An Improved Apparatus for Turning over the Leaves of Music and
other Bound, Folded, Stitched, or Separate Leaves, and other
Analogous Objects.
I PETER MOAINSH of 17 Tudor Street, Coppice, Oldham, in the County of
Lancaster, Coach Body Maker, do hereby declare the nature of this Invention to be
as follows:-
My said Invention relates to improved means for turning over leaves and is chiefly
applicable to turning over the leaves of music when in position before the performer.
My apparatus may either be made part of the usual music support of a piano,
organ or other instrument or it may be made separate and placed on the said
support. It consists of a flat ledge to support the score, the said ledge being
recessed to contain a number of arms or fingers each of which holds and governs a
leaf. The recess is or may be covered by a plate. The said fingers are all pivotted
upon a common central stud in the recessed ledge and each finger is governed by a
spring which tends to wheel the finger round upon the pivot from right to left that
being the direction in which the leaves are turned over. The said springs may be
arranged in several manners but I at present use flat springs which are secured to
and partly coiled round'the aforesaid central pivot the free ends or tails of the
springs being secured to the respective fingers. On the right hand side of the ledge
I arrange a double catch operated by a presser-plate or trigger or knob in such a manner
that when all or any of the fingers have been placed in the custody of the catch, they
are released one at a time by touching the presser-plate or trigger or knob when it is
desired to turn over a leaf. By touching the said presser-plate or other means one
member of the double catch is withdrawn from before the first finger allowing the
spring to wheel it round and thus turn over the leaf. But at the same time to
prevent more than one going round, the other member of the catch rises in front of
the next succeeding finger and holds it until the first member of the catch has
returned to its normal position whereupon the second member of the catch again
Binks out of the way. By this arrangement one leaf only at a time can be turned over.
The invention is applicable not only in conjunction with a musical instru-
ment such as a piano, organ, harmonium or the like but can also be fitted to or fixed
upon a music stand, conductors desk, reacing stand, photo or print case or in other
situations where it is desirable to turn over leaves or the like expeditiously and
without using the fingers. In the case of a music stand or the like the means for
releasing the double catch and so turning the leaves might be operated from the foot
of the performer.

COMPLETE SPECIFICATION.
An Improved Apparatus for Turning over the Leaves of Music and
other Bound, Folded, Stitched, or Separate Leaves, and other
Analogous Objects.
I, PETER MAINSH, of 17, Tudor Street, Oldham, in the County of Lancaster,
Coach-body maker, 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 said invention relates to improved means for turning over leaves and is chiefly

page_text: applicable for turning over the leaves of music when in position before the performer.
My apparatus may either be made part of the usual music support of a piano,
organ, or other instrument or it, may be made separate and placed on the said
support.
And in order that my invention may be more fully understood, I have caused to be
appended here unto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. 1 is a front view, Fig. 2 a plan and Fig. 3 a side view of the apparatus
complete. Fig. 4 is a plan with the top of the ledge removed. Figs. 5 & 6 are,
respectively, a detached front view and plan showing the mechanism by which the
arm or fingers are retained and released, and Figs. 7 & 8 show the pivot end of the
latter on an enlarged scale.
In carrying out my invention, the apparatus consists of a flat ledge a, to support
the score b, the said ledge a being formed with a recess c to contain a number of
arms or fingers d, each of which holds and governs a leaf. The said arms or fingers d
are all pivoted on a common central stud e in the recess c of the ledge a and each
arm or finger d is governed by a spring f, which tends to wheel the arm or
finger d round upon the pivot e from right to left, that being the direction in which
the leaves are turned over. The said spring may be arranged in several manners,
but I preferably use wire springs f, which are each placed on and partly coiled round
studs, so as to permit of being readily replaced when necessary, the free ends or
tails of the said springs f being secured to or bearing against the respective arms or
fingers d. On the right hand side of the ledge a, I arrange a double catch g, g
governed by springs h, h' and operated by a presser plate i, trigger or knob, in such a
manner, that when all or any of the arms or fingers d have been placed in custody
of the double catch g, gl, they are released one at a time by depressing and thereby
bringing the pressure plate i, trigger or knob, into the position shown in dotted lines
Figs. 5 & 6, when it is desired to turn over a leaf, the spring h, bringing the
. double catch g, g¹ back to its normal position. The member g¹ of the double
catch g, g¹ is fixed on a spinale k mounted in the ledge a and furnished with the
presser plate i, trigger or knob, the member g being arranged in contact with and to
slide horizontally in front of the member g¹. On depressing the said presser plate i,
trigger or knob, and thereby partially rotating the spindle k, both members of the
double catch g, g₁ are simultaneously operated, the member 9 withdrawing from
before the first finger or arm d, allowing the spring f to wheel it round and thus
turn over the leaf; but at the same time to prevent more than one going round,
the other member g' rises in front of the next succeeding finger and holds it while
the first member has returned to its normal position, i.e. when the pressure is taken
off the presser plate i, trigger or knob, whereupon the second member g' again
sinks out of the way below the next arm or finger d. By this arrangement, one leaf
only at a time can be turned over.
The front of the ledge a I provide with a catch 1, which when raised serves to
retain the arms or fingers d, in the position as indicated by dotted lines in Fig. 4,
so as to permit a ready placing of the leaves into the free ends of the arms or
fingers d. The horizontal portion of the arm or finger d is flat, and the pivot end
thereof half twisted, see Figs. 7 & 8, so as to position the respective ends one on top
of the other on the same stud e, and the front ends thereof side by side, thus bringing
the same into a very small compass.
The vertical portion of the arm or finger d in front is furnished with a lip m, to
receive the leaf, and is pivoted to the free end of the horizontal portion thereof, so as
to permit of moving the same out of the way when desired.
The invention is applicable not only in conjunction with a musical instrument such as
a piano, organ, etc. or the like but can also be fitted to or fixed upon a music stand,
conductors desk, reading desk, photo or print case or in other situations where it is
desirable to turn over leaves or the like expeditiously and without using the fingers..
To facilitate the fixing of the apparatus the bottom of the ledge a is furnished with
_clips m¹ to grip the ledge n of the respective rest otherwise used.

page_text: In order to hold the score b firmly on the ledge a, I furnish the same with an
upright arm o, the top of which is formed with a small notch and the bottom with a
plate p having a slot p² and hole p² formed therein.
In conjunction with the said arm o I employ an elastic band q one end of which
is furnished with a hook gl to be placed into the said notch and the other end with a
button headed tube which when passed through the hole p³ and moved in the slot p¹
towards the arm o, holds the score b which is placed between the latter and the elastic
band 9, securely on the ledge a. If desirable the said arm o may be made
removable.
The ledge a is formed with a back a' which is furnished with fingers a³, so as to
further assist in retaining the score b on the ledge a.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim, is:
"In an apparatus for turning over the leaves of music and other bound, folded, stitched
or separate leaves and other analogous objects."
1st. The general combination and adaption of parts, operated substantially as and
for the purpose specified.
2nd. The employment of a double acting catch g, g¹ by means of which the arms
or fingers d are successively retained and released, substantially as and for the purpose
specified.
3rd. The formation of the pivot ends of the arms or fingers d, substantially as and
for the purpose specified.
4th. Governing each arm or finger d by means of a spring f, one end of which is
bearing against the same and the other end of which is coiled round a stud f¹,
substantially as and for the purpose specified.
the
5th. The employment of the catch 7 in front of the ledge a, substantially as and for
