In installing my drain fixture the body 1 is set in the hole previously provided for 5 it in the sub-floor 22 and a sheet of waterproof material 11, which is ordinarily laid over the floor to prevent seepage is laid over the flange 5, a hole having been out in the water sheet of the outer diameter of the The plate 10 is then tightly secured over the material by the bolts 12, thus forming a waterproof seal between them.

The drain fixture 16 is inserted in the bore 2 until the top is almost at the level at which the finished floor will be, and is then given a quarter turn to bring the segmental threads 20 into engagement with the segmental threads 15 and 15 of the body 20 member to secure the drain section therein and to provide a fine adjustment to the level of the finished floor.

The plastic material 24; forming the finished floor is then laid and the grille plate 25 21 is secured in place and my drainage fixture is installed, providing a permanent waterproof seal between the exterior of the fixture and the floor and also adjustable to any thickness of flooring.

By providing the elongate vertical slots in the sleeve portion 17 of the drain section 16, I provide means for carrying oit seepage through the plastic material, which might collect around the exterior of the fixture.

Furthermore, the circumferential ridge 7 about the depression 6 of the flange 5 being on the same level as the plate 10, when clamped in place prevents the said seepage from collecting about its edge, but conducts such moisture as might collect into the bore 2 through the slots 19. i

I claim:

In a floor drain, a body having a tubular bore and an integral lateral flange, a plate formed with an opening to register with said bore, said body having a recess to re ceive the edge of said plate, a sheet of waterproofing material arranged between the 5 plate and body, spaced studs rising from said plate at the edge of the opening there in, a pair of said studs being in diametrically-opposed relation and formed with seg- 7 mental threads, the bore of the body being i formed with corresponding threads, a drain section adapted to lit within said bore, said drain section being formed with diametrically-opposed segmental threads to cooperate with the threads of the studs and bore 0 to secure and permit fine adjustment of the drain section, the relation of the threads on the drain section and studs permitting free :vertical movement of the drain section when such threads are not in registry.
