Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
130 words
A support assembly for eliminator blades used to separate particles from a moving gas stream comprising: a base including a plurality of spaced bars extending transversely of a plurality of spaced vertical eliminator blades; said bars having a plurality of aligned grooves therein, spaced in accordance with the spacing of the blades, receiving a marginal base portion of a blade in respective grooves; at least one such transverse bar spaced above the base, the grooves of which receive a marginal side portion of a blade in respective grooves; and a movable detached bar having such grooves therein insertable transversely adjacent the top of said blades, the grooves of which receive a marginal portion of a blade in respective grooves; whereby the blades may be readily installed and removed for cleaning.
Claim 2
Dependent Claim
