Abstract
An apparatus for opening a shellfish (e.g. oysters and/or clams) along its seam. The apparatus is comprised of a base having (1) a knife pivotably mounted about a first axis on said base; and (2) a hammer pivotably mounted about a second axis on said base. A link slidably connects the knife to the hammer so the knife is lifted by extended upward movement of the hammer but the hammer is free to move relative of the knife during downward movement. In operation, the knife is raised by upward movement of the hammer to a height where a shellfish can be positioned below the knife. The hammer is then lowered to align knife onto the seam of the shellfish after which the hammer is dropped or pushed down to deliver an impact to the knife, causing it to penetrate the seam and open the shellfish.
Claims20
An apparatus for opening shellfish (e.g. oysters and/or clams) along the seam formed between the hinged portions of the shell of said shellfish, said apparatus comprising:
- a base;
- a support mounted on said base
- a knife pivotably mounted about a first axis on said support and movable between a first position where said knife rests on said seam of said shellfish when said shellfish is in an operable position on said base and a second position where said knife will penetrate said seam of said shellfish to thereby open said shellfish;
- and
- hammer means pivotably mounted about a second axis on said support and movable between a first position where said hammer means lies above said knife and a second position where said hammer means will deliver an impact to said knife to thereby drive said knife to its second position.
An apparatus for opening shellfish (e.g. oysters and/or clams) along the seam naturally-occurring between the hinged portions of the shell of said shellfish, said apparatus comprising:
- a retangular base plate;
- a support secured near one end of the upper surface of said base plate and extending upward therefrom;
- a knife pivotably mounted on said support about a first axis and movable between a first position where said knife rests on said seam of said shellfish when said shellfish is in an operable position on said base and a second position where said knife will penetrate said seam of said shellfish to thereby open said shellfish;
- and
- hammer means pivotably mounted on said support about a second axis base and movable between a first position where said hammer means lies above said knife and a second position where said hammer means will deliver an impact to said knife to thereby drive said knife to its second position.
