PROVISIONAL SPECIFICATION.
An Improved Leaf Turner for Music and the like.
I HERBERT LACY HOLDERNESS, of 3 Seaton Street, Fountain Road Hull, in
the County of York Wood Turner do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to construct an apparatus which shall auto-
matically turn over the leaves of the music or the like at the will of the operator.
I employ an ordinary wood board, or a flat plate of any suitable metal or
material, near the bottom of which I fix a piece of metal or the like for the music
to rest upon; the board or plate has a recess at the top, and in this recess I fix a
spindle or long metal pin, by any suitable means. I employ any number of levers,
which slide on to this spindle, and are used for turning the leaves over, these levers
have bent split ends with screws attached, these split ends being to receive one page
each of the music. The other end of the lever is enlarged, and has a vertical hole
through it for sliding on to the spindle, and at the back of the enlarged end is
affixed a flat plate with eyelets attached to it. I also employ two pieces of metal
with a spring and screw attached, fastened to the board, for holding the outer
sheets of music down to the board or plate.
At the bottom of the board on the right hand side in front I employ four or any
suitable number of keys connected to the same number of slides working in sockets
at the back of the board; the slides have eyelets at the top to which is fastened a
piece of band or the like, which passes up the back of the board, through eyelets,
to an eyelet attached to the plate at the back of the enlarged part of each lever;
and on the left hand side of the board, I employ the same number of keys, which
are attached to slides and eyelets in the same manner.
The action is as follows:-The outer or back sheets of music are held down by
the spring holders attached to the board, and each leaf of music is slid into the
slit the bent levers, one lever for each each leaf, and the screw turned to hold them
tight, the board rests on the ordinary music rest attached to the piano, and when
the pianist wishes to turn over the first leaf, he gives the first key on the right
band side of the board a slight press with the finger, this pushes the key and its.
corresponding slide down, the band connected to the slide having its other end
fastened to the eyelet farthest from it on the plate at the back of the first lever,
turns the lever and at the same time draws up the first key and slide on the left
hand side of the board, the other levers being turned in like manner, and if
wanting to turn the leaf back to repeat, the first left hand key is pressed down ;
when one key is pressed down its corresponding key and slide at the other side of
the board is up.
This apparatus can be made in any suitable metal or material and with as many
levers, keys and slides as required.

the County of York, Wood Turner, do hereby declare the nature of this invention,

ascertained in and by the following statement :---

DESCRIPTION OF DRAWINGS.
Fig. 1. shews front view of leaf turner for turning the leaves of music or
the like.
Fig. 2. shews back of same with leafholders half turned, and full plate attached
to same showing.
Fig. 3. is a front view of leafholder or lever.
Fig. 4. shews back of music stand with my improvements applied.
Fig. 5. shews side view of bottom part of music stand with method of operating
foot levers.
I employ an ordinary wood board or flat plate of any suitable metal or
material A, near the bottom of which I fix a piece of metal or the like B, for the
music to rest upon the board or plate has a piece cut out at the top, and in the
recess caused by cutting the material away I fix a spindle or long metal pin C. by
any suitable means. I employ any number of levers D. which slide on to this spindle
and are used for the purpose of turning the leaves over. These levers have bent
split ends with screws attached, these split ends being to receive one page each of
the music. The other end of the lever is enlarged and has a vertical hole through
it for sliding on to the spindle, and at the back of the enlarged end is affixed a flat
plate E with eyelets attached to it.
I also employ two pieces of metal F, with a spring and screw attached, fastened
to the board, for holding the outer sheets of music down to the board or plate.
At the bottom of the board at the right hand side in front I employ four or any
suitable number of keys G. connected to the same number of slides H. working in
sockets J at the back of the board, the slides have eyelets at the top to which is
fastened a band or cord K. which passes up the back of the board through eyelets
or over pulleys to an eyelet or hole attached to the plate E at the back of the
enlarged part of each lever, and on the left hand side of the board I employ
the same number of keys which are attached to similar slides and eyelets in the
same manner.
For upright music stands generally used by violinists and the like, Fig. 4, I
employ the same levers D as those shown in Fig. 1, band or the like being
attached in similar manner, runs down the back of the upright A' of the stand
through eyelets or suitable guides to foot levers L. working in slots L¹ and
pivotted at M. Fig. 5, where they are attached preferably to the end of the lever.
When the leaves are arranged for being turned over, the foot levers at the right
hand side of the stand are higher at the back than at the front, and project in front
beyond the pivotted part, the toe is placed under the front of the lever and with a
slight pressure the lever works on its pivot M. and lies flat on the face of the
bottom of the stand drawing the band or the like with it, by this means operating
the leaf turner or bent lever, so turning the leaf over.
Attached to the rest B, I employ a slotted plate B for the purpose of highering
or lowering the rest B to suit the size of the music being played.
The back of both the board and the upright music stand may be covered to hide
the mechanism and the whole may be ornamented in suitable manner.

page_text: I may employ a fastener or screw with the head cut away underneath at an
angle, as shown at D₁ Fig. 3. for the purpose of immediately tightening the split
heads of the leaf turners or holders.
The action is as follows:-The outer or back sheets of music are held down by
the spring holders F. attached to the board, and each leaf of music is slid into the
slit in the bent levers D. one lever for each leaf, and the screw D¹ turned to hold
them tight, the board A. rests on the ordinary music rest attached to the piano, and
when the pianist wishes to turn over the first leaf, he gives the first key G. on the
right hand side of the board a slight press with the finger, this pushes the key G.
and its corresponding slide H. down, the band K connected to the slide H. having
its other end fastened to the eyelet or hole farthest from it on the plate E. at the
back of the first lever D, turns the lever and at the same time draws up the first
key and slide on the left hand side of the board, the other lovers being turned
in like manner, and if wanting to turn the leaf back, to repeat, the left hand key is
pressed down; when one key is pressed down its corresponding key and slide at.
the other side of the board is up.
This apparatus can be made in any suitable metal or material, and with as many
levers, keys and slides as required.
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 :-
1. Leaf turners for music or the like, consisting of a board A, rest B, spindle C,.
levers D and F, keys G, slides H connecting link band or cord K and pin D',
operated in the manner and for the purposes substantially such as shown and
described.
2. The construction and arrangement of leaf turner applied to upright stands in.
the manner such as shown and described.
