D. CRAIG. PIPE UNION. APPLICATION men MAY 4. 1914. ' Patented Feb. 13, 1917. jvaarafifr 2 id Cray n STA 1 DAVID CRAIG. 0F PEABODY, MASSACHUSETTS. PIPE-UNION. Application filed May 4, 1914. Serial No. 836,101. To all whom it may concern: 7 Be it known that I, DAVID CRAIG, a citizen of the United States, and resident of Peabody, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Pipe-Unions, of which the following'is a specification. I This invention relates to pipe unions for connecting the outlet end of a plumbing fixture, such as a bowl or stool, to the top of a soil pipe, and consists in the novel and improved structures hereinafter described and more particularly pointed out in the claims. In the accompanying 'drawings which illustrate one embodiment of the invention, Figure l is a central, longitudinal section of the pipe union; Fig. 2 is a plan view of a stool and seat in which said union is employed; and Fig. 3 is a rear view of said stool and seat. A represents the floor on which the stool B rests, and C is the soil pipe extending upward into, but not completely through a hole in the floor. D is a hub, made with a flange d, resting on the floor, the hub D extending downward a short distance into the top of soil pipe C. The flange d is firmly secured to the floor by screws or bolts, and is provided with an upwardly extending marginal rim cl, which forms a cup surrounding ring F, hereinafter described. i/Vithin the hub D is a sleeve E, extending both above and below the hub D, and provided with a series of annular rims e on its inner surface. The upper end of sleeve E is screw-threaded and has screwed thereon a ring or collar F extending outwardly over flange cl. Below hub D, the sleeve E is provided with a collar 6, which makes a loose fit with the interior of soil pipe C. The base of stool B, which may be of porcelain, rests on the floor and is recessed or countersunk at its lower end adjacent to the outlet passage B, to provide a shoulder b and a recess 6 for flange cl and ring F, screwed on to sleeve E above flange 03 Between the upper end of sleeve E, and the shoulder b, is a packing G of suitable material, adapted to seal the joint between the sleeve E and the o'utlet passage B. And between the lower end of hub D, sleeve E and the collar 6 is another packing I-I, adapted to seal the joint between sleeve E and the soil pipe C. Rods J, J are threaded at their lower ends into ring F, and extend upward through the stool 13, their upper ends being provided with heads K, K, which also serve as the hinge members for the seat L, when the parts are assembled. I When the parts are in the position shown in Fig. 1, the rods J are screwed up tight, thereby lifting ring F and sleeve E, which compresses .both the 'packings G and II and insures a tight connection between outlet passage B and soil pipe C. At the same time the stool B is clamped solidly down on to the floor, the same rods J being used for holding the stool in position and for holding the seals tight between the passage B and the soil pipe C. No exterior bolts for securing the stool to the floor are required, and if it is desired to gain access to the soil pipe for the purpose of repairing or cleanf ing, it is only necessary to unscrew rods J, J and lift the stool B out of the way. The ribs 6 on the inner surface of sleeve E tend to deflect the water coming downward toward the center of the pipe and to increase and emphasize thesiphonic action in the bowl of the stool. Said ribs may be made with horizontal top deflecting surfaces like the two upper ribs shown in the drawings, or they may be part one Way and part the other, according to the abruptness desired in the deflection of the water. I claim: 1. In combination, the outlet end of a plumbing fixture, a soil pipe, and a union therebetween comprising an interior sleeve extending into the soil pipe and having thereon an annular collar, a hub extending between the soil pipe and said sleeve, and a packing seal between said hub, soil pipe and collar. 2. In combination, the outlet end of a plumbing fixture, a soil pipe, and a union therebetween comprising an interior sleeve extending into the soil pipe and having thereon an annular collar, a hub extending between the soil pipe and said sleeve, a packing seal between said hub, soil pipe and collar, and a packing seal between said sleeve and fixture. 3. In combination, the outlet end of a plumbing fixture, a soil pipe, and 'a union therebetween comprising an interior sleeve extending into the soil pipe, a hub extending between the soil pipe and the sleeve having a flange extending over the floor, a ring secured to the sleeve above the hub flange, a packing seal above said ring between the sleeve and fixture, and a packing seal between said sleeve and soil pipe. 4. In combination, the outlet end of a plumbing fixture, a soil pipe, and a UIliOIl therebetween comprising an interior sleeve extending into the soil pipe, a hub extending between the soil pipe and the sleeve having a flange extending over the floor, a ring secured to the sleeve above the hub flange, a collar on said sleeve below the hub, and a packing seal between said collar, soil pipe and the end of the hub. 5. In combination, the outlet end of a plumbing fixture, a soil pipe, and a uniontherebetween comprising an interior sleeve extending into the soil pipe, a hub extending between the soil pipe and the sleeve having a flange extending over the floor, aring secured to the sleeve above the hub flange, a collar on said sleeve below the hub, a packing seal between said collar, soil pipe and the end of the hub, and fastening connections between said ring and said plumbing fixture adapted to draw and hold both' of said packing seals tight. 6. In combination, the outlet end of a plumbing fixture, a soil pipe,-and a union therebetween comprising an interior sleeve extending into the soil pipe, a hub extend ing between the soil pipe and the sleeve having a flange extending over the floor, a ring secured to the sleeve above the hub flange, a collar 011 said sleeve below the hub, a packing seal between said collar, soil pipe and the end of the hub, and fastening-connections between said ring and said plumbing fixture adapted both to draw and hold said packing seals tight and to secure said plumbing fixture in position. .7. Incombination, the outlet end of a plumbing fixture, a soil pipe, and a union therebetween including an interior sleeve extending into the soil pipe, a hub extending between the soil pipe and the sleeve having a flange extending over the floor, a ring secured to the sleeve above the hub flange, a collar on said sleeve below the hub, a packing seal between said collar, soil pipe and the end of the hub, and rods screwed into said ring and extending upward through the plumbing fixture, said rods serving both to hold said packing seals tight, and to fasten said fixture in position. '8. In combination, a stool, a soil pipe, a union therebetween including a packing seal, and rods connected to said union and extending upward through the stool, serving both to hold said packing seal tight and to fasten said stool in position, and also serving as hinge members for the stool seat.
