Abstract
Abstract A rolling mill structure comprising a roll assembly insertable through a mill housing window. A roll housing carrying a roll is movable toward and away from another roll forming part of the roll assembly. A plunger is longitudinally movable along an inclined passageway intersecting the path of movement of the roll housing, and is inserted into a complementary recess in the housing to establish a predetermined roll gap. The plunger can be withdrawn from the housing and out of the path of the assembly without removal of the plunger from the mill housing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
191 words
A rolling mill structure comprising a mill stand, a mill housing forming part of said stand and having a window sized mill closely receiving a roll assembly; a roll assembly insertable through said mill housing window; said assembly including at least one slidably mounted roll housing having a roll rotatably mounted therein; said roll housing with said roll being movable toward and away from another roll forming part of said roll assembly to establish a variable roll gap between said rolls; and means mounted on said mill housing for so moving said roll housing, said means including a plunger longitudinally movable through a passageway in said mill housing and inclined to the path of movement of said roll housing, said passageway including a complementary inclined recess in said roll housing for engagement of said housing with said plunger, and means for moving said plunger along said passageway and recess into engagement with said roll housing to establish a predetermined roll gap and for withdrawing said plunger into said mill housing entirely out of said path to permit removal of said roll assembly without removal of said plunger from said mill housing.
Claim 2
Dependent Claim
191 words
A rolling mill structure comprising a mill stand, a mill housing forming part of said stand and having a window sized mill closely receiving a roll assembly; a roll assembly insertable through said mill housing window; said assembly including at least one slidably mounted roll housing having a roll rotatably mounted therein; said roll housing with said roll being movable toward and away from another roll forming part of said roll assembly to establish a variable roll gap between said rolls; and means mounted on said mill housing for so moving said roll housing, said means including a plunger longitudinally movable through a passageway in said mill housing and inclined to the path of movement of said roll housing, said passageway including a complementary inclined recess in said roll housing for engagement of said housing with said plunger, and means for moving said plunger along said passageway and recess into engagement with said roll housing to establish a predetermined roll gap and for withdrawing said plunger into said mill housing entirely out of said path to permit removal of said roll assembly without removal of said plunger from said mill housing.
Claim 3
Dependent Claim
55 words
The combination according to claim 1 wherein said plunger is disposed to move said roll housing toward said other roll, and said roll housing is provided with retraction means coupled thereto and to a stationary portion of said structure for moving said roll housing in a direction generally opposite to that induced by said plunger.
Claim 4
Dependent Claim
22 words
The combination according to claim 1 wherein stripper means for said another roll are rotatably and slidably mounted upon said roll housing.
Claim 5
Dependent Claim
81 words
The combination according to claim 1 wherein said mill stand is provided with elevatable internal rail means mounted generally below said roll assembly, said roll assembly is provided with wheel means for engaging said rail means, means are provided for elevating said internal rail means to engage said wheel means and to align said internal rail means with external rail means to permit withdrawal and insertion of said roll assembly relative to said mill housing window upon withdrawal of said plunger.
Claim 6
Dependent Claim
82 words
The combination according to claim 4 wherein said elevating means include a screwdown mechanism mounted in the lower end portion of said mill stand and engageable with said roll assembly for operational support thereof, said mechanism in addition being coupled to said rail means but extending therethrough so that upon engagement between said rail means and said mill housing at a lowered position of said rail means and further actuation of said screw mechanism said screw mechanism supportingly engages said roll assembly.
Claim 7
Dependent Claim
57 words
The combination according to claim 4 wherein traction means are mounted adjacent said internal rail means for withdrawing and inserting said roll assembly through said mill housing window, said traction means including a latch member movable by said traction means and disposable thereby for engagement with said roll assembly upon upward movement of said internal rail means.
Claim 8
Dependent Claim
181 words
A rolling mill structure comprising a mill stand, a mill housing forming part of said mill stand and having a window for closely receiving a roll assembly, a roll assembly insertable through said mill housing window, elevatable rail means movably mounted in a lower portion of said mill housing and generally beneath said roll assembly when so inserted, external rail means juxtaposed to said internal rail means, said roll assembly having wheel means for engaging said internal and said external rail means, and means for elevating said internal rail means for engagement with said roll assembly and for alignment with said external rail means, said elevating means including a screwdown mechanism mounted in the lower enD portion of said mill stand and engageable with said roll assembly for operational support of said assembly, said mechanism in addition being coupled to said rail means but extending therethrough so that upon engagement between said rail means and said mill housing and further actuation of said screw mechanism at a lowered position of said rail means said screw mechanism supportingly engages said roll assembly.
Claim 9
Dependent Claim
181 words
A rolling mill structure comprising a mill stand, a mill housing forming part of said mill stand and having a window for closely receiving a roll assembly, a roll assembly insertable through said mill housing window, elevatable rail means movably mounted in a lower portion of said mill housing and generally beneath said roll assembly when so inserted, external rail means juxtaposed to said internal rail means, said roll assembly having wheel means for engaging said internal and said external rail means, and means for elevating said internal rail means for engagement with said roll assembly and for alignment with said external rail means, said elevating means including a screwdown mechanism mounted in the lower enD portion of said mill stand and engageable with said roll assembly for operational support of said assembly, said mechanism in addition being coupled to said rail means but extending therethrough so that upon engagement between said rail means and said mill housing and further actuation of said screw mechanism at a lowered position of said rail means said screw mechanism supportingly engages said roll assembly.
Claim 10
Dependent Claim
74 words
The combination according to claim 7 wherein said mill housing is provided with stop surfaces for engaging said roll assembly when said internal rail means are lowered, and a plurality of clamp mechanisms are spacedly mounted on said mill housing, said clamp mechanisms including clamp members extending through passages therefor in said mill housing for engagement with said roll assembly to clamp said roll assembly within said mill housing and against said stop surfaces.
Claim 11
Dependent Claim
62 words
The combination according to claim 4 wherein spindle carrier means are mounted on said stand adjacent said mill housing window in alignment with journal means for said rolls for supporting at least one spindle coupling therefor prior to connection with said rolls, said spindle carrier means being at least partially mounted on said internal rail means for elevation and alignment movement therewith.
Claim 12
Dependent Claim
80 words
The combination according to claim 1 wherein said roll assembly includes a first pair of rolls and a second pair of rolls mounted substantially at right angles thereto, a housing for one of said first pair of rolls is so moved, and additional means are mounted on said mill housing for moving at least one of said second pair of rolls toward and away from the other second roll to adjust a roll gap between said second pair of rolls.
