Abstract
A mechanical apparatus is disclosed, consisting of a platform for attaching tools to crack shellfish claws and shellfish body parts also for opening clams and oysters. The device is comprised of a rotating lever to which hand force is applied, and attached to coupling bars that are attached to a second lever and a blade that is attached and driven into a clam or oyster trapped between the lower plate and the blade. A shellfish claw or shellfish body part is cracked when trapped between a fixed bar and a rotating lever.
Claims1
A shellfish shucking and cracking machine comprising:
- a horizontal base with a pad;
- a pair of front and rear vertical supports mounted on the upper surface of said base and oriented parallel to each other;
- a main lever pivotally mounted to and between the front pair of vertical supports near the top ends thereof;
- a pair of link bars pivotally attached to one end to the main lever at a location proximate to the main lever pivotal connection to the front vertical supports;
- said link bars being oriented parallel to each other with one of said link bars positioned on either side on said main lever;
- a fixed support cross-link mounted to and between said front and rear pairs of vertical supports;
- said fixed support cross-link being positioned above and parallel to the base to provide a support surface for a first shellfish body portion;
- an input lever pivotally attached to and between the rear vertical supports and the free ends of the link bars, at opposite ends thereof;
- said input lever being positioned above said fixed support cross-link at a distance, whereby said input lever contacts and cracks open the shellfish body portion positioned on said cross-link support when a downward force is applied to the input lever by said main lever via the link bars;
- a blade mounted to the input lever at the end proximate the link bar connection and above the pad for opening a second shellfish body portion supported on said pad, when a downward force is applied by the main lever to the input lever.
