GEORGE H. BARKER, DE LOS ANGELES, CALIFORNIA, ASSIGNOR TO IMPROVED SANI- TARY FIXTURE COMPANY, OF LOS ANGELES, CALIFORNIA, A CORPORATION OF CALIFORNIA.

LAVATORY APPLIANCE.

To all whom it may concern.

Be it known that I, GEORGE H. BARKER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Lavatory Appliances, of which the following is a specification.

My invention relates to lavatory appliances and has particular reference to a novel combination bath tub and wash bowl and the waste connections for each thereof.

In the designing of many bat-h rooms the question of available space is an important one. It not infrequently occurs that a fullsized bath tub may not be located within a given space and at the same time provide for a wash bowl.

One of the objects of my invention is to provide a combined bath and wash bowl in such manner as to economize in fioor space and at the same time economize materially in the plumbing required for the installation of such fixtures.

I am aware that combined wash stands and bath tubs are not new but believe the waste connections for the tub and bowl, as shown in this application, are new.

In plumbing ordinances it is customary to fix or limit the amount of pipe which may be exposed to fouling on the house side of any trap. This result is ordinarily accomplished by regulating the number of fixtures without individual traps which may be attached in series to a given waste pipe of stated size. A most common example of this procedure is the installation of laundry tubs, which, under plumbing ordinances are variously permitted to be connected with a single trap in groups of from two to four.

Naturally the attempt should be made to reduce to a minimum the fouling surface on the house side of any trap. It is apparent, however, that it is not the area of surface exposed but the amount of decomposable organic matter which will have an opportunity to deposit upon this surface which is significant. It is probable that many tures in buildings are so infrequently used that the trap seals become broken through evaporation. Thus a very large fouled surface may become exposed to the atmosphere of a room. Any greater use which would obviate loss of seal through trap evaporation should be Welcome.

ing two fixtures, such as those under consideration, with a minimum length of waste and each having a waste pipe virtually independent to a point in close proximity to the trap, will be maintained more effectively in seal and will be cleaner and better scoured than if two traps were used, one on each fixture.

An important feature of this waste pipe system is the vertical section of pipe, serving the lavatory, within the larger bath waste. This pipe fulfils a double purpose inasmuch as it increases the scouring velocity and in addition prevents splashing and consequent undue fouling of the overflow and waste from the bath tub itself. In other words, these outlet pipes from the bath will, with the stated arrangement, be just as clean in this combined fixture as in those of an independent bath tub.

lVith the waste connections as herein shown it will be seen that one trap will serve for both fixtures and that thereby the cost of installation is materially reduced.

My invention will be more readily understood by reference to the accompanying drawings wherein Figure 1 is a side elevation of a combined bath tub and lavatory with my novel waste connection applied thereto; Fig. 2 is an enlarged vertical section through the waste pipes shown in Fig. 1. Fig. 8 is an enlarged vertical section through a modification of the construction shown in Figs. 1 and 2.

Referring more particularly to the drawings, it will be seen that I provide a bath tub 10 of any preferred construction, from the lower portion of which extends a waste pipe 11 and near the upper end of which is an overflow pipe 12. Mounted above the tub 10 is a lavatory 13 suitably supported on the rim of the tub and provided with a waste pipe 14. As shown in Fig. 2, the Waste pipe from the lavatory, the opening to which is controlled by a stopper 15, extends downwardly into a connection 16 being held therein by a union nut 17. Suitably secured to the pipe 11 at a point within the connection 16 is a smaller pipe extension 18, this smaller pipe extending down and terminating at a point considerably below the outlet 11 for the tub. The location of the pipe centrally of the larger pipe 19 provides a space therearound through which water may escape from the overflow 12. The waste connection 11 opens into a connection 20, similar to the connection 16 and this connection 20 is directly connected to a pipe 21, in which the trap (not shown) is located.

It will be noted that the overflow from the lavatory is conducted directly to the: main discharge pipe 21, and has no oppor tunity to foul any of the bath connections. Furthermore, that the waste connection for the bath is arranged to discharge almost directly into the main discharge pipe with practically no fouling surface. An obvious advantage in this construction is in that the single trap serving the lavatory and bath has no opportunity to become broken due to evaporation, as frequently occurs in the case of an infrequently used bath. The constantly used lavatory will keep the trap flushed and prevent the breaking of the seal. In order to supply clean water to the bath the lavatory and the tub I provide a twoway bib-cock 22, one portion discharging into the lavatory and the other into the tub. A valve 23 controls the passage of the liquid into one or the other of the receptacles. In the modified construction shown in Fig. 3, the waste pipe 14;, discharges into a double passage waste pipe, the two passages being formed by a dividing web secured internally of the pipe. In Fig. 3 the lavatory discharges from the pipe 14 into a pipe 24, which pipe is flattened and one-half thereof removed as at 25, the remaining portion of the pipe being bent in such manner as to form a partition 26 extending downward through the pipe 27, and ,at a point past the lower T 28.

I claim:

.1. The combination with a bath tub and a basin located above the tub, a drain pipe connected to the tub, and a drain for the basin consisting of a connection imperforate with respect to the tub connections and extending from the basin down through the tub drain pipe and terminating below the tub drain whereby to prevent back flow of the water from the basin.

2. The combination, with a bathtub and a basin located above the tub, a drain and overflow pipe connected at its upper end to the upper part of the tub and also having a connecting branch extending to the lower part of the tub, and an imperforate drain pipe extending from the basin down through the first pipe and terminating at its lower end below the connecting branch of the tub drain whereby to restrict back flow of water from the basin.

In testimony whereof I have hereunto signed my name in the presence of two sub scribing witnesses.

GEORGE H. BARKER.
