Patent number: 5174268Abstract: Eccentric wheels of a compound archery bow are mounted in respective bow limb receiving slots for pivotal movement between a rest draw angular position and a full draw angular position. Each wheel pivot axis extends transversely across the respective wheel receiving slot and is spaced an effective preset slot depth distance A from the respective slot root. Each wheel has a bowstring portion with a peripheral bowstring track formed therein for receiving a section of a bowstring. The peripheral bowstring track has a progressively increasing moment arm radius relative to the respective pivot axis from a rest draw segment to a full draw segment. The moment arm radius from the pivot axis to the full draw segment of the bowstring portion is greater than the effective slot depth distance A to extend the effective length of the respective flexible power limb at the full draw angular position by a distance greater than the slot depth.Type: GrantFiled: June 20, 1991Date of Patent: December 29, 1992Assignee: Martin Archery, Inc.Inventors: Terry G. Martin, George T. Newbold

Patent number: 5103797Abstract: An adjustable arrow rest apparatus comprises a base which is mountable to an archery bow handle and an elongated support bar extending therefrom. An arrow launcher assembly is movably mounted to the support bar for lateral movement. The support bar has an elongated slot formed longitudinally therein at a selected position between its outer and inner ends. The longitudinal slot has opposed relative outer and inner terminuses. A longitudinal opening is formed through the outer terminus and communicates with the slot. A threaded rod is slidably received through the outer terminus opening and passes longitudinally within and along the slot. The threaded rod is secured in a manner which precludes sliding of the threaded rod through the outer terminus opening and along the slot, yet enables rotation of the threaded rod within the outer terminus opening and slot. An adjustment block is received within the slot, and has a threaded bore through which the threaded rod is threadedly received.Type: GrantFiled: March 6, 1991Date of Patent: April 14, 1992Assignee: Martin Archery, Inc.Inventor: George T.

Patent number: 5081980Abstract: An arrow rest apparatus for attachment to an archery bow handle comprises a cushion plunger assembly and an arrow support. The cushion plunger assembly has an elongated inner plunger and an elongated outer sleeve, the inner plunger being received within the outer sleeve and projecting therefrom. The inner plunger is outwardly biased to an extended position relative to the outer sleeve and is depressible to a depressed position against the bias to absorb side pressure exerted by an arrow in the direction of the bow upon shooting. The cushion plunger assembly is laterally mountable through an archery bow handle to engage a side of an arrow with the inner plunger. Upper and lower mounting holes extend through the outer sleeve and are generally vertically opposed and aligned. A slot is formed longitudinally through the elongated inner plunger.Type: GrantFiled: October 10, 1990Date of Patent: January 21, 1992Assignee: Martin Archery, Inc.Inventor: George T. Newbold

Patent number: 5062407Abstract: An arrow launcher apparatus for adjusting an arrow launcher laterally along an elongated lateral support bar of an arrow rest apparatus, wherein the support bar has a male dovetail-shaped cross-section. The arrow launcher apparatus has an arrow launcher support block which supports an arrow launcher. A threaded bore extends generally laterally through the support block. A dovetail slot in the support block is slidaly received by the arrow rest lateral support bar and allows the support block to slide laterally relative to the support bar. A set screw is threadably received in the support block and is positioned to engage the arrow rest lateral support bar. The set screw can be tightened to lock the support block at a selected lateral position along the arrow rest lateral support bar. End blocks, each with dovetail slots, are received by the lateral support bar and are clamped to the support bar by set screws. Each end block has a lateral barrel at its fore end.Type: GrantFiled: June 21, 1990Date of Patent: November 5, 1991Assignee: Martin Archery, Inc.Inventor: George T. Newbold

Patent number: 5052364Abstract: An adjustable arrow rest apparatus for mounting to a handle of an archery bow comprises, a) a base which is mountable to an archery bow handle; b) a support bar extending from the base; c) a first arrow launcher movably mounted to the support bar for lateral movement therealong; and d) a second arrow launcher movably mounted to the support bar for lateral movement therealong independent of the first arrow launcher. The second arrow launcher comprises: a) a substantially upright support so movably mounted to the support bar; b) a side pressure absorbing unit to absorb side pressure exerted by an arrow in the direction of the bow handle, the side pressure absorbing unit being movably mounted to the upright support for selective elevational movement relative thereto; and c) a set screw or other components for releasably setting the side pressure absorbing unit at a selected elevational position relative to the upright support.Type: GrantFiled: August 15, 1990Date of Patent: October 1, 1991Assignee: Martin Archery, Inc.Inventors: Terry G. Martin, George T. Newbold

Patent number: 5022378Abstract: An overdraw apparatus supports an arrow for shooting at a support location between the drawstring full-draw rearward position and the drawstring full-forward travel position upon its release. A construction is provided whereby the drawstring can pass through and beyond the support location, and thereby enable much shorter arrows to be shot from a conventional bow than would otherwise be possible. In one embodiment, the actual arrow support includes two members which are separated by a space which allows the drawstring to pass therebetween. In another embodiment, the arrow support includes a pivotally mounted arm which gets struck by the bowstring and pivots forwardly to accommodate the movement of the drawstring forwardly beyond the support location.Type: GrantFiled: January 2, 1990Date of Patent: June 11, 1991Assignee: Martin Archery, Inc.Inventors: Nolin C. Rhodehouse, Terry G. Martin, George T. Newbold

Patent number: 4899716Abstract: An arrow rest apparatus for an archery bow includes a base, a support bar extending from the base, and a support block slidably mounted to the support bar. The support block and the support bar have a dovetail sliding interconnection to enable sliding movement of the support block along the support bar, but to preclude any rotation of the support block about the support bar. The support block is selectively lockable relative to the support bar to set the support block at the desired position. An arrow launcher is pivotally mounted by the support block and includes a fore end adapted for receiving an arrow. The fore end is upwardly biased by a tapered spring. A first set screw engages the tapered spring enabling its compression to be adjusted and correspondingly the force required to pivot the arrow launcher about its pivot axis. A second set screw engages the aft end of the arrow launcher enabling the resting elevation of the arrow receiving portion to be selectively varied.Type: GrantFiled: December 28, 1988Date of Patent: February 13, 1990Assignee: Martin Archery, Inc.Inventors: Terry G. Martin, George T. Newbold, Theodore M. Davenport
