US Patent 11709031 Compound projectile launcher

A projectile launcher including a frame having a grip and defining a projectile axis, a drawstring hub rotatable mounted to the frame and defining a central axis perpendicular to the projectile axis and positioned a fixed distance from the projectile axis, a drawstring being attached to the drawstring hub so that movement of the drawstring results in the rotation of the drawstring hub about the central axis, a limb coupled to the frame and extending along a vertical limb plane, and a power cable coupled to the limb and the drawstring hub so that rotation of the drawstring hub about the central axis draws the limb closer to the central axis.
