Abstract: An apparatus for a damper cap for a chimney flue includes a top plate having dimensions conforming to a top of the chimney flue. A bird and animal screen is joined to and extends from a bottom of the top plate. The screen has dimensions for insertion into the chimney flue. A rod joined to a center of the top plate extends downward into the chimney flue. A support structure is secured to an interior of the chimney flue. A mechanism is joined to the support structure and the rod for moving the rod in a vertical direction. In an open position the top plate is above the chimney flue to allow smoke to exit and the screen restricts birds and animals from entering. In a closed position the top plate is proximate the chimney flue restricting airflow into and out of the chimney flue and the apparatus is retracted into the flue.

Abstract: A combination chimney top spark arrester and damper is provided wherein the damper is positioned within the spark arrester. The damper moves between a closed position in which it covers the top of the chimney flue and an open position in which it is raised above the top of the chimney to allow full, unobstructed flow of flue gases. An actuator includes a counterweight urging the damper into its open position. The actuator allows the user to close the damper and to apply a tensioning force to the closed damper to resist vibration and chattering. The device is quickly installed and fits several different chimney sizes.

Abstract: A chimney damper and chimney cap system comprised of a support base securable to the top of a chimney flue, a bracket assembly and spring assembly secured to the support base, a chimney cap secured to the bracket assembly wherein the bracket assembly bias the chimney cap to an open position, a damper cable secured to a pin secured to the bottom surface of the chimney cap, a support arm secured to the support base for supporting the damper cable within the chimney flue and a lever assembly secured to the support arm to open the chimney cap if it is stuck shut.

Abstract: chimney damper and chimney cap system comprised of a support base securable to the top of a chimney flue, a support frame secured to the support base extending above the support base, a chimney cap secured to the top of the frame, a bracket and spring assembly secured to the bottom portion of the chimney cap, a chimney damper cover plate secured to the bracket and spring assembly wherein the bracket and spring assembly biases the cover plate to an open position, a damper cable secured to the bottom portion of the chimney damper cover plate and a support arm secured to the support base for supporting the damper cable within the chimney flue.

Abstract: A chimney cap to selectively cover the outlet from the flue of a chimney which includes an open frame of selected geometric configuration located at the top of the chimney flue around the outlet, a cap to substantially cover the opening defined by the frame, bias device to bias the cap to a position separated by the frame, where a seal is provided to seal the cap and the frame when the cap is located contiguous to the frame. A guide arrangement can be provided to guide the cap toward the frame to selectively locate the seal of the cap and seal surface of the frame. A draw device can be provided to pass through the chimney flue to allow the cap to be drawn to engagement with the frame and a latch can be provided to receive the draw device to hold the cap in engagement with the frame against the bias force.
