  • Patent number: 9394642
    Abstract: A basket assembly (24) for a washing machine includes a basket and a support bracket (36) adjacent the basket. The basket has a first end (54) and a second end (56) and defines a cavity at the first end for receiving laundry. The support bracket (36) includes a base (40) having a front side (42) and at least two attachment portions (60) extending from the front side. The attachment portions are spaced from each other and are connected to the second end (56) of the basket. At least two fins (74) integrally extend from the front side of the base toward the first end of the basket. The fins (74) are integral with the attachment portions (60) of the support bracket (36) for reinforcing the attachment portions.
