tubs and the like, and the soil or waste and a main vent pipes of such systems.

The invention has for its primary object to provide a system and fittings which are simple and compact and by means of which traps for fixtures may be arranged entirely within the wall space whereby only the clean-out openings of the traps are visible instead of having the entire trap exposed as in the ordinary construction.

A further object of the invention is to provide an improved construction and arrangementof parts including the position of the traps for the individual fixtures whereby siphoning of the traps may be avoided.

A further object of the invention is "to provide an improved fitting for use in vertical plumbing systems for connecting the soil and main vent pipes in which the trap may be formed integral with the fitting,thus making it possible to cast the arts from one pattern, securing not only simplicity and compactness but at the same time economy in the first cost of installatio A further object of the invention is to provide an improved fitting capable of use in a plumbing system of the described character for forming lateral extensions on floors adjacent the upper part of the system.

To the attainment of these ends and the accomplishment of other new and useful objccts, as will appear, the invention consists in the features of novelty inthe construction, combinato'n and arrangement of the sevcral parts, all as more fully hereinafter described and shown in the accompanylng drawings. I

In the said drawings, Figure 1 is an elevation of the improved fitting, the same being shown partly in section in order to more fully disclose the details of construction. Fig. 2 is a view taken in vertical section .trap being shown adjacent the through a building illustrating the system in position in the wall and floors. In this view three forms of the fitting are shown a one form like that illustrated in Fig. 1, a

fitting embodying a form of drum trap adjacent the bottom of the system, and a lateral extension fitting at the top embodying both aform of drum trap and the ordinary P-trap. Fig. 3 is a side view of the construction shown in Fig. 2 with the fixture connections removed. Fig. 4 is a view partly .in section of a modified form of the fitting.

adapted for use at the bottom of the vertical system for forming a connection between the soil and main vent pipes and a fixture. This fixture is shown provided with the improved form of drum trap. Fig. 5 is an illustrative view of a plumbing system provided with soil and main vent ipes, the

xture according to the common practice, and the View illustrates the manner in which siphoning may take place even though the'main vent pipe and its connection with the soil pipe is provided.

In the illustrations the commonv form of soil or. waste pipe 10 is shown, being connected at the bottom with the sewer pipe 11 and passing out through the top of the building through the ceiling 12 of the uppermost room and the roof 13 of the building. Horizontal divisions in the building forming floors and ceilings are indicated at 14 and I 15., while the vertical portions of the system itself are shown'entirely inclosed within vertical wall or partition 16.

17 is the usual form of main vent pipe standing approximately parallel with the soil pipe 10, oth the soil pipe and the main vent pipe being entirely contained within the walls of the vertical partition 16..

The improved fitting 18, forming a part of the present invention, is provided with a pipe section 18 adapted to form a portion of the soil pipe 10 with which it is connected by suitable joints 18 adapted to be either screw-threaded or lcad-calked. The fitting manner. However, the preferred form of forming this connection is to construct the fitting as shown in Fig. '1 and elsewhere,

providing the upper extremity with an inte Heretofore it has been the practice to install vertical plumbing systemssimilar' to.

the view shown in Fig. 5 in which 19 indicates a soil pipe, 20 the main vent pipe, and 21 the fitting forming a connection therebetween. The pipe leading from the fixture is then tapped into the connection 21 near the joining of the same with the soil pipe or it may be tapped into the soil" pipe itself adj acent to the lower end of the fitting connection, as shown in Fig. 5, thefixture pipe being indicated by the reference character 22, 23 being the bowl of thefixture. The usual form of P-trap 24 is shown in the-fixture connection 22, the same being at the upper end thereof adjacent the fixture. In this mode of constructing the trap it is found that there is constant danger of siphoning, particularly when it is found necessary to extend the pipe leading from the fixture some distance, as illustrated in Fig. 5. The main vent pipe and the connection 21 afford a preventive against siphoning from the action of the contents of the pipe after it enters the soil pipe but doesv not prevent the siphoning of the trap due to the action of the liquid in passing through connecting pipe 22 between the trap and the soil pipe. In .order to entirely obviate this objectlon in the invention the trap is formed integral with the fitting 18 and may be of any common form of construction, as a P-trap or a drum trap. In the fitting 18, illustrated in Fig. 1,'the pipe or branch vent connecting the soil and main vent pipes-is indicated by 18 and is provided with a branch 18 extending downwardly and then upwardly as in the common construction of P-traps. It will be seen by this construction that the entire fitting 18, including the trap, lies in the plane of the soil and main vent pipes, thus enabling the trap 'to'be hidden away within the walls of the partition together with the other portions of the ver; tical plumbing system, presenting a more sightly appearance than with the trap completely exposed to view.

At the extremity of the upwardly extend- I ing branch of trap 18 provision is made for connecting the pipe from the fixture, which preferably consistsin the angular portion 18 extending approximately at a right angle to the plane of the soil and main vent pipes and terminating at a pointadapted to reach just through the partition wall, there 6 being suitable meansprovided, as at 18*,

esaeea for a screw-threaded or lead-calked joint. A. suitable clean-out, as at 18 is provided at the bottom of the trap and preferably consists of a protuberance extending from the plane of the fitting outwardly in order also to reach just flush with the outer surface of the partition wall in order that it may be accessible without disturbing the wall.

A modification of,tl1e fitting just described is shown at 25, forming a connection or branch vent for the base of the main of the partition wall. It will be noted that the construction of this trap, which is shown in detail in'Fig. 4, is of the common drum type, the clean-out therefor being near the top of it as at 25 likewise extending laterally to. protrude through the partition wall.

Another modification of'the invention is illustrated by the fitting 28. This fitting is suitable for use on an upper floor of the system where there are no fixtures to be tapped into the soil or wastepipe above'this one, thus allowing the fitting of this character to be used, in which it is not necessary that the fitting shall communicate with the main vent pipe, the waste or soil pipe serving 'that purpose as there is no discharge into the system above. In the fitting 28 it will be noted that it is provided with a portion adapted to form a section of the soil or waste pipe and has the branch 28*, preferably cast integrally therewith, extending, as in the case of the other fittings, within the plane of the soil and main vent pipes and being provided with the same form of P-trap 28 as illustrated in fitting 18, being also provided with the usual clean-outlS and both a P-trap and drum trap are combined. The fitting is designated by the reference character 29 and is adapted to receive the waste from basin 30, through pipe 30, and bath 31, the P-trap 29* taking the pipe from 30 and the'drum trap 29- receiving the pipe 31 from the bath, the same entering the trap beneaththe floor 14. It will be seen that the traps comprising this fitting are of the forms illustrated in fittings 18 and 25, the usual'clean-outs l8 and being provided. The fitting is provided with the laterally extending vent pipe 29*, which may be tapped into the fitting 28 of the soil pipe, as shown, and the waste from. the fitting is carried to the soil pipe 10 by the laterally extending branch 29 beneath the floor 14. Additional venting means, as the pipe or extension 32, may be tapped into the fitting preferably into the vent pipe 29 as illustrated in Fig. 3.

In order that the invention might be fully understood, the details of the foregoing embodiment thereof have been thus specifically .but."
