Patent number: 8347869Abstract: Quiet, lightweight, well-balanced, forgiving, and accurate compound archery bows which have significantly reduced vibration and bow jump. The limbs and cams of these bows can be removed and replaced without a bow press, and the limbs of the bows are functional (active) over essentially their entire length and allow one to obtain equivalent performance from a more compact and lighter bow. The bow limbs may be leverage locked in articulated limb pockets. The limb butts extend forward well beyond the front of the riser. This eliminates limb length and limb angle as major factors in determining brace height, allowing one to choose a riser style and limb length which optimize arrow speed and bow stabilization. Novel adjustment mechanisms allow one to easily adjust the poundage or poundage and brace height of the bow. Vibration isolation systems may be employed to isolate the bow riser from the limb pockets.Type: GrantFiled: October 9, 2008Date of Patent: January 8, 2013Assignee: Sims Vibration Laboratory, Inc.Inventors: Steven C.

Patent number: 8205607Abstract: A compound archery bow includes a handle having projecting limbs, and first and second pulleys mounted on the limbs for rotation around respective axes. First and second cable anchors are disposed on the base adjacent to respective ends of a cable groove. A bow cable arrangement includes a bowstring cable extending from a bowstring anchor on the first pulley around a bowstring let-out groove and then toward the second pulley. A first cable extends from the first anchor on the first pulley through a portion of the cable groove on the first pulley and then toward the second pulley. A second cable extends from the second anchor toward the second pulley.Type: GrantFiled: June 30, 2009Date of Patent: June 26, 2012Assignee: Darton, Inc.Inventor: Rex F. Darlington

Patent number: 8196570Abstract: According to one embodiment, a bow includes a handle portion and a bowstring. Compression members including primary compression elements and secondary compression elements are positioned on the ends of the handle portion. The compression elements are arcuate in shape and joined at the ends. As the bowstring is drawn, the compression members are compressed and energy is stored therein. The bow can include limbs that do not significantly deform or store energy as the bow is drawn. Upon release of the bowstring, the stored energy is rapidly returned to the bowstring.Type: GrantFiled: March 9, 2010Date of Patent: June 12, 2012Assignee: TDJ IncorporatedInventors: Ronald J. Christensen, Jason Christensen

Patent number: 8136514Abstract: An archery or similar projectile launching device having a spring assembly to energize the device and a release mechanism to transmit energy stored within a torsion or alternative spring to the bowstring, so as to accelerate an arrow nocked to the bowstring once the trigger is released. In one embodiment, conjoined cranks wind a torsion spring within a spring motor affixed along the riser of the bow while the bowstring and arrow are concurrently brought into the discharge position. A mechanical advantage may be achieved with the cranking mechanism to reduce the effort exerted by the archer and thereby increase accuracy, velocity and ease of use.Type: GrantFiled: July 30, 2008Date of Patent: March 20, 2012Assignee: JRH Industries, LLCInventors: Jack Ryan Howard, Patrick L. Muscarella

Patent number: 8082910Abstract: A pulley assembly for a compound archery bow comprises a set of multiple power cable pulleys and a draw cable pulley. The draw cable pulley is arranged to be rotatably mounted on a bow limb, to let out the draw cable when the bow is drawn, and so as to have interchangeably mounted thereon any one of the multiple power cable pulleys. Each power cable pulley is arranged to take up the power cable when the bow is drawn. At least one of the power cable pulleys is arranged so as to result in substantially negligible let-off of draw force of the bow. At least one other of the power cable pulleys is arranged so as to result in substantial let-off of the draw force of the bow at a corresponding draw length.Type: GrantFiled: February 29, 2008Date of Patent: December 27, 2011Assignee: Extreme Technologies, Inc.Inventor: Craig T. Yehle
