Year: 1861

page_text: LETTERS PATENT to Philip Jewell, of Bond Street, Brighton, Musical,
Instrument Maker, for the Invention of "IMPROVEMENTS IN CONCERTINAS."
Sealed the 11th February 1862, and dated the 29th August 1861.
PROVISIONAL SPECIFICATION left by the said Philip Jewell at the
Office of the Commissioners of Patents, with his Petition, on the 29th
August 1861.
I, PHILIP JEWELL, of Bond Street, Brighton, Musical Instrument Maker,
do hereby declare the nature of the Invention for "IMPROVEMENTS IN CON-
CERTINAS," to be as follows:-
This Invention has for its object improvements in concertinas. It is well
known that in German concertinas each stud according as it is acted upon
by the finger of the player, in one of two modes, is capable of sounding one or
other of two natural notes, and it is customary to employ two rows of such.
studs with suitable mechanism to be acted on thereby at each end of a Ger-
man concertina, though in some instruments more than two rows of studs.
are used, and although, apparatus for sounding the semi-tones have been
applied to other constructions of concertinas, it has not been usual to apply.
mechanism. to German concertinas, to enable the semi-tones as well as the
natural notes to be sounded thereby.
Now part of my Invention consists in applying an additional row of studs

page_text: at each end of a German concertina, in combination with suitable mechanism
for sounding the semi-tones, cach stud of such additional row being arranged
in such manner that it will, when suitably acted on, sound one or other of two
semi-tones.
And another part of my Invention consists in applying to German and
other concertinas, parallel plates of glass, interior of the instruments, opposite,
but at a short distance from the holes or air passages, by which the tones of
the instruments will be modified and improved.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Philip Jewell in the Great Seal Patent Office on the 28th
February 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PHILIP
JEWELL, of Bond Street, Brighton, Musical Instrument Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of August, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Philip Jewell, Hor special licence that I, tho said Philip
Jewell, my executors, administrators, and assigns, or such others as I, the
said Philip. Jewell, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Chaunel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN CONCERTINAS," upon the condition (amongst others) that
I, the said Philip Jewell, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to. be filed
in the Great Seal Patent-Office within six calendar months.next and imme-
diately after the date of the said Eetters. Patent.
NOW KNOW YE; that I, the said Philip Jewell, do hereby declare
the nature of the said Invention, and in what manner the same. is. to. be.
performed, to be particularly described and ascertained in and by the.
following statement thereof, that is to say:
This Invention has for its object improvements in concertinas. It is well

page_text: known that in German concertinas, each stud, according as it is acted upon by
the finger of the player, in one of two modes, is capable of sounding one or
other of two natural notes, and it is customary to employ two rows of such
studs, with suitable mechanism to be acted on, thereby at each end of a Ger-
man concertina, though in some instruments more than two rows of studs are
used, and although apparatus for sounding the semi-tones of the chromatic
scales have been applied to other constructions of concertinas, it has not
been usual to apply mechanism to German concertinas, to enable the semi-
tones of the chromatic scales, as well as the natural notes to be sounded
thereby.
Now part of my Invention consists in applying an additional row of studs
at each end of a German concertina, in combination with suitable mechanism
for sounding the semi-tones of the chromatic scales, each stud of such additional
row being arranged in such manner that it will, when suitably acted on,
sound one or other of two semi-tones.

And another part of my Invention consists in applying to German and
other concertinas, parallel plates of glass interior of the instruments, opposite,
but at a short distance from the holes or air passages by which the tones of the
instruments will be modified and improved.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
Figures 1 and 2 shew the two end views of a concertina, constructed
according to my Invention; Figure 3 shews a section, and Figure 4 an
under side view, of one of the ends, where plates of glass are applied over the
air passages, in order to modify and improve the tone. The instrument, the
ends of which are shown in the Drawing, is constructed in the ordinary
manner, so far as concerns the natural notes, and the keys and mechanism by
which those notes are caused to be sounded; these ordinary keys are shown
white in the Drawing, each key as is well understood being arranged by the
interposed mechanism to sound either of two natural notes, according to the
manner in which that key is acted on by the finger of the person playing the
instrument. In addition to the natural notes there is an extra row of keys
at each end of the instrument in combination with like mechanism to what is
used for. sounding the natural notes, in order that the semi-tones of the
chromatic scales may also be sounded by the instrument, the keys used for
the semi-tones are in the Drawing colored red, and in the instrument itself
are denoted by black or other distinctive color; these keys are arranged in
such manner that each key by suitable interposed mechanism may sound
either of two semi-tones according to the manner in which the key is acted on
'

page_text: by the finger of the person playing the instrument. The peculiarity of this
part of the Invention consists in applying in German concertinas keys and
mechanism for sounding the semi-tones of the chromatic scales, each key
being arranged to act on the mechanism of two semi-tones. Figure 3 is a
transverse section, and Figure 4 an under side view, of one of tho ends
of a concertina with glass plates applied over the vibraters, and between
them and the apertures by which the sound escapes; a; a, are two parallel
plates of glass, these plates aro kept at a short distance from each other, and
from the ends of the instrument. The peculiarity of this part of the Invention
consists in applying the plates of glass a, a, at each end of the instrument as
described.
In witness whereof, I, tho said Philip Jewell, have hereunto set my
hand and seal, this Twenty-sixth day of February, in the year of our
Lord One thousand eight hundred and sixty-two.
