Improved Means or Apparatus for Turning Over the Leaves of
Music Books and the like.
I WILLIAM LANCELOT BINSTEAD of 63 Lincolns Inn Fields in the City of London,
Solicitors Clerk, 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:-
My invention relates to improved means or apparatus for turning over the leaves
of music, books, and the like, and has for its object to provide a handy simple and
inexpensive apparatus which can be readily applied to the music rests of pianos and
organs of every. size and description and to the music rests of orchestra stands, or
for any other similar purposes. And in order that my invention may be more fully
understood, I have shewn the same in the accompanying drawings in which Fig. 1 is
a front view of my apparatus as applied to the music rest R of a piano for instance.
Fig. 2 is a plan, and Fig. 3 a rear view of the same apparatus. Figs. 4, 5 and 6, are
details. Fig. 7 is a modification of the releasing mechanism more particularly
applicable to pianos.
As shown in the drawing my improved apparatus, which may be made of metal,
wood, ebonite, or other suitable material, consists of a frame or bar a provided with a
descending projection b at the back of which are screwed a lower rectangular piece e
carrying a hollow split spindle and an upper rectangular piece e provided with
notches in which fit the projections g g' of the said spindle d. Upon this spindle
are mounted over one another a number of spring arms h of peculiar shape whose
outer extremities are twice bent over as clearly shewn in Fig. 1, and whose inner
extremities are circular and have a perforation by means of which they are passed
over the spindle d. These spring arins are arranged in such a manner as to fit over
one another and to occupy as small a space as possible when in a contiguous position.
As shewn in Fig. the circular inner extremities, and hinged part of the arins h are
hollow to receive a spiral spring ; one end of which is bent and engages in a hole
formed in the side of the circular extremity of the arm h, while its other end is
Near
likewise bent to enter the slot k of the spindle d (fig. 5) and be fixed therein.
the out end of the arms are rivetted alternately clips forming two adjacent rows
as seen in Figs. 1 and 3. These clips have for object to hold the music leaves Land
for this purpose are punched as shewn in Figs. 1 and 3. to form inward projections
or sharp edges designed to more thoroughly nip the said leaves.
The mechanism used for successively releasing the above described spring arms h
consists of a plate m bent at right angles and having its horizontal part m pivoted to
a flange formed at the lower part of the right hand end of the frame a which end has
the shape shewn separately in Fig. 4.
Upon the front part of this plate m is pivotted a piece o of peculiar shape provided
with a handle pa pin g and a finger r. The piece o can move to a certain extent
only such motion being determined by the pins which moves in a slot t formed in
the said piece n.
The rectangular plate m pivots as already stated upon the flange n and carries in
its motion the piece o, such motion being rendered necessary in order to bring back
all the spring arms within the guide u in order to fix the music leaves in the clips
previous to operating the apparatus. At the back of the right hand end of the
frame a is pivotted a finger entering a slot w in the plate m and controlled by a
spring z, this finger has for object to hold the plate m in position when the apparatus
is being used, and to release the same when the plate m is moved round for the
purpose above stated.
The handle is perforated as shewn at one end to enable a
cord to be attached thereto, whose other end would be fixed to a pedal actuated by the

page_text: foot of the performer. My improved apparatus is fixed to the lower ledge of the
music rest by means of the screw clips y y'. A central rod A whose lower end is
passed through the hollow spindle may be used for pianos to steady the music piece,
in case the latter was not bound. Or I may use a rod having a foot suitably fixed
upon the central part of my apparatus and provided at its upper end with a clip in
which is inserted and secured the unbound music book..

My improved apparatus having been fixed to the lower edge of the music rest R
by means of the screw clips y, y as shewn in Fig; 1, the spring finger e is raised
and the rectangular plate moved round so that the pin q assumes the position
shown in Fig. 4. The spring arms are now brought round within the guide w. and
the plate m turned back in its former position secured therein by the spring finger v.
while the pin rests now against the outer extremities of the spring arms das shewn
in Figs. 1 and 2. On pressing down the handle p''the pin moves to the right hand
side and release the foremost spring arm'd which solicited by the spiral spring j flies
back to the other side of the rest L, carrying the music leaf with it. At the same
time the finger advancing prevents the next arm springing back until the pin q
having been first brought back to its former position, is again moved to the right
hand side to release when convenient the next spring arm'd.

A modification of the releasing mechanism of my improved apparatus is illustrated
in Fig. 7 in which represents one end of the spring arms which in this, case are
only bent once at their outer extremities and are alternately of the same length but
'contiguously of different lengths as shewn.' 'A lever pivotted' at 'o' releases when
being pushed alternately one way or the other one of the spring armis d' and this
oscillating motion of the lever is limited by two pins pl; p², one of which the pin pl
is fixed to a spring blades secured at the back of the right hand end of the frame a
and having a sinall" finger piece f" which is 'depressed to allow the lever being
moved to the right hand side and out of the way of the arms d' when the same have
to be placed in position to receive, the music leaves.
