Appl. No.:

11/359082

Inventors:

Curtis Robert LeBlanc - Thibodaux LA, US

International Classification:

G10D 3/04

US Classification:

84298

Abstract:

The present invention relates to a machine for changing the key of a stringed musical instrument. The machine includes a mounting base, a structure for securing the mounting base to the stringed musical instrument, a housing body to provide a space to accommodate tuning mechanisms, a plurality of control rod assemblies to selectively adjustment for several tunings, a plurality of tuner switch rod assemblies to provide mechanisms to switch between tunings, a set of tuning mechanisms on each control rod assembly for fine adjustment of tuning while in use, a plurality of bridge rollers to adjust height and intonation of strings, a top plate with a plurality of tuner switch screw slots that provide access to the tuner switch rod assemblies, which provide a choice from different tunings, and a lever body to relieve string tension while changing tunings.

International Classification:

G10D 3/04

US Classification:

84298

Abstract:

An improved stringed instrument bridge and zero fret with easily adjustable intonation mechanics for stringed instrument with a plural of saddle bodies, a wire holder tightly affixed to the saddle body securing the saddle bodies in place, the saddle body is adjusted by moving the wire holder affixed to the saddle body, a top plate body with a plural cut outs, securing the saddle bodies in place, an anchor body, with a plural of long thin screws passing through apertures in existing guitar bridge body, and into threaded apertures in the anchor body pulling everything together tightly, and providing a means for adjusting the instruments tone and amplitude, therefore this invention provides an improved instrument bridge with easily adjustable intonation that does not lose its position while changing strings or playing the instrument.

Appl. No.:

Inventors:

Curtis R. LeBlanc - Thibodaux LA, US

International Classification:

F03G 7/04
F03B 17/04

US Classification:

60325, 60327, 415916

Abstract:

A Hydraulic Gravity Harvester is disclosed; having a plural of slip buckets, each slip bucket has a piston that works with a valve that is connected to the lower end of each piston; each slip bucket reciprocates vertically within a cylinder. When the valve is in the closed position and the slip bucket is on the down stroke, it creates a positive pressure in the cylinder pushing fluid up to a reservoir positioned high above the slip buckets. Each slip bucket on the down stroke is connected so that the opposite valve is in the open position and on the up stroke, so the weight of the fluid that has pushed this slip bucket down now rest on the bottom of the cylinder. This allows the slip bucket that is on the down stroke to turn a shaft creating a rotational torque.

Inventors:

Curtis Robert LeBlanc - Thibodaux LA

International Classification:

G10D 304
G10D 314

US Classification:

84307

Abstract:

An improved, universal, multi-position, tuning mechanism and bridge for stringed musical instruments, designed to provide quick, easy adjustment of the tension of the each string of musical instruments between one of two predetermined tension levels, as well as precise adjustment mechanisms for the traditional tension settings of each string, with all components being safely housed in an easily accessible main body. The present invention includes a support plate mounted to the front surface of the body of a musical instrument. A main body and roller-type bridge are mounted to the top of the support plate. Inside the main body, a plurality of levers, spring loaded plungers and tension adjustment screws are individually adjustable to vary the tension in each string. A multi-tuning lever arm adjusts the tension of the each string between one of two predetermined tension levels. A lever arm adjustment means allows quick and precise adjustment of the tension in each of these two pre-determined settings.
