WASHING MAGHINE Application filed February, 1930. Serial No. 430,988.

tear the clothes, and my object is to devisev a machine of this type which will eifectively move the clothes in the tub without undue wear and tear.

I attain my object by means of a construction which may be briefly described as follows. Within a tube is mounted an agitator comprising a disk located adjacent the bote tom of the tub and secured to a sleeve extending upwardly and driven by a drive shaft extending through the bottom of the tub. Up from the disk extend a plurality of cylindrical pins which reach toy a `point abovethe upper surface of a wash for which the tub is designed. These pins are preferably positioned about midway between the sleeve and the wall ofthe tub.

The invention is hereinafter more specically described and .is illustrated in the accompanying drawings in which -Fig. l is a vertical section of a washing machine showing only parts relating to rn invention; and l Fig. 2 a plan view of the same.

In the drawings like numerals of reference indicate corresponding parts in the different i'igures.

Referring to the drawings, l is a, tub formed of metal and shown as supported on the legsQ. Projecting upwardly from the bottom of the tub is a sleeve 3 which extends well above the normal water linev of the tub. Through this sleeve extends s by any suitable means (not shown). Y

Y' Within the tub is positioned an agitator which comprises the `disk 4a, the cylindrical sleeve 5 and the upwardly extending pins 6. The sleeve 5 embraces thesleeve k3 and its upper end is! squared to receive the squared upper end of the driving shaft t which Will be given an oscillatory'movement by any suitable mechanism. The disk 4a,

it will be noted, is considerably less in diameter than the wall of the tub 1 andrto it, adjacent its rim, are secured the pins 6 which are preferably cylindrical in form and parallel tothe axis of the agitator and have f their upper ends formed with hemispherical caps 7, of greater diameter than the pins, which prevent injury to the clothes when the latter are being-,introduced in to thev tub. These pins alsoy extend well above the normal water level of the tub when the latter contains a wash of the size for which the machine is adapted with` .af suflicientA margin for any probable higher level. When the clothes are introduced into the tub they lie between the sleeve 5 and the ywall l of the tub and between and not over the pins 6. The wall of the tub is`,` of course, vsmooth and free' fromv projections.v Further they positioning of the pins 6 isrsuch that they .carry the clothes back and forth without exerting any materialoutward pressure, thereon. rIh-e clothes are thus thoroughly agitated and swirled through the water without coming into contact with any projecting i pins or surfaces which will cause scuiliing or wear, theresult Vbeingthat the clothes are thoroughly cleansed in a shorter period of time than is possible .with ordinary con-l structions.V j j What I claim as myinventlon is:

. 1. In a washing machine the combination i of'a tub; an agitator mounted therein to revolve on a vertical axis comprislng'a disk locatedadjacent the bottom of the tub7 a `1 central sleeve extending `above thenormal. water level in the tub, and a Lplurality of upwardly extending pins carried by the disk yparallel tothe axis of the agitator and also the tub.

3. A Washing machine constructed as set forth in claim 1 in which the pins are lo-V cated approximately midway between the axis and circumference of the tub.
