WASHING-MACHINE.

Application filed April 21,

To (1?? whom it may concern Be it known that I. J 011x M. BAKER. a citizen of the United States. residing at Columbus. in the county of Franklin and State of Ohio. have invented certain new and useful Improvements in lVashing-Machines, of which the following is a specification.

This invention relates broadly to washing machines or boilers and has for its primary object to provide amachine wherein an improved circulation of the cleansing fluid is automatically maintained, whereby clothes or other material contained within the machine will be subjected to the penetrating and cleansing influence of said fluid, in order to remove all traces of dirt or other extraneous matter therefrom.

Another objectof the invention resides in the provision of a washing machine wherein is provided a casing having a plurality of conduits positioned upon the interior side walls thereof. which conduits being provided with substantially open upper and lower end portions and a supplemental bottom member being situated within said casing on a plane substantially above the open lower ends of said conduits. said member serving to direct the circulation of the cleansing fluid to said conduits, whence the fluid may be circulated through the conduits and discharged into the interior of the casing by way of the substantially upper end portions thereof.

A further object of the invention resides in a washing machine which is adapted to operate in conjunction with a source of heat, whereby a circulation of water will be set up within said machine by the rise and fall in temperature of different portions of the fluid body.

A still further object of the invention resides in the peculiar construction of the conduits from wherein each of the latter are formed to embody relatively widened inlet portions and substantially restricted outlet portions. said outlet portions being shaped to defin nozzles which operate to spray the fluid discharged therefrom with considerable pressure upon the clothes deposited within the machine.

'ith these and other objects in view. as will appear as the description proceeds. the invention accordingly consists in the novel features of construction. combination of elements and arrangement of parts. hereinafter to be more fully described and having the Specification of Letters Patent.

scope thereof pointed out in the appended claim.

In the accompanying drawings, forming a; part of the-specification and in which similar characters of reference denote like and corresponding parts:

Figure l is a vertical sectional view taken through the washing machine comprising the present invention,

Fig. 2 is a horizontal sectional view taken along the line 2-2 of Fig. 1,

Fig. 3 is a fragmentary perspective view of the interior of the machines casing, and illustrating. more particularly the construction of the conduit elements,

Fig. 4 is a plan view of the supplemental bottoin member, and

Fig. 5 is a detail view of the actuating arm for the agitator structure.

Referring more particularly to the details of the invention, use is made of a washing machine or boiler A wherein is provided a. circular casing 1, said casing in this instance including a substantially flat bot-tom 2 and an annular and vertical side wall 3. A removable cover or top 4 is arranged to seat upon the upper peripheral edges of the wall 3 so as to interiorly inclose said casing and provides means whereby the insertion or removal of clothes or other ma terial to be washed may be readily effected with respect, to the casing. The top 4 in this instance is provided with a centrally and vertically journaled shaft 5 which projects into said casing and is provided with an oscillatory agitator or dolly structure 6, the latter preferably consisting of a plurality of downwardly and outwardly curved arms 7, which are adapted to engage in the usual manner with clothes deposited within said casing so that the same may have their relative positions altered to render the action of the cleansing fluid more positive. The structure 6 is preferably oscillated through the medium of an actuatingarm 8. which has one of its ends provided'with a bearing 9. the latter being adapted to receive a fixed stud 10. arising from a bracket 11 rigidly carried upon the upper surface of the top 4. This arm 8 is further formed with a depending and integral segmental rack portion 12, which is arranged to mesh with a pinion 13 carried upon the upper end of the shaft 5. By use of this construction it will be seen that by rocking the arm 8 about its pivot 10 oscillatory motion Will e impart d to the agitator structure as a whole and its operation thereby efl'ected. Through the use of other features of the invention,-to be hereinafter described it is not essential that the structure 6 should be contiguously operated, as the arrangement of the parts is such that an occasional operation on {part of said structure will be suflicient in enabling the washing machine to efficiently carry out its functions.

The casing 1 is adapted to contain a suitable quantity of a cleansing fluid and in operation the machine A is placed over a source of heat such for instance as a .gas burner or any form of stove, whereby through the use of which the'water or cleansing solution will be caused to attain a required temperature. In order to promote the circulation of the cleansing fluid so that the same will penetrate through all parts of the fabric contained within the casing and to thereby effectively loosen dirt or other matter therefrom, the invention contemplates the provision of a plurality of spaced conduit ele-v ments 14 which, in this instance, are mounted on the inside of the wall 3 of the casthermal rise and fall of said cleansing solution. The lower edges of the walls 15 and 16 are provided with outwardly turned flanges 20, upon which there is placed a supplemental bottom member 21, which is adapted to receive the material contained within said casing. This bottom member is provided with a depending annular ring 22 upon its under face, said ring directly contacting with the bottom 2, thereby serving to support the central portion of said member 21 and to space the main body of the latter from the bottom 2, the outer edges of said member 21 being received by the flanges 20 and in this manner firmly supported. Perforations'23 are formed centrally of said bottom member to permit of the passage, of the cleansing fluid therethrough. It will thus be observed that through the provision of said supplemental bottom member a heating chamber 24 is provided. between the bottom 2 and said member 21, which chamber being in open communication with the passages 19.

In operation, the cleansing fluid located 7 within the-casin -1 will flow into said chamher 24 by ivay o theperforations 23 and the perforatiogs 25 formed in the 22. In

this manner the fluid within said heating chamber 24 will receive directly the heat arising from the source of heat positioned beneath the casing 1, thus raising the temperature to the boiling point of the water within said chamber 24, or to a temperature higher than that of the body of water located above said member 21. Hence, owing to natural thermal laws, the water contained within said heating chamber will rise within the passages 19 of the conduit elements 14, whence the samej will be discharged in jet formationfrom said elements 14 through the medium of angularly disposed outlet openings 26 formed iin the latter. It will be observed that the upper portions of the conduits are somewhat restricted by reason of the inclination of the walls 15. This construction provides what is in effect a plurality of nozzles, so that the pressure or force of the water passingv through said jets or openings 26 will be relatively great so that the water thus discharged may exercise its maximum cleans- .ing influence. As the water cools the same will naturally flow into the chamber 24, whence it is again heated and the circulation in this manner thus maintained uniform and constant.

From the foregoing description taken in connection with the accompanying drawings, it will be seen that there is provided a machine of considerable utility and efiiciency,and one wherein its elements are so arranged as to cause its cleansing solution to be positively forced through the material or clothing contained within the casing so that all dirt or other matter may be positively freed therefrom. The bottom member 21 is preferably corrugated so that the same may exert an abrasive action upon the clothes, likewise, the walls 15 of the conduits may be similarly corrugated to present abrasive surfaces. Said bottom member is also formed in a dished manner to promote the flow of the cleansing solution toward the perforations 23. A handle 27 is also carried by said supplemental bottom member to facilitate the removal of the latter from its active position within said machine. The machine described is practically automatic in-operation and requires but a minimum of attention and labor, as intermittent operations of the agitator structure 6 will be sufii: cient to mix the clothing so that the cleansing solution may gain access to all parts thereof. By providing the walls 15 with the oppositely inclined portions 28, the jet openings 26 will be located on an angle with respect to the bottom 2, and in this manner the fluid discharged through said openings will be directly concentrated upon said clothing.

What I claim is:.

A washing machine comprising a casing,

including a bottom and a perpendicular Side wall, a plurality of conduit elements mounted stationarily on the inner faceof said side wall, said elements being formed to provide open lower ends which are spaced from said bottom and restricted nozzle forming upper ends, the latter terminating in inclined walls having angularly' formed ports provided therein capable of'directing a stream down,- wardly into the casing, flanges projecting from the lower portions of said elements, a perforated supplemental bottom member mounted within said casing and seated upon said flanges in spaced relation from said bottom, fine a heating chamber which is in direct communication with the open lower ends of said conduit elements, and a perforated ring support for said bottom member lying within said heating chamber and serving to sup port the central portions of said supplemental bottom member and to entrap foreign matter.
