| Abstract: |
The tremolo apparatus of the present invention includes a tremolo means (13) with a tremolo bar (19) and a base flange (23) which extends into a cavity (21) in the guitar (11). When the tremolo means is operated conventionally, springs (25) return the tremolo means (13) to an original position against a stop (37) located in the cavity (21). Stop (37) is mounted for movement on rods (42 and 44) against the action of springs (47 and 49). When the tremolo bar (19) is moved toward the body of the instrument, such as a guitar, the tremolo means (13) moves in a first direction wherein the base flange (23) moves away from stop (37), while when the tremolo bar (19) is moved away from the body of the guitar, the tremolo means moves in a second direction wherein the base flange (23) moves stop (37) against the action of springs (47 and 49). Springs (47 and 49) return stop (37) and the base flange (23) and hence the tremolo means (13) to their original position when the tremolo bar is released.

I claim:
1. A tremolo apparatus for a stringed musical instrument comprising:
- tremolo means to which a plurality of strings of a musical instrument are adapted to be secured for movement therewith;
- mounting means for mounting said tremolo means on a stringed musical instrument for movement from a first position to a second position to simultaneously decrease the tension of said plurality of strings, and for movement from said first position to a third position to simultaneously increase the tension of said plurality of strings;
- tremolo moving means for moving said tremolo means from said first position toward said second position and for moving said tremolo means from said first position toward said third position;
- a moveable stop member engageable with said tremolo means, said stop member being moveable between a first member position and a second member position displaced from said first member position, and said moveable stop member being arranged with respect to and cooperating with said tremolo means such that (i) said tremolo means is in said first position when said stop member is in said first member position and said tremolo means is in engagement therewith, (ii) said tremolo means is out of engagement with said stop member when said tremolo means is in one of said second and third positions, and (iii) said tremolo means is in engagement with said stop member and said stop member is in said second member position when said tremolo means is in the other of said second and third positions; and
- tremolo return means comprising first spring means urging said moveable stop member toward said first member position, and second spring means urging said tremolo means toward said stop member, whereby said tremolo means is normally positioned at said first position and is urged by said tremolo return means to return to said first position upon release of said tremolo moving means after having been moved to either of said second or third positions.
