       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a spring operated record player organ, and more particularly, to a record player organ which is driven by the restoring force of a comb spring leaf.  
         [0003]     2. Description of the Prior Art  
         [0004]     Referring to  FIG. 4 , it is a schematic view of a conventional motor operated record player organ. As shown in  FIG. 1 , a comb spring leaf  71  is provided on a base apparatus  7 , a set pin  72  and a driving motor  73  are respectively installed on each side of the comb spring leaf  71 . The driving motor  73  is screw combined with a double herical gear  74 , while the double herical gear  74  is screw combined with a ratchet wheel  75 . Several pawl wheels  751  and a player driving gears  752  are coaxially installed on the shaft of the ratchet wheel  75  in order. The player driving gear  752  is for driving a record player  77 .  
         [0005]     The base apparatus  7  which being installed at one side of the motor  73  has a fixed axle  76 . A hasp  761  is provided at the end terminal of the fixed axle  76  so as to fasten the fixed axle  76  to the set pin  72 .  
         [0006]     When it is intended to play music, at first settle the player  77  on the set pin  72 , and engage the hasp  761  with the set pin  72  such that the player  77  is set between the ratchet wheel  75  and the fixed axle  76 . Next, energize the motor  73  from the power source so as to drive the double herical gear  75  and the player driving gear  752  which in turn drives the player  77  to rotate, and by mutual action between the apertures formed on the player  77  and the driving gear  751  so that the comb spring leaf  71  is actuated to play a rhythmical music.  
         [0007]     However, the conventional spring operated record player organ constructed as such has the following shortcomings, namely:  
         [0008]     1. A power supply is necessary to operate this apparatus that causes it unable to play where there is no available power source.  
         [0009]     2. A electric wiring is necessary in the apparatus that makes its construction complicated and frangible so that a very careful attention for operation and transportation is required.  
         [0010]     For these shortcomings noticeable on the prior art, an improvement is seriously required.  
         [0011]     The inventor has dedicated great efforts for years to studying and improving these shortcomings and come up with a novel spring operated record player organ as provided in this invention to eliminate the shortcomings mentioned above.  
       SUMMARY OF THE INVENTION  
       [0012]     It is an object of the present invention to provide a spring operated record player organ which is operated with a spring wound around a rotating shaft so as to drive the player by restoring force of the spring instead of an extra power supply.  
         [0013]     Another object of the present invention is to provide a spring operated record player organ whose rotating shaft is constructed in the aspect that it is erected to pierce through the spring cover and the base apparatus. A rotary switch to twist the coil spring is provided on the top end of the rotating shaft so as to wind up the coil spring before rotating the player.  
         [0014]     Another object of the present invention is to provide a spring operated record player organ capable of operating only by the restoring force of the spring so that the organ is usable anywhere and anytime without seeking for another power supply.  
         [0015]     Another object of the present invention is to provide a spring operated record player organ which does not have to be turned up side down for operation by providing a rotary switch on the spring cover to twist the spring, and the assembly process is facilitated by placing the base apparatus horizontally on a bottom plate when assembling the organ in the mechanism.  
         [0016]     To achieve these and other objects mentioned above, the present invention includes a base apparatus, a driving unit, a gear set, a fixed axle unit, a record player, and a rotation speed governor.  
         [0017]     The base apparatus is composed of a comb spring leaf, a ratchet wheel shaft on which being provided with equal numbers of actuating ratchet wheels as that of the teeth of the comb spring leaf, and a player driving gear. All of the actuating ratchet wheels and the player driving gear are coaxially coupled to the ratchet wheel shaft. The comb spring leaf and the ratchet wheel shaft are mutually coupled in a state such that the actuating ratchet wheels can tap the teeth of the comb spring leaf to output various octavant musical sound.  
         [0018]     The driving unit has a spring cover fitted at one side of the base apparatus, and the spring cover has a rotating shaft piercing through its top surface and a first crown gear is enclosed underneath by the spring cover. A rotary switch is provided at the other side where the rotating shaft is coupled with the first crown gear. A coil spring is wound around the rotating shaft. The rotary switch is to wind up the coil spring. When the rotary switch is released, the restoring force of the coil spring drives the rotating shaft to rotate which in turn drives the first crown gear.  
         [0019]     The gear set is equipped between the comb spring leaf and the driving unit. The gear set is composed of a second crown gear, a first step spur gear, a second step spur gear, a double herical gear, and a speed reducer. As the first and second crown gears are in mesh with each other, the rotation of the first crown gear puts the gear set in motion which in turn drives the ratchet wheel shaft thereby all the ratchet wheels are actuated to tap the comb spring leaf.  
         [0020]     The fixed axle unit is provided with a set pin and a fixed axle. The set pin is located in the base apparatus at the position distantly apart from the driving unit and extended in the direction apart from the base apparatus. One end of the set pin is pivoted to the spring cover, while the other end thereof is provided with a hasp to fasten the fixed axle in parallel with the ratchet wheel shaft. Besides, several rotating wheels are fitted with the fixed axle coaxially in series.  
         [0021]     A record player with a drilled hole formed at its center allows the set pin to pierce through. The record player is provided with a plurality of tapping apertures distributed at random on its surface, and a plurality of driving holes are formed around the record player at the positions near its fringe such that when the record player is driven to rotate by the player driving gear, the driving holes formed around the fringe of the record player will never fail to mesh the player driving gear since the record player is properly pressed by the rotating wheels of the fixed axle.  
         [0022]     The rotation speed governor is provided beneath the bottom apparatus and the driving unit. It is composed of a speed stabilizing cam and a speed stabilizing wheel. The speed stabilizing cam is mated with the rotating shaft at the end distantly apart from the rotary switch for the coil spring, on the other hand the speed stabilizing wheel is in mesh with the speed stabilizing cam. With the aid of the rotation speed governor, the operation of the mechanism is difined to take place during the time interval the restoring force of the coil spring is at the best stable state thereby the music can be played pleasantly to the ear with stabilized rotating speed of the mechanism.

         [0030]     The driving unit  2  has as spring cover  21  fitted at one side of the base apparatus  1 , and the spring cover  21  has a rotating shaft  211  piercing through its top surface and a first crown gear  212  is enclosed underneath by the spring cover  21 . A rotary switch  22  is provided at the other side where the rotating shaft  211  is coupled with the first crown gear  212 . A coil spring  23  is wound around the rotating shaft  211 , while the rotary switch  22  is to wind up the coil spring  23 . When the wound coil spring  23  is released, the restoring force of the coil spring  23  drives the rotating shaft  211  which in turn drives the first crown gear  212 .  
         [0031]     The gear set  3  is equipped between the comb spring leaf  11  and the driving unit  2 . The gear set  3  is composed of a second crown gear  31 , a first step spur gear  32 , a second step spur gear  33 , a double herical gear  34 , and a speed reducer  35 . As the first and second crown gears  212  and  31  are in mesh with each other, the rotation of the first crown gear  212  puts all component parts in cluded in the gear set  3  (second crown gear  31 , first step spur gear  32 , second step spur gear  33 , double herical gear  34 , speed reducer  35 ) in motion. The second step spur gear  33  which being mated with the second crown gear  31  then in turn drives the ratchet wheel shaft  12  thereby all the ratchet wheels  121  are actuated to tap the comb spring leaf with a proper rotating speed under control of the speed reducer  35 .  
         [0032]     The fixed axle unit  4  is provided with a set pin  41  and a fixed axle  42 . The set pin  41  is located in the base apparatus  1  at the position distantly apart from the driving unit  2  and extended towards the direction apart from the base apparatus  1 . One end of the set pin  41  is pivoted to the spring cover  21 , while the other end thereof is provided with a hasp  421  to be inlaid into a circular slot  411  formed around the upper portion of the set pin  41  so as to fasten the fixed axle  4  in parallel to the ratchet wheel shaft  12 . Besides, several rotating wheels  422  are fitted with the fixed axle  42  coaxially in series.  
         [0033]     A record player  5  with a drilled hole  51  formed at its center to allow piercing the set pin  41  through is provided with a plurality of tapping apertures  52  distributed at random on its surface, and a plurality of driving holes  53  are formed around the record player  5  at the position near its fringe thereof such that when the record player  5  is driven to rotate by the player driving gear  122 , the driving holes  53  are able to mate the player driving gear  122  surely since the record player  5  is properly pressed by the rotating wheels  422  of the fixed axle  42 .  
         [0034]     The rotation speed governor  6  is provided beneath the base apparatus  1  and the driving unit  2 . As shown in  FIG. 3 , it is composed of a speed stabilizing cam  61  and a speed stabilizing wheel  62 . The cam  61  is mated with the rotating shaft  211  at the end distantly apart from the rotary switch  22  for the coil spring  23 , on the other hand, the wheel  62  is in mesh with the cam  61 . With the aid of the rotation speed governor  6 , the operation of the mechanism is difined to take place during the time interval the restoring force of the coil spring  23  is at its best stable condition thereby the music can be played pleasantly to the ear with a stabilized rotating speed of the record player  5 .  
         [0035]     The speed stabilizing wheel  62  of the rotation speed governor has a plurality of equally sized, equally spaced, similarly shaped teeth and one differently shaped tooth, and the number of similarly shaped teeth is in match with the length of the coil spring and the stable restoring force acting time interval of the coil spring.  
         [0036]     To operate the mechanism of the present invention, put the mechanism on a platform or a desk; then release the hasp  421  from the circular slot  411  formed around the set pin  41 ; then insert the drilled hole  51  of the record player  5  into the set pin  41  and again inlay the hasp  421  into the circular slot  411  so as to mate the player driving gears  122  on the ratchet wheel shaft  12  with the driving holes  53  formed along the fringe of the record player  5 , and with the aid of the rotating wheels  422  of the fixed axle  42  to properly press onto the record player  5  so that the driving holes  53  keep in mesh with the gears  122  without the worry of disengagement; then rotate the rotary switch  22  to twist the coil spring  23  winding around the rotating shaft  211  thereby storing the energy in the twisted coil spring  23 .  
         [0037]     After releasing the rotary switch  22 , the mutually mated speed stabilizing wheel  62  and cam  61  begin to rotate together until reaching the last tooth the coil spring  23  is able to drive the first and second crown gear  212  and  31  depending on its own restoring force. The gear set  3  is in turn actuated to rotate and drive the player driving gear  122  so that the record player  5  is driven to rotate. As the record player  5  rotates, the combined action of the driving holes  53  and the actuating wheels  121  makes the latter to tap the comb spring leaf  11  to output a pleasant rhythmical music. For stabilizing the operation of the mechanism of the present invention, action of the speed stabilizing wheel  62  and cam  61  must well cooperate to define the operation of the mechanism to take place during the time interval the restoring force of the coil spring  23  is at its best stable condition thereby the music can be played pleasantly to the ear.  
         [0038]     In addition, the position of the actuating holes  53  on the player  5  can be varied in accordance with the different melody so that its serves the individual user a wide selection.  
         [0039]     It emerges from the above description that the spring operated record player organ has several noteworthy advantages compared with that made of any conventional technique, namely:  
         [0040]     1. The mechanism is operated by a manually twisted coil spring associated with several gear combination so that any other extra power supply such as the utility power or the battery unit is not necessary.  
         [0041]     2. The rotary switch for twisting the coil spring is provided on top of the rotating shaft so it is convenient to wind up the coil spring without tampering with the base apparatus before rotating the record player.  
         [0042]     3. The operation of the mechanism is defined to take place during the time interval the restoring force of the coil spring is at its best stable condition thereby the music can be played pleasantly to the ear.  
         [0043]     Many changes and modifications in the above described embodiment of the invention can, of course, be carried out without departing form the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
