IMPROVEMENTS IN APPARATUS FOR DISPENSING WITH THE NECESSITY OF TURNING OVER THE LEAVES OF PRINTED OR MANUSCRIPT MUSIC
Year: 1884

page_text: I, JOHN THOMAS KEY of 8 Machon Bank Sheffield in the County of York, Civil
Engineer, do hereby declare the nature of my said invention for IMPROVEMENTS IN
APPARATUS FOR DISPENSING WITH THE NECESSITY OF TURNING OVER THE LEAVES
OF PRINTED OR MANUSCRIPT MUSIC to be as follows:-
My Invention relates more particularly to Improvements in apparatus for
dispensing with the necessity and annoyance of turning over printed or manuscript
music, and it consists (broadly speaking) of an arrangement of mechanism, 6xed
upon a suitable frame, and connected with and operating a roller so that it will
wind up a long continuous strip, ribbon or sheet of music, from a second roller fixed
at a suitable distance from it, and placed in such a position that a performer may
easily read the music as the printed strip travels along, In carrying out my
invention I use long continuous strips or sheets of paper or other suitable material
(upon which the musical score is printed or written) coiled or rolled upon suitable
rollers. I attach to a light frame or stand, a simple clockwork movement operated
by a spring (as being most convenient) and upon one of the wheel axles made to
project for the purpose I fix a roller provided with a clip, or other suitable means
by which the end of a strip or sheet of music may be secured. A lever or catch
movement connected with the clockwork enables the performer to start or stop the
action of the apparatus at pleasure, and the speed of the travel may be regulated by
means of a break, or by the flyer, or by other device. The roller (which for
distinction I call a clipp roller) may also be thrown out of gear with the clockwork
so that it is free to revolve on its axis, At a suitable distance from the cliproller
I fix another apparatus consisting of a clockspring in connection with a train of
wheels and a projecting spindle upon which may be placed one of the loose rollers
with the music coiled or rolled upon it.
The loose end of the coiled strip is then connected to the clip roller by means
of the clip before described and tho clockwork being wound up the apparatus is
ready.

page_text: On moving the starting lever the strip of music is gradually drawn from the
loose roller and wound upon the clip roller, the music passing with regular speed
(which may however be varied at will) before the eye of the performer from the
commencement of the tune to its finish. The action of winding the music off the
musicroller winds up the beforementioned clockspring, so that when the cliproller is
thrown out of gear, the strip of music is rewound upon the music roller; which can
then be taken off the spindle, and replaced by another if desired.
The apparatus may be arranged to work either horizontally or vertically; if
vertically the music must be printed or written across the paper or other material,
instead of lengthwise.

I, JOHN THOMAS KEY of 8 Machon Bank Sheffield in the County of York, Civil
Engineer do hereby declare the nature of my invention for IMPROVEMENTS IN
APPARATUS FOR DISPENSING WITH THE NECESSITY OF TURNING OVER THE LEAVES
OF PRINTED OR MANUSCRIPT MUSIC and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, that is to say :-
My invention relates to improvements in apparatus for dispensing with the
necessity and annoyance of turning over the leaves of printed or manuscript music
and it consists broadly speaking of an arrangement of mechanism fixed upon a
suitable frame, and connected with and so operating a roller, that it will wind up a
continuous strip, ribbon or sheet of music, from a second roller fixed at a suitable
distance from it, and placed in such a position that a performer may easily read tho
music as it is drawn from one roller to the other.
In order that my invention may be clearly understood I annex a sheet of
drawings, in which the same letters of reference indicate the same parts in all the
figures.
Fig. 1, is an elevation of an apparatus for music, constructed according to my
invention.
Fig. 2, is an end view of the driving gear, or wind up mechanism.
Fig. 3, is the end view of the recoil mechanism for re-winding the coil.
Fig 4, is a plan of the apparatus.
In carrying out my invention I use continuous strips or sheets of paper or other
suitable material A, upon which music is printed or written, and I attach it by its
ends to a pair of rollers B, B¹,-I construct two pieces of mechanism, which consist
of a suitable train of wheels in connection with a spring.
The one marked C is the driving gear, and is wound up by a handle applied to
the bevil wheels D, or by a ratchet lever, or other means; the other marked E, is
the recoil mechanism which is wound up by the action of C, drawing the strip off
the roller B',
I prefer to fix the two parts C and E, upon a frame F, and at a convenient
distance apart, the frame being arranged so as to stand on a table, or to be fixed to
any musical instrument, by suitable attachments.
The Rollers are constructed to slip on to the projecting vertical axle of one of the
train of wheels, of each train, as clearly shown in the drawings Fig 1, 2. 3, by
which they are rotated alternately. Each piece of music may be permanently
attached to a pair of rollers, and kept in that manner for use; or the strips may be
secured to the rollers by spring Clips or other means, when required.
The roller B, may be drawn out of gear with the mechanism, by means of the
lever G, and the movement of C may be stopped or arrested by the catch H, acting
upon the flyer K,
I is a brake acting against a brakewheel or disc J, for the purpose of regulating
the travelling speed of the strip of music.
The action is as follows, the strip of music A is coiled upon the roller B¹, and the
other end attached to the roller B, which are then placed upon the axles as shown
in the drawings, The mechanism C is then wound up, and started by moving the
lever H. out of contact with the flyer K; the roller B, revolving, winds the strip
off the roller B¹, causing it to revolve, and with its train of wheels, to wind up the
spring L, oweing to the superior power of the wound up spring in mechanism˚C.

page_text: When the piece of music is completely wound off, or at any point where it is
desirable to commence again, it is simply necessary to move the stop lever H, and
throw the roller B out of gear, by means of the lever G, when the action of the
spring Land the mechanism E winds the strip upon the roller B¹.
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
1st The Apparatus for winding up and for unwinding a continuous strip or roll
of material upon which music, may be delineated, substantially as herein before
described and illustrated,
2nd An Apparatus for the purpose hereinbefore specified, consisting of two sets of
springs mechanism, in connection with two rollers, upon which a long strip of
suitable material may be wound, on either roller alternately, by the action of the
mechanism, substantially as herein described and illustrated.
