Abstract

An arrow shaft socket is disclosed which solves the problem of inserting a hollow threaded socket into a cavity in an arrow shaft without forcing adhesive within the cavity to flow onto the threaded portion. This problem is solved by forming a substantially hemispherical radius on the front of the insert end and providing a small air hole in the insert end. An alternate embodiment can include the provision of one or more axial grooves along the outside of the insert to permit excess adhesive to flow out of the cavity.

Claims

1. An improved arrow shaft socket for mounting an end portion of the arrow thereto, comprising:

a substantially cylindrical, hollow tube with an open end and a substantially closed end, having an inner, cylindrical, threaded surface of an inner radius and an outer, cylindrical surface of an outer radius;

said closed end of said tube having a small, substantially circular hole therethrough, substantially coaxial with said inner cylindrical surface, having a radius substantially smaller than said inner radius;

said closed end of said tube having an external surface substantially hemispherical in shape, with a radius substantially the same as said external radius;

whereby said tube may be more easily inserted into an adhesive coated, axial hole in one end of an arrow shaft, allowing entrapped air to pass through said small hole without the adhesive flowing onto said threaded surface.

2. The apparatus of claim 1, wherein said open end of said tube has an external flange thereon, for seating said tube in said hole in the end of the arrow shaft.

3. The apparatus of claim 1, wherein said outer, cylindrical surface of said tube has a plurality of circumferential grooves therein for anchoring said tube in said hole in the end of the arrow shaft.

4. The apparatus of claim 3, wherein said outer, cylindrical surface of said tube has an axial groove therein to permit excess adhesive to flow from said hole in the end of the arrow shaft when said tube is inserted therein.

5. The apparatus of claim 4, wherein there are a plurality of said axial grooves in said outer, cylindrical surface.

6. The apparatus of claim 1, wherein said outer, cylindrical surface of said tube has an axial groove therein to permit excess adhesive to flow from said hole in the end of the arrow shaft when said tube is inserted therein.

7. The apparatus of claim 6, wherein there are a plurality of said axial grooves in said outer, cylindrical surface.

8. In combination, an improved arrow shaft socket for mounting an end portion of the arrow to an arrow shaft, comprising:

a substantially cylindrical, hollow tube with an open end and a substantially closed end, having an inner, cylindrical, threaded surface of an inner radius and an outer, cylindrical surface of an outer radius;

an end portion which threadably engages said inner surface of said tube;

said closed end of said tube having a small, substantially circular hole therethrough, substantially coaxial with said inner cylindrical surface, having a radius substantially smaller than said inner radius;

said closed end of said tube having an external surface substantially hemispherical in shape, with a radius substantially the same as said external radius;

whereby said tube may be more readily inserted into an adhesive coated, axial hole in one end of an arrow shaft, allowing entrapped air to pass through said small hole without the adhesive flowing onto said threaded surface.

9. The combination of claim 8, wherein said end portion is an arrow tip.

10. The combination of claim 8, wherein said end portion is a stabilizing feather assembly.

11. The combination of claim 8, wherein said end portion is an arrow shaft extension.

12. In combination, an improved arrow shaft socket for mounting an end portion of the arrow to an arrow shaft, comprising:

a substantially cylindrical, hollow tube with an open end and a substantially closed end, having an inner, cylindrical, threaded surface of an inner radius and an outer, cylindrical surface of an outer radius;

an end portion which threadably engages said inner surface of said tube;

said closed end of said tube having a small, substantially circular hole therethrough, substantially coaxial with said inner cylindrical surface, having a radius substantially smaller than said inner radius;

said closed end of said tube having an external surface substantially hemispherical in shape, with a radius substantially the same as said external radius;

an arrow shaft having an adhesive coated axial hole in one end thereof into which said outer surface of said tube is mounted;

whereby said tube may be more easily inserted into said adhesive coated, axial hole in one end of said arrow shaft, allowing entrapped air to pass through said small hole without the adhesive flowing onto said threaded surface.

13. The combination of claim 12, wherein said end portion is an arrow tip.

14. The combination of claim 12, wherein said end portion is a stabilizing feather assembly.

15. The combination of claim 12, wherein said end portion is an arrow shaft extension.
