Publication number: 20060016080Abstract: A long blade of a knife has first and second working end portions disposed at opposite sides of the blade central portion. The central portion of the blade is pivotally attached to a handle such that, in a first position, the first working end portion is exposed for use and the second working end portion extends along the handle, and in a second position, the second end portion of the blade is exposed for use and the first end portion of the blade extends along the handle. A spring biased locking mechanism is provided to retain the blade in either of the first or second positions.Type: ApplicationFiled: January 31, 2005Publication date: January 26, 2006Inventor: Spencer Frazer

Patent number: 6941661Abstract: A biasing system for the blade of a folding knife includes one component or assembly applying a force tending to move the knife blade from a closed position, nested in the handle, to an open position, extending from the handle. A second component or assembly resists opening of the blade, particularly when the blade is in or near the closed position. The resisting force is overcome by the opening force after the blade has been moved through a predetermined angle relative to the handle, so that the blade then opens automatically. A safety can be actuated to block opening and/or closing of the blade. The blade can have a blunt projection upon which a user may press to move the blade through the predetermined opening angle. A clip can be provided for convenient attachment of the folding knife to an object such as a garment.Type: GrantFiled: August 8, 2002Date of Patent: September 13, 2005Inventor: Spencer Frazer

Patent number: 6282997Abstract: A multipurpose tool having pivoted jaws is provided. Elongated handles are attached to the butt end of each jaw. The handles are channel shaped and define recesses into which the interconnected jaw members can be swung or retracted so as to be nested in the handles. Handle covers are pivoted to each handle and include an opening through which the jaw members pass when moved between the open and closed positions.Type: GrantFiled: June 18, 1999Date of Patent: September 4, 2001Assignee: SOG Specialty Knives, Inc.Inventor: Spencer Frazer

Patent number: 6070504Abstract: Cooperating jaws are pivoted together such that working end portions of the jaw members are movable toward and away from each other. The jaws have butt portions extending opposite the jaw pivot from the working end portions. Such butt portions are, in turn, pivoted to elongated handles for swinging about axes parallel to the axis of the jaw pivot. The handles are channel shaped and define recesses into which the interconnected jaw members can be swung so as to be nested in the handles or, alternatively, into which the interconnected jaw members can be retracted so as to be partially contained within the handles. The handles have forward portions interconnected by a tension spring, and cooperating cam surfaces to bias the handles to predetermined angular positions.Type: GrantFiled: April 22, 1998Date of Patent: June 6, 2000Assignee: SOG Specialty Knives, Inc.Inventor: Spencer Frazer

The handles are channel shaped and define recesses into which the interconnected jaw members can be swung so as to be nested in the handles or, alternatively, into which the interconnected jaw members can be retracted so as to be partially contained within the handles. The handles have forward portions interconnected by a link which, in an open position of the handles, is positioned between the handle pivots and the jaw pivot. For a given angle of swing of the handles, the jaws are moved through a smaller angle, i.e., a substantial mechanical advantage is obtained.Type: GrantFiled: September 21, 1998Date of Patent: December 21, 1999Assignee: SOG Specialty Knives, Inc.Inventor: Spencer Frazer

Patent number: 5957013Abstract: Opposing jaw members of a hand tool are interconnected by a first pivot and have working end portions swingable toward and away from each other. The assembly of interconnected jaws is itself pivotally mounted on one or more handles that define a housing for the jaw assembly. The jaw assembly is swingable relative to the housing between a compact, closed position in which the jaws are concealed and an open, extended, working position in which the jaws are exposed. A second handle pivoted to the first handle can be manipulated to effect relative movement of the jaws when the jaws are in the open position.Type: GrantFiled: November 2, 1998Date of Patent: September 28, 1999Assignee: SOG Specialty Knives, Inc.Inventor: Spencer Frazer

The assembly of interconnected jaws is itself pivotally mounted on one or more handles that define a housing for the jaw assembly. The jaw assembly is swingable relative to the housing about a second pivot offset from the first pivot, between a compact, closed position in which the jaws are concealed and an open, extended, working position in which the jaws are exposed. A second handle pivoted to the first handle can be manipulated to effect relative movement of the jaws when the jaws are in the open position.Type: GrantFiled: May 16, 1996Date of Patent: November 3, 1998Assignee: SOG Specialty Knives, Inc.Inventor: Spencer Frazer

Patent number: 5267366Abstract: Jaw members are pivoted together such that cooperating working end portions of the jaw members are movable toward and away from each other. The jaw members have tang or butt portions extending opposite the pivot from the working end portions. Such butt portions are, in turn, pivoted to elongated handles which are channel shaped and define a recess between them into which the interconnected jaw members can be swung so as to be nested in the handles. The pivots connecting the butt portions of the jaw members to the handles are not coaxial but rather are mutually oblique in such a manner that swinging of the jaw members from the retracted or nested position to the working position necessarily results in spreading the handles relatively apart. Similarly, movement of the jaw members from the projected position to the retracted or nested position automatically swings the handles together. Mechanism is provided to interconnect the handles automatically when the jaw members are retracted.Type: GrantFiled: May 27, 1992Date of Patent: December 7, 1993Inventor: Spencer Frazer

Patent number: 4369857Abstract: A loudspeaker and horn combination having desirable sound clarity characteristics and having a desirable per unit of electric power input to per unit of sound output ratio can be constructed using a horn body of one or more parts of a rigid, closed cell polyurethane foam material having a smooth exterior skin or surface shaped so as to include an internal horn cavity. A speaker is located so that its diaphragm extends across an entrance end of the cavity. The cavity is shaped in a bilaterally symmetrical manner so as to include a sound chamber region adjacent to and leading from the speaker diaphragm, this sound chamber region having a restricted throat located intermediate its ends and having a continuous curvature between its ends, a flare region diverging outwardly from the end of the sound cavity region remote from the speaker and a transitional region located generally between the flare and sound cavity regions so as to connect the adjacent surfaces of these regions.Type: GrantFiled: January 22, 1981Date of Patent: January 25, 1983Assignee: The Kind Horn CompanyInventors: Spencer Frazer, Steven P.
