The glass case used in this act is made to order, and is quite expensive, being made of one-quarter inch glass on the sides and top, and three-eighths inch glass on the bottom. All this has to be drilled to take the bolts for the corner angles and hinges. The case, as it appears on the stage when closed and locked, is shown in Fig. 1.

The sides "A" are solid, except for air holes on the two ends. These are held together by clamps "B," shown at larger scale in Fig. 4. The top "C" is held by the hinges "D," shown full-size in Fig. 5. Fig. 2 is a section showing sizes and arrangement of top, bottom and side. Fig. 3 shows at full-size how the clamps are fastened to the glass. The round-headed bolt is passed through a hole in the glass, with leather washers next to the glass on each side, then it passes through the clamp, after which another washer is put on, and a small padlock passed through a small hole in the bolt and locked in place. There are two of is tapped to receive it, so that the head can be removed.
