Abstract

Abstract A filter assembly (10) for use in laundry tubs or similar fluid receptacles includes a tubular body portion (11) having a plurality of holes (12) arranged in a plurality of bands (14, 16, 18). All of the holes (12) within one of the bands (14, 16, 18) have diameters of equal dimension. The diameters of the holes (12) increase from a relatively smaller dimension in the bands (14) at the ends of the body portion (11) to a relatively larger dimension in the band (18) at the middle of the body portion (11). The body portion (11) is secured to a waste drain (26, 26') by an elastic band (32) having a hook (36) at one end thereof and a rod (34) at the other end. The rod (34) is inserted in grooves (38, 38') in the end of the tube and, the elastic band is stretched through the body portion (11) and the hook is connected to a bar (37) in the drain (26, 26') to secure the body portion (11) to the drain (26, 26').
