ABSTRACT:
The compound archery bow includes a central riser section with handle and bow window on one side and first and second limbs connected to opposite ends of the riser. The limbs bear eccentric levers, such as wheels eccentrically mounted on transverse axles. A telescoping arm is secured to the riser and extends rearwardly thereof, bearing a rotatable wheel on the outside thereof and adjacent its rear end. A bowstring is disposed longitudinally between the limbs behind the riser. A first cable is connected at one end to the bowstring and at the other end to the first limb axle. It is locked intermediate its ends to a first circular groove in the arm wheel and is secured to the lever in the first limb. A second cable is similarly connected at one end thereof to the opposite end of the bowstring and at the other end thereof to the second limb axle. It is locked intermediate its ends to a second circular groove in the arm wheel and is secured to the lever in the second limb. Only one of the two cables crosses itself intermediate its ends. The telescoping arm permits easy adjustment of draw length and draw weight and the arm wheel prevents damage to the limbs of the bowstring breaks. The arm also provides necessary arrow clearance of the cables without distorting the limbs.
