Abstract
A compound bow includes a pair of improved pivotally mounted cam assemblies having separate, specification profiled string cable segments and power cable segments constructed and arranged to produce a draw force curve representing a greater area of stored energy than that obtained with most existing compound bows. The draw length of the bow, among other parameters, is readily altered without compressing and dismantling the bow cable components by removing and replacing differently configured draw length cam modules associated with the power cable segments. Attachment and subsequent turning of each of the timing, string and power cables is easily accomplished by means of cable adjusters carried by each cam assembly.
Claims22
A compound bow including, a center handle section, first and second resilient limbs extending from opposite ends of said handle section and each having an outermost tip, upper and lower cam assemblies pivotally attached to said bow, each one of said cam assemblies provided with first and second cam segments, a bowstring having opposite ends and substantially spanning the distance between said limb tips, a pair of string cables each having opposite ends respectively joined to each said bowstring end and one of said cam assemblies, one said end of each said string cable having a cam engaging portion sheaved about one said first cam segment, a pair of power cables each having opposite ends respectively joined adjacent one said limb tip and one of said cam assemblies, one said end of each said power cable having a cam engaging portion sheaved about one said second cam segment, and one of a plurality of different sized speed/draw length replaceable cam modules attached to each of said cam assemblies adjacent to and in the same vertical plane as each said second cam segment whereby, as said bowstring is drawn from an at-rest condition said string cables pivotally displace said cam assemblies through said engagement of said string cables with said first cam segments while concurrently said second cam segments initially apply tension to respective ones of said power cables and with further rotation of the cam assembly a full bow draw length is achieved as said power cables are subsequently sheaved about preselected ones of said cam modules.
