@riginal application led May 16, 1917, Serial No. 168,956. Divided and this application led June 15, 1917. Serial No. 174,856.

' To all 'whom z' may concern:

Be it known that l, THADnnUs W. HEER- MANS, a citizen of the United States, and a resident of Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Washing- Machines; and l do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which torni a. part of this specification.

This invention. relates to improvements in washing machines for washing dishes, silverware, glasses, and other like articles, and the invention consists in the combination and arrangement ot the parts shown in the drawings and described in the specication, and is pointed out in the appended claims.

The invention relates in part to a novel washing mechanism of the general character shown in my co-pending application for U. S. patent, Serial No. 98245, tiled May 18, 1916, wherein the container is divided into a lower well or compartment for limiting the quantity of the wash water used and an upper r for eleva s ne direction, cr downvmdly, ne washing compartment being separated from the well by a series of wall members which are constructed and arranged to provide indirect passageways from the washing compartment to the litting device, which are so formed as to provide settling, skimming and strainin means to remove the particles from the was water so that the water returning to the water elevating-means for re-use is clean.

The well is formed in' a reduced bottom oilthe container so as to limit the amount of xwash water handled and to correspondingly limit the amount of fuel use d to heat the water; it being, apparent that inasmuch as the water is cleaned between i ts= periods of use, a less volume or water may be used.

The figure ot the drawing 1s a partial front elevation and partial section ot a washing machine embodying my invention. As shown inthe drawings, 10 designates a container, preferably made of sheet metal.

It is provided with a removablecover 11, and the, bottom wall l2 thereof is formed with a depending reduced portion 13 which constitutes a well or compartment for the wash Water. 14 designates a stand pipe that is arranged centrally within the container.

The lower end of said pipe is formed with a downwardly open bell mouth 15, arranged centrally within the well. The upper end ofv the stand pipe extends to the top of the container and said upper open end of the stand pipe receives the lower end of a hollow bearing member 16, which is fixed to and depends from the removable cover and is formed to provide orifices 17 of an umbrella spray nozzle ina manner generally similar to the construction shown in my aforesaid application. As herein shown said bearing member 16 is provided with an upwardly extending threaded neck portion 18 that extends through the sheet metal cover 11 and is locked thereto by means of upper and lower nuts 19, 20, respectively, threaded t0 said neck portion 18. 2l designates a helical impeller that is rotatively mounted within the bell mouth 15 or" the stand pipe and which serves, when rotated at suitable speed, to lift the wash .water upwardly through the stand pipe for discharge through the orifices 17 or' the nozzle. rEhe impeller is mounted on the lower end of a vertical, rotative shaft :22 which extendsupwardly through the stand pipe and is rotatively mounted at its lower end in a bearing 23 carried by ribs 2e' which are made integral with the bell mouth ot the stand pipe. v. The shaft 22 extends its upper end into. a sleeve 26 that Ais rotatively mounted in an internal bearin of the member 16. Said shaft 22 is provided with squared or other polygonal portion 29 'which fits a like which, as herein shown, is grooved for engagement with a cylindric driving belt.

Surrounding' the bell mouth 15 of the stand pipe and rising from the bottom of the well is an annular or ring like shell 35 Whichis formed at'its upper edge to provide an inturned ledge 36. The internal diameter' of said ledge is sli htly greater than the external diameter o the base of the stand pipe, so that said stand pipe may be passed through the opening surrounded by the ledge, and thus removed from or inserted into place. Exterior to said annular .shell is an annular skirt 38 which is supported by webs39 integral therewith and with the shell 35. Said skirt terminates some distance above the bottom of the well and its lower 4edge constitutes a .skimming edge, for a purpose hereinafter described. The shell is surmounted by a dome shaped cover plate 40 -which fits closely over and upon the upper edge of the shell and is formed with a central upwardly extending neck 41 that surrounds the stand pipe, whereby said plate may be removed upwardly over the stand pipe. 'Lugs 42 serve to center the dome shaped plate on said shell'. Formed integral with the bell mouth of the stand pipe are a series of webs 45 which carry an integral ring 46 that rests on the ledge 36,v and .said ring and a shoulder 48 on the stand pipe constitute a support for an annular screen 50 that bridges the annular open space between'the stand pipe and the shell 35. The stand pipel is supported on the ledge 36 through the medium of the ring 46 and webs 45, and a ring 51 that is supported on the bottom of the well is connectedv to the shell 35 by integral radial webs 5 2 that serve as means to break up the.

body of water in the well when the impeller is rotated, and therefore prevent the body of water from being merely swirled by the impeller, with a result of losing the lifting elect thereof. 4

The dishes are contained vin a basket-like holder which is removably supported in the container,`it being adapted to be supported on the bottom wall 12 and on said dome shaped plate 40. It may be made of any suitable form and is of a size to lit closely within the container. A silver 'rack 56 is supported on the bottom of the holder around the stand pipe and is ada ted to be/ removed upwardly over the .stanI pipe.'

The operation of the machine is generally like that of ,the machine 4illustrated 'in my aforesaid application. Water is placed in the container to about the level indicated in the drawing. The water may be heated before it is placed inthe container or the water may be heated after being placedin the contalner and maintained hot by @suitable burner hereinafter described. `The im.

peller 21 is rotated rapidly throu h themedium of power applied to the pu ley 32V and acts to force the water upwardly through the stand pipe, from whence it is.

discharged through the oriices of the nozzle and falls down among and through the dishes or other articles in the holder. The water after passing the dishes finds its way to the well through the indirect passages formed between the skirt 38 and shell 35 v and through the screen 50. The solid, nonloating particles carried by the water settle by gravity to the lower partof the well exterior to the shell 35, while the solid, lighter particles, which float, are prevented from passing beneath the edge of the skirt 38, so that. thereby said particles may be said to bc skimmed from the water by said edge it may be kept at a suitably l1igh.tempera-'| ture, regardless of the chilling effect due to contact thereof with cold dishes and articles.

The machine is herein shown as supported like sof

on a swinging elevating frame of the same const ruction as shown in my pending application for U. S. Letters Patent, Serial No.

168,956, filed May 16, 1917, 'of Avylflichfthis application is a division. Inasmu'ch as the, supportin and elevating frame constitutes no part o the present invention the 'same is not herein specifically described. i
