Abstract
Abstract A metal working machine having a two-high rolling mill in which two horizontally spaced frames support shafts for eccentrically mounting the roll housings. The roll housings are journalled in the frames. The shafts protrude through the frames and at a common end each shaft receives a lever which in turn is connected with articulation to a linkage system which can alter the distance between the roll housings and also respond to a piston drive to provide roll overload relief.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
189 words
In a metal working machine having a two-high roll stand including a mechanism for radially adjusting and for preventing an overload of the rolls, comprising: horizontally spaced roll stand frames; two vertically spaced shafts interposed between and linking said frames; eccentric journal means formed on each said shafts; a roll housing eccentrically mounted about each shaft; a radial roll adjustment linkage system having a lever secured at one common end to each of said shafts, each lever being constructed and arranged to establish a longitudinal axis whose location coincides with the main axis of the corresponding eccentric journal means, said axes defining a substantially right angle with an imaginary line defined by the axis of rotation of said shaft; linkage shaft means articulately connecting to each said lever for moving each lever to alter the radial distance between the roll housings; hydraulic piston drive means including a piston formed on said linkage shaft means and responsive to predetermined roll overload conditions to act upon part of said linkage system; and rotary drive means connecting to said lever and linkage system for controlling the rotary movement of said linkage system.
Claim 2
Dependent Claim
189 words
In a metal working machine having a two-high roll stand including a mechanism for radially adjusting and for preventing an overload of the rolls, comprising: horizontally spaced roll stand frames; two vertically spaced shafts interposed between and linking said frames; eccentric journal means formed on each said shafts; a roll housing eccentrically mounted about each shaft; a radial roll adjustment linkage system having a lever secured at one common end to each of said shafts, each lever being constructed and arranged to establish a longitudinal axis whose location coincides with the main axis of the corresponding eccentric journal means, said axes defining a substantially right angle with an imaginary line defined by the axis of rotation of said shaft; linkage shaft means articulately connecting to each said lever for moving each lever to alter the radial distance between the roll housings; hydraulic piston drive means including a piston formed on said linkage shaft means and responsive to predetermined roll overload conditions to act upon part of said linkage system; and rotary drive means connecting to said lever and linkage system for controlling the rotary movement of said linkage system.
Claim 3
Dependent Claim
35 words
In a metal working machine according to claim 1, wherein said linkage shaft means has a threaded extension at two opposite ends; a collar threadedly mounted about each threaded extension pivotably secured to each lever.
Claim 4
Dependent Claim
27 words
In a metal working machine according to claim 2, wherein one of said threaded extensions has a left hand thread and the other a right hand thread.
Claim 5
Dependent Claim
31 words
In a metal working machine according to claim 1, wherein said shaft means includes a radial enlargement; and stationary abutment in axial engagement with both axial faces of said radial enlargement.
Claim 6
Dependent Claim
28 words
In a metal working machine according to claim 1, and journal means on said housing and mounted in one said frames maintaining said housing in a vertical plane.
Claim 7
Dependent Claim
52 words
In a metal working machine according to claim 1, wherein the linkage shaft means of said linkage system comprises two axially relatively movable but rotatably rigidly connected shaft extensions; cylinder means receiving one said shaft extension for axial movement therein; the other said shaft extension being rigidly connected to said cylinder means.
Claim 8
Dependent Claim
29 words
In a metal working machine according to claim 6, wherein said other shaft extension is provided with a radial enlargement; and abutment means in engagement with said radial enlargement.
