  • Hydraulic/pneumatic boost system for archery bow and crossbow
    Patent number: 5445139
    Abstract: Fluid pressure is exerted upon fulcrum or inner end points of the arms of bows (including crossbows, archery bows, and compound bows). The fluid pressure expands fluid cylinders which pull the inner ends of, or push the middle of, the bent arms of the bow. The resulting increase in tension in the arms of the bow produces greater distance traveled, velocity, and therefore accuracy of the missile, when the string is released.
