Abstract
Abstract My invention discloses a novel device for adding liquid soap to shower water. Liquid soap is drawn through a tube member by harnessing the negative pressure in a sleeve member, situated within a water source leading to a shower nozzel, relative to the atmosphere. Means for controlling the volume of soap flowing through a tube member adjusts the amount of soap going through the shower head.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
251 words
A device for adding soap to shower water comprising: a. a sleeve member open on one end, situated in a water source leading to a shower nozzle, said open end directed toward the shower nozzle; b. a depending tube member connected to the sleeve member; c. a liquid soap container attached to the tube member, one end of the tube member being situated preferrably below the level of liquid soap in the container; d. means for drawing soap through the depending tube member by harnessing the negative pressure, relative to the atmosphere, of the sleeve member when water is flowing through the water source; e. said means for drawing soap further comprising: a first control member situated on the depending tube member; a second control member situated within the first control member and having an aperture positioned within the depending tube member, said second control member being rotatable within the first control member to permit either the unobstructed or obstructed flow of soap through the depending tube member determined by the position of the aperture when rotated; a rope member attached to the second control members to assist a user in rotating the control member; a stop member situated on the water source placed above the rope member in a manner to permit the rotation of the control member so that unobstructed flow exists through the aperture and depending tube member when desired and; means for controlling the volume of soap flowing through the depending tube member and connected to it.
Claim 2
Independent Claim

A device for adding soap to shower water comprising: a. a sleeve member open on one end, situated in a water source leading to a shower nozzle, said open end directed toward the shower nozzle; b. a depending tube member connected to the sleeve member; c. a liquid soap container attached to the tube member, one end of the tube member being situated preferrably below the level of liquid soap in the container; d. means for drawing soap through the depending tube member by harnessing the negative pressure, relative to the atmosphere, of the sleeve member when water is flowing through the water source; e. said means for drawing soap further comprising: a first control member situated on the depending tube member; a second control member situated within the first control member and having an aperture positioned within the depending tube member, said second control member being rotatable within the first control member to permit either the unobstructed or obstructed flow of soap through the depending tube member determined by the position of the aperture when rotated; a rope member attached to the second control members to assist a user in rotating the control member; a stop member situated on the water source placed above the rope member in a manner to permit the rotation of the control member so that unobstructed flow exists through the aperture and depending tube member when desired and; means for controlling the volume of soap flowing through the depending tube member and connected to it.
Claim 3
Dependent Claim
61 words
The device of claim 1 wherein one of the depending tube member is dimensioned with threads and wherein the means for controlling comprises: a jacket member dimensioned to fit along the threads, having a void whose size can be adjusted by turning the jacket member along the threads to permit differing amounts of liquid to flow through the depending tube member.
