MECHANICAL PANELS.
To make a double mechanical panel, that will open and close alternately, follow the device shown in the below diagram.
Cover the faces of the panels, or “doors” with cloth or puffing, and arrange them so as to cover two alcoves on opposite sides of the window. One cord is wound around the barrel and the other is unwound. When the barrel is turned, either by hand or by a motor, one door is raised while the other drops of its own weight, the doors being balanced by each other. The motion is reversed by reversing the barrel, or cylinder.
“A SCENE IN VENICE.”
The mechanical device called “A Scene in Venice” consists of a reproduction of the Trocadero palace, before which constantly passes a procession of floats or gondolas. The following diagram shows a ground plan of the framework of this window.
A procession of floats bearing dolls dressed as gondoliers, etc., passes constantly around the palace. The interior of the building was lit by colored electric lights. Six thousand handkerchiefs were used in this display, but the palace may be trimmed with linens or other goods.
