Part 8
Moreover, the lighting of a small house must be studied with common sense, and no rule of the thumb can be laid down. Certain enthusiastic illuminating engineers offer typical plans and suggestions for the wiring of houses, which plans are crowded so full of outlets that they look like a map of the starry heavens. We have in front of us now such a plan in which a small living-room is marked to contain four wall outlets containing two lights each, two more outlets on each side of the fireplace, a wall plug for attaching a portable lamp or two lights, and a central ceiling outlet for four lights. In addition to these is another base plug and floor plug. The room is about 14 by 17 feet, and if all lights were turned on at once and all base plugs attached to lamps there would be a possible grand total of twenty 50-watt lamps in this medium-sized room. Such brilliant illumination might please the jaded nerves of the tired business man, but his wife would never consent to such a garish display of wealth-eating current.
The problem of illumination for the small house can be sanely considered from five different angles: (1) General illumination; (2) local illumination; (3) ornamental illumination; (4) movable lamps; and (5) light control.
By general illumination is meant the lighting required to flood the room as a whole, and not locally in any one corner. The easiest and commonest method of doing this is to provide a central fixture, containing from two to four 50-watt lamps, or their equivalent, which are hidden in some commercial type of semi-indirect lighting fixture. The type of fixture shown on page 122 is one of the finest, and with a silk shade around it the warm, cheerful effect of a home is greatly enhanced by this method of lighting. When this fixture is hung in the dining-room or living-room a single 200-watt Mazda lamp is employed, while in the other rooms a single 100-watt lamp is used. In the kitchen no shade is necessary. Usually in laying out the electric outlets upon a plan the central dining-room and living-room lights are shown to carry four 50-watt lamps, and those in the other rooms, in the hall, and on the porch are marked to have two 50-watt lamps or their equivalent.
But it is not absolutely essential to have a central light for general illumination. Some architects prefer to have a certain number of wall lights controlled by one switch, and obtain a general glow with these lamps. By securing the right type of fixture which shields the raw filament of light from the eyes, this method of general illumination often produces a feeling of comfort and homelikeness unsurpassed by the other system.
In those rooms where work is done under the central light, such as the kitchen and pantry, and where opaque, indirect reflectors have been used throughout the rest of the house, it is essential to provide direct lighting-fixtures, so that the light can be thrown down upon the working plane. Translucent reflectors or prismatic reflectors are used, and a frosted bulb or a porcelain-tipped bulb is most suitable with this reflector.
Local illumination is intended to give greater intensity of light over certain portions of the room where work is carried on. Either a wall light or a special drop light, protected by a reflector, is used. Such lights are placed conveniently over the kitchen-sink and side table, over the laundry-tubs and ironing-board, over the coal-bin, near the boiler and over the work-bench in the cellar, by the side of the lavatory in the bathroom, over at the side of the dresser in the bedrooms, inside of closets and alongside of the serving-table in the dining-room. These local outlets are generally planned to carry two 50-watt lamps or their equivalent.
Other wall lights than these are usually introduced for ornamental purposes. The side lights for the fireplace in the living-room, or the panel lights on the wall, or the bracket lights for the bookcase cannot be considered more than ornamental features. Not more than one 50-watt lamp is planned for these outlets.
In addition to the general, local, and ornamental illumination are those portable lamps which have become more and more a serviceable and decorative feature of the home. The reading-lamp in the living-room, the light for the music on the piano, the table-lamp in the bedroom, and the candle-lamps on the dining-room table are the most used of this portable type. To properly attach these bulbs, a base-board outlet must be installed at a convenient place in the room, so that the electric cord to the light will not have to be too long nor pass across any part of the floor where it may trip up the feet of some absent-minded member of the family.
When the lighting of the small house has been considered from these angles, the control is then the essential problem. The incoming feeder, the meter, the house switch and service switch, and the distributing panel must be located conveniently in the cellar. Often the distributing panel with its fuses is placed on the first floor for convenience of replacing a burned out fuse when some line has been overcharged.
The next matter of control is the location of switches. All central outlets and general illumination should be controlled by a switch at the entrance-door to the room. The usual type of switch used is the so-called three-way switch.
The hall light should be controlled from up-stairs and from down-stairs. The porch lights and the front and rear door lights should be switched on and off either from the inside or outside of the house. One light in the cellar should be governed by a switch at the top of the cellar stairs. And this is about all the complication of control necessary.
Now, in addition to the lighting of a house, certain floor and base-board outlets must be provided for attaching various electrical devices that have become rather common. In every cellar there should be at least one special power-current outlet for any household machinery that might be installed. In the laundry there should be at least two special outlets to which a washing-machine, a mangle, electric drier, or an electric iron can be connected.
There should be at least one special outlet in the kitchen to which may be attached a motor for operating the coffee-grinder, egg-beater, ice-cream freezer, dish-washer, etc. Sometimes an electric refrigerator may be installed, in which case an outlet must be provided for this motor.
Sometimes a special outlet is installed in pantry for a dish-warmer or water-heater.
In the dining-room a floor outlet should be provided for operating on the table such things as a toaster, chafing-dish, coffee-percolator, egg-boiler, etc.
In the living-room a floor outlet will be found useful for such electric apparatus as would be carried on a tea-table or for running a home stereopticon.
In the bathroom and in the master’s bedroom a special outlet is useful to connect up such devices as vibrators, hair-driers, curling-irons, shaving-mugs, electric heaters, etc.
Base-board outlets of the ordinary type should be distributed throughout the house to provide convenient connections for vacuum cleaners and fans.
Most of these electric devices require not more than 600 watts. Electric irons, toasters, chafing-dishes, coffee-percolators, and other heating mechanisms use up to this maximum of watts, but motor-operated machines, like fans and ice-cream freezers, require about 100 watts.
As to the kind of wiring which the architect should specify, he has a limited choice. The knob-and-tube system is the cheapest, but not the safest. The flexible cable (BX) is better, although slightly more expensive. Rigid conduits or flexible steel conduits are not suited to the economic needs of the small house and are not used, except in special places. For example, an overhead feed wire may be brought in from the street at the level of the cornice, and then carried down to the cellar in a rigid conduit on the outside of the house.
In addition to the wiring for lighting there must be an independent system for bell service. The current for such a system must be supplied by dry batteries when the local power company gives a service of direct current, but when it supplies an alternating current a transformer can be used and the bells operated upon this energy. In the kitchen there should be a magnet-operated annunciator, connected with the front and rear doors and the dining-room push-button.
In laying out the lighting plans for a small house the standard symbols shown here are used, but a key should always be given to their meaning upon some part of the sheet, for it must be appreciated that the contractor can easily forget.
As an aid to laying out the lighting system on the plans, the following checking list is suggested, since it is simple.
Unless specified to the contrary, it is usual to assume that wall outlets in the living-room are to be placed 5 feet 6 inches above the floor, in bedrooms 5 feet 4 inches, and in halls 6 feet 3 inches. The usual height at which switches are placed is 4 feet.
Thus, by using common sense and the phrase in the specifications, “All work shall meet the requirements of the National Electric Code,” and requiring the contractor to furnish a certificate of approval for the entire installation as issued by the Board of Fire Underwriters having jurisdiction in the community, the architect has a reasonable surety of securing a good and safe system of wiring and lighting.
XI CONSTRUCTION OF THE TRIM
The wood trim, the doors and windows, and the built-in furniture of the small house can make or mar its appearance more than any other one factor. Indeed, in no other form of architecture is the study of these details more important, and yet in no other type of building is the limitation of cost more exactingly imposed upon the architectural treatment of the trim.
By the very economy demanded in the small house, the architect must make the mouldings of his casing in the simplest possible forms. The trim around doors and windows on the exterior and interior can boast of no special mouldings. In fact the selection must be made from stock material or else the cost will be too great. Most planing mills have standard types of trim, but generally they are very badly designed. However, one cannot go wrong in using a plain board casing ¾ inch by 3⅝ inches, which has slightly rounded corners. The tops of doors and windows which have this simple casing should be capped with a fillet ⁷/₁₆ inch, a head casing ¾ inch by 5 inches, and a cap mould 1⅛ inches by 2 inches. This eliminates the mitred corner, which is of such doubtful value in cheap work, since most wood trim is not properly seasoned and will quickly open all mitred joints.
To match this simple trim the window apron should be a plain board ¾ inch by 3⅝ inches, and the stool 1⅛ inches by 3⅝ inches. A plinth block at the base of the door trim in size 1⅛ inches by 3¾ inches by 7¼ inches will match up with a plain base-board, ¾ inch by 7¼ inches, or one of similar size, with a cyma recta moulding on top.
If the local mill from which the trim is purchased has stock mouldings of pleasing design, the architect may safely specify them, but he should not make the economic mistake of demanding specially designed casing from full-size details of his own. The small house cannot stand this additional cost.
In selecting the trim, it is always important to bear in mind that it must harmonize with the walls and have no obtrusive appearance, since it acts with the walls as a background for the furniture. In Colonial work the painting of the trim white, pearl-gray, or cream is always the most pleasing, and so the architect should select a wood which will best take the paint. White wood and white pine are ideal for this purpose. Gum wood is good, but there is always the chance that it will not hold its place and twist. Yellow pine is difficult to paint well, since the hard summer wood has a tendency to stand out beyond the softer spring wood, making the surface irregular; but this difficulty can be overcome if a number of priming coats are used to fill in the grain before the enamel is applied. It is a mistake to finish the painted trim with a glossy enamel, for this will destroy its quietness and background effect. A matte surface of paint or an egg-shell enamel finish is better.
This same principle should be followed in selecting and treating the hardwood casing which is not to be painted. The trim should never be finished with a bright, glossy varnish and stain, for nothing is more ugly in its final effect. Treat the hardwood trim, such as oak, chestnut, ash, and the like, with an oil stain; rub in a filler, stained slightly darker, and then shellac. Over this apply a wax finish, and rub this down with a shoe brush. Varnish manufacturers make grades of varnish which give the dull effect of wax, and these can be used, if desired; but why? Many prefer to even omit the shellac and depend entirely upon the wax for the gloss.
When trim is delivered to the job, it should not be stored in a damp place nor fitted in place before the plaster is entirely dry. In fact, in order to protect the trim from losing its shape, as soon as it comes on the job a priming coat, or filler, should be applied to it, and the ends and back painted with white-lead and oil. It will be noticed that all well-designed trim has a gouged-out space at the back to permit circulation of air around it, and also to make it easier to fit against a flat surface of plaster.
Mouldings for the trim of exterior cornices, string-courses, and the like are often specially designed by architects for the small house, but it is a much better plan to use stock mouldings, selecting them to approximate the design that is desired. Through the efforts of many concerns the market affords many well-designed stock patterns of mouldings for exterior purposes. The idea is sound, and makes possible a great variety of designs through the standardization of parts, but at the same time cutting down the cost.
Likewise the standardization of doors and windows is another economic aid for the small house.
As a rule, all exterior doors should be at least 1¾ inches thick, and of white pine, painted. The veneered door is not a very satisfactory type for outside use, unless, perhaps, it is protected by the porch, for even with the best waterproof glue there is a considerable tendency on the part of the veneer to break away from the soft pine core. Some consider that the 1⅜-inch-thick door is satisfactory for exterior doors in the small house, but, generally speaking, it is best to use this thickness only for interior doors.
Softwood doors, 1¾ inches thick, have panels, if they are raised, only 1⅛ inches thick; while doors 1⅜ inches thick have raised panels only ⁹/₁₆ inch thick, and flat panels ⁵/₁₆ inch thick. The latter is quite evidently too thin for exterior doors.
Interior doors of veneered woods usually have flat panels, ⁵/₁₆ inch thick, except the one-panel door, which is as thick as ⁷/₁₆ inch. Such panels consist of three layers, the two outside veneers and the interior softwood core with the grain running at right angles to the veneer. The stiles and rails of well-built veneered doors are made of built-up pine blocks, glued and locked together, with a tongue-and-groove joint, and fastened at the corners with hardwood dowels. Strips of hardwood to match the veneered face should be placed on each edge of the stiles and rails.
The common-stock sizes of doors are as follows:
2 feet by 6 feet. 2 feet by 6 feet 6 inches. 2 feet by 6 feet 8 inches. 2 feet 4 inches by 6 feet 6 inches. 2 feet 4 inches by 6 feet 8 inches. 2 feet 6 inches by 6 feet 6 inches. 2 feet 6 inches by 6 feet 8 inches. 2 feet 6 inches by 7 feet. 3 feet by 6 feet 8 inches. 2 feet 8 inches by 7 feet. 3 feet by 6 feet 8 inches. 3 feet by 7 feet.
The commonest type of window for the small house is equipped with the double-hung sash. This sash should be made of 1⅛-inch white pine, mortised and tenoned at the corners. The meeting rail ought to be rabbeted so that water is prevented from seeping through, and the bottom rail ought also to be rabbeted to fit over a similar rabbet in the sill. The size of the lower rail is usually 3 inches wide, the sides and top rails 2 inches wide, and the meeting rail 1⅛ inches wide. It is generally admitted that a window has little architectural charm without muntins, and these are made ¾ inch wide, as a rule. The glass of the window is inserted into the sash frame at least ¼ inch, and its plane is about one-third in from the outside face of the rails. The over-all dimensions of a window sash are determined by the size glass used, and as glass is cut in inches, the over-all dimensions of a sash will be in fraction of inches. For example, a double-hung sash of twelve lights, each 8 inches by 10 inches, will give a sash opening of 2 feet 4½ inches by 3 feet. If the lights measure 9 inches by 12 inches, then the sash size will be 2 feet 7½ inches by 4 feet 6 inches.
The best type of double-hung window-frame is constructed so that the blind stop is rabbeted to receive the pulley stile, preventing any wind from blowing through. The pulley stiles are usually made of yellow pine, but the outside casing and sills should be of white pine. It is also a good precaution to have the sill rabbeted to receive the ground strip, so that air cannot come underneath the sill. The use of 1³/₁₆ inch-thick material is common for all parts of the frame except the sill, which ought to be 1¾ inches thick. A 2¼-inch depth should be allowed for the weights in the box, and a space of ⅞ inch left between the stud and the top of the frame. Parting strips are made ⅜ inch wide.
Where the frame is to be built into a masonry wall, the back of the weight-box is closed in, and a moulding, called the brick mould, should be provided for covering the outside joint between frame and masonry. In order to make this joint tight in hollow-tile construction, it is essential to stuff the back of the brick mould with elastic roofing cement.
There is not much reason to rehearse here the pros and cons of the casement window. When such windows open in, the screens and blinds are easier to handle, but the weather is apt to leak in more. When the sash opens out, screening is difficult, unless some patent operating hardware is used, but the window is more weatherproof. In either case, the difficulty of weathering can be overcome to a large extent by not attempting to keep out the rain, but lead it down and around the sides, draining it off at the sill. This is accomplished by cutting a ¼-inch half-round groove around the sides and in the sill to act as a canal for collecting the water which has seeped in. A few ¼-inch round weep-holes from the groove in this sill outward will drain this collection of water off. Casement frames are made of heavier material than those used for double-hung sash, 1¾ inches being common. As the sash is hung from the sides like a door, its weight must not be so great that it will cause it to sag, and for this reason it is customary to limit the width of sash to 2 feet maximum. Some designers believe that the sash should also be at least 1¾ inches thick.
Although blinds add to the cost of the small house without apparently adding practical value, yet they are one of the most useful mediums of securing variation of color on the elevations. In Colonial days shutters served to protect the house, and were made solid with only a small hole in them, generally of some ornate cut-out design, like a half-moon, flower-pot, etc. To-day we want slats for ventilation. A good compromise, then, is to make the lower part of slats and the upper part solid, with a cut-out design. The stiles and rails of the shutter are made of 1⅛-inch material, the bottom rail being 3½ inches wide, the stiles and top rails 2 inches wide. Intermediate rails are often made 2½ inches wide. It is best to project the stile 1 inch below the bottom of the lower rail, so that water collecting on the sill can drain off underneath the blind.
In addition to the blinds, the window should be equipped with screens. These should be of copper, for only this material is economical in the long run. They are usually made of ¾-inch material, and the lower rail, stiles, and top rail made 1¾ inches wide.
Other mill work of the exterior, such as porch columns, rails, etc., ought to be built up from stock mouldings and patterns. There are numerous concerns selling well-designed wooden columns. The great danger of using stock columns, however, is in the fitting. Certain stock lengths are made with well-planned entasis, but if the design calls for an intermediate length the column is cut short, which destroys its proportions. On this basis many select square columns, or thin wooden columns without much entasis. The illustrations show some common-stock sizes for other outside trim, such as lattice, top rails, bottom rails, balusters, etc.
Of the interior mill work the stairs are the most important. For the small house they should be very simple, not only for economy but for appearance. Plain round and square balusters, 1³/₁₆ inch, and two to a tread, simple hand-rail and simple newel post, 3¾ inches, are more effective than elaborately turned members. The height of the hand-rail from the top of the tread to the hand-rail on a line with the face of the riser should be 2 feet 6 inches. The slope of the stairs should preferably be confined between 30 degrees and 35 degrees, and the common proportion between tread and riser should be maintained (tread and riser = 17½ inches).
The treads should be of 1⅛-inch hardwood, and the risers of 1³/₁₆-inch softwood, rabbeted into the riser. Outside strings ought to be ⅝ inch thick where finishing on a ⅝-inch base. Inside strings should be 1³/₁₆ inches thick. Enclosed stairs between walls should have strings fitted down on treads and risers, but elsewhere inside strings should be rabbeted for treads and risers. Newels should be housed out over supports.
A feature of the small house which is neglected too much is the installation of built-in furniture. There is a substantial quality about such furniture which no mobile furniture can possess. The bookcase built into the wall, the window-seat permanently a part of the room, a charming mantel-piece, good panelling, built-in china-closets, tables, and benches in the breakfast alcove, a modern kitchen dresser with the equipment of a portable cabinet, dressing-tables, and closet shelves and drawers, medicine-cases and radiator enclosures are features which add so much to the small house that it seems strange that they are so often omitted. Many a speculative builder has realized the value of such furniture and sold his house upon the attractiveness of it. He knows that the young couple who purchases the small house usually comes from the small apartment, and has little furniture to spare. Here then is a place to spend money and not to economize.
