Copyright 1925 American Stove Company An Introduction to a Subject of Great Importance to Architects and Builders HE Lorain Oven Heat Regulator is the first perfect application of thermostatic control of heat to the oven of the domestic gas range. “Lorain” was invented in the Research Laboratories of American Stove Company, and is sold only as an integral part of gas ranges manufactured by the several divisions of American Stove Company, the world’s largest manufacturer of gas ranges. Lorain has been made and marketed suc- cessfully for over ten years. It is the original oven heat regulator. The Lorain Oven Heat Regulator is made and guaran- teed by the same stove company that manu- factures the stoves of which it is a part. It is the only regulator universally known to the American housewife. This is true be- cause of the extensive National Advertising which has been carried on uninterruptedly for the past six years. The name “Lorain” is carried in over 90,000,000 advertisements yearly. Thus, housewives the country over are thoroughly educated and sold on the ad- vantages of the Lorain Oven Heat Regu- lator. They know that Lorain insures per- fect results with everything cooked or baked in the oven, that it permits of the cooking of a Whole Meal while the house- wife is miles away enjoying herself, that it enables her to do her Canning in the oven — quickly, easily, cheaply, and with un- equalled results. By making it possible for the housewife to regulate and control the oven temper- ature exactly, the Lorain Oven Heat Regu- lator has made the art of “good cooking” easily acquired and more exact, rather than an art mastered only after years of dis- couraging failures. For this reason, more than sixteen hundred schools and colleges are Today using Lorain-equipped Gas Ranges to teach students the science of cooking. The Lorain Oven Heat Regulator has been approved by > ery vecogniz q kitchen in Americ keeping Institr’ New York Tribune Institute, Modern School of Cookery and the Testing House of Today’s Housewife. Moreover, with few exceptions, manufac- turers of nationally-known food products use Lorain-equipped gas ranges in their Experimental Kitchens and now include Time and Temperature in their nationally- advertised recipes. Satisfied tenants are the greatest asset the investment builder can have and noth- ing can be placed in his apartments which will go farther to bring about “tenant satis- faction” than the installation of a Lorain- equipped Range. Satisfied tenants stay “put” and every investment-builder knows what this means to him in actual dollars and cents. Once a woman has lived in a Lorain- equipped apartment she knows Lorain Service and will hesitate, if not stop, at renting another apartment where the kitchen does not have a Lorain-equipped Gas Range. Families are continually mov- ing from one apartment to another and Lorain-equipped kitchens are becoming more of a factor each year to hold tenants. Lorain-equipped apartments have a higher rental value, rent easier, and stay rented longer. From a rental standpoint the small addi- tional cost for Lorain equipment is the very best of investments as shown in the fore- going, but aside from this fact the addi- tional cost wil! more than be made up in the sayvinst vip nent-builder in his 20 itenz gb ae elimina- of repairs so 1; . u.., meeded on most stoves.

Eleven HANDBOOK on tA ls AN GC Ess Buildings Rent EasilyWhere Proper Attention Is Given to Gas Piping and Flue Outlets ( The following article is reprinted by the courtesy of the American Gas Association ) Gas in the Modern Building Necessity for Piping—The modern building most nearly approaches its point of maximum efficiency and maximum earning power when it presents for the use of its occupants the most complete facilities available in these modern times. To be complete, it must be adequately piped for gas. Manufactured gas, the use of which is now so general as to be almost universal, possesses many advantages as a source of energy. From the nature of its process of manufacture, storage and distribution, its continuity of supply is absolutely reliable. Gas provides an uninterrupted service— flexible in demand and uniform in quality. Its use goes a long way toward eliminating the costly and unsanitary smoke nuisance in our cities and towns as well as conserving our coal resources. Its use means a saving of time, through increased speed in actual operation, and the ability to secure uniform and more accurate control either manu- ally or automatically. It saves space, a tre- mendous advantage in modern building operations, since it eliminates the storage space required for other fuels and the space necessary for the storage of ashes, containers, ete. It saves labor (handling solid fuels, ashes, etc.), due to its peculiar adapta- bility to automatic control and it also assures a more uniform product. From practical experience, gas service is essen- tial in the modern building. In the home it has long been a necessity not only for cooking, light- ing, and water heating, but also for auxiliary and, more and more, complete heating from central heating plants. It is by no means unusual but rather the common experience to have prospective tenants of mercantile buildings demand this gas service in the premises which they are to occupy. This has, in fact, increased from year to year as both the uses of gas have multiplied and as the custom of housing light manufacturing concerns on the upper floors of mercantile buildings has increased. Now it is practically a universal de- mand for this service which, in a great number of cases, becomes a determining factor in the leasing of building space. Even in the office building, the practice of doctors and dentists, jewelers, chemists and small laboratories, restau- rants and clubs occupying space has made gas service a positive necessity in the equipment of the building. In addition, modern building principles call for the most permanent structures, so permanent that it is undeniable that they will outlast by many years the present generation. Due to this long life, the character of the occupancy and the uses to which the premises are put may change many times from those for which they were originally intended. Recent years have not only seen this condition but have seen complete changes of whole neighborhoods carrying with them a change in character of occupancy of every building in that locality. No building can be considered modern, complete or capable of answering all demands that can be made upon it unless its equipment makes possible the use of so efficient a source of energy aS gas. Gas in the Residence Gas in the residence is universally used for: Cooking Lighting Water Heating Auxiliary Heating Laundry Work More and more, in recent years, gas is also being used in central heating plants for either steam or hot water, with its advantages of clean- liness, space saving and positive automatic control. Gas in the Hotel Gas in the hotel is universally used for: Main Kitchens Pastry Shops Banquet Kitchens Water Heating Serving Pantrys Laundry Bake Shops Water Sterilizing Confectionery Shops Auxiliary Space Heating Gas in the Loft Building Gas has a great number of uses in the loft building such as: Water Heating Steam Boilers In addition, all manner of furnaces, burners, ovens, etc., using gas are used depending upon the type of manufacturing to which the building is devoted. Gas in the Office Building The modern office building uses gas for: Water Heating Water Sterilizing Kitchens (where clubs or restau- | rants are tenants, as is now gen- erally the case). Besides these, the increasingly common prac- tice of doctors, dentists and other professional men locating in this type of building, creates the demand for gas in many and varied small appliances. Cost of Piping The cost of gas piping, if put in at the time of erection, is relatively small when compared to the total cost of the building and compared to the increased rental value of the premises so equipped. This cost varies from 0.10 to 1.0% of the total cost of the building, the latter figure covering the most elaborate piping layout required to cover every possible contingency. But if the piping has to be put in after erection due to demands of Twelve (Ome tie Cigenn C lmsmean di. 3 OTD BARSS I cs 1 LE avec prospective tenants, which is a quite general case, the cost will be greatly increased, besides which the installation is liable to be unsightly and the work annoying and inconvenient to the occupants of the building. Size of Pipe Under the heading ‘How to Calculate Pipe Layout,” the method of arriving at the size of pipe needed for various requirements will be given. It is essential, however, that ample provision as to pipe sizes should be made at the start, so that any unknown contingency of future occupation can be met as well as the known present needs. The size of gas pipe necessary to install de- pends on the following factors: (a) Length of pipe. (b) Maximum gas consumption to be pro- vided for. (c) Allowable loss in pressure from service pipe to appliance. (d) Specific gravity of the gas. The specific gravity of most gases varies be- tween .45 and .65, and as the capacity of pipe is only affected by this factor inversely as the square root, it is sufficiently accurate to use an assumed gravity of .6 for all calculations. Tables 1 and 2 are both based on this value but if it is desired to use the exact gravity for a particular condition, the values in the two tables can be corrected by 0.6 Sp. gr. The unit for measuring the pressure of manu- factured gas is inches of water, and it will be noted in Table 1 that the gas capacities for the various pipe sizes are given for a .2-in. pressure drop. In Table 2 the drop allowed is .5-in. These two tables are given in order to compensate for the different conditions encountered in calculating lateral feed pipes as against vertical or riser pipes. Table 1 is for laterals and Table 2 for risers. There are two reasons which permit a greater pressure drop to be allowed on risers. First, the drop in pressure due to the ordinary friction loss is reduced by the gas column which is lighter than air and therefore causes an increase in pres- sure with altitude. For a gas with a specific gravity of .6 this increase is approximately 1 in. (of water) per 170 ft. of elevation. Second, the possibility of all gas appliances be- multiplying by TABLE 1 Showing Capacity of Pipe of Different Diameters and Leneths in Cu.

A greater diversity can be expected when we include a variety of uses than when only one use is considered and a more liberal factor can therefore usually be allowed for risers than for laterals. In order to show how Tables 1 and 2 can be used in designing a pipe layout, an example ap- plied to each will be given. Assume that a hotel is to be erected with gas requirements as called for in Fig. 1 (next page). The number marked in each rectangle is the maximum gas demand for each requirement and is expressed in cu. ft. of gas per hour. The hotel is 16 stories high with a basement and sub-basement. On the roof there is a restaurant with a kitchen having a maximum demand of 1500 cu. ft. per hour. The tenth floor has a banquet kitchen, the first floor a barber and tailor shop, the basement contains the main kitchen, bakery and laundry and the sub-basement a water heater and drinking water sterilizer. On each of the room floors there are service pantries and radiant fireplace heaters in the sitting rooms of the suites. To figure the size of the risers, start at the top floor. Here we have 1500 cu. ft. which must travel through 270 ft. of pipe; refer to Table 2 and we find it will be necessary to provide 3-in. pipe. On the sixteenth floor we have 1500+-400— 1900 cu. ft. which must travel through 255 ft. of pipe; this also calls for 8-in. pipe, etc. (See com- putation table on Fig. 1 for complete layout.) The service will have to supply 18,000 cu. ft. per hour and as it is 45 ft. long we find from Table 1 (laterals) that this calls for 6-in. pipe. As an example for calculating pipe sizes for laterals we will figure the requirements for the basement where we have the main kitchen, bakery and laundry. Fig. 2 (second page following) shows a plan of this floor, and it will be noted that the kitchen which has a demand of 3000 cu. ft. per hour is located 45 ft. from the riser. Refer to Table 1 and we find that it will require 3-in. pipe for this section. The laundry and bakery are so located that it will be necessary to have a common lateral for both as far as to the laundry. The common run for both is 120 ft. long and will have to provide for 2000+1500—3500 cu. ft. (4-in. pive). From the laundry to the bakery is 60 ft. additional, making a total of 120 ft.+60 ft—180 ft., with a demand of 1500 cu. ft. per hour. Table 1 shows that 180 ft. of 3-in. will pass 1600 ft., which is therefore ample. TABLE 2 Showing Capacity of Pipe of Different Diameters and Lengths in Cu.

Layout for Basement Selecting Appliances In selecting gas appliances for installation care should be taken that only the best appliances— quality merchandise—are selected. ‘The Amer- ican Gas Association through its Committee on Standard Gas Appliance Specifications, has drawn up specifications for the construction of gas ap- pliances which insure the greatest efficiency, dura- bility and service. These specifications have been adopted by the leading manufacturers of ap- pliances and by the gas companies. Before select- ing the appliances, therefore, consult with the local gas company to insure getting only standard appliances. Installation of Gas Appliances The most important factor that affects the safe and economical operation of gas appliances is the provision of adequate supply piping. This will assure constant and sufficient gas pressure and will result in the uniform operation of gas burners under conditions of proper combustion. In the actual installation of gas appliances, the factor of ventilation must always be carefully considered. A properly designed appliance, oper- ating under correct adjustment, will, when burn- ing, produce only carbon dioxide and water vapor, both of which are absolutely harmless. It is neces- sary, however, in order that this condition be maintained, that sufficient ventilation be provided. If, therefore, large gas consuming appliances are to be installed in relatively small spaces, a flue or chimney connection is necessary. Further, gas appliances operating under automatic control should always be vented, as should all appliances installed in bathrooms. This practice should never be deviated from unless the room is very large and provided with exceptionally large win- dow surface. In the case of individual room heaters for use in the various rooms, they can be operated safely Fifteen without vent connections provided that they do not exceed the correct heater capacity (equivalent square foot rating) for each room. If they do not exceed this heater capacity, the heater or heaters can burn in- definitely in a room having approxi- mately three air changes per hour without ever raising the carbon dioxide content to a proportion that will be in the least measure harmful. Where flues and flue connections are necessary, these chimneys or flues should be of the same size as required for solid fuel appliances of equivalent capacity. As for design and material, the specifications of the National Board of Fire Under- writers should be followed. Smooth tile lined flues are very satisfactory for venting gas appliances. The cases quite frequently found where makeshift vents for gas ap- pliances have been installed are due to the fact that sufficient flues to care for the various re- quirements are seldom provided in buildings. As an example, every cellar should have at least two flue outlets, one for the heating boiler or furnace and one for the hot water supply heater. The American Gas Association urgently recommends the more general provision of flues in buildings and homes. The A. G. A. The American Gas Association will be glad to consult with architects or builders and through its engineering staff at the headquarters office, advise on any questions relating to gas piping or selection or installation of appliances. In addition, the Association has printed from time to time complete information on such subjects as selec- tion, design and installation of water heating in- stallations, design and installation of central house heating installations and various books on the many industrial applications of gas which should prove of great value to the architect and builder. They will always be glad to be consulted on any matters relating to the piping of buildings and to aid in the selection of the proper installa- tions of gas appliances of all descriptions. Summary The observations and study given to building problems by engineers of the American Gas Asso- ciation show conclusively that buildings where ample provision has been made for gas piping and flue outlets are those most easily rented. If, therefore, ample gas piping is provided when buildings of all classes are erected, if ade- quate provision for flues is made, such structures will be thoroughly equipped to make use of gas, thereby assuring greater flexibility, enhanced revenue possibilities, greater comfort and economy for their tenants and the nearest approach to permanent efficiency as a whole which it is pos- sible to attain.

Twenty-two foe Op aiee, Ces and BU TIX DIE RS Planning the Kitchen HE KITCHEN is primarily a workshop. Let us have beautiful kitchens without the sacrifice of utility. The kitchen should be planned with the same regard for the economy of time and labor demanded in the planning of any other workshop. The first qualification of an efficient kitchen is its suit- ability to the kind of work to be done in this home shop, and the number of workers it must house. Modern Kitchens are Smaller The smaller kitchen, compact and well planned, means fewer steps to take and a smaller area of floor covering to keep clean. One hundred and twenty square feet is a good size for the ordinary average-family kitchen. The large kitchen of the old farmhouse was used as a dining room, living room and laundry, to say nothing of the less important uses. Today, the most common outside work to be done in the kitchen is the ironing. This requires but little extra space, if care is taken to place the ironing- board (with adequate lighting and the plug for the electric iron) in such a position that it does not interfere with the use of other work centers in the room. This is very important, because in most homes, even in those not having permanent help, there is an extra helper for laundry work, and we must count on two people in the kitchen on ironing day. Construction and Finish for Cleanliness The real work of the kitchen is the preparation of food and the clearing away after meals. Cleanli- ness, not just the appearance of cleanliness, is what the Home Manager strives for in the kitchen. The simpler the construction and the smoother the surface of the room itself and of everything in it, the easier it is to keep the work- shop clean. Plain surfaces, rounded corners, and the elimination of mouldings and panelings leave fewer lodging places for dust and dirt. Every surface should have a washable, non-absorbent finish. Tile is the ideal wall covering and should be used in every case where price permits. Enameled woodwork and plaster, or commercial oil-cloth wall covering makes a good combination with the tile wainscot. Inlaid linoleum or composition floor cov- ering are better for the kitchen floor than tile, be- cause less tiring to the worker. The floor of un- covered wood is difficult to keep clean, and is less attractive in appearance. Twenty-three Beauty in the kitchen is achieved through the appearance of simplicity and cleanliness. An un- cluttered, well-lighted kitchen needs no ornamen- tation. A dainty stencil on the wall, or a touch of color at the window are attractive in some kitchens, but usually the simpler, the more appro- priate the result. Tinted walls are growing in popularity and there are a number of reasons for this. The all- white kitchen suggests the cleanliness of a hos- pital or a lunch counter. It was the result of a commendable effort to get away from the dark, dingy colors of the kitchens of twenty years ago. But with all-white kitchens, especially the glossy finishes, a glare results which is hard on the eyes and nerves of persons spending any length of time in the room. The best place to use the all-white kitchen is in a house which has a sun-exposure that makes a very dark kitchen. This is often the case in apartments. Of course, the more white; the lighter the room will be, but a note of contrast can be introduced without spoiling the effect of light and cleanliness. Ivory, cream, light buff, and the lighter softer grays, greens and blues are taking the place of white as the predominating color for the kitchen. In a room having a cold, dark, northern exposure the warmer tints of ivory and light buff can be used to advantage, while a kitchen having a sunny southern exposure needs the soft blues and grays to give the effect of coolness in summer and to soften the glare of the sunlight. It is a real econ- omy in heating, as well as a help to the cook, if this “warmest room in the house” can be given the northern sun-exposure. Less heat will be needed in the winter, and the kitchen will be more com- fortably cool in summer. Ventilating and Lighting Cross-ventilation is valuable in keeping the kitchen well-aired and free from odors. A built- in dome hood over the stove area is a help, espe- cially if an exhaust fan is provided in the flue. Transoms and high windows help give ventilation as well as good cross-lights on the working surfaces. The most practical arrangement of artificial lighting fixtures is to place a ceiling fixture of the indirect type in the “‘busiest” part of the kitchen. This should diffuse the light over the whole room TICADNGD OO Kaeo n without glare. Wall-bracket fixtures near the sink, work table, and stove will eliminate cross- shadows and murky corners. Standard Height Equipment The height of equipment is one of the factors which make a kitchen efficient or otherwise. Just as the equipment of a factory must be usable, so the worker must be considered in placing the sink and other work surfaces of the kitchen. The cor- rect height of all table surfaces for the woman of average height is approximately thirty-two inches from the floor. This will bring the top of the sink up to about thirty-six inches from the floor in order to have the bottom, or working sur- face of the sink at correct height. The Convenient Sink The ideal sink unit has two drain surfaces, so that dishes may be scraped and stacked at one side and placed to drain at the other side, after washing. The cupboards above the sink “counters” save steps. Dishes can be put away after wash- ing, without carrying them across the room. When it is possible to place the sink next an outside wall a window should be placed above the sink. This gives good light and a view which is much more interesting to the person working at the sink than a blank wall or a cupboard door. A neat shelf beneath the window ledge makes a convenient place for storing the supplies and small utensils needed at the sink. Otherwise the window ledge is apt to become a “catch-all”. Built-in shelves and drawers make good use of the space under the counters at each end of the sink, but the space directly under the sink should be open and uncluttered. Whenever practical, have the outlet for the water and soil-pipes be- neath the sink in the wall rather than in the floor. The floor is cleaned more frequently than the wall and should be kept free from obstructions which make cleaning difficult. The Step-Saving Cabinet The kitchen cabinet provides the best work table unit. The grouping of supplies and utensils in such a way that those most frequently used are nearest at hand, is best accomplished in the stock designs of the nationally advertised kitchen cabi- nets. Built-in cupboards for bulk supplies and for utensils which are seldom used, can supplement the cabinet, where space is available, but they cannot take its place in the efficient, convenient kitchen. Cold Storage in the Home The refrigerator is perhaps the one piece of GAS RANGES equipment easiest to vary to meet space require- ments, inasmuch as it is always more or less of a special-order proposition. The refrigerator should be placed as far as convenient from the range, to save useless melting of the ice from excessive heat. An alcove near the back entrance is a good location as it saves cleaning up after the tracking in of the iceman. The “outside icer” is a conven- ience, and should be used in every case where the refrigerator can be placed next an outside wall. Most manufacturers will furnish refrigerators “unfinished” so that they can be finished to match the rest of the woodwork in the kitchen. The dealer will order them at the request of the buyer. Electrical refrigeration is growing in popu- larity and in the better homes, the people are realizing that the larger initial expense is the true economy in the end. The refrigerator should have an ice capacity of at least fifty pounds for the small apartment and not less than one hundred pounds for the small detached house. The walls of a well insulated re- frigerator are so thick that it is impractical to at- tempt the use of the “‘side-icer” or three-door type in a very narrow space. Where inches are an im- portant consideration, the “apartment style” with the ice compartment across the top is the best so- lution of the space problem. The lining of the food compartment should be of smooth, seamless porcelain or other non-porous material which is easily kept in sanitary condition. A drain-pipe should be connected to the refriger- ator to save the nuisance of a sloppy “water-pan”. Drain pipes must not be connected direct to sewers. The Lorain-equipped Gas Range In space for the Gas Range, allow fifty to fifty- five inches for the modern range of the cabinet type having one baking-oven and one broiler beside the cooking top. Ranges having more ovens for use in larger homes require sixty to eighty inches. Lorain-equipped Gas Ranges are made in sizes and types to fit every kitchen. They are made in a variety of finishes to harmonize with any plan. The more white enamel used in finishing the range, the easier it is to keep clean. The smooth, hard finish is easy to wipe off, and the white parts help make the work surface light. If the range is to be placed in a corner of the room, the oven should be next to the wall leaving the top cooking-surface toward the open space, and nearest the light. Space should be allowed between the Gas Range and the wall, for conven- ience in cleaning. The measure and control of Twenty-four essai jeder igen Cris wand.

The Lorain Oven Heat Regulator is essential to the really modern, efficient kitchen. A kitchen without a Lorain Oven Heat Regulator is like an office without a telephone. The Home Manager of Today is asking for up-to-date, scientific kitchen equipment to lighten labor and save time. She knows that the Lorain-equipped Gas Range gives perfect baking results—a new, easy, safe way to can—and a “Magic Chef” to watch the Whole Meal Oven Cookery. Grouping Equipment for Efficiency The arrangement of the equipment according to working routes is the final step in the planning of a labor-saving kitchen. If we plan the order of procedure in the kitchen as we would the work of a shop or office, it is a simple matter to arrange the “work centers” in convenient sequence. All kitchen work can be grouped around five centers, namely,—Storage; Preparation; Cooking; Serv- ing; Clearing after meals. 1. The storage of bulk supplies, and utensils T wenty-five seldom used, form the first center, which can be farther from the Gas Range and other units. 2. At the cabinet or work table we must as- semble the cutlery and cooking utensils as well as the supplies for every-day use, placing the things most frequently used in the most accessible posi- tions. At this center all preparation work is done and foods are ready for the actual cooking which is done at the next work center. 3. The Lorain-equipped Gas range, placed be- tween the Kitchen Cabinet and the serving table, is the “cookery center”. All related equipment, and all utensils used only at the Range should be grouped conveniently near by. 4. The “serving center’ is the shelf, counter, or table near the stove, upon which to place the hot dishes as they are taken from the oven. This table should have a heat-resisting metal top. 5. Of course the central unit of the “clearing group” is the sink. The stacking surfaces, the cupboards for dishes, the incinerator or other re- ceptacle for scraps—all tools and supplies for clearing away after meals, belong near the sink.

The heat of the oven causes this tube to expand or, in other words, to lengthen. Inside of this copper tube is a porcelain rod “H,” which is held against the plug “J” by the pressure of spring “M” against lever “K.” Variations in temperature do not affect the porcelain rod in any way. For instance, as the copper tube lengthens according to the oven heat, the porcelain rod “H” follows along with it, releasing the tension on lever “K” and spring “M.” This causes the valve-plunger “N” to move nearer the valve “S,” reducing the flow of gas to the oven burner through the orifice “U.” As the oven cools off, the action is reversed to maintain the selected temperature. In this manner different temperatures are obtained and maintained by turning the Red Wheel to vary the position of the valve-plunger “N” in its relation to the valve “S.” For instance, if the Red Wheel is set for a high temperature, the plunger “N” will be farther away from valve “S.” Thus, more heat in the oven is required to make the copper tube “G” expand sufficiently to cause the lever “K” to move the plunger close enough to control the flow of gas at “S.” Again, if the Red Wheel is set for a low temper- ature the plunger “N” is brought closer to the valve “S,” requiring less heat in the oven to control the flow of gas.
