    摘要： A safety igniter for flares is attachable to the flare parachute by a lanyard that operates the igniter when the parachute opens. The igniter is packaged in a housing that is mounted into the flare casing adjacent the ignition surface of the flare candle. The housing has two contiguous bores of different diameters, the larger bore containing a primer-charge holder and a firing-pin holder, both of which are movable in the bore. The primer-charge holder is retained adjacent the shoulder at the juncture of the bores, so that its motion is rotational only; while that of the firing-pin holder is primarily a forceful axial motion produced by the parachute lanyard, to which it is operatively attached. The primer charge is normally out of angular alignment with the firing pin and the chamber in the housing containing a pyrotechnic charge, but is aligned with a dead-air chamber. However, means for rotating the primer-charge holder is actuated in response to axial motion of the firing-pin holder, so that the primer charge is brought into alignment with the firing pin and pyrotechnic charge before it is struck by the firing pin. In one embodiment, all three of these items are normally mutually out of angular alignment, so that the firing-pin holder must also be rotated. When the firing pin strikes the primer charge, it discharges into the pyrotechnic material which, in turn, discharges hot gases onto the ignition surface of the flare candle.

    摘要翻译： 闪电的安全点火器可以通过在降落伞打开时操作点火器的挂绳连接到火炬降落伞上。 点火器被包装在与火炬蜡烛的点火表面相邻的外壳中。 壳体具有两个不同直径的连续的孔，较大的孔包含底座充电保持器和击打针保持器，它们都可以在孔中移动。 底座电荷保持器在孔的接合处保持在肩部附近，使得其运动仅旋转; 而射针支架的主要是由降落伞系绳产生的有力的轴向运动，其可操作地连接到该轴向运动。 底漆装料通常与打击销和包含烟火装料的壳体中的腔室成角度对准，但是与死气室对准。 然而，响应于点火针保持器的轴向运动而致动用于旋转底漆充电保持器的装置，使得底漆装料在撞击销被撞击之前与撞针和烟火充电对齐。 在一个实施例中，这些物品中的所有三个通常都相互偏离角度对准，使得击球针座也必须旋转。 当撞针撞击底漆时，它会排放到烟火材料中，然后再将热气体排放到火炬蜡烛的点火表面上。

    摘要： A watertight and corrosion-resistant percussion igniter has a housing, a percussion cap in the housing and a firing pin mounted in the housing and having a free end spaced from and adapted to impact the percussion cap. A one-piece tubular holder surrounds the firing pin and has at least one transverse hole, and a retaining member is located in the hole and engages in a depression formed in the firing pin. A biasing spring biases the firing pin towards the percussion cap and makes the free end of the firing pin impact the cap when the retaining member becomes disengaged from the depression so that the firing pin can move relative to the tubular holder.

    摘要： MANUALLY-CONTROLLED FIRING MEANS HAVING A STRIKER WHICH IS SLIDABLE IN A BODY AND CAPABLE OF STRIKING A PRIMER UNDER THE EFFECT OF A SPRING. STOP MEANS ARE PROVIDED ON THE STRIKER AND AN ARM PIVOTED TO THE BODY CO-OPERATES WITH THE STOP MEANS FOR HOLDING THE STRIKER AWAY FROM THE PRIMER. A LEVER PIVOTED TO THE BODY IS CAPABLE OF ACTING ON A POINT ON THE ARM SO AS TO TURN THE ARM ABOUT ITS PIVOT AND STRESS THE SPRING AND THUS ARM THE STRIKER UNTIL THE ARM DISENGAGES FROM THE STOP MEANS AND RELEASES THE STRIKER.
