Int. Cl. Gd 3/14 US. Cl. 84--312 10 Claims ABSTRACT OF THE DISCLOSURE The present invention relates to a tremolo device having handle or lever that is operated by the guitar player so that it can be raised or lowered in a vertical plane as well The present invention is an improvement over my US.

Patent 3,248,991, granted on May 3, 1966.

In the above mentioned patent a tremolo device is provided which has a member having cradle means and a. separate floating bridge element or member, one for each string, for connecting the strings of the instrument thereto, and this cradle means is so arranged as to have limited pivotal movement, so that the tension applied to the strings of the instrument can be readily varied to produce a tremolo effect. 1

This above mentioned patent further provides a tremolo device with a cradle member which carries a plurality of strings provided with means for independently adjusting each string eccentrically with respect to. the pivotal movement of the cradle member, so that the throw of each string with respect to the pivotal axis of the cradle member is independent of the throw of the other strings "therefrom. This tremolo device is further provided with an operating handle so as to pivot the cradle member and to produce the tremolo eifect.

ber, and the means for independently adjusting each string, and with the handle member, the present invention furtherprovides means for moving the handle to a position in which the instrument mayhavea flat tone condition. In the present invention .this handle may be disposed on a stop member or a pin member so thatithe handle is maintained in the flat tone position without the player having to constantly maintain his hand on the handle and hold it in the flat tone condition. I

It is another object of the present invention to provide a handle means for a tremolo device in which the handle means can be swung to another position, opposite the position which produces'a flat tone eifect, and in, which position the handle may be held by another stop means so 55 .;tr'unnion or upstanding or vertical members 38afiixed to 3,466,962 Patented Sept. 16, 1969 ice - device shown in FIGURE 1 and with the handle means of the present invention embodied therein.

FIGURE 3 is a view similar to FIGURE 2, except that it shows the handle disposed in a fixed or stop position with the handle positioned to emit a flat tone condition, as distinguished from the general neutral position of the strings on the instrument;

FIGURE 4 is a side view partly in section taken along the line 44 of FIGURE 2 illustrating the handle disposed in its stop or fixed position wherein the strings emit a sharp tone;

FIGURE 5 is a view taken along the line 55 of FIG- URE 4 also illustrating the handle in its fixed or stop position wherein the instrument emits sharp tone as distinguished from the usual lower tones of the neutral position of the handle;

FIGURE 6 is a view taken along the line 66 of FIG- URE 3 illustrating the handle of the instrument disposed in a fixed position on its cam member wherein flat tone are emitted from the instrument;

FIGURE 7 is a view taken along the line 7-7 of FIG- URE 6 also illustrating the handle in its flat tone position;

FIGURE 8 is a fragmentary detail view of the top end of the handle illustrating the very tip thereof; and

FIGURE 9 is also a fragmentary detail view similar to FIGURE 8, except that it shows the underside of the same end or tip of the handle.

Referring to the drawings the reference numeral 10 generally designates the body of a guitar having a neck 12 terminating in a head, not shown. Strings 14 connected to the tremolo device 16 are provided which strings extend over separate and individual floating bridge members or elements 18.

The tremolo device 16 is provided with a flat plate member 20 which may be secured by screws to the top of the guitar sound box.

plate 28. This member 22 is also provided with a flat transversely extending upper horizontal plate 30 extending between the sides 24 and 26. The strings 14 are connected to a connector element by any suitable means. The connector elements 32 are in turn connected to a connector block and the element 32 and the connector block are journaled on externally threaded members 34 similar to the members described in my Patent 3,248,991. so that the connector elements and the block may be. moved upwardly and downwardly relative to the U-shaped a member and the horizontal plates 28 and 30 by turning the threaded members 34.

The 'vertical side walls 24 and 26 of.the U-shaped member are pivotally journaled on horizontal axis members or pins 36 which are provided in laterally spaced opposite sides of plate 20. It will be noted that the pins 36 are disposed adjacent the right end of the upstanding members 38 so that the U-shaped member 22 and all of the .members afiixed thereto can be rotated or pivoted ,about a transversely extending horizontal axis extending between the members 38.

The U-shaped member 22 is normally maintained in its neutral position or in its ordinary playing position when it is not desired to produce a tremolo etfect by a plate member 40. The plate member 40 is disposed on one side of the U-shaped member 22 and has a lip 42 which overlaps a corresponding lip extending outwardly from the U-shaped member 22 adjacent its lower horizontal plate 28. The lip 42 engages the corresponding lip on the U-shaped member 22 and a bolt member 44 having a coil spring 46 thereon biases the plate 40 in a downward position and the lip 42 so as to maintain the lip 42 in a downward position to hold the U-shaped memher in its normal playing position.

An elongated operating handle 48 is pivotally connected by a bolt member 50 to one side of the U-shaped member 22. The handle 48 is swingable in a clockwise or a counter-clockwise direction about the axis of the bolt member 50 and is further provided with a spacer washer 52 thereon, as best seen in FIGURE 6 so that the handle may be raised or lowered or swung in an upwardly or downwardly direction. The front end or the tip 54 of the handle 48 as best seen in FIGURES 8 and 9 is provided with a cut away portion or recess 56 with a slight taper as indicated at 58 or a bevel to guide the handle as hereinafter described. The bevel 58 is provided on the top side of the tip 54 of the handle while a triangular shaped cut out or notch 60 is provided on the bottom side 62 of the handle adjacent the tip 54. l

A stop member 64 which is the stop member for the sharp tone condition of the instrument is provided adjacent one side of the upstanding member 38. The stop member 64 is substantially L shaped in side elevation and may be secured to member 38 by a bolt 66 or other similar means. The sharp stop member 64 is provided with a horizontally extending slot 68 therein, as best seen in FIGURE 7 which is cut on an incline or bevel and disposed adjacent the inner side of the stop member 64 to receive the tip 54 of the handle and so as to enable the corresponding taper or bevel 58 of the tip 54 to easily slide into the slot 68.

During the normal playing operation of the instrument, the handle extends in a direction parallel to the neck 12 of the instrument. When it is desired to place the instrument in a sharp condition so that the tone is of a higher pitch, the handle 68 is swung in a clockwise direction from the position facing the rear of the instrument to the position shown in FIGURE 2. The handle is also raised so that the tip 54 will slide into the slot 68 as best seen in FIGURES 2, 4 and so that it will be permanently held therein until released by the operator. Thus the player of the instrument no longer has to maintain pressure on the handle and to maintain it in a particular position by hand in order to produce the sharp tone eifect desired.

When it is desired to position the handle of the instrument in a fiat tone position, this is accomplished by setting the handle 48 on a cam member 70 which is a pin member disposed in the lug or upstanding member 38 adjacent the stop member 64. This cam member 70 provides a stop position for the handle when it is to be maintained in its fiat tone position. In order to remove the handle from the position shown in FIGURES 4 and 5 in which it is disposed in its sharp tone condition, to a point or condition where it provides sound of a flat tone nature, the handle 48 is swung from the position illusr; trated in FIGURE 2 to the position shown in FIGURE 3.

Thus the handle is raised and moved in a clockwise,

handle operating means in which the handle operating means is further provided with stop mean positions thereon so as to enable the instrument to emit sounds of a sharp tone or sounds of a fiat tone, as distinguished from the ordinary sounds emitted therefrom and which handle means do not have to be held by the instrument player in this position, but in which the handle can be locked into its desired position without any further effort on the part of the player.
