Illuminated Spiral Wheel First Have A Circular Horizontal Wheel
made two feet diameter, with a hole quite through the nave; then take
three thin pieces of deal, three feet long each, and three-fourths of
an inch broad each: nail one end of each of these pieces to the fell
of the wheel, at an equal distance from one another, and the other end
nail to a block with a hole in its bottom, which must be perpendicular
to that in the block of the wheel, but not so large. The wheel being
thus made, have a loop planed down very thin and flat; then nail one
end of it into the fell of the wheel, and wind it round the three
sticks in a spiral line from the wheel to the block at top; on the top
of this block fix a case of Chinese fire; on the wheel you may place
any number of cases, which must incline downwards, and burn two at a
time. If the wheel should consist of ten cases, you may let the
illuminations and Chinese fire begin with the second cases. The
spindle for this wheel must be a little longer than the cone, and made
very smooth at top, on which the upper block is to turn, and the whole
weight of the wheel to rest.
