Trailer Chapel Has Speaker System (Jul, 1939)
Trailer Chapel Has Speaker System
Built into a trailer, a chapel on wheels brings church services to isolated mountain sections of Virginia and West Virginia. Its rear wall unfolds to form a platform before the altar, and a canopy containing two loudspeakers for a public-address system, which carries the preacher’s voice to the congregation. A gasoline-driven generator mounted in the back of the sedan that draws the trailer supplies electric power for the public-address system and for cooking and lighting. Supplemented by a storage battery, the generator unit automatically starts when a light or appliance is turned on, and stops when all are switched off.
