"solim (class-2,10 i v when said fitting is placed in waste stackitthe I Generically this'yinvention relatesto a' fitting used inplumbing systems and especially ingconnection with bath tubs, water closets, wash of a siriglecasting forplumbing stack fitting known to the} trade as a gang fitting and is a combined closet and bath waste and vent fitting minimum of space andto save labor in installation. j

Animportant object of this invention is the provision of a plumbing stack fitting made in a single form knownasaT and also in adouble, form known'asa cross or code-cross adapted to eliminate extra vents with a comparatively small, openingfor bathtubconnections,"and below, a

large opening for closet bowl outlet, and so posilarge lower opening pointing directly tofcloset bowl outlet, the upper smaller bath opening is automatically on a direct linewithbath* tub waste'fthereby eliminating extra ventsfcalking joints and bends :heretofore required, andwalso designed to save time and labor'in installation to conceal the plumbing pipes, etc.

j In :Fig. 1 there is, showna washbasin bowl 2, bath tub- 3, and stack waste line 4.

in connection: with the furring of ceiling in order I The portion of'thejstack or main soil line as shown in Fig. 1 comprises sections (floodecross Section I, and section8. Section-6 is*posi5 tioned asto eliminate calked joints and bendsheretoforeirequired in waste fittings. e i One of the principal objects of this invention isthe provisionof a plumbing fitting comprising waste passage, lower large closet waste passage extending at right angles'from said m ainpassag e and upper smallersimilarly extending bathwaste an integral casting formed with a main soil' or passage communicating with said mainfpassage,

the upper part of said main passageacting asa vent to preventsiphonage of bath traps, thereby eliminating extra vents, the relative positions of said upper and lower passages being such that when the fittingis operatively positioned in the wardly from diametrically oppositesides of pormain soil or stack line, calkedjoints, bends and extrafconnections are eliminated. i

With these and other objects in viewi 'which \villbecome apparent as the description proceeds,"

theinvention resides in the construction; conibination and arrangement of parts hereinafter morefully described and claimed, andillustrated in the accompanying drawing, in which like cha'r acters of reference indicate like parts. throughout the several figures, of which:

,, Fig, l is a similar view showing the arrange} ment with my improved T or code-cross fitting. Fig. 2 is an elevation of my improved fitting.

after m rire fully appear.

the lower end of section 5 as will be well understood i i i My improved code-cross section 1 comprises "a vertically extending pipe or mainbodly portion l6 terminating at its upper end in the elongated hubahd flange portions [1 and I8, respectively,

and at its lower end in flange 19. Spaced above its lower end section 1 is formedwithbranches 20 extending substantially at right angles outtion 16 and terminating in the enlarged hub and fiange,'sections 2| and 22, respectively, aridcon stituting the closet openings 22 as willhherein Above the branches 20 in substantial vertical alignment therewith and extending irompipe l6 are thediametrically opposite branches 23formed with the right angularly extending portions '24 terminating in the-enlarged hub portions 25 projecting at right anglesto hub portions Hand constituting bath openings 25" of smaller diameterthan' openings 22. IThe'branches from the right angular extendingportions 2.4 adjacent hubs} .25 expand downwardly to} section W at points immediately above A branches ;20 forn1ing the inwardly and, downwardly inclined walls Z6.

This construction provides large ppienings at points (of intersection withthe main body por tion It and terminates in the comparatively small openings 25' located above thelarg'e closet openings 22' and connected to section IBso that'the upper part of said section acts as'a ventand pi vents the bathjtrapfZ'I from siphoning; swni directly more fully appear. Code-crosssection 1 I; closet i mounted under floor 9 with hub portion H extending above the floor and adapted to receive the lower end of section 6 as clearly shown in Fig/. the lower end extending through the ceiling 28 sembly, as shown in Fig. 1, located on the op posite side of a partition Wall not shown. The

trap 21 is suitably connected to the outlet of bath 1 3, and, by a suitable pipe 3| to inlet opening 25"; the free end of which is adapted to be received ing in time and labor incident to installation, and

.desire, protected by Letters Patent is as set forth by hub and efiects communication with said bath opening 25' as will be clear without further discussion. In this connection it will bevnoted that branches 2!) and 23 are connected by the ver tical web 32 which unites them into a unitary structure. l a

eglltfw ll be noted that where only one-bath in stallation is' necessary, branches 2!! and 23 on one sideof thecode-cross 1 may be plugged, therebytconstituting in effect a single or T -fitting, or a elj' casting formed with said branches on one side 11, fitting is compact, and Fig. 1' shows how the closet and bath can be connected to the. single stack, waste and vent line 4 within the space between 10'? joists, that being the distance between floor} and ceiling 28, and constituting a sanitary installation,-,and eliminating the vent or vents and the necessity of furring the ceiling below, as requiredin connection with the prevailing con struotions. r a

.,.' .;It,Wil1 be apparent that I have constructed a plumbing fitting adapted to occupy a minimum of space and which, is a combined closet, bath waste, and vent fitting comprising an integral casting,

thelsmalhbath openings being placed above th e largecloset openings and connected to the main body section I6 so that the upper part of, said section acts as a vent and prevents siphonageof bathtrapsor traps. Such constructionnot only afiords the advantages above noted but also eliminates additional vent piping, heretofore in use, as well as separate vents forthe bath traps.

the relation of the closet. and bath openin gs, and their location are such that when the Tor code-cross fitting is operatively positioned the" stack or main soil line with the lower large ol inings'pointing directly to, the closet bowl outletthe upper small opening is automaticall positioned in a direct line for connection with the bath waste outlet, thereby eliminatingthe calked joints and bends heretofore required.

i From the above it will be apparent that by the use of my improved fitting the vent heretofore prevalent is eliminated as Well as the added ex pense for vents for the respective-bath traps, and by my construction the portion of the main body onstem disposed above the bath branches acts as a ventto prevent siphonage of the bath trap, and the relative positions and arrangement of the bath and closet branch outlets is such that when thefitting is operatively positioned in the soil line,for instance, with the large closet inlet opening facing the closet outlet, the bath inlet will be in a direct line with the bath trap outlet, there'- by "eliminating the prevailing calked joints and bends, and in addition I have provided an integral fitting, simple in construction, manufacturable 'or expense, adaptedto effect a savthe bath branch acting therewith as a vent to.

may be installed, and in either case the eflicient for the purposes intended.

Although in' practice it has been found that the form of the invention illustrated in the accompanying drawing and referred to in the above description as the preferred embodiment is the most efficient and practical; yet realizing the conditions concurrent with the adoption of the invention will necessarily vary, I desire to empha sizethatvarious minor changes in details of construction, proportion and arrangement of parts, may be resorted to withinthe scope of the appended claims without departing from or sacrificing any of the principles of this invention.

Having. thus, described my invention; what I in the following claims:
