Patent ID: 7237488

Claim:
A bottle rocket launcher apparatus for use on a ground surface comprising a barrel and a breech valve having a full open position and a full closed position, the launcher having a launcher breech end and a barrel muzzle end; a) the barrel comprising a hollow tube having an inside surface, the barrel having a barrel chamber that compromises all of the inside surface of the barrel, the barrel having a barrel length and the barrel having a barrel axis that extends parallel to the length of the barrel; b) the breech valve being structurally attached to the barrel at the launcher beech end of the barrel wherein the breech valve has a valve body with an exterior surface; c) the breech valve having an internal rotary member, the rotary member having a cylindrical or spherical shape, the rotary member shape having a cylindrical or spherical diameter, and wherein the rotary member is capable of being rotated over an angle that ranges at least between 0 to 90 degrees; d) the rotary member having a through-hole, the through-hole extending through the diameter of the rotary member, the through-hole having a through-hole axis that is located at the center of the through-hole and extends along the length of the through hole; e) the rotary member providing line-of-sight communication from the exterior surface of the breech valve to the barrel chamber such that when the breech valve is in the valve full open position and when the through-hole axis is rotationally aligned parallel with the barrel axis and when at the valve full open position, a continuous passageway opening extending from the external surface of the breech valve through the full length of the barrel chamber is provided; f) the rotary member providing blocked line-of-sight communication from the exterior surface of the breech valve to the barrel chamber when the valve is in the full closed position when the through-hole axis is rotationally aligned perpendicular to the barrel axis; and g) the rotary member having an attached rotary member lever that may be manually rotated to open or close the valve.
