Mouthpiece for wind instruments

Claim 2

A mouthpiece for wind instruments, comprising an elongated substantially tubular composite body member having an end adapted to be pressed against the lips of a user, said body member including in the region of said end an inner surface which diverges in a direction away from said end, a first substantially tubular insert member removably accommodated in said body member and spaced from said end; and a second substantially annular insert member interposed between said first insert member and said end and being centered by said first insert member, said second insert member having a complementary surface which sealingly abuts said inner surface, and said body member being provided with at least one lateral opening communicating with the interior thereof so as to permit insertion and removal of said first and second insert members.

Claim 3

A mouthpiece for brass wind instruments, comprising an elongated substantially tubular composite body member having an external end adapted to be pressed against the lips of a user and an opposite end adapted to be connected with one of said instruments, the interior of said body member including an inner surface which diverges in a direction away from said external end, a chamber having an inner surface configurated to receive and position inserts, and a first passage extending through said opposite end for passing vibrations from said user''s lips into said one instrument; a first substantially tubular insert member having a second passage therethrough, said first insert member being inserted into said chamber and centered thereby, effecting smooth mating of said second passage and said first passage; and a second substantially annular insert member having a third passage therethrough and a centering portion complementary to a portion of said first insert member, said second insert member being interposed between said first insert member and said external end and being centered by said first insert member and effecting smooth mating of said third passage and said second passage, and said second insert member having a surface complementary with said body member inner surface and which sealingly abuts said body member inner surface.

Claim 4

A mouthpiece for brass wind instruments, comprising an elongated substantially tubular composite body member having an external end adapted to be pressed against the lips of a user and an opposite end adapted to be connected with one of said instruments, the interior of said body member including an inner surface which diverges in a direction away from said external end, a chamber having an inner surface configurated to receive and position inserts, and a first passage extending through said opposite end for passing vibrations from said user''s lips into said one instrument; a first substantially tubular insert member having a second passage therethrough, said first insert member being inserted into said chamber and centered thereby, effecting smooth mating of said second passage and said first passage; and a second substantially annular insert member having a third passage therethrough and a centering portion complementary to a portion of said first insert member, said second insert member being interposed between said first insert member and said external end and being centered by said first insert member and effecting smooth mating of said third passage and said second passage, and said second insert member having a surface complementary with said body member inner surface and which sealingly abuts said body member inner surface.

Claim 5

A mouthpiece as defined in claim 2, wherein said complementary surfaces of said body member and said second insert member are substantially conical.

Claim 6

A mouthpiece as defined in claim 2, wherein said complementary surfaces of said body member and said second insert member are substantially spherical.

Claim 7

A mouthpiece as defined in claim 2, wherein said portion of said first insert member receives said centering portion, said centering portion having a length greater than that of said portion of said first insert member.

Claim 8

A mouthpiece as defined in claim 5, wherein said portion of said first insert member comprises a plurality of elastically yieldable members extending along the elongation of said body member for firmly securing said centering portion.

Claim 9

A mouthpiece as defined in claim 2, wherein said first insert member comprises a centering portion received by said chamber, the length of said centering portion of said first insert member being greater than that of said chamber.

Claim 10

A mouthpiece as defined in claim 2, wherein said body member comprises two discrete body sections each of which is provided with a flange portion extending in substantially radial direction of said body member, said flange portions being spaced from one another in axial direction of said body member and at least in part overlyng one another, said flange portions and said body sections together defining a space intermediate the latter; and further comprising biasing means in said space bearing against said flange portions and biasing said body sections relative to each other in axial direction of said body member to thereby urge said complementary surfaces of said body member and said second insert member, and said first and second insert members, into firm engagement.

Claim 11

A mouthpiece as defined in claim 2, wherein said portion of said first insert member is integral therewith.

Claim 12

A mouthpiece as defined in claim 2, wherein said body member comprises two discrete body sections adapted to become engaged when moved relative to each other in axial direction of said body member.

Claim 13

A mouthpiece as defined in claim 10, wherein said external end comprises a rim adapted to be pressed against the lips of a user, said rim being integral with one of said body sections.

Claim 14

A mouthpiece as defined in claim 10, wherein said first insert member has a substantially concial surface facing away from said external end, one of said body sections having a substantially conical complementary surface abutting said conical surface of said first insert member for centering said first insert member.

Claim 15

A mouthpiece as defined in claim 10, wherein said first insert member has a substantially spherical surface facing away from said external end, one of said body sections having a substantially spherical complementary surface abutting said spherical surface of said first insert member for centering said first insert member.

Claim 16

A mouthpiece as defined in claim 10, wherein said body sections are provided with mating threads for engagement thereof.

Claim 17

A mouthpiece as defined in claim 10; and further comprising means for biasing said body sections relative to each other in the axial direction of said body member to thereby urge said complementary surfaces of said body member and said second insert member, and said first and second insert members, into firm engagement.

Claim 18

A mouthpiece as defined in claim 2, wherein said first insert member has a face remote from said external end and abutting an adjacent face of said second insert member, said first insert member being interchangeable with other first insert members and said second insert member being interchangeable with other second insert members, the passages of all of said first and second insert members at said faces being substantially identical.
