Abstract

13,846. Singleton, C. June 8. Instruction apparatus. - Apparatus for the self-teaching of semaphore signalling comprises a fixed disk marked, as shown in Fig. 1, with the letters &c. to be signalled, and two superposed rotatable disks, of which one has a number of apertures arranged in a spiral, and the other has a single radial slot. Each of the rotatable disks is provided with an index arm, and, when these arms are moved into the positions required for signalling a particular letter, that letter appears through the openings of the two disks.
