Application filed February 23, 1921. T all whom t may concern. Be it known that I, FREDERICK ANTON IVARREN, a citizen of the United Sta-tes, residing at Atlanta, in the county of Fulton and State of Georgia, have inventednew and useful Improvements in Plun'ibing Installations, of which the following is a specification. This invention generically relates to plumbing installations, more specifically, it is directed to an improved connection designed to function as a water-seal-trap for lavatories and similar fixtures. The fundamental purpose of this invention is to effect a simple inexpensive plu nibing assembly which will expedite and inaterially decrease the cost of maintenance and installation. Another object of this invention is tor provide a plumbing installation for lavatories and the like, which conceals the trap from View and eliminates unsightly parts ordinarily located beneath the fixture. IVith these and other objects in View, this invention consists in certain novel details of construction, combination and arangement of parts to be more specifically' hereinafter set forth and claimed. n Briefly stated this invention consists essentially of two major components, one being concealed in the wall, the other exposed beneath lthe fixture. The concealed element embodies a malleable casting externally threaded at its inner extremity, bent intermediate its ends to form a water-seal-trap, and iianged at its outer extremity for attachment to a soil or drain pipe; the exposed element consists of a piping or system of pipings establishing a connection between` the fixture and the free end of the concealed element. In the accompanying drawings, Figure l is a side elevation of the complete assembly, illustrating the latter as applied to a lavatory; Figure 2 is a fragmentary elevation, illustrating the concealed element fixed to a soil or drain pipe; Figure 3 is a fragmentary side'elevation illustrating the application of this improved trap to a three-piece lavatory set; Figure 4L is a fragmentary side eleva-tion of the connection shown in Figure 7 with the fixtures removed; and Figure 5 is a fragmentary sectionized perspective illust-rating' the concealed ar- Serial No. 447,254. rangement of the trap for a bath tnb'connection. To facilitate the discussion of this invention, the exposed and concealed elements will hereafter be designated, fixture connection andl trap. Heretofore when making a trap connection between the fixture and the soil or drain pipe, it has been necessary for the operator to unite the several components of the assembly with what is known in Vthe trade as lead joint Wipings. This requires al great deal 0f time, experience and materially increases the cost of installation. lt is yalso necessary to bend a lead stub (which extends from the soil pipe to the trap) at an angle of approximately 90, which decreases the thickness of its Wall, in the vicinity of the bend, and weakens the pipe so that it is readily susceptible to damage. It is, therefore, the aim and purpose of this invention to provide an assembly Which dispenses with the lead stub, likewise with the joint wipngs, and permits rapid installatimi with a minimum expenditure of time, labor and material. In the illustrated embodiment characterizing this invention, reference being had especially to Figure l, a ,lavatory installation is shown consisting of a malleable cast iron pipe, gradually increasing in diameter from its inner to its outer en'd. This pipe, is located in the Wall or between the floors of a dwelling and constitutes the waterseal-trap 1. It is formed by bending the pipe upwardly from its inner end as at 2, and laterally from the bent portion as at 3, producing a trap chamber 4 having a liquid level indicated at 5. The inner end of trap 1 is externally threaded as at 6 to accommodate a ferrule or similar union. The outer end of the trap is formed with a peripheral iiange 7, coinciding with the like flange of the soil pipe 8 to which it is caulked; The threaded or inner end 6 of the trap is connected by a ferrule 9 to the inner end of a connection 10 located beneath the tixture, which in the present instance is bent at an angle of approximately The upper or free end of this connection is joined by a ferrule 11 to the tail piece 12 of lavatory fixture 13. From the foregoing structural outline, it isevident the installation proposed by this invention dispenses with the lead stub ordi- Y this type (that is'to say, the lead pipe ex Vtending from the soil pipe to the trap) eliminates joint wiping and presents a trap having a wall of uniform thickness not readily damagedwhen subjected to undue stress, and places the Water-seal of the trap adjacent to the vent-line, thus affording. better :ventilation than would otherwise prevail. Aside from the features noted sV also manifest this invention by virtue of its simplicity will expedite installation and effect a marked saving in time, labor and inaterial. y l In thediscussion of this invention two extremely simple lavatory fixtures havebeen referred to.` It is to be understood, however,- this improved trap is applicable to thel more complex multiple arrangements, including lavatory, toilet and bath,V .the connections essential l to assemblies of thisl character being shown in `Figures 3, .Land -5 invvhich event the savingl in material, Vtiineand laborl is greatly increased owing to the severa-lv parts eliminated and the many joint wipings dispensed with. Although 'in the foregoing, certain ele4 ments may have been set forth as best adapt-l ed to perform the functions allotted to them, nevertheless, it is to be understoodtthat variv ous minor changes as to form, subst-ance, etc., ' vention. Having. thus described my invention, and without enumerating variations vand equivalents, what-l desire protected by Letters 'Patc ent is as set forthin the following claims: In a plumbing installation, atrap member consisting of a one-piecemalleable castingV pi-p'e flanged at one end fori attachment to a soil'pipela-rid threaded at its opposite end for .attachment to a fixture connection 'the bore of said pipev gradually increasing indiaineter from its threaded .end to its flanged end and said pipe being bentintern'iediate its ends toprovide a vertically disposed trapV portion from Vwhich the opposite ends Vof the pipe extend horizontallyin relatively right angular relation and in vertically spaced horizontal planes Yso that the outer or flanged portion ofthe pipe is above Vthe linner "or threaded end of the pipe for effecting a trap'and for positioning -the .ci-own of .the trap nearer Vto the soil pipe.
