IMPROVEMENTS IN THE MANUFACTURE OF CON- CERTINAS, ORGANS, AND HARMONIUMS.”
Year: 1875

page_text: LETTERS PATENT to Frederic William Docrfel Steinfelser, of Klin-
genthal, Musical Instrument Maker, Partner of the Firm C F.
Docrfel Steinfelser & Co, in Klingenthal, in the Kingdom of Saxony,
for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF CON-
CERTINAS, ORGANS, AND HARMONIUMS.”
PROVISIONAL SPECIFICATION left by the said Frederic William
Doerfel Steinfelser at the Office of the Commissioners of Patents,
with his Petition, on the 12th April 1875.
I, FREDERIC WILLIAM DOERFEL STEINFELSER, of Klingenthal, Musical
Instrument Maker, Partner of the Firm C F. Doerfel Steinfelser & Co.,
in Klingenthal, in the Kingdom of Saxony, do hereby declare the nature
of the said Invention for " IMPROVEMENTS IN THE MANUFACTURE OF CONCER-
TINAS, ORGANS, AND HARMONIUMS," to be as follows:-

page_text: And, Second. To construct some parts of concertinas in such a manner
that such parts may be taken asunder with greater facility than hereto-
fore when it is required to obtain access to the interior of the instrument
for repairs or otherwise.
The first improvement consists in constructing the sound board of
concertinas, organs, harmoniums, and other free reed instruments of
glass instead of wood, as has heretofore been the case. In carrying out
this part of my Invention I take a plate of glass of the proper shape,
and after making the necessary perforations therein I adapt thereto or
secure thereon in any convenient manner the tongues or vibrators,
together with the spring levers, keys, and other of the ordinary working,
parts of the instruments. By substituting glass for wood in the con-
struction of the sound board the tone-of the instrument is very much
improved, and is softer and sweeter than in the ordinary instruments.
"
In concertinas of the ordinary construction the wooden end plates (or
tops," as they are usually denominated) are fixed on by screws, so that
they cannot be removed without the use of a screwdriver to withdraw
the screws.
The second improvement consists in making the wooden ends of
concertinas in two parts, consisting of a box and lid. The lid or "top"
is attached to the box by means of a hinge or hinges, and when the parts
are closed they are made secure by means of a spring catch and hooks
or other suitable fastenings.
By constructing the instrument in this manner the top can be opened
with facility, and access easily obtained to the working parts. Instead
of the "box" being glued to the "bellows" part of the instrument, as
herotofore, it is secured thereto by means of blocks and wedges, so that
these parts can be taken asunder by simply removing the wedges. By
this arrangement of parts greater facility is obtained for repairing the
bellows, or for replacing a worn out one by a new bellows.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederic William Doerfel Steinfelser in the Great
Scal Patent Office on the 12th October 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERIC
WILLIAM DOERFEL STEINFELSER, of Klingenthal, Musical Instrument
Maker, of the Firm of O. F. Doerfel Steinfelser & Co., of Klingenthal, in
the Kingdom of Saxony, send greeting
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of April, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
cighth year of Her reign, did, for Herself, Her hours and successors,
give and grant unto me, the said Frederic William Docrfel Steinfelser,
Пer special licence that I, the said Frederic William Docrfel Steinfelser,
my executors, administrators, and assigns, or such others as I, the said
Frederic William Doerfel Steinfelser, 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, uso, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for " 'İMPROVEMENTS IN the Manufacture
OF CONCERTINAS, ORGANS, AND HARMONIUMS," upon the condition (amongst
others) that I, the said Frederic William Doerfel Steinfelser, 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 immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Frederic William Doerfel Steinfelser,
do hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the Drawing
hereunto annexed and to the letters and figures marked thereon (that is
to say):-

page_text: sound board cannot move. Holes are made in the usual manner in the
lid a of the box for the ivory studs (whereby the keys are depressed)
to pass through, as is well known.
In concertinas of the ordinary construction the wooden end plates (or
tops as they are usually denominated) are fixed on by screws, so that
they cannot be removed without the use of a screwdriver to withdraw
the screws
The second improvement consists in making the wooden ends or tops
of concertinas in two parts, consisting of a box f and lid a, as shown
in the Figures. The lid or "top" is attached to the box by means of a
binge or hinges, and when the parts are closed they are made secure by
means of the spring catch a* and the hooks f¹, f¹, as already explained,
or by other suitable fastenings
By constructing the instrument in this manner the top can be opened
with facility by simply undoing the hooks f¹, f, and pushing back the
spring catch a*, when access can casily be obtained to the working parts,
as when the lid a is raised the glass sound board & with all the working
parts can be lifted off its scat. Instead of the box being glued to the
"bellows" parts of the instrument, as heretofore, it is secured thereto
by means of blocks y provided with tongues 9', which pass through
staples or sockets & secured inside the top, the two parts being held
together by means of wedges 2, 2, so that these parts can be taken
asunder by simply removing the wedges 2. By this arrangement of parts
greater facility is obtained for repairing the bellows 3, or for replacing a
worn out one by a new bellows.
Having now described my Invention of "Improvements in the Manu-
facture of Concertinas, Organs, and Harmoniums," and having explained
the manner of carrying the same into effect, I claim as the Invention
secured to me by Letters Patent as aforesaid,—
First. Constructing the sound board of concertinas, organs, harmo-
niums, and other free reed instruments of glass instead of wood, as herein
set forth.
Second. Constructing the wooden ends or tops of concertinas in two
parts, consisting of a box and lid, and attaching the same to the instru-
5 ment, as and for the purpose herein set forth.

page_text: Third. I claim attaching or securing the bellows part of concertinas
to the box parts of the instrument by means of blocks and wedges, as
herein set forth, so that these parts can be taken asunder with facility
by simply removing the wedges.
In witness whereof, I, the said Frederic William Doerfel Steinfelser,
herein set forth, so that these parts can be taken asunder with facility
by simply removing the wedges.
In witness whereof, I, the said Frederic William Doerfel Steinfelser,
have hereunto set my hand and scal, the Eleventh day of October,
in the year of our Lord One thousand cight hundred and seventy-
five
