IPC: F42C9/02
Filed: 1917-08-16
Abstract: 128,631. Keeson, H. V. Cuthbert-. Aug. 16, 1917. Projectile fuses.-Relates to mechanical time or distance fuses of the kind described in Specification 18664/10, and consists mainly in providing means whereby the vane member will be thrown out to the operative position only when the projectile is beyond the gun-blast, and will be steady and non-revolving from the start. Fig. 2 shows the initial condition of the parts, which comprise two vanes or blades 4 connected to a piston 1 by a swivel 3 and joined at their front ends by a weight 5 which rests on the forward end of the fuse body. The vanes are ejected, as described ir. the above-mentioned Specification, by the action on the piston of gases from a charge 8; but, in order to delay this action, a spring 9 and an inertia plunger 7 with pawls 10 for gripping the cartridge are provided. The rebound of the spring carries the cartridge forward against a needle 31 after the spring has been compressed by the set-back of the plunger 7 on discharge of the projectile. The non-circular axial spindle 12, which is caused by the vanes 4 to rotate relatively to the fuse-body, has a pinion 13 geared by a train of wheels (not shown) to a toothed ring 19. This ring has a flange 20 provided with a slot 21, Fig. 1, into which, at a moment predetermined by the setting, the heel of a trigger 22 passes. This movement allows the weighted end 23 of a pivoted centrifugal hammer 24 to move out tangentially, so that its other end 25 strikes a percussion cap. The flash that is produced passes into a circular groove 28 at the rear of a turret 27 upon which the parts 22, 24 are mounted, and thence passes to the magazine of the fuse. The turret 27 can be rotatably moved with respect to the flange 20, by connexion with the dome of the fuze. To set the fuse for action by percussion only, the time mechanism is adjusted to the extreme range. The percussion inertia pellet 42, Fig. 7, is normally secured by its tail screwing into a wheel 41, which is geared to the axial spindle 12 and is rotated thereby during flight so as to unlock the pellet.
