Abstract
Abstract A shower head includes a nozzle assembly and an axially movable surrounding adjustment shroud. The nozzle assembly per se is of the rotary stem type and functions to discharge a plurality of separate water streams in a desired rotating pattern. The trajectory of the several streams oscillates within defined limits. Each stream is composed of individual water droplets. The shroud is adjustable axially along the nozzle assembly so that the discharge characteristic of the head is variable, without affecting water flowrate, from a discharge comprised of these several streams to a relatively hard, closely focused water discharge in which the individual streams are merged, and also to a soft aerated closely focused discharge in which the several streams are merged.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
265 words
A shower head comprising 1. a nozzle assembly including a. a body adapted to be connected to a source of water, and b. a stem rotatably mounted substantially coaxially through one end of the body and defining orifice means for discharging a plurality of individual water streams; 2. a discharge adjusting member defining a central cavity having a. an outlet opening of diameter greater than the portion of the stem defining the orifice means, the outlet opening having a definite extent axially of the cavity, which extent is many times smaller than the diameter of the outlet opening, b. an elongate major diameter portion within which at least the one end of the nozzle assembly body is disposed, and c. a conical shoulder surface formed concave away from the outlet opening and extending from the inner end of the axial extent of the outlet opening to the adjacent end of the major diameter portion; and 3. means mounting the adjusting member around the nozzle assembly for movement coaxially relative to the nozzle assembly into and out of modulating engagement with the water streams by the surfaces of said cavity, the adjusting member being movable relative to the nozzle assembly between a first position in which the adjusting member outlet opening is disposed sufficiently proximate the one end of the body for passage of the streams from the orifice means without contact with the adjusting member, and a second position in which the streams engage the major diameter portion of the adjusting member cavity at a location spaced along the cavity from the conical shoulder surface.

Claim 3
Dependent Claim
107 words
a discharge adjusting member defining a central cavity having a. an outlet opening of diameter greater than the portion of the stem defining the orifice means, the outlet opening having a definite extent axially of the cavity, which extent is many times smaller than the diameter of the outlet opening, b. an elongate major diameter portion within which at least the one end of the nozzle assembly body is disposed, and c. a conical shoulder surface formed concave away from the outlet opening and extending from the inner end of the axial extent of the outlet opening to the adjacent end of the major diameter portion; and
Claim 4
Dependent Claim
107 words
a discharge adjusting member defining a central cavity having a. an outlet opening of diameter greater than the portion of the stem defining the orifice means, the outlet opening having a definite extent axially of the cavity, which extent is many times smaller than the diameter of the outlet opening, b. an elongate major diameter portion within which at least the one end of the nozzle assembly body is disposed, and c. a conical shoulder surface formed concave away from the outlet opening and extending from the inner end of the axial extent of the outlet opening to the adjacent end of the major diameter portion; and
Claim 5
Dependent Claim
25 words
A shower head according to claim 1 wherein said location is about half the distance from the orifice means to the adjusting member outlet opening.
Claim 6
Dependent Claim
109 words
means mounting the adjusting member around the nozzle assembly for movement coaxially relative to the nozzle assembly into and out of modulating engagement with the water streams by the surfaces of said cavity, the adjusting member being movable relative to the nozzle assembly between a first position in which the adjusting member outlet opening is disposed sufficiently proximate the one end of the body for passage of the streams from the orifice means without contact with the adjusting member, and a second position in which the streams engage the major diameter portion of the adjusting member cavity at a location spaced along the cavity from the conical shoulder surface.
Claim 7
Dependent Claim
109 words
means mounting the adjusting member around the nozzle assembly for movement coaxially relative to the nozzle assembly into and out of modulating engagement with the water streams by the surfaces of said cavity, the adjusting member being movable relative to the nozzle assembly between a first position in which the adjusting member outlet opening is disposed sufficiently proximate the one end of the body for passage of the streams from the orifice means without contact with the adjusting member, and a second position in which the streams engage the major diameter portion of the adjusting member cavity at a location spaced along the cavity from the conical shoulder surface.
Claim 8
Dependent Claim
