By Biased Breaking Member Patents (Class 99/577)
  • Patent number: 10130217
    Abstract: A nut cracking device with a frame having elongated, parallel members that surround a mechanical advantage device, such as a hydraulic jack. Top and bottom channel members are mounted at opposite ends of the frame members to separate the frame members and form a rigid frame structure. An anvil with texture to reduce slipping and increase pressure is mounted to the top member and extends toward the jack, on which a table is mounted. A nut may be placed on the table. Upon displacement of the jack's shaft, the table moves toward the anvil and any nut on the table is clamped, and ultimately fractured, between the table and the anvil. A hand-grippable knob permits manual bypass of a valve to permit the table to be pulled away from the anvil by springs mounted to the table.

  • Patent number: 8522676
    Abstract: A gravity-induced impact-type nutcracker with a self-guided trip hammer that, upon actuation, drops solely via the force of gravity to strike a nut supported within a nut cracking chamber with a consistently guided uniform force. The helve of the hammer is pivotally supported adjacent its rear end between a pair of upstanding guide columns. A cord connected to the rear of the hammer helve is attached to a freewheeling take-up spool which is releasably engagable by a hand crank drive wheel to facilitate raising the hammer head to a set position prior to releasing the same. Continued rotation of the crank causes a release mechanism connected to the rear of the hammer helve to disengage the take-up spool from the drive wheel, thereby releasing and allowing the hammer to drop under its own weight. The cracking chamber which holds the nut includes a removable drawer with a variety of differently sized nut-retaining cavities formed therein for accommodating a variety of different types and sizes of nuts.

  • Publication number: 20130177681
    Abstract: An egg shell removal device that comprises a handheld, oscillating assembly having a body member and an electrically driven attachment head. The head comprises a formed member driven by an oscillating output shaft from the body member, which provides a means to separate the shell and the inner and outer membranes from an egg white without damaging the egg white in the process. The head is a tapering section having a rounded tip, a concave interior surface, and a convex outer surface, whereby the interior surface travels along the egg white surface and contours thereto, while the outer surface lifts and breaks the shell as the head member oscillates from its oscillator or electric motor input. Also disclosed is an accompanying method of egg shell removal using a handheld, vibratory device to lift and break a shell from an egg white, which replaces traditional shell removal process conducted by hand.

  • Patent number: 8069779
    Abstract: A device for cracking open an egg is shown, having egg-size sensing means for determining the size of an egg positioned in the device, thereby providing for automatic calibration of the device to the specific size of an egg to be cracked. The calibration determines how much would the distance between the piercing members and the imaginary longitudinal axis of the egg be reduced before the piercing members stop their advancing towards the egg and start moving apart for cracking its shell open. The device can thus open eggs of different sizes, e.g. having widths between 40 and 50 millimeters, accurately without requiring special preparation or manual calibration. A method for cracking open an egg based on said device is also shown.

  • Patent number: 6035772
    Abstract: An apparatus for cracking nuts is disclosed which employs a striker mechanism to apply a sharp force to the shell of a nut in order to fracture it. The nut is held in a chamber consisting of an anvil and a cup, with a spring-loaded striker being cocked and released by the single motion of a lever. In the lever's normal raised state, the anvil and cup are separated to allow for insertion of the uncracked nut. As the lever is lowered, the anvil is gently closed down upon the nut to secure it with a light force between the anvil and the cup. As the lever continues its travel downward, the striker is cocked and released, imparting an impulse force on the cup and the nut, thereby cracking the shell of the nut with a predetermined force independent of the size of the nut. A fragment shield integral to the lever is lowered into place along either side of the cracking chamber as the lever is lowered, providing a simple and reliable safety mechanism.
