Abstract: 1,205,389. Grenade launcher. COLT'S Inc. 17 March, 1969, No. 13763/69. Heading F3C. A grenade launcher 10 comprises a cylindrical barrel housing 12 having a cartridge loading opening and a movable bevel 14 concentrically positioned within the barrel housing. A hand grip 146 is mounted on the barrel 14 for moving it between a loading/unloading position and a locked firing position in which positions the loading opening is open and closed respectively. A trigger assembly 168 is housed in the barrel and co-operates, in the firing position of the launcher only, with an actuating drive member 108 of a firing mechanism 38 fixed in the housing 12, the trigger assembly 168 being automatically disconnected from the actuating drive member 108 during the cartridge loading and unloading operations. In the construction shown the firing mechanism 38 comprises a casing 42 housing a spring-loaded striker 62 having a return spring 76 associated therewith and a rotatable sear 86 pivotably mounted on a pair of supporting arms 100. The upper ends of the arms 100 are pivoted in the casing 42 and the lower ends co-operate with the actuating driving member 108 which comprises a rectilinearly movable yoke through a cross-pin 106. On actuation of the trigger assembly 168 an extension 172 thereof urges the driving member 108 rearwardly such that the sear, at this time engaging an annulus 72 on the striker 62, draws the striker rearwardly against its spring loading. The sear 86 is provided with a pair of rearwardly extending arms 96 (98, Fig. 9, not shown) so that, after an initial rectilinear movement of the sear 86, the arms engage the internal rear wall of the casing 42 to pivot the sear 86 and thus release the striker 62. After the trigger assembly 168 has been released the sear 86 is urged forwardly by a spring 112 into its annulus engaging position. The barrel and handgrip assembly is held in its rearward firing position by a locking lug 134 of the assembly engaging the rear face 136 of an arcuate segment 132 of a firing mechanism recoil plate 56 and latched in this position by a spring-loaded catch 142. To move the barrel into the loading/ unloading position the catch 142 is actuated and the barrel and handgrip rotated approximately 40 degrees (Fig. 4, not shown) whence relative guided movement can then take place between the barrel and housing. The firing mechanism is provided with a spring-loaded extractor 57 and the barrel slides in the housing through surfaces 160 of a bearing sleeve 158 in the housing and projections 164 on the barrel. A mount for attaching the launcher to a smallarm comprises a ribbed metallic heat shield of arcuate section for engagement with the barrel of the small arm and an insulating liner of a plastics material interposed between the mount proper and the heat shield (Fig. 7, not shown). A manually releasable cross-bolt safety 190 is provided.

Abstract: 378,427. Controlling change-speed gearing; claw clutches. LJUNGSTRÍM, B., 83, Linnegatan, Stockholm. May 9, 1931, No. 13783. Convention date, April 1. [Class 80 (ii).] Selector control mechanism for claw clutches in changespeed gearing for vehicle comprises spring mechanism built into the selector mechanism itself. Toothed clutches 21, 22, 23, Fig. 1, and a gear 27, are engaged by the operation of forks 24, 25, 26 secured respectively to recessed blocks 28, 29, 30, Fig. 2, fast on sliding selector bars 32, 33, 34. A selector arm 37 adapted to engage the blocks 28 &c. alternatively is secured to a piston 38 slidable within a tube 40 which can slide and turn in fixed bearings 39. The arm 37 projects through a slot 41 in the tube 40 so that when the latter is turned by a control lever (not shown) the arm turns with it between the blocks 28 &c. to effect selection. The piston 38 has a hole 42 at each end containing each a spring 45, 46 and closed by a cap 43 screwing into the piston. The outer ends of the springs 45, 46 abut on discs 47, 48 having projecting stems 49, 50 resting against abutments 51, 52 fast inside the tube 40. To effect the striking movement of the selected block 28 &c., the tube 40 is moved longitudinally by the control lever to its final position. If the teeth of the selected clutch are not in position to engage, the fork 28, arm 37 and piston 38 are suffered to lag behind by the compression of one of the springs 45, 46, which asserts itself later to follow up, when the clutch teeth slip into mesh. The change-speed gear shown comprises a dental clutch of the form shown in Fig. 3 in which internal teeth 23 in a circle of relatively large diameter are coned on their outer edges to engage with the coned ends of the gear teeth of a loose sliding gear 18. Friction produced at the coned surfaces by the spring 46, Fig. 1, produces synchronism, after which the clutch teeth slip in.
