DRAINAGE AND VENT FITTING FOR PLUMBTNG SYSTEMS.

Application filed September 21, 1922.

To all 'whom i may concern.'

Be it known that l, JOHN L. FRUIN, a. citi- Zen ot the United States,v residing at Chicago, in the county ot Cook and State oi illinois, have invented certain new and useful improvements in Drainage and Vent Fittings for Plumbing Systems, of which the following is a specification.

This invention relates in part to an improved plumbing system designed to handle the discharge from a closet, bathtub, lavatory or sink in a multiple story building; and the main object of the invention is to provide special drainage and vent fittings at the top and intermediate floors ot such a character and structure as to permit the main soil and vent stack and the revent stack to lie in close juxtaposition and occupy but a minimum ot' space in a vertical wall of the building in which the system is installed.

Other objects. and attendant advantages ot the invention will be apparent to persons skilled in the art as the same becomes better understood by reference to the 'following detailed description, taken in connection with the accompanying drawing, in which- Fig. l is an elevation ot my improved plumbing system installed in a manner to receive the discharge from a closet or bathtub; l

Fig. 2 is a similar View of the same system, installed in a manner to accommodate the discharge from a lavatory or sink;

Fig. 3 is an elevation in a plane at right angles to that ot Figs. 1 and 2 of the to-pmost drainage and vent fitting;

Fig. i is a similar view ot the drainage and vent fitting used at intermediate floors; and

Fig. 5 is a cross-section on the line 5-5 of Fig. l.

Referring to the drawin g, 1 designates the lower floor, 2 an intermediate fioor, 3 a top floor, and t a roof of a multiple story building such as is adapted to be served by my improved plumbing system.

Referring first to Fig. 1, the main vertical soil and vent stack comprises an upper straight pipe section 5 extending thro-ugh the roof 4, the main stem 6 ot a drain and ventfitting located at the top fioor 3 and connected at its upper end into the pipe section 5, an intermediate straight pipe section 7 connected into the lower end ot thc main stem of the fitting 6, a main stem 8 of an in- Serial No. 589,603.

termediate drain and vent fittingv located at the intermediate floor and connected into the lower end of the pipe section 7 another straight pipe section 9 connected at its upper end to the lower end of the stem v8 ot the intermediate fitting, the arm l() of a lower fitting located at the first floor l, and the lower portion ot the main stem ll of' said lower fitting, this latter connecting into the house drain indicated at 1.2.v l The revent stack comprises an elbow branch 13 ot the top titting, a straight ver ticalpipe section 14,con'ununicating with the lower end of the elbow branch 13, acurvedor bent section 15 communicating with the lower end of the vertical straight section 14, and a lower straight section le con'in-innieating at its upper end with thevbent section 15 and at its lower end with the upper end of the main stem ll ofthe lowermost fitting.

The upper fitting is provided with a lateral drain branch 17 disposed below the junction o-il the members (3 and 13; the intermediate fitting has an arm 1S on which is a lateral drainage branca. 19, and the lower fitting is equipped with a lateral drainage branch located above the junction oi the main stem 11 and arm l0.

At the intermediate floor is a vertical branch 2l of the revent stack that entends fil'om the junction ot the sections 11i and l5 straight downwardly into the upper end of the fitting arm. 18 to provide a veut tor the drainage branch 19.

It will be observed that in the described construction the vertical soil and vent stack and the revent stack lie very close together and substantially contiguous, and that the reventing of all the fixtures below the top and neXt to the top floors is secured by including in the revent stack the laterally offset curved or bent section 15 at each intermediate floor by which the revent conduit is carried past the drainage branch 19 at each intermediate floor. I have herein shown but a single intermediate floor; but it will be understood that where there are several intermediate fioors, the structure and arrangement herein shown at the intermedr ate floor 2 will simply be repeated at all the other intermediate floors.

The compact system above described may, so tar as the general organization is concerned, be built up 'from suitable pipe sections and fittings as desired; but a considerllt) able economy in the number of parts required can be effected by employing the novel integral fittings shown at the top and intermediate floors; the stem 6, elbow vent branch 13, and drainage branch 17 of the upper iitting being made integral; and the main and branch drain elements 8, 18 and l19 and the main and branch vent elements 15 and 21 of the intermediate fitting being all made integral. By employing the integral iittings herein shown and described, the entire system can be assembled with the additionof ordinary straight pipe sections such as 5, 7, 9, 14 and 16.

With. the system installed in the relation to the floors shown in Fig. 1, the drainage branches 17, 19 and 20 are adapted to serve either a closet or bathtub. In Fig.V 2 I have illustrated the' arrangement of the system in relation to the floor levels that will be employed where the drainage branches 17, 19 and 20 'serve a lavatory or sink. The structural organization of the system shown in .Fig 2 is'identieal with that shown in Fig. 14.

l claim- 1. A onepiece intermediate drainage and ventV itting for plumbing systems, comprising a vertical limb adapted to term part of a waste and vent stack and having a straight upwardly inclined lateral arm, a second vertical limb parallel with said iii-stnamed limband vcontinuous at its lower end with said arm and having a Venting function, a lateral drainage branch on said arm and a third limb merged at its upper end into said second vertical limb and extending downwardly and inwardly beneath said arm, said third limb lying in the plane of said vertical limbs and adapted to form part of a revent stack.

2. A one-piece intermediate drainage and Vent fitting for plumbing systems, comprising' a vertical limb adapted to form part of a waste and vent stack and having a straight upwardly inclined lateral arm, a second vertical limb parallel with said first-nanied limb in close proximity thereto and merged at its lower end into the upper end of said arm and haring a venting function, a lateral drainage branch on said arm and a third limb disposed alongside, and iu thc plane, of said Vertical limbs, said third limb merged by an elbow bend at its upper end into said second vertical limb adjacent to the upper end ot the latter and at its lower end inclined downwardly and `inwardly be ncath said arm, said third limb adapted to -t'ormpart of a revent stack.

3. A one-piece top drainage and vent fitting for plumbing systems, comprising a Vertical limb adapted to `form part of a waste and vent stack, a depending elbow branch on the upper end of said vertical limb adapted to form the upper end of a re- Vent stack, and a lateral drainage branch on said vertical limb below the junction of the latter and said depending elbow branch, and extending in a vertical plane at an angle to the vertical plane of said elbow branch.
