| 201 | Firing Mechanism for a Grenade, a Grenade and a Method of Operating a Grenade | US15572057 | 2016-06-06 | US20180135954A1 | 2018-05-17 | Duncan Thomas |
| A grenade firing mechanism (12) includes a body (24) containing a firing pin (20) and a tiring pin actuator mechanism (22). A safety system includes twist to arm collar (70) and a safety interlock (92). The collar is movable between an unarmed position and an armed position and tire safety interlock is movable between a collar locking position, a collar release position and a firing position. When the collar (70) is in the unarmed position and the safety interlock (92) is in the collar locking position, actuation of the firing pin (20) is inhibited and the safety interlock (92) inhibits movement of the collar to the armed position. When, the safety interlock (92) is in the collar release position, the collar (70) is able to be moved between said unarmed and armed positions and actuation of the firing pin is inhibited. When the collar (70) is in the armed position and the -safety interlock (92) is in the firing position, actuation of the firing pin is enabled. | ||||||

| An explosive device contains a water-reactive material that ignites upon exposure to water. The water-reactive material ignites a water-activated fuse that has a predetermined burn rate and length. The predetermined burn rate and length allows the device to sink to a desired depth before exploding. Hence, the device explodes after a desired period of time and/or at a desired depth. Defense against underwater swimmers is an advantageous feature of embodiments of the disclosure. The device can use a forty millimeter (40 mm) form factor, which permits launch of the device from convention grenade launchers. | ||||||

| 211 | DIVERSIONARY DEVICE | US14790352 | 2015-07-02 | US20150308801A1 | 2015-10-29 | Duncan THOMAS |
| A diversionary device has a housing containing a pyrotechnic cartridge with an ignitable fuse. A firing arrangement includes an ignition cap containing a primer charge. Passageways in the housing and ignition cap define a first flow path from the primer charge to a region of the housing in which the fuse is located through which flash from the primer charge can flow to ignite the fuse. A further flow path connects said region of the housing with the exterior of the housing to supply the fuse with oxygen for reliable burning. The device may be a multi-burst device containing a plurality of cartridges and the first flow path may include a flash divider for directing a proportion of the flash from a primer charge on to the fuse of each cartridge. The housing may be separable to allow replacement of the cartridges. | ||||||
| 212 | Projectile interceptor mountable on a firearm | US14515486 | 2014-10-15 | US09170074B2 | 2015-10-27 | Christopher V. Beckman |

The detonator is associated with the detonator initiating mechanism. The locking key interacts with the detonator initiating mechanism to preclude an arming of the detonator until the locking key is removed from the detonator initiating mechanism. The locking key has at least one notch therein. | ||||||
| 215 | Fuze pull pin detent device | US14037920 | 2013-09-26 | US09010250B1 | 2015-04-21 | Matthew P. Evangelisti; Steve Kotefski; Lidija Kotevska |
| A grenade fuze assembly includes a fuze body and a striker lever fixed to the fuze body with a pull pin. A circular pull ring is attached to the pull pin. A detent device is disposed on a top portion of the fuze body and a top portion of the striker lever. The detent device includes four sides with a boss formed on an exterior of one of the four sides. The boss includes a curved slot for receiving and holding the pull ring. A pair of opposed locking tabs on opposite interior sides of the detent device engage the top portion of the fuze body. The detent device secures the pull ring to prevent accidental removal of the pull pin when the grenade is dropped and to prevent undesired noise cause by movement of the pull pin and pull ring. | ||||||
| 216 | Pressure discharge mechanism for closed vessels | US13623843 | 2012-09-20 | US08997773B2 | 2015-04-07 | Stojan Kotefski; Eugene R Reda |
| The present invention relates in general to a pressure discharge mechanism for closed vessels having an internal chamber designed to hold volatile and/or explosive substances in a sealed manner comprised of an at least one eutectic composition and a threaded joint designed to open or vent the closed vessel when the contents of the closed vessel reaches a predetermined temperature while maintaining full structural integrity during normal operation. In one aspect, the closed vessel is a munitions casing which functions as intended under normal operating environments, but then when exposed to extreme temperatures, reduces the munition's high order explosion capability, and is transformed into a safe, low order reaction with significantly less reactive potential. In one aspect, the closed vessel is a transport tanker which should not release substances contained therein. However, if the tanker catches fire, the pressure relief mechanism of the present invention reduces risk of explosion. | ||||||

| 218 | Grenade with time delay | US13554151 | 2012-07-20 | US08904940B1 | 2014-12-09 | Sokha Pann; Samuel R. Koski; John F. Busic |
| A grenade device produces a delayed bang upon coupling to a pressurized canister containing gas. The device includes an annular housing, an awl, a sleeve, a diaphragm, a base and a cap. The housing has first and second axial ends and an internal bulkhead disposed therebetween with a choke flow-through orifice. The awl extends axially outward from the bulkhead. The sleeve connects to the housing at the first axial end. The diaphragm is disposed between the sleeve and the housing to form an annular chamber. The cap inserts into the housing at the second axial end and receives the canister facing the awl. The base connects to the housing at the second axial end. When the canister is compressed towards the device the awl punctures the canister to release the gas, which flows through the choke orifice to pressurize the chamber, and the diaphragm ruptures upon exceeding a pressure threshold. | ||||||

| A stun grenade is provided with a housing; al receptacle including a bottom hole and a hollow externally threaded member; an air canister in the receptacle; an internally threaded cap including a top opening and a top bifurcation including two opposite through holes in an intermediate portion, and two opposite first pivot holes in a rear portion; a striker unit including a striker and a spring loaded hinge pivotably fastened between the first pivot holes; a needle inserted through the hollow externally threaded member to have one end engaged with the air canister and an other end projecting out of the top opening; a lever having a front end pivotably secured to a front end of the bifurcation and including two opposite second pivot holes at an intermediate portion; and a safety pin inserted through the second pivot holes and the through holes to anchor the needle below. | ||||||
| 220 | Electro-mechanical fuze for hand grenades | US13608494 | 2012-09-10 | US08887640B1 | 2014-11-18 | Ryan R. Knight; Oliver M. Barham; Thinh Q. Hoang; Robert H. Wood |
| A safety fuze includes a magneto striker generator (MSG) as its a power generation source. The MSG provides energy to energize an electronic unit and a safety and arming device. The safety fuze allows safety and arming of military hand grenades, with a fully out-of-line explosive initiator and an integrated power generation means, for improving safety and performance. The MSG includes a striker and a receiving bobbin that houses a conductive coil. The striker comprises a permanent magnet that is mounted on a pivot mechanism for allowing a rotational displacement of the permanent magnet, into the bobbin, in order to generate an electrical current. As the permanent magnet is being inserted inside the bobbin, the magnetic flux change induces an electric current in the coil, creating the necessary energy for the fuze operation. | ||||||
