PROVISIONAL SPECIFICATION.
Improvements on Portable Music Cases.
I DAVID ALEXANDER PEARSON ANDERSON residing at No. 1 Livingstone Place
Edinburgh, Fancy Stationer do hereby declare the nature of this invention to be as
follows:-
Improvements on Music Cases of the half breadth size, that is, Music Cases which
when closed are only slightly broader than half the width of a sheet of music.
The improvements consist of (1st.) Elastic bands or bands of other material or wires
are arranged and fitted side by side along the case so that each sheet or piece of
music may be bound inseparately. This is effected by opening out each sheet 'or
piece of music and slipping it under one of the said bands or wires-a separate
band or wire being used for each sheet or piece-and so it is hinged or bound
into the case by its own natural fold in the same manner as a book is fitted into
a pocket-book. The case may then be closed on doubling up as a whole the music
contained in it.
"
(2nd.) The music does not require to be removed from the case in order to use
it, but the case may be laid on the music-stand of a piano or any other musical
instrument or on any music-stand in the same manner as a volume of music; and
by the simple means of turn-buttons, when necessary, each sheet or piece of music
while in use is kept flat and open, while the other sheets or pieces of music con-
tained in the case are slipped under a band or bar or roller running along the
case at or near its left and right extremities and so cause no inconvenience; that
is, the music to the left of the sheet or piece in use, is slipped under the band or
bar or roller at the left of the case and the music to the right of the sheet or
piece of music in use is slipped under the band or bar or roller at or near the
right extremity of the case.
3d. The case may further be provided with a back-stand or strut, so that it may
stand on a table and form in itself a music-stand.

Improvements on Portable Music Cases.
I, DAVID ALEXANDER PEARSON ANDERSON, residing at No. 1 Livingstone Place,
Edinburgh, Fancy Stationer 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 is for improvements in the construction of portable music cases, and
refers more particularly to music cases which when closed are only slightly broader
than half the width of a page of music of the ordinary size.
To render the invention clear, and that the improvements may be fully understood
I have illustrated them in the annexed sheet of drawings in which similar letters of
reference indicate similar parts in any of the figures, in which they occur.
Fig. 1, is a side and back view of a closed music case made after my invention.
Fig. 2, is a side view of an open case with the strut opened.
Fig. 3, view of interior of case.
Fig. 4 end of open case.
This invention relates more particularly to Music Cases which when closed as
shown in Fig. 1, are only a little broader than half the width of a sheet of music,

page_text: Supposing the boat B to be suspended from the davits as shown in the Figure and
that it is required to lower the boat, proceed. as follows-First, lower the boat through
the intervention of the davits and blocks in the usual way until the boat is just clear
of or in the water; then grasp the two loose ends a a* of the pendants a', which
may be of any suitable length but as short as possible, and gradually unreeve the
pendants from the cleat until for example the grip of the pendants on the cleat and
on the ring and eye bolts through which they pass is just sufficient to hold up the
weight of the bolt-and any practical seaman knows exactly what this means-
then, at the required moment, unreeve the last turn on the cleat when the pendants
will instantly run out and be left freely hanging from the blocks, the boat being
synchronously detached. It will be observed that to effect this manoeuvre success-
fully it is necessary to have a cleat of the novel type hereinabove specified as other-
wise there would be great risk of simultaneity of release not being efficiently
effected.
The lowering and detaching being thus accomplished the picking up is effected by
reeving the pendant ends through the ring bolts usually placed in the stem and stern
of boats and making fast round a thwart or through the ring or eye bolts or their
equivalent and back to the cleat through which and round which they may then be
passed and belayed as above described.
Being thus made fast the boat can be hauled up to the davits in the usual way.
It will be understood that I need not necessarily use the ring and eye bolt arrange-
ment hereinabove set forth as there might be cases where small leading pulleys might
with equal efficiency be substituted, but as most boats have ring bolts already fixed
at stem and stern I prefer to use these as guides or leaders to the central cleat.
Further there may be used instead of the cleat above described any simple and
convenient device for holding or gripping the pendant ends for example by jamming
the latter between metal surfaces by screw or other power but I do not specially
recommend such a device as the cleat is the simplest and best for the purpose that I
am now aware of. The pendant or rope between the central cleat and the eye
holts as a may be conveniently covered in by a light metal or other casing so as to
be out of the way.
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
claim is
(1) For lowering or detaching or picking up ships' boats the use of a cleat
traversed by a hole through which the pendant ends are rove and secured or released
substantially as and for the purposes hereinbefore set forth.
(2) The combination with a cleat such as is hereinabove described and illustrated
of guide rings or leaders arranged towards the ends of the boat through which the
pendants pass substantially as and for the purposes hereinabove set forth.
