Abstract
26,329. Clarke, A., and Hedderwick, D. B. Nov. 28. Magnetic compasses to indicate the line of mark at night comprise a small pocket case containing a needle or floating card e, the head of the needle or the corresponding point on the card being coated with a strip of luminous paint e<2>. The case may be filled with spirit or other liquid. Over the needle or floating card is mounted a fixed and preferably opaque card d having the points of the compass marked thereon preferably with luminous paint, and extending from the centre of the fixed card to the north point is a radial slot d' through which the luminous needle or strip may be viewed when the compass is so held that the slot d<1> points to the north. Over the fixed card is revolubly mounted a hand or pointer f to indicate the line of mark; the surface of this pointer is coated with luminous paint, while its extremity has a opening f through which that point of the compass to which it is set may be viewed. The pointer f may be painted on the glass cover which is made revoluble, hinged front and back sights being provided on the ring supporting the glass for assistance in alining an object.
