BACKGROUND OF THE INVENTION  
         [0001]    (a) Field of the Invention  
           [0002]    The present invention relates to a compound putter with variable angles, and more particularly to one that provided with a putter face and a chipper face on the same head, which is pivoted to the shaft with appropriate tightness to change the angle of the head and the shaft depending on the use of a putter or a chipper.  
           [0003]    (b) Description of the Prior Art  
           [0004]    Golf club is usually provided with only one face and each has a dedicated purpose. More than a dozen of clubs have to be stuffed in the golf bag whenever one feels to swing a few holes and that&#39;s not convenient and consuming a lot of strength. Particularly, in a tournament, the number of the clubs is restricted (generally not more than fourteen clubs). Therefore, the player has to make decisions depending on conditions of the course. Slope and topographic factors around the peripheral of the green are liable for drastic changes while the length of the grass on the green varies, making the selection of a chipper and the skill to chip the ball even more crucial. The player usually uses seven iron, eight iron or pitching club to handle the ball falling in the 5-m peripheral of the green since the number of clubs is limited. For a player, amateur or pro, whose skill is not perfect to make such a chip, the limited selection of a proper club will be frustrated with a seven iron, eight iron or pinching wedge.  
         SUMMARY OF THE INVENTION  
         [0005]    The primary purpose of the present invention is to provide a compound putter with variable angles that has a putter face and a chipper face on the same head while both of the head and the shaft are pivoted with a proper tension to allow change the relative angle between the head and shaft for deciding upon which face to be used in handling the ball on the green or on its peripheral. That is, one club is enough to handle without giving upon the chipper for event that the number of clubs is restricted.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0018]    Referring to FIGS. 1 and 2, a first preferred embodiment of the present invention is composed of a shaft ( 1 ), a head ( 20 ), a putter face ( 3 ) and a chipper face ( 4 ). The lower section of the shaft ( 1 ) is pivoted to the head ( 2 ).  
         [0019]    A transversal through hole ( 11 ) is provided at the lower end of the shaft ( 1 ) with two C-shaped elastic washers ( 12 ) and ( 13 ), and a pivot ( 14 ) in the form of a bolt.  
         [0020]    The head ( 2 ) is divided into a left half ( 2 A) and a right half ( 2 B) to facilitate manufacturing process (of course, the head can be integrated in one piece as illustrated in FIG. 7). A ½ recess ( 21 A,  21 B) is each respectively provided inside the left half ( 2 A) and the right half ( 2 B). The recess ( 21  A) has a screw hole ( 211 ) provided in the inner wall with additional two screw holes ( 22 ) and ( 23 ). Another two through holes ( 24 ) and ( 25 ) are provided in the right half ( 2 B) with two bolts ( 26 ) and ( 27 ). The chipper face ( 4 ) is secured to the outer surface of the left half ( 2 A), and the putter face ( 3 ) is secured to the outer surface of the right half ( 2 B).  
         [0021]    As illustrated in FIGS. 2 and 3, both halves ( 2 A) and ( 2 B) of the head ( 2 ) are locked to each other with the bolts ( 26 ) and ( 27 ). Both of the bolts ( 26 ) and ( 27 ) are respectively penetrating the two through holes ( 24 ) and ( 25 ) in the right half ( 2 B) and respectively to both of the screw holes ( 22 ) and ( 23 ) in the left half ( 2 A) thus for both of the halves ( 2 A) and ( 2 B) to form the head ( 2 ). Meanwhile, both of the halves ( 21 A) and ( 21 B) are formed into a complete recess ( 21 ). Both sides of the through hole ( 11 ) at the lower end of the shaft ( 1 ) are respectively lined with the elastic washers ( 12 ) and ( 13 ) before the lower end of the shaft ( 1 ) is placed into the recess ( 21 ), then the pivot ( 14 ) penetrates the through hole ( 212 ) and engaged in the screw hole ( 211 ). The chipper face ( 4 ) is fixed onto the outer surface of the left half ( 2 A) and the putter face ( 3 ) is fixed onto the outer surface of the right half ( 2 B) for the same head ( 2 ) to be provided with two faces, the putter face ( 3 ) and the chipper face ( 4 ), at the same time.  
         [0022]    As illustrated in FIGS. 4, 5 and  6 , though the shaft ( 1 ) is pivoted to the head ( 2 ), a proper tension is provided due to the elastic washers ( 12 ) and ( 13 ) are compacted. Therefore, the relative angle between the shaft ( 1 ) and the head ( 2 ) vanes depending on the force applied, both of the shaft ( 1 ) and the head ( 2 ) maintains in their secured positions under normal conditions to adapt to different conditions of topography on the course. Though only the chipper face ( 4 ) is disclosed as illustrated in FIGS. 5 and 6, the putter face ( 3 ) is also applicable.  
         [0023]    [0023]FIG. 7 shows a second preferred embodiment of the present invention. The head is integrally formed in one piece and provided with the recess ( 21 ), the putter face ( 3 ) and the chipper face ( 4 ).  
         [0024]    A third preferred embodiment of the present invention as illustrated in FIG. 8 is composed of a shaft ( 5 ), a head ( 6 ), a putter face ( 7 ), and a chipper face ( 8 ). The lower section of the shaft ( 5 ) is connected to the head ( 6 ).  
         [0025]    A transversal through hole ( 51 ) adapted with a pivot ( 52 ) in a form of a bolt is provided in the lower end of the shaft ( 5 ).  
         [0026]    The head ( 6 ) is divided into two halves ( 6 A) and ( 6 B). The left half ( 6 A) has a recess ( 61 A) and a screw hole ( 611 ) is provided in the inner side of the recess ( 61  A) and another two screw holes ( 62 ) and ( 63 ) are provided on the outer surface of the left half ( 6 A) leaving the screw hole ( 611 ) in between on the same side. Three through holes ( 64 ), ( 65 ) and ( 66 ) are provided in the sidewall of the right half ( 6 B) adapted with two bolts ( 67 ) and ( 68 ). The chipper face ( 8 ) is provided over the outer surface of the left half ( 6 A) and a putter face ( 7 ), to the right half ( 6 B).  
         [0027]    By respectively inserting the bolts ( 67 ) and ( 68 ) into two through holes ( 64 ) and ( 66 ) and engaging into the two screw holes ( 62 ) and ( 63 ) of the left half ( 6 A), both halves ( 6 A) and ( 6 B) for the head ( 6 ). Then the pivot ( 52 ) enters into the through hole ( 65 ) and engages in the screw hole ( 611 ). Finally the chipper face ( 8 ) is secured to the outer side of the left half ( 6 A) and the putter face ( 7 ), to the right half ( 6 B) to complete the head ( 6 ) provided at the same time with two faces, the chipper face ( 8 ) and the putter face ( 7 ). Furthermore, by having both bolts ( 67 ) and ( 68 ) to press against the left half ( 6 A) and the right half ( 6 B), a proper tension is given to the lower end of the shaft ( 5 ). Consequently, when a proper force is applied by the player, a relative angle between the shaft ( 5 ) and the head ( 6 ) swivels and said relative angle remains fixed in the absence of such force.  
         [0028]    Referring to FIGS. 9, 10,  11  and  12  for a structure and operation of a telescopic shaft of the present invention. As all the preferred embodiments disclosed herein share the same telescopic shaft of the present invention, only the shaft ( 1 ) taken from the first preferred embodiment is described. (The shaft ( 5 ) in the third preferred embodiment has the same telescopic structure as that for the first and the second preferred embodiments, thus will not be described). A telescopic shaft ( 9 ) is inserted into the shaft ( 1 ) from its top where then fixed with a hollow retainer ring ( 15 ). The inner diameter of the retainer ring ( 15 ) is equal to the outer diameter of the telescopic shaft ( 9 ). A deflection shaft ( 91 ) extending from the lower end of the telescopic shaft ( 9 ) has on its side abutted to the lower end of the telescopic shaft ( 9 ) provided with an ear ( 92 ). A deflection holder ( 93 ) having a deflective hole ( 931 ) to accommodate the penetration by the deflection shaft ( 91 ) and a wall ( 932 ) is provided to the deflection holder ( 93 ) at where in relation to the ear ( 92 ). The terminal of the deflection shaft ( 91 ) is secured with a retainer ( 94 ) after penetrating through the deflective hole ( 932 ). The retainer ( 94 ) is provided with a recess ( 941 ) to be inserted by and to secure (or otherwise by welding or adhesion) the deflection shaft ( 91 ) with the outer diameter of the retainer ( 94 ) slightly smaller than the inner diameter of the shaft ( 1 ) but larger than the inner diameter of the retainer ring ( 15 ). As a result, the telescopic shaft ( 9 ) moves inside the shaft ( 1 ) without escaping from the shaft ( 1 ). As illustrated in FIG. 12 for the positioning of the telescopic shaft ( 9 ), when the telescopic shaft ( 9 ) is turned, the ear ( 92 ) is pushed to hold against the wall ( 932 ), thus to cause the deflection holder ( 93 ) to deflect with the deflection shaft ( 91 ) to such extent that the deflection holder ( 93 ) holds against the inner wall of the shaft ( 1 ) in position for use. On the contrary, the telescopic shaft ( 9 ) completes its cycle in the shaft ( 9 ) by inversely turning the telescopic shaft ( 9 ) for the ear ( 92 ) to turn for a certain degree to push the wall ( 932 ) and the deflection holder ( 93 ) deflects to its initial position.  
         [0029]    As disclosed above, the present invention offers golf players to carry less clubs, better handle the ball on and to the green depending on the topographic conditions, and less efforts in carrying the clubs.
