Chimney damper arrangement

Abstract

The present invention provides a new and useful arrangement for a chimney cover and damper for the outlet from the flue of a chimney which provides an open frame of substantially rectangular shape to be received on the top of the chimney defining an outlet opening from the chimney having a damper flap cooperatively and pivotably carried by the frame where the frame includes a generally channel shaped lip around the outlet end and the damper flap includes an upstanding lip to be received within the opening defined by the channel member, substantially along the length thereof, to prevent air and water from flowing over the damper flap and into the chimney. The damper flap is advantageously pivoted to assume a normally open position with respect to the frame when unrestrained and closure means which can include chain means are provided and adapted to be attached to the damper flap to pull the damper flap to a closed position with respect to the frame member when the chain is pulled. The invention can include a spring means attached to the damper flap and the chain means to provide a selected tnesion urging the damper flap toward a closed position when the chain is pulled and can further include a hammer means carried by the chain means to abruptly strike the damper flap on release of the chain means to release the damper flap if it is stuck in a closed position such as when ice, which may tend to hold the damper flap in closed position, has formed between the frame and the damper flap.
