Abstract

Abstract A unitary plumbing fitting for connecting a pair of bathrooms disposed symmetrically on opposite sides of a partition to soil and vent stacks comprises a body having a vertical passage connectable at its lower end with the soil stack and at its upper end with the soil or vent stack, a pair of horizontally diverging branches projecting radially outwardly and inclined upwardly from the body with their terminals extending horizontally away from each other for connecting to a pair of water closets on opposite sides of the partition, a horizontally diverging Y-connection between and merging with the diverging branches and body at their intersection and being initially similarly upwardly inclined from said body with the outer end of its stem and its arms substantially horizontal at a lower level than the terminals of the diverging branches for connection to a pair of bathtub drains on opposite sides of the partition, a vertical branch on the outer horizontal portion of the Y-connection stem connectable to a vent stack passing between the arms of the Y-connection, and an additional branch projecting from the body in a diametrically opposite direction from the Y-connection, at the same level and similarly upwardly inclined for connection to a pair of wash basin drains on opposite sides of the partition and to the vent stack.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 105 words
A plumbing fitting comprising a body defining a vertical passage, a pair of horizontally diverging branches connected in side-by-side relation to each other and to said body and inclined upwardly therefrom, and a horizontally diverging Y-connection having its stem intersecting said branches and said body at the intersection of said branches with each other, said Y-connection being inclined upwardly from its intersection with said diverging branches and said body, and a vertical branch intersecting the stem of the Y-connection remote from the intersection of the same with said diverging branches, said vertical branch forming a single vent connection for both said Y-connections and said branches.
Claim 2
Dependent Claim 105 words
A plumbing fitting comprising a body defining a vertical passage, a pair of horizontally diverging branches connected in side-by-side relation to each other and to said body and inclined upwardly therefrom, and a horizontally diverging Y-connection having its stem intersecting said branches and said body at the intersection of said branches with each other, said Y-connection being inclined upwardly from its intersection with said diverging branches and said body, and a vertical branch intersecting the stem of the Y-connection remote from the intersection of the same with said diverging branches, said vertical branch forming a single vent connection for both said Y-connections and said branches.
Claim 3
Dependent Claim 37 words
A plumbing fitting according to claim 1 wherein the axes of the stem of said Y-connection and of said diverging branches lie in a common inclined plane adjacent their intersection with each other and with said body.
Claim 4
Dependent Claim 30 words
A plumbing fitting according to claim 1 wherein said diverging branches extend generally radially from said body for equal distances and thereafter are parallel to each other a substantial distance.
Claim 5
Dependent Claim 30 words
A plumbing fitting according to claim 3 wherein the extremities of said main branches are bent away from each other at 90* to the parallel portions of said main branches.
Claim 6
Dependent Claim 23 words
A plumbing fitting according to claim 4 wherein the axes of said main branches lie in a common inclined plane throughout their lengths.
Claim 7
Dependent Claim 38 words
A plumbing fitting according to claim 5 wherein the axes of said stem of said Y-connection and of said main branches lie in parallel vertical planes except at the inner and outer end portions of said main branches.
Claim 8
Dependent Claim 43 words
A plumbing fitting according to claim 6 wherein the axes of the radially outer portion of said Y-connection stem and the arms of said Y-connection lie in a common horizontal plane, said vertical branch communicating with said outer portion of said Y-connection stem.
Claim 9
Dependent Claim 30 words
A plumbing fitting according to claim 7 including an additional branch intersecting said body at substantially the same level as said diverging branches and angularly displaced from said main branches.
Claim 10
Dependent Claim 33 words
A plumbing fitting according to claim 8 wherein the axes of said additional branch and of said Y-connection stem lie in a common vertical plane and intersect said body on opposite sides thereof.
Claim 11
Dependent Claim 22 words
A plumbing fitting according to claim 9 wherein the axes of said main branches and said additional branch are of similar inclination.
Claim 12
Dependent Claim 33 words
A plumbing fitting according to claim 10 wherein the axes of said main branches, said Y-connection stem and said additional branch intersect at a common point on the vertical axis of said body.
Claim 13
Dependent Claim 89 words
A plumbing fitting according to claim 6 wherein said body is arranged for connection to a soil stack, the terminals of said main branches are arranged for connection to a pair of water closets, said Y-connection arms are arranged for connection to a pair of bathtubs, and said additional branch is arranged for connection to a pair of wash basins and to a vertical vent stack embraced by the arms of the Y-connection, said vertical branch of said Y-connection stem being arranged for connection to the same vent stack.
