Abstract
An arrow includes a first shaft member, and a second shaft member. The second shaft member has an exterior surface and an interior surface defining a reservoir portion capable of containing a fluid. The arrow also includes a coupling member for coupling together the first and second shaft member. The coupling member includes a first and second cap member. The first cap member has an outer surface attachable to the first shaft member, and a threaded inner surface. The second cap member has an outer surface attachable to the interior surface of a second shaft member, a threaded inner surface, and an aperture in fluid communication with the reservoir portion. A stud member is provided which has a first threaded end portion for threadedly engaging the first cap member, a second threaded end portion for threadedly engaging a second cap member, a middle portion extending between the first and second end portions, a first fluid conduit extending in at least a portion of each of the second portion a middle portion, and sealing means for selectively sealingly engaging the first and second shaft members to controllably regulate the flow of fluid therebetween.
