** Magic-Box Escape [7]

The things required to make this trick are a heavy packing box
with cover, one pair of special hinges, one or two hasps for as
many padlocks and a small buttonhook, says the Sphinx.

The hinges must be the kind for attaching inside of the box. If
ordinary butts are used, the cover of the box

must be cut as much short as the thickness of the end board. The
hinges should have pins that will slip easily through the parts.

Before entering the box the performer conceals the buttonhook on
his person, and as soon as the cover is closed and locked, and the
box placed in a cabinet or behind a screen, he pushes the pin or
bolt of the hinge out far enough to engage the knob end with the
buttonhook which is used to pull the pin from the hinge. Both
hinges are treated in this manner and the cover pushed up,
allowing the performer to get out and unlock the padlocks with a
duplicate key. The bolts are replaced in the hinges, the box
locked and the performer steps out in view.
