ABSTRACT:
A multiple draw archery bow having a single draw string that is drawn to a full drawn position a plurality of times providing energy of deformation to flexible bow limbs, storing the energy from each full draw using a mechanical mechanism such as a block and tackle mechanism, and providing the stored deformation energy back to the same draw string for launching the arrow with a force and a velocity that is greater than can be derived from a single full draw of a draw string from a standard compound bow that allows only one full draw of the draw string. The mechanical mechanism allows the archer to draw the draw string of the multiple draw bow to a plurality of full drawn positions with a lower average draw force than a standard compound bow that launches an arrow at the same launch velocity as the present multiple draw bow.
