Office of the Commissioners of Patents, with his Petition, on the
8th March 1859.
I, CHARLES MILLS, of High Street, Camden Town, do hereby declare the
nature of the Invention for "IMPROVEMENTS IN THE ACTION OF PIANOFORTES,"
to be as follows:-
This Invention has for its object improvements in the action of pianofortes.
For these purposes the fly, as heretofore, is hinged at its lower end to a block
fixed on a key of an instrument, and is also, as heretofore, pressed back by a
suitable wire spring; at the front of the block is formed or fixed a stump or
projection which rises above the block, and the fly has a screw fixed into it at
a point above the hinge. The screw passes through a hole formed in the
stump or projection on the block, and has mounted on it a button or stop
which comes against the stump or projection, so as to stop the fly at the point
3 required.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Mills in the Great Seal Patent Office on the
8th September 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES

NOW KNOW YE, that I, the said Charles Mills, 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 the action of pianofortes.
For these purposes the fly, as heretofore, is hinged at its lower end to a block
fixed on a key of an instrument, and is also, as heretofore, pressed back by a
suitable wire spring. At the front of the block is formed or fixed a stump or
projection which rises above the block, and the fly. has a screw fixed into it at
a point above the hinge. The screw passes through a hole or slot formed in
the stump or projection on the block, and has mounted on it a button or stop
which comes against the stump or projection, so as to stop the fly at the point
required.
And in order that my said Invention may be most fully understood and
readily carried into effect, I will proceed to describe the Drawing hereunto
annexed.
DESCRIPTION OF THE DRAWING..
Figure 1 is a side view, and Figure 2 is a front view of a fly or hopper
arranged according to my Invention
is the hinged at al to the block h

page_text: rising from the top of the block 6; c is a spring such as is usually employed;
d is a screw fixed into the fly at a point above the hinge a', and passing
through a slot or hole in the stump or projection 6'; e is a button or stop on
the screw d, which by coming against the projection 6', limits the motion of
the fly; by turning the button or stop e it may be made to traverse along the
screw d, and it may thus be brought into a position to stop the fly a at any
required point.
In witness whereof, I, the said Charles Mills, have hereunto set my
hand and seal, this Eighth day of September, in the year of our
Lord One thousand eight hundred and fifty-nine.
C. MILLS. (..)
