Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
123 words
A method for cutting annular bodies from a stone block, said method comprising: providing in a rock material block a mounting hole and a saw hole spaced from the mounting hole, clamping the block to a rotatable surface by passing a clamping bolt through the mounting hole, providing an endless saw wire, leading the saw wire through the saw hole that passes through the rock material block, supporting the wire to define a working run that extends through the saw hole in the block, causing the wire to move along the working run, setting the block into rotation about a vertical axis while the saw wire is moving along its working run to effect in said block cuts about said axis of rotation.
Claim 2
Independent Claim
123 words
A method for cutting annular bodies from a stone block, said method comprising: providing in a rock material block a mounting hole and a saw hole spaced from the mounting hole, clamping the block to a rotatable surface by passing a clamping bolt through the mounting hole, providing an endless saw wire, leading the saw wire through the saw hole that passes through the rock material block, supporting the wire to define a working run that extends through the saw hole in the block, causing the wire to move along the working run, setting the block into rotation about a vertical axis while the saw wire is moving along its working run to effect in said block cuts about said axis of rotation.
Claim 3
Independent Claim
89 words
A method of making annular bodies from rock material blocks, said method comprising the steps of drilling a first hole through said block, drilling a second hole through said block, said second hole spaced from said first hole, securing the block on a rotary block-holding table by passing a tie rod through said first hole, said table rotatable about a vertical axis, threading a saw wire through said second hole, imparting a cutting motion to said saw wire, and moving said block rotatively about said vertical axis of rotation.
Claim 4
Independent Claim
89 words
A method of making annular bodies from rock material blocks, said method comprising the steps of drilling a first hole through said block, drilling a second hole through said block, said second hole spaced from said first hole, securing the block on a rotary block-holding table by passing a tie rod through said first hole, said table rotatable about a vertical axis, threading a saw wire through said second hole, imparting a cutting motion to said saw wire, and moving said block rotatively about said vertical axis of rotation.
Claim 5
Dependent Claim
127 words
A machine for making annular bodies from rock material blocks, said machine comprising: a bed, a rotary block-holding table mounted on said bed for rotation about a vertical axis, rod means extending along said vertical axis for securing a block to said table, motor means for rotating said table, an endless saw wire having a working run thereof stretched between two spaced pulleys, one of which pulleys is carried on said bed and the other of said pulleys supported above said table, said wire extending between said pulleys in a direction skewed from and spaced from said vertical axis of rotation, and roller means for supporting said block, said roller means positioned outwardly of said working run of said saw wire, relative to the axis of rotation.
Claim 6
Dependent Claim
