  • Patent number: 5896849
    Abstract: An improved arrow rest for use in combination with an archery bow is disclosed. The present arrow rest provides complete radial support to an arrow disposed in a ready-to-draw position even if the bow is tilted or rotated radially relative to an axis of the arrow. Such radial support is provided by an inverted coil brush comprising a disc-shaped structure having a plurality of radially disposed, inwardly projecting bristles of a predetermined length attached therein forming a central opening in the arrow rest wherein the arrow shaft is radially supported. The bristles are arranged within the coil brush so as to impart no significant hindrance to the passage of an arrow therethrough. Thus, no angular orientation of the arrow vanes to the arrow nock is required which permits the use of the arrow rest with any configuration of arrow fletching or number of vanes.
