Abstract
Abstract Paint filtering apparatus for supporting a filter medium, such as foraminous cloth or the like, above a paint pail. The apparatus includes an impervious plate larger than the mouth of the paint pail and legs for supporting the plate above a surface on which the paint pail can be rested. The plate defines a circular opening having a diameter smaller than the diameter of the mouth of the paint pail. A cylindric rim that is sized to fit within the hole in the plate and having protrusions fastened thereto for bearing on the plate to retain the rim in place. Above the protrusions the rim defines an annular groove, and there is a strap that can be placed in the groove to retain the filter medium within the groove throughout the extent thereof. The rim is smaller than the diameter of a paint bucket so that a paint bucket can be rested on the rim in an inverted position to afford draining of the same without continuing attention.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
175 words
Apparatus for filtering paint comprising: a pail having a given diameter and a given height, a rigid impervious plate having length and width dimensions exceeding the given diameter, means for supporting said plate in parallel relation above a surface by a distance in excess of the given height, a central portion of said plate defining a circular opening having a diameter less than the given diameter and positioned directly above said pail, a generally cylindric rim having an outer diameter sized for entry into said opening, means protruding radially outward of said rim for bearing on said plate to retain said rim within said opening, said rim defining an exteriorly open annular groove therearound above said bearing means, a strap sized for entry in said groove, and means for tensioning said strap to retain the strap in said groove so as to retain a filter medium therein throughout the periphery thereof, said rim being smaller than the diameter of a paint bucket whereby said bucket can be rested on said rim in an inverted position.
