Abstract
Abstract A mouthpiece for a musical instrument having a body member with a tapered tubular backbore at one end engageable to fit a musical instrument and a cup and rim at its opposite end, each of which is detachably maintained together to form the mouthpiece. The cup is provided with a plurality of annular internal sections to create a predetermined resistance to air flow through the mouthpiece thereby controlling the tone produced with a change of the axial length of the sections resulting in a change in resistance and accordingly the tone.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
100 words
A mouthpiece for a musical instrument, said mouthpiece comprising: a body member having a tapered tubular backbore at one end engageable to fit a musical instrument and a cup and rim at its opposite end; said cup including a plurality of annular internal sections providing a predetermined resistance to air flow through the mouthpiece controlling the tone produced thereby with a change of the axial length of said sections resulting in a change in said resistance and accordingly said tone, each section being disposed at an angle of approximately 15° difference with respect to the angularity of sections adjacent thereto.
Claim 2
Dependent Claim
100 words
A mouthpiece for a musical instrument, said mouthpiece comprising: a body member having a tapered tubular backbore at one end engageable to fit a musical instrument and a cup and rim at its opposite end; said cup including a plurality of annular internal sections providing a predetermined resistance to air flow through the mouthpiece controlling the tone produced thereby with a change of the axial length of said sections resulting in a change in said resistance and accordingly said tone, each section being disposed at an angle of approximately 15° difference with respect to the angularity of sections adjacent thereto.
Claim 3
Dependent Claim
49 words
The invention in accordance with claim 1 wherein said cup includes at least three adjacent sections disposed at predetermined angularity with respect to the mouthpiece's longitudinal axis, a second section disposed between a first and third section balancing the effect the first and third sections have on the tone.
Claim 4
Dependent Claim
35 words
The invention in accordance with claim 2 which includes a fourth section adjacent said rim and said third section of an angle and axial length of which determines the amount of air entering the mouthpiece.
Claim 5
Dependent Claim
26 words
The invention in accordance with claim 3 wherein said fourth section is disposed at an angle of approximately 60° with respect to the mouthpiece's longitudinal axis.
Claim 6
Dependent Claim
38 words
The invention in accordance with claims 1, 2, 3 or 4 wherein said rim, cup and backbore are each separate parts of the mouthpiece, detachably maintained together by screw-thread portions between the rim and cup; cup and backbore.
Claim 7
Dependent Claim
107 words
A mouthpiece for a musical instrument, said mouthpiece comprising: a body member having a longitudinal axis and a tapered tubular backbone at one end engageable to fit a musical instrument and a cup and rim at its opposite end; said cup including at least three annular internal sections providing a predetermined resistance to air flow through the mouthpiece controlling the tone produced thereby with a change of the axial length of said sections resulting in a change in said resistance and accordingly said tone, the annular internal sections each being circular and progressively increasing in angularity relative to the longitudinal axis from the backbore to the rim.
Claim 8
Dependent Claim
107 words
A mouthpiece for a musical instrument, said mouthpiece comprising: a body member having a longitudinal axis and a tapered tubular backbone at one end engageable to fit a musical instrument and a cup and rim at its opposite end; said cup including at least three annular internal sections providing a predetermined resistance to air flow through the mouthpiece controlling the tone produced thereby with a change of the axial length of said sections resulting in a change in said resistance and accordingly said tone, the annular internal sections each being circular and progressively increasing in angularity relative to the longitudinal axis from the backbore to the rim.
