Abstract

Abstract An archery bow and drawstring pulley assembly which is mounted at each end of an archery bow limb for receiving a drawstring. Each pulley assembly includes a first U-shaped housing which is connected to a bow limb, a second housing which is U-shaped and receivable between the U-shaped first housing walls. A pulley wheel is mounted on a pin disposed within the second housing. The first and second housings are hinged together, which allows the second pulley housing to be pivoted relative to the first housing. A rigid shaft is connected to the first and second housings which allows for threadably adjusting the position of the second housing with respect to the first housing. The pulley assembly allows for precise tensioning adjustment of the bow drawstring by movement of the positioning shaft to the exact desired position without experiencing any loss of bow string force.
