separating the first six to ten rows from the rear rows. This portion can then be designated as a loge and command the higher prices.

The level of the floor for the first row of seats must be raised sufficiently above the cross aisle to bring the eye line of the occupants above the heads of those using the cross aisle. This measurement should be at least 2 feet and 6 inches, a few inches more would be preferable. Seat steppings should be at least 83 inches in width and more if possible. The stadium facia rail should be of solid masonry construction and either finished with cement plaster or linoleum, and should project above the level of the first row fioor, 2 feet and 4 inches.

The solid portion of this rail can, if desired, be reduced to about 1 foot and 8 inches above the level of the seat bank, with an open ornamental metal or wood railing on the top. An open railing for the full height is not desirable, however, on account of the eye line of the persons passing in the cross aisle. Some times and ordinary pipe railing is used in this location and covered with removable fabric drapes or skirtings. This method permits the patrons in the first row to extend their feet through the rail into the aisle and interfere with those passing.

It will be quite impossible to prevent the front row occupants from resting their feet on this railing and exerting considerable pressure, and this fact must be taken into consideration in the (lesign so the rail will take the abuse to which it will be subjected. To provide sufficient toe and leg room, the first stepping should be at least 4 inches wider than the balance of the steppings.

All suggestions in the preceding paragraphs apply to similarly located railings in a balcony or mezzanine, with exception of the construction of the front railing. On account of the weight of solid masonry this should be constructed as shown in (Figure 22).

The sight line for the stadium seating should be figured over the head of the first row in front rather than the second row as recommended for the orchestra seating. This will, in most cases, result in a total rise for each stepping greater than 73/4 inches, which is the limit under most codes, and will necessitate the introduction of intermediate steps in the aisles. These steps should fill the entire width between the seat standards on either side of the aisle to prevent accidents.

The steppings in the aisle should be depressed {as of an inch for carpet and carpet strips installed at the angle of each tread and riser. A Wood carpet strip the full height and bolted to the face of the riser as shown in Figure 23, is more expensive but provides the best fastening and will result in less wear on the carpet.

Figure 24 shows another method for installing carpet on steppings, using a patented rubber nosing strip. This rubber strip can be had in most colors to match the predominant colors, which is sonwtimes desirable in a well lighted stair, but in the case of aisles in balconies, stadiums or mezzanines, the strip should be white in color to define the edge of" the steppings.

These rubber nosings are rather ex 1947-48 THEATRE CATALOG

pensive so far as the first cost is concerned, but since their location is at the point of greatest wear, the ultimate savings in carpet replacement, and insurance rates on account of fewer accidents will more than compensate for the cost of their installation.

Aisle lights should be provided on every other row on each side of the aisle, and be staggered to provide lighting on each stepping. Side aisle seat standards should be provided with aisle lights at each row. Provision should also be made for step lights in other locations, especially at the intersection of the aisle and the cross aisle, to illuminate the steppings for their entire length.

The stadium plan will often provide sufficient space underneath the stadium for most of the necessary toilets and service rooms. Ample headroom to permit most of this space to be used can be realized by the use of a few steps down from the foyer level.

In many cases, it will be necessary to install doors in the vomitories to eliminate the possibility of noise and light entering the auditorium from the lobby or foyer.


When it is desirable to provide from two to three hundred seats in addition to those that can be provided in the orchestra, the mezzanine with from ten to twelve rows will many times be the best solution of the problem. Since a certain portion of the mezzanine will overhang the orchestra seating area, it will be necessary to provide cantilever supports for the front part of the mez zanine, to preclude the necessity of colums in the orchestra seating area which would ruin the view from many orchestra seats. This type of construction is not especially costly as columns supporting the fulcrum beams can be located at the line of the standee rail where they will cause no such interference.

The height of the mezzanine in relation to the other fioor levels will be determined by the necessary location of the forward edge or toe of the finished mezzanine soffit which should clear the line of sight from a person standing at the standee rail to a point approximately 20 feet above the stage or platform at the screen location. With this point located and the thickness of the finished ceiling and construction determined, the level of the first or front seat bank of the mezzanine can be obtained.

The rise of the second seating bank above the first should be determined by figuring the sight line from this level over the head height of the first row head to the elevation of the bottom of the picture. However, in order not to have a steep pitch, this rise should be no more than 9 inches so that no intermediate steps will be necessary in the aisles. The actual rise of the step in the aisle can be reduced to 7% inches by sloping the seat platforms from the rear to the front, and seat standards installed to accommodate the slope. By using the same rise between all rows, the sight line will progressively improve for the seats behind the second row.

The notes on aisles, aisle lighting, rails and steppings included in the para FIGURE 20-The standard rockwool bat is 2 feet wide by 4 or 8 feet long, and should be hung vertically and securely nailed to wood grounds installed on the masonry walls around the perimeter of the panels, and horizontal grounds 24 inches on center in the panels. These grounds should be 1 inch thick (in order to provide the required air space behind the rockwool) and 2 inches wide.
