Transmission mechanism for music box ornament

Abstract

A transmission mechanism for music box ornament, including a rotary wheel rotated by the eproducer of a conventional wind-up music box mechanism and having an eccentric rod, a locating block fixedly mounted within a base plate within which the wind-up music box mechanism is mounted, a follower plate supported on the eccentric rod and vertically 10 reciprocated by it along a downward rod on the locating block, and a tappet rod inserted through a hole on the locating block and driven by the follower plate to reciprocate an ornament.

I claim: 
     
       1. A transmission mechanism for music box ornament, comprising: a rotary wheel rotated by a reproducer of a wind-up music box mechanism, said rotary wheel having an eccentric rod;   a locating block fixedly mounted within a base plate within which said wind-up music box mechanism is mounted, said locating block comprising a channeled vertical wall and a flat horizontal wall perpendicularly extended from top of said channeled vertical wall, said flat horizontal wall having a downward guide rod at one end of said flat horizontal wall and a through hole at an opposite end;   a follower plate supported on said eccentric rod and moved by it along said channeled vertical wall and said downward guide rod of said locating block, said follower plate having a mounting hole at one end aligned with said through hole of said flat horizontal wall of said locating block, and a guide hole at an opposite end, which loosely receives the downward guide rod of said locating block;   a copper sleeve fixedly mounted within said through hole of said flat horizontal wall of said locating block; and   a tappet rod inserted through said copper sleeve and reciprocated by said eccentric rod through said follower plate, said tappet rod having a bottom end fixedly fastened to the mounting hole of said follower plate, and a top end coupled with an ornament. .[.2. The transmission mechanism of claim 1 wherein said base plate is supported on a rocker, having an upright guide block at one end, a through hole adjacent to said upright guide block, a T-rod inserted through said through hole and stopped beneath said eccentric rod of said rotary wheel, and a spring mounted around said T-rod to impart upward force to said T-rod against said eccentric rod of said rotary wheel, said T-rod being alternatively moved up and down by said eccentric rod of said rotary wheel and said spring to force said rocker moved forwards and backwards alternatively when said wind-up music box mechanism is operated..]..Iadd.3. The transmission mechanism of claim 1 further comprising a seesaw coupled to a driving mechanism of said wind-up music box mechanism and turned back and forth to impart alternating vertical movement of two ornaments. .Iaddend..Iadd.4. A transmission mechanism for music box ornament, comprising:   a rotary wheel rotated by a reproducer of a conventional wind-up music box mechanism and having an eccentric rod;   a tappet rod having a bottom end fixedly fastened on said music box and a top end coupled with an ornament;   a rocker;   a supporting plate for mounting a base of said wind-up music box mechanism thereon, which is supported on said rocker and has an upright guide block at one end, a through hole adjacent to said upright guide block, a T-rod inserted through said through hole and stopped beneath said eccentric rod of said rotary wheel, and a spring mounted around said T-rod to impart upward force to said T-rod against said eccentric rod of said rotary wheel, said T-rod being alternatively moved up and down by said eccentric rod of said rotary wheel and said spring to force said rocker moved forwards and backwards alternatively when said wind-up music box mechanism   
     
     
        is operated. .Iaddend..Iadd.5.  The transmission mechanism of claim 4 wherein said support plate has a plurality of lugs at two opposite sides respectively fastened to two opposite sides of said rocker. .Iaddend..Iadd.6. The transmission mechanism of claim 4 wherein said rocker has a hole for passing said T-rod therethrough. .Iaddend..Iadd.7. A transmission mechanism for a music box having an ornament mounted thereon, comprising: a rocker;   a driving device having a rotary wheel with an eccentric rod and disposed in said music box; and   a support connecting said music box with said rocker and having a following piece to be inserted through a hole of said rocker and stopped beneath said eccentric rod, and a resilient element for urging said following piece against said eccentric rod, wherein said following piece is alternately moved up and down by said eccentric rod and said resilient element to force said rocker moved forwards and backwards alternately when said rotary wheel is rotated. .Iaddend..Iadd.8. The transmission mechanism of claim 7 wherein said ornament is connected to said music box through a tappet. .Iaddend..Iadd.9. The transmission mechanism of claim 7 wherein said following piece is a T-rod. .Iaddend..Iadd.10. The transmission mechanism of claim 7 wherein said resilient element is a spring. .Iaddend..Iadd.11. The transmission mechanism of claim 7 wherein said support has a plurality of lugs at two opposite sides respectively   
     
     
        fastened to two opposite sides of said rocker. .Iaddend..Iadd.12.  The transmission mechanism of claim 7 wherein said support has a through hole to enable one end of said following piece to pass therethrough. .Iaddend..Iadd.13. The transmission mechanism of claim 12 wherein said support further includes an upright guide block adjacent to said through hole for guiding said following piece to vertically move up and down. .Iaddend.
