Abstract
Abstract An adjustable arrangement for anchoring the ends of each tension cable in a compound bow includes a displaceable disc cradled in a bridle cable suspended from each bow limb tip. Each disc is provided with a plurality of holes, slots or notches variably spaced from the center of the disc such that the distal portion of a tension cable may be selectively anchored in any one hole, slot or notch thereby allowing tuning of each bow limb by the alternate positioning of the anchored portions of the two tension cables in the respective discs. The slidable, captive engagement between the disc periphery and bridle cable automatically insures maintenance of each tension cable end within a plane passing through the bow centerline.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
163 words
A compound bow including, a center handle section supporting upper and lower limbs having tips, a cam element pivotally attached respective each said limb, a tension cable extending from each said cam element of one said limbs, in a cable end attachment adjacent the opposite one of said limbs, said tension cable terminating in said cable end attachment means adjustably anchoring each said cable end attachment relative its respective said limb, said adjustable anchoring means each including a bridle cable having side portions carried by one said limb and an intermediate portion, a disc engaged and supported by said bridle cable intermediate portion, a plurality of attachment portions formed in said disc disposed varying distances from the center of said disc, and said cable end attachment anchored to said disc by engagement with one of said disc attachment portions whereby, each said cable end attachment is selectively engageable in alternate ones of said disc attachment portions to vary the tuning of said bow.
Claim 2
Dependent Claim
163 words
A compound bow including, a center handle section supporting upper and lower limbs having tips, a cam element pivotally attached respective each said limb, a tension cable extending from each said cam element of one said limbs, in a cable end attachment adjacent the opposite one of said limbs, said tension cable terminating in said cable end attachment means adjustably anchoring each said cable end attachment relative its respective said limb, said adjustable anchoring means each including a bridle cable having side portions carried by one said limb and an intermediate portion, a disc engaged and supported by said bridle cable intermediate portion, a plurality of attachment portions formed in said disc disposed varying distances from the center of said disc, and said cable end attachment anchored to said disc by engagement with one of said disc attachment portions whereby, each said cable end attachment is selectively engageable in alternate ones of said disc attachment portions to vary the tuning of said bow.
