Abstract: A chimney liner adaptor is provided to allow air to flow between the outside environment and an annular space in a lined chimney flue. The adaptor may allow an air cooling system to operate but prevents undesirable elements from entering the annular space. The liner adaptor may be disposed between the chimney cap and the top walls of the chimney system and around the chimney liner. The adaptor may include perforated material, such as an expanded metal mesh, a metal screen, stamped metal screen, rugged netting, or the like. The perforated material permits gas flow, provides structural support for other elements of the adaptor, and filters out undesirable objects from entering the chimney.

Abstract: A chimney cover that allows complete and unrestricted access to the chimney and flue liner without the necessity of removing any major component of the chimney cover from the chimney. The lid and spark arrestor cage are permanently secured together and then hinged in a suitable manner to a mounting frame that is secured to the chimney or to the flue liner. A positive locking device is provided so that the hinged lid and spark arrestor cage can be securely locked to the frame but easily unlocked so that the lid and cage can be swung out of the way to allow complete and unrestricted access to the chimney and flue.

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.

Abstract: A stackable chimney cap includes a stackable cage/base unit composed of four parts, each part being formed by bending from a blank of metal sheet and the four parts being permanently joined together by weldments. Trapezoidal-shaped, perforated side walls of the four parts together form a pyramidal cage portion of the cage/base unit having a rectangular opening at a planar base edge thereof. Bent flange portions on each part together form a peripheral mounting base portion of the chimney cap that extends outwardly from the base edge of the cage portion with respect to the base opening. A stackable hood separate from the cage/base unit is attached to the upper edge of the cage portion at the point of sale or use of the chimney cap. Several chimney caps, with the cage/base units and hoods stacked separately, can be boxed together for storage, shipment and retail stocking, using a fraction of the space required for the same number of fully assembled chimney caps of the same size.

Abstract: A detachable chimney cap hood which can be attached to the side walls of a chimney cap without the need for nuts, bolts, screws or tools and allows the hood to be later removed manually. The hood includes a cover portion and one or more locking clips attached to the cover portion. Guide pieces can also be included to align the hood onto the chimney cap. The locking clips and guide pieces hold the hood in place. The hood allows a person to attach and remove the hood manually without a wrench or other tool when a chimney flue needs to be cleaned. This feature is especially desirable when the chimney cap is cemented or otherwise permanently affixed to the chimney flue because the hood of the chimney cap must be separately removed in order to access the one or more chimney flues covered by the cap.

Abstract: A collapsible chimney cap which is stored in separate components and assembled at the point of installation. The connections between the separate pieces when assembled form smooth corners without external metal protrusions which could injure an installer or other person near the chimney cap. The chimney cap's connection mechanism also strengthens the assembled chimney cap by providing multiple points of connection. Each side piece has a insertion portion with internal protrusions which fits inside a receiving portion of an adjacent side piece. A roof is then attached the side pieces to complete the chimney cap.

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.
