Impeller puller

To be used to remove flexible impellers of varying dimensions from a shaft, an impeller puller comprising:

• a linkage head, said linkage head including an axial bore extending therethrough,
• at least two clamp members, said clamp members being oppositely disposed from one another on opposite sides of said linkage head,
• a plurality of elongate link members,
• at least two of said link members being hingedly disposed between said linkage head and a first of said clamp members such that said first clamp member is hingedly movable between a retracted and a clamping position,
• at least two of said link members being hingedly disposed between said linkage head and a second of said clamp members such that said second clamp member is hingedly movable between a retracted and a clamping position,
• said first and said second clamp members each including at least one gripping jaw, said gripping jaws on each of said clamp members including confronting toothed inner surfaces structured and disposed to securely grip the impeller,
• adjustment means structured and disposed to adjustably and removably position said gripping jaws on said clamp members such that a length between said confronting toothed inner surfaces is varied to accommodate impellers of varying sizes and configurations,
• each of said clamp members including an outwardly extending handle segment structure and disposed to enable said clamp members to be easily and fully held, utilizing one hand, in said retracted position during attachment positioning and removal of said gripping jaws from the impeller,
• an elongate screw member extending axially through said axial bore of said linkage head, said screw member being adjustably positionable therein so as to contact the shaft upon which the flexible impeller is disposed, and
• said screw member being structured and disposed to be inwardly screwed towards the shaft such that contact by said screw member with the shaft will result in said linkage head moving away from the shaft and accordingly the impeller gripped between said gripping jaws being pulled from the shaft.
