Abstract

615,400. Hydraulic operating jacks. CONWAY, H. G. Aug. 13, 1946, No. 24068. [Class 69 (ii)] [Also in Group XXXII] A combined hydraulic jack and shock-absorber for aircraft undercarriages comprises a tubular body 11 divided in two by a diaphragm 12 into two chambers 13 and 14. The chamber 13 contains a piston 21 with a tubular piston rod 22 having a connecting eye 24. The interior of the rod 22 is divided by a piston 25 into an air chamber 26 and a liquid chamber connected through a disc valve 31 to the chamber 13. Chamber 14 contains a piston 15 connected to a tubular piston rod 16 in such a manner as to allow limited movement of the piston 15 thereon. A crown of claws 42 is fixed on the exterior of the body 11 and in the fully retracted position of the piston 15 engages the rim of a locking collar 43. A locking ring 57 having a shoulder 50 of larger diameter than the body 47, slidably mounted on the rod 16 and pressed away from the collar 43 by a spring 49, passes inside the crown 42 to lock it to the collar 43. A cross-head 55 projecting through and slidable in slots 56 in the rod 16 is fixed to the ring 57 and connected to a rod 52 which bears against the end 53 of the piston 15 to disengage the crown 42 when pressure is admitted on that side of the piston 15. Specifications 527,225 and 615,401 are referred to.
