Claim 1
Independent Claim
135 words
A cylindrical transfer sleeve having a bore therethrough responsive to a radially directed force comprising a first annular work engaging surface, a second annular force receiving surface, and a plurality of slots radially extending from said second surface toward said first surface, said slots terminating a predetermined distance from said first surface to leave an expandable cross section of material adjacent said first surface, a plurality of apertures laterally extending the length of the transfer sleeve, each of said slots terminating in one of said apertures wherein each aperture defines one limit of the expandable cross section of material, said expandable cross section being the distance between said aperture and said first surface, and defined as the sum of 0.060 inch plus 0.030 (D-1) wherein D is the outside diameter of the sleeve in inches.
