-It will thus be seen that in the operation 'of the
device, the air is drawn from the tub through
theblower and discharged into the. bottoml of
the tub and passes upwardly through the water,
ì thus serving to agitate it.
Itv will be understood that by adding soap va
desired suds may be produced.
, ’
I have found that by using air for the agitator
instead ' _of employing- a mechanical agitator, I
am able to create and maintain a much better
supply of suds.
'I'he soap bubbles gather vat the top of the
35 water in the tub insuch quantityvthat they tend
to get out through the joint around the lid and
pile upy on top of the tub. 'I‘his is a decided objec
tion to washing machines and the like which em
ploy air for 'agitating water and washing the
40 clothes and forming a suds. lMuch complaint has
been experienced because of the fact that the
suds gather in a pile on-top of the tub.
I have provided means for creating slight vac

to cause slightiniiow of air into the tub around
the cover 2,2. 'I'his inñowing air vwill prevent' the escape of soap bubbles around the cover and pre 25
vent the collection 'of a pile of soap bubbles on
top of the tub.A
By this arrangement,v I am able to utilize the
advantages of air agitation of the water in a
washing machine or the like, and am able to 30
take advantage of the creation of a large- amount
of suds and at the same time to prevent the es-cape of the suds from the tub and the collection
thereof on the top of the tub and on the apron I3.
It will, of course, be understood that some 35
changes may be made in the construction and ar
rangement of the parts ofmy improved structure,
and it is my purpose to coverv by my claims any
modified forms of structure or use of mechanical
equivalents, which may be reasonably included
' within their scope.
