Cooling and drying fins for brake drums and flywheels

An apparatus for drying and cooling a brake drum including a generally upright annular exterior wall having axially interior and exterior surfaces and a generally cylindrical wall extended interiorly from the outer periphery of the exterior wall, said apparatus comprising,

• a generally circular elongated flexible strip,
• means for securing said strip on the interior surface of said exterior wall adjacent said cylindrical wall, and a plurality of fins on said strip, said fins being arranged in circumferentially spaced relation thereon and so shaped and positioned for causing air flow generally outwardly from said fins toward said cylindrical wall in response to rotation of the brake drum in one direction,
• each fin comprising a projection defining a raised socket having an open substantially radially extending leading side, a closed substantially radially extending trailing side and radially inner and outer ends, said open leading side being arranged ahead of said closed trailing side with reference to rotation in said one direction and the outer end being at least partially open for substantially radially exhausting collected air in response to rotation of the strip in said one direction,
• said outer end of each socket having circumferentially spaced leading and trailing ends with respect to rotation in said one direction, said leading end contacting the strip to prevent air flow therethrough and said trailing end defining said partial opening for passage of air flow therethrough.
