1. In an arrow comprising an arrow shaft and an arrowhead, an improved apparatus for rotatably mounting the arrowhead on the arrow shaft wherein the improvement comprises:
- (a) a support sleeve disposed in a concentric fixed relation at one end of the arrow shaft, said support sleeve having a stop surface and a back end surface;
(b) an arrowhead connector releasably attachable to the arrowhead;
(c) means for axially retaining the arrowhead connector slideably and rotatably within the support sleeve; and
(d) means interposed between the back end surface of the support sleeve and the axial retaining means for resiliently biasing the arrowhead connector against the stop surface of the support sleeve.

Abstract
An apparatus for rotatably mounting an arrowhead on an arrow shaft wherein a biasing force acts to keep the arrowhead in alignment with the arrow shaft. In one embodiment, the apparatus comprises a flanged support sleeve in the end of a hollow arrow shaft and an arrowhead connector, wherein the shank of the connector is retained in the support sleeve with a biasing force acting to pull the connector and attached arrowhead back against the flange of the support sleeve. The biasing force is of adjustable magnitude for use with arrowheads of differing weights.

3. An apparatus for mounting an arrowhead on a front hollow end of a arrow shaft, the apparatus comprising:
-
(a) a support sleeve sized to be concentrically secured in the front hollow end of the arrow shaft, said support sleeve having a front end surface, a back end surface and a flange shaped to bear against the front hollow end of the arrow shaft; (b) an arrowhead connector, said connector having shoulder and a shank portion, said shank being longer than and rotatably and slideably extending through said support sleeve; (c) securing means attached to the connector shank at a position behind the back end surface of the support sleeve; and (d) resilient biasing means interposed between the securing means and the back end surface of the support sleeve for resiliently biasing the shoulder of the connector against the front end surface of the support sleeve. - View Dependent Claims (4, 5, 6, 7, 8)

9. An arrow shaft insert for use with an arrow of the type which comprises an arrowhead comprising an externally threaded shank portion for mounting the arrowhead and an arrow shaft comprising a shaft with a hollow end, said insert comprising:
-
(a) a support sleeve comprising an internal bore, a flanged front end configured to bear against the hollow end surface of the arrow shaft, a back end surface, and a scored outside surface sized to fit tightly within the hollow end of the arrow shaft; (b) an arrowhead connector comprising a head, shoulder, body and extension such that the body slideably fits within the support sleeve, the extension extends beyond the back end surface of the support sleeve and the shoulder fits over the flanged front end of the support sleeve with the head in front of the flanged front end; (c) the arrowhead connector also comprising an internally threaded portion sized for receiving the arrowhead shank portion; (d) means for retaining the arrowhead connector within the support sleeve; and (e) means interposed between the back end surface of the support sleeve and the retaining means for resiliently biasing the shoulder of the arrowhead connector against the support sleeve flanged front end. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
