Abstract: 10,457. Kellermann, J. April 28. Pocket igniters, catalytic and frictional.-A lighting-appliance comprises means for supplying liquid fuel, frictional or other means for effecting initial ignition, and a catalytic mass to maintain incandescence after the initial ignition. The invention is described as applied to pocket igniters. In one form, Fig. 1, the burner of a spring-lid pyrophoric pocket igniter is provided with an ordinary wick 5, and with an incombustible tip 6 of asbestos or the like, impregnated with a catalytic substance such as platinum. When the combustible, preferably petrol or benzene, is ignited by pyrophoric means at the wick 6 and then goes out or is blown out, the wick 6 continues to glow by catalytic action, but does not suck up sufficient fuel to maintain a flame. The following modifications are described:-(1) The catalytic wick is arranged in a separate wick-tube adjacent to the main wick-tube, and may be provided with a separate fuel-reservoir. (2) The catalytic wick is adjacent to or encircles the ordinary wick and draws its fuel therefrom. It may be carried by an annular holder 14, Fig. 5, fitted or screwed on the wick-tube 10<1>; or it may be of a coherent. material such as kieselguhr laid round the wicktube. (3) A pellet 18 of spongy platinum or the like, Fig. 7, is arranged on the wick 19 of an igniter in which the friction wheel 16 is rotated by hand. To support the pellet, and to prevent it from soaking up too much fuel, it is enclosed in one or two wire nets 20, 21. The wick 19 may be incombustible, or of less absorbent material than cotton. (4) The catalytic pellet 22, Fig. 8, is supported over the wicktube 27 by a yoke 23 clipped on the holder 25 for the pyrophoric device. The lower part of the pellet is tubular and makes contact with the wick. (5) The catalytic pellet 29, Fig. 10, is fitted on the wick-tube 28 by means of a sleeve perforated at one side or made of wiregauze. (6) The catalytic pellet 35, Fig. 11, is carried by a U-shaped hood 34, which may be made of wire net and is secured over the wicktube by a ring 37. The pellet has perforations 36, which allow the passage of fuel and serve for attachment to the hood by means of wires. The hood 34 may be replaced by a perforated disk or wire netting, the pellet and disk &c. being secured to the wick by means of a pin or spike. (7) A torch 39, Fig. 14, has a wick 41 and a striking-pin 40, over which an annular pellet 42 or a catalytic wick is fitted. The pin 40 is struck on the friction surface of a fuel container. The pellet 42 is separated from the wick 41 by a wire net 43, and may be protected by a wire cap 44, or by lugs on the end of the torch tube. The pellet or the like may be at the side of the wick 41, especially if the sharp edge of the torch tube is used as the striker. (8) The pellet 45, Fig. 17, is arranged on a lever 46, which moves away from the wick when the lid 47 is closed. (9) The pollet 50, Fig. 18, can be moved about a hinge 51 into the position indicated in dotted lines. (10) The pellet 52, Fig. 19, is mounted on a cap 53, which can be placed over a projection 55, or over the wick-tube when not in use. (11) The pellet 58, Fig. 21, is mounted on a spring arm 57 on a frictional torch 56, the arm 57 being received by a separate tube 60 in the fuel container. When the torch is withdrawn for use, the pellet 58 is brought into contact with the wick of the torch by pressing the spring arm 57. (12) An annular pellet 62, Fig. 23, is displaceable on the torch 61. When the torch is placed in the fuel container, the pellet is engaged by a shoulder 66, and when the torch is withdrawn, the pellet is pressed forwards by the spring 63 into engagement with the end 64 containing the wick.
