Application ineaivovember 19, 1921; serial No. 516,418. Y
To all whom t may concern.'
Be it known that I, HARRY'ROSENBAUM, a citizen of the United States, residn at New York, county of New York, and tate of New York, have invented certain new and useful Improvements in Dishwashing Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the'invention, such as will enable others skilled in the art to which it appertains to make and use the same. v
This invention relates to dish washing apparatus; and it relatesv more particularly to dish ywashingI apparatus of the type wherein a rotatable spray device Asuitably mounted within a Vcontainer for dishesdirects a plurality ofstreams ot' water upon the dishes. Av dish washer of the general type here in question is disclosed in my Patent No. 1,386,734 granted August 9, 1921; and the present invention involves certain novel features of construction iny the nature of improvements upon that type of construction, as well as others 'ofl more general application, as will more fully hereinafter appear. Some of the principles underlying the present invention are disclosed broadly in my prior copendingapplication, Serial. No. 497,146, filed August 31, 1921, of which the present application isa continuation in part. i
Generally stated, .the principal object ofV the present invention is to render stillfmore convenient, dependable'and effective in op eration dish washers of the1 character above mentioned; and especially` to provide appa-V ratus of thiskind Whichis certain in its action and yet requires little or no skilly or care to operate, and which is therefore particularly well adapted for ordinary household use.
A flirt erl Objectis to` provide a dish washer co truction in whichthe mounting of the moving parts is of such' nature and arrangement that freedom of movementof such parts is always ensured even under conditions of.. rough handling, whereby` not only is theA operating power required re duced toa minimum, 'but also theemploy- -mentof relatively light material` especially for the ldishreceptacle'or tank. is made feasibn. c i- Anotherobjectis to provide a. censtrucf the cover removed;
tion in which the parts `constituting the `water-supp1y means andthe revolublespray means can be assembled with each other'and with the dish receptacle easily4 and quickly to g'ive a resultant strong and sutliciently rigid construction, andA can as readily; be
'disassembled for cleaning or other purposes.
Still another object ofv the invention y1s to provide a spraying ydevicethatdi'rects cleansing streams or jetsV against the dishes in a more thorough, systematic and effective l manner than has been possible heretoforen dish washing machines of this general` type. With the foregoing general objects in view, as well as some others that will be 0b.-
vious as the descriptionY proceedsjthe .invention comprises `the features,` details of `construction and combinations ofvparts which will first be described in connection with an illustrative embodiment of the broad principles of the invention in'anespecially desirable specitic construction, and' will then be more particularly pointed out inthe appended claims.
The accompanying drawings forming a part hereof show one particularly advantageous. practical form which thebroad invention may take. In .these drawings,
lFig. 1 is a vertical transverse section through the dish washer on theline 1-1 of Fig. 2 is a plan viewlof the washer with Fig. 3 is a central longitudinal section, or a larger scale, of the spray device and associated parts, showing' details of eonstrucf tion and arrangement; p
Fig. 4 is a transverse sectional detail -on the line 4--4 of Fig. 3; and
Fig. 5 is a long g'itudinal section of the tubular spray device on the line 5-'-5 of Fig. 4. Y
Referring to the drawings` designates generally a dish receptacle or container,
closed by a removable cover 11. In the present example, the. dish receptacle or tank is rectangular in shape. having two pairs of opposed vertical parallel walls; 12;-12 and 13pm, and a bottom 14 provided with a suitable drain outlet 15 of any suitable form and convenient location. Extending horizontally between the walls 13-13 is a tubular spray device 16, rotatably carried upon after, said spray device is of the self-proplace to `ture of t e combined supporting and suppelled reaction-jet type, so that perfect freedom of movement on its bearings is of rime importance. Most desirably, and as s own in the present example, said supporting means comprises the water-supply pipe 17,
perforated as indicated at 18 for flow of lwater into said spray device and adapted to berigidly but removably connected at its opposite ends to said walls 13-13. Such connection may be variously effected, but the construction illustrated is especially serviceable and convenient. The ends of the supply tube 17 are threaded, as shown, one end screwing into a tubular fitting 19, which provides a water-supply inlet and which will be described in greater detail resently, and which has its flange 19a tight y secured by rivets 20, or otherwise, to one of said walls 13, the-boss 21 of saidlitting projecting a short distance inside the wall through an opening therein. On the other threaded end of tube 17 is a supporting and closure member 22', in the nature of a cap nut, having a tubular portionA 23 that projects through an opening 24 in that wall 13 of the receptacle a distance limited by the stop- 'flange 25, and screws on to said other end of the supply tube 17. The tubular portion 23 of the cap or closure is externally threaded also to take a locking or clamping n ut 26, by means of which the wall 13 can be firmly clamped between said clamping nut vand the flange 25 of lthe cap nut to lock the parts in place. 7
It will be seen that this arrangement provides for holding the opposing walls 13-13 rigidly in predetermined spaced relation, at least in the location adjacent the ends ot' the rotatable spray tube 16. This latter, of which preferably only the apertured end walls 27, 28, bear upon the stationary supply tube, is best capable of slight longitudinal play between boss 21 and portion 23 of the cap as indicated. Obviously, even if the Walls of the dish receptacle be made of relatively thin sheet metal, warping and bending of the walls through careless handling or for other reasons cannot operate to bind or eramp the rotatable spray tube upon its bearings, any such occurrence being precluded by the rigidity of the combined supporting and wall-spacing means described. This is aconsideration of the utmost importance in view of the fact that for household use a dish washer should be as light as possible so that it .can be easily lifted 4from lace. Another advantageous feasupp y water substantially uniformly to the f spray device at all points.
eferring now to the particular form of rotatable spray illustrated, this embodies important novel features in and of itself. The tube 16, which may be of any desired cross-sectional shape, constitutes `an elongated chamber, having the end Walls 27 and 28 through which extends the supply pipe 17, and provided with jet apertures or devices for the discharge of liquid outwardly upon dishes in the receptacle. In the broaderl aspects of the invention the particular form and arrangement of these jet apertures or devices are not material; but in certain other and narrower aspects they areof considerable practical importance. In the construction here shown, the rotatable tube 16 is rectangular and substantially square in cross-section. It is provided with several longitudinal series of jet apertures, there being four such series in this instance designated 29, 30,' 31, and 32, respectively. Although the practice of the invention does not exclude the employment of more complicated jet devices, such as projecting jet tubes or nozzles on the rotatable spray device, the simple jet apertures,'consisting merely of perforations or small holes extending through the walls of the spray tube are found to serve admirably in ractice and are'especially recommended. ince it is desirable to utilize the reaction jet effect to rotate the spray tube, a sufiicient number of the jets should discharge tangentially with respect to the rotation axis toachieve this result. In the present instance, all the jets discharge tangentially, but at Vdifferent angles in order to more thoroughly cover the field to be sprayed. Thus. jet series 29 and 30 extend through the corresponding Walls of the tube perpendicularly or at right angles thereto; while series 3l and 32 extend obliquely through the .othei-,walls and hence streams of liquid ldischarged therethrough exert somewhat less propelling effect on the tube but, on' the other hand. diversify and enhance the cleansing action of the spray device as a whole, especially as the Obliquity of these two series of jets is opposite in order to\give a zig-zag, or oscillating spra` eiect as the tube rotates. Most desirably all the jets. are arranged to discharge at the maximum radial dist-ance from the axis of rotation permitted by the dimensions of the spray tube, thus securing the maximum reaction efect. i
In order to still further enhance thel thoroughness and effectiveness with (which the rotatable spray tube directs its cleansing streams to all points in the dish receptacle. it is desirable to mount the spray tube cc lll) Y 28a successively,
entrically. on the supporting pipe 17; or,
in other words, so that its longitudinal axis 1 s at an angle to the axis of rotation, said axis of rotation being the axis of pipe 17.
paths instead of the same path. Moreover,
the off-center mounting has the-further effect of varying the virtual radial distances of the jets in each series from the rotation axis, notwithstanding the fact that. the jets may be located, as'here shown, at substantially the same radial distance from the axis of the spray tube.
Referring again to the tubular fitting 19, this is formed interiorly with a chamber 33 into which fits a perforated soap container 34, the container having a screw cap closure 35, as shown. The-sides of the soap container are spaced away from the walls of the chamber to provide an annular passage 36 for free assage of water from the nipple 37 provi ed on said fitting 19 for a hot water hose connection 38. When the unitary anged fitting 19, includin the soap box and nipple, has been secure to the wall 13 of the container, it is a very simple matter to assemble therewith the other parts described. The tube 16 being held inside the receptacle with its end wall openings 27a and 28a in aliuement with the opemngin boss 21 and the opening 24 in the opposite wall of the receptacle, and clamping nut 26 being held between end wall 27 and adjacent Wall 13, the pipe 17 is passed through opening24, nut 26, and openings 27u and and screwed into the threaded channel in boss 21; after which cap 22's screwed onto the op osite end of pipe 17 until stopped by the ange 25, the milled head 22a rendering it easy to turn the cap with the fingers. The clampingnut 26 is thentu'rned down tight, a gasket (not shown) being optionally used on either the inner or outer side of the wall to ensure a tight joint. .It is equally easy to disassem-v ble the parts, which is sometimes 'desirable' in order to thoroughly clear the spray pipe of accumulated soap.A
Most desirably the rotatable spra.` is located Vcentrally within the vtacle or tank, and the dishes" and utensils-to be washedare supported proper-'position by means of racks or the likesubstantially surrounding said spray device. Thus on the floor or bottom ofthe receptacle are arranged racks 39 and 40 for such dishes as small plates and saucers; while at 41 are taller racks for larger plates, platters, and the like. A foraminous basket like holder 42 may be provided for spoons and cutlery'. Above the spray )device a foraminous tray or basket 43, which may be of wire, is removably supported as by lugs 44 resting upon a ledge 45, said lugs being secured to the rim or edge 46 of the tray. This tray is most desirably provided with lan open or `cut-out portion here shown as bounded by the cross-members 47, 48 and the rim 46.
This allows room for large dishes such as platters and large plates 49, standing on edge in racks 41 to project above the level of the tray bottom. Properly spaced pairs of members, as indicated at 50 and 51,- allow dishes such as tumblers and cups to be placed in the most ladvantageous positions on the tray bottom to receive streams of soapy water from the rotatable spray device.
The operation of the dish washer and its mode of use are suiciently evident from the foregoing description. With the dishes placed in the receptacle as shown, and a small. piece vof soap in the container 34,
connection to .a hot water tap is 'made by means of the hose or tubing 38 and the hot water turned on. The dish washer can conveniently be set on the drain board at one end of the u su'al kitchen sink, with the hose connec-tion 38 and drain outlet 14 toward the sink proper. Soapy hot Water flows into the supply pipe 17 and out through the apertures 18 into the spray tube 16 which -iS thereby kept full. Fine jets of water emerging from the several series of jet apertures immediately set the spray device in rapid rotation, and the cleansing jets are directed against the dishes in all parts. of the receptacle, the described construction and arrangement of the spray device making foi-'exceptionally thorough andrapid cleansing of the dishes;
-The effectiveness of the operation is fur- Vwater is admitted to the apparatus.. In actual practice it is found thatthe washer is very economical of hot water and that dishes treated thereby are vcompletely cleansed in a very few minutes.
