Abstract

25,718. Kelvin & J. White, Clark, F. W., and Chetwynd, L. W. P. Nov. 8. Mariners' compasses. - In liquid compasses, the pivot pin 30 for the card is made easily removable, and is mounted for that purpose so as to be accessible from the exterior for unscrewing &c., and is arranged to pass through a partition 22 dividing the upper chamber 14 from the lower chamber 17, a sleeve 27, which surrounds it, preventing liquid at any time from passing from one chamber to the other. To obviate damage in transit, a guard is provided which protects the point and carries the card. Specification 19,057/09 is referred to.
