Patents by Inventor Jerry E. Trickel

Jerry E. Trickel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Die casting small parts from materials that expand when transitioning from the liquid to the solid state
    Patent number: 5782285
    Abstract: The die has first and second die halves, each die half having a plurality of cavities that, when the die halves are in a closed position, align with the cavities in the other die half, thus defining a plurality of voids that define the objects to be formed. A spacing between the front surfaces of the die halves during the injection step of the cycle helps to increase the number of parts that properly release from the die.
    Type: Grant
    Filed: January 13, 1997
    Date of Patent: July 21, 1998

  • Die casting apparatus for casting small parts from materials that expand when transitioning from the liquid to the solid state
    Patent number: 5632322
    Abstract: The die has first and second die halves, each die half having a plurality of cavities that, when the die halves are in a closed position, align with the cavities in the other die half, thus defining a plurality of voids that define the objects to be formed. Each cavity is aspherical in that the slope of the cavity is never perpendicular to the front surface of the die half, thus facilitating the removal of the objects from the die. A spacing between the front surfaces of the die halves during the injection step of the cycle helps to increase the number of parts that properly release from the die.
