Abstract

1,196,563. Rocket launcher. NORRIS INDUSTRIES Inc. 13 Feb., 1968, No. 7135/68. Heading F3C. A rocket launcher comprises two telescopic sections 10, 11 one 10 of which forms the breech end of the rocket launcher. The section 10 has a rigid member 20 attached thereto which member 20 overlies the section 11. A firing mechanism comprises a firing member 34 which is movable relative to the section 10 between a cocked forward position and a firing position. The cocking is effected during extension of the sections 10, 11 when the rigid and firing members 20, 34 are interconnected for movement with the section 10 by a pivoted latch 42. Towards the end of the extension movement of the two sections the firing member 34 is releasably connected to a trigger 22 so that the firing member is locked to the section 11 and a cocking spring (Figs. 1, 9, not shown) is compressed. A safety 30 is movable to disengage the latch 42 from the members 20, 34. In the construction shown the firing member is provided with a firing pin portion which cooperates with an igniter mounted in a pocket of the section 10. The latch is urged in an anticlockwise direction by one end of a spring 46, the other end thereof engaging a lock 47 which locks the sections in their telescoped conditions. The rocket launcher is shown as adjusted to discharge subcalibre rockets. To this end a tubular member 74 is mounted in the section 10 by three discs 75 (Fig. 9, not shown), 76, 77. The disc 75 includes an electric terminal for firing the rocket, the impulse being generated by a magneto 91 mounted on the disc 75. The magneto 91 which comprises a spring-loaded, slidable actuator 92 is actuated through a linkage 102, 103, 99 by a part 106 depending from the firing member 34. A lost motion connection is provided between the rod 102 of the linkage and the depending part 106 such that the part 106 is accelerated before it engages the rod in its firing stroke. A firing impulse is not imparted to a rocket in the launcher on cocking of the firing mechanism as the output of the segments is earthed through a switch 112 which is controlled by an arm 113 of the latch 42. A foresight and a backsight 51 are folded within the rocket launcher in the telescoped condition thereof but are spring-loaded to an erect position on extension of the rocket launcher.
