17 Claims. (Cl. 299-70) This invention relates to washingmachines and aims to provide a simple, inexpensive, compact and effective dishwashing machine particularly adapted for use in lunch counters, soda fountains and small restaurants, and for household use.

A particular object of the invention is to provide -for effective washing and rinsing of dishes with the use of a minimum quantity of hot water, which may be supplied under a comparatively low pressure.

This is a division of my copending application, Serial No. 266,258, filed March 31, 1928, for Washing machines.

In previous small dishwashing machines, it has been customary to use the same distributing system for the wash water and the rinse water.

This arrangement possesses the disadvantage of causing some contamination of'the rinse water by dirt contained in the wash water, and the further disadvantage that the reservoir of the machine must be completely filled twice to wash and rinse each batch of dishes. In larger dishwashing machines, it has been customary to provide a separate distributing system for the rinse water, but, in such machines, it has been necessary to have a sourceof clean hot water under a comparatively high pressure and to use a considerable quantity of such water in order to secure efiective rinsing. Both types of machines have, therefore, required the use of large quantities of clean hot water. To overcome this disadvantage, and to provide an effective machine requiring a very small quantity of clean hot water, I have invented means for utilizing energy developed in the distribution of pumped wash water to distribute rinse water supplied in small quantity and under low pressure and I have accomplished this without any contamination of the rinse water by the wash water.

An illustrative example of the means by which I have accomplished this important result will be given in connection with a detailed description of a small washing machine embodying this and other features of my invention and illustrated in the accompanying drawings in which:

The washing machine illustrated has a shallow tank 20 provided with a well 21, which serves as a reservoir. The tank 20 is covered by a casing consisting of a fixed cylindrically curved section 2 2, whose lower edge is turned around an external flange 22' at the upper edge of the tank 20, and a movable cylindrically curved section or cover 23. which is secured within the fixed I section 22 by pivots 24 lying on the common axis of the sections. A centrifugal pump '25 is mounted under the tank 20 on the inner side of the well 21. The pump is driven by an elec- 100 tric motor 26 carried by the pump casing 29. The central intake opening 27 of. the pump communicates with the well or reservoir 21 through an opening 28 in the side of the reservoir. The tangential discharge neck 30 of the involute 105 casing 29 of the pump extends through a central opening 31 in the bottom of the tank 20.

or other articles to be washed are supported in p a basket 111 above the distributor.

I will now describe in detail specific parts of the machine illustrated.

The combined distributor 32 (Figs. 1, 2, 3, 4) is in effect two distinct rotary distributors having their hubs integrally connected so that they are compelled to rotate as a unit. Thus the combined distributor has a hub 3'1 containing two distinct chambers 38, 39 separated by a horizontal wall 40. The hub has an open lower end 41 and a closed upper end 42. A'pair of hollow wash arms 43 extend radially outward from the lower part of the hub 37. The inner ends of these arms open into the lower chamber 38 of the hub. The wash arms have relatively large discharge nozzles 44 along their upper surfaces. The nozzles 44a nearest the ends of the arms are inclined so that liquid issuing from them tends to rotate the hub and arms by reaction. Two hollow rinse arms 45 extend outwardly from the upper part of the hub 3'1 with their inner ends in communication with the upper chamber 39 of the hub. These arms may contain elbows 46 so that the rinse arms 45 are parallel to the wash arms 43 but are spaced laterally therefrom. This is, however, not essential, as the rinse arms 45 may extend from the hub in any direction so long as they do not lie directly over the wash arms so as to obstruct the jets of liquid issuing from the wash arm nozzles 44. -The rinse arms 45 are provided on their upper surfaces with relatively small nozzles 47 so that forcible streams may be projected from them even when liquid is supplied to them at a slow rate and under low The outer rinse nozzles 470. are inclined in the same direction as the outer wash nozzles 44a.

Wash water from the pump 25 is supplied to the lower chamber 38 of the hub and thus to the wash arms 43, and rinse water from the pipe 51 is supplied to the upper chamber 39 of the hub and thus to the rinse arm 45. For this purpose the pump discharge/neck 36 is provided with an annular wash water passage 49 and a central rinse water passage 50 which extends through the pump casing 29. The rinse passage is in the pipe 51, located centrally in the discharge neck 30 and tangential to a circle concentric with the impeller or the pump, so that it does not retard the flow of the wash water. In the form illustrated, the lower end of this pipe is screwed in the upper part of a vertical threaded hole 52 extending through the pump casing 29. Rinse water is supplied to the lower end of the pipe 51 from the rinse supply pipe 54 whose end 55 is screwed into the outer portion of the threaded.

hole 52. The pipe 51 extends through and projecta beyond a closure 56 carried by a cylindrical extension threadedly connected to the upper end of the discharge neck 30 and forming an extenaion of the discharge neck 30 with the bottom wall of the washing machine casing clamped therebetween. The pipe 51 has a closure 5'] at its upper end. Just below the closure 56, the neck 30 is provided with lateral discharge openings 58, which are surrounded by the lower portion of the hub in which the lower chamber 38 is formed. The projecting portion of the pipe 51 is provided with lateral discharge openings 59 which are surrounded by the upper portion of the hub 37 and communicate with the upper chamber 39 inthe hub. The lower portion of the hub fits loosely around the upper end of the discharge neck 30 above and below the lateral openings 58 while. the top 42 of the hub and the horizontal wall 40 contain central holes fitting loosely around the projecting portion of the pipe 51 above and below the lateral openings 59.

The entire distributor 32 is suspended from a one-point bearing provided by a hardened ball 60,'seated in the closure 57 at the upper end of the rinse pipe 51. The upper end 42 of the hub is provided with a cage 61 having a flat vertically adjustable central bearing 62 resting on the ball 60. This bearing is so adjusted that clearances are provided between the hub and an external flange 63 on the neck 30 and the upper end 56 of the neck 30, so that the entire Y weight of the distributor is carried by the central bearing ball 60. The distributor bearing 62 is directly over, and well above, the center of gravity of the distributor, and the wash and rinse nozzles are each symmetrically located, so that there is substantially no friction between the hub and the sides of the neck 30 and rinse pipe 51. The suspension of the distributor from a central one-point bearing reduces friction to a minimum. It is so eifective that, if the distributor once be placed in rotation, it will continue to rotate for several minutes after the force which started its rotation has ceased to act.

The mounting of the hub is such that the whole distributor may be freely liftedfrom the discharge neck 30 and rinse pipe 51, and may be replaced in operative position by merely dropping the hub over the ends of the neck and rinse pipe. This greatly facilitates cleaning of the machine. In order that the distributor may safely be mounted in this freely removable manner, means are provided for preventing the creation, in the chambers of the hub, of unbalanced fluid pressures which would tend to blow the distributor off the ends of the discharge neck and rinse pipe. For this purpose, both chambers in the hub are provided with upper openings as large as their lower openings. far as the upper chamber 39 is concerned, this is accomplished by making the hole in the top 42 of thehub of the same diameter as that in the horizontal wall 40. To prevent an unbalanced upward pressure in the lower chamber 38, this chamber is provided at its top with an opening 64 fitting loosely around the closed upper end of the neck 30 and of the same diameter as the opening 65 at the lower end of the hub. The opening 64 leads to an intermediate. chamber 66 enclosed between the horizontal wall 40 of the hub and the closure 56 at the end of the discharge neck 30. Relief passages 67 extend'irom this chamber 66 through to the outer wall of the distributor to permit the escape of wash water as fast as it leaks into the chamber 66 through the opening 64 around closure 56, and thus to prevent building up liquid pressure against the lower side of the horizontal wall 40. The relief passages 67 are best shown in Fig. 4. These relief passages 6'7, which prevent the building up of pressure in the intermediate chamber 66, serve, not only to prevent blowing off of the distributor, but also to prevent the wash water from forcing its way into the upper chamber 39 of the hub around the rinse pipe 51 and thus contaminating the rinse water.

From the description of the operation of the machine given above, it will be understood that .wash water is first supplied'to the lower chamber 38 and wash arms 43 of the distributor through the annular passage 49, and that, thereafter, rinse water is supplied to the upper chamber 39 and the rinse arms 45 of the distributor through the rinse pipe 51. As the wash water is pumped, it may easily be supplied at a rapid rate and under considerable pressure; and, issuing in large streams through the inclined nozzles 44a, it sets the distributor into rotation and maintains its rotation during the washing operation. The distributor continues to rotate under its own momentum after the supply of wash water to it is stopped, and, by its rotation, serves to distribute the rinse water subsequently supplied to the rinse arms 45. It is therefore, not necessary to supply therinse water at a sufficient rate and under sufficient pressure to initiate the rotation of the distributor; and, in fact, the entire rinsing operation may be completed while the distributor is still rotating under the momentum given to it by the wash water. The inclination of the nozzles 4711 is, such as to tend to maintain the speed of rotation of the distributor during the rinsing operation. As the direction of the rinse liquid discharge is such that it does not set up reaction forces which oppose the rotation of the distributor, the momentum and kinetic energy of the distributor acquired during thewash liquid discharge is advantageously utilized in the distribution of the rinse liquid.

In order that the momentum of the distributor, obtained during the washing operation, may

be effectively utilized to distribute the rinse water, the common control handle 34 is so connected that, by a single movement of it, the supply of wash water to the distributor may be stopped and the supply of rinse water started.

The control mechanism is shown in detail in Figs. 6 to 16. The control handle 34 is at the end of an arm '70 fixed on the upper end of a vertical shaft '71 journalled in the bearing '72 secured to the side of the tank 20 near one corner of the tank (Figs. 1, 6, '7). A sleeve '73 keyed on the shaft '71 has two short arms '74 which cooperate with a stop '75 projecting from the side wall of the tank to limit the turning of the shaft '71 and the handle 34 (Figs. '7, 11). A sleeve '76 on the shaft '71 carries an arm '77 whose movements are utilized to actuate the switch 35 and the rinse .valve 36. For the former purpose, the arm has a depending part '78 positioned to engage a handle 79 of the switch 35. For-the latter purpose, the arm '77 is connected by a rod 80 to a lever 81 positioned to open the rinse valve 36 by depressing its stem 82.

The sleeve 76 and the arm '77 share the turning of the shaft '71 and may be rigidly connected thereto; but, in order to prevent injury to the switch 35 in case of an inaccurate adjustment of the parts, I prefer to provide a resilient connection between the arm '77 and the shaft 71. This is accomplished in the form shown by mounting the sleeve '76 loosely about the shaft and resiliently connecting this sleeve with the keyed sleeve '73 by means of two compression springs 83 reacting between the sides of the arm '7'? and two depending skirts 84 provided on a shelf 85 on the sleeve '73 (Figs. 8, 12).

The operation of the control mechanism which has just been described is best shown in the diagrammatic views, Figs. 13, 14, 15. Fig. 13 shows the neutral or inoperative position of the handle 34 and the operating mechanism, in which the switch 35 is held open by a spring 86 contained therein and the rinse valve 36 held closed by a spring contained therein. The handle is held in this position by a spring latch 8'7 (Fig. 10). Fig. 14 shows the handle 34 thrown to the left which turns the shaft '71 so as to cause the part '78 of the arm '77 to engage the switch handle '79 bringing the motor, pump, and wash arms into operation. The handle maybe left in this position as long as may be necessary to clean the dishes, as the switch spring 86 has not sufficient strength to turn the shaft '71. When the washing is completed, the handle 34 is thrown from its extreme left-hand position shown in Fig. 14, to its extreme righthand position, shown in Fig. 15. This movement of the handle 34 brings the part '78 of the arm '77 away from the switch handle '79, permitting the switch spring 86 to open .the switch, and thus stopping the motor and pump; and causes the arm '77, acting through the connecting rod 80, to tip the lever 81 to depress the stem 82 of the rinse valve 36, and open the rinse valve to supply rinse water to the rinse arms while the distributor is still rotating under its momentum. The rinsing takes only a few moments, during which time the handle 34 is held in the position shown in Fig. 15. As soon as the handle is released, the rinse valve spring and a spring 88 on the connecting rod 80, reacting between a disc 89 fixed on the rod and an abutment 90 on the tank, return the handle 34 to its neutral position shown in Fig. 13. It should be noted that these springs cannot turn the handle beyond its neutral position, for, at the time the handle reaches this position, the valve stem 82 is all the way out, and the thrust of the spring 88 is taken by a pin 91 in the connecting rod 80, so that'this spring no longer reacts against the bracket 90.
