Key to Links for Patent Information

USPTO = U.S. Patent Office . Images of the actual patent can be viewed on the U.S. Patent Office web site but a special TIFF viewer must be installed with your browser in order properly work. More information on how to configure your computer to view these patents can be found at TIFF image Viewers for Patent Images.
DATAMP = Directory of American Tool And Machinery Patents . A sister site to VintageMachinery.org with information on patents related to machinery and tools. A much easier user interface than the USPTO's for finding information on machinery patents.

4,399,603 Aug. 23, 1983 Power Grip Tool Exchange Arm for Machining Center Robert E. Reed Kaukauna, WI Abstract
An improved tool exchange arm for use in the automatic tool changer of a machining center adapted for boring, drilling, milling, tapping and tool changing operations under numerical control. The tool exchange arm may be incorporated in machining centers of either vertical or horizontal spindle configuration. It operates with current commercial tapered shank toolholders, is capable of precisely and securely positioning itself for engagement with the toolholders to be exchanged, and rotates quickly for tool exchange without sharp impacts at the extremities of its rotational stroke.
