ROTARY CLEALN'SER.

To all whom t may concern.'

Be it known that I, WILLIAM L. DEMING, a citizen of the United States, residing at Salem, in the county of Columbiana and State of Ohio, have invented a certain new and useful Improvement in Rotary Cleansers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to a machine for 'washing such articlesv as dishes, cooking utensils, knives,A forks, etc.

The general object of the invention is to provide ,such a machine which may be cheaply manufactured, simple in construction and very convenient to operate.

In carrying out my invention -I provide a rotary receptacle for the articlesl to be cleansed, mounted within a stationary casing and having means whereby a stream of water may rotate the receptacle, and I alsoprovide means for spraying cleansing liquidonto the articles to be cleaned whileithey are revolved in the receptacle. A. more specie object. of the invention is to so arrange the device that the dishes and other articles may be very conveniently placed in p0- sition in the receptacle so that it may be balanced and rotate evenly. A further object is to provide means controlling the cleansing water or other liquid and the water for rotating the receptacle, which, by operating a single member through a series of steps, may first wash the dishes with water and soap or other cleansing liquid, then rinse the same, while rotating the container, causing the air to dry the dishes after which the further movement of such member acts to discontinue the rotation.

My invention is hereinafter more fully described in connection with the drawings, and other-objects will become apparent in such description. The essential characteristics are summarized in the claims.

, of the controlling valve; Fig. 6 is a vertical central section through the valve casing and passages leading thereto; Figs. 7, 8 and 9 are sections through the valve casing showing successive positions of the plug in Specification of Letters Patent.

the operation of the cleanser. These sections are taken substantially on the line 7-7 of Fig. 5; Fig. 10 is a similar section through the lower portion of the valve ydevice, taken substantially on the line 1010 of Fig. 5; and Fig. 1l is a plan of the controlling device.

Referring to the drawings by numerals, .l indicates a substantially cylindrical casing shown as having a closed bottom 2, preferably slanting toward a draining opening,

shown as Vfitted with Va suitable screen v3 \be low which is a suitable waste passage 4. The casing 1 is shown as mounted on legs 5 which may be of any suitable construction. This casing' is preferably made of light sheet metal, andv has vits upper edge curved. in-l j wardly over areinforcing ring, as indicated at 7. Fitted; over. the upper'edge of the cas-A ing 1 is preferably provided an upwardly curved. or dome-shaped cover 10 having a embracing the upper edge of the casing.

Extending transversely `across the casing I have shown a bridge member 12 having its ends curved around the bead portion 7 and secured to the sides of the casing 1 at 14 by rivets or any suitable means. This bridge member carries a hollow ball bearing member l5 in which I provided an annular series of balls 16 adapted to engage the lsides of a vertical shaft. 17 and the under side of an annular flange or shoulder 18 rigid with the shaft. This shaft preferably eX- tends upwardly through the bridge member and may be provided with any suitable knob or rotating means, for lexample I have shown a crank 20. The lower end of this shaft is Iguided by an upwardly extending projection 22 rigidly secured to the bottom 2 and fitting a corresponding bore in the lower end of the shaft 17. This'shaft carries the receptacle for the articles to be cleansed, and it will be noted that the weight -is entirely supported on the balls 1G. the lower end of the shaft merely being positioned by the projection. 'f

The receptacle for the dishes preferably comprises a substantially horizontal plate member 25 secured and supported by' a spider 26'surrounding the lower end of the shaft 17fand rigid therewith. This plate 25, which is preferably of sheet metal, extends outwardly to a pointadjacent but separate from the cylindrical walls 1 of the casing,

"downwardly extending flange portion 11 and rising from its periphery isy a substantially cylindrical wall of woven wire, indicated at 28 and strengthened vat its upper end by a ring 30. Thus the plate and the wire wall 28 form, in eii'ect, a basketv rotatably mounted on the shaft 17. The ring 30 1s preferably braced by a transverse rod 31 secured at its ends-to offset portions 32 in the ring 30 and bound to the shaft 17 at its intermediate point. Depending from the transverse rod 31 are radially arranged vertical walls of open wire mesh dividing the basket into two compartments and form- `ing walls against which articles to be cleansed may bey rested or leaned. Toprovide for loading the two compartments of the basket receptacle with dishes so that the weight on opposite sides of the shaft may be substantially equal,I provide two radially arranged vertical walls 34 made of open l wire weave and secured to a U-shaped wire having its opposite ends rotatably embracing the shaft 17, as indicated at 36. The loops aroundthe shafts of the two movable walls rest one upon the other, and the lower loops rest upon'suitable collars, indicated at 37.' These walls maybe swung about the shaft 17 and are secured in any desired position by hooks 38, shown as secured throughclips 39 at the'upper portion ofthe wall and adapted to extend over and embrace the ring 30. j N

In leaning thedishes against the wall 31,

it is desirable to provide projections eXtending- Iupwardly from the plate 25 against which the edges of the dishes may rest to prevent `their displacement. This I accomplish by turning upwardly tongues `41 inte-` gral with the metal of the plate, thus leaving openings 40 through which water may drain while the dishes are being washed and rinsed. In placing the dishes in position it is desirable to begin by leaning them against the wall 31 and then one against the other at one side of the receptacle and then placing others at the opposite sides o f the rece tacle until the weight is vsubstantially even y divided. Then to prevent displacement of the dishes, the walls 34 are swung toward the, dishes and secured in position by the hooks 38.

The rotation of the basket receptacle is accom lished by providing, on the lower side o the plate 25 a'djacent its periphery, downward blades so faced that they may receive water 1n their concave side, projected Extending inwardly from another portion of thel valve 50 is a tube v52, having on itsA inner end, Ia nozzle 53, standing substantially midway of the height of the wall 28 vand adapted to project a cone-shaped spray inwardly against articles carried by the receptacle. Rlsing from the tube 52, adjacent the nozzle 53 is a pipe 55 which is curved-` inwardly and lies along the under side of the bridge 12 at 56,.being secured by a suitable clip 57. The portion 56 of this tube is f provided with a series of openings 58 on its under side adapted to project'small streams downwardly to the articles in the receptacle. At 60 is indicated a container for liquid soap or the like from whicha tube 62 leads tothe controlling device 50 where such liquid may be mixed withthe water projectf ed from the nozzle 53 and tube 60, depending upon the position ofthe operating member 65 for the valve device 50.

rThis controlling device is adapted in preferred form to direct hot water and soap onto the articles in the receptacle lirst, while at the same time directing water to the projections underneath the receptacle whereby 1t is rotated, then shut off the soap directing hot water to the dishes while the receptacle rotates, and then close olf the hot water whileV rotating only, whereby the dishes may be dried by such rotation. The

form of this controlling device illustrated in the drawings,'will now be described.

Referring to Figs. 5 to 11, 70 indicates a `casing or body of the controlling valve 50, shown as 4provided with a lvertical. taperedv opening into which is rotatably fitted a plug 72 having an upward extension 73 rigidly carrying the handle 65; extension is a ring of suitable packing mate- Surrounding the.y

rial 75, inclosed in a cap member 76 threaded onto the upper'end of the casing. Leadingtransversely toward the plug 72 is a hot water passage 77 to which water is led through' a suitable pipe 78 threaded into the casing, as shown. Water flowing through the passage 77 enters a sector-shaped opening communicating with an axial passage 80, v

leading downwardly to an exit passage 82 through which water lmay yflow to the pipe 52 and nozzle 53. This pipe 78, I prefer to use for hot water.

In the side of the body 70, opposite the` pipe 78, is a small pipe 62 leading from the liquid soap receptacle 60 under the control of a cock 63. This pipe communicates with a short passage adapted to register with a" groove 83 formed in the surface of the plug -70 and extending downwardly to a short passage 84 communicating with the exit passage for the hot water. To cause the soap to be drawn downwardly through these passages, I provide a short curved tube 85 having a contracted end opening toward the direction in which the water is iowing and I leading downwardly to an opening in the lower end of the stem 7 0 which receives the threaded end of a pipe 91 leading to the pipe 46 which as heretofore stated, leads water to the nozzle for rotating the basket receptacle.

The operation of this valve controlling device is as follows: With the handle 65 in the position shown in Figs. 5 and 6, the plug presents surfaces closing the passages 77, 83 and 89, and on turning the valve in the direction of the arrow in Figs. 7 to 9 and 11, a short distance, for example, one-eighth of a turn, the. sector-shaped openingsl of the passages 80 and 90 are brought opposite the passages v7 7 and 89 respectively, thus allowing hot water to pass through the pipe 7,8 throiigh the plug and pipe 52 to the interior of the casin where 1t is Jforcibly thrown against the dishes. This first movement also brings the groove 83' into position to allow soar to pass downwardlyfrom the tube 62 to t e short tube 85 and mix with the water vthrown against the articles-to be cleaned.

With the valve in this samey position the sector-shaped opening of the passage 90 registers with theo ening 89, thus allowin water (preferably cdid) to pass through t e pipe 88, passage'90' and pipe 91 to the nozzle45, wherel it is thrown against the'blades lllA on the under side of the receptacle, thereby acting to rotate this receptacle,whilethe hot water mixed with soap, or othery cleansing j fluid, is thrown against the articles' to be cleaned and these articles are revolved withf in the easing presenting all surfaces to the streams of water thrown onto the same. The

cleaning water passes outwardly through the open sides of the basket and downwardly through the openings 41 and is drained off Vthrough the draining opening in the bottom of the casing.

The above operation is continued long enough to thoroughly cleanse thedishes andl they maybe rinsed by turning the handle 65 another step in the same direction, thus 'bringing the groove 83 out 'of registration with the' passages for the soap thereby -closing the same while the sector-shaped openingsfor the hot and cold water still remain in registration with-the corresponding pas? sages, thus hot water is thrown upon the dishes which still continue to revolve. The position of the lug under the two conditions described, is shown in the sections in Figs. 7 and 8. It will be noted that in the firstl (Fig.` 7) the groove 83 is in registration with the soa passages and in Fig. 8 it is lbrought out o registration while the hot water passage. still remains in communication.

A' still lfurther movement of the handle brings the sector-shaped opening for the hot water passage out of registration with the passage 77 and also the passage 82 thereby stopping the flow of -hot water (this position is indicated vin F ig.v 9) but the opening for the cold water, extending through more degrees of the surface of the plug, may still remainin registration with the passage 89, thus the lcold water may continue to revolve the receptacle drying the dishes by the tendencyl of centrifugal force to throw the ing performed when a valveis in a certain position,`for example, in Fig. 11, the indicator stands over a mark labeled dry, meaning that the cold water only is passing through the valve which is acting to rotate the'receptacle causing the dishes to be dried,

as. above described.v

To prevent the operations'taking place in reverse order or out of ord r by inadvertently turning the handle in t' ewrong direc-- tionI may provide notches 97 inthe shank 73 of the plug and which may be engaged by a pawl 98 pivoted to the top of the oa'p and actuated by a spring 99. These notches are preferably so yarranged that each notch .may correspond to an operation so that it is, not necessary rto observe closely the posit-ion of the indicator, but to perform the complete operation, one need only move the handle so that each notch i's successively engaged by the pawl. The click of the pawl `indicates the handle has been brought to proper position for the next operation. In

' ,the particular form of valve shown, the

movement of the handle required for the several operations is materially less than the entire revolution, but the pawl prevents the handle passing in the wrong direction and the surfaces are so arranged that the valve remains closed from the time it is first shut oi' until it is brought around to the first operating position.

Economy of cold water may be effected by rotating the receptacle manually by means V'of the crank 2O and ,this handle is also useful .in connection with the motor. The starting of the rotation'may be hastened by the use of the crank. This may'sometimes be necessary when the receptacle is heavily loaded. In the top of the cover is indicated an opening 100 of a size adapted to pass freely over the crank irrespective of its position. This opening may permit the circulation of air over the dishes during the drying operation. Air entering through this opening may pass outwardly through a tangentially arranged passage 102 shown as closed by a pivoted cover 103 extending across the open end of this passage. It will be seen that as the dishes Within the receptacle are being rotated after the hot water is shut oft air will be caused to circulate rapidly and will enter through the opening 100 and be forced Voutwardly something after the manner of a blower through the opening 102 when the cover 103 is raised, as indicated in Fig. 1. Thus a very free circulation of the air is permitted over the dishes which, being heated by the hot water, tend to dry very quickly.

After the dishes are completely dried, as described by the above operation, 4the cover 10 may be removed, a suitable handle being provided at 105, thus allowing free access to the interior for removal of the articles'.
