Abstract
Abstract A disc refiner including opposed refining surfaces at least one of which rotates relative the other, characterized by said opposed surfaces being parallel and the center of one being radially offset from the center of the other. The disc refiner surfaces are each mounted on shafts, one of which shafts being adjustable to establish the surfaces in parallelism and to produce the desired radial offset thereof.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
132 words
A refiner comprising a pair of disc refiner units, at least one of which rotates relative the other, characterized by said disc refiner units having adjacent relatively opposed refining surfaces and in connection therewith means for applying said refining surfaces to produce an eccentric action on any pulp mass which is passed therebetween, each of said disc units having a fixed mount to a shaft, means mounting said shafts in an elevated relation to a base surface thereunder, and one of said shafts having a fixed orientation and the other having in connection therewith means for adjusting the orientation thereof to establish the opposed refining surfaces substantially in parallelism and to produce a selective offset of one of said refining surfaces relative the other whereby in operation to produce said eccentric action.
Claim 2
Dependent Claim
132 words
A refiner comprising a pair of disc refiner units, at least one of which rotates relative the other, characterized by said disc refiner units having adjacent relatively opposed refining surfaces and in connection therewith means for applying said refining surfaces to produce an eccentric action on any pulp mass which is passed therebetween, each of said disc units having a fixed mount to a shaft, means mounting said shafts in an elevated relation to a base surface thereunder, and one of said shafts having a fixed orientation and the other having in connection therewith means for adjusting the orientation thereof to establish the opposed refining surfaces substantially in parallelism and to produce a selective offset of one of said refining surfaces relative the other whereby in operation to produce said eccentric action.
Claim 3
Dependent Claim
35 words
A disc refiner unit as set forth in claim 1 characterized by the center of one of said disc units being radially offset from the center of the other between 0.005 inch and 1 inch.
Claim 4
Dependent Claim
35 words
A disc refiner unit as set forth in claim 1 characterized by the center of one of said disc units being radially offset from the center of the other between 0.020 inch and 0.080 inch.
Claim 5
Dependent Claim
92 words
A disc refiner, including a pair of discs having front faces in opposing adjacent relation, each disc being fixed to a shaft extending from its back face, at its center and perpendicularly thereof, means defining spaced bearing supports for each said shaft, and means included in the supports for at least one of said shafts for bodily shifting said shaft to accomplish precise parallelism of the said front faces of said discs and to achieve a selected nonaligned relation of said shafts for an eccentric offset disposition of said opposing front faces.
Claim 6
Dependent Claim
92 words
A disc refiner, including a pair of discs having front faces in opposing adjacent relation, each disc being fixed to a shaft extending from its back face, at its center and perpendicularly thereof, means defining spaced bearing supports for each said shaft, and means included in the supports for at least one of said shafts for bodily shifting said shaft to accomplish precise parallelism of the said front faces of said discs and to achieve a selected nonaligned relation of said shafts for an eccentric offset disposition of said opposing front faces.
Claim 7
Dependent Claim
64 words
A disc refiner according to claim 4, wherein there are means included in said supports for said one of said shafts which operate independently of one another whereby adjustment of one relatively to the other relatively tilts said discs and adjustment of both in conjunction with one another relatively offsets said shafts and said discs while maintaining parallelism of the front faces of discs.
Claim 8
Dependent Claim
59 words
A disc refiner according to claim 4, wherein said discs have a vertical disposition and said shafts extend horizontally therefrom, and said spaced bearing supports include pedestals spaced apart longitudinally of a respective shaft and a saddle mounted on each pedestal for relative raising and lowering movement, said saddles being each in an independent supporting relation to said shaft.
Claim 9
Dependent Claim
22 words
A disc refiner according to claim 6, wHerein each shaft is supported by a pair of longitudinally spaced-apart saddles on respective pedestals.
Claim 10
Dependent Claim
21 words
A disc refiner according to claim 6, characterized by means positively to raise each saddle and to control the lowering thereof.
Claim 11
Dependent Claim
72 words
A disc refiner according to claim 4, wherein said discs are surrounded by a case having an inlet for the entrance of material to be refined and an outlet for the discharge of refined material, and having further substantially oppositely disposed openings through which said shafts project, and a seal in at least one of said openings incorporating a flexible member to accommodate movements of a bodily shiftable shaft which projects therethrough.
Claim 12
Dependent Claim
70 words
A refiner according to claim 4, wherein said spaced bearing supports include a pair of spaced-apart pedestals for each shaft, characterized by a rotor fixed to each shaft, each rotor disposing between a pair of said pedestals, a stator surrounding each rotor, the rotor on a shiftable shaft bodily shifting in accompaniment therewith, and the surrounding stator being fixed relative the bearing supports for the shiftable shaft to move therewith.
