WASHING-MACHINE nerreron.

Application filed May 19, 1922. Serial No. 562,209.

v drawings, forming part of this specification.

My invention relates to agitators for washing machines of the type which are moved to and fro in a tub containing a I quantity of clothing and washing water.

There have been a number of forms of agitators provided in the past in washing machines, the most familiar types being formed of wood. Thus there is a usual type made from a flat disk of wood having a series of pegs or arms extending from'it, which is widely used and known as a dolly.

The art is in bad need, however, of a light, noncorrosive metal agitator, which operates efiectively on the clothe in a washing machine tub without injuringv them or leaving any dead space where clothes are unafiected.

It is my object to provide such an agitator and in such agitator to provide for proper agitation to the clothes and proper setting up' of circulation of the water through the clothes without dead space. v

I accomplish my object by that certain construction and arrangement of parts to' be hereinafter more specifically pointed out and claimed.

In the drawings,

The figure is a perspective view of an agitator constructed according to my invention.

It will be noted that the exact form of agi tator shown is adapted to use in a machine the driving element of which oscillates the agitator to and fro. Thus the shaft 1 of the agitator shown is to be coupled to a driving means, while the agitator proper depends into a tub having washing water and clothes therein.

Formed in one piece with the hub 2, which is cast on the shaft, are arms 3, 3, extending in the same plane at opposite sides of the hub. These arms are comparatively narrow audits in a vertical plane adjacent the hub, but'at their ends are bent downwardly to face to currents of water.

form comparatively wide wings 4, 4, depending vertically and in line with the shaft 1.

' Also depending from the hub and lying The parts are formed without any sharp angles, the bottom of, the paddles particularly being formed as curves and the edges rounded and polished.

The blades or wings are pushed down into a tub of clothe and oscillated to thrust the clothes about in the tub, and the combined action of all three blades acting in differ-v ent planes, taken together with the largely foraminated structure of the paddles, gives just the correct action for thoroughly wash lug fabrics.

A piece of fabric carried along by a wing will be able to have the washing water flow through it and the water affected by the wings will not be so excessively thrown out, while being rapidly agitated at the same time.

In a preferred form my agitator is used in a tub so that the lower ends of the wings are below the center of the tub, and theradius of the arms from the central hub and shaft is about one half the radius of the tub.

Theaction of the central wing, being at right angle to the outer wings, is such that the clothes are given an added swirl, which would not be imparted if all paddles were in a straight line. The great importance of this wing 5 is the provision against dead or unagitated span at the center of the tub. The exact right angle is not requisite.

Modifications in form and proportion may be made in m structure without departing from the spirit thereof.

Having thu described my invention, what I claim as new and desire to secure by Let,- ters Patent, is

1. In a washing machine agitator, a mounting member adapted to move the agitator comparatively narrow plate, arms extending radially, said arms being provided with tvveen the outer blades, for the purpose described.

2. In a washing machine agitator, a mounting member adapted to move the agitator comparatively narrow plate, arms extending radially, said arms being provided With comparatively Wide depending plate blades at their outer ends with, the bottom edges rounded, and a central blade depending between the outer blades, said central blade being turned at an angle to the outer blades, for the purpose described.

3. In a washing machine agitator, the combination with a pair of interspaced comparatively Wide plate blades lying in the same vertical plane, of comparatively narrow aeaoee plate arms connecting said blades together,

the outer blades with the edges of said blades rounded.

4. In a Washing machine agitator, 'a mounting member adapted to move the agitator comparatively narrow plate, arms extending radially, said arms bein provided with comparatively Wide depen ing plate blades at their outer ends, and a central blade depending between the outer blades, said blades being fully foraminated and rounded at the edges, for the purpose described.
