Definitions
- the present invention relates to golf balls and, more particularly, to improved golf balls having low spin rates.
- the improvement in the golf balls results from a combination of a relatively soft core, and a hard cover made from blends of one or more specific hard, high stiffness ionomers.
- the combination of a soft core and a hard cover leads to an improved golf ball having a lower than anticipated spin rate while maintaining the resilience and durability characteristics necessary for repetitive play.
- the present invention relates to golf balls comprising one or more mantle layers formed from a metal, ceramic, or a composite material.
- the golf balls may comprise an optional polymeric outer cover and/or an inner polymeric hollow sphere substrate.
- the spin rate is further reduced by decreasing the weight of the soft core while maintaining core size and by increasing the thickness of the cover.
- the larger, less dense finished ball exhibits lower spin rates after club impact than conventional balls.
- Spin rate is an important golf ball characteristic for both the skilled and unskilled golfer
- High spin rates allow for the more skilled golfer, such as PGA professionals and low handicap players, to maximize control of the golf ball This is particularly beneficial to the more skilled golfer when hitting an approach shot to a green
- the more skilled golfer generally prefers a golf ball exhibiting high spin rate properties
- a high spin golf ball is not desirous by all golfers, particularly high handicap players who cannot intentionally control the spin of the ball
- less skilled golfers have, among others, two substantial obstacles to improving their game slicing and hooking
- an unintentional side spin is often imparted which sends the ball off its intended course
- the side spin reduces one's control over the ball as well as the distance the ball will travel As a result, unwanted strokes are added to the game
- a more efficient ball for the less skilled player is a golf ball that exhibits low spin properties
- the low spin ball reduces slicing and hooking and enhances roll distance for the amateur golfer
- the present inventors have addressed the need for developing a golf ball having a reduced spin rate after club impact, while at the same time maintaining the durability, playability and resiliency characteristics needed for repetitive use
- the reduced spin rate golf ball of the present invention meets the rules and regulations established by the United States Golf Association (U S G A )
- the U S G A has set forth five (5) specific regulations to which a golf ball must conform
- the U S G A rules require that a ball be no smaller than 1 680 inches in diameter
- a golf ball can be as large as desired so long as it is larger than 1.680 inches in diameter and so long as the other four (4) specific regulations are met.
- the U.S.G.A. rules also require that balls weigh no more than
- Top-grade golf balls sold in the United States may be generally classified as one of two types: two-piece or three-piece balls.
- the two-piece ball exemplified by the balls sold by Spalding & Evenflo Companies, Inc. (the assignee of the present invention through its wholly owned subsidiary, Lisco, Inc.) under the trademark TOP-FLITE, consists of a solid polymeric core and a separately formed outer cover.
- the so-called three-piece balls exemplified by the balls sold under the trademark TITLEIST by the Acushnet Company, consist of a liquid (e.g., TITLEIST TOUR 384) or solid (e.g., TITLEIST DT) center, elastomeric thread windings about the center, and a cover.
- Spalding's two-piece golf balls are produced by molding a natural (balata) or synthetic (i.e. thermoplastic resin such as an ionomer resin) polymeric cover composition around a preformed polybutadiene (rubber) core. During the molding process, the desired dimple pattern is molded into the cover material.
- balata natural (balata) or synthetic (i.e. thermoplastic resin such as an ionomer resin) polymeric cover composition around a preformed polybutadiene (rubber) core.
- a color pigment or dye and, in many instances, an optical brightener are added directly to the generally "off white” colored polymeric cover composition prior to molding
- this process eliminates the need for a supplemental pigmented painting step in order to produce a white or colored (notably orange, pink and yellow) golf ball
- Spalding is the leading manufacturer of two-piece golf balls in the world Spalding manufactures over sixty (60) different types of two-piece balls which vary distinctly in such properties as playability (i e spin rate, compression, feel, etc ), travel distance (initial velocity, C O R , etc ), durability (impact, cut and weather resistance) and appearance (i e whiteness, reflectance, yellowness, etc ) depending upon the ball's core, cover and coating materials, as well as the ball's surface configuration (i e dimple pattern) Consequently, Spaldmg's two-piece golf balls offer both the amateur and professional golfer a variety of performance characteristics to suit an individual's game
- the initial velocity of two-piece and three-piece balls is determined mainly by the coefficient of restitution of the core
- the coefficient of restitution of the core of wound (i e three-piece) balls can be controlled within limits by regulating the winding tension and the thread and center composition
- the coefficient of restitution of the core is a function of the properties of the elastomer composition from which it is made
- the cover component of a golf ball is particularly influential in affecting the compression (feel), spin rates (control), distance (C O R ), and durability (i e impact resistance, etc ) of the resulting ball
- Various cover compositions have been developed by Spalding and others in order to optimize the desired properties of the resulting golf balls Over the
- U S Patent No 985,741 to Harvey discloses the use of a glass shell
- Other artisans described incorporating glass microspheres within a golf ball such as in U S Patent No 4,085,937 to Schenk
- the use of polymeric materials in intermediate layers within a golf ball is more popular than, for instance, the use of glass or other vitreous material
- Kempshall disclosed the use of an interior coating layer of plastic in U S Patent Nos 696,887 and 701 ,741 Kempshall further described incorporating a fabric layer in conjunction with a plastic layer in U S Patent Nos 696,891 and 700,656
- Numerous subsequent approaches were patented in which a plastic inner layer was incorporated in a golf ball
- a thermoplastic outer core layer was disclosed in U S Patent No 3,534,965 to Harrison Inner synthetic polymeric layers are noted in U S Patent No.
- the spin rate of the ball is further reduced by increasing the thickness of the cover and/or decreasing the weight and softness of the core
- increased size of the ball over the years golf ball manufacturers have generally produced golf balls at or around the minimum size and maximum weight specifications set forth by the U.S.G.A.
- golf ball manufacturers have generally produced golf balls at or around the minimum size and maximum weight specifications set forth by the U.S.G.A.
- oversized, overweight (and thus unauthorized) golf balls have been on sale for use as golf teaching aids (see U.S. Patent 3,201 ,384 to Barber).
- Oversized golf balls are also disclosed in New Zealand Patent No. 192,618 dated January 1 , 1980, issued to a predecessor of the present assignee.
- This patent teaches an oversize golf ball having a diameter between 1.700 and 1.730 inches and an oversized core of resilient material (i.e. about 1.585 to 1.595 inches in diameter) so as to increase the coefficient of restitution.
- the patent discloses that the ball should include a cover having a thickness less than the cover thickness of conventional balls (i.e. a cover thickness of about 0.050 inches as opposed to 0.090 inches for conventional two-piece balls).
- golf balls made by Spalding in 1915 were of a diameter ranging from 1.630 inches to 1.710 inches. As the diameter of the ball increased, the weight of the ball also increased. These balls were comprised of covers made up of balata/gutta percha and cores made from solid rubber or liquid sacs and wound with elastic thread.
- LYNX JUMBO Golf balls known as the LYNX JUMBO were also commercially available by Lynx in October, 1979. These balls had a diameter of 1.76 to 1.80 inches.
- the LYNX JUMBO balls met with little or no commercial success.
- the balls consisted of a core comprised of wound core and a cover comprised of natural or synthetic balata.
- An object of the present invention is to produce a U.S.G.A. regulation golf ball having improved low spin properties while maintaining the resilience and durability characteristics necessary for repetitive play.
- the present invention is directed to improved golf balls having a low rate of spin upon club impact
- the golf balls comprise a soft core and a hard cover
- the hard cover may be sized to be larger than conventional diameters
- the low spin rate enables the ball to travel a greater distance
- the low spin rate provides the less skilled golfer with more control This is because the low spin rate decreases undesirable side spin which leads to slicing and hooking
- the combination of a hard cover and a soft core provides for a ball having a lower than anticipated spin rate while maintaining high resilience and good durability
- the present invention provides a low spin golf ball comprising a core that includes a core component and a spherical mantle encompassing the core component
- the mantle comprises a polymeric material and a reinforcing material dispersed throughout the polymeric material

- the present invention relates to the development of a golf ball having a low spin rate as a result of combining a relatively soft core and a hard cover.
- the present invention low spin golf balls feature a relatively soft interior core or core component. That is, the core and any interior mantle layers, collectively, exhibit a Riehle compression of at least about 75 and preferably from about 75 to about 160. Most preferably, the Riehle compression of the core is from about 80 to about 90.
- the present invention low spin golf balls also feature a relatively hard cover. That is, the cover exhibits a Shore D hardness of at least about 65.
- a lower spin rate after club impact contributes to straighter shots when the ball is mis-hit, greater efficiency in flight, and a lesser degree of energy loss on impact with the ground, adding increased roll or distance.
- the spin rate is still further decreased.
- the ball even though of larger diameter, uses substantially the same size core as a standard golf ball, the difference in size is provided by the additional thickness in the cover of the ball. This larger, low spin ball produces even greater control and flight efficiency than the standard size ball embodiment of the present invention.
- the golf balls preferably utilize a solid core or core component. It will be understood that the low spin golf balls may instead feature a hollow interior or hollow core.
- all preferred embodiment golf balls comprise one or more mantle layers that comprise one or more metals, ceramics, or composite materials. Details of the materials, configuration, and construction of each component in the preferred embodiment golf balls are set forth below

- all covers such as cover 10, may be of a single or a multiple layer construction. Details of the materials, configuration, and construction of each component in the preferred embodiment golf balls are set forth below.
- Riehle compression is a measurement of the deformation in thousandths of inches under a fixed static load of 200 pounds (a Riehle compression of 47 corresponds to a deflection under load of 0.047 inches).
- Coefficient of restitution (C.O.R.) is measured by firing the resulting golf ball in an air cannon at a velocity of 125 feet per second against a steel plate which is positioned 12 feet from the muzzle of the cannon. The rebound velocity is then measured. The rebound velocity is divided by the forward velocity to give the coefficient of restitution.
- Shore D hardness is measured in accordance with ASTM Test D- 2240.
- the core used in the present invention golf ball is a specially produced softened polybutadiene elastomeric solid core having a conventional diameter of about 1.540 to 1.545 inches.
- the core is produced from a composition comprising a base elastomer selected from polybutadiene and mixtures of polybutadiene with other elastomers, at least one metallic salt of an unsaturated carboxylic acid (a co-crosslinking agent), and free radical initiator (a co-crosslinking agent).
- a suitable and compatible modifying ingredient including, but not limited to metal activators, fatty acids, fillers, polypropylene powder and other additives may be included.
- the metallic salt of an unsaturated carboxylic acid is included in the core compositions in order to produce the degree of core softness and weight desired.
- the composition of the core is adjusted so that the molded finished ball falls within the weight parameters set forth by the U.S.G.A. Since the finished golf balls must still meet the U.S.G.A. weight limitation of 1.620 ounces, the core component of the larger and thicker covered balls are designed to be not only softer, but also lighter in weight.
- the specific gravity of the core is less than that of a standard core since the larger ball must weigh the same as a standard ball.
- the core generally weighs about 36 to 37 grams for a standard sized finished ball and about 33 to 34 grams for an oversized finished ball.
- the core composition produces a softer molded core which still maintains the resilience (C.O.R.), compression (hardness) and durability characteristics required.
- the overall core has a PGA compression of about 0 to 85, and preferably in the range of about 10 to about 70. Its Riehle compression is about 75 or more, preferably in the range of about 75 to about 160, and the resilience of the core is about 0.760 to 0.780.
- the specially produced core compositions and resulting molded cores of the present invention are manufactured using relatively conventional techniques.
- the core compositions of the invention may be based on polybutadiene, and mixtures of polybutadiene with other elastomers.
- the base elastomer have a relatively high molecular weight.
- the broad range for the molecular weight of suitable base elastomers is from about 50,000 to about 500,000.
- a more preferred range for the molecular weight of the base elastomer is from about 100,000 to about 500,000.
- cis-polybutadiene is preferably employed, or a blend of cis-polybutadiene with other elastomers may also be utilized. Most preferably, cis-polybutadiene having a weight-average molecular weight of from about 100,000 to about 500,000 is employed. Along this line, it has been found that the high cis-polybutadiene manufactured and sold by Shell - H

- the acid component is either acrylic or methacrylic acid
- the carboxylic acid salt such as zinc diacrylate
- the unsaturated carboxylic acids and metal salts thereof are generally soluble in the elastomeric base, or are readily dispersible

- Vacuum coating is another category of processes for depositing metals and metal compounds from a source in a high vacuum environment onto a substrate, such as the spherical substrate used in several of the preferred embodiment golf balls.
- Three principal techniques are used to accomplish such deposition: evaporation, ion plating, and sputtering. In each technique, the transport of vapor is carried out in an evacuated, controlled environment chamber and, typically, at a residual air pressure of 1 to 10 "5 Pascals.
- vapor is generated by heating a source material to a temperature such that the vapor pressure significantly exceeds the ambient chamber pressure and produces sufficient vapor for practical deposition.
- a substrate such as the inner spherical substrate utilized in the preferred embodiment golf balls, it must be rotated and translated over the vapor source.
- Deposits made on substrates positioned at low angles to the vapor source generally result in fibrous, poorly bonded structures.
- Deposits resulting from excessive gas scattering are poorly adherent, amorphous, and generally dark in color.
- the highest quality deposits are made on surfaces nearly normal or perpendicular to the vapor flux. Such deposits faithfully reproduce the substrate surface texture. Highly polished substrates produce lustrous deposits, and the bulk properties of the deposits are maximized for the given deposition conditions.
- source material should be heated to a temperature so that its vapor pressure is at least 1 Pascal or higher.
- Deposition rates for evaporating bulk vacuum coatings can be very high.
- Commercial coating equipment can deposit up to 500,000 angstroms of material thickness per minute using large ingot material sources and high powered electron beam heating techniques
- the directionality of evaporating atoms from a vapor source generally requires the substrate to be articulated within the vapor cloud To obtain a specific film distribution on a substrate, the shape of the object, the arrangement of the vapor source relative to the component surfaces, and the nature of the evaporation source may be controlled
- evaporation sources most elemental metals, semi- conductors, compounds, and many alloys can be directly evaporated in vacuum
- the simplest sources are resistance wires and metal foils They are generally constructed of refractory metals, such as tungsten, molybdenum, and tantalum
- the filaments serve the dual function of heating and holding the material for evaporation

- the crucible materials are usually refractory metals, oxides, and nitrides, and carbon Heating can be accomplished by radiation from a second refractory heating element, by a combination of radiation and conduction, and by radial frequency induction heating
- Electron beam heating provides a flexible heating method that can concentrate heat on the evaporant Portions of the evaporant next to the container can be kept at low temperatures, thus minimizing interaction
- Two principal electron guns in use are the linear focusing gun, which uses magnetic and electrostatic focusing methods, and the bent-beam magnetically focused gun
- Another technique for achieving evaporation is continuous feed high rate evaporation methods
- High rate evaporation of alloys to form film thicknesses of 100 to 150 micrometers requires electron beam heating sources in large quantities of evaporant

- the source of ions may be an ion beam or a plasma discharge into which the material can be bombarded is immersed.
- a source of coating material called a target is placed in a vacuum chamber which is evacuated and then back filled with a working gas, such as Argon, to a pressure adequate to sustain the plasma discharge.
- a working gas such as Argon
- Sputter coating chambers are typically evacuated to pressures ranging from 0.001 to 0.00001 Pascals before back filling with Argon to pressures of 0.1 to 10 Pascals.
- the intensity of the plasma discharge, and thus the ion flux and sputtering rate that can be achieved, depends on the shape of the cathode electrode, and on the effective use of a magnetic field to confine the plasma electrons.
- the deposition rate in sputtering depends on the target sputtering rate and the apparatus geometry. It also depends on the working gas pressure, since high pressures limit the passage of sputtered flux to the substrates.
- Ion plating may also be used to form one or more metal mantle layers in the golf balls of the present invention.
- Ion plating is a generic term applied to atomistic film deposition processes in which the substrate surface and/or the depositing film is subjected to a flux of high energy particles (usually gas ions) sufficient to cause changes in the interfacial region or film properties Such changes may be in the film adhesion to the substrate, film morphology, film density, film stress, or surface coverage by the depositing film material
- Ion plating is typically done in an inert gas discharge system similar to that used in sputtering deposition except that the substrate is the sputtering cathode and the bombarded surface often has a complex geometry
