Description: |
| Abstract:
In Reissue Patent No. RE17,259 of April 09, 1929, granted to Claude W. Bennett, is disclosed a new and novel type of tool holder in which a tool was clamped in the tool holder by wedge members, the movement of one of the wedge members being used to clamp the tool, and the movement of another of the wedge members being used to release the tool. In inserting and removing a tool from a tool holder of this class, it is desirable to have considerable clearance between the tool and the wedge members as this prevents the 'a wedge members from interfering with the insertion and removal of the tool. It is an object of our invention to provide a tool holder in which a large clearance is provided between the wedge members and the tool when the wedge members are in the releasing position.
Claim:
In a tool holder, the combination of: a tool body adapted to receive a tool; wedge means operable to clamp said tool in said tool body; toothed projections on said wedge means; a backing means held by said tool body; and toothed projections on said backing means cooperating with said toothed projections on said wedge means whereby a small movement of said wedge means in a wedging direction will produce a relatively large wedging action. |
