FREDERICK ALBON, Engineer, 3, Lordship Road, Stoke Newington, JAMES
RICHARD YOUNG, Carpenter and Joiner, 85, Bouverie Road, Stoke Newington,
do hereby declare the nature of this invention to be as follows:-
This music turner is an appliance for attaching to a pianoforte organ, harmo-
nium or music stand. The object of this invention is to enable a player to turn
pages of music without using the hands or the assistance of a second person.
It can be made & fitted to the inside or the outside of any of the aforesaid
instruments or music stands. We make this appliance in brass aluminum or any
other metal suitable for the purpose. This appliance when attached to the
instrument or stand, can be manipulated by pressing with the foot a lever crank
or pedal which works a rod affixed to the music turner.
The lever crank or pedal is fixed at the bottom of the instrument or stand
and runs through from front to back. On the back end of this lever or pedal
we attach a rod which runs up behind the instrument on the inside or outside.
On the top end of this rod we fix a ratchet which is geared into a cog wheel on
the end of a spindle, this spindle runs across the top of the instrument from
back to front, on the front end of this spindle we fix a small bevel wheel which
is geared into another bevel wheel fixed on a spindle on the front of the instru-
ment at the same angle as the music rest, and behind the rest, on the spindle
behind the rest we fit a number of arms or wings which turn on the spindle,
over these arms or wings we fit a lever which is a fixture on the spindle behind
the rest and turns with the spindle, this spindle only turns sufficient to throw
the leaves over from right to left, the lever which is a fixture on the spindle
turns with it, the arms or wings remain lying on and between the music on
the rest, so that when the player wishes to turn over the leaf of music he presses
the lever or pedal at the bottom of the instrument with the foot which lifts the
rod at the back and works the ratchet at the top, this causes the spindle across
the instrument to revolve sufficient to turn the spindle on the front and behind
the rest, on the lever fixed to the spindle on the front we fit a drop catch so that
when it falls on the arms or wings it catches each one in turn and carries it
over to the left, this lever then turns back and remains on the next arm or wing,
the lever is taken back by means of a spring or counterbalance.

page_text: London, N., 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 improved leaf turner is an appliance for attaching to a pianoforte organ
harmoniuni or music stand.
The object of the invention is, to enable a player to turn pages of music with-
out using the hands, or the assistance of a second person. It can be made and
fitted to the inside or outside of any of the aforesaid instruments, or music stands.
We can make this appliance in any metal or substance suitable for the purpose,
such as brass, steel, wood, or vulcanite.
This appliance when fixed to a musical instrument or stand can be manipulated
by pressing with the foot a lever crank or pedal.
The method by which we effect this is shewn by the sheet of drawings accom-
panying this specification, referring to which Fig. 1 is a front view, Fig. 2, is
a side view, Fig. 3 is a plan, and Figs. 4 and 5, are enlarged' details of the pawl
and ratchet, hereafter to be described.
At a part of the musical instrument or stand convenient to the foot of the
player, we fix a lever A pivoted about the centre as shewn at B, at the back
end of this lever we attach a rod C which runs up the back, on the inside or out-
side of the musical instrument or stand, the top of this rod C, we attach to a
quadrant or ratchet D, which is geared into a cog wheel E, which is fixed onto
the end of the spindle F, which runs along the top, on the inside or outside of
the musical instrument; on the front end of this spindle F we attach a bevel
wheel G which is geared into another bevel wheel H, which is fixed permanently
onto the spindle I, which runs down the front of the instrument or stand, and
is fitted into the frame J, which is placed at an angle of some 10° or 15° degrees
from the vertical, as shewn in Fig. 2. On the spindle I we fit several arms or
wings K of a suitable number to turn over all the leaves of a piece of music,
these arms or wings K, are fitted on to the spindle I, by means of collars L,
which turn freely on the spindle I. Over these arms or wings we attach to the
spindle I, a lever M which is a fixture and turns with the spindle; on this
lever M we pivot a drop catch N which is arranged to catch the arms or wings K,
so that on the lever being turned over from right to left it carries one of the
wings with it, and on being released, swings back again, and picks up the next
wing, and so on. So as to keep the wings K at a suitable distance from each
other, to allow the drop catch N, to fall between them, we fix buttons or stops
as shewn at O. At the back of the frame J, we place a sliding ratchet bar P,
as shewn in elevation in Fig. 4 and in plan in Fig. 5, on an enlarged scale, at
one end of this ratchet bar, we attach projections as shewn at Q, these projections
are so arranged as to stop the lever M at the right distance so that the drop
catch N, picks up each of the wings K, in their right turn, this is effected by the
pawl R, which is pivoted on to the collar S, fixed to the spindle I and turning
with it. Therefore when the spindle I is turned round, the pawl R engages one
of the teeth T on ratchet bar P, moving it along from left to right the projec-
tions Q at the end thus being moved to their right positions.
On each of the wings K we place a thin rod U which is pivoted at the top
to a collar which slides along the wings K, these thin rods U are intended to
be placed between the leaves of the music to be turned. We attach a music rest V
to the frame J so as to be easily taken on or off at will.
The way in which our invention works is as follows. The wings K, having
all been turned over to the right side, and the ratchet bar P having been slided
along to the left the thin rods U, are then placed, one behind each leaf of the
music, to be turned, then on the lever A being pressed with the foot, the rod C
is raised, which moving the quadrant D, geared into the cog wheel E, turns the
spindle F and the bevel wheel G, geared into the bevel wheel H, turning the
spindle I, and the lever M with it: the drop catch N brings over the first wing,

page_text: and one leaf of the music, at the same time the pawl R engaging one of the
teeth T, moves the ratchet bar a little to the right. On the lever A being released
the rod C drops down again either by means of a counterbalance weight W or
a spring as shewn dotted at X the action is thus reversed the lever M moving
back again, the drop catch N picks up the next wing ready for the next operation.
As it sometimes happens that it is necessary to turn back quickly a page of
music, we effect this in the following manner, at the end of the lever M we
make a socket into which we can drop a rod or pin Y as shewn dotted in Fig. One,
this rod or pin, is dropped in front of the sheet of music required to be turned
back again.
Our drawing shews three wings two of which have been turned over the third
being in position, for the next operation. In Fig. 3 of our drawing we show
the three wings on the right side two being dotted at K¹.
The whole apparatus except the lever A is shown supported from the back
of a musical instrument, by means of a frame Z.
We wish it to be distinctly understood that we do not confine ourselves to the
exact details, shown in the drawings.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
1st. The arrangement of spindles, levers & wheels, as shewn in our drawings
by which we can turn over leaves of music, without the use of the hands or
the assistance of a second person.
2nd. The general arrangement as shewn in our sheet of drawings accom-
panying this specification.
