PROVISIONAL SPECIFICATION.
An Improvement in Flutes and Flageolet Whistles.
I, FREDERICK SEAMAN, of 6, Rothbury Road, White Post Lane, Victoria
Park, London, E., Musical Instrument Maker, do hereby declare the nature of
this invention to be as follows:-
This invention relates to metallic wind musical instruments of the flute and
flageolet whistle types, and it has for its object to improve the quality of the tone
of the said instruments and enable them to be readily adjusted or tuned.
The invention consists in making the head or mouth piece of the instrument of
larger internal diameter than the bore of the cylinder body or finger-hole piece,
and connecting the two parts of the instrument by a telescopically-sliding joint
permitting of adjusting the length of the instrument for tuning purposes.
Both parts of the instrument are drawn of thin sheet metal and the socket end
of the head or mouth piece is contracted to suit the diameter of the end of the
cylinder body or finger-hole piece which fits therein.
Dated this 14th day of February 1891.

COMPLETE SPECIFICATION.
An Improvement in Flutes and Flageolet Whistles.
I, FREDERICK SEAMAN, of 6, Rothbury Road, White Post Lane, Victoria
Park, London, E., Musical Instrument Maker, do hereby declare the nature of
this invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to metallic wind musical instruments of the flute and
flageolet whistle types; and it has for its object to improve the quality of the tone
of the said instruments and enable them to be readily adjusted for pitch.
Reference is to be had to the accompanying drawings, forming part of this
Specification, wherein Figure 1 is a part sectional longitudinal view of a flageolet
whistle, and Figure 2 is a corresponding view of a flute, both constructed
according to my invention.
The invention consists in making the head or mouth-piece a of the instrument
separate from, and of larger internal diameter than, the cylinder body or finger-
hole piece and in connecting the two parts a b of the instrument by a tele-
scopically-sliding joint permitting of adjusting the length of the instrument for the
purpose of varying the pitch.
This joint is formed by a socket a¹ in the end of the head or mouth piece a in
which fits friction tight the end 6' of the finger-hole piece, the inward sliding being
limited by a shoulder b³.
Both parts a b of the instrument are drawn of thin sheet metal and the head or
mouth piece a may be of still greater diameter relatively to the finger-hole piece b,
its socket end a¹ being in that case contracted to suit the diameter of the end of
the cylinder body or finger-hole piece which fits therein.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The herein described improvement in metal flutes and flageolet whistles, which

page_text: consists in making the head or mouth-piece separate from, and of larger diameter
than, the cylinder or finger-hole piece and uniting the two parts by a telescopically-
sliding joint, as described.
