t0 provide 45 kwater supply pipes H andi?, and the branch'i',
lxturesefof-the-lavatory -and-'withi--the lavatory connected by the pipe I with the flush tank. The drain passage 4 has an upwardly extending branch I6 closed by a deck plate I1, having two depressions I8 for an unscrewing tool. This branch is to give access to the drain passage fOr unstopping it when clogged.
It is obvious from the above detailed description that I have provided a manifold forming a focal point to whichlcome the hot 'and' cold water supply to theba'throom, from which ypoint -it is distributed to the several fixtures, and to which point the drainage from the supplied fixtures 1 flare provided wtih elevated faces or tables 32 and turns. excepting of course, the discharge f i ow from the flush tank.
The plumbing manifold I may befanaintegral.i

ment of the invention it is a fabricatedstructure made up of one or more sections I9, containing the parallel longitudinal tubular passages, integrated ywith intermediate .and/oi` end.- sections containing the T and. elbow diversions. Since the sections I9 are ofuniform.cross'fsectiomgthey maybe extruded instock length .unitswhich` are cut-to thesize required for the parfticularrnanifold being made up. The elbowfand 'lfsections are cast.
The intermediatesectionhas flat videntical end faces 2I, one ofwhieh Vis shown in FigureS.
This-section .includes -intermediate .parts vof vthe i passages 2, 3 and 4. The fiat faceslfarevsurroundedby shallow peripheral filanges 22, which are beveled .on .theinside as indicated atr23-in Figure 3, and the extruded :sectionsI-Sl` after hav.-
A'ing been cutfrom a stock length are correspondingly beveled at the end as at 24 infFigure5, :with caille or -other tool, tov fit -within the flange' 22 against the beveled side thereof.

iin Vconnecting the intermediate section; 2l) -to theextruded-section I9, the thin walled'thimbles '25 are employed, which iii snugly the respective passagesfeachhaving a feather-edged circumiferential collar 26fabout'its'rniddle. A thingesket 2IV of-so1der is used, having a `hole lpattern.corresponding to the passage .-arrangement inthe sections-to be joined. This gasketis placed within the recessfbounded by the Vflange 220i thefintermediate section. .Then the thimbles are pushed vthrough the holes in the gasket and ..into the .portions of the passages 2, -3 and4 in 'theinterg -mediate section. Then -the extruded sectionris pushed over the projecting parts of the ,.thimbles.
The `joint is subjected to endwise pressure'while a blowtorch. or other heatingmeansis applied. As the solder melts itis forced through the entire interface between the sections, including [the juncture formed by the bailles 23 and 24,making a vthorough sweated joint between said sections. The thimbles keep the solder from leaking into the passages which the joint intersects.
Whenas in Figure 1, the section 20`is between two extruded sections, the details of the -joint on each side of the intermediate section are iden# tical. The vsamev procedure isfollowed with respect .to=an.end section,such as the section 28,which is shown in Figures 1, 2, 6 and 7. The end-section is provided with a flat end face 29, bounded by the peripheral tapered flange30-g the extruded Ysection I9 iscorrespondingly chamfered -at vthe adjacent end; the twosectionsare juxtaposed -.with thimbles 25fconnecting the'alignedparts of the passages, anda gasket 2'Iof solder placed in Lfifthemanlfold is not of corrosion resisting material. The. deck plate I1 is flush with the tile.
