The advantage of the new construction resides in the fact that the charging and discharging operations require con-- siderably less time and that the machine can therefore be longer in operation during onewo'rking hour, which isa matter of considerable importance in such relatively costly machines.

The idea underlying the invention can be similarly applied to washingmachines having for instance six or eight compartments, although this would entail some difliculties.

What I claim is: I 1. A washing machine having a horizontal,

The machine can then adjacent the opening in the adjoining compartment, said shell being provided with two horizontally opposed charging and discharging openings adapted to simultaneously register with a pair of compartment openings, and each opening being provided with a door.
