Improvements ir Pianofortes, Zithers and the like.
I ALFRED GEORGE BROWNE of 81 Linnæus Street Hull in the County of York,
Company's Manager do hereby declare the, nature of this invention to be as
follows:-
According to the first part of my invention I make the plug holes in the solid
metal wrest plank of two sizes the longer and larger to receive the plug and the
smaller through sufficient metal at the back to give the plug a bearing which will
prevent the plug being driven out at the back and assist the lug of the plug in
resisting the force brought to bear upon it when the wrest pin is being driven into
the plug the smaller hole to be sufficiently large to admit of a broken wrest pin being
driven through the plug from front to back of wrest plank.
According to the second part of my invention I cast a Trench or grove in the
wrest plank into which I insert the bridge in one piece or in sections with suitable
Trenches or Groves and fitted in such a manner that the down bearing of the strings
will be sufficient to keep the bridge in its place without the aid of screws the Bridges
may be made of solid or hollow steel or wood or other suitable material.
According to the third part of my invention I make a resonating chamber by
employing two sounding boards or Bellies in such a manner that each string passes
over the two divisions of the bridge with equal down bearing on each although one
half of the bridge is fixed to the back sounding board and the other half to the front
sounding board the two halves may be fastened together or remain quite independent
of each other except so far as the strings connect each half of the bridge by passing
equally over both I may connect the two sounding boards by means of circular belly
bars or give the front sounding board a bearing on the bridge of the back sounding
board and finish the bridge to the required height on the front sounding board.

I ALFRED GEORGE BROWNE of 81 Linnæus Street Hull in the County of Yorks
Company's Manager, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to certain improvements in the formation of holes in solid
metal wrest planks and the manner of fixing plugs therein which will be better
understood by reference to the accompanying drawing. According to my invention
I make holes in solid metal wrest planks A A of two sizes the longer and larger

page_text: hole receives plug B. B and the smaller hole 1) admits of wrestpin C being driven
through from front to back, plug B B is supported by parts F F of wrest plank AA
which assists plug B B and lug E to resist undue force which may be used when
driving plug B B and wrest pin C home to their respective positions.
Having now particularly described and
invention and in what manner the same is to
claim is
ascertained the nature of this
performed I declare that what I
The use of solid metal wrest plank A A and plugs B B resting on parts F F of
wrest plank A A and the hole D which allows wrest pin C to be driven out at the
back substantially as shown and described.
