THE BALDWIN BIPLANE.

   ANOTHER machine that is attracting considerable attention in America is that employed by Capt. T. S. Baldwin at Mineola. The span of the main planes is 36 ft. 3 ins., which length is divided into five sections of 7 ft. 3 ins., each representing the distance between a pair of main struts. The chord is 3 ft. 8 ins., and the gap 4 ft. 6 ins. Midway in the gap, and at the lateral extremities of the machine, are two balancing planes arranged on the Curtiss system. They are controlled by a lever forming the back of the pilot's seat. The rudder and the elevator are likewise controlled on the Curtiss principle by a vertical steering wheel mounted on a pivoted column. In this machine the elevator is a cambered monoplane, having a o ft. span and a chord of 2 ft. 8 ins. The tail, on the other hand, is a biplane, and is so constructed that the normal angle of incidence can be adjusted by the tension of the tie wires used in the bracing. The spars of the main planes have a section of 1 3/4 in. by 1 1/4 in., and are nearly elliptical in section. The struts measure 2 1/2 in. by 1 in., and have a section as shown in the accompanying sketch. Spruce is employed for the spars and struts, except in the case of the two rear centre struts which are made of steel tubing and assist in the support of the engine bearers. The front centre struts, although made of timber, are of much stronger section for the same reason.
