15 Claims. (01. 20-2) The present invention relates in general to building construction, and the object of the invention is to provide a utility unit comprising a heating plant and the necessary items of equipment for furnishing the kitchen and bathroom of a dwelling house or apartment. The unit preferably includes also the essential laundry equipment, such as clothes washer and laundry tubs.

The assembly of these various items of equipment into a single unit, which can be to a considerable extent prefabricated, not only speeds up the construction work, but also substantially reduces the cost thereof, and makes it possible to erect small or moderate sized houses in .a minimum of time and at less expense than .has been possible heretofore.

Prefabricated unitary building structures have been proposed before, and houses have been built or proposed to be built in sections, each section being a prefabricated room. In constructing such a house the foundation is laid, the rooms are scribed in the foregoing have the disadvantage that the rooms are necessarily rather small, as

even reasonably large rooms would be too heavy and cumbrous to handle. Acomplete bathroom, as to which the small size is not so objectionable, has the added weight of the various equipment items and'is as heavy as a much larger ordinary room. For these and other reasons which need not be gone into the use of complete prefabricated rooms in the construction of houses is .not very practicable.

In carrying .out the present invention the use of prefabricated rooms has been abandoned. The utility unit which is the subject of the invention is not a room, but is a structure around which .a

number of rooms are built and which forms part of such rooms and acts as a partition betweenv them; The various equipment items are solocated in the unit that when the building iscompleted each piece of equipment will be in the appropriateroom. h

The invention and various features thereof will be described more fully in the detailed .specifica-i tion which follows, reference being had to the accompanying drawings, in which-,-.

Figs. 1 and 2 show typical floor plansfor indicated at '21.

Referring to Fig. l, the fioor plan shown will be briefly described. The reference character Ill indicates the front entrance, opening into the living room I I. Front and rear bedrooms are indicated at I2 and I3, respectively. The kitchen is indicated at M and has a side door I1. The reference character [6 indicates the bathroom, while 15 indicates the laundry, also serving as a hallway between kitchen and bathroom. The utility unit is indicated by refernce character l8 and is associated with the kitchen, bathroom and laundry, which are built around the unit onthree sides. The unit'forms the partition 'between'the kitchen and bathroom and includes all the equipment items required for these rooms properly located in the unit so that each item is available for use in theapprcpriate room. The laundry is continuous with the kitchen but is disposed at right angles thereto and has available for use certain equipment items located at the endo'f the utility unit.

Fig. '2 shows a somewhat different floor plan, illustrating the flexibility in the design of buildings in which the utility unit is incorporated. The'livin-g room is indicated at 20 and has the front entrance 2!. Bedrooms are indicated at 22 and 23. The-utility unit is indicated at! 8, and forms the partition between kitchen 24 and the bathroom 25. The reference character 26 indicates a'jgeneral utility room, which could be used as a dining room if desired: The rear .door is It will be observed that in this layout the utility unit 'i's'located against .an inside partition rather than against an outer wall a dish washing machine.

Proceeding now to the bathroom on the opposite side of the unit, a water closet, lavatory and bathtub are indicated by reference numerals 36,

3? and 38, respectively. A medicine case with 40 is another ing in which an electrical distribution panel is located. Linen shelves or cabinets are indicated at ii. A glass door 42 partitions off part of the space above the bath tub to form a shower compartment.

At the end of the unit are the laundry items, consisting of a clothes washer 43 and laundry tubs 44 and 45. A storage case or cabinet is indicated at 4'6.

The equipment described, with the exception of the cabinets and cases located near the ceiling, are shown'in their proper relative location in Fig. 9, which will assist in a clear understanding of the arrangement. Fig. 9 also shows the central compartment 48 in which the heating plant and plumbing connections for the equipment items are located.

It will be understood that the invention is not limited to the particular selection and arrangement of equipment which is shown and described. The items mentioned, however, are the .ones usually required and the drawings are believed to show an excellent arrangement thereof.

The construction of the utility unit may now be considered more in detail.

Referring to Figs. '7 and 8, the central compartment 48 which houses the heating plant and other mechanical equipment, is built upon a substantial base comprising end channels 50 and 60 panel 5'! rests on the plate 53 to which it is secured in a similar manner. The other end panel 58 does not extend down to the base but only as far as the top of the bath tub, thus providing an opening for the drain and overflow pipes. The side and end panels are suitably joined together along their contacting edges and form the compartment 48, hereinbefore referred to. The height of this compartment is about eight inches or so short of the ceiling height.

The construction of the panels is not important. They may be made of spaced metal sheets, for example, as indicated in the drawing, and may be given increased strength and rigidity by vertical channels such as 59 and 60.

The compartment 48 contains the heating The plant itself forms no part of the invention and consequently the details are not shown. It is "assumed, however, that gas is used as fuel, although an oil burning plant could be used.

flhe casing 6! may be supported on channels 62 "and'tB extending across the compartment and secured at the ends to the vertical channel 60 on side panel 55 and to acorresponding channel "on the side panel 58. The casing 6| may be anchored to the end panel 51 near the top by means of angle members 64 and 65.

Also contained in the compartment 48 is the water heater 86, which is supported on the pedestal 61, which in turn rests on the I beam -68. This beam is part of the base and extends between the two side channels such as 52, to which it is suitably secured.

In addition to the foregoing the compartment 48 contains the plumbing which is required to connect up the heating plant, water heater, and the other equipment items heretofore described. The arrangement of the various pipes will be explained briefly. The reference character 10 indicates the soil pipe, which extends vertically upward from bottom to top of the compartment. At the top the pipe is threaded for attachment of an extension for projection through the roof. At the bottom the soil pipe preferably terminates in a coupling, providing for attachment of an extension to the sewer.

The various equipments from which waste water has to be disposed of all drain into the soil pipe 10. The bath tub 38 is drained by way of the trap H and pipe 12. The reference character 1'5 indicates a horizontal pipe which extends from vertical pipe 13 through the side panel 56 to connect with the drain from the lavatory 31. No drain for the water closet is provided, as this drain has to go through the floor. It is installed on the job and connects to the soil pipe extension which goes to the sewer. The sink'32 and dish Washer 33 are drained by pipes 16 and H, respectively, which empty into the pipe 18. These pipes are indicated in dotted lines in Fig. 7, as is also the pipe 19 for draining the laundry tubs 44 and 45. The latter pipe is shown also in Fig. 8. Pipe is for chaining the clothes washer 43. Pipe 14 is a vent pipe.

' The soil pipe 10 and the large connecting pipes such as 12, 13, '14 and 18 are supported in the compartment ina suitable manner. The weight of the pipes is taken mainly on the I beam 68 and on a channel 8| which extends across the base parallel thereto. At the top the soil pipe may be secured to the casing 6| for the heating plant as indicated. Further support is af- 1 forded by the various drains where they pass through the side and end panels of the compartment. It will be understood also that temporary blocking and lashing may be employed 'to=--preclude'-'any chance of the pipes becoming loose or disarrangedpriorto installation of the as e y The main gas pipe is indicated at 82- -andis threaded for connection to the gas supply line; A shut off valve is indicated at 83-. The gas pipe 82 has a branch 84 extending to the stove 3! and two branches 85 and 86 which extend to the water heater 66, and to the heating plant,

respectively.

The main water pipe is indicated at 81 and extends vertically upward to the water heater 66.-- A shut ofi valve'is indicated at 88. --The reference characters 90- and '91-. indicate hot and cold water pipes, respectively, which extend along the side panel 56- and the endpanel 51 to supply hot and coldwater to the bath tub, shower, lavatory and'other equipment-items which require water. The hot-water pipe 9!! is connected to the water heater by a pipe 89, while the cold water pipe 91 is connected to the main water pipe 81 by a pipe 92. The connections to the various pieces of equipment are indicated in the drawings and need not be explained in detail. 5 V

The central compartment 48 together withthe base or frame on which it rests and the equipment inside may be referred to as a mechanical section. It is prefabricated, with heatingv plant and water heater installed as described, and plumbing connections brought through the panels or walls of the compartment to the outside.

In the manufacture of the mechanicalzsection,

the end panel 58 is preferably assembled last, so as to afford ready access to the interior of the compartment for the installation of the heating plant, water heater and plumbing. After the panel 58 is assembled to complete the com.- partment access to the interior thereof is had through the door 94.

The wall panel 95, which cooperates with panel 55 to form one wall of the kitchen, .rests on the frame and may be assembled as part of the mechanical section. The wall panel 96, which forms part of the bathroom wall, is not assembled to the mechanical section until after the latter has been installed. This is true also of the end panel 97. The end panel goes against a wall or partition of the building and need not be finished on the outside. The door 42 may be assembled on the end panel by suitable hinges and is fastened back against the panel by a suitable catch. The wall panel 96 is L shaped, and on this account may be made in two sections, if desired, so that it can be shipped'flat.

The panel 56, which forms part of the bathroom wall, is equippedcomplete with medicine cabinet 39, distribution box 40, towel racks, etc. I at the time the mechanical unitis manufactured. Ihe lavatory 31 and water closet 36 are not as-' .sembled, however, until the unit is installed.

These two pieces of equipment may be standard stock items. The bath tub, which is also assembled after the mechanical unit is installed,

is preferably of special construction to fit the unit, although a stock tub could beused.

The electrical wiring is not shown, butit will beiunderstood that the mechanical unit is pref- .erably wired to the distribution. panel soa's. to

The refrigerator is spaced away from the wall enough to allow a circulation of air. The kitchen section comprising the stove and other items is installed against the wall panel 55 along; side the refrigerator and is supported on a sub; base 34. The plumbing connections for the kitchen unit appear at the proper location on the outside of wall 55 so that the connections can-be completed in a minimum of time.

The laundry section is installed at the end ,of the mechanical section and rests on a sub-base like the kitchen section. Plumbing connections for the laundry section have also been provided. In the bathroom the lavatory 31 is installedon the wall panel 56 in the usualmanner and is connected to the hot and cold water pipes and drain pipe which preferably extend through-the wall panel for this purpose. A pipe forthe tank of the water closet is also provided. The drain, however, goes through the floor and is connected to the soil pipe in the basement, as previously mentioned. The bathtub is slid into position from the bathroomand is supported partlyon the base of the mechanical section, as shown, in Fig. 8, and partly by a depending skirt which reaches to the iioor as shown in Fig. 5. ,The bath tub is connected up from inside the compartment 48 of the mechanical section,-access to which is had by way of the door 94. To reach the door the Workman has to step into the bath tub. but this is no particular objection. The bottomof the opening for door 94. should be several' inches higher than the rim of the bath tub, and the door should be sealed bygaskets so as to avoid any danger of moisture entering the compartment 48.

. The, rear portion of the bath tub may be used as a shower and can be closed offby the. glass door 42 to prevent water splashing on the floor outside the tub. Catches are provided sothat the door 42 can be secured in open or closed position. The fittings for hot and cold water and the shower head are mounted on the endwall panel 58 of the compartment 48, and preferably are installed during manufacture ofthe'mechanical section. A shower arrangement constitutes the shelf section 4| is secured to the wall panel 56 and'to the end panel 91.

Small'bolts may be used, for example. The tops of these sections are flush with the top of the panels. The lower side of the shelf section 4| maybe regarded as part of the ceiling of the bathroom. This ceiling is completed above the shower compartment by means of a ceiling panel I Ill, shown'in Fig. 6.

After the cabinetand shelf sections have been assembled, the hot air ducts Ill, ll2 and H3 maybe installed, as shown inFig. 6. These air ductsconnect with a hot air chamber in casing SI of the heating plant and ducts II I and I 12 extend to the kitchen and bathroom, respectively,

opening into these rooms near the ceiling. Air

The utility unit is completed by adding the trim panels H5, H6 and Ill, which are secured to the cabinet and shelf sections and close the space between these sections and the finished ceiling. The trim panels are provided with openings for the air ducts as shown. H

While the invention is intended mainly for use in the construction of new houses, it may also be used in the renovation or modernization of old houses, since the mechanical section and other sections appurtenant thereto are of reasonable dimensions, being narrow enough to go through an ordinary door. In this field, as in the new building field, the utility unit is adapted to replace the separate heating, kitchen, bathroom and laundry installations which have been provided heretofore and furnish the same facilities in a more convenient form and at a greatly reduced cost. The invention makes it possible, therefore, for the small home owner to have not only the strictly essential equipment, but to enjoy also certain equipment usually considered to fall in the luxury class and whichv he otherwise might not be able to afford.

A specific embodyment of the invention has been shown and described but it will be understood that this has been done for the sake of clarity and to facilitate the description. Modifications may be made, and I do not therefore wish to be restricted to the exact disclosure herein, but desire to include and have protected by Letters Patent all forms and modifications of the invention which come within the scope of the appended claims.
