Abstract

18,116. International Oxy-Generator Syndicate, and Rosenberg, A. Aug. 21. Telescopes.-A flash signal lamp, a search-light, or other optical lantern may be employed, when not used as a lamp, as a telescope for sighting distant objects and for facilitating the alignment thereon of the beam emitted by the lantern. In the flash signal lamp shown in Fig. 1, a removable and adjustable eye piece A is provided in the back b of the lantern in alignment with the main lens C. Perfect alignment may be facilitated by the provisions of a pointer, cross-wires, or other sighting- index. When the eyepiece A is removed, the aperture is closed by a pivoted flap. In a searchlight in which, instead of a front lens C, there is a reflector at the back of the lantern, the eyepiece is adjustably and removably inserted through an aperture in the reflector or in the side wall of the lantern, and an additional smaller and removable reflector is provided.
