    • 446,092. Frictional igniters. ASPREY, K. M. F., 89, Wigmore Street, and CAMPBELL, A. H., 2, Hanway Place, Oxford Street, both in London. Oct. 16, 1934, No. 29601. [Class 75 (iii)] The friction-wheel 14 is connected by a one-way spring-pressed clutch pinion with a rack 26 on a spring-pressed operating slider 20 carrying a wick-cap 32, the parts with the wick-tube 19 being mounted in a removable metal container 13 in the top of a fuel receptacle 10 made of the material known by the Registered Trade Mark " Bakelite." The movements of the slider 20 are limited by a slot therein engaging a pin 23. The container 13 is closed by a metal cover (not shown), having a flame-emission aperture, air inlet openings being provided through the parts 10, 13. In the table lighter shown, the receptacle 10 is provided with feet 11 and recesses 21, 18 for the reception of the slider 20 and the screw-cap on the flint tube 17. As shown in Fig. 5, the one-way drive for the friction-wheel comprises a pinion 27 operated by the rack 26 and carrying face teeth 30 engaging, under the influence of a spring 28, with face ratchet teeth 29 on the friction-wheel. According to the Provisional Specification, the drive may be a pawl on the slider engaging a ratchet pinion connected to the friction-wheel. Reference has been directed by the Comptroller to British Specifications 138,395, [Class 75 (iii)], and 395,809, and U.S.A. Specifications 1,831,014, 1,859,908, and 1,966,914.
