Abstract
A compound bow with a pair of limbs having a pair of improved eccentric pulleys rotatably affixed adjacent free ends thereof and adapted to receive a bowstring and a tension cable on center line of said bow, said compound bow optionally having roller cable adjustment deflectors for use with said improved eccentric pulleys to deflect the tension cables away from a sight window in the compound bow.
Claims7
In a compound bow including a frame, a pair of limbs carried by said frame, a pair of eccentric pulleys carried by said limbs and positioned adjacent the free ends thereof, a first tension cable mounted to a first one of said eccentric pulleys, a second tension cable mounted to a second one of said eccentric pulleys, and a bowstring mounted at opposite ends thereof to said eccentric pulleys, the improvement wherein said eccentric pulleys mount the bowstring and the first and second tension cables, wherein said eccentric pulleys are substantially circular in cross-section and have circumferentially disposed substantially circular symmetrically spaced grooves for receipt of mounting means whereby said bowstring and said tension cables are mounted thereto, each of said pulleys having three grooves which are substantially uniform in diameter and having four holes substantially symmetrically spaced about the margin thereof, one of which serves as a pivot to said limbs, and wherein a first passageway interconnects a first outer one of said grooves to an inner one of said grooves and wherein a second passageway interconnects a second one of said grooves to one of said holes, said passageways converging by passing substantially along the diameter of said eccentric pulleys whereby torque in said improved compound bow is reduced.
In a compound bow including a frame, a pair of limbs carried by said frame, a pair of eccentric pulleys carried by said limbs and positioned adjacent the free ends thereof, a first tension cable mounted to a first one of said eccentric pulleys, a second tension cable mounted to a second one of said eccentric pulleys, and a bowstring mounted at opposite ends thereof to said eccentric pulleys, the improvement wherein a pair of removable cable adjustment deflectors are carried by said frame and wherein said cable adjustment deflectors are rollers located between and offset from said eccentric pulleys and positioned to deflect said tension cables away from a sight window in said frame.
