Patent for "valves which will allow all the water to flow out of the popes to a position below freezing-point after each application of water, whether the water is used in a closet-cistern or drawn out of a hudrant or other application is made, and to arrange the valves so that the supply-valves will be automatically closed by water-pressure in connection with the operation of a siphon in a closet-cistern and the waste-valve will be closed by the pressure of water, siphonic action, or both, when the supply-valves are opened."
