TODAY’S PATENT – CHIMNEY CLEANING BRUSH
Cleanliness is the key to a safe and protective environment. In today’s patent, we will talk about Harvey J. Weir’s invention, “Chimney cleaning brush” (US4562608A), which was patented by the USPTO on 7th January 1986.
This invention relates to a brush apparatus for cleaning chimneys which can be passed in one direction through a chimney in a folded configuration and subsequently passed through the chimney in the other direction in an unfolded cleaning configuration. There were various prior art inventions that were differently manufactured, primarily used for cleaning the chimney walls.
The present improved invention is a simpler construction which is disclosed in the prior art, albeit as effective in operation. This apparatus is passed in one direction through the chimney walls in a folded configuration. They also clean the edges of the walls in a systematic manner.
