1- Claim. (Cl. 4--252) This invention'relatesgenerally to carriers for fixtures mounted adjacent to awall such as a water closet or a urinal and it relates more particularly to a novel coupling for use in conjunction with a carrier for a water closet or a urinal.

In prior wall closet carriers, it has been common to use a wall closet fitting with an elongated waterway disposed inside of a wall and a vertically adjustable face plate bolted to the fitting, the face plate having a centrally disposed threaded aperture for threadable engagement with a threaded sleeve having the outer end thereof abutting and in sealed relationship with the back of a water closet. The elongated waterway permits the vertical adjustment of the coupling in the face plate to provide for vertical adjustment of the water closet or urinal. These fittings are costly and there is no provision for adjusting the water closet or urinal horizontally after the wall is built up in front of the fitting or carrier. In these prior fittings, the gasket seal between the coupling and the wall fixture is compressed non-uniformly and it quickly deteriorates and causes leakage. The previous fittings which comprise two or more parts are damaged in many instances when there is any settling of the building or other relative movement between the floors and walls thereof, the parts of the wall engaging the water closet fitting being damaged. It has been particularly difiicult to align these prior water closet fittings, especially where a bank of Water closets is to be installed. In most instances, it has heretofore been necessary to leave the walls unfinished where water closets or urinals were to be installed.

It is, accordingly, an object of my invention to overcome the above and other defects in present water closet and urinal carriers and it is more particularly an object of my invention to provide a coupling for use in conjunction with a carrier for a water closet or urinal which is simple in construction, economical in cost, economical in manufacture, and efficient in operation and use.

Another object of my invention is to provide a coupling for a wall fixture carrier which permits adjustment any time after a wall is in place.

Another object of my invention is to provide a novel coupling for use in conjunction with a carrier for a wall closet or urinal which eliminates difficulties associated with wall type installations such as alignment, wobbly closets, cracked tile from closets being attached to a wall, and the like.

Another object of my invention is to provide a novel coupling for a wall fixture carrier which makes the installation of the Wall closet or urinal simple and efficient.

Another object of my invention is to provide a very simple coupling for a wall fixture carrier which is adapted for use in siphon jet and blow-out type closets and urinals.

Other objects of my invention will become evident from the following detailed description, taken in conjunction with the accompanying drawings, in which Fig. l is a side elevational view of my novel coupling member with parts thereof broken away for better illustration used in conjunction with a carrier for a water closet;

Fig. 2 is a side elevational view of my novel coupling member used in conjunction with a conventional wall closet fitting and face plate of a carrier;

Fig. 3 i; an exploded side elevational view of my novel coupling member; and

Fig. 4 is a side elevational view of my novel coupling 2,702,391 Patented Feb. 22; 1955 ice member with a wrench in axial alignment therewith and spaced laterally therefrom for the lock nut for locking my novel coupling member.

Referring now to Figs. 1, 3, and 4 of the drawings I Show a carrier plate 1 having an aperture 2 centrally thereof internally threaded at 3 (Figs. 3 and 4) for threadably engaging the threaded end 4 of a drainage pipe 5. The plate 1 has an outwardly flanged annular portion 6 which is threaded internally at 7 for threadably engaging the externally threaded sleeve 8 of my novel coupling, the end 9 of the flanged portion 6 of the plate 1 being tapered inwardly. The sleeve 8 has the outer end 10 thereof flared outwardly, the end of the outwardly flared portion 10 sealingly engaging a gasket 12 disposed in a groove 13 on the backside of a water closet 14. The sleeve 8 is rotated in threadable engagement with the threaded portion 7 of the flanged portion l5 of the plate 1 a predetermined amount for adjustment of the flared end 10 thereof with relation to the front 15 of a wall 16, the carrier plate 1 being mounted behind the wall 16. An annular gasket 17 surrounds the sleeve 8 and engages the tapered end 9 of the flanged portion 6 of the plate 1 and is forced against the outer periphery of the sleeve 8 and the tapered end 9 by the tapered portion 19 of an annular, internally threaded lock nut 20. The lock nut 20 has circumferentially spaced projections 22 engageable by the circumferentially spaced, longitudinally slotted portions 23 of a cylindrically shaped wrench 24 as shown in Fig. 4. The lock nut has an enlarged diameter portion and a reduced diameter portion 131 defining a shoulder 133 adjacent the reduced diameter portion 131. The projections 132 extend outward beyond the outer diameter of the enlarged diameter portion 130 at 132. The projections 132 further extend outward from the edge of the reduced diameter portion 131 remote from the enlarged diameter portion 130. The Wrench 24 is so designed that it may be made from any standard pipe. It will thus be seen that the nut 20 may be rotated and tightened even though the wall 16 is in place. In this type of fitting, the aperture 25 in the wall 16 usually formed by a wall sleeve through which the coupling extends is slightly larger than the projections 22 on the annular lock nut 20 so as to permit adjustment of the coupling sleeve 8 in relation to the carrier plate 1 at all times. The water closet 14 is carried by adjustable fixture bolts 26 engageable by bearing nuts 27 and face nuts 27a, the bolts 26 extending through

apertures

28 and 29 in the flanged portions of the water closet 14 and through apertures in the plate 1, respectively. The plate 1 has serrations 30 on the lower end thereof for engaging corresponding serrations 31 on the upwardly flanged portion 32 of feet 33 which are embedded in the floor 34 of a building. A bolt and nut assembly 35 secures the lower end of the plate 1 to the flanged portion 32 of the feet 33.

It will be seen that no special Water closet fitting is necessary with my novel coupling. The carrier plate 1 is connected directly to a drain line. The coupling is adjustable inwardly or outwardly after the wall is positioned. A tight seal is provided. The water closet is not supported on the wall but is given firm support by the carrier plate 1 and supporting feet 33.

In Fig. 2, I show the coupling sleeve 8 with lock nut 20 and gasket 17 the same as in Figs. 1, 3, and 4. The only difference is that the adjustable carrier plate 40 is attachable to the face of a conventional wall closet fitting 41. The plate 40 has an outwardly flanged portion 42 with a tapered end for engaging the gasket 17. The plate 40 has feet 43 attached to the lower end thereof by screw bolts 44. A water closet 45 is attached to the plate 40 by adjustable fixture bolts 46 and suitable bearing nuts 47. A washer 48 is disposed in the groove 49 on the backside of the water closet 45 and engaged by the flared end 10 of the sleeve 8.

The method of installation and operation is the same for the coupling in this type of installation as in the installation shown in Figs. 1, 3, and 4.

It will be evident from the foregoing description that I have provided a novel coupling for use in conjunction with a carrier for a wall type fixture such as a water closet or a urinal which has novel sealing means, which 3 makes installation of the wall fixture cient, and one in which the coupling may be adjusted after a wall is in place. r

Various changes may ment of my invention without departing from the spirit thereof or from the scope of the appended claim.
