Anchors for Chairs 'T'HESE are expansion shell bolts used for anchoring theatre seats to the floor. They are made in several types. Type No. 1 is used with a carriage bolt and is inserted in the hole and set with a small setting tool before placing the chair in its final position. This tool is furnished without extra charge. The No. 2 type is used with a square head machine bolt which has been specially heat treated to prevent any possibilities of stripping the threads when drawn up tightly with a socket wrench. This type No. 2 is attached to the leg of the chair before placing the chair in position. The method of application is to insert the bolt through the hole in the leg of the chair and turn the expansion shell far enough up on the bolt so that it comes in contact with the under surface of the chair leg. This small amount of friction prevents the shell from turning around. The shells will withstand the constant vibration of raising and lowering the chair seats, as well as the motion and hard usage they must necessarily stand when the seat is occupied. The shells are furnished to the user complete, consisting of the expansion shells together with a washer and whatever style or length of bolt the customer may specify. Different makes of chairs take different lengths of bolts, and stock is carried to cover this variation. Bolts range from 1% inches to 3 inches in length.

Arc Regulators AS the name implies the arc regulator ^ regulates the voltage at the arc through automatic feeding as the carbon is consumed and the gap between the carbons increases. The result of this automatic action is a steady light on the screen pronounced superior to that which it is possible to produce by hand. The arc control, as it is frequently called, feeds the carbons in an even manner. This equipment sells for about $125. CHICAGO CINEMA EQUIPMENT COMPANY, 17361754 N.

Arc Lamps, Reflecting Refer to LAMPS, REFLECTING ARC A Arc Lamps, High Intensity Refer to LAMPS, REFLECTING ARC A Architectural Service TN planning a motion picture theatre, the services of a competent theatre architect are recommended. Such service may be comprehensive or limited according to the nature and size of the project. For example, an architect may be called upon to furnish complete plans and specifications for a theatre and the work of building a house let to a local contractor. In such cases, where the architect’s supervision is not arranged for, the cost of complete plans and specifications is 3 per cent of the cost of the project. On this basis the cost of plans and specifications for a $50,000 theatre, for example, would be $1,500. The regular architect’s commission as established by the American Institute of Architects, in which the architect renders full supervision throughout the construction period is 6 per cent. The architect’s fee for plans and specifications, usually results in a saving in various materials and labor which more than compensates for the cost of the plans, it has been found. His plans provide a safeguard against a building which might prove unsatisfactory from many angles if designed by someone who is not familiar with the special requirements of theatres. It should be remembered that a theatre is a highly specialized type of building. Even the architect who may be successful in designing factories, warehouses and industrial buildings of other types is not equipped to give an understanding to theatre problems which may be expected of the architect who has given this particular type of building an almost exclusive attention. The hazard of trusting the design of a theatre to a local contractor, therefore is readily apparent. He can usually be relied upon to perform satisfactorily the constructional work but the plans for the theatre require expert understanding if the completed job is to be successful and profitable.

A Artificial Flowers and Plants ly/TANY places in the theatre may 1 profitably be made beautiful through the use of art plants and flowers. The lobby, foyer, auditorium walls and organ grill offer excellent places for such use. Many theatres are capitalizing the seasonal rejuvenation it is possible to achieve in the house through the use of plants and flowers. Much progress has been made recently in the manufacture of beautiful art flowers, plants and trees of all kinds. Not only do art plants and flowers provide a natural beauty, in the theatre but they may advantageously be used in brightening dark corners and barren spaces.
