Abstract
Abstract Substantially coaxial conduits provide a jet of water from the outer conduit along with relatively large bubbles from the inner conduit. The emission end of the inner conduit terminates upstream the emission end of the outer conduit, and there is a restriction in the outer conduit upstream the end of the emission inner conduit.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
92 words
A whirlpool bath attachment comprising a pair of substantially coaxial conduits adapted to be mounted on a bath tub with the upper end above water level and means for connecting the outer conduit to a source of water, the upper end of the inner conduit being open to the surrounding atmosphere and the lower end of said inner conduit terminating a predetermined distance within the corresponding end of the outer conduit, the cross-sectional area of the water passage at its narrowest point is less than the cross-sectional area of the inner conduit.
Claim 2
Dependent Claim
92 words
A whirlpool bath attachment comprising a pair of substantially coaxial conduits adapted to be mounted on a bath tub with the upper end above water level and means for connecting the outer conduit to a source of water, the upper end of the inner conduit being open to the surrounding atmosphere and the lower end of said inner conduit terminating a predetermined distance within the corresponding end of the outer conduit, the cross-sectional area of the water passage at its narrowest point is less than the cross-sectional area of the inner conduit.
Claim 3
Dependent Claim
15 words
A whirlpool bath attachment as defined in claim 1, wherein said inner conduit is flexible.
Claim 4
Dependent Claim
48 words
A whirlpool bath attachment as defined in claim 1, including a sleeve forming a fluid-tight connection with the upper end of said outer conduit, said sleeve having an aperture therein, and the upper end of said inner conduit forming a fluid-tight connection with the perimeter of said aperture.
Claim 5
Dependent Claim
32 words
A whirlpool bath attachment as defined in claim 1, wherein there is a restriction in the cross-sectional area of the outer conduit at a position upstream the end of said inner conduit.
Claim 6
Dependent Claim
39 words
A whirlpool bath attachment as defined in claim 4, wherein said restriction is created by an internal sleeve member projecting from a position within said outer conduit and downstream to a position upstream the end of said inner conduit.
Claim 7
Dependent Claim
37 words
A whirlpool bath attachment as defined in claim 5, wherein the aperture created by said sleeve member and the outer surface of said inner conduit has a cross-sectional area of approximately one-half that of said inner conduit.
