PROVISIONAL SPECIFICATION.
An Automatic Bookmarker.
We HENRY VAUGHAN LANCHESTER 7 Balham Grove London S. W. Architect and
FREDERICK WILLIAM LANCHESTER 7 Balham Grove London S. W. Draughtsman do
hereby declare the nature of this invention to be as follows :-
Our invention relates to improvements in apparatus for facilitating rapid references
to books and by means of the said invention any place may be marked in a single and
automatic manner.
A simple form of our invention may be made by attaching the extremities of a
taps to each cover at or near the edge preferably either at the top or bottom and
which tape is of such length às not to interfere with the book being opened, this tape
is so arranged that when the book is open it lies in a more or less direct line between
its points of attachment but on closing the book it folds between the leaves thus
indicating the pages at which the book was last open.
The tape should be made of a sufficiently elastic material to ensure its returning to
its position between the leaves when the book is reclosed.
We do not however confine ourselves to the use of the before mentioned pattern
but may substitute for the tape a combination of links, cord, strap, band, or sheet of
suitable material, which will hereinafter be referred to as the marker.
When the marker is in the form of a sheet it is preferably attached to the top
edges of the covers along almost their entire length serving at the same time to
project the upper edges of the leaves from dust.
When the marker is not required to be used throughout the book, but only in a
portion of it, its ends may be attached to tongues or leaves made of cardboard or
other suitable material either bound in or laid in the book at the commencement and
end of the portion to which the marker is required, in this manner a book may have
any number of markers each serving a particular section and acting independently of
the others.
When the tongues or leaves before mentioned are used they may be extended beyond
the edge of the book and the protruding portion inscribed according to the section to
which it is contiguous.
The leaves of the book may be notched in order to receive the marker or
markers.
The marker may be attached to the covers, tongues, or leaves by knots, stitching,
glue, cement, some form of metallic fastener or other suitable means.

COMPLETE SPECIFICATION.
An Automatic Bookmarker.
We HENRY VAUGHAN LANCHESTER Architect and FREDERICK WILLIAM
LANCHESTER, Draughtsman, both of 13 Bedford Row, in the county of Middlesex,
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 facilitating rapid
references to books and consists in the use of a marker which when the book is open
does not materially interfere with the turning of the leaves, but which on closing the
book automatically inserts itself to a greater or less extent between the open pages

page_text: by its elasticity or otherwise thus indicating the place at which the book was last
open.
The marker consists of a strip of more or less resilient material having its two
ends attached to the cover and which lies immediately outside the top or bottom
edge of the book.
In the accompanying sheet of illustrative drawings
Fig. 1 is a cross sectional elevation of a marker constructed according to our
invention.
Fig. 2 is a side clevation of the same.
Fig. 3 is a section of a clip suitable for securing the marker on to the cover of a
book.
Fig. 4 shews the marker applied to a book and the position it takes as the hook
is being closed.
Fig.
is a similar view to Fig. 4 shewing the position of the marker when the
book is open and
Fig. 6 shews a modified construction of marker.
Referring to Figs. 1 to 5 inclusive, the tape B of elastic material and of such
length as not to interfere with the book being opened has its extremities attached
to clips A which are capable of being secured on the cover of any book to which it
is desired to apply the marker as shewn in Figs. 3, 4 and 5. The tape B is so
arranged that when the book is open it lies in a more or less direct line between its
points of attachment as shewn in Fig. 5, but on closing the book it automatically
folds between the leaves as shewn in Fig. 4 and indicates the page at which the book
was last open.
Referring to Fig. 3 a fold is formed in the clip at C to grip the band or tape B,
the end E is embossed to prevent injury to adjacent books, the inclined surface F
and spring G serve to obtain a firm grip on covers of different thicknesses.
When the marker is not required to be used through the whole of the book, the
ends of the tape B are attached to tongues or leaves either bound or laid in the
book at the commencement and end of the portion to which the marker is to be
applied. If desired, the clip A may be omitted and the tape B may be sewn or
otherwise fixed to the cover of the book.
In Fig. 6, the marker is shewn of a form suitable for its being made of sheet
metal in which case the necessary elasticity is conveniently given to it by forming at
its extremities right and left handed helical springs by means of which it is attached
to the clips A or otherwise to the cover.
Having now particularly described and ascertained. the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
:-
1. The arrangement of an elastic or resilient tape or band having its extremities
attached to the cover of a book or at the commencement and end of the part of the
book to be marked so that when the book is closed the said tape or band automatically
inserts itself to a greater or less extent between the pages to indicate the place at
which the book was last open substantially as described.
2. A book marker consisting of a tape of elastic material having its extremities
secured to clips constructed so as to be readily secured to the cover of a book
substantially as described with reference to Figs. 1 to 5 inclusive of the drawings and
for the purposes set forth.
3. A bookmarker consisting of a marker the extremities of which form springs
attached to clips capable of being readily secured to the cover of a book sub-
stantially as described with reference to Fig. 6 of the drawings and for the purposes
set forth.
