Patent number: 6845794Abstract: Disclosed is a filling system for loading one or more paintball reservoir tubes with paintballs. The system is made of a paintball fill funnel and a support for at least one, and preferably a plurality of reservoir tubes. The fill funnel is dimensioned to fit within the reservoir tube and rest on the rim of the reservoir tube. A support shoulder, rim, or plurality of support shoulders on the outside of the fill funnel form a stable plane atop the tube rim. Each funnel can have more than one spout that communicates with a central funnel chamber for filling a plurality of paintball reservoir tubes simultaneously. The tube support can take a variety of configurations.Type: GrantFiled: November 10, 2003Date of Patent: January 25, 2005Inventor: Lance G. Johnson

Patent number: 6763822Abstract: An electro-pneumatically operated paint ball gun operates without the use of a mechanical sear, and includes a pneumatically operated hammer assembly effective to bump open a discharge valve and fire the gun. A programmable, microprocessor-based controller allows default valves for time intervals of operation of the gun to be programmed, and also allows a user of the gun to access and change default values so that the operation of the gun can be modified to better meet the user's preferences. A rocking trigger assembly allows the user to achieve a faster rate of fire with better accuracy. Accordingly, a cyclic rate of fire of as much as 30 paint ball shots per second or more is possible with a paint ball gun according to this invention. Further, a retrofit kit assembly provides for conversion of a conventional “autococker” type of paint ball gun into a gun embodying the present invention.Type: GrantFiled: October 28, 2003Date of Patent: July 20, 2004Inventor: Leon Styles

Patent number: 6739324Abstract: An automatic functioning device for distributing compressed gas comprises a jack and a distributor. The device successively and automatically carries out the following operations, after the piston has been initially hit on its rear end by a hammer: forward piston displacement, compressed gas intake into the chamber and pressurization of the latter; recoil of the piston to the rear, escape of compressed gas contained in the chamber and depressurization of the latter; return of the piston to the front, closing of the compressed gas intake, escape to the front of the remaining compressed gas contained in the chamber and return of the device to its initial position.Type: GrantFiled: September 13, 2002Date of Patent: May 25, 2004Assignee: RDIHInventors: Leon Hubert, Robert Hubert

Patent number: 6729322Abstract: A compressed gas powered gun provides recoil simulating the recoil of a gun firing gunpowder propelled projectiles. The valve assembly provides both consistent shot to shot pressure, and rearward gas pressure for generating recoil. Preferred embodiments of the compressed gas powered gun may include a system for adjusting the amount of recoil provided. A trigger mechanism permitting semi-automatic operation, or full automatic operation at a user selectable cyclic rate, is provided. The air gun provides consistent gas pressure behind the projectile from shot to shot. A magazine and magazine indexing system for loading projectiles into the firing chamber in a manner contributing to the accuracy of the air gun is also provided.Type: GrantFiled: November 6, 2002Date of Patent: May 4, 2004Inventor: Mark Schavone

Patent number: 6601780Abstract: The present invention relates to a paintgun with pneumatic feeding and discharging process which mainly includes a pneumatic delivery mechanism. The pneumatic delivery mechanism consists of a flow-guiding body, a flow-guiding piston and a delivery tube. The flow-guiding body consists of a major air channel at the front end and a flow-guiding chamber at the rear end thereof. The flow-guiding chamber contains an input port at one side thereof which is in connection with an air pressure source and an output port at the other side thereof which communicates with a minor air channel at the wider part of the flow-guiding body. A stopper is used to control the opening and closing of the air flow channel. The flow-guiding piston is disposed within the flow-guiding chamber. The flow-guiding chamber is divided by the valve body into a front and a rear air pressure chambers with different pressure area.Type: GrantFiled: October 18, 2002Date of Patent: August 5, 2003Inventor: Chih-Sheng Sheng
