Preparation

The Table:

Fig. 51 gives an illustration of the table. The sides are cut out with a scroll saw. The top sets on loose so it can be easily lifted off. The table base is 29 inches high, 28 inches long and 18 inches wide.

Figs. 52 and 53 give cross section views of table. Fig. 54 shows how sides are held together

with corner blocks and reinforcing strips. The table base packs in one piece. The table should be decorated.

The Box:

From the standpoint of the audience the box looks just like a nicely decorated box with a lid and a door in front which can be opened so that they can look into the box, Figs. 55-56.

However, it is magically arranged in a very clever way.

The sides, top and bottom are arranged so they can be easily dissected. The various sides are held together with hinge joints. Fig. 57 shows this arrangement. The pin is soldered in one part of the hinge and attached to one side of box while the other part of hinge is attached to adjoining side. When both parts of hinge are fitted together the sides are held together but they can be easily separated by moving one side to the side and pulling pin out of other part of hinge. Fig. 57 shows hinge separated while Fig. 58 shows how the sides of box are held together. It requires two hinges on each edge of side to be attached to another.

Fig. 59 shows a cross section of box and arrangement of hinges.

Fig. 60, next page, shows another cross section of the box, looking from top down. On one side you will note a special metal and wooden container that revolves on a pivot and arranged so it can be swung to the inside or the outside.

Fig. 61 gives another cross section of the box showing container with its raised wooden lid and door on its front. The container is concealed from audience because it is into this that the doves are placed to be vanished.

Fig. 62 gives another cross section of the container. Also Figs. 63, 64 and 65. The latter figures show how container is pivoted to swing in the side of box.

The front part of the container is fitted with special bars - Figs. 66 and 67 on next page show this.

The bar arrangement is for the special purpose of causing the birds to "vanish" suddenly from the eyes of audience and are similarly constructed as the visible "vanish" screen in Lesson 52.

There are really two sets of bars one behind the other. The rear set is covered with black cloth and slides in a groove. When rear bars are parallel with front ones audience can see into box. When rear bars are moved to cover openings in front set, the vision is cut off. Box is dark inside with lid closed and it is difficult to tell whether the openings between bars are closed or open. A piece of glass is behind the rear bars far enough back so as not to interfere with bars sliding.

Fig 68 is a cross section working view of how front of dove container is built. Note the metal door, the permanent front bars, the sliding rear bars and the glass at back. Note also the catch in metal door, the pivot and the small slots cut in sides of box proper to receive Stop K so it can only go so far and hold swinging container in proper position.

Fig. 69, next page, gives another cross section working view showing position of pivots, etc.

The rear bars are pulled back and forth by means of a string attached to ends of rear bar set. The string runs through ends of front side of container and then out into box proper and through side of box where it can be easily controlled from outside. This is the one that closes the bars and shuts off inside of box view from audience. The other cord to open bars again is merely a short one running out opposite end of front side of container. The container is painted black inside. The front bars are painted the same color as the bars in barred compartment.

Barred Compartment for Doves or Ducks:

This is a special section that is shown to audience and placed into the box for the purpose of holding the animals placed therein. Fig. 70-71, next page, shows the container which is 22 x 12 x 6 inches. It is made of wood. The bars are same size and same distance apart as those in the special container. It is painted black inside. The outside color may vary.

Fig. 72, next page, shows how compartment fits into box behind the dove container.

When compartment is put into box audience thinks you slide it up to front of box next to door. When you open front door audience sees the bars of the real container and thinks it is looking at the bars of the compartment you just placed into the box. The audience never knows of the revolving container into which the doves or ducks really go. They are led astray by the other barred compartment.

To the audience this is just a nicely decorated cage with a hinged top and front door, Fig. 73, for the purpose of holding the live stock to be used in the illusion. The cage, however, has a DOUBLE purpose in that it not only holds the doves or ducks, but has a specially prepared top for the purpose of eventually concealing the live stock to be "vanished".

Fig. 74 shows the under side of top which merely appears to be reinforced by two-by-fours.

The cage is 20 inches wide, 30 inches long and 24 inches high.

Figs. 75, 76, 77 and 78 will give you a good idea of the construction of the top of cage with its movable panel which can be depressed at will. This is accomplished by curtains on spring rollers. The spring rollers have enough tension to keep panel in normal position until undue pressure is brought to bear on panel when panel sinks down supported on each end by a curtain.

Fig. 78 shows cross section of panel depressed when the side of box with container full of doves or ducks is placed on top of cage.

Fig. 78 shows cross section of panel depressed when the side of box with container full of doves or ducks is placed on top of cage.

This gives appearance to audience of side of box being flat. They cannot see one side of the side but when it is laid down flat on top of cage they naturally take it for granted that there is nothing on other side, never figuring that there is a load which pushed down the top panel of cage to make room for it.
