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 declnie the nature of this invention to be as
follows:-
This invention relates to improvements in apparatus for turning over the leaves
of music and the like, and consists of a double flame of a convenient shape, the
under or rear portion of which is adapted to clamp upon the top of a pianoforte or
the like, the two parts having suitable springs superposed between them to keep
the upper part of the said double frame, pressed to the front so as to securely
hold the music copy, for instance, in conjunction with a vertical rod which passes
down in a groove or recess in the face of the upper part of such double frame.
To the bottom of the double frame aforesaid, is adjustably secured, preferably
by depending screw threaded rods upon which work nuts, a semi-circular plate
having segmental side projections at the ear thereof, though which plate passes a
spindle, the part of same which is below said plate, being enlarged in circumference
around which enlarged part is coiled a spring, oue end of such spring being secured
to the spindle while the other extremity is fixed to one of the supports which
connect and partly support from the before mentioned plate, two discs between
which 18 located the enlarged portion of the spindle around which the spring 18
coiled.
Upon the upper part of the spindle which is above the plate aforesaid, are
loosely mounted a number of arms or turners the undersides of which are notched
or cut-away.
To the lower part of the aforesaid spindle, below the coiled spring, is mounted a
bent bracket, carrying at its freo end a rectangular plate, the rear end of which is
bi-furcated, and turned down. Between such downwardly tuined bi-furcated ond
18 pivoted a bar which is turned up at the forward end, such upwardly turned end
passing through an opening in the said rectangular plate at the end of the bracket
and normally projecting above the surface of such plate, the pivotal point being
more to the rear than the front of such bent bar so that when the bracket is turned
to a certain position, the front end of such bar will drop down below the level of
the rectangular plate. The rear part of such bar is bent up above the level of the
pivot and then giveu a downward turn so that when the bracket carrying same 18
moved back by the action of the coiled spring, such raised end will be depressed by
contact with the segmental side projection upon tho somi-circular plate before
mentioned.
A catch provided with a vertically projecting shoulder, is fixed to, or formed
integral with, the free or outer end of the bracket, such catch being bevelled off at
the front and rear, the object of such catch being to engage one of the arms or
turners at a time.
The before mentioned vertical rod at the front of the frame 18 designed to engage
with the upper part of the spindle for the purpose of turning or partly rotating
sane to operate the mechanism, the upper end of such rod being provided with a
suitable handle. Rollers may or may not be provided upon the bottom of the

page_text: In lieu of actuating the apparatus by hand as before described, the spindle may
be connected by a cham or the like, with a suitable lever or pedal to enable the
apparatus to be worked by the foot.

Improvements in Apparatus for Turning Over the Leaves of music
and the like.
1 WILLIAM JOSEPH PITT, of 9 Avenue Road, Weymouth, m 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, which I will now proceed to describe with reference to the
accompanying drawings upon which, Fig. 1 represents in front elevational view, an
apparatus for turning over the leaves of music and the like, constructed in
accordance with this invention, and Fig 2 is an end elevational view of the same.
Similar letters of reference indicate like parts in each of the figuies.
The apparatus consists of a double frame a a¹ of a convenient shape and size, the
under or lear portion a¹ of which is adapted to be clamped as at a³ upon the top of
& piano or the like.
The two parts have suitable springs 6 superposed between them to keep the
upper or front part a of said double frame pressed to the front, so as to securely
hold the music copy, for instance, in conjunction with a vertical rod c which passes
down in a groove or recess d in the face of the front part a of such double frame
behind which the music is placed
e
To the bottom of the double frame a a¹ is adjustably secured, preferably by
depending screw-threaded rods f, a plate through which the spindle / passes.
Around this spindle (below the plate ) is coiled a spring.
This may, if
desired, be enclosed in box k attached to underside of plate g
Upon the upper part of the spindle and above the plate g are loosely mounted
a number of aims or tuiners and to the lower part of the aforesaid spindle h below
the coiled spring 1, is fixed a bent bracket m carrying at its fice end the rectangular
plate n. Benungs are formed at the rear end of the platon and therein 18
pivotted the bar or level o which 18 tuined up at the forward end o³, said turned up
portion of passing through an opening provided in said plate n.
The turned-up portion o' of the bar or lever o normally drops below the level of
the rectangular platen except when the curved end of the bar or lever o passes
under the plate g when the end o' projects above the surface of the plate n as seen
In the drawings.
A wedge or catch 7 19 provided at the fice or outer end of the bent bracket m.
This wedge 7 boing suitably shaped to permit of its engaging (when said bracket 18
tuined) with one of the arms or turners at a time. The partial evolution
necessary for turning over the sheet of music or the like may be given to the
spindle by action of the hand upon the milled head fitted at bottom end of
spindle, or a pulley such as many be fixed upon the spindle, and a chain or cord
lead therefiom through suitable guides, to a pedal to permit of the music being
turned over by a movement of the foot.
The action of the coiled spring returns the bent bracket or arm o immediately
it 18 leloased, when it takes up position roady for tuining the next sheet.

page_text: 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. The improvements in apparatus for tuning over the leaves of music and the
like, substantially as herembefore described, and shewn in the accompanying
drawings.
2. In apparatus for turning over the leaves of music and the like, the combina-
tion and arrangement of double frame a a¹ connected by springs b with the vertical
rod c passing down suitable groove d formed in the face of the front portion a of
the double frame aforesaid for the purpose of securely holding a sheet or book of
music and the like, substantially as shewn and described.
3. In apparatus foi tuining over the leaves of inusio and the like, the combination
with a coiled spring i mounted upon a spindle à, of the turning arins I mounted
loosely upon sanie spindle and the lever or arm m arranged with wedge or catch
and locking-bar or lover o at its free end, all operated by partially rotating the
spindle, substantially as herein before described and shewn
g
4. In apparatus for turning over the leaves of music and the like, the combination
and arrangement of the double frame a a', springs b, vertical rod c, groove or
recess in front part of frame a, bottom plate or book-rest e, connecting pins f,
plate g, spindle h, coiled spring i, arms ou turners, bracket m, plate n, bearings n',
pivotted bar or lever o with tuned-up end o¹ and curved end p, wedge or catch q
and suitable tunning media in connection with spindle, all constructed and
operating substantially as heiciubefore described and shewn
Dated thus 27th day of September 1893.
