ABSTRACT:
Apparatus for automatically returning a hinged toilet seat to the lower horizontal position after use of the toilet as a urinal by a male. An operating cylinder is easily attached to the toilet by an adjustable mounting system. A piston is reciprocally disposed in the cylinder and operably linked by a pivoting lever mechanism to the pivoted toilet seat. Movement of the toilet seat to the upper position actuates a biasing spring to urge the piston to move to return the seat to the lower position. The biased piston movement is retarded by operating fluid in the cylinder to delay closing until the male user is finished.
