Arrow nock and shaft insert
First Claim
1. A nock for attachment to the nock end of a hollow arrow shaft via an insert, the insert having an introduction end, a receiving end located opposite the introduction end, a substantially cylindrical body extending from the receiving end to the introduction end, and a receiving chamber having an opening at the receiving end and extending a distance into the cylindrical body, the receiving chamber being axially aligned and communicating with a threaded duct which extends farther through the cylindrical body toward the introduction end, the nock comprising:
- a) a string receiving end for receiving a bow string;
b) an engaging shank located opposite the string receiving end, the engaging shank having a size and shape to permit threaded engaging between the engaging shank and the threaded duct; and
c) a compression shank extending between the string receiving end and the engaging shank, the compression shank having a size and shape for insertion into the receiving chamber to produce a friction fit therewith, the compression shank further having an exterior surface with compression knobs formed thereon.

Abstract
A nock system including an insert and a nock. The insert having an introduction end, a receiving end located opposite the introduction end, a substantially cylindrical body extending from the receiving end to the introduction end, and a receiving chamber having an opening at the receiving end and extending a distance into the cylindrical body. The receiving chamber is axially aligned and communicates with a threaded duct which extends farther through the cylindrical body toward the introduction end. The nock comprises a string receiving end for receiving a bow string and an engaging shank located opposite the string receiving end. The engagement shank has a shape and size permitting self-tapping, threaded engagement between the engaging shank and the threaded duct. A compression shank extends between the furrowed end and the engaging shank. The compression shank has a shape and size to produce a friction fit within the receiving chamber as the engaging shank is positioned within the threaded duct.
