Patent number: 5660160Abstract: This invention, the Pneumatic Launcher, is an improved, compressed inert gas powered, launching system for the airborne delivery of soft promotional items to persons in an arena or stadium environment. It is manually operable by one person. Receiving its power from a tank of compressed inert gas (usually nitrogen) fitted with a regulator and a three way manifold with two air lines and a relief valve, the unit has two hoses attached to its rear housing plate. One line fills the accumulator tank while the auxiliary line insures the pneumatic trigger always has gas pressure to complete the firing cycle. A ball valve of 11/2 or larger releases the volume of gas from the accumulator tank quickly and completely, much more so than solenoid operated valves by virtue of the pneumatic air ram mechanism attached to the valve stem by a balanced cam type "T" shaped handle assembly. The released gas is channeled through a 180.degree.Type: GrantFiled: June 7, 1995Date of Patent: August 26, 1997Assignee: Melvin Eulan PrescottInventor: Melvin Eulan Prescott, Jr.

Patent number: 5613483Abstract: A piston and cylinder assembly for a gas powered gun, has a cylinder containing a piston rod slidably movable between a loading position in which the leading end of the piston rod is in a withdrawn position, and a firing position in which the piston rod has moved forwardly. The cylinder has first and second chambers through which the piston rod extends, the cylinder being connectable to a pressurized gas supply supplying pressurized gas to the first chamber when the piston rod is in the loading position. The piston rod permits communication between the pressurized gas supply and the first chamber and prevents communication between the first and second chambers when in the loading position, and when in the firing position prevents communication between the pressurized gas supply and the first chamber and permits communication between the first chamber and the second chamber to cause pressurized gas in the first chamber to pass into the second chamber.Type: GrantFiled: November 9, 1995Date of Patent: March 25, 1997Inventors: Michael A. Lukas, Roger L. Hurst, Lee D. Kirwan

Patent number: 5586545Abstract: Two embodiments of a compressed gas gun are disclosed. In the first embodiment, a slidable barrel supported by two barrel guides is employed. A thermoplastic compression sleeve provides a bearing for the slidable barrel, which impacts a valve assembly upon actuation of a trigger mechanism. The impact momentarily opens the valve thereby releasing compressed gas and expelling a projectile. An anti-rebound lock prevents rebound of the barrel and subsequent discharge of gas. In the second embodiment, a slidable bolt assembly serve the function of impacting the valve. The barrel is rigidly attached to the frame of the gun and a spring forces the slidable bolt assembly against the valve. A seal is provided between the slidable bolt assembly and the barrel for allowing slidable movement and preventing the loss of compressed gas.Type: GrantFiled: October 2, 1995Date of Patent: December 24, 1996Inventor: John A. McCaslin

Patent number: 5450839Abstract: There is disclosed a pneumatic launcher comprising a cylindrical storage member and a cylindrical barrel which are coaxial, and a cylindrical body therebetween. Pressurized gas is coupled into the chamber of the body. A valve member has a sleeve portion which telescopingly receives the cylindrical body. The gas entering the chamber leaks through the space between the sleeve portion and the body to fill the reservoir. The valve member has a second valve portion which is conical and movable against a valve seat. When it is desired to launch a projectile in the barrel, gas is exhausted from the chamber causing the valve member to snap back to its opened condition almost instantaneously to deliver gas from the reservoir to the barrel, thereby to launch the projectile therein.Type: GrantFiled: September 21, 1993Date of Patent: September 19, 1995Inventors: Isakov S. Nicolaevich, Isakov I. Nicolaevich, Yurkin S. Vasilievich

Patent number: 5348059Abstract: The invention is an attachment for airguns and/or similar devices powered by compressed gas. The unit is multi functional in that it facilitates rapid refilling of a connected gas supply vessel from a bulk supply source, without the necessity of removing the supply vessel from the airgun. The adaptor also provides the basic benefits of a simple expansion chamber, effectively providing compensation for periodic introduction of any liquid gas propellant from the gas supply vessel caused by handling or orientation of the airgun and/or aerosol supercharging.Type: GrantFiled: September 7, 1993Date of Patent: September 20, 1994Assignee: Air AmericaInventor: Kent L.

Patent number: 4601278Abstract: A bullet is fired from an ammunition cartridge upon piercing a breakaway section in the rear wall of the cartridge to form a gas escape port. The cartridge has one open end in which is seated the bullet and the breakaway section of the rear wall is directly opposite the bullet. A moveable sealing element is adapted to move between two positions. One position seals off the opening in the one end, and the other position is displaced from the opening to allow gas to escape under pressure from the opening. Piston-type element, in response to the housing wall being pierced, stops the flow of gas from this escape port and moves the sealing element from the first to the second position.Type: GrantFiled: June 24, 1983Date of Patent: July 22, 1986Inventor: Hyung S.
