  • Patent number: 6044832
    Abstract: An arrow rest assembly for use with a compound bow. The assembly comprises a bracket subassembly mounted to the frame of the bow or to an overdraw assembly, if the bow is optionally equipped therewith; a cable slide slidably mounted on the cable guide bar of the bow and attached to the tuning cables of the bow; a spring loaded arrow rest subassembly rotatable about an axis synchronously with the movement of the tuning cables as the bow string is drawn and released, the subassembly being pivotally mounted to the bracket assembly and carrying an arrow holder guide; and an actuator cord attached to the arrow rest assembly and downwardly acting tuning cable. When the bow is in the relaxed state, the arrow rest subassembly and the actuator cord are in a relaxed position wherein the actuator cord is slack and the arrow rest subassembly acts to keep the arrow from falling off the bow riser of the bow or the shelf of an overdraw assembly, if optionally present.
