Abstract
Abstract A mouthpiece, particularly for the orchestral brass instruments having an invert lay, whereby the ridge, or high spot, of the rim of the mouthpiece is sensed by the instrument player as being nearer the rim periphery than to the mouthpiece cup. The contour of the mouthpiece, in axial cross-section, provides a radiused transition region from the mouthpiece rim to the outer periphery and a further radiused transition region from the mouthpiece rim to the inner cup. Therebetween is a flat region which is downwardly inclined in the inward direction, so providing the rim with a circular ridge which is nearer to the periphery than to the cup.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
46 words
A mouthpiece for a musical instrument comprising a rim having a contour with a flattened region, intermediate the highest part of the rim and the inner cup, which is downwardly inclined towards the cup, thereby providing an invert lay of the mouthpiece against the player''s lips.
Claim 2
Dependent Claim
46 words
A mouthpiece for a musical instrument comprising a rim having a contour with a flattened region, intermediate the highest part of the rim and the inner cup, which is downwardly inclined towards the cup, thereby providing an invert lay of the mouthpiece against the player''s lips.
Claim 3
Dependent Claim
26 words
A mouthpiece as claimed in claim 1, in which the flattened region is slightly flared outwardly from the cup to the highest part of the rim.
Claim 4
Dependent Claim
22 words
A mouthpiece as claimed in claim 1, in which the flattened region is downwardly inclined at an angle between 4* and 6*.
Claim 5
Dependent Claim
37 words
A mouthpiece as claimed in claim 1, in which the flattened region forms a part of the surface of a cone and has a uniform angle of downward inclination not less than 4* and not exceeding 6*.
Claim 6
Dependent Claim
25 words
A mouthpiece as claimed in claim 2, in which the angle of downward inclination of the flared surface varies, but is nowhere less than 4*.
Claim 7
Dependent Claim
30 words
A mouthpiece as claimed in claim 1, having a rim contour such that the highest part of the rim lies nearer to the outer periphery than to the inner cup.
Claim 8
Dependent Claim
49 words
A mouthpiece as claimed in claim 1, in which the radial distance of the rim, from the cup to the outer periphery, is between 10 millimeters and 15 millimeters and the highest point, or ridge, of the rim is located at approximately one-third this distance from the outer periphery.
