Abstract: Systems, devices, and methods for a one-time disposable device arrangement for dispersing liquids of varying viscosities, or their constituents, in a metered manner over a definable period of time. The invention employs a flexible reservoir, of varying size, shape, and configuration, along with a calculated, finite length of looped flexible tubing, one of varying size, shape and configuration. The device arrangement can be hung over an area where it is desired to attract animals such as deer by dispensing liquids, such as but not limited to animal attractants, such as deer urine and buck jam, and the like.

Abstract: Arrow vanes, devices and methods for improving arrow vane airfoils for compound arrows, crossbow arrows and traditional arrows, which improves flight characteristics over traditionally manufactured, configured and/or applied vanes. Compound bends in the base of the vanes can be done by clamping the vanes in a channel having a generally straight portion and a generally bent portion. The bent portion can have a helical right bend or a helical left bend. A fletching jig can be used to glue the compound bent bases of the vanes to sides of an arrow shaft.

Abstract: Disclosed is a broadhead arrowhead. The broadhead arrowhead includes a ferrule, one end portion of which is tapered to a substantial point. One or more blade assemblies extend outwardly from the ferrule. Each blade assembly has a first substantially planar main surface portion disposed in a plane at least substantially parallel to a longitudinal axis of the ferrule and a second surface portion having a planar region offset at an angle to the plane of the main surface portion. A generally continuously curved region is disposed between and connecting the first and second substantially planar portions, such that the blade assembly has an airfoil-type shape.

Abstract: The present invention is a spirally grooved arrow shaft that imparts axial rotation to an arrow assembly. The shaft has a plurality of substantially identical, helical, longitudinal channels along its outer surface extending down a substantial portion of the arrow shaft along its primary axis. The channels may consist of a plurality of grooves cut into the outer surface of the arrow shaft. Alternatively, the channels may be formed from a plurality of raised-fins or raised members that extend radially outward from the surface of the shaft. The invention is compatible with all contemporary arrowheads and vanes provided that all aerodynamic surfaces present on these devices urge rotation of the arrow assembly in the same direction as the spiral channels.

Only the first planar portion of the blade assembly is coupled to the ferrule thereby allowing the second portion to flex during penetration of a target and achieve greater penetration depth.

Abstract: The invention is a mechanical broadhead arrowhead. The broadhead arrowhead includes a ferrule. A fixed main blade assembly extend outwardly from the ferrule. This main blade assembly has a first substantially planar portion disposed in a plane at least substantially parallel to a longitudinal axis of the ferrule and a two continuously curved second portions offset at angle to the plane of the first planar portion such that the blade assembly has an airfoil-type shape. A number of deployable blades attached to the ferrule also have substantially planar portions and continuously curved portions. The main blade and deployable blades act together as an axial flow turbine during flight. The ferrule further comprises an inertial trigger mechanism that both inhibits premature deployment of the deployable blades during release and flight, yet also promotes deployment of deployable blades during impact with a target.

Abstract: The invention is a system of arrow vanes of novel geometry. The leading edge of each vane is parallel to the long axis of the arrow shaft, and the trailing edge of each vane is deflected out of the plane of the vane like an airfoil causing rotation during flight. All vanes of the invention are identical with all deflected portions facing the same direction when the arrow is viewed down its long axis. The invention also includes one or more vents in the vane surface. Careful placement of these vents decreases aerodynamic drag upon initial release from a bow and also once rotational speed is achieved.

Abstract: The present invention is a system of locking arrow blades that provide excellent main shaft rotation without producing a large amount of aerodynamic drag. This system, including a plurality of v-shaped blades, is attached to the forward end of any conventional arrow shaft or integral to the forward end of any conventional arrow shaft.

Abstract: The invention is a cylindrical arrow ferrule device that is inserted between the arrowhead and the main shaft of an arrow or as an integral part of a hollow arrow shaft. A key feature of the invention is an internal actuator that slides down an inner chamber of the device. Prior to impact, this actuator is magnetically coupled to the aft wall of the chamber; but, upon impact, the resulting force releases the actuator that then slides forward to impact the forward wall of the chamber. This actuation provides the same inelastic collision associated with a dead-blow hammer, thereby driving the arrow into the target.
