My present invention relatesto improved .multiple combined-stack and individual waste and group venting assemblies. I

My present invention-.provide wmain stack-and sub-main stack piningfor the discharge, with group :venting, of groupsoi plumbingfixtures disposed on floor rlevels of a-building structure, each group comprising a plurality of plumbing @fixtures disposed on any given floor level,- the multiple groups being disposed on the respective (floor, levelsinisubstantiahvertical alignment;

My invention provides for the" locating of "the desired particular plumbing 'fixtureswon any given floor level ;in:any position mutually with respect to one anotheras'desired;lthedndividual plumbing fixtures :being d sposedoptionally at :any radial location, the '3 soil :pipe stack :and main vent stackserving ;as the center; Preferably, each plumbing fixture: isroonn'ected by individual waste branch with the waste and venting assembly of itsfloor level.

In preferred embodiments of my invention, each waste andventing assembly'rfor any given floor level comprises arfittingydispo'sedrat and "extending through the floor;level,';such -fitting c'omprising laterally extending :channel's; the-"termini of which --are:-disposed :above" the jflOOI slabj-and arranged to lee-connected withawastabranches of plumbing fittings on such floor level;

In the preferred embodiment indicated in Fig. 4, the main vent stack is denotedby the reference number 21, which excepting for the first floor, extends through the respective floor levels and is suitably connected at its upper terminus, as by a suitable fitting 28, with an uppermost portion of the soil pipe stack III. The lower ter-.,

minus 21a of the main vent stack 21 is suitably connected as by piping 29, to theupper terminus of the fitting ll of the waste and venting assembly of the first floor, and communicates through such fitting l1 and therewith through the fitting l6 and fitting 26 with the lower portion lllb of the soil pipe stack.

Referring to Figs. 2 and 3, and also Figs. 5 and 6, with respect to the waste and venting assemblies of the second and upper fioor levels, the upperterminus llc of the fitting I1 is connected bygagpipejtfl or eq ivalent to a fitting '3l to afford communication of the same with the main vent stack:2|,; Fig. '7 illustrates in central vertical section a typical formation of such fitting 3|. Fig. 8 illustrates in central vertical section a typical formation ofthe fitting l1. Fig. '8 illustrates also. the generalformation of the fitting I 6.

Preferably atjeach floor .level, the soil pipe stack, l 0 and main ventstack 2'! and the waste andiventing assemblyof'such floor level are enclosed in a suitable casing the walls of each casing advantageously extending from the floor slab to the ceiling; removable closures of suitable openings in suchcasingwalls are provided for afiording. access for'insp'ection and repair.

'At'the respective floor levels, the positions of thejgroup of plumbing fixtures typified by toilet bowl [8,; bath, tub. or'shower 20, lavatory 23, kitchen sink or laundry tub 25, may be varied asjdesired or required with respect to the soil pipe stack In as a center; Also, preferably, each plumbing fixtureisprovided with a waste branch individually corinectingsuch fixture with the waste and group venting assembly of its floor level, i. e independently of'any other plumbing fixture. creep venting of the plumbing fixtures at each floor level is thus afforded by its independent branch wasteconnection with its as- ,sociatedwaste andventing assembly through the main vent stack 21 in cooperation with the soil pipestack l ll,'t hereby insuring full flow of discharge of the plumbing fixtures singly or plurally at all timesat any given floor level and concurrently at any 'tw'ojor more floor levels. I In compliance with code regulations, suitable cleanoutinspecticn and'repair may be provided at any convenient location, such as at the flooring3 2 of the fiooring basement or equivalent, as is indicated at 33., v v The respective fittings serving as component parts of rnyi co'mbined stack and multiple waste and venting: assemblies preferably embody the construction of U; ,8. Patent No. 2,065,523, dated December 29, 1936, entitled Methods of uniting fiuidfs'tr'eams and devices therefor.

-Water. closets ofthe type set forth and claimed inrny USS-{Letters Patents'Nos. 2,066,881 and 2,066,882, both granted on January 5, 1937, and linfsubsedu'ently granted patents, are particularly applicable inconnection with the instant inventionjin that "the discharge of the same through the selected branch waste piping is disposed above the-floor level.

"fThe present invention affords also the assembly as a unit of the casing and therein enand thelike being disposed spaced from the Walls 7 of the building structure.

By the provision of the casing, all soil and vent stacks and all water distribution piping and therewith connected parts are concealed from view, while at the same time optimum access is afforded to such enclosed parts. Such arrangement simplifies the insulation of such'piping thermally and particularly for reduction of noises ensuing in the-flow of supply water and aqueous discharges.

Whereas I have describedmy invention by reference to specific forms thereof, it will be understoodthat many changes and modifications may be made without departing from the spirit of the invention.
