PROVISIONAL SPECIFICATION.
Improvements in Means for Turning Over the Leaves of Music
Books, or for like purposes.
I, EDWARD ARTHUR BROWN of 15, Holker Street, Keighley in the County of
York, Banker's Clerk, do hereby declare the nature of this invention to be as
follows, that is to say :-
It relates to improvements in means for turning over the leaves of music books,
or for like purposes and consists of forming or constructing said means so that
same shall be inexpensive as to cost of production and yet shall perform the
functions desired in an efficient manner.
The object of this invention is attained by the employment of an oscillatory or
partly rotating arm carrying at its outer end a receptacle (constructed as herein-
after described) in which is placed an adhesive substance (preferably compounded
as is the substance used by artists for erasing chalk from drawing paper) such
oscillatory arm being mounted by its other end upon a shaft arranged to extend
above or beyond the upper outer edge of the book or sheets of music when placed
upon their usual stand or support. The lower end of this shaft being coupled by
lever, wheel, cam or other suitable mechanism to a hinged finger-bar which is, as
also are the oscillatory arm and the above described shaft at all times when free
brought into a normal position by spring or like mechanism, such normal position
being that wherein the arm rests upon the leaf of the book or music about to be
turned over.
By the employment of the above mechanism, on pressing, deflecting or otherwise
operating the finger-bar so as to cause the oscillatory arm to be brought from its
normal position the leaf of the book or music adhering to the adhesive substance
is also moved by this oscillatory arm and is thereby brought or turned over while
by such book being mounted on the stand in such position that the centre of
oscillation of its leaves out of centre with or not in the same straight line as the
shaft on which the oscillatory arm is mounted said leaf by its own resilience
detaches itself from said adhesive substance, so that the oscillatory arm is forced to
return to its normal position without it.
Hinged or other retaining pieces operated by the finger-bar may be arranged to
hold the leaves in the position desired.
The above mentioned receptacle for holding the adhesive substance is arranged
to have an annular piece of metal surrounding but not in contact with the adhesive
substance; to this piece projections are attached to reach through said receptacle
in order that same may be operated by a spring mounted on the opposite side
thereof in such a manner that said annular piece when in its normal position allows
the adhesive substance to project slightly beyond it to be in contact with the paper,
while when the arm carrying this receptacle is oscillated or turned to the position
where it is desired that the leaf should be detached therefrom, provided the
resilience of this leaf is not sufficiently strong to effect this, then by the projections.
on the annular piece coming in contact with a stationary object the desired result
is effectually obtained.

!, EDWARD ARTHUR BROWN of 15 Holker Street, Keighley in the County of
York, Banker's Clerk 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, that is to say :-
It relates to improvements in means for turning over the leaves of music books,
or for like purposes and consists of forming or constructing said means so that
same shall be inexpensive, as to cost of production, and yet shall perform the
functions desired in an efficient manner.
Hereunto appended is a sheet of drawings illustrative of my invention, and to
these drawings reference is made in the following description.
Figs. 1 and 2 are respectively front and sectional side views of mechanism made
in accordance with my invention.
Fig. 3 is end elevation showing the part for contact with the leaves to be turned
over.
Fig. 4 is sectional view, as seen from above, of certain of the motor parts
hereinafter explained.
Figs. 5 and 6 are drawings in detail (to an enlarged scale) illustrating a method
of making the parts adjustable.
The object of this invention is attained by the employment of an oscillatory or
partly rotating arm a carrying at its outer end a receptacle 6 (constructed as
hereinafter described) in which is placed an adhesive substance c (preferably
compounded as is the substance used by artists for erasing chalk from drawing
paper) such arm a being mounted upon a shaft d arranged to extend above or
beyond the upper outer edge of the book or sheets of music when these are placed
upon the stand or support f. The arin a and the shaft d being made by one part
b
sliding within the other, as shown by Figs. 5 and 6, so that the receptacle 6 may
be raised or lowered or moved nearer to or farther from the shaft d, while the
screws gh secure them in any of their several positions.
On the lower end of the shaft d is fixed the wheel k in order that a segment
rack m fixed to the finger-bar may gear with it. This bar n is mounted on lever
arms oo pivotted at p, and to these arms o o¹ are coupled the arms r r by means
of the connecting rods ss. Mounted on the shaft d is the spring t one end of it
being fixed to the stand while the other end is attached to said shaft d in order
that it may, when free, bring said shaft d and its arm a into the normal position
shown by Fig. 1, in which position the receptacle & presses or presents the adhesive
substance c which it contains against the leaf of the book or music about to be
turned over.
By pressing upon the finger-bar n to cause it to move into the position shown
by broken lines Fig. 2 the rack m will have moved the shaft d and consequently
the arm a and the receptacle b into the position shown by Fig. 1 and as the adhesive
substance will have at such time adhered to and so brought with it the leaf of the
book to be turned, on said finger-bar being relieved of the pressure that brought it
down, the spring t will by its resilience reverse the movements of all of the parts,
consequently the lever arms rr (which had on the descending of the bar n also
descended) will rise, thus the one at r will prevent said turned over leaf from
following the movements of the receptacle 6 from which, on reaching its proper
position, it (said leaf) had become detached by the means hereinafter described.
To detach the adhesive substance from the leaf to which it had adhered on
said leaf being turned over or moved into its desired position, the receptacle, bis
.

page_text: made as shown by Fig. 3 to hold said substance c while a flat spring w is attached
to the arm a and made to extend over the substance c this latter protruding
through an opening a formed in same on it being pressed against the leaf to which
it has to adhere. The outer end y of the spring w is bent to extend beyond the
back part of the receptacle b so that when this is moved into the position shown in
broken lines Fig. 1 its said end y will come into contact with the part 1 of the
stand or frame f and so the spring w will be moved to force the leaf from adhering
to the substance c.
The parts and 2 are preferably of indiarubber in order to form a suitable
yielding surface to assist the actions of the arm a.
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 combination in mechanism for turning over the leaves of books of a lever
arm carrying a receptacle, means for operating said arm, and an adhesive substance
to be carried by said receptacle substantially as and for the purposes specified.
2. In means for turning over the leaves of music the combination of an adhesive
substance, a receptacle for said adhesive substance, means for bringing said
adhesive substance into contact with the leaf to be turned, and the device for
detaching same from said leaf substantially as herein set forth and described.
3. The combination and arrangement of the several parts forming the mechanism
for turning over leaves of books substantially as herein specified.
Dated this 21st day of June 1895.
