Entry
Model of an optical shutter telegraph with code table.
The telegraph consists of a square wooden board with five different sawn-out shapes that are set in one line and can be covered by sliding the wooden shutters vertically. Their movement is controlled by means of weights in the jambs at the sides.
The code table, drawn in ink, is supplied twice: once on paper pasted on to the bottom of the telegraph board, the other on a separate board, painted white. It shows the combinations of signs for the letters of the alphabet.
According to Obreen this telegraph is a British design.1
Scale unknown.
