We HENRY DAVIES GROVES, Mechanical Draughtsman, and CHARLES EDWARD
GROVES Clerk, both of St. Paul's Road Manningham in the county of York, do
hereby declare the nature of this Invention to be as follows :-
:-
The object of our invention is to construct adjustable supports for any size of books
for pianofortes, organs, reading rests, music stands, and other appliances for holding
books open, these objects are obtained as follows:-
We secure by screws or other means to the front of the ordinary book rests a metal
bar on which are placed two or more metal collars, which can be slid or moved along
the bar, and have a slight projection to fit under the book rest; in the collars at
right angles to the bar is tapped a hole to receive a screw, to which is attached a
finger for holding the leaves in position; the bar may be supported in the centre by
an eyelet hook or other suitable support. Or instead of the ordinary book rest, we
may use a frame composed of two parallel metal bars, connected at the ends, where
they are hinged to the lid of the instrument, or to the music stand, or other appliance
for holding books open, along which parallel bars slide, the collars and fingers, before
described, in this case, the collar forms an additional support to the book. The action
is as follows:-On using a book of any size, the fingers are turned down releasing the
collars, so that they slide loose along the bar to the required positions; the fingers
are then turned up, and the collars will thus be secured in position. A suitable
arrangement is used to prevent the fingers falling below a horizontal position when
not in use.
By this means the difficulty of holding open the leaves of various sized books by
fixed fingers is obviated.

We HENRY DAVIES GROVES Mechanical Draughtsman and CHARLES EDWARD
GROVES Clerk both of St. Pauls Road Manningham in the County of York 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:-
The object of our invention is to construct adjustable supports for any size of
books, for pianofortes, organs, reading rests, music stands, and other appliances used
for holding books onen.

Fig. 11. is a sectional view of collar shewing the action of screw and washer.
We secure by screws or other means to the front edge of the ordinary book rests
(see Figs. 1 and 2) a metal bar or rod A, on which are placed two or more metal
collars B, which can be slid or moved along the rod A, and have a slight projection
to fit under the book rest, in the collars B, at right angles to the bar is tapped a
hole C, to receive a screw D, to which is attached the finger E, for holding the leaves
in position, the bar may be supported in the centre by an eyelet hook F, or by other
suitable support.
Instead of the ordinary book rest we may use a frame composed of two parallel
rods A, and A', (see Figs. 5 and 6) connected at the ends where they are hinged to
the lid of the instrument, to prevent spoiling the lid or small projection L, is cast to
the hinge for the elbow of the rod to abat against, along these parallel rods slide the
elongated collars B', and the fingers E, before described, in this case the collars form
an additional support to the book. Or we may dispense with the second rod A', and
place on the frame made by the end pieces G, and the rod A (See Figs. 2. and 3) a
brass plate H, either plain or ornamented in any suitable manner, in which case the
ordinary collars B are used with the projection made a little larger to fit firmly under
the plate H.

page_text: In connection with the arrangements shewn at Figs. 3. 4. 5 and 6 I use a catch J,
to secure them to the instrument's lid when not in use (See Figs. 3 and 4) The
action is a follows:-On using a book of any size the fingers E, are turned down
releasing the collars B, by means of the screws D, so that they slide loosely along the
rod A to the required positions the fingers E, are then turned up and the collars B
will thus be secured in position.
Between the screw D, and the rod A (see Figs. 11 and 12) we use a washer K,
composed either of brass and leather, cork, or indiarubber; or of leather, cork, or
indiarubber only, which when the fingers is turned down exercises a small pressure
against the screw D. and prevents, the finger falling below the horizontal position
when not in use, and also prevents the metal screw from coming in contact with the rod,
and scratching it. For the same purpose I may cut a small groove M one quarter
round the face of the collars B (see Fig. 9A sheet 1.) into which works a pin N,
attached to screw D, which will not allow it to pass further round, than from the
vertical to the horizontal position and vice versa. The collars B may be round or
square or any suitable shape, either plain or engraved or ornamented in any manner
which may seem suitable.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :-
1. In book rests the combination of sliding collars B (with projections) fingers E
and screws D adjustable upon rods, as and for the purposes shewn and described.
2. The combination of the double slides B', fingers E and screws D, adjustable upon
rods, or other bearings, as and for the purposes shewn and described.
3. In the adjustable collars or slides B and B¹ the use of a friction washer K, as
and for the purposes shewn and described.
4. In securing book rests to pianofortes and other furniture, the use of elongated
piece L on the hinges, and support J, as and for the purposes shewn and described.
