FABRIC FILTER SHAKER ASSEMBLY

In a mechanical shake type fabric filter having a reciprocable shaker rack (10), a plurality of filter bag support caps (14) suspended from the shaker rack (10) and a fabric filter bag (11) suspended from each cap (14), the improvement that each cap (14) has a staple (16) formed on its upper surface which is releasably engaged with a hook (19) formed on the lower end of a support bar (17) which extends vertically through an aperture (18) in the shaker rack. The bar (17) may be retained in any vertical position relative to the shaker rack (10) by a spring clip (22) which is slidably positioned on the bar (17) but is deformed so as to frictionally engage the bar (17) when it contacts the shaker rack (10). The arrangement allows rapid adjustment of bag tension and simplified bag replacement.
