    • An emergency flashlight for illumination or signalling comprising an abrasive member and a pyrophoric member. The abrasive and pyrophoric members are mounted for predetermined relative movement against each other to produce and project a stream of self-igniting particles of pyrophoric material abraded from the pyrophoric member. The position of the members and the direction of their relative movement is aligned to present the stream of particles to a light-transmitting combustion zone. As a flashlight, the device includes a reflector having a reflection or focal zone coincident with this combustion zone and constructed to beam the emitted light to the region to be illuminated. The reflector shields the eyes of the operator from the emitted light and from burning particles and, in preferred embodiments, is a uniform surface of revolution to provide a concentrated light beam. The reflector and abrasive and pyrophoric members can be protected by a transparent cover with the enclosed space vented to allow escape of combustion products and admission of oxygen. The pyrophoric member is preferably a rod adapted to be fed along its axis, as it is consumed, by a spring member, to engage the file-toothed rim of a rotating wheel that serves as the abrasive member. In the embodiments shown, the wheel is driven by a hand crank, an air motor and a battery-powered electric motor.
    • 用于照明或信令的应急手电筒包括研磨部件和自燃构件。 磨料和自燃构件被安装成相对于彼此预定的相对运动,以产生并投射从自燃构件研磨的自燃材料的自发粒子流。 构件的位置和它们的相对运动的方向被对齐以将颗粒流呈现到透光燃烧区。 作为手电筒,该装置包括反射器,该反射器具有与该燃烧区重合的反射区或聚焦区,并被构造成将发射的光束照射到被照射的区域。 反射器屏蔽操作者的眼睛与发射的光和燃烧的颗粒,并且在优选的实施例中是均匀的旋转表面以提供集中的光束。 反射器和研磨剂和发火构件可以被透明盖保护,封闭空间排空,以允许燃烧产物逸出并吸入氧气。 自燃构件优选地是适于沿着其轴线被馈送的杆,其被消耗的弹簧构件接合用作研磨构件的旋转轮的拱形齿缘。 在所示的实施例中,车轮由手动曲柄,空气马达和电池供电的电动机驱动。

    • A flashlight having side by side compartments for storage and a battery respectively. The battery compartment has partial dividers for confining the battery and leaving a space for a contact strip having a leg portion on which the battery sits. A snap in divider fits above the battery to hold a lamp, and the top of the contact strip is bent inwardly to make contact with the base of the lamp. Different color light transmitting caps can be put over the lamp so that the flashlight can be used for spectator voting or approval. Preferably different color caps can be kept in the storage compartment.
    • 手电筒分别具有并排室和电池。 电池室具有用于限制电池并且留下用于具有电池所在的腿部的接触条的空间的部分分配器。 分配器中的卡扣配合在电池上方以固定灯,并且接触片的顶部向内弯曲以与灯的基座接触。 可以将不同颜色的透光帽放在灯上,以便手电筒可以用于观众投票或批准。 优选地,不同的颜色帽可以保存在储藏室中。
