PROVISIONAL SPECIFICATION.
An Improved Method of and Appliance for Holding Removable
Leaves of Albums, Books, Letter Files, and the like.
I, ALEXANDER SINCLAIR COGHILL of 85 Middle Abbey Street, Dublin,
Ireland, Stationer, do hereby declare the nature of this invention to be as follows:-
My invention relates to means of holding the leaves of albums, books, letter files,
and the like, in such a manner that any leaf, letter or group of folded leaves can be
readily removed and replaced without interfering with the other leaves. For this
purpose, I fix at the back of the album, book, or letter file, a plate of metal of the
same length and breadth as the back, with a pair of parallel flanges at each end
projecting some distance forward, each pair having between them hinged at their
front edges a piece of metal which is bent to the shape of a V with its ridge
projecting inwards. On the back plate at each end there is a spring catch which
holds the V piece, but which can be pressed back by the finger, releasing the
V piece. The back plate, instead of being in one piece extending the whole length
of the back, may be made as two separate end pieces, each provided with its pair of
flanges, its pivotted V piece and its spring catch, thèse end. pieces being fixed in
any suitable way to the binding. I provide a number of thin strips, which may be
of cardboard, sheet metal, wood or other suitable material, each strip being as long
as the back of the book and as broad as the depth of the flanges. projecting from the
back plate, and having at each end a V notch to fit the V pieces above mentioned.
One of these strips being flexibly attached, by a strip of calico or the like, to the
back edge of a leaf of an album, or being placed in the fold of a letter or of a group
of folded leaves, can, on releasing one of the V pieces, be inserted between them,
and then on securing the V piece by its spring catch, it is held firmly, holding the
leaf or group of leaves, which however, on releasing one of the spring catches, can
be readily withdrawn when desired. One of the V pieces may be permanently
fixed to the back plate and its flanges, only the other being hinged and secured by
a spring catch.

An Improved Method of and Appliance for Holding Removable
Leaves of Albums, Books, Letter Files, and the like.
I, ALEXANDER SINCLAIR COGHILL, of 85 Middle Abbey Street, Dublin,
Ireland, 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 :-
My invention relates to means of holding the leaves of albums, books, letter files
and the like, in such a manner that any leaf, letter or group of folded leaves can be
readily removed and replaced without interfering with the other leaves, as I shall
describe, referring to the accompanying drawings.
Fig. 1 is a vertical section and Fig. 2 is a plan, Figs. 4 and 5 are perspective
views of an appliance according to my invention for holding a leaf partly shewn by
Fig. 3.
I fix at the back of the album, book or letter file, plates of metal of the same
length and breadth as the back or, as shewn in the drawings, two separate

page_text: plates A and B each having a pair of parallel flanges projecting some distance
forward. At the front edge of the flanges of A is hinged a piece of metal C which
is bent to the shape of a V with its ridge projecting inwards. On the pack plate A
there is a spring catch C' which holds the V piece C but which can be pressed
back by the finger releasing C.
be
may
The back plate B has also its pair of flanges and its V piece D which
hinged and provided with a spring catch but which, as shewn, is permanently fixed
to B. The plates A and B being fixed in any suitable way to the binding, I
provide a number of thin strips E which may be of cardboard, sheet metal, wood or
other suitable material, each strip being as long as the back of the book and as
broad as the depth of the flanges projecting from the back plates A and B and
having at each end a V notch to fit the V pieces C and D. One of these strips
being flexibly attached by calico F or the like to the back edge of a leaf G of an
album, or being placed in the fold of a letter or of a group of folded leaves, can, on
releasing the V piece C be inserted between the two V pieces, and then, on
securing the V piece C by its spring catch, it is held firmly holding the leaf or
group of leaves, which however, on releasing the spring catch, can be readily
withdrawn when desired.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is :—
1. The herein described method of holding removable leaves of an album or the
like, by means of strips attached to or folded within the leaves, and notched at their
ends so as to engage with V pieces attached to a flanged plate or plates secured to
the back of the album or the like.
'
2. In combination with the back and with removable leaves of an album or the
like, strips attached to or folded within the leaves and notched at their ends, a back
plate flanged at each end or a pair of flanged plates fixed to the back, and having
projecting V pieces to engage the notches of the strips, one of these pieces being
hinged to the flanges, and provided with a spring catch, or both being so arranged,
substantially as described.
