 moves in a circle between the circles in which the

orifices

79 and 80 move. If desired, the

end orifices

78, 81 may be located at different distances from the axis of the hub so as to rotate in different circles. Although in the apparatus illustrated the

spray arms

75, 76 are formed of pieces of metal separate from the hub 73, this is not essential, and the use of the word hub and the word arms in the claims should not be understood to imply that the hub is necessarily separate from the arms, for it may be merely the axial portion of an integral member which forms both the arms and the hub.

The rigid frame 21 of the unit is formed to provide an annular external flange which in the form illustrated consists of a flat ring 85 secured to a flange 86 surrounding the bottom 24 of the pump body and to the ring 32 of a motor casing by bolts 87. After the dish washing unit as described has been completely assembled it is placed in the opening from above and secured in position by attaching the flange 85 to the bottom of the tank about the periphery of the opening 15 by soldering, bolting or otherwise. If desired, the ring 85 may be secured to the bottom of the tank before it is attached to theframe 21 of the unit. In this case the ring 85 becomes in efl'ect a portion of the bottom of the tank to which the frame of the unit is attached by bolting the flange 86 to the ring 85. In either case after the unit has been secured in position the portion 24 of the frame 21 of the unit forms a. closure for the opening in the bottom of the tank.

The closure 24 is provided with an eccentric opening 90 which serves as a drain opening for the tank and may also be used for filling the tank. In the form shown in Fig. 3 the opening 90 is connected by an elbow pipe 91 through a three-way valve 92 with a pipe 93 leading from a source of hot water and a pipe 94: leading to a drain.

In the tank 10 above the intake openings of the pump body 22 and below the

spray arms

75, 76 is placed a screen or strainer 95. The screen 95 preferably consists of two semi-circular portions as indicated in Fig. 2 which may be removed from the tank when the

spray arms

75, 76 occupy a position at right angles to that shown in Fig. 2.

In using the dish washing machine described, a rack 13 containing soiled dishes or other articles to be washed is placed in the tank 10 upon the head 12. Hot water is ,or washing powder is admitted to the tank through the opening 90 by placing this opening in communication with the supply pipe 93 through the threeway valve 92. Sufficient water is admitted to submerge the inlet openings between the fins of the pump body. The valve 92 is closed before the water reaches the level of the

arms

75, 76 and preferably when the water is a little below the screen 95. Soap then preferably added to the water in the tank. The motor is then operated, rotating the vertical shaft 40. This rotates the impeller which is mounted upon the shaft 40. The impeller blades 63 draw water from the tank through the inlet passages between the fins 25 and throw it outwardly in the casing 23, while giving it a whirling motion. Owing to the form of the inlet passages air is not drawn into the pump even when the water in the tank is so shallow that it just submerges the outer ends of these passages. The stationary blades 64 direct the water whirling about in the casing 23 to the center of the casing whence it is discharged upwardly through the neck 26. into thehub 73. It passes through the hub into the spray arms 7 5, 76 and out through the upwardly directed discharge orifices 77 78, 79, 80, and 81 of the spray arms in fan-shaped sprays. The reaction of the water discharged through the

inclined orifices

78, 81 causes the hub and arms to rotate. In this rotation the discharge orifices 77, 79 and 80 move in diifer' ent circles so that water is projected upwardly against all parts of the dishes con-- tained in the rack 13, serving thoroughly to cleanse them in a very short time. During this operation, the solid matter removed from the dishes is caught upon the screen 95 and thus prevented from entering the pump casing. Upon the completion of the washing, the water in the tank is withdrawn through the opening 90 by placing this opening in communication with the drain pipe 94 through the three-way valve 92. Clean water may then be admitted as before from the pipe 93 and the operation repeated to rinse the dishes and remove all soapy water from them.

The dish' washing machine shown in Figs. 1. to 4, which has been described, illustrates the application of the new automotive dish washing unit to a tank designed to be used for dish washing only. While the compactness of the dish washing unit and the fact that it may be completely assembled before being applied to the tank makes the dish washing machine described simpler and more economical to manufacture than dish washing machines heretofore made, the utility of this compact dish washing unit is still more evident in connection with the application of it to other types of receptacles.

In Fig. 5 is shown a kitchen sink 100 whichis divided by an integral partition 101 intoa shallow portion 102 and a deep porton 103. The deep portion 103 has at its bottom an opening about the periphery of which the dish washing unit is secured. The cover 104 of the deep portion 103 ofthe sink serves as a drain board for the shallow portion 102 of the sink. As sinks are customarily provided at one side with such a drain board, the location of the dish washing unit under the drain board places it out of the way and in a space which would otherwise not be used. In the form shown in Fig. 5, the opening in the portion of the frame of the unit which forms a closure for the opening 15' in the bottom of the deep portion 103 in the sink is connected through a three-way valve 92 to the drain pipe 105 of the shallow portion 102 of the sink and to the pipe 106 which supplies the hot water faucet 107 above the shallow portion 102 of the sink. If desired, however, the opening in the frame of the unit may be connected only to the drain and water may be introduced into the deep portion 103 of the sink through an aperture in the partition 101 which may be provided with a removable closure;

Fig. 6 shows the dish washing unit 20 ap plied to a cylindrical tank 10 the upper edge of which is secured about the periphery of an opening in a board 120, preferably made of sheet metal, so that the tank is suspended from the board. The board 120 is provided with legs 122 and is adapted to be laced at the side of a kitchen sink 121.

he inner end of the board 120 rests upon the edge of the sink. 121 and is supported thereby while the outer end of the board is supported by the legs 122. The cylindrical tank 10' is in general similar to the tank 10 shown in Fig. 1 and the washing unit 20 is mounted in its bottom in the same way. A drain board 123 is hinged to the board 120. This drain board dish washing attachment occupies but a small space and may be applied to any sink without alteration'thereof, it being merely necessary to make the pipe connections between the dish washing unit and the drain pipe and hot water pipe of the sink. The washing unit below the drain board is in convenient position for use whenever desired, it being merely necessary to raise the drain board 123 to obtain access to it. When the washing mechanism is not in; use the drain board 123 lies upon the board 120 covering the tank 10', and is in position to serve as a drain board for the sink 121.

Figs. 7 and 8 show another application of the dish washing unit 20 to a kitchen sink. In this form, the sink 109 is of the usual size and sha e except that it is provided at the center 0% its bottom with a circular well 110 at the bottom of which is an opening 15. It is about the periphery of this opening that the legs of the rack and the cover.

' raaaree the frame 21 or the dish washingunit at a secured. The depth of the well 110 is such that while the entire pump body 22 is below the bottom of the sink 109, the arms 75,- 76

and serve to hold the rack above

thearms

75, 70. A removable dome-shaped cover 112 which may be either squareor circular in W6 cross-section is placed over the dish rack and arms to confine the water projected upwardly from the arms. The bottom of the sink 109 may be provided with a rib 114 to positli gn e screen 95 is at the level of the bottom of the sink 109. The drain opening in the unit frame may be connected to the drain pipe of the sink through a valve 113. It is not necessary to connect this opening with a source of hot water as'the well 110 may be filled with hot water from the hot water faucet 115 of the sink. This is done before the cover 112 is placed in position.

When it is desired to use the sink 109 independently of the dish washing unit, the

cover 112 and the rack 13' are removed from the sink. The screen 95 may then be removed so that the screw 71 ma be reached and loosened, permitting the wlthdrawal of the bushing 70 from the discharge neck 20 so' that the arms, hub and hearing may be lifted out. The screen 95 is then replaced and a plu or cap 116 laced in the discharge neck 26 %Fig. 8). hen this has been done no portion of the washing mechanism remains within the sink. 109 so that the sink may be used in the ordinary manner. u

The combined sink and dish washing apparatus shown in Figs. 5 to 8 forms the subject matter of our divisional application filed January 19, 1924:, Serial No. 687,180,
