  • Patent number: 6066039
    Abstract: A chimney cover is provided which can accommodate any size chimney. The chimney cover comprises at least one panel assembly that is attached to the chimney by weaving a strap through slots formed in the ends of the panel and by connecting the ends of the strap to a fastener which can be adjusted to tighten the strap about the chimney. The chimney cover preferably is comprised of a plurality of subassemblies, each of which comprises two side panels and a middle panel. The first ends of the side panels are movably mounted within a guide structure formed in the middle panel to allow the side panels to slide in first and second directions within the guide structure. The overall length of the subassemblies can be adjusted by sliding the panels in the first or second directions. Once the length of the subassemblies has been fixed, the side panels are locked in place. The subassemblies are then placed in an overlapping relationship and adjacent side panels are attached at their second ends.

  • Patent number: 5842918
    Abstract: An adjustable chimney cover is provided which can be adjusted in length and width to accommodate any size chimney. The chimney cover is comprised of a plurality of subassemblies, each of which comprises two side panels and a middle panel. The first ends of the side panels are movably mounted within a guide structure formed in the middle panel to allow the side panels to slide in first and second directions within the guide structure. The overall length of the subassemblies can be adjusted by sliding the panels in the first or second directions. Once the length of the subassemblies has been fixed, the side panels are locked in place. The subassemblies are then placed in an overlapping relationship and adjacent side panels are attached at their second ends. The second ends of the side panels are then attached to a chimney. In order to adjust the width of the chimney cover, additional side panels are used and/or the amount of overlap between the subassemblies is adjusted.

  • Patent number: 5647046
    Abstract: An apparatus, called a wedge deadend, used to secure aerial fiber optic transmission lines or cables. The deadend and secured cable can effectively be attached to support structures such as poles or towers. The wedge deadend has a single assembled frame with an attaching cable for mounting to the support structure and two wedges that slide into the frame. The frame consists of two parallel plates. Each plate has two slots that are tapered and angled toward one another. The wedges are similarly tapered enabling them to be interlocked with the side plates. Both wedges also have a groove that is sized and textured to grip a specified cable. The wedges can be designed to compress the encased cable evenly along the entire contact surface of the wedge, or with varying force along such surface.
