  • Patent number: 4984309
    Abstract: A shower or bathtub drain system (10,60) in which a sealing ring (16,16') is fastened to one end of a strainer body (32) or shoe (64) and inserted through the drain hole (14,58) in the bottom of the shower or bathtub from the space below the bottom surface. The sealing ring (16,16') is of a resilient material and has an upper flange (18,18') for overlapping the surfaces (20,62) at the edges of the drain hole. The installation is completed from the space above the bottom plate member (12,56) of the bathtub or shower by positioning a clamp ring (40,68) over the sealing ring flange (18,18') and then pulling the clamp ring (40,68) toward the strainer body (32) or shoe (64) by screw connectors (52,78) inserted through holes (48,80) in the clamp ring (40,68) and threaded in holes (50,76) in the strainer body (32) or shoe (64).

  • Patent number: 4644970
    Abstract: A mixing faucet assembly especially adaptable for frostfree installation has a casing with a mixing chamber containing valve means for controlling the flow of hot and cold water into the chamber. The mixed water is conveyed from the mixing chamber to a tubular member having a nozzle spaced from the casing. A control rod is connected to the valve means and extends through the tubular member to a single handle control adjacent to the nozzle so that upon rotation of the control rod hot and cold water is selectively metered into the mixing chamber and from there communicated to the nozzle. The control rod may be detachedly connected to the valve means at the casing and the casing may be detachably connected to the tubular member for servicing the faucet assembly from the inside of a building.
