Definitions

  • ABSTRACT [52] U.S. Cl 42/55, 46/199, 89/7,
  • I employ an elongated hollow tube or cylinder with one open end and a disc with a small central hole sealing the other end and disposed at right angles to the axis of the cylinder.
  • a second parallel disc with a like central hole is disposed in the cylinder adjacent the end disc and remotely spaced from the open end.
  • the portion of the cylinder subtended between the discs constitutes a combustion chamber.
  • Lighter fluid is squirted into the chamber via the opening in the end disc and the cylinder is shaken a few times to distribute the fluid and allow at least some of it to vaporize.
  • the cylinder is then inclined upward, open end at top and the fluid is ignited by holding a lighted match or lighter adjacent the opening in the end disc. A loud noise is produced in a harmless manner.
  • the top portion of the cylinder (that portion which is not the combustion chamber) can be charged with small plastic balls which will be ejected from the cylinder when the fluid is ignited.
  • FIG. 1 is a perspective of my invention in use
  • FIG. 2 is a longitudinal cross section of my invention per se
  • FIG. 3 is a cross section taken along line 33 in FIG.
  • FIG. 4 is a cross section taken along line 4I in FIG. 2;
  • FIG. 5 is an elevation of a can of lighter fluid used in my invention.
  • I provide an elongated rigid hollow cylinder or tube llil which can be about 3 feet long and about 8 inches in inner diameter, or a ratio of 36 to 8.
  • One end 12 is open; the opposite end is sealed by a first rigid disc I4 disposed at right angles to the axis of the tube and having asmall central opening 16 which can be one half inch in diameter or a ratio to the inner diameter of one-half to 8.
  • a second disc It with like opening 16' and parallel to the first disc is disposed in the tube, for example, being separated from the first disc by a space of about 6 inches in a ratio to the overall length of 6 to 36.
  • lFluid from lighter fluid can lb is squirted into the space between the discs via the opening in the end disc.
  • the tube is then shaken several times to distribute the fluid and to allow at least part to vaporize.
  • the tube is then upwardly inclined at an angle of 45 or larger with respect to the horizontal, open and upward.
  • a lighted match or lighter 26]! is held adjacent the hole in the end disc to produce ignition and the desired noise.
  • a harmless firework comprising:
  • an elongated hollow cylinder open at one' end; a first disc near the other end and disposed at right angles to the axis of the cylinder and having a small central opening;
  • a second disc of like diameter disposed in the cylinder and parallel to the first disc, the second disc having a small central hole, the second disc being spaced both from the open end and the first disc but being much closer to the first disc than to said open end;
  • the ratio of the inner diameter to overall length of the cylinder being about 2 to 9;
  • the ratio of the separation between the discs to the overall length of the cylinder being about I to 6;
  • the ratio of the diameter of said central hole to the inner diameter of the cylinder being about I to 16.
