Abstract

367,165. Frictional pocket igniters. DAVIS, M., 42, Frederick Road, Edgbaston, and HEAPS, L., 21, Pitsford Street, Hockley, both in Birmingham. Feb. 7, 1931, Nos. 3928 and 6974. [Class 75 (iii).] The friction member 10 is mounted on a shaft 12 carrying an operating lever 48 and is provided with a roller or projection 27 engaging a plunger 26 slidable in a tube 24 containing a compression spring 23 so that, on depressing the lever, the spring is compressed and, on releasing the lever, rapidly returns the friction-member for igniting the wick 2. The lever 48 is formed with a top part 16 engaging behind a shoulder or projection on the member 10, or having a reduced end 17 fitting in a recess thereon, and preferably secured also to an enlarged part of the shaft 12 by means of a pin 20. The movement of the member 10 is limited by the projections 27, 29. A pivoted wick-cap carrier 31 is adapted to be held in either the open or closed position by a spring-pressed plunger 33 engaging a cam-shaped portion 35 and is moved into the open position by the projection 29 engaging the part 36 when the lever 48 is depressed. The wick is provided with a shield 38 having an extension 39 for directing the sparks from the flint. The base 40 of the reservoir 1 is covered by a plate 47 having apertures for the heads of the screw-plugs 41, 42, 46 for the filling opening, the spare flint container 43, and the flint tube 5 respectively. The first Provisional Specification describes also a construction in which the compression spring is arranged in a tubular sleeve and around a pin or rod pivoted to an arm on the friction member.
