page_text: LETTERS PATENT to James Stewart, of St. Paul's Road, Cambden
Square, in the County of Middlesex, Pianoforte Maker, for the
Lavention of Tamar
Sealed the 27th October 1853, and dated the 16th August 1853.
PROVISIONAL SPECIFICATION left by the said James Stewart at
the Office of the Commissioners of Patents, with his Petition,
on the 16th August 1853.
I, JAMES STEWART, of Saint Paul's Road, Cambden Square, in the
County of Middlesex, Pianoforte Maker, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN PIANOFORTES" to be as
follows:
This Invention has for its object improvements in horizontal and
upright pianofortes, and consists of obtaining a "repeat" action of the
hammer in horizontal pianofortes by fixing an upright on the key
beyond the cranked lever, and applying the button for the repeat action
to a wire fixed to the key, such wire working in a split or opening in
the head of the upright, by which arrangement the action for pro-
ducing the "repeat" is made independent of the cranked lever; and in

page_text: upright pianofortes the lower end of the sticker is glued or fixed
directly to the fore end of the lever, which is in two parts, which
are hinged together, the back end being hinged to the lever rail as
heretofore.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Stewart in the Great Seal Patent Office
on the 15th February 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JAMES STEWART, of Saint Paul's Road, Camden Square, in the County
of Middlesex, Pianoforte Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of August, in the year
of our Lord One thousand eight hundred and fifty-three, in the seven-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Stewart, Her special licence
that I, the said James Stewart, my executors, administrators, and
assigns, or such others as I, the said James Stewart, 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
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN PIANOFORTES," upon the condition (amongst others) that I, the said
James Stewart, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said Inven-
tion, 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 James Stewart, 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):
My Invention relates to improvements in the action of upright

page_text: pianofortes, and consists of causing the lower end of the sticker to be
glued or fixed directly to the fore end of the lever, which is in two
parts, which are hinged together, the back end being hinged to the
lever rail as heretofore.
Having thus stated the nature of my Invention, I will proceed to
describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
The Drawing shows a side elevation of the action of an upright
pianoforte. a, is the key; b, is the lever, which is in two parts hinged
together and to the lever rail c, by means of parchment. d, is the
sticker, which at its lower end is fixed directly to the fore part of the
lever, so that the fore part of the lever and the sticker are as if they
were one, there being no movement between them. e, is the hammer,
which receives motion from the sticker, as shewn.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that what I claim
is, the combination of parts herein described.
In witness whereof, I, the said James Stewart, have hereunto set
my hand and seal, this Fourteenth day of February, in the year
of our Lord One thousand eight hundred and fifty-four.
Witness,
FRED HARRIS.
