Apparatus for locating sections of a wind instrument

A musical wind instrument comprising:

• a first section and a second section;
• engagement means on said first and second sections respectively for telescopically interfitting said first section and second section to define an assembled condition thereof;
• and alignment and locating means located respectively on said first section and said second section for defining a predetermined orientation therebetween when interfitted into assembled condition, said alignment and locating means including an axially projecting member mounted on a peripheral surface of one of said first and second sections, and an axially inwardly extending recess in the other of said first and second sections of complementary form for receiving at least a portion of said projecting member when said first and second sections are telescopically interfitted and brought into a desired radial alignment and fully axially and telescopically engaged;
• said engagement means of said first section being generally cylindrical and hollow in form and of a given outer diameter for joining with the engagement means of said second section;
• wherein said engagement means of said second section is generally cylindrical and hollow in form, having an inner diameter substantially similar to the outer diameter of said first section engagement means for receiving the same axially telescopically interfitted therewithin, and respective axially outwardly facing abutment surfaces formed adjacent said engagement means of said first and second sections, said abutment surfaces being located in face-to-face abutting condition when the two sections are pressed together in assembled condition;
• wherein said projecting member projects from one of said abutment surfaces and wherein said recess means for receiving the same is recessed into the other of said abutment surfaces;
• wherein said projecting member is stepped radially inwardly;
• and wherein said other of said abutment surfaces has an outwardly extending portion which overlies said complementary recess and said stepped down portion of said projecting member when the same is brought into full engagement with the complementary recess, such that an axially outwardly facing surface of said projecting member defined by said stepped down portion thereof is brought together in facing and abutting condition with an axially outwardly facing end surface of said outwardly extending portion.
