Then the part A B, hidden in the room below, forms one with the part C D, within the figure, and the two united become the end of the pantograph.
Performance.—All the drawing done by the assistant unseen must be repeated at the point K. Now, the pantograph being within the body of the automaton, and setting its arm in motion, it seems as if it was drawing of its own volition.
Fig. 156.
Observation.—The needle A B, and the cylinder C D, when in junction, form a kind of lever with its fulcrum in the room below, and, consequently, all the movements given to the point B are first repeated in miniature at B of the pantograph in reverse, and then large at A.
THE AUTOMATON PERFORMER ON THE HORIZONTAL BAR.
Make a puppet with its arms inflexible at the elbow; put on a ball-and-socket joint at the shoulder; the arms are bent as shown in the illustration.
At the points G H and L M on the bar are tubes, covering it; with the joins hidden by mock garlands of flowers; the tube can, however, enter the two supports. To this tube the figure is fastened by the forearms.
