COMPLETE SPECIFICATION.
Hot-air Apparatus for the Prevention of Damp in the Interior of
Organs, Harmoniums, and Pianos.
I, WILLIAM HEYGATE BUTLIN of The Vicarage, Leonard Stanley, Stonehouse
Gloucestershire, 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:-
In carrying out my Invention I affix a tube or flue of suitable material immediately
above a lamp or gas jet in such a manner that the heat from the same may enter the
said tube and pass through it. After arranging the lamp or gas jet in a suitable
position conduct the said flue round about, under, or otherwise in close proximity to,
an organ for example, ultimately allowing an outlet at a suitable juncture. The heat
generated by the said flue dispels from and prevents dampness in, the interior of
organs &c. and thus serves to keep the same in good order in places where it is not
always convenient to have the ordinary heating methods for the whole room where the
instrument is located.
In the annexed Drawing Fig. 1 shews a general view of the apparatus: A is the
flame from an ordinary lamp or gas jet B is the chimney thereon; D is the tube or
flue to conduct the heat generated by the said flame; C shews how the chimney
enters the tube D the zigzag line on D representing a part thereof broken away so as
to exhibit the said chimney to the observer.
Fig. 2 illustrates in section an additional covering for a portion of the flue x to 2ª
where the heat is greatest. K is the interior of the Hue; D is the flue; D¹ represents
the additional tube and H. H. is a composition to prevent the heat from being too
strong.
Fig. 1 by D. D. D. shews the direction the flue may be taken, in an organ for
example, to pass under the manuals or round them as desired, and back again under
the backfalls before the heat is allowed to escape at E which latter may be arranged
at any convenient place.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is
(1) A flue for conducting heat, from an ordinary lamp or gas jet, round, through
or about organs, harmoniums and pianos to prevent dampness in the interiors thereof,
and

page_text: (2) The construction of the end of the flue near to the said lamp or gas jet with
double tubing and a composition of a non-conducting character between the two tubes,
substantially as hereinbefore described and set forth.
Dated this 3rd day of December 1889.
