Universal frame for use with a fabric filter
Disclosed herein is a structure for a frame filter, which is adaptable for a wide variety of different housing. The frame filter in accordance with the instant invention includes a universal frame and a housing and fabric filter bag secured between the two members. The frame is rigid and in combination with the housing forms a clamping member to secure the filter bag between for rugged use including movement and shocking-type motion. The frame, in accordance with this invention, defines a picture frame having a central opening defined by an annulus. The frame includes clamping structure for attaching the fabric filter bag to the frame and the housing of an appliance. A wide variety of shapes are within the spirit and scope of the structure of the invention.
