Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
107 words
A waste incinerator, comprising a combustion chamber having a floor, at least one generally horizontal metal distributor bar adjacent to the floor, at least one support member spaced above the floor, non-rigid suspension means suspending at least one said distributor bar from an associated said support member, reversible driving means for moving the support member or members above the said floor to cause the distributor bar or bars to sweep at least part of the floor area, and a loading aperture for solid waste, at least one said non-rigidly suspended bar having a toothed edge and, opposite the toothed edge, a further edge forming a continuous blade.
Claim 2
Dependent Claim
107 words
A waste incinerator, comprising a combustion chamber having a floor, at least one generally horizontal metal distributor bar adjacent to the floor, at least one support member spaced above the floor, non-rigid suspension means suspending at least one said distributor bar from an associated said support member, reversible driving means for moving the support member or members above the said floor to cause the distributor bar or bars to sweep at least part of the floor area, and a loading aperture for solid waste, at least one said non-rigidly suspended bar having a toothed edge and, opposite the toothed edge, a further edge forming a continuous blade.
Claim 3
Dependent Claim
