Improvements in Apparatus for Turning Over the Leaves of Music
and the like.
I WILLIAM JOSEPH PITT, of 9, Avenue Road, Weymouth, in the County
of Dorset, Captain, 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 :-
This invention relates to improvements in apparatus for turning over the leaves
of music and the like and refers particularly to such apparatus as I have described
in my Specification of Letters Patent No. 25,112, of the year 1894.
To facilitate the manipulation of the apparatus and to render the movement of
the music turning arm or lever lighter and easier than in my earlier arrangement of
the same I now pivot to the side of the music turning arın or lever a separate
suitably shaped piece which is acted upon by the wedge or catch formed upon the
free end of the actuating bracket or lever, instead of as in accordance with my prior
Patent Specification aforesaid, the wedge or catch taking directly upon the music
turning arm.
Again in lieu of forming the small pivotted lever carried upon the free end of
the actuating bracket or arm as described in said Specification of Letters Patent
aforesaid with its end turned up vertically I have the end of horizontal limb or
portion of said pivotted lever fitted into, a separate slotted or bifurcated vertical
piece. This will permit of the movement imparted to the vertical piece being
perfectly vertical or perpendicular, as well as simplify the operation of fitting.
Further in accordance with this my present invention I have an arrangement
whereby the music-turning mechanism is actuated by pedal mechanism. all as will
hereinafter be more fully described with reference to the accompanying drawings
upon which
Fig. 1 is a side elevational view of a music-turning arm or lever,
Fig. 2 a similar view of the additional piece to be pivotted to the music-turning
arm or lever aforesaid, and
Fig. 3 shews in side elevational view the arm with additional piece attached
thereto.
Fig. 4 is an end elevational view of the small pivotted lever aforesaid and the
separate vertical piece mentioned above in connection therewith.
Fig. 5 being a front elevational view of the same.
Fig. 6 is a side elevational view of the pedal mechanism and
Fig. 7 is a rear elevational view of the same.
In my Specification of Letters Patent No. 25112 of 1894 I have described a
music turning device consisting of a double frame placed in front of the piano, the
under or rear portion of which frame is capable of being clamped to the top of the
piano. To the bottom of the double frame is adjustably secured a plate through
which a spindle passes. Around this spindle is coiled a spring enclosed in a box.
Upon the upper part of the spindle are loosely mounted the turning arms and to the
lower part of said spindle below the spring is fixed a bent bracket or arm
corresponding to the arm in the drawings accompanying my present application,
which arm carries at its free end a plate upon which are formed bearings carrying
a pivotted bar corresponding to that marked in the drawings herewith, which bar

page_text: was made to turn up and pass through an opening in the plate. The turned up
part normally dropped below the level of the plate except when the curved end
(corresponding to f1 Fig. 4) passed under the plate when the turned-up end projects
above the surface of the plate. A wedge or catch was provided at free end of the
bent bracket or arm which engaged with one of the turning arms at a time when the
spindle before mentioned was turned or partially revolved, the action of the coiled
spring returning the bracket or arm so soon as released.
The following description will clearly define the improvements constituting my
present invention :-
In the drawings a a are the turning arms or levers mounted. loosely at al upon a
spindle which spindle is partially revolved as desired by hand or foot and carries
round the actuating bracket arm b before mentioned, the wedge or catch c arranged
at free end of said bracket or arm & carrying the turning arm a and with it the sheet
of music as said bracket or arm is partially revolved. When released the action of a
spring contained in a box d (Fig. 6) at bottom of apparatus returns the bracket or
arm into its normal position behind the next turning arm a: Now in accordance
with this my present invention I pivot the piece e to the turner or arm a and it is
against this piece e that I prefer the wedge or catch c to take..
:.
And in order to obtain a perfectly vertical movement to the front end of the
small pivotted leverf carried at end of actuating bracket or arm I prefer to form
same as shewn in Figs. 4 and 5. In lieu as heretofore of making a turned up.
portion at front end of lever f: I have a separate vertical piece 9.into a slot or
bifurcation formed; in which the front end of the horizontal portion of the lever f
is fitted. As the bracket bis revolved and the end of the lever f is brought
clear of the plate h, the front end of lever f and with it the vertical piece 9 is
depressed sufficiently to allow the music-turning arm a to pass over same. Then as
the spring in box d returns the bracket or arm b to its normal position, the end f¹ of
the lever passes under the plate h and the end g is raised through aperture formed
in bracket and stands in front of the sheet of music held by turning arm a.
To effect the partial rotation of the spindle carrying the actuating bracket or
arm by a pedal. action I have upon said spindle first a pulley i (see Fig. 6) to
which, one end of a cord, wire or chain k is attached.
This wire cord or chain k is then taken around another pulley provided, from
whence it passes upwards over a pulley m at or near the top of the music holder or
stand. It then passes through the face of the piano through a suitable aperture
provided, and over another pulley n situated inside piano and thence down to the
lower pulley o to which it is attached..
Formed in one with the lower pulley o is a smaller wheel or pulley p to which is
attached the chain cord or wire g fastened at other end to the pedal r. All in such
manner that as the pedal is depressed the small wheel p is partially revolved and
with it the larger wheel o to which is attached the end of the actuating cord or
chain k as aforesaid.
According to the relative sizes of the small wheel p and larger wheel o, so will
be the proportionate amount of travel given to the music-turner actuating chain or
cord k.
Hence with a slight depression of the pedal and a consequent partial revolution
of the small wheel pa travel of say half an inch may conveniently be given to pedal
chain 7, and an inch and a half stroke or travel imparted to turner chain k, or any
other proportion or ratio desired may be effected or attained.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1. declare that what I
claim is:-
i
1. The improvement in apparatus for turning over the leaves music and the
like substantially as herein before described and shewn.
2. In apparatus for turning over the leaves of music and the like the combination
with the turner or arm a of the piece e pivotted thereto and which is acted upon,

page_text: lieu of the arm itself, by the driving wedge or catch upon the actuating bracket or
arm b, substantially as shewn and described.
3. In apparatus for turning over the leaves of music and the like, the construc-
tion and arrangement of vertical end g in connection with pivotted lever f carried
at free end of the actuating bracket b substantially as shewn and described.
4. In apparatus for turning over the leaves of music and the like the pedal
mechanism and arrangement of pulleys, wheels and cords chains or wires in
connection therewith, all constructed, substantially as hereinbefore described and
shewn.
Dated this 4th day of April 1895.
