The cylinder constitutes a unitary structure held together by 20 at its outer end is provided with an outwardly the exible sleeve 36. This structure may be apextending fiange 22 in the periphery of whichk are plied endwise over the shaft I8 and clamped in formed holes 24 to accommodate a wrench for position by the screw I2. The bufiing sleeve 48 45 turning the cylinder 20 upon the tubular portion may thenbe applied endwise over the sleeve 36. I6. A second support 26 has a tubular portion 28 In order to insure an internal .gripping pressure surrounding the portion I6 and the cylinder 20. against the bufiing sleeve, the cushion 48 is then The tubular portion I6 is of enlarged external inflated. In operation the bulging of the flexible diameter at a locality between the flange I8 and sleeve 36 under the pressure of the inflated cush- 50 the adjacent end of the cylinder 20 to provide a ion 44 is sufficient to insure rotation of the buiiing bearing surface 30 for the end of the tubular porsleeve 48 with the tool body.

A key 3l extending inwardly from the work against the tool is sustained not only by member 28 engages a corresponding slot in the the air pressure within the cushion 44 but also by member I4 to prevent relative rotation. The rethe tension induced in the iiexible sleeve 36 by 55 the spring 5U which enables theA operator to bear with considerable pressure against the Work Without danger of collapsing the sleeve 3S. The thrust of the spring 50 may be increased or diminished as desired by turning the flange 22 with a suitable Wrench.
Having thus described the invention, what I claim as new and desire to secure by Letters Patent of the United States is:
