Adjustable weight arrow point
First Claim
1. An adjustable-weight arrow point comprising an arrow point assembly including a point element,an arrow shaft coupling section defining a hollow core having an inner wall, and weighting means for securement within said arrow point assembly for incorporating selectable additional weight into said assembly,said weighting means comprising an elongate bar, said bar being formed with a plurality of lineally-spaced, radial grooves demarking a lineal, coaxial array of incremental weight segments,said weighting means projecting interiorly of said coupling means coaxially therewith, and extending rearwardly of said coupling section,said point element being formed at a rearward end thereof with thread means for threaded engagement with said elongate bar, coaxially therewith,said bar being formed at its forward end with thread means for coupling engagement with said thread means of said point element,said coupling section being formed with radially inwardly directed collar means for abutting said bar sleevedly projecting therewithin,interengaging threads of said point element and said elongated bar comprising means for lockingly securing said coupling section fixed with said point element and for establishing said rod, said coupling section, and said point element as a stable composite assembly, andsaid elongate bar being severable at any of selectable said grooves to leave a selectable number of said incremental weight segments within said arrow point assembly to establish said bar as an arrow-point-housed weight controlling component thereof.

Abstract
An arrow point with a selectably-adjustable, incrementally-stepped array of weight-regulating elements. The weighting elements are demarked lineal component segments of an elongate rod or bar which is deeply grooved radially at incremental, lineally-spaced positions along its length. The rod is threaded at its forward end for coupling engagement with a threaded neck portion of the arrow point. Prior to sleevedly assembling the arrow point with the shaft of the arrow, the segmental rod is severed at a particular pre-set groove to leave a selectable number of weight segments attached. The latter remain as a secured, weight-adjusting core component of the arrow point assembly. An O-ring seated in a diminutive, outwardly-opening annular groove formed in a sector of the rod forwardly of the segmental array bears upon an enveloping inner wall of the body of the point assembly to stabilize and to lock the rod frictionally within the core of the arrow point.

1. An adjustable-weight arrow point comprising an arrow point assembly including a point element,
an arrow shaft coupling section defining a hollow core having an inner wall, and weighting means for securement within said arrow point assembly for incorporating selectable additional weight into said assembly, said weighting means comprising an elongate bar, said bar being formed with a plurality of lineally-spaced, radial grooves demarking a lineal, coaxial array of incremental weight segments, said weighting means projecting interiorly of said coupling means coaxially therewith, and extending rearwardly of said coupling section, said point element being formed at a rearward end thereof with thread means for threaded engagement with said elongate bar, coaxially therewith, said bar being formed at its forward end with thread means for coupling engagement with said thread means of said point element, said coupling section being formed with radially inwardly directed collar means for abutting said bar sleevedly projecting therewithin, interengaging threads of said point element and said elongated bar comprising means for lockingly securing said coupling section fixed with said point element and for establishing said rod, said coupling section, and said point element as a stable composite assembly, and said elongate bar being severable at any of selectable said grooves to leave a selectable number of said incremental weight segments within said arrow point assembly to establish said bar as an arrow-point-housed weight controlling component thereof.

2. The arrow point assembly as set forth in claim 11 and further comprising O-ring seated in an annular groove formed in and encircling said elongate bar forwardly of said segments thereof for stressingly bearing upon said coupling section of said arrow point assembly against an enveloping said inner wall thereof to stabilize and to lock said bar frictionally within said arrow point assembly.
-
10. The structure as set forth in claim 11, wherein said coupling section of said arrow point assembly is formed interiorly thereof at a forward zone thereof with a rearwardly presented annular shoulder for abutment of a forward end face of said bar thereagainst, and wherein said coupling section includes a bushing-like collar for receiving a forwardly directed annular neck-like projection of said rod therewithin in contiguous nesting relation therewith.
