DE BUITIVATION.
An Improved Apparatus for Turning over the Pages of Music.
I, GIUSEPPE EREDE, of Via Assarotti 18, Genoa, in the Kingdom of Italy, Civil
Engineer, 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 is designed to effect the turning over of the pages of music books
and the like, and consists of a folding frame with levers and cords forming a
portable apparatus suitable for attaching to pianos or organs or of being used on a
stand or desk. It is preferably made of thin metal with or without a wooden
-base.
I will now describe the apparatus with reference to the accompanying drawings
in which :-
:-
Fig. 1 shows a front elevation of the leaf turner.
Fig. 2 shows a sectional clevation of the lower end of one of the back supports
showing the cords and weights.
Fig. 3 shows a plan view of the cage e and one of the turnover levers, and also
shows the pawl e5 for actuating the toothed rack d.
Fig. 4 shows a perspective view of the cage e² and the turnover levers e.
Fig. 5 shows an end view of the lower part of the leaf turner as seen from the
left of Fig. 1.
Fig. 6 shows a similar view as seen from the right of Fig. 1.
Fig. 7 shows the invention as applied to a music stand.
a is the foundation of the leaf turner to the back of which are attached one or
more back supports 6 which slope upward and are connected together at their
upper ends in conical or pyramid form and are attached in any suitable way. The
lower ends of the supports b, are attached to the foundation preferably in such a
way as to allow of the apparatus being quickly and easily folded up.
With the
same object in view, the supports are further strengthened by a central upright c
made to extend and contract in telescope fashion.
An elastic strip c¹ is fastened between the foundation and the upright c towards
its upper end to hold the sheets of music or book in place.
On the foundation a is disposed a toothed rack which is caused to move hori-
zontally by the performer pressing with his foot a pedal y which may be one of the
pedals of a piano or other instrument and this movement is transmitted by a cord or
string e¹ to a pawl e³ which engages the teeth of the rack d. The pawl e5 which is
kept in place and guided by the cover plate et is preferably slotted as shown, and
after the pawl is pulled to the right to operate the rack and the pressure is released it
is drawn back by a suitable spring e which may be a small elastic cord as
shown.
The toothed rack is provided with two sets of teeth one at each end, meeting
near the centre of the rack. One set is made step-fashion and serves to
actuate the turnover levers e consecutively by means of the teeth d³, and ² is the
other set which engages with the pawl e2 by which the rack is actuated.
turnover levers e are fulcrummed on a common fulcrum gl, and are kept separate
from each other in a cage e² arranged in front of the foundation a at or near its
The

page_text: centre. The inner end of each of the levers e is formed with a spur e³ which will
engage one of the teeth 3 of the set when the rack is actuated."
The leaves are turned over in the following way. In each of the supports bare
a suitable number of cords and weights (see Fig. 2) and are separated from each
other in separate tubes by the supports being corrugated. The end of each cord is 5
provided with a ball or button 62. The cords are pulled out from the supports and
are carried down between the leaves of the music or of a book and each is attached
to the hooked end of one of the turnover levers e. As the rack is moved laterally
by the pawl e the movement will cause each lever e in turn to swing round and
turn over the leaf in doing so by means of the cord.
The cage may be attached to the foundation piece a in any suitable way.
The whole device may be attached to any existing piano or other instrument in
any preferred manner as for instance by spring clips (not shown), and may be
steadied or connected by elastic strips and hooks f.
It is so constructed as to fold into small compass and be readily carried in a
music case or enclosed within the cover of a piano.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The appliance or apparatus for turning over the pages of music books and the
like, as herein described and set forth.
2. In an appliance for turning pages of music books and the like the cords and
weights 6 levers e with spurs e³ and toothed rack operating as herein described
and set forth.
3. In an appliance for turning pages of music books and the like the combination
of the pedal action g, e¹, pawl e5, toothed rack d, levers e, with spurs e³, cage e²,
cords and weights b¹, tubular folding supports 6 central support c and base a, as
herein described and set forth.
