ROBERT W. STEED, OF NEW YORK, N. Y.

DISH-WASHING MACHINE.

Specification of Letters Patent.

Patented Apr. 25, 1916.

Original application filed January 23, 1912, Serial No. 672,877. Divided and this application filed November 22, 1913. Serial No. 802,516.

To all whom, it may concern:

Be it known that I, ROBERT W. S'rnno, a citizen of the-United States, residing at borough of Brooklyn, in the city of New York and State of New York, have invented certain new and useful Improvements in Dish-Washing Machines, of which the following is a specification.

My present invention relates to dish washing machines, the object thereof being to provide a machine particularly adapted for domestic use in homes and small kitchens,

although it is equally well calculated to serve for efficient use on a. larger scale; and it consists essentially in a centrifugal, turbine or rotary pumping means whereby Water is lifted vertically to a point where it can be projected laterally against the dishes and other articles requiring cleansing.

In the annexed drawings illustrating my invention, Figure 1 is a perspective view of my improved dish washing machine, a por; tion of the tank being broken away to expose toview the internal mechanism. Fig. 2 is an enlarged vertical section of the operative mechanical parts 'of my improved dish washing machine, including more particularly thepumping mechanism. Fig. 3 is a sectional plan view on the

line

3, 3 of Fig. 2. Fig. 4 is a sectional plan view on the line appearance of the diffusing vanes andv the blades of the water pump. Fig. 5 is an enlarged detail section of a broken awayvportion of certain of the diffusing vanes and the pump blades, for the-purpose of showing their relative location as well as their shape; the section of Fig; 5 being on the line 5, 5, of Fig. 4. Fig. 6' is a sectional view on the line 6, 6 of Fig. 3. f 1

Similar charadters of' reference designate correspondingiparts throughout all the different figures of the drawings a In carrying my invention into practical ef feet I provide a main tank 1 of suitable size for containing the dishes and other articles to be washed,=as well as the main parts oftlie operative mechanism, which tank is to be considered as the main washing tank. I utilize an elevated water-heating tank 4, which is supported in any desirablemanner, and has the function of heating 9.

proper quantity of water which can be supplied to, the washing mechanism. This water'tank 4 hasan outlet-pipe 10 providedupper ends of said

pi

4, 4, of Fig. 2 and indicates especially the with a cock 11, which pipe 10 runs downwardly and connects with a pipe 12, see Figs. 1 and 2, which leads to the interior of the tank 1 and connects with other parts of the mechanism there. Under the water tank 4 are gas ets 5 so that in this way the water can eas1ly be heated. The pipe 12 enters a stationary casting 15 provided with a downwardly-projecting outlet nozzle 18 which delivers through a circular opening 19 into the upper revolving circular casting 24. Two

vertical pipes

20 and 21 placed diametrlcally opposite to each other have their up per ends fixed securely into the upper revolving casting 24, and their lower ends fixedly held by a base plate 23. The upper hollow casting 24 is provided with horizontally-projecting outlet pipes 22;. any suit able number of them. The pipe 20 is furnished in its lower half with a. series of'horizontal projecting pipes 25, while the opposite pipe 21 is provided in its upper half with a similar series of horizontal projecting pipes 26. hThus it will be seenthat the pipes 25 and t e pipes 26 project in opposite directions. While the lower ends of the

vertical pipes

20 and 21 are closed and securely held by the horizontal casting 23, the communicate with the interior of the ho ow casting 24 and receive a hot water supply therefrom which passes downwardly through said

vertical pipes

20 and 21 and finds outlet through the end with a circular dlSk'Ol casting 28 securely seated therein and connected thereto, said disk 28 forming partof the bottom of the casting head 24. This circular casting 28 isprovided with an upwardly projecting shaft 13 on which is a grooved pulley '14. A belt 29 passes around this pulley and to a.

small electric .or other motor 31. Thus itwill be seen that -I provide means whereby the shaft 13 is drive cylinder 16 and the casting 24 and

pipes

20 and 21 are jointly caused to revolve.

Continuing my description of the discharge cylinder 16, which is really in fact a hollow shaft, I desire to point out that it is' provided at intervalswith outwardly-proipes 20 and 21 is a water downwardly n, and consequently the jecting pipes 17 similar to the pipes and 26. These pipes are located at any suitable points and are more or less staggered, for eXample,-or so situated that the water ejected through them from the interior of the cylinder 16 may be cast in all directions throughout the interior of the tank 1, see Fig. 1. The branch pipes 17 are provided each with a small perforation, as at 27, to admit air to break the vacuum and thus permit the water to rise higher in pipe 16 and flow out of all the pipes 17, in the whole series to the top of pipe 16. \Vithout the perforations 27 the head-of the outflowing water at the ends of pipes 16 can be so great as to prevent the water rising more than a short distance in pipe "16. a

*The' lowerehd'of the: cylinder 16 is attached to a conical or. bell-shaped casing 35, having also a cylindricalpart, the lower end of which is'securely fastened to a pump impeller 38, which is clearly shown in section, *in' Fig. 2,'and theblades' of which, 39, are.

P 3 f serves to enable 'thejwat more efliciently when the 1m The reason for this is, that the rapidly-rotating some other; 21

33 atthe bottom of tank 1.

casing 35 causes a rapid swirling motion in the water around it, and in the absence of the barrel 31 the water would not flow down through the receptacle 33 to the suction of the pump, but its course would be interfered .with by the revolving Water around casing It will be evident that, with the difl'using vanes carried by the shaft 37, and thereby held in a stationary position, when impeller 38 with its series of turbine blades rotates, the Water in the receptacle 33 will be pumped up and'discharged into the cylinder 16, and will be carried upward through said cylinder until it reaches the lateral outlet pipes 17, through which it will be passed and projected in a plurality of streams in different directions thewvater allowed to pass down into the hollowcasting 2-l and the vertical pipes 20 and emerging thence to fill the receptacle As soon as the requisite quantity of water has been supried-from the tank 4 to the tank 1 the valve The motor 31 will then ndthe discharge pipe 16; therefore, as soon sqthe avater fills the pipe 16 it will be thrownflout of the branches 17 in a whirling spray, which will dash through the different f parts ofthe tank 1 and will impinge briskly uponthe dishes which have been placed the tank, andwill then fall back into he receptacle 33 at the base of the tank, and be repumped as often as desired. While he motor 31 continues to revolve, the water ,e a cted on by the impeller 38 and aused to be driven upwardly through the d ffusing vanes 40 and lifted through the jvifcylinder 16 until it reaches the varius projecting staggered horizontal outlet Yes 17 through which the water will be "mjeetea in a plurality of streams which 11 'ke against the dishes and effec- V perform a washing operation thereof. will be continued until the Water in recepftaole 33 has been pumped by the cenl ugal pumping mechanism and delivered pon the articles to be Washed. Of course e water will flow back again and be repumped, usually a number of times, and this operation will be continued until the dishes are properly cleaned. The motor 31 will then be stopped and by either using the valve 43 or the faucet 44, the greasy water and other contents of the tank and the receptacle 33 can be withdrawn, after which the valve or faucet will again be closed. Then the motor 31 will be again started and the

vertical pipes

20 and 21 set in revolution (as well as the connected parts), and

the clean hot rinsing water coming from tank 4 down through

pipes

20 and 21 will be thrown out through

pipes

25 and 26, and a supply of clean hot water directed against the dishes which will enable them to be rinsed off. It will be found that by these operations the tableware will be efl'ectually cleaned and rinsed and then dried, and everything will take place easily and con veniently with a small number of manual operations and with very little attention on the part of the user.

Many changeslin the precise construction and arrangement of the various parts may be made without exceeding the scope of the invention.

I do not in this case claim the combination of the tank in which the dishes are supported, a rotatable vertically disposed pipe carrying a series of lateral outlets arranged at different levels, and means for su lying the said pipe with water from outside the tank; nor the said elements when further combined with a rotary pump, of-

any suitable type, communicating with the tank, a pipe to which the pump delivers and from, which the water is discharged against the dishes, and means for revolving the pump and the said vertically disposed pipe; nor the rotary member having two sets of water delivery conduits, one communicating with a water supply external to the tank, and the other receiving water from a'pump that is supplied from the tank; as such subjects matter are claimed in my former Letters Patent No. 1,090,420, dated March 17, 1914, of which the present application is a division.

What I claim is 1. A centrifugal pumping means comprising a vertical cylinder with discharge nozzles, an enlarged casing fixed to the lower end of the said cylinder, a second cylinder surrounding said casing to prevent a whirling motion of the water, an impeller at the lower end of the said casing and fixed thereto, means for revolving the casing and im peller, and a set of stationarily supported diffusion vanes located within the said casing above the impeller.

2. The combination of a tank, a Well into which the tank is adapted to drain, a revolving cylinder closed at its upper end and provided with a series of discharge nozzles, a casing fixed to the lower end of the said revolving cylinder and located within the said well, an impeller at the lower end of the casing and fixed thereto, and stationarily supported diffusion vanes within the casing above the impeller, together with a stationary shaft on which the impeller is mounted, said shaft constituting a support for the impeller and the casing and likewise supporting the diffusion vanes.

3. The combination of a tank, a well into which the tank is adapted todrain, a revolving cylinder closed at its upper end and provided with a series of discharge nozzles, a casing fixed to the lower end of the said revolving cylinder. and located within the said well, an impeller at the lower end of the casing and fixed thereto, stationarily supported diffusion vanes within the casing above the impeller, and a cylinder located in the well surrounding the revolving casing and close thereto and freely opening into the Well, the said cylinder serving to prevent a whirling motion being imparted to the main body of water in the well.

4. A centrifugal pumping and water-distributing device, comprising a cylinder closed at its upper end and provided with water discharge nozzles, a casing fixed to the lower end of the cylinder, an impeller at the lower end of the casing and fixed thereto, a support for the upper end of the cylinder, a stationary shaft on which the impeller is mounted constituting a support for the impeller and casing, such supports permitting the cylinder, casing and impeller to freely rotate, and diffusion vanes supported by the said stationary shaft and arranged within the casing above the impeller.
