Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
181 words
A grinding machine, comprising a grinding wheel, first driving means for rotating said grinding wheel at a relatively high surface speed, a pair of work piece supports for rotatably supporting a work piece for engagement with said grinding wheel, a rotatable control wheel for frictionally engaging the work piece to rotate the work piece while it is being ground, and a second driving means for rotating said control wheel at a relatively low surface speed compared with the surface speed of said grinding wheel, said control wheel including a generally cylindrical inner core portion made of a relatively soft resilient yieldable rubbery material, said control wheel including a generally cylindrical ring shaped outer peripheral portion mounted securely around said inner core portion and made of a resilient rubbery material which is substantially harder than the material of said inner core portion, the softness and resilience of said inner core portion making it possible for the control wheel to adapt itself to variations in the work piece so as to achieve full driving engagement between the work piece and said control wheel.
Claim 2
Dependent Claim
181 words
A grinding machine, comprising a grinding wheel, first driving means for rotating said grinding wheel at a relatively high surface speed, a pair of work piece supports for rotatably supporting a work piece for engagement with said grinding wheel, a rotatable control wheel for frictionally engaging the work piece to rotate the work piece while it is being ground, and a second driving means for rotating said control wheel at a relatively low surface speed compared with the surface speed of said grinding wheel, said control wheel including a generally cylindrical inner core portion made of a relatively soft resilient yieldable rubbery material, said control wheel including a generally cylindrical ring shaped outer peripheral portion mounted securely around said inner core portion and made of a resilient rubbery material which is substantially harder than the material of said inner core portion, the softness and resilience of said inner core portion making it possible for the control wheel to adapt itself to variations in the work piece so as to achieve full driving engagement between the work piece and said control wheel.
Claim 3
Dependent Claim
49 words
A grinding machine according to claim 1, in which said inner core portion and said ring shaped peripheral portion of said control wheel are made of rubber materials, said rubber material of said inner core portion being substantially softer than the rubber material of said ring shaped peripheral portion.
Claim 4
Dependent Claim
27 words
A grinding machine according to claim 1, in which said work piece supports take the form of a pair of centers for rotatably supporting the work piece.
Claim 5
Dependent Claim
72 words
A grinding machine according to claim 1, in which said inner core portion and said ring shaped outer portion of said control wheel are made of first and second different rubber materials, said first rubber material of said inner core portion being substantially softer than said second rubber material of said outer peripheral portion, said work piece supports taking the form of a pair of centers for rotatably supporting the work piece.
Claim 6
Dependent Claim
38 words
A grinding machine according to claim 4, including means for producing relative lateral adjusting movement between said work piece supporting centers and said control wheel for adjusting the driving pressure between said control wheel and the work piece.
Claim 7
Dependent Claim
37 words
A grinding machine according to claim 1, including means for producing relative lateral adjuSting movement between said control wheel and said work piece supports for adjusting the driving pressure between said control wheel and the work piece.
Claim 8
Dependent Claim
37 words
A grinding machine according to claim 1, including means for producing relative lateral adjusting movement between said work piece supports and said grinding wheel to adjust the grinding engagement between said grinding wheel and the work piece.
Claim 9
Dependent Claim
67 words
A grinding machine according to claim 1, including means for producing relative lateral adjusting movement between said work piece supports and said control wheel for adjusting the driving pressure between said control wheel and the work piece, and means for producing relative lateral adjusting movement between said work piece supports and said grinding wheel for adjusting the grinding engagement between said grinding wheel and the work piece.
