Claim:
1. A pulley assembly for a compound archery bow, the pulley assembly comprising a draw cable pulley, a power cable pulley substantially rigidly attached to the draw cable pulley, and an adjustable cable deflector substantially rigidly attached to the draw cable pulley, wherein: (a) the draw cable pulley is structurally arranged so as to (i) define a first pulley assembly transverse rotation axis, (ii) be mounted on a first limb of an archery bow to rotate about the first pulley assembly axis, (iii) let out from a circumferential draw cable journal of the draw cable pulley a draw cable of the archery bow when the bow is drawn and the draw cable pulley rotates about the first pulley assembly axis, and (iv) include a power cable anchor arranged so as to anchor a power cable of the archery bow; (b) the power cable pulley is structurally arranged and positioned on the draw cable pulley so that during drawing of the bow, (i) a segment of the anchored power cable that is displaced from the power cable anchor is taken up by a circumferential power cable journal of the power cable pulley, and (ii) a segment of the anchored power cable that is immediately adjacent the power cable anchor does not make contact with the power cable pulley; (c) one or both of the cable deflector and the draw cable pulley are structurally arranged so as to enable substantially rigid attachment of the cable deflector to the draw cable pulley in any one of a set of multiple deflector arrangements; and (d) for each one of the multiple deflector arrangements, the cable deflector is positioned and arranged (i) so as to deflect laterally the adjacent segment of the anchored power cable by a corresponding amount relative to an undeflected power cable path from the power cable anchor, (ii) so that each corresponding amount of lateral deflection differs from the corresponding amount of lateral deflection for at least one other of the multiple deflector arrangements, and (iii) so that each corresponding amount of lateral deflection remains substantially constant throughout drawing of the bow.
