A cam assembly for an archery bow is provided. The cam assembly includes a cam body and an anchoring lug. The cam body defines a pivot axis and a groove circumferentially routed at least partially around the pivot axis. The anchoring lug is coupled with the cam body and includes a force sensor. The anchoring lug is offset from the pivot axis and is configured to facilitate attachment of a bow cord thereto. The force sensor is configured to facilitate detection of a tension on the bow cord as a function of a force imparted to the force sensor from the bow cord. An archery bow is also provided.

A cable tensed between a pair of large and small diameter cams of a bow and elastically deformed to generate an elastic force for rotating the pair of large and small diameter cams and a pair of string cams rotated integrally with the pair of large and small diameter cams in a reverse direction when the string is drawn to rotate the pair of large and small diameter cams are rotated. The cable has: a first high-elasticity raw thread wound around one of the pair of large and small diameter cams; a second high-elasticity raw thread wound around the other of the pair of large and small diameter cams; and a low-elasticity raw thread which connects the first high-elasticity raw thread with the second high-elasticity raw thread, the low-elasticity raw thread being elastically deformed more easily than the first high-elasticity raw thread and the second high-elasticity raw thread.

An archery bow with a cam timing belt preferably includes a first cam pulley, a first cam cable, a first timing pulley, a second cam pulley, a second cam cable, a second timing pulley and a timing belt. An archery bow includes a riser, a first limb, a second limb, a first cam and a second cam. The riser preferably includes a first timing projection and a second timing projection. The first cam pulley and the first timing pulley are rotatably retained on the first timing projection. The first cable is preferably secured to a first cam axle and the first cam. The second cam pulley and the second timing pulley are rotatably retained on the second timing projection. The second cable is preferably secured to a second cam axle and the second cam. The timing belt is secured to the first and second timing pulleys.

A line puller attached to the limb adjustment bolts used for adjusting tension on high-performance bows is provided. The line puller may be shaped to facilitate capture of the line around an enlarged projection having a flared flanged that coaxes the line into an overlap configuration to cinch the line on a narrow winding portion.

The split cam for a compound archery bow includes a pair of limbs, each limb having a respective loose end and at least two portions. End members are installed on the loose ends, and each end member has a pulley for a bowstring and two attachments for two cables. In between the loose ends, a first cable and a second cable are located on the same side of the bowstring. For each limb, at least one portion of the limb separates the respective pulley from at least one of the attachments for the first cable and the second cable. The portions may be of different resilience. The cam provides for convenient operation of a compound archery bow, increases initial speed of an arrow when shooting, and increases strength and reliability.

A pulley assembly for a compound bow comprises a draw cable pulley, a power cable pulley attached to the draw cable pulley, and a cable deflector attached to the draw cable pulley and adjustable among multiple deflector arrangements. Deflection of the power cable by the cable deflector remains constant throughout drawing of the bow. Movement of the cable deflector alters deflection of the power cable to alter effective length of the power cable and relative synchronization (with the bow at brace) of the pulley assembly with a second pulley assembly. The adjustment can in some instances be performed without using a bow press and without derigging the bow.

A crossbow includes a frame and a projectile that moves along a projectile axis when the crossbow is fired. The crossbow includes pulleys and cams to improve performance of the crossbow. Some embodiments include multiple-wind cams.

A compound bow includes a first and second pulley, each of which is operative, when the bow is drawn, to unwind a portion of a bow string from a bow string groove and to take up a portion of a bow cable so as to decrease its effective length. At least one of the pulleys includes a cable controller which operates to modify the rate at which the effective length of the bow cable is decreasing so that during an initial portion of the draw of the bow, the rate is greater than it would be in the absence of the controller, and during a second portion of the draw, the rate is less than it would be in the absence of the controller. Use of the controller provides a bow which has an inherently balanced draw.

In some embodiments, an archery bow comprises a frame, a first rotatable member supported by the frame, a second rotatable member supported by the frame and a limb supported by the frame. The first rotatable member comprises a first track, a second track and a cam. The cam comprises a power cable track. A bowstring cable segment extends from the first rotatable member to the second rotatable member. A control cable segment extends from the first rotatable member to the second rotatable member. A power cable extends from the limb to the first rotatable member. When the bowstring is drawn, the first track feeds out the bowstring cable segment, the second track feeds out the control cable segment and the power cable track takes up the power cable. In some embodiments, the frame comprises a riser and a spar. In some embodiments, the first rotatable member is supported by the spar.

In some embodiments, an archery bow comprises a rotatable member configured for rotation about a first rotatable member axis. A cable anchor is attached to the rotatable member and rotatable with respect to the rotatable member about an anchor axis. The anchor axis is offset from the rotatable member axis. The bow can further comprise a power cable anchored to said cable anchor.
