The fuselage was torpedo-shaped, having a section four feet square at the point where the aviator sat, and tapering sharply to a point in the front, and more gradually toward the rear. The nose of the machine was made up of sheet aluminum, having a series of holes stamped in it to permit of efficient cooling of the 14-cylinder Gnome. The main planes were attached to the centre of the fuselage in a position just behind the engine, while at the rear of the fuselage were the small triangular-shaped elevator and the vertical rudder. A three-bladed propeller was used. The dimensions were: length over all, 20 feet 6 inches; spread, 32 feet; width of wings, 8 feet wide at the body, tapering slightly toward the tips. TWOMBLY Mr. Irving W. Twombly exhibited a Bleriot-type monoplane which was fitted with one of his 45 horse-power 7-cylinder air-cooled revolving motors. The planes were covered with transparent celluloid in the vicinity of the body for the purpose of affording the pilot a good view of the ground immediately below and in front of him. Another exhibit of Mr. Twombly’s was a shock-absorbing safety harness of his own invention for strapping aviators in their machines. This harness was so constructed as to prevent the aviator from being lurched out of his seat, and yet at the same time permitting him to quickly detach himself from the harness in case of emergency. NIEUPORT The Aero Club of America exhibited a 50 horse-power Gnome Nieuport aeroplane. QUEEN The Queen Aeroplane Company exhibited two machines, one an aero-boat designed by Grover C. Loening, and the other a Bleriot-type monoplane equipped with a 30 horse-power Anzani motor. The aero-boat consisted of an aluminum-covered boat, to which were attached in front on an upright structure the main wings, with the motor and propeller just behind them. The power-plant consisted of a 50 horse-power Gnome, which was placed in the boat proper, and drove through a chain the propeller, which was just behind and a little above the main planes. The controlling arrangement was quite novel, and consisted of two horizontal levers resembling the tillers of a boat, which the operator grasped one in each hand. NATIONAL The National Aero Company exhibited a Bleriot-type monoplane which was equipped with a 4-cylinder 40 horse-power Rubel “Gray Eagle” motor and Rubel propeller. The motor was fitted with an acetylene self-starter, which was controlled from the seat. AMERICAN The American Aeroplane Company exhibited a large monoplane with a very low centre of gravity. It was fitted with two 50 horse-power 2-cycle air-cooled revolving motors and self-starters, and was designed to fly with either motor, and to carry six to ten persons. THE FIRST PAN-AMERICAN AERO SHOW It is notable that no engine exhibited at this exposition had more than 80 horse-power, whereas the Liberty motor of 1917 developed 450 horse-power and the Fiat 700 horse-power.
