I, THOMAS FIRTH, of Bath Buildings, Huddersfield, Yorkshire, Stationer, do hereby
declare the nature of this invention to be as follows:-
"
This invention has reference to what are known as "book holders
and which are
used in connection with music stands (whether connected to pianofortes or separate)
for holding each slide of an open music book and preventing the leaves from turning
the object thereof being to make such "holders" adjustable so that they may be
moved nearer too or further from each other, according to size of book, that such
book-no matter how small-can be held at each corner as effectually as can a much
larger book, which cannot be done with the present fixed book holders.
over,
In order to carry out my invention I employ two pieces of metal or other suitable
material may be employed which are both mounted upon a pin or stud about midway
of their length forming a clip or jaw. One end of this clip or jaw is made to receive
a screw having a cam, tappit, or wedge, thereon, the opposite end being formed so as
to take hold of the book rest or rail of the music stand which supports the books.
The ordinary metal finger is mounted upon the cam, on which it is capable of being
turned a part of a revolution, or until it comes in contact with a stop piece on the
cam, when it commences to rotate the screw, which draws the cam, tappit or wedge
between the ends of the jaw, thereby forcing them asunder, the result being that the
opposite ends of the jaw are brought towards each other until they grip the book-rest,
or rail before mentioned.
By this means the book holders can be moved any distance too or from each other
according to the size of the book, with the greatest case.
The ends of the jaw which take hold of the book-rest can be lined or covered with
any soft material, to prevent damage to the wood work.
Small flat springs may be employed to bear against the boss of the finger so as to
hold or keep it in any position.

page_text: I THOMAS FIRTH of Bath Buildings Huddersfield Yorkshire Stationer 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 has reference to what are known as "book holders" and which are
used in connection with music stands (whether connected to pianofortes or separate)
for holding each side of an open music book and preventing the leaves from turning
over; the object thereof being to make such "holders" adjustable so that they may
be moved nearer too or further from each other, according to the size of book, so that
such book-no matter how small-can be held at each corner as effectually as a much
larger book which cannot be done with the present fixed book holder.
In order to carry out my invention I employ two pieces of metal or other suitable
material may be employed, which are both mounted upon a pin or stud, about midway
of their length, forming a clip or jaw. One end of this clip or jaw is made to receive
a screw, the opposite end being formed so as to take hold of the book rest or rail of
the music stand, which supports the books. The ordinary metal finger is mounted
upon the screw, on which it is capable of being turned a part of a revolution, or until
the jaws grip the book-rest sufficiently.
In order that my invention may be better understood reference is made to the
accompanying sheet of Drawings illustrative thereof, wherein Fig. 1. is end elevation
of my improved apparatus attached to the ordinary board in front of a piano, and on
which the music rests, Fig. 2. is end elevation, Fig. 3. another view of the apparatus
shewn detached, Fig. 4. shews another view of the apparatus, as it appears when
looking in by the arrow a, and Fig. 5 is a plan view, with the upper jaw removed.
My adjustable book holder is composed of an upper jaw and a lower jaw e as shewn
detached in Fig. 6. The jaws and e are connected together by a pin. or stud d
through the centre of which is a hole tapped to receive a screw thread formed on the
end of the conical part e which is also made to carry the ordinary metal music
supporting finger f
The open jaws of these adjustable music holders are placed onto the book-rest g and
can be slided end-wise thereon to any position required according to the size of book
in front of the performer; when this is done, the finger fis screwed around one or two
turns in such manner as to cause the conical or taper part e to open the end of the
jaws against which they are in contact, but the opposite end of the said jaws will close
upon and grip the music rest g so as to be firm, steady, and stationary whilst by a
turn or two of the finger f the jaws are slackened which whilst not loose enough as to

page_text: fall off the book rest, the said jaws are sufficiently loose as to permitt them being slided
endwise on the book rest, to suit another size of book whether it be large or small.
The inside of the jaws can, if thought necessary, be lined or covered with some soft
material so as not to damage the book rest g.
If desirable I may use small flat steel springs placed between the conical part e
and the finger so as to make the parts tight and prevent the finer f from falling
when once it is placed into any required position.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
The adjustable book holder, composed of jaws such as b and c operated or opened
and closed in the manner substantially as herein shewn and described.
