Abstract
626,280. Stud-and-socket fastenings. ELECTROHYDRAULICS, Ltd., and LAWSON, D. T. Aug. 25, 1947, No. 23464. [Class 44] [Also in Group'XXXIII] In a retractable aircraft undercarriage the folding strut comprises a drag link 7 and radius rod 8, connected by a pivotal joint 9 carrying a locking member 15 which engages with a recess 12 in the undercarriage leg when the latter is lowered, so that the link 7 may absorb the landing loads. The member 15 consists of a short cylinder with opposed flats 16, 17 and is connected by a crank arm 18 to the lower end of the rod 20 of an auxiliary jack 21, pivoted at 23 to the link 7, the piston 22 of the jack being loaded by a spring 24. Near the end of the lowering movement the flat 16 engages a projection 14, thus rotating the member 15 against the spring 24 to allow its entry into the recess 12, after which the spring 24 returns it to the engaging position shown in Fig. 2. To release the catch, pressure is applied to the top of the piston 22 through a connection 25, to compress the spring 24 and rotate the member 15 to allow of its withdrawal from the recess 12, Fig. 4.
