A centering device maintains center alignment of the tubes when the tubes are locked in a telescopic position. Threaded bores are provided at the outer ends of the tubes for attachment of the improved telescopic stabilizer to an archery bow and for the attachment of weights, additional stabilizer, or for use as a bow prop device. Plugs with threaded bores are typically used on inner ends for attachment of a locking member. The locking member is eccentrically and rotably attached to the plug. A bolt extends through the off center bore through the locking member. The bolt is screwed and tightened into an eccentrically located threaded bore on the plug. The locking member in the preferred embodiment has an internal interlock that locks the locking member to the bolt. This helps prevent the tubes from loosening during repeated shooting of the bow.Type: GrantFiled: February 23, 1996Date of Patent: September 23, 1997Inventor: Charles E. Breedlove

Patent number: 5657741Abstract: A quick-release coupling for connecting a stabilizer to an archery bow. The coupling has a sleeve that is moveable linearly away from the bow in order to separate the two halves of the coupling, one of which is connected to the bow and the other connected to the stabilizer.Type: GrantFiled: October 19, 1995Date of Patent: August 19, 1997Inventor: Gary J. Todd

Patent number: 5649527Abstract: A combination archery bow stabilizer and string tracker mounting adaptor having a telescopic capability to raise or lower the string tracker. Used in conjunction with a 360 degree rotatable arm to which the string tracker is mounted, minimization of the noise created by slack string tightening upon launching an arrow is possible. The adaptor and rotable arm are capable of adjustment for the needs of the individual archer or archery bow to which it is mounted.Type: GrantFiled: June 5, 1995Date of Patent: July 22, 1997Assignee: Jon P. DohertyInventors: Arthur V. Olsen, Dennis James Heath

Patent number: 5630407Abstract: A T-shaped connecting piece is provided to enable a front stabiliser and two counter-stabilisers to be fastened on the central bow part of a sports bow. The connecting piece may be screwed in the threaded hole provided in the central bow part for this purpose and may be clamped on the central bow part in the correct rotational position by means of a threaded tube. The counter-stabilisers are shifted further forward owing to the T-shape of the connecting piece, so they do not impair the archer. Owing to the clamped connection between the connecting piece and the central bow part, the transmission of the strong vibrations produced during the firing of an arrow from the sports bow to the stabilisers is optimally guaranteed so excellent shots may be fired.Type: GrantFiled: April 20, 1994Date of Patent: May 20, 1997Assignee: AGF Gasser AGInventor: Max Gasser

Patent number: 5630568Abstract: An archery bow holder for holding an archery bow in a desired position and orientation by supporting an archery bow counterweight from a surface. The archery bow holder comprises a bow counterweight support and a threaded shaft extending therefrom. The threaded shaft is twisted into the surface; and the bow counterweight is inserted into the bow counterweight support, thereby supporting the archery bow from the surface.Type: GrantFiled: February 24, 1995Date of Patent: May 20, 1997Assignee: Advanced Hunting Equipment, L.L.C.Inventor: Edward Lubrecht

Patent number: 5619981Abstract: An archery bow stabilizer and prop generally having a locking adaptor that attaches to the bow. A transition elbow attaches to the locking adaptor. A stabilizer-prop extends downward from the transition elbow. The stabilizer-prop in the preferred embodiment is telescoping to provide height adjustment. The lower end of the stabilizer-prop is inserted into a reciever attached to a hunting surface. The transition elbow also allows a conventional stabilizer to be used in conjunction with the stabilizer-prop. The stabilizer screws into another threaded bore at the end of the transition elbow. There is fixed and a stationary type transition elbow. Both allow attachment of the stabilizer-prop in a downward vertical position to hold the bow in an upright position. Both allow a conventional stabilizer to be screwed into the end, holding the stabilizer in an extended position, which is conventional in nature.Type: GrantFiled: February 5, 1996Date of Patent: April 15, 1997Inventor: Charles E. Breedlove

Patent number: 5617664Abstract: The improved stabilizer has a hollow elongated preferably cylindrical housing with a central space extending the length thereof to open opposite ends. An end cap closes one end of the housing and bears a connector for attachment of the housing to a weapon. The opposite end of the housing has an end cap rotatably secured thereto to close the housing. The housing is filled with oil or grease. First and second springs, preferably coiled springs, are connected to the interior of the two end caps and to opposite ends of a weight suspended in the space of the housing. An indexer is provided on the rotatable end cap to indicate its rotated position and to releasably hold it in that position. As the end cap is rotated it increases or decreases, depending on its direction of rotation and the extent of its rotation, the tension on the springs, thus controlling their degree of resistance to displacement of the weight during shock absorption.Type: GrantFiled: August 21, 1995Date of Patent: April 8, 1997Inventor: Vincent F. Troncoso

Patent number: 5615664Abstract: A weight collar for use with a stabilizer adapted to be connected to a bow. The weight collar is removably connected to a stabilizer outer peripheral surface of the stabilizer. The weight collar includes a pad constructed of a compressible material whereby the weight collar is movable in upwardly and downwardly directions perpendicular to an axial center line of the weight collar and movable in angular directions relative to the axial center line of the weight collar while remaining attached to the weight collar. A stabilizer for use with a bow having a stabilizer tube with an opening extending therethrough forming a stabilizer chamber, the stabilizer chamber defining a stabilizer in a peripheral surface. A resonator suppressor ring is disposed in the stabilizer chamber between the first and the second ends of the stabilizer tube.Type: GrantFiled: November 29, 1995Date of Patent: April 1, 1997Inventor: Norman J. McDonald, Jr.
