Music box having dual sets of ornament moving elements
BACKGROUND OF THE INVENTION 
     The present invention relates to a double maneuvered music box having a first moving mechanism driven by a clock-work therefor and a Gear on a pinned barrel thereof to swing or rotate a first set of ornamental moving elements, and a second moving mechanism coupled to the shaft of the pinned barrel to move a variety of second sets of ornamental moving elements. 
     Coventionally, a music box is simply comprised of an apparatus consisted of a pinned barrel and a metal comb, as shown in FIG. 5, that reproduces music mechanically when activated by a clockwork. In order to attract people, a rotary ornament may be used and mounted on a music box. The rotary ornament is rotated when the pinned barrel is turned round and round by the clockwork. Because the rotary ornament can only make a rotary motion when the pinned barrel is rotated, little variation is produced to attract consumers. 
     SUMMARY OF THE INVENTION 
     The present invention has been accomplished under the aforesaid circumstances. It is therefore the object of the present invention to provide a music box which drives a variety of ornaments to move in different directions as the music box is activated. It is another object of the present invention to provide a music box having a first moving mechanism driven by the clock-work and a gear on the pinned barrel to swing or rotate a first set of ornamental moving elements. It is still another object of the present invention to provide a music box having a second moving mechanism driven by the shaft of the pinned barrel to swing, rock, reciprocate, oscillate, push and pull, or rotate a second set of ornamental moving elements.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to FIGS. 1 and 1A, the double maneuvered music box 1 comprises a rotary table 10 coupled to the shaft of the clock-work (not shown) thereof at the top, a first bracket 111 formed on a mount 11 at the top above the pinned barrel 13 and having a key hole 112, which receives the shaft 121 of the transmission gear 12 of a first moving mechanism. The transmission gear 12 is engaged with a gear 131 coupled to the pinned barrel 13 at one end. A swivel plate 115 is mounted on the shaft 121 at the top horizontally, having an upright pin 1151 inserted into an elongated slot 118 on a swinging plate 117, which is mounted on a shaft 116 fastened to the mount 11 at the top. As the pinned barrel 13 is rotated by the clock-work, the swivel plate 115 is turned round and round by the shaft 121 of the transmission gear 12, and therefore the swinging plate 117 is driven by the upright pin of the swivel plate 115 to swing horizontally within 120° angle. The swinging angle of the swinging plate 117 is determined according to the length of the elongated slot 118. A cam 14 is coupled to the pinned barrel 13 at an opposite end and rotated to move an ornament (not shown) above. The mount 11 further comprises a second bracket 113 with axle holes 114 for mounting a curved actuating rod, (not shown). 
     Referring to FIGS. 2 and 2A, a gear 151 has a gear shaft 152 coupled to the shaft 121 of the transmission gear 12 at the top. A rotary table 15 is mounted on She shaft 116, having a pinion (not shown meshed with the gear 151. Therefore, the rotary table 15 is turned round and round by the gear 151 as the pinned barrel 13 is rotated by the clock-work. 
     Referring to FIG. 3, the second moving mechanism is made in the form of a swinging device comprised of a movable frame 17 pivoted to a bottom plate 173 fastened to the casing of the music box 1 and guided by a projecting rod 141 on the cam 14. The projecting rod 141 inserts in a sliding groove 172 on a horizontal extension plate 171 of the movable frame 17. As the pinned barrel 13 is turned round and round, the movable frame 17 is driven by the projecting rod 141 to oscillate back and forth alternatively, and therefore the ornament (not shown) on the movable frame 17 is synchronously moved. 
     Referring to FIGS. 4 and 4A, the second moving mechanism is a reciprocating device which comprises an angle frame 24 fastened to the casing of the music box at one side and having through holes 242 aligned on two horizontal extension boards 241 thereof, the cam 246 equivalent to 14 in FIG. 1, coupled to the shaft of the pinned barrel 13, a horizontal stop plate 243 fastened to the angle frame 24 by a hook 244 thereof and disposed between the cam 246 and the lower horizontal extension board 241, and a reciprocating rod 245 inserted through the through holes 242 on the horizontal extension boards 241 and fixed to the stop plate 243. Turning on the pinned barrel 13 causes the cam 246 to pushes the stop plate 243 up and down vertically and alternatively, and therefore the ornament mounted on the reciprocating rod 245 is reciprocated vertically.
