Abstract
The present invention is an improved compound bow. In particular, the present invention is directed to an adjustable compound bow for hunting and archery with noise reduction features. The preferred embodiment of the bow comprises a riser having a main riser length with two ends, each end attached to an adjustable hub with a limb base. Each limb base preferably has a pocketless flat surface with vibration dampening material. Each hub is secured to the main riser length by an adjustment worm drive and a hub pivot. A limb is preferably secured to each limb base at two points on the pocketless flat surface. A bowstring is strung under tension between the limbs. The bowstring's tension can be adjusted by adjusting the adjustable hubs with the worm drives. The bow preferably has a storage position and an in-use position caused by rotating the limbs around the adjustable hubs. Adjustment of the bow can be accomplished without use of a bow press.
