Abstract
468,092. Retractable undercarriages for aircraft. FAIREY AVIATION CO., Ltd., and ORDIDGE, F. H. April 24, 1936, No. 11755. Addition to 450,929. [Class 4] In a retractable undercarriage of the kind described in the parent Specification, a wheel or like member 11, Figs. 1 and 2, is carried by a strut 12 to which is pivotally attached at 20 an oleo leg 16, 17. Cylinder 16 of the oleo leg is formed with a slotted guide 21 in which is slidable a block 22 universally attached at one end of a strut 25. Block 22 is also universally attached to the ram of a hydraulic jack 30. The wheel is retracted in a fore-and-aft plane and also movable radially as indicated in Fig. 1, to this end the upper ends of cylinder 16, strut 12, strut 25, and jack cylinder 30 are connected to the wing structure by universal pivots. In a further modification of the undercarriage described in the parent Specification, Fig. 4, cylinder 35 of a wheel-carrying leg adapted for lateral retraction is braced in the fore-and-aft plane by a strut 48. The retracting mechanism is similar to that of Fig. 2 but displaced through a right-angle. In a further modification, Fig. 5, a strut is formed as one arm 58 of a bell-crank lever pivotally mounted at 63 and of which the other arm 59 is pivotally connected to the piston rod 61 of a hydraulic jack. In all cases where the wheel is retractable about a transverse axis, the leg cylinder may be braced by struts pivoted about fore-and-aft axes to the lower part of the cylinder, extending upwardly and outwardly in a transverse plane, and pivoted about transverse axes to the aircraft wing.
