432,868. Aircraft landing - gear. FRIEDEL, M., 202, Czerniakowska Street, DABROWSKI, J., 4, Danilowiczowska Street, GUTTMANN, J., 3, Holowki Street, and DWORAKOWSKI, K., 3, Holowki Street, all in Warsaw. Oct. 30, 1933, No. 30092. Void [Abridged as open to inspection under Sect. 91 of the Acts, May 3, 1934]. [Class 4] Aircraft landing-gear includes links 1, 2, 3, 4 and 5 articulated together as shown, and a further link 11, which incorporates a shockabsorber 12, is articulated to the links 4, 5 and to the link 1 which incorporates a shockabsorber 12, is fixed or hinged to the fuselage or wing, and is inclined forwardly. Leading and trailing wheels 8, 9 are provided, a carriage 6 carrying wheels 7 is articulated on the link structure and an elastic endless band passes over the wheels. The landing-gear may have spring-controlled lateral movement about the axis of the link 1. In a modification, the links 4, 5 are omitted, the link 11 being articulated to the link 3 at one of a number of positions intermediate its ends. In a further modification, a shock-absorber 12<1>, Fig. 7, is interposed across the diagonal of a quadrilateral formed by links 1', 2<1>, 31 and 11<1>, a carriage 61 carrying wheels 7 being articulated on the pivot of the links 2<1>, 31. Two such constructions may be placed adjacent each other on each side of the aircraft. In a further modification, the undercarriage is built up of two systems 6<11>1 and 6<11>2, Fig. 10, of interarticulated links mounted on the aircraft through links 11<11>, 1<11>. The shock-absorbers may be located at the hinge connections of the links.
