An important object of the invention is to combine a bath tub with a lavatory so as to form a single flxture, whereby common water supply m lines to both fixtures, as well as a commondrain,

maybe employed; thereby reducing the cost of installation and the necessary labor to a mini- Another object of'the invention is to construct 15 a bath tub integral with a lavatory so as to provide a single fixture; the lavatory being disposed over a portion of the tub, whereby the combination fixture will cover no more floor spacethan thetub itself, the disposition of the lavatory be- 'ing such as not toreduce the interior space of said tub.

A further object ofthe invention is to provide an improved bath room fixture including a bath tub and a lavatory integrally constructed, and havlng a common ,drain and trap for both tub and lavatory, with independently operated drain plugs, whereby the .tub or lavatory, comprising a single unit, may be used separately. Still another object of the invention is to'prod vide a single improved bath room fixture comprising a bath tub and lavatory, which is so constructed as to require a minimum quantity of piping, vents drains and traps} and which is arranged so that the installation may be accomg-plished with a reduction in cost and labor; the fixture being arranged to permit ready access to the piping, for inspection, at all times after installation. a I

A still further object of the invention is to con- ,m' struct a bath tub and a lavatory as a single unit, thereby not only reducing the original cost and lessening the labor and time necessary for man ufacture, but also eliminating the necessity. of making'two separate flxturea'as is the usual practice.

A typical example of my invention is illustrated and described herein, and the. claims hereinaftr appended set forth the novelty inherent in my invention. 59 In the accompanying drawings:

In the drawings the numeral l0. designates a bath tub which may be of any desired size. The tub is preferably constructed of metal, or other suitable material, and is supported on legs ll. One end wall I2 of the tub may be sloped in the usual way, while the other end wall I3 extends a short distancefrom the bottom of the tub and is then inclined inwardly and upwardly. This end is then extended vertically, to form a wall "M, which is positioned above the top of the tub, as is clearly shown in Figures 2 and 3a A lavatory or wash basin I5 is disposed over the inclined wall H of the tub and is adjacent the wall 14, being made integral therewith. This basin is preferably of the same-material as the tub and in manufacturing it is obvious that the tub and basin may be cast in one piece, thereby greatly reducing labor and material costs. The integral construction of the lavatory with the tub, as well as the disposition of said lavatory over the end. of the same, provide a single unit which covers no more floor space than the tub by-itself. This permits installation of a single unit which has both fixtures, in a space formerly necessary for one.

of this T with the tub faucet 22 and the hot fixtures, and a single source of supply for the hot water to both fixtures. The supply lines are shown in detail in Figure '7. The cold water is conducted from a suitable source ofsupply through an inlet pipe I9 to a T 20. A pipe 2| leads from one side of this T to the tub faucet 22. The cold water control valve H is connected in the pipe 2| and it is obvious that this valve controls the fiow of cold water to the tub faucet 22. The other side of the T 20 is directly connected by a pipe 24 to the cold water faucet |8 of the lavatory, whereby cold water is supplied thereto from the main supply line I9. If desired, a short lead pipe 2| connects the pipes 2| and 21 with a spray head 23, whereby hot or cold water, as desired, may be conducted to said head. A cut-off valve 23' is connected in the line 2|.

Hot water is conducted from a suitable source ofsupply through an inlet pipe 25 to a T connection 26. A lead-in pipe 21 connects one side water control valve I1 is connected in this pipe 21, whereby the hot water supply to the tub is controlled. The other side of the T is directly connected through a pipe 28 with the hot water faucet l8 of the lavatory. Thus, it is obvious that by constructing the tub and lavatory as a single unit, it is possible to use single supply lines for the hot and cold water to both fixtures, thereby not only providing for easier and quicker installation, but also greatly reducing the cost of the necessary piping.

If desired, an opening 29 may be provided in the wall l4 (Figure 7) and this opening is normally covered by a panel 30, which when removed will give easy access to the water control valves for the tub, as well as to the various pipe connections. This makes for ready and easy inspection at all times after installation.

The tub I is provided with the usual drain 3| which is normally closed by the usual type drain plug or stopper 32. The tub also has the usual overflow drain opening 33 in the inclined wall l3. The lavatory is also provided with a drain 34 normally closed by a plug or stopper 35. The usual overflow 36 is provided near the top of the basin of said lavatory. Connected with the drains of both the tub and lavatory, a single 7 drain pipe 31 is provided. This pipe, as clearly shown in Figure 6, is preferably made an integral part of the tub and lavatory and not only serves to conduct the water from the drains but also serves to support the outer end of the lavatory, thereby making for a more substantial structure.

The lower end of the drain pipe 31 is connected to a trap 38 of the usual construction, and a vent pipe 39 preferably-mounted in the wall of the room is connected therewith. From the foregoing, it' is obvious that the tub and lavatory not only are supplied with cold and hot water by a common supply for each, but a sindrained separately, a hand wheel 40 is provided in panel 30 of the wall l4 for the plug 32 of the tub and a similar wheel 4| is provided on the single source of supply for the cold water to both lavatory between the hot and cold water faucets I8 and I8 for controlling the plug 35. The hand wheel 40 is mounted between the control valves l1 and IT in the panel 30 of said wall and is secured to the outer end of a rotatable shaft 42 journaled in said wall and in lug 43. The inner end of the shaft carries a small pulley 44 which has a cable 45 secured thereto. The cable passes downwardly through the space l6 between the lavatory and the inclined wall l3 of the tub, around idler pulleys 46 and 45', and has its lower end fastened to a pivoted arm 41. The outer end of this arm carries a bearing cup 48 which is in constant engagement with the lower end of the drain plug 32. It is obvious that when the hand wheel 40 is rotated the cable 45 is wound on the pulley 44 and the pivoted arm 41 is swung to raise the plug 32 and permit escape of water from the tub. When the wheel is rotated in an opposite direction, the cable is unwound from the pulley 44 and the weight of the plug 32 causes the same to drop into the drain opening 3| to close the same.

The operation of the lavatory drain plug 35 is accomplished in a similar way. The hand wheel 4| is secured on the upper end of a rotatable shaft 49 which carries a pulley 50 at its lower end. A cable has one end secured to the pulley 50 and its other end fastened to the vertical arm of of a bell crank lever 52. The horizontal arm of the lever carries a bearing cup 53 which is in constant engagement with the lower end of the drain plug 35. It will be seen that rotation of the wheel 4| will wind the cable 5| on the pulley 50 which will swing the lever 52 to raise the plug 35 and permit water to drain from the lavatory.

basin.

A recess 54 is provided in the exterior wall of the fixture below the lavatory, as shown in Figure 5, to more comfortably accommodate the feet of the user.

From the foregoing, it is obvious'that a single plumbing fixture, which combines two necessary fixtures, is provided. The advantages are many. The floor space necessary for my improved fixture is only that necessary for the ordinary tub. The manufacturing of two separate fixtures is eliminated, which permits construction at a minimum of cost and labor. The quantity of piping, drains and traps is reduced, thereby decreasing cost and making for easier installation. A complete and compact, as well as a sturdy and attractive unit, without sacrificing efficiency or convenience, is produced.

The pnit may be mounted in a bath room, as shown in Figure 9, and will permit said room to be made smaller than usual without reducing the necessary usable space. The unit may be secured on three sides as shown in dotted lines in Figure 1, or it may be fastened on only two sides as shown in Figure 10. In the latter case, the user may stand at the end when using the lavatory.

In Figures 11 and 12, I have shown another form, wherein the unit is constructed as square in shape. The parts thereof are similar to the form described and a description is unnecessary. It is pointed .out that the unit may be made of any shape or size suitable for the room in which of pressed metal.
