18 Claims.

This invention relates to a combination plumbing fixture, and is more particularly directed to abathroom fixture comprising a bathtub, water closet and lavatory ensemble or unit.

In the ordinary bathroom as now designed, the bathtub, water closet and lavatory are separate units, each independently and separately mounted and supported, with individual piping ,connections to each unit. Thus, the lavatory is provided with hot and cold water connections and also a waste connection, and since it is of considerable weight, is also ordinarily provided with support- ,ing legs or a standard which is secured to the floor of the bathroom, since ordinarily the weight of such a structure is not capable of being supported upon the wall. The water closet is provided with a flushing connection and a waste connection, which must be led through either the wall or floor, and means must also be. provided for firmly supporting the device upon the floor in upright fixed position.

These piping and supporting means render it extremely difficult to maintain the bathroom in the desired clean and sanitary condition, since it is practically impossible to maintain the floor and wall clean above the water closet and the lavatory. Further, the visible piping connections which project through the wall or floor are both unsightly and unsanitary, since they provide a plurality of surfaces for catching and retaining dirt, dust and the like. In addition, the use of such individual units requires cutting up of the floor and floor joints, and produces an obstructed floor which is hard to maintain clean.

It is an object of the present invention to provide an ensemble unit comprising a bathtub, water closet and lavatory, the closet and lavatory being mounted upon the front face of the tub, whereby the unit is easy to maintain clean, occupies little space, and provides a compact, neat appearing installation which does not obstruct the floor or walls of the bathroom, and consequently the cleaning and maintenance of a neat and sanitary bathroom is facilitated. Furthermore, all water and waste piping is concealed,

with no piping projecting through the walls or floor, which eliminates the unsightly appearance of prior types of bathroom fixtures of which I am aware.

' The preferred embodiment of the present invention provides a bathtub structure having a front panel or wall upon which is mounted, by means of integrallyfianged curved brackets or pedestals, the water closet and lavatory, thus re- 'quiring no goor supports for $111258 structures,

since they are supported in raised position 03 of the floor and upon the face of the tub. The water connections are all disposed rearwardly of the front panel or face of the tub, entering directly into the water closet or lavatory through the tub panel, whereby they do not project through the walls or floor of the bathroom, and are completely out of sight.

In prior installations of which I am aware, the "roughing in" operations for connecting the piping to the various fixtures was complicated, and required from four to five feet of wall space. By the present construction, these operations are considerably simplified, and the wall space required is therefore reduced approximately 50%. The present invention provides an ensemble ner tub construction, in which the tub is secured which is adapted for either right or left hand corin a corner of the room, and has an end and side wall projecting free from the walls of the bathroom, or for a recess type of tub construction, which latter case only the front face of the tub is open, the remaining sides engaging the walls of therecess. The tub and the fixtures may be provided with any desired type of design and color combination, and the lavatory may be made of vitreous china or enameled iron, as desired. The

closet can be of any preferred type, such as a vision of waste pipes for the water-closet and lavatory which are provided with oppositely threaded ends, so that rotation of the pipe during assembly or installation secures it simultaneously in position at both ends.

In some municipalities, a horizontal run of waste pipe of over three or four feet from a vent is prohibited, and in such instances the present construction is so designed that an anti-syphon type of lavatory trap may be employed. In this connection, the lavatory and water-closet are interchangeable in position with respect to the tub, so that the water-closet may always be placed in proximity to that end of the tub which is adjacent the waste riser connection.

In order to provide for uniformity of construction, the panel of the tube is provided with spaced sets ofcut-out openings, each set being capable of accommodating either the water-closet or lavatory. Since the water-closet does not require the openings necessary for the faucet connections of the lavatory, and the lavatory does not require the flush valve opening required by the water-closet, these openings are suitably closed by ornamental fittings when not in use.

The two ends of the tub proper are also provided with corresponding sets of openings for faucet connections, the unused set of openings being covered by a suitable ornamental fitting, such as a soap dish or the like.

In order to provide for rapid and simplified assembly of the unit, I provide a manifold having two chambers, one connected to a source of hot water supply, and the other connected to a source of cold water supply. From these chambers, suitable flexible conduits, such as copper tubing or the like, are led to the various faucet connections and to the flush valve connection for the water-closet. This provides for ready installation of these connections with a minimum amount of labor.

Other objects and advantages of the present invention will appear more fully from the following detailed description, which, taken in connection with the accompanying drawings, will disclose to those skilled in the art the particular construction and operation of a preferred form of the present invention.

Referring now in detail to the embodiment of the invention shown in Figures 1, 2 and 3, I have provided a. tub, indicated at l2, which is provided with the recess portion I3 comprising the water receiving portion of the tub, and is also provided with the front panel or face H, which may, if desired, be recessed or beveled, as indicated at l5, to provide a suitable design or the like thereon.

Secured to the front face of the tub is a lavatory indicated generally at l5, provided with a wash bowl or basin I1, and also provided with an extending pedestal or supporting portion [8, which terminates in a flanged bracket surface l8 extending normal to the plane of the lavatory 18.

and provided with a pair of threaded bolt members 28 adapted to thread into the front face I of the tub, the metal of the tub being preferably thickened at this point, as indicated at 2!, to provide an adequate support forthe pedestal. 5 The lavatory I8 is also provided, as shown in Figure 6, with an inner extending flange portion 23, which is bolted, by means of bolts 24, to the upper surface of rim 25 of the tub, there preferably being several of such bolt connections dis- 0 posed on opposite sides of the center of the lavatory.

Extending centrally between the bolted portions 23 of the lavatory are the flexible water connections 25 and 21 extending to the faucet fixtures 28 of the lavatory, these connections passing through an opening 29' formed in the rim 25 of the tub. Preferably, the cold water connection is indicated at 25, the hot water connection being shown at 21, and these connections are extended into a valved housing member 28 secured to the under-surface of the upper rim of the lavatory i6, and controlled by the faucet members 32 and 33. The faucet itself is indicated at 84, being directed into the bowl H. The fixture 28 is also provided with the operating member 35 which controls the stopper means 88 mounted in the drain 31 of the basin l1.

' The drain 3! is connected through the pipe 88, anti-syphon trap 39 and pipe 48 to a waste connection elbow 42, the pipe 40 being connected to the waste connection through the opening 43 in the front panel of the wall II. The pedestal or bracket I8 is provided with an opening 44 which permits access to anti-syphon trap 39, in order to permit inspection, removal and cleaning of the same.

Secured in spaced relation to the lavatory l8, and mounted upon the front face or panel ll of the tub i2, is a water closet indicated generally at 50, which water closet may be of any standardv type, such as a syphon-jet operating closet, or a wash-down or blow-down type. The closet 58 has the depending portion 5| provided with an annular flange 52, which flange is bolted or other- 45 wise suitably secured to the front face I of the tub by means of bolts 58 disposed on opposite sides thereof. The closet seat is indicated at 54, and is provided with a cover 55 hinged as shown at 56, in the ordinary manner. A suitable flush valve, shown at 51, is extended through the wall H, and controls the flushing action of the water-closet 50. The interior of the depending portion 5| of the bowl 50 is connected, through an angle or elbow 58, to an intermediate waste pipe 59, the member 58 being adjustable in position as shown in detail in Figures 7 and 8 to accommodate roughing in of the same.

Considering now Figures 7 and 8, the interior of the bowl 50 and depending portion 5| thereof 60 is connected, through the conduit or outlet 85, to the elbow 58, the elbow 58 being provided with a cylindrically flanged portion 82 having a beveled edge 63. The rear face of the wall I is provided with a pair of angularly extending dovetail portions 84, which are spaced apart a distance equal to the diameter of the flanged portion 82 of the elbow 58, and the elbow 58 is adapted to have relative movement longitudinally of the members 84 while the waste pipe 55 is being connected thereto, to accommodate roughing in of this pipe.

The tube itself is provided with a faucet 85, con nected through the fixture 88 to a pair of water supply pipes 61 and 58, as shown in Figure 2.15

' corresponding valve members 99 and 19.

. In providing the hot and cold water connections for the lavatory I9 and the tub I2, I preferably provide a manifold indicated at 12, which has a cold water chamber 13 and a hot water chamber 14, the two chambers being preferably separated by an insulating member for preventing transmission of heat therebetween. The cold water chamber 13 is connected, through valve 15, to a cold water supply pipe 19, while the hot water chamber 14 is connected, by means of valve 11, to a hot water supply pipe 19. From the cold water supply chamber 13, flexible connections, comprising copper tubing or the like, are led off to the tub and lavatory, comprising the connections 91 and 29, respectively. Similarly, the pipes 99 and 21, for supplying hot water to the tub and lavatory, respectively, are connected on the hot water side of the manifold 12, that is, to the chamber 14. The connection 19, leading to the hush valve 99 controlled by the valve member 51, is connected to the manifold 12, and from the flush valve chamber 99 is connected through the member 82 to the water-closet 59, as is well known.

The tube I2 is provided-with a drain 99, which is connected to a suitable drum trap 94 by means of an over-flow riser 95 positioned beneath the rim of the tub and extending vertically upward with respect thereto. From the drum trap 94, the waste pipe connects the drain to the common waste line 91. g

A waste riser for the building is indicated generally by the numeral '99, and is provided with the usual unvented T member or fitting 92, to which is connected the waste pipe 91, which preferably extends at a slight angle to the horizontal, sloping toward the drain or riser 99. In older buildings, in which a waste stack is already. in place outwardly of the tub, the waste connection 21 may be extended outwardly to the stack. The waste pipe 81 is adapted to receive the waste from the tub through the drum trap 94, and the waste from the lavatory I6 through the waste pipe 93' connected to the elbow 42 which communicates with the waste pipe 49 of the lavatory, which waste pipe 99 is connected into a second T 94 disposed at a higher level than the T 92. The

waste from the water-closet 59 passes through the pipe 59 to the end elbow member 95, which has the offset connection 96 for receiving waste from the T connection 94 connected to the lavatory waste pipe 93. Extending upwardly from the T connection 94 is a vent pipe 91, which is set into the upper connection 99 of the T 94, and at its opposite end is threaded into a triple elbow fitting 99. The vent for the water-closet 59 comprises the extending bell fitting or slip hub I99, receiving the lower end of a vent pipe l9I which is threaded at its upper end into the fitting 99. The vent for the tub waste pipe 86 comprises the fitting or slip hub I92, which receives the lower end of the vent pipe I93 threaded at its upper end into the fitting 99. The elbow 99 is connected through pipe I94, to a second waste riser T I95 connected to the waste riser 9.9. Thus it will be seen that the vent means for the tub, lavatory and watercloset are combined into a single vent I94 leading to the waste riser.

The assembly of the pipes 91, I M and I93 within their corresponding fittings .at thelower ends thereof is in the usual manner, the pipes being droppedinto the fittings, and then slightly raised as they are threaded at their upper ends into fitting 99. The space between the outer surface of the pipes and the inner periphery of s the bell is then caulked and filled with suitable sealing material, such as lead or'the like. Similarly, the connections between the fittings 92 and the riser 99, and the connections between the member 94 and the elbow 95 are completed in the 10 .same manner.

, It is to be noted that the waste pipes 59 and 93 are threaded in opposite directions at the ends thereof, so that when mounted into position, rotation of the pipe will result in threading of the 15 same at bothends thereof, thus requiring only a single operation to complete the connection of the pipe at both of its ends. During this rotation, the beveled flanged portions of the elbows 42 and 59 are moved longitudinally of the locking dove- 20 tail strips 64 as shown in Figures '1 and 8, and the required roughing in operation is easily ac-v commodated by means of this construction.

It is thus apparent that all of the piping connections for both the lavatory and water-closet, 25 as well as for the tub, are concealed from view behind the front wall I4 of the tub, and extend between this wall and the recess portion I3 of the tub proper, beneath the upper rim 25 of the tub. As shown in Figure 1, the tub I2 is of the so recess type, being adapted to fit between walls I96 and I91 which. are diagrammatically indicated in this figure. With a corner type of tub, in which one end thereof is e p ed as well as the front face, the same construction can be em- 35 ploycd without any difficulty.

By the provision of flexible tubing for the conduits 29, 21, 61, 68 and 19, it is possible to facilitate the connection of these members within the relatively small space provided, since they may m be bent into the desired angles and readily connected. Further, by the provision of the trap 39, which is easily accessible through the opening 44, and the provision of the trap 84 which is accessible from the end of the tub, it is possible to maintain the waste line for the tubrand lavatory in proper condition at all times. By reason of the trap 94, it is impossible for the waste from either the water-closet or the lavatory to back up into the drain for the tub. Similarly, by providing the entrance of the pipe 93 at a point above the waste. pipe 59, the waste from the water-closet cannot back up into the lavatory I9. Thus, the present construction prevents backing up of the waste lines for any of the units .comprising the ensemble fand also provides a common vent for all three of the waste lines.

Referring now to the structure shown in Figures 4 and 5, a tub member is indicated at II9, provided with the recessed portion II2 defining 0 the tub proper, and provided with a horizontally extending rim portion indicated generally at II3. Integrally formed supporting webs or flanges H4 and II 5 are provided for spacing the tub with respect to the floor, these reenforced webs serving to support the tub in fixed position. The front face of the tub comprises the planar surface II5, which is formed integrally with the rim I I3, and which extends down to the floor level. The member I I9 may be formed of enameled iron or the like. On opposite ends of the member, openings ampipvided, as indicated at H1 and 1', for receiving the faucet connection, shown in Figure 5 by thereference numeral II 9. This faucet connection includes the faucet II9 opening into the tub portion II 2, and also includes the connections, such .as described in connection with the previous embodiment, of the hot and cold water supply pipes. The overflow member I20 is disposed beneath the rim of the tub, and in line with the faucet fixture II8.

If the tub is a right end connected tub, the opening III will be used for the faucet fixture connection, while if for a left hand connected tub, the opening III will be employed, as shown in Figure 5. When a left hand connected tub is employed, the opening III' may be covered by an ornamental fitting, such as a soap dish I22 or the like.

The rim H3 is provided with two sets of openings, indicated generally by reference numerals I23 and I24. These openings correspond to the opening 29' and the bolt openings for the bolts 24 as shown in Figure 6, to provide for connection of the hot and cold water supply pipes to the lavatory faucet fixture 28, and to provide threaded openings for receiving the supporting bolts 24. However, when the lavatory is positioned over the openings I23, the openings I24 would ordinarily be exposed.

In order to enhance the appearance of the tub, I have provided, as shown in Figures 9 and 10, means for covering these openings, comprising the ornamental fitting I25, which is provided with supporting bolt members I26 secured in the two outside openings of the set of openings I23, and with a central dummy member I21 covering the central one of the set of openings. The member I25 may be provided with bumpers I23, adapted to engage the rear surface of the watercloset seat cover 55 when the same is raised in position, since the water-closet will be positioned in alignment with the unused set of openings I23 or I24.

In the front face or wall of the tub I provide two sets of spaced openings, comprising main openings I30 and I30, flush valve openings I32 and I32, drain or waste openings for the lavatory indicated at I33 and I33, and supporting threaded bolt openings I34 and I34 so that when the lavatory and water closet are disposed in the manner shown in Figure 9, the waste opening from the bowl 50' of the water-closet will extend through opening I30, by means of an outlet member such as member 60, to be connected by means of elbow 58 to the waste pipe communicating with the main waste pipe 81. Similarly, the threaded openings I34 will receive the supporting bolts I 40, as shown in Figure 9, the bracket portion of the water-closet in this instance being made of greater lateral extent than the bracket 52 of Figure 1, in order to provide alarger bearing and supporting surface therefor. The opening I32 in this particular embodiment will then receive a flush valve such as the valve 51, and the opening I33 will provide an inlet for the flushing water to the water-closet.

Similarly, the opening I30 will be covered by the lower end of the bracket or pedestal I8 of the lavatory I6, the opening I33 will receive the drain pipe 40 and elbow 42, the openings I34 will receive the attaching bolts 20 and the opening I32 will receive an ornamental closure fitting I42. If the lavatory I6 and the water-closet 50 are reversed, the connections will be correspondingly reversed as is apparent from the drawings. By the provision of the two sets of openings in the front wall IIB, the two sets of openings in the rim II3, comprising the openings I23 and I24, and the two end openings III and III the tub is adapted either for right or left hand connection, and also, is adapted to support the watercloset and lavatory in either of the two positions, depending upon which end the water connections are provided. The tub H2 is provided with a drain I43 extending through an opening in the supporting web I I I, and connected at the base of the overflow stand pipe I23.

From the above description, it will be apparent that I have provided a bathroom ensemble which does not obstruct either the walls or floor of the bathroom, and in which all of the piping connections and waste connections are concealed from view. Further, I provide a construction which is adapted for use either with right 01- -left hand water supply connections, and which may be selectively changed to suit the particular application for which the tub is employed. Further, by the provision of the longitudinally extending dovetail grooves 64, and by reason of the oppositely threaded ends of the waste pipes 53 and 93, the roughing in operations are considerably reduced, and the space necessary for such operations is correspondingly reduced.

By the elimination of the unsightly and unsanitary piping connections, as well as the elimination of the floor supports for the lavatory and water-closet, I am able to provide a compact, neat appearing and sanitary type of bathroom plumbing fixture or ensemble, which is so capable of being maintained clean and sanitary, and in which the cleaning is facilitated by the elimination of the obstructions on the floors and walls and around the piping connections.

It is obvious that changes, both in the design and construction of the present invention may be provided, without, however, departing from the underlying basic features thereof, and I do not intend to be limited to the exact construction disclosed and described, except as defined 0 by the scope and spirit of the appended claims.
