Not illustrated. 1907 Excerpt: ...than just clean the pointed ring. And here let me remark that the practice of scraping the dirt from the plug with a knife or other hard implement should always be avoided, because it will be found to damage the enamel, leaving the porcelain rough so that it will more readily hold any deposit. A plug that has been cleaned in this manner will often be found to become dirty again in a very short time. For this reason, and in order to lessen as much as possible the chances of deposit getting upon the plug, there are several types in which it is sought to protect the nose of the porcelain as much as possible. The main portions are of the usual type, but the porcelain is recessed at the nose to receive a small asbestos washer J, and the wire E Ex terminates in a metal bell, as shown. It passes through the porcelain B, and over the end Ei is passed another washer F, held in position by the nut G. This nut holds the wire in place, and the washer J renders the joint completely tight. This plug has this advantage that, by removing the wing nut H and the nut and washer G and F, the wire can be completely removed from the porcelain, leaving the nose of the latter perfectly free, as the small washer J will usually come off as the wire is withdrawn, but if it does not do so, it is easily removed while the porcelain is out of position. In place of the ordinary sparking points the sparks occur at any point round the mouth of the bell and between it and the base A. The distance at which the bell is set from the base can be regulated by the thickness of the washer J, but it should never be very great. A sixty-fourth of an inch is ample, and very often ignition may fail owing to the distance being too great. This applies equally to the setting of the points of the more ordin...
