  The Carr Tool Holder, built by Carr Bros. of Syracuse, N. Y., and described in the new tools department of the November, 1907, issue of Machinery, has recently been improved by the provision of arrangement for adjusting the height of the tool post without losing any of the rigidity that characterizes the older form. It has also been adapted to the use of turning and boring tools, as well as side tools.
