  • Patent number: 8169293
    Abstract: The fuse element retaining device is an L-shaped bracket having a long leg and a short leg. The short leg has a notch and a plurality of vent holes surrounding the notch. At least one clip is provided for mounting the long leg of the L-shaped bracket to a fuse holder barrel. The fuse holder barrel has a top end and a bottom end. When the long leg of the L-shaped bracket is mounted to the fuse holder barrel, the short leg is positioned with the vent holes over the bottom end of the fuse holder barrel. The vent holes are for venting propellant gases during a discharge when a fuse element blows. The notch receives a part of the fuse element from the fuse holder barrel and minimizes projectiles from the fuse element heading towards the ground at very high speeds when the fuse element blows during the discharge.

  • Patent number: 5134382
    Abstract: This support is for mounting on structure of electrical apparatus a fuse or other device that comprises a cylindrical tube. The support comprises a base adapted to be secured to said structure, the base having a length and a width dimension. Two legs project laterally from the base at its longitudinally-opposite ends, each leg comprising a body portion that has a proximate end and a distal end. The base and the legs are of rigid polymeric insulating material, and the body portion of each leg is integrally joined to the base at the proximate end of the body portion. At its distal end the body portion of each leg carries a flange that projects from the body portion longitudinally with respect to the base. Each flange has a concave arcuate surface facing away from the base that is adapted to receive a portion of the above cylindrical tube. The arcuate surface includes a first curved portion for receiving a relatively large diameter tube and another curved portion for receiving a relatively small diameter tube.
