page_text: I, ALFRED MORLEY HAYWARD of 54 Malpas Road New Cross in the County of Kent
Electrician do hereby declare the nature of this invention to be as follows:-
The object of my invention is to produce a music leaf turner which shall be of
simple and efficient construction and very cheap to make. For this purpose most of
the parts are made of such a form or construction that they can be conveniently
stamped out of sheet metal. Upon an angular frame which may be made partly of
wood and partly of stamped metal, I provide at each end a clip for attaching it to the
music desk. Between the clips or about in the middle of the apparatus I connect
the arms or levers for turning the music leaves their fulcrum being in a box or casing
with a slot for the arms to pass through. The arms are stamped out of sheet metal
and curled up at the end for going round the fulcrum pin. To the fulcrum end of
each of the arms is attached a coiled spring the other end of which is attached to the
frame; these springs act to turn back the arms and therewith the music leaf. Or
the arms may be provided with blocks at their fulcrum end for the fulcrum pin to
pass through in which case the box or casing may be omitted. Each arm may have
a tag or lug to take hold of for turning it back. The clips for holding the music
leaves are stamped out and nipped round the arms. At the right hand of the
apparatus I provide a catch device for holding the arms and for releasing them one
by one. This catch device is a lever stamped out of sheet metal, hinged to the frame
and having a spring tooth or catch which comes over the arms. This lever when
pulled to release an arm draws a small pivotted stop over the next lower arm while
the uppermost arm is being released by the lever a spring bringing the stop back
against a fixed peg which also serves as a lateral guide for the arms. By suitable lever
and rod connection the aforesaid catch lever may be operated from the left hand
side also if desired.
The apparatus is provided with the usual centre rod for the music to turn on, and may
also have a spring clip for bearing upon the back of the book. In order to adapt the
apparatus to small instruments I may provide it with a rack or frame at the back.
Dated this Thirtieth day of January 1897.

page_text: same is to be performed to be particularly described and ascertained in and by the
following statement:―
The object of my invention is to produce a music leaf turner which shall be of
simple construction very efficient and capable of being made very cheaply. For this
purpose most of the parts are made of such a form or construction that they may be
conveniently stamped out of sheet metal.
Figure 1 of the accompanying sheet of drawings represents in elevation a music
leaf turner constructed according to my invention.
Figure 2 is a plan thereof.
Figure 3 is a detail view of a clip for attaching the apparatus to a music desk.
Figure 4 is a detail view of one of the guides or rests for the leaf turning levers
or arms.
Figure 5 represents in plan and elevation respectively part of one of the leaf
turning levers.
Figure 6 shews in end elevation and plan respectively the other guide or rest for
the leaf turning levers and
Figure 7 is end elevation and plan respectively of the catch device for holding the
leaf turning levers or arms.
The
Upon an angular frame A B C, Figures 1 and 2, which frame is suitably made of
stamped metal or partly of metal and partly of wood I provide at each end a clip F
see also Figure 3 for attaching it to the music desk of the musical instrument.
music is supported in the middle by the projecting part C and at the ends by the
parts B. Between these clips F or about in the middle of the apparatus I connect
the arms or levers e¹ e² e³ e (Figure 1, 2 and 5) for turning the music leaves, their
fulcra being on a hollow or solid pine (Figure 2) fixedly mounted above in the part C
of the frame and below in the part c¹, the tube-like washer c² being for the purpose
of preventing movement of the levers in their axial direction. Or instead of using a
pin e the fulcrum ends of the levers e¹ e² e³ e¹ may be in a box or casing with a slot
or slots sufficiently large for allowing of the desired motion of the said levers such
box or casing being attached to or made in one with the frame A B C. The levers are
preferably stamped out of sheet metal and curled up at one end t for going round the
fulcrum pin es see more particularly Figures 2 and 5. Or the levers may be provided
with blocks at their fulcrum ends for the fulcrum pin to pass through. To a hook or
loop wat the fulcrum end of each of the arms el e²ese is attached a helical spring
which coiled springs are called respectively d¹, d², d³, d₁ on the drawing. The other
end of each of these coiled springs is attached to the part A of the frame and the
said springs being in tension serve to turn back the arms and therewith the music
leaves. Each arm or lever may have a tag or extension e (Figures 1 and 2) of a
different length to take hold of when turning the said arms back by hand. The
clips D for holding the music leaves are constructed in any suitable manner but
preferably by being stamped out and nipped round or rivetted to the arms e¹ e³ ³ eª.
At or near the right hand end of the apparatus I provide a catch device H
(Figures 1, 2 and 7) for holding the arms and for releasing them one by one. This
catch device H consists of a lever stamped out of sheet metal, hinged to a bracket G
on the part A of the frame and having a pivotted tooth h normally held up by a
spring which tooth normally projects above the bottom of and in front of the
arms e e e e When this lever H is pulled down to release an arm, say e', it draws
down a small stop pivotted to a bracket P on the part A of the frame see
Figures 1 and 2 by coming into contact with same and carrying with it the lower arm
of said stop r and the upper arm of the stop passes down over and in front of the
next arm to hold it while the arm e' is being released and carried over by
the spring d to turn over a page. When the lever H is released the spring' brings the
pivotted stop r back to its normal position shown in Figure 1 and with it the lever H
is also consequently brought back so that its pivotted tooth h engages with or is in
front of the next arm e². The spring ¹ brings the stop r back and the latter is
provided with a peg or lug which projects into a curved slot a' in the part A of the
frame to limit the motion of the said stop. If desired however there may be a fixed

page_text: peg on the part A of the frame against which the stop r can take when in its normal
position. The brackets G figures 1 and 6 is provided with a slightly curved arm as
best seen on Figure 6 which serves as a guide or support to the ends of the
levers e e e e and there is a similar guide g attached to the other side of the apparatus
(see Figures 1 and 4) for the same purpose. The parts E which are suitably made
in one with the frame A B C serve as guides to prevent the levers e e e e from
rising above their proper position. By suitable lever and rod connection the
aforesaid catch lever H may be operated from the left hand side of the apparatus if
desired.
The apparatus is provided with the usual centre rod M which may be made
detachable and has an India rubber cord m suitably passing over the centre of the
pages of the music and through the hollow pin es. The other end of the cord m has
a button n which takes over the back of the support M and the latter is slotted at
the top to retain the cord as shewn in Figures 1 and 2.
In order to adapt the apparatus to small instruments I may provide it with a
music support, rack or frame at the back.
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:-
1. A music leaf turner consisting of frame on which is mounted a number of
levers or arms provided with clips D and actuated by springs d¹ d² d³ d', a hinged
spring catch engaging with one of the levers and a pivotted spring stop for engaging with
said hinged catch and the next lever substantially as described and shewn.
2. A music leaf turner consisting of a frame A B C centre rod M, elastic cord m
spring clips F, lever arms el e ese having clips D and springs d¹ d² d³ d¹ a
hinged catch H with a pivotted tooth h, and a pivotted spring stop r substantially
as described and shewn.
3. The construction of music leaf turner shewn on the drawing.
