Ablutionary appliances

Claim 2

An ablutionary appliance comprising a water catchment member having an uncontrolled waste outlet so that water cannot be retained in said catchment member, a water delivery pipe having an outlet end disposed above said catchment member, adjustable mounting means for said water delivery pipe for adjusting said outlet end to any one of a range of predetermined positions above said catchment member, a substantially spherical head mounted on said outlet end and having a through passage communicating with the interior of said water delivery pipe, a substantially cylindrical sleeve mounted on said head, a substantially cylindrical liner located and seated within said sleeve and said liner engaging with said head for swivelling movement of said liner and said sleeve relative to said head, an internal bore in said liner communicating with said through passage, a valve cup received within said liner for rotation relative to the axis of said liner between two extreme positions spaced 180* apart, first and second diametrically opposed ports of different crosssectional areas formed in said valve cup, a chamber extending between said sleeve and said liner, said chamber having an entrance through a port formed in said liner arranged to register with one or other of said first and second valve cup ports depending on said extreme position of rotation of said valve cup, a nozzle body mounted on said sleeve for relative rotation and defining an outlet passage communicating with said chamber, means on said nozzle body engaging with said valve cup for rotating said valve cup in response to rotation of said nozzle body, and an apertured wall of said nozzle body terminating said outlet passage, whereby said nozzle body may be swivelled and rotated to change the trajectory of water discharged through said wall, and on rotation, when the valve cup is at the first of said extreme positions flow is at a maximum, and when said valve cup is at the second of said extreme positions flow is restricted, whilst during rotation between said first and second extreme positions any substantial flow is prevented.

Claim 3

An ablutionary appliance according to claim 1 wherein said apertured wall of said nozzle body extends in a plane inclined to the axis of rotation of said nozzle body and is constituted by at least one perforated element detachably secured to said nozzle body.

Claim 4

An ablutionary appliance according to claim 2 wherein said means for rotating said valve cup in response to rotation of said nozzle body comprises interengaging vanes and recesses.

Claim 5

An ablutionary appliance according to claim 3 wherein said adjustable mounting means for said water delivery pipe comprises knuckle couplings having hinge axes extending normal to said water delivery pipe.

Claim 6

An ablutionary appliance comprising a water catchment member having an uncontrolled waste outlet so that water cannot be retained in said catchment member, a water delivery pipe having an outlet disposed above said catchment member, a bush through which said water delivery pipe is displaceable lengthwise for adjusting said outlet end to any one of a range of predetermined positions above said catchment member, an intermediate pipe having one end connected to said bush and within which said water delivery pipe may be displaced, a connection at the other end of said intermediate pipe for connection to a water supply pipe, a substantially spherical head mounted on said outlet end and having a through passage communicating with the interior of said water delivery pipe, a substantially cylindrical sleeve mounted on said head, a substantially cylindrical liner located and seated within said sleeve and said liner engaging with said head for swivelling movement of said liner and said sleeve relative to said head, an internal bore in said liner communicating with said through passage, a valve cup received within said liner for rotation relative to the axis of said liner between two extreme positions spaced 180* apart, first and second diametrically opposed ports of different cross-sectional areas formed in said valve cup, a chamber extending between said sleeve and said liner, said chamber having an entrance through a port formed in said liner arranged to register with one or other of said first and second extreme positions of rotation of said valve cup, a nozzle body mounted on said sleeve for relative rotation and defining an outlet passage communicating with said chamber, means on said nozzle body engaging with said valve cup for rotating said valve cup in response to rotation of said nozzle body, and an apertured wall of said nozzle body terminating said outlet passage, whereby said nozzle body may be swivelled and rotated to change the trajectory of water discharged through said wall, and on rotation, when the valve cup is at the first of said extreme positions flow is at a maximum, and when said valve cup is at the second of said extreme positions flow is restricted, while during rotation between said first and second extreme positions any substantial flow is prevented.

Claim 7

An ablutionary appliance comprising a water catchment member having an uncontrolled waste outlet so that water cannot be retained in said catchment member, a water delivery pipe having an outlet disposed above said catchment member, a bush through which said water delivery pipe is displaceable lengthwise for adjusting said outlet end to any one of a range of predetermined positions above said catchment member, an intermediate pipe having one end connected to said bush and within which said water delivery pipe may be displaced, a connection at the other end of said intermediate pipe for connection to a water supply pipe, a substantially spherical head mounted on said outlet end and having a through passage communicating with the interior of said water delivery pipe, a substantially cylindrical sleeve mounted on said head, a substantially cylindrical liner located and seated within said sleeve and said liner engaging with said head for swivelling movement of said liner and said sleeve relative to said head, an internal bore in said liner communicating with said through passage, a valve cup received within said liner for rotation relative to the axis of said liner between two extreme positions spaced 180* apart, first and second diametrically opposed ports of different cross-sectional areas formed in said valve cup, a chamber extending between said sleeve and said liner, said chamber having an entrance through a port formed in said liner arranged to register with one or other of said first and second extreme positions of rotation of said valve cup, a nozzle body mounted on said sleeve for relative rotation and defining an outlet passage communicating with said chamber, means on said nozzle body engaging with said valve cup for rotating said valve cup in response to rotation of said nozzle body, and an apertured wall of said nozzle body terminating said outlet passage, whereby said nozzle body may be swivelled and rotated to change the trajectory of water discharged through said wall, and on rotation, when the valve cup is at the first of said extreme positions flow is at a maximum, and when said valve cup is at the second of said extreme positions flow is restricted, while during rotation between said first and second extreme positions any substantial flow is prevented.
