Patented Nov. 17, 1942 UNITED STATE PLUMBING FITTING l Mitchell s. Little, Hartford, Conn., assignorrto L The M. S. Little ,Manufacturing Company, Hartford, Conn., a corporation of Connecticut Application November 4, 1941, Serial ,No. 417,759
1 Claim.
This invention relates to those plumbing ttings which are designed to connect a plurality of waste outlets, such as the outlets of double compartment sinks or wash bowls, or a sink or bowl and a laundry tub, to a single drain conductor, which ttings are so designed as to provide a liquid seal that will not only prevent the escape of sewer gas from the drain through the tting but also obstruct the passage of obnoxious odors from one waste outlet to the other.
The object of the invention is to produce a fitting of the character mentioned which will not only conform to the standard sanitary regulations and local ordinances but will also meet the demand for easily made tight and lasting joints between the waste outlets and drain conductor. It-practically never happens that the centers of two waste outlets are located at exactly the same height above, or at precisely the specified distance from the center of the drain conductor, which conditions render easily made and tight junction of a plurality of joints arduous.- To meet the conditions and overcome the diiculties mentioned the tting which is the subject of this invention is formed of two sections, a trap section adapted to be secured to the drain conductor and a waste section adapted to be connected with two waste outlets, these sections being secured together below the water line of the trap by a durable yielding metallic joint that not only allows turning but also tipping of the sections with relation to each other, and which when positioned can easily be made Very tight,
Fig. l of the accompanying drawing illustrates one design of the fitting and the way it may be connected to waste outlets.
Fig. 2 shows another design of the fitting.
Fig. 3 is a section of the fitting shown in Fig. 1 on larger scale.
Fig. 4 is, on still larger scale, a detail section showing the joint between the two sections of the tting.
The fitting is comprised of a lower or trap section I and an upper or waste section 2. The trap section 4contains the trap chamber 3 and its discharge end 4 is adapted to be connected to a drain conductor. The waste section has two branches 5, 6 which may extend at substantially right angles to each other, as shown in Fig. 1, or in substantially horizontal alignment with each other, as seen in Fig. 2, the ends 1, 8 of the branches being adapted to be respectively connected to waste outlets 9, I0. In the interior the waste section has a wall II which extends and separates the passages from the intakes of the branches.
The two sections, waste and trap, of the fitting are joined below the water level of the trap. In the form illustrated and end of a sleeve I2 of relatively thin metal is inserted into and tightly connected with the intake end of the trap section. The other end of this sleeve has an outwardly spun substantially circular, hollow, yielding and practically closed bead I3 which extends upward and outward beyond the intake end of the trap section with the free edge I4 of the bead resting on the end of the wall of the trap section.
The interior wall at the lower end of the waste section is ground out to form a beveled surface I5 and leave an annular rim I6 which is adapted to engage with the rounded surface of the hollow bead I3. The exterior wall I1 of the lower end of the waste section is threaded, and on this thread is screwed a nut I8 that has a iiange I9 which extends under and engages the bead at the end of the trap section when the nut is screwed up to hold the waste and trap sections together. Flanged nuts 20 and 2| are threaded respectively onto the endsof the waste branches 5 and 6 for connecting the branches with waste outlets.
With the nut I8 loose the waste and trap sections are capable of rotation and also a small tipping movement with respect to each other, which permits the several nuts to be easily engaged with the ends of the appropriate conductors regardless of any slight divergence of plane or distance of the ends of the fitting from the ends of the conductors. When the nut I8 is tightened, regardless of slight variations of the alignment of the parts, the trap section and the waste section are bound together water and gas tight and will so remain in a durable manner. The beveled contact surface of the end of the waste section and rounded surface of the bead at the end of the trap section automatically adjust themselves with relation'to each other, and the hanged end of the nut I8 automatically positions itself against the rounded bead with which it engages, when the nut I8 is set tight and the sections drawn together. A slight contraction and possible deformation of the bead which can happen when it is squeezed between the rim at the end of the waste section and the flange of the nut and its free edge is pressed against the end of the trap section, ensures close conformation of the contacting surfaces and a durable and tight joint, which however can be disconnected and reassembled as frequently as necessary without downward below the water level WL of the trap effecting its utility.
As a, result of the construction described the waste section may be connected to two different fixed pipes and the trap section connected to a third' xed pipe and the sections easily and tightly joined by a non-deteriorating conforming seal, even should the ends of the pipes be not exactly leveled or spaced with relation to the ends of the tting.
The invention claimed is:
A coupling for joining two sections of a plumbing fitting, one section having a relatively thin metal sleeve with an end secured in the opening of said section and an end with an outwardly spun substantially circular hollow yielding bead that extends upward and.` outward beyond and has its free edge turnedinward against the wall of said sleeve and resting atwise upon the end of said section, the other section having a threaded end with an opening that has an inwardly beveled wall with a rim which conforms to and is rotatably and angularly adjustable with relation to the upper surface of said circular hollow yielding bead, and a nut threaded upon said second mentioned section and having an internal flange engaging with the under surface of said bead near its free edge, whereby when the nut is screwed up on the threaded end of said second sections, the flange of the nut engages and makes a tight joint with the under surface of the bead and draws the annular rim of the said section against the upper surface of said bead, making a tight joint therebetween, and causes the bead to be compressed so as to make a tight joint with the inner wall of the nut and a tight joint with the upper edge of said rst section as well as with said rim and nut iiange, notwithstanding slight misalignment of the axes of said sections.
