Abstract

An arrow with a reduced diameter nock comprising a cylindrical arrow shaft in a tubular configuration having a pointed end and a fetching end and an exterior diameter and an interior diameter. Fetching extends outwardly from the arrow shaft adjacent to the fetching end. A cylindrical bore extends into the arrow shaft at the fetching end, the bore having an internal diameter. A nock has a cylindrical forward end with an exterior diameter to frictionally fit into the bore of the arrow shaft, and has a rearward end of a diameter essentially equal to that of the exterior diameter of the arrow shaft, the inboard end being formed with a deep hole for an acute angle bowstring.

Claims

1. A new and improved arrow with a reduced diameter nock comprising, in combination:

a cylindrical arrow shaft (12) in a tubular configuration having a pointed end and a fletching end and an exterior diameter and an interior diameter;

fletching extending outwardly from the arrow shaft from the fetching end;

a cylindrical bore (28) extending into the arrow shaft at the fletching end, the bore having an internal diameter;

a nock having a forward end and a rearward end, the rearward end having a diameter essentially equal to the exterior diameter of the arrow shaft, the forward end having a first cylindrical portion (30) abutting the rearward end and extending forwardly therefrom, the first cylindrical portion having an exterior diameter to frictionally fit into the bore (28) of the arrow shaft, the forward end having a second slender cylindrical portion (38) extending forwardly from the first cylindrical portion, the second cylindrical portion having an external diameter less than that of the bore (28) and the first cylindrical portion, thereby forming a bearing shoulder at the junction of the first and second portions; and

a cylindrical supplemental shaft (42) positioned in the arrow shaft at the fletching end ahead of the nock, the supplemental shaft having a second cylindrical bore (40), the external diameter of the second cylindrical portion of the forward end of the nock being such that the second cylindrical portion has a frictional fit in the bore of the supplemental shaft thereby to insure proper bonding and rotational adjustability of the nock.

2. The arrow as set forth in claim 1 and further including:

indented rings formed in the supplemental shaft at measure intervals whereby the supplemental shaft can be cut to a desired length or weight.
