Abstract
A sealing mechanism acts between a quick-change tool holder and a tool adapter receivable therein. The sealing mechanism is an elastomer seal in the form of a V-flange elastomer seal ring mounted on a metal member which has a coaxial cylindrical outer surface and an axially inwardly facing shoulder to establish the elastomer seal member in position. This seal member has a generally conical seal member first portion with an external peripheral surface engaging a planar surface on the quick-change tool holder. This prevents contaminants, such as fine chips, from entering the interior of the quick-change tool holder. The foregoing abstract is merely a resume of the one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
