Application May 15,1941, SerialrNo. 393,521,` ,v
¿This invention relates tofwringers of the type ,
used in connection with motor driven domestic `
washing machines, and particularly to that type
of wringer wherein a rinsing operation is per
formed. This application is an improvement on
the rinse wringer set forth in my co-pending
application, No. 368,159, filed December 2, 1940,
now Patent No. 2,358,256, granted September 12,
The particular object of the present invention
is to provide improved conveyor and rinsing
means in the rinse chamber of the wringer.
Other objects and benefits will be disclosed in
the following descriptions and drawing, in which
drivingrolls are designated 4IIL-l5 and lli-Il.l
The water level in the rinse 4ehangrber in each`v
case is designated by the letter L.
Now referring to Fig. 1, I show a wringer hav
ing a beltl I8 'extending over the lower rolls Il, |6,~
and driven thereby. The belt in all cases .isV
perforated by holes I8’» to permit rinse water to
be >drained readily through the belt. In some
cases I may desire to, have rubber fingers I9 on `„
theA belt, which lingers will‘be proportioned and
arranged to lift clothes as they come through
the rolls, thus agitating and holding them up
