These instruments may be played either manually or by roll. The instrument is usually placed in the center of the orchestra pit. The pipes are mounted directly behind the upright console and the whole occupies only a slightly larger space than an ordinary upright piano. Other pipes are contained with the console, such as flutes, quintadena, etc., and a number of orchestral combinations and effects are possible with an automatic organ. It is possible, also, when using rolls, to operate the instrument from any point of vantage in the house such as the projection booth, manager’s office, etc., by simply pressing a button on the remote control board. Music rolls for automatic instruments have been developed that will play continuously for more than one hour. The roll may be reversed or jumped to any point of its length to obtain appropriate music for the particular action on the screen. Instruments of the above type range in price from $2,000 to $2,500.

They may be obtained in units ranging from 1-6 h. p. to 75 h. p., which are multi-stage, multi-pressure machines. These machines are made so as to give the proper wind supply for the size organ for which it is desired. Kinetic Engineering Company, Lansdowne, Pa. Spencer Turbine Company, Hartford, Conn. Zephyr Electric Organ Blower Company, Orrville, O. Organ Chimes ^HE theatre organ, in the range of musical instruments which it reproduces, is orchestral in performance. Perhaps no musical instrument is as responsive to the human touch. Chimes, marimbas, harps, vibra-harps, celestes, xylophones, bells, glockenspiels — the range of instruments is limited only by the prices of the instrument installed. And each instrument must be as finely constructed as the instruments used by the orchestra. J. C. Deagan, Inc., 1770 Berteau Avenue, Chicago, 111.

Electric heaters with thermostat control are used for this purpose. Organ chambers are usually tuned at a temperature of from 65 to 70 degrees. If the temperature is allowed to drop 10 degrees below the tuning temperature the metal pipes become flat by a quarter or half tone. A 10 degree rise above the tuning temperature will cause the same pipes to become sharp and further rise puts many of them out of pitch. The effect of dampness is to cause a swelling and consequent deterioration of wooden chests, pipes and other parts in the chambers. Since organ chambers are not standard in size the amount of heating equipment must be determined for each chamber. The larger the chamber or the greater the area exposed outside walls, the larger must be the wattage of the heater installed. Heaters should be mounted near the bottom of exposed or outside wall so that rising warm air from heater will counteract the descending columns of chilled air. Thermostats should be located at the point the best circulation takes place and out of reach of direct heat from heaters. Organ loft heaters may be so constructed as to deflect the heat back to the floor of the organ chamber, allowing the hot air to mushroom out before rising through the organ mechanism. This is accomplished by a hooded top. In large theatres operating afternoon and evening heaters are usually left in operation 24 hours. In smaller houses they may be disconnected when the show is over and started again by simply throwing a switch when needed. Prices range from $48 to $110 per set.
