I GEORGE BROCKELBANK of 27 Beverley Road South Penge Park Anerley in the
County of Surrey, Gentleman do hereby declare the nature of my Invention for
IMPROVEMENTS IN APPARATUS FOR TURNING OVER THE LEAVES OF MUSIC to be as:
follows:-
1. .J 1.
The improvements in apparatus for turning over the leaves of music consist in a
means by which the repeats are automatically accomplished by the foot To effect
this I place a pulley or barrel on the centre column or axle of a music Turner with
an arm. extending longitudinally, a convenient, distance from the centre where
I place an adjustable elbow so as to come in contact with as many arms or means
for turning the leaves required by the work-To a pin or makefast on the pulley
or barrel I fix a cord wire or catgut which I pass round the said pulley or barrel
and through any holes or round leading pullies requisite to bring the cord down to
thee knee or foot At a suitable point of this cord wire or catgut I attach another
cord connected with any means of adjustment of any arms or other means used for
turning over the said leaves with a spiral spring or elastic india rubber cord if
necessary which yeilds after the adjustment is complete This cord may be
dispensed with in the event of there being no special adjustment to be acted
upon-With some Turners a spring acting upon the pulley or barrel may be found
necessary After adjusting the elbow on the arm according to the repeat in the
musical work, directly the foot or knee acts upon the cord the required leaves are
turned back to the starting point ready to be read over again.

page_text: I GEORGE BROCKELBANK of 27 Beverley Road South Penge Park Anerley in the
County of Surrey Gentleman 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 said improvements consist in a means by which the repeats in music are
accomplished by the feet acting on pedals fixed to a music stand leg or Piano Forte
pedal frame or other convenient place connected by a cord with a pulley or narrow
barrel (as shewn in Figures 1 & 2 letter a) placed on a centre column or axle
(e figures 1 & 2) of a music Turner with an arm (bb figures 1 & 2) extending
horizontally a convenient distance from the centre. At the end of this arm is a
moveable elbow (c figures 1 2 & 3) long enough to effect the repeat of the whole of
the music turning arrangement if required. In a hole in the said arm (d Figure 2)
I fix cord, pass it round the pulley or narrow barrel and through a hole in the
Turner case (if any) over a roller (k figures 1 & 3) and connect it to the pedal near
the floor (see capital D figure 3) by the cord n n and so soon as the foot presses
down the pedal arm (m Figure 3) the pulley arm and elbow forces back the
arrangements by which the music leaves have been turned, to the starting point-
to be again played and turned-At a suitable point of the cord (n n figure three)
I attach another cord and connect it with any means of adjustment of arms or
other means used for turning over the leaves of music, with spiral or other
springs &c that may be necessary to suit the Turner of any patentee.
In order to repeat any special page or pages in any part of the piece of music
I attach to the moveable elbow a spring (f figures 1 & 2) one end of which is
fixed to the arm the other passing through a hole in the bend of the said elbow,
(see o figures 1, 2 & 3) On this end of the spring I fix a cord (see g g figures 1
& 3) which passes through eyes or round rollers (see h h figures 1 & 3) extending
down to the pedal arm (C Figure 3) fixed to a slide (A. Figure 3) working on a
square rod on top of pedal (D-Figure 3) When the pedal arm (C Figure 3) is
pressed by the foot the elbow (c figures 2 & 3) is brought into a horizontal position
enabling the performer (by pressing his other foot on the pedal (m Figure 3) and
allowing the force of that foot to raise the pedal (C Figure 3) and with it the foot,
about one inch,) to place the said elbow before any unturned leaf he may desire to
repeat, by taking his foot off the pedal C which allows the elbow to be forced into
a vertical position by the spring (f figures 1 & 2-The spring (F Figure 3) I adopt
to prevent an over strain on the eyes (h h Figures 1 & 3).

page_text: 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,
'
First. The mode and means by which I effect the repeat as described and
illustrated with reference to the accompanying drawings.
Second. The arm (6 6 Figures 1, 2 & 3) the moveable elbow as described
(cc Figures 1, 2 & 3) and the spring. (f Figures 1 & 2) as and for the purposes set
forth.
Thirdly. The general arrangement and combination of parts forming my appa->
ratus or appliances for turning back or repeating the leaves of music.
