American Standard Revolving Doors 2512-14 MONROE STREET, CHICAGO A CATALOG of Revolving Doors, at its best, can deal only in generalities. No given scheme will fit with precision the needs of more than one occasion. Each building will vary in conditions, layout and finish with a correspond¬ ing difference in the door proper to serve it. The object, then, of this booklet is to present to architects, builders and interested laymen as well, in as clear and concise a manner as possible, the ad¬ vantages and uses of the American “Standard” Revolving Door, together with an explanation of its principle and description of its operation. The revolving door is a proved architectural tri¬ umph of unquestioned economy and practical effi¬ ciency. We hope that this booklet will convey to you an appreciation proportionate to its merit. AMERICAN REVOLVING DOOR CO., CHICAGO 1 The American “Standard” Revolving Door Is the recognized “Standard” of Revolving Doors. Its use in all parts of the country and in buildings costing millions of dollars is the best tribute to its usefulness. Its superior¬ ity over all old-style vestibules and regular front doors is so evident that in the entrances to our larger buildings no other door is considered. As a heat, fuel and money saver no other invention in recent years has contributed more to the health of the occu¬ pants or added more to the dividends of the owner of the building than the American “Standard” Revolving Door. American “Standard” Revolving Doors are built complete in our Chicago factory. The mechanical features are fully covered by Patent No. 906175, dated Dec. 8, 1908, owned by us and represent the most simple and efficient method of con¬ struction and operation in use today. Materials, workman¬ ship and finish are matters of special pride with us and are the best obtainable. Each door is erected complete before shipment, and oper¬ ated as a final test to prove that it is right in every particular. Every door is guaranteed against all defects of material, workmanship or construction. We furnish complete directions for installing the American “Standard” Revolving Door, and any intelligent mechanic who will follow them can install our door correctly. AMERICAN REVOLVING DOOR CO. Office and Factory: 2512-2514 West Monroe Street, Chicago. AMERICAN REVOLVING DOOR CO., CHICAGO Design A The “American Standard” Revolving Door. Its leading features: As a main entrance door of a building it takes the place of a number of successive swing doors. It requires no vestibule, as it is its own vestibule and therefore economizes space. It dispenses entirely with the un¬ sightly “Storm Houses ” and “Sheds, ” and their removal and re-erection every season. It makes the most conven¬ ient entrance, free from ob¬ structions and is as light and airy in appearance as if no win¬ ter doors were in use. Its ele¬ gant appearance makes its re¬ moval during the summer season unnecessary, and it is therefore a door for all the seasons. It is the most effective fuel saver ever devised. It is a door that never needs closing, cannot be left open, blown open or slammed. It accomodates a greater number of passers than any other door system, because it keeps the ingoing and outgoing crowds separated and thereby prevents collisions. Its exclusion of all street noises and the noiseless action of the door itself, the absence of checks, springs, bumpers and weights. Is especially important in churches, theatres, lecture halls, libraries and court rooms. The four rotating wings may be folded flat on each other and moved aside by one person single handed in a few seconds, leaving a free passage way for furniture, bulky packages or full ventilation in pleasant weather. The complete exclusion of all wind, rain, snow and dust during the severest storms, while people are passing comfortably in and out, is the crowning merit of the Revolving Door. AMERICAN REVOLVING DOOR CO., CHICAGO 3 The “American Standard ” Revolving Door consists of two segmental walls, a ceiling and the rotating structure Our illustrations, figures 1 and 2, show for descriptive purposes one of the most popular designs of a “Standard” Revolving Door, but any other design of walls, wings and cornice may be substituted. Dimensions The standard height of a revolving door structure between floor and ceiling is usually 7 feet, 7% feet or 8 feet. The inside diameter of the cylindrical ves¬ tibule is 6 feet, 6% feet, 7 feet, 7 y 2 feet or 8 feet. 4 AMERICAN REVOLVING DOOR CO., CHICAGO Various Positions of Revolving Doors AMERICAN REVOLVING DOOR CO., CHICAGO 5 The Two Curved Walls The two curved walls are made of a true circle in segment shape and each is horizontally about one and one-half inch wider than a quarter circle, in order that at least two of the wings are constantly in contact with the two walls, which makes them “always closed.” The inside of the walls must be made of a cylindrical true smooth surface. No beading, grooves or other irreg¬ ularity of this surface is permissible. The walls may be made of tongued and grooved material, held in shape by wooden or iron bands; or they may be framed together of curved stiles and bent rails, filled flush with bent wood or glass panels. Walls may also be of electroplated cast iron, cast bronze, marble, tile, concrete or any other suitable material. Curved marble bases, to correspond with base in hallway, may be placed under the wooden walls, to prevent marring the same from rrequent mopping of the floors; or sheet brass or bronze may be placed at the bottom of the curved walls to protect that portion of the woodwork from injury, but these last named features are not essential, they only add to the good appearance of the structure. The Ceiling The ceiling must be flat and smooth underneath and like the inner surface of the walls, beading, grooving or other irregularities must be omitted. The edge of the ceiling may be crowned with a neat moulding, design B, or a regular cornice may surround the ceiling, design A or figure 1. 6 AMERICAN REVOLVING DOOR CO., CHICAGO Diagram A Wings Revolving, “Always Closed” Diagram B Half Open Position Diagram C I olded and Fastened Centrally Diagram D Folded and Locked Diagram E Folded and Moved Aside The Rotating Wings The four rotating wings may be made in any popular design, but the fol¬ lowing items must receive consideration: Lightness —The wings should be as light as possible and still strong enough to withstand the considerable strain imposed upon them; heavy wings are hard to start and hard to stop and must therefore be avoided; bronze or cast iron wings, even metal covered wings are not recommendable. In regard to thickness of wood for wings one and three-eighths inch will answer all practical purposes. Kickplatea are a necessary adjunct to revolving door wings. We recom¬ mend not less than eight inches high and No. 12 gauge rolled metal; cast metal plates are impractical as being too heavy. Handrails are the means of pushing the wings around and one is sufficient on each at the approaching sides of the wings. Pushplates having the word “Push” displayed in large, distinct letters, show people in what direction to go; they don’t need to be of large size, as the door is not pushed forward by applying the hand on them, the handrail fulfills this purpose. Locking Bolts are attached to the upper edge of the wings, in order to lock them against unauthorized passage, or for holding them in an open central position. Two double cylinder Keylocks are attached when so desired to lock or unlock the structure from out or inside of the building. Felt and rubber Weatherstrips form an airlock at the top, bottom and vertical edges of the wings. The vertical weatherstrips are made extra wide to prevent the possibility of pinching hands and fingers; they are also set at a slight incline to make them noiseless and tend to prevent rotating the wings in the wrong direction. AMERICAN REVOLVING DOOR CO., CHICAGO Suspension Device As the four rotating wings of the “Standard” Revolving Door are so arranged that they can be folded together and moved to one side of the vestibule to clear the entire opening, they naturally cannot be made to turn on a pivot which rests on the floor. Therefore, and also for the purpose of keeping the bearing parts away from dirt and dust, the rotating structure is suspended from above, from a carriage which rests on a pair of channel irons, supported above the ceiling and extending from middle of one wall to the middle of the other wall. These channel irons are encased in a neat moulded box when a low crown moulding is used in place of a cornice, see design B, but with a regular cornice, design A, of not less than seven inches in height, the channel irons are completely concealed between the ceiling and the top cover. The wings are connected at their central upper edges to a kingbolt, K (see figures 3, 4 and 5), which top-end rests by means of a pin, P, upon an annular bearing plate, BP, supported by ball bearings, BB, confined in a dust- proof bearing cup, BC. Fiq 3. Top View ofU-ollev Devise. The balls of this bearing are absolutely true spheres, made of tool steel and move in a bronze casing on case-hardened steel rings. The bearing cup is supported on two wheels, WH, and forms a carriage, which, when not held rigidly in its center position, can be rolled forward and back upon the lower flanges of the two connected channel irons, Cl. But when the revolving door is to be rotated, this carriage, with kingbolt and suspended wings, must be held absolutely rigid in the center. For this purpose and to keep the channels in perfect alignment, a separator, SE, is placed in such a way near the middle of the channels, that, when the wings with their kingbolt are moved towards the center position, the two wheels stop against the flanges of the separator and cause lockplate, LP, to engage a hook shaped exten¬ sion, HE, of the carriage, which arrangement keeps the carriage confined to its center position until disengaged. For the purpose of keeping the wings at the floor in their center position, a steel pivot pin moving vertically in a bronze lined casting, fastened to the lower end of the inner wing edges, can be dropped down into a cast bronze floor socket and be lifted up when the wings are to be moved aside. The revolving wings, held at the bottom by the pivot pin entering the floor socket and at the top by the kingbolt carriage engaging the lockplate of the sep¬ arator, are now secured in such a position that they can be freely rotated. 8 AMERICAN REVOLVING DOOR CO..

Of the four rotating wings two opposite ones, called “permanent wings,” figure 2, are rigidly connected to each other by means of a metal cross bar, figures 6 and 7, which keeps both wings in proper alignment Strong metal drop braces, figure 8, hinged to this cross bar, are held in a horizontally extended position or dropped downward, out of the way. The other wings are hinged to the permanent wings, in such a way that they fold flat against their adjacent wings. To keep the hinged wings in extend¬ ed position, they are provided with metal sockets, SO, figure 8, which the ends of the drop braces engage. When it is desired to fold the wings, unhook the drop braces from their sockets and swing them downward, then fold the hinged against the permanent wings and catches, not shown in the cuts, keep the wings together, which may then he fastened in central open position by means of locking bolts, see figure 1, or swung across the vestibule to lock it completely. Sliding Device When the wings are folded and stand in central open position, they may be completely moved to one side, by lifting the bottom pivot from the floor socket and pushing against the lower part of the folded wings, which operation automatically disengages the overhead lockplate, and causes the entire sus¬ pended structure to roll on its wheels towards one side of the vestibule, where it will stop against the wall posts. The locking bolts are then pushed into their ceiling plates and the bottom pivot dropped into a side socket provided for in the floor. To restore the wings to their rotating position, withdraw lockbolts and bot¬ tom pivot, wheel back to the center, where the automatic catch in the ceiling will engage and retain the wings in center position. Then drop the bottom pivot into the floor socket and readjust the wings to their rotating position. AMERICAN REVOLVING DOOR CO..

Gentlemen: The two "Standard 1 ' Revolving Doors installed by your company in the New Lion House have been now been in use about ten months. As you know no expense has been spared to make it the model building of its kind in the world,and the fact that we have equipped it with "Standard" Revolving Doors, not from an economical stand point but because we had to have the best door,the door that would enable us to keep the building at an even temperature in the coldest weather so that our animals from the tropics could live free from draughts and colds. It will no doubt prove gratifying to you to know that your doors have satisfactorily passed in every trial.They are unquestionably economical from the fuel point of view especially is so large a building as this where a direct draft through would make heating a serious problem. Besides they allow us to handle systematically the largest crowds and no congestion is experienced.
