WILLIAM H. DUNN, OF CHICAGO, ILLINOIS, ASSIGNOR T0 DUNN MANUFACTURING 00., OF CHICAGO,

CLEANSING MACHINE.

Application filed July 19,

The invention relates to cleansing machines, and has among its various objects the provision of a construction where n the entire body of water or other cleansing material is thoroughly agitated and directed towards the articles to facilitate the cleansing of them.

The invention will herein'be explained in conjunction with a machine employing rotating fluid agitating elements which when 1n operation sets the fluid in action, and causes it to be directed towards the articles to be cleansed.

In machines of this or similar constructions it has been found that the fluid between the uppermost ends of these rotating elements and the uppermost end of the container rotates or whirls in unison with these elements and is not directed upon the articles and accomplishes no work. It is an object of this invention to provide a structure which will destroy this whirling motion of the fluid and direct it into a course from which beneficial results may be obtained.

The invention has these and other objects, all of which will be explained in detail and more readily understood when read in conjunction with the accompanying drawings, in which one embodiment of the invention is described, it being obvious that other arrangements may be resorted to without departing from the spirit of the invention as expressed in the appended claims.

In the drawings Fig. 1 is acentral section of a cleansing machine embodying one form of the invention;

Fir-j 2 is a sectional plan view of a portion i the structure shown in Fig. 1;

Fig. 3 is a detail view of a portion of the device shown in Figs. 1 and 2; and

Fig. 4 is a perspective view of the device shown in Fig. 3, showing its connection with another portion of the structure.

The invention will be explained as applied to a cleansing machine which includes a container for the fluid, a pair of rotating fluid agitating arms arranged in the container, and a receptacle into which the articles to be cleansed are placed, the latter of which is provided with means cooperating with said arms to direct the fluid towards the articles to be cleansed.

This fluid container is designated by the numeral 10 and is provided with the valve controlled drain opening 11, and carries a 1920. Serial No. 397,406.

motor 12 having a. pinion 13 which meshes with a beveled gear 14 rigidly secured to the shaft 15. This shaft projects inwardly beyond the lowermost wall of the container, and is journalled in a bushing'16 which is packed so thatthe fluid is prevented from leaking therethrough from the container. The uppermost end of this shaft has a squared end which is arranged in the squared downwardly facing opening 17 of the fluid agitating element generally designated 18. This latter element may be of any desired or suitable construction, that herein shown consists of a pair of

arms

19 and 20 which radiate from the hub, the latter of which receives the stub shaft. These arms extend along the bottom of and upwardly along the sides of the container and terminate below the top thereof, and rotate between the walls of the fluid container and the receptacle 22 into which the articles to be cleansed are placed.

This receptacle is of a spidered formation and consists of the arms 2323 which may arms are connected to a suitable collar 24 which rests upon a ln'oulder at the opening of the container and supports the receptacle formed by these arms when said receptacle is arranged in the container. This receptacle is provided with a wire netting or other suitable structure 25, and prevents a person from inserting his hand or fingers between the arms 23 and the rotating

arms

19 and 20. The uppermost ends of these arms are each provided with a web 26 which extends downwardly from the collar 24 to near the upper ends of the rotatable arms 19 and '20 and transversely across the space between the arms 23 and the wall of the fluid container, and are also. curved transversely to their length. These webs are arranged in that space provided between. the uppermost ends of the rotating arms and the collar 24, and are provided to destroy the useless whirling action of the fluid which takes place near the top of the fluid container between the collar 24 and the uppermost ends of the retating

arms

19 and 20, and to divert and compel it to ursue a course in which'it will perform wor To accomplish this advantage these webs are arranged to project into the path of the fluid as it 15 set in motion by the

arms

19 and 20, and are constructed so as to direct the fluid from the sides of the fluid container towards the center thereof. By virtue of the fact that these webs are arranged near the top of the container the fluid which comes in contact therewith will be thrown towards the center of the receptacle and upon the top of the articles arranged in the container, causing it to circulate towards and through the articles and to perform workduring its circulation.

Whereas these webs are herein illustrated as being part of the arms 2323, 1t 1s ev1- dent that they may be cast integral with the fluid container or otherwise made a part thereof.

A means is also provided for directing the course of the fluid as it leaves the webs and to prevent it from being thrown beyond the edges of the container. The means conslsts of a plurality of curved segmental downwardly projecting inclined flanges 27 whlch extend a suitable distance alon the inner periphery of the collar 24, an project a suitable distance from each web in a direction reverse to the movement of said rotating arms.

The action of the cleansing fluid which takes place in a machine employing the structure illustrated is substantlally as follows. The rotating

arms

19 and 20 and their cooperation with the arms 23 causes the fluid to be set in motion and directed from the bottom and sides of the container towards the center thereof. That fluid between the uppermost ends of the rotating arms and the collar 24 is caused by virtue of the rotation of the arms to move in a circular course with said arms. This fluid is therefore brought into contact with the radial webs 26 which intercept it in its rotation, and converts this motion from rotatable to lateral or inward toward the center of the container, causing it to be brought into contact with the articles to be cleansed instead of rotating around them.

Having thus described one embodiment of the invention it is obvious that others may be resorted to without departing from the spirit of the appended claims.

What I claim and desire to cover by Letters Patent is:

1. In a cleansing machine the combination of a fluid container, agitating means arranged in the container, a receptacle into which the articles to be cleansed are placed, said receptacle having means for directing the fluid towards the center of the container, said means having portions which extend into the path of the fluid arranged between the container and the receptacle.

2. In a cleansing machine the combination of a fluid container, rotatable agitating means arranged in the container, a receptacle into which the articles to be cleansed are placed, said receptacle having means cooperating with the rotatable agitating means for directing the fluid towards the center of the container, and deflecting means arranged to extend into the path of the fluid, said means being positioned near the top of the container and above the agitating means whereby the fluid above the agitating means is also directed towards the center of the container.
