Itsgreatest speed was nearly at the rate of twenty miles an experiments are still more interesting. He constructed aflying machine on a large scale, its total weight when loaded being8,000 pounds, this including engines, boiler, fuel, stores, and threepersons. The boat-like body was moved by a powerful propeller, andthe lifting mechanism consisted of a great aeroplane, with smallerones projecting like wings, the extreme width being 105 feet, length104 feet, total area 5,400 square feet. He had constructed a rail-way along which this machine moved on wheels, the pressure on therails decreasing as the speed increased. In a notable experiment,made in June, 1894, the whole machine was lifted for a brief intervalfrom the ground. 369. RENARD & KREBS ELECTRIC AIR SHIP. Paris,1884. The electric motor was operated by current from storage bat-. teries. The form was peculiar, being somewhat like a fish, with thepropeller at the head. It was claimed to have attained a speed oftwelve miles per hour. 370. GRAIN-DRYING APPARATUS. For tumbling grain orother material in an inclined cylinder with a blast of warm air. A, a brick box in which coke isburned, or a flue to conveywaste heat from any fur-nace. B, compoundwrought-iron fan, whichwill draw waste heat froma distance of 50-100 , chimney and valve, tocarry off smoke when fire is first lighted, r, thermometer or ^ feed hopper, into which the grain is conveyed by an elevator frombelow, or by a chute from an upper floor.
