Instruments.
FREDERICK DEARE and JAMES HENRY LEE, Docwras Buildings, King
Henry's Walk, Balls Pond Road, London, N., Pianoforte Manufacturers, do hereby
declare the nature of this invention to-be as follows:—
"
Our invention refers to a new & improved forked bridge pin made out of a
piece of metal with two and three prongs combined in one note, for sustaining &
regulating the tension of the strings used for pianofortes & any other musical
instruments. To be made in any metal or metals.
Dated this Fourth day of February 1897.

Improvements in Bridge Pins for Pianofortes and other Musical
Instruments.
FREDERICK DEARE and JAMES HENRY LEE, of Docwras Buildings, King
Henry's Walk, Balls Pond Road, London, N., Pianoforte Manufacturers, lo hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
The object of our invention is to prevent bridge pins for pianofortes and other
musical instruments from becoming bent by the pressure of the strings against
them.
This object we attain by forming the bridge pins for bicord and tricord
instruments with two and three prongs respectively connected together by a
bridge-piece.
And in order that our said invention may be fully understood we will proceed
to explain the same with reference to the accompanying sheet of drawings in
which:
Fig. 1. represents front view of our improved bridge-pin suitable for tricord
instruments.
Fig. 2. represents front view of our improved bridge-pin for bicord instruments.
Fig. 3. is side view of our improved pin.
Fig. 4. is section through bridge shewing pin in position.
Fig. 5. shews how the strings are led through the pins.

page_text: The same letters denote the same parts in all the Figs.
As will be seen on referring to the drawings Figs. 1, 4, 5, instead of using a
separate pin for each string as heretofore we make all the pins for each note in
one piece the pins for tricords being made of prongs a. b. c connected by bridge
pieces d d.
The pins may be made from any suitable material by stamping, forging or
casting preferably by stamping from sheet metal.
As will be seen on reference to Figs. 4 and 5 two of the strings are threaded
through the openings between the prongs while the third string rests against the
outer edge of the third prong.
The improved bridge pins are driven through the bridges f into the wrest
planks 9.
The edges of the pins against which the strings bear may be square or rounded.
In the case of pins for bicords two prongs only a b are required such pins may
be made from stamped metal or from wire bent into the required shape.
Bridge pins constructed as hereinbefore specified are much stronger than the
wire pins hitherto adopted and will not bend in use.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is-
1. Bridge pins for pianofortes and other stringed instruments consisting of two
or more prongs connected together by one or more bridge pieces as herein before
specified.
2. In bridge pins for stringed musical instruments the combination of two or
more prongs such as a be with bridge pieces such as d substantially as herein-
before specified and for the purpose stated.
3. Bridge pins for stringed musical instruments constructed as shewn by the
accompanying drawings.
