Claims
- 1. A doctor blade extractor comprising:a head portion including at least one gripping member; a linkage shaft slidably disposed in a hollow shaft and coupled to said at least one gripping member, said linkage shaft being movable between a closed position wherein said at least one gripping member is positioned to engage a doctor blade, and an open position wherein said at least one gripping member is positioned to release said doctor blade; and a locking member for releasably locking said linkage shaft in said closed position, said locking member comprising a locking ring having threads thereon for meshingly engaging corresponding threads on an interior of said hollow shaft, said locking ring being rotatable into said hollow shaft for engaging said linkage shaft in said closed position.
- 2. The doctor blade extractor of claim 1, wherein at least one gripping member comprises a pivoting cam shoe coupled to said linkage shaft through a pin.
- 3. The doctor blade extractor of claim 2, wherein said head portion further comprises a stationary platform shoe, and wherein said cam shoe is adapted for forcing said doctor blade against said platform shoe when said linkage arm is in said closed position.
- 4. The doctor blade extractor of claim 1, wherein said head portion comprises a yoke coupled to said linkage shaft and first and second pivot arms coupled to said yoke, said pivot arms being attached to associated first and second gripping members.
- 5. The doctor blade extractor of claim 4, wherein said first and second gripping members are fixed about first and second associated pins, said pins having portions disposed in associated slots in said head portion.
- 6. A doctor blade extractor comprising:a head portion including at least one gripping member; a linkage shaft slidably disposed in a hollow shaft and coupled to said at least one gripping member, said linkage shaft being movable between a closed position wherein said at least one gripping member is positioned to engage a doctor blade, and an open position wherein said at least one gripping member is positioned to release said doctor blade; a locking member for releasably locking said linkage shaft in said closed position; and a trigger for moving said linkage shaft between said open and closed positions, said trigger extending from said linkage shaft through a slot in said hollow shaft.
- 7. A doctor blade extractor comprising:a head portion including at least one gripping member; a linkage shaft coupled to said at least one gripping member, said linkage shaft being movable between a closed position wherein said at least one gripping member is positioned to engage a doctor blade, and an open position wherein said at least one gripping member is positioned to release said doctor blade; a locking member for releasably locking said linkage shaft in said closed position; and a spring coupled to said linkage shaft for biasing said linkage shaft into said closed position.
- 8. A doctor blade extractor comprising:a head portion comprising a pivoting cam shoe; and a linkage shaft slidably disposed in a hollow shaft and coupled to said pivoting cam shoe through a pin, said linkage shaft being movable in said hollow shaft between a closed position wherein said cam shoe is positioned to engage a doctor blade, and an open position wherein said cam shoe is positioned to release said doctor blade.
- 9. The doctor blade extractor of claim 8, wherein a trigger for moving said linkage shaft between said open and closed positions extends from said linkage shaft through a slot in said hollow shaft.
- 10. The doctor blade extractor of claim 8, wherein said head portion further comprises a stationary platform shoe, and wherein said cam shoe is adapted for forcing said doctor blade against said platform shoe when said linkage arm is in said closed position.
- 11. A doctor blade extractor comprising:a head portion comprising a yoke and first and second pivot arms coupled to said yoke, each of said pivot arms being attached to an associated one of first and second gripping members; and a linkage shaft coupled to said yoke, said linkage shaft being movable between a closed position wherein said first and second gripping members are positioned to engage a doctor blade, and an open position wherein said first and second gripping members are positioned to release said doctor blade, wherein said first and second gripping members are fixed about first and second associated pins, said pins having portions disposed in associated slots in said head portion.
- 12. The doctor blade extractor of claim 11, wherein said linkage shaft is slidably disposed in a hollow shaft and is movable in said hollow shaft between said closed position and said open position.
- 13. A doctor blade extractor comprising:a head portion comprising a yoke and first and second pivot arms coupled to said yoke, each of said pivot arms being attached to an associated one of first and second gripping members; a linkage shaft slidably disposed in a hollow shaft and coupled to said yoke, said linkage shaft being movable in said hollow shaft between a closed position wherein said first and second gripping members are positioned to engage a doctor blade, and an open position wherein said first and second gripping members are positioned to release said doctor blade; and a trigger for moving said linkage shaft between said open and closed positions, said trigger extending from said linkage shaft through a slot in said hollow shaft.
