PROVISIONAL SPECIFICATION.
Improvements in Music or Book Holders.
ADOLPH JULIUS LEHMANN of 37 Kemlyn Road Liverpool in the County of
Lancaster Civil Engineer do hereby declare the nature of this invention to be as
follows:-
My invention consists in providing a music stand or music rack (such as used on
Pianos or Music stands in Orchestras &c.) with pins or pegs of novel construction to
hold the sheets of music back in their place after or before they are to be turned over.
These Pins or Pegs in my invention work or revolve automatically that is they allow
the sheets of Music as they are required to be turned over freely to pass and after the
sheet has passed the pins or pegs fall or revolve by counter weight or by springs or
an elastic force into their original places automatically. The Pins or Pegs are made
of a thin strong material in a loop or round or other form so as not to obscure any
printed matter on the sheets of music or leaves in books, they are weighted on the
bottom or actuated by spring or elastic force working on a pivot or on a rod in a
pipe inserted into the bottom part of the stand so as freely to turn to either side. The
pins or pegs are stationary or removable from one stand to another revolving pins or
pegs can be used for holding back leaves of other books than music. I also provide
in the centre or other convenient place of the music stand a strong upright wire
which holds the music from falling off or-removing when not required this wire is
actuated by a spring or elastic force to press on the sheets or books to keep them in
their place it also allows the wire to be pulled forward so as to allow space to receive
and hold music or books of different thicknesses.

COMPLETE SPECIFICATION.
Improvements in Music or Book Holders.
I ADOLPH JULIUS LEHMANN of 37 Kemlyn Road Liverpool, in the County of
Lancaster Civil Engineer 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 :-
My Invention has for its object to produce a device to be adapted to music stands
or racks to enable the leaves of the music, before or after having been turned, to be
retained and held in the desired position in a more efficient and simple manner than
heretofore.
In the accompanying drawing illustrative of my said Invention Figures 1 and. 2
represent side and front elevational views respectively of my device, referring to
which, A is a plate of metal ornamented or otherwise, which is bent in the centre;
the end of the lower or vertical portion being turned inwards so as to enclose a coiled
spring a the limb or arm 6 of which embraces the ledge of the music stand or rack B.
Pivoted to said plate at c is a loop C, pin, peg or equivalent, to the lower extremity
of which is adapted a weighted extension piece D.
Upon the leaf of the music or book being turned, the loop, pin, peg or equivalent C
is depressed, allowing the leaf to freely pass, whereupon the loop C is released and
by reason of the weight at D automatically resumes its normal vertical position, thus
preventing the return or displacement of said leaf.
Instead of the weight D 1 may employ a spring or equivalent flexible contrivance
to return said loop, pin, or peg C to its normal position; and, as a means for retaining
the music or book upon the stand or rack to which same may be adapted, I may

page_text: employ a strong wire or a rod placed vertically on the stand or rack which would
be caused to embrace the centre of the music or book by the tension of a spring
or the like.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:
In music or book holders the device herein described for retaining the leaves
of music or the like in position substantially as described and shown.
