Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
140 words
For use in a refiner installation, a refiner base, said base having a rectangular form and including a pair of longitudinally extended transversely spaced side walls consisting of generally uniformly flat plates the upper and lower extremities of which are bent inwardly to form integral upper and lower supports, said plates, through the medium of their upper bent portions, providing means to support thereon a refiner housing and transversely aligned means for supporting thereon a motor housing to either end of said refiner housing, further support means disposed transverse to said side plates to provide at the upper edge thereof supports for drive shafts of motors to either end of the refiner housing and means defining end panels forming interconnecting end walls for said side walls, said end panels providing thereon means for further bearing support of the motor shafts.
Claim 2
Dependent Claim
140 words
For use in a refiner installation, a refiner base, said base having a rectangular form and including a pair of longitudinally extended transversely spaced side walls consisting of generally uniformly flat plates the upper and lower extremities of which are bent inwardly to form integral upper and lower supports, said plates, through the medium of their upper bent portions, providing means to support thereon a refiner housing and transversely aligned means for supporting thereon a motor housing to either end of said refiner housing, further support means disposed transverse to said side plates to provide at the upper edge thereof supports for drive shafts of motors to either end of the refiner housing and means defining end panels forming interconnecting end walls for said side walls, said end panels providing thereon means for further bearing support of the motor shafts.
Claim 3
Dependent Claim
21 words
A refiner base as in claim 1 characterized by said end walls having a vertical depth less than said side walls.
Claim 4
Dependent Claim
37 words
A refiner base as in claim 2 characterized by means below said end panels providing for air to pass freely to and from the lower portions of said base interior, in a sense longitudinally of said base.
Claim 5
Dependent Claim
28 words
A refiner base as set forth in claim 1 characterized by said upper bent support portions of said side plates being relatively thicker than the lower bent portions.
Claim 6
Dependent Claim
53 words
A refiner base as in claim 1 wherein said lower bent supports on said side plates have in underlying relation thereto longitudinally spaced pad elements for elevating said base from an underlying support structure, said pad elements being in underlying relation to means providing for support of the drive shafts of said motors.
Claim 7
Dependent Claim
36 words
A refiner base as in claim 1 characterized by said end panels being imperforate and there being screen means mounted therebelow through which an air flow may pass inwardly of the ends of said base structure.
Claim 8
Dependent Claim
34 words
A refiner base as in claim 1 characterized by said upper bent portions of said side plates providing supports generally coextensive with said side plates and being reinforced in the plane of greatest stress.
Claim 9
Dependent Claim
44 words
A refiner base as set forth in claim 1 characterized by apertured cap means mounting ovEr respective end portions of said base and providing localized openings affording means defining a controlled path for circulation of air over equipment mounted in and to said base.
Claim 10
Dependent Claim
44 words
A refiner base as in claim 1 characterized by said further support means having formed therebetween a refiner well and including a truncated A frame at the top of which are bearing pads, through the medium of which said drive shafts may be supported.
Claim 11
Dependent Claim
79 words
A refiner base according to claim 1 wherein said end panels are structured to provide for air to pass freely to and from the lower portions of the base interior, in a sense longitudinally of the base, characterized by apertured cap means mounting over respective end portions of said base and providing localized openings affording means in cooperation with said end panels to define a controlled path for circulation of air over equipment mounted in and to said base.
