Patent ID: 8418275

Claim:
A system for unclogging toilets, comprising: a hollow tube having opposed upper and lower ends, the upper and lower ends being closed, the upper end having a port formed therethrough, the lower end having a pair of peripheral apertures and a central aperture formed therethrough, the hollow tube being adapted for mounting on a toilet so that the pair of peripheral apertures and the central aperture are in communication with an interior of a bend of a toilet outflow pipe; a pair of conduits diametrically positioned within the hollow tube and mounted to an interior wall thereof, each of the conduits having open upper and lower ends, the upper ends of the conduits being located within the hollow tube, the lower ends of the conduits extending through a respective one of the peripheral apertures in the hollow tube; a plunger slidably mounted within the hollow tube, the plunger having a pair of diametrically opposed recesses formed in a peripheral edge thereof for respectively receiving the pair of conduits, the plunger having a central opening formed therethrough, the plunger forming a fluid-tight seal with the hollow tube and external walls of the pair of conduits; an expandable bladder having opposed fixed and free ends, the fixed end being open and the free end being closed, the fixed end being secured to a lower surface of the plunger about the central opening formed therethrough, the free end extending through the central aperture of the lower end of the hollow tube; and means for delivering pressurized air to the interior of the hollow tube through the port formed through the upper end of the hollow tube so that the plunger may be selectively driven downward within the hollow tube while simultaneously filling the expandable bladder and driving the pressurized air through the pair of conduits into the toilet outflow pipe; whereby the expandable bladder expands to form a fluid-tight barrier separating opposed sides of the bend of the toilet outflow pipe so that the pressurized air flowing through the pair of conduits breaks up clogs formed on either side of the bend of the toilet outflow pipe when the pressurized air is delivered to the interior of the hollow tube.
