  • Patent number: 5107819
    Abstract: An arrow holding and loading device for an archery bow has a frame to be bolted to the bow so that it can support a carriage that moves horizontally from left to right at the arrow plate side of the riser, through a window in the arrow plate side of the riser, or to the rear of the riser to automatically shift a follow-up arrow into shooting position upon release by the archer of an initial arrow.

  • Patent number: 4986251
    Abstract: A magazine for an air gun comprises an outer case, a circular pellet carrier rotatably mounted in the outer case, and a cover that is pivotally mounted on the outer case. A coil spring resiliently biases the pellet carrier towards an end position. To load the magazine, the cover is pivoted to cause the pellet carrier to rotate to another end position, and a soft lead airgun pellet is then dropped in through a hole in the outer cover into a pellet chamber in the pellet carrier. The outer cover is then rotated, allowing successive pellets to be dropped into successive pellet chambers within the pellet carrier. In use, a probe pushes the first pellet out of the magazine into the breech of an airgun, and following this, the magazine automatically indexes under spring pressure to present the next pellet ready for loading. The pellets themselves serve as part of the indexing mechanism. The transfer probe places the pellets accurately in position within the breech of the airgun.

  • Patent number: 4850328
    Abstract: An air gun, especially an air pistol, with a piston (2) movable in a weapon housing in a pressure chamber and adapted to be brought to a cocking position against a spring pressure by a cocking arrangement (7, 8, 9) that engages said piston (2). The barrel (6) has a rear barrel opening (5) in which is insertable an elongated profiled bullet (4). In the weapon housing is situated a bullet magazine (16) for several consecutively arranged bullets (4), the inner space (17) of the bullet magazine is at least approximately adapted to the profile of the bullets and the bullets are prestressed in the direction toward the barrel opening (5) via a feed device (19, 20).

  • Patent number: 4823762
    Abstract: An arrow holding and loading device for an archery bow has a frame to be bolted to the bow so that it can support a carriage that moves horizontally from left to right at the front of the bow to automatically shift a follow-up arrow into shooting position upon release by the archer of an initial arrow. A novel arrow nock having one side longer than the other is disclosed and it enables the bow string to be engaged from the side to facilitate rapid shooting.

  • Patent number: 4662345
    Abstract: Apparatus and method of providing for a semi-automatic crossbow embodying a new cocking device and a new magazine. The cocking device consists of a pulley system mounted to the frame of the crossbow and operated by a filament. The crossbow is cocked by holding the grip of the device in one hand, and pulling the cocking handle with the other hand. Each time the crossbow is cocked, a pulley carriage is automatically returned to its original position by use of springs or elastic bands. The device may be fired as quickly as the device may be cocked and trigger pulled. A clip device is utilized to hold bolts to be fired. The bolts are stacked vertically and spring fed upwardly to the chamber each time the crossbow is cocked. The bolts are held in place by constant spring pressure against the bolt track along which the bolt are driven. The clip utilizes two arms that scissor upward and raise the bolts substantially levelly.
