| 41 | Projectile fuze operated by a stabilization band of the projectile | US09551616 | 2000-04-17 | US06405652B1 | 2002-06-18 | Wolfgang Hoffmann; Michael Günther; Tobias Zerbe |
| A projectile includes a stabilizing band mounted on a rear projectile portion and having a folded state and a deployed state and a fuze assembly accommodated in the projectile. The fuze assembly includes a firing pin carrier supported for motion parallel to the longitudinal axis of the projectile; a firing pin secured to the firing pin carrier; a slide supported for motion transversely to the projectile axis and having a safety position and a firing position; and a detonator mounted on the slide. The detonator is out of alignment with the firing pin in the safety position of the slide and is in alignment with the firing pin in the firing position of the slide. A force-transmitting component is attached to the stabilizing band and the slide for moving the slide from the safety position into the firing position by a force generated by a motion of the stabilizing band from its folded state into its deployed state. | ||||||
| 42 | Automatically releasable safety device used in mechanical igniter for gas generator | US182594 | 1994-01-18 | US5507523A | 1996-04-16 | Muneo Nishizawa; Tetsuya Hamaue; Mitsuhiko Hiruta; Koji Hiramatsu |
| A mechanical igniter for a gas generator has a weight, a latch lever and a firing pin as movable elements to fire a percussion cap attached to the gas generator in response to acceleration, and further has a restraint member and a controller therefor as a safety device for making the movable elements immovable. The controller can be activated by attaching the mechanical igniter to the vehicle body, or removing a belt stopper after the mechanical igniter has been attached to the vehicle body, or fastening a seat belt to the occupant's body. Thus, the restraint member is released when the mechanical igniter is attached to the vehicle body, or when the seat belt system is used, thereby automatically and safely releasing the safety device for the igniter. | ||||||
| 43 | Firing mechanism for projectiles | US516405 | 1983-07-22 | US4526105A | 1985-07-02 | Thomas W. Herren, Jr. |
| A firing mechanism for projectiles comprises a housing (42) having a bore (50) in which a firing pin (54) is slidably mounted under the influence of a spring (70). Leaf springs (72) formed in the housing wall hold the firing pin in a safety position until released by movement of a slider (82) caused by aerodynamic drag forces acting on deployable fins (96) or a parachute (92). | ||||||
| 44 | Safety ring/firing pin for explosive device | US432588 | 1982-10-04 | US4487128A | 1984-12-11 | Peter H. Van Sloun |
| A firing pin/safety ring for a portable explosive device characterized by the firing pin being positionable in a wide range of angular positions with respect to the plane of the safety ring. | ||||||
| 45 | Fuze safety device | US300543 | 1981-09-09 | US4430938A | 1984-02-14 | Ulf Jander |
| The invention relates to a fuze safety device (1) for an ammunition unit such as a projectile, shell, rocket or the like. The safe and armed conditions of the fuze safety device are defined by a movable slide or rotor member which takes a first position in safe condition and a second position in armed condition and cooperates with at least two locking elements (7, 8). Each locking element has its own condition for release and in their released positions they permit the movable member to assume its second position. The locking members (7, 8) are arranged to cooperate mutually in such a way that both of the locking elements are released when their release conditions occur in a first order but release of at least one of the locking elements is inhibited if release conditions occur in a second order. | ||||||
| 46 | Rotary locking mechanism | US60557 | 1979-07-25 | US4296689A | 1981-10-27 | Thomas K. C. Hardesty |
| A mechanism for immobilizing an arming shaft to preclude axial movement ofhe shaft until its release is desired, comprising a base and rotor mounted thereon. The rotor holds hardened metal balls in engagement with a circumferential groove on the shaft to lock the shaft in position. The base, rotor and shaft are held in locked position by an arming wire. Compression springs acting between the base and rotor cause relative rotation thereof, when the arming wire is removed, to an unlocked position where the balls can be forced into apertures in the base and release the shaft for axial movement. | ||||||
| 47 | Latch devices | US44159 | 1979-05-31 | US4286522A | 1981-09-01 | Brian T. Trayner |
| A latch device in which movement of a shutter from a first to a second position is controlled by two latches in turn controlled by separate timers, the arrangement being such as to prevent the shutter reaching the second position unless the latches are operated in the correct sequence and the time between operation is above a nominal small value. | ||||||
| 48 | Safety and arming mechanism | US45899954 | 1954-09-28 | US3877378A | 1975-04-15 | CLARK FITZHUGH T; THEODORE DAVID T |
| 1. In a fuze for an explosive projectile having a base section, a body section, and a nose section, a safety and arming mechanism including a firing train having a booster charge and acceleration-sensitive means for initiating fuze arming when the projectile to which the fuze is affixed is fired from a gun, the improvement comprising: an impact assembly located in the nose portion of the fuze, said impact assembly comprising a cartridge containing a dust under pressure, means for releasing said dust from said cartridge after the projectile to which the fuze is affixed is airborne, the action of the dust passing over the projectile serving to deposit an electrostatic charge upon the projectile.

| 49 | Hand grenade trigger safety lock | US41110873 | 1973-10-30 | US3823670A | 1974-07-16 | ZACHARIN A |
| The present invention relates to a safety device for conventional hand grenades. The safety device comprises a double headed cotter pin which is automatically locked in a safe position by the lever handle and can be removed by the thrower, when desired, to arm the grenade.

| 50 | Explosive-disseminator package | US3744425D | 1971-10-29 | US3744425A | 1973-07-10 | GRIMM R |
| A package for the explosive-dissemination of material, e.g., chaff, is described herein as an embodiment of the invention. This package includes a safe-and-arm mechanism which prevents detonation of the explosive during transport and loading, and in the event of malfunction during the dispensing of the package. During normal operation, the fuze assembly must be unlocked and transferred to a first position for the initiation of the primer and pyrotechnic delay. Once the package clears the package dispenser, the fuze assembly is moved to a second position where the pyrotechnical delay becomes aligned with the detonator for the explosive.

| 51 | Bomblet fuze system | US3646889D | 1970-07-09 | US3646889A | 1972-03-07 | DAVIS EDWARD J |
| A bomblet fuze arming device for use inside a bomblet which is dispensed from a container by a remote means; the device utilizes gas or air pressure to compress an enclosed cavity of air which in turn unlocks a stab-detonator holder and during release from the bomb dispenser performs the arming function by use of a reaction turbine, which locks at the end of the arming function.

| 52 | Self-dudding ordnance fuze | US3601059D | 1969-09-17 | US3601059A | 1971-08-24 | BRIGGS GEORGE S |
| An ordnance fuze having a selector rotor and an arming rotor initially held in an unarmed position by a rod which can be released by the rotation of a wind vane to move clear of the arming rotor and thus free the arming rotor to rotate to an armed position. A timer revolves a plate to block the movement of the rod after a predetermined time lapse if the vane has not already released it, thus preventing the arming of the fuze. An externally operated control limits the movement of the rod to either permit or prevent rotation of the selector rotor to direct the blast of the primer to either an instantaneous detonator or a delay detonator.
