Total Claims: 9
Claim 1
Independent Claim
239 words
In combination with a toilet and a lavatory, said toilet having a toilet bowl and a toilet seat, said toilet seat being pivotally connected by pivot means to said toilet bowl, said lavatory having a liquid drain pipe, a toilet ventilating apparatus comprising: air duct means connected to said toilet seat; air conduit means connected to said air duct means; air blower means having an air inlet and a air outlet, said air inlet connected to said air duct means, said air outlet connected to said lavatory liquid drain pipe, whereby said air blower means is to draw air by suction from within said toilet bowl through air duct means and through said air conduit means and into said lavatory liquid drain pipe; means connected to said toilet seat for causing said toilet seat to assume a canted position with respect to the rim of the said toilet bowl when said seat is in the at rest position; said means includes an axle, said seat being pivotally mounted upon said axle, said axle being fixed to connected anchor means, said anchor means including an anchor bearing, said anchor bearing being movable between an and upper position and a lower position, said anchor bearing being under a constant bias to said upper position, whereby when said anchor bearing is in said upper position said toilet seat is canted at an angle with respect to the rim of said toilet bowl.
