  • Patent number: 6807959
    Abstract: A pneumatic device for firing projectiles with a charge of compressed air that accelerates a projectile carrier and the projectile through a barrel. The charge of compressed air is released into the barrel behind the projectile carrier and acts on the projectile carrier to initially accelerate it and a ball or other projectile down the barrel. The diameter of the projectile carrier is slightly less than that of the barrel and it includes a concave recess that receives balls of differing diameters, centering as they are accelerated through the barrel. The barrel is sufficiently long so that the projectile carrier comes to a halt before being ejected from the barrel. An intake for a compressor that develops the charge of compressed air is coupled in fluid communication with the barrel, behind the projectile carrier. Operation of the compressor produces a partial vacuum so that ambient air pressure forces the projectile carrier back to its firing position.

  • Patent number: 6776121
    Abstract: The freezeless method for watering livestock, in one embodiment, is a method and means to provide water to livestock using a well, trough and a piston pump that is activated and powered by the animal. The animal uses its nose to push a plate on a lever apparatus that is attached to the pump. The pushing motion causes a rod to move the piston pump, which in turn raises water to the surface via piping into the trough where the animal drinks the water. The animal continues to pump the lever apparatus until the desired amount of water is consumed. By using a drain means and insulation means, the apparatus operates in freezing temperatures without the use of a power or heat source.

  • Patent number: 6772548
    Abstract: An adjustable trigger assembly adapted for installation into the carrier of an AK-47 and similar rifles. The assembly features a plurality of adjusting screws to adjust the force required for trigger pull, the over travel of the trigger after firing, and the forward rotational force and angle of a disconnector rotationally engaged in a slot in the trigger to thereby allow for adjustment of the force required during both stages of pull of a two stage trigger to fire the weapon. The device is adapted for engagement with the receiver of a conventional AK-47 in replacement of the original trigger mechanism and may be used with the original hammer or optionally may employ a replacement hammer which features limited contact with the trigger assembly to lessen the trigger pull required for firing.

  • Patent number: 6766795
    Abstract: The invention provides an improved gun for firing a projectile comprising a grip, a receiver, a projection on either the grip or receiver and a retainer fixedly attached to the other, so that the projection and retainer selectively engage each other, retaining the grip and receiver in a fixed relationship. The apparatus provides a safety retainer and a safety projection, whereby the safety retainer and safety projection engage one another when the hammer is in the ready position, maintaining the grip and receiver in the fixed relationship. A safety member is provided preventing the retainer from disengaging the projection when the hammer is in the ready position, and blocking the hammer from moving into the ready position when the retainer is not in the first position and the hammer is not in the ready position. The invention provides a process for making a receiver for firing a projectile.

  • Patent number: 6763822
    Abstract: 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.

  • Patent number: 6761102
    Abstract: A recoil control mechanism for a weapon which fires a projectile which is characterized by the generation of a forward counterforce to the rearward recoil simultaneously with absorption of rearward recoil force upon initiation of propoulsion of the projectile. The forward counterforce is generated by propelling a first mass forwardly upon firing the projectile and substantially simultaneously propelling a second mass rewardly for absorbing some of the recoil force. In one mechanism (10), the first mass may be the weapon's barrel (12) and the second mass its breach block (14). Expaning gases (36) from detonation of propellant in cartridge (24) enter a reaction volume (28) between the barrel (12) and breech block (14). These gases drive barrel (12) forwardly against force transmission spring (16) to impose a forward counterforce on the weapon's frame (18).

  • Patent number: 6752063
    Abstract: A multiple cell ammunition cradle system for a weapon wherein the rate of ammunition transfer and the consequent rate of fire of the weapon is independent of the azimuth angle of the weapon. The system generally includes a cradle having a rotor with a plurality of cells formed therein. The cradle may be disposed in a charging position and a loading position. When in the charging position, each of the cells is controllably, selectively alignable with an ammunition hoist to receive an ammunition component in each cell. When the cradle is pivoted into the loading position, the rotor may be positioned so that each of the cells is alignable with the barrel of the weapon so that the ammunition component may be loaded into the weapon and fired.

  • Patent number: 6752137
    Abstract: The present invention is a projectile launching system having an independently operable gas powered less-lethal launcher, which is capable of firing projectiles containing either incapacitating, debilitating, or marking agents for use during those situations when lethal force would be an inappropriate response. The gas powered launcher is ergonomically designed and comprises a receiver housing and receiver that are detachable from a stand-alone stock so that it can be attached to a mounting bracket located underneath the barrel of a rifle and, therefore, integrated with such rifle in order to provide both a lethal and a less-lethal capability for the user. One of the ergonomic features of the receiver is that it is designed to releasably carry a compressed gas container in a way that presents a favorable profile and a convenient and efficient trigger location, even after attachment of the receiver to the barrel of a rifle.

  • Patent number: 6742475
    Abstract: A variable shut off teat cup liner has a mouthpiece, a barrel and a short milk tube adapted for mounting onto milking claw. The short milk tube includes a segment for engagement with an edge of a claw nipple defining an opening, the segment being intended for bending over the opening to substantially close it to passage of vacuum-drawn air therethrough when the teat cup liner is in a non-milking generally downwardly bending position. The segment has circumferentially extending grooves and longitudinally extending grooves which form lugs which provide improved cut resistance. The circumferentially extending grooves have different axial spacing whereby the amount of overlap of the short milk tube over the nipple may be varied to provide the proper amount of bending.
