Publication number: 20040063517Abstract: A golf ball is described that includes a spherical core, an inner cover or mantle layer, and an outer cover layer. A wide array of ionomeric materials are noted for use in the various cover layers. The mantle and the outer cover layers exhibit different Shore D hardness values and at least one of the layers includes a heavy weight filler material to enhance the interior perimeter weight of the ball. In several particular versions of the golf balls, the filler material is present in an amount of at least 10% by weight based upon the weight of the layer or layers within which the filler material is incorporated.Type: ApplicationFiled: September 11, 2003Publication date: April 1, 2004Applicant: Spalding Sports Worldwide, Inc.Inventors: Mark L.

Publication number: 20040053706Abstract: Disclosed herein is a golf ball with a cover or mantle, or both, formed from an isophthalic acid polyamide composition and a method of making the same. In one embodiment, the golf ball has a cover which contains a combination of an isophthalic acid polyamide component and an ionomeric component or a non-ionomeric terpolymer component. The cover composition has excellent durability and resistance to cracking, even at cold temperatures. The nylon-ionomer blend is a useful substitute for an ionomer golf ball cover, particularly when a low spin golf ball is desired.Type: ApplicationFiled: September 11, 2003Publication date: March 18, 2004Applicant: Spalding Sports Worldwide, Inc.Inventors: Thomas J.

Publication number: 20030232659Abstract: A golf club head with low peripheral and rearward weighting includes C-shaped and annular weights connected with at least one of the rear and bottom surfaces, respectively, of the head. The weighting within the peripheral weights is adjustable between the heel, rear, and toe portions of the head to customize the weight distribution of the head in accordance with a golfer's swing. The added weight and its orientation increases the moment of inertia of the head and reduces the rotation thereof.Type: ApplicationFiled: March 4, 2003Publication date: December 18, 2003Applicant: Spalding Sports Worldwide, Inc.Inventors: Steven J.

Patent number: 6616550Abstract: The present invention is directed to improved regulation multi-layer golf balls. A smaller and lighter core is produced and metal particles, or other heavy weight filler materials, are included in the cover compositions. The resulting molded golf ball exhibits enhanced interior perimeter weighting. Preferably, the particles are included in a relatively thick inner cover layer (or mantle) of a solid, three-piece multi-layered golf ball. The size and weight of the core is reduced in order to produce an overall golf ball which meets, or is less than, the 1.62 ounce maximum weight limitation specified by the United States Golf Association. The combination of the present invention produces a golf ball with an increased moment of inertia and/or a greater radius of gyration and thus generates lower spin. This results in a golf ball exhibiting enhanced distance without substantially effecting the feel and durability characteristics of the ball.Type: GrantFiled: August 22, 2001Date of Patent: September 9, 2003Assignee: Spalding Sports Worldwide, Inc.Inventors: R. Dennis Nesbitt, John L. Nealon, Mark L. Binette, Michael J. Sullivan

Patent number: 6609410Abstract: A high strain rate tester for elastomeric materials used in sports balls includes a base on which a sample of the material is mounted and a striker which delivers an impact to the sample, preferably in the vertical direction. A load cell adjacent to the sample measures the reaction force of the impact from the sample and an optical detector measures the displacement of the sample in the vertical direction. The force and displacement measurements are processed to determine the time dependent strain of the material.Type: GrantFiled: September 26, 2001Date of Patent: August 26, 2003Assignee: Spalding Sports Worldwide, Inc.Inventors: John D. Axe, Vincent J. Simonds, Thomas A. Veilleux

Publication number: 20030157995Abstract: Laminated striking face inserts for golf clubs are characterized by explosion bonding of the layers of the laminate. The outer layers are of a substantially high strength and density material and the center layer is of relatively lower strength and density material. Explosion bonding results in a laminated face plate or insert in which the yield strength of the laminate is similar to the full strength characteristics of the materials used in the laminate.Type: ApplicationFiled: February 10, 2003Publication date: August 21, 2003Applicant: Spalding Sports Worldwide, Inc.Inventor: Steven J.

Publication number: 20030153397Abstract: A set of golf clubs is characterized by club heads having striking face inserts at least one of which varies in thickness, density, and/or material from the other inserts so that the heads have different centers of gravity. Preferably the long irons in the set have a lower center of gravity (because of thinner or less dense inserts) to increase the trajectory of a struck golf ball. The short irons have a higher center of gravity to reduce the trajectory of a struck golf ball.Type: ApplicationFiled: August 26, 2002Publication date: August 14, 2003Applicant: Spalding Sports Worldwide, Inc.Inventors: Ryan Roach, Steven J.

Publication number: 20030153408Abstract: A golf ball having a core comprising metallocene catalyzed polyolefin and having a PGA compression of no greater than about 85 and a multi-layered cover disposed about the core having a thickness of at least about 3.6 mm is described. A golf ball is also described having a core with a PGA compression of no greater than about 85 and a multi-layer cover with a thickness of at least 3.6 mm (0.142 inches) and a Shore D hardness of at least about 60 wherein at least one layer of the multi-layered cover comprises a high acid ionomer resin having at least 16% by weight of an alpha, beta-unsaturated carboxylic acid. The combination of a core with a thick, relatively hard multi-layer cover results in a ball having better distance than conventional golf balls having a comparable coefficient of restitution.Type: ApplicationFiled: June 5, 2002Publication date: August 14, 2003Applicant: Spalding Sports Worldwide, Inc.Inventors: Mark L.

Publication number: 20030148823Abstract: A golf ball is provided having a controlled variable moment of inertia. The golf ball includes a core defining at least one hollow channel. At least one movable weight is located within each hollow channel. The end of the hollow channel at the outer edge of the core is enclosed with a plug. The movable weight and plug may each further include a magnet or the hollow channel may include a placement member such as a spring to control the movement of the weight. When the present golf ball is struck, the spin rate forces the weights to move from the interior of the core outwardly towards the outer edge of the core, thereby varying the moment of inertia of the golf ball. A method of manufacturing the present golf ball is also provided. The golf ball also significantly reduces hooks and slices due to the gyroscopic effect of the moving weight(s) to the outer edge of the core.Type: ApplicationFiled: December 13, 2001Publication date: August 7, 2003Applicant: SPALDING SPORTS WORLDWIDE, INC.Inventors: R.
