As described, two undercarriage legs, each comprising a landing wheel mounted between two parallel tubular members and each braced by a pair of jointed struts, are extended and retracted by a reversible electromotor driving all the winches simultaneously. Fig. 3 is a side view showing a tubular member 5a of one of the legs pivoted to the aircraft at 8a and braced by a jointed strut 9a, 10a. The strut 10a is connected at a point near the joint to a chain contained in a guide member 18a pivoted about a shaft 23 connected to two sprockets around which chains for the member 5a and its companion member are passed. The shaft 23 is connected by a flexible joint to a driving-shaft connected to the centrallyplaced electro-motor. The guide 18a is shown in Figs. 4 and 6 and comprises two tubes 43, 44 closely surrounding the chains, the tube 44 accommodating the free end of the chain as the undercarriage is raised. The tube 43 has guide strips 45, 46 closely engaging, the rollers of the chain and is slotted at one side to permit the passage of a pin 60 to the member 10a of the corresponding jointed strut. The pin 60 is on a block 61 connected by a link 59 to the end of the chain, the link 59 being longer than the chain links and being adapted to take up the position shown, when the undercarriage is extended, where it engages a surface 68 and locks the jointed strut in its extended position. The surface 68 is concentric with the pin 60 when the latter is in its completely lowered position. The slot through which the pin 60 moves has flexible weather-excluding strips 55, 56. A limit switch 76 is actuated to stop the motor when the undercarriage is extended, the end link at the free end of the chain being made longer than the others to permit a lever 78 to move inwards between adjacent rollers and out of contact with a plunger 77 connected to the switch. Should the motor fail, the undercarriages may be raised or lowered by a handle disposed at the front of the wing. Means for shortening the leg during retraction as described in Specification 567,749, [Group XXXIII], may be incorporated. A latch 80, Fig. 3, may secure the parts in their retracted position.
