Abstract
Description
- This application is a divisional application of co-pending U.S. patent application No. 09/584,623, filed on May 31, 2000.
- [Not Applicable]
- 1. Field of the Invention
- The present invention relates to a golf club. More specifically, the present invention relates to a golf club with a weighting member composed of multiple materials.
- 2. Description of the Related Art
- Golf club designs are constantly evolving with the primary purpose to improve a golfer's performance. While the improvements may address a number of areas, a designer strives to design a more forgiving golf club. Forgiveness in a golf club may be achieved by shifting the center-of-gravity of a golf club to a desirable location, and creating a larger moment of inertia.
- It is difficult to increase forgiveness in a golf club head composed of a homogeneous or monolithic material, such as stainless steel, since there is a limit on the overall weight of a golf club acceptable to the typical golfer. To overcome this difficulty, designers have resorted to combining different materials (high density and low density) to achieve the desired center-of gravity and large moment of inertia. A very high-density material provides a designer with the greatest freedom in improving the performance of a golf club head since less volume is needed to achieve the proper weighting. The most economical, commercially available material with a very high density is tungsten, which has a density of 19.3 grams per cubic centimeter.
- One challenge in using heterogeneous materials is the ability to join the materials together in a golf club head. Numerous techniques have been created by the golf industry to join heterogeneous materials in a golf club head. One example is the GREAT BIG BERTHA® TUNGSTEN-TITANIUM™ irons, developed by the Callaway Golf Company of Carlsbad, Calif., which used a screw to attach a tungsten block to the rear and sole of a titanium iron. Another example is the GREAT BIG BERTHA® TUNGSTEN-INJECTED™ HAWK EYE® irons, also developed by the Callaway Golf Company, which feature an internal cavity with tungsten pellets in a solder, as set forth in co-pending U.S. patent application No. 09/330,292, for an Internal Cavity Tungsten Titanium Iron , filed on Jun. 11, 1999. An example of a wood is the GREAT BIG BERTHA® HAWK EYE® drivers and fairway woods, also developed by the Callaway Golf Company, which use a tungsten screw in the sole of a titanium club head body. Other techniques use adhesives to join the materials, press fit the materials, braze the materials, or structurally hold one material piece within another material piece using undercuts or pockets.
- For the most part, these techniques require a precisely machined weighting piece to fit within a precise location on a golf club head. The most economical method is to cast a golf club head body with a cavity for the weighting piece and attaching the weighting piece with a screw. However, casting tolerance are low, and require either machining of the cavity itself, or machining of the weighting piece to fit each cavity. The use of softer materials is undesirable since this creates difficulty in finishing the final product due to smearing of such soft materials during grinding of the golf club head.
- Further, a co-casting process, where the weighting piece is incorporated in the mold prior to pouring the base metal, is very problematic depending on the materials since the weighting piece is relatively cold when the hot liquid base metal is cast around it causing thermal shock. Also, thermal expansion mismatch of materials is a problem with co-casting of heterogeneous materials. Other problems arise during reshafting, where the golf club head is heated to remove the shaft. Such heating will result in low melting temperature materials (epoxies and solder) to flow, resulting in the possible movement of weighting pieces.
- The present invention allows for a golf club head to be easily weighted without precisely machined weighting components. The present invention is able to accomplish this by forming a weighting member composed of a multi-component material into the golf club head by applying pressure to the multi-component material while it is in a cavity of the golf club head.
- The most general aspect of the present invention is a golf club head with a body and a weighting member. The body has a striking plate, a heel end a toe end and a cavity. The weighting member is composed of a multi-component material and is disposed in the cavity of the body.
- Another aspect of the present invention is a cavity back golf club head having a body and a weighting member. The body has a striking plate, a toe end, a heel end and a main rear cavity opposite the striking plate. A top wall, a bottom wall, a heel wall and a toe wall define the main rear cavity. The bottom wall has a second cavity with a predetermined configuration. The weighting member is disposed within the second cavity and occupies the entire cavity. The weighting member is composed of a multi-component material.
- Yet another aspect is a method for manufacturing a golf club head. The method includes introducing a multi-component powder/pellet mixture into a cavity on a body of a golf club head, and applying a predetermined amount of force to the multi-component powder/pellet mixture to compact the multi-component powder/pellet mixture within the cavity and form a weighting member. The multi-component powder/pellet mixture may also be heated to a predetermined temperature for hot pressing of the multi-component powder/pellet mixture within. The predetermined temperature is above or closest to the melting temperature of one component of the multi-component powder/pellet mixture.
- The multi-component powder/pellet mixture may be composed of a high-density component and a binder component. One variation of the multi-component powder/pellet mixture may be composed of tungsten and tin, or alternatively composed of tungsten and a tin bismuth material.

- As shown in FIGS.1-7, a golf club head is generally designated 20. The
golf club head 20 is a cavity-back iron with abody 22 and aweighting member 24. Thegolf club head 20 has aheel end 26, atoe end 28 and a sole 29. On the front of thebody 22 is astriking plate 30 that has a plurality ofscorelines 32 therein. Ahosel 34 for receiving ashaft 36 is located on theheel end 26 of thegolf club head 20. The rear of thegolf club head 20 has amain cavity 38 that is defined by atop wall 40, abottom wall 42, aheel wall 44 and atoe wall 46. Thegolf club head 20 also has an optional undercutrecess 48 circumventing and openly exposed to themain cavity 38. - The
weighting member 24 is composed of multiple component powder or pellet mixture that is pressed within a cavity 25 (shown in FIG. 11) of thebody 22. Thecavity 25 is preferably open to the sole 29 and thebottom wall 42. However those skilled in the pertinent art will recognize that thecavity 25, and hence theweighting member 24, may be disposed in numerous locations to provide a desired affect. As shown in FIG. 7, theweighting member 25 locates a large percentage of the mass of thegolf club head 20 in the lower center of thegolf club head 20 thereby lowering the center of gravity of thegolf club head 20 to make it more forgiving for a golfer. - An alternative embodiment of the golf club head20 a of the present invention is illustrated in FIGS. 8 and 9. The golf club head 20 a is a blade-style iron as compared to the cavity-back iron of FIGS. 1-7. The golf club head 20 a of FIGS. 8 and 9 does not have a
cavity 38, nor does it have an undercut 48. Theweighting member 24 a is disposed annularly about the rear 39 of thebody 22. Further, the cavity 25 a containing theweighting member 24 a is open only to the rear 39 and not the sole as in the previous embodiment. Theannular weighting member 24 a allows for the blade style golf club head 20 a to have perimeter weighting similar to a cavity-back iron, and thus the forgiveness of a cavity-back iron while having the traditional appearance of a blade iron. Theannular weighting member 24 a will occupy a greater volume of the golf club head 20 a than theweighting member 24 of FIGS. 1-7, and thus will also have a greater percentage of the mass of the golf club head 20 a. The weighting member of the present invention may occupy various contoured cavities of golf club heads due to its unique manufacturing method. - FIG. 10 illustrates a flow chart of the process of the present invention for producing a
golf club head 20 or 20 a with aweighting member process 200 begins with providing agolf club head 20, preferably prepared by a conventional investment casting process atblock 202. However, those skilled in the pertinent art will recognize that thegolf club head 20 or 20 a may be prepared through other techniques well know in the golf industry, such as forging. Thegolf club head 20 may be composed of stainless steel, titanium, titanium alloys, zirconium, zirconium alloys, copper, nickel, cobalt alloys, or like materials. Thegolf club head 20 is cast to have acavity 25, as shown in FIG. 11, and preferably has alip 51, as shown in FIG. 12, for containing the mixture. Thelip 51 is removed during the finishing process. Thecavity 25 has a predetermined volume according to the amount of mass needed from theweighting member 24 for thegolf club head 20. Atblock 204, the precursor powder materials for the multiple component powder or pellet mixture are compacted for placement into thecavity 25. The mixture may be composed of powders, pellets or a mixture thereof. The precursor powder or pellet materials are composed of a high-density component in various particle sizes (ranging from 1.0 mm to 0.01 mm) for achieving low porosity for theweighting member 24. The preferred high-density component is tungsten which has a density of 19.3 grams per cubic centimeter (g/cm3), however other high-density materials may be used such as molybdenum (10.2 g/cm3), tantalum (16.7 g/cm3), platinum (21.4 g/cm3), gold (19.3 g/cm3), silver (10.3 g/cm3), and the like. Additionally, high-density ceramic powders may be utilized as the high-density component. The amount of high-density component in the mixture may range from 5 to 95 percent of the volume of theweighting member 24. - In addition to a high-density component such as tungsten, the multiple component powder or pellet mixture is composed of a binding component such as tin (density of 7.31 g/cm3) or other comparable material. The binding component in the multiple component powder or pellet mixture may range from 4 to 50 percent of the volume of the
weighting member 24. The overall density of theweighting member 24 will range from 11.0 g/cm3 to 17.5 g/cm3, preferably between 12.5 g/cm3 and 15.9 g/cm3, and most preferably 15.4 g/cm3. - Returning to FIG. 10, the powders are thoroughly mixed to disperse the binding component throughout the multiple component powder or pellet mixture. The multiple component powder or pellet mixture may be pre-compacted into slugs for positioning and pressing within the
cavity 25 atblock 206, and as shown in FIG. 13. - Higher densities are achieved by pre-compacting the multiple component powder or pellet mixture prior to placement within the
cavity 25. Atblock 206, the mixture is pressed within thecavity 25 at a pressure between 10,000 pounds per square inch (psi) to 100,000 psi, preferably 20,000 psi to 60,000 psi, and most preferably 50,000 psi. As shown in FIG. 14, apunch 57 is used to exert the pressure on the mixture to compact the mixture to form theweighting member 24. - Once the multiple component powder or pellet mixture is pressed within the
cavity 25, atblock 208 the unfinished golf club head 20 b may optionally be placed within a furnace for heating of the multiple component powder or pellet mixture under standard atmospheric conditions and in air. More precisely, the process of the present invention does not require a vacuum nor does it require an inert or reducing environment as used in the liquid phase sintering processes. In the furnace, the multiple component powder or pellet mixture is heated for 1 to 30 minutes, preferably 2 to 10 minutes, and most preferably 5 minutes with thepunch 57 maintaining a constant pressure on the mixture. The furnace temperature for melting at least one component of the mixture is in the range of 300° F. to 550° F., and is preferably at a temperature of approximately 450° F. The one component is preferably the binding component, and it is heated to its melting temperature to liquefy as shown in FIG. 14. However, those skilled in the art will recognize that the temperature may vary depending on the composition of the multiple component powder or pellet mixture. Preferably the binding component is tin, and the hot pressing occurs at 450° F. to allow the tin to fill in the cavities of the multiple component powder or pellet mixture to reduce porosity and thus increase the density of theweighting member 24. As the tin liquefies, the tungsten (melting temperature of 3400° C.), or other high-density component, remains in a powder form. - At
block 210, the unfinished golf club head with theweighting member 24 therein is finished through milling, grinding, polishing or the like. Thelip 51 is removed at this stage of the process. Those skilled in the art will recognize that the density of theweighting member 24 will change depending on the particular club within a set of irons, or fairway wood or putter. The density is manipulated through modifying the amount of binding component, such as tin, and varying the pressure and temperature as shown in FIGS. 17-19. - FIGS.17-19 illustrate graphs of the compositions of the multiple component powder or pellet mixture, at different compositions and under different pressures and temperatures. The y-axis of each is the Relative Density that is the percent of theoretical or expected density achieved by the measured density. The processing was conducted at standard atmospheric conditions (1 atmosphere) and in air. The theoretical or expected density is the density if mixture was processed in a reducing environment under high pressure. The present invention is able to achieve between 70% to 99% of the theoretical density by using a method that does not require a reducing environment and high pressures.
- FIG. 17 illustrates the Relative Density versus the volume of tin in the mixture of just tin and tungsten (disregarding porosity) that undergoes pressing at 50,000 psi. The highest density, 14.6 g/cm3, is achieved at 22% volume tin whereas the highest relative density (99%), 12.5 g/cm3,is achieved at 50% volume tin.
- FIG. 18 illustrates the Relative Density versus the volume of tin in the mixture of just tin and tungsten (disregarding porosity) that undergoes pressing at 50,000 psi and 100,000 psi. The highest density, 1 5.4 g/cm3, is achieved at 22% volume tin whereas the highest relative density, 99% (13.9 g/cm3), is achieved at 40% volume tin, and at 100,000 psi.
- FIG. 19 illustrates the Relative Density versus the volume of tin in the mixture of just tin and tungsten (disregarding porosity) that undergoes pressing at 50,000 psi and 100,000 psi, and is processed at room temperature and at 450° F. The highest density, 16.6 g/cm3, is achieved at 12% volume tin whereas the highest relative density, 99% (16.4 g/cm3), is achieved at 25% volume tin, at 100,000 psi and at a temperature of 450° F. FIG. 19 illustrates that hot pressing provides a
weighting member 24 that has the highest density and, the highest relative density. - Although the present invention has been described in reference to irons, those skilled in the pertinent art will recognize that the present invention may be utilized with putter heads91 and wood heads 93 as illustrated in FIGS. 15 and 16 respectively.
- From the foregoing it is believed that those skilled in the pertinent art will recognize the meritorious advancement of this invention and will readily understand that while the present invention has been described in association with a preferred embodiment thereof, and other embodiments illustrated in the accompanying drawings, numerous changes, modifications and substitutions of equivalents may be made therein without departing from the spirit and scope of this invention which is intended to be unlimited by the foregoing except as may appear in the following appended claims.
