Filtering and collecting device for water drains

A filter device for an outdoor water drain in a paved roadway gutter or the like, said drain having an outer protective grating 12 for preventing vehicles, pedestrians and large objects from falling therethrough, said filter device serving to separate and collect particulate impurities such as sand, twigs and leaves, and also oil and other liquid impurities passing through the grating, and comprising:

• a continuous holder member (1) adapted to be mounted beneath the drain grating, said holder member having downwardly depending, fluid impervious sides, a relatively rigid and shallow coarse-filtering wire basket (2) removably disposed within said holder member and having downwardly depending sides, and a fine-filtering bag (3) made of a flexible and water-permeable cloth or fabric material removably disposed around the outside of said holder member and depending downwardly beyond the sides thereof and substantially below said wire basket, whereby said bag may be shifted laterally away from a vertical axis of the filter device below the holder member to accommodate for irregularities in the drain structure, said holder member including support means (5) extending inwardly from lower edges of its sides for supporting the wire basket, and said support means also serving as a handle by which the holder member and bag may be lifted together to facilitate emptying the bag.
