Application filed May 7,

This invention relates to washing machines, and'particularly to washing machines of that type wherein the clothes are placed'within an oscillatable container or cradle.

The general object of the present invention is to provide a washing machine of this character having what may betermed a false bottom formed of a corrugated screen, this false bottom supporting the clothes and the false bottom being disposed in spaced relation to the bottom of the cradle or container so as to provide a space through which the water may violently rush as the cradle is rocked, this rushing ofthe water beneath the clothes causing the water to run upwardat the rounded ends of the cradle and be dashed downward onto the clothes and also tending to cause the movement of the clothes upon the corrugations. y

A further object is to provide a device of this character in which the free flow of water will not be obstructedin any manner and which is particularly effective for this reason.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawing, wherein V Figure 1 is a vertical longitudinal section of a washing machine constructed in accordance with my invention;

Figure 2 is a vertical sectional view thereof Figure 3 is a fragmentary horizontal section through the bottom of the washing machine.

Referring to this drawing, 10 designates the clothes container orcradle, asit maybe termed, having rounded ends 11 and the bottom 12. At the lowest point of the bottom there is provided the drainage opening 13 normally closed by a plug or tappet. Attached to the sides of the cradle 10 are the rockers 14; and these operate upon the longitudinally extending angle iron rails 15. Each of these rails is supported at its extremities by the folding legs 16 held in normal position by the braces 17. Preferably each of the rails 15 is provided with an upwardly projecting pin 18 and each rocker has an opening through which the pin may project as the container is rocked so as to prevent any slippage of the container relative to the rails upon which it rocks. V

A latch 19 is illustrated as pivoted upon one of the rails and engaging a pin 20 so as to lock the container against oscillation when 1927. Serial No. 189,674.

desired. The top of the container isprovided with a lid 21 normally closing the opening through which the clothes are placed. Also mounted upon the top is an upstanding wall 22 designed to direct water from a wringerba-ck into the container 10. 23 designates-means for supporting the wringer.

The important feature of my invention resides in the fact that I provide a curved screen 2& which is preferablytransversely corrugated, as at 24, which extends approximately parallel to the bottom 11 and transversely across theentire width of the body 10 and is open at the ends so as to form a channel beneath the clothes wherebythe water washing up on one end of the body as the body is rocked will rush violently through the channel to the other side of the body and be dashed downward upon the clothes. This screen may be also provided with perforations 24 through which the water may pass and may be of any suitable material.

The screen is supported at its side margins upon the framing members or rails 25 which are provided at intervals with the upstanding heads 26. The screen'at its side margins is formed with keyhole slots 27 adapted to receive these headed nails or fasteners 26. Preferably the screen is supported by means of one or more intermediate longitudinally extending supporting rails 28 extending from one end to the other of the screen. The screen is spaced at its ends from the end walls of the body 10 to provide openings 24 at the ends of the screen. The screen, as before stated, is formed at its margins with keyhole slots 27 and held in place by the headed fasteners 26. This permits the screen to be detached. As illustrated, the screen is formed in two sections so that one or the other section may be readily removed when the screen is detached from the fasteners 26 and this permits the screen to be taken out and thoroughly cleaned and the bottom of the receptacle thoroughly cleaned.

As illustrated, the end wallsof the body are provided with the inwardly extending baffles 29 which act as the water is discharged from the openings, to cause the water to be dashed downward onto the clothes. I regard the spacing of the rubbing screen 24 from the bottom of the receptacle so as to provide a longitudinal channel as being a most important feature of my invention. After the water and clothes are placed in the receptacle 10 and the receptacle is rocked, the clothes, were it not for the open channel, would obstruct the free flow of the water. By providing the channel, however, the water is caused to flow Violently through this channel from one end of the space between the screen 24 and the bottom 12 to the other end 7 thereof and as it races through under the clothes it causes a downward suction on the clothes, which draws out the dirt. Furthermore, as the water rushes through and under the clothes and reaches the outer end of the curved end walls, it is thrown back on top of the clothes with a dashing and rushing force. r

I do not wish to be limited to the particular torino't support for this rocking receptacle nor the details of construction of the receptacle itself, nor do I wish to be limited to the exact l'orm ot the screen or rubbing board inasmuch as any screen which will support the clothes in spaced relation to the bottoinot the receptacle may be used. I do regard, however, as the important feature of my invention that. there should be this space between the clothes and the bottom of the receptacle so as to hold the clothes off the bottom of the receptacle and permit. the free flow of water from one end of the receptacle to. the other as the'device is rocked and the tree discharge of the water down Ward and inward onto the clothes in the receptacle from the openings at the ends of the screen, that is the openings left between the screen at the ends t-hcreot and the wall 01? the receptacle 11.

It will be understood that this washing machine may be rocked by any suitable means.

I claim: v

A washing machine of the character described including a supporting tran'ie, a receptacle mounted for rocking movement upon thetraine, the rece )tacle having upwardly extending rounded ends and having longitudinally extending; rails disposed in the bottom of said receptacle at each side thcreo't and formed with upwardly extend- I ing studs, and a perforated screen disposed within the receptacle and lCStlllf' upon said rails and being thus supporter in spaced relation to the bottom and ends of tie receptacle, the screen having uprmrdly rounded end portions, the screen being transversely corrugated and being formedwith apertures at. its margins through which said studs en
