  • Patent number: 9719752
    Abstract: A spear for use with a spear gun includes a hollow shaft having a leading end and a trailing end opposite the leading end, a piston retained in the hollow shaft and configured to slide within the hollow shaft, and a check valve. The piston forms a seal with an inner surface of the hollow shaft and divides the hollow shaft into a pre-charge chamber toward the leading end and a firing charge chamber toward the trailing end. The check valve is in fluid communication with the pre-charge chamber and is configured to permit a pressurized gas pre-charge to enter the pre-charge chamber and restrict the gas pre-charge in the pre-charge chamber from exiting the pre-charge chamber.

  • Patent number: 9526234
    Abstract: A bowfishing arrow and method of bowfishing. The bowfishing arrow includes a shaft having a main stem. A locking pin is slidably movable within a bore of the main stem. A fish point with a pair of pivoting barbs is secured to the distal end of the main stem. An outer sleeve is longitudinally movable with respect to the main stem and the locking pin is engaged with the outer sleeve to move with the outer sleeve. The barbs pivot between a shooting position, a locked position, and an unlocked position. When in the locked position, an end of the locking pin is clamped between cams preventing the barbs from pivoting to toward the unlocked position and the shooting position until the fish is landed. A one-handed maneuver is all that is required to release the arrow from the fish after it is landed.

  • Patent number: 9297624
    Abstract: A device and method introduces the use of conventional ammunitions to the archery/bow hunting industry. The device achieves stealthy delivery of firearm munitions and increases the firepower of standard arrows resulting in deeper penetration into a target. The device consists generally of a cylindrical housing threaded internally on one end for attachment to a firing pin assembly. A firing pin is slideably attached to the firing pin assembly. A cartridge is loaded into the housing until the flange on the cartridge casing abuts an interior shoulder. In an alternate embodiment, the interior of the housing further includes an annular retaining tab. The retaining tab separates the cartridge from the firing pin to prevent inadvertent discharge. A cap or nosepiece may be included to further protect the device from accidental discharge of the cartridge and to provide aerodynamic advantages. The housing further includes a set of stabilizing vanes.

  • Patent number: 8960094
    Abstract: A bullet defines a chamber and mechanism for extending an explosive body from the chamber. The chamber has a broader top portion than a lower portion. The bullet further defines a channel passage leading out of the top end of the bullet. The bullet contains the explosive body slidably engaged within the channel passage. A shaft is connected to the body and passes down from the body into the lower portion of the chamber. A thrust plate is connected to the shaft end in the chamber. The thrust plate is spring metal and when the cartridge is fired, the thrust plate rises pushing the body so that it extends from the leading end of the bullet. When the thrust plate rises to the second portion of the chamber, it springs open to prevent subsequent downward motion of the thrust plate and consequently prevents subsequent retraction of the body during flight.

  • Patent number: 6311623
    Abstract: An arrow is provided with a head that will take game in a more humane way and without long suffering. This new arrowhead is a dual powder-charged multiple-strength powered projectile that is activated after a delayed interval. As a result of the unleashed power caused by this activation, the arrowhead's bullet housing point will just flare out and the cases will induce powerful venting to rupture the vital organs nearby, or it will flare out and separate itself from the rest of the housing, the tissue anchored arrowhead causing damage by its path forward. Because all this action occurs inside the game's body, it is silent but gravely stunning to all organs. The result is on the spot drop and expiration, with minimal suffering and positive retrieval.

  • Patent number: 5343809
    Abstract: The invention relates to a weapon whose main object is to attack targets, such as armoured tanks, from above unexpectedly. The weapon includes an active part (1), a propulsion unit, such as a launching device (2), an anchorage attachment (4) which is intended to be firmly anchored in relation to the terrain, and a line (3) whose first end (5) is attached to the active part (1) and whose second end (6) is pivotally attached to the anchorage attachment (4). When used, the active part (1) is launched vertically upwards, with the line (3) held taut, whereafter the active part is guided by the line through the air in a circular arcuate path or trajectory (8) to a target (7), with the centre of the arcuate trajectory in the anchorage attachment (4).

  • Patent number: 5202533
    Abstract: A remote injection device for animals comprises a barrel with a piston slideable within the barrel from an initial retracted position at one end of the barrel forwardly toward the opposed end of the barrel to discharge liquid in an injection action through a needle at the forward end of the barrel. The piston is held in a retracted position by an O-ring on a release member which projects through an O-ring carried on the inside surface of the barrel. The inner diameter of the O-ring on the barrel can be adjusted by axial movement of the pair collars on the inside of the barrel. This adjusts the amount of force necessary to push the release member O-ring through the outer O-ring to release the piston to be moved by spring to the discharge position. The barrel can be mounted either upon an arrow type projectile so the impact forces are sufficient to release the piston upon engaging the animal.

    Abstract: A projectile having a tubular projectile body and provided with pointed fins pivotally mounted at the front end of the projectile body. The head fins expand when the projectile strikes a target shark to prevent the projectile from passing clear through the shark and to present a wound which is covered by a searing agent which is released from the interior of the body when the projectile strikes the target. The searing agent sears the wound, eliminating bleeding which attracts predators. Several embodiments of the projectile are disclosed.

  • Patent number: 3978790
    Abstract: A sonobuoy for launching at high altitudes from present sonobuoy launching tubes. A plurality of spring loaded stabilizing fins are held in place adjacent the body of the sonobuoy by rotovanes in their stored position. Upon launching the sonobuoy from an aircraft, the stabilizing fins assume their stabilizing position substantially perpendicular to the body of the sonobuoy due to the spring action but are held in place by the stored rotovanes. Upon reaching a lower altitude, the rotovanes are released to allow rotochute action to slow the descent of the sonobuoy. Upon deployment of the rotovanes to their operating position, the stabilizing fins previously held in place by the stored rotovanes separate to allow proper rotochute action.
