Filed Oct. 6, 1927' 2 Sheets-Sheet 2 Patented June 10, 1 930 UNITED STATES OWEN n. AYERS AND cnnnLEs MoBLnY, or DAYTON, OHIO BATHROOM EQUIPMENT Application filed October 6, 1927. Serial No. 224,395.

Our invention relates to bathroom equipment, and more particularly to a unitary structure embodying a bath tub, a lavatory stand, and water closet or commode with the necessary plumbing connections contained and concealed within the unit to facilitate installation with single supply and drain connections. c p

-Ordinarily bath room equipment consists 1 of separate structures independently installed, whereby each unit must have its own drain and supply connection. This necessarily complicates the plumbing system and involves needless excessive expense and labor for installation. ,Moreover, the care and attention necessary to keep such plumbing connections in proper condition is materially increased. A

While we are aware that heretofore at tempts have been made to combine bathroom units into a singleunitary structure, the arrangement and connections have been more or less unsatisfactory and inconvenient and particularly have not been in accordance with the standard plumbing code requirements.

The object of the invention is to simplify the structure, as well-as the means and mode of installation of such unitary bathroom equipment, whereby it will not only be more eflicient in use but is capable of being more easily and quickly installed with minimum expense and labor operations, durable, compact and unlikely to get out of repair. v

which is enclosed an independent detachable bowl, which for economy of manufacture may be an enameled metal bowl or one of analogous character.

With the above primary and other'incidental objects in view, as will more fully appear in the specification, the invention consists in the features of construction, the parts and combinations thereof, and the mode of. assembly and installation, or their equivalents, as hereinafter described and set forth in the claims.

shown the preferred, but obviously not necessarily the only form of embodiment of the in'- 1 vention, Fig. 1 is a perspective view of the unitary bathroom equipment structure forming the subject matter hereof. Fig. 2 is a rear elevation thereof showing the system of plumbing connections. Fig. 3 is a vertical sectional view through the water closet se'ction of the structure. 5 Fig. 4; is a perspective view of the modification of the unit wherein the tub and the lavatoryand closet are arranged in right angle relation to enable the unitarystructure to be installed in a corner of the bathroom. Fig. 5 is a bottom plan view of the closet seat. Fig. 6 is a detail view of a conventional type of cast iron toilet bowl applied to seat or housing structure of the. present installation.

Like parts are indicated byf'similar characters of reference throughout the several views.

Referring to the drawings, 1 indicates the bath tub section of the unitary equipment structure of which 2 is the lavatory or wash stand and 3 the toilet or closet'secticn. These several parts are formed as an integral unit either from porcelain or porcelain coated or enameled metal ware, as is customer with equipment of this character. While e several sections have been shown in Fig. 1 arranged in lineal succession to accommodate the equipment to bathrooms of small dimensions and adapt it for corner installation, the several sections have been shown in Fig. 4 arranged in 'an angular succession. It will be understood that the unit whether straight or of angle formation will be made in both right and left hand assemblies, that is to say,

in order to meet different conditions o f'int co In the accompanying. drawing, wherein is sides of the lavatory stands,

- at the factory or at the plumbing shop before taking the unit tothe place of installation. It then remains to connect the supply and drain couplings, whichare accessible through a suitable opening in thc'bathroom Wall as is usually provided. The water closet or commode comprises a seat having a vertical front and flat top forming therebeneath a compartment in which is located the closet bowl 6. This bowl 6 is formed independent of the seat or bathroom unit. Inasmuch as the bowl is entirely concealed within the seat section 3 it maybe of enameled metalware and hence less expensive than the usual all porcelain bowl. The flush ring 7 for the closet bowl 6 is formed integral with the top of the seat section 3 and is connected through a passage or conduit 7 formed in the structural unit beneath the top of the seat 3 with the flush tank 8. This flush tank is located at the rear of the seat 3 and comprises a portion of the unitary structure.

The closet bowl 6 isconnected at 9 with a soil pipe couplin 10 to the lower end of which is preferab y, though not necessarily,

connected a drainage elbow which will permit a limited degree of adjustmentof the unit relative to the outlet conduit. The upper end of the hub 10 is adapted to receive the vent pipe shown by dotted lines at 11 which is preferabliy connected with the coupling 10 let of thetub.

by a fortye degree elbow, thus permitting the vent pipe 11 to be extended upwardly through the wall of the-bathroom back of the unit. Leading from the bathtub 1 is a conduit 12 communicatin with the main outlet in the bottom of the tu and having a branch conduit 13 leadin from the overflow outjoined by a vertical drain conduit 14 leading from the overflow and drain of the lavatory bowl 5. Intermediate the coupling- 10 and the juncture of the drain conduit 13 and 14 with the conduit 12, the latter is provided with the customary trap 15. Thus t e drainage conduit from the several sections of the a branch conduit .17 leading to the tub 1. A corresponding coldwater conduit 18 also drain conduit 12 isflush tank 8 of the water closet section.

ose to the front of the unit.-

1 unitary structure lead to the outlet coupling,

parent that there'is thus pro leads upwardly to the wash bowl 5 and is provided not only with a lateral conduit 19 leading to the tub 1, but also a second lateral branch conduit 20 which supplies ize 3 providing elbow fittings on the lower ends of the hot and cold water supply conduits l6 and 18 a limited degree of adjustment is possible to enable the convenient connection of these conduits with the hot and cold water supply lines.

The opening from the flush rim supply passage to the interior of the flush tank 8 is adapted to receive the usual screw-threaded bushing with which is connected the valve seat for the flush valve of the closet. The" closet bowl is preferably provided with attachment lugs by which it may be bolted or otherwise secured to the underside of the top ortion of the seat 3, the margin of the bow being cemented or sealed with a packing of'putty or similar material. On top seat 3 1s provided the usual seat rim 22 of wood or composition, to which is hinged the usual lid 23., To provide suitable support and to enable theunit to be embedded or set into the wall of a bathroom the base margin of the unit is provided withan inturned flange 24 while the vertical margins 25 are proJected rearwardly for embedment in the bathroom wall and the top margin of the tub I is provided with a rear marginal upof' the standing flange 25 which, when embedded Such construction, however, is notessential and such top may be formed integral with the remainder of the unit.

. The construction is such that the plumbin connections may be assembled as standar units interchangeable with different ment assemblies, not only of the same style but of reverse type, angular or lineal, as the case may be. Such standardization of the plumbing connections greatly minimizes cost and facilitates installation. 7

' From the above.description it will be apvided a construction of the character described, possessing the particular features of advantage before enumerated as desirable, viouslyis susceptible of modification in its form, proportions, without'departing from the princip einvolved or sacrificing any of its advanta es.

Whilein'order to comply with the statute the invention is described in languagefmore or less specific as to'structural features it is to be understood that the invention isnot but which oband arrangement of arts,
