Detailed Description: 

DESCRIPTION OF THE PREFERRED EMBODIMENT 
&lsqb;0015&rsqb; Referring to FIG. 1, a golf putter head is indicated generally by the reference numeral 10. The putter head 10, as shown in the exploded view of FIG. 2, is formed of multiple components including a face member 12, a hosel 14, a back body 16 and a membrane 18. These components are held together by a pair of screws 20. The hosel 14 has a boss 15 for receiving one end of a golf shaft (not shown). 
&lsqb;0016&rsqb; The face member 12 has a sole 22, a toe end 24, a heel end 26, a front surface 28 arranged for striking a golf ball (not shown), a top ledge 30 and a rear surface 32. The top ledge 30 is disposed between the front and rear surfaces 28, 32. A cavity 34 is formed in the rear surface 32 with the cavity 34 having a recessed bottom surface 36 circumscribed by a rim surface 38. An upwardly opening socket 40 is formed in the top ledge 30 of the face member 12 for receiving a depending extension 42 of the hosel 14 as shown in FIG. 4. The face member 12 and the hosel 14 are preferably formed of suitable metal such as stainless steel. When both the face member 12 and the hosel 14 are formed of metal, a sintering process may be used to secure the hosel 14 to the face member 12. Alternatively, the hosel 14 may be formed of a suitable synthetic resin and secured to the face member 12 by using an adhesive such as epoxy. It will be apparent that by fabricating the face member 12 and the hosel 14 as separate components and securing them together in the manner indicated, face members having different configurations may be provided. The face member 12 may be selected from a plurality of differently configured face members, and the hosel 14 may be selected from a plurality of differently configured hosels. 
&lsqb;0017&rsqb; Alternatively, the face member 12 and the hosel 14 are integrally connected to each other to form a face member and hosel combination. FIGS. 8-11 show a plurality of differently configured face member and hosel combinations 13a, 13b, 13c and 13d from which to select. These face member and hosel combinations 13a-13d include respective face members 12a-12d and hosels 14a-14d. 
&lsqb;0018&rsqb; The back body 16 has a sole 44, a toe end 46, a heel end 48 and a mating section or projection 50 which is shown best in FIGS. 2 and 5. The mating section 50 of the back body 16 is separated along its lower edge 51 from the sole 44 by a lip 52 which extends between front end portions 54 and 56 of the back body 16. The mating section 50 has an elongated upper edge 58 opposite the lower edge 51. It is contemplated that a plurality of differently configured back bodies will be fabricated to provide a selection of back bodies having various weights and shapes. The back body 16 may be formed of any suitable material such as metal or synthetic resin. The mating section 50 of the back body 16 has a shape that matches the shape of the recessed bottom surface 36 of the face member cavity 34 to provide a proper fit when the face member 12 and the back body 16 are secured together as described below. 
&lsqb;0019&rsqb; A plurality of differently configured back bodies 16a, 16b and 16c from which to select are shown in FIGS. 12-14. It will be understood that any of the face member and hosel combinations 13a, 13b, 13c, 13d may be secured to any of the back bodies 16a, 16b, 16c thereby providing twelve different putter head configurations. The back bodies 16a, 16b, 16c may be formed of any suitable material such as metal or synthetic resin. Preferably, the back bodies 16a, 16b, 16c are formed of polymer containing tungsten powder. The polymer may contain varying amounts of tungsten powder which will provide back bodies 16a, 16b, 16c of different weights. Each of the back bodies 16a, 16b, 16c may be provided in three different weights, i.e. light weight, medium weight and heavy weight. When the twelve different putter head configurations, mentioned above, are combined with the three different weights of back bodies, thirty-six different putter heads may be assembled. 
&lsqb;0020&rsqb; As seen in FIG. 2, the face member 12 is provided with a spaced apart pair of counterbores 60 and 62 formed proximate the toe and heel ends 24 and 26, respectively, with the counterbores 60, 62 extending from the front surface 28 through to the back surface 32. The back body 16 is formed with a spaced apart pair of threaded bores 64 and 66 (FIG. 5) adjacent the toe and heel ends 46 and 48, respectively, which are disposed to axially align with the counterbores 60, 62 in the face member 12 when the back body 16 is secured to the face member 12 by the screws 20. The mating section 50 of the back body 16 is disposed within the cavity 34 of the face member 12 with the upper edge 58 of the mating section 50 lying beneath the top ledge 30 of the face member 12 as shown in FIGS. 3 and 4. Therefore, a parting line 11 (FIG. 1) between the face member 12 and the back body 16 is concealed by the top ledge 30 and is not visible from directly above the putter head 10 such as when a golfer is making a putting stroke with a putter incorporating the putter head 10. 
&lsqb;0021&rsqb; Referring to FIG. 2, it will be understood that the membrane 18 may be formed with a shape that matches the shape of the cavity 34 in the face member 12 and the shape of the mating section 50 of the back body 16. As seen in FIGS. 3 and 4, when the putter head 10 is assembled, the membrane 18 is positioned between the recessed bottom surface 36 of the cavity 34 in the face member 12 and the mating section 50 of the back body 16. The membrane 18 is preferably made of a thin layer of elastomeric material such as foam tape which has adhesive on both sides for bonding the face member 12 to the back body 16. It will be understood that the membrane 18 may be die cut into a desired shape. Although the putter head 10 may be assembled without utilizing the membrane 18, it is preferred that the membrane 18 be used because it will absorb vibration and enhance the sound made when a golf ball is struck on the front surface 28 of the face member 12. 
&lsqb;0022&rsqb; Another golf putter head is identified in FIGS. 6 and 7 by the reference numeral 68. The putter head 68 includes a face member 70 and a hosel 72 joined together in the manner described with respect to the face member 12 and the hosel 14 of the putter head 10. The face member 70 has a top ledge 71 that is similar to the top ledge 30 of the face member 12, and the hosel 72 includes a depending extension 73 that is similar to the depending extension 42 of the hosel 14. The putter head 68 also includes a back body 74 with a mating section 75 that is similar to the mating section 50 of the back body 16. A pair of screws 76 (only one of which is shown) are used to secure the face member 70 and the back body 74 together. The screws 76 pass through holes 78 (only one of which is shown) formed in the back body 74 into threaded bores 80 (only one of which is shown) provided in the face member 70. The holes 78 are disposed generally normally with respect to the mating section 75. Plates 82 may be inserted into recesses 84 formed in the back body 74 to conceal the screws 76. The plates 82 may be made of metal or plastic and secured in place with a suitable adhesive. When the putter head 68 is assembled, the mating section 75 of the back body 74 has an upper edge 77 that lies beneath the top ledge 71 of the face member 68 so that a parting line 69 between the face member 70 and the back body 74 is concealed by the top ledge 71.
