Elongated retainer strips for fibrous filter batts
First Claim
1. An improved elongated retainer strip for securing a fibrous filter mat and a backing screen to the supporting frame of a filter cell, wherein said elongated gripping strip is of the type generally having a base wall, a pair of side walls extending upwardly from each edge of said base wall and a downwardly and inwardly extending resilient semi-wall depending from the free end of each of said side walls terminating in spaced free edges to define a slot in opposing relationship to said base wall, wherein said improvement comprises:
- a. a first flange integrally depending from one edge of said base wall and extending in parallel, spaced relation to the outer surface of said base wall and defining a first longitudinally extending trackway between said flange and said base wall for receiving and retaining one of said backing screen and said supporting frame; and
b. a second flange integrally depending from one edge of one of said side walls and extending in parallel, spaced relation to the outer surface of said one side wall and defining a second longitudinally extending trackway between said second flange and said one side wall for receiving and retaining the other of said supporting frame and said backing screen.

Abstract
An elongated, generally U-shaped in cross-section, retainer strip, of the type which includes longitudinally extending, resilient, confronting semi-walls extending inwardly and downwardly from the free ends of the legs to grip the edges of a fibrous filter mat, includes a pair of exterior flanges. One exterior flange extends in spaced, parallel relation to one of the walls of the retainer strip to mount the retainer strip on a planar portion of a filter frame without rivets or cement. The other exterior flange extends in spaced, parallel relation to another wall of the retainer strip to secure the edges of a conventional screen or mesh backing member eliminating sheet metal tabs.
