Abstract:
This invention is an improved sealing means for use in conjunction with water closet rings wherein a lower section includes an inwardly beveled shoulder which fits a similar configured neoprene type gasket. When a specially designed top section telescopically engages the interior of the lower section, the gasket is expanded to form a water tight seal about the drain pipe or other member associated therewith.

Description:
FIELD OF INVENTION 
     This invention relates to plumbing fixtures and more particularly to improved sealing means for use in conjunction with water closet rings. 
     BACKGROUND OF INVENTION 
     Water closets and their associated water closet rings have, of course, been in use for many years and secure the water closet to its associated drain pipe. The time accepted procedure using cast iron pipes has been to place the closet ring about the pipe so that it rests on the floor of the room and then fill in the tapered area between such pipe and such ring with lead and oakum to seal the two together. 
     With the advent of plastic drain pipe, lead and oakum could no longer be used because when heated to a liquid state, it would melt the pipe adjacent the ring. 
     Various arrangements have been experimented with to meet changing product requirements including the use of sealants other than lead and oakum. None of these substitute sealing means between water closet ring and drain pipe until now have been as satisfactory as lead and oakum used in conjunction with cast iron pipe. 
     BRIEF DESCRIPTION OF INVENTION 
     After much research and study into the above-mentioned problems, the present invention has been developed to provide an improved gasket means for water closet rings which can be used equally well with cast iron pipe and plastic or PVC pipe. No heating or pouring is required to affect the seal between the ring and the pipe and the seal itself should remain effective throughout the useful life of the system. 
     The above is accomplished through the provision of a bottom section having a beveled, interiorly projecting shoulder which is adapted to juxtaposingly receive a gasket composed of a plyable material. A top or upper section is then placed on the upper edge of the gasket and once the pipe has been properly positioned, draw down means are used to squeeze the gasket between the top and bottom sections to cause the same to expand against the pipe creating a water impervious seal between said ring and said pipe. 
     In view of the above, it is an object of the present invention to provide a two piece closet ring in combination with an improved gasket for effecting a water tight seal between such ring and its associated drain pipe. 
     Another object of the present invention is to provide a sealing means including a first portion having an interiorly beveled shoulder adapted to receive a gasket means and a second portion adapted to be telescopically inserted into said first portion whereby said gasket can be caused to form a seal with an adjacent inserted structure. 
     Another object of the present invention is to provide a neoprene type gasket used in conjunction with a two piece closet ring for effectuating a moisture impervious seal between such ring and its associated drain pipe. 
     Another object of the present invention is to provide, in a water closet ring, a beveled shoulder against which a neoprene type gasket is pressed to effetuate a moisture impervious seal against an adjoining pipe type means. 
     Another object of the present invention is to provide a two piece closet ring using corrosion resistant bolts to draw the parts together against a neoprene type gasket to effectuate a seal with an adjoining pipe. 
    
    
     Other objects and advantages of the present invention will become apparent and obvious from a study of the following description and the accompanying drawings which are merely illustrative of the present invention.

     DETAILED DESCRIPTION OF THE INVENTION 
     With further reference to the drawings, the two piece closet ring of the present invention, indicated generally at 10, includes a top section indicated generally at 11 and a bottom section indicated generally at 12. 
     The bottom section 12 is formed in a generally ring-like configuration having an exterior 13 and an interior 14. The lower portion of the interior 14 includes a beveled, interiorly projecting shoulder 15 as can clearly be seen in FIG. 2. 
     A resilient, plyable gasket 16 composed of neoprene or similar material is provided. This gasket is ring-like in configuration and includes an exterior surface 17 and an adjoining beveled surface 18. This gasket 16 also includes an upper end surface 19 having a centrally disposed groove 20 formed therein. Finally the interior surface 21 of gasket 16 includes at least two inwardly projecting sealing ribs 22. 
     The top section 11 includes a ring portion 23 having an exterior surface 24 and an interior surface 25. To the upper edge of ring portion 23, as disposed in the drawings, is provided an outwardly disposed closet flange 26. This closet flange includes a plurality of smooth bore openings 27 therein which are adapted to receive pull down means such as bolts 28 formed from stainless steel or other suitable corrosive resistant material. 
     A plurality of bolt tabs 29 are provided on the exterior 13 of bottom section 12. Each of these tabs has a threaded opening 30 therein to receive bolts 28. 
     To use the closet ring of the present invention, an opening is provided in floor 31 having a diameter less than the diameter of closet flange 26 but greater than the greatest distance between opposed bolt tabs on the bottom section 12. 
     A drain pipe 32 is centrally disposed in the opening in floor 31 and projects above the plane thereof. 
     Next the gasket 16 is inserted into the bottom section 12 so that its exterior surface 17 lies juxtaposed to interior surface 14 and such gasket&#39;s beveled surface 18 lies juxtaposed to beveled shoulder 15. 
     Top section 11 is telescopically inserted into the interior of bottom section 12 until lower surface 23&#39; rests against the upper surface 19 of gasket 16. Bolts 28 are then passed through openings 27 of top section 11 and threaded into openings 30 of tabs 29 of bottom section 12 until barely snug. 
     The now assembled two piece closet ring 10 is next slipped over pipe 32 until the bottom of flange 26 engages the upper surface of floor 31 and rests thereon. Bolts 28 are then tightened down thereby pushing gasket 16 downwardly against beveled surface 15 which forces such gasket inwardly against pipe 32. Sealing ribs 22 compress more readily than the remaining portions of gasket 16 and, therefore, will conform to any surface irregularities in pipe 32 thereby insuring a moisture proof seal between the top section 11, the bottom section 12, and the drain pipe 32. 
     Groove 20 in the upper surface 19 of gasket 16 allows such gasket to expand further thus assuring a good seal between the upper rib 22 and the exterior surface of pipe 32. 
     Finally the water closet (not shown) can be installed in the normal manner above closet ring 10 and its associated drain pipe 32. 
     From the above it can be seen that the present invention provides a relatively inexpensive and yet highly efficient means for sealing a closet ring to its associated drain pipe regardless of the type of material from which such ring or such pipe are formed. The present invention is simple to assemble and install while at the same time insuring a moisture impervious seal. 
     The terms &#34;upper&#34;, &#34;lower&#34;, &#34;top&#34;, &#34;bottom&#34;, and so forth have been used herein merely for convenience to describe the two-piece closet ring and its part as oriented in the drawings. It is to be understood, however, that these terms are in no way limiting to the invention since the ring may obviously be disposed in different orientations when in use. 
     The present invention, of course, may be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristics of the invention. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended Claims are intended to be embraced therein.
