  • Trench plate connector
    Patent number: 6612631
    Abstract: A trench plate connector comprising a large-diameter skirt member for dissipating lateral forces, applied onto the trench plate connector, is disclosed. The large-diameter skirt member is threaded onto a stud, and can be locked onto the stud with a nut. Once the large-diameter skirt member is locked into place, one or more arms of the large-diameter skirt member can be used to apply rotational forces onto the trench plate connector to thereby secure or remove the stud of the trench plate connector from the trench plate. Each arm of the large-diameter skirt member can be impacted with a hammer, for example, to apply substantial rotational forces onto the trench plate connector for tightening or removal thereof. A unique double-threaded stud is used to accommodate the large-diameter skirt member. The double-threaded stud comprises a first thread on one end for being threaded into a trench plate, and a second thread on the other end for accommodating both the large-diameter skirt member and a securing nut.

  • Forged trench plate connector
    Patent number: 6578889
    Abstract: A forged trench plate connector having a forged steel unitary eye member and a large-diameter skirt member for dissipating lateral forces, applied onto the trench plate connector, is disclosed. The large-diameter skirt member is threaded onto a double-threaded stud used to accommodate the large-diameter skirt member. The double-threaded stud comprises a first thread on one end for being threaded into a trench plate, and a second thread on the other end for accommodating both the large-diameter skirt member and a securing nut. Once the large-diameter skirt member is locked into place, one or more arms of the large-diameter skirt member can be used to apply rotational forces onto the trench plate connector to thereby secure or remove the stud of the trench plate connector from the trench plate.

  • Unitary eye bolt
    Patent number: 6398447
    Abstract: A unitary eye bolt comprising a large-diameter skirt member for dissipating lateral forces, applied onto the unitary eye bolt, is disclosed. The large-diameter skirt member is threaded onto a stud, and can be locked onto the stud with a nut. Once the large-diameter skirt member is locked into place, one or more arms of the large-diameter skirt member can be used to apply rotational forces onto the unitary eye bolt to thereby secure or remove the stud of the unitary eye bolt from the trench plate. Each arm of the large-diameter skirt member can be impacted with a hammer, for example, to apply substantial rotational forces onto the unitary eye bolt for tightening or removal thereof. A unique double-threaded stud is used to accommodate the large-diameter skirt member. The double-threaded stud comprises a first thread on one end for being threaded into a trench plate, and a second thread on the other end for accommodating both the large-diameter skirt member and a securing nut.
