Abstract: A compound type archer's bow is provided with a concentric sheave at each of the bow limb tips, and a pivotable lever with a pulley is mounted at each end of the bow handle. The levers are connected via a continuous stretch reeved over each lever and extending to the most remote sheaves on the bow limbs and then to the ends of the bowstring. A tensioning cable of fixed length is connected between each lever and its respective nearby or adjacent sheave. As the bowstring is drawn the draw force will vary due to the pivoting of the levers. When the levers pass over dead center the tension cable will engage a member on each lever and limit the maximum draw of the bowstring.
