Method of micro adjusting cam timing and cam orientation on an archery bow

Abstract

A method of micro adjusting cam timing on an archery bow includes separating filaments of a cable or bow string to form a split area and inserting an adjustment spacer into the split area. The adjustment spacer causes a length of a bow string or cable to be shortened. The split in the cable or bowstring requires moving the limbs toward each other to allow the filaments of a cable or bowstring to be separated for insertion of the adjustment spacer. However, the cable or bow string may be sold with a pre-inserted split holder to allow the adjustment spacer to be inserted into the bow string without the need for a bow press. The adjustment spacer includes a middle perimeter, which tapers outward in opposing directions to a larger retention perimeter. The split holder is preferably a thin disc with a plurality of notches formed around a perimeter thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) With reference now to the drawings, and particularly to FIGS. 1-2, there is shown an adjustment spacer 10 or a split holder 12. With reference to FIG. 3, a micro adjusting method preferably includes separating filaments 103 of a cable 102 or bowstring 104 to form a split area 106 and inserting the adjustment spacer 10 into the split area 106. The adjustment spacer 10 causes a length of a bowstring 104 or a cable 102 to be shortened. When the adjustment spacer 10 is retained in the cable 102 it enables the bowstring 104 to have an increased draw length. The split area 106 in the cable 102 or bowstring 104 requires compressing limbs 108 of an archery bow 100 with any suitable method, such as a bow press to release tension of the filaments 103 of the cable 102 or bowstring 104 to be separated to allow insertion of the adjustment spacer 10 or split holder 12.

(7) The cable 102 or bowstring 104 may be sold with a split holder 12 to allow the adjustment spacer 10 to be inserted into the split area 106 of the cable 102 or bowstring 104 without the need for compressing the limbs 108. However, the split holder 12 could be inserted between filaments of the cable 102 or bowstring 104 while the cable 102 or bowstring 104 is being constructed. The split holder 12 is moved up or down the cable 102 or bowstring 104 to create the split area 106 in any part of a length of the cable 102 or bowstring 104. The adjustment spacer 10 and the split holder 12 preferably include a middle perimeter 14, which tapers outward in opposing directions to a larger retention perimeter 16. A shortened length of the cable 102 or bowstring 104 is proportional to a length of the middle perimeter 14. However, other designs of the adjustment spacer 10 and split holder 12 may also be used. Alternatively, the adjustment spacer 10 and the split holder 12 could be the shape of a rod fabricated from material, which is soft enough to compress when pressure is applied by the plurality of filaments of the cable 102 or bowstring 104, such as rubber or wood.

(8) The following dimensions are given by way of example and not by way of limitation. It is preferable that dimension A have a range of between 0.005-0.5 inches. It is preferable that dimension B have a range of between 0.25-1.0 inches. However, other dimensions may also be used. The adjustable spacer 10 and the split holder 12 may be fabricated from any suitable material, such as a plastic, a metal, a rope, wood or any combination of materials. The adjustable spacer 10 and the split holder 12 are retained in the cable 102 or bowstring 104 by axial tension of the cable 102 or bowstring 104.

(9) With reference to FIGS. 3-4, an adjustment spacer 18 or split holder 20 includes a base plate 22 and a plurality of separation projections 24 extending from one side of the base plate 22. The adjustment spacer 18 or the split holder 20 is being used to create multiple split areas 106 in a cable 102 or a bowstring 104. A shortened length of the cable 102 or bowstring 104 is proportional to a perimeter length of each separation projection 24.

(10) While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects, and therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
