Abstract

859,228. Self-propelled missiles; missile launching supports. SHORT BROS. & HARLAND Ltd. Nov. 2, 1959 [Jan. 22, 1959], No. 2489/59. Classes 9(1), 9(2) and 92. A missile launching support comprises a beam 13 for suspensory attachment to the missile 12 and adapted to be mounted on a launcher platform, a link 16 for connecting the after end of the missile to the rear end of the beam and incorporating a shear pin 22, a latch 23 pivoted on the link and movable to a safety position, Fig. 2, in which the tensile and/or compressive loads in the link are taken by the latch and bypass the shear pin, a locking member 26, normally adapted to lock the latch in the safety position by an abutment 27 on the latch and a spring loaded plunger 31 housed in the beam 13, and released by the depression of the plunger 31 by a fixed pin (not shown) on the launching platform, to free the latch when the missile is positioned on the launching platform ready for firing. A sprung ball catch 33 engages recesses in the latch to retain it in the locked and inoperative positions respectively. The latch has a hook portion 24 to engage a concentric enlargement on the part 20 of the link, and is pivoted on an eccentric pin 29 which is adjustable to take up any clearance between the hook and the enlargement. On firing, the blast from the missile rocket motor reacts against a palm member 28 on the latch, rotating the latch so that the hook is disengaged from the link and the thrust of the motor severs the shear pin 22. During stowage the tensile loads between the missile and a base plate 14 on the launching platform are taken by an adjustable screw 34 in the rear end of the link, thereby pulling the missile against a pad 35 and relieving the shear pin. Specification 843,038 is referred to.
