Patent number: 7597634Abstract: A method of assembly of construction and assembly of golf club head parts used to manufacture golf club heads primarily composed of strong plastic materials that can be formed by injection plastic molding processes in a minimum of two parts. Draft is practical for both molded parts to simplify mold making. A preferred plastic is polycarbonate. Internal reinforcement elements are designed and arranged to provide structural features to facilitate assembly and improve strength of bonds. Internal reinforcement elements may be molded as separate parts to join with the face and shell structure. A hosel, which is not considered part of the shell and which may be made of plastic or metal, is bonded into the golf club head parts described.Type: GrantFiled: November 14, 2006Date of Patent: October 6, 2009Assignee: Origin, Inc.Inventors: Frank D.

Publication number: 20090131196Abstract: Improved golf club heads indicating the location of an optimum hit point on the striking face for maximum shot distance of any hit location on the face (“maximum distance spot”, called MD) and an indication of a second optimum hit point giving best distance, with the condition of minimum or no change of torque caused feel as perceived by the golfer at impact (“best feel spot,” called BF) are disclosed. Methods to locate these optimum locations are described. It has been widely assumed and believed that these two points have the same location. The present inventors have found that this is not true. The principal application is to “wood” type golf clubs designed to hit golf balls from a tee, but can provide useful information for clubs hitting balls from the ground. The indication of MD and BF locations on the club face may take any of various forms.Type: ApplicationFiled: February 28, 2007Publication date: May 21, 2009Applicant: Origin, Inc.Inventors: Frank D.

Publication number: 20030027662Abstract: A golf club head is composed of elastic substructures having moderate elasticity and consisting of a face, outer shell, and inner structure in which said elastic substructures that cooperate so as to provide larger impulses to the ball at impact, due to combined elastic properties of the club face for hits at all locations on the face. This allows better distance of shots when loft angle and other design details are appropriately chosen. The structure also minimizes variations of angular orientation of the face surface at the point of impact for all such hits. The elastic substructures can take several forms such as an internal elastic support around the periphery of the face structure, an internal support for the central part of the face structure, and an elastic structure attached to the front side of the face structure, an elastic outer shell, and their combinations.Type: ApplicationFiled: August 1, 2002Publication date: February 6, 2003Inventors: Frank D.

Patent number: 6319150Abstract: A face wall for the hitting face of a golf club head is supported on a hollow structural shell. The face wall is formed to realize maximum face strength with minimum face mass. This is accomplished by varying the thickness of the face wall so it is thickest in the general vicinity of the face center and becomes thinner toward the edges of the face. This allows the club head to weigh less, incorporate a large face area and adequate strength while maintaining high moments of inertia of the head.Type: GrantFiled: May 25, 1999Date of Patent: November 20, 2001Inventors: Frank D. Werner, Richard C. Greig

Patent number: 6152833Abstract: A golf club head for a wood club type that has a thick, light weight, low density face wall supported to its rear by a hollow shell structure. The shell structure supports the face wall around the periphery of the face wall, and a club shaft is attached suitably to the rear of the front face of the face wall. The face wall preferably has a club face area greater than 5.3 square inches, and a weight not exceeding half of the total club head weight.Type: GrantFiled: June 15, 1998Date of Patent: November 28, 2000Assignee: Frank D. WernerInventors: Frank D. Werner, Richard C. Greig

Patent number: 6139445Abstract: Golf club heads are disclosed which have face surface shapes which are designed so as to reduce the scatter of the points where the ball stops after a hit, as compared to face surface shapes of prior art. This is accomplished by use of optimum face surface shapes which respect the USGA requirement for no degree of concavity. The face surface shapes disclosed are different in upward directions from the hit center to the face surface shapes in downward directions.Type: GrantFiled: August 14, 1998Date of Patent: October 31, 2000Assignee: Frank D. WernerInventors: Frank D. Werner, Richard C. Greig

Patent number: 5380010Abstract: A golf club "wood" of hollow construction includes a shell or wall which is attached to the back side of the face plates and extends rearwardly to a mass mounted as part of the head. The shell or wall is relatively straight in the load bearing direction and is preferably corrugated to suppress buckling failure. The shell or wall may be cast, or if desired thinner sections may be made of sheet material and assembled to support the face by means of welding, silver brazing, or for certain materials, gluing in place. An outer cover may be added to preserve an approximately traditional external shape or to permit other freedom of design of the external shape. The cover is lightweight construction such as fiber-reinforced plastic, or a very rigid foam plastic material.Type: GrantFiled: October 28, 1993Date of Patent: January 10, 1995Assignee: Frank D.

Patent number: 5366223Abstract: A golf club, specifically a driver, has a roughly elliptical face shape oriented so that the long axis of the ellipse is tilted upward at the toe at an angle of 20 degrees or more. This causes better agreement between the hit pattern and the perimeter of the club face, with the important result of minimizing the percentage of impacts which are not completely on the face of the club. This arrangement is for drivers since no other clubs are normally used with a tee and a consequence is that tilting the ball strike region of the face is not helpful for such clubs.Type: GrantFiled: October 28, 1993Date of Patent: November 22, 1994Assignee: Frank D.

Patent number: 5156853Abstract: An apparatus for repairing breaks in safety glass, such as that found on automotive windshields, includes a self-contained, small fixture which can be secured to the windshield and centered on the break. The fixture includes connections for applying a vacuum source for evacuating the break, and for connecting a self-contained and self-supported measured quantity of resin to the fixture so the resin will enter the break while the break remains under a vacuum. The introduction of the resin into the break is thus enhanced, because the break is under vacuum. When vacuum is released, pressure may be applied to the resin to force it into the break to completely fill the break and provide for a visually acceptable repair. Curing of resins can then be carried out in a conventional manner.Type: GrantFiled: September 18, 1991Date of Patent: October 20, 1992Inventors: Frank D. Werner, Richard C. Greig
