Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
123 words
In combination with a machine having tools operating upon a bar from which the work article is formed including a tube through which the bar is fed, a chuck for gripping the bar, a non-metallic resilient member of a size to slidably frictionally fit the tube and having a central opening with walls slidably frictionally gripping said bar to a degree greater than the frictional fit of said member in said tube so as to move and rotate therewith as the bar is fed, means for feeding the bar to cause said member to move with the bar through the tube toward said chuck, a stop to engage said member and cause the bar to move through said member as further feeding occurs.
Claim 2
Dependent Claim
123 words
