Patent ID: 8490912

Claim:
A separator adjustment apparatus to adjust spacing between rotary separating members, said apparatur comprising: a tube having a first end, a second end and a perimeter wall extending between said first and second ends, said perimeter wall having a pair of elongated breaks therein extending through said first and second ends to partition said tube into a first section and a second section, said perimeter wall having an inner surface, said inner surface having a plurality of protuberances attached thereto, each of said protuberances having an angled edge being angled outwardly from said inner surface as said angled edges extend away from said first end and toward said second end; a coupler retaining said first and second sections together in a tubular configuration, said coupler including; a pair of plates, each of said first and second ends having one of said plates attached thereto to retain said first and second sections together in the tubular configuration approximating a cylinder; a plurality of bolts attaching each of said plates to an associated one of said first and second ends, each of said bolts extending through expansion slots in said plates to allow said sections to move toward or away from each other while being retained on said plates; an actuation assembly being mechanically coupled to said first and second sections to selectively move said first and second sections toward or away from each other, said actuation assembly including; a rod being mounted in said tube, said rod having an outer surface, said outer surface having a plurality of detents thereon, each of said detents having a facing edge facing one of said angled edges, each of said facing edges being angled outwardly from said outer surface as said facing edges extend away from said second end toward said first end, said detents urging said sections apart from each other as said rod is moved toward said second end; a shaft extending through and being attached to said rod, said shaft being threadably coupled to a knob abutting said plate attached to said second end, said knob being rotated with respect to said tubular member in a first direction to move said rod toward said second end and said knob being rotated in a second direction to move said rod toward said first end to alter a spacing distance between said first and second sections; and a plurality of separator discs being mounted on said tube so that said tube extends through said discs, said discs being movable on said tube when said first and second sections abut each other and are retained in place by friction between said discs and said tube when said first and second sections are moved apart from each other.
