Plumbing apparatus

Claim 2

A plumbing tree for a factory-built modular building having frame means supporting a floor with only limited vertical space available under the floor within the frame means, said plumbing tree comprising a. connector means having first and second conduits in substantial axial alignment and each lying in a plane pitched only slightly relative to a reference plane which corresponds to horizontal, and third and fourth conduits projecting laterally and oppositely from said first and second conduits substantially in the plane thereof, said second conduit having at least two inlets, and said second, third and fourth conduits communicating into said first conduit, b. sewer drain line means connected to said first conduit, c. first and second tub drain line means connected respectively to said two inlets of said second conduit and projecting oppositely substantially parallel to said first and second conduits, said first tub drain line being pitched substantially the same as said second conduit, and said second tub drain being pitched oppositely relative to said first tub drain, so that both of said tub drains provide flow into said second conduit and yet remain within the confines of said limited vertical space, d. first and second commode drain line means connected respectively to said third and fourth conduits and projecting laterally and oppositely from said first and second conduits, e. said conduits and said line means having a generally planar configuration to fit within the confines of the said space within said frame means.

Claim 3

The plumbing tree as claimed in claim 1 in which one of said tub drain line means crosses one of said third and foUrth conduits or the commode drain line means connected thereto.

Claim 4

The plumbing tree as claimed in claim 1 in which said second conduit also has a vent opening facing at slightly less than a right angle to the plane of said first and second conduits.

Claim 5

In a module of a building having frame means supporting a floor with only limited vertical space under the floor within the frame means, a plumbing tree mounted within the vertical confines of said space under a wall and serving to drain two bathrooms on opposite sides of said wall having two commodes generally opposite each other on opposite sides of said wall and two tubs spaced from each other on opposite sides of said commodes, said plumbing tree comprising a. connector means having first and second arms in substantial axial alignment and third and fourth arms projecting in generally opposite directions from said first and second arms, said first and second arms each lying in a plane pitched only slightly relative to the horizontal plane, and said third and fourth arms lying in the horizontal plane, b. a pair of inlets leading into said second arm, c. first and second drain lines leading from said tubs respectively to said two inlets of said second arm, said first tub drain line being generally axially aligned with and pitched substantially the same as said second arm, and said second tub drain line being pitched oppositely relative to said first tub drain line but only slightly pitched relative to horizontal, so that both of said tub drain lines provide flow into said second arm and yet remain within the confines of said vertical space below said floor, d. first and second commode drain lines connected respectively to said third and fourth arms and projecting laterally and oppositely in a horizontal plane from said first and second arms, e. a sewer drain line connected to said first arm and pitched substantially the same as said first arm in axial alignment therewith, f. said arms and said lines having a generally planar configuration and lying entirely within the confines of said space under said floor within said frame means so that said module can be transported without interference of the plumbing tree with the transporting means.

Claim 6

In a module of a building having frame means supporting a floor with only limited vertical space under the floor within the frame means, a plumbing tree mounted within the vertical confines of said space under a wall and serving to drain two bathrooms on opposite sides of said wall having two commodes generally opposite each other on opposite sides of said wall and two tubs spaced from each other on opposite sides of said commodes, said plumbing tree comprising a. connector means having first and second arms in substantial axial alignment and third and fourth arms projecting in generally opposite directions from said first and second arms, said first and second arms each lying in a plane pitched only slightly relative to the horizontal plane, and said third and fourth arms lying in the horizontal plane, b. a pair of inlets leading into said second arm, c. first and second drain lines leading from said tubs respectively to said two inlets of said second arm, said first tub drain line being generally axially aligned with and pitched substantially the same as said second arm, and said second tub drain line being pitched oppositely relative to said first tub drain line but only slightly pitched relative to horizontal, so that both of said tub drain lines provide flow into said second arm and yet remain within the confines of said vertical space below said floor, d. first and second commode drain lines connected respectively to said third and fourth arms and projecting laterally and oppositely in a horizontal plane from said first and second arms, e. a sewer drain line connected to said first arm and pitched substantially the same as said first arm in axial alignment therewith, f. said arms and said lines having a generally planar configuration and lying entirely within the confines of said space under said floor within said frame means so that said module can be transported without interference of the plumbing tree with the transporting means.

Claim 7

The plumbing tree as claimed in claim 4 in which said second arm has a vent leading upward through the floor of the module, and said bathrooms have sinks above floor level with drains leading into said vent.

Claim 8

The plumbing tree as claimed in claim 5 in which the pitch of said second tub drain line causes said second tub drain line to cross over the top of said third arm.

Claim 9

The plumbing tree as claimed in claim 4 in which said inlets are on opposite sides of said second arm in horizontal alignment and said third and fourth arms are on opposite sides of said second arm in horizontal alignment.
