Abstract

22,933. Ogilvy, J. W., [Leitz, E.]. Oct. 17. Field glasses.-To facilitate adjustment, the prism-carrying tubes 4, which are supported between plates 1, 2 hinged at 3, are provided at each end with cover-plates 9, into apertures in which the casings 6, 8 carrying the object-glasses and eyepieces are screwed. The cover-plates 9 are held against the end plates by screws 10, 11 engaging loose plates 13, as shown. The holes 12 in the plates 9 and the apertures 5, 7 in the plates 1, 2, through which the screws 10, 11 and casings 6, 8 pass respectively, are made larger than is necessary so that by loosening the screws &c. adjustment is readily possible.
