ried on the reducedlower end of the ram, and is given 1-32-inch vertical play betweenthe cone seat and a winged nut on the extreme end of the ram.During the up stroke of the ram the lubricant thus has freeadmission past the conical seat to the under side of the piston;on the down stroke the cone and piston close up so as to pumpthe mixture past the non-return valve. On the lower cylindricalchamber an air cock is provided for use when starting up. There can be but very slight wear on the parts because theymove slowly and are always flooded with the lubricant. Becauseof the exposure of the device, arrangements have been providedto heat it by steam during cold weather through the pipe F,Fig. 1. Pure crystalline graphite only is suitable for cylinder lubri-cation. Amorphous graphite contains impurities which are difficultto eradicate and make it entirely unsuitable for the purpose.Even the crystalline graphite must be carefully refined to givesuccessful results. 476 LOCOMOTIVE APPLIANCES.
