Abstract
440,358. Aircraft landing-gear. HAWKER AIRCRAFT, Ltd., DAVIES, S. D., and DOWN, C. R., Canbury Park Road, Kingstonon-Thames. June 27, 1934, No. 19008. [Class 4] In a'retractable undercarriage, a leg, which may be resilient and telescopic, and which swings upwardly and laterally for retraction, is pivoted about two axes and constrained in its path by an articulated radius rod so that during its swinging movement its outer extremity moves also in a fore and aft direction. A rod 13 secured to the leg 6 is rigid with a rectangular box-member 14 rotatable on an axis 22 carried by a sleeve 23 slidable on a bar 5. The member 14 has an integral arm 15 formed with a fork 16 in which is carried a rod 17 having a fork carrying a pin 18 on which rotates a small joint 19 which is pivoted on an axis 20 in a fixed bracket 21. When the jack 11 is operated to effect retraction, a trunnion 7 is rotated on the bar 5 so that the wheel 1 is swung laterally. The sleeve 23 is rotated and the normally straight composite rod 15, 16, 17 is broken by bending at the joint 6, with the result that the sleeve 23 slides away from the trunnion 7 and the wheel 1 is given a rearward movement during its lateral swing. The undercarriage may be locked in either or both positions by the engagement of a pin in a hole 9A formed at the apex of a triangular frame constituted by rods 9 connected to the leg 6. The operating arm of the arrangement may, as shown in Fig. 5, comprise a cylinder 24 connected to a triangular frame 28, 29, 30 connected by a knee joint 32, 32A to an arm 33 pivotally connected at 34 to the leg 6.
