V'Ihepresentinvention pertains to a novel adjustable and leveling floor drain` head of the type commonly employed inv shower baths although applicable also to other surfacesto be drained.

`:'I'heassembly` for` this Ypurpose comprises a trapor other receiver in which the drain head directlythereinr .Accordingly, it is customary to prow/idea oating or adjustable mounting inthe receiver `for the purp-oseof `taking the drain head member. In onecommon form of con.-

the receiver or trap after the latter has been assembled. This' method requires that the plumber carry the melting equipment to thefjob these difficulties `in a device that is durable,l

simple in construction and comparatively low in In this device, the drain head member is an auxiliary member carrying the strainer is adjustably mounted on the topi of the drain head More specically, the upper end 'Hof the drain head member is in the form "of a spherical seat, and the auxiliary ,member` is a sphericalr bowl having universal adjustability on the seat.` This bowl carries the strainer plate. When the top of the bowl hasbeen leveled to the floor and before mounting of the strainer plate, the bowl is secured in the proper adjustment on the seat, by suitable fastening devices, and the strain-er plate is then applied. This arrangement does away with floating or adjustableparts in the receiver or trap and provides a device that is readily installed without calking, leading or similar operations'. lurther;v by reason of the integral character of the'upper end yof the receiver or trap, the sheet lead pan usually mounted upon the last named lmember is more readily secured in place.` For this purpose, the threaded'v part of the head member carries a clamping nut by means of which the lead pan is secured div rectly on the upper end of the receiver or trapt The invention is fully disclosed by way of example in the following description andin the accompanying drawing, in which Figure lis a vertical section of an assembly according to the invention;

use of like characters that are employed to desig-` nate corresponding parts throughout.

In Figuren is `illustrateda trap IL ofl more or less conventional designvhaving a lateraloutlet 2 to be coupled to a waste pipe that usually stands` vertical. It will be understood that the trap as well as vthe drain head, presently to be described, lies beneath the surface to be drained.

. The upper end of the trap is tapped at 3 for` direct insertion `of the drain head; and in this respect differs from many traps for this l'aurposey which are provided with a floating or adjustable tapped ring to receive the drain head. The drain head, according.v to this invention.,

is a tubular member 4 having its upper .end

flared` at 5. `The tubular portion is externally threaded at 6 to be screwedinto the tapped end 3 of the trap, as` clearly illustrated" in Figure 1. seepage channels 'I are preferably cut across the breadths oran obvious purpose.

` In the iiared end or inlet 5 is formed a seat 8` which is preferably conical for a purpose presently to be described. On the seat is mounted a bowl 9 similarly shaped on its 4outersurface ade` 'jacent to theseat.

universally adjustable in the seat 8 of the inlet 5L Thus, the "members 5 and 9 are related `toeach other as the .elements of a vball and socket joint, whereby the bowl 9 Vis in the `top of the bowl 9 is mounted a strainer I j i0 held by screws II passingtherethrough and into tappede lugs I2 on the bowl, as shown in Figure 3.

The inlet 5 is formed witha suitable number` of tapped holes I3 adjacent to which isa considerably larger hole I4 in the wall ofthe bowl. `Two such sets of holes are preferred, although 'l one may suffice. Over each hole I4 is` a washerv l5 suitably dished to seat in thefbowl and preferably of such size as to cover the hole I4. The holes I4 are of such size as to register with the holes I3 in any likely adjustment rof "the bowl onY the seat 8. After the adjustmentis made, the

line up on the desired vertical axis. Consequentscrews It passing throughthewashers and holes ly, in prior devices, theV drain does not'` screw directly into the trap but rather into a iioating` or adjustable ring that mustbe setin the top ofthetrap, as by means of calking orleadlng.

Either of these operations is time-consuming and further require that the plumber bring the necessary melting equipment to the job. This dini- `culty, as well as the inconvenience of`melting onthe job, is avoided in the present invention wherein the drain head is screwed directly into the trap as already set forth. The bowl 9 carrying the strainer is brought to the height of the iioor by screwing the head more or less into the trap, and is leveled 'with the floor by adjustment of the bowl on its seat'.

' the washers l5 and screws I6 may be pre-assembled in loose condition and the'screwstightened M after the strainerhas been leveled.

rIhe upper end of the trap l is formedk with a e wide flange il for supporting the usual sheet lead pan i8. On the threads i5 is a clamping nut i9 forsecuringthe pan IS against the upper end of thetrap, This securing operation is also yfacilitated and simplified, by the meansv described, because oithe absence of oatingfor otherwise adjustable parts in the upper end of the trap.

Although a specific embodiment of the invention has been illustrated and described, it will be understood that various `alterations in the details of, construction may be made without departing from the scope of the invention, as indicated by the appended claims. f l

' What I claim is: K

1. A drain head assembly comprising a tubular head member, having a spherical seat in its upper end, a bowl of 4substantial depth having a spherical portion iitted in said seat and rotatably adjustable therein, a strainer carried by said bowl,

As a matter of practice,k

said head-'member having holes through said seat and said bowl having larger holes registering with the first holes, and securing means passing through the registering holes.

2. A drain head assembly comprising a receiver, a tubular head member threaded directly therein,

a bowl mounted and universally adjustable onv membenand a nut `on the threaded portion of said head member and adapted to clamp a lead pan againstv said receiver.

4. A drain head assembly vcomprising a re. cciver, a tubular head member threaded directly therein and having'a spherical seat in its upper end, a bowl of substantial depth having a spherical portiony fitted irl said seat and` rotatably adjustable therein, a strainer carried byA said bowl,
