Table Rockets.
6. TABLE ROCKETS.
This is a simple application of Rockets to the spokes of a wheel; to which when fixed they form the felloe. Their effect (when fired) in the ordinary manner is merely that of revolving round on a fixed centre, till their composition is consumed; and by their revolutions representing a vertical or an horizontal circle of fire.
The spokes must be firmly fixed into a block of wood, of lengths and at a distance from each other suitable to the lengths of the cases employed. The cases should be those of twelve or sixteen ounces; and filled with the composition given at No. 8 or 9: they must be carefully rammed.
When the ends of the Rockets are fixed to the spokes, which should be notched out proper to receive them and for the purpose of making them more secure, then in the side of each case, (outward from the wheel) bore a hole of common dimensions near the clay; these holes should be made in an oblique direction towards the charge, and in and from each must be carried a piece of quick-match to the centre of the wheel, where they must be tied together and lighted. At the centre of the wheel may be fixed a similar or larger case; which, being lighted at the same time, will add much to the exhibition.
The centre of the wheel is frequently fitted to a block of wood, and fired upon a table, when it forms an horizontal wheel; otherwise it revolves on an axis fixed to a post, and in this case a vertical wheel is represented; the centre case may be applied to either.
